In this paper, we address a strategic planning problem for a three-stage productiondistribution network. The problem under consideration is a singleitem, multi-supplier, multi-producer and multi-distributor production-distribution network with deterministic demand. The objective is to minimize the costs associated with production, transportation and inventory as well as capacity expansion costs...

in order to study the effects of drought stress and organic fertilizers (compost and vermicompost) on some physiological and biochemical characteristics of borage, an experiment with complete randomized block design in split plot arrangement with three replications was conducted in zabol university, zabol, iran. the treatments included 3 levels of stress as a witness or 100% of field capacity, ...

High-level programming and programmable data paths are two key capabilities of software-defined networking (SDN). A fundamental problem linking these two capabilities is whether a given high-level SDN program can be realized onto a given low-level SDN datapath structure. Considering all highlevel programs that can be realized onto a given datapath as the programming capacity of the datapath, we...

The Wilson-Cowan equations were originally proposed to describe the low-level dynamics of neural populations (Wilson&Cowan 1972). These equations have been extensively used in modelling the oscillations of cortical activity (Cowan et al. 2016). However, due to their low-level nature, very few works have attempted connections to higher level psychophysics (Herzog et al. 2003, Hermens et al. 2005...

Most railways use fixed block technology, which could be replaced with moving technology associated high cost. It is therefore interesting to gradually upgrade the signalling system exploiting hybrid technologies. This paper aims investigate impact on capacity of various systems (including and technology) using a microscopic simulation tool under scheduled (static) conditions without considerin...

purpose: military personnel are expected to maintain the highest possible level of physical   fitness to do their duties. several factors including body composition and body mass index   affect the level of their physical preparedness. the current study was designed to investigate   the effect of body composition and body mass index in the level of physical preparedness of   iranian military pe...
