On Developing a Powertrain in a Hybrid Car with Electricity and Compressed-Air Propulsions

Authors: Mohammad Mansouryar
Comments: 60 pages.

A hybrid car with two propulsions of compressed-air and electricity is outlined. To fill up the compressed-air tanks, two methods of electrical and manual air are proposed. The electric propulsion is based on two collections of storing batteries and capacitors. The desired batteries are lithium-ion [1] and the desired capacitors are supercapacitors [2], in which they could store a significant amount of electric energy.

A Simple Method to Determine Surface Albedo Using Digital Photography

Authors: Glen Gilchrist
Comments: 6 pages

Surface albedo is an important concept, useful in explaining how closed systems (such as the Earth - Atmosphere) respond to incident radiant energy. Specialist, calibrated equipment is used by geo-scientists to measure ambient and reflected radiation from subject sources - this is often cost prohibitive within a teaching environment. A "semi" calibrated method is presented, utilising simple digital photography of both reference and subject sample. Using the "levels" function built into freely available image editing software, a simple algorithm is presented that allows a relative reflectance of the sample image to be calculated. Processing this with relation to a calibrated image allows for the simple determination of surface albedo. Using this method, albedo levels within 3% of a calibrated meter are obtained.
