Abstract Cloud computing, which is distributed, stored and managed, drawing attention as data generation storage volumes increase. In addition, research on green increases energy efficiency, also widely studied. An index constructed to retrieve huge dataset efficiently, the layer-based indexing methods are used for efficient query processing. These construct a list of layers, so that only one l...

Utilization of fossil fuel for supplying of requires energy of desalination systems is common. On the other hand, solar energy is one of the high-grade energies in the world that can be found specifically in hot weather places. Therefore, utilization of solar energy for operation of desalination systems will reduce greenhouse gases and is a good alternative way. Common exergy analysis method (s...

For most branching algorithms in Boolean logic “branching” means “variable-wise branching”. We present the apparently novel technique of clause-wise branching, which is used to solve the ALLSAT problem for arbitrary Boolean functions in CNF format. Specifically, it converts a CNF into an orthogonal DNF, i.e. into an exclusive sum of products. Our method is enhanced by two ingredients: The use o...

This paper describes a comparison of some numerical methods for solving the advection-diffusion (AD) equation which may be used to describe transport of a pollutant. The one-dimensional advection-diffusion equation is solved by using cubic splines (the natural cubic spline and a ”special” AD cubic spline) to estimate first and second derivatives, and also by solving the same problem using two s...

In this work we extend the trajectory piece-wise linear (TPWL) approximation of large, non-linear and input-affine dynamical systems to non-linear systems with non-linear input operators. The new technique is called the trajectory piece-wise quasi-linear (TPWQ) approximation. We explain the motivation for this technique in light of previously reported under-performance of the TPWL method and sh...

A method for automatic 2D image registration based on combining multiple row-wise and column-wise dynamic programming (DP) processes is presented. Combination is performed by means of a parametric transform (either rigid or non-rigid) which is estimated from the output of the dynamic programming processes. The method performs particularly well on histopathology images as dynamic programming is ...
