Abstract:

The Coulomb propulsion system has no exhaust plume impingement problem with neighboring spacecraft and does not contaminate their sensors because it requires essentially no propellant. It is suitable to close formation control on the order of dozens of meters. The Coulomb forces are internal forces of the formation and they influence all charged spacecraft at the same time. Highly nonlinear and strongly coupled equations of motion of Coulomb formation makes creating a Coulomb control method a challenging task. Instead of positioning all spacecraft, this study investigates having a sensor craft be sequentially controlled using dedicated drone craft. At least three drone craft are required to control a general sensor craft position in the inertial space. However, the singularity of a drone plane occurs when a sensor craft moves across the drone plane. A bang-bang control method with a singularity check can avoid this problem but may lose formation control as the relative distances grow bounded. A bang-coast-bang control method utilizing a reference trajectory profile and drone rest control is introduced to increase the control effectiveness. The spacecraft are assumed to be floating freely in inertial space, an approximation of environments found while underway to other solar system bodies. Numerical simulation results show the feasibility of sensor craft control using Coulomb forces.

Abstract:

This thesis investigates the design and evaluation of a control system, that is able to adapt quickly to changes in environment and steering characteristics. This type of controller is particularly suited for applications with wide-ranging working conditions such as those experienced by small motorised craft. A small motorised craft is assumed to be highly agile and prone to disturbances, being thrown off-course very easily when travelling at high speed 'but rather heavy and sluggish at low speeds. Unlike large vessels, the steering characteristics of the craft will change tremendously with a change in forward speed. Any new design of autopilot needs to be to compensate for these changes in dynamic characteristics to maintain near optimal levels of performance. This study identities the problems that need to be overcome and the variables involved. A self-organising fuzzy logic controller is developed and tested in simulation. This type of controller learns on-line but has certain performance limitations. The major original contribution of this research investigation is the development of an improved self-adaptive and predictive control concept, the Predictive Self-organising Fuzzy Logic Controller (PSoFLC). The novel feature of the control algorithm is that is uses a neural network as a predictive simulator of the boat's future response and this network is then incorporated into the control loop to improve the course changing, as well as course keeping capabilities of the autopilot investigated. The autopilot is tested in simulation to validate the working principle of the concept and to demonstrate the self-tuning of the control parameters. Further work is required to establish the suitability of the proposed novel concept to other control.

Abstract:

Large marine vessels carry their loads all over the world. It can be a container ship carrying over 10 000 containers filled with foods, textiles and electronics or a bulk freighter carrying 400 000 tons of coal. Vessels usually have a ballast system that pumps water into ballast tanks to stabilize the vessel. The ballast system can be used to change the vessel’s trim and list angles. Trim and list are the ship equivalents of pitch and roll. By changing the trim angle the water resistance can be reduced and thus also the fuel consumption. Since the vessel is consuming a couple of hundred tons of fuel per day, a small reduction in fuel consumption can save a considerable amount of money, and it is good for the environment. In this thesis, the ship’s power consumption has been estimated using an artificial neural network, which is a mathematical model based on data. The name refers to certain structural similarities with the neural synapse system in animals. The idea with neural networks has been to create brain-like systems. For applications such as learning to interpret sensor data, artificial neural networks are an effective learning method. The goal is to estimate the ship power using a artificial neural network and then use it to calculate the trim angle, to be able to save fuel. The data used in the artificial neural network come from sensor systems mounted on a container ship sailing between Europe and Asia. The sensor data have been thoroughly preprocessed and this includes for example removing the parts when the ship is docked in harbour, data patching and synchronisation and outlier detection based on a Kalman filter. A physical model of a marine craft including wind, wave, hydrodynamic and hydrostatic effects, has also been introduced to help analyse the performance and behaviour of the artificial neural network. The artificial neural network developed in this thesis could successfully estimate the power consumption of the ship. Based on the developed networks it can be seen that the fuel consumption is reduced by trimming the ship by bow, i.e., the ship is angled so the bow is closer to the water line than the stern. The method introduced here could also be applied on other marine vessels, such as bulk freighters or tank ships.

Abstract:

Industrialization of construction is a business strategy to significantly improve competitiveness. However, the organization structure of the construction firms needs to support the new production system. The knowledge on why and how this business development can be accomplished is scarce, both within academia and in business practice. This research seeks to fill this knowledge gap. The purpose of organization structure and the production system have is to coordinate the firm’s processes and control the work performing resources. Information is one of the most fundamental dimensions for steering and controlling the work. The different information types are determined by the firm’s product customization strategy and the production system flexibility. Further, diverse information types are managed in different extent by the organizational steering mechanisms. Consequently, firms with dissimilar customization strategy or production flexibility should organizationally be designed differently in order to be efficient. The developed model identifies four generic production topologies: “engineer-to-order” (ETO), “manufacture-to-order” (MTO), “assembly-to-order” (ATO), and “make-standard-products” (MSP). The differences between the topologies can be related to the location of the “customer-order-decoupling-point” (CODP) in the product realization process; and to what extent the upstream and downstream processes continuously use stored information or process information to accomplish the work of each product order. The model predicts which organization structure mechanisms that should be used for which processes for each production topology. It is the specific configuration of the mechanisms that gives each production topology their organizational capability. The model has been validated by case studies in four organizations, each representing one of the four generic production topologies. Three cases considered housing and one studied truck manufacturing. It has been shown that the conventional housing firms have an ETO-production topology, while industrialized housing firms belonging to one of the others, i.e. MTO, ATO or MSP. The reason is that ETO-firms rely on crafts-based production to manage the work, while the other topologies base their steering mechanisms on industrial principles. These two types of production are fundamentally different, which also explain the need for different organization structures. The research complements previous knowledge and significantly increases the ability to predict, analyze and explain an organization’s design and behavior. The model can be used in practice to guide business development work and performance improvement programs.

