The Architecture of Logistics

description: The ambition of Footprint 23 is to provide a critical survey of the architecture of logistics, unfolding the multivalences of its apparatus, dissecting its buildings and spaces, its technologies and labour relations, its historical evolutions as well as its future projections. Gathering academic papers and visual essays from researchers and emerging scholars in the field, the issue follows three main directions of inquiry. The first trajectory attempts to define what logistics is and how it operates, focusing on the inherent ambivalence of its apparatus, able to cope with different scales and various temporal dimensions – from barcodes and gadgets to global routes and territorial infrastructures – constituting both a physical and abstract framework supporting, measuring and quantifying movements and actions, thoughts and desires. The second trajectory investigates the way logistics penetrates our existences, not simply by affecting how we live and work but the way in which it provides the very possibility of life as such, or, in other words, how logistics is inherently political. The third trajectory tackles the past, present and future of logistics, considered as the most crucial apparatus determining the human impact on the earth, controlling the distribution and organisation of organisms and ecosystems, triggering new and more violent forms of colonisation and exploitation. This issue of Footprint does not seek definitive statements or hypothetic solutions for the monstrous nature of logistics. On the opposite, it aims at unfolding its inner contradictions to propose new possibilities of exploration for an architecture and its project.

title: Effect of Deficient Tailwater on the Performance of Slotted Roller Bucket of Indira Sagar Dam, Madhya Pradesh

description: Slotted roller bucket type energy dissipators are provided for spillways when the tailwater depth is 1.2 times the sequent depth required for the formation of a hydraulic jump. In slotted roller buckets, the dissipation of energy occurs by the lateral spreading of jet passing through bucket slots in addition to the formation of two complementary rollers as in the solid bucket. These are provided for spillways where the downstream river bed is of sound rock. However, when the tailwater levels are not realised during the release of floods over the spillway and surface and ground rollers are not formed, it results in a possible sweep of the flood out of the bucket. Deficient tailwater levels during the initial period of operation of the bucket leading to ski action, generation of high hydrodynamic pressures during roller formation due to very high incoming velocities and occurrence of negative pressures on the bucket teeth, are some of the hydraulic parameters that lead to damage to the slotted roller bucket. Indira Sagar Dam is 653 m long and 92 m in height and was built on the River Narmada in Madhya Pradesh. The main and auxiliary spillway comprises 12 and 8 spans respectively of size each 20 m x 17 m and is designed to dispose of a Probable Maximum Flood of  83,400 m3/s. The energy dissipator provided was original in the form of a  slotted roller bucket. The project is in operation from 2004-2005. Discharges of the magnitude 30,000 m3/s were released during the monsoon of 2013 and then it was observed that the entire slotted roller bucket in front of spans 6 to 12 was washed away. The teeth of the roller bucket were overturned and thrown away by the flood waters. Theoretical analysis for actual discharges passed over the spillway from 2006 to 2012 indicated that the roller action was not forming for these conditions and instead ski action was taking place due to deficient tailwater levels. There was also a transition from ski action to roller action for increasing discharges till the tailwater build was realised. In fact, this is the inherent shortcoming of roller bucket type of energy dissipators and damages to the bucket have been reported elsewhere also. In this paper, the authors account for the causes that damaged the slotted roller bucket of Indira Sagar dam, M.P and recommendations suggested for improving the performance of energy dissipation arrangement.
The Nation’s ‘Other’ Housing Project

description: Singapore’s privatised high-rise housing landscape is the nation’s ‘other’ housing project, emerging alongside the city-state’s dominant narrative of its successful public housing project since the 1970s. Unique to Singapore’s privatised high-rise housing developments was the intervention of the state in the close regulation of scarce land. Singapore’s private high-rise housing developments thus reflect a nation’s attitude towards its land as resource, and its subsequent imaginations and productions of more ‘land’ in the construction of high-rise housing estates. State intervention also maximised these housing developments as part of wider national aspirations to the status of a global city, and for its citizens, a ‘green and gracious’ Singaporean society. Taking the Pearlbank Apartments and the Pandan Valley Condominium as two key developments of Singapore’s emerging private high-rise housing landscape in the 1970s, this article examines the production of the nation’s aspirational housing in the confluence of Singaporean state-led vision and a people’s housing aspirations.

