Geoscientists have become increasingly dependent on digital elevation models (DEMs) to delineate and measure landforms and landscapes. However, the DEM grid cell size available may not be the optimum resolution; this can mask subtle changes in measurements and lead to erroneous results. This paper presents a standardized statistical technique (i.e. statistical process control charts (SPCC)) for...

The width of an interconnect line affects the total power consumed by a circuit. A trade off exists between the dynamic power and the short-circuit power dissipated in inductive interconnect. The optimum line width that minimizes the total transient power dissipation is determined in this paper. A closed form solution for the optimum width with an error less than 5% is presented. For a specific...

The optimum Runge-Kutta method of a particular order is the one whose truncation error is a minimum. Various measures of the size of the truncation error are considered. The optimum method is practically independent of the measure being used. Moreover, among methods of the same order which one might consider using the difference in size of the estimated error is not more than a factor of 2 or 3...

Social interactions among individuals are abundant both in natural and domestic populations. Such social interactions cause phenotypes of individuals to depend on genes carried by other individuals, a phenomenon known as indirect genetic effects (IGE). Because IGEs have drastic effects on the rate and direction of response to selection, knowledge of their magnitude and relationship to direct ge...

by shouldering the burden of a big chunk of global production, and giving shelter to half of the world’s population, currently cities play an important role in national economies. benefits of agglomeration in cities have played a major role in the process of economic development of different countries, however, the expansion of urbanization has produced some problems including environmental and...

the main objective of the present study was qualitative assessment of golden gray mullet stocks by using indicators of overfishing in iranian waters of the caspian sea during a long period (1991-2011). three fisheries indicators in catch were: 1. percentage of mature fish, with 100% as target; 2. percent of specimens with optimum length, with 100% as target; and 3. percentage of mega-spawners, ...

oil production optimization is one of the main targets of reservoir management. smart well technology gives the ability of real time oil production optimization. although this technology has many advantages; optimum adjustment or sizing of corresponding valves is still an issue to be solved. in this research, optimum port sizing of inflow control devices (icds) which are passive control valves ...

We consider the problem of testing uniformity on high-dimensional unit spheres. We are primarily interested in nonnull issues. We show that rotationally symmetric alternatives lead to two Local Asymptotic Normality (LAN) structures. The first one is for fixed modal location θ and allows to derive locally asymptotically most powerful tests under specified θ . The second one, that addresses the F...
