description: A Hilbert space embedding of a distribution---in short, a kernel mean embedding---has recently emerged as a powerful tool for machine learning and inference. The basic idea behind this framework is to map distributions into a reproducing kernel Hilbert space (RKHS) in which the whole arsenal of kernel methods can be extended to probability measures. It can be viewed as a generalization of the original "feature map" common to support vector machines (SVMs) and other kernel methods. While initially closely associated with the latter, it has meanwhile found application in fields ranging from kernel machines and probabilistic modeling to statistical inference, causal discovery, and deep learning. The goal of this survey is to give a comprehensive review of existing work and recent advances in this research area, and to discuss the most challenging issues and open problems that could lead to new research directions. The survey begins with a brief introduction to the RKHS and positive definite kernels which forms the backbone of this survey, followed by a thorough discussion of the Hilbert space embedding of marginal distributions, theoretical guarantees, and a review of its applications. The embedding of distributions enables us to apply RKHS methods to probability measures which prompts a wide range of applications such as kernel two-sample testing, independent testing, and learning on distributional data. Next, we discuss the Hilbert space embedding for conditional distributions, give theoretical insights, and review some applications. The conditional mean embedding enables us to perform sum, product, and Bayes' rules---which are ubiquitous in graphical model, probabilistic inference, and reinforcement learning---in a non-parametric way. We then discuss relationships between this framework and other related areas. Lastly, we give some suggestions on future research directions.

description: Therotationofthecosmicobjectsisauniversalphenomenonanditsoriginisstillanopenquestion.Here a model for the origin of rotation is presented. After an investigation of the phase transition of a scalar field in de Sitter and Gödel backgrounds, the motion of a test particle during the phase transitions is studied. Then using computer simulation for a congruence of particles, we show that although the local induced rotation is nonzero, the global rotation is below the observational limit.

description: In this article, the linear plus modified Yukawa potential (LIMYP) is used as the quark antiquark interaction potential for the approximate analytical bound state solution of the Klein Gordon equation in three-dimensional space. The energy eigenvalues and associated wavefunction are obtained by solving the Klein Gordon equation analytically using the Nikiforov Uvarov (NU) method. The mass spectra of heavy mesons such as charmonium $(c\bar{c})$, bottomonium $(b\bar{b})$, and $b\bar{c}$ for various quantum states are obtained using the energy spectra expression. In comparison to experimental data, graphical modification of acquired mass spectra of heavy mesons with the parameter employed in the energy equation and the current potential provides good results.

Catching up with the Past: A Small Contribution to a Long History of Interactive Environments
Creators: name: Fox, Michael
Publisher: name: FOOTPRINT
Year: 2010

description: This paper documents the evolution of my thinking in the area of interactive architecture over the past 15 years with students and my office. The work is framed within an overview of a long history of work in the area by others. My personal development has taken a number of clear steps in a relatively logical progression. In summary, the work began with kinetics as a means to facilitate adaptation. Work in this area led to integrating computation as a means of controlling the kinetics. The combination of these two areas led to the use of discrete mechanical assemblies as a systems approach to interaction design, which led to the thinking of control as bottom-up and emergent. Consequently I became fascinated with modular autonomous robotics and the notion that actual architectural space could be made of such systems. This in turn led to the exploration of biomimetics in terms of the processes, which eventually led to the idea that the parts in a system should get smaller to the point that they make up the matter itself. The paper concludes with an explanation of how technical advancements in manufacturing, fabrication and computational control will continue to expand the parameters of what is possible in robotics, and consequently influence the scale by which we understand and construct our environments. The future of interactive environments will most certainly involve re-examining the scale by which things operate to the extent that much of the operations happen within the materials themselves. This scaling down is beginning to force a reinterpretation of the mechanical paradigm of adaptation.

description: In order to have a new perspective on the long-standing problem of the mass gap in Yang-Mills theory, we study the quantum Yang-Mills theory in the presence of topologically nontrivial backgrounds in this paper. The topologically stable gauge fields are constrained by the form invariance condition and the topological properties. Obeying these constraints, the known classical solutions to the Yang-Mills equation in the 3- and 4-dimensional Euclidean spaces are recovered, and the other allowed configurations form the nontrivial topological fluctuations at quantum level. Together, they constitute the background configurations, upon which the quantum Yang-Mills theory can be constructed. We demonstrate that the theory mimics the Higgs mechanism in a certain limit and develops a mass gap at semi-classical level on a flat space with finite size or on a sphere.

