PRINCIPLE slowly started gaining traction in the global sustainable energy generation realm. It was earlier believed to be a To understand the working principle of TPVs, let us break flawed method whose energy conversion efficiency was not down the term into three parts: Thermo (meaning Heat), high enough for commercial use. However, in recent times, Photo (meaning Light) and Voltaic (meaning Electricity research has picked up, addressing the need of increasing produced by chemical action). Thus, a Thermophotovoltaic the energy conversion efficiency while making it system uses light to heat up a thermal emitter, which in economically viable for commercial applications. This paper turn emits radiation (Infrared) on a photovoltaic (PV) will throw light on the various advancements in the field of diode to produce electricity. Conventional photovoltaics TPV systems and investigate the potential avenues where exploit only the visible band of solar rays for electricity TPVs may be used in the future. We will also be looking at generation. The visible band contains less than half the the history of development of TPVs so that we may be aware total radiation of solar energy. -
Photonic Lantern Illumination Source
PLIS (Photonic Lantern Illumination Source): an efficient light source for light sheet microscopy Jordi Andilla1, Rodrigo Becerra1,2, Gustavo Castro1, Pablo Loza-Alvarez1 1ICFO, The Institute of Photonic Sciences Mediterranean Technology Park, Av. Carl Friedrich Gauss, num. 3 08860 Castelldefels (Barcelona), Spain 2INAOE, Instituto Nacional de Astrofísica, Optica y Electrónica Luis Enrique Erro No. 1, Puebla, 72840, México E-mail: [email protected], [email protected] KEY WORDS: Light sheet fluorescence microscopy, Scattering Imaging, Photonic Lantern. 1. MOTIVATION Fluorescence Microscopy has been crucial in the modern understanding of biological molecular processes. More specifically, techniques like laser scanning confocal microscopy or light sheet microscopy [1] provided high resolution up to the diffraction limit. These last techniques have been possible thanks to the good emitting properties of lasers. However, for many high-resolution microscopy applications some of the characteristics of lasers are not needed or even produce undesired effects. The narrow wavelength bandwidth is not needed in the fluorescence microscopy due to the wide spectral excitation band of the fluorophores. In fact, LED sources and super-continuum lasers result in a more gentle excitation of the fluorescence and therefore in the production of high S/N images. Furthermore, in certain techniques, based on elastic scattering imaging, TIRF or light-sheet microscopy, the temporal coherence of the lasers is not only not required but also it produces undesired interference patterns or structures that affect the image quality. On the other hand, for all those imaging techniques, spatial coherence is a strong requirement to obtain the diffraction-limited illumination necessary for obtaining high-resolution images. -
Basic Principles and Techniques of Lighting
Lighting 102 Basic Principles and Techniques of Lighting by John J. Rankin VINCENTLIGHTING.COM 1 /" -Ê"Ê-/ Ê/ The following criteria should be used to determine if stage lighting is necessary and effective. £°Ê 6- /9 Visibility is a very important function of stage lighting. The audience should be able to see exactly what you want them to see, or not see those things that should remain hidden. Therefore, we might rename this function as “selective visibility.” An example of selective visibility can be found in the play, Wait Until Dark by Frederick Knott. A blind woman is terrorized by a murderer hiding in her apartment. To even her odds against him, she smashes all of the light bulbs thus plunging him - and the audience - into darkness. The action is revealed verbally and occasionally visually with flashlights, matches, and a very surprising source of light at the climax of the play. Ó°Ê , 6 /" Ê"Ê", Similar to selective visibility, revealing the form of the actor, dancer, or speaker will make them stand out from their background. Using techniques described later in this article, you will be able to make the subject appear natural and be the focus of attention for the viewers. For example, when lighting a ballet it is important for the stage lighting to reveal the form of the dancers. The audience wishes to see the dancers move through the space and stand apart from the background. Lighting ballet has been described as “lighting fish in an aquarium.” Light is the same as water in this metaphor. -

The Magic Lantern Gazette Volume 24, Number 4 Winter 2012
ISSN 1059-1249 The Magic Lantern Gazette Volume 24, Number 4 Winter 2012 The Magic Lantern Society of the United States and Canada www.magiclanternsociety.org The Editor’s Page 2 Winter Dissolving Views What a queer, pretty picture it is that greets me, as I turn my back to the rushing flakes, and so get my eyes open to look at it. Be- yond a wide swale, that yesterday was gold and green but now is glistening wintry white, rises a small eminence, where a dissolving view of trees and buildings is momentarily formed, then hidden, then brought out again, mirage-like, in the most curi- ous and dreamlike unreality, yet always with singular beauty. Gray is the only color, a soft, purplish, silvery gray; and the silhou- ette is the only style of drawing. By their outlines I guess that the wavering slender spike amid the glistening haze is the church steeple—that squarish blur the belfry of the court-house—the next irregular smudge a certain collection of house-roofs; but all seem as foreign and unsubstantial as shadows, so quaintly are they now clouded, now lightly revealed by the swirling, satiny snowflakes that fill the air with particle luminous in themselves yet obscuring the landscape.

