CHALLENGES TO ACADEMIC CIO IN MANAGING INFORMATION TECHNOLOGY IN UNIVERSITIES

  • TITLE: CHALLENGES TO ACADEMIC CIO IN MANAGING INFORMATION TECHNOLOGY IN UNIVERSITIES
  • AUTHOR(S): B. Bojinov
  • ABSTRACT: This study, based on theoretical and empirical study aims, to systematize and summarize the key challenges in CIO managers in the management of modern information technologies in universities. The study asserts the author's thesis that the effective management of information technology in modern universities require specific mix of technical, educational, managerial skills to enable CIO manager to achieve the strategic goals of the university, combining modern business, IT and educational approaches in terms of resource scarcity and increased competitive pressure. The analysis of the challenges facing IT management in universities used data from existing analyzes and research of leading specialized consulting companies, publicly available data on the investigated problems, results of a survey on the topic (31.10-30.11.2016), as well as information from interviews and informal talks with representatives of the academic IT management and personal experiences of the author as managing the processes in the Academy of Economics in the period 2007-2015 -line survey was conducted through Google Forms tool of Google Docs, and the data are processed and presented in the form of tables and charts by using MS Office Excel 2016.

TESTING STAND DESIGNED FOR ELEVATING MECHANISMS - WIRE ROPE AND CHAIN ELECTRIC HOISTS, AND WINCHES

  • TITLE: TESTING STAND DESIGNED FOR ELEVATING MECHANISMS - WIRE ROPE AND CHAIN ELECTRIC HOISTS, AND WINCHES
  • AUTHOR(S): I. Balashev, M. Penev, I. Stoianov
  • ABSTRACT: The stand is designed for testing of the elevating mechanisms of wire rope and chain electric hoists, and winches. The necessary pressure depending on the loading capacity of the elevating mechanism is accomplished by two hydraulic cylinders via their hydraulic p ressure adjustments made by an adjustable throttle. The stand is designed for testing of elevating mechanisms with load-lifting capacity up to Q=100kN.

ABOUT THE CONSTRUCTIONAL FEATURES OF WATERJET-LASER PROFILED PERFORATION OF THIN-SHEET METAL BLANKS

  • TITLE: ABOUT THE CONSTRUCTIONAL FEATURES OF WATERJET-LASER PROFILED PERFORATION OF THIN-SHEET METAL BLANKS
  • AUTHOR(S): V.Y. Kholodnyi, A.F.Salenko, A. Bal, S.P. Melnichuk
  • ABSTRACT: Methods which use to produce specialized holes by the process of perforation of aluminum-magnesium foil are considered. Defects of mechanical and laser perforation of aluminum foil are shown. A fundamentally new design of waterjet-laser head are represented. This construction allows obtaining specialized holes comparable to the profile of the jet stream that is formed by an annular nozzle. Using FlowVision software, mathematical modeling of liquid stream through cavities of newly projected waterjet-laser head, the special feature ofwhich is the presence of ring nozzle head and valve type device, was run which allows liquid inlet into the cavity of the head, using the required amount of points (from 1 to 6 channels of working liquid inlet). Velocity profiles are achieved, the analysis of which allows making conclusions about quality appreciation of inequality of speed fields from the amount of liquid input channels.

STAND FOR TESTING OF COUPLINGS WITH NON METALLIC ELASTIC ELEMENTS

  • TITLE: STAND FOR TESTING OF COUPLINGS WITH NON METALLIC ELASTIC ELEMENTS
  • AUTHOR(S): K. V. Krystev
  • ABSTRACT: A stand for testing of couplings with non metallic elastic elements, in which the elements are made from different kind of rubber (different Shor hardness) is presented in this paper. Methods of testing are given too. It gives possibilities to make static and dynamic testing of the couplings and to determine their static and dynamic characteristics.
