Child pornography is illegal in most countries, but there is substantial variation in definitions, categories, penalties, and interpretations of laws. Differences include the definition of "child" under the laws, which can vary with the age of sexual consent; the definition of "child pornography" itself, for example on the basis of medium or degree of reality; and which actions are criminal (e ...
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
Color-coding: hydrophobicity from microenvironment in folded proteins [10] The classical table/wheel of the standard genetic code is arbitrarily organized based on codon position 1. Saier, [ 11 ] following observations from, [ 12 ] showed that reorganizing the wheel based instead on codon position 2 (and reordering from UCAG to UCGA) better ...
Electronic components have a wide range of failure modes. These can be classified in various ways, such as by time or cause. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes. In semiconductor devices, problems in the device package may cause ...
IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against ...
Once a DC operating point is defined by the DC load line, an AC load line can be drawn through the Q point. The AC load line is a straight line with a slope equal to the AC impedance facing the nonlinear device, which is in general different from the DC resistance. The ratio of AC voltage to current in the device is defined by this line.
IEEE 200-1975 or "Standard Reference Designations for Electrical and Electronics Parts and Equipments" is a standard that was used to define referencing naming systems for collections of electronic equipment. IEEE 200 was ratified in 1975. The IEEE renewed the standard in the 1990s, but withdrew it from active support shortly thereafter.
Consider a direct-current circuit with a nine-volt DC source; three resistors of 67 ohms, 100 ohms, and 470 ohms; and a light bulb—all connected in series. The DC source, the conductors (wires), the resistors, and the light bulb (the load) all have resistance; all use and dissipate supplied energy to some degree. Their physical ...
