occurrence of chaotic behaviors because of fluctuations creation and their intensified transfer along the chain is one of the main causes of inefficiency of material requirements planning (mrp) based supply chains. one of the reasons of the inefficiency is the lumpiness phenomenon. through this phenomenon, some parts have an irregular production schedule, with nothing produced in some periods a...

it is fair to say that the man by including agricultural, industrial activities and exploitation-of natural resources in his survival agenda is the most responsible of all for environmental changes. fundamentall development in various parts of a watershed is unavoidable and sometimes necessary. in recent years, large number of environmentally improper developments including new town development...

OBJECTIVE This study was performed in order to determine if mathematical modeling of the canine teeth in dogs could be utilized to provide an accurate and reliable estimation of crown surface area that could be used in both a research and a clinical setting. MATERIALS AND METHODS Actual surface area (aSA) calculations for 32 stone dies of clinical crown preparations were acquired utilizing a ...

To investigate walking we perform experimental studies on animals in parallel with software and hardware simulations of the control structures and the body to be controlled. In this paper, we will first describe the basic behavioral properties of hexapod walking, as the are known from stick insects. Then we describe a simple neural network called Walknet which exemplifies these properties and a...

Several region connection calculi have been proposed for use in Qualitative Spatial Reasoning (QSR). Perhaps the most well-known model is RCC-8, which uses a 9-Intersection framework to identify the spatial relation between two regions. The calculation of the 9-Intersection matrix is particularly computationintensive in 3D. Herein we show that 9-Intersection calculations can be replaced with 2-...

The idea behind grid computing is to make multiple machines that may be in different physical locations, behave like they are one large virtual machine. In grid computing, the total work load is distributed among many computers which are linked together through some kind of local or global network topology. There is no restriction of work it could be of any type like mathematical calculations o...
