Outcomes of innovative designing are frequently described as enabling us in achieving more desirable futures. How can we design and innovate so as to enable future processes of design and innovation? To investigate this question, this thesis probes the conditions, possibilities and limitations of toolmaking for novelty and knowledge generation, or in other words, it examines designing for designing. The focus of this thesis is on the development of digital design tools that support the reconciliation of conflicting criteria centred on architectural geometry. Of particular interest are the roles of methodological approaches and of biological analogies as guides in toolmaking for design, as well as the possibility of generalising design tools beyond the contexts from which they originate. The presented investigation consists of an applied toolmaking study and a subsequent reflective analysis using second- order cybernetics as a theoretical framework. Observations made during the toolmaking study suggest that biological analogies can, in informal ways, inspire designing, including the designing of design tools. Design tools seem to enable the generation of novelty and knowledge beyond the contexts in and for which they are developed only if their users apply them in ways unanticipated by the toolmaker. Abstract The reflective analysis offers theoretical explanations for these observations based on aspects of second-order cybernetics. These aspects include the modelling of designing as a conversation, different relationships between observers (such as designers) and systems (such as designers engaged in their projects), the distinction between coded and uncoded knowledge, as well as processes underlying the production and the restriction of meaning. Initially aimed at the development of generally applicable, prescriptive digital tools for designing, the presented work results in a personal descriptive model of novelty and knowledge generation in science and design. This shift indicates a perspective change from a positivist to a relativist outlook on designing, which was accomplished over the course of the study. Investigating theory and practice of designing and of science, this study establishes an epistemological model of designing that accommodates and extends a number of theoretical concepts others have previously proposed. According to this model, both design and science generate and encode new knowledge through conversational processes, in which open-minded perception appears to be of greater innovative power than efforts to exercise control. The presented work substantiates and exemplifies radical constructivist theory of knowledge and novelty production, establishes correspondences between systems theory and design research theory and implies that mainstream scientific theories and practices are insufficient to account for and to guide innovation.

Preparing dedicated environments for testing often requires time consuming, manual configurations to be made on databases and the Windows Registry. A proposed Windows application could improve the efficiency and accuracy of such settings by automating the processes and providing a user-friendly graphical user interface. On behalf of Ninetech, a consulting company, such an application was therefore developed - KlarSynt Tools. This application was to enhance the company's previous methods of configuring test environments by removing the need of manual tasks and the use of an unoptimized tool called Verktyg. In the development of the application features such as connecting to servers, retrieving data from databases, and automatic configurations of the Windows Registry was implemented. Problems such as automating manual tasks had to be dealt with for providing accuracy of the configurations. The usage of development patterns such as MVVM was also utilized in the project to provide flexibility in the program code, and in that way prepare the software for future development. Finally, user-friendliness was integrated into the application interface to provide efficiency in the usage of the application. This project resulted in that a Windows application was developed to accurately and efficiently configure settings to a database and the Windows Registry. The developed application showed to significantly reduce the number of steps required and the time taken to perform the configurations in the old process.

Full textAbstract:
In today’s practical reality there are many different tools being used in their respective phases of thesystem development lifecycle. Every tool employs its own underlying metamodel and these metamodelstend to vary greatly in size and complexity, making them difficult to integrate. One solution to overcomethis problem is to build a tool integration framework that is based on a single, shared metamodel.The iFEST project aims to specify and develop such a tool integration framework for tools used in thedevelopment of heterogeneous and multi-core embedded systems. This framework is known as the iFESTTool Integration Framework or iFEST IF.The iFEST IF uses Web services based on the Open Services for Lifecycle Collaboration (OSLC)standards and specifications to make the tools within the tool chain communicate with each other. Tovalidate the framework, an industrial case study called ‘Wind Turbine’, using several embedded systemstools, has been carried out. Tools used to design, implement and test a controller for a wind turbine havebeen integrated in a prototype tool chain. To expose tools’ internal data through Web services, a tooladaptor is needed. This work reports on the development of such a tool adaptor for the RequirementsManagement module of HP Application Lifecycle Management (ALM), one of the tools used in the WindTurbine industrial case study. A generalization of the challenges faced while developing the tool adaptoris made. These challenges indicate that, despite having a tool integration framework, tool integration canstill be a difficult task with many obstacles to overcome. Especially when tools are not developed with tool integration in mind from the start.Idag existerar det en mängd olika verktyg som kan appliceras i respektive fas isystemutvecklings livscykel. Varje verktyg använder sin egna underliggande metamodell. Dessametamodeller kan variera avsevärt i både storlek och komplexitet, vilket gör dem svåra attintegrera. En lösning på detta problem är att bygga ett ramverk för verktygsintegration sombaseras på en enda, gemensam metamodell.iFEST-projektets mål är att specificera och utveckla ett ramverk för verktygsintegration förverktyg som används i utvecklingen av heterogena och multi-core inbyggda system. Dettaramverk benämns iFEST Tool Integration Framework eller iFEST IF.iFEST IF använder webbtjänster baserade på en standard som kallas OSCL, Open Services forLifecycle Collaboration samt specifikationer som gör att verktygen i verktygskedjan kankommunicera med varandra. För att validera ramverket har en fallstudie vid namn ”WindTurbine” gjorts med flertal inbyggda systemverktyg. Verktyg som används för att designa,implementera och testa en styrenhet för vindturbiner har integrerats i prototyp av enverktygskedja. För att bearbeta och behandla intern data genom webbtjänster behövs enverktygsadapter. Detta arbete redogör utvecklingen av en verktygsadapter förkravhanteringsmodulen HP Application Lifecycle Management (ALM), ett av de verktyg somanvänts i fallstudien av vindturbinen. En generalisering av de utmaningar som uppstod underutvecklingen av verktygsadaptern har genomförts. Dessa utmaningar indikerar att, trots att detfinns ett ramverk för verktygsintegration så är verktygsintegration fortfarande vara en svåruppgift att få bukt med. Detta gäller särskilt när verktyg inte är utvecklade med hänsyn tillverktygsintegration från början.

