the distally based sural fasciocutaneous flap has become a main part of the reconstruction of the lower leg, heel and foot. however, perfusion problems and venous congestion have been reported. over the past decade, several flap modifications have been reported to improve flap viability and to solve a myriad of reconstructive needs. the purpose of this paper is to describe our experience in har...

In many application areas such as airlines and hotels a large number of bookings are typically cancelled. Explicitly taking into account cancellations creates an opportunity for increasing revenue. Motivated by this we propose a revenue management model based on Talluri and van Ryzin [27] that takes cancellations into account in addition to customer choice behaviour. Moreover, we consider overb...

Cloud computing datacenters provide millions of virtual machines in actual cloud markets. In this context, Virtual Machine Placement (VMP) is one of the most challenging problems in cloud infrastructure management, considering the large number of possible optimization criteria and different formulations that could be studied. Considering the on-demand model of cloud computing, the VMP problem s...

closure of fascia after transverse rectus abdominis musculocutaneous (tram) flap has usually been performed with direct closure or synthetic material. the dermal autograft was removed from zone iv of flap was an alternative to reinforce fascial closure. the dermal autograft was used in 34 patients after tram harvest for breast, head and neck reconstruction and prolene mesh was used in 42 other ...

To formulate a single-leg seat inventory control problem in an airline ticket sales system, the concept and techniques of revenue management are applied in this research. In this model, it is assumed the cabin capacity is stochastic and hence its exact size cannot be forecasted in advance, at the time of planning. There are two groups of early-reserving and late-purchasing customers demanding t...
