Garrett Kurtz 11/27/12 Religion 101 Religious Phenomenon’s When reading both of these articles the one that really stood out to me in terms of interest was the article Women & Islam: The rise and rise of convert. This article really stood out to me because of the staggering statistics about how many of the converts was women. During the last decade 100‚000 Britons have converted to Islam from their previous religion and seventy percent of the converts were women (Peppiatt 1). This statistic

Beginning in 1968‚ the second generation of Cutlasses were born. This generation had a shortened wheel base and larger motors in comparison of its predecessors. In 1969‚ only one year into the second generation‚ the cars

paper describes the control and design of a Doubly Fed Induction Generator (DFIG) using back-to-back PWM converter in wind turbines. A back-to-back PWM converter is used as the excitation power supply for the DFIG wind power generation of variable speed constant frequency. The Simulink model and control strategy of converter which is connected to grid side is analyzed. The grid side converter is used to regulate the voltage of the DC link capacitor. Besides it satisfies the unity power factor of
