Cogeneration is possible using the cooling water that maintains the cold sink, so heat-and-power systems for homes are provided. With higher efficiencies, their quiet vibration-free operation, very low emissions when burning natural gas, simplicity, and potentially high reliability could make the Stirling engines an attractive alternative in the near future [6]. Simulation and modeling can be used to evaluate the operation of the solar Stirling engine based power generation systems. Considerable research has been performed on the modeling and control of Stirling engine systems. Most of this research, however, has been done using mechanical and thermal models of Stirling engines that neglects the electrical parts of the system [5], [7], [8]. In this research...

...EXECUTIVE SUMMARY The Royal Australian Navy’s Collins Class Submarine is designed to replace the 30 year old Oberon Submarines. The Collins Class is the first submarine to be made in Australia and is the most advanced of its time due to its software architecture. Deep Trouble addresses various issues that were faced during the design and development stages of the Collins Class project. This report will focus on the interrelationship between the three PMBOK knowledge areas of scope, procurement and quality management and the impact each had on the final project. The Collins Class submarine was prone to excessive noise signatures whilst travelling at speed and lacked the operational capability to enter conflict situations due to the an insufficient combat system. The selection process for the design of the Collins Class and the fundamental capabilities the navy required directly impacted the quality of the final product due to the scope of the design not being fully understood by the manufacturing companies. The Collins Class project was an opportunity for Australia to become a ‘technological powerhouse’ by having the Collins Class submarines built within Australia. This report addressed how certain issues discussed within Deep Trouble impacted the knowledge areas of scope, procurement and quality management within this complex project and how the interrelationship between them contributed to a submarine that has adversely weakened our national defences. ...

...CHAPTER 1 INTRODUCTION 1.1 Background of the Study In this age of industrialization and globalization, the importance of electricity is unquestionable. Considered as one of the basic needs of mankind, it is essential not only in performing household tasks or maintaining livelihood activities, but also in improving people’s well-being. Through electrification, people have greater access to productivity and developments in technology, infrastructure, health, education, communication, and even modern and sustainable livelihoods. However, despite its importance there are still many households especially here in Mindanao which do not have connection to electricity. Based on the results of the 2008 Annual Poverty Indicators Survey, two in every five poor Filipino families living in the urban or rural areas do not have electricity in their homes (National Statistics Office, 2008). The reason for this is the high cost of electricity.For the economically disadvantaged, electricity is considered a luxurious necessity. Another problem that confronts electricity utilization both in the urban and rural areas is the frequent power rate increase and the prevailing power shortages. Based on the situation here in Iligan City as of May 2013, insufficient power supply caused Iligan Light and Power, Inc. (ILPI) to purchase additional 10 MW from MPC (Mapalad Power Corporation). This resulted to increase in power cost from Php 6.53 per kWh to Php 7.67 per kWh. With the increase in demand, possibility...

...Back in the 70s and early 80s, historical journals and essays failed to include film as a possible medium to portray history. Even if a film were an accurate depiction of past events, it would not be recognized by any historian to be legitimate. However, nowadays almost all major journals publish reviews, analysis, and essays on film and is recognized as valid. Mel Gibson’s 1999 film Braveheart is a clear example of why historians never accepted film. Although it won 5 Oscars, the film has been classified as one of the worst medieval movies (by historical accuracy). From the introductory opening scenes, to the end credits, the film fails miserably to represent the life and times of William Wallace and makes up stories to better fit a Hollywood audience. In this essay, I will examine the historical facts of the 13th century war between Scotland and England, and the way it was portrayed in Braveheart. Directed and starred by Mel Gibson, Braveheart was seen as a huge success. The film was about a man named William Wallace. Wallace was a commoner and landowner in 13th century Scotland. He led the Scottish rebellion against the English to get back the freedom and sovereignty Scotland deserved. He was knighted and titled “Guardian” of Scotland after a victory in the battle of Sterling Bridge. After losing the Battle of Falkirk, Wallace’s rebellion plummeted and he was later captured and executed for high treason by King Edward I. These are the very few facts the film actually illustrated...
