AUCTIONS AND E-COMMERCE |
|
An auction is the process of buying and selling things by offering them up for bid, taking bids, and then selling the item to the highest bidder. Auctioning can be traced as far back as 500 B.C.[1] In economic theory, an auction is a method for determining the value of a commodity that has an undetermined or variable price. Auctions can be with reserve or minimum, or without minimums, or absolute or no reserve. In reserve auctions, there is a minimum bid or reserve price; if the bidding does not reach the minimum, there is no sale (but the person who puts the item up for auction may still owe a fee to the auctioneer or auction company). In absolute or no reserve auctions, the sale is guaranteed, with only the price left to be determined. In the context of auctions, a bid is an offered price.

CAMERAS / CAMERA TESTING |
|
A camera is a device used to take pictures (usually photographs), either singly or in sequence, with or without sound recording, such as with video cameras. A camera that takes pictures singly is sometimes called a photo camera to distinguish it from a video camera. The name is derived from camera obscura, Latin for "dark chamber", an early mechanism for projecting images in which an entire room functioned much as the internal workings of a modern photographic camera, except there was no way at this time to record the image short of manually tracing it. Cameras may work with the visual spectrum or other portions of the electromagnetic spectrum.

CHEMISTRY |
|
Chemistry (derived from alchemy) is the science of matter at or near the atomic scale. In this pursuit chemistry deals with the properties of such matter, the tranformations of matter and the interactions of matter with other matter and with energy.
|
ELECTRONICS |
|
The field of electronics is the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the field of electronics engineering, and includes the hardware design side of computer engineering.
|
ENERGY |
|
Energy is the ability to do work. It may express itself in different forms; kinetic and potential energy and the ability to do mechanical work; thermal, chemical and electromagnetic energy; nuclear energy, and various other forms. Power is the time rated expenditure of energy.
|
ENGINEERING - ELECTRICAL |
|
Electrical engineering (sometimes referred to as electrical and electronics engineering) is a professional engineering discipline that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century with the commercialization of the electric telegraph and electrical power supply. The field now covers a range of sub-disciplines including those that deal with power, control systems, electronics and telecommunications.
|
ENGINEERING - GENERAL |
|
Engineering is the application of scientific and technical knowledge to solve human problems. Engineers use imagination, judgement and reasoning to apply science, technology, mathematics, and practical experience. The result is the design, production, and operation of useful objects or processes.
|
FIBER OPTICS |
|
An optical fiber (or fibre) is a transparent thin fiber, usually made of glass or plastic, for transmitting light. Fiber optics is the branch of science and engineering concerned with such optical fibers.
Optical fibers are commonly used in telecommunication systems, as well as in illumination, sensors, and imaging optics.
|
FORENSIC COMPUTERS |
|
Computer forensics is application of the scientific method to digital media in order to establish factual information for judicial review. This process often involves investigating computer systems to determine whether they are or have been used for illegal or unauthorized activities. Mostly, computer forensics experts investigate data storage devices, either fixed like hard disks or removable like compact disks and solid state devices.

INDUCTION HEATING |
|
Induction heating is the process of heating a metal object by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal. An induction heater (for any process) consists of an electromagnet, through which a high-frequency AC is passed. Heat may also be generated by magnetic hysteresis losses.
|
MICROWAVE HEATING |
|
A microwave oven, or microwave, is a kitchen appliance employing microwave radiation primarily to cook or heat food. Microwave ovens have revolutionized cooking since their use became widespread in the 1970s.
|
TELECOMMUNICATIONS |
|
Telecommunications is the communication of information over a distance. The term is most used to refer to communication using some type of signalling, such as the aldis lamp or the transmission and reception of electromagnetic energy. This covers many media and technologies including radio, fiber optics, telegraphy, television, telephone, data communication and computer networking, although other types of signalling are also included (see Telecommunications History and especially Early Telecommunications).

WELL LOG INTERPRETATION |
|
Well logging is a technique used in the oil and gas industry for recording rock and fluid properties to find hydrocarbon zones in the geological formations below the Earths crust. A logging procedure consists of lowering a logging tool on the end of a wireline into an oil well (or hole) to measure the rock and fluid properties of the formation. An interpretation of these measurements is then made to locate and quantify potential depth zones containing oil and gas (hydrocarbons). Logging tools developed over the years measure the electrical, acoustic, radioactive, electromagnetic, and other properties of the rocks and their contained fluids. Logging is usually performed as the logging tools are pulled out of the hole. This data is recorded to a printed record called a Well Log and is normally transmitted digitally to office locations. Well logging is performed at various intervals during the drilling of the well and when the total depth is drilled, which could range in depths from 300 m to 8000 m (1000 ft to 25,000 ft) or more.
