Abstract:

Motivated by Gage [On an area-preserving evolution equation for plane curves, in Nonlinear Problems in Geometry, ed. D. M. DeTurck, Contemporary Mathematics, Vol. 51 (American Mathematical Society, Providence, RI, 1986), pp. 51–62] and Ma–Cheng [A non-local area preserving curve flow, preprint (2009), arXiv:0907.1430v2, [math.DG]], in this paper, an area-preserving flow for convex plane curves is presented. This flow will decrease the perimeter of the evolving curve and make the curve more and more circular during the evolution process. And finally, as t goes to infinity, the limiting curve will be a finite circle in the C∞ metric.

Abstract:

The following paper focuses on the transitional period between the Middle Bronze Age (MBA) and the Late Bronze Age (LBA) in the Southern Urals, Russia. GIS-based analysis of Bronze Age settlement patterns in the Kyzil Area points to a number of important findings. The study concludes the demographic impossibility of an autonomous development scenario of the Sintashta – Srubnaya-Alakul cultural transformation, rejects the presence of ‘proto-city’ or urbanization developments in the region during the Bronze Age, and points to the shift to a more collective form of control over natural resources during the LBA period. The study also examines the spatial distribution of ‘kurgan’ cemeteries in the area. Among other things, this thesis illustrates how settlement pattern studies can add to and complement the heavily burial data - driven research, often relied upon in the archaeological analysis of the Eurasian Steppes.

Abstract:

Der Beitrag beschreibt die Voraussetzungen des gelungenen Strukturwandels mit der Bündelung der Potentiale von Bodenschätzen, Geographie, Wirtschaft und Bevölkerung. Das Ruhrrevier in seiner heutigen Form ist im besonderen Maße Ausdruck der montanindustriellen Entwicklung. Diese wiederum hängt maßgeblich von der Ausbildung der Steinkohlenlagerstätte ab. So sind es die geologischen Schichten der Region, die diese nachhaltig gestaltet haben. Die Steinkohlenlagerstätte des Ruhrreviers entwickelte sich bereits vor über 300 Mio. Jahren unter subtropischen Bedingungen. Meeresnahe Ablagerungen sind Ursprung des „schwarzen Goldes“, der Steinkohle zwischen Ruhr und Lippe. Eine wechselvolle Geschichte führt über Gebirgsbildungen, Fort- und Rückschreitung der Küstenlinie sowie eiszeitlicher und fluviatiler Sedimentationen zur Gestaltung von Geologie und Morphologie im Ruhrrevier. Die heutige Raumstruktur des Ruhrgebiets entstand somit aus der Geomorphologie des Karbons mit den sich herausgebildeten Flüssen Ruhr, Emscher und Lippe und den sich daran orientierenden mittelalterlichen Städten und Siedlungen. Mit den Auswirkungen der industriellen Revolution auf Basis Kohle, Eisen und Stahl veränderte sich die Region von einem landwirtschaftlich geprägten Raum hin zum heutigen Ballungsraum mit über 5 Millionen Einwohnern. Von den ehemals über 400 Zechen im Ruhrrevier existierten im Jahr 2015 noch zwei fördernde Bergwerke. Das Bergwerk Auguste Victoria wurde Ende 2015 eingestellt, das Bergwerk Prosper Haniel wird Ende 2018 die Förderung einstellen. Damit endet der subventionierte Steinkohlebergbau in Deutschland aus ökonomischen Gründen. Die Lagerstätte im Ruhrrevier ist jedoch bei weitem noch nicht erschöpft. Die Beendigung des Bergbaues führte zu einem Strukturwandel, der in den 1960er Jahren begann und heute noch nicht sein Ende gefunden hat. Er hat eine industrielle, stabile Raumstruktur mit neuem Leben zu füllen. Zwischen Ruhr und Lippe sowie am Niederrhein haben 53 eigenständige Städte und Gemeinde das historische Erbe aufzunehmen und gemeinsam die regionalen Stärken zu fördern. Die großen Flächenstilllegungen wurdenin den prosperierenden Zonen zu modernen Stadtquartieren mit unterschiedlichsten Nutzungen entwickelt oder haben in den Zwischenräume die Landschaften und Freizeitgebiete vergrößert
The article describes the prerequisites for a successful structural change in the Ruhr area during the last 60 years. Via the regional bundling of the potential in raw materials, geography, economy and population the region managed the termination of the coal and steel industry. More than 50 communities have to deal with the historic legacy and they have to promote the local features. The cessation of the intensive coal-mining phase requires creative ideas, intensive communication, coordination of a lot of stakeholders to ensure a development in the direction of new stable structures