description: The fifth issue of Footprint investigates the question of metropolitan form. The necessity to focus on the scale of metropolitan areas is manifest as this is the dominant scale of contemporary global life. The process of urbanisation and the size of urban agglomerations have dramatically increased since the last decades. These dynamics alone demand radically changed thinking about internal spatial organisation and the form of urban regions. Yet, scholarly focus at the regional level has shifted away from spatial thinking of overall form towards issues of governance, socio-economic statistics, and global networks. While these approaches provide insight into contemporary conditions, lost in translation is the question of metropolitan form: what are the characteristics of its spatio-physical structures? What are its distinguishable elements? And what are the factors that determine the transformation of form through time? By addressing the question of metropolitan form we try to extrapolate - scale-up - the research notions and methods of ‘urban morphology’ from the ‘urban’ to the ‘regional’ scale.

description: Posing the concept of ‘metropolitan form’ as a question, as in the call for papers for this issue of Footprint, is an absolute necessity at this stage of development of urbanised areas. Many of the papers in this issue begin with the straw-man notion of a formless agglomeration of activities and spaces, the – for lack of a better phrase – postmodern urban experience.[1] There is a persistent theme in the related literatures of architecture, urban design and urban and regional planning that the physical form of the contemporary metropolis is un-describable. Soja’s six metaphors (post-Fordist industrial, cosmopolis, expolis, fractal city, carceral archipelago, simcities) are being indicative of the wide range of possible images.[2] The eight papers in this issue of Footprint take an opposite approach. They begin to trace the contours of the debate around how the noun ‘metropolitan form’ might be understood, how it might be studied, and how it might be possible to move from an empirical understanding of its structure to more intuitive design solutions.

Another Form: From the ‘Informational’ to the ‘Infrastructural’ City
Creators: name: Read, Stephen
Publisher: name: FOOTPRINT
Year: 2009

description: The city is at once material and medium, substantial and enduring on the one hand but mobile, changeable and different things to different people on the other. So to speak of its form has never been straightforward. In the last fifty years the city has become enmeshed in momentous processes transforming our societies and our senses of our place in the world. We have seen urban places become drawn into ever more integrated circuits with other places across the boundaries of nations and continents. This leaves us with question marks about the places we inhabit today and has generated problems of place and coherence in the contemporary city. Without offering solutions to problems of sprawl and fragmentation, I propose here a way of understanding the city and its growth as ordered. To do this I extend Castells’s idea of the ‘technological paradigm’ to spaces of places as well as those of flows and outline an urban form comprising limited technical systems, both high and low tech, establishing coherent and bounded infrastructures of objects, subjects and practices. These infrastructures are internally ordered as total technical systems or paradigms while they are also externally related to other infrastructures in backward and forward articulations that are capable of being generative and place-forming. I argue that we need to understand complex processes of boundary and centre formation in these articulations and use this knowledge to deliver a ‘dappled world’ of varying niches or inhabitable places from the very large to the very small. We need to find alternatives to the macrophysics and smooth pervasive power of the space of flows by maintaining, inventing and reinventing microphysical architectures of enabling places offering us multiple ways of being and living in our contemporary city.

On the other hand, taking the infimum of the lengths of all paths connecting two points in GL^+_n gives an intrinsic metric. We prove bilipschitz equivalence for intrinsic and extrinsic metrics on GL^+_n, exploiting the conical structure of the stratification of the space of n by n matrices by rank.

description: This paper process two robust models for site selection problems for one of the major Hospitals in Hong Kong. Three parameters, namely, level of uncertainty, infeasibility tolerance as well as the level of reliability, are incorporated. Then, 2 kinds of uncertainty; that is, the symmetric and bounded uncertainties have been investigated. Therefore, the issue of scheduling under uncertainty has been considered wherein unknown problem factors could be illustrated via a given probability distribution function. In this regard, Lin, Janak, and Floudas (2004) introduced one of the newly developed strong optimisation protocols. Hence, computers as well as the chemical engineering [1069-1085] has been developed for considering uncertainty illustrated through a given probability distribution. Finally, our accurate optimisation protocol has been on the basis of a min-max framework and in a case of application to the (MILP) problems it produced a precise solution that has immunity to uncertain data.
Changing Perspectives on the Planning of Ankara (1924-2007) and Lessons for a New Master-Planning Approach to Developing Cities
Creators: name: Çalişkan, Olgu
Publisher: name: FOOTPRINT
Year: 2009