Abstract:

Approved for public release; distribution is unlimited.
U.S. military and civilian vessels are critically vulnerable to asymmetric threats in littoral environments. Common asymmetric weapons such as Anti-Ship Cruise Missiles (ASCM), Low Slow Flying (LSF) aircraft and Fast Attack Craft (FAC) / Fast Inshore Attack Craft (FIAC) threaten U.S. strategic goals and can produce unacceptable losses of men and material. The SEA-18B team presents an operational concept for a family of Unmanned Surface Vessels USV) capable of defending ships from asymmetric swarm attacks. This USV, the Tailorable Remote Unmanned Combat Craft (TRUCC), can operate in concert with the next generation of capital surface vessels to combat this critical threat with maximum efficiency. Critical performance criteria of the TRUCC family were determined through agent-based simulation of a Straits of Hormuz Design Reference Mission. Additional models addressed ship synthesis and operational availability. A Technology and Capability Roadmap outlines areas of interest for investment and development of the next-generation USV. Interim technology and capability milestones in the Roadmap facilitate incremental USV operational capabilities for missions such as logistics, decoy operations and Mine Warfare. The TRUCC operational concept fills a critical vulnerability gap. Its employment will reduce combat risk to our most valuable maritime assets: our ships and our Sailors.

Abstract:

This thesis contains new results on the problem of coordinating a group of vehicles. The main motivation driving this work is the development of control laws that steer individual members of a formation, such that desired group behavior emerges. Special attention is paid to analysis of coordination issues, in particular formation control of marine craft where robustness to unknown environmental forces is important. Coordinated control applications for marine craft include: underway replenishment, maintaining a formation for increased safety during travel and instrument resolution, and cooperative transportation. A review of formation control structures is given, together with a discussion of special issues that arise in coordination of independent vehicles.

The main contributions of this thesis may be grouped into two categories:

• Path-following designs for controlling a group of vehicles

• Multi-body motivated formation modeling and control

A previously developed path following design is used to control a group of vehicles by synchronizing the individual path parameters. The path following design is advantageous since the path parameter, i.e., that parameter which determines position along a path, is scalar; hence coordination is achieved with a little amount of real-time communication. The path following design is also extended to the output-feedback case for systems where only parts of the state vector are known. The path following scheme is exploited further in a passivity-based design for coordination where the structural properties render an extended selection of functions for synchronization available. Performance and robustness properties in different operational conditions can be enhanced with a careful selection of these functions. Two designs are presented; a cascaded interconnection where a consensus system provides synchronized path parameters as input to the individual path following systems renders time-varying formations possible and increases robustness to communication problems; a feedback interconnection which is more robust to vehicle failures. Both designs are extended to sampled-data designs where plant and controller dynamics are updated in continuous-time and path parameters are exchanged over a communication network where transmission occurs at discrete intervals. Bias estimation is included to provide integral action against slowlyvarying environmental forces and model uncertainties.

A scheme for formation modeling and control, inspired by analytical mechanics of multi-body systems and Lagrangian multipliers, is proposed. In this approach to formation control, various formation behaviors are determined by imposing constraint functions on group members. Several examples illustrate these formation behaviors. The stabilization scheme presented is made more robust with respect to unknown time-varying disturbances. In addition, the scheme is extended towards adaptive estimation of unknown plant and parameters. Furthermore, it can be applied with no major modifications to the case of position control for a single vehicle.

The formation control scheme is such that it may be used in combination with a set of position control laws for a single vessel, thus enabling the designer to choose from a large class of control laws available in the literature. The input-to-state stability (ISS) framework is utilised to investigate robustness to environmental and communication disturbances. A loop-transform, together with the ISS framework, yields an upper bound on the inter-vessel time delay below which formation stability is maintained.

CIVINS
Early stage ship design and assessment continues to be a challenge for naval architects and ocean engineers. The complex and multifaceted interactions between the different components of the ship and the broad spectrum of disciplines required in ship design make it difficult to fully realize the effects of any one change on the entire system. The initial design of smaller patrol craft is especially difficult due to the lack of design tools able to deal with ships of small size operating in the semi-planing region. This paper puts forth a method for narrowing the design space for patrol craft design. Using a systems approach, a Patrol Craft Assessment Tool (PCAT) was created and tested to aide designers in the initial design and assessment of patrol craft of 200 ft. PCAT is an open source MATLAB code that incorporates resistance, engine selection, structures, and mission profiles into one design program to aide a designer in optimizing a patrol craft.

Abstract:

This thesis presents a philosophical, theoretical, practical and methodological discussion of the relationship between humans and technology in relation to technically assisted movement. The themes are investigated in five articles. In particular, the philosophical foundation of different perspectives on the relationship between humans and technology are discussed with a special emphasis on movement. The thesis then proceeds to present a case study of high-speed crafts in military service. The empirical data is gathered through the use of participatory observation. The operation of this type of ship is characterised by hazardous and uncertain conditions. High speed craft operation is considered very demanding for the navigators in terms of maintaining safety and efficiency. The observation accumulated over 120 hours of video recorded material of the crew during ship operation. This serves as a basis for a discussion and explication of specific theoretical frameworks for conceptual modelling of ship manoeuvring, as well as design of prototypes of new technological artefacts intended for the operation of the ship class. Further, this thesis addresses the issue of methodological challenges when studying elaborate human-technology systems by discussing the use of video in field observation.

Abstract:

NASA missions require innovative power electronics system and component solutions with long life capability, high radiation tolerance, low mass and volume, and high reliability in space environments. Presently vertical double-diffused MOSFETs (VDMOS) are the most widely used power switching device for space power systems. It is proposed that a new lateral double-diffused MOSFET (LDMOS) designed at UCF can offer improvements in total dose and single event radiation hardness, switching performance, development and manufacturing costs, and total mass of power electronics systems. Availability of a hardened fast-switching power MOSFET will allow space-borne power electronics to approach the current level of terrestrial technology, thereby facilitating the use of more modern digital electronic systems in space. It is believed that the use of a p+/p-epi starting material for the LDMOS will offer better hardness against single-event burnout (SEB) and single-event gate rupture (SEGR) when compared to vertical devices fabricated on an n+/n-epi material. By placing a source contact on the bottom-side of the p+ substrate, much of the hole current generated by a heavy ion strike will flow away from the dielectric gate, thereby reducing electrical stress on the gate and decreasing the likelihood of SEGR. Similarly, the device is hardened against SEB by the redirection of hole current away from the base of the device's parasitic bipolar transistor. Total dose hardness is achieved by the use of a standard complementary metal-oxide semiconductor (CMOS) process that has shown proven hardness against total dose radiation effects.