Full textAbstract:
The main objective of the work presented in this thesis is to investigate the two sides of the flute, the face and the heel of a twist drill. The flute face was designed to yield straight diametral lips which could be extended to eliminate the chisel edge, and consequently a single cutting edge will be obtained. Since drill rigidity and space for chip conveyance have to be a compromise a theoretical expression is deduced which enables optimum chip disposal capacity to be described in terms of drill parameters. This expression is used to describe the flute heel side. Another main objective is to study the effect on drill performance of changing the conventional drill flute. Drills were manufactured according to the new flute design. Tests were run in order to compare the performance of a conventional flute drill and non conventional design put forward. The results showed that 50% reduction in thrust force and approximately 18% reduction in torque were attained for the new design. The flank wear was measured at the outer corner and found to be less for the new design drill than for the conventional one in the majority of cases. Hole quality, roundness, size and roughness were also considered as a further aspect of drill performance. Improvement in hole quality is shown to arise under certain cutting conditions. Accordingly it might be possible to use a hole which is produced in one pass of the new drill which previously would have required a drilled and reamed hole. A subsidiary objective is to design the form milling cutter that should be employed for milling the foregoing special flute from drill blank allowing for the interference effect. A mathematical analysis in conjunction with computing technique and computers is used. To control the grinding parameter, a prototype drill grinder was designed and built upon the framework of an existing cincinnati cutter grinder. The design and build of the new grinder is based on a computer aided drill point geometry analysis. In addition to the conical grinding concept, the new grinder is also used to produce spherical point utilizing a computer aided drill point geometry analysis.

This research deals with annotations in scholarly work. Annotations have been studied by many people. A significant amount of research has shown that instead of implementing domain specific annotation applications a better approach is to develop general purpose annotation toolkits that can be used to create domain specific applications. A video annotation toolkit along with toolkits for searching, retrieving, analyzing and presenting videos can help achieve the broader goal of creating integrated work spaces for scholarly work in humanities research similar to existing environments in such fields as mathematics, engineering, statistics, software development and bioinformatics. This research implements a video annotation toolkit and evaluates it by looking at its usefulness in creating applications for different areas. It was found that many areas of study in the arts and sciences can benefit from a video annotation application tailored to their specific needs and that an annotation toolkit can significantly reduce the time for developing such applications. The toolkit was engineered through successive refinements of prototype applications developed for different application areas. The toolkit design was also guided by a set of features identified by the research community for an ideal general purpose annotation toolkit. This research contributes by combining these two different approaches to toolkit design and construction into a hybrid approach. This approach could be useful for similar or related efforts.

