Sky Mirror

Sky Mirror is a public sculpture by artist Anish Kapoor. Commissioned by the Nottingham Playhouse, it is installed outside the theatre in Wellington Circus, Nottingham, England. Sky Mirror is a 6-metre-wide (20 ft)-wide concave dish of polished stainless steel weighing 10 tonnes (9.8 long tons) and angled up towards the sky. Its surface reflects the ever-changing environment. It took six years from the initial idea for a major new piece of public art to the unveiling of Sky Mirror on 27 April 2001, and cost 900,000. At the time, it was the most expensive piece of civic art funded by the National Lottery. It was manufactured in Finland. In autumn 2007 the Nottingham Playhouse Sky Mirror was voted Pride of Place in a poll to find Nottingham's favourite landmark. More recently,[when?] Sky Mirror has been installed in Brighton's Pavilion Gardens for the Brighton Festival. From 19 September to 27 October 2006, a larger version of Sky Mirror was installed at Rockefeller Center in New York City. It had a 35 foot (11 m) diameter, stood three stories tall, and weighed 23 long tons (23 t). The convex side faced Fifth Avenue, the concave side the Rockefeller Center courtyard. Versions of Sky Mirror also exist in the Hermitage Museum in Saint Petersburg, Russia and De Pont Museum of Contemporary Art in Tilburg, the Netherlands. From 28 September 2010, Sky Mirror and three other Kapoor sculptures were exhibited in Kensington Gardens, London. The open-air exhibition was titled Turning the World Upside Down and it ran until 13 March 2011. It was accessible from 6 a.m. until dusk. Kapoor said that Kensington Gardens was "the best site in London for a piece of art, probably in the world". The location of Sky Mirror was previously occupied by a sculpture by Henry Moore - a work that was donated by the artist, but had been removed for conservation in 1996. Kapoor's sculptures are guarded round-the-clock at a cost estimated to be 120,000 paid for by the Royal Parks Agency.[needs update?] Sky Mirror's permanent installation is at Dallas Cowboys Art Collection at AT&T Stadium.

Do you think it is possible to paint around a mirror?

I paint houses and paint around mirrors all the time in bathrooms.really large mirrors at that. Do not waste your money on painters tape. Have a damp rag or damp paper towel handy while painting and if you get a spot on the mirror, immediately wipe it off before it dries.

Pieces of a Broken Mirror

"Pieces of a Broken Mirror" is the twelfth episode and midseason premiere of the fourth season and 78th episode overall from the Fox series Gotham. The show is itself based on the characters created by DC Comics set in the Batman mythology. The episode was written by executive producer Danny Cannon and directed by Hanelle M. Culpepper. It was first broadcast on March 1, 2018. In the episode, Gordon has been on a rough time after the events of the past episode. He investigates Lee's attempted assassination by a man who employed a toy plane charged with a bomb. After he and Fox survive another assassination attempt at his toy workshop, he looks to identify the suspect, who has been secretly employed by one of Lee's trustees. Meanwhile, after being fired by Bruce, Alfred has been living in the Narrows for a time, for which he begins to befriend a friendly waitress in a diner but soon discovers she is living with her abusive boyfriend. Also, Ivy Pepper is reborn into a new physical form. The episode received mostly positive reviews from critics, who praised Cory Michael Smith's performance, the writing and the great blend of the storylines together.

The segments can be either spherical or asymmetric (if they are part of a larger parabolic reflector). They are used as objectives for large reflecting telescopes. To function, all the mirror segments have to be polished to a precise shape and actively aligned by a computer-controlled active optics system using actuators built into the mirror support cell. The concept and necessary technologies were initially developed under the leadership of Dr. Jerry Nelson at the Lawrence Berkeley National Laboratory and University of California during the 1980s, and have since spread worldwide to the point that essentially all future large optical telescopes plan to use segmented mirrors.— — — — — —Semiconductor saturable-absorber mirrorSemiconductor saturable-absorber mirrors (SESAMs) are a type of saturable absorber used in mode locking lasers. Semiconductor saturable absorbers were used for laser mode-locking as early as 1974 when p-type germanium is used to mode lock a CO2 laser which generated pulses of around 500 picoseconds. Modern SESAMs are III-V semiconductor single quantum well (SQW) or multiple quantum wells grown on semiconductor distributed Bragg reflectors (DBRs). They were initially used in a Resonant Pulse Modelocking (RPM) scheme as starting mechanisms for Ti:Sapphire lasers which employed KLM as a fast saturable absorber . RPM is another coupled-cavity mode-locking technique. Different from APM lasers which employ non-resonant Kerr-type phase nonlinearity for pulse shortening, RPM employs the amplitude nonlinearity provided by the resonant band filling effects of semiconductors. SESAMs were soon developed into intracavity saturable absorber devices because of more inherent simplicity with this structure. Since then, the use of SESAMs has enabled the pulse durations, average powers, pulse energies and repetition rates of ultra-fast solid-state lasers to be improved by several orders of magnitude. Average power of 60W and repetition rate up to 160GHz were obtained. By using SESAM-assisted KLM, sub-six-femtosecond pulses directly from a Ti: Sapphire oscillator were achieved. Ursula Keller invented and demonstrated the semiconductor saturable absorber mirror (SESAM) which demonstrated the first passively mode-locked diode-pumped solid-state laser in 1992. "For almost two decades since then, her group at ETH Zurich has continued to define and push the frontier in ultrafast solid-state lasers both with detailed theoretical models and with world-leading experimental results, demonstrating orders of magnitude improvement in key features such as pulse duration, energy, and repetition rate. She also helped to spearhead industrial transfer of this technology. Today most ultrashort lasers are based on SESAM modelocking, with important industrial applications ranging from optical communication, precision measurements, microscopy, ophthalmology, and micromachining." A major advantage SESAMs have over other saturable absorber techniques is that absorber parameters can be easily controlled over a wide range of values.[quantify] For example, saturation fluence can be controlled by varying the reflectivity of the top reflector while modulation depth and recovery time can be tailored by changing the low temperature growing conditions for the absorber layers. Fiber lasers working at 1 µm and 1.5 µm were successfully demonstrated.[irrelevant citation]

