Challenges of prefabricated housing in China
Creators: name: Wu, Hongjuan
Publisher: name: A+BE | Architecture and the Built Environment
Year: 2021

description: Recently, the implementation of prefabricated housing (PH) has become prevalent in China to achieve sustainability while ensuring green construction, innovative products, and higher quality. However, numerous challenges arise, such as the overrun costs, inexperienced workers, and the inefficient management process. High transaction costs (TCs) occur in the PH project supply chain since additional efforts are consumed for overcoming these challenges. This study aims to seek insights into TCs of PH and investigate strategies for minimizing the TCs thus smooth the development process of PH projects. Three key elements have been addressed throughout the thesis: supply chain, stakeholders, and transaction costs. Four-step research is employed to uncover the TCs in the PH supply chain, collect the stakeholders’ perceptions, investigates the causes of TCs, and explore decisions for reducing TCs. This thesis identifies three types of TCs in Chinese PH projects by their nature: due diligence costs, negotiation costs, monitoring and enforcement costs. Private stakeholders in China’s PH industry put more of their attention on TCs related to the specificity of prefabrication. The simple and joint strategies are provided for reducing their benefits lost from the unexpected TCs. Additionally, the value of the governmental TCs has been revealed for reducing the TCs of PH, which inspires and supports the policymakers to develop a healthy policy environment.

In-situ H2O removal via hydorphilic membranes during Fischer-Tropsch and other fuel-related synthesis reactions
Creators: name: Rohde, Martin Philipp
Publisher: name: KIT Scientific Publishing

description: The general objective of this thesis was to explore the potential of in-situ H2O removal during fuel-related synthesis reactions with focus on in-situ H2O removal by hydrophilic membranes and by chemical reaction. It is demonstrated that in-situ H2O removal through vapour permeation during CO2 hydrogenation to Fischer-Tropsch hydrocarbons and during DME/DEE synthesis leads to increased conversion and yield levels, which are directly linked to the degree of H2O recovery.

description: The results of the research re-ported in this work show that tunable gap flux qubits have a potential for building quantum registers. Cavities coupled to flux qubits can be used for in-formation storage and transfer between qubits. SFS π-shifters provide a simple approach to bias multi-qubit circuits. A possibility to change the qubit resonance frequency while preserving qubit coherence enables implementation of switchable coupling between qubits and cavities.
How Heritage Learns
Creators: name: Clarke, Nicholas J
Publisher: name: A+BE | Architecture and the Built Environment
Year: 2021

description: How Heritage Learns explores the dynamics that come into play when public housing becomes valourised as heritage in the Netherlands and how that, in turn modulates the evolution of this protected housing. It builds on the foundation set by the thesis of Steward Brand, that buildings learn through the adaptation of their fabric to external forces: changing fashion, technologies and economy. This dissertation investigates different key drivers for change: Energy, Economy and Comfort (2E+Co). To understand how and why the housing heritage evolved over time, an ecology of ideas is developed that sees buildings as organisms evolving and learning in their environments, providing a multi-sided theoretic model for analysis. Three case studies are extensively explored: the Justus van Effen Quarter in Rotterdam (1921–22) and the King’s Wives of Landlust (1937–38) and Jeruzalem public housing complexes (1949–52), both in Amsterdam. These are all exemplary monuments of Dutch public housing and all three have undergone repeat renovations since their construction. The research not only highlighted their various learning cycles, but also uncovered exciting new information on their origins and histories. What sets public housing heritage apart is the presence of a Story. However, the case studies reveal that the Stones were modulated by dominant 2E+Co ambitions common to all public housing. Above all, How Heritage Learns shows that past promises of increased performance and efficiency were never fulfilled. Without structured reflective observation we are doomed to repeat the same mistakes. Such lessons are all the more important at a time when the built environment stands at the cusp of another revolution driven by environmental imperatives.

description: The $β$-delayed neutron emission probabilities of neutron rich Hg and Tl nuclei have been measured together with $β$-decay half-lives for 20 isotopes of Au, Hg, Tl, Pb and Bi in the mass region N$\gtrsim$126. These are the heaviest species where neutron emission has been observed so far. These measurements provide key information to evaluate the performance of nuclear microscopic and phenomenological models in reproducing the high-energy part of the $β$-decay strength distribution. In doing so, it provides important constraints to global theoretical models currently used in $r$-process nucleosynthesis.