Full textAbstract:
This PhD thesis is based on six articles and proposes new approaches for modelling of the life of cutting tools and for determining the optimal tool replacement time. These issues are very closely related and play a critical role in machining economics. Replacing a tool too early means wasting of its potential and leads to high costs and reduced productivity. Late replacement poses a risk of wear-out and other types of tool failures, which can damage the component being produced and can cause expensive equipment downtimes. Therefore a lot of work has been done to develop models for predicting the life of a tool and to optimize its replacement time. Probably the best known of them is the Taylor’s tool life equation. Developed in 1906 Taylor’s equation expresses the tool life in terms of the cutting speed. Despite being over a century old, this model is still widely used in practice. However, Taylor’s equation has a few drawbacks. For example, it ignores the effect of other, though less important, process parameters such as the depth of cut and the feed. To walk around this issue several extensions of Taylor’s equation have been proposed and are discussed in this thesis. Nevertheless all these models share another common flaw. They assume that tool life is deterministic, i.e., that given the process parameters the exact time to wear-out can be calculated. Unfortunately, in real machining processes there are a lot of sources of variation that affect the rate of tool wear and influence its life. As a result, deterministic models rarely give accurate estimates and are only valid as approximations. To improve tool life predictions and assist process planners in choosing the optimal replacement time this PhD thesis proposes new methods. The underlying assumption is that tool life is a stochastic quantity and follows a certain probability distribution. With this in mind the reliability function is derived. Based on the physical analysis of machining processes it is assumed that a tool can fail due to the three main causes: (i) wear, (ii) internal defects and (iii) external stresses. Tool wear depends on a number of factors, including the characteristics of the tool itself, such as its material, geometry and coating, properties of the workpiece material, cutting parameters, rigidity of the machine tool and the efficiency of the cooling process. This last factor is particularly important as most of the tool wear mechanisms depend on temperature. Therefore in this PhD thesis a lot of attention is given to high pressure cooling, which is an effective way to reduce the temperature in the cutting zone. Internal defects are micro voids and cracks that develop inside the tool material during its manufacturing process or as a result of inappropriate handling. They act as stress concentrators and lead to shorter than normal tool life. External stresses are severe overloads that cause immediate tool failure regardless of its quality. They are random in nature and may originate from machine operator errors, failure of supporting equipment or some other external sources. Considering all three failure modes total tool reliability function is found. It is assumed that in a given batch a certain percentage of tools are “bad”, i.e., they contain internal defects, while the rest are “good”. The life of the normal tools is modelled by a two-parameter Weibull distribution. Failures due to internal defects are also accounted for by the Weibull distribution, but with different parameters. Then the life of a tool chosen at random is predicted by the mixture model. In addition, tools of both types can fail due to external stresses, the occurrence of which is model by a homogeneous Poisson process. The derived tool reliability function is used to determine the replacement time. Two models are proposed for this purpose. The first one is called the minimum acceptable reliability approach. The idea is to select such a replacement period that the reliability of the tool during it would not fall below a certain minimum level. We show that, when the reliability function is known, this can be done by using a simple graphical procedure. The second model is based on the age replacement policy, which attempts to balance the costs of preventive and failure provoked tool changes. To solve this optimization problem the total time on test (TTT) transform of the reliability function is introduced, and a method for estimating it form the experimental data is proposed. Then, as in case of the first model, the replacement time is found by employing a simple graphical procedure. For the above approach to be used in practice the expected costs of preventive and failure provoked replacements need to be known. It is shown that the former one can be determined by applying traditional formulas found in machining economics handbooks. The penalty cost, on the other hand, is not so well defined, and no good estimation models are available. Therefore, a new, probability tree-based approach is developed in this thesis. The relevance and the applicability of the proposed models is tested in a few experimental and case studies described in the appended articles. In Article 1 reliability of machining systems as a whole is investigated, and the stochastic nature of the processes involved is clearly shown. In Article 2 it is demonstrated that a two-parameter Weibull distribution can be used to model the tool life, and a simple replacement model based on the reliability function is proposed. In Article 3 a more generic tool life model is developed, but a two-parameter Weibull distribution is still found to be a good approximation. The replacement time is than found by employing an optimization procedure based on the age replacement policy. In Article 4 an approach for estimating the penalty cost, which is a key input to the age replacement model, is developed. Finally in Articles 5 and 6 it is shown that high pressure cooling can help to extend the tool life and possibly to reduce its variation, which is the main reason why probabilistic models are needed. Based on this experimental work and case studies the thesis concludes that stochastic approaches for tool life modelling and for determination of replacement time are relevant and applicable in practice. Therefore further work needs to be done to extend the use of these methods beyond the set-ups and conditions tested throughout the research described in this PhD thesis.

