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. -

“Scrap Your Boilerplate” Reloaded
“Scrap Your Boilerplate” Reloaded Ralf Hinze1, Andres L¨oh1, and Bruno C. d. S. Oliveira2 1 Institut f¨urInformatik III, Universit¨atBonn R¨omerstraße164, 53117 Bonn, Germany {ralf,loeh}@informatik.uni-bonn.de 2 Oxford University Computing Laboratory Wolfson Building, Parks Road, Oxford OX1 3QD, UK [email protected] Abstract. The paper “Scrap your boilerplate” (SYB) introduces a com- binator library for generic programming that offers generic traversals and queries. Classically, support for generic programming consists of two es- sential ingredients: a way to write (type-)overloaded functions, and in- dependently, a way to access the structure of data types. SYB seems to lack the second. As a consequence, it is difficult to compare with other approaches such as PolyP or Generic Haskell. In this paper we reveal the structural view that SYB builds upon. This allows us to define the combinators as generic functions in the classical sense. We explain the SYB approach in this changed setting from ground up, and use the un- derstanding gained to relate it to other generic programming approaches. Furthermore, we show that the SYB view is applicable to a very large class of data types, including generalized algebraic data types. 1 Introduction The paper “Scrap your boilerplate” (SYB) [1] introduces a combinator library for generic programming that offers generic traversals and queries. Classically, support for generic programming consists of two essential ingredients: a way to write (type-)overloaded functions, and independently, a way to access the structure of data types. SYB seems to lacks the second, because it is entirely based on combinators. -

Saarbrücken, June 6, 2017 (Piotr Danilewski) Zusammenfassung Die Sprachen prägen die Denkweise. Das ist die Tatsache für die gesprochenen Sprachen aber auch für die Programmiersprachen. Da die Computer immer wichtiger in jedem Aspekt des menschlichen Lebens sind, steigt der Bedarf um entsprechend neue Konzepte in den Programmiersprachen auszudrücken. Jedoch, damit unsere Denkweise sich weiterentwicklen könnte, müssen sich auch die Programmiersprachen weiterentwickeln. Aber welche Hilfsmittel gibt es um die Programmiersprachen zu schaffen und aufzurüsten? Wie kann man Entwickler ermutigen damit sie eigene Sprachen definieren, die dem Bereich in dem sie arbeiten am besten passen? Heutzutage gibt es zwei Methoden. -
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. -
On Specifying and Visualising Long-Running Empirical Studies
On Specifying and Visualising Long-Running Empirical Studies Peter Y. H. Wong and Jeremy Gibbons Computing Laboratory, University of Oxford, United Kingdom fpeter.wong,[email protected] Abstract. We describe a graphical approach to formally specifying tem- porally ordered activity routines designed for calendar scheduling. We introduce a workflow model OWorkflow, for constructing specifications of long running empirical studies such as clinical trials in which obser- vations for gathering data are performed at strict specific times. These observations, either manually performed or automated, are often inter- leaved with scientific procedures, and their descriptions are recorded in a calendar for scheduling and monitoring to ensure each observation is carried out correctly at a specific time. We also describe a bidirectional transformation between OWorkflow and a subset of Business Process Modelling Notation (BPMN), by which graphical specification, simula- tion, automation and formalisation are made possible. 1 Introduction A typical long-running empirical study consists of a series of scientific proce- dures interleaved with a set of observations performed over a period of time; these observations may be manually performed or automated, and are usually recorded in a calendar schedule. An example of a long-running empirical study is a clinical trial, where observations, specifically case report form submissions, are performed at specific points in the trial. In such examples, observations are interleaved with clinical interventions on patients; precise descriptions of these observations are then recorded in a patient study calendar similar to the one shown in Figure 1(a). Currently study planners such as trial designers supply information about observations either textually or by inputting textual infor- mation and selecting options on XML-based data entry forms [2], similar to the one shown in Figure 1(b). -

Kind Theory Thesis by Joseph R. Kiniry In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy California Institute of Technology Pasadena, California 2002 (Defended 10 May 2002) ii © 2002 Joseph R. Kiniry All Rights Reserved iii Preface This thesis describes a theory for representing, manipulating, and reasoning about structured pieces of knowledge in open collaborative systems. The theory's design is motivated by both its general model as well as its target user commu- nity. Its model is structured information, with emphasis on classification, relative structure, equivalence, and interpretation. Its user community is meant to be non-mathematicians and non-computer scientists that might use the theory via computational tool support once inte- grated with modern design and development tools. This thesis discusses a new logic called kind theory that meets these challenges. The core of the work is based in logic, type theory, and universal algebras. The theory is shown to be efficiently implementable, and several parts of a full realization have already been constructed and are reviewed. Additionally, several software engineering concepts, tools, and technologies have been con- structed that take advantage of this theoretical framework. These constructs are discussed as well, from the perspectives of general software engineering and applied formal methods. iv Acknowledgements I am grateful to my initial primary adviser, Prof. K. Mani Chandy, for bringing me to Caltech and his willingness to let me explore many unfamiliar research fields of my own choosing. I am also appreciative of my second adviser, Prof. Jason Hickey, for his support, encouragement, feedback, and patience through the later years of my work. -
On a New Notion of Partial Refinement
On a New Notion of Partial Refinement Emil Sekerinski Tian Zhang McMaster University McMaster University Hamilton, Canada Hamilton, Canada [email protected] [email protected] Formal specification techniques allow expressing idealized specifications, which abstract from re- strictions that may arise in implementations. However, partial implementations are universal in soft- ware development due to practical limitations. Our goal is to contribute to a method of program refinement that allows for partial implementations. For programs with a normal and an exceptional exit, we propose a new notion of partial refinement which allows an implementation to terminate ex- ceptionally if the desired results cannot be achieved, provided the initial state is maintained. Partial refinement leads to a systematic method of developing programs with exception handling. 1 Introduction In software development, specifications are meant to be concise by stating abstractly only the intention of a program rather than elaborating on a possible implementation. However, practical restrictions can prevent idealized specifications from being fully implemented. In general, there are three sources of partiality in implementations: there may be inherent limitations of the implementation, some features may intentionally not (yet) be implemented, or there may be a genuine fault. As an example of inherent limitations of an implementation, consider a class for the analysis of a collection of integers. The operations are initialization, inserting an integer, and summing all its elements. Assume that int is a type for machine-representable integers, bounded by MIN and MAX, and machine arithmetic is bounded, i.e. an overflow caused by arithmetic operations on int is detected and raises an exception, as available in x86 assembly language [11] and .NET [20]. -
