The concept of femtocell that operates in licensed spectrum to provide home coverage has attracted interest in the wireless industry due to high spatial reuse, and extensive deployments of femtocells is expected in the future. In this paper, we consider the scenario that a femtocell service provider (FSP) expects to rent spectrum from the coexisting macrocell service provider (MSP) to serve its end...
In order to understand the chemical characteristics of wet precipitation in Toyama, Japan, the rainwater samples were collected during 3 – 8, 2008, the pH value, electrical conductivity and major-water soluble ions were measured. The result showed that the average pH of rainwater was observed to be 6.39, ranging from 5.77 to 6.62, indicating the precipitation in Toyama had been acidified. The annual...
Understanding the genotype-phenotype association is a fundamental problem in genetics. A major open problem in mapping complex traits is identifying a set of interacting genetic variants (such as single nucleotide polymorphisms or SNPs) that influence disease susceptibility. Logic regression (LR) is a statistical approach that has been proposed to model interactions of SNPs. Several LR-based association...
This paper presents a method for the measurement of nanoscale surface patterns produced by two-beam laser interference lithography (LIL). In the work, the combination of the Hough fitting and the least-squares fitting was first used to fit the edges of the fringe patterns and measure the slopes and periods of them in computer simulation, and then it was also used to inspect the nanoscale surface patterns...
This paper introduces a method for the determination of the slope and period of oblique and equi-spaced fringes by pattern correlation. In the method, two pairs of image patches in two different regions of a fringe pattern are selected for pattern correlation calculations, and the phase shift between the two selected regions of the fringe pattern is obtained from the phase curves computed with the...
Social media, e.g. Weblog and Internet forum, generate rich historical textual datasets which record lots of valuable events. Automatic event detection tries to discover important and interesting events and their related documents. Existing solutions to event detection, however, are mostly proposed for high quality news stories and may not work well when they are applied to noisy social media datasets,...
A fast and effective fade detection algorithm is proposed in this paper, which directly operates in compressed domain and suitable for real-time implementation. By analyzing the prediction directions of B frames, which are revealed in the macroblock types, the candidate fades can be found. Then, uncommon intracoded macroblocks of the P frame can be applied as an indicator of fade. As a result, locating...
