A multi-scale optimisation problem, formulated on both a macro and a micro scale, is considered. On the macro scale \(\Omega \) is discretised using \(N_e\) equal-sized quadrilateral elements \(e\in \mathcal {T}^{c}\). Let \(\Omega _e\subseteq \Omega \) denote the domain spa...
high efficiency, high input voltage switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 96% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting ...
Fortunately, this load-independent point occurs in the inductive region of the voltage gain characteristic, where the resonant tank current lags the input voltage square waveform (which is a necessary condition for ZVS behavior). The regulation of the converter output voltage is achieved by ...

Instead, supposing a transmission time tTX of 1 s and a duty cycle d of 50%, according to the graph of Figure 25 the θJA would be 15 °C/W only. In this case a power dissipation of 2.7 W (corresponding to a 1 Ω load) is allowed over the entire ambient temperature...
While there are several advantages of preferring high voltage for transmission such as reduced line losses, increased transmission efficiency and better voltage regulation, there are also some parameters which limit higher voltage level. These are increase in insulation required between the conductors and...
The devices comply with the applicable standards and regulations in accordance with EN 61010 "Protection Measures for Electrical Equipment for Measurement, Control, Regulation and Laboratory Procedures". They can, however, be a source of danger if used incorrectly or for anything other than the ...
Cameras with extreme speeds are enabling technologies in both fundamental and applied sciences. However, existing ultrafast cameras are incapable of coping with extended three-dimensional scenes and fall short for non-line-of-sight imaging, which require
The left graph illustrates how stride mean and range of motion (ROM) were calculated, shown on an example of a lateral bending stride curve (blue line indicates the mean, shaded area the standard deviation). The right graph illustrates the variablesa‘Head swivel’ andb‘Body tracking’, with...
