  • Laughter is one of the best emotional and physical therapies for anyone under stress. Laughing releases endorphins into the brain. Endorphins are like the nerve-numbing drug morphine and serve to reduce harmful chemicals in the body that are released by stress. As you know first-hand, one of the best ways to increase comfort in negative situations is to break the ice with laughter. When everyone is thinking the worst or feeling anxious about a situation, laughter can dissipate the tension just enough to give everyone a more manageable perspective on an issue. ...

  • We consider the question “How much strong generative power can be squeezed out of a formal system without increasing its weak generative power?” and propose some theoretical and practical constraints on this problem. We then introduce a formalism which, under these constraints, maximally squeezes strong generative power out of context-free grammar. Finally, we generalize this result to formalisms beyond CFG.

  • Electrical consumption, especially direct or variable frequency currents, has strongly increased over 50 years in industry. This situation explains the growth of power electronics. At the beginning, when rectifiers replaced DC machines, only diodes and thyristors were used. Then power transistors appeared and enabled the extension of smaller power applications for domestic use. New research topics were developed around converters and power devices.

  • Abstract: Industry standard for the control of switch mode power supply (SMPS) systems has been analog control. Now with the advent of high speed, lower cost digital signal processing (DSP) ICs, digital control there has been an increased interest in digital control of SMPS. The Power Electronics & Power Quality Laboratory of Texas A&M University is currently exploring several implementation aspects of digital control of power factor correction (PFC) stage of SMPS. Two low cost digital controllers: TMS320LF2407 and ST52x420 are evaluated for implementing PFC function.
