We develop a scalable cell-level analytical model for multi-cell infrastructure IEEE 802.11 WLANs under a so-called Pairwise Binary Dependence (PBD) condition. The PBD condition is a geometric property under which the relative locations of the nodes inside a cell do not matter and the network is free of hidden nodes. For the cases of saturated nodes and TCP-controlled long-file downloads, we pr...

Effective robot programming by demonstration requires the availability of multiple demonstrations to learn about all relevant aspects of the demonstrated skill or task. Typically, a human teacher must demonstrate several variants of the desired task to generate a sufficient amount of data to reliably learn it. Here a problem often arises that there is a large variability in the speed of executi...

Programming by demonstration (PBD) utilizes a human teacher to train a computer system to perform tasks within that system. This technique effectively improves productivity for many tasks, in many domains. Many tasks are repetitive in nature; these can be learned by PBD by recognizing the repetitions and generalizing these to iterative programs. We present a domain-independent approach to itera...

background religious coping is known as a main resource influencing how individuals cope with the complications and stressors of chronic disease. objectives the aim of this study was to assess the relationship between religious coping and quality of life among hemodialysis patients. methods this cross-sectional study was conducted in qom, iran, from june 2012 to july 2013. ninety-five end-stage...

In robot programming by demonstration, we hypothesize that in a class of procedural tasks where the end goal primarily consists of the states of objects that are external to a task performer, one can significantly reduce complexity of a robot learner by not processing a human demonstrator’s motions at all. In this class of tasks, object behaviors are far more critical than human behaviors. Base...

Prototypes of the Fermi system have been used to read out a prototype of the Atlas hadron calorimeter in a beam test at the CERN SPS. The Fermi read-out system, using a compressor and a sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. Signal processing techniques have bee...
