description: The construction of gauge theories beyond the realm of Lie groups and algebras leads one to consider Lie groupoids and algebroids equipped with additional geometrical structures which, for gauge invariance of the construction, need to satisfy particular compatibility conditions. This paper analyzes these compatibilities from a mathematical perspective. In particular, we show that the compatibility of a connection with a Lie algebroid that one finds is the Cartan condition, introduced previously by A. Blaom. For the metric on the base M of a Lie algebroid equipped with any connection, we show that the compatibility suggested from gauge theories implies that the (possibly singular) foliation induced by the Lie algebroid becomes a Riemannian foliation. Building upon a result of del Hoyo and Fernandes, we prove furthermore that every Lie algebroid integrating to a proper Lie groupoid admits a compatible Riemannian base. We also consider the case where the base is equipped with a compatible symplectic or generalized metric structure.

Foray in a Modern Reserve
Creators: name: Wilson, Robin
Publisher: name: Writingplace
Year: 2020

description: During research for the Arts Council funded project East Sussex Modern (2016), Photolanguage (Nigel Green & Robin Wilson), visited sites relating to the legacy of the modernist Borough and Water Engineer Sidney Little (1885-1961) in the county of East Sussex, U.K.. These included the impounding reservoirs of Powdermill (1932) and Darwell (1949). The landscapes surrounding the reservoirs have evolved into mature woodland nature reserves and represent complex terrains of land-use and property ownership. ‘Foray in a Modern Reserve’ (Part I), an image and text ‘portrait’ and re-imagining of these terrains, is a composite text, an assemblage of diverse texts of occupiers and users of these terrains over time, from Photolanguage’s own observations made on site visits, to the archival records of Sidney Little’s description of the reservoir infrastructure, to the accounts of UCL archaeologists, Angling and Ramblers clubs and local landowners. It is a vehicle through which to explore an experimental method of spatial writing at the intersection of archival research, visual and textual documentary practice, and visual and textual fiction-practice. Imagery interplays with the text’s narrative structure to generate its own narrative and descriptive trajectories. Through the combination of different modes of the landscape’s description, through its successive spatialization across different agendas of movement and occupation, ‘Foray in a Modern Reserve’ constructs a utopic portrait of the modern reservoir reserve. As a composite text, it traces the intersection and dispersal of desire and agency across the terrain as an ‘inspection’ that must discover and construct its own object, and propose its own figural ‘solution’ to the landscape’s latent equations.

description: We analyze the learning properties of the stochastic gradient method when multiple passes over the data and mini-batches are allowed. We study how regularization properties are controlled by the step-size, the number of passes and the mini-batch size. In particular, we consider the square loss and show that for a universal step-size choice, the number of passes acts as a regularization parameter, and optimal finite sample bounds can be achieved by early-stopping. Moreover, we show that larger step-sizes are allowed when considering mini-batches. Our analysis is based on a unifying approach, encompassing both batch and stochastic gradient methods as special cases. As a byproduct, we derive optimal convergence results for batch gradient methods (even in the non-attainable cases).

Su establecimiento se justificó en la lucha contra el fraude fiscal. Para el Tribunal de Justicia de la Unión Europea, aunque la lucha contra el fraude y la evasión fiscal pueden ser razones que justifiquen medidas que restrinjan las libertades fundamentales, dichas medidas han de ser adecuadas a los objetivos perseguidos y no ir más allá de lo necesario para alcanzarlos. El análisis de esta sentencia y sus consecuencias es el objeto de este trabajo.

