This paper deals with the automatic selection and configuration of base station sites for mobile cellular networks. An optimization framework based on simulated annealing is used for site selection and for base-station configuration. Realistic path-loss estimates incorporating terrain data are used. The configuration of each base station involves selecting antenna type, power control, azimuth, ...

In the task of question answering, Memory Networks have recently shown to be quite effective towards complex reasoning as well as scalability, in spite of limited range of topics covered in training data. In this paper, we introduce Factual Memory Network, which learns to answer questions by extracting and reasoning over relevant facts from a Knowledge Base. Our system generate distributed repr...

A bstract We propose a framework where phase transition associated with gauge symmetry breaking that occurs (not far) above the electroweak scale sets stage for baryogenesis similar to in Standard Model. concrete realization utilizes of SU(2) R × U(1) X → Y . New chiral fermions charged under extended have nonzero lepton numbers, which makes B − L anomalous. The new sector contains large flavor...

objective: today, aids is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. dna vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. however, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccine...

The general goal of music signal decomposition is to represent the music structure into a note level to provide valuable semantic features for further music analysis tasks. In this paper, we propose a new method to sparsely decompose the music signal onto a MIDI dictionary made of musical notes. Statistical music knowledge is further integrated into the whole sparse decomposition process. The p...

 We investigate the existence of some‎ ‎large sets of size nine‎. ‎The large set $LS[9](2,5,29)$ is constructed and‎ ‎existence of the family $LS[9](2,5,27l+j)$ for $lgeq 1, ‎2leq‎ ‎j

The Semantic Web is a candidate for the next generation of the World Wide Web. It is anticipated that the number of metadata written in RDF (Resource Description Framework) and RDF Schema will increase as the Semantic Web becomes popular. In such a situation, demand for querying metadata described with RDF and RDF Schema will also increase, and therefore effective query retrieval of RDF data is...

Optimal path planning problems for rigid and deformable (bendable) cuboid robots are considered by providing an analytic safety constraint using generalized Lp norms. For regular cuboid robots, level sets of weighted Lp norms generate implicit approximations of their surfaces. For bendable cuboid robots a weighted Lp norm in polar coordinates implicitly approximates the surface boundary through...

With the rapid development of high-speed railway and the changes of the tourists’ requirement, it is imperative to the integrate advantages of aviation and rail. This paper constructs the air-rail integration model based on the current development situation and characteristics of Chinese railways. In allusion to the search problem of connecting path in air-rail integration network, a constraine...

{gaojun, dqyang, tjwang }@ pku.edu.cn Abstract XML query rewriting in the distributed computing environment receives high attention recently. Different from existing work, we focus on the query rewriting in the cases that there are multiple views at the client side. We design two data structures to manage the multiple XML views. MPTree is constructed from the main path of the XML views to gener...
