Automation methods for huge amount of computations in grid environment and their applications in Ukrainian National Grid (UNG) are described. Proposed methods are based on asynchronous job submission and control. Methods has solved the problems of job data staging in, description preparing, job submission, job status monitoring and staging out results.(More)
Design and application of web service and desktop user client for working with medical DICOM-images in Ukrainian Grid infrastructure are described. Web-service provides transparent replication of data in grid storage elements. Client consists of graphical front-end, network back-end and provides functions of image anonymization-deanonymization, searching,(More)
Distributed database and analysis tools for electroencephalography (EEG) data archiving and procession in Ukrainian Grid Infrastructure were proposed, implemented and applied for separation of signal sources. The database is being populated with human scalp EEG and rat intracranial EEG data now. Resources consuming algorithms for removal of electromyogram(More)
Rainbow is the system for running hardware accelerated virtual machines with an interactive access capability as grid jobs submitted to the Advanced Resource Connector (ARC) [1] powered infrastructure. Methods for running virtual machine as a grid jobs as well as Rainbow architecture has been proposed and implemented for practical use in the Ukrainian(More)
Interactions of 9-methylguanine (m9Gua) with carboxylate ion of acetic acid (CH3COO-) and Na+ were studied by 1H NMR spectroscopy and ab initio quantum chemical calculations of the B3LYP/6-31++G(d,p) and B3LYP/6-311++G(d,p) levels of theory. Changes in the m9Gua 1H NMR spectrum in the presence of the equimolar amount of sodium acetate (NaAc), which in(More)