Choices and Strategies of Spatial Imagination

Year: 2020

description: Architecture is by definition an act of spatial imagination, this wondrous capacity to envision possible futures for the built environment. Spatial imagination is essential in order to visualize new constructions taking shape, evolving in time, and partaking of the cultural expression of a place or era. It takes spatial imagination to foresee how architecture can meaningfully contribute to people’s lives, providing a sense of belonging, space for their needs and dreams. Nonetheless, spatial imagination is oftentimes hard to trigger or difficult to control. Imaginative ideas often emerge unexpectedly, when seemingly unconnected or contradictory words, images and thoughts are brought together. Spatial imagination, just like the creative act of writing, seems to reside in ‘the lightning flashes of the mental circuits that capture and link points distant from each other in space and time,’1 as Italo Calvino poetically claims. The topic of this fourth issue of Writingplace journal, Choices and Strategies of Spatial Imagination, ‘links points distant from each other’, by connecting texts from different disciplines with architectural design, in order to study imagination. This issue starts from a paradoxical observation: although we recognize, almost spontaneously, the paramount role spatial imagination plays in the creation of an inspired built environment, there is admittedly limited emphasis on the detailed study of this creative imagination in the field of architectural research. Moreover, a lack of rigorous reflection on the key role of spatial imagination in addressing the urban and architectural issues that are currently at stake in our societies can be detected across all of the design disciplines. For example, there is surprisingly little attention for how specialties outside architecture can inform or inspire the proliferation of spatial imagination. It seems, as William Whyte argued, that we have forgotten that ‘we are always translating architecture: not reading its message, but exploring its multiple transpositions’. The issue focuses precisely on different kinds of transpositions between written forms of imagination and architecture, but without defending the popular belief that we should read architecture as a polysemic text and start to think in terms like ‘architexture’ or ‘polygraphy’ when analysing architecture culture.

Reactions to Wellness Initiatives: A Digital Ethnographic Study of Medical Student Reddit
Creators: name: Robinson, Daniel Wellington
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Studies show that medical training is fraught with burnout and wellness issues. As a result, numerous medical schools have developed wellness initiatives hoping to prevent burnout in their students. However, it is not well known how medical students react to these initiatives. Using digital ethnographic methods, this study sought to examine how medical students who engage in online discourse on Meddit (medical student Reddit), reacted to institutional wellness initiatives. We found that medical students on Meddit frequently discussed burnout and wellness though the lens of their lived experiences, describing their personal struggles with school and mental health, feelings of being unwell, and specific challenges they encounter. They also highlighted structural and institutional consequences demonstrating that institutional support does not appear to be improving burnout. Understanding the way that medical students view burnout and wellness is integral to finding solutions to burnout in medical education. We found that current institutional initiatives are not blending well with how medical students understand their own education in the face of widespread burnout.

title: Designing Smooth Mixed-Geometry Canal Transition
Creators: name: Froehlich, D. C.
Publisher: name: Utah State University
Year: 2023

description: When a canal’s size or shape changes, usually over a short distance, a section of the channel, known as a transition structure, is needed to connect the waterway’s two stretches. Fifth-degree parametric equations are developed to calculate the cross-section dimensions and bed centerline elevations (thus, the geometric surface coordinates) between the two ends of a warped transition structure in a water-supply canal. The parametric modeling approach provides a smooth representation of the mixed geometry that results from terminal sections having vastly different shapes. A generalized cross-section defined by four parameters enables a straightforward model of various forms ranging from trapezoids to semi-circles. This approach significantly simplifies the interpolation of surface coordinates between the terminal points of a transition structure. It also maintains a smoothness that helps avoid undesirable consequences of channel contractions and expansions. An example is presented that applies the parametric modeling approach to design a significant canal transition where the cross-section changes from a standard trapezoidal shape with rounded bottom vertices to a rectangular section in a steeper aqueduct that carries the flow across a broad valley.
The World and the Cave
Creators: name: Teerds, Hans
Publisher: name: Writingplace
Year: 2020

description: Imagination, Hannah Arendt argues, is the human capacity to mentally remove oneself and see things from a different perspectives. It allows to imagine how things can be different. As such, this capacity is as much the source of political action as well as of architectural design. Architectural imagination - as well as understanding - might flourish when fed by perspectives from other professional fields, like philosophy, social sciences, theology, as well as other artistic fields, like literature, painting, and sculpture. In this paper, Hans Teerds proposes an exemplary reading beyond the borders of the architectural profession by means of a comparative reading of Hannah Arendt’s 1958 The Human Condition and the novel The Cave (2000) by the Portuguese writer Jose Saramago. By reading them together, this paper explore perspectives upon public space, mass consumption and production, and craftsmanship, which, highlight political aspects of architecture.

