Abstract: An ambition to avoid deadlock states occurring in simulation models of railway station operation requires an application of methods from resource allocation systems. Because of complexity of the underlying system, Banker’s algorithm has been chosen. To test its applicability, a coloured Petri net model of a simple railway station operation was constructed and the algorithm implemented...

Sensor nodes, charged with battery power and capable of wireless communications, are distributed around to survey the environments and to send the needed data to the base station. The limited energy resources of sensor nodes are consumed in computation and especially in communication. To reduce power consumption for the sensor network, this paper presents a new data gathering scheme based on th...

Mixed-model assembly line (MMAL) is a type of assembly line where several distinct models of a product are assembled. MMAL is applied in many industrial environments today because of its greater variety in demand. This paper considers the objective of minimizing the work overload (i.e., the line balancing problem) and station-to-station product flows. Generally, transportation time between stat...

In mediastinal dissection through a right thoracotomy, the definition of station 2 is arbitrary because no anatomical landmark indicates the line drawn tangentially to the upper margin of the aortic arch. We have developed a technique to localize it by evaluating the distance between the upper aortic arch and the azygos vein on a CT scan. This distance located intraoperatively above the azygos ...

air pollutants from iron and steel making operations have historically been an environmental concern. the factory located at ahwaz, iran, has two production lines namely, 630 and 650, which produce iron parallel edge. the objective of the study is to determine indoor respiratory particulate matter (rpm) and feo concentrations and their comparison with niosh standards. this is a cross–sectiona...

In [1] a rate-compatible joint network-channel code (JNCC) for the two-way relay channel was proposed which can be applied for the cooperative uplink and downlink in a mobile communication system with the help of a relay. We assume the system model of [1] and present an improved JNCC which is based on the decode-and-forward scheme of [2]. In [2] a coding scheme was proposed which does not consi...
