41Continuous variable valve timing — offers a unique ability to have independent control of the intake and exhaust valves in an internal combustion engine. For any engine load criteria, the timing of intake and exhaust can be independently programmed [1]. The main variations of… …
42Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… …
43Not-To-Exceed — The Not To Exceed (NTE) standard recently promulgated by the United States Environmental Protection Agency (EPA) ensures that heavy duty engine emissions are controlled over the full range of speed and load combinations commonly experienced in… …
44Network performance — refers to the service quality of a telecommunications product as seen by the customer. It should not be seen merely as an attempt to get more through the network. The following list gives examples of Network Performance measures for a circuit… …
45Brushless DC electric motor — A microprocessor controlled BLDC motor powering a micro remote controlled airplane. This external rotor motor weighs 5 grams, consumes approximately 11 watts (15 millihorsepower) and produces thrust of more than twice the weight of the plane …
46Variable valve timing — Variable valve timing, or VVT, is a generic term for an automobile piston engine technology. VVT allows the lift or duration or timing (some or all) of the intake or exhaust valves (or both) to be changed while the engine is in operation. Two… …
47Lean burn — refers to the use of lean mixtures in an internal combustion engine. The air fuel ratios can be as high as 65:1, so the mixture has considerably less fuel in comparison to the stoichiometric combustion ratio (14.7:1 for petrol for example).… …
48Data Vault Modeling — is a database modeling method that is designed to provide historical storage of data coming in from multiple operational systems. It is also a method of looking at historical data that, apart from the modeling aspect, deals with issues such as… …
49Not-To-Exceed (NTE) — This article deals with an emissions standard for Heavy Duty Diesel Engines which was created by the United States Environmental Protection Agency. The Not To Exceed (NTE) standard recently promulgated by the United States Environmental… …
5080 PLUS — is an initiative to promote more electrical energy efficient computer power supply units (PSU). It certifies products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100%… …