En aquesta tesi interdisciplinar desenvolupem eines algebraiques per a problemes en filogenètica i genòmica.
Per estudiar l'evolució molecular de les espècies sovint s'usen models evolutius estocàstics. L'evolució es representa en un arbre (anomenat filogenètic) on les espècies actuals corresponen a fulles de l'arbre i els nodes interiors corresponen a ancestres comuns a elles. La longitud d'una branca de l'arbre representa la quantitat de mutacions que han ocorregut entre les dues espècies adjacents a la branca. Llavors l'evolució de seqüències d'ADN en aquestes espècies es modelitza amb un procés Markov ocult al llarg de l'arbre. Si el procés de Markov se suposa a temps continu, normalment s'assumeix que també és homogeni i, en tal cas, els paràmetres del model són les entrades d'una raó de mutació instantània i les longituds de les branques. Si el procés de Markov és a temps discret, llavors els paràmetres del model són les probabilitats condicionades de substitució de nucleòtids al llarg de l'arbre i no hi ha cap hipòtesi d'homogeneïtat. Aquests últims són els tipus de models que considerem en aquesta tesi i són, per tant, més generals que els de temps continu.
Des d'aquesta perspectiva s'estudien els problemes més bàsics de la filogenètica: donat un conjunt de seqüències d'ADN, com decidim quin és el model evolutiu més adequat? com inferim de forma eficient els paràmetres del model? I fins i tot, tal i com també hem provat en aquesta tesi, és possible que les espècies no hagin evolucionat seguint un sol arbre sinó una mescla d'arbres i llavors cal abordar aquestes preguntes en aquest cas més general. Per a models evolutius a temps continu i homogenis, s'ha proposat solucions diverses a aquestes preguntes al llarg de les últimes dècades. En aquesta tesi resolem aquests dos problemes per a models evolutius a temps discret usant tècniques algebraiques provinents d'àlgebra lineal, teoria de grups, geometria algebraica i estadística algebraica. A més a més, la nostra solució per al primer problema és vàlida també per a mescles filogenètiques.
Hem fet tests dels mètodes proposats en aquesta tesi sobre dades simulades i dades reals del projectes ENCODE (Encyclopedia Of DNA Elements). Per tal de provar els nostres mètodes hem donat algoritmes per a generar seqüències evolucionant sota un model a temps discret amb un nombre esperat de mutacions prefixat. I així mateix, hem demostrat que aquests algorismes generen totes les seqüències possibles (per la majoria de models). Els tests sobre dades simulades mostren que els mètodes proposats són molt acurats i els resultats sobre dades reals permeten corroborar hipòtesis prèviament formulades. Tots els mètodes proposats en aquesta tesi han estat implementats per a un nombre arbitrari d'espècies i estan disponibles públicament.In this thesis we develop interdisciplinary algebraic tools for genomic and phylogenetic problems. To study the molecular evolution of species one often uses stochastic evolutionary models. The evolution is represented in a tree (called phylogenetic tree) whose leaves represent current species and whose internal nodes correspond to their common ancestors. The length of a branch of the tree represents the number of mutations that have occurred between the two species adjacent to the branch. Then ,the evolution of DNA sequences in these species is modeled with a hidden Markov process along the tree. If the Markov process is assumed to be continuous in time, it is usually assumed homogeneous as well and, if so, the model parameters are the instantaneous rate of mutation and the lengths of the branches. If the Markov process is discrete in time, then the model parameters are the conditional probabilities of nucleotide substitution along the tree and there is no assumption of homogeneity. The latter are the types of models we consider in this thesis and are therefore more general than the homogeneous continuous ones. From this perspective we study the basic problems of phylogenetics: Given a set of DNA sequences, what is the evolutionary model that best fits the data? how can we efficiently infer the model parameters? Also, as we also checked in this thesis, it is possible that species have not evolved along a single tree but a mixture of trees so that we need to address these questions in this more general case. For continuous-time, homogeneous, evolutionary models, several solutions to these questions have been proposed during the last decades. In this thesis we solve these two problems for discrete-time evolutionary models, using algebraic techniques from linear algebra, group theory, algebraic geometry and algebraic statistics. In addition, our solution to the first problem is also valid for phylogenetic mixtures. We have made tests of the methods proposed in this thesis on simulated and real data from ENCODE Project (Encyclopedia Of DNA Elements). To test our methods, we also provide algorithms to generate sequences evolving under discrete-time models with a given expected number of mutations. Even more, we have proved that these algorithms generate all possible sequences (for most models). Tests on simulated data show that the methods are very accurate and our results on real data confirm hypotheses previously formulated. All the methods in this thesis have been implemented for an arbitrary number of species and are publicly available.

A primary challenge in embryology is to understand the factors that govern the development of preimplantation (PI) embryos and how these factors relate to embryo viability in the field of in vitro fertilization (IVF). This is particularly important as clinical policy moving towards single embryo transfer (SET) has gained awareness to manage unprecedented numbers of multiple births, such as twins and triplets, resulting from artificial reproductive techniques. Conditions that correlate with developmental potential of candidate embryos are disputed in the field, however, as the requisite data is difficult to obtain.The metabolic profiles of embryos during in vitro culture have been suggested as a key indicator of developmental potential, and approaches have been clinically implemented to select transfer candidates which make the most efficient use of nutrients. Existing microdroplet analysis techniques are accurate and suitable for non-invasive assessment of single embryos. Unfortunately, the process of determining metabolite levels in nanoliters of culture media through fluorometric assays is low-throughput and requires specialized expertise, hindering widespread clinical use of these methods. The goal of this thesis is to develop microfluidics-based approaches for improving metabolic analysis of PI embryos and mammalian cells. This challenge necessitates two competencies: methods for automating chemical assays and methods for supporting cell cultures, which can be integrated with analysis. Contributions include a standalone platform for determining the metabolite use of single embryos. Profiles may be acquired automatically, which reduces significant technician hours and improves repeatability. Techniques are developed for performing embryo culture in the smallest culture volumes to date in microfabricated environments. Microfluidic approaches have enabled culture that outperforms the current state of art approach based on cell count measurements.
(cont.) An integrated system is introduced, merging analysis and culture competencies to perform metabolic profiling of separate cultures of mammalian cells in parallel. Finally, new paradigms in microfluidic design are presented based on the concept of vertically integrated architectures, suitable for overcoming density limitations of microfluidic assays. A scalable analysis platform for refining embryo selection has been long warranted and would enable pursuit of the difficult questions relating metabolism and embryo viability as the clinical movement towards SET continues.

