Full textAbstract:
A Factor Graph (FG -- http://en.wikipedia.org/wiki/Factor_graph) is a structure used to find solutions to problems that can be represented as a Probabilistic Graphical Model (PGM). They consist of interconnected variable nodes and factor nodes, which iteratively compute and pass messages to each other. FGs can be applied to solve decoding of forward error correcting codes, Markov chains and Markov Random Fields, Kalman Filtering, Fourier Transforms, and even some games such as Sudoku. In this paper, a framework is presented for rapid prototyping of hardware implementations of FG-based applications. The FG developer specifies aspects of the application, such as graphical structure, factor computation, and message passing algorithm, and the framework returns a design. A system of Python scripts and Verilog Hardware Description Language templates together are used to generate the HDL source code for the application. The generated designs are vendor/platform agnostic, but currently target the Xilinx Virtex-6-based ML605. The framework has so far been primarily applied to construct Low Density Parity Check (LDPC) decoders. The characteristics of a large basket of generated LDPC decoders, including contemporary 802.11n decoders, have been examined as a verification of the system and as a demonstration of its capabilities. As a further demonstration, the framework has been applied to construct a Sudoku solver.Master of Science

Full textAbstract:
This thesis seeks to extend the PDG methodology by developing a generalized formal method for nesting PDGs in an interconnected system. A procedure for decomposing an individual PDG into reusable modules will be defined and a software architecture will be presented which takes advantage of these reusable modules. This method breaks the PDG structure into discrete elements known as PDG objects, PDG modules and PDG services. Each of these elements forms a distinct unit of reuse and each can be seen as a "little" PDG. Two different industrial implementations of this method are presented. These examples show that it is possible to share PDG services amongst multiple PDGs and provide a mechanism to create a PDG for a complicated system.

Full textAbstract:
Decisions Support Systems (DSSs) are used to enhance decision maker speed and effectiveness. However, without a view of an entire system, any decision may have unanticipated effects such as sub-optimal outcomes. The purpose of this research is to show that with a system-level analysis, more informed decisions can be made that take into account a larger system or greater number of dimensions or objectives. This research also explores the benefits of using a DSS over analysis of unprocessed data and the effectiveness of integrating a product design generator (PDG) with a business DSS, creating a system DSS, where system-level effects can be analyzed. These are connected using software which allows them to be interactive, and dynamically updating. After this DSS was developed a variation was also made and decision makers evaluated these tools to identify how they performed in comparison to each other. In one variation, aspects of the tool were split up, guiding the decision maker through the analysis while the other did not. Using survey questions and recording decision makers' actions, it was found that decision makers are significantly faster and came to better conclusions when using the DSS over unprocessed data. However, it was also seen that the difference between the two variants of the System DSS tests was insignificant. This suggests that the limits in potential interactions in the one variant of a system DSS did not substantially reduce the ability of a decision maker to explore and make good design decisions. Overall this research showed that having a system-level tool is better than the unprocessed data, and that more extreme differences in a DSS are required for improved comparisons to establish which visualizations and elements are most effective in a System DSS. Future effort should be made to completely isolate different portions of the System DSS and see how well users are able to make decisions with it compared to the full system analysis.

Full textAbstract:
This diploma thesis is focused on the design of a product family of portable veterinary x-ray generators. The thesis deals with the possibilities of using parameterization when designing products which are part of a product series. The main body of the thesis lies in the design of a parametric script which generates variations of portable veterinary x-ray generators depending on the size and position of the inner components. The outer surfaces are defined by algorithms from the input parameters. It is possible to alter the individual attributes (e.g. the progresion of curves, the dimensions of component parts and the proportions between the individual parts). The output from the parametric script is three size-variations of the product.

Full textAbstract:
Today the county councils in Sweden prescribe rollators, but in the near future, the retail market for rollators will increase simultaneously with increased pressure within customer requirements. Among the users there is an increased awareness and urge to have a rollator that is up to date according to today’s development of the society. Which the current rollators on the market does not do. The demands from the customer have therefore started to change and are increasing within the coming generations. This is a result of the availability and possibility of all types of information regarding the subject. This means that there is a gap on the market that is growing, which leaves room for developing of a new product, to be able to keep up with technological progress. The goal was to deliver a reasonable concept proposal for a new rollator that with further development could be taken on to the next phase of development and production. The work also aims to clarify the next generation’s customer demands. Identify the issues surrounding today's prescriptions of rollators, as well as clarify the values that are imbedded in the product. The work has been based on a method called Pretzel, which is a product developing process developed by the company Scalae. Mapping of the society's value and norms connected to the rollators shows that the biggest problem among people is the early acceptance of the aid, this results in late prescribing of rollators. Which means that unnecessary injury often occurs, that is in not only unfortunately for the injured person but also a big cost for the society. Especially in comparison with the prescription cost of a rollator. These problems are thereby deep-rooted in values that closely connected to the slow development of rollators. The technological development today is extremely fast and new products are launched on the market at increasingly speed. For example, it would be very unusually to have the same model of mobile phone as your mother had when she was young. But when it comes to rollators, it is most possible that you may get the same model as your grandmother. To decrease the resistance against rollators the final concept is inspired by existing products on the market that already are accepted by the society. Although in other contexts, such as strollers and shopping carts. By using design and functions that the user is already are familiar with reach acceptance faster and reduce the risk of injuries. The final concept is called the Dramator and is a hybrid between a shopping cart and a rollator.Idag förskrivs rollator av Landstingen samt kommuner, men inom en snar framtid kan marknaden för retail komma att öka radikalt i samband med att kraven från kunden ökar. Det råder en allt mer ökad medvetenhet och en vilja hos kunden att få en produkt som hänger med i samhällets utveckling, vilket dagens rollatorer inte gör. Då möjligheten och tillgängligheten till all sorts information ökar bidrar detta till att framtida generationer kommer att ställa högre krav på produkten än vad som ställs idag. Detta innebär att det just nu håller på att bildas ett glapp på marknaden och att en ny produkt som hänger med teknikens framfart måste utvecklas. Målet var att komma fram till ett konceptförslag, som sedan skulle kunna tas vidare till nästa fas för vidareutveckling och produktion. Arbetet syftar även till att bringa klarhet i kundkraven hos nästa generation och problem kring dagens förskrivningar, samt klarlägga värderingar som råder kring produkten. Arbetet har utgått från en metod som heter Pretzel, som är en process för degenerering och produktutveckling framtagen av företaget Scalae. Kartläggningen av värderingarna och samhällets syn på rollatorn, visar på problem som resulterar i att många rollatorer utskrivs försent. Detta innebär att onödiga personskador hinner uppkomma som i sin tur kostar samhället mycket pengar i jämförelse med förskrivningskostnaden av en rollator. Problemen ligger djup rotade i värderingar som går hand i hand men den långsamma utvecklingen av rollatorer. Den tekniska utvecklingen går idag oerhört fort och nya produkter lanseras på marknaden med rasande fart. Att till exempel ha samma mobiltelefonmodell som sin mamma är i dagens samhälle högst orimligt, men när det gäller rollatorer kan du till och med få samma modell som din farmor hade.Konceptet är inspirerat av existerande produkter på marknaden som är socialt accepterande, fast i andra sammanhang, så som barnvagnar och klassiska Dramaten-väskan. Genom att använda formspråk och funktioner som användaren redan är bekant med är målet acceptansprocessen för användaren kan kortas ner så att hjälpmedlet kan börja användas i tid och på så sätt minska risken för fallskador. Det slutliga konceptet kallas för Dramatorn och är en hybrid mellan en dramatenväska och en rollator.