description: As one of the newly planned capitals in the 20th century – like Islamabad, Canberra and Brazil –, Ankara represents an original case in planning history: from shaping a new town under the influence of early European urbanism to the control of a dynamic metropolitan form by structural planning approaches. Forming its urban core according to the initial planning perspectives between the beginning of 1930s and the mid-1970s, the city has entered a rapid phase of space production in its extensions for about the last thirty years. In the current period of development, highly fragmented urban peripheral formation has being occurred in Ankara. Since the existing trend on the dispersion of urban form lacking spatial coherence at different scale-levels causes the dominance of the private domain and a loss of urbanity, this trend might at first glance be considered as a break with the European tradition and the emergence of Anglo-Americanization in Turkish planning system in terms of looser development control approach on urban form. Before, coming to such a critical end-point, the paper prefers a closer look into the changing dynamics of master plans of the city. It is aimed to reveal the developmental logic of the city by means of master plan analysis. The comprehensive outlook – called plan matrix – is integrated into each master plan schema by correlating the basic components like main policy directions, depth of control, settlement typology, and city structure and form. Such a framework has a potential to be utilized for any kind of plan analysis at metropolitan scale for different cases. At the end of the analysis, the paper tends to address an alternative master planning approach for the similar types of developing cities striving for keeping its urban character within a fragmented urban body.

Fracture resistance and surface treatment of Y-TZP prepable ceramic abutments and bars
Creators: name: Adatia, Nimet Diamond
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Intraoral preparation of zirconia implant abutments creates deep surface defects making abutments susceptible to fracture during loading. Fracture strengths were tested for (1) HIP-processed zirconia bars (Astra-Tech) after preparation and/or surface repair treatments: no preparation (NP), dry-preparation (DP), wet-preparation (WP), or we-tpreparation and 30d water storage (WP+30d), mitigating treatment of bonding agent (WP+B), sandblasting (WP+SB), or polishing (WP+P), and (2) abutment-assemblies (preparations of 0, 0.5, or 1mm margin reduction). NP established the strength for pristine zirconia bars (1634 plus or minus 95MPa). DP (1144 plus or minus 109MPa), WP (1442 plus or minus 89MPa), WP+30d (1193 plus or minus155MPa), and WP+B (1218 plus or minus 77MPa) groups had significantly (p less than or equal to 0.05) reduced strengths. WP+SB (1632 plus or minus 134MPa) or WP+P (1664 plus or minus 176MPa) repairs equally well recovered original strengths (p<0.001). There were no statistically significant differences (p>0.05) among different abutment-assembly groups and no logical relationship of strength to increasing amount of reduction. All fractures occurred at the interface where the abutment was connected to the analog, suggesting that fracture was unrelated to the actual abutment.
The Landscape Form of the Metropolis

Publisher: name: FOOTPRINT
Year: 2009

description: When the city disintegrates into an archipelago of fragments a new role is imposed on the landscape as a carrier of topographical characterizations, cohesion and continuity. Patterns such as transportation corridors, settlement areas and landscape voids can be regarded as latent macro-landscape forms of the metropolitan territory. In the staging of the metropolis these forms need to be embedded in a compositional structure that addresses fragmentation and disorientation, without relapsing into utopian forms of the traditional city that have proven inadequate for the metropolitan condition. The potential basis to inform this structure is the landscape itself: permanent, neutral and ubiquitous. The underlying landscape also contains an annotated catalogue of situations, in which the genius loci is recorded and secured. These latent compositional elements are transformed into landscape architectural ‘narratives’ within the topography of the emerging metropolis. The enlargement and distortion of specific topographies result in a field of new topologies, drawn from the genius loci and from local cultures and customs. The question is not so much if metropolitan form is determined by landscape, but how we can use it to structure and give meaning to dispersed territories. This involves a delicate choreography of macro-landscape forms and the micro-topography of landscape places.