SpecTRM is a CAD system for digital automation. The intent of SpecTRM is to assist engineers in managing the requirements, design and evolution process aspects of developing software. The purpose of this thesis project is to extend SpecTRM even further through the development of visualization tools. This will consist of building tools in three general areas to increase the functionality of SpecTRM. These areas include post-simulation visualization tools, interactive visualizations and 3D visualizations. Post-simulation visualization involves taking the data produced by a SpecTRM model's simulation of a system and constructing tools that allow the user to see the data in a more meaningful way. Run-time interactive tools involve providing tools that help the user interact with and control the system during simulator operation. 3D visualizations provide a means for the user to see the output of the simulation transform 3D models. The goal of this thesis is to develop meaningful ways to understand and manage a complex software system in addition to all the tools that SpecTRM provides.

This paper describes the format of monitoring data files that are collected for external measuring sites and at laboratory experiments at the Institute for Building Climatology (IBK). The Monitoring Data Files are containers for storing time series or event driven data collected as input for transient heat and moisture transport simulations. Further applications are the documentation of real world behaviour, laboratory experiments or the collection of validation data sets for simulation results ( whole building / energy consumption / HAM ). The article also discusses the application interface towards measurement data verification tools as well as data storage solutions that can be used to archive measurement data files conveniently and efficiently.

Full textAbstract:
Considering the lack of clear guidance regarding the way business could include social sustainability into their operations, the objective of this research project was to study the functionality of social sustainability tools which are used worldwide by business practitioners and assess how useful these tools are to overcome barriers related with social aspects of sustainability as they are described in the Framework for Strategic Sustainable Development (FSSD): health, influence, competence, impartiality and meaning-making. A qualitative method analysis was selected, based upon direct content analysis. Elements from the 5 Level Framework (5LF) and the FSSD were used for designing two review processes to analyse selected social sustainability tools. The 5LF is useful for planning in complex systems, while the FSSD is designed to address complex challenges and recognize opportunities which aim to sustainability. The findings from the research show which tools, based on their functionality, can help a company move towards sustainability and illustrate how they address different social sustainability aspects. Based on these findings, recommendations were developed which included key features of the selected social sustainability tools. These recommendations could help business practitioners to choose the most appropriate tool for specific business context depending on the company’s needs.

Tools that perform semi-automated refactoring are currently under-utilized by programmers. If more programmers adopted refactoring tools, software projects could make enormous productivity gains. However, as more advanced refactoring tools are designed, a great chasm widens between how the tools must be used and how programmers want to use them. This dissertation begins to bridge this chasm by exposing usability guidelines to direct the design of the next generation of programmer-friendly refactoring tools, so that refactoring tools fit the way programmers behave, not vice-versa.

