Abstract:
The determination of the individual characteristics of the fatigue resistance of the objects is proposed using fractographic analysis of their fractures, which gives an approximate estimate of the voltage corres-ponding to one cycle and allows one to construct an oblique portion of the fatigue curve from the test of one object and calculate the endurance limit from the Weibull equation.

Abstract:
The main application of collaborative robots is helping workers during assembly tasks. Most assembly task robots are limited to fixed scenarios that do not require reasoning. To address the current limitations, this thesis introduces a goal-directed dynamic AI system that enables robots to help workers during assembly tasks. After observing an object being assembled, our AI system can induce a 3D model of the assembled object. This induced model encodes the spatial relationships between the components of the object and allows a dynamic planner to repair assembly plans when the worker deviate from the initial plan.

Full text
Abstract:
This three-part thesis reviews the effectiveness of psychological interventions for chronic non-cancer pain on healthcare use and sick leave from work, and explores the process of change in a pain management programme using single case methods. Part 1 is a meta-analysis of 16 randomised controlled trials of psychological interventions in a chronic pain population. Small to moderate effect sizes were found for reduced healthcare use but no significant benefit for sick leave. Part 2 is a study using single case design methodology to explore trajectories of change in 8 patients attending a CBT-based chronic pain management programme. Baseline, intervention and bi-weekly follow-up self-report of catastrophic thinking, mood, self-efficacy, and goal attainment, and of process variables of working alliance and adherence, were supplemented by a post treatment change telephone interview which was qualitatively analysed. Detailed examination of change for each participant provided rich data: three participants improved significantly over the course of the programme, three deteriorated, and all improved in at least one goal. Therapeutic alliance was high and participants rated central elements of the programme, explanations of their pain, and peer support/group membership as important. Part 3 is a critical appraisal of the study and the review, contrasting the approaches, and concluding with a personal reflection on the process.

Full text
Abstract:
Single-party dominance (SPD) is a phenomenon that has puzzled many scholars within the field of political science, as it does not fit into the standard dichotomy of democracy versus dictatorship. Kenneth Greene’s Resource Theory seeks to explain prolonged electoral dominance in these systems by looking at resource asymmetries between the governing party and the opposition. Greene applies his theory to democratic and non-democratic SPD systems alike. In order to expand knowledge in the field of SPD research, this thesis has provided a critical analysis of Greene’s theory using South Africa under the ANC within the timeframe of 1994 to February 2018 as an illustrative case. The thesis concluded that the Resource Theory could not be used for explaining ANC dominance, and indicated that resources have a limited power to explain SPD. As such, the aim of the thesis is to uncover theoretical weaknesses of the theory. Firstly, it is argued that the theory is weakened by the use of subjective and sometimes arbitrary concepts which hamper testability. The main theoretical flaw identified is Greene’s assumptions of the nature of such systems, in which he sees the dominant party as one unit. I argue in this research that this assumption renders the theory unable to predict the consequences of factionalisation within the dominant party. Three main factors are identified to justify why resources have limited explanatory power. Firstly, factionalisation leads to intra-party competition for state resources, and these factions become dependent on a steady stream of resources to sustain themselves. This competition can become so fierce that the economy suffers. When resources become less available, these conflicts intensify. Consequently, the dominant party starts deteriorating from within and misconduct can no longer be concealed from the public. As the government becomes less responsive in terms of providing public goods in combination with increased public awareness, voter dissatisfaction also intensifies. This eventually leads citizens to abandon their allegiance to the party. The research study shows that resources are not independent from external and internal environments, indicating that asymmetric resource advantages alone cannot explain why these systems exist over longer periods of time.

