Brownfield redevelopment: Towards a comprehensive approach
Creators: name: Kiseleva, Tatiana
Publisher: name: International Planning History Society Proceedings
Year: 2022

description: Brownfield redevelopment is one of the major issues many developed cities have faced in the last decades. This type of urban action often requires its own operating models and regulations due to the complexity of land use, larger geographical scale as well as environmental challenges. To understand the specifics of the problem we take a comparative look at brownfield redevelopment in Russian and French cities.

description: D6.5 “Report on the contribution to standardization” will collect the actions performed forthe contribution to standardization from PASSENGER and the results obtained. Thecontribution to standardization seeks to transfer selected results of PASSENGER tostandards (EN/CLC/ISO/IEC).This document builds up on the already defined strategy for the contribution tostandardization from PASSENGER that has been made available in M12 and additionallyfocusses on the carried-out activities by M24. It describes the contacts that could alreadyestablished to relevant standardization technical committees and outlines how the nextsteps will look like.The transfer of the results of PASSENGER to standards that are widely recognized by theindustry and that are developed in a system external to the Consortium will ease the marketuptake of these results and their impact beyond the duration of the project. Additionally, thestandardization system is used as a targeted dissemination channel towards thestakeholders represented in the standardization committees.D6.5 is the second deliverable for Task T6.4 “Standardization” inside WP 6 “Industrialexploitation and pilot replication and commercialization”. It is based on the conclusions ofD6.4 “Report on the standardization landscape and applicable standards” that included theinformation on the relevant existing and ongoing standards and the relevant standardizationtechnical committees to facilitate the use of existing knowledge and the compatibility andthe interoperability of the results.The Spanish Association for Standardization (UNE), as National Standardization Body(NSB), member of CEN-CENELEC, is partner of PASSNEGER to provide support regardingthe standardization tasks included in the project.The schedule of the actions described in this document is open to changes according to theprogress of the project and the standardization landscape.

Subjects: Differential settlement : member geometry: beam span length :column height: frame force: structural response

description: Differential settlement is unequal settlement of structural components. It is a reality
 engineers deal with when a structure rests on soil with poor bearing capacity. Differential
 settlement brings forth unbalanced strain energy in structural members and through inelastic
 action redistribution of internal forces occur among frame structural members.
 This research work presents analytical study on effects of member geometry on frame force
 redistribution. 3D model of 2x2 bay one story reinforced
 concrete structure was modeled and analyzed for gravity loading and prescribed 75mm
 differential settlement using ETABS 2016 software Critical
 Critical parameters used as variables in the study are length of beam,
 height of column, moment inertia of beam, moment of inertia of column, number of story, and
 number of bays. Results of this study indicate as beam span length and column height increased,
 redistributed frame forces decreased whereas decrement in moment of inertia of beam and
 column resulted lesser frame forces, for same story level, as number of bays increased, it is
 observed that frame forces also increase,

description: Hydroxylamine (NH$_{2}$OH) and methylamine (CH$_{3}$NH$_{2}$) have both been suggested as precursors to the formation of amino acids and are therefore of interest to prebiotic chemistry. Their presence in interstellar space and formation mechanisms, however, are not well established. We aim to detect both amines and their potential precursor molecules NO, N$_{2}$O and CH$_{2}$NH towards the low-mass protostellar binary IRAS 16293--2422, in order to investigate their presence and constrain their interstellar formation mechanisms around a young Sun-like protostar. ALMA observations from the unbiased, high angular resolution and sensitivity Protostellar Interferometric Line Survey (PILS) are used. Spectral transitions of the molecules under investigation are searched for with the CASSIS line analysis software. CH$_2$NH and N$_{2}$O are detected for the first time towards a low-mass source, the latter molecule through confirmation with the single-dish TIMASSS survey. NO is also detected. CH$_{3}$NH$_{2}$ and NH$_{2}$OH are not detected and stringent upper limit column densities are determined. The non-detection of CH$_{3}$NH$_{2}$ and NH$_{2}$OH limits the importance of formation routes to amino acids involving these species. The detection of CH$_{2}$NH makes amino acid formation routes starting from this molecule plausible. The low abundances of CH$_2$NH and CH$_{3}$NH$_{2}$ compared to Sgr B2 indicate that different physical conditions influence their formation in low- and high-mass sources.