Happy mirror designing.— — — — — —Concave mirrorsA concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror. These mirrors are called "converging mirrors" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles at different spots on the mirror as the normal to the mirror surface differs at each spot. Uses of concave mirrorsConcave mirrors are used in reflecting telescopes. They are also used to provide a magnified image of the face for applying make-up or shaving. In illumination applications, concave mirrors are used to gather light from a small source and direct it outward in a beam as in torches, headlamps and spotlights, or to collect light from a large area and focus it into a small spot, as in concentrated solar power. Concave mirrors are used to form optical cavities, which are important in laser construction. Some dental mirrors use a concave surface to provide a magnified image. The mirror landing aid system of modern aircraft carriers also uses a concave mirror. Concave mirror image

Developed by Carl Gottfrid Fineman this instrument consists of a magnetic compass, the case of which is covered with a black mirror, around which is movable a circular metal frame. A little window in this mirror enables the observer to see the tip of the compass needle underneath. On the surface of the mirror are engraved three concentric circles and four diameters; one of the latter passes through the middle of the little window. The mirror constitutes a compass card, its radii corresponding to the cardinal points. On the movable frame surrounding .the mirror is fixed a vertical pointer graduated in millimeters, which can be moved· up and down by means of a rack and pinion. The whole apparatus is mounted on a tripod stand provided with leveling screws. To make an observation, the mirror is adjusted to the horizontal with the leveling-screws, and is oriented to the meridian by moving the whole apparatus until the compass needle is seen, through the window, to lie in the north-south line of the mirror (making, however, allowance for the magnetic declination). The observer stands in such a position as to bring the image of any chosen part of a cloud at the center of the mirror, lind the vertical pointer is also adjusted by screwing it up or down and by rotating it around the mirror until its tip is reflected in the center' of the mirror. As the image of the cloud moves toward the circumference of the mirror the observer moves his head so as to keep the tip of the pointer and the cloud image in coincidence. The radius along which the image moves gives the direction of the cloud's movement, and the time required to pass from one circle to the next its relative speed, which may be reduced to certain arbitrary units. This instrument is, however, not very easy to use, and gives only moderately accurate measurements.

Abstract: This article discusses how light could be stored, so that you can take it with you and use it at some later time. These thoughts very nicely show you how a laser works. With this article, I want to show you a nice way to understand the basic operation principles of lasers - either for your own pleasure or when you try to explain it to beginners. We begin by asking a seemingly unrelated question: How can we store light? Could we put some amount of light into some suitable kind of bucket, with which we could carry it around and use it later on? An essential problem with storing light is that it moves away so fast. A relatively straightforward idea is to confine the light with some mirrors, which prevents it from escaping. In the simplest case, we would just use two highly reflecting mirrors in parallel, so that a light beam can be captured between those: Such an optical arrangement is called an optical resonator. Ideally, the light would be perfectly reflected by the mirrors and circulate there forever. One can easily imagine a number of problems with that approach, which however we will solve step by step. The first concern is that during many round trips the circulating light beam would diverge more and more, i.e., develop a larger and larger beam diameter, so that eventually it reaches the edges of the mirrors, and part of the light gets lost. There is a simple solution to that: just make one or both mirrors slightly curved, so that the circulating light beam is constantly refocused: With slightly curved end reflectors, the divergence of the beam can be kept under control. With the proper amount of refocusing, the natural tendency of the beam to diverge can be fully compensated. You might think that it is difficult to obtain exactly the right amount of refocusing. However, within some limits you can just choose some mirror curvatures, and there will always be a so-called resonator mode fitting to the setup. (Actually, there are normally many such resonator modes, having different intensity profiles.) One might think that perfect alignment of the mirrors is a prerequisite for storing the light over longer times. This is not the case, however: if you slightly tilt one mirror, for example, there is a correspondingly shifted version of our light beam which can still stay on that position for a long time. You may even slightly change the alignment while the beam is in the resonator, and the beam will be able to adjust to the new mirror positions as long as the movements are sufficiently slow - which is easy to guarantee, given that light is much faster than you can move any solid parts. Only if you misalign the resonator too much, the beam will reach the edges of the mirrors, and this results in strong power losses. This is the most serious concern: in each round-trip, the light will lose some of its energy, since the mirrors can never be perfectly reflecting, and there might be further power losses e.g. by scattering in the air. This problem becomes quite severe due to the very high velocity of light. For example, if the spacing of the mirrors is 1.5 m, the round-trip time will be only 10 ns, so that the light beam makes 100 million round trips per second. So even if you use so-called supermirrors with an excellent reflectivity of 99.999999%, within one second you will lose most of the circulating light energy. If you use ordinary laser mirrors with a reflectivities of 99.9%, it will only take the order of 100 round trips to lose most of the energy - these will be completed within only a microsecond. If you make the resonator shorter, that fading away of the energy happens even faster. Using a very long resonator would help in principle, but is not very practical. This problem can be solved with the following trick: between the mirrors, put some medium which can not only transmit the light, but also amplify its power. For the moment, just imagine that you have some magic kind of crystal, which could amplify the light power by 10% in a single pass. That would be sufficient to compensate losses of 10% on each mirror, if no other losses occur (e.g. during propagation in air). By inserting and amplifying crystal into the resonator, we can compensate the power losses. Of course, the balance of optical gain (amplification factor) and losses is then quite delicate: If the gain of your amplifier a slightly too low, there will still be some net losses per round trip, and the light energy will soon be lost. If the gain is slightly too high, there will be a positive net gain per round trip, and as a result the circulating optical power will rise exponentially. Given the very small round-trip time, the optical power might reach enormously high levels within a short time. Actually, there is no risk that you will be killed by a disastrous power level arising from that setup, since there is no amplifier which can achieve a