A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...

Introduction: The most important change in medical education is a shift from didactic teacher-centered and subject-based teaching to the use of interactive, problem-based, student-centered learning. Student-centered approach is a teaching approach t that encompasses replacing lectures with active learning, integrating self-paced learning programs and cooperative group situations, ultimately hol...

Background: Study habits and skills are very important particularly in medical school which is characterized by heavy workload, heavy time commitments, and high stakes assessments. Students’ approach to learning, which includes study habits, has an important impact on both the excellence of the learning and their academic success. The aim of this study was to evaluate the study habits of Shiraz...

conclusion with thorough technical knowledge and an adequate learning curve, pra could serve as the surgeon’s preferred surgical approach to the adrenal gland within the confines of its selection criteria. background since the early 1990s, endoscopic adrenalectomy has become the gold standard surgical approach for the adrenal gland. also, lateral transperitoneal adrenalectomy (lta) which is the...

considering the essential role that product development plays in fast- growing firms learning how to perform its activities can be highly valued, whereas product development activities are per se a proper context for knowledge acquisition. in this study, the narrative approach and the technique of deep and targeted interviews have been used to narrate the stories expressed by nine of the sales ...

In this paper, a novel approach proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). As the number of sensors used to measure modal data is normally limited and usually are less than the number of DOFs in the finite element model, the model reduction approach should be used to match with incomplete measured mode shapes. The second-order a...
