Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...

Wireless communication networks have recently attracted significant research attention. As a critical issue for improving network performance, efficient and intelligent resource allocation strategies have been intensively studied. This thesis consists of two studies on resource allocation strategy, specifically, joint bandwidth and power allocation strategy, for wireless communication networks ...

This paper proposes an optimal allocation problem with ramified transport technologies in a spatial economy. Ramified transportation is used to model network-like branching structures attributed to the economies of scale in group transportation. A social planner aims at finding an optimal allocation plan and an associated optimal allocation path to minimize the overall cost of transporting comm...

This paper proposes a new method based on the ideal input vector to estimate inputs of a given decision making unit (DMU) when some or all of its outputs are increased to maintain its current efficiency level. In other words, this paper studied the following question: How much would be the increase in the inputs of the DMU if the decision maker increases certain outputs to a particular unit in ...

A principal (dean) has an object (job slot) to allocate to one of I agents (departments). Each agent has a strictly positive value for receiving the object. Each agent also has private information which determines the value to the principal of giving the object to him. There are no monetary transfers but the principal can check the value associated with any individual at a cost which may vary a...

This paper gives very general algorithms for the design of optimal experiments involving two Bernoulli populations in which sampling is carried out in stages. It is assumed that the outcomes of the previous stage are available before the allocations for the next stage are decided. At each stage, one must decide how many observations to take and how many to sample from each of the alternative po...

This paper gives algorithms for the design of optimal experiments involving Bernoulli populations in which allocation is done in stages. It is assumed that the outcomes of the previous stage are available before the allocations for the next stage are decided and that the total sample size for the experiment is xed. At each stage, one must decide how many observations to take and how many to sam...

Often an organization or government must allocate goods without collecting payment in return. This may pose a di¢ cult problem either when agents receiving those goods have private information in regards to their values or needs or when discriminating among agents using known di¤erences is not a viable option. In this paper, we …nd an optimal mechanism to allocate goods when the designer is ben...