Political Science
Ph.D.
As international pressure for multiparty reforms swept Africa during the early 1990s, long-time incumbent, such as UNIP in Zambia, KANU in Kenya, and the MCP in Malawi, were simultaneously challenged by widespread domestic demands for multiparty reforms. Only ten years later, after succumbing to reform demands, many long-time incumbents were out of office after holding competitive multiparty elections. My research seeks an explanation for why this pattern did not emerge in Tanzanian, where the domestic push for multiparty change was weak, and, despite the occurrence of three multiparty elections, the CCM continues to win with sizable election margins. As identified in research on semi-authoritarian rule, the post-reform pattern for incumbency maintenance in countries like Togo, Gabon, and Cameroon included strong doses of repression, manipulation and patronage as tactics for surviving in office under to multiparty elections. Comparatively speaking however, governance by the CCM did not fit the typical post-Cold-War semi-authoritarian pattern of governance either. In Tanzania, coercion and manipulation appears less rampant, while patronage, as a constant across nearly every African regime, cannot explain the overwhelming mass support the CCM continues to enjoy today. Rather than relying on explanations based on repression and patronage alone, I locate the basis of post-reform CCM dominance in a historical process whereby a particularly unique array of social and economic policies promulgated during single-party rule culminated in comparatively affable social relations at the onset of multiparty reform. In Tanzania, this post-independence policy mix included stemming the growth of vast regional wealth differentials, a rejection of ethnicity as a basis for organizing collective action, and the construction of a relatively coherent national identity. By contrast, in most other African cases, policies under single-party rule acted to reinforce many of those economic and ethnic divisions inherited at independence. These divisions in turn, acted as material and moral capital for organizing dissent against incumbency, and the consolidation of opposition parties following political reform.

Full text
Abstract:
How to explain political monopolies in democratic institutional settings? Dominant parties in countries with robust formal democratic institutions are surprisingly frequent, yet poorly understood. Existing theories explain away the puzzle by characterizing dominant parties as `catch-all' parties that survive on the basis of historically imbued mass voter legitimacy. This dissertation develops a theory of how dominant parties in fact routinely win free and fair elections despite counter-majoritarian policy biases and why they decline, utilizing the uneven decline of single-party dominance across regions and localities of India as a historical natural experiment. The puzzle in the Indian case is that the Congress party was able to monopolize power in a poor and rural society for over four decades after independence despite a counter-majoritarian urban bias and free and fair elections. The dissertation develops a political economy model that rationalizes this --- showing how extensive but implicit ties of patronage enable dominant parties to maintain power and counter-majoritarian policies in conditions of formal democratic institutions. The theory generates two new empirical implications about why dominant parties decline and how this reshapes distributive politics --- which are tested through sub-national comparative historical analysis, quantitative analysis of historical data, and in-depth fieldwork. First, the theory suggests that dominant parties do not simply fade away with the passage of time or societal modernization, but decline as a result of protracted distributive conflict with rising but politically excluded economic interests. In the Indian context, I provide evidence that this took the form of political mobilization by agricultural producers in the aftermath of the green revolution. Exploiting exogenous variation in the diffusion of high-yielding variety crops, the first empirical chapter provides evidence that economic growth in the politically excluded agricultural sector intensified rural-urban distributive conflict, accounting for the rise of agrarian opposition parties and half of the Congress party's long-run decline. Second, the theory suggests that the decline of single-party dominance democratizes distributive politics, in two ways. One is that policies shift in favor of the rising but previously politically excluded economic interests. Another more complex channel is that in an effort to regain lost political ground, dominant parties strategically reinvent themselves as pro-poor parties, initiating a process of competitive credit claiming for social policy. The second empirical chapter applies a structural break methodology to estimate the timing of dominant party decline across Indian states, and utilizes this variation to show that the decline of single-party dominance led to the rise of agriculture-favoring policies and social spending. Through fieldwork in two states as well as analysis of the electoral effects of India's largest contemporary social program, the third empirical chapter provides micro-level evidence that the emergence of a nascent welfare state is driven by a logic of competitive credit-claiming. In contrast to existing theories, the case of India suggests that dominant party decline in democratic settings bears a resemblance to the decline of political monopolies generally, representing a process of de facto democratization in de jure democratic institutional settings. I show that the argument can help to explain trajectories of dominant party decline and distributive politics in a number of other cases, including Japan, Italy, Mexico and the American South.

