description: We consider the Klein-Gordon equation on a class of Lorentzian manifolds with Cauchy surface of bounded geometry, which is shown to include examples such as exterior Kerr, Kerr-de Sitter and Kerr-Kruskal spacetimes. In this setup, we give an approximate diagonalization and a microlocal decomposition of the Cauchy evolution using a time-dependent version of the pseu-dodifferential calculus on Riemannian manifolds of bounded geometry. We apply this result to construct all pure regular Hadamard states (and associated Feynman inverses), where regular refers to the state's two-point function having Cauchy data given by pseudodifferential operators. This allows us to conclude that there is a one-parameter family of elliptic pseudodifferential operators that encodes both the choice of (pure, regular) Hadamard state and the underlying spacetime metric.

description: We test the imprint of f(R) modified gravity on the halo mass function, using N-body simulations and a theoretical model developed in (Kopp et al. 2013). We find a very good agreement between theory and simulations. We extend the theoretical model to the conditional mass function and apply it to the prediction of the linear halo bias in f(R) gravity. Using the halo model we obtain a prediction for the non-linear matter power spectrum accurate to ~10% at z=0 and up to k=2h/Mpc. We also study halo profiles for the f(R) models and find a deviation from the standard general relativity result up to 40%, depending on the halo masses and redshift. This has not been pointed out in previous analysis. Finally we study the number density and profiles of voids identified in these f(R) N-body simulations. We underline the effect of the bias and the sampling to identify voids. We find significant deviation from GR when measuring the f(R) void profiles with fR0

Form his paper we get an idea of where deep ecology might fit into anarchism, the peace movement, and economic justice. A question that arises is whether there can be a melding of these various elements that might bring unity to an ecopolitics of survival and conviviality.

To make a monster: manipulation and invention in Oscar Wilde's The picture of Dorian Gray and Italo Svevo's Senilità
Creators: name: Peterseil, Yakob
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This study attempts a comparison between two very different writers on the basis of a character who appears in both of their works. In The Picture of Dorian Gray, he is Lord Henry Wotton. In Senilità, he is Emilio Brentani. These characters represent what the Italian critic Giacomo Debenedetti saw as the domination of inner life over action. Because of this imbalance, these characters through psychological and creative manipulation convince others to become actors in their own dramas. Additionally, this study seeks to account for Debenedetti's anxiety over reading Svevo by suggesting that the critic feared these characters because they are able through imaginative means to alter the world with impunity.

description: We obtain a class of elliptic wave solutions of coupled nonlinear Helmholtz (CNLH) equations describing nonparaxial ultra-broad beam propagation in nonlinear Kerr-like media, in terms of the Jacobi elliptic functions and also discuss their limiting forms (hyperbolic solutions). Especially, we show the existence of non-trivial solitary wave profiles in the CNLH system. The effect of nonparaxiality on the speed, pulse width and amplitude of the nonlinear waves is analysed in detail. Particularly a mechanism for tuning the speed by altering the nonparaxial parameter is proposed. We also identify a novel phase-unlocking behaviour due to the presence of nonparaxial parameter.

Congressional Committee Requests Revisited: Professional Expertise, Multiple Goals and Representation
Creators: name: Faricy, Christopher George
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: House members pursue multiple goals during their legislative career. The goals of reelection, good policy making and power affect member voting and committee composition. Yet in arguably a legislator’s most important choice, committee request, only the goal of reelection has empirical support. I argue that a member utilizes all three goals when going through the committee process and requests a committee assignment that will maximize their utility across all legislative goals. Utility maximization is achieved when a member can gain influence within a policy jurisdiction through leveraging their prior expertise. I employ a multinomial logit model in examining committee requests, for eight committees over fifty years. My findings indicate that across five of the eight committees a member’s prior occupation is a strong and consistent predictor of a legislator’s request. It is plausible, given the results that members pursue multiple goals in making their request for committee assignment.

description: We present a statistical analysis of the environments of 11 supernovae (SNe) which occurred in 6 nearby galaxies (z $\lesssim$ 0.016). All galaxies were observed with MUSE, the high spatial resolution integral field spectrograph mounted to the 8m VLT UT4. These data enable us to map the full spatial extent of host galaxies up to $\sim$3 effective radii. In this way, not only can one characterise the specific host environment of each SN, one can compare their properties with stellar populations within the full range of other environments within the host. We present a method that consists of selecting all HII regions found within host galaxies from 2D extinction-corrected H$α$ emission maps. These regions are then characterised in terms of their H$α$ equivalent widths, star formation rates, and oxygen abundances. Identifying HII regions spatially coincident with SN explosion sites, we are thus able to determine where within the distributions of host galaxy e.g. metallicities and ages each SN is found, thus providing new constraints on SN progenitor properties. This initial pilot study using MUSE opens the way for a revolution in SN environment studies where we are now able to study multiple environment SN progenitor dependencies using a single instrument and single pointing.

