    Lineup polytopes of product of simplices

    Full text link
    Consider a real point configuration A\mathbf{A} of size nn and an integer r‚ȧnr \leq n. The vertices of the rr-lineup polytope of A\mathbf{A} correspond to the possible orderings of the top rr points of the configuration obtained by maximizing a linear functional. The motivation behind the study of lineup polytopes comes from the representability problem in quantum chemistry. In that context, the relevant point configurations are the vertices of hypersimplices and the integer points contained in an inflated regular simplex. The central problem consists in providing an inequality representation of lineup polytopes as efficiently as possible. In this article, we adapt the developed techniques to the quantum information theory setup. The appropriate point configurations become the vertices of products of simplices. A particular case is that of lineup polytopes of cubes, which form a type BB analog of hypersimplices, where the symmetric group of type~AA naturally acts. To obtain the inequalities, we center our attention on the combinatorics and the symmetry of products of simplices to obtain an algorithmic solution. Along the way, we establish relationships between lineup polytopes of products of simplices with the Gale order, standard Young tableaux, and the Resonance arrangement.Comment: 19 pages, 8 figure

    Improving the census of open clusters in the Milky Way with data from Gaia

    For over a century, open clusters have been a key tool for understanding stellar and galactic evolution. Now, thanks to groundbreaking new astrometric and photometric data from the European Space Agency's Gaia satellite, it is possible to study open clusters to never before seen levels of accuracy and precision. In this thesis, I develop and apply new methodologies to improve the census of open clusters with data from Gaia. I focus on using modern, efficient, and statistically rigorous techniques, aiming to maximise the reliability and usefulness of the open cluster census despite the many challenges of working with the billion-star dataset of Gaia. Firstly, I conducted a comparative study of clustering algorithms for retrieving open clusters blindly from Gaia data. I found that a previously untrialed algorithm, HDBSCAN, is the most sensitive algorithm for open cluster recovery. Next, using this methodology, I used Gaia DR3 data to create the largest homogeneous catalogue of open clusters to date, recovering a total of 7167 clusters -- 2387 of which are candidate new objects. I developed an approximate Bayesian neural network for classifying the reliability of the colour-magnitude diagrams of the clusters in the census. Additionally, I used a modification of this network to infer parameters such as the age and extinction of these clusters. Finally, since many of the objects in my catalogue appeared more compatible with moving groups, I measured accurate masses, Jacobi radii, and velocity dispersions for these clusters, thus creating the largest catalogue of these parameters for open clusters to date. Using said parameters, I showed that no more than 5619 of the clusters in my catalogue are compatible with bound open clusters. I used my mass estimates to derive an approximate completeness estimate for the Gaia DR3 open cluster census, finding that the approximate 100% completeness limit depends strongly on cluster mass. The results of this thesis show that it is possible to reliably create a catalogue of open clusters with a single blind search, in addition to measuring parameters for these objects. The methods developed in this thesis will be applicable to future data releases from Gaia and other sources

    Towards a sustainable PV waste policy: Exploring the management practices of end-of-life solar photovoltaic modules in Australia