Abstract:

This research focuses on the utilization of occlusion culling for the real-time visualization of distributed virtual urban environments. Today'
s graphics hardware renders all the primitives in any order and uses z-buffer to determine which primitives are visible on a per-pixel basis. However, visibility is computed in the last stage of rendering pipeline and every rendered primitive is not visible in the final image. Early culling of the invisible primitives in a complex scene is valuable for efficiency in the conventional rendering pipeline. This may reduce the number of primitives that will be processed in the rest of the pipeline. In this thesis, we propose an efficient visibility estimation method for distributed virtual urban environments. The proposed method is based on occlusion culling to identify and cull the occluded parts of the scene. This not only computes conservative potential visible set (PVS) for each client but also assures the computed PVS to be available at the client on-time and reduces the network traffic by grouping the clients which may see each others dynamically.

Resumo: : Esta dissertação descreve o desenvolvimento de um modelo para se avaliar áreas vulneráveis a ocorrência de erosão através de uma combinação de 3 variáveis: uso e ocupação do solo, declividade e mapa geológico. Para cada um dos atributos referente as variáveis escolhidas foram atribuídos pesos em potências de 2 gerando 72 combinações, sendo reclassificadas em 4 classes: pouco vulnerável, vulnerável, muito vulnerável e alto risco. Foi possível montar um diagnóstico entre as classes de ocupação e sua susceptibilidade à erosão observando a maior ocorrencia de cada uma e se estas ocorriam simultaneamente, o que somente um SIG pode responder. Os resultados foram satisfatórios, pois um mapa previsional de risco a processos erosivos foi gerado, sendo que a base digital geo-referenciada criada pode atender a outros objetivos em diferentes áreas do conhecimento científico. ...Observação: O resumo, na íntegra, poderá ser visualizado no texto completo da tese digital
Abstract: This dissertation describes a methodological approach to evaluate vulnerable areas to erosional processes using a combinstion of three maps: soil use, slope and geological map. Each attribute was reclassified to power of two generating 72 new categories, being reclassified again in to 4 categories: low vulnerability, vulnerable, high vulnerability and hight risk. . The comparison betwen the soil use and erosional vulnerability was carried out using GIS copabilities. The achieved results were considered satísfactory and the objetives of this thesis were reached because a suitable mapa representing areas with vulnerability to erosivel process was generated. An important characteristic of this dissertation is that the digital georeferenced database created can be use for different purposes. ...Note: The complete abstract is available with the full electronic digital thesis or dissertations

Abstract:

La presente tesis aborda problemas de optimización y obtención de desigualdades óptimas dentro de la Geometría Convexa. En concreto, se recogen las propiedades conocidas del anillo mínimo asociado a un cuerpo convexo plano y se estudian algunas propiedades nuevas que ayudan a conocer mejor la relación entre ambos. Se estudian con detalle las desigualdades geométricas existentes entre el anillo mínimo de un cuerpo convexo y las magnitudes geométricas clásicas, a saber, área, perímetro, circunradio, inradio, anchura mínima y diámetro, obteniendo en cada caso los conjuntos extremales. Se estudian con detalle propiedades que relacionan el anillo mínimo de un cuerpo convexo con su circunradio por un lado, y su inradio por otros. Se consideran fijos anillo mínimo y circunradio y se presentan las desigualdades óptimas que realcionan estas magnitudes con las restantes, describiendo los conjuntos extremales. Finalmente se realiza algo similar pero considerando fijos, esta vez, el anillo mínimo y el inradio.
This thesis aims to deal with the optimization problems and how to obtain the optimal inequalities within the Convex Geometry. It aims to treat with the already known properties of the minimal annulus associated to a plane convex body; we are also to study some new properties that help us know the relationship between both of them. The geometrical inequalities existing between the minimal annulus of a convex body and the classical geometrical measures are studied in detail. These measures are the area, the perimeter, the circumradius, the inradius, the minimal width and the diameter, and we will obtain in each case the extremal sets. We will study in detail those properties relating the minimal annulus of a convex body with its circumradius first and its inradius later. We will consider as fixed the minimal annulus and the cicumradius, and the optimal inequalities that relate those measures with the remaining one will be represented by describing the extremal sets. Finally, we will do something similar but considering as fixed the minimal annulus and the inradius.