certain gain for arbitrarily high input powers. Any amplifier will exhibit some kind of gain saturation, i.e., its gain will drop under such conditions. If the circulating optical power rises and rises, the gain will eventually drop to the level which is needed to just keep the circulating power constant. It should not take long to reach that steady state, again because the light circulates so fast. It has not yet been explained how such a magic amplifying crystal could be obtained. I will discuss that in detail in the next posting of the Photonics Spotlight. For now, I just tell you that some amount of power is required to operate such an amplifier; after all, it constantly adds energy to the optical field. If it is a transparent crystal, which is not electrically conducting, the only reasonable way to supply such power is to shine light on it - for example, from the side. You should then have something in the crystal which can absorb that pump light and utilize it to provide the required gain. How to Get the Light In? There is only one problem remaining: how can we initially get the light in? It is of course not realistic to think that you could take off one of the mirrors, shine some light in and then quickly enough put the mirror on again. Also, you cannot put an ordinary light source into the resonator without blocking the circulating light. Fortunately, you actually do not need to do anything to solve that problem, because you already have a light source in the resonator! Just turn on your optical amplifier, and it will produce a tiny amount of light even when there is nothing yet to be amplified; that phenomenon is called fluorescence. Beginning with that very small amount of light, the amplifier will now quickly increase the power until the above explained steady state is reached. How to Make This Device Useful? We have now managed to find a way for storing light over long times - even though we constantly need to supply energy in order to compensate for the permanent losses. In this sense, it is like a not perfectly insulated storage tank for hot water, which you permanently need to heat in order to keep it hot. In the current form, however, the device is not particularly useful: there is some light captured between the mirrors, but you cannot do much with it. For example, you cannot put some absorbing workpiece into your resonator in order to irradiate it, since that would simply switch off the device. The thing becomes much more useful with a small modification: instead of highly reflecting mirrors, use at least one which transmits a certain percentage of the circulating power - for example, 10% of it. If the other mirror is highly reflecting, you will have about 10% power loss for the circulating light per round trip - which can be compensated if the amplifier can provide that amount of gain. Through that partially reflecting mirror, you now obtain an output light beam which you can use. If one end mirror is partially transmissive, we can obtain a useful output beam. The device which we have got has (unfortunately) been invented and named already by others: it is called a laser! In the following, we will discuss some of its basic properties. In order to obtain a substantial output power, you want to use an output coupling mirror having a substantial transmission. Only, you should not overdo that, because the more transmission you have, the lower will be the reflectivity and the higher the round-trip loss of the resonator will be; if you couple out too much, the available amplifier gain will no longer be sufficient, and the device will not work. If you work with a fixed mirror set and vary the amount of pump power supplied to the amplifier, you will get the following: Below a certain amount of pump power, which is called the laser threshold power, the gain is too low to compensate the losses. You will then obtain nearly no output at all - only a very weak amount of fluorescence light, much of which is emitted in all sorts of directions. Above the laser threshold, most of the emitted light is contained in the mentioned output beam, although a little power is still emitted in all directions. For higher pump powers, the output power often rises about linearly. The slope of that line is called the slope efficiency. Laser action only occurs above a certain threshold pump power. The displayed numbers refer to the example case of a low-power diode-pumped Nd:YAG laser. In many cases, it is possible to obtain laser emission in a single spatial mode of the laser resonator. This results in a high spatial coherence and a very high beam quality of the output beam: particularly if the beam radius at the laser output is not too small, its beam divergence is very small, so that the beam radius rises only slowly. However, not all lasers can be made to admit with a high beam quality; examples for that are high-power laser diodes and lamp-pumped high-power solid-state lasers. In many cases, the emission bandwidth of a laser is very small, and the temporal coherence correspondingly high. This is because there is some wavelength dependence of the amplifier gain, and the laser will then operate only in a narrow range of wavelengths where the gain is highest. Lasing at other wavelengths is suppressed, even if these have an only slightly lower gain: the laser light saturates the gain so much that the net round-trip gain is exactly zero for the optimum wavelengths. Any other wavelengths will see a negative round-trip gain, so that such light would be quickly fading away. By using quite sophisticated means, one can optimize lasers for obtaining even a much reduced emission bandwidth. In some cases bandwidth values below 1 Hz are achieved - which is very remarkable considering the mean emission frequency of hundreds of terahertz. Such high precision lasers are used in optical frequency metrology, e.g. for making the most precise laser clocks. Some other lasers are optimized for broadband emission. For example, this often happens in the context of mode-locked femtosecond lasers; see our article on mode-locked lasers. Sometimes, one further broadens the emission bandwidth with external means; see the article on supercontinuum generation. If the laser gain medium is pumped continuously, the laser output will also usually be continuous. However, one can apply additional tricks for obtaining short or even ultrashort laser pulses. For example, one can employ the method of Q switching: one suppresses lasing for some time by somehow causing a strong additional resonator loss and then suddenly switches that loss to a much lower level. Laser action will then begin and lead to an output pulse which often has a pulse duration of only a couple of nanoseconds, a substantial amount of pulse energy and a correspondingly high peak power - sometimes many gigawatts. Another method is mode locking, where one has an ultrashort circulating pulse in the laser resonator and obtains one output pulse for every resonator round trip - for example once every 10 nanoseconds. The pulse duration can then easily be a few picoseconds or under best conditions down to roughly five femtoseconds - an enormously short time. I hope you have enjoyed these explanations and will make others aware of them. In the next Spotlight article, I will explain how the optical amplifier works, which is needed for any laser.

