Although the Lagrangian method is a powerful dual search approach in integer programming, it often fails to identify an optimal solution of the primal problem. The p-th power Lagrangian method developed in this paper ooers a success guarantee for the dual search in generating an optimal solution of the primal integer programming problem in an equivalent setting via two key transformations. One ...
اندازه گیری سطح مقطع موثر برخورد نوترون در واکنش(n,?)بامختصات رآکتور تهران جهت محاسبه اکتیویته رادیوایزوتوپ ساماریم تحویلی به مراکز بیمارستانی امری کاملا ضروری می باشد.جهت محاسبه اکتیواسیون با نوترونهای حرارتی و فوق حرارتی بطور همزمان از روش اختلاف کادمیم استفاده می شود.برای پرتودهی نمونه در شار نوترونی جهت جداکردن اکتیواسیون حرارتی و فوق حرارتی، پولک (نمونه) در پوششی از کادمیوم بضخامت 5/0 تا 5...
In this part, a FPGA based implementation of Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) as applied to a single-phase A.C. Chopper using Generalized Hopfield Neural Network (GHNN) is designed and implemented. The objective of this part is to eliminate 5 th , 7 th , 11 th and 13 th order harmonics in the output voltage waveform of the single-phase A.C. Chopper while retaining ...
The ABS methods, introduced by Abaffy, Broyden and Spedicato, aredirect iteration methods for solving a linear system where the$i$-th iteration satisfies the first $i$ equations, therefore a system of $m$ equations is solved in at most $m$ steps. In thispaper, we introduce a class of ABS-type methods for solving a full rowrank linear equations, w...
INTRODUCTION Autoantibodies to the Th/To antigen have been described in systemic sclerosis (SSc) and several proteins of the macromolecular Th/To complex have been reported to react with anti-Th/To antibodies. However, anti-Th/To has not been clinically utilized due to unavailability of commercial tests. The objective of the present study is to evaluate the newly developed ELISA and chemilumine...
The Voynich manuscript (VMS) is the book dated as 15 th-16 th century, written using specific and smart coding methods. This article describes the methods how it was analyzed and how coding keys were found. It is also shows the VMS author's method of coding.
Over the last decades, determination of ages in monazite using Electron Probe Microanalysis (EPMA) has progressed to the point that it is now considered as a routine procedure within several laboratories worldwide [1,2]. Nevertheless, the typical age errors of individual electron probe spots reported in the literature are an order of magnitude larger than attainable by Secondary Ion Mass Spectr...
This review focuses on the application of Th as a proxy for the flux of particulate organic carbon (POC) from the surface ocean. The use of this Th flux approach requires determination of both the Th activity distribution (used to calculate Th fluxes), and an estimate of the C/Th ratio on sinking particles to empirically derive C fluxes. Observations have shown that in general C/Th decreases wi...