description: Die Arbeit ist mit den ökonomischen Auswirkungen von Regulierungen, die für die deutsche Filmwirtschaft relevant sind, befasst. Es werden die ökonomischen Effekte dreier Regulierungsfelder, die in der öffentlichen Debatte diskutiert werden, betrachtet. Diese sind: Das deutsche Filmförderungsgesetz (FFG), das Urheberrechtsgesetz (UrhG) und der Rundfunkstaatsvertrag (RStV). Im Zentrum der Analyse steht die Frage, wie die jeweiligen Regulierungen die ökonomische Effizienz beeinflussen. Darüber hinaus werden wesentliche institutionelle und marktliche Charakteristika der deutschen Filmwirtschaft betrachtet. Teile der Untersuchung sind in eine breit angelegte Regressionsanalyse über die Determinanten des Erfolges deutscher Kinofilme eingebettet. Die Arbeit zeigt, dass die betrachteten Regulierungen im Allgemeinen negative Auswirkungen auf die ökonomische Effizienz haben.
description: This work deals with the economic impact of regulations on the German film industry, focusing in particular on the effects of three pieces of legislation central to Germany's public debate on film politics. The legislation considered is the Film Act (Filmförderungsgesetz - FFG), the amendments to the Copyright Law (Urheberrechtsgesetz - UrhG), and the Inter-State Agreement on Broadcasting (Rundfunkstaatsvertrag - RStV). The inquiry examines how these statutes affect economic efficiency. In addition, major market and institutional characteristics of the German motion picture industry are studied. The analysis is partly embedded in a broadly disposed regression analysis of the determinants of performance of German movies in the theatrical market. The work indicates that the regulations considered generally detract from economic efficiency.

description: An effective potential is created for the dynamics of a test particle, which preserves dilatation symmetry for nonlinear static dilaton-Maxwell background. It is found that the central interaction in this theory is regular everywhere, and that the theory is asymptotically free at short distances and that it has a Coulomb properties at great distances from the source. It is shown that static and spherically symmetric source, behaves like a soliton: it has the finite energy characteristics that are inversely proportional to the dilaton-Maxwell coupling constant.

Publisher: name: Utah State University

description: In the past two decades, increasing numbers of piano key weirs (PKW) have been constructed due to their sufficient hydraulic performance and optimized space requirements. Extensive experiments and numerical studies have been carried out to identify the optimal geometry and maximize the discharge capacity. However, less attention has been paid to address energy dissipation processes and the flow structure downstream, especially for in-channel applications. Within the present study, symmetrical trapezoidal piano key weir models were fabricated in two model sizes with different cycle numbers via a 3D printing technique. Both models were tested under equivalent hydraulic conditions to investigate the potential influence of the cycle number and model size regarding energy dissipation processes and the flow structure downstream of the weir. Data show identical downstream residual energy for both investigated weirs, indicating that a model with 30 cm weir height and single cycle is able to deliver reasonable results in terms of total energy dissipation. However, the flow structure downstream of the weir was observed to differ with actual weir size and cycle number, indicating that small-scaled models with an insufficient cycle number may not be able to represent a similar outflow characteristic as the prototype. Sufficient cycle number was found to be beneficial for a more stable downstream flow condition. To facilitate practical design of geometrically similar weirs, observational insights of downstream flow condition development have been provided and analytical equations have been proposed for localization of aerated flow region as well as residual energy estimation.

description: Cedric Price’s architecture approaches time and space atypically, focusing primarily on the needs and desires of the user. His ‘short-life’ housing system, designed in 1970–1972 in response to a national crisis of housing provision, takes consumer choice as the organising principle of its design. Its formal flexibility blurs the separation between the house and workplace, while its customisability and disposability reduces the family home to an expendable commodity. The short-life house accommodates a lifestyle of precarity characteristic of neoliberal society, aligning with neoliberal discourses on society emergent in Britain at the beginning of the 1970s.

