IlluminanceIn photometry, illuminance is the total luminous flux incident on a surface, per unit area. It is a measure of how much the incident light illuminates the surface, wavelength-weighted by the luminosity function to correlate with human brightness perception. Similarly, luminous emittance is the luminous flux per unit area emitted from a surface. Luminous emittance is also known as luminous exitance. In SI units illuminance is measured in lux (lx), or equivalently in lumens per square metre (lm·m−2).
Optimizing compilerIn computing, an optimizing compiler is a compiler that tries to minimize or maximize some attributes of an executable computer program. Common requirements are to minimize a program's execution time, memory footprint, storage size, and power consumption (the last three being popular for portable computers). Compiler optimization is generally implemented using a sequence of optimizing transformations, algorithms which take a program and transform it to produce a semantically equivalent output program that uses fewer resources or executes faster.
Workplace aggressionWorkplace aggression is a specific type of aggression which occurs in the workplace. Workplace aggression is any type of hostile behavior that occurs in the workplace. It can range from verbal insults and threats to physical violence, and it can occur between coworkers, supervisors, and subordinates. Common examples of workplace aggression include gossiping, bullying, intimidation, sabotage, sexual harassment, and physical violence. These behaviors can have serious consequences, including reduced productivity, increased stress, and decreased morale.
Film speedFilm speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system introduced in the mid-1970s. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Prior to ISO gaining traction the best known systems were ASA in the U.S. and DIN in Europe. The term speed comes from the early days of photography.
Simple eye in invertebratesA simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive.
Workplace harassmentWorkplace harassment is the belittling or threatening behavior directed at an individual worker or a group of workers. Recently, matters of workplace harassment have gained interest among practitioners and researchers as it is becoming one of the most sensitive areas of effective workplace management, because a significant source of work stress is associated with aggressive behaviors at workplace. In Asian countries, workplace harassment is one of the poorly attended issues by managers in organizations.
Heat illnessHeat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion. It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. It can affect any or all anatomical systems. Heat illnesses include: Heat stroke, heat exhaustion, heat syncope, heat edema, heat cramps, heat rash, heat tetany.
