In this thesis, we consider two types of positional games; Waiter-Client and Client-Waiter games. Each round in a biased (a:b) game begins with Waiter offering a+b free elements of the board to Client. Client claims a elements among these and the remaining b elements are claimed by Waiter. Waiter wins in a Waiter-Client game if he can force Client to fully claim a winning set, otherwise Client wins. In a Client-Waiter game, Client wins if he can claim a winning set himself, else Waiter wins. We estimate the threshold bias of four different (1:q) Waiter-Client and Client-Waiter games. This is the unique value of Waiter's bias q at which the player with a winning strategy changes. We find its asymptotic value for both versions of the complete-minor and non-planarity games and give bounds for both versions of the non-r-colourability and k-SAT games. Our results show that these games exhibit a heuristic called the probabilistic intuition. We also find sharp probability thresholds for the appearance of a graph in the random graph G(n,p) on which Waiter and Client win the (1:q) Waiter-Client and Client-Waiter Hamiltonicity games respectively.

The advent of robotics and automation leaves few industries untouched. Today, robots assist in everything between production lines at automotive manufacturing plants to home cleaning. One area that remains relatively untouched by robotics however, is the restaurant industry. The purpose of this bachelor’s thesis was to develop a prototype designed to assist with one of the tasks a restaurant waiter faces - food delivery. In order to accomplish this the robot must be able to drive and navigate in a restaurant environment and deliver food, all the while communicating with both restaurant staff and guests. The project resulted in a differentially steered robot that navigates using infrared, radio-frequency identification and ultrasonic modules. An elevator mechanism was devised to present the food to the guests. The user interface consists of a screen and a keypad. The prototype was tested successfully on an oval track measuring 3 by 1 meters. The tests showed that such a robot could likely be implemented in most restaurant settings.Tillkomsten av robotik och automatisering lämnar få industrier orörda. Idag assisterar robotar i allt från produktionslinjer på bilfabriker till hemstädning. Ett område som fortfarande är relativt orört av robotik är dock restaurangbranschen. Således var syftet med detta kandidatexamenarbete att utveckla en prototyp avsedd för att hjälpa till med en av de uppgifter som en restaurangservitör har - leverans av mat. För att uppnå detta måste roboten kunna köra och navigera i en restaurangmiljö och leverera mat, samtidigt som den kommunicerar med både restaurangpersonal och gäster. Projektet resulterade i en differentialstyrd robot som navigerar med hjälp av infraröd-, radiofrekvensidentifierings och ultraljudsmoduler. En hissmekanism konstruerades för att presentera maten för gästerna. Användargränssnittet bestod av en skärm och en knappsats. Prototypen testades framgångsrikt på en oval bana som mäter 3 gånger 1 meter. Testerna visade att en sådan robot troligtvis skulle kunna implementeras i de flesta restaurangmiljöerna.

Repatriation is an increasingly significant issue in the museum world. It is concerned with the return of cultural artefacts that have been previously traded or sold into foreign countries or institutions, either at the behest of the indigenous people or the initiative of the institution holding them. This dissertation explores the role of repatriation in modern New Zealand museums and its role in furthering the often contentious relationship between Maori and museum staff. It has a specific focus on the excavation and repatriation of human remains at Wairau Bar in Marlborough. It critiques an unpublished history of the Bar written by independent historian David Armstrong, which was commissioned by Rangitane in 2009. My overall argument disputes Armstrong's portrayal of Roger Duff, ethnologist at the Canterbury Museum, as the leader of a surreptitious excavation who was consistently underhand and secretive in his dealings with Rangitane. I counter Armstrong's claims to demonstrate that Duff valued an open and transparent relationship with Rangitane and respected their cultural attitudes to ancestral remains. I conclude that these remain core values in both modern repatriation policies and museum relations with Maori. My contextual discussion draws largely on secondary scholarship and journal articles while my conclusions about Wairau Bar are largely based on primary archives and Armstrong's report.

