This paper describes a polynomial-time heuristic for the permutation flow-shop scheduling problem with the criterion of minimizing total completion time. The proposed method consists of two phases: arranging the jobs in priority order and then constructing a sequence. A new ranking method is employed to prioritize the jobs for incorporating into the construction phase of the heuristic. Computat...
OBJECTIVE To determine which multidetector-row helical CT scanning technique provides the best-quality reconstructed 3D images, and to assess differences in image quality according to the levels of the scanning parameters used. MATERIALS AND METHODS Four objects with different surfaces and contours were scanned using multidetector-row helical CT at three detector-row collimations (1.25, 2.50,...
The paper discusses a new technique for the removal of blur in a X-ray caused by uniform linear motion. This method assumes that the linear motion corresponds to an integral number of pixels and is aligned with the horizontal (or vertical) sampling. The proposed approach can be summarized as follows: Given is a gray value vector g, the row of the digitized degraded X-ray . The unknown to be rec...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
A spanning tree of a connected graph is a tree which consists the set of vertices and some or perhaps all of the edges from the connected graph. In this paper, a model for spanning tree transformation of connected graphs into single-row networks, namely Spanning Tree of Connected Graph Modeling (STCGM) will be introduced. Path-Growing Tree-Forming algorithm applied with Vertex-Prioritized is co...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
A field study was conducted on sandy clay loam soil to evaluate the impact of row spacing and N application method on the productivity of maize (Zea mays L.). The experiment was conducted using four row spacings (60 cm spaced single rows, 90 cm spaced double row strips, 90 cm spaced single rows and 135 cm spaced double row strips) and two methods of nitrogen (N) application (broadcast and band ...
Abstract Many heat transfer tubes are distributed on the tube plates of a steam generator that requires periodic inspection by robots. Existing robots usually involved in issues: Robots with manipulators need complicated installation due to their fixed base; mobile suffer from low running efficiency because structural restricts. Since there thousands be checked, task planning is essential guara...
