Overfishing can lead to the reduction or elimination of fish populations and the degradation or even destruction of their habitats. This can be prevented by introducing Marine Protected Areas (MPA’s), regions in the ocean or along coastlines where fishing is controlled. MPA’s can also lead to larger fish densities outside the protected area through spill-over, which in turn may increase the fis...

The fields of detection, resource allocation, and security have seen tremendous research activity in the past few decades. Different frameworks have been designed to tackle various problems using a host of techniques from statistics, engineering, and economics. The fields of centralized and decentralized detection, see [1] for a review, have been a major research focus in the communications, co...

A study on cache proxy placement for tree-based topology is presented in this paper. Web caching has been developed maturely to deal with burst increasing network traffic. Most existing works on web caching focus on contentbased issue. Some of the newly published papers discussed the placement of caches and presented algorithms to find out the optimal solution. However, they all assume constant...

Cloud computing provides a computing platform for the users to meet their demands in an efficient, cost-effective way. Virtualization technologies are used in the clouds to aid the efficient usage of hardware. Virtual machines (VMs) are utilized to satisfy the user needs and are placed on physical machines (PMs) of the cloud for effective usage of hardware resources and electricity in the cloud...

We consider the problem of finding all enclosing rectangles of minimum area that can contain a given set of rectangles without overlap. Our rectangle packer chooses the xcoordinates of all the rectangles before any of the y-coordinates. We then transform the problem into a perfect-packing problem with no empty space by adding additional rectangles. To determine the y-coordinates, we branch on t...

We consider the reconstruction of shared secrets in communication networks, which are modelled by graphs whose components are subject to possible failure. The reconstruction probability can be approximated using minimal cuts, if the failure probabilities of vertices and edges are close to zero. As the main contribution of this paper, node separators are used to design a heuristic for the near-o...

 Dental implants, as a result of their excellent success rates and advantages over fixed or removable methods, have become the optimal treatment for replacing missing teeth. Surgical and restorative techniques that can reduce the loss of hard and soft tissues that often accompany implant placement are desirable. Achieving an esthetic outcome in tooth replacement and implant treatment requires a...

Two major training techniques for wireless channels are time division multiplexed (TDM) training and superimposed training. For the TDM schemes with regular periodic placements (RPP), the closedform expression for the steady-state minimum mean square error (MMSE) of channel estimate is obtained as a function of placement for Gauss-Markov flat fading channels. We then show that, among all period...