Intracardiac electrograms

description: This work addresses major challenges of heart model personalization. Analysis techniques for clinical intracardiac electrograms determine wave direction and conduction velocity from single beats. Electrophysiological measurements are simulated to validate the models. Uncertainties in tissue conductivities impact on simulated ECGs. A minimal model of cardiac myocytes is adapted to the atria. This makes personalized cardiac models a promising technique to improve treatment of atrial arrhythmias.
Smart Campus Tools

Year: 2021

description: In recent years, the density on the Dutch university campus has increased substantially due to a continued growth of student populations. Campus managers face the challenge of accommodating the university’s students and employees mainly in the existing buildings, which are used ineffectively and inefficiently. In order to improve the space use on campus, campus managers need better information about space use. Therefore, this PhD dissertation proposes the use of Smart campus tools: a service or product with which information on space use is collected real-time to improve utilization of the current campus on the one hand, and to improve decision‑making about the future campus on the other hand. The main research question is: How can smart campus tools optimally contribute to the match between demand for and supply of space, both on the current campus and on the future campus? To answer the research question, this PhD dissertation explores the use of Smart campus tools in Dutch and international contexts, at universities and other organisations. Then, it researches how information from Smart campus tools can be properly connected to campus decision‑making processes. The results from this research are used to inform existing theories and draw lessons for practice.

THE IMPORTANCE OF GERMAN-TURKISH VOTERS IN TURKISH POLITICS
Creators: name: Hope, Wilson
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This thesis examines the important role of German-Turks in Turkish politics by bringing together the concept of clientelism and applying the concept to German-Turks within the sphere of Turkish domestic politics. This research explores the methods that the the Turkish government uses to cultivate the German-Turkish electorate and ensure that this loyalty is maintained in the future.Through two examples, the 2014 Presidential election and the 2017 Presidential referendum, the use of clientelist politics can be demonstrated. While existing literature discusses the long-time use of clientelism in Turkey proper, little contemporary research focuses on Turkeys’ German diaspora. This research contributes by exploring how Turkeys’ German constituency is impacted by many of the same factors of clientelism that also affect Turks in the Republic of Turkey.

description: The development of efficient low-loss electro-optic and nonlinear components based on silicon or its related compounds, such as nitrides and oxides, is expected to dramatically enhance silicon photonics by eliminating the need for non-CMOS-compatible materials. While bulk Si is centrosymmetric and thus displays no second-order (\c{hi}(2)) effects, a body of experimental evidence accumulated in the last decade demonstrates that when a strain gradient is present, a significant \c{hi}(2) and Pockels coefficient can be observed. In this work we connect a strain-gradient-induced \c{hi}(2) with another strain-gradient-induced phenomenon, the flexoelectric effect. We show that even in the presence of an extremely strong strain gradient, the degree by which a nonpolar material like Si can be altered cannot possibly explain the order of magnitude of observed chi^(2) phenomena. At the same time, in a polar material like SiN, each bond has a large nonlinear polarizability, so when the inversion symmetry is broken by a strain gradient, a small (few degrees) re-orientation of bonds can engender chi^(2) of the magnitude observed experimentally. It is our view therefore that the origin of the nonlinear and electro-optic effects in strained Si structures lies in not in the Si itself, but in the material providing the strain: the silicon nitride cladding.
From the Village to the Neighbourhood

