The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

Power transformers are important and expensive components in the electric power system. The knowledge of the actual status of the transformer insulation behavior, load tap changer performance, temperature, and load condition is necessary in order to evaluate the service performance concerning reliability, availability and safety. Systems abnormalities, loading, switching and ambient condition n...

This paper reports the findings of a humancomputer interaction (HCI) experiment, conducted to determine whether graphical or textual representations of a simulated load monitor are more effective at communicating notification information in a secondary display. We establish guidelines for design tradeoffs based on significant differences in display facilitation of information monitoring, awaren...

Bridge management officials have expressed a keen interest in the use of low-cost and easy-to-install wireless sensors to record bridge responses during short-term load testing. To illustrate the suitability of wireless sensors for short-term monitoring of highway bridges, a wireless monitoring system is installed upon the Grove Street Bridge to monitor structural responses during static and dy...

In the absence of widespread access to individualized laboratory monitoring, which forms an integral part of HIV patient management in resource-rich settings, the roll-out of highly active antiretroviral therapy (HAART) in resource-limited settings has adopted a public health approach based on standard HAART protocols and clinical/immunological definitions of therapy failure. The cost-effective...

In this paper we present a new methodology for the formulation of efficient load signatures towards the implementation of a near-real time Non-Intrusive Load Monitoring (NILM) approach. The purpose of this work relies on defining representative current values regarding the 1st, 3rd and 5th harmonic orders to be utilized in the load signatures formulation. A measurement setup has been developed ...

For the last couple of years, due to ecological as well as economical reasons, energy efficiency of ICT has become a major issue. Leading manufacturers of IT equipment advertise with ”green” and energy-efficient products. Steadily increasing energy consumption in data centers [1], as well as high electricity costs prompt organizations, companies, and administration to decrease the energy consum...

Fog computing, a non-trivial extension of cloud computing to the edge of the network, has great advantage in providing services with a lower latency. In smart grid, the application of fog computing can greatly facilitate the collection of consumer’s fine-grained energy consumption data, which can then be used to draw the load curve and develop a plan or model for power generation. However, such...

Die präzise Erfassung der Belastung und Beanspruchung eines Trainings kann zu einer verbesserten Trainingssteuerung und zur Vermeidung von Übertraining führen. In der Literatur wurde bisher keine einheitliche Gold-Standard-Methode zur Messung der Trainingsbelastung oder -intensität von Ausdauerathleten präsentiert. Das Ziel dieser Publikation ist i) die Identifikation von validen, praktisch anw...

One of the most important design decisions in Non-Intrusive Load Monitoring (NILM) systems is choosing which electrical parameters will be used to define load signatures. In this paper, we present an experimental study where several electrical quantities of common home appliances were measured, in order to identify the most adequate to perform load disaggregation. It was found that active power...
