Detta examensarbete är en del av ett större projekt (Evochip) som bedrivs på Lunds tekniska högskola, avdelningen för industriell produktion (iProd) och med samarbete med bland annat AB Markaryds metallarmatur och Mistra innovation. I detta arbete har en dynamisk kostnadsmodell tagits fram för att beräkna tillverkningskostnaderna av komponenter tillverkade av återanvända spånor av blyfri mässing från de egna tillverkningsprocesserna hos AB Markaryds metallarmatur (MMA). Idag skickas alla kasserade detaljer och materialspill ner till materialleverantörer i Sydeuropa för återvinning. Transporterna sker med lastbil och återvinningsprocessen utgår från ett energikrävande nedsmältningssteg. Idag pågår utvecklingsprojekt med målet att återanvända spånorna utan nedsmältning hos MMA, men kostnadsbilden per detalj har varit hittills okänd. Med hjälp av detta examensarbete ska detaljpriset tas fram. Tillverkningsprocessen delas in i totalt 11 olika förädlingsstationer. För att kartlägga kostnaderna används Jan-Eric Ståhls dynamiska kostnadsmodell. Nödvändig data och information har samlats in med hjälp av intervjuer på företaget och genom företagets egna dokumentationer. För att minska felmarginalen i resultaten har lämpliga Monte Carlo simuleringar utförts. Arbetet utgår även från ett hållbarhetsperspektiv. Förutom elimineringen av lastbilstransporter och energikrävande nedsmältningsprocesser för grundmaterialet, främjar arbetet även användning och återanvändning av blyfri mässing genom att kompaktera spånor till nya grönkroppar. Detta då forskare länge har varnat för blyade detaljers negativa hälsoeffekter. Detaljen som undersöks i detta arbete är en ventil som har benämningen EVO 10, vilken återfinns i företagets blyfria standardsortiment. Kostnadsmodellen är dynamisk till den grad att den i framtiden skulle kunna appliceras på övriga blyfria mässingkomponenter hos MMA. En jämförelse mellan två olika koncept presenteras i resultatdelen. Koncept ett representerar dagens tillverkningssystem, och koncept två framtidens kompakteringsteknik. Då många av förädlingsstegen är desamma för båda systemen, valdes en jämförelse mellan framtagningen av grönkropparna genom de två olika koncepten. Resultaten visar att kutsar, framtagna enligt dagens tillverkningssystem, kostar 12,75 SEK/detalj, och kutsar framtagna enligt koncept två kostar 9,61 SEK/detalj. Då koncept två är beroende av spånor från dagens tillverkningssystem, kan MMA inte helt gå över till att kompaktera spånor till nya kutsar. Mer arbete måste utföras för att hitta en balanserad modell mellan de två olika tillverkningssystemen för bästa möjliga resultat. Monte Carlo-simuleringarna visar att kostnaden per detalj uppgår till 12.96 SEK, detta med de på förhand valda konstanter och variabler i systemet.This master thesis is part of a larger project (Evochip), conducted at Lund University, faculty of engineering, Industrial Production Department (iProd). The project is in collaboration with AB Markaryds metallarmatur and Mistra innovation. In this work, a dynamic cost model has been developed to calculate the manufacturing costs of components made from recycled chips of lead-free brass from the manufacturing processes of AB Markaryds metallarmatur (MMA). In the current situation, all rejected details and waste materials are sent to the material supplier in southern Europe for recycling. The transport takes place by trucks and the recycling process is based on an energy-intensive melting step. Development projects are currently underway to reuse the chips without melting at sight at MMA´s facilities, but the cost per detail has been unknown for the company. With the help of this thesis, the manufacturing price will be presented. The manufacturing process is divided into a total of 11 different processing stations. To estimate the costs, Jan-Eric Ståhl's dynamic cost model is used. Necessary data and information have been collected using interviews with the employees of the company and through the company's own documentation regarding the production lines. In order to reduce the error margin in the results, suitable Monte Carlo simulations have been performed. The work is also based on a sustainability perspective. In addition to eliminating transportations by trucks and energy-intensive melting processes for the products, the work also promotes the use and reuse of lead-free brass by pressing metal chips to form new bars. All this in order to avoid leaded brass components due to the negative health effects caused by the lead. The component investigated in this work is a radiator valve called EVO 10. The valve is found in the company's lead-free standard range. The cost model in this project is dynamic to the extent that it could be applied in the future to other lead-free brass components at MMA. A comparison of two different concepts is presented in the results section. Concept one represents the current manufacturing system, and concept two, the future compacting technology. Since many of the processing steps are the same for both systems, a comparison was made between the productions of the pellet through the two different concepts. The results show that pellets made according to today's manufacturing system cost 12.75 SEK / detail, and pellets manufactured according to concept two costs 9.61 SEK / detail. As concept two is dependent on chips from today's manufacturing system, MMA cannot completely switch to compacting chips to new pellets. More work must be done to find a balanced model between the two different manufacturing systems for the best possible results.The results from the Monte Carlo-simulations shows that the manufacturing cost with the chosen parameters and variables is 12.96 SEK/detail.

