Energy Usage of Personal Rapid Transit Systems : Simulation of the SkyCab ConceptVogel, Alexander January 2015 (has links)
Den globala situationen för person- och godstransporter visar att energianvändningen inom transportsektorn stadigt ökar och prognoser tyder på att den kommer att fördubblas till 2050. Den största ökningen förväntas ske i Asien där, Kina kommer att stå för över 12 % av den globala energianvändningen år 2050. Inom EU, Europeiska Unionen, stod personbilarna 2012 för över 81 % av passagerartransporterna räknat i antal passagerarkilometrar. Nya energieffektiva och miljövänliga transportlösningar behöver utvecklas. En lösning med spårtaxi kombinerar fördelarna med konventionella vägtransportsystem (flexibilitet, tillgänglighet och attraktivitet) och spårtransportsystem (säkerhet, kapacitet och miljövänlighet). I detta examensarbete undersöks energianvändningen för spårtaxi. Detta sker i form av en fallstudie. Spårtaxi är en automatiserad transporttjänst för direktresor utan väntetider (likt taxiservice) i ett nätverk med banor som kompletterar masstransportsystem. Fokus i studien ligger på att utvärdera fordonens energianvändning i drift. Målet är att identifiera relevanta parametrar som avgör energianvändningen samt deras bidrag till denna. Frågan om effektiv energianvändning besvaras med hjälp av en simuleringsmodell. Denna baseras på konceptet SkyCab och en bedömning av fordonets parametrar. En beräkning är utförd som utgör en referens för att sedan jämföras med 16 variationer av nyckelparametrar. Relationen till växhusgaser undersöks och utsläppen beräknas för olika elektricitetsblandningar. Ett andragradspolynom är framtaget för att beskriva fordonets gångmotstånd som inkluderar uppskattningar av vagnens rullmotstånd för små, pneumatiska däck på en raksträcka samt i doserade kurvor. Hjälpkraftens energianvändning uppskattas säsom motsvarande en liten elektrisk bil och är starkt beroende av passagerarnas komfortbehov och yttre (väder)förhållanden. Ett resultat är att rullmotståndet står för cirka 44 % av energianvändningen och hjälpkraften för 33 %. Båda är potentiella mål för effektivitetsförbättringar. Ändringar av accelerationsnivåer har liten betydelse för energianvändningen då det är en mindre del av energin som regenereras. En ökning av topphastigheten är ett effektivt sätt att minska restiden med förhållanderis liten ökning av energianvändningen. Förslag lämnas i studien hur man kan minska energianvändningen genom att förbättra fordonets och banans nyckelegenskaper. / he global situation of personal and freight transport shows that the energy demand for transportation steadily increases, and prognoses indicate that the energy usage will double until 2050. The largest growth rates are expected in Asia, and China in particular will account for over 12 % of global transport energy usage in 2050. Over 81 % of passenger transport in passenger kilometre was produced by passenger cars in 2012 in the European Union, and new energy eÿcient and environmental friendly solutions have to be developed.PRT (Personal Rapid Transit) systems combine the benefits of traditional road systems (flexibility, accessibility, attractiveness) and rail systems (safety, capacity, environmental friendliness). This MSc thesis investigates a concept by SkyCab AB as a case study, which o˙ers an automated, non-stop and on-demand transportation service in a dedicated network and is supposed to fill a gap between personal cars and public transport. The focus is put on the energy usage of the vehicles in the operational phase.The objective is to identify the relevant parameters that determine the energy usage and their contributions. This request is addressed by setting up a simulation model, based on the SkyCab concept and estimations of vehicle parameters. A reference calculation and 16 variations of key parameters are conducted. The relation to greenhouse gas emissions is investigated and emissions are calculated for di˙erent electricity mixes.A second-order polynomial of running resistance for the vehicle is determined, includ-ing estimations of rolling resistance of small pneumatic tyres on straight track and in superelevated curves. The auxiliary power is estimated for the SkyCab vehicle on basis of a small electric passenger car.For the reference case the energy for rolling resistance is approx. 