Technical Assistance of the Soviet Specialists to China on Urban Planning in 1949-1959
Creators: name: Li, Hao
Publisher: name: International Planning History Society Proceedings
Year: 2022

description: A highlight of the urban planning activities in the early days of the People’s Republic of China was the massive number of professional Soviet specialists sent to technically assist China with urban planning. This was also a unique phenomenon in the international urban planning sector. More than forty Soviet specialists, who could be categorized into four series, were sent to China over a 10-year period to provide technical assistance, commencing from the arrival of the first series of Soviet municipal engineering specialists in August 1949 to the return of the last series of specialists in May 1959. By virtue of the technical assistance of the Soviet planners China managed to learn from Soviet planning theory in its entirety and developed urban reconstruction & expansion plans for a number of existing megacities as well as a number of important emerging industrial cities. Furthermore, thanks to the Soviet specialists, China was able to train and acquire a multitude of first-generation urban planners of its own who instilled into modern Chinese planning model a “cultural gene” which, originating primarily from the Soviet model, characterized socialist urban planning.

description: The pyrochlore oxides $A_2B_2$O$_7$ exhibit a complex interplay between geometrical frustration, electronic correlations, and spin-orbit coupling, due to the lattice structure and active charge, spin, and orbital degrees of freedom. Understanding the properties of these materials is a theoretical chalenge, because their intricate nature depends on material-specific details and quantum many-body effects. Here we review our recent studies based on first-principles calculations and quantum many-body theories for 4$d$ and 5$d$ pyrochlore oxides with $B$=Mo, Os, and Ir. In these studies, the spin-orbit coupling and local electron correlations are treated within the LDA+$U$ and LDA+dynamical mean-field theory formalisms. We also discuss the technical aspects of these calculations.

Subjects: PMSM, FOC, Popov stability, Lyapunov stability, Stator Current Based MRAS, Sensorless

description: Nowadays many studies focusing on for the elimination of the speed and position sensors for
 Field oriented control (FOC) based speed control of AC machines. It avoids the drawback of
 the sensors such as, the required additional mounting space, decreasing the reliability in harsh
 environments and increase the cost of the machines. In this work, sensorless speed control of
 permanent magnet synchronous motor (PMSM) using model reference adaptive system
 (MRAS) is proposed. Stator current based Model reference adaptive system is used to estimate
 the speed of the motor and also the adaptation mechanism constructed by using Popov hyper
 stability principle. The main idea here is that the reference model, which is the permanent
 magnet synchronous motor (PMSM), d-q axis stator current output compared with the
 adjustable model d-q axis current and their difference pass through adaptation method to
 estimate the speed of the motor. In addition, model reference adaptive system (MRAC) with
 Lyapunov stability adaptation mechanism is employed for speed control of machine which
 decrease the dependence on system parameters significantly. This controller parameters are
 tuned in such a way that the plant follows the reference model. The effectiveness of the
 proposed system is tested through computer simulation. The software used to test the
 effectiveness of the proposed system is MATLAB/Simulink. The system gives good
 performance at loaded and no load conditions and hence it can work with different load torque
 conditions and system parameter variation. The output of the proposed system compared with
 the result of the system using conventional proportional and integral (PI) speed controller
 shows better performance.

