description: Here we present a model for a small system combined with an explicit entropy bath that is comparably small. The dynamics of the model is defined by a simple matrix, M. Each row of M corresponds to a macrostate of the system, e.g. net alignment, while the elements in the row represent microstates. The constant number of elements in each row ensures constant entropy, which allows reversible fluctuations, similar to information theory where a constant number of bits allows reversible computations. Many elements in M come from the microstates of the system, but many others come from the bath. Bypassing the bath states yields fluctuations that exhibit standard white noise; whereas with bath states the power spectral density varies as S(f)~1/f over a wide range of frequencies, f. Thus, the explicit entropy bath is the mechanism of 1/f noise in this model. Both forms of the model match Crooks' fluctuation theorem exactly, indicating that the theorem applies not only to infinite reservoirs, but also to finite-sized baths. The model is used to analyze measurements of 1/f-like noise from a sub-micron tunnel junction.

description: Sei V ein holomorphes Vektorbündel über einer q-konvexen Mannigfaltigkeit X. Die Andreotti-Grauert-Theorie sagt, dass die r-te Kohomologiegruppe holomorpher Schnitte mit Werten in V endlich-dimensional ist und dass die Kohomologie verschwindet, falls X q-vollständig ist. Ist E ein holomorphes Banachbündel über X, dann ist bekannt, dass die erste Kohomologiegruppe verschwindet, falls X Steinsch ist. Kapitel I gibt einen ausführlichen Überblick über die Arbeit. In Kapitel II wird gezeigt, dass es holomorphe Hilbertbündel über 1-konvexen Mannigfaltigkeiten gibt, für die die erste Kohomologie nicht Hausdorffsch ist. In Kapitel III wird folgender Endlichkeitssatz gezeigt: Ist E ein holomorph triviales Banachbündel oder ein holomorphes Banachbündel von kompaktem Typ mit kompakter Approximationseigenschaft über einer q-konvexen Mannigfaltigkeit X, und ist V ein holomorphes Vektorbündel über X, für das die q-te Kohomologie verschwindet, dann gilt: Die q-te Kohomologie für das Tensorprodukt von V und E ist endlich-dimensional. Ist X q-vollständig, dann verschwindet die r-te Kohomologie, falls r größer oder gleich q ist. Für r größer q kann dies auch für beliebige holomorphe Banachbündel E gezeigt werden. Im Anhang wird skizziert, wie der Ansatz der L2-Methode im Fall r gleich q für Hilbertbündel zu einem Verschwindungssatz führen könnte.
description: Let V be a holomorphic vector bundle over a q-convex manifold X. The Andreotti-Grauert theory says that the r-th cohomology group of holomorphic section with values in V is finite dimensional and that the cohomology is vanishing if X is q-complete. If E is a holomorphic Banach bundle over X, it is known that the first cohomology group vanishes if X is Stein. Chapter I gives a detailed overview of the work. In chapter II it is shown that there are holomorphic Hilbert bundles over 1-convex manifolds such that the first cohomology of the bundle is not Hausdorff. In chapter III the following finiteness theorem is shown: If E is a holomorphically trivial Banach bundle or a holomorphic Banach bundle of compact type with the compact approximation property over a q-convex manifold X, and if V is a holomorphic vector bundle over X such that the q-th cohomology vanishes, then the following holds true: The q-th cohomology for the tensor product of V and E is finite dimensional. If X is q-complete, then the r-th cohomology vanishes if r is greater or equal q. If r is greater than q, this is shown also for arbitrary holomorphic Banach bundles E. In the appendix it is sketched how for r equal q the L2 method could yield a vanishing theorem for Hilbert bundles.

