In this paper, after a literature review, studies will be concentrated on standard deviation of invasive weedoptimization's normal distribution function which is used for distributing seeds of each weed over the search space. Although invasive weed optimization is a great algorithm to solve real world practical optimization problems but there is a serious drawback in distributing the seeds over the...
Several widely used model optimization techniques such as, for instance, genetic algorithms, exploit on intelligent test of different input variables configurations. Such variables are fed to an arbitrary model and their effect is evaluated in terms of the output variables, in order to identify their optimal values according to some predetermined criteria. Unfortunately some models concern real world...
Overshoot, settling and rise time define the timing parameters of a control system. The main challenge is to attempt to reduce these parameters to achieve good control performances. The target is to obtain the optimal timing values. In this paper, three different approaches are presented to improve the control performances of second order control systems. The first approach is related to the design...
Evaluating learners in terms of collaboration capabilities in a collaborative e-learning session can be quantified based on several parameters. These parameters include learner's contribution in the collaborative e-learning session. They also include learner's collaboration history in collaborative e-learning sessions and the collaboration capabilities of the group in which he participates. These...
This paper presents an automatic approach for emotion recognition from a bimodal system based on facial expressions and physiological signals. The information fusion is to combine information from both modalities. We tested two approaches, one based on mutual information which allows the selection of relevant information, the second approach is based on principal component analysis that allows the...
We present a memetic algorithm for program safety properties verification. This problem is expressed by means of Reach ability of some erroneous location L in the program. We use a new method for program modeling: A Separation Modeling Approach: ASMA, in which programs are represented by two components: Data Model DM, and Control Model CM. The erroneous location is represented by its "Location...
Most statistical methods do not perfectly conform to real cases of cyber crimes. Consequently, using statistical methods to analyze intrusion logs in order to present evidentiary values in courts of law are often refuted as baseless and inadmissible evidences regardless of the input spent to generate the reports and whether the reports are well-grounded evidences or not. Sometimes, complainants are...
In this paper, a new formulation of the Electrical Capacitance Tomography (ECT) problem for real-time image reconstruction of the multiphase flow fluid passing through a given section of a pipeline is presented. The suggested Regularized Constrained Gauss-Newton (RCGN) algorithm determines the dielectric distribution of the internal fluid by solving the inverse and forward problems on the data captured...