title: Reynolds Stress Modelling of Supercritical Flow in a Narrow Channel

Publisher: name: Utah State University
Year: 2023

description: One of the most effective techniques to combat reservoir sedimentation, especially for small to medium-sized reservoirs, is the installation of Sediment Bypass Tunnels (SBTs). SBTs are designed for supercritical narrow open channel flow conditions. In such narrow channels, the walls and the free surface boundaries can influence the flow characteristics and form secondary currents. These vortex structures can alter the longitudinal velocity distribution and form velocity dip. Besides, they can also alter the bed shear stress distribution and influence the sediment transport. Such complex phenomenon can be modelled using Reynolds Stress Models (RSMs). In this study, the full Launder Reece and Rodi (LRR) pressure-strain model was implemented in OpenFOAM® and the simulated results were compared with former experimental results for flow depth = 0.16 m, Reynolds number = 5.7×105, Froude number = 1.84, and channel aspect ratio = 1.25. In addition, the dissipation rate of turbulent kinetic energy at the free surface was modelled following literature. The simpleFoam solver, which is based on the SIMPLE algorithm, was used for the steady state simulation. The predicted velocity distributions, secondary currents, velocity dip, turbulence intensity distributions, and lateral variation in bed shear stress are consistent with literature. The results show that the simulated maximum longitudinal velocity and the cross-sectional average bed shear stress are 0.34% and 0.74% lower than the observed values. An intermediate vortex was developing between the free surface vortex and the bottom vortex for the tested case. However, it remained as a part of the free surface vortex.
Fidelity and Freedom in the Theory of Adaptive Reuse
Creators: name: Van Cleempoel, Koenraad
Publisher: name: Writingplace
Year: 2020

description: This essay contributes to the emerging theory of adaptive reuse of architectural sites by borrowing vocabulary that relates to the transposition between architecture and translation. Three aspects seem relevant in both disciplines: (1) carrying over meaning with respect for (2) tradition and (3) craftsmanship. In the process of adaptive reuse, buildings often receive a new program entailing shifts of meaning; hence the analogy with the art of translation. In addition to this negotiation of meaning, an attitude to tradition is also a valuable lens to approach this transposition between architecture and translation. In particular the dialectic process between fidelity and freedom. Walter Benjamin’s essay The Task of the Translator (1921) and T.S. Eliot’s Tradition and the Individual Talent (1919) offers richness and accuracy to the growing vocabulary on adaptive reuse. The essay illustrates this argument by looking at the remodeling of a 1859 prison into a Faculty of Law of the University of Hasselt in Flanders. The case study wants to illustrate this process of making both the original and the translation recognizable as fragments of a greater language. The enclosed typology of the prison was changed into an open, urban-oriented faculty of law. It shows us how memory can be both a generous database as well as a selective process. How memory and oblivion are two essential conditions for architecture to negotiate with heritage.

Forms of Utopia
Creators: name: Culek, Jana
Publisher: name: Writingplace
Year: 2020

