Light-dependent reactions of photosynthesis at the thylakoid membrane. Light-dependent reactions are certain photochemical reactions involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions: the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI).
The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle [1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many ...

The main difference is that instead of finding the most likely model, these techniques omit the models, which are not compatible with data. [3] [4] The example shown in the figure on the right illustrates a model-based FDI technique for an aircraft elevator reactive controller through the use of a truth table and a state chart.
Most Cherenkov detectors aim at recording the Cherenkov light produced by a primary charged particle. Some sensor technologies explicitly aim at Cherenkov light produced (also) by secondary particles, be it incoherent emission as occurring in an electromagnetic particle shower or by coherent emission, for example Askaryan effect.
A pedestrian detection system. Sensors can be used to detect pedestrians, objects, or both in a driver's blind spots. [52] Pedestrian detection systems are proximity sensors that detect objects and pedestrians from up to several meters away from the forklift. Ultrasonic sensors are proximity sensors typically used in the rear of the forklift.
The Great Oil Sniffer Hoax was a 1979 scandal involving French oil company Elf Aquitaine. The company spent millions of dollars developing a new gravity wave-based oil detection system, which was later revealed to be a scam. Elf lost over $150 million in the hoax. In France, the scandal is known as the "Avions Renifleurs" ("Sniffer Planes"). [1]
By utilizing the interaction picture, one can use time-dependent perturbation theory to find the effect of H 1,I, [15]: 355ff e.g., in the derivation of Fermi's golden rule, [15]: 359–363 or the Dyson series [15]: 355–357 in quantum field theory: in 1947, Shin'ichirÅ Tomonaga and Julian Schwinger appreciated that covariant perturbation ...