This project focuses on balancing a drinking glass, to be able to transport it without the contents being spilled. It is designed with the aim of replacing a waiter in a restaurant or bar environment, but the technology itself could well be applied on mobile cup holders in cars or boats for instance. The core of the project is to study how and if it is possible to create a platform capable of balancing a drinking glass when exposed to different acceleration forces. This report describes one way of constructing this cup holder, with explanations of how the hardware has been designed and put together as well as how the software was written to make the components work together. The objective was to tilt the platform so that the acceleration resultant always was aligned with the z-axis of the sensor. The balancing part was divided in two separate systems, each controlling one rotation around two perpendicular axes. The rotation was controlled by two DCmotors, which counter forces that occur when the prototype is tilted and accelerated in different directions. To measure these movements, an IMU sensor containing both an accelerometer and a gyroscope was used. This sensor was placed in the center of rotation to increase sensor accuracy. To relate the input signal from the sensor to the output signal to the motors, a PIDcontroller was used. It was studied whether mathematical modelling or experimental testing provided the best method to determine the parameter values for this PID-controller. To test the performance, data about acceleration and relative angle to the acceleration resultant was gathered. This showed how high accelerations the system could handle, to evaluate if the system could be used in a restaurant or a bar environment. It also showed how much the platform was tilting in relation to the acceleration resultant, which determines if the liquid would stay in the glass. Additionally, a survey was created to gather opinions regarding robots in a restaurant or bar environment. The implementation is deemed possible and the survey showed that there is a great interest for this product. A clear majority answered that they would be attracted to a restaurant or a bar with robotic waiters. The study of three different ways to apply the derivative part of the PIDcontroller concludes that the use of the gyroscope was the best for this application, despite its inability to react on acceleration from linear motion. Experimental testing proved most time efficient to determine the parameter values for the PID-controller, but the non-linearized mathematical model of the system that is presented could well serve as a foundation to further improve this controller.Detta projekt fokuserar på balanseringen av ett dryckesglas, för att kunna transportera detta utan att innehållet spills ut. Designen är främst tänkt för att ersätta en servitör i restaurangverksamhet, men teknologin kan väl appliceras till mobila dryckeshållare i exempelvis bilar och båtar. Kärnan i projektet är att studera hur och om det är möjligt att skapa en plattform som klarar av att balansera ett dryckesglas när den utsätts för olika accelerationskrafter. Denna rapport beskriver ett sätt att gå tillväga för att konstruera denna dryckeshållare, med förklaringar om hur hårdvaran har designats och satts ihop samt hur mjukvaran fått komponenterna att fungera tillsammans. Målet var att vrida plattformen så att accelerationsresultanten alltid var riktad längs sensorns z-axel. Balanseringen delades upp i två separata system som reglerar varsin rotation kring två vinkelräta axlar. Rotationen drivs av två DC-motorer, som motverkar de krafter som uppstår när testplattformen vinklas och accelererar i olika riktningar. För att mäta dessa röresler användes en IMU-sensor som innehöll både accelerometer och gyroskop. Sensorn var placerad i rotationscentrum för att öka precisionen i mätningarna. För att relatera insignalen från sensorn till utsignalen till motorerna användes en PID-kontroller. Det undersöktes om matematisk modellering eller experimentell testning gav den bästa metoden att bestämma parametrarvärdena till denna PID-kontroller. För att testa prestationsförmågan samlades accelerationsdata samt data om den relativa vinkeln till accelerationsresultanten. Detta visade hur höga accelerationer som systemet klarade att hantera, för att utvärdera om systemet kunde användas i en restaruang- eller barmiljö. Det visade även hur mycket plattformen lutade relativt accelerationsresultanten, vilket avgör om vätskan stannar i glaset. Till detta gjordes också en undersökning för att samla in åsikter om robotar i restaurang- eller barmiljö. Implementationen av denna robot bedöms möjlig och det finns ett intresse för en sådan produkt. En klar majoritet av de tillfrågade svarade att de skulle vara lockade till en restaurang eller bar med robotservitörer. Vid undersökningen av tre olika sätt att applicera den deriverande delen i PID-kontrollern drogs slutsatsen att användadet av gyroskopet var det som fungerade bäst i tillämpningen, trots att den inte kan ta hänsyn till acceleration från rätlinjig rörelse. Experimentell testning visade sig vara mest tidseffektivt för ta fram parametervärdena till PID-kontrollern, men den presenterade icke-lineariserade matematiska modellen av systemet kan väl utgöra en grund för att förbättra denna kontroller.

