  • A fuzzy knowledge-based inference system for detecting human skin color   Order a copy of this article
    by Mehdi Neshat, Ghodrat Sepidname 
    Abstract: Abstract: One of the most important applications of intelligent systems in medicine is using expert systems to help with the diagnostic-treatment decision making process. Identification of a human has many various methods that one of the best ways is detecting the type of human skin. The processing speed and having high accuracy play an important role in this way. Designing a new Fuzzy Expert System is aimed at for detecting human skin from other materials intelligently. Skin detection is a challenging problem, because certain factors such as brightness change, a complicated background, and objects with colors similar to that of human skin represent the obstacles thereof. The dataset used in this research was adopted from the UCI accredited database having 245057 records, with each record having four fields. The skin is made up of R, G, and B color space segmentation obtained from the facial images of both genders in different age and racial groups. The results achieved show that this system has managed to detect human skin with 80% accuracy using the help of experts knowledge on human skin detection such as dermatologists and digital image processing experts.

  • Community Detection Using Intelligent Water Drops Optimization Algorithm   Order a copy of this article
    by Iyad Abu Doush, Saba ElMustafa, Ameera Jaradat, Nahed Mansour 
    Abstract: Community structure means the existence of densely connected subgroups in the networks. It is a surprising property that appears in complex and naturally constructed networks. We are proposing a novel heuristic approach to the community detection problem. In this paper, the community detection problem is solved using the intelligent water drop heuristic on a group of real life networks. The proposed heuristic succeeded in grouping the nodes in the network into sets of densely connected subgroups. Our approach uses the modularity value as an optimization criterion. The quality of the resulting division in the network was proven using measures like modularity and NMI. The experimental results verify that our algorithm is highly efficient at discovering quality community structure.

  • An Improved HBA Metaheuristic   Order a copy of this article
    by Bekaddour Fatima, Chikh Amine 
    Abstract: As simple and effective optimization approach, HBA (Homogeneity Based Algorithm) is one of the recent metaheuristics, proposed to minimize the total misclassification cost of data mining approaches. However, one problem is that HBA does not adopt computational complexity of the used data mining technique. This is due to the way objective function is defined. So, in this paper, we have proposed an improved HBA (IHBA), which is utilizing a modified objective function that compute the computational complexity of the used classification method. We also test several clus-tering techniques as HBA parameters tuning, in order to enhance classifiers performance. We have tested IHBA on different benchmarks and the obtained results show the effectiveness of the pro-posed method.

  • Rotation-invariant method for texture matching using model based histograms and GLCM.   Order a copy of this article
    by Izem Hamouchene 
    Abstract: Nowadays, the research is interested in informatics systems that process automatically the information without human intervention. Image is an interesting research area due to the growth of the technologies. Thus, very large data are generated. This represents industrial and economic problem. Texture is one of the important and complex field of image processing. As all surfaces of objects are textured in nature, we have proposed a new texture analysis method. One of the key problem in image processing is the rotation. Therefore, the proposed method is robust against rotation. The goal of this study is to construct a model from each texture. After that, the system classifies the query texture based on the extracted texture models. In this work, we applied a recent and efficient feature extraction method called Rotation Invariant Neighborhood-based Binary Pattern (RINBP). The RINBP method extract relative and invariant patterns from the textured image. The proposed system combines between two parts. First, extract the RINBP model from the texture to describe the local variation of the texture. Second, we apply the GLCM method in order to extract statistical measures from the texture. Thus, efficient combination between the model histogram and statistical measures represents an efficient and robust feature descriptor of the texture. In the experiments, we have used the Brodats album database, which is a reference texture database. Experimental parts illustrates the efficiency and the robustness of the proposed system against rotation.

