The paper presents a mathematical model of a turbulence pickling line, designer! to remów the oxide layer, known as scale, from a plain steel strip by means of a pickling medium, e.g. hydrochloric or sulphuric acid. The constituent parts of the installation and the differential equations describing the processes that take place inside of them, as well as effects encountered during the pickling process...
Low-voltage MOSFETs are widely used in the synchronous rectifying stages of power supplies. To allow a high efficiency in light-load conditions, the power MOSFET not only needs to meet general requirements like low on-resistance, low gate charge and good avalanche capability, but must also have a low output capacitance and low reverse-recovery charge. The paper shows how those requirements were met...
The High Level Trigger (HLT) and Data Acquisition System select about 2 kHz of events out of the 40 MHz of beam crossings. The selected events are consolidated into files on an onsite storage and then sent to permanent storage for subsequent analysis on the Grid. For local and full-chain tests a method to exercise the data-flow through the HLT when there are no actual data needed. In order to test...
The purpose of this study was to examine ways to improve and advance the instruction of electricity and physics in institutes of higher education by implementing teaching methods that combine computerized simulations and animations together with conventional teaching methods. Qualitative and quantitative methods of research were combined in this study. An innovative observation model was used to conduct...
