    Get PDF
    We report here on an investigation of astronomical plate archives and tests of the scanning devices for digitization of archival astronomical plates. These archives represent huge database of historical astronomical data, astrometric, photometric, and spectroscopic, with many applications in modern astrophysics

    Radio Sensor for Monitoring of UMTS Mobile Terminals

    Get PDF
    Relatively simple and low-cost radio sensor for monitoring of 3rd generation (3G) UMTS mobile terminals (i.e., phones) has been designed and practically tested. The main purpose of this sensor is to serve as an extending module that can be installed into systems used for monitoring of standard 2nd generation (2G) GSM and DCS mobile phones in highly guarded buildings and areas. Since the transmitted powers of UMTS mobile terminals can be very low in relation to GSM and DCS specifications, the new UMTS sensor is based on a highly sensitive receiver and additional signal processing. The radio sensor was practically tested in several scenarios representing worst-case mobile terminal - base station relations. The measured detection ranges attain values from approx. 11 m inside of rooms to more than 30 m in corridors, which seems to be sufficient for the expected application. Results of all performed tests correspond fairly well with the presented theoretical descriptions. An extended version of the radio sensor can be used for monitoring of mobile terminals of all existing voice or data formats

    Fish eye optics

    We report on small student (high school) project of the Czech Academy of Sciences dealing with animal (fish) eyes and possible application in science and technology. Albeit most fishes have refractive eyes, the recent discoveries confirm that some fishes have reflective eyes with strange arrangements as well

    A novel method for identifying Fast Optical Transients on astronomical archival plates

    Get PDF
    We report on a novel method to identify brief optical transients (OTs) on astronomical archival photographic plates. This method does not require identification of all objects and their comparison with the catalogue, but rely solely on the information included in the particular plate itself

    Strategic Planning and Public Opinion Survey

    Get PDF
    Strategic Planning is a creative, practical planning process for community change. Community Strategic Planning produces a visionary statement of what the community wants to be 10 to 20 years in the future. There is no one ideal strategic planning process that has worked for all communities and community groups. Different communities have successfully used a variety of processes. The article describes methods important for evolvement of the situation analysis, particularly the method of representative public opinion survey that provides basis for SWOT analysis and formulation of the strategic goals. The method reflecting public’s attitudes, values, and beliefs regarding community development is demonstrated on the example of two cities located in the Eastern part of the Slovak Republic - Košice and Spišská Nová Ves. Key words: Community Strategic Planning, Community Needs Analysis, City and Place Marketing, Strategic Planning Methodology, Public Opinion Survey, Questionnaires design.
