Abstract: The way in which the displaying of the web pages is done within a search is not a mystery. It involves applied math and good computer science knowledge for the right implementation. This relation involves vectors, matrixes and other mathematical notations. The PageRank vector needs to be calculated, that implies calculations for a stationary distribution, stochastic matrix. The matrices hold the link structure and the guidance of the web surfer. As links are added every day, and the number of websites goes beyond billions, the modification of the web link's structure in the web affects the PageRank..........

Abstract: To improve the efficiency of multi-robot formation control, a new formation control algorithm based on leader-follower optimized by the immune genetic algorithm (IGA) is put forward in this paper. Firstly, the formation control is realized by leader-follower algorithm. Then, the proportion coefficients k1, k2 in leaderfollower is optimized by the immune genetic algorithm. Finally, the optimized proportion coefficients k1 and k2 is used in the leader-follower algorithm to finish the multi-robot formation control. Compared with other three formation control algorithms (i.e. GA, simple leader-follower algorithm, behavior algorithm).........

Title : Analysis of the Waveform of the Acoustic Emission Signal via Analogue Modulations with Neural Networks
Country : Brazil
Authors : Orlando Gea || Luiz P. Calôba

Abstract: The acoustic emission (AE) technique is a non-destructive testing technique applied to pressurized rigid pipelines in order to identify metallurgical discontinuities. This study analyses the dynamic behavior of the propagation of discontinuities in cracks via AE, in the following propagation classes: no propagation (NP), stable propagation (SP), and unstable propagation (UP). The methodology involves applying the concept of modulation of analogue signals, which are used in signal transmission in telecommunications, for the development of a neural network in order to determine new parameters for the AE waveform. The classification of AE signals into propagation classes occurs..............

Abstract: The significant of multi spectral band resolution is explored towards selection of feature coefficients based on its energy density. Toward the feature representiaon in transformed domain, multi wavelet transformations were used for finer spectral representation. However, due to a large feature count these features are not optimal under low resource computing system. In the recognition units, running with low resources a new coding approach of feature selection, considering the band spectral density is developed. The effective selection of feature element, based on its spectral density achieve two objective of pattern recognition, the feature coefficient representiaon is minimized, hence leading to lower resource requirement, and dominant feature representation, resulting in higher retrieval performance.

Keywords: Spectral features, spectral density feature selection, pattern recognition, retrieval accuracy.

Abstract: The Data sharing is an important functionality in cloud storage. We describe new public key crypto systems which produce constant-size cipher texts such that efficient delegation of decryption rights for any set of cipher texts are possible. The novelty is that one can aggregate any set of secret keys and make them as compact as a single key, but encompassing the power of all the keys being aggregated. Ensuring the security of cloud computing is second major factor and dealing with because of service availability failure the single cloud providers demonstrated less famous failure and possibility malicious insiders in the single cloud..............

Abstract: Acceptability of indigenous software is always low in most of the African countries especially in Nigeria. This paper then study and presents the results on the assessment of the approaches used in indigenous software development products. The study involved ICT firms that specialized in software development and educational institutions who were part of major stakeholders as well as users of software packages. The primary tool for data collection was questionnaire, which was used to elicit information from software developers on the various approaches adopted in their operations. This was also complemented with information from secondary sources...............

Abstract: The paper presents an innovative approach to mathematical modeling of complex systems "human-dynamical process". The approach is based on the theory of measurement and utility theory and permits inclusion of human preferences in the objective function. The objective utility function is constructed by recurrent stochastic procedure which represents machine learning based on the human preferences. The approach is demonstrated by two case studies, portfolio allocation with Wiener process and portfolio allocation in the case of financial process with colored noise..............

Abstract: Trying to detecting a face from any photo is big problem and got these days a focusing because of it importance, in face recognition system,face detection in one of the basic components. A lot of troubles are there to be solved in order to create a successful face detection algorithm. The skin of face has its properties in color domain and also a texture which may help in the algorithm for detecting faces because of its ability to find skins from photo. Here we are going to create a new algorithm for human face detection depending on skin color tone specially YCbCr color tone as an approach to slice the photo into parts..............

Abstract: In spatial tasks, the use of cognitive aids reduce mental load and therefore being appealing to trainers and trainees. However, these aids can act as shortcuts and prevents the trainees from active exploration which is necessary to perform the task independently in non-supervised environment. In this paper we used adaptive repetition as control strategy to explore the 3D- Virtual Learning environments. The proposed approach enables the trainee to get the benefits of cognitive support while at the same time he is actively involved in the learning process. Experimental results show the effectiveness of the proposed approach.