Bongard, Kerstin. "Bringing the user experience to early product conception : From idea generation to idea evaluation." Phd thesis, Paris, ENSAM, 2013. http://pastel.archives-ouvertes.fr/pastel-00936893.
Full textAbstract:
The User Experience (UX) has become a major concern for the design of consumer products. Today exist various tools for the evaluation of static properties of final products on their User Experience value. However, very few tools and methods are available that allow anticipating the future User Experience during the first stages of product conception. This thesis explores the wide range of design dimensions that potentially form the experience of the user. Dynamic product properties emerge as an important factor for User Experience. In the studies a software based on inspiration words and links, as well as the technique body storming are tested as a new means of User Experience generation. The produced early concepts and interaction gestures are then evaluated through a combination of questionnaires, behavioural and physiological measurements. The study results show firstly that a wide range of design dimension needs to be regarded to design for User Experience, secondly that it is possible to apply UX evaluations on early concepts and thirdly that UX evaluations can also be done on dynamic properties like interaction gestures. This thesis furthermore contributes design research and practice with a new model on the mechanism of User Experience and a list of design dimensions for early product conception.

A methodology for the optimal design and operation of microfabricated fuel cell systems is proposed and algorithms for relevant optimization problems are developed. The methodology relies on modeling, simulation and optimization at three levels of modeling detail. The first class of optimization problems considered are parametric mixed-integer linear programs and the second class are bilevel programs with nonconvex inner and outer programs; no algorithms exist currently in the open literature for the global solution of either problem in the form considered here. Microfabricated fuel cell systems are a promising alternative to batteries for manportable power generation. These devices are potential consumer products that comprise a more or less complex chemical process, and can therefore be considered chemical products. With current computational possibilities and available algorithms it is impossible to solve for the optimal design and operation in one step since the devices considered involve complex geometries, multiple scales, time-dependence and parametric uncertainty. Therefore, a methodology is presented based on decomposition into three levels of modeling detail, namely system-level models for process synthesis,
(cont.) intermediate fidelity models for optimization of sizes and operation, and detailed, computational fluid dynamics models for geometry improvement. Process synthesis, heat integration and layout considerations are addressed through the use of lumped algebraic models, general enough to be independent of detailed design choices, such as reactor configuration and catalyst choice. Through the use of simulation and parametric mixed-integer optimization the most promising process structures along with idealized layouts are selected among thousands of alternatives. At the intermediate fidelity level space-distributed models are used, which allow optimization of unit sizes and operation for a given process structure without the need to specify a detailed geometry. The resulting models involve partial differential-algebraic equations and dynamic optimization is employed as the solution technique. Finally, the use of detailed two- and three-dimensional computational fluid dynamics facilitates geometrical improvements as well as the derivation and validation of modeling assumptions that are employed in the system-level and intermediate fidelity models. Steady-state case studies are presented assuming a constant power demand;
(cont.) the methodology can be also applied to transient considerations and the case of variable power demand. Parametric programming provides the solution of an optimization problem, the data of which depend on one or many unknown real-valued parameters, for each possible value of the parameter(s). In this thesis mixed-integer linear programs are considered, i.e., optimization programs with affine functions involving real- and integervalued variables. In the first part the multiparametric cost-vector case is considered, i.e., an arbitrary finite number of parameters is allowed, that influence only the coefficients of the objective function. The extension of a well-known algorithm for the single-parameter case is presented, and the algorithm behavior is illustrated on simple examples with two parameters. The optimality region of a given basis is a polyhedron in the parameter space, and the algorithm relies on progressively constructing these polyhedra and solving mixed-integer linear programs at their vertices. Subsequently, two algorithmic alternatives are developed, one based on the identification of optimality regions, and one on branch-and-bound. In the second part the single-parameter general case is considered,
(cont.) i.e., a single parameter is allowed that can simultaneously influence the coefficients of the objective function, the right-hand side of the constraints, and also the coefficients of the matrix. Two algorithms for mixed-integer linear programs are proposed. The first is based on branch-and-bound on the integer variables, solving a parametric linear program at each node, and the second is based on decomposition of the parametric optimization problem into a series of mixed-integer linear and mixed-integer nonlinear optimization problems. For the parametric linear programs an improvement of a literature algorithm for the solution of linear programs based on rational operations is presented and an alternative based on predictor-continuation is proposed. A set of test problems is introduced and numerical results for these test problems are discussed. The algorithms are then applied to case studies from the man-portable power generation. Finally extensions to the nonlinear case are discussed and an example from chemical equilibrium is analyzed. Bilevel programs are hierarchical programs where an outer program is constrained by an embedded inner program.
(cont.) Here the co-operative formulation of inequality constrained bilevel programs involving real-valued variables and nonconvex functions in both the inner and outer programs is considered. It is shown that previous literature proposals for the global solution of such programs are not generally valid for nonconvex inner programs and several consequences of nonconvexity in the inner program are identified. Subsequently, a bounding algorithm for the global solution is presented. The algorithm is rigorous and terminates finitely to a solution that satisfies e-optimality in the inner and outer programs. For the lower bounding problem, a relaxed program, containing the constraints of the inner and outer programs augmented by a parametric upper bound on the optimal solution function of the inner program, is solved to global optimality. For the case that the inner program satisfies a constraint qualification, a heuristic for tighter lower bounds is presented based on the KKT necessary conditions of the inner program. The upper bounding problem is based on probing the solution obtained in the lower bounding procedure. Branching and probing are not required for convergence but both have potential advantages.
(cont.) Three branching heuristics are described and analyzed. A set of test problems is introduced and numerical results for these test problems and for literature examples are presented.

Full textAbstract:
Electronic engineering product design is a complex process which has enjoyed an increasing provision of computer based tools since the early 1980's. Over this period computer aided design tool development has progressed at such a pace that new features and functions have tended to be market driven. As such CAD tools have not been developed through the recommended practise of defining a functional specification prior to any software code generation. This thesis defines a new functional specification for next generation CAD tools to support the electronics product design process. It is synthesized from a review of the use of computers in the electronics product design process, from a case study of Best Practices prevalent in a wide range of electronics companies and from a new model of the design process. The model and the best practices have given rise to a new concept for company engineering documentation, the Product Book which provides a logical framework for constraining CAD tools and their users (designers) as means of controlling costs in the design process. This specification differs from current perceptions of computer functionality in the CAD tool industry by addressing human needs together with company needs of computer supported design, rather than just providing more technological support for the designer in isolation.

Orthopedic surgery is dangerous, especially for the surgeon! Tool failures belong to the ten most frequent causes of operation delays. Nowadays, hospitals are pressured to optimize procedures and lower costs. Especially, orthopedic surgery is physically demanding for the ergonomics of the surgeon and tools wear out more quickly. Could the evolution of a surgical power tool be used in these scenarios to ease and support the surgeons work, increase the efficiency and flexibility of usage and at the same time offer more control and knowledge about the condition of the tools?