O reúso de software enfrenta inúmeras barreiras gerenciais, técnicas e culturais na sua adoção, e a definição da estrutura de ativos reutilizáveis de software é uma dessas barreiras técnicas. Para solucionar isso, o Reusable Asset Specification (RAS) é um padrão de facto proposto pela OMG. Uma especificação como o RAS define e padroniza um modelo de ativos (assets) reutilizáveis, e é a base para a construção e para o uso de um repositório de ativos que apoia a reutilização de software. No entanto, para ser adotado na prática, o RAS necessita resolver suas lacunas através da sua extensão e da definição de informações complementares. Essas lacunas estão detalhadas neste trabalho. Solucionando estas lacunas, o RAS torna-se útil para auxiliar efetivamente na padronização do empacotamento dos ativos reutilizáveis e para guiar a estrutura do repositório de reutilização de software. Alguns trabalhos anteriores já responderam parcialmente essa questão, porém eles atendiam propósitos muito específicos, não possuíam uma ferramenta de apoio ou não haviam sido avaliados em contexto real de (re)uso. Esse trabalho propõe o Software Profile RAS (SW-RAS), uma extensão do Profile de componentes do RAS, que propõe soluções para diversas de suas lacunas, incluindo informações úteis e artefatos relevantes apontados na literatura, baseados em outros modelos de ativos reutilizáveis, em outras extensões do RAS e na experiência do processo de reúso no desenvolvimento de software. Particularmente, o SW-RAS estende as categorias de classificação, solução, uso e ativos relacionados, cujos detalhes estão descritos no texto. Visando à experimentação da proposta através de um estudo de caso, desenvolveu-se o Lavoi, um repositório de ativos reutilizáveis baseado no SW-RAS, que foi avaliado num ambiente real de reutilização e desenvolvimento de software de uma grande companhia pública de TI. Uma descrição deste processo de avaliação em um contexto real é também apresentada neste trabalho. A principal contribuição desta dissertação é a proposta, a avaliação e a consolidação de uma extensão do RAS que atende várias de suas lacunas e é suportada por uma ferramenta de software livre.The software reuse faces numerous managerial, technical and cultural barriers in its adoption, and the definition of the structure of reusable software assets is one of these technical barriers. To solve this, the Reusable Asset Specification (RAS) is a de facto standard proposed by OMG. A specification such as the RAS defines and standardizes a reusable asset model, and it is the foundation for the construction and for the use of an asset repository that supports the software reuse. However, for being adopted in the practice, the RAS needs to solve its lacks through its extension and the definition of complementary information. These lacks are detailed in this work. Solving these lacks, the RAS becomes useful to help effectively in the standardization of packaging reusable assets and to guide the structure of the software reuse repository. Some previous works have already partially answered this question, but they attended very specific purposes, did not have a support tool or have not been evaluated in a real context of (re)use. This work proposes the Software Profile RAS (SW-RAS), an extension of the component Profile of RAS, which proposes solutions for its various lacks, including useful information and relevant artifacts pointed out in the literature, based on other reusable asset models, on other RAS extensions and on the experience in the reuse process at software development. Particularly, the SW-RAS extends the categories of classification, solution, usage and related assets, whose details are described in the text. Aiming at the experimentation of the proposal through a case study, the Lavoi was developed, a reusable asset repository based on the SW-RAS, which is was evaluated in a real environment of reuse and software development of a large public IT company. A description of this evaluation process in real context is also presented in this work. The main contribution of this dissertation is the proposal, the evaluation and the consolidation of an extension of RAS that addresses several of its lacks and is supported by a free software tool.

