Research ArticleOpen accessAll words, across the recordThermal Comfort Assessment-A Study Toward Workers’ Satisfaction in a Low Energy Office BuildingMohd Nafiz Shaharon, Juliana JalaludinProblem statement: The government of Malaysia has raised their concerns towards the issue of workers comfort and workspace quality in a Low Energy Office (LEO) building. New energy efficient building concepts and technologies require a revision of comfort standards, to create a suitable thermal condition in avoiding occupant dissatisfaction, adverse effect on their productivity and overall building performance. Approach: Assessment … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 16 May 2012 · 8,802 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordExperimental and Skeletal Kinetic Model Study of Compressed Natural Gas Fueled Homogeneous Charge Compression Ignition EngineP. M. Diaz, B. Durga Prasad, D.S. Manoj Abraham, K. PalaniKumarProblem statement: In homogeneous charge compression ignition engines fuel oxidation chemistry determines the auto-ignition timing, heat release, reaction intermediates and the ultimate products of combustion. To shorten development time and to understand combustion processes, the use of simulation is increasing. Approach: A model that correctly simulates fuel oxidation at these conditions would be a useful design tool. Detailed models of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 22 Mar 2012 · 7,258 accessesView PDF Cite
