Different aspects of assessment of engineering Ph.D. thesis

Would you like to know what engineering examiners expect of Ph.D. research?

In the article “An analysis of Ph.D. Examiners’ Reports in Engineering”, from European Journal of Engineering Education. the authors, Elena Prietoa, Allyson Holbrooka & Sid Bourkea examine the different aspects of the assessment of engineering doctorates. Their work is based on the data collected between 2003 and 2010 for a total of 1220 Australian Ph.D. theses by analysing examiner reports.

They point out that examiners in engineering favoured theses they considered were strong in terms of scope, significance and contribution, and a thorough analysis of findings. Other factors that have direct correlation to the quality of thesis as highlighted by the authors are breadth, depth and recency of the literature review, communication and editorial correctness of the thesis. Publications arising from the thesis also determine the quality of the thesis, even though they  have lesser significance.

This is one of the popular articles in Taylor & Francis journals published in 2015.

Fluorine in organic molecule

The hyrophobic (water resistant ) and lipophylic (ability to dissolve in fat-like solvent) characteristic of -CF3 group are important to aid in transportation of therapeutic drug to the active site in the body. Moreover, drug’s stability properties is improved due to strong carbon-fluorine bond.“These factors are crucial for the development of therapeutic drugs and agrochemicals,” says Sodeoka  (Efficient and versatile chemistry (2012, Oct 05).

Mikiko Sodeoka and her colleagues at the RIKEN Advanced Science Institute in Wako has successfuly develop an efficient  reaction to insert the -CF3 group into organic molecule through the formation of allylsilane, another functional group comprised of silicone, using copper catalyst.

[Article]: HEADER COMPRESSED VOIP IN IEEE 802.11

With the proliferation of wireless network, one area will become popular – real-time multimedia applications. The development of header compression technique will also bring improvement to the wireless access.

In this article, the authors described how a robust header compression (RoHC) can be used to reduce the overhead of IP-based traffic. And Voice over IP (VoIP) may replace the voice circuits in the future wirless network applications (IEEE 802.11 technology).

A simulation study of the RoHC’s U-mode performance when applied to VoIP in an 802.11 link is described.