Publisher: name: International Planning History Society Proceedings
Year: 2022

description: Industrialisation and the related rise of a modern city in Eastern Europe have had very different development trajectories than those in Western Europe due to the changes of both political and economic systems. This can be seen on the example of the development of industry in six middle-size northern Serbian cities in Pannonian Plain that passed through three noticeable periods: (1) early industrialisation in an emerging capitalism of Austro-Hungarian Monarchy in late 19th and early 20th century, (2) planned industrialisation in socialism in the second half of 20th century of Yugoslavia and (3) de/reindustrialisation tendencies in post-socialist transition since the 1990s. All three periods of industrial development have left immense consequences on the cities, their urban fabric and land use. Hence, the aim of this paper is to explain the pace of industrial development in six selected cities since the rise of capitalism in early modern periods in 18th century, as well as their spatial and social impact on urban fabric and urban planning and regulation thereof. This research thereby gives an insight into the locally rare examination of an industry-driven urban development, contributing in the understanding of this, generally underestimated planning legacy.

Alphabet-Dependent Bounds for Linear Locally Repairable Codes Based on Residual Codes

description: Locally repairable codes (LRCs) have gained significant interest for the design of large distributed storage systems as they allow a small number of erased nodes to be recovered by accessing only a few others. Several works have thus been carried out to understand the optimal rate-distance tradeoff, but only recently the size of the alphabet has been taken into account. In this paper, a novel definition of locality is proposed to keep track of the precise number of nodes required for a local repair when the repair sets do not yield MDS codes. Then, a new alphabet-dependent bound is derived, which applies both to the new definition and the initial definition of locality. The new bound is based on consecutive residual codes and intrinsically uses the Griesmer bound. A special case of the bound yields both the extension of the Cadambe-Mazumdar bound and the Singleton-type bound for codes with locality $(r, δ)$, implying that the new bound is at least as good as these bounds. Furthermore, an upper bound on the asymptotic rate-distance tradeoff of LRCs is derived, and yields the tightest known upper bound for large relative minimum distances. Achievability results are also provided by deriving the locality of the family of Simplex codes together with a few examples of optimal codes.

description: Based on the two successive plans of the University of North Carolina (UNC) at Chapel Hill from 2001 to 2010, we review the conservation and planning philosophy of the five landmark landscapes in the master plan, and the historical context, content and aesthetic culture of the plans, with an emphasis on the objectives, principles, methods and implementation of the historic landscape plan. Since its foundation in 1795, the University of North Carolina has gone through five different phases of landscape planning and management, directed by a professor of natural philosophy, a historian, a botanist, a landscape architect and an architect. The spatial form of its campus plan reflects the great changes in the economic development of the United States over 200 years, reflecting the process of American campus construction during that period. It is argued that the guiding principles developed by the University of North Carolina at Chapel Hill for the preservation of historic landscapes reflect the important role that human intervention and the power of restraint play in the preservation of landscape heritage.

description: Based on the historical geographic database of the cities subordinated to the Ming Great Wall defense system and the Northern Song fortress defense system built by the research team, the history of military settlements in northwest China and their urban defense structure were traced. A comparative analysis of the spatial characteristics of urban defense planning during the Song and Ming Dynasties using settlement morphology data revealed significant differences in urban defense planning in the two eras. Focusing on typical urban settlements that span two historical periods and have continued into the present time, we analyzed continuous space-time slices of ancient urban defense spaces and explored their historical causes using ancient urban maps, local chronicles, and aerial photographs. Finally, the historical evolution sequence of ancient urban defense spaces was determined.

description: Single-electron capacitance spectroscopy precisely measures the energies required to add individual electrons to a quantum dot. The spatial extent of electronic wavefunctions is probed by investigating the dependence of these energies on changes in the dot confining potential. For low electron densities, electrons occupy distinct spatial sites localized within the dot. At higher densities, the electrons become delocalized, and all wavefunctions are spread over the full dot area. Near the delocalization transition, the last remaining localized states exist at the perimeter of the dot. Unexpectedly, these electrons appear to bind with electrons in the dot center.
Islamic Perspectives on Veganism

