A hybrid renewable energy system consisting of a photovoltaic generator and a wind driven DC machine is interconnected with the power utilities grid. The interconnection is done through the use of two separate single phase full wave controlled bridge converters. The bridge converters are operated in the “inverter mode of [...]

Pure and Cu +2 doped TiO 2 thin films have been successfully deposited onto glass substrate by sol–gel dip-coating. The films were annealed at 450 °C for 1 h and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM-EDX), atomic force microscopy (AFM), UV–vis spectrophotometer and photocatalytic degradation of methylene [...]

Detecting replay attacks in power systems is quite challenging, since the attackers can mimic normal power states and do not make direct damages to the system. Existing works are mostly model-based, which may either suffer from a low detection performance or induce negative side effects to power control. In this [...]

The purpose of this research was to propose and build a sustainable, low-impact, optimized, modular lodge, to facilitate scientific studies in the Antarctic. Within this unique climate, this paper presents new environmental and sustainable approach for the extreme cold. The Polar Lodge was designed and built with a primary concern [...]

The photovoltaic performance of dye sensitized solar cells using Al-doped ZnO thin films (ZnO:Al) grown onto ITO substrates as photoanode and natural dye as sensitizer had been studied. The effects of [Al/Zn] ratio on structural, microstructural, optical and electrical properties of these films were investigated. X-ray diffraction analysis of pure [...]

The knowledge of irradiation in a geographical area is very important for multiple areas for the development of the area. Current calculation systems are based on statistical models of measurements of ground stations, or by external radiation calculations by satellite models. In this paper we show another method of calculation, [...]

The Kingdom of Bahrain falls geographically in one of the driest regions in the world. Conventional fresh surface water bodies, such as rivers and lakes, are nonexistent and for water consumption, Bahrain prominently relies on the desalination of sea water. This paper presents an ongoing project that is being pursued [...]

This article shall investigate the feasibility of utilizing wind energy for commercial buildings with special reference to the Kingdom of Bahrain. Bahrain World Trade Center which was built in 2008, is located in the city of Manama. The fifty-story complex contains identical twin towers that rise over 240 meters in [...]

Wind energy has become an attractive alternative to satisfy the ever-growing energy demands worldwide. One important factor that contributes to efficient energy harnessing from a wind farm is the selection of appropriate wind turbines for a specific site. This paper addresses this important issue through a goal programming based multi-criteria [...]

This article focuses on the asset price volatility at the stock exchange that result from the regime switching behaviour in the market. This study is devoted to the question about how the asset price volatility affects the US sovereign debt market. The efficient market hypothesis has been a base for [...]
