Thermoelectric generators (TEGs) are used for the direct conversion of heat energy into electricity. Given that there is an extreme concentration of heat present on house roofs, the application of TEGs on these locations is feasible. This study involves the modeling of thermoelectric generators on house roofs through the use of simulations and an actual prototype. Simulations were done using the matrix...
A future soldier carries a large gear weight in the battle because of increasing in the number of electronic devices such as communication equipment, sensors, or battlefield situational displays. These devices are necessary to save his life and ensure the victory in the combat. So, the wearable energy harvesting technology is the optimal solution to provide the energy to the soldier's electronic devices...
Modeling and numerical simulation of the triple effect desalination plant coupled with thermo-vapor compressor is performed. The desalination system is an industrial application of desalination seawater used in the Tunisian Chemical Group (GCT), which located in Tunisia. The plant composed in three subsystems; effects, condenser, and compressor; which presented their mass and energy balances. The...
Quad copters are VTOL aerial robot systems and has complex dynamics in spite of its simple design. In the present work, a quadcopter of plus configuration is assembled and its flight characteristics are experimentally studied. To stabilize the system during its flight a KK multicopter platform is used. Flight stabilization is done and data of motor input voltage is acquired using a arducopter flight...
In order to enhance the study of the kinematics of any robot arm, parameter design is directed according to certain necessities for the robot, and its forward and inverse kinematics are discussed. The DH convention Method is used to form the kinematical equation of the resultant structure. In addition, the Robotics equations are modeled in MATLAB to create a 3D visual simulation of the robot arm to...
In system-level design, descriptive system models seem to be insufficient in order to perform a system verification which fulfils various stakeholders0 requirements. This fact is accentuated by the increasing complexity of system engineering projects and, as a consequence, the difficulties to deal with both their coordination and trace ability. Even if SysML (System Modeling Language) is considered...
This article presents an economic feasibility study for replacement of electric power generators Diesel fuel stations by photovoltaic generation. This proposal is based on the use of a renewable source of energy with a view to a healthier environment is auguring-results and discussions to a promising future, especially considering these energy sources do not increase emissions of greenhouse gases,...
There are many industrial applications where precise delivery of fluid required such as ratio blending, delivery system, etc. One of such application is petroleum product delivery system. As the price of these petroleum products is increasing day by day, it is important to deliver the exact demanded quantity of product to the customer. For such delivery systems the digital control valve is used. This...
The solid oxide fuel cell (SOFC) is a new energy power system. For the planar solid oxide fuel cells, the temperature distribution in a single cell is essential to the normal operation of a stack as well as the entire system. In order to estimate the temperature distribution in the cross-flow planar SOFC, this paper established a SOFC temperature field model in the matlab/simulink platform according...
Even if it is considered as an effective language for system modeling because of the descriptive aspect of its diagrams, SysML (System Modeling Language) is insufficient for verification of their behavior. This lack is accentuated by the increasing complexity of recent systems. In order to conduct behavior verifications, designers use simulation tools to realize experiments on the studied system....
The subject of the paper is focused on the analysis of a 30kW switched reluctance machine for propulsion of electrical vehicle propulsion (EV). The paper details the fundamental steps when developing such an electrical machine, and validates the structure using co-simulation procedures, coupling finite element analysis software (Cedrat Flux2D) with software used to implement the controller (Matlab/Simulink)...
Modeling complex mechatronic systems containing parts such as mechanics, electronics and software is a major challenge for the engineering of automation production systems. As a result, many modeling languages as well as tools (e.g. petri nets or MATLAB/Simulink) and verification approaches (e.g. testing, simulation or formal verification) that focus on special challenges to model the mechatronic...
In this paper, we share our experience in using an innovative approach of teaching Engineering Science established by the French Ministry of Education for the French national preparatory classes for grandes écoles. The engineering science curriculum has moved from theoretical-based teaching into an engineering workflow-based style that considers engineering skills as an integrated part of the learning...
A surface Electrogastrography (EGG) system uses electrodes placed on the abdomen of the patient to verify the gastric myoelectric activity. Physicians use EGG systems to aid the patients' diagnosis with gastric disorders. In this context, the results of the EGG examinations must be accurate to avoid errors on the patient's evaluation. The medical device and the software to control the device must...
The penetration of renewable energy technologies into energy markets is on the increase due to significant drops in their capital cost, increase in their efficiency and improvement in storage system and power electronic interface. Most universities around the globe offer, nowadays, renewable energy courses within the electrical and mechanical engineering curricula to support the increasing demand...
Maximal energy harvesting of photovoltaic panels is possible only if the load of photovoltaic cell is consuming current that corresponds to the maximal power point for condition combination on a certain moment. Correct and detailed mathematical modeling of photovoltaic panels is able to help to develop control techniques for maximum power point tracking converters. In order to overcome the disadvantages...
This paper present a detailed model of wind conversion chain based on a PMSM oriented to the simulation. Wind model is presented both variable and constant case with that blade and turbine. The latter consists of the conversion of wind energy into mechanical energy which is transmitted to the shaft of the PMSM, which was modeled then simuled with Matlab Simulink. Also the control of PMSM output voltage...
The work presented in this article is registered in the context of the preparation of a diagnostic platform for the industrial diagnosis of a photovoltaic plant.

Then we selected to model...
Understanding photovoltaic (PV) cell operation relies on accurate models being available that follow practical PV characteristics. Many models are proposed in the literature that vary in their complexity and range of application. This paper investigates the key issues involved in developing an accurate PV cell model that can demonstrate the effects of environmental factors. Operational constraints...