It is widely recognized that innovation and creativity is the new competitive battleground for product development firms. Engineers and product designers are now expected to be highly creative, prolific idea generators in addition to being analytically competent. Thus, it is of interest to study methods to improve a designer's idea generation capabilities. It is believed that wit, being spontaneous humor production, is strongly related to creativity as both involve making nonobvious connections between seemingly unrelated things. This thesis looks into the realm of humor and improvisational comedy to suggest means of enhancing creative output in blue-sky product design idea generation. We have found that the ability to quickly generate many ideas is strongly correlated (r2=.82) with being able to come up with a single, promising, creative idea. It was also found that, with appropriate training, individuals may learn to become more prolific idea generators. Furthermore, improvisational comedians were more proficient at new product idea generation than professional product designers, and methods for training comedians can be effectively adapted to product design idea generation. In a study where 84 participants (students, professional designers and improvisational comedians) took a cartoon caption humor test and a nominal product brainstorming test, we found that improvisational comedians on average produced 20% more product ideas and 25% more creative product ideas than professional product designers. Furthermore, the few individuals that were highly prolific in both creative product ideation and humorous cartoon caption production had an improvisational comedy background. Many of the games used in improvisational comedy training are intended to promote associative thinking. We designed an improvisational comedy workshop composed of these association-based games. A group of 11 subjects who participated in this workshop increased their idea output on average by 37% in a subsequent product brainstorming session. Our findings suggest that improvisational comedy games are a useful warm-up for idea generation, that prolific generation is not a domain-specific ability and that it is possible to teach creativity. Ultimately, this work can lead to the development of tools and methods that designers can use to improve their idea generation skills.

Some of the world's most challenging problems will require distributed innovation capacity in order to create high-quality and sustainable solutions. However, access to prototyping resources varies and design strategies that are optimal in one context may be suboptimal in another. As the engineering practice is becoming increasingly globalized and R&D laboratories in universities and firms around the world try to maximize innovation with a limited set of resources, there is a need for greater understanding of the impact of prototyping resource environments on product design in universities. This knowledge will allow for the creation of more efficient innovation systems and help to foster more adaptable engineers. In order to explore the relationship between available resources for prototyping and idea generation during the design process, multiple embedded case studies were conducted with engineering students and professors at two university campuses in Mexico. In a design experiment, students developed sketches for products that would satisfy an open-ended design problem in a constrained-resource setting, where the variables were the timing of when information about these constraints was revealed, and the regular prototyping environment of the student. The outcomes were evaluated by comparing metrics such as the quantity, novelty, appropriateness, technical feasibility and marketability of the concepts. The evidence suggests that the timing of constraints can have an impact on the design outcomes, but that this effect varies depending on the designer's regular prototyping environment. The implications of these findings for engineers, educators, and policymakers working in any setting are discussed.

Full textAbstract:
The overall aim throughout the project was to outline a new modular platform for a future generation of ventilators as well as designing a ventilator based on the defined platform. Doing so through a conceptual approach, looking at enabling cost efficient development, manufature and product scalability as well as taking the users needs for flexibility, improved usability, cable management and transport into consideration. The project used a traditional user centric design approach while also having a strong manufacturers focus when it came to looking at modularity and the company’s product offering. The main insights throughout the project revolved around looking at the entire ecosystem of products and how they worked together in the intensive care unit (ICU). Understanding the core struggles and time consuming tasks in order further improve the workflow in the ICU. A big part of the ideation and concept development process was spent on building rough mock-ups for fast evaluation together with users and the collaborating partner. The result was a combined, highly modular, ventilator and monitoring system called Servo One. With a new tubing system that incorporated both humidifier and patient filter in a flexible way, together with an external sensor system, the concept drastically improved cable and tubing management - one of the biggest challenges in the ICU.

Full textAbstract:
This thesis documents research undertaken into the design and evaluation of a computer tool (Colour Concept Generator) to produce colour schemes for products from verbal descriptors depicting a required aesthetic image or style. The system was designed to translate between descriptive words and colour combinations and aims to provide a form of ideas stimulus for a product designer at the initial stages of the design process. The computer system uses elements of artificial intelligence (AI) to `learn' colour and descriptor semiotic relations from a product designer based upon a proposed objective criteria or to reflect a designers personal style. Colour concepts for products can then be generated from descriptors based upon these semiotic relations. The philosophy of the research is based upon the idea of computing colour aesthetics at the front end of the design process and the design of an Al software mechanism to facilitate this. The problem was analysed with respect to the available literature on colour and a set of detail requirements for the system were presented. The system was then designed and code based upon the requirements and evaluated in terms of the overall philosophy, system methodology and application of computer media. The research is a contribution to the field of computer aided design regarding colour aesthetics and demonstrates the possibility of using an artificial intelligent machine to inspire and stimulate creative human thought. The Al software mechanism of the Colour Concept Generator is presented as an application of Al to aesthetic design. 11

This dissertation includes two process modeling studies -- (1) predictive modeling of large-scale integrated refinery reaction and fractionation systems from plant data – hydrocracking process; and (2) integrated process modeling and product design of biodiesel manufacturing. \r\n1. Predictive Modeling of Large-Scale Integrated Refinery Reaction and Fractionation Systems from Plant Data -- Hydrocracking Processes: This work represents a workflow to develop, validate and apply a predictive model for rating and optimization of large-scale integrated refinery reaction and fractionation systems from plant data. We demonstrate the workflow with two commercial processes -- medium-pressure hydrocracking unit with a feed capacity of 1 million ton per year and high-pressure hydrocracking unit with a feed capacity of 2 million ton per year in the Asia Pacific. This work represents the detailed procedure for data acquisition to ensure accurate mass balances, and for implementing the workflow using Excel spreadsheets and a commercial software tool, Aspen HYSYS from Aspen Technology, Inc. The workflow includes special tools to facilitate an accurate transition from lumped kinetic components used in reactor modeling to the boiling point based pseudo-components required in the rigorous tray-by-tray distillation simulation. Two to three months of plant data are used to validate models' predictability. The resulting models accurately predict unit performance, product yields, and fuel properties from the corresponding operating conditions.\r\n2. Integrated Process Modeling and Product Design of Biodiesel Manufacturing: This work represents first a comprehensive review of published literature pertaining to developing an integrated process modeling and product design of biodiesel manufacturing, and identifies those deficient areas for further development. It also represents new modeling tools and a methodology for the integrated process modeling and product design of an entire biodiesel manufacturing train. We demonstrate the methodology by simulating an integrated process to predict reactor and \r\nseparator performance, stream conditions, and product qualities with different feedstocks. The results show that the methodology is effective not only for the rating and optimization of an existing biodiesel manufacturing, and but also for the design of a new process to produce biodiesel with specified fuel properties.Ph.

