Void Capital
Creators: name: Stathatos, Iason
Publisher: name: SPOOL
Year: 2018

description: Void Capital provides a template, an open source architectural blueprint for urban densification. The city naturally demolishes and preserves its built forms, to achieve a dense dynamic city. However, in the name of ‘history’, or ‘quality’, this natural re-actualisation process is discontinued. Void Capital reintroduces the historic centre of the European metropolis as City of Perpetual Modernity. Its tools are typologies of the city’s periphery, combined to create ever-new architectural arrangements. Implemented in Paris, the project renegotiates the typologies of the Grand Ensemble (the Housing District) and the Quartier d’Affaires (the Business District), both once positive icons of modernity, now fallen into despair.

description: The processing of quantum information always has a cost in terms of physical resources such as energy or time. Determining the resource requirements is not only an indispensable step in the design of practical devices - the resources need to be actually provided - but may also yield fundamental constraints on the class of processes that are physically possible. Here we study how much energy is required to implement a desired unitary gate on a quantum system with a non-trivial energy spectrum. We derive a general lower bound on the energy requirement, extending the main result of Ref. [1] from finite dimensional systems to systems with unbounded Hamiltonians. Such an extension has immediate applications in quantum information processing with optical systems, and allows us to provide bounds on the energy requirement of continuous variable quantum gates, such as displacement and squeezing gates.

description: Double Face 2.0 is a novel solar wall, joining a strong design identity and high technical performances. In response to the need for energy saving, new high-performance building elements are shape-optimised for passive climate design and to increase user engagement. Given a design concept, computational approaches help to optimise and to customise high-performance building elements for any environment. Double Face 2.0 has been developed by research through design involving designing, 3D modelling, robotic FDM printing, prototyping, experimenting, simulating, and simulation-based optimising. An adjustable, lightweight, translucent Trombe wall has been developed, using an insulator (aerogel) and heat storage (phase change material) encapsulated in optimised and customizable shapes. In winter, it captures, stores, and re-radiates heat from the sun (heating); in summer, it captures internal heat (cooling).

description: Egocity and Wegocity are based on the hypothesis of maximum density achievement and maximum desire fulfilment when designing collective housing. This intensity, when applied to housing, can optimise land use, help combat inequality, and counteract the centrifugal force condemning contemporary urban development to urban sprawl. We asked students to tackle the challenge of converting density into desire by accommodating the users’ needs, yet following a restricted urban envelope that keeps energy consumption and carbon footprint under control. Students developed an innovative game capable of facilitating and visualising a typological puzzle resulting when different clients, cultures, and desires come to live together. Users began to work with and around each other and, somehow, together create something that is even nicer.

description: We investigate the dependence of the structural phase transitions in an infinite quasi-one-dimensional system of repulsively interacting particles on the profile of the confining channel. Three different functional expressions for the confinement potential related to real experimental systems are used that can be tuned continuously from a parabolic to a hard-wall potential in order to find a thorough understanding of the ordering of the chain-like structure transitions. We resolve the longstanding issue why the most theories predicted a 1-2-4-3-4 sequence of chain configurations with increasing density, while some experiments found the 1-2-3-4 sequence.

description: We study the three-dimensional structure of the Milky Way using 65,981 Mira variable stars discovered by the Optical Gravitational Lensing Experiment (OGLE) survey. The spatial distribution of the Mira stars is analyzed with a model containing three barred components that include the X-shaped boxy component in the Galactic center (GC), and an axisymmetric disk. We take into account the distance uncertainties by implementing the Bayesian hierarchical inference method. The distance to the GC is $R_0 = 7.66 \pm 0.01 \mathrm{(stat.)} \pm 0.39 \mathrm{(sys.)}$ kpc, while the inclination of the major axis of the bulge to the Sun-GC line-of-sight is $θ= 20.2^\circ \pm 0.6^\circ \mathrm{(stat.)} \pm 0.7^\circ \mathrm{(sys.)} $. We present, for the first time, a detailed three-dimensional map of the Milky Way composed of young and intermediate-age stellar populations. Our analysis provides independent evidence for both the X-shaped bulge component and the flaring disk (being plausibly warped). We provide the complete dataset of properties of Miras that were used for calculations in this work. The table includes: mean brightness and amplitudes in nine photometric bands (covering a range of wavelength from 0.5 to 12 $μ$m), photometric chemical type, estimated extinction, and calculated distance with its uncertainty for each Mira variable. The median distance accuracy to a Mira star is at the level of $6.6\%$.

