  • Design and Simulation:These are some books which are recommended as a reading list. 1- Aerodynamics of Road Vehicles from Fluid Mechanics to Vehicle Engineering. Edited by Wolf-Heinrich Hucho 2- Hucho-Aerodynamik des Automobils Stromungsmechanik.Warmetechnik. Fahrdynamiik.Komfort
  • Optimizing Performance and Fuel Economy of a Dual-Clutch Transmission Powertrain with Model-Based Design.
  • Wind Turbine DesignPrimary objective in wind turbine design is to maximize the aerodynamic efficiency, or power extracted from the wind. But this objective should be met by well satisfying mechanical strength criteria and economical aspects. In this video we will see impact of number of blades, blade shape, blade length and tower height on wind turbine design.
  • Modelling Complex Mechanical Structures with SimMechanicsModeling physical components or systems in Simulink® typically involves a tradeoff between simulation speed and model fidelity or complexity: the higher the fidelity of the model, the greater the effort needed to create it..
  • Biomass Energy Vs. Natural GasIn 2009, natural gas prices plunged to below $4 per MMBtu where many "Experts" are saying that prices will remain low for decades as a result of technology break-throughs allowing for sizable increases in natural gas supply for North America. The Energy Information Agency (EIA) just released data projections reflecting this potential increased supply in natural gas.

Current Ethanol Vs. Gas Prices (4/20/2012)

Posted by Sohail Azad On 01:39

Tracking gasoline prices versus ethanol prices. The pink line is commodity price of ethanol (which has less efficiency than gas, E-0). The green line line adjusts for this lower efficiency, allowing an "Apples to Apples" comparison with the commodity RBOB price of gas (the blue line). The red line is the average retail price of gasoline in U.S. As of April 20, 2012 -- ethanol is about 8� per gallon cheaper than gasoline on a wholesale price comparison....

Is it possible to accurately estimate production in mining operations?

Posted by Sohail Azad On 18:29

1. Mines are �Complex Systems�Mine operations consist of multiple �stochastic dependent processes� interconnected through a wide range of complex relationships. Let�s analyze this proposition.1.1. Mining processes are stochastic in natureVariability is inherent to mining operations. Each mining process is subject to variability. Examples of this inherent variability are:Time to load truck 'A' is not equal to the time to load truck 'B'. Travel...
