Researching the evolution and maintenance of reproductive mode (oviparity, ovoviviparity and viviparity) is important for identifying the intrinsic and environmental pressures associated with maternal care. We studied the life history, reproductive mode and sex allocation of Bactrothrips brevitubus, a haplodiploid, facultatively ovoviviparous Japanese thrips. Individual females can produce a ma...

This paper proposes a new resource allocation model which is based on data envelopment analysis (DEA) and concerns systems with several homogeneous units operating under supervision of a central unit. The previous studies in DEA literature deal with reallocating/allocating organizational resource to improve performance or maximize the total amount of outputs produced by individual units. In tho...

This paper presents an experimental investigation of the Sounds of Silence (SoS) harmony search metaheuristic for the multi-mode resource-constrained project scheduling problem (MRCPSP) using a pre-optimized starting repertoire. The presented algorithm is based on the time oriented version of the SoS harmony search metaheuristic developed by Csébfalvi et al. [1] for the single-mode resource-con...

The Colorado River basin is facing a growing water shortage. Under fixed set of supply and demand conditions, we establish linear programming model based on time to solve the problem allocation. Take as objective function, get distribution coefficient α, β obtain from Hoover dam Glen Canyon dam. Finally it concluded that optimal function obtained when α 0.8 1.0. Dam 6947519530 m3 9309140232 m3.

The increasing complexity of today’s reactive embedded applications can rapidly result in reduced real-time capabilities of the underlying hard and software. As an example for this paper we’ll refer to the specific and growing demands on the severely resource constrained sensor nodes in sensor/actuator networks (SANet). While preemptive operating systems are one way to retain acceptable reactiv...