Full textAbstract:
The notion of sustainability has become an extensive area of research ever since the term emerged in the late 1980s, due to the negative effects of unsustainable production and consumption patterns on environmental stewardship, social equity and economic development. There have been various approaches developed for product design and education within the context sustainability. Biomimicry is one of those approaches, and its implications for product design education have recently started to be explored. In this study, an educational tool - Biomimicry Sketch Analysis (BSA) - was developed and integrated into the idea-generation phase of an educational design project at the undergraduate level in the Department of Industrial Design at the Middle East Technical University (METU). This integration is analyzed throughout the graduate thesis study, to understand and explore the implications of the biomimicry approach for sustainability in product design education. The educational tool within this approach was found as influential among the third year industrial design students for the idea-generation phase, yet the results of this study included both pros and cons for the incorporation of the BSA exercise.

This study sought to determine whether there exist identifiable patterns for how ideas are generated using rapid prototyping and sketching tools during a talk-aloud protocol. Three designers' work, as they engaged in a hands-on design activity, were tracked in this experiment. Recordings of their activity were reviewed, and revealed that certain themes are prevalent in the way people design: memories, context, familiarity and innovation. As well, patterns for brainstorming were uncovered: the first identifiable pattern began with the designers drawing from memory, and the other was anchored in the designers' quest to innovate. Finally, the format of the experiment itself seemed to have played a role in the design process. This was observed in the number of designs created by each participant, and by the timing of each breakthrough thought or idea.

Full textAbstract:
Industries want to add value to their offerings but to do this, rather than just accepting customer requirements, they now need to know how their products and/or services have been embedded within their customer’s process to achieve a goal that the customer has; any gaps within the process then present an opportunity for the provider to fill these gaps.
The System-In-Use (SIU) Methodology presented in this thesis facilitates customer issues in “pulling” the supply chain into creating new solutions as well as the supply chain “pushing” new value propositions into improving customer processes. It does this by drawing on a detailed theory of value and capability which was developed as part of this research.
The method has been applied in five industries in processes encompassing high value-assets with very positive outcomes for each of the stakeholders involved: notably, three solutions have been adopted in industry for which a KT-Box award was granted by Cambridge University. Cont/d.

Full textAbstract:
User-Centred Design (UCD) was proposed in the 1980s and, since then, its philosophy has helped to solve design problems, regardless of the advances in technology over time. The standard ISO 9241:210 (2010), formerly ISO 13407, provides guidance in human-centred design principles and activities undertaken throughout the design lifecycle to further support UCD. In addition, since it was mentioned in ISO 9241:210, UCD has also utilised User Experience Design (UXD) in recent years. There are many approaches that support UCD to ensure it is more attainable when designing. In addition, large firms, such as HP, IBM and Microsoft, use anthropologists in their user research in order to make products more user-centred. However, the concept of UCD should, theoretically, be more widely used in all product design and it is intriguing as to why it is not as popular as it should be. As noticed in the real world, imperfect designs still frustrate us everywhere. The aims of this thesis were to investigate the difficulties of practicing a UCD approach in idea generation and to design solutions for idea generation that would encourage further practice of UCD/UXD. In the first part of the thesis, there is an exploration of the problems encountered when practicing UCD idea generation. When examining the process, a multitude of problems were found, with most blamed as being costly, time consuming and requiring complex skills. In addition, it was suggested that a systematic solution was required to overcome such difficulties. Therefore, later in this research, a systematic model is proposed and evaluated using participants (both designers and target users). Due to the fact that design practitioners are not usually researchers, further help to implement the model in the form of persona application software is needed. Hence, the concept of service design was employed to further assist with the use of the model. In the end, computer-aided development was introduced, together with the integration of the systematic UCD model. The UCD model and the software have been evaluated as effective from both the responses of product design practitioners and end-users. Future recommendations and the research limitations are also discussed in each chapter and the overall results are given in the last chapter. This thesis successfully provided the complete process during the exploration of the low usage problems of UCD, and solutions were presented to assist designers with their UCD/UXD in the future.

For the automotive industry, to be competitive in the market place has to devise many strategies. Some of the prominent strategies include and are not limited to, reduction of development costs by moving in-house work to its suppliers, reduction of PD cycle time by mimicking some of the industry's successful PD processes. Some companies are also devising some complex strategies like Zero-Prototype development using computer aided prototyping and testing, currently prevalent in the aerospace and naval industries, and more recently making a move into the Lean PD systems and processes to avoid waste and increase efficiency. However, to introduce such lean PD systems, with reduced PD cycle time, into a complex organization with many internally developed IT systems, processes and tools is a huge challenge. The organization needs to adapt to these lean environments not just structurally but also culturally. To design a lean PD organization (system) the decision makers have to foresee and understand how the system of systems may react to the change before they are implemented and/or executed. In the past couple of decades IT systems have been a primary enabler for PD work flow processes.
(cont.) However, IT systems are so engraved in some PD organizations that they have turned into an engineering process mechanism. Also, some of the IT systems have served more than their life expectancy and in some cases cannot be decommissioned because these systems are so tightly coupled with the business processes. An understanding of the internal system dynamics of these deeply engraved IT systems in the PD life cycle will help the automotive industry executives (decision makers) and IT systems architects to make the right decision when designing and deploying the new PD systems or processes. This study provides an overview of how IT tools have evolved in the automotive industry. Extensive research was conducted to understand the different system dynamics tools used in industry - specifically in automotive product development and the software development areas. The study concludes with an explanation of how system dynamics tools can be used as a program planning and management tool.

Full textAbstract:
The regulations on emissions from a combustion engine vehicle are getting tougher with increasing awareness on sustainability, requiring the exhaust after-treatment systems to constantly evolve to the changes in the legislation. To establish a leading position in the competitive market, companies must adapt to these changes within a reasonable timeframe. With Scania’s extensive focus on Simulation-driven design, the product development process at Scania is highly iterative. A considerable amount of time is spent on generating a specific model for a simulation from the existing Computer-aided Design (CAD) model and pre-processing it. Thus, the purpose of this thesis is to investigate how design and simulation teams can collectively work to automatically generate a discretized model from the existing CAD model, thereby reducing repetitive work. As an outcome of this project, a method is developed comprising of two automation modules. The first module, proposed to be used by a design engineer, automatically generates a simulation-specific model from the existing CAD model. The second module, proposed to be used by a simulation engineer, automatically discretizes the model. Based on two case study assemblies, it is shown that the proposed method is significantly robust and has the potential to reduce product development time remarkably.

