It is known that distillation in continuous variable resource theories impossible when restricted to Gaussian states and operations. To overcome this limitation, we enlarge the include convex mixtures of This extension operationally well-motivated since classical randomness easily accessible. We find becomes possible for theories-albeit a limited fashion. derive limitation by studying roof meas...

during the implementation, construction projects usually encounter situation that considerably affects the project scheduling and cost. this study aims at using an improved version of the harmony search algorithm (hsa) to schedule resource constrained construction projects. this model is formulated as a global optimization problem. it will determine the duration of each activity to minimize the...

In this paper, we consider scheduling of project networks under minimization of total weighted resource tardiness penalty costs. In this problem, we assume constrained resources are renewable and limited to very costly machines and tools which are also used in other projects and are not accessible in all periods of time of a project. In other words, there is a dictated ready date as well as a d...

Human resource management has increasingly become one of the most important challenging issues in the pharmaceutical industry in general and in developing countries in particular to increase the access of societies to needed medicines. In this study, an attempt was made to explore the challenges of human resource management practices surrounding pharmaceutical firms in Iran, as a developing cou...
