Engine performance depends on two main factors of engine speed and ignition time. Ignition timing can affect engine life, fuel economy and engine power. In this paper, to study engine performance of Peugeot 206 TU3A with comparison ratio of 10.5:1 and displacement of 1361CC in MATLAB software, a two-zone burned/unburned model with the fuel burning rate described by aWiebe function was used for ...

the purpose of the present study was to examine the effects of self – control modeling , that is presenting moded to learner whenever they asked for it, on learning a timing task.twenty four right handed subjects (12 males, 12 females, aged 19-20) voluntarily participated in the study and were assigned randomly to two groups of self – control and yoked.the task was pressing the keys number 1, 4...
one pollutant which seriously threatens water resources is dye. therefore, finding a suitable method to separate the dye in water resources is very important. an adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. in this study, erythrosine dye removal from an aquatic environment using natural absorbents, namely sorghum and ziziphus nummular...
Investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (LHR) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].The engine had different operating conditions...
In order to study the effects of nitrogen application rate and timing on grain yield, phyllochron and leaf appearance rate of corn (Zea mays L.), an experiment was conducted as split plot based on randomized complete block design with three replications at the Research Farm of University of Mohaghegh Ardabili, Ardabil, Iran during 2009 growing season. Nitrogen rates were arranged in main plot w...
This paper describes the method used in the design of a 26 million transistors chip at BULL to verify the timing performance using the hierarchical timing analysis tool HiTas as well as the interactive path browser Xtas. Those tools have been designed at UPMC and are now commercialized by AVERTEC. The complexity is handled by partitioning the analysis according to the hierarchical partitioning ...
We discuss the di erent ways of de ning channel capacity for certain types of illicit communication channels. We also correct some errors from the literature, o er new proofs of some historical results, and give bounds for channel capacity. Special function techniques are employed to express the results in closed form. We conclude with examples.