description: The ability to cross both natural and man-made obstacles have always been crucial for good mobility and is vitally important for various operations. The series of Pontoons are used as floating bridge to allow the transport vehicles and personnel over water and marshy grounds. Floating bridges are cost-effective solutions for crossing large bodies of water with unusual depth. Friction drag is observed when relative motion exists between pontoon and fluid. In view of this drag force is required to be evaluated correctly so that arrangement to fix the pontoon can be accurately designed considering the load and safety factors. For this required to carry out experiment to measure drag forces acting on the pontoons due to water resistance at various weights and water velocities. To study and collect numerous data, three pontoons of various shapes and materials were chosen for experiments. The drag force of pontoons is measured at 0, 5 and 10 degrees by add on various loads and submergence levels. During the experiments, a pontoon freely suspended to Rating Trolley when towed at a predetermine speed in straight open water tank, the drag force induced is measured by precise load cell. Experimental outcomes of all three pontoons for drag forces at 0, 5 and 10 degrees at various submergences and velocities will limit its application in specific velocity range and weight applied on it. Experimental analysis indicates the drag force is directly proportional to the frontal resistive area, water velocity and depth of submergence.
A unified Erdős-Pósa theorem for constrained cycles

description: A doubly group-labeled graph is an oriented graph with its edges labeled by elements of the direct sum of two groups $Γ_1,Γ_2$. A cycle in a doubly group-labeled graph is $(Γ_1,Γ_2)$-non-zero if it is non-zero in both coordinates. Our main result is a generalization of the Flat Wall Theorem of Robertson and Seymour to doubly group-labeled graphs. As an application, we determine all canonical obstructions to the Erdős-Pósa property for $(Γ_1,Γ_2)$-non-zero cycles in doubly group-labeled graphs. The obstructions imply that the half-integral Erdős-Pósa property always holds for $(Γ_1,Γ_2)$-non-zero cycles. Moreover, our approach gives a unified framework for proving packing results for constrained cycles in graphs. For example, as immediate corollaries we recover the Erdős-Pósa property for cycles and $S$-cycles and the half-integral Erdős-Pósa property for odd cycles and odd $S$-cycles. Furthermore, we recover Reed's Escher-wall Theorem. We also prove many new packing results as immediate corollaries. For example, we show that the half-integral Erdős-Pósa property holds for cycles not homologous to zero, odd cycles not homologous to zero, and $S$-cycles not homologous to zero. Moreover, the (full) Erdős-Pósa property holds for $S_1$-$S_2$-cycles and cycles not homologous to zero on an orientable surface. Finally, we also describe the canonical obstructions to the Erdős-Pósa property for cycles not homologous to zero and for odd $S$-cycles.
description: 37 pages. In this version, we correct a small flaw in the proof of Lemma 20 pointed out by Robin Thomas and Youngho Yoo. Hence there is a worse dependence of the parameters in the statement of Lemma 20. This does not affect the overall argument and no parts appearing later in the paper. This flaw also appears in the version published by Combinatorica
Travelling through Guidebooks

description: This article presents a journey through the divided city of Nicosia on the island of Cyprus by confronting its dominant representations in guidebooks dating back to 1960s with my personal urban experience in the northern part of the city, and placing these readings in the context of the delicate political history of the city. This approach provides an account of the extant, the constructed as well as the subjectively remembered and imagined spaces of the city. The act of reading books includes spatial and temporal activities: following the lines, stopping at certain words, jumping through paragraphs, searching for certain images and turning the pages back and forth. These activities, in the case of guidebooks, may evoke spatial memories of textures, lights, sounds, streets, buildings and people. Travelling through the different representations of sites in the guidebooks, and mapping this activity of reading, enabled me to lay out the ways in which traditional guidebooks cause a kind of topographical amnesia by privileging dominant knowledge in relation to places and decontextualizing other knowledges. I have used this multiple reading as a critical topographical practice that can question and dismantle the fixed representations in the guidebooks. Such a critical topographical practice is indeed a practice of writing place, referring to the word’s etymological meanings: toposfor ‘place’ and graphe for ‘which writes’ or ‘is written’. This topographical practice critically and subjectively relates knowledge to place and time. It offers the possibility for me – as a traveller and researcher – to temporarily appropriate real spaces and sustain other future spatial possibilities. With the following pieces of writing about sites in Nicosia, I propose possible but partial narratives of places, which are alternative to the officially acclaimed interpretations present in the guidebooks. My alternative narratives of places offer imagining the ground of the controlled buffer zone as unfixable, dead ends as spaces resisting dichotomies of centre-margin, public-private, and local-occupier, and envisioning the horizon as a continuous extension of boundaries.

