In 2012 the multi-beam feed array became operational on the BSA FIAN radio telescope. As of July 2014 it is capable of 24-hour observation using 96 beams in declination of -8 to +42 degrees in the 109-111.5 MHz frequency band. The number of frequency bands range from 6 to 32, while the time constants range from 0.1 to 0.0125 sec. While receiving in 32 band mode (plus one common band) with a time constant of 12.5 ms (80 times per second), 33x96x80 four-byte data samples are produced per second, which equates to a daily data production of 87.5 gigabytes (up to 32 terabytes yearly). This data is an enormous opportunity for both short and long-term monitoring of various classes of radio sources (including radio transients), space weather and the Earth's ionosphere monitoring, search for different classes of radio sources, etc. The base goals of our work are: a) To obtain new scientific data on different classes of discrete radio sources, the construction thereof physical models and evolutions - obtained on the basis of continuous, round-the-clock monitoring of the radio sky in the 109-111.5 MHz frequency band and cross-analysis of data from third-party surveys of other frequencies. b) To launch data streaming on various types of high-performance computing systems, including creating a public system of distributed computing for thousands of users on the basis of BOINC technology. The BOINC client for astronomical data from the monitoring surveys of large parts of the entire sky almost has no analogies.
The Handbook of CO₂ in Power Systems' objective is to include the state-of-the-art developments that occurred in power systems taking CO₂ emission into account. The book includes power systems operation modeling with CO₂ emissions considerations, CO₂ market mechanism modeling, CO₂ regulation policy modeling, carbon price forecasting, and carbon capture modeling. For each of the subjects, at least one article authored by a world specialist on the specific domain is included.
The article is based upon the fact that the growing demand for master data management systems has not yet produced a commonly accepted metodology for their design and development/ The article offers two mathematical models? that allow a master data management systems designer a way to formally describe their system before development and verify the system quality by measurements? unique to master data management systems.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