description: We report the first magneto-caloric and calorimetric observations of a magnetic-field-induced phase transition within a superconducting state to the long-sought exotic "FFLO" superconducting state first predicted over 50 years ago. Through the combination of bulk thermodynamic calorimetric and magnetocaloric measurements in the organic superconductor $κ$ - (BEDT-TTF)$_2$Cu(NCS)$_2$, as a function of temperature, magnetic field strength, and magnetic field orientation, we establish for the first time that this field-induced first-order phase transition at the paramagnetic limit $H_p$ for traditional superconductivity is to a higher entropy superconducting phase uniquely characteristic of the FFLO state. We also establish that this high-field superconducting state displays the bulk paramagnetic ordering of spin domains required of the FFLO state. These results rule out the alternate possibility of spin-density wave (SDW) ordering in the high field superconducting phase. The phase diagram determined from our measurements --- including the observation of a phase transition into the FFLO phase at $H_p$ --- is in good agreement with recent NMR results and our own earlier tunnel-diode magnetic penetration depth experiments, but is in disagreement with the only previous calorimetric report.

description: Mapping Nearby Galaxies at Apache Point Observatory (MaNGA), one of three core programs in the Sloan Digital Sky Survey-IV (SDSS-IV), is an integral-field spectroscopic (IFS) survey of roughly 10,000 nearby galaxies. It employs dithered observations using 17 hexagonal bundles of 2 arcsec fibers to obtain resolved spectroscopy over a wide wavelength range of 3,600-10,300A. To map the internal variations within each galaxy, we need to perform accurate {\it spectral surface photometry}, which is to calibrate the specific intensity at every spatial location sampled by each individual aperture element of the integral field unit. The calibration must correct only for the flux loss due to atmospheric throughput and the instrument response, but not for losses due to the finite geometry of the fiber aperture. This requires the use of standard star measurements to strictly separate these two flux loss factors (throughput versus geometry), a difficult challenge with standard single-fiber spectroscopy techniques due to various practical limitations. Therefore, we developed a technique for spectral surface photometry using multiple small fiber-bundles targeting standard stars simultaneously with galaxy observations. We discuss the principles of our approach and how they compare to previous efforts, and we demonstrate the precision and accuracy achieved. MaNGA's relative calibration between the wavelengths of H$α$ and H$β$ has a root-mean-square (RMS) of 1.7%, while that between [NII] $λ$6583A and [OII] $λ$3727A has an RMS of 4.7%. Using extinction-corrected star formation rates and gas-phase metallicities as an illustration, this level of precision guarantees that flux calibration errors will be sub-dominant when estimating these quantities. The absolute calibration is better than 5% for more than 89% of MaNGA's wavelength range.

description: We report on the serendipitous discovery of a star-forming galaxy at redshift z=0.116 with morphological features that indicate an ongoing merger. This object exhibits two clearly separated components with significantly different colors, plus a possible tidal stream. Follow-up spectroscopy of the bluer component revealed a low star-forming activity of 0.09 M$_{\odot}$/year and a high metallicity of 12+log(O/H)=8.6. Based on comparison with mass-star-formation-rate and mass-metallicity relations, and on fitting of spectral energy distributions, we obtain a stellar mass of 3x10$^9$ M$_{\odot}$, which renders this object comparable to the Large Magellanic Cloud (LMC). Thus our finding provides a further piece of evidence of a major merger already acting on small, dwarf galaxy-like scales.

