This system is the result of our previous work on the subject of school timetabling. It was designed to respond mainly to Portuguese schools from various educational levels. It consists of three main blocks; a graphical user interface; an automatic scheduler and a relational database. This system is now in use by more than 100 schools in Portugal with significant success (http://www.fmaismais.p...

In this paper, two types of dual permanent magnet (PM) machines, i.e., stator slot dual-PM (SSDPM) machine and split-tooth (STDPM) machine, are investigated compared. Both machines have consequent pole structure with Halbach array PMs. Their difference lies in the position PM. The SSDPM has PMs slots, while STDPM between split teeth. Torque characteristics, average torques torque ripples, diffe...

The arrays of compound-slots (inclined and displaced from waveguide centre) are not so common in the literature and the existing systematic method of design does not take into account the presence of surrounding elements. For this kind of slots, the reasons why the Elliott’s procedure cannot be applied are physically explained. A new method based on circuit theory and scattering matrices connec...

EM1 from slots and apertures resulting from coupling of interior sources through enclosure cavity modes in a Sun S-1000 workstation was investigated. The excitation of a specially designed rectangular enclosure with a slot was also studied experimentally and with finite-difference time-domain (FDTD) simulations. The radiated power results for both the S-1000 and simple rectangular enclosure ind...