Abstract:
Modeling articulated objects made of rigid layered parts used to populate 3D scenes in video games or movie production is a complex and time-consuming task for digital artists. This work proposes a sketch-based approach to efficiently model 3D layered articulated objects, such as animals with rigid shells and armors, in annotating a single 2D photo manually, and eventually fabricate it from automatically computed 2D patterns. In considering symmetrical objects seen under a 3/4 view, and an- notating salient features such as extremities of the rigid articulated parts as a mix of circular and Bézier curve, this approach is able to retrieve depth information, hidden parts, and rotation-articulated structure. The resulting shape consists of a set of quadrangulated polygons that may be flattened in 2D. Details such as ears, tails, and legs were further models using dedicated annotations. The accuracy of the reconstruction has been validated on synthetic cylindrical examples, and its ro- bustness in reconstructing a 3D model of armor, armadillo, and shrimp. The latter was finally fabricated using paper.
Att modellera artikulerade objekt gjorda av styva delar lagda i lager som används till att fylla 3D-scener i datorspel och filmskapande är en komplex och tidsödande uppgift för digitala konstnärer. Den här undersökningen föreslår ett skiss-baserat tillvägagångssätt att effektivt modellera artikulerade 3D-objekt lagda i lager, såsom djur med styva skal och rustning, i att annotera ett 2D-foto manuellt, och eventuellt skapa det från automatiskt beräknade 2D-mönster. Hänsyn är tagen till symmetriska objekt sedda under en 3/4 vy, och annotera framträdande egenskapersåsom extremiteter av de styva artikulerade delarna som en blandning avcirkulära och Bézier-kurvor, kan det här tillvägagångssättet hämta information om djup, gömda delar och rotations-artikulerade strukturer. Den slutliga formen består av ett set av fyrsidiga polygoner som kan bli tillplattade i 2D. Detaljer såsom öron, svansar och ben där framtida modeller använder dedikerade annotationer. Noggrannheten av rekonstruktionen har blivit validerad på syntetiska cylindriska exempeloch dess robusthet i att rekonstruera en 3D-modell av en rustning, ett bältdjur och en räka. Den senare skapades slutligen med hjälp av papper.

Abstract:
AbstractAscidians are sessile tunicates, that is, marine animals belonging to the phylum Chordata and considered the sister group of vertebrates. They are widespread in all the seas, constituting abundant communities in various ecosystems. Among chordates, only tunicates are able to reproduce asexually, forming colonies. The high regenerative potentialities enabling tunicates to regenerate damaged body parts, or the whole body, represent a peculiarity of this taxon. Here we review the methodological approaches used in more than a century of biological studies to induce regeneration in both solitary and colonial species. For solitary species, we refer to the regeneration of single organs or body parts (e.g., siphon, brain, gonad, tunic, viscera). For colonial species, we review a plethora of experiments regarding the surgical manipulation of colonies, the regeneration of isolated colonial entities, such as single buds in the tunic, or part of tunic and its circulatory system.

Abstract:
One of the major drawbacks of single-point incremental forming process for sheet metal (SPIF) consists in the poor geometrical accuracy of formed parts. This limits the use of SPIF technology and has pushed the development of alternative incremental processes—such as the two-points incremental forming—aimed at improving the forming accuracy. However, these processes require the use of supporting dies and they therefore reduce the competitive advantage of SPIF process. The possibility to compensate for part springback, in order to have the part geometry as close as possible to the nominal one, represents one of the major challenges to make SPIF process suitable for real industrial applications. However, any possible approach in springback compensation must pass through the comprehension of the springback phenomenon. The objective of the paper is to analyze the springback of parts made by SPIF, by evaluating the influence that elastic recovery before and after the part unclamping has on the final part geometry. A SPIF experimental campaign was carried out on a truncated pyramid as case study, by varying both the part geometrical parameters (the wall angle and the height), and the process parameters (the tool step-down size and the feed rate). The material used in this study was the duplex steel DP600 provided in 0.8 mm thick sheets. After forming—but before unclamping—the part geometry was measured by means of of an electronic touch probe mounted on the machine tool-holder, in order to investigate the elastic recovery due to the successive tool laps. After unclamping, the part geometry was measured on a coordinate measuring machine. The influence of geometrical and process parameters was analyzed and the contribution of elastic recovery before and after the part unclamping was assessed.