44 % of the energy usage, and auxiliary energy contributes by 33 %. Both o˙er potential for eÿciency im-provement. The auxiliary power is strongly dependent on the passengers’ comfort needs and the ambient conditions. Changes of acceleration rates have low impact on the energy usage, since a smaller proportion of energy is regenerated. An increase in top speed is a suÿcient measure to reduce trip time with comparably low increase in energy usage. Finally, suggestions are proposed to reduce the energy usage by improving key properties of the vehicle and guideway. / Der weltweite Energiebedarf des Personen- und Gütertransports zeigt einen kontinuier-lichen Anstieg, und der Ausblick bis 2050 zeigt eine Verdopplung des gesamten Ener-giebedarfs. Die größten Zuwachsraten werden in Asien erwartet, und insbesondere China allein wird in 2050 über 12 % des weltweiten Energiebedarfs verzeichnen. Über 81 % aller Personenkilometer in der Europäischen Union in 2012 wurden mit dem persönlichen Auto-mobil durchgeführt, und ein Bedarf für energieeÿziente und umweltfreundliche Transport-möglichkeiten wird deutlich.PRT (Personal Rapid Transit) Systeme vereinen die Vorzüge von traditionellen straßenge-bundenen Transportsystemen (Flexibilität, Zugänglichkeit, Attraktivität) und Schien-ensystemen (Sicherheit, Kapazität, Umweltfreundlichkeit). Diese MSc Thesis untersucht das Transportkonzept von SkyCab AB als Fallstudie. Es bietet einen automatisierten, un-unterbrochenen und bedarfsgesteuerten Transportdienst auf einem exklusiven Netzwerk und soll so die Lücke zwischen dem persönlichen Automobil und ö˙entlichen Transport-mitteln schließen. Der Fokus wird dabei auf den Energieverbrauch des Fahrzeugs in der operativen Phase gelegt.Die Zielsetzung besteht in der Identifizierung und Quantifizierung der relevanten Para-meter, die den Energieverbrauch bestimmen. Zu diesem Zweck wird ein Simulationsmodell konfiguriert welches auf dem Konzept von SkyCab basiert und zusätzlich Abschätzungen von Fahrzeugparametern enthält. Eine Referenzberechnung und 16 Parametervariationen werden durchgeführt. Der Bezug zur Emission von Treibhausgasen wird für verschiedene Energiemixe hergestellt.Das Polynom zweiter Ordnung für den Fahrwiderstand wird aufgestellt, wobei Abschätzun-gen bezüglich des Rollwiderstands kleiner pneumatischer Reifen auf gerader Strecke und in überhöhten Kurven berücksichtigt werden. Die Zusatzleistung für das Konzeptfahrzeug wird auf Basis eines kleinen rein elektrischen Fahrzeugs abgeschätzt.Der Energieverbrauch in der Referenzsimulation für den Rollwiderstand beträgt ca. 44 % des Gesamtenergieverbrauchs, und die Zusatzenergie beläuft sich auf ca. 33 %. Beide Anteile bieten Potential zur Optimierung, und die Zusatzenergie ist stark abhängig von den Komfortbedürfnissen der Passagiere und den Umgebungsbedingungen. Variationen der Beschleunigungs- und Bremsraten haben einen geringen Einfluss auf den Energiever-brauch, da gleichzeitig ein kleinerer Anteil regeneriert wird. Eine Zunahme der Höchst-geschwindigkeit wirkt sich durch mehr regenerierte Energie vergleichsweise gering auf den bezogenen Energieverbrauch aus, reduziert jedoch die Fahrzeit merklich. Abschließend werden Potentiale von Schlüsselparametern zur Reduktion des Energieverbrauchs des Fahrzeugs und der Fahrbahn aufgedeckt.

