water quality prediction is a valuable tool for pollutant control in aquatic environments. a river system is selected and one-dimensional flow is assumed for the simulation of pollutant transport in this paper. advective and diffusive terms of transport equation are considered separately. different functions of advective transport are proposed and applied for a specified velocity on the discret...

objective: preterm infants are prone to intraventricular hemorrhage. they may suffer from significant morbidity and mortality particularly in those with high-grade hemorrhage. our objective was to determine the incidence of intraventricular hemorrhage in premature infants transported to a tertiary center compared with those delivered at the level iii facility.  methods: we evaluated all prematu...

the objective of this study was to review the literature on sperm transport in the mare. during this process the sperm cells must reach the oviducts in order to fertilize the oocyte, but before reaching this site it must go through the uterus that is a hostile environment at this moment since there is an inflammatory reaction in this location that aims to eliminate excess spermatozoa and bacter...

– One of the important applications of robots is in material handling and transport of various shaped objects. In cases where an object cannot be directly grasped by the robot gripper, and must be carried by a hook, it may be subject to undesirable swings during transport. This paper presents an analytical method for minimizing the oscillation of a suspended object during transport. This method...

Sedimentation is one of the most important problems in harbors that results in considerable economic costs. Harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. In the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...

This paper presents application of an improved Harmony Search (HS) technique and Charged System Search algorithm (CSS) to estimate transport energy demand in Iran, based on socio-economic indicators. The models are developed in two forms (exponential and linear) and applied to forecast transport energy demand in Iran. These models are developed to estimate the future energy demands based on pop...

With the modern development and increasing competitiveness of air transport business processes, the management of knowledge is essential most especially for air transport managers. This controls compounded phases of the organization which begins with the fabrication of organisational strategy towards value creation and improving customers` experience. This study was to explore the review on the...

urbanization development followed by increase in travel demand in recent years made some problems for cities such as traffic, lack of suitable parking, environmental issues, economic and social etc. meanwhile, public transport, especially bus services are very important in the development of urban functions thus, paying attention to different aspects of the transport in order to increase its ef...