Abstract:

Hypertension is a global disease that many effected people in developing countries is not aware of. Hypertension is linked with cardiovascular disease. Prehypertension is not a disease but if not correctly treated, it could develop into hypertension. The aim of the study was to investigate if there are any differences in circadian blood pressure between two study groups, one group with normal blood pressure and one group with prehypertension. This study was a explorative study and its design is based on measurements of blood pressure values and a questionnaire was used to help get the data collection. 51 students volunteered to have their blood pressure taken from them and out of these 51, 24 where selected into two groups of 12 each for the Ambulatory blood pressure monitoring. hese 24 students would be a part of our study and an ambulatory (Schiller-102 plus) blood pressure monitor was used to collect the data. The prevalence of prehypertension findings in the clinical testing phase was 37% of the population. There was a variation between the groups during the day (systolic) but there was not a significant difference during the night.

Abstract:

AbstractOne of the growing innovations in the electric vehicle market concerns light electric vehicles (LEVs), promoted at local and national level by many initiatives, such as the European project ELVITEN, involving six cities, which is analysed in the present paper in relation to the Genoa pilot case study. In Italy, LEVs have been increasingly successful, as the number of their registrations shows (+76% in 2019 compared to 2018). In this context, the city of Genoa, where a considerable fleet of mopeds and motorcycles (214,499 in its metropolitan area in 2018) circulates, lends itself well to the experimentation of two-wheeled LEVs. The monitoring of the use of LEVs within the framework of the ELVITEN project has shown that the average daily round trips recorded in the metropolitan area of Genoa are equal to 15–20 km, thus reinforcing the idea that LEVs represent a valid alternative to Internal Combustion Engine (ICE) private vehicles. Moreover, the characteristics of the travel monitored and the users’ feedback highlight that the question of range anxiety is less present than expected. Finally, and contrary to our expectations, the data analysis indicates that the use of LEVs in Genoa during two months of Covid-19 pandemic lockdown—March and April 2020—shows a decrease of 21%, while the average decrease recorded by the six cities globally considered is 51%.

Abstract:

Oxon Run Parkway (OXRN) is a 51-hectare (126-acre) natural area within Washington, D.C. administered by the National Park Service under National Capital Parks East (NACE). The original plan called for a road, slated to follow Oxon Run stream, but this never came to fruition; despite this, the moniker stuck. The majority of the original Oxon Run Parkway is managed by the District of Columbia. The section of Oxon Run Parkway under NPS jurisdiction contains wetlands and forests, as well as the only McAteean magnolia bogs still remaining in the District. The lower Cretaceous Potomac Group, known as one of the few dinosaur-bearing rock units on the east coast of North America, crops out within Oxon Run. One of the most prevalent fossil-bearing resources are the siderite, or “bog iron” sandstone slabs that sometimes preserve the footprints or trackways of various vertebrates, including dinosaurs. Such trackways have been reported from Potomac Group outcrops throughout the Atlantic Coastal Plain of Maryland and Virginia. In 2019, National Capital Parks-East took possession of such a track, referred to a dinosaur, collected by paleontologist Dr. Peter Kranz. This report was compiled after a paleontological survey of Oxon Run Parkway and is intended as a supplement to the National Capital Parks East Paleontological Resource Inventory (Nelson et al. 2019). This report contains information on the history of Oxon Run Parkway and its geology, as well as discussion of the fossil track.