Publisher: name: FOOTPRINT
Year: 2019

description: The house, having always been the locus of socio-political struggles of Tehrani citizens, after the Iran-Iraq war gradually came to materialise many more complex issues. It became a space and a structure embodying the state’s subjugating agenda, forces of the housing market, its labour and material market, the desires of the people, their political action, and architectural practitioners’ attempts to prove relevant. This visual essay focuses on three threads in Tehran in housing in the the post-Iran-Iraq-war context: the liberalising procedures and regulatory frameworks that still constitute the most common form of housing, positing middle class citizens as the main players in the market; the architectural repercussions of the regulating mechanisms and the subsequent formation of a homogenised form of housing; and a reading of these forms of housing as sites of people’s practices of resistance in a framework of constant re-appropriation.

description: Over the last three decades Josep Maria Montaner played a key role as an educator in the prestigious Barcelona School of Architecture. Together with Zaida Muxí he initiated the Housing Laboratory of the Twenty-First Century, an advanced master’s programme held at that institution for more than a decade. In 2015, Montaner moved from the world of academia to politics, starting his tenure as housing councillor in the cabinet of Ada Colau, herself a housing activist who became mayor of Barcelona. In this interview, conducted by David H. Falagán, Montaner highlights the crucial importance of aligning housing policies, housing design, and citizens’ participation as a strategy to combat the housing crisis triggered by the dominant neoliberal system.

description: The Schrödinger equation of the spherical symmetry quantum models such as the hydrogen atom problem seems to be analytically non-solvable in higher dimensions. When we try to compactifying one or several dimensions this question can maybe solved. This paper stands for the study of the spherical symmetry quantum models on noncommutative spacetime with compactified extra dimensions. We provide analytically the resulting spectrum of the hydrogen atom and Yukawa problem in $4+1$ dimensional noncommutative spacetime in the first order approximation of noncommutative parameter. The case of higher dimensions $D\geq 4$ is also discussed.

There is no Such Thing as a Free Market
Creators: name: Van Den Heuvel, Dirk
Publisher: name: FOOTPRINT
Year: 2019

description: To deconstruct the still hegemonic narrative of free market ideologists in the realm of housing, this article looks at the provocative position of the German-British architect Patrik Schumacher, director of Zaha Hadid Architects. Schumacher’s 2016 lecture on housing at the World Architecture Festival in Berlin, in which he claims that only wholesale privatisation of urbanism would solve the housing crisis, is scrutinised on the two interrelated concepts of the free market and state intervention. Schumacher’s lecture is analysed within the context of the current housing crisis in the United Kingdom and London in particular, which dates back to the years of the Tory government of Margaret Thatcher. Additionally, the aftermath of the banking and credit crisis of 2008 brought the further breakdown of welfare state arrangements under the politics of so-called austerity. Lastly, the housing situation worsened due to the disruptive rise of the creative classes as depicted by urban sociologist Richard Florida. Schumacher’s position is interpreted in the tradition of the ideas of philosopher Ayn Rand and Nietzschean master-servant morality. A connection with the ideas of Rem Koolhaas is identified, in particular those expounded in his book Delirious New York and with Koolhaas’ conception of the architect as a surfer as well as a hostage, who is at the mercy of larger forces he cannot control. The argument is concluded by referencing a number of renowned alternatives to a delusional free market approach to solve the housing crisis, namely social housing projects from continental Europe. Ultimately, the importance of striking a balance between private opportunity and public planning is emphasised.

description: Let L be a finite dimensional Lie algebra over an algebraically closed field k of characteristic zero. We provide necessary and also some sufficient conditions in order for its Poisson center and semi-center to be polynomial algebras over k. This occurs for instance if L is quadratic of index 2 with L not equal to [L,L] and also if L is nilpotent of index at most 2. The converse holds for filiform Lie algebras of type Ln, Qn, Rn and Wn. We also show how Dixmier's fourth problem for an algebraic Lie algebra L can be reduced to that of its canonical truncation. Moreover, Dixmier's statement holds for all Lie algebras of dimension at most eight. The nonsolvable, indecomposable ones among them possess a polynomial Poisson center and semi-center.
description: 59 pages. The statement of Proposition 40 is more accurate and its proof is more detailed. Theorem 52 has been extended to quadratic nilpotent Lie algebras of index 3. The statement of Theorem 53 needs the extra condition that the Lie algebra L is indecomposable