Designing software components for future reuse has been an important area in software engineering. A software system developed with reusable components follows a "with" reuse process while a component designed to be reused in other systems follows a "for" reuse process. This dissertation explores the factors affecting design for reuse and design with reusable components through empirical studies. The studies involve Java components implementing a particular algorithm, a stemming algorithm that is widely used in the conflation domain. The method and empirical approach are general and independent of the programming language. Such studies may be extended to other types of components, for example, components implementing data structures such as stacks, queues etc. Design for reuse: In this thesis, the first study was conducted analyzing one-use and equivalent reusable components for the overhead in terms of component size, effort required, number of parameters, and productivity. Reusable components were significantly larger than their equivalent one-use components and had significantly more parameters. The effort required for the reusable components was higher than for one-use components. The productivity of the developers was significantly lower for the reusable components compared to the one-use components. Also, during the development of reusable components, the subjects spent more time on writing code than designing the components, but not significantly so. A ranking of the design principles by frequency of use is also reported. A content analysis performed on the feedback is also reported and the reasons for using and not using the reuse design principles are identified. A correlation analysis showed that the reuse design principles were, in general, used independently of each other.
Design with reuse: Through another empirical study, the effect of the size of a component and the reuse design principles used in building the component on the ease of reuse were analyzed. It was observed that the higher the complexity the lower the ease of reuse, but the correlation is not significant. When considered independently, four of the reuse design principles: well-defined interface, clarity and understandability, generality, and separate concepts from content significantly increased the ease of reuse while commonality and variability analysis significantly decreased the ease of reuse, and documentation did not have a significant impact on the ease of reuse. Experience in the programming language had no significant relationship with the reusability of components. Experience in software engineering and software reuse showed a relationship with reusability but the effect size was small. Testing components before integrating them into a system was found to have no relationship with the reusability of components. A content analysis of the feedback is presented identifying the challenges of components that were not easy to reuse. Features that make a component easily reusable were also identified. The Mahalanobis-Taguchi Strategy (MTS) was employed to develop a model based on Mahalanobis Distance to identify the factors that can detect if a component is easy to reuse or not. The identified factors within the model are: size of a component, a set of reuse design principles (well-defined interface, clarity and understandability, commonality and variability analysis, and generality), and component testing.

This research on Reusable Launchers was motivated by the need
to reduce substantially the cost of space transportation. The
specific objective was to- explore the perception that
launcher reusability is the key to achieving these major cost
reductions. The exploration was achieved by undertaking a
comparative system study on potentially feasible reusable
launcher concepts, using a consistent set of design tools, a
standard analysis methodology and a standard reference
mission.
To set the background f or the research, the results of an
extensive literature review are 'presented on the vehicle
studies and technology developments that are engaged across
the world on reusable launchers. Comprehensive vehicle
studies appear to be engaged without justification for the
choice of selected concepts in the absence of results from
comparative system studies of reusable launchers. Technology
developments also appear to be engaged without clear links to
needs derived from vehicle system studies.
The challenge of reusability is then addressed. Firstly, to
set the performance and cost targets of reusable launchers,
the capabilities of current expendable launchers are derived.