More specifically, we describe a small gold standard made of eight poems by Horace, in which each sentence is labeled manually for the sentiment using a four-value classification (positive, negative, neutral and mixed). Then, we report on how this gold standard has been used to evaluate two au- tomatic approaches for sentiment classification: one is lexicon-based and the other adopts a zero-shot transfer approach.

description: This dissertation offers a critical history of the concept of monument in the United States from the Civil War to the present day. It is premised on the assumption that understanding the discursive and material dimensions of such categories is necessary in order to recognise their historicity and capacity for change. Focusing on six key episodes across the twentieth century, the dissertation explores how various artists, architects, and memorial associations, adopted the concept of the monument to pursue specific social and political goals. It takes the architectural debates surrounding monumentality in the 1940s as a starting point and proceeds to examine five further instances in which the concept has been historically framed. These include Frederick William Sievers’s Monument to Matthew Fontaine Maury (1929), Barnett Newman’s Broken Obelisk (1963/9), Kara Walker’s Fons Americanus (2019), and the Franklin D. Roosevelt Memorial in Washington D.C. (1955-2001). A further chapter explores the status of the monument in the mid-1960s with a particular focus on how artists associated with minimalism drew upon past monument forms in their work, and the legacy of this interaction. Throughout, I consider how much analytical weight the concept of the monument actually shoulders. I address the extent to which it is beholden to past definitions and forms, and explore how the study of the monument as a conceptual construct might highlight its critical and innovative potential. At a moment when the monument has become subject to widespread polemic, these issues have become all the more crucial. Reviewing the historical record, this dissertation demonstrates how the monument has operated across multiple discourses and suggests that the concept’s authority stems largely from its polyvalence.

Stability and dispersion relations of three-dimensional solitary waves in trapped Bose-Einstein condensates

Year: 2015
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We analyse the dynamical properties of three-dimensional solitary waves in cylindrically trapped Bose-Einstein condensates. Families of solitary waves bifurcate from the planar dark soliton and include the solitonic vortex, the vortex ring and more complex structures of intersecting vortex-line known collectively as Chladni solitons. The particle-like dynamics of these guided solitary waves provides potentially profitable features for their implementation in atomtronic circuits, and play a key role in the generation of metastable loop currents. Based on the time-dependent Gross-Pitaevskii equation we calculate the dispersion relations of moving solitary waves and their modes of dynamical instability. The dispersion relations reveal a complex crossing and bifurcation scenario. For stationary structures we find that for $μ/\hbarω_\perp > 2.65$ the solitonic vortex is the only stable solitary wave. More complex Chladni solitons still have weaker instabilities than planar dark solitons and may be seen as transient structures in experiments. Fully time-dependent simulations illustrate typical decay scenarios, which may result in the generation of multiple separated solitonic vortices.

The Bottom-Light Present Day Mass Function of the Peculiar Globular Cluster NGC 6535

description: Dynamical mass calculations have suggested that the Milky Way globular cluster NGC 6535 belongs to a population of clusters with high mass-to-light ratios, possibly due to a bottom-heavy stellar initial mass function. We use published Hubble Space Telescope data to measure the present day stellar mass function of this cluster within its half-light radius and instead find that it is bottom-light, exacerbating the discrepancy between the dynamical measurement and its known stellar content. The cluster's proximity to the Milky Way bulge and its relatively strong velocity anisotropy are both reasons to be suspicious of the dynamical mass measurement, but we find that neither straightforwardly explains the sense and magnitude of the discrepancy. Although there are alternative potential explanations for the high mass-to-light ratio, such as the presence of large numbers of stellar remnants or dark matter, we find this cluster to be sufficiently perplexing that we now exclude it from a discussion of possible variations in the initial mass function. Because this was the sole known old, Milky Way cluster in the population of high dynamical mass-to-light ratio clusters, some possible explanations for the difference in cluster properties are again open for consideration.

description: The Draco nebula is a high Galactic latitude interstellar cloud likely to have been formed by the collision of a Galactic halo cloud entering the disk of the Milky Way. Such conditions are ideal to study the formation of cold and dense gas in colliding flows of warm gas. We present Herschel-SPIRE observations that reveal the fragmented structure of the interface between the infalling cloud and the Galactic layer. This front is characterized by a Rayleigh-Taylor instability structure. From the determination of the typical length of the periodic structure (2.2 pc) we estimated the gas kinematic viscosity and the turbulence dissipation scale (0.1 pc) that is compatible with that expected if ambipolar diffusion is the main mechanism of energy dissipation in the WNM. The small-scale structures of the nebula are typical of that seen in some molecular clouds. The gas density has a log-normal distribution with an average value of $10^3$ cm$^{-3}$. The size of the structures is 0.1-0.2 pc but this estimate is limited by the resolution of the observations. The mass ranges from 0.2 to 20 M$_{\odot}$ and the distribution of the more massive clumps follows a power law $dN/d\log(M) \sim M^{-1.4}$. We identify a mass-size relation with the same exponent as that found in GMCs ($M\sim L^{2.3}$) but only 15% of the mass of the cloud is in gravitationally bound structures. We conclude that the increase of pressure in the collision is strong enough to trigger the WNM-CNM transition caused by the interplay between turbulence and thermal instability as self-gravity is not dominating the dynamics.

