An Introduction to Design Commons
No full textThe reasons for a dedicated edition on “design and commoning” are twofold. First, the recent surge of renewed interest in the social conditions of design remains atheoretical. A deeper theoretical and philosophical foundation will help problematize the link between commoning and design, and in doing so define the operative theories, concepts and frameworks that influence design thinking across a series of design contexts and conditions. And secondly, design has become more ubiquitous, expanding both its domain of influence and conditions of praxis. With this expansion, design touches a variety of contested areas. Designers are continuously challenged by conflicts and edge conditions, having to mitigate between both scales of conflict and the vested interests of individuals. In the global climate of population increase and the prevalent reduction of financial resources the question and theorization of shared capacities will remain part and parcel of future of design thinking. The four thematic clusters contained here exploit the theoretical and philosophical themes related to the large commoning “problematique,” providing designers better grounding in the networked context of the twenty-first century. The explicit theorization of design and the commons will explore the implicit relations through each of the collected contributions to show how this philosophical construct can be explicated in the context of network collectives and transdisciplinary approaches that currently inform design practices.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.Theory, Territories & Transition
Pings and Hups
No full textEtymologically unattested yet artistically long praised, there is a profound relation between life and light; next to both, the almost self-evident (and scientifically undisputed) relation between light and flow, lux and flux. Would it be correct then to understand life as an issue of perception and manipulation of flows? Surprisingly, this is a question that can only be answered by addressing death. As any lensmaker would claim (and philosophy has always had an affinity with this profession), perception is not a synthesis but an ascesis: it does not connect, it disconnects; or, better said, in order to connect, it needs to disconnect. However, following the radical empiricist dictum, one should never speak of perception alone; ever since William James, perception equals action. In other words, perception is not something that happens to us, it is something we do.5 Strange as it may seem therefore, to live one needs to practice death. This book will examine how styling life means styling death and how architecture (in the broadest possible sense) is involved in this continuous process of stylisation. To do so, architecture and perception, duration and individuation, will all converge in practising how one can die without dying in order to enunciate a life.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.Theory, Territories & Transition

Memory Systems and Interconnects for Scale-Out Servers
No full textThe information revolution of the last decade has been fueled by the digitization of almost all human activities through a wide range of Internet services. The backbone of this information age are scale-out datacenters that need to collect, store, and process massive amounts of data. These datacenters distribute vast datasets across a large number of servers, typically into memory-resident shards so as to maintain strict quality-of-service guarantees. While data is driving the skyrocketing demands for scale-out servers, processor and memory manufacturers have reached fundamental efficiency limits, no longer able to increase server energy efficiency at a sufficient pace. As a result, energy has emerged as the main obstacle to the scalability of information technology (IT) with huge economic implications. Delivering sustainable IT calls for a paradigm shift in computer system design. As memory has taken a central role in IT infrastructure, memory-centric architectures are required to fully utilize the IT's costly memory investment. In response, processor architects are resorting to manycore architectures to leverage the abundant request-level parallelism found in data-centric applications. Manycore processors fully utilize available memory resources, thereby increasing IT efficiency by almost an order of magnitude. Because manycore server chips execute a large number of concurrent requests, they exhibit high incidence of accesses to the last-level-cache for fetching instructions (due to large instruction footprints), and off-chip memory (due to lack of temporal reuse in on-chip caches) for accessing dataset objects. As a result, on-chip interconnects and the memory system are emerging as major performance and energy-efficiency bottlenecks in servers. This thesis seeks to architect on-chip interconnects and memory systems that are tuned for the requirements of memory-centric scale-out servers. By studying a wide range of data-centric applications, we uncover application phenomena common in data-centric applications, and examine their implications on on-chip network and off-chip memory traffic. Finally, we propose specialized on-chip interconnects and memory systems that leverage common traffic characteristics, thereby improving server throughput and energy efficiency.PARS
Parenté et société dans le monde grec
No full textLes structures de parenté sont dans l’histoire et, comme telles, elles ne cessent de se transformer, mais elles le font à un rythme et selon des modalités qui diffèrent de ce que l’on observe pour la vie politique, économique ou religieuse. Avec une histoire que, depuis Homère, on peut suivre sur près de trois millénaires, la Grèce offre à cet égard un champ d’observation d’une profondeur exceptionnelle. Le but de cette recherche est de cerner à la fois la continuité et les modifications d’un système de parenté. Cette « étude de terrain » est aussi l’occasion d’approfondir la réflexion sur la notion de parenté. Anthropologues et historiens des diverses périodes de l’histoire de la Grèce, depuis l’archaïsme jusqu’à l’époque contemporaine, se sont retrouvés autour de ce thème lors d’un colloque réuni à Volos du 18 au 21 Juin 2003.

