Evidence-informed decision making for nutrition: African experiences and way forward
(Cambridge Univ Press, 2017)
Although substantial amount of nutrition research is conducted in Africa, the research agenda is mainly donor-driven. There is a clear need for a revised research agenda in Africa which is both driven by and responding to ...
Evaluation of bio-char based products as hydrotreating catalysts for the production of renewable fuel
Increasing demand for alternative fuel from fossil fuel exists which has led to the development of new technologies for the production of bio-fuels. One such technology involves the hydrotreatment of vegetable oils such ...
Induction motor efficiency test methods: a comparison of standards
Improved efficiency is the task of the hour. Environmental challenges, which include climate change, global warming and greenhouse gas emission have been fuelling the need to increase energy efficiency in electrical rotating ...
Time of flight secondary ion mass spectrometry and high-resolution transmission electron microscopy/energy dispersive spectroscopy: a study of the distribution of hazardous elements in coal ashes
(International Pittsburgh Coal Conference, 2017)
Impact on power factor by small scale renewable energy generation
Domestic installations traditionally were believed to be resistive in nature and did not affect power factor much, if at all. With increasing affordability of air-conditioners, and replacement of electrical geysers with ...
Evaluation of design and planning parameter impact by energy efficient measures through appliance-based modelling
In a rapidly evolving industry as a result of consumer self-generation and a drive to become more energy efficient, it is necessary to understand whether traditional network planning methods are sufficient. Electrical ...
Fingerprint matching on smart card: a review
Fingerprint Match-on-Card (MoC) offers the highest degree of privacy and security to cardholders as the fingerprint never leaves the secure environment of a smart card. The level of security of a biometric system is evaluated ...
2D methods for pose invariant face recognition
The ability to recognise face images under random pose is a task that is done effortlessly by human beings. However, for a computer system, recognising face images under varying poses still remains an open research area. ...
Centaurus A: hard X-ray and soft gamma-ray lightcurve correlation
(Sissa Medialab, 2017)
Centaurus A (Cen A), powered by a 55 million solar mass supermassive black hole, has been intensively monitored in all accessible wavelength ranges of the electromagnetic spectrum. However, its gamma-ray flux, both in the ...
Why the universe is unexpectedly transparent to very high energy gamma rays
(Sissa Medialab, 2017)
Recent observations of distant gamma ray sources indicate that the universe may be more transparent to VHE-gamma-rays than expected. In this paper we study the reduction of the EBL gamma-gamma opacity due to the existence ...