description: Cette thèse en création littéraire contient trois parties. La première partie est constituée du texte de création littéraire : Ces jeunes filles parlent trop. Le texte est divisé en trois parties afin de rendre compte d'une parole multiple, comme le titre du texte le laisse penser. La création littéraire est constituée de poèmes en prose et en vers, ainsi que de fragments poétiques. Ce texte de création avait pour objectif d'expliciter la problématique suivante : Comment rendre compte de situations traumatisantes et du corps à travers différents objets? Ainsi le texte présente plusieurs objets dont le miroir, la bouteille et des tresses capillaires. La deuxième partie est divisée en trois chapitres. Le premier chapitre présente une analyse du corps poétique chez Anne-Marie Albiach dans son recueil Mezza Voce. Il s'agit ici de voir de quelle manière Albiach transforme le corps afin de permettre à celui-ci de devenir un objet d'écriture. Le deuxième chapitre aborde Les chants de Maldoror du comte de Lautréamont. Dans ce chapitre, un passage en particulier est analysé. Celui-ci nous servira à présenter de quelle façon le corps chez Lautréamont permet, malgré ses nombreuses mutilations, d'être un outil de transmission et de communication. La dernière partie ajoute une composante réflexive à la thèse. Il s'agira de présenter et d'expliquer la problématique et la thématique choisies. Le dernier chapitre, Création et corps, sert aussi à mettre en lien le texte de création et les auteurs abordés.
Tracing Spatial Values through Poem-Drawing

description: In this article, poem-drawing is proposed as an emotive tool to interweave observations of place, the subjective perception of the architect, and imagined spatial interventions. A composite of two artistic instruments, allows the subjective and the objective dimension in architecture to re-establish their dialogue. In this paper, we aim to exhibit how poem-drawing can: 1. bring urban history into presence by verse-image storytelling; 2. discern how emotions (memories, desires, fears, dreams) related to a place build the urban collective memory; 3. encourage a design approach, sensitive towards the site-specific inherent beauty. Taking the old city core of Ohrid as a case study, we examined its reflection in/through the eyes of three (imaginary) interlocutors: a young pregnant woman in 1944, an eight-year-old girl in 2018 and an old lady in 2084. Through a process of poem-drawing-discussing, we tried to inhabit their personas by writing and drawing our imagined experiences of their storylines. Each cycle of poem-drawings was followed by comparison and evaluation of the written and drawn results according to their relevance for a future spatial intervention. By comparing poem-drawings from three time periods, we aimed to question whether it is possible to reveal which spatial qualities remain absolute, timeless, derived from the specificity of a particular site? With this experimental process, we aimed to find ways of tracing urban history, and to capture site-specific qualities that are difficult to measure by conventional means. By using our own embodied experience, our imagination, and by discussions on our findings, our investigation brought into play stories of the ancestors and the descendants of the citizens of Ohrid.

description: Narratives employed when writing about a place and building a place have a central theme in common: both weave between the human, personal and emotional experience of place and the physical, spatial and atmospheric place – a dialogue between the inner and outer worlds. This article builds upon a lecture given at the University of Zurich’s Department of Literature’s conference Shifting Grounds: Culture, Literature and Spatial Phenomenologies (2016), addressing several explicit uses of literature to inform the design of contemporary urban place. These uses are drawn from practical experience at Studio Vulkan Landscape Architecture, where we use literature to access a deeper understanding of how people perceive and describe their experiences of place as well as descriptions of place. The examples of literature central to our work and the accompanying projects they have informed shed light upon four facets of our contemporary urban landscape and the experience of them: 1. bodily spatial experience, 2. nature, 3. the sensory experience of being in suburban woodland fragments and 4. traffic and sound.

description: In response to financial challenges, there is a strong likelihood that intercollegiate athletic departments will further emphasize attendance growth at football games. It is necessary to ensure future football game attendance in order to sustain non-revenue, Olympic sport programs which have traditionally struggled to be profitable. The purpose of the current study is to identify the most influential factors affecting attendance at football games. The study investigates the relationship between facility, concessions, merchandise sales, pre-game activities, in-game entertainment and other aspects. The students, faculty and staff at a large, public university in the South were selected as participants in this study. The results of the survey (N = 998) were analyzed to determine statistically significance among attendance factors when focusing on the background of respondents. Based on the results, the discussion of each attendance factor focuses on the practical implications for collegiate marketers.

