In this paper, we give an overview of the power line communication (PLC) technology. This paper presents an overview of the research, applications, standards and importance of the power line communication. Power line communication is an emerging home network technology that allows consumers to use their already existing wiring system to connect home appliances to each other and to the Internet....

This paper presents techniques derived from empirical modelling methods and especially designed to tackle the recognition of dynamic transients with the aim of detecting and diagnosing faults and anomalies in equipment and processes. Applications and results are also presented, covering BWR and PWR plants and spanning from component level diagnostic applications to sub-system and plant level di...

This paper presents a fully differential opamp desing based on the switched-opamp approach. The common mode feedback of the proposed opamp only works on the output stage in order to allow a fast turn-on. The opamp was designed in a 0.35 m CMOS technology and is able to operate from a single 1V supply.

In this paper we present a new approach to evaluate the environmental efficiency of decision making units. We propose a model that describes a two-stage process consisting of a production and an end-of-pipe abatement stage with the environmental efficiency being determined by the efficiency of both stages. Taking the dependencies between the two stages into account, we show how nonparametric me...

In this paper, we propose a circuit that computes the area under a difference waveform and produces it's analog value as output. The transient waveforms pair from which the difference is computed is given as input to the circuit. The circuit is proposed as a hardware solution for a device testing technique called Transient Signal Analysis.

introduction: the aim of this study was to determine the histologic effect of low level laser therapy (lllt) with or without the use of mineral trioxide aggregate (mta) on exposed pulp tissues of dogs. methods: twenty-five premolar teeth in three healthy mature dogs were randomly divided into five groups. in group 1, the pulp tissue was capped with mta. in groups 2 and 3, before capping with mt...
