This paper proposes a generalized space vector pulse width modulation (SVPWM) technique for hybrid multilevel inverters for minimizing total harmonic distortion (THD). The proposed method easily determines the actual location of the instantaneous reference space vector and the corresponding switching sequence of a multilevel inverter. The proposed algorithm offers a novel method for minimizing ...

We propose a novel paging strategy based on the theory of optimal search with discrete efforts. When compared to conventional paging methods, the proposed scheme increases the mobile station discovery rate while decreasing the average number of times that a mobile station has to be paged in a location area. The proposal is fully compatible with existing cellular structures, and requires minimal...

The attentional blink (AB) is a well-established paradigm in which identification of a target T2 is reduced shortly after presentation of an earlier target T1. An important question concerns the importance of backward masking during the AB. While task switching has been found to be a strong modulator mediating the AB without any masking of T2, the present study investigated whether spatial swit...

Annotation: Two pass routing scheme is described for communication in a multiprocessor system employing a unique-path multistage interconnection network in the presence of faults in the network. It is capable of tolerating all single faults and many multiple faults in all except the first and last stages of the network. The routing scheme is useful for tolerating both permanent as well as inter...

Ferromagnetic metal rings of nanometre range widths and thicknesses exhibit fundamentally new spin states, switching behaviour and spin dynamics, which can be precisely controlled via geometry, material composition and applied f eld. Following the discovery of the ‘onion state’, which mediates the switching to and between vortex states, a range of fascinating phenomena has been found in these s...

BACKGROUND There exists a relation between the presence and location of the micro-gap and the loss of peri implant bone. Several authors have shown that the treatments based on the use of platform switching result in less peri-implant bone loss and an increased tissue stability. The purpose of this study was to analyse the effect of the platform switching on the distribution of stresses on the ...

Two experiments examined the interaction between aging, attention switching, encoding process, and recognition memory using different versions of a cued attention switching paradigm. In Experiment 1, 30 younger and 35 older adults encoded words based on font color, meaning, or by explicit learning with a color response during performance of a choice-reaction time (RT) task. Attention switches w...

BACKGROUND Previous studies have shown that patients with schizophrenia are impaired on executive tasks, where positive and negative feedbacks are used to update task rules or switch attention. However, research to date using saccadic tasks has not revealed clear deficits in task switching in these patients. The present study used an oculomotor 'rule switching' task to investigate the use of ne...
