The problem of determining the sequence of a set of jobs with the objective function of minimizing the maximum earliness and tardiness in one machine is studied. Production systems like JIT are one of the many applications of the problem. This problem is studied in special cases and their optimal solutions are introduced with simple orders. In general, some effective conditions for neig...

abstract   introduction: balance is one of the most important contexts in ageing. improving balance in middle age can prevent falling down in elderly which impose the financial and mental costs to society. imbalance between dominant and non-dominant leg can lead to some problems. that’s way; studying effects of similar exercise on dominant and non-dominant legs of body can prevent problems caus...

A new solution is proposed to decompose a curve into arcs and straight line segments in O(n log n) time. It is a combined solution based on arc detection [1] and dominant point detection [2] to strengthen the quality of the segmentation results. Experimental results show the fastness of the proposed method.

On the basis of 1H and 13C NMR spectroscopy studies, the proportion of pyranose and furanose forms of 6-deoxyheptoses in water solution was determined. Water solution of 6-deoxyheptoses contains all possible furanose and pyranose forms (except 6-deoxy-gluco-heptose for which only pyranose was found), although pyranose is dominant.

Performance analysis calculations, for models of any complexity, require a distributed computation effort that can easily occupy a large compute cluster for many days. Producing a simple steady-state measure involves an enormous dominant eigenvector calculation, with even modest performance models having upwards of 10 variables. Computations such as passage-time analysis are an order of magnitu...

The explicit SPIKE algorithm applies to narrow banded linear systems which are strictly diagonally dominant by rows. The parallel bottleneck is the solution of the so-called reduced system which is block tridiagonal and strictly diagonally dominant by rows. The reduced system can be solved iteratively using the truncated reduced system matrix as a preconditioner. In this paper we derive a tight...