Full textAbstract:
This master thesis describes a project during which a new product was developed that will measure the wear of a high pressure feeder in the conventional feeding line in a paper mill. The product will also be industrialized so that it can be manufactured in smaller series. previously, wear has been measured with a metal scale where the operator read the values and documented them manually. The goal of this project was to develop the mechanical parts of a product that will automatically measure the wear distance, gather the information and present the data. The project followed the classic product development process that was slightly modified to fit this specific project. A pre-study of the market and the current product gathered the information needed to generate a large number of concepts. The concepts were then eliminated in order to select the final concept that was the best solution for the problem based on the requirements given by the company. Once the concept was chosen it was modelled using a CAD-software (Compute Aided Design). Most of the components are standard components that can be “bought off the shelf”, which means that it should not be too many special parts that will cost a lot of money and time to manufacture. The product is also IP67-classified which means that it can manage the water and white liquor (mainly sodium hydroxide and sodium sulphide) that are present in a conventional feeding line in a paper mill. The result consists of a description of the final product. The company have also been provided with CAD-files and a manual on how to build the product. The company have also been provided with a list of all the standard components and where to buy them. During the project, some of the requirements have been changed by the global development team which made the project harder and the final product is different from the initial thought. However, the goal was reached, and the company have information and concept to use as inspiration for the next generation of this product. The final product is a robust box that can easily be mounted onto the high pressure feeder. The lower part of the box consists of the mechanical parts that are linked to the electrical parts which are in the upper part of the box.Det här examensarbetet är ett project där en ny produkt har tagits fram som mäter förslitningen på en högtryckskik i det konventionella flödet i ett pappersbruk. Produkten skall också vara industrialiserbar så den kan tillverkas i en mindre serie. Tidigare har det varit en stållinjal som operatören läser av och dokumentarer värdena manuellt. Målet var att utveckla de mekaniska delarna på en produkt som automatiskt mäter förslitningen, samlar informationen och presenterar datan. Projektet följde den klassiska produktutvecklingsprocessen som var lite modifierad för att passa detta specifika projekt. En förstudie av marknaden och den nuvarande produkten fick ihop den informationen som krävdes för att ta fram ett flertal koncept. Koncepten var sedan eliminerade tills det endast var ett koncept kvar som är det optimala konceptet baserat på de krav som företaget har ställt. När det slutliga konceptet var bestämt visualiserades det med hjälp av CAD. Alla komponenter är standard- komponenter som kan ”plockas direkt från hyllan”, vilket betyder att det inte skall vara några specialtillverkade delar som kostar mycket pengar och tid för att göra det lättare att industrialisera produkten. Produkten är också IP67-klassifierad vilket betyder att den kan klara av vattnet och kemikalierna i ett pappersbruk. Resultatet består utav en verbal beskrivning av den slutliga produkten. Företaget har blivit försedda med CAD- filer och en manual för hur man skall bygga produkten. Företaget har även blivit försedda med en lista över alla komponenter samt vart dom går att köpa. Under projektets gång har några krav ändrats utav det globala utvecklingsteamet vilket gjorde projektet svårare samt att den slutliga produkten inte blev likt den initiala tanken. Målet nåddes och företaget har även information och koncept som kan användas som inspiration inför nästa generation av produkten. Den slutliga produkten är en robust låda som lätt kan monteras på högtryckskiken. Den nedre delan av lådan består utav det mekaniska delarna som är kopplade till de elektroniska delarna som är i den övre delen av lådan.

Full textAbstract:
This master thesis treats the development of a new component in a tidal energy power plant. The technology that the component should be used in extracts energy from tidal an low velocity currents. This is done by that a turbine is placed on a kite which is pushed forward in the water due to the lifting force acting on the wing. A tether connects the kite with a bottom joint that is placed on a foundation at the seabed. The bottom joint used today is heavy and expensive, which was the main reason to that this thesis was initiated. In this work, the possibility of using a polymer based design for the connection between the tether and foundation was investigated. The optimal outcome of the project was that the polymer solution should provide a spring function to the power plant. A lot of conventional product development methods have been used in the project. The project was divided into five parts: planning, product specification, concept generation, concept choice and conceptual design. In order to understand what was required of the solution in terms of the spring function, a model that aimed to represent what effect a spring function would have on the power plant was developed. According to the model, a spring function in the tether direction could increase the velocity of the kite in its trajectory. The model is based on some simplifications which is assessed to need further investigation. The spring function was translated to that the component should be able to elongate as a response to the force acting in the tether direction. In the concept choice phase it was chosen to proceed with a design similar to that of a bend stiffener. It was decided that a spring function was not required of the component, though desirable. A material selection was performed and the most optimal material for a single part that should be able withstand the tension, allow rotation, and provide a spring function was concluded to be TPU(ester, aromatic, Shore 50D). In the attempt to understand what was needed to be considered if the spring function should be solved by a material response in a polymer component, relevant theory was collected. A numerical analysis in Abaqus was performed which indicated that such a solution was unreasonable. It was then decided to proceed with the development of a bend stiffener, where the tether should be connected directly to the foundation. The thesis finally concludes with a conceptual design of a bend stiffener. The most suitable material for a bend stiffener was concluded to be TPU(ether, aliphatic, Shore 60D). The initial dimensions were determined by the maximum angle and tension combination that the tether would be exposed to. A static analysis was performed in Abaqus to illustrate the function of the product. The analysis indicated that a bend stiffener could provide the required function. However, the stress in the component became high, which indicated that the bend stiffener material might fail due to the applied load. In order to fully evaluate this, it was concluded that a more accurate material model was required.

SEW-Eurodrive (SEW) är ett företag som tillverkar och säljer produkter inom området elmotorer, växellådor, decentraliserad elektronik, motion control (styrning av drivsystem), frekvensomformare och servosystem. SEW-Eurodrive har i dagsläget ett flertal olika demoutrustningar för att visa olika produkters funktioner för kunder på industrimässor. Under år 2017 lanserade SEW sin nya produktfamilj, MOVI-C, inom drivelektronik. På grund av detta har en ny en komplett demoutrustning för MOVI-C utvecklats i detta projekt för att visa upp funktionerna av produktfamiljen för kunder på industrimässor. Det var sedan tidigare bestämt av teknikavdelningen på SEW hur den nya produktfamiljen skulle demonstrera sina funktioner. Projektet började med att utveckla en kravspecifikation med de krav som ställdes på demoutrustningen. Det var krav så som att den ska passa i en transportlösning och på ett tydligt sätt visa vad som demonstreras. Utifrån denna kravspecifikation har sedan en konceptgenerering gjorts. För att hitta så många helhetskoncept som möjligt har problemet brutits ner i delproblem som sedan försöktes lösas med flera dellösningar. Dellösningarna utvärderas först enskilt för att eliminera olämpliga dellösningar. I samråd med teknikavdelningen på SEW valdes några helhetskoncept ut för vidare urval genom en viktad urvalsmatris. Den viktade urvalsmatrisen betygsatte de olika helhetskoncepten inom olika kriterier och genom detta har ett helhetskoncept valts ut. En 3D-modell skapades av det utvalda helhetskonceptet och enklare hållfasthetsberäkningar, tyngdpunktsberäkningar och projekteringsberäkningar gjordes. Tillverkningsunderlag i form av ritningar och beställningslistor har tagits fram av det helhetskoncept som urvalet resulterade i. Möjliga vidareutvecklingar av det resulterande helhetskonceptet är förstyvningsvinklar som skulle göra konstruktionen mer stabil samt undersöka lösningarna för transporthjul mer.SEW-Eurodrive (SEW) is a company that manufactures and sells products in the field of electric motors, exercise electric motors, gearboxes, decentralized electronics, motion control, frequency converters and servo systems. SEW-Eurodrive currently has a number of different demo equipment to show different product features for customers at industrial fairs. In year 2017, SEW launched its new product family, MOVI-C, in driving electronics. Because of this, a new, complete MOVI-C demo device has been developed in this project to show the features of the product family for customers at industry fairs. Before the project started the engineering department at SEW had already decided how the new demo device would demonstrate the new product family's functions. The project started with the development of a requirement specification for the demo unit. Among the requirements were that the demo unit would fit in a transport solution and clearly show what is being demonstrated. Based on this requirement specification, a concept generation was made. To find as many conceptions as possible, the main problem was broken down into sub-problems, in which multiple sub-solutions attempted to resolve. The sub-solutions were first evaluated individually to eliminate inappropriate sub-solutions. In consultation with the engineering department at SEW, some overall concepts were selected for the continued selection process through a weighted selection matrix. The weighted selection matrix rated the different concepts in a variety of criteria, and through this a whole concept has been chosen. A 3D model was created by the selected overall concept and simpler strength calculations, center of gravity calculations and design calculations were made. Manufacturing documentation in the form of drawings and order lists have been produced. Possible further developments of the resulting overall concept are stiffening angles that would make the structure more stable, as well as investigate the solutions for transport wheels more.

