Partial rigid-body dynamics in NPT, NPAT and NPT ensembles for proteins and membranes

A partial rigid-body method of molecular dynamics simulations for proteins and membranes is presented. In this method, the symplectic integrator for rigid bodies is combined with the equations of motion for the NPT ensemble. The standard NPT ensemble is extended to the membrane-specific ensembles, the NPAT (constant normal pressure and lateral surface area of membranes and constant temperature)...

On the Intellectual Terrain around Npt

In this paper we view Pd,NP as the problem which symbolizes the attempt to understand what is and is not feasibly computable. The paper shortly reviews the history of the developments from Göde1's 1956 letter asking for the computational complexity of finding proofs of theorems, through computational complexity, the exploration of complete problems for NP and PSPACE, through the results of stru...

New Compact Igbt Modules

A new family of compact IGBT modules has been developed to bridge the gap between fully integrated IPM devices and basic IGBT modules. The idea of this new family was to give the designer the dynamic control offered by conventional IGBT modules while maintaining the reliability provided by integrated current and temperature sensing. The result is a new family of dual (half-bridge) modules with ...

Integrated Smart Power IGBT Drivers

The concept of IGBT modelling and the evaluation of the PSPICE IGBT model

The ability to calculate power losses in the Insulated Gate Bipolar Transistors (IGBTs) embedded in a series resonant converter is of great interest at ALSTOM Power, Växjö. Correctly estimated power losses are valuable in various situations, e.g. when evaluating new types of IGBTs or different control strategies. Therefore, it is desirable to investigate and evaluate the existing computer based...