In dieser Arbeit entwickeln wir Rechenwerkzeuge zur Berechnung von Baum– und Einschleifensuperstringamplituden. Insbesondere stellen wir eine rekursive Methode zur Konstruktion kinematischer Faktoren für die Amplitude offener Superstrings auf Baumniveau bereit und präsentieren systematischeWerkzeuge, um die supersymmetrischen Auslöschungen in n-Boson- Zwei-Fermion Amplituden auf Einschleifenniveau des RNS Superstrings zu manifestieren.
Für offene Superstringamplituden auf Baumniveau stellen wir vereinfachte Rekursionen für Mehrteilchensuperfelder vor, mit denen kinematische Teile von offenen Superstringamplituden auf Baumniveau konstruiert werden können. Wir diskutieren auch die Eichtransformationen, die ihre Lie-Symmetrien erzwingen, wie dies durch die Bern-Carrasco-Johansson-Dualität zwischen Farbe und Kinematik nahegelegt wird. Eine weitere Eichtransformation aufgrund von Harnad und Shnider soll die Theta-Expansion von Mehrteilchensuperfeldern vereinfachen und die Notwendigkeit umgehen, ihre Rekursionsrelationen über die niedrigsten Komponenten hinaus zu verwenden. Die Ergebnisse dieser Arbeit vereinfachen die Komponentenextraktion aus kinematischen Faktoren im reinen Spinor Superspace erheblich.
Wir untersuchen dann masselose n-Punkt-Ein-Schleifen-Amplituden des offenen RNS Superstrings mit zwei externen Fermionen und bestimmen ihre Weltflächen-Integranden. Die beitragenden Korrelationsfunktionen, an denen Spin-1/2– und Spin-3/2-Operatoren aus den Fermionen-Vertices beteiligt sind, werden zu einer beliebigen Multiplizität ausgewertet. Darüber hinaus führen wir Techniken ein, um diese Korrelatoren über die Spinstrukturen derWeltflächen- Fermionen zu summieren, um alle Auslöschungen aufgrund der Supersymmetrie der Raumzeit zu manifestieren. Diese spinsummierten Korrelatoren können in Form von doppeltperiodischen Funktionen ausgedrückt werden, die aus der mathematischen Literatur über elliptische Multiple-Zeta-Werte bekannt sind. Unsere spinsummierten Korrelatoren an der Grenze des Modulraums sind auf kompakte Darstellungen von fermionischen Ein-Schleifen-Integranden für ambitwistorische Strings spezialisiert.In this thesis, we develop computational tools to calculate tree and one-loop superstring amplitudes. In particular, we provide a recursive method to construct kinematic factors of tree level open superstring amplitudes and present systematic tools to manifest the supersymmetric cancellations in n-boson-two-fermion amplitudes at the one-loop order of the RNS superstring. For tree level open superstring amplitudes, we present simplified recursions for multiparticle superfields, which can be applied to construct kinematic parts of open superstring amplitudes at tree level. We also discuss the gauge transformations which enforce their Lie symmetries as suggested by the Bern-Carrasco-Johansson duality between color and kinematics. Another gauge transformation due to Harnad and Shnider is shown to streamline the theta-expansion of multiparticle superfields, bypassing the need to use their recursion relations beyond the lowest components. The findings of this work greatly simplify the component extraction from kinematic factors in pure spinor superspace. We then investigate massless n-point one-loop amplitudes of the open RNS superstring with two external fermions and determine their world-sheet integrands. The contributing correlation functions involving spin-1/2 and spin-3/2 operators from the fermion vertices are evaluated to any multiplicity. Moreover, we introduce techniques to sum these correlators over the spin structures of the world-sheet fermions, such as to manifest all cancellations due to spacetime supersymmetry. These spin-summed correlators can be expressed in terms of doubly-periodic functions known from the mathematics literature on elliptic multiple zeta values. On the boundary of moduli space, our spin-summed correlators specialize to compact representations of fermionic one-loop integrands for ambitwistor strings.

Full textAbstract:
Digital image processing is a vast field of applied mathematics that covers those processes whose inputs and outputs are images and those that extract attributes and patterns from images. In my thesis two different subcategories of digital image processing are investigated: pattern recognition and feature extraction, in particular the recognition of algebraic curves in images and edge detection techniques, and image compression, with particular attention to map-aided techniques.
Patter recognition is the study of semi-automated and automated methods for the recognition of pattern and regularities in data. In the first part of my thesis, I present a novel method for the recognition of curvilinear profiles in digital images. The proposed method, semi-automatic for both closed and open planar profiles, is essentially based on a piecewise application of the Hough transform technique.
The Hough transform is a known technique used in image analysis and digital image processing to recognize shapes in images. One of the drawbacks of this technique is the need to identify a potentially approximating family of curves before the recognition algorithm can be successfully applied. Thus, we developed an innovative procedure for the recognition of both closed and open curvilinear profiles in 2D digital images, without knowing neither a family of predefined curves nor a predefined look-up table of a prototypal shape. Our method provides a G1 continuous spline curve – eventually containing C0 junctions where cusps occur – which approximates the sought profile.
Edge detection is a widely used tool in image processing with the aim of identifying abrupt changes or discontinuities in a digital image. In the second part of my thesis, I present two original edge detection methods, based on Radial Basis Functions interpolation.
For the detection of jump discontinuities in 1D problems, we developed an iterative method based on interpolation with Variably Scaled Kernels (VSKs). This is shown to outperform an existing iterative edge detection method based on multiquadric radial basis function interpolation. To extend our purely one-dimensional edge detector to any dimension, we then introduce an innovative non iterative technique that detects edges by identifying the local maxima of the normalized absolute values of the RBF interpolant coefficients. The RBF interpolant is built-upon the compactly supported C2 Wendland function and exploits its advantageous properties to provide a robust and low-cost method. Numerical examples in 1D and 2D are included to illustrate its effectiveness and efficiency.
Image compression is a specific type of data compression with the aim of reducing the amount of data necessary for image storage and transmission. Image compression has an increasingly important role in diverse applications, such as remote sensing, videoconferencing, medical imaging and many more.
One of the classical approaches to image compression are multi-scale wavelet based methods. They do not always lead to fully satisfactory results as they do not adapt to the local structure of images, such as edges. Techniques to solve this drawback have been developed in recent works. Because of the need to locally adapt the compression methods to the geometry of image, feature extraction plays a significant role also in this case. In the last part of thesis, I present two original multi-scale image compression algorithms that are map-aided, to ensure a better faithfulness of the reconstruction to the original image. These methods use a prediction step with a multiquadric radial basis function interpolant and WENO scheme to determine the shape parameter. For the first method an edge detection procedure is applied to the original image, from this we obtain an edge map that determines the local prediction step. For the second method, instead, we compute different local reconstructions and we use a map to save the best one.Digital image processing is a vast field of applied mathematics that covers those processes whose inputs and outputs are images and those that extract attributes and patterns from images.