description: “Forms of Utopia” is part of a larger research investigating critical and speculative methods used in architectural and literary utopian and dystopian works of the 20th century. It presents one of several case study pairings featuring a work of architectural and literary fiction, which were created within a similar historical and societal context and which deal with similar issues. The text investigates and juxtaposes two fictional worlds created in the first part of the 20th century, namely Ludwig Hilberseimer’s architectural proposal Metropolisarchitecture, and Yevgeny Zamyatin’s literary work We. Taking into consideration various issues which arise while examining works from two different fields, a comparative method was devised which combines approaches taken from both the literary and architectural field. The developed method is based on a combination of Carline Levine’s approach proposed in her book Forms: Whole, Rhythm, Hierarchy, Network (Princeton UP, 2015) and an architectural typological analysis. By using this method, the text examines various forms and patterns of spatial and social experience which are described in the works and through which the utopian and dystopian worlds are structured. Focusing on two main types of forms identified by Levine – namely bounded wholes and rhythms – the text distills common threads, investigates how the authors propose and generate a built and social environment, and how this environment is ideologically and critically charged. While examining the various social and spatial forms which are used to build both fictional worlds, the text also explores the fact that, even though the two worlds are sometimes based on same spatial forms, one author views his project as utopian while the other proposes a dystopian future.

Skopje: The Multiple Faces of the City
Creators: name: Havik, Klaske
Publisher: name: Writingplace
Year: 2019

description: This contribution offers a series of lyrically framed observations of an architectural educator on repeated visits to the city of Skopje. It reflects on the complex histories and processes shaping the city, from the remnants of the Metabolist city to the neo-classical vocabulary of a reconstituted national identity. Historically, the city of Skopje has been characterized by a series of urban abruptions: from the earthquake of 1963 via the end of Yugoslavia and the Balkan wars, to the recent tensions between nationalist tendencies and the growing migrant population from Kosovo and Albania. These abruptions have resulted, on an urban and architectural level, in a great number of spatial contrasts: the fine spatial grain of the old bazaar area as opposed to the large metabolist urban scheme, introduced by Japanese architect Kenzo Tange after the 1963 earthquake; the contrast between the two sides of the river Vardar; the surreal Skopje 2014 project which consisted the erection of fake neo-classical buildings, fountains and an “arc of triumph” on prominent sites across the city, aiming to establish a heroic nationalist narrative of the ancient Macedonia of Alexander the Great. The contribution is composed of a series of fragments which aim to reveal, through the perspective of different characters, both a story line about the urban transformations in Skopje, and an account of spatial practices of everyday life.

Lightness of a Higgs Boson and Spontaneous CP-violation in the Lee Model: An Alternative Scenario
Creators: name: Mao, Ying-nan

Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Based on the weakly-coupled two-Higgs-doublet model with spontaneous CP-violation (named Lee model) and the mechanism to generate the correlation between smallness of CP-violation and lightness of scalar mass, as we proposed earlier, we predicted a light CP-mixing scalar $η$ in which pseudoscalar component is dominant. It is a natural scenario in which $m_η\sim\mathcal{O}(10\textrm{GeV})\ll v$. Masses of all other scalars ($h$, $H$, $H^\pm$) should be around the electro-weak scale $v$. Among them, the 125 GeV Higgs ($h$) couplings are standard-model like, and the charged Higgs ($H^\pm$) mass should be around the heaviest neutral scalar ($H$) mass. We discussed all experimental constraints and showed that this scenario is still allowed by data. The strictest constraints come from the experiments of the flavor-changing processes and the EDM of lepton and neutron. We also discussed the future tests for this scenario. It is possible to discover the extra scalars or exclude this scenario at future colliders, especially at the LHC and $e^+e^-$ colliders with $\mathcal{O}(\textrm{ab}^{-1})$ luminosity. We also pointed out that the $Z$-mediated Higgs pair production via $e^+e^-\rightarrow h_ih_j$ ($h_i, h_j$ stand for two of the $η, h, H$) would be the key observable to confirm or exclude CP-violation in Higgs sector. The sensitivity to test this scenario is worth further studying in greater detail.