Topics in minimax shrinkage estimation
No full textThe dissertation considers three different topics which pertain to minimax shrinkage estimation:
1) Minimax estimation of a mean vector with variable selection for classes of spherically symmetric distributions: The results of Zhou and Hwang [31] and Maruyama [22] are extended from the normal case with known scale, to scale mixtures of normals and more generally to spherically symmetric distributions with a residual vector. Slight extensions to the class of estimators to which the results pertain are also given.
2) Minimax shrinkage estimators of a location vector under concave loss: In particular it is shown for a wide class of concave loss functions, James-Stein and Baranchik-type estimators which dominate the usual" estimator for quadratic loss also dominate for these concave losses. The distributions studied include multivariate normal distributions with covariance equal to a known multiple of the identity, normal distributions with an unknown scale times the identity, and general scale mixtures of multivariate normal distributions with an unknown scale.
3) Combining unbiased and possibly biased correlated estimators of a mean vector under general quadratic loss: The general approach is to use a shrinkage-type estimator which shrinks an unbiased estimator toward a biased estimator. Conditions under which the combined estimator dominates the original unbiased estimator are given. Models studied include normal models with a known covariance structure, scale mixtures of normals, and more generally elliptically symmetric models with a known covariance structure. Elliptically symmetric models with a covariance structure known up to a multiple are also considered.Ph.D.Includes bibliographical referencesby Stavros Zinono
A Diagrammatic Cartography of Discourses on Architectures of Life and/or Death
No full textThe built environment exerts an essential effect on life. Over the past decades, it has been greatly reconceptualised through various posthuman, ecosystemic, new materialist, material-discursive approaches, which explored the socio-spatial, technological, cognitive, relational, and affective relations that material arrangements, such as architectural ones, shape. As technē, architecture is intricately intertwined not only with processes of easing and facilitating (human) life, but also the management of dynamic processes involving both living and non-living matters. In view of the latter, architecture is ‘life by means other than life’ (Stiegler), shaping living matters by means of non-living matters. The chapter respectively surveys several streams of recent theoretical discourse that developed from Deleuze and Guattari’s as well as Foucault’s thoroughgoing reframing of the agency of matter on life-constituting processes. In the aim of reconsidering and repositioning architecture as a posthuman technique of existence, this cartography charts – with the help of a central navigational diagram – these co-evolving discursive streams in their differing topical-conceptual starting points, and their various converging and bifurcating lines of thinking, in the aim to elaborate on the novel conceptions they have helped distil in the pursuit of a fuller understanding of those material-discursive practices within the relational ecologies of architecture.Accepted Author ManuscriptSituated Architectur
Urban Sustainability at Risk Due to Soil Pollution by Heavy Metals—Case Study: Volos, Greece
No full textThe focus of this case study is the meticulous observation of urban soil pollution by heavy metals (HMs), or, alternatively, potentially toxic elements (PTEs). The study took place in the urban center of Volos, Greece. Moreover, 248 soil samples were collected during 2018–2021 (62 samples annually), while 3.65 km2 was, approximately, the study area. The breakdown of total concentrations took place for the interpretation of different soil parameters, also according to mean values and medians of the total concentrations of HMs, the following decreasing order was monitored: Mn > Zn > Cr > Ni > Cu > Pb > Co > Cd. During the 4-year study, an increasing trend of metal concentration was observed (for each year compared to the previous one). Furthermore, the imaginary triangle, which was observed, is bordered by the historic train station, the two city bus and intercity coach stations and the commercial harbor. Statistical analysis was implemented in order to interpret the exceedances of HMs concerning the Directive 86/278/EEC. Principal component analysis (PCA) is an additional technique that was conducted because of the correlations and interdependences between the HMs. A strong correlation was observed between the HMs, but mainly between Cd and Zn, which is probably due to their common origin. During the COVID-19 pandemic, significant changes in metal concentrations were observed in different parts of the city, due to the limited movement of motorized wheeled vehicles, but also due to the long operating hours of the heating systems in the residential area. Further research is needed in the future in order to identify the sources of pollution and to find possible ways to reduce it. All in all, urban soil pollution by HMs is a great conundrum of the environmental aspect of sustainability