Traditionell undervisning har fungerat på ett visst sätt i väldigt lång tid - tills nyligen. Digitala läromedel - DLTs (Digital Learning Tools) - har utvecklats och testats i en stor mängd skolor i hela världen, speciellt för ämnena inom naturvetenskap. Detta projektet handlar om hur DLTs för matematik bör bli utvecklade för att tillhandahålla ett så komplett lärande som möjligt. Tidigare forskning har visat vikten av att träna lärarna hur de ska använda DLTs i undervisningen samt att DLTs ger bättre resultat när de används som ett komplement till den vanliga undervisningen istället för att ersätta moment i den. Slutsatsen i detta arbete är att DLTs fortfarande ska användas som komplement, att lärares roll är väldigt viktig och att DLTs måste kunna anpassa sig till individer med olika behov.Traditional education has looked the same for a very long time - until recently. Digital learning tools - DLTs - have been developed and tested in numerous educational environments around the world, specifically for the science subjects. This project was about how DLTs for mathematics should be developed in order to provide an as complete learning experience as possible. Earlier research has shown the importance of teacher training, as well as the fact that better learning outcomes are achieved when DLTs are used as a supplement to traditional education rather than a substitute. The conclusion in this research is that DLTs still have to be used as a supplement, that the teachers role is of very high importance, and that DLTs have to be able to adapt to individual users with specific needs.

This paper contains an evaluation of common open source static analysistools available for C. The tools algorithms are examined and measured in a test environment designed for such benchmarks to present their strengths and weaknesses. The examined tools represent different approaches to static analysis to get a good coverage of the algorithms that are commonly used. The test environment shows how many bugs that are correctly reportedby the tools, and also how many falsely reported bug they produce. The revealed strengths and weaknesses are discussed in relation to the tools algorithms to gain a deeper understanding of their limitations.

The aim of this thesis is to provide academic support to the oldest discipline of Mechanical Engineering, namely "Machine Design".
The rapid pace of technological development drives every individual, especially students. The industrial revolution in the first half of the 19th century contributed greatly to the advancement of Mechanical Engineering. The theories and experimental data from that time, some developed almost a hundred years ago are still in use in the original form while others have evolved to keep up with the times.
This thesis attempts to bring some of that classical machine design theory into a modern user-friendly form that is portable across the Internet.
Here the user will be presented with an interactive menu of topics of Machine Design where each is split sub-categorically as Theory and Application.
According to the choice made, short excerpts of theory are presented on the chosen matter. The theory will include but not be limited to the important relationships relevant to the design of the particular machine element.
After the review of the Theory, the user will be able to navigate to the application where the relationships from the theory will be awaiting user input in the form of solvers.
Since the primary emphasis of the thesis is about cultivating knowledge of the underlying theory, the applications will not be self-correcting or self-assuming.
The user will need to understand the relationships sufficiently well prior to using the applications to solve homework or design assignments.
The created Toolbox is available to all registered users through a login access. The user can then choose to review theory or directly access the applications of the described theory.
The thesis successfully demonstrates the use of the Internet as the media for education.Master of Science

