Positional analysis is considered an important tool in the analysis of social networks. It involves partitioning of the set of actors into subsets such that actors in a subset are similar in their structural relationships with other actors. Traditional methods of positional analysis such as structural equivalence, regular equivalence, and equitable partitions are either too strict or too generi...

In this study, we propose an indoor navigation system that utilizes visible light communication technology, which employs LED lights and a geomagnetic correction method, aimed at supporting visually impaired people who travel indoors. To verify the effectiveness of this system, we conducted an experiment targeting visually impaired people. Although acquiring accurate positional information and ...

This study consists of a general review of benign paroxysmal positional vertigo and nystagmus. The main etiopathogenesis, diagnosis, and treatments are evoked. The author describes his experience on the subject.

To pinpoint true positive single-nucleotide polymorphism (SNP) associations in a genome-wide association study (GWAS) of rheumatoid arthritis (RA), we categorize genetic loci by external knowledge. We test both the 'enrichment of associated loci' in a locus category and the 'combined association' of a locus category. The former is quantified by the odds ratio for the presence of SNP association...

Fusional languages have rich inflection. As a consequence, tagsets capturing their morphological features are necessarily large. A natural way to make a tagset manageable is to use a structured system. In this paper, we present a positional tagset for describing morphological properties of Russian. The tagset was inspired by the Czech positional system (Hajič, 2004). We have used preliminary ve...

Positioning technology is a core component of the ubiquitous computing environment. Radio Frequency IDentificaiton (RFID) is recognized as a powerful means of replacing not only barcodes for product identification but also conventional positioning systems in unfavorable situations such as indoor and obstacle-laden sites. The objective of this study was to determine the design parameters of an R...