A tireless traveler of European and world universities, he had developed throughout his career a communicating enthusiasm for the Europeanisation of taxation. Combining an indisputable technical competence with an extraordinary capacity for abstraction, he was a university person in the etymological sense of the term, i.e. oriented towards the universal, while at the same time deeply embedded in the political, social and economic reality of his time.

The (Un-) Homely in Bogotá
Creators: name: Weenink, Noortje
Publisher: name: Writingplace
Year: 2018

description: The Architectural Embrace aims to build a metaphorical bridge between socio-economic, political and architectural contradictions in Bogotá by means of a hybrid layer – an alien object in the rigid urban grid of the city, rupturing the existing notions of what and who is valuable in the city. It thus criticizes the current and past practices of neglect and disdain towards the lowest classes of society and explores the role of architecture in challenging political and societal problems. But how does one progress in such a notorious place as El Bronx, where the urban memory is built on transgression and felt by the (architectural) uncanny without erasing the past? How does one respect and commemorate (pre-) existing conditions without dictating a collective meaning? And how does one create an architectural alternative that does not colonize the place? The Architectural Embrace approaches these paradoxes by offering a place of reflection amidst the roaring city life and its power struggles. By means of a new type of architecture, unfamiliar to and disrupting the context and its hierarchies on both urban and architectural scale, the building criticizes existing practices and paves a way toward a new perception of the location. It thus lies on the verge of the uncanny and transgressional space. In The Architectural Embrace, the city of Bogotá is presented with a monumental architecture representing the abolished fourth block of El Bronx. Instead of erasing ‘the hell of Bogotá’, it recognizes the importance of this area in the city and it emphasizes the value of the lower classes of society, while addressing the history of neglect of the location. Thus, as a tool of (and place for) reflection, the project may work as a catalyst for sustainable change and an alternative to the gentrification that brings about a vicious cycle of displacement, decay and demolition in the city.

description: We propose a novel accelerated exact k-means algorithm, which performs better than the current state-of-the-art low-dimensional algorithm in 18 of 22 experiments, running up to 3 times faster. We also propose a general improvement of existing state-of-the-art accelerated exact k-means algorithms through better estimates of the distance bounds used to reduce the number of distance calculations, and get a speedup in 36 of 44 experiments, up to 1.8 times faster. We have conducted experiments with our own implementations of existing methods to ensure homogeneous evaluation of performance, and we show that our implementations perform as well or better than existing available implementations. Finally, we propose simplified variants of standard approaches and show that they are faster than their fully-fledged counterparts in 59 of 62 experiments.

description: This issue of Writingplace Journal, Reading(s) and Writing(s), focuses on the complex process of writing itself, and in particular on the question of reading and responding to texts. By presenting not only resulting texts, but discreet readings of works in process integrated with the discussions that unfold, the issue reveals complex modes of writing that move between the scholarly and the fictional. It draws attention to the questions of authorial voice, the voice of the reader, and the voice of the possible protagonists of the text, even if this as an object, space or indeed, place. If the authors could be said to engage in various acts of ‘writing place’, as per this journal’s general thematic focus, what kinds of places do they bring into existence? Furthermore, which modes of writing are deemed most appropriate in order to create both evocative and critical accounts of places? Driven by a concern to reinvigorate space-related research through the means of writing, the texts in this issue have evolved through the collaborations of a group of affiliated thinkers and practitioners, within a series of reading and writing workshops in the context of the project Transversal Writing.2 Challenging the means and formats of conventional academic writing, this project sets out to transgress the hierarchies between academic and non-academic knowledge, theory and practice, discipline and profession. Contesting the reification of architecture that maintains that the building is a discrete object – whose values are materialized through real estate, limits defined by property borders and agency reduced to profit-making – what we call ‘transversal writing’ traces the lines of connection between architectural conceptions and their effects, between decisions and materializations, forms and affordances. The project acknowledges how architecture is shaped by words, imagery and ideas long before it is transformed into bricks and mortar. Recognizing architecture as a product of the collective imaginary – an act of human creation – is to identify the potentiality in how words, images and physical entities have a capacity to proliferate, spread and generate unforeseeable effects, far beyond the intentions of the architect.

