Jobs scheduling and load balancing functionalities are crucial for best Grid performance and utilization. In this paper, we present a dynamic and adaptive polyhedron topology-aware Grid load balancing method which we called Tun Grid. Its main objective is the extreme decentralization of the scheduling and the load balancing processes at the lowest processing and networking cost. It ensures load balancing through an adaptive local neighborhood propagation strategy of overload. Tun Grid was experimented using the Grid Sim simulator and compared to other methods. Experimental results are presented and discussed.

The goal of the semantic web, also known as a third generation, is to improve the web service research, discovery, selection, composition and integration. The pervasive systems correspond to a complete communication framework which allows the communicating objects to recognize and locate automatically. The pervasive system tasks are permitted by the semantic web services. The main interest of our research is to propose an adaptation framework of the application to the pervasive system based on semantic web services. In this paper, we present a part of our research work which represents the description of an OWL-S ontology extension to describe the pervasive system. This extension symbolizes the first level of data description in our pervasive system adaptation. © 2013 IADIS.

Statistical parametric approach for speech synthesis becomes more popular over the concatenative approach due to the low size of the system and the high-quality speech. Moreover, few researches have been done in the field of speech synthesis for Arabic language with a poor quality of speech. In this paper, we propose a statistical parametric synthesis system for Arabic based on Artificial Neural Networks (ANN). Mel frequency Cepstral coefficients (MFCC), F0, energy and duration are the main components of our system. Speech waveform is generated from the predicted parameters F0, energy and MFCC. Different methods are proposed for this development process. In addition, we propose a method to solve the problem of discontinuities between neighboring segment boundaries in order to improve the speech quality. Experimental results of cepstral and prosodic parameters are given in this paper as well as the subjective evaluation.

This paper presents a new method for 3D face pose tracking in arbitrary illumination change conditions using color image and depth data acquired by RGB-D cameras (e.g., Microsoft Kinect, Asus Xtion Pro Live, etc.). The method is based on an optimization process of an objective function combining photometric and geometric energy. The geometric energy is computed from depth data while the photometric energy is computed at each frame by comparing the current face texture to its corresponding in the reference face texture defined in the first frame. To handle the effect of changing lighting condition, we use a facial illumination model in order to solve which lighting variations has to be applied to the current face texture making it as close as possible to the reference texture. We demonstrate the accuracy and the robustness of our method in normal lighting conditions by performing a set of experiments on the Biwi Kinect head pose database. Moreover, the robustness to illumination changes is evaluated using a set of sequences for different persons recorded in severe lighting condition changes. These experiments show that our method is robust and precise under both normal and severe lighting conditions.

The Drowsiness is the risk to fall asleep for one moment with the closed eyes, it is an intermediate state between the awake and the sleep. This state is involuntary and it is accompanied by a fall of vigilance. Consequently, the development of a system for the automatic control of driver tiredness, to prevent the driver in advance of the accidents, received an interest growing of research mediums. In this work, we propose an approache of drowsiness detection which makes it possible to determine the 3D head orientation to capture the lack of concentration states. This approach is based on the estimate of the head rotation angles in the three directions Y aw, Pitch and Roll by exploiting only three interest points of the face. The approache suggested are evaluated by the MiraclHB database. The evaluation show many promising results and show the effectiveness of the approache suggested.

To reduce pre-bond and post-bond test cost for 3D IP (Three Dimensional Intellectual Property) cores, this paper proposed a test wrapper optimization technique using BFD(Best Fit Decreasing) and GA (Genetic Algorithm) algorithm under the constraints of TSVs(Through Silicon Vias) number, the proposed technique firstly used BFD to balance the length of pre-bond wrapper chains to reduce pre-bond test time. Then, on the basis of optimization results of pre-bond wrapper chains, the GA was used to stitch pre-bond wrapper chains to form balanced post-bond wrapper chains under the constrained TSVs number to reduce hardware overhead and post-bond test time. Experimental results demonstrated the presented methodology can effectively reduce hardware overhead at the cost of little increased test time. © 2014 IEEE.

Gliomas are the most common primary brain malignancies, with different degrees of aggressiveness, variable prognosis and various heterogeneous histologic sub-regions, i.e., peritumoral edematous/invaded tissue, necrotic core, active and non-enhancing core. This intrinsic heterogeneity is also portrayed in their radio-phenotype, as their sub-regions are depicted by varying intensity profiles disseminated across multi-parametric magnetic resonance imaging (mpMRI) scans, reflecting varying biological properties. Their heterogeneous shape, extent, and location are some of the factors that make these tumors difficult to resect, and in some cases inoperable. The amount of resected tumor is a factor also considered in longitudinal scans, when evaluating the apparent tumor for potential diagnosis of progression. Furthermore, there is mounting evidence that accurate segmentation of the various tumor sub-regions can offer the basis for quantitative image analysis towards prediction of patient overall survival. This study assesses the state-of-the-art machine learning (ML) methods used for brain tumor image analysis in mpMRI scans, during the last seven instances of the International Brain Tumor Segmentation (BraTS) challenge, i.e., 2012-2018. Specifically, we focus on i) evaluating segmentations of the various glioma sub-regions in pre-operative mpMRI scans, ii) assessing potential tumor progression by virtue of longitudinal growth of tumor sub-regions, beyond use of the RECIST/RANO criteria, and iii) predicting the overall survival from pre-operative mpMRI scans of patients that underwent gross total resection. Finally, we investigate the challenge of identifying the best ML algorithms for each of these tasks, considering that apart from being diverse on each instance of the challenge, the multi-institutional mpMRI BraTS dataset has also been a continuously evolving/growing dataset.

A two-leveled semantic web service description of the pervasive information system

To begin with, the semantic web service adaptation is based on the addition of contextual information to this web service description. So the technique of adapting the web service allows the user to establish reusable, interoperable, flexible and context-aware applications. The basic feature of the pervasive applications is the context-awareness. What is more, the pervasive systems are based on the NNN paradigm (aNywhere, aNytime, with aNything). Therefore, these systems must be used in different contexts depending on the user environment, his profile and the used terminal. Indeed, this type of system is dynamically adapted. Furthermore, we seek to offer a dynamic description of the web services. This objective, however, can be achieved by adding contextual information structures to the web service description. In the literature, more research works strive to combine the contextual description with the web service description by using the OWL-S structure. In fact, the main objective of this paper is to propose structures with two levels for the contextual description of the pervasive system. The first level is used to select the adapted web service to respond to the users needs, while the second level is aimed to offer the user the adapted description to respond to these needs. © 2013 Springer-Verlag.
