We study a strategic model in which a defender must allocate defensive resources to a collection of locations, and an attacker must choose a location to attack. The defender does not know the attacker's preferences, while the attacker observes the defender's resource allocation. The defender's problem gives rise to negative externalities, in the sense that increasing the resources allocated to ...

reactive power management plays an essential role in the secure operation of the power system as an ancillary service. although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. on the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the secur...

The efficient and economic allocation of resources is one main goal in the field of production planning and control. Nowadays, a new variable gains in importance throughout the planning process: Energy. Energy-efficiency has already been widely discussed in literature, but with a strong focus on reducing the overall amount of energy used in production. This paper provides a brief systematic app...

A channel allocation algorithm includes a channel acquisition and a channel selection scheme. Most of the previous work concentrates on the channel selection algorithm since early channel acquisition algorithms are centralized and rely on a MSS to accomplish channel acquisition. The centralized schemes are neither scalable nor reliable. Recently, distributed dynamic channel allocation algorithm...

Current processor allocation techniques for highly parallel systems are based on centralized front-end based algorithms. As a result, the applied strategies are restricted to static allocation, low parallelism and weak fault tolerance. To lift these restrictions we are investigating a distributed approach to the processor allocation problem in large distributed memory machines. A contiguous and...

The efficient use of the bandwidth allocated for a cellular wireless network is crucial for the satisfactory performance of the system. In order to increase the channel utilization, the channels are allocated to different cells in a dynamic way. The dynamic channel schemes can be categorized in to centralized and distributed. However, the centralized schemes are neither reliable nor scalable. T...

Grid computing has recently become an important paradigm for managing computationally demanding applications (composed of a collection of services). Providing dynamic discovery of services, and the determination of a service with the “best value” remains a complex problem in Grid computing. Such a decision is a multi-attribute n : m allocation problem, and often made using a centralized compone...

In this work, we examine the downstream impediments of centralized Ethernet passive optical networks supporting LAN emulation [inter-Optical Network Units communication(ONU)]. The available downstream bandwidth in the centralized scheme is reduced due to LAN emulation and upstream bandwidth allocation functions. The reduction in available downstream bandwidth results in degraded downstream perf...

Cloud computing is gaining strength in the IT marketplace because of its on-demand resource provisioning, high availability and elasticity. To offer these advantages, many largely centralized computing infrastructures have emerged, which results in many concerns such as resource over-provisioning, huge energy consumption, privacy protection, data security, etc. In this proposal, we envision a d...

BACKGROUND Decreasing hospital length of stay, and so freeing up hospital beds, represents an important cost saving which is often used in economic evaluations. The savings need to be accurately quantified in order to make optimal health care resource allocation decisions. Traditionally the accounting cost of a bed is used. We argue instead that the economic cost of a bed day is the better valu...
