OntoCAT - an integrated programming toolkit for common ontology application tasks

OntoCAT provides high level abstraction for interacting with ontology resources including local ontology files in standard OWL and OBO formats (via OWL API) and public ontology repositories: EBI Ontology Lookup Service (OLS) and NCBO BioPortal. Each resource is wrapped behind easy to learn Java, Bioconductor/R and REST web service commands enabling reuse and integration of ontology software efforts despite variation in technologies

THE RAILWAY TO THE PACIFIC OCEAN (FOR THE 100-TH ANNIVERSARY OF THE TRANS-SIBERIAN RAILWAY)

The article gives a short description of the history of construction of the Trans-Siberian Railway. It covers the situation on Russia’s railways in the second half of the 19th century and debatable questions related to the selection of railway alignment, its function and financing of construction.

The formation of the methodology for the economic optimization of managerial decisions on transport

The urgency of the development of transport communications and the need to optimize their work, to develop a methodology for the study of transport as a specific industry has been substantiated. The issues of emergence and evolution of methods of economic research in transport in the context of general scientific methodology at various historical stages of development of domestic and foreign science have been considered. The characteristic of views of domestic and foreign scientists and experts on formal and substantial-essential methods of research has been given. The basic principles of a systematic approach to solving complex scientific and practical problems in the fieldof transport have been outlined

Coefficients Quantization at Off-axis Digital Hologram Wavelet Compression

Digital holographic information is compressed for storage of 2D- or 3D-objects amplitude and phase distributions, fast transmission, analyzing and displaying of these data. In this paper features of application of wavelet transforms for off-axis digital holograms compression are considered. The combined technique based on zero and twin orders elimination, wavelet compression of the amplitude and phase components of obtained Fourier spectrum and further additional compression of wavelet coefficients by thresholding and quantization is analyzed. Numerical experiments on reconstruction of images from the compressed holograms are performed. The comparative analysis of applicability of various wavelets and additional quantization of coefficients is performed. Obtained results demonstrate possibility of 180 and more times compression using iterative and noniterative methods of coefficients quantization and threshold zeroing less 80% of wavelet coefficients. Keywords: digital holography, hologram compression, wavelets, quantization, thresholding, digital image processing