This paper describes my work with a historical craft and my attempt to find new ways to look at it, work with it and present it. I use the embroidery technique Hardangersaum which is all white, and where selected threads of the woven fabric grid are removed while others are wrapped and embellished. The artistic research leans heavily on the traditional craft but tries to isolate it from its historical baggage. I turn my focus to the grid of the fabric and I present some viewpoints from Rosalind Krauss and Hannah B. Higgins. I describe questions of scale and presentation that have emerged and show how digital animation has played a major role in the development and the communication of the embroidery work.

Full text

Abstract:

Modern web services can see well over a billion requests per day. Data and services at such scale require advanced software and large amounts of computational resources to process requests in reasonable time. Advancements in cloud computing now allow us to acquire additional resources faster than in traditional capacity planning scenarios. Companies can scale systems up and down as required, allowing them to meet the demand of their customers without having to purchase their own expensive hardware. Unfortunately, these, now routine, scaling operations remain a primarily manual task. To solve this problem, we present CRAFTS (Cloud Resource Anticipation For Timing Scaling), a system for automatically identifying application throughput and predictive scaling of cloud computing resources based on historical data. We also present ARTS (Automated Request Trace Simulator), a request based workload generation tool for constructing diverse and realistic request patterns for modern web applications. ARTS allows us to evaluate CRAFTS' algorithms on a wide range of scenarios. In this thesis, we outline the design and implementation of both ARTS and CRAFTS and evaluate the effectiveness of various prediction algorithms applied to real-world request data and artificial workloads generated by ARTS.

Full text

Abstract:

Cette recherche s’inscrit dans le champ de la sécurité des activités artisanales. Basée sur l’étude de la profession de guide de montagne, système artisanal par excellence, elle vise à mieux comprendre la manière dont la sécurité peut se construire dans ce type de systèmes encore peu analysé. Notre travail consiste d’abord à analyser la manière dont les guides, travailleurs indépendants, régulent en permanence leur prise de risque face aux dangers naturels, tout en tenant les autres dimensions de l’activité (économique, servicielle, sociale, etc.). Puis, il vise à proposer une prévention qui favorise cette régulation naturelle.La thèse soutenue est la suivante : la construction de la sécurité dans un système artisanal passe à la fois par le développement du « savoir agir » et du « pouvoir agir » des professionnels. En se plaçant dans une approche adaptative et systémique de la sécurité, il s’agit de miser sur la responsabilité, l’autonomie et l’autonomisation des professionnels, qui restent les seuls compétents pour décider en situation. L’action ergonomique doit alors favoriser la contribution de tous les niveaux du système (macro, meso, micro) à la construction d’un environnement capacitant permettant aux acteurs et aux collectifs « d’agir en sécurité ».Quatre études empiriques ont été conduites pour défendre cette thèse. Celles-ci sont basées sur des données récoltées lors d’entretiens semi-directifs et d’observations participantes filmées de courses avec des guides de montagne. Chacune de ces études est construite à partir d’une méthode particulière d’analyse de ces données. La première étude porte sur l’analyse de la perception des risques des guides de montagne. Elle permet de caractériser les risques auxquels s’exposent les guides et leurs clients. Elle met notamment en évidence que la course implique la gestion de risques endogènes, qui dépendent de l’activité de la cordée, et de risques exogènes, qui renvoient à la dynamique intrinsèque de l’environnement de travail. La deuxième étude s’intéresse à l’activité de préparation de la course. Elle montre que cette préparation peut être abordée comme une activité de conception visant à se construire un espace de situations acceptables intégrant les risques endogènes et exogènes. La troisième étude porte sur la réalisation de la course en montagne. Basée sur le cadre théorique de la gestion de situations dynamiques, elle s’intéresse à la manière dont les guides se construisent une conscience de la situation, élaborent des plans dans l’action et agissent pour se maintenir dans un espace de situations acceptables. Enfin, la quatrième étude se focalise sur les « arbitrages risqués » observables dans l’activité. Elle vise à mieux comprendre les mécanismes qui peuvent pousser les guides à prendre des risques, à toutes les étapes de la course, mais aussi à l’échelle de la saison ou de la carrière. Cette dernière étude montre que les processus d’arbitrage visent à tenir de façon permanente différents compromis entre toutes les ressources et contraintes des situations. Elle permet de comprendre qu’un des principaux enjeux de sécurité concerne le traitement de ces arbitrages risqués pour éviter un débordement de la prise de risque dans le temps.Nos résultats peuvent donc être résumés de la façon suivante : « Les guides de montagne doivent gérer des risques endogènes et exogènes, afin de se placer dans un espace de situations acceptables et de s’y maintenir de façon dynamique en évitant des débordements dans la prise de risque ». Ces résultats permettent de proposer une explication des accidents à partir de la prise de risque. Ils permettent aussi d’envisager de nouveaux moyens de prévention basés non plus sur la maitrise de l’enchainement des évènements de la course mais sur la gestion des mécanismes pouvant entrainer une accumulation des prises de risques
This research adresses safety issues in craft activities. Drawing on a study of the mountain guide profession, an archetypal craft system, it aims to provide a better understanding of the way in which safety can be constructed in this type of system, which is still relatively unexplored. Our work focuses on analyzing how self-employed guides constantly regulate their risk-taking in the face of natural hazards, while taking into account the other dimensions of their activity (economic, service, social, etc.). The aim is then to propose a prevention strategy that encourages this natural regulation. The thesis assumes that the construction of safety in a craft system calls for the development of both the ‘know-how‘ and the ‘capability' of professionals. By adopting an adaptative, systemic approach to safety, we rely on the responsibility, autonomy and empowerment of professionals, who remain the only ones competent to take decisions in a work situation. Ergonomic action must therefore promote the contribution of all levels of the system (macro, meso, micro) to the construction of an enabling environment that allows actors and collectives to “act safely”.Four empirical studies have been carried out to support this thesis. These are based on data gathered from semi-structured interviews and filmed participant observations of alpine tours with mountain guides. Each of these studies is based on a specific method of data analysis. The first study analyzes the risk perception of mountain guides. It characterizes the risks to which guides and their clients are exposed. It reveals that an alpine tour involves managing both endogenous risks, which depend on the activity of the climbing team, and exogenous risks, which refer to the intrinsic dynamics of the work environment. The second study focuses on the preparation of the alpine tour. It shows that this preparation can be approached as a design activity aimed at constructing a space of acceptable situations integrating endogenous and exogenous risks. The third study focuses on the realization of the alpine tour. Based on the theoretical framework of the management of dynamic situations, it examines how guides construct situation awareness, develop plans in action and act to maintain themselves in a space of acceptable situations. Finally, the fourth study focuses on the “risky trade-offs” that can be observed in the work. It aims better understand the mechanisms that can lead guides to take risks, at all stages of the alpine tour, but also on a season-long or career-long perspective. This latest study shows that trade-off processes aim to permanently hold different compromises between all the resources and constraints of situations. It shows that one of the main safety issues concerns the management of these risky trade-offs, to prevent risk-taking from getting out of control over time.Our results can therefore be summarized as follows: “Mountain guides have to manage endogenous and exogenous risks, in order to place themselves in a space of acceptable situations and maintain themselves there dynamically, while avoiding risk-taking excesses”. These results enable us to propose an explanation for accidents based on risk-taking. They also suggest new ways of preventing accidents, based not on controlling the sequence of events in the alpine tour, but on managing the mechanisms that can lead to an accumulation of risk-taking