Year: 2018

description: The research shows experiences of the war in Sarajevo from the citizens’ point of view, learned from architectural drawings, videos, photos, and other media projects from the war, different from sensational media representations. The results display how citizens in Sarajevo have been responding to the military violence during the siege between 1992-1996, relying on all available architectural and other materials. The newly developed x-media analysis includes the study of analogue and digital media documents on the war in Sarajevo, and a translation of the analogue materials to the digital materials for exhibitions or lectures. A virtual reality model includes a 3D model of the city and a transformed by war modernist apartment. Archival photos and videos from the war are collected in the open source digital archive ‘un-war space’.

description: Con la fine del secondo conflitto mondiale si aprì una nuova pagina sociale ed economica della storia della Basilicata. Le principali forze politiche, in piena fase riorganizzativa, si trovarono a fare i conti con una realtà che, se da un lato manteneva quasi intatti gli storici assetti economici e sociali – ad eccezione di un profondo processo di «destrutturazione sociale», generato da una consistente emorragia migratoria – dall’altro dimostrava una forte tensione al cambiamento, che diffusa soprattutto nel mondo rurale, si manifestava attraverso le agitazioni e gli scioperi bracciantili. I dati statistici forniti dal Censimento Generale dell’Industria e del Commercio del 1951 e i risultati dall’Inchiesta parlamentare sulla miseria del 1953 fotografarono la situazione economica e sociale della Basilicata. Nel corso del censimento furono rilevate sul territorio regionale 18.183 unità produttive locali per un totale di 38.334 addetti. Prevalevano il settore alimentare (1.650 imprese e 3.954 addetti), il tessile (3.580 imprese e 4. 820 addetti) e quello del legno (1.948 imprese e 3.043 addetti). Segni evidenti del carattere artigianale del sistema produttivo lucano erano il basso numero di addetti, la conduzione familiare delle imprese ed un rapporto molto basso tra unità la conduzione familiare delle imprese ed un rapporto molto basso tra unità produttive e numero di addetti. Quasi inesistenti, inoltre, erano i settori produttivi capital intensive. Nel corso dell’inchiesta sulla miseria dell’onorevole Gaetano Ambrico, la provincia materana venne definita la «più povera di industrie fra le province italiane». Casillo, presidente della Camera di Commercio, audito dalla Commissione parlamentare, affermò che l’industria nella provincia di Matera era pressoché inesistente e «quel poco» che c’era e che assumeva il «nome di industria» interessava pochissime addetti. In regione mancavano le condizioni infrastrutturali minime per avviare uno sviluppo industriale. La provincia di Matera era servita solo da 97 chilometri di strada ferrata, con un indice di dotazione ferroviaria del 2,7% a fronte del 7,4% della media nazionale ed un indice di dotazione stradale del 22,8% contro il 58,6% nazionale. In tali condizioni solo un programma di investimenti statali avrebbe potuto avviare una fase di sviluppo economico e produttivo della provincia e più in generale della regione. ..

description: Co-clustering is a data mining technique used to extract the underlying block structure between the rows and columns of a data matrix. Many approaches have been studied and have shown their capacity to extract such structures in continuous, binary or contingency tables. However, very little work has been done to perform co-clustering on mixed type data. In this article, we extend the latent block models based co-clustering to the case of mixed data (continuous and binary variables). We then evaluate the effectiveness of the proposed approach on simulated data and we discuss its advantages and potential limits.

description: The evolution of powerful extragalactic jets is not only interesting by itself, but also for its impact on the evolution of the host galaxy and its surroundings. We have performed long-term axisymmetric numerical simulations of relativistic jets with different powers to study their evolution through an environment with a pressure and density gradient. Our results show key differences in the evolution of jets with different powers in terms of the spatial and temporal scales of energy deposition. According to our results, the observed morphology in X-ray cavities requires that an important fraction of the jet's energetic budget is in the form of internal energy. Thus, light, lepton-dominated jets are favoured. In all cases, heating is mainly produced by shocks. Cavity overpressure is sustained by an important population of thermal particles. Our simulations reproduce the cool-core structure in projected, luminosity-weighted temperature. We have performed an additional simulation of a slow, massive jet and discuss the differences with its relativistic counterparts. Important qualitative and quantitative differences are found between the non-relativistic and the relativistic jets. Our conclusions point towards a dual-mode of AGN kinetic feedback, depending on the jet power.