description: Block ramps are ecofriendly drop structures, which ensure stable downstream river bed, peculiar to flows over macro roughness elements. It uniquely serves an essential paradigm in riverine management, to encounter deliveries in an ecologically sound manner. It permits safe fish passage, stabilizes stream banks and bed profiles and creates habitat diversity. Study of flows over block ramps are quite extensive and are associated with many intricacies. In this paper, flume experiments were conducted in the hydraulic laboratory of National Institute of Technology Patna. The particle densimetric Froude number (F*) was calculated for the mobile bed and chosen to predict the hydraulic conditions for incipient sediment motion in the uniform beds and it is compared with the established literature formulations to estimate the stability of the beds under large-scale roughness conditions. Scour volumes from each experimental run is quantified and the intensity of sediment motion was determined.  Experimental data analysis allowed describing the mechanism of incipient motion of the mobile bed in the stilling basin, energy dissipation, flow resistance and in the interstitial flow over rock ramps and intensity of block movement for various flow regimes. It was found that the dimensionless shields stress increases with ramp slope and the intensity of ramp motion decreases with the shear stress. The results indicated that friction resistance increases with relative submergence for the tested range of experiments. A comparison with previous literature with uniform sediment transport indicates that relative roughness of block is responsible for increasing the dimensionless Shields stress. The results of physical testing can be used to assess and predict the effective dissipation of energy and its impact on the stability of rock structures.

description: What can one do when the things and processes used to sustain oneself – physically, economically, emotionally – are executed at a scale and intensity whereby they become poisonous? Such a scenario describes certain addictions. An illustration of such an addiction on a planetary scale is exemplified by the neologism agrilogistics. This planned approach to the environment seeks to organise, divide, and manage the earth in order to increase the likelihood of human survival. From parasite-vulnerable monocrops to systemic biopolitical violence upon indigenous peoples, these conditions expose the dark and unwanted externalities to the logistical algorithm that we have only recently begun to understand as deeply intertwined with each other and within all life on the planet. What can art and design do to intervene in this positive feedback loop of economic growth and environmental catastrophe? Perhaps one thing we can do is to use visual, material, and spatial media to think the world differently by questioning the premise of anthropocentrism, establishing instead new conditions of relation between human and nonhuman and with it, new forms of kinship with other species. The exhibition Ambiguous Territory: Architecture, Landscape and the Postnatural assembles a shifting tide of practices, objects, and images by architects, landscape architects, and artists that points to ways of operating within this new paradigm.

description: First-order logic with dependent sorts, such as Makkai's first-order logic with dependent sorts (FOLDS), or Aczel's and Belo's dependently typed (intuitionistic) first-order logic (DFOL), may be regarded as logic enriched dependent type theories. Categories with families (cwfs) is an established semantical structure for dependent type theories, such as Martin-Löf type theory. We introduce in this article a notion of hyperdoctrine over a cwf, and show how FOLDS and DFOL fit in this semantical framework. A soundness and completeness theorem is proved for DFOL. The semantics is functorial in the sense of Lawvere, and uses a dependent version of the Lindenbaum-Tarski algebra for a DFOL theory. Agreement with standard first-order semantics is established. Applications of DFOL to constructive mathematics and categorical foundations are given. A key feature is a local propositions-as-types principle.

Divine Vengeance in Herodotus' Histories
Creators: name: Smolin, Nathan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This essay argues that the motifs of divine vengeance present in the Histories represent a conscious, considered theory of divine action in the world. This theory is the result of Herodotus’ empirical methodology, and is defined by an admitted lack of access to poetic revelation or other actual insight into the motivation and nature of divinity. Instead, Herodotus’ theory is based on his own analysis of historical events on a large scale. Divinity possesses a basically regulatory role in the cosmos, ensuring that history follows certain consistent patterns. One such pattern is vengeance, by which a large-scale balance of reciprocity is maintained in human events through acts of repayment carried out with the support of divinity. This theory underlies Herodotus’ historical project, reinforcing his general skepticism about human knowledge and power and making possible his universalizing approach to historical narrative.