"Stress som försvinner" : En kvalitativ studie om karriärväxling med omställningsstudiestöd / ”Stress that disappears” : A qualitative study on career change with transition study supportHalkjaer, Jenny January 2023 (has links)
Syftet med studien är att bidra med en fördjupad förståelse för orsaker till karriärväxling hos individer som sökt omställningsstudiestödet. Frågeställningarna som använts för att undersöka studiens syfte är följande: vilka faktorer har initierat önskan att vilja karriärväxla och hur ser respondenterna på sina möjligheter att karriärväxla med omställningsstudiestödet. En kvalitativ studie med ett hermeneutiskt perspektiv har genomförts, där en abduktiv ansats har använts för att dra slutsatser om studiens resultat. Ett kriterieurval har skett och sex respondenter valdes ut till studien. Empirin har samlats in med hjälp av semistrukturerade intervjuer och därefter har en innehållsanalys genomförts. Teorier och begrepp som använts vid analys av resultat är karriärvalsteorin Careership med begreppen handlingshorisont, habitus och brytpunkter. Som ett komplement används även metakarriärteorin System Theory of Framework med begreppen influenser, processinfluenser och system. Studiens resultat visar att omställningsstudiestödet inte påverkar respondenternas val i någon större utsträckning när det kommer till att karriärväxla. Faktorer som initierat en önskan att karriärväxla hos respondenterna i studien berodde på flera olika orsaker. Det som framkom i resultatet var: arbetsmiljö, hälsoproblematik, utvecklingsbehov och viljan att testa nytt. Avslutningsvis, omställningsstudiestödet är en möjlighet till karriärväxling men det är inte en enskild faktor till beslutet att karriärväxla utifrån studiens resultat.

Parameter Estimation and Simulation of Driving Datasets / Parameteruppskattning och simulering av kördatauppsättningarQu, Bojian January 2023 (has links)
The development of autonomous driving in recent years has been in full swing and one of the aspects that Autonomous Vehicles (AVs) should always focus on is safety. Although the corresponding technology has gradually matured, and AVs have performed well in a large number of tests, people are still uncertain whether AVs can cope with all possible situations. This world is complex and ever-changing, experiencing countless disturbances every moment, and according to The Butterfly Effect, even the most insignificant small disturbance may set off a huge storm in the near future. If AVs really enter people’s daily lives, they will inevitably encounter many unexpected situations that have never been experienced before. Thus how to ensure that AVs can handle these well has become the most important issue at the moment. It is necessary to give the Automated Driving System (ADS) sufficient challenges during training and testing for acceptable safety and stability. However, dangerous and extreme driving scenarios in the real world are very rare, and it is also very expensive for such a test to be carried out in reality. Therefore, artificially creating a series of critical driving scenarios then training and testing the ADS in a simulation environment has become the current mainstream solution. This thesis project builds a complete framework for the automatic generation, simulation, and analysis of safety-critical driving scenarios. First, the specified scenarios and features are sequentially extracted from the naturalistic driving dataset through pre-defined rules; then a Density Estimation Model is adopted to learn the features, trying to find the distribution of the specified scenarios; after the distribution is obtained, synthetic driving scenarios can be obtained by sampling. Finally, visualize these synthetic scenarios via simulation for safety assessment and data analysis. / Utvecklingen av självkörande fordon har varit i full gång de senaste åre och en av aspekterna som självkörande alltid bör fokusera på är säkerheten. Även om motsvarande teknik gradvis har mognat, och självkörande har presterat bra i ett stort antal tester, är människor fortfarande osäkra på om självkörande klarar av alla möjliga situationer. Den här världen är komplex och ständigt föränderlig, upplever otaliga störningar varje ögonblick, och enligt The Butterfly Effect kan även den mest obetydliga lilla störningen sätta igång en enorm