Adaptively Directional Wireless Power Transfer for Large-scale Sensor Networks

description: Wireless power transfer (WPT) prolongs the lifetime of wireless sensor network by providing sustainable power supply to the distributed sensor nodes (SNs) via electromagnetic waves. To improve the energy transfer efficiency in a large WPT system, this paper proposes an adaptively directional WPT (AD-WPT) scheme, where the power beacons (PBs) adapt the energy beamforming strategy to SNs' locations by concentrating the transmit power on the nearby SNs within the efficient charging radius. With the aid of stochastic geometry, we derive the closed-form expressions of the distribution metrics of the aggregate received power at a typical SN and further approximate the complementary cumulative distribution function using Gamma distribution with second-order moment matching. To design the charging radius for the optimal AD-WPT operation, we exploit the tradeoff between the power intensity of the energy beams and the number of SNs to be charged. Depending on different SN task requirements, the optimal AD-WPT can maximize the average received power or the active probability of the SNs, respectively. It is shown that both the maximized average received power and the maximized sensor active probability increase with the increased deployment density and transmit power of the PBs, and decrease with the increased density of the SNs and the energy beamwidth. Finally, we show that the optimal AD-WPT can significantly improve the energy transfer efficiency compared with the traditional omnidirectional WPT.

description: The Liber Abbaci (13th century) is a milestone in the history of mathematics and ac counting. Due to the late stage of Latin, its features and its very specialized content, it also represents a unique resource for scholars working on Latin corpora. In this paper we present the annotation and linking work carried out in the frame of the project Fibonacci 1202-2021. A gold-standard lemmatization and part-of-speech tagging allow us to elaborate some first observations on the linguistic and historical features of the text, and to link the text to the Lila Knowledge Base, that has as its goal to make distributed linguistic resources for Latin interoperable by fol- lowing the principles of the Linked Data paradigm. Starting from this specific case, we discuss the importance of annotating and linking scientific and technical texts, in order to (a) compare and search them together with other (non-technical) Latin texts (b) train, apply and evaluate NLP resources on a non-standard variety of Latin. The paper also describes the fruitful interaction and coordination between NLP experts and traditional Latin scholars on a project requiring a large range of expertise.

description: We build on the evidence provided by our Legacy Survey of Galactic globular clusters (GC) to submit to a crucial test four scenarios currently entertained for the formation of multiple stellar generations in GCs. The observational constraints on multiple generations to be fulfilled are manifold, including GC specificity, ubiquity, variety, predominance, discreteness, supernova avoidance, p-capture processing, helium enrichment and mass budget. We argue that scenarios appealing to supermassive stars, fast rotating massive stars and massive interactive binaries violate in an irreparable fashion two or more among such constraints. Also the scenario appealing to AGB stars as producers of the material for next generation stars encounters severe difficulties, specifically concerning the mass budget problem and the detailed chemical composition of second generation stars. We qualitatively explore ways possibly allowing one to save the AGB scenario, specifically appealing to a possible revision of the cross section of a critical reaction rate destroying sodium, or alternatively by a more extensive exploration of the vast parameter space controlling the evolutionary behavior of AGB stellar models. Still, we cannot ensure success for these efforts and totally new scenarios may have to be invented to understand how GCs formed in the early Universe.

