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...

A key issue for the success of a smart grid is the capability to accommodate efficient smart metering. Following the trend towards timely monitoring of energy consumption and production via Internet related technologies and in-network metering platforms, we need to investigate performance-related aspects of smart metering and how they affect the overall operation. We present here our experience...

The article analyzes the structures of measuring channels electricity metering systems. It is shown that such a structure determined by types instruments used and scheme their connection, in particular, meters installed at points. Moreover, counters can have pulse or interface information output. path for includes circuit consisting current voltage transformers, an meter, communication lines, d...

In this study, the discrete element method was used to optimize bucket size for metering device in a garlic planter enhancing productivity of farming according size. Statistical information concerning actual shape cloves incorporated, and mechanical properties were determined using bulk density, sliding test, repose angle test fidelity simulation model. The optimal achieving target plant rate 9...

More and more metering schemes based on some special protocols or mechanisms are used to calculate the number of visits which a website receives in a certain time frame. Then, the amount of money that an advertiser pay to a website depends on this number of visits. Until now, many protocols were suggested for metering schemes in literature. However, the discussion mainly focused on the theory o...

Critics of current tying doctrine argue that metering ties can increase consumer welfare and total welfare without increasing output and that they generally increase both welfare measures. Contrary to those claims, we prove that metering ties always lower both consumer welfare and total welfare unless they increase capital good output. We further show that under market conditions we argue are r...

High quality heating device made of ferromagnetic alloy (thermal seed) was developed for hyperthermia treatment of cancer. Ferromagnetic seeds of PdNi, PdCo and CuNi are prepared by induction furnace and subsequent heat treatment. Magnetic induction and hysteresis loops are measured as functions of temperature. The power dissipated from each seed was calculated from the area enclosed by the hys...

A metering scheme allows a correct counting on the number of hits that a Web site received during a certain period. In this paper, we first derive tight lower bounds on the communication complexity |Vi| (i = 1, . . . , n) and the size of server’s secrets |Es| for robust and perfect (k, n)-metering schemes. We next show an almost equivalence between (k, n)-metering schemes and k-multiple-use A-c...

Recently appeared necessity of enterprises, homes and other objects energy consumption information automatic collection. For this purposes various metering devices by different vendors have been created. While using different metering devices, problem of central information collecting appears. This paper raises the problem of creating a web-interface for metering devices remote monitoring syste...