In the Wairau Valley 40 km southwest of Blenheim, elevated salinities are present in the groundwater below a depth of approximately 15 m, to the north of the Wairau Fault. Saline water is present very close to the surface between the Southern Hills and the Wairau Fault. Highest concentrations are located in well O28/w/0219 with total dissolved solids concentrations approximately 31,000 mg/L. Only a few wells in the study area have intercepted the saline groundwater. A report by Taylor (2003) has identified the groundwater below the Holocene terrace surface is recharged from Southern Hills runoff, however the Wairau Fault has a significant impact on the groundwater flow on the south bank acting as a semi-permeable barrier to groundwater flow from the southern Hills streams identified by several spring which emerge on the fault trace. The scope of this investigation was to identify the extent of the saline groundwater in the Homelands area and to attempt to define the origin of the highly saline groundwater. Furthermore, to define the groundwater flow path below the upper terrace surface to recharge the Wairau Valley Aquifer. The Multi-Electrode Resistivity technique was used to define the extent of the saline groundwater. This shows the saline groundwater is ubiquitous at depth in the study area. The depth to the freshwater/saline water interface varies laterally in the resistivity profiles. A major control on the presence of the groundwater salinity is considered to be the permeability of the gravel. Gravels with a higher permeability are probably washed of any residual salinity that may have been present in the past. Investigations into the origins of the saline groundwater were completed using stable isotope analysis (¹⁸O, ²H, and ¹³C), hydrochemistry and age dating techniques (³H and ¹⁴C). Due to the complex chemistry a single source could not be identified, however two methods were identified as the most likely. This was evaporative concentration of fresh water in the Wairau Valley, or the upward migration from the Wairau Fault of formation water probably of seawater origin. The stable isotope data fits best with an evaporative concentration of freshwater within the Wairau Valley, however, ratios of chemical constituents are very similar to other formation waters found in other parts of the world. Stream gauging of streams on the south bank show no significant water loss in the reaches north of the Wairau Fault. Therefore, recharge must be crossing the Fault trace as groundwater. Boundary Creek looses all of its surface flow for most of the year upon reaching the valley floor. Bounday Creek has washed out sections of the Wairau Fault and Major terrace riser between Wr 1 and Wr 2 terrace surfaces. It is proposed that groundwater flowing in the gravels reworked by Boundary Creek is the major recharge source for the Wairau Valley Aquifer.

A quantitative understanding of the processes controlling sediment transport and deposition across the land/sea interface is crucial to linking terrestrial and marine environments and understanding the formation of marine stratigraphy. The nature and distribution of terrestrial-derived sediment preserved in shelf stratigraphy in turn provides insight into the complex linkages inherent in source-to-sink sediment dynamics. Located inboard of an actively subducting plate boundary and characterized by one of the highest sediment yields in the world, the open-shelf setting off of the Waiapu River in New Zealand presents an excellent location to improve our understanding of the factors controlling the formation of continental shelf stratigraphy and associated sediment transport. Over 850km of high-resolution seismic and swath bathymetry data ground-truthed by cores show significant stratigraphic spatial variation preserved on the Waiapu continental shelf. This spatial variation is likely controlled by regionally-specific sediment deposition and resuspension processes as well as antecedent geology. Chronostratigraphic control obtained from black carbon analysis reveals that deforestation of the Waiapu catchment is preserved as a distinct event in the adjacent inner shelf stratigraphy, and further indicates that the inner shelf is currently capturing a significant ∼16-34% of the total Waiapu sediment budget. Shelf-wide stratigraphy shows that the thickest deposits of Holocene stratigraphy are found in tectonically-created accommodation spaces, highlighting the role of neotectonics in strata formation. The primary control on strata formation on the Waiapu continental shelf is presumed to be tectonically-steered, local sediment supply, which likely still influences modern-day sediment transport via the effects of small-scale bathymetric lows steering gravity-dependent sediment flows at the river mouth.

The aim of this dissertation is to analyze a group of Brazilian workers who are in London doing some "unskilled job" in the service sector. It is intended to verify: the alleged reasons to migrate; how it developed throughout the process of displacement, arrival and adaptation in the new society; the working conditions that these immigrants are submitted; the social networks used to obtain and maintain the work; and the intra-Community relations. In a context of mobility of people between continents and region, social networks act as mediators that facilitate these movements, since the social contacts provide initial information to obtain access to housing, work and other material or symbolic goods. However, those individuals who "constitute social ties" are not always supportive and these links will not provide gains to all, and it may exclude some while includes others. Inserted into a new social logic and working on activities that they would not perform in their country of origin, these immigrants assume new values in relation to work, building new forms of social differentiation and justification. The research is the result of two distinct moments. First an exploratory study was conducted from an experience as student and casual worker for nine months in London, in which was developed ethnography of social relations and work in the "community" of informal Brazilian workers. Secondly, in-depth interviews were conducted in order to recover the trajectory of life of these migrant.
O objetivo desta dissertação é analisar um grupo de trabalhadores brasileiros que estão em Londres realizando trabalhos considerados desqualificados dentro do setor de serviço. Pretende-se verificar os motivos alegados para migrar, a forma como se desenvolveu todo o processo de deslocamento, chegada e adaptação na nova sociedade, as condições de trabalho a que se submetem esses imigrantes, as redes sociais utilizadas na obtenção e manutenção do trabalho, e as relações intracomunitárias. Em um contexto de crescente deslocamento de indivíduos entre regiões e continentes, as redes sociais funcionam como mediadores que facilitam esses deslocamentos, já que os contatos sociais fornecem as informações iniciais para se obter acesso à moradia, trabalho e a outros bens materiais ou simbólicos. Contudo, nem sempre esses indivíduos que constituem laços sociais são solidários e nem sempre esses laços vão proporcionar ganhos a todos, podendo excluir alguns ao mesmo tempo em que incluem outros. Inseridos em uma nova lógica social e trabalhando em atividades que não realizariam em seu país de origem, esses imigrantes assumem novos valores em relação ao trabalho, construindo novas formas de diferenciação e justificação social. A pesquisa é fruto de dois momentos distintos. Primeiro foi realizado um estudo exploratório, a partir de uma experiência como estudante e trabalhador informal durante nove meses, na cidade de Londres, na qual foi desenvolvida uma etnografia das relações sociais e de trabalho na comunidade de trabalhadores informais brasileiros. Num segundo momento, foram realizadas entrevistas em profundidade com o intuito de recuperar a trajetória de vida desses trabalhadores migrantes.

