In this paper we study the scheduling of parallel and real-time recurrent tasks. Firstly, we propose a new parallel task model which allows recurrent tasks to be composed of several threads, each thread requires a single processor for execution and can be scheduled simultaneously. Secondly, we define several kinds of real-time schedulers that can be applied to our parallel task model. We distin...

This paper analyses the resource allocation problem in parallel jobs scheduling, with emphasis given to gang service algorithms. Gang service has been widely used as a practical solution to the dynamic parallel job scheduling problem. To provide a sound analysis of gang service performance, a novel methodology based on the traditional concept of competitive ratio is introduced. Dubbed dynamic c...

BACKGROUND On December 16, 2012 a 23 year old female was gang-raped on a bus in Delhi. We systematically reviewed professional online media sources used to inform the timing, breadth of coverage, opinions and consistency in the depiction of events surrounding the gang-rape. METHODS We searched two news databases (LexisNexis Academic and Factivia) and individual newspapers for English-language...

Nondestructive evaluation of the prevailing compressive residual stress in the shallow subsurface layer of surface-treated metals is greatly complicated by the accompanying surface roughness and cold work. A high-precision laser-ultrasonic technique has been developed to study the feasibility of SAW dispersion spectroscopy for residual stress assessment on surface-treated metals in a wide frequ...