Is the Traditional Energy-saving Lamp Regulator Used for LED Circuit? Detailed Analysis of 11 Defect
Can the controller of traditional energy-saving lamp act on LED circuit?There are many options for buying LED bulbs, but compatible led dimmers are difficult to choose. Many users will confidently say that it is OK to use the dimmer of traditional incandescent lamps. Now the most commonly seen on the market is thyristor dimmer, which is divided into DC and ac. it is very easy to use in incandescent lamps.After selecting the LED lamp with appropriate color temperature, lumen grade and beam angle, the dimming requirements are met. Different from the random dimming method of ordinary incandescent lamps, dimming LED bulbs with thyristors may be successful, but many problems will occur in most cases.Four conditions:The most common problem is that there is a buzzing beep or a strong stroboscopic. Ordinary incandescent lamps only need to adjust the voltage to adjust the light and shade, but it may not work for LED lamps. We have done experiments and the following four situations have occurred:1. It can't be opened at all. It doesn't light up at all!2. It can only be on at 100% illumination.3. It can work normally, but the buzzing sound is very loud.4. Stroboscopic occurs when it is adjusted to a certain brightness.Dimming principle:During the test, sometimes the LED can be used normally after it is dimmed to a certain limit. We judge that the reason why it doesn't light up is that the applied voltage of the dimmer is too small to reach the required voltage.The internal circuit of LED is much more complex than that of incandescent lamp. The real led dimmer is not only regulating voltage, but also has three principles:1. Wave width control dimming: digitize the square wave of the power supply and control the duty cycle of the square wave, so as to control the current.2. Constant current power supply regulation: the current can be easily adjusted by analog linear technology.3. Grouping control: group multiple LEDs and control them with a simple grouping device.Note the strobe:The reasons for the most stroboscopic cases are as follows: the adjustable resistor itself is not a very reliable component. Often, due to the entry of dust or the lax manufacturing process, there will be an instant jump fault when operating the adjustable resistor, and the light source will flash. Therefore, we need high-quality adjustable resistance, or use linear technology to regulate current rather than voltage.In fact, the internal driving function of LED itself can easily adjust the brightness and darkness, but most LED manufacturers remove this function to save costs. Whether the LED lamp can be dimmed is usually marked on the box. If there is no mark on the box, please use the dimming function with caution or use a special LED dimmer.Dimming will reduce life:A reminder is that dimming can easily reduce the life of the bulb. Why? Simply take a dimming method: we divide one second into 1000 parts, each part is 1 millisecond, and then make the LED light work for 7 milliseconds and turn off for 3 milliseconds through the control chip. In this way, it only works for 0.7 seconds in one second. However, due to the fast flashing interval, we can't feel its brightness flickering with our naked eyes, and we will only feel that its brightness has darkened, which is 0.7 times the original, This achieves the effect of dimming. Similarly, we can achieve 50% brightness, 32% brightness and any brightness. Blink in this way, it's strange not to break early!In order to avoid various problems, try not to use the physical dimming method for the smart bulb. Take out the mobile phone and open the app to adjust the light and shade.In fact, I still like to use the way of grouping device to control the brightness, which is simple, safe and easy to use. It can be easily done by touching the key switch or independent grouping switch. It is not necessary to fine tune the brightness from 0 to 100% perfectly in the home. It is OK to realize several levels of brightness adjustment, which can fully meet the needs.Analysis and retrieval of 11 disadvantages of LED wick:Compared with traditional incandescent lamps, led filament lamps have higher requirements for packaging. It is reported that at present, led filament lamps have very strict requirements for filament working voltage design, filament working current design, LED chip area and power, LED chip luminous angle, pin design, glass bulb sealing technology, etc. it can be seen that the manufacturing process of LED filament lamps is very complex, and there are certain requirements for the financial strength, supporting facilities and technology of manufacturers.In the production process, due to different processes, the requirements for materials are also different. In addition, in production, many equipment need to be transformed according to the performance characteristics of LED filament lamps, which also makes the manufacturers of relevant materials of LED filament lamps miserable. The defects in the bulb material also make the LED filament lamp easy to be damaged during transportation. The complex process and low yield make the LED filament lamp unable to obtain high praise from manufacturers and consumers.1. Difficult process, poor heat dissipation and easy damageAlthough led filament lamps have attracted much attention in the domestic market in the past two years, at present, the problems existing in the production of LED filament lamps can not be ignored: the manufacturing process is difficult, several different processes need to be integrated, and the yield is low; More than 8W led filament lamps are prone to heat dissipation problems; It is easy to be broken and damaged in the process of production and use.2. Structure, performance and price to be improvedDue to the relatively late entry of LED filament lamps into the market, the market-related sharp bubbles, tail bubbles and spherical bulbs are mainly "patch type". In addition, the filament lamps that entered the market in the early stage are far from consumers' expectations in terms of structure, performance and price, which makes consumers have some misunderstandings about led filament lamps. With the breakthrough of key technologies, the maturity of packaging technology and the improvement of bubble sealing technology, the luminous efficiency, finger display, service life and cost of LED filament lamps will be improved to a certain extent.At present, the LED filament lamp needs to be improved in too many places. It is like a newborn "premature baby". It is not very mature in all aspects, with high cost, complex production process and low production capacity. Therefore, we should improve the raw materials, led beads and manufacturing process in the future, so as to improve the production