description: This publication presents the study of urban transformation and opportunities for urban upgrading through the rehabilitation and recycling of neighbourhoods, exploring the past and present of the housing estates of the main Galician industrial cities in order to discover, on different scales, how the public housing projects built in the second half of the twentieth century were formed, how their urban integration process has taken shape, what the open spaces associated with public housing are like, and if they have served as a bridge between the public, the collective and the private, to end with recommendations that can help in participative processes of integral urban regeneration for better articulation, integration and urban cohesion of the open spaces included in the public project. The research proposes an alternative to urban development that avoids the need for new growth, the demographic abandonment of existing neighbourhoods, and their social and physical degradation. Housing estates with obsolete structures offer the greatest opportunities to rehabilitate and recycle open spaces and buildings based on the value of their intrinsic qualities, allowing for the introduction of new and efficient typologies in the city core. On a social level, the recycling and adaptive reuse of housing estates would improve the quality of the urban environment, the consolidation of civic networks and the strengthening of social cohesion. At the environmental level, this would reduce land use for real estate development, infrastructure construction and mobility needs, as well as waste production and energy consumption.

A Molecular Theory of the Nematic-Nematic Phase Transitions in Mesogenic Dimers

description: We present a simplified molecular model of mesogenic dimers consisting of two identical uniaxial mesogenic cores separated by a fixed-length spacer and allowed to assume only two, statistically equivalent, conformations which are non-planar and of opposite handedness. In the mean-field approximation, with additive interactions among the mesogenic cores, the model yields up to three positionally disordered phases, one isotropic and two nematic. The low temperature nematic phase ($\mathrm{N_X}$) has a local two-fold symmetry axis which is also a direction of molecular polar ordering and is tightly twisted about a macroscopic phase axis. The onset of polar ordering generates spontaneous chiral symmetry breaking, manifested primarily by the twisting of the polar director and the formation of chiral domains of opposite handedness. Within these domains the statistical balance between the two enantiomer conformations is shifted and the principal axes of the ordering tensors of the molecular segments twist at constant tilt angles with the helix axis. Key experimental results on the $\mathrm{N_X}$ phase of liquid crystalline dimers are discussed in the light of the theoretical predictions of the model, which are also contrasted with the predictions of the twist-bend nematic model.

Understanding comfort and health of outpatient workers in hospitals, a mixed-methods study

Publisher: name: A+BE | Architecture and the Built Environment
Year: 2021

description: Against the backdrop of an increasing need for healthcare, staff shortages and relatively high rates of sick leave, understanding of wellbeing (comfort and health) of hospital workers is important. This research aims to provide a contribution, through a mixed-methods approach, with broad and in-depth insights into comfort and health. Therefore, data have been collected from questionnaires, building inspections, interviews, and photos, and analysed with several techniques. Personal, work, and building-related aspects were included in data collection, because a preliminary literature review identified mutual relations with comfort and health. As previous studies on outpatient workers were missing, while staff is generally less satisfied with comfort than patients, this research focuses on staff in outpatient areas. To gain insights into the outpatient workers’ comfort and health, four important aspects are highlighted: differences in comfort in relation to room types, occupant profiles differentiated by the individuals’ preferences and satisfaction, changes of preferences due to contextual changes, and associations of health with building-related aspects. This research builds on previous studies which identified indoor environmental quality (IEQ) profiles of home occupants and school children. New are social comfort profiles, comparison between room types and contextual influence on preferences, as well as the studied occupant group and building. The study enables academical and practical exploration of preferences and perceptions of comfort and their integration in the design process. AnneMarie Eijkelenboom, architect with 25 years’ experience, is determined to improve wellbeing of occupants through expansion and integration of academical knowledge and practical experience in design of buildings.

