With cloud-based data management gaining more ground by day, the problem of estimating the progress of MapReduce queries in the cloud is of paramount importance. This problem is challenging to solve for two reasons: i) cloud is typically a large-scale heterogeneous environment, which requires progress estimation to tailor to non-uniform hardware characteristics, and ii) cloud is often built wit...

A new robust method to segment images based on Markov Random Fields (MRF) is presented. The algorithm does not require the number of classes or regions K as input, which is normally difficult to determine in advance. There is also no need for an initial estimate obtained by an algorithm such as K-means. Further, each region is connected during the whole segmentation process leading to more reli...

IEEE 802.11e provides the guaranteed quality of service (QoS) by providing different transmission priorities. IEEE 802.11e improves the media access control layer of IEEE 802.11 to satisfy the different QoS requirements by introducing two channel access functions: the enhanced distributed channel access (EDCA) and HCF controlled channel access (HCCA). Therefore, most devices support different t...

Even reaching the so-called 'ordinary' poor would entail challenges of electrical power, telecommunications connectivity, human resources infrastructure, and the like. Reaching the 'poorest' would be even more difficult due to wider gaps in those parameters just mentioned (DotForce, 2001). But, in addition, there would be the parameter of limitations in the human skill competencies of this targ...

Prospective elasticity analyses have been used to aid in the management of fished species and the conservation of endangered species. Elasticities were examined for deterministic size-based matrix models of red abalone, Haliotis rufescens, and white abalone, H. sorenseni, to evaluate which size classes influenced population growth (lambda) the most. In the red abalone matrix, growth transitions...
