REVIEW OF D. H. Mellor, 'The Matter of Chance'
No full textThough almost forty years have elapsed since its first publication, it is a testament to the philosophical acumen of its author that 'The Matter of Chance' contains much that is of continued interest to the philosopher of science. Mellor advances a sophisticated propensity theory of chance, arguing that this theory makes better sense than its rivals (in particular subjectivist, frequentist, logical and classical theories) of ‘what professional usage shows to be thought true of chance’ (p. xi)–in particular ‘that chance is objective, empirical and not relational, and that it applies to the single case’ (ibid.). The book is short and dense, with the serious philosophical content delivered thick and fast. There is little by way of road-mapping or summarising to assist the reader: the introduction is hardly expansive and the concluding paragraph positively perfunctory. The result is that the book is often difficult going, and the reader is made to work hard to ensure correct understanding of the views expressed. On the other hand, the author’s avoidance of unnecessary use of formalism and jargon ensures that the book is still reasonably accessible. In the following, I shall first summarise the key features of Mellor’s propensity theory, and then offer a few critical remarks
Control and Chance in Music and Art a Survey of Philosophies
No full textThis article is a survey and review of several writings on the philosophies and compositional techniques involving control and chance in the creation of modern art and music. The purpose of discussing and comparing these writings is to trace different understandings, reactions, and interpretations of these philosophies in order to offer a more informed perspective on these oft misunderstood techniques. The first article analyzed is Robert Charles Clark’s “Total Control and Chance in Musics: A Philosophical Analysis,” which discusses fundamental issues regarding both total control and chance music. The second article, Stephanie Ross’ “Chance, Constraint, and Creativity: The Awfulness of Modern Music,” presents some of the adverse reactions to these methods of composition. The third and fourth articles, Roland Barthes’ “The Death of the Author” and “From Work to Text,” offer a broader philosophical viewpoint on the different roles of the author and their product when creating art. The final article, Jeongwon Joe and S. Hoon Song’s “Roland Barthes’ ‘Text’ and Aleatoric Music: Is the ‘Birth of the Reader’ the Birth of the Listener?” concludes this survey by tying Barthes’ concepts back to music

Distributed chance-constrained model predictive control for condition-based maintenance planning for railway infrastructures
No full textWe develop a Model Predictive Control (MPC) approach for condition-based maintenance planning under uncertainty for railway infrastructure systems composed of multiple components. Piecewise-affine models with uncertain parameters are used to capture both the nonlinearity and uncertainties in the deterioration process. To keep a balance between robustness and optimality, we formulate the MPC optimization problem as a chance-constrained problem, which ensures that the constraints, e.g., bounds on the degradation level, are satisfied with a given probabilistic guarantee. Two distributed algorithms, one based on Dantzig-Wolfe decomposition and the other derived from a constraint-tightening technique, are proposed to improve the scalability of the MPC approach. Computational experiments show that the distributed method based on Dantzig-Wolfe decomposition performs the best in terms of computational time and convergence to global optimality. By comparing the chance-constrained MPC approaches with deterministic approach, and traditional time-based maintenance approach, we show that despite their high computational requirements, chance-constrained MPC approaches are cost-efficient and robust in the presence of uncertainties.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Bart De SchutterRailway EngineeringDelft Center for Systems and Contro

RE:PRINT edited by Véronique Chance and Duncan Ganley, brings together the work of twenty contemporary artists working in the field of expanded printmaking, to explore the relationship between print media, interdisciplinary art and new technologies. A hybrid of art object, book, physical and electronic form, RE:PRINT addresses concerns of reproducibility, technical developments and inter-medial approaches in contemporary art. Through an interplay of image and text from a diverse range of practitioners, RE:PRINT critically rethinks the notion of ‘print’ as both artwork and published multiple and debates what is print in the twenty first century. RE:PRINT includes work by: Jo Stockham, Jo Love, Steve Lovett, Rob Smith, Asim, Véronique Chance, Susana Gómez Larrañaga, Kelcy Davenport, Nerma Cridge, Fay Hoolahan, Richard Kearns, Annis Fitzhugh, James Hutchinson, Monique Jansen, Duncan Ganley, Mark Shaw, Nick Devison, Mark Graver, Meg Rahaim and Emily Godden.

Moving Forward: Expanding the Digital Marketing and Information Technology Strategy of a Thriving Nonprofit
No full textThe purpose of the project was to expand the digital marketing efforts and volunteer reporting and training processes of a thriving nonprofit healthcare organization. In 2015, the organization had an aging Web presence, disparate marketing systems, and inconvenient volunteer reporting and training processes. The project consisted of four central goals: improve website content management and update processes, improve website usability and digital marketing efforts, improve volunteer documentation and reporting processes, and improve volunteer training processes through accessible education resources.
Utilizing a modest budget, the project team sought to improve marketing and information technology processes within the organization by implementing modern technology solutions, integrating systems, and providing convenient resources to stakeholders. The project resulted in a responsive website design, a reduction in ongoing website expenses, online event management and self-service ticketing for fundraising events, an email marketing and social media advertising strategy, HIPAA compliant volunteer reporting processes, and an online volunteer training program
Constraining chance: Chance as a creative catalyst in architectural design
No full textFull text is available to authenticated members of The University of Auckland only.The OuLiPo or ‘Workshop for Potential Literature’ were an avant garde coalition of authors, mathematicians and poets who sought ‘complete control’ of the writing process via the use of writing constraints allowing them to stretch convention, create new forms of literature and veil the author from preconception. Many of their works utilised the generative potential of chance through the use of aleatory yet systematic structures and exercises.This thesis proposes the utilisation of this form of ‘controlled chance’ as a way to invigorate the design process, catalyse creativity and break the habits of the designer. By looking closely at the OuLiPo author, Georges Perec, and his 1978 novel “Life a User’s Manual” this thesis transposes some of his constraints from literature into the discipline of architecture and employs them in the design of an apartment building in downtown Auckland
Chance-Constrained Ancillary Service Specification for Heterogeneous Storage Devices
No full textWe present a method to find the maximum magnitude of any supply-shortfall service that an aggregator of energy storage devices is able to sell to a grid operator. This is first demonstrated in deterministic settings, then applied to scenarios in which device availabilities are stochastic. In this case we implement chance constraints on the inability to deliver as promised. We show a significant computational improvement in using our method in place of straightforward scenario simulation. As an extension, we present an approximation to this method which allows the determined fleet capability to be applied to any chosen service, rather than having to re-solve the chance-constrained optimisation each time.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Intelligent Electrical Power Grid
Chance in the Modern Synthesis
No full textThe modern synthesis in evolutionary biology is taken to be that period in which a consensus developed among biologists about the major causes of evolution, a consensus that informed research in evolutionary biology for at least a half century. As such, it is a particularly fruitful period to consider when reflecting on the meaning and role of chance in evolutionary explanation. Biologists of this period make reference to “chance” and loose cognates of “chance,” such as: “random,” “contingent,” “accidental,” “haphazard,” or “stochastic.” Of course, what an author might mean by “chance” in any specific context varies.
In the following, we first off er a historiographical note on the synthesis.
Second, we introduce five ways in which synthesis authors spoke about