Abstract:

Regionally focused plant breeding has the potential to increase the productivity and profitability of dry beans and barley in western Washington, strengthening the local food system. Achieving this will require an interdisciplinary approach rooted in an understanding of social context, unique end-use potential, contemporary genetic techniques, and crop production methods, combined with the art and science of classical field-based breeding. Approaches to plant breeding for local food systems are reviewed emphasizing the potential of engaging diverse stakeholders in the selection process. Barriers to local dry bean production include access to scale appropriate equipment and drying the crop, however dry beans are being successfully grown in the region. Twenty-four varieties of dry beans, which have been cultivated in western Washington for 20 to 130 years, were collected. Utilization of these local heirlooms will require respectful engagement with the seed savers responsible for their maintenance and selection. Information on dry bean variety selection, production methods, pest management, harvesting and drying is presented. Growers producing malting barley may receive a premium for their crop, but require traits unique to that market. Locally adapted varieties were identified with stable yield and grain quality, as well as resistance to leaf rust (Puccinia hordei ), powdery mildew (Blumeria graminis f. sp. hordei) and pre-harvest sprouting. Custom malting of these varieties has the potential to contribute to the emerging craft malt industry. Continued development of regionally adapted varieties is supported through a genome wide association study of a foundational panel of two-row facultative malting barley. Significant markers associated with heading date genes were identified as well as resistance to stripe rust (P. striformis f. sp. hordei), leaf rust (P. hordei), and scald ( Rhyncosporium commune). The concepts and methods presented here can be transferred to other regions and crops where producers and researchers wish to leverage variety selection and breeding to achieve a resilient and productive food system with its own distinctive place-based character.

Abstract:

This thesis examines the development of a capital goods industry in Mendoza Argentina through an analysis of linkages and industrial governance systems. Linkages are material, informational, and financial flows among firms. Industrial governance systems are the social practices that cement linkages. Hence, linkages are understood as socially embedded and not as market transactions governed solely by price considerations. The study has two major arguments. First, it claims that contrary to conventional industrial location theory firms do not locate in view of the previous existence of certain favorable factors, but rather construct these factors as they grow. This argument is operationalized by asking how firms generate in time their own linkages. Examples taken from the 1895-1990 period include labor and subcontractors, clientele, services, and the emergence of economic groups. Second, this study argues that the capital-goods industry in Mendoza is undergoing a Substantial (and unprecedented) transition in the way production is organized. The transition is part of the larger shift taking place at both the national and global scales. The analysis focuses on the historical pattern of linkages and governance systems in the industry, and contrasts that pattern with that of the recent decade. Implicit in the previous two arguments are two territorial dimensions. First, the development of “industry produces regions" (Storper and Walker 1989). Second, at the intra-city level this means that the evolution of the industry (and specifically its linkage structure and governance systems) has a direct bearing on the direction and nature of the city’s growth. These two arguments are illustrated through empirical work in Mendoza, a city of close to a million people in western Argentina. Over 100 interviews gathered over ten months reveal the origins, evolution, and current form of linkages in the capital-goods industry. These interviews are complemented by data from a variety of sources. The main conclusions of the study are three. First, the study illustrates the richness and depth that emerges from a project based on substantial fieldwork. Second, it shows the advantages of conceiving industrialization not as the location of plants in response to favorable conditions, but as a process initiated by the firms themselves. Third, the dissertation shows that the capital-goods industry of Mendoza iS in a transitional phase towards new ways of organizing production. The transition is expressed in new linkage structures, new governance systems, and the emergence of new types of firms and institutional arrangements.