subject: FOS: Philosophy, ethics and religion

description: This study explores the key ethical questions raised by veganism and how Muslim religious scholars and intellectuals, both in classical and modern times, (should) have addressed them. The first part studies how theological concepts such as divine justice, stewardship, and the hierarchy of creation have been used to advocate for worldviews varying from anthropocentrism and benevolent anthropocentrism to ecocentrism and ecofeminism. These are compared with secular discourses on moral veganism. The thesis also draws parallels between and examines the intersection of animal rights discourses with other social justice discourses such as those of feminism and abolitionism and situates them within the larger discourse regarding the existence and nature of hierarchy. The next part focuses on the practical implications of these theological stances, by examining the resulting Shari'a-centred, maqāṣid-centred, and ādāb-centred approaches, and the juristic rulings or ethical commands that they espouse with regard to the treatment of animals. Finally, the thesis assesses how these philosophical and theoretical perspectives can be, or have been, used to address the issue of factory farming, which is one of the major causes of climate change, food and water insecurity, and the other economic, social, environmental, and medical costs linked to it. I conclude that hierarchical worldviews where animals are seen as inferior can also serve to protect their interests and may even lead to veganism on the basis of mercy and compassion. Moreover, adopting an ethics-based approach can help improve the welfare of animals. While there are inklings of how ritual slaughter may be reconsidered in the status quo, this issue requires further exploration. Muslim scholars ought to further analyse the issues raised in this study and devise rulings that take into account our current circumstances.
How pump-probe differential reflectivity at negative delay yields the perturbed free-induction-decay: Theory of the experiment and its verification

description: While time-resolved pump-probe differential reflectivity and transmitivity measurements are routinely used to monitor the population relaxation dynamics on the subpicosecond time scale, it is also known that the signal in the negative delay can yield direct signatures of the perturbed-free-induction-decay of polarization. Yet this technique, especially in reflection geometry, has never been popular because the experiment is conceptually not very intuitive. Coherent dynamics is therefore usually studied using the more complex four-wave-mixing experiments. Here we derive from first principles the simplest possible but mathematically complete framework for the negative delay signal in both the time and the spectral domains. The calculation involving the optical Bloch equations to describe the induced polarization and the Ewald-Oseen idea to calculate the reflected signal as a consequence of the free oscillations of perturbed dipoles, also explicitly includes the process of lock-in detection of a double-chopped signal after it has passed through a monochromator. The theory is compared with experiments on high quality GaAs quantum well sample. The dephasing time inferred experimentally at 4 K compares remarkably well with the inverse of the absorption linewidth of the continuous-wave photoluminescence excitation spectrum. Spectrally resolved signal at negative delay calculated from our theoretical expression nicely reproduces the coherent spectral oscillations, although exact fitting of the experimental spectra with the theoretical expression is difficult. This is on account of additional resonances present in the sample corresponding to lower energy bound states.

Study on the Changing of Traditional Urban Fabric in Shanghai Old Town

Publisher: name: International Planning History Society Proceedings
Year: 2022

description: During the regeneration process of historic built environment in the megacities like Shanghai, traditional urban fabric and modern urban fabric have different spatial characteristics. The traditional urban fabric in Shanghai, which is represented by Lilong houses, can offer highly shared public and semi-public spaces in daily life. Unfortunately, after nearly 20 years of large-scale renewal process, there is only about 40% of the traditional urban fabric retained in Shanghai Old Town, which deeply depends on the delineation and planning requirements of Historic Conservation Area. In the past two years, in the planning of core conservation zone, Shanghai tries a new reconstruction way by demolishing old house and building new house with similar height and density as the former ones, to maintain the urban fabric and improve the environment quality. Taking Luxiangyuan as an example, the spatial pattern was inherited to a certain extent, the style and the elements of new house echoed with Lilong buildings. This paper finds that confronting with the challenges of disappearing traditional urban fabric, the former planning and "fabric reconstruction" practice has certain limitations, such as the disappearance of the high sharing character of roads and alleys.