Not just a women's issue anymore: a narrative profile of a male-outreach sexual-assault prevention program and the men who choose to lead it
Creators: name: Blatt, Rebecca
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Research suggests that one in four college women has survived rape or an attempted rape in her lifetime. This master's thesis examines the roles men play in trying to reduce that statistic. It focuses on the stories of four men who spent this year presenting sexual-assault education programs to college students across the country. It explores the social, historical and political contexts for their work in an effort to understand why men are becoming increasingly involved in rape prevention. Reporting included an extensive literature review, visits to the homes of the four primary subjects, three weeks spent following them to five college campuses and interviews with more than 60 sources. The final product is a long-form narrative in the tradition of literary journalism. It traces the stories of a movement, an organization and four young leaders.

description: Estimates of the real death toll of the COVID-19 pandemic have proven to be prob- lematic in many countries, Italy being no exception. Mortality estimates at the local level are even more uncertain as they require stringent conditions, such as granular- ity and accuracy of the data at hand, which are rarely met. The “official” approach adopted by public institutions to estimate the “excess mortality” during the pan- demic draws on a comparison between observed all-cause mortality data for 2020 and averages of mortality figures in the past years for the same period. In this paper, we apply the recently developed machine learning control method to build a more realistic counterfactual scenario of mortality in the absence of COVID-19. We dem- onstrate that supervised machine learning techniques outperform the official method by substantially improving the prediction accuracy of the local mortality in “ordi- nary” years, especially in small- and medium-sized municipalities. We then apply the best-performing algorithms to derive estimates of local excess mortality for the period between February and September 2020. Such estimates allow us to provide insights about the demographic evolution of the first wave of the pandemic through- out the country. To help improve diagnostic and monitoring efforts, our dataset is freely available to the research community.

We also describe a unique vector field $\textsf{R}$ in $\textsf{T}$ which contracted with the Gauss-Manin connection gives an upper triangular matrix with some non-constant entries which are natural generalizations of Yukawa couplings. For $n=1,2$ we compute explicit expressions of $\textsf{R}$ and give a solution of $\textsf{R}$ in terms of quasi-modular forms. The moduli space $\textsf{T}$ is an affine variety and for $n=4$ we give explicit coordinate system for $\textsf{T}$ and compute the vector field $\textsf{R}$ and the $q$-expnasion of its solution.

description: Unmanned aerial vehicles (UAVs) rely on optical sensors such as cameras and lidar for autonomous operation. However, such optical sensors are error-prone in bad lighting, inclement weather conditions including fog and smoke, and around textureless or transparent surfaces. In this paper, we ask: is it possible to fly UAVs without relying on optical sensors, i.e., can UAVs fly without seeing? We present BatMobility, a lightweight mmWave radar-only perception system for UAVs that eliminates the need for optical sensors. BatMobility enables two core functionalities for UAVs -- radio flow estimation (a novel FMCW radar-based alternative for optical flow based on surface-parallel doppler shift) and radar-based collision avoidance. We build BatMobility using commodity sensors and deploy it as a real-time system on a small off-the-shelf quadcopter running an unmodified flight controller. Our evaluation shows that BatMobility achieves comparable or better performance than commercial-grade optical sensors across a wide range of scenarios.

description: The rise in popularity and ubiquity of Twitter has made sentiment analysis of tweets an important and well-covered area of research. However, the 140 character limit imposed on tweets makes it hard to use standard linguistic methods for sentiment classification. On the other hand, what tweets lack in structure they make up with sheer volume and rich metadata. This metadata includes geolocation, temporal and author information. We hypothesize that sentiment is dependent on all these contextual factors. Different locations, times and authors have different emotional valences. In this paper, we explored this hypothesis by utilizing distant supervision to collect millions of labelled tweets from different locations, times and authors. We used this data to analyse the variation of tweet sentiments across different authors, times and locations. Once we explored and understood the relationship between these variables and sentiment, we used a Bayesian approach to combine these variables with more standard linguistic features such as n-grams to create a Twitter sentiment classifier. This combined classifier outperforms the purely linguistic classifier, showing that integrating the rich contextual information available on Twitter into sentiment classification is a promising direction of research.

