The purpose of this paper is to present an INDEX for evaluation of power network security after terrorist attacks against the network facilities using fuzzy SET theory. In order to achieve this goal, a method based on probability and possibility theory is used. In the first step, by using Bayesian network which is a method based on probability theory, the probability of the attack as well as the risk value caused by terrorist activities against the power network facilities was calculated and the network facilities were ranked according to the level of the risk. In the second step, by employing fuzzy load flow and finding the fuzzy parameters related to network performance, the impact of the loss of each component ranked in the first step on power network was investigated. Finally, having calculated the risk value caused by terrorist attacks against the network facilities, an INDEX was provided for evaluating power network security. Also, in order to validate the effectiveness of the proposed method, security INDEX for a specific network was calculated.

In this paper we present some properties of SET-norm exhaustive SET multi functions and also of atoms and pseudo-atoms of SET multi functions taking values in the family of non-empty subSETs of a commutative semi group with unity.

In this paper we define the Soft SET Product as a product of many soft SETs and afterwards we extend it to the HyperSoft SET. Similarly, the IndetermSoft Product is extended to the IndetermHyperSoft SET. We also present several applications of the Soft SET Product to Fuzzy (and fuzzy-extensions)  Soft SET Product and to IndetermSoft SET and IndetermHyperSoft SET.

Background and objectives: Carpal Tunnel Syndrome (CTS) is the most common mononeuropathy encountered in clinical practice. Conventional electro diagnosis studies have been useful in the diagnosis of this condition. The Terminal Latency INDEX (TLI) is a derived neurophysiological value that adjusts the Distal motor Latency (DL) for the terminal distance and motor nerve Conduction Velocity (CV).Several studies have suggested utility of the median TLI for diagnosis of CTS.The goal of this study is to evaluate prospectively the sensitivity of the median TLI in the diagnosis of CTS and compare it with other electrodiagnosis techniques.Material and Methods: This study was done on 111 patients as CTS group & 62 healthy subject as control group. In all groups five selected tests of electrodiagnosis were done and all of them were compared with TLI sensitivity.Results: The mean TLI was 0.3±0.05 in the CTS group and 0.42±0.03 in the control group. The sensitivity of TLI was 73% The TLI wasn't statistically better than the other tests, but in three cases from the CTS group, the TLI was the only abnormal test.The 7 and 14 cm method had meaningful sensitivity in contrary to other tests.Conclusion: The sensitivity of TLI has no meaningful difference with other routine electro diagnostic tests in diagnosis of CTS.The median TLI is a useful but not more sensitive electrodiagnostic test for CTS.

Introduction: Three methods of OCRA INDEX, Strain INDEX (SI), and ACGIH HAL have been proposed for the assessment of risk factors of upper limb musculoskeletal disorders. Investigating the correlation and consistency of these three methods are of prominence importance in the workplaces. Thus, this study aimed to determine the correlations of the results of the above mentioned methods. Materials and Methods: In this cross-sectional study, a total of 150 tasks were studied in four industries. For each task, a video taping of a full working cycle was prepared and evaluated according to the instructions of each method. The level of risk exposure to musculoskeletal disorders was analyzed with correlation and Kappa agreement coefficient tests using SPSS (version 16) and R software packages.Results: The correlation between the results of risk assessments of OCRA and SI methods for right and left hands were acceptable and equal to 0.751 and 0.726, respectively (p<0.001). Meanwhile, the coefficients of agreement between OCRA and HAL methods for left and right hands were 0.526 and 0.595, respectively.Conclusion: These findings partly confirmed the agreement between the methods of risk assessment. The origin of this partial agreement can be the number and type of variables and their impacts on the final score of the methods.
