Radio- and chemotherapy for malignant neoplasms, especially in head and neck region, is associated with a greater risk of fungal infections due to secondary alterations in the mucous membranes. The study had three aims: 1.to determine the signs and symptoms which occur among patients undergoing radiotherapy; 2. to determine the fungi prevalence in the mouth and throat of patients before, during...

We introduce and study the batched bin packing problem (BBPP), a bin packing problem in which items become available for packing incrementally, one batch at a time. A batched algorithm must pack a batch before the next batch becomes known. A batch may contain several items; the special case when each batch consists of merely one item is the well-studied on-line bin packing problem. We obtain lo...

In traditional batch-service queueing systems, the mean service time of batches are generally assumed to be constant. However, in numerous applications this assumption may not appropriate. telecommunication networks, transmission rates depend on number packets batch which can framed as batch-size-dependent queue. The objective paper is focus both queue and server content distribution an infinit...

This paper contains a design proposal for facilities for doing batch simulations in Design/CPN. These facilities can be used for running a group of simulations without user interaction. We discuss what kind of functionality is needed to run batch simulations. We also give proposals on how to implement this functionality in Design/CPN. To illustrate the use of the batch scripting facilities we p...

Run-to-run optimization methodologies exploit the repetitive nature of batch processes to find the optimal operating policy in the presence of uncertainty. For the class of batch optimization problems where the solution is determined by terminal constraints, the update of the decision variables towards their optimal values is realized using a constraint control scheme. The methodology is adapte...

We consider an online scheduling problem in a parallel batch processing system with jobs in a batch being allowed to restart. Online means that jobs arrive over time, and all jobs’ characteristics are unknown before their arrival times. A parallel batch processing machine can handle up to several jobs simultaneously. All jobs in a batch start and complete at the same time. The processing time o...