capacity of LED filament lamps, reduce losses and improve delivery efficiency.3. Low power and poor heat dissipation are obstaclesAffected by the production process, there are many problems in LED filament lamps, such as high cost and high damage rate during transportation due to the defects of bulb material. In addition, the heat dissipation of high wattage led filament lamps has also become an obstacle for LED filament lamps to enter ordinary people's homes.Problem 2: high priceAccording to the market survey, the average retail price of a 3W led filament lamp is about 28-30 yuan, which is much higher than that of LED bulb lamps and other lighting products with the same power, and several times higher than that of LED incandescent lamps with the same power. Therefore, many consumers are scared away by the price of LED filament lamps.At this stage, the market share of LED filament lamps is less than 10%. Nowadays, as a characteristic product, led filament lamp restores the luminous feeling of traditional tungsten filament lamp and is loved by many consumers. However, the high cost, low light efficiency and small application range of LED filament lamps are also the problems that lighting manufacturers must face and look directly at in the next stage.1. Supporting materials increase product costThe market prospect of LED filament lamp is very bright, but there are difficulties in the promotion of LED filament lamp at this stage, mainly due to its high cost and the lack of large wattage, which makes the application of LED filament lamp limited to the flower lamp market. In addition, the matching of raw materials also increases the cost, because there is no standard in the specification and shape of filament lamp, and its market volume is small, As a result, the supporting materials are basically customized, and the manufacturing cost remains high.2. The cost of LED filament is too highAmong all parts of LED filament lamp, the highest cost is led filament, mainly because of its complex production process and high cutting cost; The production efficiency is not high and the degree of automation is low, resulting in the cost. At present, the cost of 3-6w filament bulb can be controlled below 15 yuan, of which the cost of LED filament accounts for more than half.3. The packaging of LED filament lamp is exquisiteThe packaging of LED filament lamps is more exquisite. The light effects encapsulated by each enterprise are different. Led filament lamps still have certain limitations in power and heat dissipation, resulting in higher prices than ordinary LED light sources.Problem 3: small marketAt this stage, the power of the best-selling led filament lamp in the market is basically less than 10W, which shows that at this stage, the LED filament lamp is technically trapped in the problem of heat dissipation and can not achieve high power. It also shows that it can only cover a small section of the whole lighting product line and can not be widely promoted. Even if it plays the "nostalgic" brand, the LED filament lamp market is only a small market, It can't become the mainstream for the time being.1. Low consumer acceptanceWith the shrinking incandescent lamp and energy-saving lamp market, LED lighting products are slowly recognized by end consumers. However, at present, the market of LED filament lamps is still very limited. Due to the limited application and power of LED filament lamps, the acceptance of LED filament lamps by end consumers is not very high.In addition, consumers do not know enough about led filament lamps. Many people think it is just an improvement of ordinary incandescent lamps.2. The main demand comes from the projectAs LED filament lamps are mainly used in flower lamps, and their main demand comes from engineering lighting, general dealers will not mainly promote LED filament lamps. Even if a few businesses sell LED filament lamps, they won't have too much inventory.Problem 4: difficult to promoteEntering the terminal market, we can find that the LED filament lamp is not as hot as expected for two reasons:1、 Many stores do not promote filament lamps as key products, and consumers' awareness and acceptance of filament lamps are not high;2、 Compared with LED light source products such as bulb and sharp bulb, led filament lamp products have no qualitative change. On the contrary, the price is relatively high and it is difficult to go. Let alone replace the market position of LED bulb, energy-saving lamp and other products.Therefore, at present, the market advantage of LED filament lamp is not very obvious, and the market is basically waiting and trying.At present, the difficulty of pushing led filament lamps in the terminal market lies in:1、 Poor integration between traditional bubble sealing industry and LED packaging industry (concept and process integration);2、 It is not easy to reverse the concept of end consumers;3、 The acceptance of LED filament lamp products by society and government is not clear. In addition, the price of LED filament lamp is high, and consumers have not really distinguished the difference between LED filament lamp and incandescent lamp, which leads to the difficulty of LED filament lamp market promotion.1. Merchants are not active in promotionAt present, if led filament lamps want to achieve good performance in the market, they also need to strengthen publicity and innovation. The development of LED industry is increasingly fierce, and industry standards have been issued one after another, which has exacerbated the market development resistance of LED filament lamps. Especially at this stage, many consumers do not understand led filament lamps, and merchants are not active enough in promoting led filament lamps. Even most merchants are not very optimistic about their development prospects. In actual sales, customers usually see or ask, Businesses will push this product.2. High price makes promotion difficultAt present, it is difficult to promote LED filament lamps in the market. Because consumers do not know much about led filament lamps, the probability of purchase is very small. In addition, due to the impact of e-commerce, the transaction rate of LED in physical stores is lower. Some consumers pay more attention to the price when purchasing products. Therefore, there is still a long way to go for LED filament lamps to enter the families of ordinary consumers.3. Lack of new selling points of LED filament lampsAt present, led filament lamp is in the primary stage of promotion, and very few people know its advantages because of the appearance and original quality of the product

