This paper presents a new technique for model order reduction (MOR) of discrete systems with the advantage of selecting some of the desired frequencies. The proposed technique is achieved using the Artificial Neural Network (ANN) prediction. The ANN is implemented for predicting the unknown elements of the reduced order model while selecting the desired frequencies. Prediction of the ANN architecture is based on minimizing the cost FUNCTION obtained by the difference between the actual and desired system behaviour. The proposed ANN-based model order reduction method is compared to recently published work of MOR techniques. Simulation results verify the validity of the new MOR technique.

Some fuzzy multicriteria methods have recently been developed by using type-2 fuzzy sets. Fuzzy TOPSIS is one of these methods. While these need excessive arithmetic operations with respect to type-1's, they can handle the uncertainty in defining membership functions. We modified Buckley's fuzzy AHP method by using type-2 fuzzy sets.

This paper presents fuzzy multi attribute valuation of new software projects in banking industry by balanced score card based on the fuzzy TOPSIS model which includes fuzzy real option. Balanced scorecard method is used to determine the decision criteria by applying survey to managers. The economic side of the evaluation is dynamic and risky in nature in software development projects. Fuzzy real options method is used for surmounting these risky situations. Hence the evaluation of the software development projects has many attributes to investigate;fuzzy TOPSIS method based fuzzy real options method is offered in this paper. There are three software projects to be evaluated and investment ranking will be made according to the result of the method offered in this paper.

Pay structure is the ordering of pay rates for jobs or groups of jobs within an organization and plays an important role in the employment relationships affecting the efficiency of an organization. Design of a pay structure is a complex process requiring the evaluation many factors including both quantitative and qualitative data. Grey Relations Analysis (GRA) a useful mathematical tool for dealing with uncertainty and system analysis with limited information is introduced for creating a pay structure. Fuzzy Analytical Hierarchy Process (FAHP) is also used to determine the factor weights of payment types by pair-wise comparisons. The hypothetical case study shows the applicability of the model.

A new covert channel over the RTP protocol is designed and implemented by modifying the timestamp value in the RTP header. Due to the high frequency of RTP packets, the covert channel has a high bit-rate, theoretically up to 350 bps. The broad use of RTP for multimedia applications such as VoIP, provides abundant opportunities to such a covert channel to exist. By using the RTP header, many of the challenges present for covert channels using the RTP payload are avoided. A reference implementation of this covert channel is presented. Bit-rates of up to 325 bps were observed. The channel is very difficult to detect due to expected variations in the timestamp field and the flexible nature of RTP.

This paper investigates the stability properties of linear T-S fuzzy delayed switched systems with time-varying perturbation. Based on single Lyapunov and multiple Lyapunov methods, respectively, we present the sufficient conditions guaranteeing uniformly asymptotic stability for the T-S fuzzy switched systems under proper switching rules.

In this work, genetic algorithms (GA) have been applied to optimise an interplanetary trajectory of a spacecraft. The desired trajectory visits Jupiter, after performing a gravitational assistance in planet Mars. The GA tunes a set of parameters of the trajectory in order to achieve the mission purpose while satisfying the constraints and minimizing the fuel budget. Due to the complexity of the implemented models and the lack of analytical solutions, an alternative non-traditional algorithm provided by soft-computing techniques such as GA is necessary to achieve an optimum solution. A variable mutation rate has been implemented that broadens the search area whenever the population becomes uniform. The results are satisfactory as the fuel is reduced at all the different stages of the mission, and have been compared to an optimal Hohmann transfer.

The rough and accurate measures of rough functional dependency are proposed in this paper in order to find potential and interesting patterns for rough relational database. The approximate measure of functional dependency for classical relational database and its properties are reviewed. Then the rough and accurate measures of rough functional dependency are introduced. Moreover, their formalization definitions are given, as well as the basic property with which rough and accurate measures satisfied are investigated. The introduction of rough measure theory of rough functional dependency will accelerate the development of knowledge discovery for rough relational database and extend its research field.