Secondly, to establish the operational requirements for
reusable launchers, the probable space transportation needs
for the early 21st century are derived. Thirdly, the concepts
and characteristics of reusable launchers are derived,
allowing the selection, on a rationale basis, of a short-list
of 13 potentially feasible reusable launcher concepts for
analysis in the research. The performance equations of reusable launchers are 'then
derived, leading to the preparation of the comparative
analysis tools.
The major work-of the research, which ''comprises the
performance analysis, technical feasibility assessment and
cost"analysis of each candidate vehicle are, then presented
and compared-.
A set of acceptance requirements for performance,, technical
feasibility and operational costs - of reusable launchers is
then -derived. The results of the comparative analysis for
each candidate launcher are then measured , against these
requirements. The results of the comparative analysis show
that only 2 of the' 13 candidate reusable launcher concepts
are able to meet all the acceptance'requirements. These two
acceptable vehicles are both rocket-propelled. They are, ýin
order of preference:
a single-stage-to-orbit, rocket-propelled, vertical
launch and vertical landing vehicle;
a two-stage-to-orbit, rocket-propelled, vertical launch
and horizontal landing vehicle.
The operational ''costs per launch for these two'vehicles,,
based on a utilisation plan of 3 vehicles operating for 20
years at a launch rate of 12 launches per year, was
calculated to be about 20 % of the current costs of the
European Ariane 44L expendable launcher. This warrants their
further evaluation in a thorough feasibility study. The more complex, air-breathing propelled, horizontal launch
and landing vehicles were found to be unable to meet the
performance, technical feasibility and cost requirements:
Several vehicles were found to be unable to deliver a
positive payload mass to orbit;
Several vehicles were found to have technology
requirements that were deemed to be infeasible to
achieve;
Several vehicles were found to have operational costs
ranging from equal to double that
-of
the European Ariane
44L expendable launcher,, which -was- adopted as a
comparative reference vehicle.
The contributions of this research to the advancement of
knowledge on reusable launchers are:
a clear identification of the performance, capability
limits of 13 plausible reusable launcher concepts;
an analysis methodology for determining the performance
capability limits for any reusable launcher concept;
a clear identification of the reasons. for the poor
practical performance of air-breathing propulsion
systems for Earth-to-orbit launchers, which results from
their installed operational characteristics.

Companies often create apps in the same problem domain with similar features. Implementing these features over and over again is inefficient, time consuming, and error prone. This leads to high costs for the developing company and prices which are not competitive on the market. To address these problems we identify reusable features and implement them in a library which is well tested and allows frequent reuse. Features include navigation patterns, lists, menus, animated components, shared components, gallery and so on. With the help of these features programmers can easily create various applications with good design and functionality, reducing the time spent on development and allowing competitive prices for related services and products.

This project consists of and is driven forwards by three forces: PART ONE is the Story Behind, the environmental and political part with problems like waste management, over-consumption, and extreme lack of student housing in the Stockholm region in spite of the politicians’ promises. SECOND PART is the Collecting of Waste that are at hand, showing how much MATERIALS, still fully usable, we just discard of and the investigation of these - with a little creativity and innovation finding strategies to use them in a NEW WAY in the context of architecture, questioning the perception of second-hand materials. AND THIRDLY - reaction! The practical part, a full-scale built proposal with which I tie together this project. As a response to our consumption-oriented society, I collected whatever thrown away material at hand right here on the architecture school. With this material and the strategies discovered, I constructed a small student dwelling on a forgotten and unused space on the architecture school’s roof, making a statement towards the disappointing development of the student housing situation.Detta projekt består av och drivs framåt av tre krafter: DEL ETT - historien bakom, den politiska delen med fokus på miljö, såsom avfallshantering, överkonsumtion, samt den extrema bristen på studentbostäder i Stockholmsregionen trots politikernas löften. ANDRA DELEN - insamlande av avfallsmaterial till hands, som visar hur mycket MATERIAL (fortfarande fullt användbart) som vi slängs, samt undersökningen av dessa. Med lite kreativitet och innovation hitta strategier för att använda materialen på ett nytt sätt inom ramen för arkitektur. Ett ifrågasättande av uppfattningen av begagnade material. DEL TRE - reaktion! Den praktiska delen, ett fullskaligt byggt förslag som sammanfattar projektet. Som en respons på vårt konsumtionsstyrda samhälle samlade jag in slängda objekt till hands på arkitekturskolan. Med detta material och med de upptäckta strategierna konstruerade jag en liten studentbostad på en bortglömd och oanvänd plats på arkitekturskolans tak - ett statement mot den negativa situationen vad gäller studentboende i Stockholm.

