Fail-Safe Testing of Safety-Critical Systems
… proposes an approach for testing of safety-critical systems. It is based on a behavioral and a fault model. The two models are analyzed for compatibility and necessary changes are identified to make them compatible. Then transformation rules are used to transform the fault model into the …

The architecture and acuity of critical systems thinking
This thesis looks at two critical urges in Critical Systems Thinking that both complement and critique each other. Firstly, there is an urge to construct in a critical manner. Secondly, there is an urge to be critical about such constructions. They complement and critique each other in the manner …

Fail-Safe Test Generation of Safety Critical Systems
… for testing proper failure mitigation in safety critical systems. Unlike other approaches which integrate behavioral and failure models, and then generate tests from the integrated model, we build safety mitigation tests from an existing behavioral test suite, using an explicit mitigation model …

Critical systems thinking and pluralism : a new constellation
… and the solutions offered by various critical systems writers. The problems of "imperialism" are outlined together with an analysis of the meta-theoretical views which purport to avoid imperialism. It is suggested that researchers attempting to understand alien or incommensurable …

Verification of advanced controllers for safety-critical systems
… high running time when applied to more complex systems with more parameters. This, in some cases, limits the complexity of the system that we could consider. Therefore, we focused our attention on control problems such as obtaining an explicit MPC law for a linear time invariant system with a …

Scaling limit of critical systems in random geometry
… several fundamental objects arising from critical physical models. In particular, we consider Schramm--Loewner evolutions, the Gaussian free field, Liouville quantum gravity and the Brownian continuum random tree. We begin by considering branching diffusions in a bounded domain $D\subset$ …

Creative management of creative management : a critical systems approach
This thesis draws on current research from the systems world - that of Critical Systems Thinking - in such a way as to bring the study of creativity into a new era. Recognising a novel link between these two major fields of activity has enabled a new form of creativity to be both developed and …

Next-generation safety-critical systems on multi-core platforms
… running in parallel. As a result, certifying systems deployed using multi-core platforms is significantly more challenging compared to single-core implementations. In this work, we tackle the challenge of restoring the constant WCET assumption for real-time tasks deployed on multi-core …

Modeling and Predicting Incidence: Critical Systems Failures and Flu Infection Cases
Given several related critical infrastructure (CI) networks, such as power grid, transportation, and water systems, one crucial question emerges: how to model the propagation of failed facilities and predict their spread over time to the whole system? Given digital surveillance data, can we predict …

Critical systems thinking, dialogue and quality management in the National Health Service
… Health Service (NHS), the theories of dialogue, critical systems thinking, and quality - and how these domains can be related together to produce a new concept of quality called critical quality.A quality gap is identified between what the NHS produces and what the public requires of it. It is …

Freight Distribution During Disasters: Measuring and Improving Operational Performance of Critical Systems
… the capacity of the freight distribution systems. Accordingly, public and private-sector stakeholders seek disaster preparedness and response interventions to ensure timely and economic distribution of vital freight to the population in need. The goal of this thesis is to facilitate better …

The scaling behavior of the entanglement entropy in 2+1 dimensional critical systems
The entanglement entropy in 1+1 dimensional critical system has been well studied and known to have a universal scaling form that gives information about the underlying critical system. While the case for 1+1 dimensional critical systems has been well studied, the situation in higher dimensional …

A Critical Systems Case Study in Agricultural Technology Development at the Land-Grant University
… Innovation in Agriculture (CAIA). Guided by critical systems heuristics, this case study utilizes five data collection methods to inform a critical case study including: key informant interviews, a document review, a survey, stakeholder interviews, and a focus group. While striving to be a …

Dynamic safety assessment of FPGA-based safety critical systems with applications in nuclear power generation
… (IAEA) states that FPGA implementations of I&C systems in Nuclear Power Plants (NPPs) is expected to increase significantly in the future. One issue facing FPGAs in the nuclear field is a lack of technical standards and design/review documentation. Therefore, the research program undertaken …

A critical systems thinking approach for the planning of information technology in the information society
… Planning (ICTP) from the perspective of Critical Systems Thinking (CST). Nowadays with the increasing use of information and communications technologies and the possibilities of management of information, organisations and people in general focus attention on the planning of these …

Total quality management strategies for small and medium industries in Malaysia : a critical systems approach
A great amount of effort has been given to the development of Malaysian Small and Medium Industries (SMIs) in the last 25 years. 13 Ministries and more than 30 agencies have been involved in these efforts. A large amount of money and other resources were also allocated for their development. These …

Next-generation safety-critical systems using COTS based homogeneous multi-core processors and heterogeneous MPSoCS
… memory for multicore processors suits well for systems where the average-case performance of the system is the performance metric. However, this is not suitable for safety-critical systems where the developer is interested in the worst-case execution time (WCET) of the task on each processing …

Critical systems thinking, theory and practice : a case study of an intervention in two British local authorities
This thesis reports an intervention informed by critical systems thinking. The intervention drew upon a variety of systems and operational research methods to systemically explore the problems facing housing services for older people. Stakeholders were then supported in developing a response to …