Abstract:

Non-timber forest products (NTFPs) are important in rural southwest Virginia as a source of household sustenance and supplemental income. The trade in NTFPs from this region is centuries old and now helps supply growing worldwide demands. Although marketing is a vital part of optimizing the value of these products, it has been ignored in rural natural resource development. This research analyzes marketing systems for selected NTFPs in southwest Virginia by describing marketing chains, interpreting data on important marketing elements, and comparing results within and between different groups of NTFPs. Product categories selected for emphasis are crafts (grapevine wreaths, baskets, furniture, and birdhouses), medicinal and herbal products, specialty wood products (musical instruments), and edible forest products. This qualitative, exploratory study utilizes direct interviews with fifty market players at various levels in marketing chains. Results provide information on NTFP products, value addition, market outlets, pricing, promotion, distribution, and marketing chains. Hundreds of people are involved with the NTFP trade in southwest Virginia and marketing can help ameliorate negative effects of job scarcity. The greatest opportunity for local level marketing exists for market players of crafts and specialty wood products. Medicinal and herbal products are the only category which very little local value addition takes place within the region and as a result, market players have minimal control over marketing. Edible forest products are not marketed but are collected only for consumption in the household. Several opportunities for marketing include improving market access for crafts and specialty wood products, increasing production through cultivation for medicinal and herbal products, and developing capacity for edible product cultivation.

One of the global security challenges the United States faces is disaster coupled with political instability. The U.S. Military‘s ability to rapidly respond to disasters enhances regional and global security and stability. Foreign Humanitarian Assistance and Disaster Relief (FHA/DR), increasingly a mission that relies on a significant military component, focuses on the provision of goods and services such as health care, supplies necessary for survival, and infrastructure repair, with the goal of reducing the immediate human suffering. The disaster in this project‘s scenario is catastrophic flooding that occurs in one of Africa‘s most populated and wealthiest countries that threatens the stability and development of West Africa. This project, employing a systems engineering methodology, focuses on the 60 days after the disaster and the requirements to provide this assistance in the form of goods and services. Many system-of-systems architectures were developed to investigate the effectiveness of utilizing a Seabase for the primary delivery of aid. Two simulation tools, SimKit, and STELLA, were used to model and examine these architectures with the former addressing the delivery and throughput concerns while the latter focused on the satisfaction of the population and the limitation of criminal activity. Based on the results of modeling, the team provided recommendations relative to the most effective architectures in influencing the population of this coastal area as well as accomplishing the FHA/DR mission.

Abstract:

Detta arbete ämnar undersöka förändringar i olycksstatistiken mellan 1990 till 2000 och 2001 till 2014 vid sjösättning och återställning av snabbgående beredskapsbåtar. Genom att göra en litteraturstudie, där huvudsakliga källan innebar sekundärdata i form av olycksrapporter från brittiska haverikommissionen kunde en sammanställning av antal olyckor, olycksorsak och personskador mellan 2001 och 2014 utföras. Detta resultat jämfördes sedan mot en tidigare studie som undersökte samma ämne mellan 1990 och 2000. Resultatet i jämförelseanalysen visade en minskning av antalet olyckor som inträffar vid sjösättning och återställning av snabbgående beredskapsbåtar. Utrustning som används vid olyckstillfällena tyds har blivit säkrare sedan förra studien utfördes då utrustningen tidigare var den största orsaken till olyckor. Resultatet i denna studie visar istället att det är besättningens agerande vid sjösättning och återställning som leder tills flest olyckstillbud.
The purpose of this study was to investigate the causes behind accidents at the launching and recovery phase of fast rescue boats on RO/RO passenger ships between 2001 and 2014. The purpose was also to examine what the consequences may be for the crew in this type of accident. When the objective of this study was achieved, it was decided that a depression on the topic would be performed by making a statistical comparison to investigate how this types of accidents has changed since 1990-2000. The study was done as a literature study where secondary non-experimental data was used as the material for the compilation of the results. The material obtained in the form of accident summaries from the British Marine Accident Investigation Branch. This source was chosen to be used because the previous study was based on the same commission’s statistics of accident in the result United Kingdom FRB Working Group presented in 2001. After the result in this study had been compiled and was able to present how many accidents that have occurred within the period covered, and what had caused the accidents was decided a comparison study with previous research was conducted. Comparative results of the analysis showed that the total number of accidents has decreased since the last study was conducted. From the results it can be inferred that the main reason of the accidents has decreased, probably is because the equipment used in this kind of operation has become safer.

Abstract:

This thesis aims to study the design possibilities for supporting explorative form-finding in 3D modeling applications. For today’s many design professions, 3D forms are achieved partly in engagement with digital environments. Use of software has far exceeded final idea execution, extending to the early phases of design work in which the outcome is not predetermined. This insight led designers of interactive systems support sketching and ideating activities by reducing the risk of experimentation and cognitive effort demanded from user. Yet, there has been less emphasis on traditional design and craft practice that acknowledges engagement with materials and effort spent on work as an integral part of creative process.The notion of exploration in the scope of this thesis attempts to incorporate such aspects. Relevant literature about workshop practice in design and craft has been reviewed, as well as examples of CAD technologies that aid designers. In this light, HCI perspectives on the design of creativity support tools and games have been discussed. The thesis work aimed to concretize this background by building a design strategy and an interactive artifact. A 3D form-finding application concept using objects in modeling space to indirectly manipulate geometry, “kfields”, has been developed and evaluated with users at various stages. The thesis concludes by reflecting on the findings of different design stages and proposing further directions for design.

Full text

Abstract:

This study assesses the organization and intensity of hide processing from sequential occupations at the Late Fort Ancient (A.D. 1400-1680) Hardin Site located in the central Ohio Valley. Historical and archaeological sources were drawn on to develop expectations for production intensification: 1) an increase in production tool quantity, 2) an increase in production debris quantity, and 3) an increase in tool utilization intensity. Many Native groups situated on the periphery of early European colonies intensified hide production to meet demand generated by an emerging global trade in hides. As this economic activity intensified in the 16th and 17th centuries it incorporated and ever greater network of native communities. By documenting production intensification at the Hardin Site, this study evaluates the degree to which global markets incorporated regions beyond the colonial periphery before A.D. 1680. This study also examines the social dimensions of economic activity by asking who processed hides, who may have benefited from the products of this labor, and whether or not either of these were influenced by participation in the tumultuous interaction sphere of the eastern North American Contact Period.