storm inom en snar framtid. Om självkörande verkligen kommer in i människors dagliga liv kommer de oundvikligen att möta många oväntade situationer som aldrig har upplevts tidigare. Så hur man säkerställer att självkörande kan hantera dessa väl har blivit den viktigaste frågan för tillfället. Det är nödvändigt att ge självkörande tillräckliga utmaningar underträning och testning för acceptabel säkerhet och stabilitet. Men farliga och extrema körscenarier i den verkliga världen är mycket sällsynta, och det är också mycket dyrt att genomföra ett sådant test i verkligheten. Att på konstgjord väg skapa en serie kritiska körscenarier och sedan träna och testa det automatiserade körsystemet i en simuleringsmiljö har därför blivit den nuvarande vanliga lösningen. Detta examensarbete bygger ett komplett ramverk för automatisk generering, simulering och analys av säkerhetskritiska körscenarier. Först extraheras de specificerade scenarierna och funktionerna sekventiellt från den naturalistiska kördatauppsättningen genom fördefinierade regler; sedan antas en densitetsuppskattningsmodell för att lära sig funktionerna och försöka hitta fördelningen av de specificerade scenarierna; efter att fördelningen erhållits kan syntetiska körscenarier erhållas genom provtagning. Slutligen, visualisera dessa syntetiska scenarier via simulering för säkerhetsbedömning och dataanalys.

GTO to GEO Optimal Trajectory Profiles and Electric Propulsion System Configuration / Optimala banprofiler från GTO till GEO och konfiguration av elektriska framdrivningssystemAlliri, Maria Pilar January 2024 (has links)
Quick and reliable computational methods for optimized orbital transfers are crucial for projects at preliminary stages. They enable an initial, realistic sizing of the propulsion subsystem, one of the major components of satellite design. This thesis work, conducted at ReOrbit Oy, presents a minimum-time optimal trajectory for the orbit raising of a micro-satellite from GTO to GEO, assuming continuous firing by electric propulsion. The Delta-v requirements resulting from this simulation lead to the selection of an appropriate electric propulsion system, elaborating on the design of its configuration in terms of fuel and thrust requirements. This is done by taking into account, other than the major contribution given by the orbit raising, additions due to in-orbit maneuvers performed twice a day over a 10-year lifetime, like station-keeping corrections and reaction wheels desaturation. The optimization method is a direct-indirect hybrid for low-thrust orbital maneuvers, employing Pontryagin’s Minimum Principle for the transcription into a nonlinear programming problem. The initial guess required to start the optimizer is obtained with Lyapunov control theory. An orbital averaging technique is implemented, enabling fast computation of multiple trajectories during the optimization. Disturbances from the J2 zonal harmonic, solar radiation pressure, third-body effects of the Sun and Moon, and atmospheric drag up to 1500 km of altitude are included in the dynamic model. Eclipse conditions are assessed with a cylindrical shadow model, as the solar electric propulsion experiences a zero thrust period when in Earth’s shadow. The electric propulsion system configuration is determined with trade-off studies and comparisons between different suppliers. The chosen outline includes 4 Xenon thrusters, with complementary power processing units and propellant management systems, resulting in a total transfer time of less than 4 months. The same propulsion system is employed both for the transfer trajectory and the in-orbit maneuvers, by changing the thruster’s configuration once in GEO. / Snabba och pålitliga beräkningsmetoder för optimerade växlingar mellan omloppsbanor är avgörande för projekt i preliminära skeden. De möjliggör en initial, realistisk dimensionering av framdrivningssystemet, ett av huvudkomponenterna i satellitdesign. Detta examensarbete, utfört vid ReOrbit Oy, presenterar en tidsoptimerad bana för en mikrosatellits banhöjning från GTO till GEO, förutsatt kontinuerlig avfyring med elektrisk framdrivning. Simuleringens resulterande Delta-v-krav leder till valet av ett lämpligt elektriskt framdrivningssystem, med utarbetande av dess konfiguration vad gäller bränsle- och drivkraftskrav. Detta uppnås genom