title STAR methodology-based learning about construction accidents and their prevention
source Automation in Construction 4 (1) (1995) pp. 75-85
summary This paper presents the results of a feasibility study concerning the application of STAR-methodology-basedmachine learning to construction accidents and their prevention. A ten-stage knowledge acquisition process is presented and its individual stages described. Knowledge about construction accidents was acquired using a collection of 225 examples, based on actual accidents records. Inductive learning with a system based on the STAR-methodology was employed. This system was used in both the generalization and specialization modes of operation. The decision rules obtained are complex, but their interpretation is clear and they seem to be consistent with the present understanding of causal relationships between accident results and various factors affecting them. Also, the rules were verified using average overall and omission empirical error rates, which were calculated as average for three randomly determined sequences of examples. These error rates were calculated for all seven steps in the machine learning process, and were used to construct learning curves for both error rates. The relationships between error rates and the number of examples used for learning are analyzed, and coefficients of linear regression given and discussed. The 225 examples used were found to be grossly insufficient to produce reliable knowledge about accidents and therefore a large study is postulated which would involve the collection of a larger number of construction accident records. In general, our study demonstrated the feasibility of machine learning in acquiring knowledge about construction accidents.

title Systems Thinking, Systems Practice
source John Wiley & Sons, Chichester
summary Whether by design, accident or merely synchronicity, Checkland appears to have developed a habit of writing seminal publications near the start of each decade which establish the basis and framework for systems methodology research for that decade."" Hamish Rennie, Journal of the Operational Research Society, 1992 Thirty years ago Peter Checkland set out to test whether the Systems Engineering (SE) approach, highly successful in technical problems, could be used by managers coping with the unfolding complexities of organizational life. The straightforward transfer of SE to the broader situations of management was not possible, but by insisting on a combination of systems thinking strongly linked to real-world practice Checkland and his collaborators developed an alternative approach - Soft Systems Methodology (SSM) - which enables managers of all kinds and at any level to deal with the subtleties and confusions of the situations they face. This work established the now accepted distinction between hard systems thinking, in which parts of the world are taken to be systems which can be engineered, and soft systems thinking in which the focus is on making sure the process of inquiry into real-world complexity is itself a system for learning. Systems Thinking, Systems Practice (1981) and Soft Systems Methodology in Action (1990) together with an earlier paper Towards a Systems-based Methodology for Real-World Problem Solving (1972) have long been recognized as classics in the field. Now Peter Checkland has looked back over the three decades of SSM development, brought the account of it up to date, and reflected on the whole evolutionary process which has produced a mature SSM. SSM: A 30-Year Retrospective, here included with Systems Thinking, Systems Practice closes a chapter on what is undoubtedly the most significant single research programme on the use of systems ideas in problem solving. Now retired from full-time university work, Peter Checkland continues his research as a Leverhulme Emeritus Fellow. "

title The Use of Rule-Based Knowledge Discovery Techniques to Profile Black Spots
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary In Belgium, traffic safety is currently one of the highest topics on the list of priorities of the government. The identification of black spots and black zones and profiling them in terms of accident related data and location characteristics must provide new insights into the complexity and causes of road accidents which, in turn, provide valuable input for government actions. Data mining is the extraction of information from large amounts of data. The use of data mining algorithms is therefore particularly useful in the context of large datasets on road accidents. In this paper, association rules are used to identify accident circumstances that frequently occur together. The strength of this descriptive approach lies within the definition of different accident types and the identification of relevantvariables that make a strong contribution towards a better understanding of accident circumstances. An analysis of the produced set of rules, describing underlying patterns in the data, indicates that fiveaspects of traffic accidents can be discerned: collision with a pedestrian, collision in parallel, sideways collision, week/weekend accidents and weather conditions. For each of these accident types, different variables play an important role in the occurrence of the accidents.

title Race track modeler. Developing an Iterative Design Workflow Combining a Game Engine and Parametric Design
source Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary This paper documents the continuing development and testing of a novel digital work flow established and implemented for the design and redevelopment of formula one racing tracks. The Race Track Modeler (RTM) tool uses a game engine to simulate driving around proposed track designs. Performance data from the simulation is combined with real data acquired from analysis of vehicle mounted accident data recorders (ADRs). The output of the tool is a graphical representation of simulated stopping positions of vehicles that have lost control and left the track. This information directly informs the design of motor racing facilities; the zoning of spectator facilities, position and specification of crash barriers (if required), and surface material selection for the run-off zones (the area where vehicles are expected to stop after losing control and leaving the track). The RTM can suggest further design changes to the track geometry which are then fed back into the game engine. The project involves methods of binding analysis of design directly to geometry together with input from interactive controls. The RTM has been developed and tested during the redevelopment of Silverstone race track in the United Kingdom (figure 1) this paper documents the current state of the tool and concludes with proposed future developments.

title Improving Child Safety in Residential Buildings via Architectural Design and Technology Integration
source Vienna University of Technology; Building Science & Technology
summary This work intends to create design guidelines based on the classification of design elements in residential buildings according to risk levels. It suggests the inclusion of safety aspects in children’s immediate environment by better design solutions and technologies which can help to prevent home accidents that mainly affect children aged between 0 and 4 years. The guidelines could help to create new building and design standards for architects and the building industry. They are based on research, conducted mainly in the European Union and the United States of America, into regulations and programs focusing on the prevention of home accidents. This work may be of benefit to parents, manufacturers, the building industry, architects and governments. Parents may benefit, obviously, because they get information on how to decrease the number of hazards within their children’s environment. It may help manufacturers improve their safety standards. Consumers may choose from a range of safer products. It may prompt the building industry to create safer designs and products thus avoiding liability claims. It may inspire architects to a more safety-oriented design. Finally governments could reduce health costs – in Austria alone, for example, more than € 3.4 billion a year are spent on home and leisure accidents.

title Arte Programmata: entre o Acidente e a Programação [Art Programmata: Between the Accident and Programming]
source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary The aim of this paper is the discussion of aspects like accident and programming in the creative process in Media Art As a transdisciplinary and collaborative activity, it could be seen as a possibility for knowledge construction and sharing spaces. It also shows how media art practice can be used as a reference for the creative process in the architectural field. Building knowledge spaces through creative processes is a challenge based on the latest reconfiguration of the relations among artists, artworks and observers, which were enhanced after digital technology. Designing knowledge space as collaborative process, we assume that our examination contribute to any field by stimulating the transitions from analog to digital culture.