Abstract:

The relationship between surface, perception, and structure has occupied my graduate studies. Locating, transforming, and transcending the surface requires play with perceptive abilities not only of vision, but of touch, hearing, and the other senses as well. How do the interactions of sense with the qualities of a surface determine our perception of the world? What role does the extension of the senses play in one's ability to perceive surface and structure? Using sense information gleaned from surfaces, the tectonics of our world are made visible. Might this relationship be played backwards as well? Composed structures produce surfaces upon which limina can be sensed.This written accompaniment to the thesis works is intended to continue the exploration of the surface/ sense/ structure relationship. With the visual work as a basis, each section consists of two parts. This structure is a tool for producing sense information for the viewer concerning the visual work.The first part serves as a bridge between the particular visual work and the second part. Consisting of a page or so of text, the first part of each section is also intended to set a tone or position the reader for the second part. The second part is more formal and speaks about the ideas behind the produced object, and for the most part could be applied to any works in this thesis. My desire is that the adjacency of the pieces in each section will create a friction of sorts an awareness of the surface between the two writings, and perhaps, between the writing and the objects.

Abstract:

Diese Dissertation umfasst drei Aufsätze, von denen sich die ersten beiden mit dem Phänomen der beruflichen Mobilität von Arbeitnehmern im westdeutschen Arbeitsmarkt befassen. Der erste Aufsatz untersucht für Absolventen einer dualen Berufsausbildung die kausalen Lohneffekte von Mobilität über Firmen und Berufe hinweg. Die Instrumentenvariablenschätzungen, welche exogene Variation in regionalen Arbeitsmarktcharakteristika ausnutzen, zeigen, dass Berufswechsel innerhalb des Ausbildungsbetriebs einen Karrierefortschritt darstellen. Bei Jobwechseln dominiert der Verlust von firmenspezifischem Humankapital. Allerdings nimmt der Lohnverlust nicht weiter zu, wenn zusätzlich zur Firma auch der Beruf gewechselt wird. Angesichts dieser Ergebnisse dokumentiert der zweite Aufsatz Muster von beruflicher Mobilität in Westdeutschland über den Zeitraum 1982--2008 innerhalb von und zwischen Firmen. Die Häufigkeit von beruflicher Mobilität hat seit 1982 zwischen Firmen signifikant zugenommen und innerhalb von Firmen signifikant abgenommen. Die Analyse betrachtet zudem mögliche Erklärungsansätze für diese Entwicklungen, wie zum Beispiel den demografischen Wandel oder den Zusammenhang zwischen beruflicher Mobilität und Arbeitslosigkeit. Der dritte Aufsatz untersucht den Zusammenhang zwischen Produktmarktderegulierung und Arbeitsmarktergebnissen. Die Reform der deutschen Handwerksordnung von 2003 wird als natürliches Experiment genutzt, um mögliche Einflüsse der Abschaffung von Markteintrittsbarrieren auf selbstständige und abhängige Beschäftigung zu untersuchen. Da Zweifel an der Gültigkeit der identifizierenden Annahmen aufkommen, können die Schätzergebnisse nicht kausal interpretiert werden. Dennoch legen die Ergebnisse zumindest in Teilen nahe, dass der in der Literatur bereits dokumentierte positive Effekt auf selbstständige Beschäftigung plausibel ist, wohingegen die Reform vermutlich keinen Anstieg der abhängigen Beschäftigung in den deregulierten Berufen zur Folge hatte.
This thesis comprises three essays, out of which the first two study the phenomenon of worker mobility across occupations in the West German labor market. The first essay studies the causal wage effects of mobility across firms and occupations among graduates from apprenticeship training. Exploiting variation in regional labor market characteristics the instrumental variables estimations indicate that occupation switches within the training firm involve a career progression. For job switches the loss of firm-specific human capital seems to dominate. However, the wage loss does not grow when an occupation switch occurs simultaneously. In light of these results, the second essay in this thesis studies patterns of occupational mobility in West Germany over the period 1982--2008 separately within and across firms. Most importantly, occupational mobility rates across firms have significantly increased since the early 1980s, while within-firm occupational mobility rates have significantly decreased. The essay also assesses potential explanations for these developments, such as demographic change or the relationship between occupational mobility and unemployment. The third essay in this thesis studies the relationship between product market deregulation and labor market outcomes. It exploits the 2003 reform of the German Crafts Code as a natural experiment to study how the abolishment of barriers to firm entry may affect self-employment and dependent employment. Since there are doubts regarding the validity of the identifying assumptions, the results cannot be interpreted causally. Nevertheless, the analysis at least partially corroborates the evidence for a positive reform effect on self-employment documented elsewhere in the literature, while the reform seems not to have had a positive effect on dependent employment in the deregulated crafts occupations.

Abstract:

For my MFA, I have decided to explore data visualization not as an automated technology but as a craft—a systematic and precise practice done entirely by hand. Though the craft-based approach is not appropriate for all types of data creation and visualization, as an investigatory tool it grants a level of access and intimacy lacking in computerized analyses. I discuss the limitations and benefits of this type of approach, as well as provide an overview of key influences and precedents. I have also included select projects developed over the course of my studies that highlight my use of data visualization for a range of subjects and intents, including reading piano sheet music more easily and investigating a photographer’s compositional process. The report concludes by projecting how this craft-based approach for data visualization may be integrated with an automated method.

The goal of this thesis is to design an easily installed and reliable system of ducted propeller for the boat speed operated between 25 to 30 knots. The open water test of the system is carried out in NTOU medium-sized cavitation tunnel, to investigate the influence of the nozzle geometry and the pre-swirl stator on the propeller efficiency and cavitation. From the experimental results, it is shown that the cavitation on the propeller blade and propeller efficiency can be improved by decelerating nozzle. The geometry at leading edge of the nozzle plays an important role for the cavitation control of the nozzle. In order to avoid the strut cavitation, it can be designed to be multiple blades to reduce its thickness. By using the pre-swirl stator to replace the strut, the propeller efficiency can be increased significantly.