Every day, millions of people set long-term goals, such as learning a skill, developing a habit, or completing a project. Yet, in our busy, time-crunched world, most have difficulty making progress towards these goals. Despite this lack of time, there are numerous moments in a day when people wait, such as waiting for the elevator or waiting for an instant message reply. These fleeting moments could instead be used for completing short, concrete microtasks towards accomplishing long-term goals. This thesis presents novel systems and approaches that enable wait-time productivity. First, WaitChatter enables wait-learning, by automatically detecting when a user is awaiting an instant message reply, and presenting foreign language vocabulary exercises during that time. Second, WaitSuite is a suite of systems that expand wait-learning to diverse kinds of waiting scenarios. Furthermore, given a variety of microtasks, I also demonstrate how chains of microtasks can be ordered in a way that maximizes efficiency and minimizes mental workload. Finally, Deadspace Finder enables peripheral microtasks to be displayed less intrusively, by automatically detecting and placing them into unused screen space. Taken together, these systems demonstrate that wait-time productivity is both feasible and more effective than traditional reminders, making meaningful use of time we didn't know we had.

Rhizoctonia zeae is a common pathogen of tall fescue and other turfgrasses in various regions of the United States. Disease caused by R. zeae typically occurs during hot, humid summer months when conditions are ideal for growth of the fungus but less than ideal for growth of tall fescue. While R. zeae has been reported on turfgrasses in several Mid-Atlantic states, there are no records of this pathogen being present in Virginia. Rhizoctonia isolates were obtained from samples of various turfgrasses exhibiting typical Rhizoctonia disease symptoms in Virginia. Additional isolates were obtained from several other states. All were characterized with respect to species characteristics as well as pathogenicity and virulence on two common cultivars of tall fescue. All isolates were pathogenic on tall fescue but there was some variability in virulence. There was consistently slightly less disease present on Crossfire II than on Kentucky 31. Experiments were also conducted to determine the impact of prior exposure to high air temperatures on the severity of disease. Preliminary data showed that one week of exposure to higher air temperatures caused an initial increase in overall turf quality, but as length of exposure increased the quality of turfgrass declined. Tall fescue plants were subjected to 0, 7, and 35 days of heat stress prior to inoculation with several isolates of R. zeae. No relationship was found between predisposing heat stress and disease severity.Master of Science

The Waiapu River, located on the North Island of New Zealand, drains a small catchment and has one of the highest sediment yields in the world. The river delivers most of its annual sediment load during floods into energetic coastal waters. These conditions are favorable for producing multiple sediment transport mechanisms, including transport in positively and negatively buoyant freshwater plumes, gravitydriven flows, and resuspension. Analyses of Waiapu River shelf seabed data showed that multiple transport mechanisms influence strata formation. Fluvial sediments are initially deposited at water depths shallower than 80 m before being remobilized and deposited at greater water depths. Over the last 100 years fine sediments were retained mainly at water depths between 60 and 190 m, and accounted for 24% of the fluvial load. High shelf accumulation rates (0.2--3.3 cm/yr) were sufficient to preserve pulsed event layers, which were identified by low excess 210Pb and terrestrial delta 13C. Additionally, high subsidence rates on the tectonically active shelf likely influences modern depositional patterns. A three-dimensional numerical model was used to address the mechanisms by which sediment escaped the shelf and to assess the relative importance of the various transport mechanisms. The simulation was able to reproduce time-averaged currents, near-bed sediment concentrations, and bed shear stresses at a tripod deployed off the river mouth at 60 m water depth. Gravity-driven transport was most important on the inner and mid-shelf, whereas dilute transport became more important beyond 65 m depth. Sediments escaped the shelf via dilute suspension to the north of the Waiapu River mouth. Sensitivity experiments showed that transport pathways and depositional patterns were sensitive to floc fraction, waves and currents, and sediment load. Increasing the floc fraction resulted in increased wave-supported gravity-driven transport relative to dilute transport and increased shelf deposition. Coherence between energetic waves and floods increased the importance of wave-supported gravity-flows and shifted initial deposition offshore. Wave-induced bed shear stress increased gravity-driven transport, whereas current-induced bed shear stress increased dilute transport. Deforestation over the last 150 years, which has resulted in an increase annual suspended load, may have resulted in increased shelf sediment retention.