description: Rivers are the lifeline for every country as they provide water for proliferation, sustenance and propagation of life
since time immemorial. With increasing population pressure, water demand increased for drinking, irrigation, and industrial consumption. This water deficit required utilization of available water resources in the best possible manner through various hydrological projects like construction of dams, weirs, barrage, etc. There is a disparity in water availability between north and south India as most of the perennial rivers are situated in the north while seasonal rivers in south India. To resolve this disproportionate distribution and to maintain the balance of water between flood and drought-prone rivers, interlinking of rivers is proposed. This proposal has garnered a lot of attention from scientists and environmentalists around the world. These human interventions affect the ecological flow of rivers. There are various risks associated with these projects which require prior assessment. In this study, risks and environmental hazards associated with river projects in India have been discussed with a special focus on the ongoing river projects like the interlinking of rivers. Various factors which determine the feasibility of the proposed projects were studied. There are many risks associated with the change in gradient and environmental flow of rivers with the construction of such projects. We have reviewed risks on humans, like displacement of population and impact on their livelihood as reported for various projects. There are various social implications of such projects which need to be assessed and their mitigation measures need to be undertaken.
Investigation of the role of root flavonoids in the interaction of chickpea with nitrogen-fixing symbionts and parasitic nematodes
Creators: name: Nanayakkara Vithanage, Upul
Publisher: name: The Australian National University
Year: 2023

description: Legumes can get infected by both symbionts and parasites, often concurrently, in the field. Rhizobia (Mesorhizobium ciceri)-legume (Cicer arietinum) symbiosis and rhizobia-nematode (Meloidogyne javanica) parasitism are linked as there are commonalities during the early signal interaction between host roots and both microbes. For example, attraction of rhizobia to the root and the activation of nodulation genes are controlled by exudation of flavonoids from the legume root into the soil. Movement of nematodes into the root can also be affected by flavonoids, although flavonoids generally have a repellent activity. In addition, the two interactions are expected to compete for nutrients in the root. Previous studies have generally found negative interactions of symbiosis with nematode parasitism in legumes, however, it is not known if this is the case in chickpea, a major grain legume grown in Australia. In addition, it is not known to what extent flavonoids control the early interaction of the root with rhizobia and root knot nematodes. Therefore, we hypothesised that rhizobia and nematode parasitism have an effect on each other in the plant, possibly through the induction of specific flavonoids that control the early interaction with both organisms. Rhizobia induced some specific flavonoids when they infect the plants. They are 2'-O-methylisoliquiritigenin, naringenin, formononetin, 7,4'-dihydroxyflavone, liquiritigenin, isoliquritigenin and kaempferol. In contrast, nematodes induced 6,7,4'-trihydroxyisoflavone, afromosin and morin. Interestingly, most of these flavonoids were not induced when both these organisms infected the plant together. This implied that the flavonoid production of the host is altered when rhizobia and nematodes infect plants concurrently. Nodulation gene induction assays showed no significant effect of any of the induced flavonoids as nod gene inducers. Motility assays with nematodes found only one flavonoid with inhibitory activity, but only at very high concentrations. Phenotyping results revealed that the symbiosis with rhizobia had no effect on parasitism and vice versa in plant growth assays. Evaluation of root and shoot biomass, seed yield numbers of infection structures (nodules and galls), amount of fixed nitrogen and total nitrogen showed no significant changes with inoculation of rhizobia or nematodes, inoculated in any order. In addition, short term experiments to evaluate the number of early infection structures found no evidence that infection of roots with rhizobia and nematodes together altered the number of infection structures compared to roots infected with each organism alone. Altogether, this thesis found no evidence of interaction of rhizobia and nematodes in roots of chickpea under the conditions tested, and no evidence for the role of chickpea root flavonoids in the early signaling with rhizobia and root knot nematodes.
Belgrade Baroque
Creators: name: Jobst, Marko
Publisher: name: Writingplace
Year: 2019

description: This text, composed of two layers, brings together queer auto-fictions with the architectural histories of an elusive Serbian Baroque in the city of Belgrade. It explores the issues of heteronormativity, nationhood and religion. It is an autofiction that places special emphasis on the siting of memories in Belgrade, Serbia – Yugoslavia as it was – and focuses specifically on the Cathedral Church of Archangel Michael, one of the rare examples of what could be understood as second generation Baroque architecture in the orthodox Christian country. The desired aim of the broader project is to perform an act of queering of the Serbian ideological, national and religious frameworks, of Belgrade and its buildings, and of academic modes of relating architectural and urban histories. An aspect of this process was the approach to illustrations, which are textual: the footnoted fragments that run alongside the main narrative thrust of the text are simultaneously its illustrations and their own captions. Sometimes reflexive, at other times tangential, they hint at a second level of research that lies beneath the seemingly literary treatment of the piece.