We work with a set of network models of random and scale free type, generated with specific features of clustering and assortativity. Various strategies like random deletion of links, or deletions based on betweenness centrality and degrees of source and target nodes, are used to breakdown the networks. The robustness of the networks to the sustained loss of links is studied in terms of the sizes of the connected components and the inverse path lengths. The effects of clustering and 2-node degree correlations, on the robustness to attack, are also explored. We provide specific illustrations of our study on three real-world networks constructed from protein-protein interactions and from transport data.

description: Antibiotic pollution of water resources is a global problem, and the development of new treatments for destroying antibiotics in water is a priority research. We successfully manufactured recyclable magnetic Fe3O4/g-C3N4 through the electrostatic self-assembly method. Selecting tetracycline (TC) as the target pollutant, using Fe3O4/g-C3N4 and H2O2 developed a heterogeneous optical Fenton system to remove TC under visible light. Fe3O4/g-C3N4 was systematically characterized by SEM, TEM, XRD, FTIR, XPS, DRS, and electrochemical methods. The removal efficiency of 7% Fe3O4/g-C3N4 at pH = 3, H2O2 = 5 mM, and catalyst dosage of 1.0 g/L can reach 99.8%. After magnetic separation, the Fe3O4/g-C3N4 photocatalyst can be recycled five times with minimal efficiency loss. The excellent degradation performance of the prepared catalyst may be attributed to the proper coupling interface between Fe3O4 and g-C3N4 which promotes the separation and transfer of photogenerated electrons. Photogenerated electrons can also accelerate the conversion of Fe3+ to Fe2+, thereby producing more ˙OH. The new Fe3O4/g-C3N4 can be used as a raw material for advanced oxidation of water contaminated by refractory antibiotics.

description: We derive constraints from flavor and LHC searches on charmphilic contributions to the muon anomalous magnetic moment with a single leptoquark. Only the scalar leptoquarks $S_1$ and $R_2$ are relevant for the present analysis. We find that for $S_1$ some parameter space remains consistent at $2σ$ with the Brookhaven National Laboratory measurement of the muon $g-2$, under the assumption that the left-type coupling between the muon and the charm quark is a free parameter. The surviving parameter space is, on the other hand, going to be probed in its entirety at the LHC with 300/fb of luminosity or less. All other possibilities are excluded by the LHC dimuon search results in combination with several flavor bounds, which together require one to introduce sizable couplings to the top quark to be evaded.

description: The various responses to the economic situation and the excruciating issue of housing during the long, unstable period of Franco’s regime, during which there was high immigration and steep growth in large cities, led to the consolidation of high percentages of homeownership. Homeownership was particularly notable in the working-class suburbs of urban agglomerations. This was a real cultural mutation that, due to its divergence from European housing policies, is a good focus of analysis to explore some specific characteristics of the housing problem during the Franco regime. Through a literature review and the use of primary sources (building permits, building and housing censuses and population registers), the ongoing research on Barcelona questions whether the divergence from other European countries is mainly a Falangist cultural legacy, as suggested recently, or more closely related to the process of economic liberalisation. As greater access to homeownership coincided with a revolution in ways of living and new relations with the neighbourhood, it should also be questioned whether it influenced the high number of neighbourhood movements during the decline of Franco’s regime.

A Study on the Spatial Structure of Jinan in the Qing Dynasty

description: Taking Jinan as the research object, this paper attempts to construct the spatial structure of Jinan in the Qing dynasty through documentary research and historical map transfer. The study was conducted on the following three levels: macro, meso and micro. Specifically, in macro-level, the study attempted to construct the spatial structure by sorting out the natural environment and transport elements, Qing dynasty administrative divisions and urban functions within the city limits. In meso-level, the study focused on the interaction of mountain and river with urban siting and urban axes. In micro level, the study focused on the organisation of space within the city. The study found that the eight counties within the city limits of the Qing Dynasty were all centres of defence, political, economic, cultural, and educational functions, together forming a multi-centre network structure. Among the 8 counties, Licheng County was located between mountains and rivers, and used the natural elements to establish an effective defence system. The city formed five main axes with the mountains and rivers, creating a harmonious and close connection with the surrounding environment. Inside the city, the space was organised through lishe, forming a spatial structure with the north-south road as the skeleton. By establishing the spatial structure of the entire administrative region and its multiple layers, the study hopes to provide historical advice to current planning practice.