description: We electrically measure intrinsic silicon quantum dots with electrostatically defined tunnel barriers. The presence of both p-type and n-type ohmic contacts enables the accumulation of either electrons or holes. Thus we are able to study both transport regimes within the same device. We investigate the effect of the tunnel barriers and the electrostatically defined quantum dots. There is greater localisation of charge states under the tunnel barriers in the case of hole conduction leading to higher charge noise in the p-regime.

description: Fe-based superconductors were discovered in 2008. This discovery with T$_c$ values up to 56 K, generated a new belief in the field of superconductivity. Till its discovery, high temperature superconductivity in cuprates, created a prejudice that Cu-oxides are essential building blocks for a high temperature superconducting material. These Fe based superconductors do not contain Cu-O planes (some of the materials are even O free). It will be argued in this review, that these iron pnictide and chalcogenide (FePn/Ch) superconductors have Fe electrons at the Fermi surface together with an unusual Fermiology that can change rapidly with doping. This may lead to very different normal and superconducting state properties compared to those in standard electron-phonon coupled {\it conventional} superconductors. There are a large number of evidences showing that superconductivity, magnetism, orbital fluctuations are intimately related and coexist in these materials although the mechanism of superconductivity in these compounds is still unknown. The electronic specific heat, $\frac{2Δ}{k_B T_c}$ ratio, phase diagrams, isotope effect, crystal structures and there correlation to T$_c$ from various available experimental data are main inputs of this review to show the above.

description: The Monge-Kantorovich mass-transportation problem has been shown to be fundamental for various basic problems in analysis and geometry in recent years. Shen and Zheng (2010) proposed a probability method to transform the celebrated Monge-Kantorovich problem in a bounded region of the Euclidean plane into a Dirichlet boundary problem associated to a nonlinear elliptic equation. Their results are original and sound, however, their arguments leading to the main results are skipped and difficult to follow. In the present paper, we adopt a different approach and give a short and easy-followed detailed proof for their main results.

description: The form method as popularised by Lions and Kato is a successful device to associate m-sectorial operators with suitable elliptic or sectorial forms. McIntosh generalised the form method to an accretive setting, thereby allowing to associate m-accretive operators with suitable accretive forms. Classically, the form domain is required to be densely embedded into the Hilbert space. Recently, this requirement was relaxed by Arendt and ter Elst in the setting of elliptic and sectorial forms. Here we study the prospects of a generalised form method for accretive forms to generate accretive operators. In particular, we work with the same relaxed condition on the form domain as used by Arendt and ter Elst. We give a multitude of examples for many degenerate phenomena that can occur in the most general setting. We characterise when the associated operator is m-accretive and investigate the class of operators that can be generated. For the case that the associated operator is m-accretive, we study form approximation and Ouhabaz type invariance criteria.

description: Co-clustering is a class of unsupervised data analysis techniques that extract the existing underlying dependency structure between the instances and variables of a data table as homogeneous blocks. Most of those techniques are limited to variables of the same type. In this paper, we propose a mixed data co-clustering method based on a two-step methodology. In the first step, all the variables are binarized according to a number of bins chosen by the analyst, by equal frequency discretization in the numerical case, or keeping the most frequent values in the categorical case. The second step applies a co-clustering to the instances and the binary variables, leading to groups of instances and groups of variable parts. We apply this methodology on several data sets and compare with the results of a Multiple Correspondence Analysis applied to the same data.

description: Monumental buildings are demolished when they lose their traditional function. These historical monuments can be maintained by repurposing them for modern use, like lectures and musical events. This results in a demand for different acoustic conditions. However, monuments are subject to strict building intervention regulations; any intervention concerning changes to the original elements are often prohibited. This creates a demand for demountable and adaptable product design, repurposing monumental buildings by alleviating acoustical problems without distorting the view towards the monumental elements. This research focused on developing sound absorption panels based on the micro-perforation principle: manufacturing these in thin glass panels, evaluating their influence on strength and transparency, optimizing sound absorption (perforation diameter and ratio) using a tailor-made computational model, and creating a pattern of perforations that optimizes strength.