Full textAbstract:
Internet usage is increasing every year, and so do the different online activities on the internet. Online shopping is one of the most popular activities on the internet and is continuing to grow. This study investigated if visual information influences consumer behaviour on e-retail websites when shown together with non-imagery information. The study also looks at whether or not the visual information that is being presented is a factor for consumers behaviour, and if the quality of the image matters in purchase intent. Another point of view in this study was whether or not imagery information in e-retail would increase the consumer attitude towards the design and if the type of visual information mattered. A significant difference was found in purchase intent for products having imagery information, regardless of the quality. Attitudes towards e-retail designs with high-quality product images were also found to be significantly more positive over both no- and low-quality images. The findings of this study fills the gap whether or not visual stimuli influence consumers when displayed to products without visual stimuli. The type of product imagery information being displayed is also a factor for consumer enjoyment. High-quality visual information is perceived better compared to designs with low-quality and non-imagery product information.

Full textAbstract:
Companies are increasingly drawing on their user communities to generate promising ideas for new products,
which are then marketed as "user-designed" products to the broader consumer market. We demonstrate that
nonparticipating, observing consumers prefer to buy from user-rather than designer-driven firms because of an
enhanced identification with the firm that has adopted this user-driven philosophy. Three experimental studies
validate a newly proposed social identification account underlying this effect. Because consumers are also users,
their social identities connect to the user-designers, and they feel empowerment by vicariously being involved
in the design process. This formed connection leads to preference for the firm's products. Importantly, this
social identification account also effectively predicts when the effect does not materialize. First, we find that if
consumers feel dissimilar to participating users, the effects are attenuated. We demonstrate that this happens when the community differs from consumers along important demographics (i.e., gender) or when consumers are
nonexperts in the focal domain (i.e., they feel that they do not belong to the social group of participating users).
Second, the effects are attenuated if the user-driven firm is only selectively rather than fully open to participation
from all users (observing consumers do not feel socially included). These findings advance the emerging theory on
user involvement and offer practical implications for firms interested in pursuing a user-driven philosophy.

Insbesondere die frühen Phasen in Prozessen der Mechatroniksystementwicklung sind durch ein hohes Maß an Unsicherheit gekennzeichnet. Zu diesem Zeitpunkt des Produktentstehungsprozesses liegen lediglich vage und unscharfe Anforderungen an das Produkt vor, welche es zu konkretisieren gilt. Aktuelle Herausforderungen der Produktentwicklung haben einen verstärkenden Effekt auf die Unsicherheiten in frühen Entwicklungsphasen. Diesen begegnen Unternehmen aus dem Bereich der Mechatroniksystementwicklung zunehmend mit der Implementierung agiler Entwicklungsansätze in ihre etablierten Prozesse. Neben der frühen und kontinuierlichen Kundeneinbindung, der klare Ausrichtung der Prozesse auf die Wertsteigerung der Produkte aus Kundensicht, flachen und offenen Hierarchien und dem stetigen Aufbau und Weiterentwicklung von Prototypen verleihen meist geplante Iterationen den jeweiligen Projekten das Adjektiv „agil“. Die Vielfalt der in der Literatur beschriebenen und meist generisch formulierten Arten von Iterationen (geplant oder ungeplant, korrekturbezogen oder progressiv) ist jedoch sehr groß. Zudem werden Iterationen in der Praxis meist intuitiv und unbewusst durchgeführt, was zum einen dazu führt, dass das jeweilige Entwicklungsvorgehen nicht situationsoptimal ausgeführt wird oder gar hinsichtlich der Ergebnissynthese und –Analyse redundante Tätigkeiten erfolgen. Aus diesem Grund verfolgt das vorliegenden Forschungsvorhaben die Zielsetzung, einen Beitrag zur Unterstützung der Produktentwickler in frühen Entwicklungsphasen bei der Identifikation notwendiger Iterationen zu leisten. Durch eine Berücksichtigung dieser in der kurz- und mittelfristigen Projektplanung kann somit die Prozessunsicherheit reduziert werden.

Full textAbstract:
Beobachtungen der vergangenen Jahre zeigen, dass sich Unternehmen für die Entwicklung von Produkten zunehmend global verteilt aufstellen (Lindemann und Kern 2016). So bieten verteilt arbeitende Teams neben potenziellen Kostensenkungen und kürzeren Entwicklungszeiten auch die Möglichkeit, Synergieeffekte effektiv nutzen zu können. Insbesondere für die Entwicklung immer komplexer werdender Produkte, die an der Schnittstelle von Maschinenbau, Elektrotechnik oder Informatik entstehen, ist die überregionale Zusammenarbeit von Experten aus den verschiedenen Bereichen notwendig (Bavendiek et al. 2018a). Erst die Kooperation in verteilten Teams erlaubt es, das weltweit verteilte Know-How zu bündeln. Um den Produktentwicklungsprozess bedarfsgerecht zu unterstützen existiert eine Vielzahl von Methoden, die in den vergangenen Jahren einen immer größer werdenden Stellenwert in der Industrie erlangt haben. Trotz ihrer empirisch nachgewiesenen Vorteile für die Produktentwicklung (Graner & Behr 2012) lässt sich in der Praxis oftmals nur ein zögerlicher Methodeneinsatz beobachten (Gericke et al. 2016). Gerade in verteilten Entwicklungsprojekten stellt sich der Methodeneinsatz als Herausforderung dar, da viele Methoden für den Einsatz an einem Standort konzipiert und daher nur eingeschränkt für die spezifischen Anforderungen der verteilten Anwendung ausgelegt sind (Walter et al. 2016). Methoden können allerdings erst dann ihr volles Potential entfalten, wenn sie an die vorherrschende Entwicklungssituation angepasst werden. Allerdings fehlt zurzeit das Wissens um die entscheidenden Faktoren zur Beschreibung des Entwicklungskontextes in der standortverteilten Produktgenerationsentwicklung, was letztendlich dazu führt, dass Methoden zurzeit nicht bedarfs- und situationsgerecht an die entsprechende standortverteilte Entwicklungssituation angepasst werden können. Grundlegend hierfür ist zusätzlich ein allgemeingültiges Verständnis des Begriffs standortverteilte Produktgenerationsentwicklung. [... aus der Einleitung]

