Please note that the content of the website has not bee updated for over many years. Currently the site mainly contains some of the work I did in undergrad and graduate studies. A lot of the old tutorials/notes have been moved to the Wiki.
The objective of this report is to discuss major interior home technological trends in the next ten years. Networking, monitoring, automating, and digitalizing are the four major trends. I relied on "George Washington University Forecast", British Telecommunication exact timeline, the popular media "buzz", and my background as an engineer to identify the trends. Networking allows devices to use the information on the...
Type: ArticleThe journal entries examine the following undamental paradox of modern society: "Technology has made enormous powers available to society, yet we as individuals exert very little of that power". The journal will address the paradox in the context of engineering. Engineering produces technology, by understanding the intent of engineering decisions, the choice of problems by engineers, and to the degree to which engineers exercise "power" of technology the paradox...
Type: ArticleAll beings at certain station in their life wonder about the nature and meaning of them, and their existence. A suitable explanation to such elements is necessary to lead our day-to-day life. Lacking of an explanation may devoid our life of goals and could lead to despair. However, to arrive at the suitable explanation is not a mechanical process. Science and Religion offer promises of the solution. Science offers exploration of the universe and potential for...
Type: ArticleExcuses are constructed as explanations for our failings or lack of actions. We use excuses to explain our choices and conditions. The tone of excuses is to deny the possibility that our choices or conditions could not be otherwise, and to deny that we possessed freewill. The term excuse is taken in the strictest meaning, cheating ourselves that things could not have been otherwise.
How do we explain excuses? We cannot dismiss excuses as just a...
The existence of God has not been proven undoubtedly. Arguments from entrusting "holy" and historical documents, design arguments, the "ontological argument" and cosmological arguments seek to prove the existence of God from distinct point of views. Cosmological arguments raise the question of "how things are here?. In attempt to answer the question they assert the existence of God. The purpose of this essay is to show how cosmological arguments try to answer "...
Type: ArticlePhase Locked Loop is an important circuit found in various communication devices, and here studied in a set up to synchronize input and local carrier signals for coherent demodulation of AM signals. PLL consists of a phase detector, a loop filter, and a voltage controlled oscillator. The phase detector and loop filter combined produces an error signal which amplitude is linearly related to the phase difference of input and local carrier signals. The voltage-...
Type: ProjectIn the developed world, scientific technologies improve health care, education, management, transportation, communication, recreation, and security. Also, the problems of obesity, the threat to privacy, mad consumerism, and environmental degradations are linked to scientific technologies. Although pockets of Asia and Africa experience parallel use of scientific technologies, more than half of the communities do not have access to the...