Abstract:

The Northwest Tropical Atlantic Station (NTAS) was established to address the need for accurate air-sea flux estimates and upper ocean measurements in a region with strong sea surface temperature anomalies and the likelihood of significant local air–sea interaction on interannual to decadal timescales. The approach is to maintain a surface mooring outfitted for meteorological and oceanographic measurements at a site near 15°N, 51°W by successive mooring turnarounds. These observations will be used to investigate air–sea interaction processes related to climate variability. This report documents recovery of the NTAS-18 mooring and deployment of the NTAS-19 mooring at the same site. Both moorings used Surlyn foam buoys as the surface element. These buoys were outfitted with two Air–Sea Interaction Meteorology (ASIMET) systems. Each system measures, records, and transmits via Argos satellite the surface meteorological variables necessary to compute air–sea fluxes of heat, moisture and momentum. The upper 160 m of the mooring line were outfitted with oceanographic sensors for the measurement of temperature, salinity and velocity. Deep ocean temperature and salinity are measured at approximately 38 m above the bottom. The mooring turnaround was done on the National Oceanic and Atmospheric Administration (NOAA) Ship Ronald H. Brown, Cruise RB-20-06, by the Upper Ocean Processes Group of the Woods Hole Oceanographic Institution. The cruise took place between 14 October and 1 November 2020. The NTAS-19 mooring was deployed on 22 October, with an anchor position of about 14° 49.48° N, 51° 00.96° W in 4985 m of water. A 31-hour intercomparison period followed, during which satellite telemetry data from the NTAS-19 buoy and the ship’s meteorological sensors were monitored. The NTAS-18 buoy, which had gone adrift on 28 April 2020, was recovered on 20 October near 13° 41.96° N, 58° 38.67° W. This report describes these operations, as well as other work done on the cruise and some of the pre-cruise buoy preparations.

Abstract:

Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the cover and frequency of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2008, 2011, 2015, and 2019, Heartland Network staff and contractors identified a cumulative total of 51 potentially problematic plant species in Hopewell Culture National Historical Park. Of the 37 species found in 2019, we characterized 7 as very low frequency, 9 as low frequency, 17 as medium frequency, and 4 as high frequency. Of these, midpoint cover estimates of 2 medium frequency and 2 high frequency species exceeded the 10-acre threshold. Because of the number, extent, and cover of problematic plants in the park and the small park size, control efforts should focus on treating high priority species across the entire park. High priority species may include plant species capable of rapid spread, species at low population levels, and species which can effectively be controlled.

Abstract:

The project “Social network tools and procedures for developing entrepreneurial skills in PhD programmes” (prodPhD) aims to implement innovative social network-based methodologies for teaching and learning entrepreneurship in PhD programmes. The multidisciplinary teaching and learning methodologies to be developed will enable entrepreneurship education to be introduced into any PhD programme, providing students with the knowledge, skills, and motivation to engage in entrepreneurial activities. However, the use of the output of the project will depend on the nature and profile of the research or scientific field. In this context, key performance indicators (KPIs) form the base on which the quality and scope of the methodologies developed in the project will be quantified and benchmarked. The project’s final product will be an online tool that higher education students can use to learn entrepreneurship from a social network perspective. Performance measurement is one of the first steps of any project and involves the choice and use of indicators to measure the effectiveness and success of the project’s methods and results. All the KPIs have been selected according to criteria of relevance, measurability, reliability, and adequacy, and they cover the process, dissemination methods, and overall quality of the project. In this document, each KPI is defined together with the units and instruments for measuring it. In the case of qualitative KPIs, five-level Likert scales are defined to improve indicator measurability and reliability. The KPIs for prodPhD are divided into three main dimensions, depending on the stage of the project they evaluate. The three main dimensions are performance and development (which are highly related to the project’s process), dissemination and impact (which are more closely correlated with the project’s output), and overall project quality. Different sources (i.e., European projects and papers) have been drawn upon to define a set of 51 KPIs classified into six categories, according to the project phase they aim to evaluate. An Excel tool has been developed that collects all the KPIs analysed in the production of this document. This tool is shared in the Scipedia repository.