In this work I illustrate an approach to the development of a library of problem solving components for knowledge modelling. This approach is based on an epistemological modelling framework, the Task/Method/Domain/Application (TMDA) model, and on a principled methodology, which provide an integrated view of both library construction and application development by reuse. The starting point of the proposed approach is given by a task ontology. This formalizes a conceptual viewpoint over a class of problems, thus providing a task-specific framework, which can be used to drive the construction of a task model through a process of model-based knowledge acquisition. The definitions in the task ontology provide the initial elements of a task-specific library of problem solving components. In order to move from problem specification to problem solving, a generic, i.e. taskindependent, model of problem solving as search is introduced, and instantiated in terms of the concepts in the relevant task ontology, say T. The result is a task-specific, but method-independent, problem solving model. This generic problem solving model provides the foundation from which alternative problem solving methods for a class of tasks can be defined. Specifically, the generic problem solving model provides i) a highly generic method ontology, say M; ii) a set of generic building blocks (generic tasks), which can be used to construct task-specific problem solving methods; and iii) an initial problem solving method, which can be characterized as the most generic problem solving method, which subscribes to M and is applicable to T. More specific problem solving methods can then be (re-)constructed from the generic problem solving model through a process of method/ontology specialization and method-to-task application. The resulting library of reusable components enjoys a clear theoretical basis and provides robust support for reuse. In the thesis I illustrate the approach in the area of parametric design.

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, CaliforniaComputer Sciences Corporation, Realtime Data Systems Center has developed, integrated, tested, and delivered several large telemetry systems to various ranges over the past eight years. One key to the success of these systems has been the ability to build on a software base to meet unique range processing requirements for aircraft, missiles, and related weapons systems. Reusable software means reduced procurement and life cycle costs. The ability to successfully reuse software for new systems with new requirements lies not only in the fundamentals of modular system design, but in the ability of the people to comprehend the design, and adapt the software to new requirements. As advanced telemetry processing needs meet reduced budgets, the successful systems integrator will be relying more and more on an ability to adapt existing systems to meet new challenges.

Abstrakt: This report examines different control design methods, linear as well as nonlinear, for a suborbital reusable launch vehicle. An investigation of the natural vehicle behavior is made, after which a baseline linear controller is constructed to fulfill certain handling quality criteria. Thereafter the nonlinear cascade control methods block backstepping and nonlinear dynamic inversion via time scale separation are examined and used to construct two nonlinear controllers for the vehicle. Optimal controllers, in terms of three different criteria, are found using the genetic optimization algorithm differential evolution. The optimal controllers are compared, and it is found that nonlinear dynamic inversion via time scale separation performs better than block backstepping with respect to the cases investigated. The results suggest control design by global optimization is a viable and promising complement to classical methods.