Differences in Parent and Child Experiences of Parents' Racial Socialization Practice
Creators: name: Wallace, Amy L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The current study utilized data for 64 African American adolescents and their parents to investigate the impact of warmth and conflict on parent-child agreement in reports of parental racial socialization. Fathers and children did not tend to agree on reports of parental racial socialization. In mother-child dyads, conflict, rather than warmth, moderated parent-child agreement. Contrary to hypotheses, however, higher levels of conflict were associated with higher levels of agreement. These findings suggest that low levels of conflict in adolescence may be reflective of low parent-child interaction overall whereas, high levels of conflict may indicate a developmentally appropriate healthy parent-adolescent relationship. Recommendations for future research include replication of this study using a larger sample size and further investigation of father roles.

description: This edited ethnographic diary, produced during a research and teaching stint in Cyprus, takes in the island landscape, politics and underlying economic forces dramatically shaping the environment in order to reveal a complex picture across a variety of scales and analytical registers. The aim of this diary is to understand the recent real-estate transactions launched by the Government of the Republic of Cyprus and selling EU-Citizenship in tandem with real estate, particularly as high-end luxury development along the coast. This understanding of land ownership and real estate evolves around the notion of territoriality, which defines territory as a cultural and social product and which includes the Lefebvrian dimension of lived space. The fragmented form of the diary entry will allow to cut across the different registers mentioned above; the work of the editing process will consist in framing the subjective position of the self as a political.

description: By using the fact that the space of all probability measures with finite support can be somehow completed in two different fashions, one generating the Arens-Eells space and another generating the Kantorovich-Wasserstein (Wasserstein-1) space, and by exploiting the duality relationship between the Arens-Eells space with the space of Lipschitz functions, we provide a dual representation of Fenchel-Moreau-Rockafellar type for proper convex functionals on Wasserstein-1. We retrieve dual transportation inequalities as a Corollary and we provide examples where the theorem can be used to easily prove dual expressions like the celebrated Donsker-Varadhan variational formula. Finally our result allows to write convex functions as the supremum over all linear functions that are generated by roots of its conjugate dual, something that we apply to the field of Partially observable Markov decision processes (POMDPs) to approximate the value function of a given POMDP by iterating level sets. This extends the method used in Smallwood 1973 for finite state spaces to the case were the state space is a Polish metric space.

Isle of Islay - Nature Observatory

description: This graduation project is a social critique against the overrule of rationality over humanity, a frustrated plea for more emotional capacity (for love and nature) within (or beyond) a rational world. To overcome the conditions and paradox described above, I have developed various fictive concepts or utopias. The project here is one of such concepts, and perhaps also a radical and pessimistic one. The protagonist takes his frustration with an escapist attitude, leaves his city behind and tries to find his joy and purpose of life in a natural and prescientific environment. He arrives at a faraway island in Scotland, where natural elements, not rational human beings, are the dominating force. I designed various instruments or observatories for the modern man to get in touch with what he yearns for – nature: through folklores and tales he regains a prescientific eye; through the instruments, he experiences the varied elemental existence of nature – sun, moon, stars, water, fire, wind, waves . . . During this project I got inspiration from reading, writing and collecting. Travel logs written by English scholars, who travelled to Scotland in the eighteenth and nineteenth centuries, as well as folklore and tales of the Scottish islands were great inspirations; like a time machine, these words took me a few hundred years back to a prescientific state of mind.

description: We establish a combinatorial connection between the real geometry and the $K$-theory of complex Schubert curves $S(λ_\bullet)$, which are one-dimensional Schubert problems defined with respect to flags osculating the rational normal curve. In a previous paper, the second author showed that the real geometry of these curves is described by the orbits of a map $ω$ on skew tableaux, defined as the commutator of jeu de taquin rectification and promotion. In particular, the real locus of the Schubert curve is naturally a covering space of $\mathbb{RP}^1$, with $ω$ as the monodromy operator. We provide a local algorithm for computing $ω$ without rectifying the skew tableau, and show that certain steps in our algorithm are in bijective correspondence with Pechenik and Yong's genomic tableaux, which enumerate the $K$-theoretic Littlewood-Richardson coefficient associated to the Schubert curve. We then give purely combinatorial proofs of several numerical results involving the $K$-theory and real geometry of $S(λ_\bullet)$.