description: Paper is a material we know from our day-to-day lives because it is used in newspapers, tissues, packaging, etc. Its web-like structure consists of wood fibres and can be visualised by comparing it to the cooking of a portion of spaghetti that is later served onto a plate. Paper is often associated with traditional materials and production technologies. Brought to life in the second century AD, paper has had a significant role in the history of civilisations, from the Chinese empire through the Guttenberg era up to the current ‘digital age’. It has primarily been used as an information carrier and packaging material. However, the architectural applications of paper have been known since the eighth century AD. Although production technologies and the finish of paper have changed and improved over the years, paper has in fact remained remarkably the same through the centuries. It still has the same composition: cellulose fibres bonded in a wet environment, then pressed and dried. Recently, not only the paper-making industry has undergone change, but other industries, like architecture, electronics, the automotive industry and others, are also receptive to the innovative qualities of paper. Growing awareness of the scarceness of fossil fuels and natural resources, the need to curb CO2 emissions and the necessity of reducing the ecological burden caused by the use of materials such as plastics, foam, concrete or steel is encouraging people to find more environmentally friendly solutions, including the circular economy. Paper and its derivatives can satisfy these needs, although it seems that the golden age of paper is coming to an end. Electronic devices such as smartphones, tablets and e-readers, as well as the growing popularity of electronic media, have taken the place of traditional print media, which has resulted in the paper industry’s decline as the producer of information carriers. However, the paper industry can develop in other directions, e.g. smart packaging, the provision of energy and construction materials, where this renewable and cheap material can make a new start, using and being used along with new technologies and innovations. Sustainable development was first described in the Agenda21 document in 1992 and its appendices, which state that the most important challenges for global policy are improving people’s lives and conserving our natural resources in a world that is growing in population, with ever-increasing demands for food, water, shelter, sanitation, energy, health services and economic security. Moreover, the European Parliament and the Council of the European Union ordered in Directive 2008/98/EC that by 2020, the weight amount of recycled or re-used construction waste must be increased to a minimum of 70%. These challenges can be addressed by renewable resources – reusable, recyclable, available and affordable materials, among other things. One of these renewable resources is paper.

description: Paper base products such as corrugated cardboard, paper tubes, honeycomb panels and strong papers like Kraft and Washi can be successfully used for the production of interior design, products for everyday use, furniture, indoor partitions, pavilions and bigger architectural structures. Paper and its derivatives are often used for other purposes such as educational (origami) or social and artistic events. Moreover, paper and cardboard are cheap and eco-friendly materials. Therefore, are they fit to be used in spatial structures for a limited lifespan. Fairs, exhibitions, major sporting events and other short-term events cost an enormous amount of money, and in many cases leave behind an ecological burden in the form of construction waste. In 2008, under the EU’s revised Waste Framework Directive, a new target for recycling rates was established. By the year 2020 50% of municipal waste, including at least 50% of paper, metal, plastics and glass, will have to be recyclable, as well as 70% of demolition waste. The projects presented in this chapter are characterised by different size, geometry, materials and properties, as well as by different connections between these aspects. The projects were created by various designers, including the author of this thesis. In this chapter, the typology of paper and cardboard in design and architecture is described and depicted by means of realised examples. Smaller projects of the first two types are described below, in this chapter. For their part, more complicated structures, such as large pavilions, houses and public buildings, will be described in Chapter 4. Emergency and relief projects will be presented in Chapter 5.

description: The examples of paper architecture presented in this chapter show the wide variety of materials and compositions used. The chosen examples are divided into two sections. The first section, entitled ‘The History of Paper in Architecture,’ embraces the projects realised from the late nineteenth century to the late 1980s. The examples provided in the ‘Case Studies’ section were assessed more thoroughly for their function, structural system, usable area, used material, connections and details of the structure (foundation, walls, roof), impregnation and lifespan. The chosen projects represent the most interesting solutions as far as structure and use of materials are concerned. Each of the examples described in this section presented an element of novelty in the world of paper architecture.

Evaluating community art through the lens of critical citizenship: a case study exploring how community art can enable young people to become critical citizens
Creators: name: Warner, Susan
Publisher: name: Loughborough University
Year: 2023
Subjects: Political science not elsewhere classified

description: This thesis explores claims that contemporary community arts projects have the power to bring about social change and challenges existing critical frameworks that argue such projects perpetuate the status quo. I argue that this is too simplistic an assertion and that a more nuanced account of community art is required. Drawing on Paulo Freire’s concept of critical pedagogy, I propose that critical citizenship is a prerequisite for change which can capitalise on the synthesis that already exists between the processes of community art and critical pedagogy. Citizenship education in England has attempted to address the perceived problem that young people were disinterested in and thus disengaged from the political processes. However, the curriculum has been found to be lacking and, over the past ten years, it has been significantly reduced revealing a form of citizenship which promotes economic self-sufficiency, civic obedience, and voluntary action meaning there is no room for the development of critical engagement with society in schools. Thus, different opportunities are required. Therefore, I suggest that there is a synergy between these three pillars of enquiry relating to young people, community art, and critical citizenship. Following detailed engagement with the literature pertaining to these three pillars of enquiry, the focus of this thesis is a case study. Utilising the framework for critical citizenship education, developed by Laura Johnson and Paul Morris (2010) I conduct an in-depth analysis of a community art project entitled, Postcode Criminals (2011-12), based in Liverpool. Initiated by artist, Joann Kushner, the project sought to challenge the negative stereotyping of urban youth, perpetuated by the zero tolerance policing strategies employed in the city. I examine how the processes employed within the project can provide the space where young people can develop the skills necessary to become critical citizens and how the artwork produced can provide evidence of this. This thesis makes an original contribution to the debates around the role and impact of community arts. I assert that in developing an understanding of community arts projects through the lens of critical citizenship a more nuanced account of their impacts on social change can be developed. Thus, the critical citizenship framework should be added to the community artists’ toolkit.

