One of the most common issues in inverters are open-circuit faults (OPF). In this scenario, a proper fault-tolerant technique must be used to improve motor performance. Although basic modulation techniques normally preferred, paper proposes discontinuous pulse-width algorithm (HD-PWM) operate five-phase under single OPF. particular, loss equalization between remaining switches after fault occur...

Background: The treatment of open tibial fractures is still an orthopaedic challenge and full of complications. In many cases the use of external fixator that has been known as a non-union machine is obligatory with a high incidence of pin track infection and other complications. The aim of this study was to compare the use of external fixation as a definite method for treatment of open tibial ...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

We investigate, in a certain decoupling limit, the effect of having a constant C– field on the M–theory five–brane using an open membrane probe. We define an open membrane metric for the five–brane that remains non–degenerate in the limit. The canonical quantisation of the open membrane boundary leads to a noncommutative loop space which is a functional analogue of the noncommutative geometry t...
