2013 W. M. Keck Institute for Space Studies Postdoctoral Fellowship Program
Application Deadline: 12 Noon PST 28 November 2012
The W. M. Keck Institute for Space Studies (KISS) at the California Institute
of Technology announces an opportunity for highly qualified individuals to
apply for postdoctoral fellowships to conduct research in space science and
engineering. The primary purpose of KISS is to develop breakthrough planetary,
Earth, and astrophysics space mission concepts and technology by bringing
together a broad spectrum of scientists and engineers for sustained scientific
Discussion Topic 1: Rank top ten severe accidents in energy sector (Aberfan Disaster)
(1) What were the
physical/technical circumstances that led to the accident?
The spoil tips produced by the mining process were placed on top
of a layer of porous sandstone that housed a number of underground springs. On
the lead up to the disaster it had been raining heavily for days which caused approximately
3-6 meters of the spoil tip to subside.
(2) What were the main
underlying causes?
In recentyears, millions of solar panels have been placed on roofs around the world. Discuss how safe are they? Discuss the hid
Installing
solar panels on rooftops are obviously a high risk activity. There are a number
of hazards such as working at heights which could lead to falls from heights or
falling objects. Also slippery roof surfaces, damaged roofs, electrical
discharge from uninstalled panels, electrical fitting and equipments are all
potential hazards. All these, when not properly controlled could lead to
undesired conquences.
Reivew of fracture toughness testing and standardization
Recently, a comprehensive review paper on fracture toughness testing and ASTM standardization was published by Dr. Zhu and Prof. Joyce in the journal of Engineering Fracture Mechanics:
XK Zhu and JA Joyce, "Review of fracture toughness (G, K, J, CTOD, CTOA) testing and standardization," Engineering Fracture Mechanics, 85, 2012: 1-46.
Welcome your comments and suggestions.
Case Studies in Engineering Failure Analysis - New Journal welcoming submissions!
We are very pleased to announce the launch of a new journal in the field of mechanical engineering, Case Studies in Engineering Failure Analysis. This journal provides a forum for the rapid publication of short, structured Case Studies in Engineering Failure Analysis and related Short Communications and will provide an essential compendium of case studies for practitioners in the field of engineering failure analysis and others who are interested in the ways in which components fail.
In recentyears, millions of solar panels have been placed on roofs around the world. Discuss how safe are they? Discuss the hid
In recentyears, millions of solar
panels have been placed on roofs around
the world. Discuss how safe are they? Discuss the hidden pollution
caused by solar panels.
Shale Gas Fracking
Fracking is the process of drilling down and creating tiny
explosions to shatter and crack hard shale rocks to release the gas inside.
Enough water, sand and chemicals are used in the production of shale gas. [1]
PhD "CIFRE" position at UTC/Renault "Thermal design of Lithium battery for an electric vehicle" (closed)

1- Research areas
General area :
The battery is known for its strict requirement of the lowest maximum allowed working temperature in the entire electric transmission chain assembly. This poses a problem particularly in climates with extreme temperature variations (35-45°C in summer and 0 to -30°C during winter) and during fast recharging at a significant battery power level.