La predicció és un concepte de recerca molt interessant. No es només predir el resultat futur, sinó que també cal predir el resultat conegut, a vegades anomenat validació. L'aplicació de tècniques de predicció sobre el comportament de sistemes és sempre molt útil perquè ens ajuda a comprendre el funcionament del elements que estem analitzant.
Aquest treball va començar tot analitzant la influència de l'execució concurrent de diverses aplicacions de pas de missatges. Així, l'objectiu original era trobar i proposar uns algorismes de planificació de processos que obtinguessin un throughput màxim, equitatiu, i amb un rendiment adecuat del sistema.
Per a poder avaluar adecuadament aquestes polítiques de planificació, varem trobar que ens calien eines d'analisi. Dimemas i Paraver són les eines de l'entorn que anomenem DiP. Tot i que aqueste eines varem estar dissenyades fa més de deu anys, són vàlides i ampliables.
Dimemas es l'eina de predicció de rendiment. Tot fent ús de models senzills, pot predir el temps d'execució de les aplicacions de pas de missatges, fent servir un conjunt de paràmetres que modelitzen el funcionament del sistema. No és només una eina que prediu el temps d'execució, sinó que s'ha demostrat molt útil per entendre la influència dels diferents paràmetres del sistema en el temps de resposta de les aplicacions
L'eina d'anàlisi de l'entorn DiP s'anomena Paraver. Permet analitzar simultàniament moltes aplicacions i el sistema des de diferent punts de vista: analitzant els missatges, les contencions a la xarxa de comunicació, la planificació del processador.
Promenvir/ST-ORM és l'eina d'anàlisi estocàstic. Inclou utilitats que permeten analitzar la influència de qualsevol paràmetre del sistema, així com sintonitzar els paràmetres de simulació, per aconseguir que les prediccions s'aproximin a la realitat.
La qualitat i categoria de les decisions que varem prendre fa anys queda demostrada per la mètode de com cal utilitzar conjuntament totes les eines, i perquè són eines què es corresponen a l'estat de l'art actual.
Aquest treball inclou la descripció de les diferents eines, des de el punt de vista de disseny fins la seva utilització (en cert grau), la validació de Dimemas, el disseny conceptual de Promenvir, la presentació del mètode que cal emprar amb aquestes eines (incloent anàlisi d'aplicacions individuals fins a anàlisis més complex), i alguns dels nostres primers anàlisi sobre polítiques de planificació de processador.
Prediction is an interesting research topic. It is not only to predict the future result, but also to predict the past, often called validation. Applying prediction techniques to observed system behavior has always been extremely useful to understand the internals of the elements under analysis.
We have started this work to analyze the influence of several message passing application when running in parallel. The original objective was to find and propose a process scheduling algorithm that maximizes the system throughput, fair, proper system utilization.
In order to evaluate properly the different schedulers, it is necessary to use some tools. Dimemas and Paraver, conform the core of DiP environment. These tools has been designed ten years ago, but still valid and extensible.
Dimemas is a performance prediction tool. Using a single models, it capable to predict execution time for message passing applications, considering few system parameters for the system. It is useful not only to predict the result of an execution, but to understand the influence of the system parameters in the execution time of the application.
Paraver is the analysis tool of DiP environment. It allows the analysis of applications and system from several points of view: analyzing messages, contention in the interconnection network, processor scheduling.
Promenvir/ST-ORM is a stochastic analysis tool. It incorporates facilities to analyze the influence of any parameter in the system, as well as to tune the simulation parameters, so the prediction is close to reality.
The methodology on how to use these tools as a group to analyze the whole environment, and the fact that all those tools are State of the Art, demonstrates the quality of the decisions we made some years ago.
This work includes description of the different tools, from its internal design to some external utilization, the validation of Dimemas, the concept design of Promenvir, the architecture for Promenvir, the presentation of the methodology used with these tools (for simple application analysis to complex system analysis), and some of our first analyses on processor scheduling policies.

Scheduling problems consist in determining how to execute the activities of a project in order to satisfy some requirements. Such problems are ubiquitous nowadays in industry and services, but finding solutions of scheduling problems is computationally hard. The main contribution of this thesis is the presentation of efficient SAT and SMT-based methods to solve scheduling problems. More precisely we tackle the well-known problem RCPSP as well as many extensions of it. The most challenging constraints in RCPSP-based problems are resource constraints, which specify that activities must share a set of finite resources. To handle such constraints we provide efficient SAT encodings of pseudo-Boolean (PB) constraints, which take into account the existence of collateral constraints. The provided PB encodings can have application to combinatorial problems in general, not only scheduling. The systems that we present are state-of-the-art in exact scheduling solving.Un problema de scheduling consisteix en decidir com executar les activitats d'un projecte per tal de satisfer un seguit de requeriments. Aquests problemes són molt presents en els sectors de la industria i els serveis, però trobar una solució d'un problema de scheduling és computacionalment costós.

Concretament ataquem el conegut problema RCPSP i diverses extensions d'aquest. Les restriccions més complexes en aquests problemes són les d'ús de recursos finits compartits entre activitats. Per tal de tractar aquestes restriccions, proporcionem codificacions eficients a SAT de restriccions pseudo-Booleanes (PB), que tenen en compte l'existència de restriccions col·laterals. Les codificacions de PB proposades són de propòsit general i poden tenir aplicació a tot tipus de problemes combinatoris.

software product line is a set of software-intensive systems that share a common, managed set of features satisfying the specificneeds of a particular market segment or mission. The main attractive part of SPL is developing a set of common assets which includes requirements, design, test plans, test cases, reusable software components and other artifacts. Tools for the development of softwareproduct line are very few in number. The purpose of these tools is to support the creation, maintenance and using different versions ofproduct line artifacts. This requires a development environment that supports the management of assets and product development,processes and sharing of assets among different products.
The objective of this master thesis is to investigate the available tools which support Software Product Line process and itsdevelopment phases. The work is carried out in two steps, in the first step available Software Product Line tools are explored and a list of tools is prepared, managed and a brief introduction of each tool is presented. The tools are classified into different categoriesaccording to their usage, relation between the tools is established for better organization and understanding. In the second step, two tools Pure::variant and MetaEdit+ are selected and the quality factors such as Usability, Performance, Reliability, MemoryConsumption and Capacity are evaluated.
