The Technical Customer Service (TCS) represents an essential part of the so-called Product-Service System (PSS) and requires intelligent support in its product-related operations with technical goods and knowledge intensive activities. This makes information to a fundamental contribution for a qualitative service delivery. Therefor, IT-based mobile service support systems are seen as a necessit...

Blood and body fluid Exposure is a major occupational safety problems for health care workers. Therefor We conducted a descriptive and retrospective study to identify the characteristics of blood exposure accidents in health care settings which lasted five years (2005-2009) at the two university hospitals of Sfax. We have 593 blood exposure accidents in health care settings 152 (25.6%) health p...

Modern control design of large industrial plants relies strongly on modelling, while experimentation on the real system is extremely limited. The usable model should be intuitive and easily reusable to model potential plant adaptations or similar plants. In this paper some aspects of the modelling a recuperator plant consisting of four heat exchangers are presented. With the object-oriented mod...

In the last two decades many authors have developed techniques to measure the efficiency of Decision Making Units in a way consistent with the underlying economic theory of optimization behavior. The model frequently used is Data Envelopment Analysis (DEA) which initially developed by Charnes, Cooper and Rhodes (1978). Using such as efficiency method over two consecutive periods, one can natura...

Design space exploration is commonly performed in embedded system, where the architecture is a complicated piece of engineering. With the current trend of many-core systems, design space exploration in general-purpose computers can no longer be avoided. Microgrid is a complicated architecture, and therefor we need to perform design space exploration. Generally, simulators are used for the desig...

Improvements and portability of technologies and smart devices have enabled a rapid growth in the amount of user generated media such as photographs and videos. Whilst various media generation and management systems exist it still remains a challenge to discover the right information, for the right purpose. This paper proposes an approach to reverse geocoding by crossreferencing multiple geospa...

While users increasingly use such large multimedia data, more people use the cloud computing technology. It is necessary to manage large data in an efficient way, and to consider transmission efficiency for multimedia data of different quality. To this end, an important thing is to ensure efficient distribution of important resources (CPU, network and storage) which constitute cloud computing, ...

This literature review was conducted to summarize the main points of maternal thyroid function tests, with particular attention in the first trimester of pregnancy which accompanied with significant biochemical and metabolic alteration. The evaluation of thyroid function of either hyperthyroidism and hypothyroidism should be assessed by determination of serum Thyroid Stimulating Hormone (TSH), ...

Emotional competence plays a crucial role in human communication and hence should also be considered for improving cooperation between humans and robots. In this paper we present an architecture and its realization in the robot head MEXI, which is able to recognize emotions of its human counterpart and to react adequately in an emotional way by representing its own emotions in its facial expres...

In this paper, we propose a low bit rate waveform interpolation speech coder where the novelty lies with an e ective decomposition method of pitch cycle waveform(PCW). PCWs exhibit very di erent perceptual characteristics in di erent frequency bands. For frequency components below 1kHz, they are quantized using Variable Dimensional Vector Quantization(VDVQ) scheme. Hereby retaining the ne harmo...