description: Sometime in the 1990s architecture historians shifted their attention from buildings to publications, exhibitions, films and photographs produced by architects. This shift is related to the more general transformation in which ‘society’ has been substituted by ‘culture’. More than any other work it is Beatriz Colomina’s Privacy and Publicity that has come to represent this growing interest of architecture historians. The following review article closely studies the arguments and methodologies at the centre of Privacy and Publicity as a means of delineating the idealism that is the subtext of this shift.

description: With the continuous growth of internet users and media content, it is very hard to track down hateful speech in audio and video. Converting video or audio into text does not detect hate speech accurately as human sometimes uses hateful words as humorous or pleasant in sense and also uses different voice tones or show different action in the video. The state-ofthe-art hate speech detection models were mostly developed on a single modality. In this research, a combined approach of multimodal system has been proposed to detect hate speech from video contents by extracting feature images, feature values extracted from the audio, text and used machine learning and Natural language processing.

description: Anhand von gesellschaftspolitischen, demographischen und kulturellen Entwicklungen werden in Anlehnung an Michel Foucault die konstituierenden Regeln eines innerjüdischen Diskurses beschrieben, welcher vor zwei Jahrzehnten in der Bundesrepublik Deutschland und der DDR entstanden ist. Innerhalb dieses Diskurses wird die junge jüdische Gegenwartsliteratur verortet, die durch signifikante Korrespondenzen zur gesellschaftlichen Wirklichkeit gekennzeichnet ist. Mithilfe einer methodenpluralistischen Vorgehensweise, die neben literatur-wissenschaftlichen Ansätzen auch solche der geschichtsphilosophischen, sozio-psychologischen, kunst- und kulturhistorischen Forschung einbezieht, wird die Konstruktion junger jüdischer Identität in ausgewählten Texten exemplarisch untersucht. Wiederkehrende Konstanten der Identitätskonstruktionen werden genauso herausgearbeitet wie Divergenzen der ästhetischen Verfahren, durch die subversive, oftmals geschlechtsspezifisch konnotierte Deutungsebenen eröffnet werden. Dem übergeordneten Interesse der Arbeit folgend, werden die Ergebnisse der Textanalysen innerhalb des diskursiven Aussagekontextes betrachtet.
description: Following Michel Foucault, the author uses socio-political, demographic, and cultural developments to define a set of rules organizing the inner-Jewish discourse that emerged approximately two decades ago in the Federal Republic of Germany and the former GDR. Within that discourse, the author locates a body of contemporary German-Jewish literature characterized by strong resemblances to socio-historical reality. The dissertation examines the construction of contemporary Jewish identity within selected works of literature, using a variety of methodological approaches from the fields of literary criticism, history of art, culture and philosophy as well as socio-psychology. Recurring identity traits within those constructions are emphasized as well as differences in the aesthetic scheme which often bear subversive, gender specific connotations. Consistent with the overall aim of the dissertation, the results of the literary analyses are transferred to the discursive level.
Notes on Post-criticality: Towards an Architecture of Reflexive Modernisation
Creators: name: Cowherd, Robert
Publisher: name: FOOTPRINT
Year: 2009

description: Since around 2002, the performance of critical theory in architecture and the humanities has itself undergone a critical re-evaluation. Authors representing divergent perspectives, from theory’s perennial naysayers to the standard bearers of critical theory themselves, have converged towards a similar conclusion: judged by outcomes, critical theory has proven ineffective at best, and arguably, corrosive to human progress. In architecture, the debate has revolved around the identification of a ‘critical architecture’ in education and production since the 1970s. In apparent rejection of the isolation and purity of critical architecture’s orthodoxy, Rem Koolhaas and others have chosen engagement with the forces (and commissions) of late capitalism to which the term ‘post-criticality’ has been applied. Beyond the confining dichotomies of the post-criticality debate is a perspective offered by sociologists Ulrich Beck, Scott Lash and Anthony Giddens on what they have called a ‘second modernity’ or ‘reflexive modernisation’. This literature re-contextualises the modern-postmodern pairing within the larger trajectory of modernity and identifies a characteristic distinction from former modernities in the term ‘reflexivity’. Where high modernism pursued utopian ideals of pure form and functional simplicity, reflexive modernisation acknowledges contingency in human systems establishing feedback loops that trigger course corrections in the process of modernisation itself. Operating against the ossifications of twentieth-century modernity, reflexivity opens prospects for a second modernisation characterised by a heightened capacity to deal with complexity and time. Speculative architectures of reflexive modernisation benefit from a re-engagement in real-world problems, particularly at the scale of the city. To what extent can considerations of political economy, culture, globalisation, and environmental crisis be translated into the explicit performance criteria and computational parameters? What role is there for tools forged in the fires of ‘critical architecture’ in the emerging architectural creativity increasingly characterised by complexity, provisional outcomes, and unpredictable form?