description: Zero temperature non-plateau magnetization is a peculiar property of a quantum spin chain and it sometimes appears due to different gyromagnetic factors. In this study, we illustrate a quite unusual nonplateau magnetization property driven by XY-anisotropy in an Ising-XYZ diamond chain. Two particles with spin-1/2 are bonded by XYZ coupling and they are responsible for the emergence of non-plateau magnetization. These two quantum operator spins are bonded to two nodal Ising spins and this process is repeated infinitely to yield a diamond chain structure. Due to the non-plateau magnetization property, we focus our discussion on the magnetocaloric effect of this model by presenting the isentropic curves and the Gruneisen parameters, as well as showing the regions where the model exhibits an efficient magnetocaloric effect. Due to the existence of two phases located very close to each other, the strong XY-anisotropy exhibits a particular behavior with a magnetocaloric effect, with a wider interval in the magnetic field, where the magnetocaloric effect is efficient.

description: Hydraulic jumps are used as an energy dissipater, allowing excess energy from downstream flow to be dissipated through hydraulic structures, preventing scouring. Channel roughness is also necessary for good flow control, as it allows more excess energy to be dissipated downstream. To better understand the impact of channel roughness on dissipating energy in an open channel, this study investigates and compares the energy dissipation of hydraulic jumps based on roughened (gravel size 20mm) horizontal and sloping channel bed condition. The experiment was carried out in the Hydraulics Laboratory, Department of Civil Engineering, NIT Manipur (India) in a rectangular channel flume (16 m length, 0.6 m wide, and 0.8 m deep). The characteristics of hydraulic jumps (length of jump, upstream and downstream head, velocities, and subsequent depth ratio) were measured and using these characteristics, the amounts of energy dissipation are calculated. Results show that the sloping channel bed is much safer for the structure, dissipates more energy, and the control of the flow is much easier as compared to the horizontal condition. Thus, it can be suggested that sloping channel bed is an effective channel bed condition when energy dissipation is the main purpose. The experimental results were numerically simulated using CFD (Computational Fluid Dynamics) techniques and found to be within an acceptable range.

description: This essay proposes a reconstruction of the problem of logistics as seen through the prism of Gaza. Questioning the common approach of logistics strictly in terms of the flows that it releases and speeds up, it argues that the Gaza blockade itself constitutes a vast logistical operation. The essay proceeds by setting Gaza’s architecture of confinement against the ‘architecture of flow’ that typically characterises logistical sites around the world. By underlining the material connections between these, the essay calls for an approach of processes of restriction of mobility as a mirror image of the fast-tracking operations that logistics is primarily known for. On this basis, it proposes a notion of logistical power as a mode of power specifically exerted through the production of a differential regime of mobility.

description: We introduce the property of pre-expansivity for cellular automata (CA): it is the property of being expansive on asymptotic pairs of configurations (i.e. configurations that differ in only finitely many positions). Pre-expansivity therefore lies between expansivity and pre-injectivity, two important notions of CA theory. We show that there exist one-dimensional positively pre-expansive CAs which are not positively expansive and they can be chosen reversible (while positive expansivity is impossible for reversible CAs). We show however that no bi-dimensional CA which is linear over an Abelian group can be pre-expansive. We also consider the finer notion of k-expansivity (expansivity over pairs of configurations with exactly k differences) and show examples of linear CA in dimension 2 and on the free group that are k-expansive depending on the value of k, whereas no (positively) expansive CA exists in this setting.

description: High air entrainment to the hydraulic jump is one of the inherent aspects of this macroturbulent flow, extending its presence from the free surface to the bottom. Depending on the variety of fishes in this natural habitat, important values of supersaturation of total dissolved gases (TDG) could be reached immediately downstream of the energy dissipation structure, putting under risk the life of fishes. This article deals with the influence of deflectors designed to reduce TDG on the hydrodynamic behavior of energy dissipators of two important dams. The first one is Yacyretá dam (Paraná River, Argentina – Paraguay) where horizontal deflectors were installed after an environmental incident with important mortality of fishes due to supersaturation of TDG. The second case corresponds to Jorge Cepernic dam (Santa Cruz River, Argentina), which is currently under construction. Hydrodynamic evaluation of the stilling basins under initial design conditions and those derived from the installation of the deflectors was carried out by means of two-dimensional physical models of each of the mentioned projects. The analyses showed a decrease of the energy dissipation rate for Yacyretá energy dissipator, with a hydraulic jump length that exceeds the length of the stilling basin, aspects that demand a continuous supervision of the works. On the other hand, the evaluation carried out for Jorge Cepernic dam does not exhibit significant changes of the hydrodynamic behavior of the stilling basin, except in a region downstream of the deflectors.
Moral Responsibility in Genocide: Humanity as both Victim and Perpetrator in Gil Courtemanche’s Un Dimanche à la piscine à Kigali

