The paper describes a novel method of localizing line segments and estimating their start and end points. The lines are ordered within the image by detecting the orientation of straight edges. Image processing structure is considered which includes directional gradient processing for obtaining straight lines from edges and filtering of lines with the prescribed line slope. It permits to order lines of this slope according to their gradient values and their lengths. Extraction of a gradient line profile is used for start and end points estimation by thresholding. The problem considered is related to reduction of an original grey-level image to a set of geometric edge position parameters. This set may be used for construction primary features for image understanding and storing. It is also useful for a comparison of different images of the same scene and for finding the mutual points for images matching. Source

This paper examines the effects of food and commodity speculation on the basis of the current state of research. Countless econometric studies have yet to either conclusively confirm or deny the influence of speculation on prices. However, the influence of futures prices on the spot market prices can be derived if the excess demand in the futures market is high and persists for an extended period of time. Regulation is therefore required. © 2015, ZBW and Springer-Verlag Berlin Heidelberg. Source

An embedded system is normally adapted to a specific application and optimized for speed, power consumption and cost. In applications where power consumption and cost are important, embedded systems are typically very small. Because of the limited hardware resources of such a system it is normally not possible to utilize a real-time operating system - even though it would reduce development costs. This paper describes the inner principles of a real time operating system that is able to work with minimal resources and very effective power use. © 2014 IEEE. Source

Genome-Wide Association Studies are widely used to correlate phenotypic traits with genetic variants. These studies usually compare the genetic variation between two groups to single out certain Single Nucleotide Polymorphisms (SNPs) that are linked to a phenotypic variation in one of the groups. However, it is necessary to have a large enough sample size to find statistically significant correlations. Direct-To-Consumer (DTC) genetic testing can supply additional data: DTC-companies offer the analysis of a large amount of SNPs for an individual at low cost without the need to consult a physician or geneticist. Over 100,000 people have already been genotyped through Direct-To-Consumer genetic testing companies. However, this data is not public for a variety of reasons and thus cannot be used in research. It seems reasonable to create a central open data repository for such data. Here we present the web platform openSNP, an open database which allows participants of Direct-To-Consumer genetic testing to publish their genetic data at no cost along with phenotypic information. Through this crowdsourced effort of collecting genetic and phenotypic information, openSNP has become a resource for a wide area of studies, including Genome-Wide Association Studies. openSNP is hosted at http://www.opensnp.org, and the code is released under MIT-license at http://github.com/gedankenstuecke/snpr. © 2014 Greshake et al.

A novel process, for use on a production scale, is reported which allows the optimisation and analysis of ultra-thin interfacial properties of ultra-thin SiO2 to be controlled and characterised at an atomic level. These results provide a greatly improved insight into the correlation between conditions of preparation and the fundamentals of the process. This, in turn, allows optimisation of the Si/SiO2 interface, to meet increasingly demanding performance requirements. So widely used are nanotechnological assemblies, in line with increasing miniaturisation, that this technology is now virtually mandatory. Source
