A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...

For large high-speed globally synchronous ASICs, designing the clock distribution net becomes a troublesome task. Besides problems caused by clock skew, the clock net also is a major source of power consumption. Partitioning the design into locally clocked blocks reduces clock skew problems and if handled correctly it also reduces power consumption. However, to achieve these positive effects, t...

Objectives: Children’s auditory event-related potentials (ERPs) are dominated by the P1 and N2 peaks, while the N1 wave emerges between 3 and 4 years of age. The neural substrates and the behavioral correlates of the protracted N1 maturation, as well as of the 10-year long predominance of the N2 are unclear. The present study utilized high-resolution electroencephalography to study the maturati...

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

We explore asynchronous programming with algebraic effects. complement their conventional synchronous treatment by showing how to naturally also accommodate asynchrony within them, namely, decoupling the execution of operation calls into signalling that an operation’s implementation needs be executed, and interrupting a running computation result, which can react installing interrupt handlers. ...

An identity-based encryption (IBE) scheme can greatly reduce the complexity of sending encrypted messages over the Internet. However, an IBE scheme necessarily requires a private-key generator (PKG), which can create private keys for clients, and so can passively eavesdrop on all encrypted communications. Although a distributed PKG has been suggested as a way to mitigate this problem for Boneh ...

The Consensus problem is a fundamental problem one has to solve to implement reliable services or applications on top of asynchronous distributed systems prone to failures. Unfortunately , this problem cannot be solved in those systems as soon as one process can crash (Fischer-Lynch-Paterson's impossibility result). Two approaches have been investigated to circumvent this impossibility result. ...

A distributed system may be modeled by objects that run concurrently, each with its own processor, and communicate by remote method calls. However objects may have to wait for response to external calls; which can lead to inefficient use of processor capacity or even to deadlock. This paper addresses this limitation by means of asynchronous method calls and conditional processor release points....
