The recent announcement of the new Saudi Arabia’s plan to drastically decrease the role of oil in the economy and to diversify the governmental revenues has received wide coverage in media. Two famous newspapers, New York Times and The Economist also issued the articles covering the topic. Ben Hubbard in the New York Times article “Saudi Prince Shares Plan to Cut Oil Dependency and Energize the Economy” provides a detailed information about Prince Mohammed bin Salman’s economic plan to reform Saudi economy, while The Economist’s article “Beyond Oil: Change in Saudi Arabia” is a brief account ...

Abstract

This paper analyzes the importance of generator synchronization to the power grid, the required conditions to perform this procedure and the consequences of imprecise synchronization. For a generator to be synchronized to a grid, the voltage magnitude, frequency, phase sequence and phase angle must match. Manual synchronization depends on an operator to modify generator voltage and frequency, confirm phase sequences of generator and grid, and monitor phase angle difference to timely initiate breaker closure. Automatic synchronizers perform all these function through a computerized system that consists of complex algorithms and control systems, and are categorized in phase lock type ...

Growing up all children are told “drugs, and especially marijuana” is bad. As children, one never gets to understand why they are given such caution especially when they do not know what drugs are and the effect they have on individuals and society. But rules are to be followed regardless. As one gets older, they are faced with the grave realities of what adults told them especially when they see the devastating effects drugs have on those who use them uncontrollably. The rude shock sets in when people everywhere seem to enjoy the use of drugs such as marijuana, ...

Management is associated with poor motivational policies in the criminal justice organization. The hierarchy and protocol management system tend to affect motivational issues in the agency. The administrator in the criminal justice system is unaware and indifferent of the importance of values and motives of employees. The criminal justice ...

Introduction

Numerous electrical applications require an inverter, which converts Direct Current (DC) to Alternating Current (AC) power. Some of these applications require the stepping down of voltage levels when realizing this conversion, which signifies that the input DC power is greater than the AC power. Conversely, certain applications require the opposite: to step up voltage when performing the power conversion, which means that the input DC power is lower than the AC power. These requirements can be met through the use of Voltage Source Inverters and Current Source Inverters, respectively. However, some particular applications require to step down voltage for ...
