ETH NO. 17671 Proofs for the Working Engineer A dissertation submitted to ETH ZURICH for the degree of Doctor of Sciences presented by Farhad Dinshaw Mehta Master of Science, Technische Universit¨atM¨unchen Bachelor of Technology, Indian Institute of Technology Delhi born 11.01.1980 citizen of India accepted on the recommendation of Prof. Jean-Raymond Abrial Prof. Peter M¨uller Prof. Cliff Jones 2008 Abstract Over the last couple of decades the advantages of including formal proof within the development process for computer based systems has become in- creasingly clear. This has lead to a plethora of logics and proof tools that propose to fulfill this need. Nevertheless, the inclusion of theorem proving within the development process, even in domains where clear benefits can be expected, is rather an exception than the rule. One of the main goals of the formal methods endeavour is to bring the ac- tivity of formal theorem proving closer to the engineer developing computer based systems. This thesis makes some important practical contributions towards realising this goal. It hopes to shows that proper tool support can not only ease theorem proving, but also strenghten its role as a design aid. It shows that it is feasible to integrate interactive proof within a reactive development environment for formal systems. -
DISSERTATION Concepts for Scientific Computing
DISSERTATION Concepts for Scientific Computing ausgefuhrt¨ zum Zwecke der Erlangung des akademischen Grades eines Doktors der technischen Wissenschaften eingereicht an der Technischen Universitat¨ Wien Fakultat¨ fur¨ Elektrotechnik und Informationstechnik von RENE´ HEINZL Rosensteingasse 7-9/2 A-1160 Wien, Osterreich¨ Matr. Nr. 9826031 geboren am 6. September 1977, Wien Wien, im Juli 2007 Abstract Scientific computing has traditionally been concerned with numerical issues such as the convergence of discrete approximations to partial differential equations, the stability of integration methods for time- dependent systems, and the computational efficiency of software implementations of these numerical methods. While computer performance is steadily increasing the additional complexity of these simulation models easily outgrows this gain in computational power. It is therefore of utmost importance to employ the latest techniques of software development to obtain high performance and thereby ensure adequate simulation times even for complex problems. As a consequence the development of high performance simulation software is quite challenging. Originating in the field of technology computer aided design as an important and complex area of sci- entific computing, this work is motivated by the fact, that different concepts were developed during the last decades for the field of scientific computing. The great diversity of physical phenomena present in semiconductor devices themselves and in the processes involved in their manufacture make the field of TCAD extremely challenging. Each of the phenomena can be described by differential equations of vary- ing complexity. The development of several different discretisation schemes has been necessary in order to best model the underlying physics and to accommodate the mathematical peculiarities of each of these equations while transferring them to the discrete world of digital computing. -
HAIL: an Algorithm for the Hardware Accelerated Identification of Languages, Master's Thesis, May 2006
Washington University in St. Louis Washington University Open Scholarship All Computer Science and Engineering Research Computer Science and Engineering Report Number: WUCSE-2006-36 2006-01-01 HAIL: An Algorithm for the Hardware Accelerated Identification of Languages, Master's Thesis, May 2006 Charles M. Kastner This thesis examines in detail the Hardware-Accelerated Identification of Languages (HAIL) project. The goal of HAIL is to provide an accurate means to identify the language and encoding used in streaming content, such as documents passed over a high-speed network. HAIL has been implemented on the Field-programmable Port eXtender (FPX), an open hardware platform developed at Washington University in St. Louis. HAIL can accurately identify the primary languages and encodings used in text at rates much higher than what can be achieved by software algorithms running on microprocessors.

Personal Computing
Recent History of Computers: Machines for Mass Communication Waseda University, SILS, Science, Technology and Society (LE202) The communication revolution ‚ In the first period of the history of computers, we see that almost all development is driven by the needs and the financial backing of large organizations: government, military, space R&D, large corporations. ‚ In the second period, we will notice that the focus is now shifting to small companies, individual programers, hobbyists and mass consumers. ‚ The focus in the first period was on computation and control. In the second period, it is on usability and communication. ‚ A mass market for computers was created, through the development of a user-friendly personal computer.