IT'S an ongoing debate amongstwomen far and wide: is it really worth splurging on luxury make-up?With the news this week thatone in three women are putting make-up ahead of household bills, we have brought in make-up artist Sophie Fleur Thorp to partake in a blind testso that we canreach some kind of a conclusion...Cheap ThrillsMiss Sporty Mission Correction Multi-Action Foundation in Medium, £2.99MUA Blusher in Cupcake, £1Collection Velvet Kiss Moisturising Lip Cream in Mulberry, £2.99MUA Intense Glitter Eyeliner in Starry Night, £1Collection Extreme Coloured Lengthening Mascara in Black, £2.99Total: £10.97The Verdict“The three-in-one foundation concealer is quite disappointing. The texture is too thick, yet it doesn’t conceal imperfections and, instead of highlighting the skin, it leaves it looking matte. I struggled to build this up to hide problem areas without it looking caked on, so I’d recommend using a separate product to blur or hide any blemishes. The mascara is OK, although it doesn’t offer anything special and needs to be layered up to really get the volume and length I desire. The real winners are the liquid lipstick – it doesn’t budge and the pigments are vibrant – and the blusher, which delivers intense colour with a subtle shimmer. The eyeliner is also great. For a kohl pencil, it went on smoothly, with little pressure or pulling, and I was able to build it up and blend it out to create a glittery, smoky eye.”Mid-range MagicMax Factor Miracle Match Foundation Blur & Nourish in Caramel, £12.99Gosh Natural Blush in Electric Pink, £7.99Sleek Makeup Cleopatra’s Kiss Highlighting Palette, £9.99Rimmel London Lasting Finish Lipstick by Kate Moss in 005, £4.99Soap & Glory Supercat Easy Precision Black Ink Eyeliner, £6Bourjois Volume Reveal Mascara in Radiant Black, £9.99Total: £51.95The Verdict“I love that I can build up the foundation to disguise imperfections without needing a separate concealer. And the highlighting palette is going straight into my kit! The cream and powder combo is great, as you can mix them together to intensify the glow, plus it also doubles up as a shimmery eyeshadow. The mascara gave my lashes amazing volume and comes with a handy mirror – great for on the go. The lipstick is also impressive as it has the perfect balance of strong pigments and moisture, making it last all day. I wasn’t keen on the eyeliner, though. It took ages to dry, and left smudges and an imprint every time I blinked.”Super SplurgeYSL Touche Éclat Le Teint in BD60, £32.50Urban Decay Naked Skin Weightless Complete Coverage Concealer in Medium Neutral, £17.50Estée Lauder Pure Colour Envy Sculpting Blush in Plush Petal, £29Marc Jacobs Kiss Pop Lip Colour Stick in Headliner, £24Nars Unrestricted Matte Eyeliner Stylo in Black, £21Charlotte Tilbury Legendary Lashes Mascara in Black Vinyl, £25Total: £149The Verdict“Although this foundation didn’t make the same promises of concealing and highlighting as the other two did, it offered both and then some.My skin felt smooth, hydrated and illuminated – and there was little need for concealer. The blush palette offers a gradient of colour, meaning that you can both highlight and blush in one sweep. However, the shade was too light and blurred into the highlighter, so didn’t give the result I wanted. I wasn’t keen on the bullet shape of the lipstick – I prefer a hard edge, so you can get a clean line along your pout. The eyeliner went on well and dried immediately, and I was blown away by the mascara!

How Does Money Laundering Work?
How Does Money Laundering Work?
How does money laundering work?Here's how it works: The problem with money generated from crime- especially large scale organised crime- is that you need to have some explanation as to where the money is coming from, otherwise you will raise suspicion with the authorities. Money laundering is the process of disguising this illegally obtained money as legitimate profits, which you can then use without attracting attention. The most common way to do this is for criminals to own some kind of legitimate business, normally called a "front". They can then disguise their illegal money as profits obtained by this business. For example, suppose you owned a nightclub and charged entry to get in. In a typical night, perhaps you get 200 patrons. A money launderer might instead record that they had 400 patrons per night, and enter their illegally obtained money as entry fees for the 200 fake customers. They can now say they obtained the money legitimately as part of their business. Obviously, this is entirely illegal, and many organised criminals are brought down by money laundering and related charges, rather than for their other crimes. As such, you have to be very careful when doing. Good money-laundering operations use fronts that do not use up too many physical resources, so it's hard to confirm how much of its business is legit.— — — — — —Money laundering: how banks stay one step ahead of criminal activityMoney laundering is a technique used by criminals-from mobsters, drug traffickers, terrorists, to corrupt politicians-in order to cover their financial tracks after illegally obtaining money. It's well-known that money laundering can often involve foreign banks and legitimate businesses-so how do banks actively prevent money laundering from happening? The answer? Anti-money laundering. Anti-money laundering is a way for banks and other financial institutions to detect suspicious activity. By doing so, they help prevent criminal profits from becoming camouflaged and integrated into the financial system. Here's the lowdown on the techniques banks use to fight back against criminal financial activity. Money laundering is a process that disguises the source of criminal money in order to make it appear legal. Since 1990, money laundering itself has been a crime-and it's easy to see why. Money laundering is big business, with an estimated €740 billion to €2 trillion laundered each year. That's an eye-watering 2% to 5% of the global economy. In the EU alone, €197.2 billion is laundered each year. Profits gained from criminal activity is often known as "dirty" money, because it links directly to the crime and can be traced. In particular, lugging around physical cash-think dodgy deals and briefcases filled with bank notes-is far from logistical. Criminals need to "clean" the money, so that it can appear legal and be used for investments without fear of being caught. That's what money laundering is-"washing" dirty money to make it clean. Money laundering typically follows a basic three-step process. The first step is placement-this is the point where dirty money first enters the financial system. Layering then hides the source of the money using various bookkeeping tricks. And once the source of the money has been successfully disguised, comes the last step-integration, when clean money can be withdrawn or invested. Money laundering techniques vary in complexity. The most common method is to process dirty money through another cash-based business. Many criminal organizations own multiple "front