Abstract:

Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Key Informants. We searched MEDLINE and EMBASE (via EMBASE.com), In-Process MEDLINE and PubMed unique content (via PubMed.gov), and the Cochrane Database of Systematic Reviews for systematic reviews or controlled trials. We also searched ClinicalTrials.gov for ongoing studies. We assessed risk of bias and extracted data on health outcomes, surrogate outcomes, usability, sustainability, cost-effectiveness outcomes (quantifying the tradeoffs between health effects and cost), process outcomes, and other characteristics related to PGHD technologies. For isolated effects on health outcomes, we classified the results in one of four categories: (1) likely no effect, (2) unclear, (3) possible positive effect, or (4) likely positive effect. When we categorized the data as “unclear” based solely on health outcomes, we then examined and classified surrogate outcomes for that particular clinical condition. Findings. We identified 114 unique studies that met inclusion criteria. The largest number of studies addressed patients with hypertension (51 studies) and obesity (43 studies). Eighty-four trials used a single PGHD device, 23 used 2 PGHD devices, and the other 7 used 3 or more PGHD devices. Pedometers, blood pressure (BP) monitors, and scales were commonly used in the same studies. Overall, we found a “possible positive effect” of PGHD interventions on health outcomes for coronary artery disease, heart failure, and asthma. For obesity, we rated the health outcomes as unclear, and the surrogate outcomes (body mass index/weight) as likely no effect. For hypertension, we rated the health outcomes as unclear, and the surrogate outcomes (systolic BP/diastolic BP) as possible positive effect. For cardiac arrhythmias or conduction abnormalities we rated the health outcomes as unclear and the surrogate outcome (time to arrhythmia detection) as likely positive effect. The findings were “unclear” regarding PGHD interventions for diabetes prevention, sleep apnea, stroke, Parkinson’s disease, and chronic obstructive pulmonary disease. Most studies did not report harms related to PGHD interventions; the relatively few harms reported were minor and transient, with event rates usually comparable to harms in the control groups. Few studies reported cost-effectiveness analyses, and only for PGHD interventions for hypertension, coronary artery disease, and chronic obstructive pulmonary disease; the findings were variable across different chronic conditions and devices. Patient adherence to PGHD interventions was highly variable across studies, but patient acceptance/satisfaction and usability was generally fair to good. However, device engineers independently evaluated consumer wearable and handheld BP monitors and considered the user experience to be poor, while their assessment of smartphone-based electrocardiogram monitors found the user experience to be good. Student volunteers involved in device usability testing of the Weight Watchers Online app found it well-designed and relatively easy to use. Implications. Multiple randomized controlled trials (RCTs) have evaluated some PGHD technologies (e.g., pedometers, scales, BP monitors), particularly for obesity and hypertension, but health outcomes were generally underreported. We found evidence suggesting a possible positive effect of PGHD interventions on health outcomes for four chronic conditions. Lack of reporting of health outcomes and insufficient statistical power to assess these outcomes were the main reasons for “unclear” ratings. The majority of studies on PGHD technologies still focus on non-health-related outcomes. Future RCTs should focus on measurement of health outcomes. Furthermore, future RCTs should be designed to isolate the effect of the PGHD intervention from other components in a multicomponent intervention.

Abstract:

Emergency Relief (ER) is a Department of Social Services (DSS) funded program, delivered by 197 community organisations (ER Providers) across Australia, to assist people facing a financial crisis with financial/material aid and referrals to other support programs. ER has been playing this important role in Australian communities since 1979. Without ER, more people living in Australia who experience a financial crisis might face further harm such as crippling debt or homelessness. The Emergency Relief National Coordination Group (NCG) was established in April 2020 at the start of the COVID-19 pandemic to advise the Minister for Families and Social Services on the implementation of ER. To inform its advice to the Minister, the NCG partnered with the Institute for Governance at the University of Canberra to conduct research to understand the issues and challenges faced by ER Providers and Service Users in local contexts across Australia. The research involved a desktop review of the existing literature on ER service provision, a large survey which all Commonwealth ER Providers were invited to participate in (and 122 responses were received), interviews with a purposive sample of 18 ER Providers, and the development of a program logic and theory of change for the Commonwealth ER program to assess progress. The surveys and interviews focussed on ER Provider perceptions of the strengths, weaknesses, future challenges, and areas of improvement for current ER provision. The trend of increasing case complexity, the effectiveness of ER service delivery models in achieving outcomes for Service Users, and the significance of volunteering in the sector were investigated. Separately, an evaluation of the performance of the NCG was conducted and a summary of the evaluation is provided as an appendix to this report. Several themes emerged from the review of the existing literature such as service delivery shortcomings in dealing with case complexity, the effectiveness of case management, and repeat requests for service. Interviews with ER workers and Service Users found that an uplift in workforce capability was required to deal with increasing case complexity, leading to recommendations for more training and service standards. Several service evaluations found that ER delivered with case management led to high Service User satisfaction, played an integral role in transforming the lives of people with complex needs, and lowered repeat requests for service. A large longitudinal quantitative study revealed that more time spent with participants substantially decreased the number of repeat requests for service; and, given that repeat requests for service can be an indicator of entrenched poverty, not accessing further services is likely to suggest improvement. The interviews identified the main strengths of ER to be the rapid response and flexible use of funds to stabilise crisis situations and connect people to other supports through strong local networks. Service Users trusted the system because of these strengths, and ER was often an access point to holistic support. There were three main weaknesses identified. First, funding contracts were too short and did not cover the full costs of the program—in particular, case management for complex cases. Second, many Service Users were dependent on ER which was inconsistent with the definition and intent of the program. Third, there was inconsistency in the level of service received by Service Users in different geographic locations. These weaknesses can be improved upon with a joined-up approach featuring co-design and collaborative governance, leading to the successful commissioning of social services. The survey confirmed that volunteers were significant for ER, making up 92% of all workers and 51% of all hours worked in respondent ER programs. Of the 122 respondents, volunteers amounted to 554 full-time equivalents, a contribution valued at $39.4 million. In total there were 8,316 volunteers working in the 122 respondent ER programs. The sector can support and upskill these volunteers (and employees in addition) by developing scalable training solutions such as online training modules, updating ER service standards, and engaging in collaborative learning arrangements where large and small ER Providers share resources. More engagement with peak bodies such as Volunteering Australia might also assist the sector to improve the focus on volunteer engagement. Integrated services achieve better outcomes for complex ER cases—97% of survey respondents either agreed or strongly agreed this was the case. The research identified the dimensions of service integration most relevant to ER Providers to be case management, referrals, the breadth of services offered internally, co-location with interrelated service providers, an established network of support, workforce capability, and Service User engagement. Providers can individually focus on increasing the level of service integration for their ER program to improve their ability to deal with complex cases, which are clearly on the rise. At the system level, a more joined-up approach can also improve service integration across Australia. The key dimensions of this finding are discussed next in more detail. Case management is key for achieving Service User outcomes for complex cases—89% of survey respondents either agreed or strongly agreed this was the case. Interviewees most frequently said they would provide more case management if they could change their service model. Case management allows for more time spent with the Service User, follow up with referral partners, and a higher level of expertise in service delivery to support complex cases. Of course, it is a costly model and not currently funded for all Service Users through ER. Where case management is not available as part of ER, it might be available through a related service that is part of a network of support. Where possible, ER Providers should facilitate access to case management for Service Users who would benefit. At a system level, ER models with a greater component of case management could be implemented as test cases. Referral systems are also key for achieving Service User outcomes, which is reflected in the ER Program Logic presented on page 31. The survey and interview data show that referrals within an integrated service (internal) or in a service hub (co-located) are most effective. Where this is not possible, warm referrals within a trusted network of support are more effective than cold referrals leading to higher take-up and beneficial Service User outcomes. However, cold referrals are most common, pointing to a weakness in ER referral systems. This is because ER Providers do not operate or co-locate with interrelated services in many cases, nor do they have the case management capacity to provide warm referrals in many other cases. For mental illness support, which interviewees identified as one of the most difficult issues to deal with, ER Providers offer an integrated service only 23% of the time, warm referrals 34% of the time, and cold referrals 43% of the time. A focus on referral systems at the individual ER Provider level, and system level through a joined-up approach, might lead to better outcomes for Service Users. The program logic and theory of change for ER have been documented with input from the research findings and included in Section 4.3 on page 31. These show that ER helps people facing a financial crisis to meet their immediate needs, avoid further harm, and access a path to recovery. The research demonstrates that ER is fundamental to supporting vulnerable people in Australia and should therefore continue to be funded by government.