Abstract:
Single-point incremental sheet forming processes represent today a promising alternative to traditional sheet forming operations for producing low batches or even prototypes without the use of expensive dies. Several investigations have been carried out in recent years to study the fundamental aspects of incremental sheet forming operations, with particular attention to determination of material formability. In this framework, the Authors propose to study the material tendency to be formed by incremental forming, called SPIFability, through different indicators, and to evaluate this tendency as a function of the process parameters, with particular regard to the relative velocity between the tool and the blank. Other reported studies — based on both experimental and numerical studies — have tried to give a comprehensive explanation of the deformation mechanisms that arise during incremental sheet forming, and that possibly affect the material formability. However, none of the proposed theories are today fully accepted by the scientific community. In order to study the relevant deformation mechanisms, the Authors propose to analyze the microstructural characteristics of the formed parts by means of optical microscopy and the fracture surfaces by means of scanning electron microscopy. The investigated case study is an axi-symmetric part characterized by a varying slope with depth, made from blanks of the aluminum alloy AA5182. The parts were formed on a CNC machine until the first crack appeared, and then were measured by means of a Coordinate Measuring Machine to evaluate their thickness profile and geometrical parameters.

Abstract:
As research continues into how fire department interventions affect fire dynamics in the modern fire environment, questions continue to arise on the impact and implications of interior versus exterior fire attack on both firefighter safety and occupant survivability. Previous research into various types of fire ground ventilation, flow paths, and exterior fire streams has provided the fire service with an increased understanding of fire dynamics. However, in some instances, the information from the studies did not support current, experience-based practices. This gap between the research to date and the fire ground suppression experience has driven the need for further study. This study will build upon the fire research conducted to date by analyzing how firefighting tactics, specifically different fire suppression tools and tactics, affect the thermal exposure and survivability of both firefighters and building occupants and affect fire behavior in structures. The purpose of this study is to improve firefighter safety, fire ground tactics, and the knowledge of fire dynamics by providing the fire service with scientific information, developed from water flow and full-scale fire testing, in representative single-family homes. This study will build and expand upon the fire research conducted to date by analyzing how firefighting tactics, specifically suppression methods, affect the thermal exposure and survivability of both firefighters and building occupants in addition to impacting fire behavior in structures. The purpose of this study is to improve firefighter safety, fireground tactics, and the knowledge of fire dynamics by providing the fire service with credible scientific information, developed from both water flow and full-scale fire testing, in representative single family homes. The project is comprised of 3 parts: • Part I: Water Distribution • Part II: Air Entrainment • Part III: Full-Scale Residential Fire Experiments This report details the results and analysis from the air entrainment testing. These tests were conducted without the presence of fire to gain a fundamental understanding of how hose streams entrain air. Each set of experiments was intended to add to the understanding of air entrainment and pressure from fire service hose streams by evaluating the differences caused by various application methods, hose stream types, nozzle movements, pressures/flow rates, manufacturers, and ventilation configurations.

Abstract:
Prior full-scale fire service research on the residential fireground has focused the impact of ventilation and suppression tactics on fire dynamics. This study builds upon prior research by conducting 21 experiments in two identical purpose-built single-story, single-family residential structures to quantify the impact of how search and rescue tactics are coupled with ventilation and suppression actions and timing. Each fully furnished structure included four bedrooms, 2 bathrooms and an open-floor kitchen and living room. The structures were instrumented to quantify post-ignition toxic gas and thermal conditions. Temperature, velocity, and pressure were measured to evaluate the fire dynamics. Gas concentrations and heat fluxes were measured to quantify toxic and thermal exposures. Eleven experiments examined bedroom fires, eight examined kitchen fires, and two examined living room fires. Across this series of experiments, the impact of isolation of fire and non-fire compartments, the timing of search actions relative to suppression actions, and the influence of isolation, elevation, and path of travel during rescue were examined with respect to firefighter safety and occupant tenability. Similar to previous experiments in both purpose-built and acquired structure, the data showed that prior intervention locations lower in elevation and/or behind closed doors had lower toxic gas and thermal exposures compared to locations at higher elevations or locations that were not isolated. Lower elevations were also shown to have lower toxic gas and thermal exposures during the removal of occupants as part of rescue operations. For scenarios where search operations occurred prior to suppression, isolation of spaces from flow paths connected to the fire compartment was shown to be effective at reducing the thermal operating class for firefighters and the toxic and thermal exposure rates compared to spaces that were not isolated. Following isolation, exterior ventilation was found to further reduce the toxic gas and thermal exposures in the protected space. Suppression, from either interior and exterior positions, was effective at reducing the thermal operating class for searching firefighters and the rate of thermal exposure increase to occupants. Following suppression, additional exterior ventilation increased the rate at which gas concentrations returned to pre-ignition levels.