description: We use brane configurations and SL(2,Z) symmetry of the type IIB string to construct mirror N=2 supersymmetric gauge theories in three dimensions. The mirror map exchanges Higgs and Coulomb branches, Fayet-Iliopoulos and mass parameters and U(1)R symmetries. Some quantities that are determined at the quantum level in one theory are determined at the classical level of the mirror. One such example is the complex structure of the Coulomb branch of one theory which is determined quantum mechanically. It is mapped to the complex structure of the Higgs branch of the mirror theory, which is determined classically. We study the generation of N=2 superpotentials by open D-string instantons in the brane configurations.

description: Antibiotic pollution of water resources is a global problem, and the development of new treatments for destroying antibiotics in water is a priority research. We successfully manufactured recyclable magnetic Fe3O4/g-C3N4 through the electrostatic self-assembly method. Selecting tetracycline (TC) as the target pollutant, using Fe3O4/g-C3N4 and H2O2 developed a heterogeneous optical Fenton system to remove TC under visible light. Fe3O4/g-C3N4 was systematically characterized by SEM, TEM, XRD, FTIR, XPS, DRS, and electrochemical methods. The removal efficiency of 7% Fe3O4/g-C3N4 at pH = 3, H2O2 = 5 mM, and catalyst dosage of 1.0 g/L can reach 99.8%. After magnetic separation, the Fe3O4/g-C3N4 photocatalyst can be recycled five times with minimal efficiency loss. The excellent degradation performance of the prepared catalyst may be attributed to the proper coupling interface between Fe3O4 and g-C3N4 which promotes the separation and transfer of photogenerated electrons. Photogenerated electrons can also accelerate the conversion of Fe3+ to Fe2+, thereby producing more ˙OH. The new Fe3O4/g-C3N4 can be used as a raw material for advanced oxidation of water contaminated by refractory antibiotics.

description: In this paper we consider the following class of fractional Kirchhoff equations with critical growth: \begin{equation*} \left\{ \begin{array}{ll} \left(\varepsilon^{2s}a+\varepsilon^{4s-3}b\int_{\mathbb{R}^{3}}|(-Δ)^{\frac{s}{2}}u|^{2}dx\right)(-Δ)^{s}u+V(x)u=f(u)+|u|^{2^{*}_{s}-2}u \quad &\mbox{ in } \mathbb{R}^{3}, \\ u\in H^{s}(\mathbb{R}^{3}), \quad u>0 &\mbox{ in } \mathbb{R}^{3}, \end{array} \right. \end{equation*} where $\varepsilon>0$ is a small parameter, $a, b>0$ are constants, $s\in (\frac{3}{4}, 1)$, $2^{*}_{s}=\frac{6}{3-2s}$ is the fractional critical exponent, $(-Δ)^{s}$ is the fractional Laplacian operator, $V$ is a positive continuous potential and $f$ is a superlinear continuous function with subcritical growth. Using penalization techniques and variational methods, we prove the existence of a family of positive solutions $u_{\varepsilon}$ which concentrates around a local minimum of $V$ as $\varepsilon\rightarrow 0$.

description: This is the second part of our series about the Higson-Roe sequence for étale groupoids. We devote this part to the proof of the universal $K$-theory surgery exact sequence which extends the seminal results of N. Higson and J. Roe to the case of transformation groupoids. In the process, we prove the expected functoriality properties as well as the Paschke-Higson duality theorem.
