heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

Data fusion is the combination of the results of independent searches on a document collection into one single output result set. It has been shown that this can greatly improve retrieval effectiveness over that of the individual results. This paper compares some major data fusion and system selection techniques by experimenting on TREC ad hoc collections.

BACKGROUND Hemoglobin A1c (HbA1c) measurement is of great value for the diagnosis and monitoring of diabetes. Many manufacturers have developed various experiments to determine the HbA1c concentration. However, the longitudinal use of these tests requires strict quality management. This study aimed to analyze the quality of HbA1c measurement systems in China using six sigma techniques to help i...

The development of a new drug is often compared with finding a needle in a haystack (Kubinyi, 2004). Therefore, rational approaches for drug design began to develop about 30 years ago with the aim to significantly reduce the amount of in vivo animal experiments. With the dramatic increase of computer performance during the last years there has been an increasing interest in virtual screening me...

abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...

“Data Reservoir” is a file sharing facility system which uses parallel streams for huge data transfer on Long Fat Pipe Network. While experimenting Data Reservoir system, we observed that performances of parallel streams disperse a lot, which results in damage on total performance. To equalize throughput of parallel streams, we propose “Dulling Edges of Cooperative Parallel streams(DECP)”. This...
