Designing an optimization of vertical axis wind turbine Wind turbines have in the recent past been adopted as the main source of renewable energy. The vertical wind turbines have proved to be very efficient due to their ability to be used in small scale. A report authored by Hamid Rahai and Hamid Hefazi (2005) entitled: Development for Optimum Design configuration and Performance of Vertical Axis Wind Turbine(VAWT), points out that vertical axis turbines are cheaper to install than the horizontal axis wind turbines. However, the report shows that the research have shown that they are less efficient than their counterparts. This is the biggest impediment to the full commercial adoption of these machines. This report that was prepared for the California Energy Commission points out that through optimization, redesigns can be done to increase their efficiency (p. 5). Hamid Rahai and Hamid Hefazi (2005) report in this article that one of the ways of achieving efficiency is the ab

Applying Communication Theory in Everyday Situations Communication plays a big role in the day to day life. The term can be defined differently depending on the context. For instance, in business, it refers to the flow of information from one person to another. However, communication scholars have been able to define it as the process by which people interactively create, sustain and manage a certain meaning (Conrad & Poole, 1998). This is a clear indication that communication is key component in giving meaning to how and what goes on around us. To get a clear understanding of how communication can analyzed, theories are used to help us get the deeper meaning and the application in life. There are numerous theories that have been formulated to help explain the world view of different communication modes and forms. Theories are important in their ability to make communication process more understandable. However, theories can also hide or distort the communication. One of t
