A computer model for prediction and analysis of an oil-flooded single screw compressor performance is developed. The model includes suction preheat, pressuri ~~.tion of the gas in the control volume during the suction closure process, flowage of gas and oil mixture through discharge port, leakage of gas and oil. It considers the effect of oil-injection rate, clearances and length of leaka~e pat...
abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...
this study considers the level of increase in customer satisfaction by supplying the variant customer requirements with respect to organizational restrictions. in this regard, anp, qfd and bgp techniques are used in a fuzzy set and a model is proposed in order to help the organization optimize the multi-objective decision-making process. the prioritization of technical attributes is the result ...
some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
This paper criticizes the model and the new definition for osmotic pressure given by Parsafar et al. [J. Sci. I. R. Iran, Vol. 10, No. 4, 233 (1999)]. The model is a closed system containing 1 kg of solvent plus m mole of solute at constant temperature and under pressure P0 + ? where P0 is the standard pressure and ? is the osmotic pressure of the corresponding m molal solution. While the total...
the relationship between initial population density of rice white tip nematode (aphelenchoides besseyi) and yield was examined on oryzae sativa cv. alikazemi. experiments were conducted in greenhouse, micro-plot and field conditions. seinhorst’s model was used to describe the relationship between nematode population density and crop yield. the parameters of the model, minimum yield (m), constan...
For maneuvering target tracking problem, interacting multiple model (IMM) algorithm performs better than single model algorithm, however, it also has some shortcomings. This study is devoted to propose a high accurate IMM algorithm. An improved IMM algorithm, named Switched IMM(S-IMM), is proposed. The S-IMM algorithm consists of two independent IMM filters with different model sets, CV(constan...
The N-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. The quantum theoretical calculations for two crystal structures of N-(2-benzoyl-phenyl) oxalyl (compounds I and II) were performed by Density Functional Theory (B3LYP method and 6-311+G* basis set). From the optimized structures, geometric paramet...
Explosion occurs mainly due to unforeseen factors, such as terrorist attacks or performance disruption leading to explosion in facilities and infrastructure caused by fatigue and non-compliance with regulations. Considering the special status of reinforced concrete structures in the construction industry and the extensive usage of the lateral load-bearing system of flexural frames, this researc...
We have used a simple ionic potential to simulate the melting of KCI pseudo-infinite crystal. Two MD simulations, one with constant Volume and the other with constant pressure condition are performed. These results are compared with the previous micro-sample simulation results. In the constant volume simulation the melting temperature increase substantially with increasing pressure. A method fo...
