any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
One of the great enemies of rubber compounds is heat. Heat will cause chemical and physical degradation of vulcanized rubber as well as a considerable loss in its strength. A major source of heat generation in a tire is due to internal friction resulting from the viscoelastic deformation of the tire as it rolls along the road. Another source of heat generation in a tire is due to its contact fr...
With the development of quantitative remote sensing, regional evapotranspiration (ET) modeling based on the feature space has made substantial progresses. Among those feature space based evapotranspiration models, accurate determination of the theoretical dry/wet lines remains a challenging task. This paper reports the development of a new method, named DDTI (Determination of Dry line by Therma...
the task of balancing of assembly lines is well-known in mass production system but this problem is np-hard even for the simple straight line. therefore, utilizing heuristic methods for these problems is totally unquestionable. furthermore, in line with balancing problems, heuristic methods are the foundation of the metaheuristic methods, thus it seems to be necessary to use more efficient heur...
در این پایان نامه انتقال حرارت در مبدل های حرارتی دوار(پیش گرمکنهای هوای دوار) مطالعه و بررسی شده است . معادلات حاکم بر انتقال حرارت در این مبدل، از موازنه انرژی در جزء حجمی از مبدل بدست آمده و یک روش تحلیلی - تقریبی موسوم به heat balance integrated method جهت تعیین توزیع درجه حرارت در بخش های گاز و هوا ارائه شده است . همچنین در این پایان نامه تغییرات خواص فیزیکی گاز، هوا و ماتریس فلزی و همچنین...
Dual scattering channel schemes extend the transmission line matrix numerical method (Johns’ TLM algorithm) in two directions. For one point, transmission line links are replaced by abstract scattering channels in terms of paired distributions (characteristic impedances are thus neither needed, nor in general defined, e.g.). In the second place, non-trivial cell interface scattering is admitted...
