The development of optoelectronic devices requires breakthroughs in new material systems and novel device mechanisms, and the demand recently changes from the detection of signal intensity and responsivity to the exploration of sensitivity of polarized state information.

14 Patterns of Biophilic Design

LED stands for light emitting diode. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink. The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting CFL.

Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye. The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches , which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things. Historically, another important source of light for humans has been fire , from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems , electric lighting has effectively replaced firelight.

In longitudinal waves , the vibrations are parallel to the direction of wave travel. Examples of longitudinal waves include:. Longitudinal waves show areas of compression and rarefaction :. In the diagram, the compressions move from left to right and energy is transferred from left to right. However, none of the particles are transported along a longitudinal wave. Instead, they move backwards and forwards between compressions as the wave is transmitted through the medium.

Biophilic design can reduce stress, enhance creativity and clarity of thought, improve our well-being and expedite healing; as the world population continues to urbanize, these qualities are ever more important. Theorists, research scientists, and design practitioners have been working for decades to define aspects of nature that most impact our satisfaction with the built environment. Biophilia in Context looks at the evolution of biophilic design in architecture and planning and presents a framework for relating the human biological science and nature. Design Considerations explores a sampling of factors e. The Patterns lays out a series of tools for understanding design opportunities, including the roots of the science behind each pattern, then metrics, strategies and considerations for how to use each pattern. This paper moves from research on biophilic responses to design application as a way to effectively enhance health and well-being for individuals and society.

Light , electromagnetic radiation that can be detected by the human eye. Within that broad spectrum the wavelengths visible to humans occupy a very narrow band, from about nanometres nm; billionths of a metre for red light down to about nm for violet light. The spectral regions adjacent to the visible band are often referred to as light also, infrared at the one end and ultraviolet at the other. The speed of light in a vacuum is a fundamental physical constant , the currently accepted value of which is exactly ,, metres per second, or about , miles per second. The physicist is interested in the physical properties of light, the artist in an aesthetic appreciation of the visual world.

Мидж от неожиданности стукнулась головой о стекло. Бринкерхофф опрокинул директорский стул и бросился к двери. Он сразу же узнал этот голос. - Директор! - воскликнул он и, подойдя к Фонтейну, протянул руку.  - С возвращением, сэр.

Со временем Танкадо прочитал о Пёрл-Харборе и военных преступлениях японцев. Ненависть к Америке постепенно стихала. Он стал истовым буддистом и забыл детские клятвы о мести; умение прощать было единственным путем, ведущим к просветлению. К двадцати годам Энсей Танкадо стал своего рода культовой фигурой, представителем программистского андеграунда.

Дэвид исчез. Значит, приснилось, подумала Сьюзан и села в кровати. Комната в викторианском стиле, сплошь кружева и антиквариат - лучший гостиничный номер в Стоун-Мэнор.

Окно местоположения Следопыта откликнулось именно так, как он рассчитывал. ОТОЗВАТЬ СЛЕДОПЫТА. Он быстро нажал Да. ВЫ УВЕРЕНЫ. Он снова ответил Да.

У нас очень строгие правила относительно контактов клиента и сопровождающего. - Но… - Вы спутали нас с кем-то другим. У нас всего две рыженькие, Иммакулада и Росио, и ни та ни другая не станут ни с кем спать за деньги. Потому что это проституция, а она в Испании строжайше запрещена. Доброй ночи, сэр. - Но… Послышался щелчок положенной на рычаг трубки. Беккер беззвучно выругался и повесил трубку.

Капля Росы. Он слышал приятный голос сеньора Ролдана из агентства сопровождения Белена. У нас только две рыжеволосые… Две рыжеволосые, Иммакулада и Росио… Росио… Росио… Беккер остановился как вкопанный. А еще считаюсь лингвистом. Он не мог понять, как до него не дошло .

 - Нам нужно установить разницу между этими элементами.  - Он повернулся к бригаде своих помощников.  - Кто знает, какая разница между этими элементами. На лицах тех застыло недоумение.

Проклиная судьбу, он вылез из автобуса. К клубу вела узкая аллея. Как только он оказался там, его сразу же увлек за собой поток молодых людей. - А ну с дороги, пидор! - Некое существо с прической, больше всего напоминающей подушечку для иголок, прошествовало мимо, толкнув Беккера в бок.

In the seventeenth century two rival theories of the nature of light were proposed, the wave theory and the corpuscular theory.