Theatrical Tectonics: The Mediating Agent for a Contesting Practice
Creators: name: Hartoonian, Gevork
Publisher: name: FOOTPRINT
Year: 2009

description: This paper posits the idea that the theme of agency in architecture is parallactic. It discusses the tectonic as an agent through which architecture turns into a state of constant flux. The intention is to promote a discourse of criticality, the thematic of which is drawn from the symptoms that galvanise architecture’s rapport with the image-laden culture of late capitalism. In an attempt to log the thematic of a contested practice, this essay will re-map the recent history of contemporary architecture. Exploring New Brutalism’s criticism of the established ethos of International Style architecture, the first part of this paper will highlight the movement’s tendency towards replacing the painterly with the sculptural, and this in reference to the contemporary interest in monolithic architecture. Having established the import of tectonics for the architecture of Brutalism, the paper then argues that in the present situation, when architecture – like other cultural products – is infatuated with the spectacle of late capitalism, a re-thinking of the Semperian notion of theatricality is useful. Of interest in the tectonic of theatricality is the work’s capacity to bring forth the division between intellectual and physical labours, and this in reference to architecture’s reserved acceptance of technification for which the aforementioned division is vital. Particular attention will be given to two projects, Zaha Hadid’s Phaeno Center and OMA’s Casa da Musica, where architectonic aspects of New Brutalism are revisited in the light of the tectonic of theatricality.

description: We show that nano-mechanical vibrations in a magnetic shuttle device can be strongly affected by external microwave irradiation through photo-assisted electronic spin-flip transitions. Mechanical consequences of these spin-flips are due to a spin-dependent magnetic force, which may lead to a nano-mechanical instability in the device. We derive a criterion for the instability to actually occur and analyze different regimes of possible nano-mechanical oscillations. Possible experimental realizations of the spin-mediated photo-mechanical instability and detection of the device back action are discussed.

Beyond Discourse: Notes on Spatial Agency
Creators: name: Schneider, Tatjana
name: Till, Jeremy
Publisher: name: FOOTPRINT
Year: 2009

description: This article investigates the word ‘agency’ in relation to the role, responsibility and power of the architect. Using Anthony Giddens’s formulation of agency, we discuss the transformative potential of architecture where the lack of a predetermined future is seen as an opportunity and not a threat. Four episodes describe related instances of architectural practice as spatial agency: muf, OSA, Santiago Cirugeda and The New Architecture Movement. The paper concludes with an urgent call for architects to face up to their political and environmental responsibilities.

Before and After AGENCY
Creators: name: Research Group, The Agency
Publisher: name: FOOTPRINT
Year: 2009

description: This article offers a critical review of the conference AGENCY (November 2008), written by ‘The Agency’, a research group based in the School of Architecture at the University of Sheffield, where the conference was held. It was hoped that the submissions to the conference would energise the relationships between the humanities, the architectural profession, and society. The article sets out some of the questions that were explicitly posed, or that were implicit within, or anticipated in response to these relationships. The broad themes of discourse regarding agency from the conference are summarised in the context both of these questions, and of other themes that emerged from the papers presented: urban agencies, pedagogical agencies, social and technological agencies, sustainability, ecology, ethical, and aesthetic agencies. Alongside this strand of academic presentation and reflection, the article also discusses the conference itself as an event through and within which agency was encouraged. It raises the profile of numerous ‘fringe events’, including seminars and workshops, exhibitions, book launches and social gatherings, that were explicitly organised to extend the potential involvement of other audiences, and the dynamics of other discourses. The differences between this approach and conventional academic conferences are considered, particularly the extent to which each can involve and inform practice in the studio, and the benefits and drawbacks reflected upon. All of these influence the potential agency of architecture practitioners, educators and researchers, and will inform the future activities of ‘The Agency’ group.