organizations," from restaurants to casinos. Legitimate profits from these businesses mix with criminal money, hiding the source. Breaking Bad fans will remember Walter White purchasing the A1A Car Wash to launder the money that he made from his drug business. Another technique is called structuring, which is the act of dividing large sums of money into smaller amounts and spreading them across multiple accounts. Anti-money laundering policy in the EU means that transactions of €10,000 and higher are investigated. Structuring bypasses this by depositing multiple smaller amounts that appear less suspicious. Other techniques used by money launderers include: • None Currency exchanges where dirty money is exchanged by foreign currency providers. The provider may be unaware of the money's origin, or that the cash-based business is a front organization. • None Real estate purchases allow criminals to transform their money into houses and business property, which can later be sold. • None The art industry has also been targeted for money laundering, due to its levels of secrecy and the potential for high-value items. In 1989, the Financial Action Task Force (FATF) was created to combat money laundering. The FATF organization sets the framework for anti-money laundering (AML) policies, and supervises countries to make sure that they comply. Individual countries also have their own supervisory schemes that oversee national institutions. Globally, the UN, World Bank and International Monetary Fund all have AML schemes in place. Anti-money laundering is a framework for putting best practices into action in order to detect suspicious activity. The easier it is for criminals to spend illegal money undetected, the more likely they are to commit crimes in the future. As a result, AML regulations make "obligated entities" be aware of red flags to watch out for, and makes sure that such institutions proactively monitor their clients' activities. But who exactly are the "obligated entities?" Obligated entities refers to institutions that encounter financial transactions, which could be targeted by money launderers. These include banks, payment processors, and gaming or gambling businesses. In the EU, the European Banking Authority sets guidelines and regulations on supervision. Anti-money laundering supervisors then monitor each individual institution to see how effectively they carry out their AML tasks. Institutions have to comply with customer due diligence. The Anti-Money Laundering Directive (AMLD) is a EU-wide law that provides a framework for institutions across Europe. Transactions between "high risk" countries and transaction amounts of €10,000 or more are carefully monitored. Suspicious activity is then reported. As the foundation of the financial system, banks need a sharp eye to spot suspicious behavior. Like all institutions, banking AML policies are shaped by the framework set by the FATF. Frontline employees are trained in anti-money laundering techniques and are legally required to report suspicious activity. Banks may hire employees whose purpose is to boost anti-money laundering practices. These security experts are known as AML compliance officers. In addition, AML banking is supported by three key factors: identity checks, AML holding periods, and AML transaction monitoring software. Specific institutions, such as banks, are required to follow Know Your Customer (KYC) processes. These are the steps that banks must take to verify the identity of their customers. Although anti-money laundering policies provide the framework, individual banks are responsible for their own customers, and it's their responsibility to flag high risk transactions. So what do banks verify? Know Your Customer policies require banks to verify the customer's name, date of birth, address, and occasionally additional information, such as occupation. Banks typically ask customers to verify their identity with ID documents when opening an account. More recently, banks are using biometric identification, such as face or voice recognition, and fingerprint scans. Another tactic to help prevent money laundering is the AML holding period. This is a policy where deposits must stay in an account for a minimum of five trading days. Slowing down the process assists with anti-money laundering measures, and allows more time for risk assessments to take place. Many banks have millions of customers, and oversee millions of transactions. With such a high volume, it's impossible to manually monitor every single transaction. That's where AML transaction monitoring software comes in-this technology allows banks and other financial institutions to monitor transactions on a daily or real-time basis. Such software combines different sources of information, such as the account holder's history, risk-assessment, and the details of individual transactions such as the total sum of the money, countries involved, and the nature of purchase. Transactions can include cash deposits, wire transfers, and withdrawals. When a transaction is deemed to be high risk, it's flagged by the system as suspicious activity.
The Benefits of Water Dispenser for Your Business
The Benefits of Water Dispenser for Your Business
Just so you know, here's how your color coding looks to those with protanopia, the most common form of red/green colorblindnessI am currently trying to come up with an intuitive design for a touch free sink faucet that allows for both hot and cold temperature settings. Most touch free sinks involve one sensor to start the water flowing and you're stuck with whatever temperature comes out, which is usually just a mix of the two. After some research I found some designs incorporated a knob on the side to allow temperature settings, however in public restrooms a truly hands free design is strongly desired even if youre about to wash them, hence the invention of hands free soap dispensers even though it is putting sanitizing soap on your hands after touching it.The initial design I thought of was something like this:The user puts their hand over red sensor to start hot water, blue to start cold, both to start medium.However, there are some obvious oversights:The sensors aren't in front of the faucet, so they will keep stopping forcing you to wave over them again.The "medium" setting is not very intuitiveTo fix number one I added the middle black sensor, that way you activate the temperature states first by waving over the colored sensors, and then the water starts when you wave in front of the black one like typical hands-free faucets.However, I believe this to be even less intuitive and too many steps to simply wash your hands.So, are either of these designs intuitive or is there a more streamlined and easily understandable way to incorporate hot and cold functionality into a truly hands free faucet?