Lights and Lasers May Be Used As a Visual Effect
PURPOSE 1 Stage lighting has multiple functions, including: • Selective visibility: The ability to see what is occurring on stage. Any lighting design will be ineffective if the viewers cannot see the characters, unless this is the explicit intent. • Revelation of form: Altering the perception of shapes onstage, particularly three- dimensional stage elements. • Focus: Directing the audience's attention to an area of the stage or distracting them from another. • Mood: Setting the tone of a scene. Harsh red light has a different effect than soft lavender light. • Location and time of day: Establishing or altering position in time and space. Blues can suggest night time while orange and red can suggest a sunrise or sunset. Use of mechanical filters ("gobos") to project sky scenes, the Moon, etc. • Projection/stage elements: Lighting may be used to project scenery or to act as scenery onstage. • Plot (script): A lighting event may trigger or advance the action onstage and off. • Composition: Lighting may be used to show only the areas of the stage which the designer wants the audience to see, and to "paint a picture".[4][5] • Effect: In pop and rock concerts or DJ shows or raves, colored lights and lasers may be used as a visual effect. Lighting design is an art form, and thus no one way is the "correct" way. There is a modern movement that states that the lighting design helps to create the environment in which the action takes place while supporting the style of the piece. "Mood" is arguable while the environment is essential. 1) Selective visiblity: The #1 function of light is to see, to illuminate, to make visible to the nake human eye. -
2020 Lantern Creation Guide
LANTERN CREATION GUIDE for the Napa Lantern Parade We are so excited for the Napa Lantern Parade and hope you are too! This instructional guide exists to provide ideas, inspirations, and answer FAQs about lantern creation. Anyone and everyone is welcome to participate in the parade regardless of skill level, access to materials, or time needed to make a lantern. Any additional questions please contact Mered ith at [email protected] 707-257-9953 WHAT IS A LANTERN? A lantern generally refers to any form of portable lighting, where a transparnet or translucent casing allows a light from inside its walls shine through. They are most often suspended or carried, but can also be worn! Lanterns have important roles in a variety of cultural and historical traditions, and have also evolved into their own modern art form in recent decades. Community lantern parades are popular in many cities around the world. LANTERN PARADE OVERVIEW WH AT The Lantern Parade welcomes community members from all walks of life to play with light and collectively illuminate the night! The parade of participants showing off hundreds of lanterns will weave throughout downtown Napa on an approximate one -mile loop, energized by live music, and other lighted art installations along the way. This parade is part of the Napa Lighted Arts Festival which will feature nearly a dozen lighted art installations in downtown Napa, including projection mapping, interactive lighted sculptures, and more. WH EN January 1 7th, 2020 Parade will depart from Veteran's Park at 6:30pm. We estimate the parade to last about 45 min to one hour. -
Petromax 834 Renovation
Petromax 834 renovation As I have restored a reasonable number of Petromax model 834/835 do nut lamps, I want to share my experiences with the reader. The differences between models 834 and 835 are mainly a matter of size, so my observations apply equally to both. If this is not the case I have made separate notes. There are of course other models that are more or less similar as for instance the Px 790, a 834 with copper tank. But I leave it up to the reader to match the details on his or her lamp model. The numbers of the parts and in the text refer to the component drawing. In principle these lamps function In much the same way as any other pressure lamp such as for example the Petromax 500 cp model 829. Important: These lamps are kerosene / paraffin lamps; using them with any other fuel is dangerous! Main parts of the lamp The Petromax donut lamps consist of primary and secondary groups of parts: • Fuel tank o Pressure gauge o Pump o Air / filling cap • Fuel system (97) o Tank o (Main) fuel tube with valve o Generator spiral with filter o Vaporizer • Mixing chamber (95) o Flow regulation o Burner head • Pre heater ring (9) o Ignition • Main chassis • Sub chassis 1 - 21 Copyright 2004 - W.J. van der Velden Fuel tank The fuel tank is made of galvanized steel with three support legs, an air pump, fuel pipe connection, a pressure gauge and filler cap. To check the integrity of the tank I advise the removal of the old paint. -

2009 ALA/AIA Library Buildings Awards Arabian Library, Scottsdale Public Library, Scottsdale, Arizona richard+bauer architecture, LLC The 20,000-square-foot library is a freestanding replacement for the small, shared use facility at the Desert Arroyo Middle School. Walls of weathered steel plate reflect the terra-cotta walls of stone as they cant overhead. The interior of the cavernous reading room is clad in an acoustically absorbent perforated wood treatment that provides noise mitigation, allowing for spaces that enable patrons to enjoy reading, studying, and small group activities without excessive noise spillover from adjacent zones. The accessible floor provides recessed mechanical, electrical, and data distribution for long term flexibility and ease of maintenance. C.V. Starr East Asian Library, University of California Berkeley Tod Williams Billie Tsien Architects The building was conceived as a strong symmetrical box, a repository for character language texts and a sanctuary for study. The mass of the 4-story building is embedded in Berkeley’s hilly landscape and thus experienced in a dynamic way. To increase the building’s energy performance, perforated metal screens were installed behind the bronze grilles preventing 45% of direct sunlight from entering the building and favorably reducing the library’s cooling loads. Other efforts to reduce the building’s impact on the environment included the use of occupancy sensors, Bamboo flooring, native plantings in the landscape and storm water recharge basins. Chongqing Library, Chongqing, China Perkins Eastman The 490,500-square-foot new Chongqing Library is a stunning urban complex, which respects the long and unique culture of its predecessor while looking toward this energetic region’s future by projecting a modern image. -