description: Interstellar polycyclic aromatic hydrocarbons (PAHs) are strongly affected by the absorption of vacuum ultraviolet (VUV) photons in the interstellar medium (ISM), yet the branching ratio between ionization and fragmentation is poorly studied. This is crucial for the stability and charge state of PAHs in the ISM in different environments, affecting in turn the chemistry, the energy balance, and the contribution of PAHs to the extinction and emission curves. We studied the interaction of PAH cations with VUV photons in the 7-20 eV range from the synchrotron SOLEIL beamline, DESIRS. We recorded by action spectroscopy the relative intensities of photo-fragmentation and photo-ionization for a set of eight PAH cations ranging in size from 14 to 24 carbon atoms, with different structures. At photon energies below ~13.6 eV fragmentation dominates for the smaller species, while for larger species ionization is immediately competitive after the second ionization potential (IP). At higher photon energies, all species behave similarly, the ionization yield gradually increases, leveling off between 0.8 and 0.9 at ~18 eV. Among isomers, PAH structure appears to mainly affect the fragmentation cross section, but not the ionization cross section. We also measured the second IP for all species and the third IP for two of them, all are in good agreement with theoretical ones confirming that PAH cations can be further ionized in the diffuse ISM. Determining actual PAH dication abundances in the ISM will require detailed modeling. Our measured photo-ionization yields for several PAH cations provide a necessary ingredient for such models.

description: We analyse the combined effect of the radiation-pressure and cross-Kerr nonlinearity on the stationary solution of the dynamics of a nanomechanical resonator interacting with an electromagnetic cavity. Within this setup, we show how the optical bistability picture induced by the radiation-pressure force is modified by the presence of the cross-Kerr interaction term. More specifically, we show how the optically bistable region, characterising the pure radiation-pressure case, is reduced by the presence of a cross-Kerr coupling term. At the same time, the upper unstable branch is extended by the presence of a moderate cross-Kerr term, while it is reduced for larger values of the cross-Kerr coupling.

description: This part of the dissertation is dedicated to the practical approach to cardboard as a building material through prototyping. Taking a practical approach here means conducting research by design and prototyping architectural structures in which paper and its derivatives are used as the main structural material. The theoretical research and knowledge presented in the previous chapters of the dissertation will be now used as input. The research by design and the realised prototypes will guide us to the solution that answers the question to what extent cardboard can be used as a suitable building material for emergency architecture. The research and development of cardboard architecture used as input for this dissertation were derived from research previously conducted at TU Delft’s Faculty of Architecture. The Cardboard in Architecture research group, which was set up in the department of Building Technology in 2003 and ceased to exist in 2008 due to the great fire that destroyed the building of TU Delft’s Faculty of Architecture (13 May 2008), made a great contribution to this research. The fundamental and technical research was included in the previous chapters. The designs and development of products in the form of prototypes of cardboard structures are presented in this chapter.

description: The microscopic justification of the emergence of SU(3) symmetry in heavy nuclei remains an interesting problem. In the past, the pseudo-SU(3) approach has been used, with considerable success. Recent results seem to suggest that the key for understanding the emergence of SU(3) symmetry lies in the properties of the proton-neutron interaction, namely in the formation of (S=1, T=0) p-n pairs in heavy nuclei, especially when the numbers of valence protons and valence neutrons are nearly equal. Although this idea has been around for many years, since the introduction of the Federman-Pittel mechanism, it is only recently that information about the p-n interaction could be obtained from nuclear masses, which become available from modern facilities. Based on this information, a new coupling scheme for heavy deformed nuclei has been suggested and is under development.