With the development of information technology, digital times have come already. In order to keep up with the international development trend, Taiwan government policies push for the technology industry as the main direction. With the deep historical and cultural background, Taiwan is rich of traditional crafts. Nevertheless, in the vigorous development of technology industry that makes traditional crafts face the impact of losing talent, high producing cost and other industrial recession as well, and industrial transformation is inevitable future. With the popularity of the development of technology, information and digitalization have become the essential content in each person's life; and the literature indicates that the greatest impact is the digital community. The initial explorations of the study found that users in the digital community will constantly exchange messages and share resources through the platforms; the users and information are the keys to sustaining the development of the social media communities. Through the different forms of information sharing and resources of feedback, the social community platforms could be self-sustainable operation. According to the concept of ecosystems, the biotic community (user) and the environment (platform) forming a whole; and each other conveys messages (information) and interdependent relationship to form a self-organized and adjusted complex to achieve the so-called permanent sustainable ecosystem. This study proposed the concept of "digital ecosystem" by focusing on leading in the mechanism and conditions of the digital community with the characteristics of the ecosystem self-circulation. Then according to the analysis of the composition of the ecosystem that is being as the base to analyze the ecological chain of the traditional craft. In the end, through the integration of digital ecosystem conditions and the development of traditional craft industry nowadays to propose the development model of the traditional craft industry in the digital ecosystem. The research methods of this study are questionnaire survey and in-depth interview. Based on the result of literature review, the platforms of social media community are classified as the prototype of the digital ecosystem; and then using field research to induct the ten mechanisms of the six platforms. The in-depth interviews are based on the literature review to explore the characteristics and composition of industrial ecosystems and commercial ecosystems; then according to the characteristics and the members of composition including enterprise, customer, vendor, main producer, competitor, and other interested party to draw up the “structure map of the basis for analysis of traditional craft industry”. Through the in-depth interview of operators and intermediary managers of craft brands to understand the commercial promotion strategy of traditional craft brands, and ultimately propose the factors of the digital ecosystem for traditional craft industry through integrating and inducting the result of the two surveys. The following are the six factors with those mechanisms: branding, high autonomy of establishing the brand image, low price selling platform, strengthen the exchanging of information and high credit sales. Through understanding of the promotion factors of the digital ecosystem for the traditional craft to help the craft industry to clarify the ecological chain in the commercial ecosystem; then propose the suggestion of the strategy for developing in the digital platforms era, and let the crafts industry could be permanent sustainable and self-renewal in the developing times of technology and information.

The author interviewed three chairpersons and five staffs, from five craft unions, to study the effects of implementing Taiwan TrainQuali System (TTQS) to craft unions’ in-service training programs. Based on the findings, the author concludes that 1. The implementation of TTQS enhanced staffs’ competences in handling training programs but they did not fully understand indexes and concepts of the system. 2. The evaluations of individual training programs only, instead of system wide, decreased the effects of training performance. 3. In-service training was helpful in increasing union members and their commitment. 4. In-service training was not unions’ major function due to governmental funding for training was not critical to unions’ survival. 5. Traditional mindset held by the Vocational Training Bureau hindered craft unions offering new and diverse training programs. 6. Craft unions’ could not create solid training transference for lacking of control to trainees’ working environment. 7. It’s difficult for craft unions to follow up the training performance of non-member trainees. Based on the above conclusions, the author suggests that 1. Craft unions should reposition in-service training as major function and enhance training evaluation to improve the quality of training programs. 2. Vocational Training Bureau should apply general terminology for TTQS indexes and concept, offer concise reasons for rejected programs, and accept training programs with developmental potential.

Taiwan's handcraft industry has experienced ups and downs in the process of development, and it now encounters the challenge to increase its added value. How to establish and manage branding in this section has become a critical issue. This research used system dynamics to conduct case studies on Liuligongfang, Franz, and Yii which successfully established their brandings with different models. For each case study we analyzed the branding process and identified its development model in different development stages. In the Liuligongfang case, due to limited budget, personal studio can’t produce works and spread its brand quickly. And also have an influence in initial positioning.In the Franz case, the company accumulated the human resources, capital, and design capability before developing its own brand. But the initial brand positioning will be influenced by its initial OEM/ODM development path.In the Yii case, the government supported program needs to create profit and feedback to the program itself in order to make it into a long-term business. And the timing of profit will determine the positioning of the brand. The results of the government supporting program case, the personal studio case, and the OEM/ODM/OBM transformation case, the development process is determined by the interactions of branding, quality, and value. New companies should choose proper model and strategy according to their existing resources and capabilities.

Children's Arts and Crafts Institutions provide an educational environment for art related knowledge and skills. The propositions of each Arts and Crafts institutions in the market are different, and curriculums of different purposes and nature have been created accordingly. In order to provide better arts and crafts education, it is necessary to differentiate and build unique images for each institution. This research analyzes information on Children's Arts and Crafts institutions' categories, brand positioning, brand identity and color systems. Base on the findings, we concluded that most Arts and Craft institutions are personally owned, and an integrated brand identity system would contribute substantially to communicate our brand in a competitive market place. The primary objective of this project is to establish the core value and brand positioning to differentiate our Arts and Crafts Institution with other Children's Arts and Crafts Institutions in the market. Base on our brand positioning, a brand name, CIS system will be created to communicate the educational vision and goals of our institution.

Abstract:

Marine search and rescue activities have been plagued with the problem of risking the lives of rescuers in rescue operations. With increasing developments in sensor technologies, it became a necessity in the marine search and rescue community to develop an autonomous marine craft to assist in rescue operations. Autonomy of marine craft requires a robust localization technique and process. To apply robust localization to marine craft, GPS technology was used to determine the position of the marine craft at any given point in time. Given that the operational environment of the marine was at open air, river, sea etc. GPS signal was always available to the marine craft as there are no obstructions to GPS signal. Adequate cognizance of the current position and states of an unmanned marine craft was a critical requirement for navigation of an unmanned surface vehicle (USV). The unmanned surface vehicle uses GPS in conjunction with state estimated solution provided by inertial sensors. In the absence of the GPS signal, navigation is resumed with a digital compass and inertial sensors to such a time when the GPS signal becomes accessible. GPS based navigation can be used for an unmanned marine craft with the mathematical modelling of the craft meeting the functional requirements of an unmanned marine craft. A low cost GPS unit was used in conjunction with a low cost inertial measurement unit (IMU) with sonar for obstacle detection. The use of sonar in navigation algorithm of marine craft was aimed at surveillance of the operational environment of the marine craft to detect obstacles on its path of motion. Inertial sensors were used to determine the attitude of the marine craft in motion.