description: Current best local descriptors are learned on a large dataset of matching and non-matching keypoint pairs. However, data of this kind is not always available since detailed keypoint correspondences can be hard to establish. On the other hand, we can often obtain labels for pairs of keypoint bags. For example, keypoint bags extracted from two images of the same object under different views form a matching pair, and keypoint bags extracted from images of different objects form a non-matching pair. On average, matching pairs should contain more corresponding keypoints than non-matching pairs. We describe an end-to-end differentiable architecture that enables the learning of local keypoint descriptors from such weakly-labeled data. Additionally, we discuss how to improve the method by incorporating the procedure of mining hard negatives. We also show how can our approach be used to learn convolutional features from unlabeled video signals and 3D models. Our implementation is available at https://github.com/nenadmarkus/wlrn

description: La sentencia del TJUE de 24 de marzo de 2022 concluye que en el caso de inicio de la circulación intracomunitaria de productos sometidos a los documentos de acompañamiento y a causa de un fraude de terceros el destinatario lo desconociera, es aplicable el régimen suspensivo de los IIEE, siempre que las autoridades competentes no hayan detectado la irregularidad. La existencia de una garantía constituida por el depositario autorizado a efectos de dicha expedición precise el nombre del destinatario autorizado, pero no su condición de operador registrado no afecta a la regularidad de tal circulación. Con esta sentencia, el TJUE establece una jurisprudencia similar a la responsabilidad del depositario, en la cual sentenció que era objetiva por su participación en la actividad económica y no se basaba en la culpabilidad. Esta jurisprudencia se debe tener presente en la interpretación de la normativa española en el régimen suspensivo de los IIEE en el caso de irregularidades en la circulación intracomunitaria de los productos sujetos a los IIEE y en los posibles efectos que pueda tener en el IVA.

title: Numerical Modeling for Optimization of the Aspect Ratio of Submerged Vanes for the Purpose of Sediment Deflection in Rivers

description: In order to create a secondary circulation (spiral flow) in the downstream direction to their trailing edge, submerged vanes are tiny aspect ratio (H/L) devices that are positioned vertically on riverbeds. Since this secondary circulation is driven by the vane-induced tip vortex, submerged vanes are best recognized for changing the alluvial river-bed profile. Finding the right aspect ratio as a function of the angle of attack with the approach flow is one of the current issues with using the submerged vane technique. In this context, the current study aims to investigate the best vane length to be used, based on a specific angle of attack with the flow. A pair of rectangular vanes with a set height is among the studied vanes. Only 150 and 400 angles will be examined in the current study because these are the ideal minimum and maximum recommendations made by earlier studies. The vanes' length to height ratios that were taken into consideration for this investigation were 2, 3, and 4. The purpose of the study is to determine how these variables affect the strength of the secondary circulation and sediment deflection downstream of the vanes. The flow field around and past the submerged vane is investigated using the Flow-3D Hydro numerical model. The most ideal aspect ratios for a low Froude number of 0.168 are 0.25 and 0.33 at 40 and 15 degrees of attack, respectively. The most ideal aspect ratios with a high Froude number of 0.303 are 0.33 and 0.25 at 40 and 15 degrees of attack, respectively.

title: Bank Scour Protection Using Spur Dyke in a Meandering Channel Under Low Flow Velocity

description: In geophysical flows, the channel often starts to meander when it encounters a plan terrain. Owing to higher flow velocity, it tends to erode the channel boundary (bed and banks) that comes across its path. Scouring in a meandering channel primarily depends on channel boundary, flow condition, and sediment properties. To date, numerous works have been conducted to understand the velocity distribution and scouring pattern in a meandering channel under varying discharge conditions. However, only a handful of work has been reported on the scour pattern under low discharge conditions in a meandering channel. Therefore, in this paper, an experimental study was conducted under a very low discharge in an 80° (central angle θ) bend to analyse the scour pattern. Investigation of the scour profile reveals that maximum scour occurs at the downstream side of the bend apex rather than the bend apex. Hence, an attempt has been made to counter the scour using the spur dyke. In doing so, a non-submerged spur dyke was installed at three different locations θ = 0°, 40°, and 60° of bends with three orientations α = 60°, 90°, and 120° for approaching and developed flow conditions to identify the best location and orientation of the spur dyke. Observation suggests that spur dyke at θ = 60° with α = 90° and spur dyke at ‘θ’ = 40° with ‘α’ = 60° provide the best results for approaching and developed flow conditions, respectively, in terms of preventing scour under low flow velocity.
The Translation of Dreams. Psychoanalytic and Poetic Devices in South African Architectural Education