description: While the Rwandan Genocide was virtually absent from the news during the months of violence in the spring of 1994, there have since been many photos, films, books and news reports representing the atrocities. With all of these graphic depictions, it is important to pose the question of how one can justly and ethically represent the horror without overly simplifying the situation or exploiting the people by trying to sell the violence. In his hybrid novel, Un dimanche à la piscine à Kigali, Gil Courtemanche offers an example of an ethical representation of the terrifying events because he presents the crimes as committed both by and against humanity as a whole. He does not further perpetuate the racial stereotypes of Africans: either savage killer or worthless victim. Courtemanche refuses to further degrade the victims or to simplify the situation to make it seem like fictional horror, both of which would allow the reader to detach himself from the cruel reality. Instead, Courtemanche actually chooses to use voyeuristic literary strategy in order to implicate the reader in accusations against a world that failed in its response to the Rwandan genocide and to include the reader among the violated victims.

Mechanisation transformed space, in particular the household into an efficient machine, with industrial components and standardised dimensions (from the bathtub to the streamlined kitchen), while military manufacturing efficiencies and emerging technologies allowed consumer goods (from TV sets to Tupperware) to fill the middle class suburban home in the post-war era. This essay contemplates how logisticalisation, the latest incarnation of capitalist production, is permeating the design and conception of contemporary space through an exploration of the gadgets and objects that are increasingly used by the public as portals to the larger world of logistical flow. I refer to previous object-based theories of space in architecture as well as to Object-Orientated Ontology, a philosophical movement that elevates the meaning of objects as independent conscious entities beyond human agency. These serve to contextualise my own reading of logistical objects as manifestations that not only allow us intimacy with the larger and complex world of logistics, but more significantly, as dynamic shapers of new types of architectural and urban space, here characterised as territories of equivalence.

description: We examine the accretion of matter onto a black hole in scalar--tensor--vector gravity (STVG) also known as modified gravity (MOG). The gravitational constant is $G=G_{N} (1 + α)$ where $α$ is a parameter taken to be constant for static black holes in the theory. The MOG black hole is spherically symmetric and characterised by two event horizons. The matter falling into the black hole obeys the polytrope equation of state and passes through two critical points before entering the outer horizon. We obtain analytical expressions for the mass accretion rate as well as for the outer critical point, critical velocity and critical sound speed. Our results complement existing strong field tests like lensing and orbital motion and could be used in conjunction to determine observational constraints on MOG.

description: Desilting basins play an important role in run-of-river hydro power projects on Himalayan Rivers. These rivers carry huge amount of sediment with them, due to steep slopes and fragile geology of the region. The suspended sediment enters through the power intake and ultimately the power house. This causes heavy damage to the turbines and other under water parts. Therefore, desilting basins are provided to eliminate suspended sediment from the water conductor system. The design of desilting basin is verified on a physical model for 90% removal of suspended sediment coarser than 0.2 or 0.3 mm and efficacy of flushing tunnel below in transporting the settled sediment. Central Water and Power Research Station, Pune has conducted physical model studies for desilting basin for various hydro power projects in India and neighbouring countries. One such study, Hydraulic model studies for desilting basin for 500 MW Teesta-VI Hydro Electric Project, Sikkim is presented in this paper. Various design parameters such as length of desilting basin, length and bed slope of inlet transition, outlet transition, size of silt flushing tunnel, size and spacing of openings connecting main basin with silt flushing tunnel etc. were tested during the model studies. The results in terms of settling efficiency for 0.3 mm size particles were obtained.

