Ramp metering is an effective, viable, and practical strategy used to manage freeway traffic. It is a proven freeway management technique as various forms of ramp control have been in place since the 1960s in the Chicago, Detroit, and Los Angeles areas. Due in part to the success of these early applications, ramp metering has received increased emphasis in recent years under the umbrella of adv...

A rationale is offered and methodology illustrated for integrating the fundamental steps involved in the collection and processing of blood for laboratory evaluation. The approach taken in the development of these concepts and components greatly extends the possibilities of laboratory systems integration without upsetting established modalities. A prototype design of the integrated blood-collec...

The issues of research work seed metering devices by the method discrete elements (DEM) are considered. A 3d-model developed intended for use with an unmanned aerial vehicle is presented. Its main design parameters and characteristics virtual stand used in study described. brief description physical model interaction seeds working given. As a result study, data were obtained on capacity hopper ...

Sandy water sources are widely distributed and important for agricultural development. However, no explicit result has been achieved in the research of accuracy reliability pipeline metering devices as well flow rate measurement objects (water or water–sand) different process pipelines conveying muddy water. In this study, seven kinds sediment concentration gradients, C0–C6 (0.2–7.19%), three v...

A metering scheme is a method by which an audit agency is able to measure the interaction between servers and clients during a certain number of time frames. Naor and Pinkas 21] proposed metering schemes where any server is able to compute a proof, i.e., a value to be shown to the audit agency at the end of each time frame, if and only if it has been visited by a number of clients larger than o...

Metering technology is one of the core technologies of the smart power grid. The overall metering solution and related products have a wide market space in the whole process of power production, which bring new opportunities for power distribution development from automation to intelligentialize, and provide technical supports for the power metering system platform. Because of the importance of...

Abstract Aiming at the problems of long error correction time and poor effect electric energy metering device, an automatic algorithm design is proposed. First, stationary characteristics device when errors occur are extracted, regular interval found. Second, in interval, average power quantization determined, location Finally, stability corrected according to error. According position, model c...