From Seattle to Wall Street: counter-hegemonic protests and hegemonic (in)security
Creators: name: Paffhouse, Matthew D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: In this paper, I analyze the neoliberal ruling class' reaction to counter-hegemonic protests in order to shed light on its perceived security. This analysis is grounded in a neo-Gramscian theoretical framework, and is conducted through a comparative analysis of two counter-hegemonic movements: the 1999 Battle at Seattle and the 2011 Occupy Wall Street. To provide argumentative clarity, I have devised a categorization of hegemonic reactions to counter-hegemonic movements. This categorization is based on a division between the different actors constituting the neoliberal ruling class, and whether their dominant responding strategy is strong or weak, with a strong response indicative of greater insecurity, and the latter security. The three ruling class actors analyzed are the corporate media, the government, and the police and security apparatus. Based on the change in response to the two protests, I conclude that the perceived security of the neoliberal ruling class has decreased since 1999.

description: Assigning the farmer versus breeder shares of the economic value derived from improved crop varieties remains a contentious issue, with real world food security, poverty alleviation and environmental health consequences. Drawing on ideas regarding the economics of (sequential) innovation that align especially well with varietal improvement, we introduce a new way of attributing the added value derived from crop varietal improvement between current breeding programs and the recent and distant past efforts of prior (formal and farmer) breeders. We then apply our new attribution method to entirely new data we compiled over the past few years for the development and uptake of Canadian wheat varieties to investigate the implications of different attribution rules for breeder versus farmer benefits. We use our illustrative empirical results to guide and recommend policy reforms regarding the multilateral system (MLS) of access and benefit sharing encapsulated in the International Treaty on Plant Genetic Resources for Food and Agriculture. Our proposed reforms are designed to both eliminate the inventive downsides of the MLS Treaty levy (effectively a tax on seed sales) and to better align MLS goals with other policies and practices associated with the plant breeders rights (PBRs) embodied in the International Convention for the Protection of New Plant Varieties (UPOV), including end-point royalties that represent a return on innovative effort levied on grain sales. The Treaty levy is clearly failing to generate sufficient revenues to fully achieve its stated genetic conservation and benefit sharing goals. The evidenced-based policy options we identify can constitute a win-win fix that realigns benefit sharing equity outcomes with innovation incentives for crop breeding throughout the world.

Disclosing Interstices

description: Leftover spaces are neglected and obsolete spaces within the city. As they are temporarily unoccupied by defined urban functions, leftover spaces provide unique “interstitial conditions” that open for wild species as well as different informal social activities, offering crucial complements to the formal and defined urban spaces. In this context, the design of leftover spaces poses a paradox between the practice of design that projects a set of definitions onto the site, and the indeterminacy of leftover spaces that opens for appropriation and interpretation. By recognizing this paradox within the design of leftover spaces, this thesis strives to explore open-ended design approaches that engage leftover spaces without losing their essential qualities of indeterminacy. Three case studies—Valby Smedestræde 2 in Copenhagen, Le Jardin Du Tiers-Paysage [the Garden of the Third Landscape] in Saint-Nazaire, and the Dalston Eastern Curve Garden in London are scrutinized with a uniform framework consisting of four lenses: the morphological, social, ecological and material lens. The plan, the section, the perspective and axonometric drawings are used as tools to examine the cases and further, to represent the results of reading through each lens. The study delivers four general modi operandi—disclosing, selecting, founding, and sustaining—for engaging with the interstitial condition of leftover spaces. This thesis further invites for an exploration on the role of “gardeners”, nurtures and balances diverse social and ecological practices in the on-going transformation of the site.

Obesity induces metabolic alterations of T lymphocytes in influenza-vaccinated adults
Creators: name: Green, William
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Obesity increases the risk for infection due to impairments in T cell activation and function. Although the metabolic profiles of T cells dictate their function, what remains unknown is if obesity alters T cell metabolism, thereby impairing function. This study examined the metabolic profiles of T cells from healthy weight and obese white women. We demonstrated that obesity alters the metabolic profile of quiescent and activated peripheral blood mononuclear cells, and isolated CD4 and CD8 T cells. T cells from obese non-diabetic subjects exhibited higher rates of aerobic glycolysis and mitochondrial respiration compared to obese metformin-treated diabetic subjects. This ability of metformin to lower T cell metabolism in obese diabetics to healthy weight levels, despite elevated serum glucose, suggests that metformin’s mechanism of action directly impacts T cells. These results suggest that perturbations in T cell metabolism are the mechanism for impairment of T cell function in obese adults.
Computational Design of Indoor Arenas (CDIA)