The paradigm of diffusion research can be traced back all the way to the 1940s when Ryan and Gross investigated the diffusion of hybrid seed among farmers in Iowa. Since the 1960s diffusion research has been applied in a wide variety of disciplines, for instance, to study the diffusion of the Internet and the non-diffusion of the Dvorak keyboard. Currently, the technologies that are on top of the Gartner Hype Cycle are all associated with Artificial Intelligence (AI), which shortly can be defined as learning devices that perceive their environment and take actions to maximize their success at some goal. Consequently, some people suggest that the current hype surrounding AI can be the end of the human kind, while others believe it will give way for millions of fresh jobs and cleverer decision-making. In recent years both media and political organizations have shown great interest in AI. In addition, the industry is captivated by the potential uses of AI. In the last years, AI-related companies in the US have raised billions of dollars in the stock market together with a large number of acquisitions. The large flow of capital into AI technology underpins the fast development of AI solutions. The purpose of this study is to investigate how groups approach AI. What can be concluded after reviewing different sectors is that organizations seem to share a common interest of AI. Furthermore, organizations share the opinion that eventually AI will be a more natural part of their processes. Organizations investing a larger share of their budget in R&D have a longer experience of using AI and are currently doing projects utilizing more advanced technologies within AI. In organizations from other sectors, the investments in AI depend on the people with the authority to invest money in projects and their view on AI. Organizations generally seem to approach AI in a similar way. Firstly, they evaluate what AI is. Secondly, they find areas to make small iterative PoC-projects utilizing AI, usually with machine learning. Finally, more money is invested if the PoC-projects were successful and the organization starts looking at how to acquire more competence within the area to fully exploit the value of AI.Paradigmet för innovationsspridning kan spåras ända tillbaka till 1940-talet när Ryan och Gross undersökte spridningen av hybridfrön bland bönder i Iowa. Sedan 1960-talet har forskningen tillämpats inom en mängd olika discipliner, till exempel för att studera spridningen av Internet och icke-spridningen av Dvorak-tangentbordet. För närvarande är teknologierna som ligger på toppen av Gartner Hype-cykeln alla förknippade med artificiell intelligens (AI), som kan definieras som lärande enheter som uppfattar sin miljö och vidtar åtgärder för att maximera sin framgång gällande något mål. Hypen som nu finns kring AI har lett till att vissa människor tror att det kan innebära slutet för mänskligheten medan andra tror att det kommer att ge plats för miljoner nya jobb och smartare beslutsfattande. Under de senaste åren har både medier och politiska organisationer visat stort intresse för AI samt visat intresse för potentiella användningsområden av AI. AI-relaterade företag i USA har under de senaste åren har tagit in miljarder dollar i riskkapital. Ett stort antal förvärv och kapitalflödet till AI-teknik ökar den snabba utvecklingen av AI-lösningar. Syftet med denna studie är att beskriva spridningen av AI i organisationer från ett antal olika sektorer. Vad som kan sägas efter att ha studerat olika sektorer är att organisationer delar en gemensam nyfikenhet för AI och att de tror att AI kommer bli en allt mer naturlig del av sina processer. De företag som spenderar mycket pengar på FoU har längre erfarenhet av att använda AI och gör för närvarande projekt som använder mer avancerade tekniker. I andra organisationer är investeringarna inom AI beroende av de anställda som har rätt att investera pengar i projekt och deras syn på AI. Organisationer verkar allmänt närma sig AI på ett liknande sätt där de först utvärderar vad AI är. Därefter väljer de ett antal områden där de gör små iterativa projekt där de utnyttjar AI, vanligtvis via ML. Därefter investerades mer pengar om de små projekten lyckas och företaget börjar titta på hur man kan förvärva mer kompetens inom området.