description: The red MSX source G034.5964-01.0292 (MSXG34), catalogued as a massive YSO, was observed in molecular lines with the aim of discover and study molecular outflows. We mapped a region of 3'x3' centered at MSXG34 using the Atacama Submillimeter Telescope Experiment in the 12CO J=3-2 and HCO+ J=4-3 lines with an angular and spectral resolution of 22" and 0.11 km/s, respectively. Additionally, public 13CO J=1-0 and near-IR UKIDSS data obtained from the Galactic Ring Survey and the WFCAM Sciencie Archive, respectively, were analyzed. We found that the 12CO spectra towards the YSO present a self-absorption dip, as it is usual in star forming regions, and spectral wings evidencing outflow activity. The HCO+ was detected only towards the MSXG34 position at v_LSR ~ 14.2 km/s, in coincidence with the 12CO absorption dip and approximately with the velocity of previous ammonia observations. HCO+ and NH3 are known to be enhanced in molecular outflows. Analyzing the spectral wings of the 12CO line, we discovered misaligned red- and blue-shifted molecular outflows associated with MSXG34. The near-IR emission shows a cone-like shape nebulosity composed by two arc-like features related to the YSO, which can be due to a cavity cleared in the circumstellar material by a precessing jet. This can explain the misalignment in the molecular outflows. From the analysis of the 13CO J=1--0 data we suggest that the YSO is very likely related to a molecular clump ranging between 10 and 14 km/s. This suggests that MSXG34, with an associated central velocity of about 14 km/s, may be located in the background of this clump. Thus, the blue-shifted outflow is probably deflected by the interaction with dense gas along the line of sight.

description: Our electricity is predominantly powered by alternating current (AC), ever since the War of Currents ended in the favor of Nicola Tesla at the end of the 19th century. However, lots of the appliances we use, such as electronics and lights with light-emitting diode (LED) technology, work internally on direct current (DC) and it is projected that the number of these appliances will increase in the near future. Another contributor to the increase in DC consumption is the ongoing electrification of mobility (Electric Vehicles (EVs)). At the same time, photovoltaics (PV) generate DC voltages, while the most common storage technologies also use DC. In order to integrate all these appliances and technologies to the existing AC grid, there is a need for converters which introduce power losses. By distributing DC power to DC devices instead of converting it to AC first, it is possible to avoid substantial energy losses that occur every time electricity is converted. This situation initiated the concept for the implementation of the DC-Flexhouse project. A prototype DC installation will be developed and tested in one of the buildings of the developing living lab area called the District of Tomorrow (De Wijk van Morgen) which is located in Heerlen, the Netherlands. A neighborhood cooperative (Vrieheide cooperatie) is also part of the consortium in order to address the aspect of social acceptance. Although DC seems to be a promising solution for a more sustainable energy system, the business case is still debatable due to both technology- and market-related challenges. The current energy infrastructure is predominantly based on AC, manufacturers produce devices based on AC standards and people are using many AC products across a long life span. This Smart Energy Buildings & Cities (SEB&C) PDEng project is a contribution to the DC-Flexhouse project. The aim is to analyze the challenges in the transition to DC micro grids, assess the market potential of DC applications in the built environment and develop a framework that leads to a commercial success.

description: The behaviors of resistance, magnetoresistance (up to 5 T), and Hall electromotive force (EMF) with varying temperature (from 10 to 300 K) and measuring current (from 10 mkA to 10 mA) are studied for the Si sample with CrSi2 nanocrystallites (NC) in the plane (111). The conduction in such heterostructure proceeds in the plane with the NC and is the conduction of a two-dimensional system of charge carriers that shows some unusual effects. The temperature variation of resistivitymaybe treated as the result of the effect of thermal activation but in this case it is characterized by a low activation energy different in value in different temperature ranges. This suggests that the mechanism of conduction is more complex. It is found that the conduction is determined by the effect of temperature variation not only on carrier concentration but also on its mobility. Magnetoresistivity is also of different shape in different temperature ranges. All the above features are treated in terms of the proposed model of electron hopping through the conduction band (or hole hopping through the valence band). A peculiar effect of giant reduction in resistivity with increasing the measuring current has been revealed. Discussed are some possible factors responsible for this effect.