description: There are two kinds of dreams. There are the dreams that we share, and there are dreams that are our own. Architecture, and the politics of dreams – or the dreams of politics, for that matter – form the context of this essay, and in particular how this thematized a design project in South African architectural education. In the South African context, where the past is often experienced as a nightmare, a fundamental inquiry into the precepts of architectural design and shared history has the potential to relocate repressed events of trauma. These events, which currently exist primarily in the historical record, can be translated into the present, and shown to still be active, but exerting their effects surreptitiously. This essay aims to presents brief readings of three design-research projects conducted in Unit 11 of the Graduate School of Architecture (GSA) at the University of Johannesburg. A number of projects are being developed which work through (rather than resolve) concerns of material memory, cultural edifices and politics, employing metaphors of ghosts, nightmares, phantom limbs, exquisite corpses and plastic identities. By illustrating (or designing) such conditions, the unit attempts to bring to the surface some of the historical fragments haunting the South African collective subconscious. Design-research students are encouraged to make associations more or less freely in the early stages of the design process, after which, through critique, reflexive relationships are established between designed work and its interpretation. The unit makes extensive use of allegory and figuration to create a slight distance between the students’ immediate frame of reference and the complex political realities with which the projects are entangled. This method allows students to expose and interrogate their biases and proclivities. The projects define architecture as a collective dream, condensing, sorting and forgetting our (shared) history.

Lighthouse: Dwelling on a Remote Island. A Bachelor Diploma Project within a Narrative Framework

Year: 2018

description: Within this article, a curious storyteller will guide our way to remotely situated islands and their marvellous stories and stubborn inhabitants, invented by students. In the summer of 2016, the bachelor diploma students of the department of Wohnbau at the RWTH-Aachen University were asked to develop a dwelling for a lighthouse keeper, a house with a beacon. Within this article, we aim to give an insight into the project’s boundaries, by describing the project brief and our tutoring approach. With this article and the introduction of our own curious narrator, we intend to show how our approach has resulted in a great variety of narrated tales that were combined with profound building techniques and methods. The literary framework of the assignment, departing from a place that could not be visited and from a particular character, made the student's observations and readings of both programme and context extremely focused. The students explored their islands and treated the challenges for their protagonist to dwell on them in an accurate manner. They became sensitive to basic conditions of dwelling, such as landscape, climate, materials, building methods, and applied these conditions in their distinctive and tangible design solutions. In addition, the game rules of the entire project, in combination with the detailed requirements for the final presentation, helped to examine the skills and knowledge we deem indispensable to obtaining the bachelor’s degree. The students gained the understanding necessary to handle a relatively small architectural design project from concept to detail through imagining their own narrative framework and making their unique design of a lighthouse the starring role of their very peculiar and fantastic story.

description: Consider the problem of sparse clustering, where it is assumed that only a subset of the features are useful for clustering purposes. In the framework of the COSA method of Friedman and Meulman, subsequently improved in the form of the Sparse K-means method of Witten and Tibshirani, a natural and simpler hill-climbing approach is introduced. The new method is shown to be competitive with these two methods and others.
title: An Experimental Study on Scour at Zero Degree Confluent Channels

description: This paper presents an experimental study on scour depth at the confluence of a mobile and a rigid bed open channel. Substantial momentum difference between the confluent channels controls flow hydrodynamics and mixing in the confluence hydrodynamic zone. Scour at the confluence of the channels is a threat to the stability of the structure separating the two channels. Results for bed morphology and maximum scour depth at the confluence for different hydraulic and geometric conditions in the channels are presented. Data analysis shows that the discharge ratio (ratio of discharge in mobile bed and total discharge downstream) and tailwater conditions are key factors affecting the bed morphology and maximum scour depth. The maximum scour depth decreases by increasing the discharge ratio and tailwater depth.
