The paper presents a study on business micro-location behaviour as well as corresponding factors of influence, conducted in two metropolitan areas, Bucharest-Ilfov (Romania) and Greater Porto (Portugal). By business micro-location we refer to a specific site such as a building or facility, accommodating a business within a small, compact geographical area (e.g. metropolitan area). At this geographical...
Permanent magnet synchronous motors (PMSM) are used in a great variety of applications such as: electric toys, electric tools, medical/chemical industries, centrifuges at high speed, vehicle applications (motor starters), robot applications etc. All these have in common small size, high energy density, increased torque for a large speed range, high dynamics when high inertia is present. In consequence,...
Schizophrenia is a human specific disease, unknown in other primates. Low adiposity during childhood was associated with a greater risk of developing schizophrenia, but this disease has a higher incidence in the obese children and adults, too.We developed a new hypothesis on the human evolution. According to it, changes in the activity of the IGF1 (insulin-like growth factor1)/insulin pathway (altered...
The paper presents numerical simulation results and experimental data used for modeling a hybrid step motor (HSM). Two different HSM models have been developed starting from available technical data of a HSM (2-phase, bipolar, frame size 56.4 mm). One of the models is adequate for analyzing the HSM response to different control strategies, while the second one can be used for performing an electromagnetic...
The paper presents the design, the calculus and a numerical simulation of the magnetic field, the electromotive force and the electromagnetic forces for a direct driven permanent magnet linear generator buoy, used to generate electric energy based on the sea wavepsilas energy. The magnetic field is computed using finite element method applied on a 3D model of the generator.
Parallel and distributed computing infrastructure is increasingly being embraced in the context of manufacturing applications, including real-time scheduling. The paper present the design and implementation of one such framework than can work on the Internet, with applications in automation (manufacturing). The architecture of distributed and parallel computing framework (DPAC) has the goal of harnessing...