Decolonizing Your Island Imaginary
Creators: name: Frichot, Hélène
Publisher: name: Writingplace
Year: 2019

description: Hélène Frichot’s contribution offers an approach to decolonising through fiction, where cross-generational memories of family life in the Seychelles are used to critically illuminate colonial histories. The function of this experimental essay is to offer a preparatory test-site for a future project that may, or may not, come to fruition. What is at stake are processes of decolonisation, specifically of spatial memories, including the residual hold of colonial imaginaries and how these might be creatively critiqued. The story begins on an apparent island paradise, in the grounds of a colonial plantation house coloured sepia, shades of mahogany and amber hue, as all the world seemingly sleeps its way through siesta. An encounter is witnessed between a returned colonial brother and a younger sister the aftermath of which will concatenate through the following three parts of the projected novella. The second part takes place in Perth, the most geographically isolated city in the world, in hyper-saturated Super-8 colours, brilliant fuchsias, lilacs, yellows and blues. Following an evening of sun darkened children’s’ limbs lingering on a makeshift tarpaulin picnic blanket laid out on a backyard of buffalo grass, two girls sneak into the depths of a migrant family home, into an aunt’s closed bedroom to paint their faces in eyeshadows and lipsticks, only to be suddenly discovered. Part three is sketched in cold translucent greys, and deep brown shadows, witness to a young woman venturing far from home. She is hosted by a reclusive family member in an old apartment on Rue Buffon overlooking the Jardin des Plantes, as she prepares herself for a year of study in a far-off land that is both familiar and strange. Sitting in a stone courtyard on campus, holding a book between her hands – attended on the right by the statue of a poet, and on the left by the statue of a biologist – she hears a noise as though the long-lost sea were approaching her. A massive swell of student bodies floods the courtyard, taking her up in its wake. She recognizes the voice of someone who cries out: It is Forbidden to Forbid! Finally, at the centre of Empire in royal blue, indigo, and chalk with burnt orange highlights, a moment of culmination will be discovered. Temporal registers begin to slip and slide: a young man suffers a humiliating sexual encounter as an older man is confronted ascending from the basement flat of a government in exile. A suite of colonial imaginaries is, from one scene to the next, composed and decomposed through processes of decolonisation. The text is introduced by a reading compiled by Kim Gurney

title: Investigation on Near Bed Flow Features Over a Water-Worked Gravel Bed
Creators: name: Padhi, Ellora
name: Agrawal, Nishank
Publisher: name: Utah State University
Year: 2023

description: One of the key problems in the research on fluvial hydraulics is to correctly reproduce the flow dynamics over a riverbed in laboratory experiments. Generally, while performing experiments, attention is paid to specific hydraulic conditions related to the flow regime, sediment transport, and bed erosion. In this context, the sediment size of the riverbed to be analysed plays an important role. It is a common practice to create the bed manually using a screeded mixture of sediments with random orientation that could be very different from that observed in natural riverbeds. To overcome this issue, a manually created gravel bed is required to be water worked before performing the experiments to get a bed surface, which resembles to that of a natural gravel bed river. Such a bed is termed as water-worked gravel bed (WGB). In recent past, even though the bed topography of WGB has been intensively studied, its effects on the flow features, which govern the near-bed flow field, are still to be explored under varying flow rates. In this study, the double averaged (DA) turbulence characteristics such as velocity, Reynolds shear, and normal stresses, and form induced shear and normal stresses, are analysed for three different flow rates. A comparative study infers that with an increase in flow rate the magnitude of all flow features increases, especially in the near-bed flow zone. The reason for such occurrence is attributed to a higher flow rate that enhances the near-bed turbulence, and in turn the velocity fluctuations.