Epiroc Rock Drills AB in Örebro manufactures and develops machinery for the infrastructure required to maintain a fully operational mining industry, such as ventilation, drilling rigs, trucks and loaders etc. In these environmentally conscious times, a large market focus forzero emission machines has begun to emerge. By replacing today'sinternal combustion engines, mining companies can save large sums of money in ventilation costs and fuel while creating a more pleasant working environment in the mines. Due to these rapidly changing needs, Epiroc's machines must also change in design and performance. Epiroc has thus chosen to use interchangeable batteries in their new generation of mining machines. When the battery is discharged, it must be easy to replace with a fullycharged one. From an economic point of view, it is also important that the machine is always in production without any stops, making fast and efficient battery switches desirable. At present, the battery change is usually done with a mono-rail crane down the mine. This has proved to be very difficult and ineffective as the battery is too often jammed into the machine due to the fact that the machine is poorly positioned against the crane. Ceiling heightis also a problem, preferably one should have about 6-7 meters to accomplish a safe lift with the crane, which is not always possible down in a mine. In order to find a more long-term solution to this problem, this degree project took its start. During the course of the process, a number of methods in product development and concept generation have been used to develop different concepts and screen them based on the needs identified at the beginning of the work. The main problem was divided into four sub problems to facilitate conceptgeneration, the most promising sub concepts were visualized using CAD and then put together in different combinations. These combinations were then evaluated against today's solution to easily see what concept should be further developed. This resulted in a concept that consists of a separate platform,which can either be placed on a vehicle or as a stand-alone station. On this platform there are two telescopic arms, one on each side. These arms lifts the three ton heavy battery from the mining machine in an arcuate motion over a charged battery on the platform, placing it in a designated location and then lifts the charged battery into the machine. With this concept, it is also possible to accomplish a safe change with a limited ceiling height of approximately 3.5-4 meters, which is an improvement compared to today's solution.

Full textAbstract:
Le besoin pressant de substitution du plomb dans les alliages de soudure a conduit à une introduction très rapide de nouveaux alliages sans plomb dont la connaissance en termes de comportement n'est pas assez approfondie. En effet, d'autres problématiques sont apparues (l'augmentation de la température du procédé de soudage, trop grand choix disponible dans les alliages alternatifs) alors que les problèmes relatifs aux alliages actuels sont restés sans réponse (le changement incessant de la microstructure des alliages de soudure, la méthodologie empirique prédisant la durée de vie). Tous les paramètres cités ci-dessus modifient la stabilité et la fiabilité des performances spécifiques de l'alliage de soudure et par conséquence, de tout le module électronique.De plus, avec la miniaturisation de l'électronique et les conditions d'environnement de plus en plus sévères, ces obstacles deviennent critiques et les solutions actuelles ne sont plus compatibles. Les demandes de ce marché deviennent donc de plus en plus strictes en termes de prédiction de durée de vie et de contrôle de fiabilité.L'objectif de ce projet est de comprendre et de concevoir une nouvelle formulation d'alliage sans plomb afin de développer une alternative à l'alliage plombé haute température et un alliage pour les applications haute fiabilité et en accord avec les directives gouvernementales. Des approches expérimentales avancées comme la nano-indentation, le suivi de l'évolution de la microstructure par SEM et par EDS mapping, l'étude des effets du vieillissement thermique sur la croissance de la taille des grains avec de la lumière croisée polarisée de microscopie optique etc seront utilisées pour développer un alliage sans plomb qui convienne aux exigences des applications automobile et pipelineThe urgent need for removing lead from solder alloys led to the very fast introduction of lead-free solder alloys without a deep knowledge of their behaviour. As a consequence, additional issues raised (increased thermally induced problems during soldering process, a too wide range of possible available alternative alloy formulations), while problems related to current solder alloys remained unsolved (the constant change of the solder alloy microstructure, empirical predicting lifetime methodology). All the above mentioned issues alter stability and reliability of the application specific performances of the solder alloy, and subsequently of the whole electronic module. These problems become critical and are no longer compatible, as the market goes towards miniaturization and harsh environment conditions. These market trends now require stricter life time prediction and reliability control. Objective of this project is to understand and design a novel lead-free solder formulation to develop a potential alternative to lead-based high temperature melting point solder for high reliability requirements and in accordance with governmental directives. An advanced experimental approach like nanoindentation, microstructure evolution with SEM and EDS mapping, thermal aging effects on continuous grain size growth with cross polarized light of optical microscopy etc. would be implemented to develop doped-SAC lead-free solders for the best-fit to requirements in automotives and pipelines applications

Full textAbstract:
In Sweden, there are students who live in small student apartments. These apartments can be called compact living as a student apartment can be as small as 16 square meters. To take advantage of the place that is in small homes, it would be good if larger furniture could be combined into a piece of furniture. On behalf of Husmuttern AB, this work has been aimed at exploring furniture concepts with sleeping and their functions in a compact living environment for students. The issues being examined are: - What functions are desirable in a multifunctional seating and sleeping furniture for students and people living in compact living environments? - How can a multifunctional seating and sleeping furniture be designed, that is applied to students living in a compact-living environment? Human Centered Design was used as a method and thus a qualitative data collection was carried out in the form of observations. The respondents were in the primary target group and were observed in their everyday lives in their homes. A focus group was involved in generating ideas and concepts. Functional prototypes were built, and 3D models were created in SolidWorks. Digital testing of the concepts was carried out and the development of the Generation Sofa Bed was realized. There is a discussion about how reliable this study is, when the results became situational. However, the respondents were from a limited audience and had different views on what they wanted from a sofa bed, which provided rewarding information for the development of the furniture. The conclusion is that while the Generation Sofa Bed needs to be further developed through testing and evaluation of storage facilities, it has great potential to become a finished product.I Sverige bor det studenter i små studentlägenheter. De lägenheterna kan kallas för compact living då en studentlägenhet kan vara så liten som 16 kvadratmeter. För att ta vara på den plats som finns i små hem vore det bra om större möbler kunde kombineras till en möbel. På uppdrag av Husmuttern AB har detta arbete haft som syfte att utforska möbelkoncept med sov- och sittfunktioner i en compact living miljö för studenter. De frågor som undersöks är: 1. Vilka funktioner är önskvärda i en multifunktionell sitt- och sovmöbel för studenter och personer som bor i compact living miljö? 2. Hur kan en multifunktionell sitt- och sovmöbel konstrueras, som är tillämpad för studenter som bor i compact-living miljö? Human Centered Design användes som metod och därmed genomfördes en kvalitativ datainsamling i form av observationer. Respondenterna var med i den primära målgruppen och observerades i sin vardag i sina hem. En fokusgrupp var med och genererade idéer och koncept. Funktionsprototyper byggdes och 3D modeller skapades i SolidWorks. Digital testning av koncepten genomfördes och utvecklingen av Bäddsoffan Generations blev förverkligad. Det finns en diskussion om hur pålitlig denna studie är, då resultaten blev situationsbaserade. Dock var respondenterna från en begränsad målgrupp och hade olika syn på vad de ville ha av en bäddsoffa, vilket gav givande information till utvecklingen av möbeln. Slutsatsen är att medan Bäddsoffan Generations behöver vidareutvecklas genom testning och utvärdering om förvaringsmöjligheter, så har den stor potential att bli en färdig produkt.