att ta hänsyn till (förutom bidraget från växlingen av omloppsbanan) tillägg från manövrar i omloppsbana som utförs två gånger om dagen under en 10-årig livstid, som t.ex. korrigeringar för stationshållning och avmättning av svänghjul. Optimeringsmetoden är en direkt-indirekt hybrid för manövrar i omloppsbanor med låg drivkraft, som använder Pontryagins minimiprincip för omskrivning till ett icke-linjärt programmeringsproblem. Den första gissningen som krävs för att starta optimeraren erhålls med Lyapunovs reglerteori. En teknik for omloppsutjämning implementeras, vilket möjliggör snabb beräkning av flera banor under optimeringen. Störningar från zonövertonen J2, solstrålningstryck, tredjekroppseffekter från solen och månen och luftmotstånd upp till 1500 km höjd ingår i den dynamiska modellen. Förmörkelseförhållanden uppskattas med en cylindrisk skuggmodell, då den elektriska solframdrivningen undergår ett skede utan drivkraft inom jordens skugga. Det elektriska framdrivningssystemets konfiguration bestäms med avvägningsundersökningar och jämförelser mellan olika leverantörer. Förslaget på utformning inkluderar 4 Xenon raketmotorer, med kompletterande kraftbearbetningsenheter och drivmedelshanteringssystem, vilket resulterar i en total överföringstid på mindre än 4 månader. Samma framdrivningssystem används både för överföringsbanan och manövrarna inom omloppsbanorna, genom att ändra motorns konfiguration när satelliten är i GEO.

A transdisciplinary approach to dealing with child offenders with psychiatric disordersGeoffrey, Leandre Christina 12 1900 (has links)
This study aimed to develop a framework for improved legislation, methods of practice and services used to meet the best interest of child offenders with psychiatric disorders within the South African child justice system. This aim was achieved via a qualitative study, which evaluated child justice and mental health legislation, methods of practice, role-players, and services in South Africa, and compared same to those in Namibia, Botswana, and Nigeria; to establish if the best interest of child offenders with psychiatric disorders are currently met from a South African perspective.
Data collection occurred in two phases: a document analysis of legislation, policies, and procedures in the selected comparative jurisdictions; followed by semi-structured interviews with child justice and mental health experts. During phase one the researcher analysed child justice and mental health legislation, human rights protections, and policy related to child justice in Nigeria, Botswana, Namibia, and South Africa. In addition, she interrogated literature relating to child justice and mental health, in comparative jurisdictions. This phase formed the foundation for the semi-structured interview schedule. Purposive and theoretical sampling was used to conduct 24 semi-structured interviews. Data was analysed and interpreted using pure qualitative document and thematic analysis.
The overarching findings indicate that the best interest of child offenders with psychiatric disorders, in the South African child justice system, are unprotected. This vulnerable group is not dealt with from an individualised, case-specific, multi-disciplinary perspective; informed by legislation, practice-policy, and a service-orientated approach. Further, certain domestic legislation and methods of practice are inadequate in holistically assessing a child who comes into conflict with the law in the jurisdictions of comparison.
Further findings identified that biological, psychological, environmental, cultural, and social factors influence the development of psychiatric disorders in children, which may bring them into conflict with the law. This study further confirmed that Attention Deficit Hyperactivity Disorder, Intellectual Development Disorder, Learning Disorder, Oppositional Defiant Disorder, and Conduct Disorder are prevalent in children who
iv
come into conflict with the law. Further, substance abuse disorder, depression and attachment disorder were identified as predominant factors affecting children who come into conflict with the law. The influence of these factors, in conjunction with biological, psychological, environmental, cultural, and social factors, were found to predispose children to psychiatric disorders linked to criminal behaviour.
