This paper investigates the potential hazards on human health caused by the radiation of wireless communications, and attempts to consolidate the outcomes of earlier studies in this respect. A review of causes and effects is carried out, and different views are discussed owing to the disagreement amongst researchers on the existence of hazards. Independent study and sample measurements have been attempted in this research, and have been compared with international radiation safety standards. The conclusion drawn by the authors indicates the existence of many health hazards that should be properly managed. It has not been possible to quantify the effects due to the multiplicity of sources, the varying sensitivities of people to radiation, and the long time it takes for the effects to appear. As most of the published research has been nonempirical, follow-up research is recommended to reveal more details. Read More Read Less

Abstract Classical approaches of Information Retrieval treat documents and queriesas «bags of words» with no syntax and no semantic.This representation is based on the co-occurrence of words in a textand does not take into account the semantic relationsth at exist between them. With the advent of ontologies,at the end of the 1990s, new approaches of Information Retrieval have appeared. These approaches... Classical approaches of Information Retrieval treat documents and queriesas «bags of words» with no syntax and no semantic.This representation is based on the co-occurrence of words in a textand does not take into account the semantic relationsth at exist between them. With the advent of ontologies,at the end of the 1990s, new approaches of Information Retrieval have appeared. These approaches attempt to capture the semantics of documents and queries by representing them with ontology concepts. A classical ontology doesnot avoid the vagueness and uncertainty that characterize human reasoning, in modeling the real world.Using the theory of possibility seems to be a solution. In this paper, we propose an indexing model based on possibilistic ontology. Therefore, we present a method for converting a conventional ontology into a possibilistic one and then we defineasemantic similarity measuresuitable for possibilistic ontology. The weights of index terms are based on the use of this measure. Read More Read Less

In the developed country, it is necessary that the enterprise should arrange the occupational physical examination yearly, there are millions cases, results in heavy loading to the hospital. Because of the limited scale, the hospital usually needs outsourcing physical examination institutes. But the introduction of the outsourcing institute results in problems of examination information sharing. Although the information systems for hospital have been developed for decades, and now there are various successful systems. But the information system for outsourcing institute integration is not yet developed. This study is to develop the information architecture for outsourcing institute integration, which is basing on the relational medical information standards, includes DICOM, HL7 CDA, and IHE XDS. The proposed architecture would provide the information sharing in heterogeneous systems for different hospitals. Read More Read Less

Abstract This paper proposes the development of a computational model which will be integrated into Virtual Learning Environment (Virtual-TANEB) that uses the Item Response Theory, statistical Models (Logistic Model of a parameter for dichotomous items with a population and Logistic Model parameters for three dichotomous items with a population) , to evaluate the proficiency of students in any area of knowledge.... This paper proposes the development of a computational model which will be integrated into Virtual Learning Environment (Virtual-TANEB) that uses the Item Response Theory, statistical Models (Logistic Model of a parameter for dichotomous items with a population and Logistic Model parameters for three dichotomous items with a population) , to evaluate the proficiency of students in any area of knowledge. This computer application is adapted to the student’s cognitive level through Artificial Intelligence (software agents: Adaptability, Pro-activity, Sociability, Autonomy and Reactivity). Initially, this software includes only the mathematics discipline content of 4th grade of elementary school, specially geometry providing the financial burden reduction and less time to deliver the student evaluation result.

Abstract This paper will present a technique for array diagnosis using a small numberof measured data acquired by a near-field system by making useof the concepts of compressed sensing technique in image processing.Here,the high cost of large array diagnosis in near-field facilitiesis mainly caused by the time required for the data acquisition.So there is a need to decrease the measurement time... This paper will present a technique for array diagnosis using a small numberof measured data acquired by a near-field system by making useof the concepts of compressed sensing technique in image processing.Here,the high cost of large array diagnosis in near-field facilitiesis mainly caused by the time required for the data acquisition.So there is a need to decrease the measurement time and at the same time the reconstruction of an array must be satisfactory.The proposed technique uses less number of measurement points compared to other proposed techniques like back-propagation method and standard matrix inversion method.