description: In recent years the applications of machine learning models have increased rapidly, due to the large amount of available data and technological progress.While some domains like web analysis can benefit from this with only minor restrictions, other fields like in medicine with patient data are strongerregulated. In particular \emph{data privacy} plays an important role as recently highlighted by the trustworthy AI initiative of the EU or general privacy regulations in legislation. Another major challenge is, that the required training \emph{data is} often \emph{distributed} in terms of features or samples and unavailable for classicalbatch learning approaches. In 2016 Google came up with a framework, called \emph{Federated Learning} to solve both of these problems. We provide a brief overview on existing Methods and Applications in the field of vertical and horizontal \emph{Federated Learning}, as well as \emph{Fderated Transfer Learning}.

description: Notre travail de Bachelor porte sur la thématique de la prévention du tabac chez les adolescents. Le taux de jeunes fumeurs entre 15 et 21 ans s’élève à 24 %, cependant 87% des fumeurs adultes ont commencé avant l’âge de 21 ans. (Gmel et al., 2016). A travers les résultats obtenus, nous avons pu mettre en évidence cinq thématiques principales qui nous permettent d'apporter des réponses à notre problématique. En effet, la volonté et la motivation, l’influence de l’environnement, l’influence du stress, les stratégies de coping ainsi que le processus de changement de comportement sont des éléments essentiels dans la prévention secondaire du tabac chez les adolescents.

description: Bedrijven gaan tegenwoordig vooral lineair om met hun materialen. Grondstoffen komen binnen, worden verwerkt tot producten en hun afval wordt afgevoerd. Binnen één bedrijf ziet dit er logisch uit, maar in een systeem van meerdere bedrijven is te zien dat dit efficiënter kan. Als het afval van een bedrijf gebruikt zou worden als grondstof door een ander bedrijf, ontstaat er industriële symbiose. Daardoor worden er minder grondstoffen verbruikt en worden bruikbare restmaterialen niet verspild. Om bedrijven te helpen bij het zoeken naar partners voor zulke uitwisselingen, is de software InduSym ontwikkeld. Met de software kunnen bedrijven hun grondstoffen en restmateriaal invoeren in een database. Een algoritme doorzoekt deze database en presenteert in een rapport de kansen om te komen tot een symbiotische uitwisseling van reststromen.

description: The water tower of Schimmert was built in 1926 to cover the needs of water of Schimmert and the surrounding areas as well. This imposing 38 meters high tower dwarfs any nearby buildings, providing a 360° view of the surrounding area and deserves its pseudonym de Reus van Schimmert (the Giant of Schimmert). In the attempt to find a sustainable business model for the iconic building the concept of installing a data center in its core is investigated. The waste heat from the servers will be transferred to the reservoir on the top and from there used to power a district heating system in Schimmert.

description: We consider almost-primes of the form $f(p)$ where $f$ is an irreducible polynomial over $\mathbb Z$ and $p$ runs over primes. We improve a result of Richert for polynomials of degree at least $3$. In particular we show that, when the degree is large, there are infinitely many primes $p$ for which $f(p)$ has at most $°f+O(\log°f)$ prime factors.

Unleash the building bots: 3d printing structures with an autonomous robot swarm

description: 3D printing techniques for the building industry are developing fast. Concepts like Contour printing, concrete printing concepts of the TU/E and D Shape are examples. Despite the range of techniques is broad (and vary from a large gantry system, to a supersized Delta printer for example), many of the developed 3D printing machines are constraint in their movement. Mobile 3D printers however show advantages in flexibility, as they can move outside the constraint of a large 3D printer and they can move in the highly unstructured and hazardous environment of the building site, which can be dangerous for people to work in. The Institute for advanced architecture of Catalonia developed vehicles, which they call minibuilders, each designed for a special task in the building process, printing the foundation, printing a wall, smoothing the outer-wall etc. The minibuilders are used in succession according the building process. However they are still limited in their autonomy and capability. The minibuilders are tethered with a hose to a vehicle, which carries the concrete supply.

description: Car traffic causes carbon emissions and air pollution and has negative effects on public health and quality of life in cities. Solar bikes are an innovative, sustainable transport option that can offer a substitute for car travel. Solar bikes are electric bikes with solar cells that are powered by the sun. This expands their range compared to regular e-bikes as the bikes are charged during the trip and at the destination without electricity. The aim of this project is to understand people’s preferences, conditions for acceptance and experiences with the solar bike. Insight in preferences and experiences will assist urban policy makers in identifying which interventions in the built environment can stimulate the acceptance and use of solar bikes.