Starting with the issue of how much time we spend indoors, I then wrote about kitchen ventilation, the panoply of indoor air pollutants, problems with filters in general and with high-MERV filters. Now let's take the next step: a look at what research has been done on high-MERV filters and what can be done to overcome those unintended consequences I wrote about. In this article, John Proctor summarized some of the results he and his colleagues have found from studying California homes. One of the concerns in their research for the California Energy Commission was homeowners changing out 1″ thick standard fiberglass filters with 1″ thick pleated filters. The Air Conditioning Contractors of America (ACCA) protocols for HVAC design assume a pressure drop of 0.10 inches of water column (i.w.c.) across the filter. (Keep that number, 0.1 i.w.c., in mind as a reference point. I will be coming back to it.) If a system is designed with a standard filter for that pressure drop, the pressure drop with a pleated filter of the same size will most likely be higher. In addition, poorly designed and installed duct systems already have external static pressures that are too high. The typical furnace or air handler is rated for 0.5 i.w.c. but many run much higher pressure. David Richardson of the National Comfort Institute says that in the testing they've done, the average system is running at about 0.82 i.w.c. Result: In the California study, Proctor et al. found that the pressure drop across the filter in 34 HVAC systems was 0.28 i.w.c. That's nearly three times what ACCA protocols assume. It's also more than half of the rated external static pressure for the whole system. Article: Is There a Downside to High-MERV Filters? by David Springer, Home Energy Magazine, 2 November 2009 David Springer of the Davis Energy Group published this great article with a lot of detail about what they did and what they found, including blower energy use, compressor energy use, and the specific filters they tested. I will let you go there for the details because here I am mainly going to focus on the issue of pressure drop across the filter and the resulting effect on air flow. And speaking of filter pressure drop, here's their chart for filters with MERV ratings from 2 to 13. They tested all the filters at the same width and height (16″ x 25″) but the depth varied from 1″ to 4″. They used 492 feet per minute (fpm) as the face velocity because that's what the ASHRAE filter standard (52.2) calls for. With that face velocity and those dimensions, the air flow rate is 1,367 cubic feet per minute (cfm). (Flow rate equals area times velocity; see my article on the continuity equation for more on this.) Results: As you can see, there's not a steady increase in pressure drop as the MERV rating increases. What does happen, though, is that the pressure drop jumps up significantly as soon as you change from the standard 1″ fiberglass filter (MERV-2) to the next level at MERV-6. They also found "a definite trend toward lower air flow with higher-MERV filters for systems using PSC motors." (PSC stands for "permanent split capacitor." A PSC motor is the one powering most HVAC blowers. Variable speed blowers have electronically commutated motors, ECMs.) The final result I will mention here is that they did not see as much difference as they expected for filters of different depths. For example, "the 4-inch Filtrete 1550 (MERV 12) was only marginally better than the 1-inch Filtrete 1700 (also MERV 12) and the two other [1-inch] MERV 11 filters of the same brand (1000 and 1085)." Article: The Effects of Filtration on Pressure Drop and Energy Consumption in Residential HVAC Systems (pdf) by Brent Stephens, Atila Novoselac, PhD, and Jeffrey A. Siegel, PhD, HVAC&R Research, Vol. 16, #3, May 2010 This one is an academic paper so if you want all the details, equations, and references to other works, click the link above and download the paper. (Brent was a student at the time he wrote this paper and has a page on his filter research on his website at the Illinois Institute of Technology, if you want to dive even deeper.) They looked at filter pressure drop and energy consumption, both theoretically and using four months of data from two air conditioning systems in a test house in Austin, Texas. Results: What they found is what you would expect, and in their limited range of MERV ratings tested, they did see an increase with each step up the MERV scale. Here are their results for filter pressure drop: So the low-MERV filter is hitting the ACCA design pressure drop. The mid-MERV is twice as much and the high-MERV is three times as much. They also found that air flow in the high-MERV filters dropped by 7% and 11% in the two HVAC systems compared to the low-MERV filters. Likewise, the mid-MERV filters also showed decreased air flow relative to the low-MERV fitlers, this time 3% and 8% lower in the two systems. As you can see above, the research shows that in general, HVAC systems with high-MERV filters* have a higher pressure drop across the filter. This part is common to all three studies above. What happens with the air flow depends on what kind of blower the HVAC system uses. In a system with a PSC blower, the air flow drops and energy use does not change much. The Stephens paper cites a 2002 study showing that 90% of all residential HVAC systems had PSC blowers. Certainly that number has fallen in the past 16 years, as high-performance homes and high-performance HVAC systems have become more popular. But I am sure the great majority of homes still have PSC motors running the blower. For those with the other type, the electronically commutated motor (ECM), the controls on those motors typically ramp up the motor speed as the pressure increases so relatively constant air flow is maintained. But there's a penalty. Blowers with ECMs can be more efficient than those with PSC motors when they are operating against the pressure they are designed for. But when the pressure is higher, they can end up using more energy than the PSC blower. So what can you do to be able to use a high-MERV filter* and not suffer a high pressure drop across the filter and the resulting loss of air flow (PSC blower) or increased energy use (ECM blower)? It's actually pretty simple. You just have to make the filter large enough to have a low face velocity. And that's where I am going next with this series. You can get a head start by reviewing the other articles I've written on this topic in the past few months, especially the one on the continuity equation.
