International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / For faster acquisition in bursted environments for SMS (Short Messaging Service) and other lower-bit rate applications, non-coherent detection techniques are proposed. Non-Coherent detection demodulators are proposed because faster acquisition capability in bursted environments can result in a reduced amount of preamble bits in the messaging frame, i.e. less overhead, resulting in an effective increase in spectral efficiency. Reducing the preamble can also provide performance enhancement opportunities for Feher Quadrature Phase Shift Keying (FQPSK) [1] and for other systems. The preamble can also be varied to provide for better Bit Error Rate (BER) performance. The lower bit rate environment also gives the opportunity to employ simpler architectures in lieu of preamble modification. Several non-coherent detection alternatives are described.

Class of 2017 Abstract / Objectives: The first aim is to assess efficacy of aspirin versus enoxaparin in preventing a venous thromboembolism (VTE) after a total knee arthroplasty (TKA) or total hip arthroplasty (THA) within 30 days after discharge. The second aim is to assess the safety of aspirin versus enoxaparin in preventing major bleeding events after a TKA or THA within 30 days after discharge. Methods: This study was a retrospective cohort study with data obtained from an online Veterans Affairs (VA) hospital database. For analysis, the primary outcome was assessed with a Chi-Square test, and the secondary outcome was reported with descriptive statistics.Results: Results: Demographics for 374 patients (TKA, n = 275; THA, n = 99): 90% male, average age of 65, average body mass index (BMI) of 32, 26% smokers, 72% had a history of hypertension, and 60% had a history of dyslipidemia. VTE events 30 days post-operatively: enoxaparin (n = 2), enoxaparin/aspirin (n = 1), and aspirin (n = 2) (P-value = 0.78). Safety events (major bleeding events): enoxaparin (n = 42), enoxaparin/aspirin (n = 7), and aspirin (n = 4). Conclusions: There was no significant difference between the treatment groups for VTE rate 30 days post- operation. The enoxaparin treatment group had the greatest number of safety events compared to the other groups.

This thesis is an empirical review of neighborhoods in the Richmond Region based on factors of inclusion and quality of life. The research attempts to answer the question of whether or not healthy and inclusive neighborhoods exist in the Richmond Region, and if they do what factors they hold in common. Inclusion and quality of life are identified using census data, school assessment reports, HUD reports, and cause-of-death data applied at the neighborhood level (census tract). This data is used to identify neighborhoods within the Richmond Metropolitan Statistical Area (MSA) that have a high quality of life and include racial minorities and low-to-moderate income households at a rate that reflects the region as a whole. Finally, the census tracts that fit these criteria are analyzed to determine correlating factors. The analysis determined that inclusive census tracts with a high quality of life tend to be majority-black suburban neighborhoods located near the urban cores or Richmond and Petersburg. These neighborhoods had a mix of housing types, moderate homeownership rates, newer housing options, access to public schools, access to commercial goods and services, and households with moderate incomes. Policies that promote these types of environments will help create and sustain healthy and inclusive neighborhoods.

