A Zahlensysteme
A Zahlensysteme Außer dem Dezimalsystem sind das Dual-,dasOktal- und das Hexadezimalsystem gebräuchlich. Ferner spielt das Binär codierte Dezimalsystem (BCD) bei manchen Anwendungen eine Rolle. Bei diesem sind die einzelnen Dezimalstellen für sich dual dargestellt. Die folgende Tabelle enthält die Werte von 0 bis dezimal 255. Be- quemlichkeitshalber sind auch die zugeordneten ASCII-Zeichen aufgeführt. dezimal dual oktal hex BCD ASCII 0 0 0 0 0 nul 11111soh 2102210stx 3113311etx 4 100 4 4 100 eot 5 101 5 5 101 enq 6 110 6 6 110 ack 7 111 7 7 111 bel 8 1000 10 8 1000 bs 9 1001 11 9 1001 ht 10 1010 12 a 1.0 lf 11 101 13 b 1.1 vt 12 1100 14 c 1.10 ff 13 1101 15 d 1.11 cr 14 1110 16 e 1.100 so 15 1111 17 f 1.101 si 16 10000 20 10 1.110 dle 17 10001 21 11 1.111 dc1 18 10010 22 12 1.1000 dc2 19 10011 23 13 1.1001 dc3 20 10100 24 14 10.0 dc4 21 10101 25 15 10.1 nak 22 10110 26 16 10.10 syn 430 A Zahlensysteme 23 10111 27 17 10.11 etb 24 11000 30 18 10.100 can 25 11001 31 19 10.101 em 26 11010 32 1a 10.110 sub 27 11011 33 1b 10.111 esc 28 11100 34 1c 10.1000 fs 29 11101 35 1d 10.1001 gs 30 11110 36 1e 11.0 rs 31 11111 37 1f 11.1 us 32 100000 40 20 11.10 space 33 100001 41 21 11.11 ! 34 100010 42 22 11.100 ” 35 100011 43 23 11.101 # 36 100100 44 24 11.110 $ 37 100101 45 25 11.111 % 38 100110 46 26 11.1000 & 39 100111 47 27 11.1001 ’ 40 101000 50 28 100.0 ( 41 101001 51 29 100.1 ) 42 101010 52 2a 100.10 * 43 101011 53 2b 100.11 + 44 101100 54 2c 100.100 , 45 101101 55 2d 100.101 - 46 101110 56 2e 100.110 . -

REFRAMING INTERACTIVE DIGITAL NARRATIVE: TOWARD AN INCLUSIVE OPEN-ENDED ITERATIVE PROCESS FOR RESEARCH AND PRACTICE A Dissertation Presented to The Academic Faculty By Hartmut Koenitz In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy in Digital Media Georgia Institute of Technology August, 2010 Copyright © Hartmut Andreas Koenitz 2010 Reframing Interactive Digital Narrative: Toward An Inclusive Open-Ended Iterative Process For Research And Practice Approved by: Dr. Janet Murray, Advisor Dr. Kenneth Knoespel School of Literature, Communication Ivan Allen College and Culture Georgia Institute of Technology Georgia Institute of Technology Dr. Mads Haahr Dr. Jay Bolter Department of Computer Science School of Literature, Communication Trinity College Dublin and Culture Georgia Institute of Technology Date Approved: June 30, 2010 Dr. Celia Pearce School of Literature, Communication and Culture Georgia Institute of Technology It is a waste of energy and resources to make applications that merely imitate media that exist in other forms, such as print, television, and film. Pamela Jennings, 1996 To my Parents ACKNOWLEDGEMENTS First and foremost I want to acknowledge the help, dedication and commitment of my advisor Janet Murray. Her relentless criticism and simultaneous encouragement sharpened both my wit and the focus of my arguments. Jay Bolter gave me the courage to start this project and provided not only lucid intellectual advice, but also a shoulder to lean on and a voice of sanity in the darkest hours of this thesis. Celia Pearce gave me a new appreciation of games and encouraged me to include installation pieces I would have otherwise overlooked. Kenneth Knoespel always took my mind to exciting and unforeseen places and made me think outside the box. -

