Power Amplifier Classes
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier's characteristics and performance. The classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a signal waveform applied to the input. A class A amplifier is conducting through all the period of the signal; Class B only for one-half the input period, class C for much less than half the input period. A Class D amplifier operates its output device in a switching manner; the fraction of the time that the device is conducting is adjusted so a pulse-width modulation output is obtained from the stage. Additional letter classes are defined for special-purpose amplifiers, with additional active elements or particular power supply improvements; sometimes a new letter symbol is used by a manufacturer to promote its proprietary design.

Carbon Star
A carbon star (C-type star) is typically an asymptotic giant branch star, a luminous red giant, whose atmosphere contains more carbon than oxygen. The two elements combine in the upper layers of the star, forming carbon monoxide, which consumes most of the oxygen in the atmosphere, leaving carbon atoms free to form other carbon compounds, giving the star a "sooty" atmosphere and a strikingly ruby red appearance. There are also some dwarf and supergiant carbon stars, with the more common giant stars sometimes being called classical carbon stars to distinguish them. In most stars (such as the Sun), the atmosphere is richer in oxygen than carbon. Ordinary stars not exhibiting the characteristics of carbon stars but cool enough to form carbon monoxide are therefore called oxygen-rich stars. Carbon stars have quite distinctive spectral characteristics, and they were first recognized by their spectra by Angelo Secchi in the 1860s, a pioneering time in astronomical spectroscopy.

Class C Drug
These drugs are known in the UK as ''controlled drugs'', because this is the term by which the act itself refers to them. In more general terms, however, many of these drugs are also controlled by the Medicines Act 1968, there are many other drugs which are controlled by the Medicines Act but not by the Misuse of Drugs Act, and some other drugs (alcohol, for example) are controlled by other laws. The Misuse of Drugs Act sets out three separate categories, Class A, Class B, and Class C. Class A drugs represent those deemed most dangerous, and so carry the harshest punishments. Class C represents those thought to have the least capacity for harm, and so the Act demands more lenient punishment. In reality the potential harm has little bearing on the class, which has led to dissatisfaction with drug laws. Being found in possession of a drug on this list is dealt with less seriously than would be if it were deemed that there is intent to supply (even without payment) the drug to ot ...

Classful Network
A classful network is an obsolete network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. The method divides the IP address space for Internet Protocol version 4 (IPv4) into five address classes based on the leading four address bits. Classes A, B, and C provide unicast addresses for networks of three different network sizes. Class D is for multicast networking and the class E address range is reserved for future or experimental purposes. Since its discontinuation, remnants of classful network concepts have remained in practice only in limited scope in the default configuration parameters of some network software and hardware components, most notably in the default configuration of subnet masks. Background In the original address definition, the most significant eight bits of the 32-bit IPv4 address was the ''network number'' field which specified the particular network a host was attached to.

Airspace Class
The world's navigable airspace is divided into three-dimensional segments, each of which is assigned to a specific class. Most nations adhere to the classification specified by the International Civil Aviation Organization (ICAO) and described below, though they might use only some of the classes defined below, and significantly alter the exact rules and requirements. Similarly, individual nations may also designate special use airspace (SUA) with further rules for reasons of national security or safety. Abbreviations used in this article ICAO definitions On March 12, 1990, ICAO adopted the current airspace classification scheme. The classes are fundamentally defined in terms of flight rules and interactions between aircraft and air traffic control (ATC). Generally speaking, the ICAO airspaces allocate the responsibility for avoiding other aircraft, namely either to ATC (if separation is provided) or to the aircraft commander (if not). Some key concepts are: * Separation: Mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driver's License In The United States
In the United States, driver's licenses are issued by each individual state, territory, and the District of Columbia rather than by the federal government due to federalism. Drivers are normally required to obtain a license from their state of residence and all states recognize each other's licenses for non-resident age requirements. There are also licenses for motorcycle use. Generally, a minimum age of 16 is required to obtain a driver's or motorcycle license, and 18 for a commercial driver's license which is required for operating heavy size vehicles ( buses, trucks, tractor-trailers) or vehicles with at least 16 passengers or hazardous materials. A state may also suspend an individual's driving privilege within its borders for traffic violations. Many states share a common system of license classes, with some exceptions, e.g. commercial license classes are standardized by federal regulation at . Many driving permits and ID cards display small digits next to each data field. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driving Licence In The United Kingdom
In the United Kingdom, a driving licence is the official document which authorises its holder to operate motor vehicles on highways and other public roads. It is administered in England, Scotland and Wales by the Driver and Vehicle Licensing Agency (DVLA) and in Northern Ireland by the Driver & Vehicle Agency (DVA). A driving licence is required in England, Scotland, and Wales for any person (except the sovereign) driving a vehicle on any highway or other "road", as defined in s.192 Road Traffic Act 1988, irrespective of the ownership of the land over which the road passes. Similar requirements apply in Northern Ireland under the Road Traffic (Northern Ireland) Order 1981. Prior to the UK leaving the European Union on 31 January 2020 and during the transition period which ended on 31 December 2020, a UK driving licence was a European driving licence, adhering to Directive 2006/126/EC and valid throughout the European Economic Area.

List Of North American Broadcast Station Classes
This is a list of broadcast station classes applicable in much of North America under international agreements between the United States, Canada and Mexico. Effective radiated power (ERP) and height above average terrain (HAAT) are listed unless otherwise noted. All radio and television stations within of the US-Canada or US-Mexico border must get approval by both the domestic and foreign agency. These agencies are Industry Canada/Canadian Radio-television and Telecommunications Commission (CRTC) in Canada, the Federal Communications Commission (FCC) in the US, and the Federal Telecommunications Institute (IFT) in Mexico. AM Station class descriptions All domestic (United States) AM stations are classified as A, B, C, or D. * A (formerly I) — clear-channel stations — 10 kW to 50 kW, 24 hours. **Class A stations are only protected within a radius of the transmitter site. **The old Class I was divided into three: Class I-A, I-B and I-N.

Smooth Function
In mathematical analysis, the smoothness of a function (mathematics), function is a property measured by the number of Continuous function, continuous Derivative (mathematics), derivatives it has over some domain, called ''differentiability class''. At the very minimum, a function could be considered smooth if it is differentiable everywhere (hence continuous). At the other end, it might also possess derivatives of all Order of derivation, orders in its Domain of a function, domain, in which case it is said to be infinitely differentiable and referred to as a C-infinity function (or C^ function). Differentiability classes Differentiability class is a classification of functions according to the properties of their derivatives. It is a measure of the highest order of derivative that exists and is continuous for a function. Consider an open set U on the real line and a function f defined on U with real values. Let ''k'' be a non-negative integer. The function f is said to be of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recreational Vehicle
A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. Types of RVs include motorhomes, campervans, coaches, caravans (also known as travel trailers and camper trailers), fifth-wheel trailers, popup campers, and truck campers. Features Typical amenities of an RV include a kitchen, a bathroom, and one or more sleeping facilities. RVs can range from utilitarian – containing only sleeping quarters and basic cooking facilities – to luxurious, with features like air conditioning (AC), water heaters, televisions and satellite receivers, and quartz countertops, for example. RVs can either be trailers (which are towed behind motor vehicles) or self-propelled vehicles. Most RVs are single-deck; however, double-deck RVs also exist. To allow a more compact size while in transit, larger RVs often have expandable sides (called slide-outs) or canopies that are deployed when stationary. History T ...
