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.

The key role of chemokine receptor CXCR4 in the maintenance of stemness property of stem cells has been shown recently. The low level laser irradiation (LLLI) is being used currently in a wide variety of clinical cases as a therapeutic tool for wound healing, relieving pain and destroying tumor cells. The aim of this study was to evaluate the effect of LLLI mimicking low level laser therapy (LL...

aim and background:   knee osteoarthritis (oa) is a prevalent and disabling disease. periarticular corticosteroid injection has been traditionally used for the pain control in these patients. recently low power laser has been introduced as a therapeutic option. this study was conducted to evaluate the efficacy of low power laser added to periarticular steroid injection for long-term treatment o...

one of the basic purposes in dental treatment is providing a painless treatment for patients. this purpose may be achieved by the application of laser in dentistry. low-level laser therapy (lllt) is an internationally accepted title for biomodulation with low-level lasers which we use to achieve ideal therapeutic effects. low-level laser therapy is a painless, reproducible, non-invasive, and wi...

introduction: chemotherapy-induced oral mucositis (com) is a common, debilitating complication of cancer therapy. the aims of this study were to evaluate the effect of low level laser therapy (lllt) on prevention of com in patients with hematologic malignancies. methods: fifty-five patients hospitalized to undergo chemotherapy in imam hospital were included into the study. these patients were d...