description: Indoor arenas are important public buildings catering for various activities (e.g., sports events, stage performances, assemblies, exhibitions, and daily sports for the public) and serving as landmarks in urban contexts. The multi-functional space and long-span roof structure of an indoor arena are highly interrelated, which impact the multi-functionality and structural performance and mainly define the overall form of the building. Therefore, it is crucial to integrate the multi-functional space and long-span roof structure to formulate proper forms for indoor arenas, in order to satisfy various design requirements during the conceptual design. This thesis aims at formulating a computational design method, ‘Computational Design of Indoor Arena (CDIA)’, to support the conceptual design of indoor arenas by using the computational techniques of parametric modelling, Building Performance Simulations (BPSs), Multi-Objective Optimizations (MOOs), surrogate models based on Multi-Layer Perceptron Neural Network (MLPNN), and clustering based on Self-Organizing Map (SOM clustering). In the formulation of CDIA, these techniques are modified, improved and organized into five components and three workflows, to satisfy the demands of the conceptual design of indoor arenas.

description: Biomechanics of traumatic dental injures (TDI) is not well understood. Computer-based simulation/finite element method--FEM may facilitate understanding TDI. A realistic 3-D FEM of a maxilla with multi-tooth loading will enhance TDI understanding. METHODS: FE model of a complete maxilla including alveolar process, enamel, dentin, pulp, and PDL was constructed using CT imaging of an 18 year old female. Single and multi-incisor TDI was simulated using horizontal, oblique, and vertical loading with static point forces of 200 N (right central incisor) and 400 N (both central incisors). Stress/strain/displacement of affected/adjacent teeth and supporting structures were evaluated based on TDI scenario. RESULTS: Horizontal loading experienced most stress in all hard/soft tissues compared to other loading scenarios. Double loading experienced approximately double stress/displacement. Teeth in isolation to other structures experienced most stress while PDL experienced little. CONCLUSION: Anatomically accurate full maxilla FE model was constructed. FE model output approximates clinical presentations of many TDI scenarios. When model is loaded horizontally FEA simulates buccal plate fracture. Understanding TDI biomechanics will allow better diagnosis, treatment, and prevention of dentoalveolar injuries.

description: The low-energy muon facility at PSI provides nearly fully polarized positive muons with tunable energies in the keV range to carry out muon spin rotation (LE-muSR) experiments with nanometer depth resolution on thin films, heterostructures, and near-surface regions. The low-energy muon beam is focused and transported to the sample by electrostatic lenses. In order to achieve a minimum beam spot size at the sample position and to enable the steering of the beam in the horizontal and vertical direction, a special electrostatic device has been implemented close to the sample position. It consists of a cylinder at ground potential followed by four conically shaped electrodes, which can be operated at different electric potential. In LE-muSR experiments, an electric field at the sample along the beam direction can be applied to accelerate/decelerate muons to different energies (0.5-30 keV). Additionally, a horizontal or vertical magnetic field can be superimposed for transverse or longitudinal field muSR experiments. The focusing properties of the conical lens in the presence of these additional electric and magnetic fields have been investigated and optimized by Geant4 simulations. Some experimental tests were also performed and show that the simulation well describes the experimental setup.

Space layout and energy performance

description: Studies have shown that space layout design can impact the building energy performance (BEP). However, its isolated effect on the BEP has not been identified yet. Performative computational architecture has proven to be effective to improve the BEP. However, only a few studies have tried to apply the performative computational architecture to space layout design. This research aims to investigate how space layout affects BEP, and to develop a computational optimisation method for space layout to improve the BEP of office buildings. Firstly, the mechanism on how space layout affects the BEP and how much energy is affected by space layout were identified through literature review and simulation. 11 layouts with different function allocations were simulated and compared. The outcome showed that layout variance affected lighting the most, and the maximum difference happened in Harbin, being 46% without shading and 35% with shading. As a follow-up, another literature review was conducted, which identified the functional requirements of space layout design, methods for automatic generation of space layout, and requirements for energy performance optimisation. In addition, a computational method was developed to optimise space layout design for energy performance improvement, regardless of functional requirements. As a result, the relationship between space layout and energy demands were recognised. In conclusion, space layout has proven to be a significant influence on the BEP, and conscientious design can improve it. For optimal energy performance, manual design of space layout is not feasible; in order to do that, a computational approach is needed.