Period poverty is a problem mainly found in places characterized by poverty. The lack of means for women and girls to properly handle their menstruation is the essence of the problem. With a lack of both quantity and quality regarding water often being an issue in such places, the hygiene is a constant challenge. Two different kinds of sanitary products are used globally, disposable and reusable. The reusable ones are often being made of cotton or other absorbent materials. Regardless the material, reusable products need cleaning between the times of use, which could be a challenge when water is not always accessible. To have a reusable sanitary pad that efficiently can be cleaned with low amounts of resources is important, especially in impoverished places. Spacerpad is a reusable sanitary pad and a part of a project at the University of Borås. The aim for the project is to reduce period poverty and to educate women and girls in menstrual hygiene management. The pad is made of polyester which does not absorb blood or water, instead the pad merely contains the fluids. This thesis was conducted as a field study in Nairobi, Kenya. The study aimed to simulate a menstruation, in order to analyze the microbial activity in two different reusable sanitary pads, during as well as after menstruation. With the influences from interviews and resources found in Kibera (a slum in Nairobi) a simulation of five days was executed, with nutrient solution instead of menstrual blood. The Spacerpad and a cotton pad were exposed to the same procedures and the effects of washing and drying were studied. The microbial activity was measured with the help of dipslides, a growth medium. The results of this study show that both Spacerpad and the cotton pad could be carriers of heavy growth of bacteria. Increasing microbial activity throughout the simulation as the days went by, ended with a dividing result after a soap wash as the final washing procedure. The pad made of cotton still carried above slight growth, compared to Spacerpad that showed almost no activity after the final cleanse. Even though the microbial activity reached high levels during the simulation, the fact that the Spacerpad can be cleaned with limited resources could be reason enough to consider the Spacerpad as a sufficiently sanitary product in an impoverished place like Kibera.Mensfattigdom är något som vanligtvis återfinns på platser präglade av fattigdom. Bristen på medel för kvinnor och flickor att kunna hantera sin menstruation är kärnan av problemet. Med en brist i kvantitet och kvalitet på vatten som ett vanligt problem på sådana platser är det en konstant utmaning att upprätthålla sin hygien. Menstruationsskydd delas in i två olika typer, engångs- och återanvändningsbara produkter. De återanvändningsbara produkterna består ofta av bomull eller andra absorberande material. Oavsett material måste produkterna rengöras mellan användningarna, vilket kan vara en utmaning på platser där vatten inte alltid är tillgängligt. Tillgång till en återanvändningsbar binda som kan rengöras med små resurser är viktigt, speciellt på platser som kännetecknas av fattigdom. Spacerpad är en återanvändningsbar binda, framtagen som del av ett projekt vid Högskolan Borås, vars syfte är att reducera mensfattigdom och samtidigt utbilda kvinnor och flickor om menstruation och hygien. Bindan är tillverkad av polyester som inte absorberar blod eller vatten, vilket gör att bindan snarare håller vätskorna på plats. Denna uppsats gjordes som en fältstudie på plats i Nairobi, Kenya och hade som mål att simulera en menstruation. Detta för att se hur den mikrobiella aktiviteten skulle kunna se ut, under och efter en menstruation. Med influenser ur intervjuer och tillgångar från Kibera (ett slumområde i Nairobi) genomfördes simulationen med näringslösning som substitut till mensblod. I simulationen studerades effekten av tvätt och tork på den mikrobiella aktiviteten. Spacerpad och en bomullsbinda genomgick samma processer där aktiviteten mättes med hjälp av dipslides, ett växtmedium. Resultaten från denna studie visar att både Spacerpad och bomullsbindan kan vara bärare av hög tillväxt av bakterier. En ökande bakteriell aktivitet genom testdagarna, slutade med ett tudelat resultat efter en tvåltvätt som sista procedur. Bindan av bomull hade lätt tillväxt, medan Spacerpad knappt visade någon tillväxt alls efter den sista rengöringen. Den mikrobiella aktiviteten hos Spacerpad nådde höga nivåer under simulationen. Trots det så gör förmågan att kunna rengöras med låg åtgång av resurser, att den kan anses vara sanitär nog för att användas på platser präglade av fattigdom, som i Kibera.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, CaliforniaThe SMART (Smart Modularized Advanced Reusable Telemeter) is an advanced telemetry system. The SMART system enhances the quality of a weapon system by providing an adaptable built-in telemetry capability for the weapon. Existing weapon telemetry systems are centralized, separate components which require many fault-prone interconnections. This system reduces the number of interconnections and provides higher performance than current systems. The modular system uses a high data-rate serial data link that connects remote measurement modules located throughout the unit-under-test. A smart processor is used to analyze and compress data from the various modules prior to transmission, making more effective use of the telemetry bandwidth. The smart processing unit also adapts the measurement units for changing test conditions on-the-fly. The system will allow more complete testing of the weapon system and solve a broader range of problems. The goal of the SMART project is to utilize the most advanced technology to overcome the current design methodologies that have perpetuated shortcomings in present systems. This project is being conceptualized to encompass a broader range of telemetry applications beyond the present weapon systems at Sandia.