Currently, most computer systems are running on multiprocessors (or multicores). Moreover, the number of cores inside the processor are expected to increase. To be able to utilise the increased computational power in these systems, developers are enforced to expose more parallelism within their applications. Multi-threading is one of the common techniques that are used to introduce parallelism within computer applications. Shared data structures are in the core of multi-threaded applications; these data structures facilitate the communication between the different threads to help in completing the designed tasks within the application. A control mechanism should be provided such that the access of any thread will not compromise the consistency and correctness of the data structure contents. The increased number of threads will result in an increased competition, this will lead to inevitable difficulties in understanding the interleaving scenarios at runtime, hence, the time analysis will be a very complex task. The Real-Time Specification for Java (RTSJ) introduces different shared queues that can facilitate communication between different threads within the application. However, these queues are uni-directional enabling communication between standard Java threads and the realtime thread classes, which the RTSJ introduces. The work presented in this thesis introduces a novel algorithm for concurrently accessing shared data structures in a shared memory multi-processor (or multi-core) systems. The proposed algorithm is implemented as an arraybased First-In-First-Out (FIFO) queue, which improves the scalability and time predictability in multi-threaded applications. The algorithm utilises the different features that the RTSJ introduces to ensure the time predictability.

The North Bank area lies on the north side of the Wairau River, Marlborough, New Zealand, bounded by the Richmond Ranges to the north and the Wairau River to the south. The North Bank is an interactive zone where groundwaters and surface waters from North Bank tributary valleys mix with waters of the Wairau River. This investigation aimed to define the nature and origin of groundwaters of the North Bank area.
Stable isotopes of oxygen and hydrogen, along with hydrogeochemistry, were utilised in order to define the spatial extent of the North Bank riparian margin and delineate the Wairau River-groundwater interface. Distinct stable isotopic signatures differentiate ground and surface waters that come from high mountain catchments versus those that arrive more locally at lower altitude. The results gathered by this study demonstrated stable isotopes to be the most powerful forensic tool capable of distinguishing Wairau River water from North Bank tributary groundwater sources. In contrast, hydrogeochemical characteristics of the waters of the North Bank were young and chemically dilute in nature, which made them chemically indistinguishable from waters of the Wairau River.
Geomorphological mapping was conducted in order to investigate the relationship between groundwater flow patterns and geomorphology upon the North Bank. Geomorphology, in the form of prominent fluvial terraces, was found to play a role in limiting the extent of Wairau River influence to groundwater to either low-lying Q2 Speargrass Formation, Q1 Rapaura Formation alluvium or the Wairau River channel itself.
Aquifer pump testing and water level observation carried out in the Waikakaho Valley revealed a plentiful groundwater resource in the local context. Like other tributary valleys within the North Bank study area, surface water and groundwater were found to be chemically and isotopically linked to one another which points to an interconnected ground and surface water resource, larger than first thought. Driven by recharge by the Waikakaho River, the groundwater resource has development potential, and continued monitoring will further define the hydrogeological system and ensure long term sustainable use.

The Wairau Fault, the northern extension of the Alpine Fault, has not ruptured historically. Bounding the Marlborough Fault System to the north the Wairau Fault is over 100 km long and capable of generating a large earthquake rupture. From Cloudy Bay SW to Lake Rotoiti the fault is defined by a linear valley-bound trace and narrow zone of deformation. The main objective of this paleoseismic investigation of a section of this fault was to establish the pre-historic rupture history.
Trenching excavations, geomorphic mapping, differential GPS surveying and weathering rind dating techniques were used to investigate the rupture history of the Wairau Fault.
From trenching data at Tophouse, one earthquake rupture on the Wairau Fault is recorded since AD 200. No upper limit bounds this rupture date. Integration with a similar paleoseismological study of Zachariasen et al, (2001) refines the last rupture event on the Wairau Fault to between AD 200 - 1000. A branch caught in the shear zones indicates a dated event approximately 12 500 years ago but other events intervene on stratigraphic evidence. Liquefaction deposits are recognised in the trenches, in conjunction with small thrust flaps on the footwall side, suggesting seismic rupture as the dominant translation mechanism, with no significant aseismic creep based on offset linear terraces.
Dextral slip rates on the fault of 4.2 ± 1.4 mm/yr compares well with pre-existing data. A single event offset of 4.4 ± 0.5 m is consistent with others further NE along the Wairau Valley.
A temporal disparity exists between the last rupture brackets at the Tophouse and Matakitaki River trenches (Yetton, 2002), indicating that, at least for the last rupture event an earthquake segment boundary was operational between the two trench sites. Defining an earthquake rupture segment boundary by a specific structure or location is difficult as any number of faults could dissipate radiated seismic energy and several possibilities are reviewed. If a rupture segment does exist between Matakitaki River and Tophouse, it is most likely about Lake Rotoiti. An estimated earthquake magnitude for the onland section of the Wairau Fault for this rupture segment is M = 7.4 ± 0.25.
In addition to aspects of seismicity of the fault strike, both the large scale topographic setting and detailed morphology of the fault zone are discussed. In particular the complexity of interaction between fluvial processes and secondary deformation associated with the fault zone has lead to some insights into both the evolution of secondary structures and to the response of rivers behaviour to seismic cycles.
On the basis of elapsed time since the last fault rupture, and slip rates on the fault, an earthquake rupture on the Wairau Fault in the near future is a distinct possibility.