Exploring Student Perceptions About the Use of Visual Programming
Exploring student perceptions about the use of visual programming environments, their relation to student learning styles and their impact on student motivation in undergraduate introductory programming modules Maira Kotsovoulou (BSc, MSc) July 2019 This thesis is submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy. Department of Educational Research, Lancaster University, UK. Exploring student perceptions about the use of visual programming environments, their relation to student learning styles and their impact on student motivation in undergraduate introductory programming modules Maira Kotsovoulou (BSc, MSc) This thesis results entirely from my own work and has not been offered previously for any other degree or diploma. The word count is 57,743 excluding references. Signature ........................................................ Maira Kotsovoulou (BSc, MSc) Exploring student perceptions about the use of visual programming environments, their relation to student learning styles and their impact on student motivation in undergraduate introductory programming modules Doctor of Philosophy, July 2019 Abstract My research aims to explore how students perceive the usability and enjoyment of visual/block-based programming environments (VPEs), to what extent their learning styles relate to these perceptions and finally to what extent these tools facilitate student understanding of basic programming constructs and impact their motivation to learn programming. My overall methodological approach is a case study that explores the nature of potential benefits to using a VPE in an introductory programming module, within the specific context of an English-speaking institution of higher learning in Southern Europe. Part 1 of this research is a pilot study, which uses participatory action research as a methodological practice to identify which visual programming environment will be selected for the main study. -
Fiendish Designs
Fiendish Designs A Software Engineering Odyssey © Tim Denvir 2011 1 Preface These are notes, incomplete but extensive, for a book which I hope will give a personal view of the first forty years or so of Software Engineering. Whether the book will ever see the light of day, I am not sure. These notes have come, I realise, to be a memoir of my working life in SE. I want to capture not only the evolution of the technical discipline which is software engineering, but also the climate of social practice in the industry, which has changed hugely over time. To what extent, if at all, others will find this interesting, I have very little idea. I mention other, real people by name here and there. If anyone prefers me not to refer to them, or wishes to offer corrections on any item, they can email me (see Contact on Home Page). Introduction Everybody today encounters computers. There are computers inside petrol pumps, in cash tills, behind the dashboard instruments in modern cars, and in libraries, doctors’ surgeries and beside the dentist’s chair. A large proportion of people have personal computers in their homes and may use them at work, without having to be specialists in computing. Most people have at least some idea that computers contain software, lists of instructions which drive the computer and enable it to perform different tasks. The term “software engineering” wasn’t coined until 1968, at a NATO-funded conference, but the activity that it stands for had been carried out for at least ten years before that. -
Learning to Code
PART ILEARNING TO CODE How Important is Programming? “To understand computers is to know about programming. The world is divided… into people who have written a program and people who have not.” Ted Nelson, Computer Lib/Dream Machines (1974) How important is it for you to learn to program a computer? Since the introduction of the first digital electronic computers in the 1940s, people have answered this question in surprisingly different ways. During the first wave of commercial computing—in the 1950s and 1960s, when 1large and expensive mainframe computers filled entire rooms—the standard advice was that only a limited number of specialists would be needed to program com- puters using simple input devices like switches, punched cards, and paper tape. Even during the so-called “golden age” of corporate computing in America—the mid- to late 1960s—it was still unclear how many programming technicians would be needed to support the rapid computerization of the nation’s business, military, and commercial operations. For a while, some experts thought that well-designed computer systems might eventually program themselves, requiring only a handful of attentive managers to keep an eye on the machines. By the late 1970s and early 1980s, however, the rapid emergence of personal computers (PCs), and continuing shortages of computer professionals, shifted popular thinking on the issue. When consumers began to adopt low-priced PCs like the Apple II (1977), the IBM PC (1981), and the Commodore 64 (1982) by the millions, it seemed obvious that ground-breaking changes were afoot. The “PC Revolution” opened up new frontiers, employed tens of thousands of people, and (according to some enthusiasts) demanded new approaches to computer literacy. -
