introduction: one of the types of hospital management information systems is decision support information system (dsis). this system uses decision-making models and databases for preparing specific information to support their semi-structured or unstructured decisions. the present study aimed to design a decision dsis model for board of trustees of ayatollah kashani hospital, shahrekord, iran. ...

In the water column, planktonic copepods encounter small-scale hydrodynamic disturbances generated by fellow zooplankters. Our question is whether or not the copepods can distinguish between hydrodynamic disturbances created by predators, prey, conspecifics and/or mates. We used a Schlieren optical system with a density gradient in the water volume and filmed at 48 frames per second to record t...

In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...

VSIPL and OpenMP are two open standards for portable high performance computing. VSIPL delivers optimized single processor performance while OpenMP provides a low overhead mechanism for executing thread based parallelism on shared memory systems. Image processing is one of the main areas where VSIPL and OpenMP can have a large impact. Currently, a large fraction of image processing applications...

We use a two-temperature hydrodynamical formulation to determine the temperature and density structures of the post-shock accretion flows in magnetic cataclysmic variables (mCVs) and calculate the corresponding X-ray spectra. The effects of twotemperature flows are significant for systems with a massive white dwarf and a strong white-dwarf magnetic field. Our calculations show that two-temperat...

This paper presents a new attainability technique based on a polyhedral approach for hybrid systems. The main aim of the proposed technique is to obtain a robust-control closed loop system with attainable behavior under all possible and allowable disturbances. Moreover, and in contrast to existed approaches, this technique considers a new switching mechanism that allows the exploration of all d...

The regional waters in Singapore Strait are characterized by complex hydrodynamic phenomena as a result of the combined effect of three large water bodies viz. the South China Sea, the Andaman Sea, and the Java Sea. This leads to anomalies in water levels and generates residual currents. Numerical hydrodynamic models are generally used for predicting water levels in the ocean and seas. But thei...

In the information age, the speed of producing and supplying valuable information is considered as one of the keys to success in the organizations and institutes.The major objective of this study was to investigate and specify the effective factors in evaluating the BI systems with an emphasis on the integrity of organizational resources. First, five factors were determined as the major factors...

The role played by the attainable set of a differential inclusion, in the study of dynamic control systems and fuzzy differential equations, is widely acknowledged. A procedure for estimating the attainable set is rather complicated compared to the numerical methods for differential equations. This article addresses an alternative approach, based on an optimal control tool, to obtain a descript...
