Mutual-Friction Coefficients in Two-Dimensional Superfluids: From the Gross-Pitaevskii equation to the Hall-Vinen-Bekharevich-Khalatnikov Two-fluid Model
No full textWe start from the two-dimensional Gross-Pitaevskii equation (GPE) and develop algorithms for the ab-initio determination of the temperature (T) dependence of the mutual-friction coefficients, α and α, and the normal-fluid density Pn, which appear as parameters in the Hall-Vinen-Bekharevich-Khalatnikov (HVBK) two-fluid model for a superfluid. In the second part of our study, we elucidate the statistical properties of two-dimensional, homogeneous, isotropic superfluid turbulence in the simplified HVBK model, with values for the mutual-friction coefficients that are comparable to those we obtain from the first part of our study
The Park District Town Hall
No full textGraduation laboratory: Decorated Diagram Assignment: The design is of a district town hall for Osdorp (Amsterdam West) situated at the edge of Osdorp Park. The district town hall has some kind of presence in the area and addresses certain issues in relation to the location and the program. The issue of representation should be present and dealt with in some specific way. In this design for a district town hall in Osdorp, Amsterdam I will address the issue of representation by using the park as a special element in the sequences of use in and around the building and thus creating different ceremonial spaces. I want to emphasize that which unites the population of Osdorp; that which they have in common. The park is that which the people of Amsterdam-West have in common and adds a pleasant and important space, which softens the hard transition from private to public space which exists in Amsterdam West. The district town hall rises out of the ground and is "decorated" with natural stone and grass. This envelopes the diagram of a new state bureaucracy that is created in Osdorp Park. The state and the people should be represented in a city hall. The "ground" of Amsterdam West is special and out of it rises: the city hall. The park enters the building in many different ways, some more literal than others. There are more than two ceremonial spaces in a town hall. There are not just the Wedding Hall and the Council Hall, but in my opinion the Central (entrance) Hall and circulation spaces are also ceremonial spaces and should be treated as such. There are of course differences between the spaces, but making visitors and civil workers feel important through making spaces special is essential in a good town hall.Architectur
The Palace: City hall in Brussels
No full textThe graduation project “The palace” expands upon the notion of designing "City hall of Brussels." The studio raises questions on the relationship between the public realm and political space. It led our in-depth study of various forms of the town halls and public buildings that have evolved throughout history. It questions the nature of "political" and "public." In that respect, I found that the traditional city hall has a limited possibility of public participation. Making the city hall become the public domain of the city and encouraging the public to participate equally in politics has become an essential issue in my design.Architecture, Urbanism and Building Sciences | Interiors Buildings Citie
City Hall Brussels
No full textCurrently, a new administrative centre for the municipality of Brussels, Brucity, is under construction. A building that represents itself as a developers block and lacks any description of truly defined public space which allows the public to engage with its governance and its politicians. As a critique, a new city hall has been designed. Partly, by reusing the concrete skeleton of an existing apartment block, laying in between the given plot and the Boulevard Anspach. The new design tries to represents itself as a city hall through themes of openness, togetherness and generosity.Architecture, Urbanism and Building Science
Theory of spin Hall magnetoresistance
No full textWe present a theory of the spin Hall magnetoresistance (SMR) in multilayers made from an insulating ferromagnet F, such as yttrium iron garnet (YIG), and a normal metal N with spin-orbit interactions, such as platinum (Pt). The SMR is induced by the simultaneous action of spin Hall and inverse spin Hall effects and therefore a nonequilibrium proximity phenomenon. We compute the SMR in F|N and F|N|F layered systems, treating N by spin-diffusion theory with quantum mechanical boundary conditions at the interfaces in terms of the spin-mixing conductance. Our results explain the experimentally observed spin Hall magnetoresistance in N|F bilayers. For F|N|F spin valves we predict an enhanced SMR amplitude when magnetizations are collinear. The SMR and the spin-transfer torques in these trilayers can be controlled by the magnetic configuration.QN/Quantum NanoscienceApplied Science
The Ever Evolving Web: the Power of Networks
No full textIn this paper we consider the Web as a network of networks and reflect on its evolution, firstly by analyzing the reasons why it became the first truly ubiquitous hypertext system against all competitors and secondly by looking at how it has evolved from a network of linked documents to a system that facilitates social networking on a scale previously unimaginable and how it will evolve in the future as a network of linked data and beyond. The study of the Web—its evolution and its impact on society, on business and on government—is referred to as Web Science. We consider some of the major challenges of Web Science and discuss possible Web worlds of the future
(Table 2) Ba/Ca ratios of Cibicides wuellerstorfi and Orbulina universa from Bahaman sediment cores
No full textThis geochemical investigation utilizes Ba/Ca in the benthic foraminifer Cibicides wuellerstorfi from cores taken from the Bahama Banks and the Caribbean Sea to reconstruct changes in basal thermocline ventilation (800–1000 m) and middepth thermohaline circulation (1000–2000 m) in the western North Atlantic during the last glacial period, focusing on the deglacial transition. Previous studies show that an increase in ventilation of the North Atlantic subtropical gyre during the Last Glacial Maximum (LGM) caused a 30–60% decrease in labile nutrients within the thermocline layer. Using foraminiferal Ba/Ca as a proxy of refractory nutrients, increased ventilation during the LGM produced a depletion of less than 20% compared to Holocene values. Following glaciation, the production of Glacial North Atlantic Intermediate Water (GNAIW) shut down owing to the presence of meltwater in the surface ocean, which resulted in a decrease in ventilation, as seen by an enrichment of barium in the basal thermocline. GNAIW was subsequently replaced by barium-rich southern component water in the middepth western North Atlantic. Foraminiferal Ba/Ca data suggest a 38% contribution from southern component water to a depth as shallow as 1475 m and a 14% contribution at 1123 m during deglaciation
City Hall Bruxelles
No full textThe Chair of Interiors Buildings Cities located this year’s graduation project in the capital city of Belgium and the European Union, Brussels. Under the theme of ‘Palace’, the project is a City Hall on the previous site of the Les Halles Centrales in the 1870s, and is also known as the site for the earlier demolished Parking 58. The site will be soon occupied by ‘BruCity’, a new city administrative centre that will house 1500 employees of la Ville de Bruxelles, and this presented us the opportunity to critique whether the new fully glazed monument could really represent its governance transparency and offer the space where the citizens could have their political agency presented. Corridor was the major design motif and project’s thematic narrative. The outside room, corridor, as an informal space has its capability and power of accommodating the occurrence of the real negotiations happening before people entering the formal proceedings. The definition of corridor was broken down into a series of connective spaces. By the introduction of the corridor-ness in the project, it also aims to change and promote the working practice for a city hall which is the forefront of addressing the urgency of change in today’s society.<br/
