Present research deals with comparative studies, analysis and experiments between three types of supercapacitors packs, in order to obtain the optimal structures for applications in which they are integrated. Two of proposed packs are high voltage used in electrical vehicle sphere and one is realized for low power circuits from electronic application. A summary review regarding the supercapacitors...
There are a lot of studies that show the effect of coupled lines, but most implementation in MatLab are based on using an n-section lump circuit approximation model, which has a limited bandwidth. Also on every PCB, on a trace it appears a capacitive discontinuity, that influences the coupling of the transmission lines. We propose another approach to describe the coupled lines, and which will be capable...
Level measurement is the most important process which has to be followed in the dam's sensorial management department. Thus, the evaluation of the water seepage through the dam walls is becoming a first order parameter to be followed for the dam security monitoring. The level is measured before the weir boxes - where the water is collected via the existing drillings, into the special built gutters...
Technological improvements have led to the development of low resistivity materials with higher surface which are capable of storing more energy in the form of electrical charge. These developments as well as a better theoretical understanding of the process of charge transfer, a process that appears in double layer type materials, led to the development of capacitors with high capacitance, known...