description: This work is about random measures stationary with respect to a possibly non-transitive group action. It contains chapters on Palm Theory, the Mass-Transport Principle and Ergodic Theory for such random measures. The thesis ends with discussions of several new models in Stochastic Geometry (Cox Delauney mosaics, isometry stationary random partitions on Riemannian manifolds).

description: We study the role of the Hall current and electron inertia in collisionless magnetic reconnection within the framework of full two-fluid MHD. At spatial scales smaller than the electron inertial length, a topological change of magnetic field lines exclusively due to electron inertia becomes possible. Assuming stationary conditions, we derive a theoretical scaling for the reconnection rate, which is simply proportional to the Hall parameter. Using a pseudo-spectral code with no dissipative effects, our numerical results confirm this theoretical scaling. In particular, for a sequence of different Hall parameter values, our numerical results show that the width of the current sheet is independent of the Hall parameter while its thickness is of the order of the electron inertial range, thus confirming that the stationary reconnection rate is proportional to the Hall parameter.
Solar Geometry in Performance of the Built Environment

description: As part of the passive design strategy, the development of computational solar envelopes plays a major role to construct a cooperative environmental performance exchange between new buildings and their local contexts. However, the state-of-the-art computational solar envelopes pose a great challenge in understanding site characteristics from a given context. Existing methods predominantly construct 3D context models based on basic architectural geometric shapes, which are often isolated from the surrounding properties of local contexts (i.e., vegetation, materials). Thus, they only focus on context-oriented buildings and energy quantities that unfortunately lack a contextual solar performance analysis. It is clear that this condition may result in a fragmented understanding of the local context during the design and simulation process. With the potential application of attribute point cloud information, it is necessary to consider relevant parameters such as surface and material properties of existing contexts during the simulation of solar geometries, which are currently absent in computational frameworks. As such, the new method is required to enable architects not only to measure specific performances of the local context but also to identify vulnerable areas that may affect the proposed design. This research focuses on exploring an integrated computational design method for solar geometry based on solar and shading envelopes, and geometric and radiometric information from point cloud data. In particular, two computational models consisting of SOLEN (Subtractive Solar Envelopes) and SHADEN (Subtractive Shading Envelopes) are developed, which are applied to temperate and tropical climates, respectively. In design practice, these models help architects to produce informed-design decisions towards high-performed building massing.

description: In order-driven markets, limit-order book (LOB) resiliency is an important microscopic indicator of market quality when the order book is hit by a liquidity shock and plays an essential role in the design of optimal submission strategies of large orders. However, the evolutionary behavior of LOB resilience around liquidity shocks is not well understood empirically. Using order flow data sets of Chinese stocks, we quantify and compare the LOB dynamics characterized by the bid-ask spread, the LOB depth and the order intensity surrounding effective market orders with different aggressiveness. We find that traders are more likely to submit effective market orders when the spreads are relatively low, the same-side depth is high, and the opposite-side depth is low. Such phenomenon is especially significant when the initial spread is 1 tick. Although the resiliency patterns show obvious diversity after different types of market orders, the spread and depth can return to the sample average within 20 best limit updates. The price resiliency behavior is dominant after aggressive market orders, while the price continuation behavior is dominant after less-aggressive market orders. Moreover, the effective market orders produce asymmetrical stimulus to limit orders when the initial spreads equal to 1 tick. Under this case, effective buy market orders attract more buy limit orders and effective sell market orders attract more sell limit orders. The resiliency behavior of spread and depth is linked to limit order intensity.