Denna studie handlar om en metod som används för att lokalisera inläckage av tillskottsvatten på spillvattennät. Grunden är de praktikperioder som författaren har haft hos VA-bolaget Helsinge Vatten AB och då det utförts flera försök till att utreda inläckage i spillvattenledningarna. Metoden går ut på att analysera koncentrationen av ammonium i flödet som hämtas från brunnarna ute på nätet. Analyserna sker med hjälp av en portabel spektrofotometer tillsammans med reagenskyvetter som analyserar koncentrationen på bara 15 minuter. Detta ger en indikation på hur utspätt spillvattnet är, om det är utspätt av tillskottsvatten så visar analysen ett lågt värde vilket tyder på inläckage av dagvatten, grundvatten eller dricksvatten. Denna metod är framtagen av Norrköping Vatten och Avfall som har lyckats bra med att lokalisera inläckage med metoden. Norrköping Vatten och Avfall är en stor källa till denna studie med sin rapport ”Minskning av in- och utläckage genom aktiv läcksökning”(Uusijärvi, 2013).  I rapporten redovisas de ammoniumanalyser som har gjorts med tillhörande diagram för att tydliggöra resultaten. Eftersom spillvattennät ofta hör samman med pumpstationer och reningsverk som påverkar elförbrukning har statistik tagits fram för den pumpstation som analysområdet hör samman med. Elförbrukning har jämförts med nederbördsmätning för att se om ledningsnätet är påverkat av nederbörd, eftersom pumpstationen får arbeta mer om det är tillskottsvatten i ledningarna.  För att få fram en uppskattad mängd inläckage så har en beräkning gjorts med hjälp av en mall som Norrköping vatten och avfall har tagit fram. Där används analysvärden som tyder på inläckage tillsammans med antal abonnenter, ledningssträcka och storförbrukares avlopp. Tillsammans blir det ett värde på uppskattat inläckage i liter per dygn och meter ledning(L/D/M).  I rapporten finns det tre områden som ingår i byn Rengsjö som är utredda med ammoniummetoden. I ett testområde blev resultatet inte som önskat men lärorikt för personalen. Ett område gav resultat som visar på god kvalitet av nätet med en jämförelse av torr- och regnväder. Samt ett område där ett troligt inläckage upptäckts som kommer utredas vidare under sommaren. Detta fynd kan ge stora mängder tillskottsvatten, vilket uppfyller delar av de mål som formulerats i rapporten, dvs. att hitta inläckage för att planera vidare utredning. Tillsammans med resultaten för varje område finns en omfattande diskussion där alla aspekter som påverkar de uppmätta analysvärdena tas upp.  Som slutsats konstateras ammoniummetoden som mycket framgångsrik i syfte för Helsinge Vatten att systematiskt kunna kartlägga och utreda sina spillvattennät. Det är en kostnadseffektiv och inte så resurskrävande metod som företaget själv kan använda på en lagom nivå. / This study aims to locate the intrusion of excess water in the sewage networks, analyzing the concentration of ammonium in the flow that is obtained from the wells in the network. The foundation for the work is the author’s previous attempts to investigate stormwater at the VA-company Helsinge Vatten AB. The analysis is carried out by using a portable spectrophotometer with such reagents that can measure ammonium concentration in just 15 minutes. This gives an indication of how diluted effluent is. If  it is diluted by excess water the analysis shows a low value which is indicating intrusion of possibly surface water, groundwater or drinking water. This method is developed by Norrköping vatten och avfall, who have been a major reference of this report, with their study “Minskning av in- och utläckage genom aktiv läcksökning”(Uusijärvi, 2013).  Results from the ammonium analyses have been presented with associated charts. Because the sewage networks often are associated with pumping stations and wastewater treatment plants, which effect the electricity consumption, the electricity consumption has been documented for the pump stations in the area of study. The electricity consumption increases when the pumps are working. A analysis has been made by comparing the electricity consumption and the precipitation to see if the sewage network is influenced by precipitation.  In order to obtain an estimated amount of excess water intrusion, a calculation have been made by using a template produced by Norrköping Vatten och Avfall. In the calculation, values indicating water intrusion along with the number of subscribers, management and those who discharge most wastewater have been used. Together it gives a result of estimated intrusion in liters per day and meter network (L/D/M).  In the report, three areas located in the village Rengsjö have been investigated by using this method. The first area where the outcome was not as desired, but very instructive for the staff. The second area gave results that show the good quality of the net with a comparison of dry and wet weather. And also an area where a likely intrusion is detected and will be investigated further during the summer. This finding can indicate large amounts of stormwater. Those findings compiles with parts of the objectives formulated in the report, to find the intrusion and to plan for further investigation. Together with the results for each area, include an extensive discussion in which all aspects that influence the measured analyses have been taken up.  The report shows that the ammonium method  has been proved to be successful in identifying excess water intrusion in Helsinge Vatten’s sewage networks. This method does not rely on many resources, and therefore it is suitable for companies that wish investigate excess water instruction in a cost-effective way.

Thesis (Ph.D. (History)) -- University of Limpopo, 2018 / The purpose of this study was to investigate the genealogy and migration of the va ka Valoyi people of Limpopo Province, South Africa. Qualitative, narrative research was used to study the oral history of the va ka Valoyi to determine the origin, migration routes and the genealogy of the 20 (twenty) communities of the va ka Valoyi in Limpopo. Data collection was done using semi-structured questionnaires. An initial list of 20 (twenty) respondents was drawn and through Snowball Sampling, the list was increased as per referrals made by the 20 (twenty) respondents during their individual interviews. At the end of the research, 67 (sixty-seven) respondents had been interviewed and secondary sources also consulted. The study has reconstructed the history of the va ka Valoyi, which had not been written before and managed to fill some gaps in the history of their associate groups that historians had not been able to fill in the past. The findings revealed that all the 20 (twenty) communities of the va ka Valoyi in Limpopo are related and identified the various relationships among them. It also revealed how the va ka Valoyi are related to ancient dynasties of the Munhumutapa, Changamire and Torwa and how they reached the Limpopo Province. KEY CONCEPTS Genealogy; Migration; va ka Valoyi; Arrival in Limpopo Province; Oral history.

