An Approximate Minimum Degree Ordering Algorithm
An Approximate Minimum Degree ordering algorithm (AMD) for preordering a symmetric sparse matrix prior to numerical factorization is presented. We use techniques based on the quotient graph for matrix factorization that allow us to obtain computationally cheap bounds for the minimum degree. We show that these bounds are often equal to the actual degree. The resulting algorithm is typically much...
متن کاملAlgorithm 8xx: AMD, an approximate minimum degree ordering algorithm
AMD is a set of routines for permuting sparse matrices prior to numerical factorization, using the approximate minimum degree ordering algorithm. There are versions written in both C and Fortran 77. A MATLAB interface is included.
متن کاملAlgebraic Observability Analysis of Electrical Network with Symbolic Computation: Application on MYRTE Electrical Power Plant
We present a symbolic algebraic electrical system analysis method . A single-phase model is applied to a renewable electrical power plant. Once the system relations established, algorithms are applied, calculating the Groëbner bases for determining the system observability. Parallel programming is used in order to manage the number of relations and to decrease the time computing. A cost sensor ...
متن کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
analysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
