سنجش کارایی سازمانهای تولیدی و صنعتی و مقایسه کارایی بین واحدهای آنها از جمله مسائل مهمی است که امروزه در حوزه صنعت مورد توجه قرار گرفته است. در این مقاله از تکنیک تحلیل رابطه خاکستری و تحلیل پوششی دادهها بطور ترکیبی برای ارزیابی تأمینکنندگان در شرکت فراگستر توس استفاده شده است. هدف اصلی این مقاله بررسی نقش شاخصهای نماینده (از میان نهادهها و ستادهها) برای کاربرد در مدل تحلیل پوششی ...
Significance testing for a possible signal in counting experiments centers on the probability that an observed count in a signal region, or one more extreme, could have been produced solely by fluctuations of the background source(s) in that region. Statisticians refer to this probability as a p-value. The traditions for calculating signal significance differ between High Energy Physics (HEP) a...
Abst ract. This pap er pr esents th e applica tion of signal flow gra phs to the det ermination of the exact values of gradient vecto r and hessian matrix for a linear system. It is shown all information about the gradient and hessian is cont ained in the or iginal and adjoint signa l flow graphs at different terminations. To det ermine the gra dient we have to perform two analyses , and t o ge...
The aim of this paper is to present a hybrid group decision model for evaluating flexible manufacturing systems(FMSs), in which the information about attribute weights is completely unknown, and the attribute values take the form of triangular fuzzy numbers. In this proposed methodology, the voting method is adopted to calculate the attribute weights by aggregating the decision-makers’ attitude...
The success of sentence classification often depends on understanding both the syntactic and semantic properties of wordphrases. Recent progress on this task has been based on exploiting the grammatical structure of sentences but often this structure is difficult to parse and noisy. In this paper, we propose a structureindependent ‘Gated Representation Alignment’ (GRA) model that blends a phras...
Primary aldosteronism (PA) is the most frequent cause of secondary hypertension in adults, accounting for 5% to 15% of hypertensive patients, depending on the severity of blood pressure levels.1,2 Patients with PA undergo a higher rate of cardiovascular complications compared with essential hypertensives, and, thus, the screening of hypertensive subgroups of patients with higher prevalence of P...
The general realization algorithm GRA is developed to identify modal parameters of linear multi-degree-of-freedom dynamic systems subjected to measured known arbitrary dynamic loading from known initial conditions. The GRA extends the well known eigensystem realization algorithm ERA based on Hankel matrix decomposition by allowing an arbitrary input signal in the realization algorithm. This gen...
Evaluating the assessing results' rationality for farmland quality (FQ) is usually qualitative and based on farmers and experts' perceptions of soil quality and crop yield. Its quantitative checking still remains difficult and is likely ignored. In this paper, FQ in Xiuwu County, the Northwest Henan Province, China was evaluated by the gray relational analysis (GRA) method and the traditional a...
Quantitative and qualitative fuzzy measures have been proposed to hesitant fuzzy sets 9 (HFSs) from different points. However, few of the existing HFSs fuzzy measures refer to the grey 10 relational analysis (GRA) theory. Actually, the GRA theory is very useful in the fuzzy measure 11 domain, which has been developed for such the intuitionistic fuzzy sets. Therefore, in this paper, 12 we apply ...
AIM The discovery of new natural compounds with pharmacological properties is a field of interest widely growing. Recent literature shows that Brassica vegetables (Cruciferae) possess therapeutic effects particularly ascribed due to their content in glucosinolates, which upon myrosinase hydrolysis release the corresponding isothiocyanates. This study examines the potential neuroprotective and i...