RELATIONAL AESTHETICS: CREATIVITY IN THE INTER-HUMAN SPHERE By Carl Patow, MD, MPH, MBA A thesis submitted in partial fulfillment of the requirements for the degree of Master of Fine Art at Virginia Commonwealth University, 2019. Major Director: Pamela Taylor Turner, Associate Professor, Kinetic Imaging, VCU Arts Relational Art was first described as an art movement in Nicolas Bourriaud’s catalogue for the exhibition Traffic in 1995, and in an eponymous book in 1998. He observed that contemporary artists were shifting the focus of their work away from creating objects of spectacle to interaction with viewers through dialogue. Examination of a sample of representative artists’ work demonstrates a wide variety of applications that variously include objects. Inclusion of objects in relational artwork raises important theoretic considerations about the definition of the genre and its application to specific artworks. In the thesis artwork, WORKS WHEN, Carl Patow engages individuals in Richmond, Virginia, in conversations, documenting the location of their neighborhood and recording observations they make about their neighborhoods on polychrome tiles. The collected tiles are formed into “communities” on a floor map of the city. The work includes both conversation and objects in its creation, realization and exhibition. In doing so, WORKS WHEN is both an example of Relational Aesthetics and an expansion of its scope as a genre.

L'hypertension artérielle pulmonaire (HTAP) est définie par une pression artérielle moyenne >25 mmHg associée à une pression capillaire ≤ 15 mmHg. L'augmentation des résistances artérielles pulmonaires dans l'HTAP est associée à des phénomènes de vasoconstriction, de remodelage pariétal et de thrombose au niveau des artères pulmonaires de petit calibre. Plusieurs données expérimentales montrent que l'hypoxie est susceptible d'induire ces mêmes changements au niveau du lit artériel pulmonaire. De plus, d'après les petites cohortes étudiées dans la littérature, une hypoxémie nocturne (HN) serait fréquente dans l'HTAP pouvant se rencontrer chez presque 77% des malades. Les mécanismes de cette HN sont mal élucidés, en rapport avec une respiration périodique de type Cheyne Stokes (CS) pour certains auteurs, ou avec des apnées-hypopnées obstructives (AHO) du sommeil pour d'autres.Nous avons voulu ainsi explorer le sommeil des malades porteurs d'HTAP à la recherche de ces anomalies du sommeil et dans le but de déterminer leur prévalence et leurs mécanismes physiopathologiques. Quarante six malades hospitalisés dans le service de pneumologie de l'Hôpital Antoine Béclère, centre de référence national pour l'HTAP, ont bénéficié d'une nuit de polysomnographie (CIDELEC) avec une mesure de la capnographie transcutanée (TOSCA). Il s'agissait d'une population homogène comprenant 29 malades porteurs d'une HTAP idiopathique (HTAPI) et de 17 malades porteurs d'un coeur pulmonaire chronique postembolique (CPCPE), n'ayant pas d'anomalies fonctionnelles respiratoires sévères (VEMS etCPT ≥ 60 % de la théorique), ni d'obésité sévère (IMC < 35 Kg/m²), et stables depuis au moins 3mois, sous traitement spécifique optimal pour l'HTAP. Ces malades étaient pour la plupart en classe fonctionnelle II de la NYHA, parcouraient > 400m au test de marche de 6 minutes, etavaient un index cardiaque moyen mesuré sur le cathétérisme cardiaque droit dans les normes(3,2 ± 0,6 L/min/m²).La majorité (38/46 soit 82,6%) avaient une HN définie par un temps de sommeil passé avec uneSpO2 < 90%, > 60min et/ou un index de désaturation ≥ 20/h. Ces patients passaient 48.9 ± 35.9%de leur temps de sommeil avec une SpO2 < 90%. Le mécanisme le plus fréquemment rencontré(76% des malades désaturateurs) correspond à une hétérogénéité ventilation/perfusion (VA/Q)isolée ou associée à des AHO du sommeil. La prévalence des apnées-hypopnées (AH) était très élevée avec un index d'apnées-hypopnées (IAH) ≥ 5/h chez 89% des malades et un IAH moyende 24.9 ± 22.1/ h. La majorité de ces évènements était d'origine obstructive, seulement 4malades présentaient des AH de mécanisme central dont 3 avaient une respiration périodique de type CS. Un seul cas d'hypoventilation alvéolaire nocturne associé à un IAH obstructif modéré a été identifié, avec une désaturation nocturne prolongée concomitante d'une majoration significative de la capnie transcutanée de plus que 30 mmHg. Aucun facteur clinique ni hémodynamique n'a pu être identifié comme prédictif de la survenue de l'HN malgré certaines corrélations notées entre les paramètres de désaturation nocturne et la PaO2 diurne d'une part, et l'obstruction des petites voies aériennes d'autre part.Nous avons pu conclure que l'HN est fréquente dans l'HTAPI et dans le CPCPE, en rapport avec un déséquilibre VA/Q et/ou des AHO du sommeil. Reste à préciser dans des études ultérieures si la correction de cette HN aura des effets bénéfiques pour les patients en termes d'amélioration fonctionnelle, hémodynamique ou de réponse au traitement.