Thus, to meet the best interest standard; children in conflict with the law must be dealt with using a multi-factorial approach which considers biological, environmental, social, cultural, and psychological factors. In this way, the behaviour of child offenders with psychiatric disorders will be addressed holistically in a manner that considers all factors influencing behaviour. The empirical data supported the recommendations used to develop a trans-disciplinary framework for child offenders with psychiatric disorders. / Olu phononongo lwesi sifundo lujolise ekuphuhliseni isakhelo somthetho ophuculiweyo, iindlela zokusebenza kunye neenkonzo ukwenzela ukunikezela ezona zilungileyo iimfuno zabantwana abangabaphuli-mthetho benengulo yesifo sengqondo kwinkqubo yobulungisa yabantwana eMzantsi Afrika.

Exploring aftercare support for child trafficking victimsRamokolo, Kholofelo Portia 15 August 2019 (has links)
Child trafficking is a crime committed against humanity; it is punishable by the law and can be prevented by the law. According to the International Labour Organization (ILO), the United Nations International Emergency Fund (UNIICEF) and the United Nations Global Initiative to Fight Human Trafficking (UN.GIFT) (2009:01), 1,2 million children are trafficked, domestically and across borders worldwide, for labour and sexual exploitation, drug trade, organ removal and illegal child adoption. The trauma of this can be so inordinate, leaving victims broken and hopeless (Frederick 2005:8-12). Although numerous studies have been conducted on the subject of human/child trafficking, it was found that little research has been conducted on the aftercare of victims. As a result, this research focused mainly on exploring and assessing aftercare support provided to victims of human trafficking, specifically children. This qualitative research found that child trafficking has serious negative effects on the victims who suffer, among others, violation of children’s rights, physical pain and psychological and emotional trauma. A society cannot function optimally when such atrocities are committed against its most innocent members who are supposed to be its future. Accordingly, adequate aftercare support, which aims at enabling and empowering victims of child trafficking to regain control over every aspect of their lives, is crucial. The 30 participants who were interviewed for this study revealed that victim identification is the initial and the most vital step towards offering victims aftercare. The next step in the offering of aftercare of victims is the rescuing of victims followed by the immediate placing of victims in transitory places of safety where their basic needs are taken care of and they are provided with instant physical and specialised psychological support. Even though participants provided details of the type of programmes currently offered in South Africa, it was found that aftercare centres, in their current state, are not sufficiently resourced to offer the appropriate support to victims of child trafficking. It is for this reason that transitional housing with long term housing assistance and programmes tailor-made for victims of child trafficking be considered. It is evident from the literature and theory that the triple challenge of poverty, inequality and unemployment perpetuates the crime of child trafficking. Therefore, as a form of long-term preventative measure, it is suggested that stakeholders, such as the Department of Basic Education (DoE), Department of Social Development (DSD) and Department of Health (DoH), focus attention on ensuring that victims of child trafficking are not denied the right to go to school and that societal norms, which propagate inequality, are discouraged. The latter can be done by teaching boy children from a young age positive masculinity, such as respecting girl children and their bodies, helping with house chores or crying when in pain. Moreover, the DoE should consider revising its curriculum and focus on teaching learners to strive to become employers and not job seekers as they are currently taught. This may have a positive impact on the current high unemployment rate in South Africa and, in turn, inequality and poverty, which are all push factors for human and child trafficking. / Go gweba ka bana ke bosenyi bjo bo dirwago kgahlanong le batho; ke bosenyi bjo bo otlwago ke molao gomme bo ka thibelwa ke molao.

