Therefore, it is important to build verification tools systems. One software error, as simple as it may be, can that exhaustively check for as many classes of errors as cause the loss of an expensive mission, or lead to budget possible. Static program analysis is a verification technique overruns and crunched schedules. Unfortunately, traditional that identifies faults, or certifies the absence of faults, in verification methods cannot guarantee the absence of errors software without having to execute the program. Using the in software systems. Therefore, we have developed the CGS formal semantic of the programming language (C in our static program analysis tool, which can exhaustively analyze case), this technique analyses the source code of a program large C programs. CGS analyzes the source code and looking for faults of a certain type. We have developed a identifies statements in which arrays are accessed out Of static program analysis tool, called C Global Surveyor bounds, or, pointers are used outside the memory region (CGS), which can analyze large C programs for embedded they should address. -
A Study on Connectivity and Accessibility Between Tram Stops and Public Facilities: a Case Study in the Historic Cities of Europe
Urban Street Design & Planning 73 A study on connectivity and accessibility between tram stops and public facilities: a case study in the historic cities of Europe Y. Kitao1 & K. Hirano2 1Kyoto Women’s University, Japan 2Kei Atelier, Yame, Fukuoka, Japan Abstract The purpose of this paper is to understand urban structures in terms of tram networks by using the examples of historic cities in Europe. We have incorporated the concept of interconnectivity and accessibility between public facilities and tram stops to examine how European cities, which have built world class public transportation systems, use the tram network in relationship to their public facilities. We selected western European tram-type cities which have a bus system, but no subway system, and we focused on 24 historic cities with populations from 100,000 to 200,000, which is the optimum size for a large-scale community. In order to analyze the relationship, we mapped the ‘pedestrian accessible area’ from any tram station in the city, and analyzed how many public facilities and pedestrian streets were in this area. As a result, we were able to compare the urban space structures of these cities in terms of the accessibility and connectivity between their tram stops and their public facilities. Thus we could understand the features which determined the relationship between urban space and urban facilities. This enabled us to evaluate which of our target cities was the most pedestrian orientated city. Finally, we were able to define five categories of tram-type cities. These findings have provided us with a means to recognize the urban space structure of a city, which will help us to improve city planning in Japan. -

On Abstraction in Software Verification ‹
On Abstraction in Software Verification ‹ Patrick Cousot1 and Radhia Cousot2 1 École normale supérieure, Département d'informatique, 45 rue d'Ulm, 75230 Paris cedex 05, France [email protected] www.di.ens.fr/~cousot/ 2 CNRS & École polytechnique, Laboratoire d'informatique, 91128 Palaiseau cedex, France [email protected] lix.polytechnique.fr/~rcousot Abstract. We show that the precision of static abstract software check- ing algorithms can be enhanced by taking explicitly into account the ab- stractions that are involved in the design of the program model/abstract semantics. This is illustrated on reachability analysis and abstract test- ing. 1 Introduction Most formal methods for reasoning about programs (such as deductive meth- ods, software model checking, dataflow analysis) do not reason directly on the trace-based operational program semantics but on an approximate model of this semantics. The abstraction involved in building the model of the program seman- tics is usually left implicit and not discussed. The importance of this abstraction appears when it is made explicit for example in order to discuss the soundness and (in)completeness of temporal-logic based verification methods [1, 2]. The purpose of this paper is to discuss the practical importance of this ab- straction when designing static software checking algorithms. This is illustrated on reachability analysis and abstract testing. 2 Transition Systems We follow [3, 4] in formalizing a hardware or software computer system by a transition system xS; t; I; F; Ey with set of states S, transition relation t Ď pS ˆ Sq, initial states I Ď S, erroneous states E Ď S, and final states F Ď S. -

A Holographic Memoirs of a Dream (All the Memoirs Everywhere in the Years of Dreaming This Dissertation)
HOLOGRAPHIC MEMOIRS OF A DREAM – THE INVENTION OF TRAM HOPPING by JOHANNES ANDRIES NORTJÉ submitted in accordance with the requirements for the degree of DOCTOR OF THEOLOGY in the subject SYSTEMATIC THEOLOGY at the UNIVERSITY OF SOUTH AFRICA SUPERVISOR: PROFESSOR E VAN NIEKERK JANUARY 2012 ACKNOWLEDGEMENTS To be true to the thesis of my dissertation, this dissertation is an ubuntuing, a dependent arising, and so it is our dissertation: we have put pen to paper and so credit is due to a whole community. My first acknowledgement goes to the one LORD our one God-s (El-ohim), YAHWEH, Yeshua and Rauch HaKodesh, who has not only inspired this story, but also given the opportunity to tell this story. It has literally been as if this path I/we walked has chosen me/us, and not I/we the path: so many choices and events could have been so different so that the dot pattern drawing could be no co-incidence, especially since many things had been contrary from what I intended. To add to this, all the aha moments I had in the ubuntuings of my meditations, and all the 'out of the blue' 'bright ideas' I accredit to these ubuntuings, and want to assure my LORD I'm not committing plagiarism – it is our/Your dissertation, since the inflation of the cognitive balloon has been with the breath of heaven, so it's in the first place YOUR informationing dissertation. Starting with names is a long list and longer than what I can list. To start with I want to say thank you to my family, Helen, Leandra-Joelle and Enrico, and all the sacrifices they had to make, and particularly Helen that had to work a full-time job while running a household when I was battling with my health (part of my story) and working on this dissertation. -

They make direct connections between town centers and surrounding regions possible, by physically linking existing regional heavy-rail networks with urban tram-networks. The Tram-Train approach offers many advantages by using existing infrastructure to improve regional transit. However using two very different networks and mixing heavy rail and tram operations increases complexity and often requires compromise solutions. The research surveyed existing systems to identify key requirements for successfully introducing Tram-Train systems. These requirements include network design, city layout, population density, and physical factors (e.g., platform heights). One of the most important factors is cooperation between many actors including transit operators, railways and cities. Tram-Train systems are complex, but can provide significant benefits in the right situations. -