description: Density matrix quantum Monte Carlo (DMQMC) is used to sample exact-on-average $N$-body density matrices for uniform electron gas systems of up to 10$^{124}$ matrix elements via a stochastic solution of the Bloch equation. The results of these calculations resolve a current debate over the accuracy of the data used to parametrize finite-temperature density functionals. Exchange-correlation energies calculated using the real-space restricted path-integral formalism and the $k$-space configuration path-integral formalism disagree by up to $\sim$$10$\% at certain reduced temperatures $T/T_F \le 0.5$ and densities $r_s \le 1$. Our calculations confirm the accuracy of the configuration path-integral Monte Carlo results available at high density and bridge the gap to lower densities, providing trustworthy data in the regime typical of planetary interiors and solids subject to laser irradiation. We demonstrate that DMQMC can calculate free energies directly and present exact free energies for $T/T_F \ge 1$ and $r_s \le 2$.

description: This text of creative nonfiction follows the making of a film set in Cape Town – how it is assembled, where it goes, what it becomes, how it gets dis-assembled and recycled into other forms. It does so from the perspective of the set-builders, the architects of scaffolding for commercials and other events. The research includes observation, formal interviews and visual documentation. This particular set- build for an insurance client becomes a human-tiered cake, a door that swings open into another dimension, and a manhole cover that becomes a portal. Alongside, a former theatre set reincarnates into a festival late-night venue. The set acts as a prosthetic, a stand-in which straddles the liminal space of both making it and faking it. More deeply, the storyline considers the role of human ingenuity in a world where the handmade object gets repurposed into a techno-aesthetic device. The backstage viewpoint is pointedly focused upon how blue-collar artisans navigate logistics, scale and complexity to create inventive forms, and how their onward trajectories become enfolded into speculative circuits. It is also a story about place: the set-building workshop is located in a former train depot in a semi-industrial precinct facing urbanization pressures while the film studio is a Hollywood-esque hub of cutting-edge technologies. This story, in short, is about conjuring new imaginaries from a Cape Town site of making and how this may speak to a future world of work. The text is introduced by a reading compiled by Catharina Gabrielsson

La configuración jurisprudencial a nivel nacional y europeo del principio de proporcionalidad en el establecimiento de sanciones tributarias

description: El principio de proporcionalidad no es un principio general del Derecho meramente teórico sin demasiada aplicabilidad práctica sino que, por el contrario, los tribunales nacionales y europeos vienen utilizándolo de forma constante para valorar si determinadas conductas de los poderes públicos nacionales vulneran o no los derechos y libertades consagrados en los distintos textos normativos, en concreto, en cuanto al establecimiento e imposición de sanciones a través del ius puniendi de los Estados. Aunque es comúnmente reconocido que todas las sanciones, en general y, en particular, las tributarias han de ser proporcionadas a la reprochabilidad del injusto típico llevado a cabo por el sujeto infractor, el contenido que del principio han ido perfilando los tribunales nacionales y supranacionales no ha sido uniforme. En este trabajo nos proponemos, por tanto, examinar la jurisprudencia constitucional y europea existente en torno al principio de proporcionalidad en el establecimiento de sanciones tributarias para detectar las diferencias presentes entre los niveles de protección constitucional y europeos y constatar si nuestro Tribunal Constitucional cumple con los estándares de protección que establecen los tribunales europeos.