This thesis presents a component-based approach to proving the correctness of programs involving pointers. Unlike previous work, our component-based approach supports modular reasoning, which is essential to the scalability of systems. Specifically, we specify the behavior of a graph-marking algorithm known as the Schorr-Waite algorithm, implement it using a component that captures the behavior and performance benefits of pointers, and prove that the implementation is correct with respect to the specification. We use the Resolve language in our example, which is an integrated programming and specification language that supports modular reasoning. The behavior of the algorithm is fully specified using custom definitions, pre- and post-conditions, and a complex loop invariant. Additional operations for the Resolve pointer component are introduced that preserve the accessibility of a system. These operations are used in the implementation of the algorithm. They simplify the proof of correctness and make the code shorter.Master of Science

In this thesis, we studied the act-and-wait control mechanism on the stabilization of the inverted pendulum in both piecewise constant feedback and continuously varying feedback models.
We also extend the act-and-wait control mechanism with a more general model: the act-and-wait control with frequently varying feedback, which includes piecewise constant feedback and continuously varying feedback as two of its extreme cases. The frequently varying feedback model is valuable in approximating the continuously varying feedback system when the delay is large. The modeling error is discussed in the comparison of piecewise constant feedback and continuously varying feedback. The robustness of the three models are studied in the context of the parametric stability regions as well as for the interaction of delay and noise. We discovered that although act-and-wait control can stabilize the pendulum system even with large delay, the robustness is impaired by large delays. As a result, the piecewise constant feedback system is more sensitive to parametric noise than the frequently and continuously varying feedback models. The interplay of act-and-wait control and external noise leads the system to a periodically varying density for its state.Science, Faculty of

The estimation results of Brazilian risk premia are not robust in the literature. For instance, among the 133 market risk premium estimates reported on the literature, 41 are positives, 18 are negatives and the remainder are not significant. In this study, we investigate the grounds for this lack of consensus. First of all, we analyze the sensitivity of the US risk premia estimation to two relevant constraints present in the Brazilian market: the small number of assets (137 eligible stocks) and the short time-series sample available for estimation (14 years). We conclude that the second constrain, small T, has greater impact on the results. Following, we evaluate the two potential causes of problems for the risk premia estimation with small T: i) small sample bias on betas; ii) divergence between ex-post and ex-ante risk premia. Through Monte Carlo simulations, we conclude that for the T available for Brazil, the betas estimates are no longer a problem. However, it is necessary to wait until 2041 to be able to estimate ex-ante risk premia with Brazilian data.Os resultados das estimações de prêmios de risco brasileiros não são robustos na literatura. Por exemplo, dentre 133 estimativas de prêmio de risco de mercado documentadas, 41 são positivas, 18 negativas e o restante não é significante. No presente trabalho, investigamos os motivos da falta de consenso. Primeiramente, analisamos a sensibilidade da estimação dos prêmios de risco norte-americanos a duas restrições presentes no mercado brasileiro: o baixo número de ativos (137 ações elegíveis) e a pequena quantidade de meses disponíveis para estimação (14 anos). Concluímos que a segunda restrição, T pequeno, tem maior impacto sobre os resultados. Em seguida, avaliamos as duas potenciais causas de problemas para a estimação de prêmios de risco em amostras com T pequeno: i) viés de pequenas amostras nas estimativas dos betas; e ii) divergência entre prêmio de risco ex-post e ex-ante. Através de exercícios de Monte Carlo, concluímos que para o T disponível no Brasil, a estimativa dos betas já não é mais um problema. No entanto, ainda precisamos esperar até 2041 para conseguirmos estimar corretamente os prêmios ex-ante com os dados brasileiros.

This thesis investigates whether variations in wait times for different medical specialties have a significant impact on the proportion of people who choose to opt out of the public insurance system in their country. Canada presents an interesting case study because it is one of the few nations with a single-payer system for all procedures covered by the public health system. As a result, leaving Canada is the equivalent of opting into the private system in other countries where socialized medicine is available side by side to a private market provider. The results provide some evidence of a positive relationship, but are somewhat sensitive to the chosen sample period.