Abstract This study mainly explores the dilemma of advancing the Employees' Welfare Funds System and takes business units and craft unions of Kaohsiung City for example. Firstly, this study analyzes the relevant literature review, survey data, the past history of employee welfare system and secondary data, and describes the practicing scope of employee welfare system, depositing and keeping the welfare fund, the organization of the employee welfare fund, and the controversy while monitoring the fund. This study also describes the practicing profile in Kaohsiung City and around the country by statistical data, especially the current situation that about 85% of business units haven’t established the employee welfare system legally. Secondly, this study, through in-depth interview, further investigates the dilemma of functioning the employee welfare system advancement, the reason why business units don’t legally establish the employee welfare institutions, and how craft unions advance the employee welfare system. To summarize the literature review, survey data, secondary data, and interview analyzing, we submit the following conclusions according to the dilemmas: 1.There is significance of employee welfare system on fundamental labor security. 2.The provision of welfare package exists in business units prevalently. 3.Employee welfare should have legal substantial effectiveness. 4.Employee welfare system should continually exist, but should be revised according to fulfilling problems and labor needs. 5.The government should take charge of advancing the employee welfare system. This study, aiming to the practices and how the government should enhance to advance the employee welfare system, draws the following four suggestions: 1.Simplify the applying procedure of the employee welfare committee, and adapt the established welfare items to legal systems. 2.The primary goal is to increase the establishing rate of employee welfare institutions, and then augment the practicing scope of employee welfare, fulfill the regulations, and improve the fundamental security of labor welfare. 3.By providing craft unions financial support, assisting craft unions to conduct employee welfare, the Employee Welfare Fund Law would, in turn, be well implemented. 4.The security of the non-typical employment rights should be considered while advancing employee welfare system.

The primary purpose of this study is to understand the assistance of stationing micro-craft brands in creative cluster to act as future reference for organizers of creative clusters. The study will focus on 3 directions of research: 1, operation status of stationed brands; 2, the effective operation models of creative clusters; 3, the assistance that creative clusters can give to “stationed brands”. 4 craft brands in the “Zhai-Xing” clusters supported by the municipal government will be selected as subjects while representatives will be selected for interview. The following are conclusions: 1, Of the 4 subjects, 1 brand has dropped out while the remaining 3 selected to stay. Reasons that influenced craft brands to continue their station include 5 factors:(1)Whether there are partners within the base that can assist in strengthening operations or providing resource assistance, (2)Whether target customer groups in the base fit the brand’s target audience or if the brand contains sufficient flexibility to make micro adjustments to products and comply with the characteristics of their audience, (3)Configuration of space and whether there is compliance to the operations of their specific industry, (4)Whether government or settlement operators contain integrated contact windows that can provide assistance to various problems instantly or in a timely manner, (5)Whether public department projects restrict the long-term development of stationed brands. 2, Effective operation models of creative clusters require that appropriate cluster operators are found during the planning stage. Effective and sustained operation and management that provides support for brands in the cluster can further help these brands to grow. 3, There are a few key factors as to whether creative settlements can assist stationed craft brands: (1)Effective settlement operators, (2)Operators must understand the brand development models of stationed businesses to provide appropriate assistance, (3)In actuality, the role of government in creative settlements focuses on “equality” rather than stable individual development in the creative industry.

Dissertação de Mestrado em Engenharia e Gestão Industrial apresentada à Faculdade de Ciências e Tecnologia
A gestão de custos tem vindo a ganhar uma importância cada vez maior dentro das organizações, uma vez que, através de uma boa gestão, é possível assegurar a sobrevivência das organizações face a um mercado cada vez mais aberto e competitivo. Se esta discussão é válida para as grandes empresas, para as de menor dimensão e com menos recursos disponíveis adquire ainda maior relevância visto que a margem para erros é, naturalmente, menor.No presente trabalho pretende-se proceder à implementação de um sistema de custeio por absorção baseado em atividades numa pequena empresa de fabrico artesanal de cerveja da região de Coimbra, tendo como objetivo caracterizar, quantificar e imputar todos os custos e rendimentos aos produtos comercializados. A análise aos resultados evidenciou o que já era conhecido, que a empresa está a operar com prejuízo económico. Face a isto, efetuou-se uma análise de sensibilidade face ao volume de produção, através da qual se obteve o nível crítico de produção. Identificaram-se ainda fatores de produção com preços de aquisição aparentemente acima do que era expectável, os quais devem ser alvo de atenção, nomeadamente de identificação de fornecedores alternativos.Para além de caraterizar detalhadamente a situação atual de produção da empresa, a informação produzida neste estudo permitiu ainda planear uma solução de produção alternativa, passível de ser atingida, que, a ser implementada, irá conduzir a empresa para uma situação economicamente favorável.
Nowadays, cost management. has been gaining relevance in businesses, since it is possible to ensure the survival of these in face of an increasingly competitive and open market through good management. If this is valid for larger corporations, for smaller ones with less resources available this is even more important, since the room for error is smaller.This work presents the implementation of an activity-based costing system in a small company from the region of Coimbra which produces craft beer, having as objective the characterization, quantification and imputation of every cost and revenue for the commercialized products. The analysis of the results showed what was already known - the company is operating with an economical loss. Due to this, a sensibility analysis to the production volume production was performed and the critical amount of production were determined. Production factors with an estimated acquisition price above what was expected were identified, which should be taken into attention, namely the identification of alternate suppliers.Besides characterizing with detail, the current production situation for the company, the information produced in this study allowed for the planning of an alternate production solution, within reach that with implementation will lead the business to a favourable economic situation.