    Get PDF
    Solar photovoltaic (PV) systems are effective measures to reduce the greenhouse gas emissions. However, the large exploitation of solar PV modules, leads to undesirable waste accumulation, affecting the environment. Solar PV waste management research is an emerging field that has received more attention recently, affected by the increase volume of solar PV disposals. However, only a few studies have examined the current practices in solar photovoltaic waste management. In Australia, because of social and economic factors (such as the replacement of small-scale PV systems come with new rebates), residential solar systems are decommissioned earlier than expected before reaching their end-of-life (EoL). 70% of the market share of PV systems are predominately dominated by the residential market in Australia as of 2020. The average practical lifetime of PV modules instead of 20-30 years is 15-20 years in Australia. Therefore, the volume of EoL PV from the residential sector entering the waste stream in the coming decade will be higher than previously predicted. This study aims to assess the environmental impacts of waste from rooftop solar photovoltaic panels in Australia to inform sustainable policies. To achieve the aim of the research, the following objectives are investigated: 1) exploring the current practices of managing end-oflife rooftop solar photovoltaic panels in Australia; 2) developing an optimised system approach in dealing with solar photovoltaic waste in Australia; and 3) assessing the environmental impacts of end-of-life rooftop solar photovoltaic panels in Australia within the developed assessment framework. To achieve the research objectives, several methods are adopted to analyse the primary and secondary data for this research. A modified Fuzzy Delphi Method (FDM) is adopted in gathering data through interviews and questionnaires from experts in the field. The results show that, crystalline silicon panels were the most common panels on the Australian market and the ones that are being installed frequently. On policies, although the Australian government has banned PV waste from going to landfill since 2014, there were no regulations or action plans to manage PV waste. The absence of policies and regulations results in unregulated movement and tracking of solar PV waste in and out of Australia as well as within and across the states. The extent of the PV recovery and recycling warrants further investigation. Moreover, infrastructure and logistics has been a significant problem because of the geographical spread of the country and how it affects transportation and the supply chain. Findings led to the establishment of a conceptual framework for the current treatment of solar PV waste in Australia. Furthermore, a Weibull distribution model is employed to forecast the PV waste in the next three decades in South Australia. The study further estimates the pollutant emission associated with the collection and transportation of the waste for recycling and recovery. Results indicate that, there will be 109,007 tons of PV waste generated in urban and suburban context in South Australia by 2050. Among the three routing scenarios generated, the third scenario with optimised transfer stations and an additional recycling facility showed more than 34% reduction in pollutant emission. This study evaluates the environmental impacts of three policy options for mono and multi crystalline silicon (c-Si) solar panel waste modules. The impact of transport distance from transfer stations to the recycling centre is also assessed. The life cycle assessment revealed that, -1E+06 kgCO2eq and -2E+06 kgCO2eq are associated with the mandatory product stewardship scenarios under global warming potential for mono and multi c-Si solar modules respectively. However, the non-existence of a product stewardship will produce a global warming impact of 1E+05 kgCO2eq for both modules. The global warming effects revealed that, collecting and recycling most of the multi c-Si panels were not effective (-365 kg CO2-eq, -698.4 kg CO2-eq, -1032 kg CO2-eq) compared to keeping them away from the landfills and fully recycling (- 2E+06 kg CO2-eq) them. It was also highlighted that, the highest environmental impact regarding the transport distances was the scenario of one recycling centre serving over 107 transfer stations with a global warming potential of 1E+06 kgCO2eq. In conclusion, this study contributes to the management of the supply market of solar PV technologies, using Australia as a case study. The recommendations derived from the study include: creating collection centres for EoL PV modules in South Australia, developing a logistic network to for the collection of EoL PV modules, creating and enhancing the PV recycling market for recovered materials, issuing a regulatory landfill ban for EoL solar PV module in South Australia, developing a mandatory product stewardship for PV waste in Australia, promoting and providing financial incentives to current and future infrastructure for PV recycling, minimising the exportation of PV waste overseas and interstate, encouraging industry led research on new innovations to improve the recovery of different PV technology families, developing sustainable measures to cut emissions for recycling through research and development in South Australia, and building the capacity and promoting awareness on the benefits of PV recycling in South Australia.Thesis (Ph.D.) -- University of Adelaide, School of Architecture and Civil Engineering, 202

    The application of engineering measurement and three-dimensional (3D) computer aided engineering techniques to the study of medieval period European swords

    Get PDF
    This thesis details the programme of research undertaken by the author to investigate the use of engineering measurement and computer-aided engineering techniques for the modelling and analysis of medieval period ‚Äėknightly‚Äô swords. The sword has an iconic cultural status that transcends its primary purpose as a tool of war, featuring frequently and extensively in art and literature from early human mythology through to contemporary film and digital media. In Europe, the sword was arguably at its most influential, both practically and culturally, during the mid-late medieval period, and yet there has been limited understanding and a misinformed mythology around the iconic knightly sword that proliferated during this period. A resurgent interest, and associated research, in historical European martial arts has started to address this gap in understanding, and the use of engineering measurement and analysis techniques to inform historical research has been growing more generally in recent years. There is a clear benefit that such techniques can bring to create a more complete picture of historical artefacts in terms of their design, construction, and performance, and that was the focus of this research programme. Of course, surviving medieval swords are, relatively speaking, rare, valuable, and often fragile, and these factors presented some specific challenges when trying to access and study them. The original contribution of this work has been to overcome these challenges to develop and demonstrate a robust methodology for creating and analysing 3-dimensional models that accurately recreate the geometry and mass properties of historical artefacts. During the programme, consideration has been given to accuracy, repeatability, ease of acquisition and the constraints associated with this type of artefact, such that the methodology might be used beyond this specific programme of work. Having created these digital models, specific features have been analysed and simulated, and this approach has been applied to eight original medieval swords, providing new and interesting insights into their features, design, and original performance characteristics