Thesis(MA)--Stellenbosch University, 2014.ENGLISH ABSTRACT; In order for the transformation objectives of racial and gender diversity to be adequately reflected in the South African medical profession, it is crucial to understand how Black medical registrars experience the training environment. This qualitative study presents the experience of ten Black African medical specialists who completed their registrar training in the Western Cape in the past five years. Using both thematic and discourse analysis the study aimed to identify and describe the interpersonal, structural and institutional factors that may impede or promote Black advancement during registrar training. Participant experiences where contextualised in relation to discourses around the medical profession as a site of cultural reproduction that has been historically constructed as the exclusive domain of the White male. The analysis unearths experiences of systemic racism where the organisational culture of training institutions is experienced as alienating and unwelcoming to Black professionals. The findings raise the need for a more thorough evaluation of how transformations efforts are being received in specialist medical education. Key Words: Black doctors, Transformation in Higher Education, Systemic Racism, Medical training

Повний текст джерелаАнотація:
The Waiapu River drains a small mountainous basin, characterized by steep terrain, heavy rainfall, and unconsolidated soft Tertiary mudstone and siltstone. These factors, combined with heavy deforestation over the past 100 years have created one of the world's highest sediment yields. Water discharge of the Waiapu River is very episodic over both inter- and intra-annual timescales, and almost all of the discharge is associated with floods brought by cyclonic storms. The Waiapu River drains an active margin that has a narrow shelf and steep slope. Marine conditions on the Waiapu continental shelf are very energetic, with strong waves as well as shelf currents. This special river-ocean system makes the Waiapu area an ideal site to study gravity-driven flows. Instrumented tripods deployed at water depths of 40 m and 60 m on the Waiapu shelf directly offshore of the river mouth recorded data on waves, currents, and sediment fluxes from May through August, 2004. The tripod data showed direct field evidence of current-supported gravity flows on the Waiapu shelf. Data analysis indicated that the Waiapu River floods were characterized by two distinct phases: a flood phase and a resuspension phase. The flood phase was characterized by large sediment input, coupled with moderate to strong waves but weak currents. Strong near-bed sediment signals, however, were not recorded by the tripods until the post-flood resuspension phases, during which seaward near-bed currents started to intensify. A one-dimensional boundary layer model provided the inference that those strong seaward near-bottom turbid flows during the resuspension phase were dynamically similar to wave-supported gravity flows observed on Eel and Po Shelves, except that both waves and currents were important for sediment resuspension. In contrast to thin and dense wave-supported gravity flows, current-supported gravity flows on the Waiapu shelf were significantly thicker and more dilute. Another two-dimensional model for wave- and current-supported sediment gravity flows was used to estimate sediment deposition on the Waiapu shelf from September 2003 to August 2004. The time period for the model calculations was divided into two segments: a low-energy (September to May) and high-energy portion (May to August). Model results showed that sediment delivered by the Waiapu River were trapped between the 20- and 80-m isobaths during the low-energy period, but then redistributed obliquely across the shelf between the 60- and 120-m isobaths during the high-energy period. Depositional locations estimated for the low- and high-energy portions, respectively, matched well with short- and long-term observed accumulation patterns based on 7 Be and 210Pb activity as reported by Kniskern (2007; Kniskern et al. 2008). Sensitivity analysis indicated that the gravity-driven flows on the Waiapu shelf were mainly wave-supported landward of the 40-m isobath, but became increasingly current-supported as wave orbital decayed in deeper water. This dissertation provided the first documentation of current-supported gravity flows, and hence contributed greatly to the study of sediment transport on continental shelves.

Deadlock analysis of object-oriented programs that dynamically create threads and objects is complex, because these programs may have an infinite number of states.
In this thesis, I analyze the correctness of wait - notify patterns (e.g. deadlock freedom) by using a newly introduced technique that consists in an analysis model that is a basic concurrent language with a formal semantic. I detect deadlocks by associating a Petri Net graph to each process of the input program. This model allows to check if a deadlock occur by analysing the reachability tree.
The technique presented is a basic step of a more complex and complete project, since in my work I only consider programs with one object.

This thesis deals with the structure of the no-wait job-shop problem as well as the derivation of fast approximation algorithms. These algorithms are based on a decomposition approach into a sequencing and a timetabling problem that was initially introduced by Macchiaroli et al. (1999). In the thesis the problems are derived from a mixed integer formulation of the original problem and proved to be NP-hard in the strong sense. After presenting a fast heuristic approach for the timetabling problem, the focus lies on the sequencing problem for which several local search algorithms are presented. The algorithms are tested on a wide variety of benchmark problems for the classical job-shop problem. Among the algorithms, the tabu search approach outperforms all other algorithms that can be found in the literature in objective value as well as computation time.