  • A 0 -1 Bat Algorithm for Cellular Network Optimisation: A Systematic Study on Mapping Techniques   Order a copy of this article
    by Zakaria Abd El Moiz Dahi, Chaker Mezioud, Amer Draa 
    Abstract: Many research efforts are deployed today in order to design techniques that allow continuous metaheuristics to also solve binary problems. However, knowing that no work thoroughly studied these techniques, such a task is still difficult since these techniques are still ambiguous and misunderstood. The Bat Algorithm (BA) is a continuous algorithm that has been recently adapted using one of these techniques. However, that work suffered from several shortfalls. This paper conducts a systematic study in order to investigate the efficiency and usefulness of discretising continuous metaheuristics. This is done by proposing five Binary variants of the BA (BBAs) based on the principal mapping techniques existing in the literature. As problem benchmark, two optimisation problems in cellular networks, the Antenna Positioning Problem (APP) and the Reporting Cell Problem (RCP), are used. The proposed BBAs are evaluated using several types, sizes and complexities of data. Two of the top-ranked algorithms designed to solve the APP and the RCP, the Population-Based Incremental Learning (PBIL) and the Differential Evolution algorithm (DE), are taken as comparison basis. Several statistical tests are conducted as well. Experiments show that the angle modulation and the nearest-integer techniques are the best ones. In addition, results of the evaluation demonstrate that the BBAs based on these techniques still have some shortcomings, but they could outperform the PBIL in 5 out of 13 of the APP instances and achieve results as good as the ones obtained by the DE in 3 out of 12 of the RCP instances.

  • Social Network Analysis: Friendship inferred by chosen courses, Commuting time and Student Performance at University   Order a copy of this article
    by Lionel Khalil, Marie Khair 
    Abstract: Our Social Network Analysis (SNA) evaluates the performance of students taking courses with a group of friends versus students used to take courses alone. We evaluate the probability to be friend by comparing the number of courses shared by students with the probability to be assigned in the same classroom randomly based on curriculum constraints. A minimum of courses taken in common is used as a criterion to identify students belonging to a tribe of friends. The main findings are that students in tribes over perform other students by about half point of GPA, and are dropping and repeating fewer courses. Considering student without friends, we measured the impact of the commuting distance on GPA and drop off rate: students with very low GPA and high drop off are mostly students with significant higher commuting time.

  • Experimental determination of soil electrical parameters for creation of a computer model of a grounding system for lightning protection   Order a copy of this article
    by Rositsa Dimitrova, Marinela Yordanova, Margreta Vasileva, Milena Ivanova 
    Abstract: The paper presents multifactor experimental studies for determining the apparent soil resistivity and the dielectric permittivity depending on the frequency of the electromagnetic field, the multilayered structure, moisture content and density of the soil. The gravimetric method for considering the soil moisture during the experimental researches was chosen. The received experimental results were statistically processed and a mathematical modeling of the controlled parameters was performed considering the specifics of the examined soil. These analytically obtained results of the dependences would contribute to more precise sizing of the grounding systems and could be used for creation of accurate simulation models for study of wave processes in them.
    Keywords: soil electrical parameters; soil resistivity; dielectric permittivity; multilayered soil; gravimetric method; mathematical modelling; grounding system; grounding rod; lightning protection.

  • An approach to Transformation of Data into Knowledge for Power Control in Smart Homes   Order a copy of this article
    by Ivaylo Atanasov, Anastas Nikolov, Evelina Pencheva 
    Abstract: Internet of Things (IoT) encompasses information and networking technologies which allow connected devices gathering data from their environment to exchange information with network applications. The increased number of diverse devices and the variety of multimodal data make interoperability a challenging task. Synthesis of semantic information from raw IoT data enables sharing of common data models between different applications. The paper presents an approach to modeling semantic annotation for power control in smart homes and then converting it to knowledge. The approach includes context aware models as well as a knowledge base describing behavior of an autonomous agent. The context aware models representing remote device management are formalized and verified using the concept of bisimulation. Temporal logic is used for specifying the agent behavior and reasoning about power control of home appliances.