Full textAbstract:
This thesis presents work on a holistic approach for improving the overall design of solar cooling systems driven by solar thermal collectors. Newly developed methods for thermodynamic optimization of hydraulics and control were used to redesign an existing pilot plant. Measurements taken from the newly developed system show an 81% increase of the Solar Cooling Efficiency (SCEth) factor compared to the original pilot system. In addition to the improvements in system design, new efficiency factors for benchmarking solar cooling systems are presented. The Solar Supply Efficiency (SSEth) factor provides a means of quantifying the quality of solar thermal charging systems relative to the usable heat to drive the sorption process. The product of the SSEth with the already established COPth of the chiller, leads to the SCEth factor which, for the first time, provides a clear and concise benchmarking method for the overall design of solar cooling systems. Furthermore, the definition of a coefficient of performance, including irreversibilities from energy conversion (COPcon), enables a direct comparison of compression and sorption chiller technology. This new performance metric is applicable to all low-temperature heat-supply machines for direct comparison of different types or technologies. The achieved findings of this work led to an optimized generic design for solar cooling systems, which was successfully transferred to the market.

Corporations spend a great deal of time and money trying to facilitate innovation in their employees. The act of introducing something new, a product or a service that is viable and innovative is often increased by enhancing or nurturing creativity.This experimental study investigated the effect of group verbally interactive brainstorming (social interaction) on creativity, not by comparing the number of ideas generated on a simple task in a brainstorming session, but by assessing creativity in the final product of a complex heuristic task. The purpose of this study was to compare the effect of group interactive brainstorming to individual brainstorming on individual creativity assessed in the final product.The hypothesis which was tested in this study was that participation in group verbally interactive brainstorming prior to developing a design solution would not facilitate creativity in the final product more than individual brainstorming. Indeed, it was hypothesized that individuals brainstorming in teams.Participants were 36 interior design students in a FIDER accredited program at Virginia Tech. The Multidimensional Stimulus Fluency Measure (MSFM) was administered before beginning the experiment in order to determine individual differences in creativity. Subjects were randomly assigned to either a treatment group than participated in group verbally interactive brainstorming prior to developing a product individually, or a control group that participated in an individual brainstorming session. All subjects then created a design project individually that was assessed for creativity by judges who were recruited from professional interior design organizations. Creativity was measures using the Consensual Assessment for Interior Design Creativity (Barnard, 1992). A post session questionnaire also was used to measure attitudes and perceptions of the subjects about the creative process.Analysis of variance revealed no significant differences when creativity scores were compared between two brainstorming groups. That is, projects developed by interior design students did not differ significantly in creativity systematically between the two brainstorming techniques. When scores on the two dependent variables of secondary interest (novelty and appropriateness) were compared between groups they also did not differ significantly.Responses to post-session questionnaires indicated that although students found it more difficult to generate ideas in a group, they still believed they would generate more ideas and preferred to generate ideas in a group rather than alone. However, when developing a project students preferred to work independently.This study supports past research which suggests that group verbally interactive brainstorming does not enhance creativity. In this study, interactive brainstorming neither enhanced nor constrained creativity in the final product. The creativity scores were higher for those in the individual brainstorming condition, although not significantly so. This study also supports findings which indicate that people still believe they will generate more ideas in a group and that they prefer to generate ideas as a group.Ph. D.

Full textAbstract:
Cette thèse, financée par la DGA, est motivée par la problématique d’évaluation des TRNG pour des applications à très haut niveau de sécurité. Les standards actuels tels que AIS-31 n’étant pas suffisants pour ces types d’applications, la DGA propose une procédure complémentaire, validée sur les TRNG utilisant les oscillateurs en anneau (RO), qui vise à caractériser la source d’aléa des TRNG afin d’identifier les bruits électroniques présents dans celle-ci. Ces bruits se traduisent dans les circuits numériques par le jitter d’horloge générée dans les RO. Ils peuvent être caractérisés par leur densité spectrale de puissance reliée à la variance d’Allan temporelle qui permet, contrairement à la variance standard pourtant encore largement utilisée, de discriminer ces différents types de bruit (thermique, flicker principalement). Cette étude a servi de base à l’estimation de la part du jitter due au bruit thermique utilisé dans les modèles stochastiques décrivant la sortie des TRNG. Afin d’illustrer et de valider l’approche de certification DGA sur d’autres principes de TRNG que les RO, nous proposons une caractérisation de la PLL en tant que source d’aléa. Nous avons modélisé la PLL en termes de fonctions de transfert. Cette modélisation a conduit à l’identification de la source de bruit en sortie de la PLL, ainsi que de sa nature en fonction des paramètres physiques de la PLL. Cela a permis de proposer des recommandations quant au choix des paramètres afin de garantir une entropie maximale. Afin d’aider à la conception de ce type de TRNG, nous proposons également un outil de recherche des paramètres non physiques du générateur assurant le meilleur compromis sécurité/débitThis thesis, funded by the DGA, is motivated by the problem of evaluation of TRNG for applications with a very high level of security. As current standards such as AIS-31 are not sufficient for these types of applications, the DGA proposes a complementary procedure, validated on TRNG using ring oscillators (RO), which aims to characterize the source of randomness of TRNG in order to identify electronic noises present in it. These noises are manifested in the digital circuits by the clock jitter generated in the RO. They can be characterized by their power spectral density related to the time Allan variance which allows, unlike the standard variance which is still widely used, to discriminate these different types of noise (mainly thermal, flicker). This study was used as a basis for estimating the proportion of jitter due to thermal noise used in stochastic models describing the output of TRNG. In order to illustrate and validate the DGA certification approach on other principles of TRNG apart from RO, we propose a characterization of PLL as a source of randomness. We have modeled the PLL in terms of transfer functions. This modeling has led to the identification of the source of noise at the output of the PLL, as well as its nature as a function of the physical parameters of the PLL. This allowed us to propose recommendations on the choice of parameters to ensure maximum entropy. In order to help in the design of this type of TRNG, we also propose a tool to search for the non-physical parameters of the generator ensuring the best compromise between security and throughput

Rapid and efficient life and working styles have become new social structure. With the rise of e-generation, its original subculture now has evolved main culture. Furthermore, information of products within the culture has a strong impact on design ecology. It''s found that e-generation has different attitude toward life, which differs a lot from traditional life models. Since the new phenomena might bring about new concepts, it''s important to provide new strategies for the new phenomena. Moreover, the research is up to provide designers with references through systematic contents and procedures as well as different information of products. AIO Life Mode is applied to this research, which analyzes the e-generation nowadays in Taiwan, and suggests design strategy toward product research and development. By understanding the needs of products and relevant issues among e-generation, it''s expected to get the meanings that the products try to convey, and to work out design strategies in light of e-generation thinking patterns. The results are: 1) E-generation needs professional mobile communication and personalized digital information system to satisfy its work and life. 2) Applying the research of lifestyle to build e-generation''s behavior database and modeling the behavior database is helpful to understand the needs of e-generation toward products. 3) Establishing strategies of product design toward e-generation is important.