Mmino wa Bana: An African musicological study of Moletjie community musical practicesMokgetle, Morokolo 21 September 2018 (has links)
PhD (African Studies) / Department of African Studies / Mmino wa bana (Children’s songs) are subjected to many changes today; so much so that in time it could cease to exist in its original form or be replaced by genres promoted on televisions. This study focuses on the genre as practised in the Moletjie community. The study explores mmino wa bana by examining its musicological elements, educational validity, and the general social functions within the context of the Moletjie community. By providing insight into these aspects, we could be able to ascertain the transportability of musical elements and philosophies across many contexts. Twenty-one children’s songs were collected for the study. In addition, interviews were conducted with elders and members of the Moletjie royal family to capture the narrative views of the genre. Additional information was also captured in the form of diary notes. The study used an Afrocentric approach as its theoretical framework. The design was qualitative with semi structured interviews functioning as the mode of data collection. For analysis, music programs were used. The body of knowledge emanating from the study is packaged in such a way that it could be used by scholars in African musicology, policy planners, and others interested in the culture of the people of Moletjie community. The school will also find the study to be a useful resource in crafting textbooks for classroom purposes. / NRF

Widows and the abuse of husbands’ property: an analysis in the novels Ifa lenkululeko and Ifa ngukufa / Abafelokazi nokuhlukunyezwa kwempahla yababayeni babo: ukuhlaziywa kwamanoveli Ifa lenkululeko kanye ne-Ifa ngukufa / Bahlolohadi le tshebediso e mpe ya thepa ya banna: manollo dibukeng tsa dipale Ifa lenkululeko le Ifa ngukufaMcira, Malefu Renia 11 1900 (has links)
Bibliography: leaves105-117 / Summaries followed the Bibliography / The study investigates the abuse of husbands’ property by widows in the two selected isiZulu
novels Ifa ngukufa and Ifa lenkululeko, which is found to have a huge impact on children and
family members. The study presents the causes of the abuse of husbands’ property, the course
of action of abusing husbands’ property and the consequences thereof. The content analytical
approach has been used to analyse the two novels. The analysis reveals that some of the
causes of the abuse of husbands’ property by widows are the widows’ carelessness, weakness,
lack of respect, stress and laziness. In both literary texts, widows abuse their husbands’
property with their new lovers. As persons living in modern times, they do not respect the
African cultural practices. They refuse to wear mourning clothes for their late husbands, as
required by the African culture. Instead, they find new lovers within a few days of their
husbands’ death, and invite them to stay in their husbands’ houses. The study highlights how
easily some people, including widows, can be influenced by other peoples’ cultures. They do
not respect their parents, children and the in-laws; and do not pay attention to the wellbeing of
their children. When the money is depleted, the new lovers go back to their families. The
study further reveals that, after the departure of the new lovers, the widows realise that they
(new lovers) were not in love with them, but were after their properties. The presence of the
new lovers in the widows’ lives has a negative effect on family members. Consequently, the
relationship between the widows and the in-laws, parents and children suffers. The
investigation is concluded by presenting recommendations that will help widows to avoid
tricksters from robbing them of their property. The study is of great value to children who
become the victims of circumstance. / Ucwaningo luphenya ngokuhlukunyezwa kwempahla yabayeni ngabafelokazi kumanoveli

isiphelile, amashende abo amasha abuyela emindenini yabo. Ucwaningo luqhubeka
ngokuveza ukuthi, ngemuva kokuhamba kwamashende abo amasha, abafelokazi bayabona
ukuthi wona (amashende amasha) abengabathandi, kepha babelandela impahla yabo. Ukuba
khona kwamashende amasha ezimpilweni zabafelokazi kunomthelela omubi kumalungu

Conceptual Design of an Air-Launched Three-Staged Orbital Launch Vehicle / Konceptuell Design av en Luftlanserad TrestegsraketRasmussen, Måns January 2021 (has links)