    Ruokajärjestelmiä pyritään kehittämään kestävimmiksi muun muassa reaktiona etenevään luontokatoon ja ilmastonmuutokseen. Ruokajärjestelmien kestävyyteen on yhdistetty esimerkiksi lähiruoan käyttö, luomutuotanto ja kiertotalous, joihin keskityn tässä väitöskirjatutkimuksessa. Tarkastelen näitä teemoja Suomen alueiden, aluekehityksen ja aluetalouksien näkökulmasta lisäämällä ymmärrystä, miten alueiden ominaisuudet ja resurssit vaikuttavat ruokajärjestelmien kestävyyssiirtymään sekä vastaavasti miten ruokajärjestelmien kestävyyssiirtymä vaikuttaa aluetalouksiin. Jotta aihetta voidaan tarkastella mahdollisimman monipuolisesti, tutkimuksessa hyödynnetään systeemiajattelua sekä useita menetelmiä ja aineistoja: muun muassa kvalitatiivista vertailevaa analyysiä (QCA), yleisen tasapainon mallinnusta (CGE), kyselyitä julkiskeittiöille sekä luomutuottajille, tilastoja sekä kirjallisuutta. Tutkimuskokonaisuus onkin luonteeltaan osin määrällistä sekä osin määrällisen ja laadullisen lähestymistavan rajapinnassa olevaa tarkastelua. Tulosten perusteella alueiden sekä ruokajärjestelmien ominaisuudet ja niissä tapahtuvat muutokset heijastuvat toisiinsa. Alueiden sosioekonomiset tekijät kuten hankintarenkaiden ja -yksiköiden organisaatiorakenne ja resurssit, ruokajärjestelmien toiminnan piirteet esimerkiksi pitkä perinne koulutus- ja edistämistoimissa sekä biofysikaaliset ominaisuudet kuten agroekologiset olosuhteet vaikuttavat alueen toimijoiden mahdollisuuksiin siirtyä kestävyyteen yhdistettyihin tuotanto- ja kulutustapoihin, kuten luomutuotantoon ja lähiruoan käyttöön. Toisin sanoen alueellisen ruokajärjestelmän toimijoiden ja toiminnan lisäksi alueen sosioekonominen ja poliittinen ympäristö sekä luonnonympäristö vaikuttavat ruokajärjestelmän muutokseen. Vastaavasti ruokajärjestelmien kestävyyssiirtymä vaikuttaa alueisiin ja aluetalouksiin. Tulosten perusteella ruokajärjestelmien kestävyyssiirtymän vaikutus voi olla aluetalouksia monipuolistava ja aluetalouksien kasvua edistävä, minkä lisäksi alueelliset erot näkyvät myös kestävyyssiirtymän aluetaloudellisten vaikutusten laajuudessa. Ruokajärjestelmien uudistaminen kestävyystavoitteiden mukaisesti voi edistää myös alueellista oikeudenmukaisuutta, sillä tutkimani agroekologiseen symbioosimalliin perustuva kestävyyssiirtymä tarjoaa talous- ja työllisyysmahdollisuuksia etenkin maaseutualueille tasoittaen siten maaseutualueiden ja kaupunkien välisiä taloudellisia eroja. Kaiken kaikkiaan ruokajärjestelmien kestävyyssiirtymä edellyttää alueelliset erilaisuudet huomioivaa paikkaperustaista kehittämistä sekä toimijoiden välistä yhteistyötä.Several efforts have been made to develop more sustainable food systems withstanding changes like progressive nature loss and climate change. For example, local food, organic farming, and a circular economy have been connected to food system sustainability, which I concentrate on in this thesis. I study these themes from the viewpoint of Finnish regions, regional development, and regional economies by increasing understanding of the impacts of regional features and resources on food system sustainability, and correspondingly, the impacts of a food system sustainability transition on regional economies. To achieve the most versatile examination of this subject, I use the systems approach in this research along with several methods and materials: qualitative comparative analysis (QCA), computable general equilibrium modelling (CGE), surveys of public kitchens and organic farmers, statistics, and literature, for example. Thus, this research can be defined as partly quantitative and partly at the interface of quantitative and qualitative. According to the results, regional and food system features and the changes in them reflect each other. Each region’s socioeconomic factors such as organizational structure and resources of public joint procurement groups and procuring entities, features of food system operation like long traditions in education and promotion activities, and biophysical properties such as agroecological conditions affect the opportunities of actors in the region to convert to sustainability-related production and consumption methods, such as organic farming and local food use. In other words, in addition to the actors and operations in regional food systems, the socioeconomical, political, and natural environment affect the change in food systems. Respectively, the sustainability transition of food systems affects regions and regional economies. Based on the results, the effect of the sustainability transition of food systems can diversify and promote the growth of regional economies, and regional differences can be seen in the extent of the regional economic effects of the transition to sustainability. Renewing food systems in accordance with sustainability goals can also promote regional justice, as a sustainability transition based on the studied agroecological symbiosis model offers economic and employment opportunities particularly to rural areas, thus narrowing the economic differences between rural and urban areas. Overall, the sustainability transition of food systems requires place-based development that accounts for regional differences and cooperation between actors.fi=vertaisarvioitu|en=peerReviewed
