The ability of the adaptive immune system to discriminate safely between foreign and self molecules is a fundamental ingredient to everyday survival of higher vertebrates (such as ourselves). Unlike innate immune responses, which happen in all kinds of organisms, responses of the adaptive immune system are highly speci c to the target which induced their activation. Until now it is not quite cl...
In this study, a mathematical model is developed based on algebraic equations which is capable of generating artificially normal events of electrocardiogram (ECG) signals such as P-wave, QRS complex, and T-wave. This model can also be implemented for the simulation of abnormal phenomena of electrocardiographic signals such as ST-segment episodes (i.e. depression, elevation, and sloped ascending...
Introduction: Hospital administrators have always faced the challenge of providing the best possible health services in a resource-limited environment. The patient flow throughout the hospital is affected by lack of the capacities that can lead to bed-blocking among the hospital units. In this research, the patient flow in the hospital is modeled as an open queueing network with blocking. Then,...
It is still an open question in parallel discrete event simulation what conditions influence the performance of parallel simulation paradigms. We have developed a simulation environment based on asynchronous cellular automata that facilitates basic research into the concepts of discrete event simulation and parallel discrete event simulation, such as the Time Warp paradigm. We address the trans...

Studies of the structure of atoms and ions (ultracold to relativistic included) as well as their twobody interactions with photons, electrons and other particles require accurate methods for the description of such objects. In order to obtain accurate values of atomic quantities it is necessary to account for relativistic and correlation effects. Relativistic effects may be taken into account a...
large impervious surfaces and man-made waterways are the characteristic of urban area. increasing urbanization and rapid growth of cities in recent decades towards the upstream watershed, has been severely affected on rainfall-runoff processes in urban area. therefore, to computer models in order to illustrate these processes the proper design or assessment of urban drainage systems has special...
Template matching is a widely used technique in many of image processing and machine vision applications. In this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to Rotation, Scale, Translation and Brightness (RSTB) changes. For this purpose, we adopt the idea of ring projection transform (RPT) of image. In the proposed algorithm, two novel s...
In every production plant, it is necessary to have an estimation of production level. Sometimes there are many parameters affective in this estimation. In this paper, it tried to find an appropriate estimation of production level for an industrial factory called Barez in an uncertain environment. We have considered a part of production line, which has different production time for different kin...
Introduction: Many simulation studies have been conducted in the hospitals and first in the emergency departments to increase the productivity. The first issue in the field of service quality and hence the patient right is “waiting time”. The goal of this study was to reduce patients waiting times, emergency service timing, modeling and improving using discrete event simulation. Methods: This...