description: In this thesis, we address the problem of service function chaining in a network. Currently, problems of chaining services in a network (i.e. service function chaining) can be broadly categorised into middlebox placement in a network and packet steering through middleboxes. In this work, we present a packet steering approach - One Pass Packet Steering (OPPS) - for use in multi-subscriber environments, with the aim that subscribers having similar policy chain composition should experience the same network performance. We develop and show algorithms with a proof of concept implementation using emulations performed with Mininet. We identify challenges and examine how OPPS could benefit from the Software Defined Data Center architecture to overcome these challenges. Our results show that, given a fixed topology and different sets of policy chains containing the same middleboxes, the end-to-end delay and throughput performance of subscribers using similar policy chains remains approximately the same. Also, we show how OPPS can use a smaller number of middleboxes and yet, achieve the same hop count as that of a reference model described in a previous work as ideal, without violating the subscribers' policy chains.
Relaxation of a classical spin coupled to a strongly correlated electron system

description: A classical spin which is antiferromagnetically coupled to a system of strongly correlated conduction electrons is shown to exhibit unconventional real-time dynamics which cannot be described by Gilbert damping. Depending on the strength of the local Coulomb interaction, the two main electronic dissipation channels, transport of excitations via correlated hopping and via excitations of correlation-induced magnetic moments, become active on largely different time scales. We demonstrate that this can lead to a prethermalization scenario which so far has been observed in purely electronic systems only and which is governed here by proximity to the divergent magnetic time scale in the infinite-U limit.

New Interfaces in the Automated Landscapes of Logistics
Creators: name: LeCavalier, Jesse
Publisher: name: FOOTPRINT
Year: 2018

description: Metaphors of flows are often used to describe aspects of logistics, thereby suggesting smooth and inevitable operations while also obscuring the frictions and contingencies that characterize the industry. This article explores the consequences and possibilities of these modes by first elaborating some aspects of logistical operations in order to connect them to the contemporary built environment. It looks at the architectural components of the company Walmart in order to present hypothetical scenarios related to the future of the logistical landscape. By connecting these visual experiments to questions of representation, automation, and systems thinking, the article explores the ways we might challenge and extend the possibilities of logistics.

description: The surface, container and conduit have become the primary infrastructural formats for logistics, operating and negotiating the scale of urbanism and landscape. ‘Surfaces’ are planes of mediation that typically function at a territorial scale as they are primarily implicated in a form of harvesting or collection. ‘Containers’ are architectural shells of enclosure often sited between the formats of surfaces and conduits – for storing, refining, or distributing a particular good. ‘Conduits’ are used to transfer matter and energy across vast distances, cutting through local settlements, political boundaries, ecosystems, and connecting to both containers and surfaces. These spatial formats typically reside in the ‘background’ of spatial design, yet are increasingly organising large tracts of land both in the hinterland as well as on the periphery of cities. Engaging in these background logistical formats holds promise for designers to have agency over territorial arrangements and could potentially offer alternate organisations that repay nature for its unpaid work. This article uses California’s Central Valley – an operationalised landscape that sustains the state and country’s food and energy needs – as a visual case study to reveal how these formats are deployed and organised.

description: We study the asymptotic Dirichlet problem for $f$-minimal graphs in Cartan-Hadamard manifolds $M$. $f$-minimal hypersurfaces are natural generalizations of self-shrinkers which play a crucial role in the study of mean curvature flow. In the first part of this paper, we prove the existence of $f$-minimal graphs with prescribed boundary behavior on a bounded domain $Ω\subset M$ under suitable assumptions on $f$ and the boundary of $Ω$. In the second part, we consider the asymptotic Dirichlet problem. Provided that $f$ decays fast enough, we construct solutions to the problem. Our assumption on the decay of $f$ is linked with the sectional curvatures of $M$. In view of a result of Pigola, Rigoli and Setti, our results are almost sharp.

description: Footprint 24 brings together housing-as-design with housing-as-policy and housing-as-market to discuss what is, today, the value of housing. It discusses how the architecture of housing plays a role in changing behavioural norms and models of subjectivation promoted by the neoliberal ideological agenda. The contributions included in this issue examine different ways of addressing the production of housing either as a social right or a commodity, or both combined. Reviewing cases from North America, Europe and Asia, they discuss the extent to which the social and economic agendas of the public sector and the market determine the architecture of housing. The background of the discussion is defined by a deadlock: the architectural discourse calls upon the state to re-provide housing and solve the crisis, while the neoliberal state is not interested in commissioning housing. Against this background, this issue examines how the architecture discipline can engage in new ways of responding to the neoliberal state of affairs, examining the entwined relation between ‘architecture’ as a cultural product and ‘housing’ as a socioeconomic need.