Anything else? SURA Workshop, May 2012 3 Introduction to Parallel Programming Concurrency or Parallelism? A concurrent program or algorithm is one where operations can occur at the same time. For instance, a simple integration, where numbers are summed over an interval. The interval can be broken into many concurrent sums of smaller sub-intervals. Concurrency is a property of the program. Parallel execution is when the concurrent parts are executed at the same time on separate processors. The distinction is subtle, but important. And, parallel execution is a property of the machine, not the program. SURA Workshop, May 2012 4 Introduction to Parallel Programming Concurrency or Parallelism? A system is said to be concurrent if it can support two or more actions in progress at the same time. A system is said to be parallel if it can support two or more actions executing simultaneously. -

Haiku (Operating System) from Wikipedia, the Free Encyclopedia
Haiku (operating system) From Wikipedia, the free encyclopedia Haiku is a free and open-source operating system compatible with the now discontinued BeOS. Its development began in Haiku 2001, and the operating system became self-hosting in 2008.[4] The first alpha release was made in September 2009, and the most recent was November 2012; development is ongoing as of 2017 with nightly releases. Haiku is supported by Haiku, Inc., a non-profit organization based in Rochester, New York, United States, founded in 2003 by former project leader Michael Phipps.[5] Contents 1 History 2 Technology 3 Package management Developer Haiku, Inc.

Video on Demand and Catch-Up TV in Europe
On-demand audiovisual services have mushroomed in Europe. Video on demand, catch- Video on up television and video sharing are vying for the consumer’s attention but are facing the problem of internet piracy at the same time. The landscape has become very fragmented demand and is developing very rapidly. Business models are being defined and are in some cases Video on merging with one another. The crisis on the advertising market and the limits imposed and on the development of the free services offered by the public broadcasters are leading to a growing interest in paid-for services, but the development of pay models is being catch-up TV impeded by piracy and it seems these services will not come into their own until on- demand offerings can be fully accessed on a television set instead of only on a computer demand in Europe screen or mobile telephone. The provision of access to VOD on a TV is thus becoming a very important issue and galvanising manufacturers and network operators into action. This report provides a complete and up-to-date picture of the different on-demand au- diovisual services and of how they fit into the strategy of the various types of player. It and is both concise and detailed and will be a useful tool for anyone seeking to understand the complexity of this evolving field. catch-up TV Set up in December 1992, the European Audiovisual Observatory’s mission is to gather European and distribute information on the audiovisual industry in Europe.

Development Tendencies of Programming Languages S.J
Journal of Engineering and Technology DEVELOPMENT TENDENCIES OF PROGRAMMING LANGUAGES S.J. Mahmudova* Department of Software Engineering, Institute of Information Technology of ANAS, Baku, Azerbaijan. ABSTRACT The study presents the information on software engineering (SE) and the knowledge spheres covered by SE. The development stages of programming and the problems encountered in this field are explored. Various programming languages are used to create software for problems. Programming is the process of developing software for a computer. One of the main goals of modern software engineering is to create software products for different problem-oriented areas and to ensure its effectiveness throughout the life cycle. In a broad spectrum, programming means the creation process of software. This includes analyzing and managing the issue, scheduling and designing the program, developing algorithms and data structures, and writing, executing, testing, documenting, configuring, completing and accompanying the program texts. The point is that although the programming languages are powerful and multifunctional, syntax for none of these languages is currently perfect and universal. Hence the programming languages are constantly developing. Broadcasting multi-core processors, cloud programming, portable techniques (digital video camera, music player, mobile phones, GPS navigators, Notebook, İpad, etc.) as well as distributed architecture have created new problems for manufacturers. The information on programming languages are presented, the comparative
