We consider stochastic optimization problems in which the input probability distribution is not fully known, and can only be observed through data. Common procedures handle such problems by optimizing an empirical counterpart, namely via using an empirical distribution of the input. The optimal solutions obtained through such procedures are hence subject to uncertainty of the data. In this pape...

Multicast and broadcast service (MBS) is one of the important services for next-generation wireless systems. In WiMAX, the radio resource unit (i.e., time, frequency, code, etc.) for MBS is centralized allocated by an anchor access service network gateway (Anchor ASN-GW). In MBS, a BS can dynamically join or leave an MBS Zone due to the moving of MSs. The Anchor ASNGW must allocate nonoverlappi...

the sunn pest, eurygaster integriceps put. is an important pest of wheat in firozabad region of ardabil province, iran. in this study the spatial distribution of overwintered adult was investigated in rainfed wheat fields. then, fixed precision sequential sampling plan was developed and validated for estimating overwintered adult density. iwao's patchiness regression gave a better fit to d...