Abstract:
Increased production rates and cost reduction are affecting manufacturing in all sectors of the mobility industry. One enabling methodology that could achieve these goals in the burgeoning “Industry 4.0” environment is the deterministic assembly (DA) approach. The DA approach is defined as an optimized assembly process; it always forms the same final structure and has a strong link to design-for-assembly and design-for-automation methodologies. It also looks at the whole supply chain, enabling drastic savings at the original equipment manufacturer (OEM) level by reducing recurring costs and lead time. Within Industry 4.0, DA will be required mainly for the aerospace and the space industry, but serves as an interesting approach for other industries assembling large and/or complex components. In its entirety, the DA approach connects an entire supply chain—from part manufacturing at an elementary level to an OEM’s final assembly line level. Addressing the whole process of aircraft design and manufacturing is necessary to develop further collaboration models between OEMs and the supply chain, including addressing the most pressing technology challenges. Since all parts aggregate at the OEM level, the OEM—as an integrator of all these single parts—needs special end-to-end methodologies to drastically decrease cost and lead time. This holistic approach can be considered in part design as well (in the design-for-automation and design-for-assembly philosophy). This allows for quicker assembly at the OEM level, such as “part-to-part” or “hole-to-hole” approaches, versus traditional, classical assembly methods like manual measurement or measurement-assisted assembly. In addition, it can increase flexibility regarding rate changes in production (such as those due to pandemic- or climate-related environmental challenges). The standardization and harmonization of these areas would help all industries and designers to have a deterministic approach with an end-to-end concept. Simulations can easily compare possible production and assembly steps with different impacts on local and global tolerances. Global measurement feedback needs high-accuracy turnkey solutions, which are very costly and inflexible. The goal of standardization would be to use Industry 4.0 feedback and features, as well as to define several building blocks of the DA approach as a one-way assembly (also known as one-up assembly, or “OUA”), false one-way assembly, “Jig-as-Master,” etc., up to the hole-to-hole assembly approach. The evolution of these assembly principles and the link to simulation approaches are undefined and unsolved domains; they are discussed in this report. They must be discussed in greater depth with aims of (first) clarifying the scope of the industry-wide alignment needs and (second) prioritizing the issues requiring standardization. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the challenges they identify or close any topic to further scrutiny.

Abstract:
Aus der Einleitung: Given two ontologies/terminologies collections of terms and their 'meanings' as used in some universe of discourse (UofD), our general task is to integrate them into a single ontology, which captures the meanings of the original terms and their inter-relationships. This problem is motivated by several application scenarios: • First, such ontologies have been and are being developed independently by multiple groups for knowledge-based and other applications. Among others, medicine is an area in which such ontologies already abound [RZStGC, CCHJ94, SCC97]. • Second, a traditional step in database design has been so-called 'view integration': taking the descriptions of the database needs of different parts of an organization (called 'external views'), and coming up with a unified central schema (called the 'logical schema') for the database [BLN86]. Although the database views might be expressed in some low-level formalism, such as the relational data model, one can express the semantics (meta-data) in a more expressive notation, which can be thought of as an ontology. Then the integration of the ontologies can guide the integration of the views. • Finally, databases and semistructured data on the internet provide many examples where there are multiple, existing heterogeneous information sources, for which uniform access is desired. To achieve this goal, it is necessary to relate the contents of the various information sources. The approach of choice has been the development of a single, integrated ontology, starting from separate ontologies capturing the semantics of the heterogeneous sources[Kas97, CDGL+98]. Of course, we could just take the union of the two ontologies, and return the result as the integration. However, except for the case when the ontologies had absolutely nothing to do with each other, this seems inappropriate. Therefore part of our task will to be explore what it means to 'integrate' two ontologies. To help in this, we will in fact assume here that the ontologies are describing exactly the same aspects of the universe of discourse (UofD), leaving for a separate paper the issue of dealing with partially overlapping ontologies.
