In this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of Iran. Four stations in Khuzestan- Abadan, Hosseyneh, Mahshahr, and Shushtar- are analyzed to determine the potential of wind power generation in this province. From the primary evaluation and by determining mean wind speed and also the Weibull f...

STUDY OBJECTIVE In a previous study a higher than expected prevalence of asthma was found in Lake Munmorah, a coastal town near two power stations, compared with another coastal control town. This study aimed to compare atopy, bronchial hyperreactivity, and reported symptoms of asthma in the power station town and a second control area with greater socioeconomic similarity. DESIGN A cross sec...

The overall contribution of cellular network operators to the entire human CO2 emissions is estimated at 2.5% in the U.S. [1]. Thereinto, about 60%− 80% originates from wireless base stations (BSs) [2]. As current cellular network architectures are designed to cope with peak load and degraded conditions, underutilization of them occurs most of the time. A recent study [3] shows that the average...

In this paper, a power consumption model for both macrocell and microcell base stations is proposed. This model is validated by temporal power measurements on actual base stations and an excellent agreement is obtained. Furthermore, the power consumption’s evolution during the day is investigated by means of these measurements. The energy efficiency of three different wireless technologies is c...

Performance benchmarking plays a major role in setting and maintaining the objectives of the operational units. Traditional productivity measures are found to be inadequate in assessing the performance and hence advanced techniques like Data Envelopment Analysis (DEA) are recommended. This paper demonstrates the use of DEA for benchmarking the performance of electricity generating and supply st...

Within the field of power generation, aging assets and a desire for improved maintenance decision-making tools have led to growing interest in asset prognostics. Valve failures can account for 7% or more of mechanical failures, and since a conventional power station will contain many hundreds of valves, this represents a significant asset base. This paper presents a prognostic approach for esti...

Given a finite set S of points (i.e. the stations of a radio network) on the plane and a positive integer 1 ≤ h ≤ |S| − 1, the 2d Min h R. Assign. problem consists of assigning transmission ranges to the stations so as to minimize the total power consumption provided that the transmission ranges of the stations ensure the communication between any pair of stations in at most h hops. We provide ...

The Institute of Seismology of University of Helsinki is building a new local seismic network, called OBF network, around planned nuclear power plant in Northern Ostrobothnia, Finland. The network will consist of nine new stations and one existing station. The network should be dense enough to provide azimuthal coverage better than 180 and automatic detection capability down to ML −0.1 within a...

With the global trend to exploit more renewable energy sources, tidal range has been gaining attention recently. This power generation technology is expected reduce share of fossil fuels and provide flexibility system. a pioneering project just granted in Wales proposals planned Great Britain, it important study how incorporation multiple stations will affect system operation. In this paper, ro...
