Research Questions
The primary goal of this paper was to examine the validity of four sets of hypotheses that stem from four central research questions:
1.) Can prognostics be successfully implemented on electronic circuit cards that have embedded diagnostics?
The reason this research question was chosen is that prior research indicates that there have been no successful instances where prognostics have been implemented on electronic circuit cards. The cases that were presented in the prior research were all unsuccessful because of modeling uncertainties, the lack of intelligent algorithms, and the lack of technical exploration in electronic prognostics (Saxena, Celaya, Saha, Saha, & Goebel, 2010; Tang, Kacprzynski, Goebel, & Vachtsevanos, 2009). The proposed method uses simpler (lighter) algorithms that are customizable to the end-user needs. Successfully answering this question will allow electronics to become cheaper, more reliable, and better position businesses to increase their profit margins. The expected outcome of this question is that prognostics can be implemented on electronic circuit cards through the use of the proposed simpler (customizable) algorithms.
2.) Will implementing prognostics affect the overall delivery time-to-market?
The reason this research question was chosen is that if a business is in a market where the delivery time-to-market is short, they may not be able to see the value-add or the return on their investment for implementing prognostics. The reason the answer to this question is important is that design engineers may be tied down trying to design in the parameters of prognostics. The time spent on adding in prognostics to a design (time when the product is not being sold), potentially ...

...t will bring value-add ultimately to the end-user.
H4o: The use of the proposed prognostic-algorithms will not allow design engineers and businesses to customize areas of focus (reliability, cost, lowest/highest component replacement, lowest/highest system replacement, and other areas of concern) and the algorithms will not bring value-add to the end-user.

Essay on Implementing Prognostics Within the Telecommunications Industry

- The results show that four categories (non-reliable testing, unintelligent prognostic algorithms, inadequate fault detection, and data archiving) were affecting mission readiness. The findings proved to be logical because the government has adopted this medium for diagnostics as a solution for legacy test system upgrades but they are examining ways to implement real time prognostics. The author’s conclusions were sound and lucid; and he developed a medium to reduce rework times, reduce yearly preventive maintenance, reduce repair times, and finally serve as a catalyst for accurate fault detection....   [tags: Research Analysis ]

Essay on Study in Electronics and Communications Engineering

- At the dawn of the information age, to be young, as Wordsworth said in another context, is very heaven. Getting to know what goes inside computers, the engines of the Information Technology revolution, and knowing how to work with them enables one to understand the technology that makes it all possible. Understanding this, I chose to do my undergraduate study in Electronics and Communications engineering. Prior to that, I had a fairly normal educational career. I did well through my high school and worked hard to get undergraduate admission in the field of my interest in one of the most reputed engineering colleges in my state, SNIST, JNT University....   [tags: electronics, computers, technology]
