In this paper we study a single machine scheduling problem with the objective of minimizing sum completion times. Each given jobs is either short or long. However processing times are initially hidden to algorithm, but can be tested. This done by executing time oracle, which reveals job. test occupies unit in schedule, therefore algorithm must decide for it will call oracle. The value resulting...

as the e-commerce sites are being more secure and reliable in recent years and the number of transactions is rising rapidly, parallelism can help us to reduce response time and increase throughput for e-commerce transactions. this paper will investigate parallelism in on-line transaction processing. it aims to specify those aspects of e-commerce transactions that would profit from parallel proc...

a model capable of predicting the minimum content of aflatoxin m1 (afm1) in iranian while brine cheese has been developed using a chemometric approach to determine the optimum processing conditions. renneting temperature, cut size, stirring time, press time, curd size and saturated brine ph were all regarded as process variables. three-dimensional response surface and contour plots were drawn. ...

Space-time adaptive processing (STAP) is a well-known and effective method to detect targets, obscured by interference, from airborne radars that works coherently combining signals phased antenna array (spatial domain) with multiple radar pulses (temporal domain). As widely demonstrated, optimum STAP, in the sense of maximizing output signal interference plus noise ratio (SINR), coherent, linea...