Whatever Happened to Projective Architecture? Rethinking the Expertise of the Architect
Creators: name: Schrijver, Lara
Publisher: name: FOOTPRINT
Year: 2009

description: This review article takes the discussion of ‘projective’ architecture as its starting point, and proposes that this recent debate may still be worthwhile to rethink the relationship between practice and theory in architecture. The spirit of ‘projective’ architecture suggests that we rethink how architecture ‘works’. This would entail understanding the reconfigured relation between political/societal and aesthetic/cultural engagement. Drawing from the ideas in the American debate on the ‘projective’ and the recent work of Richard Sennett on ‘craft’, this article puts forward the position that the notion of the ‘projective’ can extend the insights of critical theory towards a more fruitful dialogue with the everyday practice of architecture.

Broadband and Resonant Approaches to Axion Dark Matter Detection

description: When ultralight axion dark matter encounters a static magnetic field, it sources an effective electric current that follows the magnetic field lines and oscillates at the axion Compton frequency. We propose a new experiment to detect this axion effective current. In the presence of axion dark matter, a large toroidal magnet will act like an oscillating current ring, whose induced magnetic flux can be measured by an external pickup loop inductively coupled to a SQUID magnetometer. We consider both resonant and broadband readout circuits and show that a broadband approach has advantages at small axion masses. We estimate the reach of this design, taking into account the irreducible sources of noise, and demonstrate potential sensitivity to axion-like dark matter with masses in the range of 10^{-14}-10^{-6} eV. In particular, both the broadband and resonant strategies can probe the QCD axion with a GUT-scale decay constant.

On Tate Modern’s Turbine Hall and 'The Unilever Series'
Creators: name: Davidts, Wouter
Publisher: name: FOOTPRINT
Year: 2007

description: Since the opening Tate Modern in 2000, the vast space of the Turbine Hall has hosted The Unilever Series. Widely acclaimed artists Louise Bourgeois, Juan Munõz, Anish Kapoor, Olafur Eliasson, Bruce Nauman, Rachel Whiteread, Carsten Höller and most lately Doris Salcedo accepted the invitation to ‘tackle’ what is arguably the biggest museum space in the world and realized what is invariably held to be their ‘biggest work ever.’ The Unilever Series is not the only large-scale installation series. In recent years, we witnessed the worldwide launch of ever-larger art commissions for increasingly vaster spaces, resulting in all the more colossal artworks. Only recently, Paris announced its own yearly art commission for the central nave of the Grand Palais, suitably entitled Monumenta. The essay examines The Unilever Series in Tate Modern’s Turbine Hall, and discuss it within the global leap in scale and massive expansion of the art and museum world, of which the London institution and its vestibule in particular are the most blatant exponents. While it is certainly true that the spectacular expansion of art installations has occurred in tandem with a profusion of large international exhibitions and ‘destination’ museum of inordinately vast proportions, the assumption that large exhibition spaces demand an art of size is too simplistic. By examining the institutional, spatial and material disposition of the Turbine Hall, I will demonstrate that it is far more than a plain and abstract emblem of the global inflation and growth of museum and exhibition spaces. It’s a distinct architectural exponent of this tendency that essentially in and of itself has informed the inflation of the artworks that have been commissioned for it.

BB mode angular power spectrum of CMB from massive gravity

description: The BB-mode correlation angular power spectrum of CMB is studied for primordial massive gravitational waves for several inflation models. The comparative study of the angular power spectrum with the joint BICEP2/Keck Array and Planck data suggests further constraint on the lower and upper bounds on the mass of primordial gravitons. Assuming a modified dispersion relation, the mass of primordial graviton is also calculated. The resulting constraint also agrees with other theoretical estimates.

Post-fidelity: a new age of technological innovation and music consumption
Creators: name: Guberman, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Since the popularization of the iPod, the ideal recorded music consumption experience for most consumers has become one of quantity, variety, ease of use, and visual style. I focus on the contrast between these values and the emphasis on fidelity that dominated discussions of sound reproduction throughout the 20th century. I first demonstrate the extent to which fidelity dominated innovation and marketing during the 20th century, showing that even new devices which did not improve fidelity were advertised to give the impression that they did. I then examine the iPod as a breakthrough product, which changed the format of music and how we define the ideal listening experience in this post-fidelity era. Finally, I contextualize the importance of this trend in consumer culture: using print and internet sources to argue that even audiophiles have begun to value these other qualities as much or more than sound quality.