The objective of this study was to design a launch vehicle capable of deploying a nanosatellite into a Sun-synchronous orbit at 500 km orbital altitude from the JAS 39E/F Gripen fighter aircraft. This was achieved by first performing theoretical calculations for the required nozzles and solid propellant grain configurations for the first two solid stages, followed by the necessary liquid propellant configuration for the third stage. Lastly, two methods were investigated in solving the trajectory ascent problem for the launch vehicle design. First, by stating the trajectory problem as an initial value problem while guessing a Sigmoidal steering law. Secondly, by stating the trajectory problem as a boundary value problem. The latter was solved by transcribing the trajectory problem into a nonlinear program where a parametric steering law was derived using a Sequential quadratic programming algorithm.Ultimately, resulting in a launch vehicle design with a gross lift-off mass of 1,289 kg, capable of launching an 8.4 kg payload into the targeted orbit, with suggested modifications to increase the possible payload mass to 12.9 kg. / Målet med den här studien var att designa en luftlanserad trestegsraket kapabel till att transportera en nanosatellit upp till en solsynkron omloppsbana på 500 km altitud från ett JAS 39E/F Gripen jaktflygplan. Det gjordes genom att först beräkna de nödvändiga dysorna och krutladdningsformerna för de två första stegen tillsammans med en flytande bränsledesign för det tredje steget. Två metoder undersöktes för bananalysen. Först genom att anta en Sigmoidal styrningsfunktion för pitchen, sedan genom att transkribera problemet till ett icke-linjärt program där en parametrisk styrlag togs fram genom att använda en Sequential quadratic programming algoritm. Slutligen presenterades en raketdesign med en total vikt på 1 289 kg, kapabel till att skjuta upp en nyttolast på 8,4 kg till den önskade omloppsbanan tillsammans med förslag som kan öka den möjliga nyttolasten till 12,9 kg.

Perceptions of parents/guardians about the effectiveness of future families programme in OlievenhoutboschEale Essosola, Kris 11 1900 (has links)
Abstract in English, Sepedi and Zulu / The people with the greatest stake in Orphan and Vulnerable Children (OVC) interventions are the children and their parents/guardians. Unfortunately, most OVC programmes are predesigned and implemented without considering beneficiaries’ perceptions when developing solutions (ALI 2007:15). The purpose of this study was to explore and describe the perceptions of orphans and vulnerable children’s parents/guardians about the effectiveness of Future Families’ children programme in Olievenhoutbosch. This study used a qualitative, explorative and descriptive design. Thirteen parents/guardians of children registered with the Future Families were interviewed on the effectiveness of the Future Families programme using a semi-structure interview guide. The study results suggested that parents/guardians were happy with Future Families’ services and believed the programme is effective in responding to their families’ needs / Abantu abathinteka kakhulu ekungeneleni kokuphathelene nezintandane kanye nabantwana abasengcupheni (ama-OVC) ngabantwana kanye nabazali noma abaqaphi. Ngeshwa, izinhlelo eziningi zama-OVC zenziwe futhi ziqala ukusetshenziswa ngaphandle kokucabangela imibono yalabo okumele bahlomule kwizisombululo zokuthuthukisa (ALI 2007: 15). Inhloso yalolu cwaningo kwakuwukuhlola nokuchaza imibono yabazali nabaqaphi bama-OVC mayelana nokusebenza kohlelo lwabantwana olunikezwa yiFuture Families e-Olievenhoutbosch.
Kwasetshenziswa uhlelo oluhlolayo noluchazayo kulolu cwaningo. Abazali abayishumi nesishiyagalolunye noma abaqaphi babantwana ababhalisiwe kwaFuture Families, okuyinhlangano engenzi nzuzo ehlinzeka izinsizakalo kuma-OVC nakubantu abaneHIV/AIDS noma abahlukumezekayo ngenxa yalokho, babuzwa imibuzo kusetshenziwa umhlahlandela wemibuzo ehlelekile kwezinye izindawo ukuze baveze imibono yabo maqondana nokusebenza ngempumelelo kohlelo lweFuture Families.
Imiphumela yalolu cwaningo iphakamise ukuthi abazali nabaqaphi bagculisekile ngemisebenzi ehlinzekwa yiFuture Families, futhi bakholwa ukuthi lolu hlelo lusebenza ngempumelelo ukubhekana nezidingo zemindeni yabo. / Batho ba ba nago le setseka se segolo go ditseno ka bogare tša Bana ba Ditšhiwana le bao ba lego Kotsing (OVC) ke bana le batswadi/bahlokomedi ba bona.