description: A partly unlined pressurized gallery supplies water to a hydropower plant. Since rocks and gravel may detach from the
gallery walls, two gravel traps have been built on the gallery invert, downstream of the unlined sections. During gallery and powerplant inspections, it appears that the gravel traps are empty while gravel is found in the tail channel downstream of the turbines. Clear evidence of turbine damaging by solids impact is also observed. To understand why the gravel traps are ineffective and to define solutions to be implemented on site to increase their trapping efficiency, a 1:7.7 scale physical model of the gravel traps has been built and operated. The tests clearly demonstrated that the short-term trapping efficiency of the gravel traps is good since 98% of the gravel arriving upstream falls into the traps. However, the gravel traps are ineffective in keeping the gravel over long periods. This is due to two effects. In pressurized conditions, helicoidal vertical currents developing at the downstream extremities of the trap and turbulent velocity fluctuations extract the gravel from the trap. In addition, during gallery dewatering (for maintenance and inspection), temporary free surface flow can transport gravel downstream of the trap. Non-structural solutions to the problem have been identified, optimized and validated on the scale model. They consist in creating above the traps a pseudo-bottom aligned with the gallery invert, using horizontal bars placed transversally to the flow, and in compartmenting the traps with vertical walls. The paper presents in detail the physical model and all the tests and measurements performed to quantify the problem and assess the efficiency of the modification solutions.

description: Beaches in India and elsewhere are getting destroyed at an alarming rate as many small ports are being built and sea walls are coming up on the banks. There is an urgent need to stop it. In 1966, Posey used cylinders of net filled with rock (called rock sausages) underlain by a reverse gravel filter for safety against scour in hydraulic structures. Pillai used a bed of stones enclosed in nets underlain by a reverse filter to allow overflow over a sand embankment. Later it was understood that a Polypropylene Fabric (P.F.) could be effective as a filter, and a bed of polypropylene bag filled with sand (like geo-tubes) can be used to prevent scour. However, the P.F. get weathered when exposed to sunlight. A breakthrough came when porous concrete blocks with high porosity, high strength and seawater resistance were developed and were used underlined by a P.F. An attempt was made in an experimental study on the Cheriathura Beach at Trivandrum. Porous concrete blocks 0.5 m X 0.5m, 10 cm thick were cast and arranged at a time of low tide, covering an area of 10 m x 5 m (with the P.F. underneath). When the waves acted frontally during high tide, this rode smoothly on the pavement, had their run-up, and later receded without displacing the slabs. This showed that porous concrete slabs could be a good armour for protecting the beach. The side slabs got displaced with lateral waves because no sidewall could be provided in the narrow strip of protection. It is felt that the porous concrete slabs can be placed deep in the beach so that during the erosive phase, the slab could function as armour, and when there is accretion, there would be deposition of sand on the slabs maintaining the beach.

description: As water demand is steadily increasing worldwide, it is very important to measure the discharge accurately for sustainable water resources management such as flood control, water distribution, hydraulic structures design, and hydro-environment management. Since decades the cup and propeller type current meters are used for the measurement of stream velocity, but due to emergent technology, Electromagnetic, Acoustic Doppler Current Profiler (ADCP), etc. are used for measuring the stream flows. These instruments have higher edge in accuracy, consistency, and reliability. Quantitative information on performance and validation in the field of discharge measurement is rare. Hence performance testing of such instrument is essential prior to conducting measurements in fields. The objective of the study is to ascertain the accuracy in velocity measurement of these instruments with the standards. The ADCP transmits a constant high frequency sound wave into the water that ricochets off particles suspended in the moving water and reflect back to the instrument with a slightly lowered frequency due to the Doppler Effect. The performance testing of these sophisticated instruments is done in the straight open channel by Current Meter Rating Trolley. The ADCP deployed on the trolley will be towed at a predefined speed of the Rating Trolley and the corresponding velocity indicated by the sensor will establish the relation. This indicates the performance of the ADCP and its appropriate working in terms of accuracy.

description: $Q$-systems and $T$-systems are systems of integrable difference equations that have recently attracted much attention, and have wide applications in representation theory and statistical mechanics. We show that certain $τ$-functions, given as matrix elements of the action of the loop group of ${\rm GL}_{2}$ on two-component fermionic Fock space, give solutions of a $Q$-system. An obvious generalization using the loop group of ${\rm GL}_3$ acting on three-component fermionic Fock space leads to a new system of 4 difference equations.