Context: Software reuse is considered as the key to a successful software development because of its potential to reduce the time to market, increase quality and reduce costs. This increase in demand made the software organizations to envision the use of software reusable assets which can also help in solving recurring problems. Till now, software reuse is confined to reuse of source code in the name of code scavenging. Now a day, software organizations are extending the concepts of software reuse to other life cycle objects as they realized that reuse of source code alone does not save money. The academia has put forward some assets as reusable and presented methods or approaches for reusing them. Also, for a successful software reuse the organizations should assess the value of reuse and keep track on their reuse programs. The other area which is vital for software reuse is the maintenance. Maintenance of reusable software has direct impact on the cost of the software. In this regard, academia has presented a number of techniques, methods, metrics and models for assessing the value of reuse and for maintaining the reusable software. Objectives: In our thesis, we investigate on the reusable assets and the methods/ approaches that are put forward by the academia for reusing those assets. Also a systematic mapping study is performed to investigate what techniques, methods, models and metrics for assessing the value of reuse and for maintaining the reused software are proposed and we also investigate their validation status as well. Methods: The databases like IEEE Xplore, ACM digital library, Inspec, Springer and Google scholar were used to search for the relevant studies for our systematic mapping study. We followed basic inclusion criteria along with detailed inclusion/exclusion criteria for selecting the appropriate article. Results: Through our systematic mapping study, we could summarize the list of 14 reusable assets along with the approaches/methods for reusing them. Taxonomy for assessing the value of reuse and taxonomy for maintaining the reusable software are presented. We also presented the methods/metrics/models/techniques for measuring reuse to assess its value and for maintaining the reusable software along with their validation status and areas in focus. Conclusion: We conclude that, there is a need for defining a standard set of reusable assets that are commonly accepted by the researchers in the field of software reuse. Most metrics/models/methods/approaches presented for assessing the value of reuse and for maintaining the reuse software are academically validated. Efforts have to be put on industrially validating them using the real data.

The work presented in this report revolves around the higher levels of reuse, specifically reusing knowledge, designs and architectures. All this in the means of enhancing the initial stages of systems development projects, where an emphasis is made on common understanding between the parties involved, which can be achieved by using reuse as a technique for rapid prototyping and demonstrating possible solutions to customers and their end-users. A systematic procedure to facilitate this reuse is produced, with consideration to current practices and methodologies. At the core of the procedure is a template for system descriptions, used to describe a company's previously constructed systems in a way that makes them accessible throughout the company. The template's key necessary features are identified as enabling a collection of systems to be searched and each description to present a clear overview of what the system enables its users to do. Another key aspect of systems development and reusing knowledge, as well as systems, is the social network of the individuals at a company. By applying different theories of requirement engineering and functionality descriptions, the template shows promise in aiding system developers in their work. Additionally, a demonstration application based on the system description template is presented in order to emphasize the opportunities given by the procedure.

Most neutral atom quantum computing experiments rely on destructive state detection techniques that eject the detected qubits from the trap. These techniques limit the repetition rate of these experiments due to the necessity of reloading a new quantum register for each operation.
We address this problem by developing reusable neutral atom qubits. Individual Rubidium 87 atoms are trapped in an optical lattice and are held for upwards of 300 s. Each atom is prepared in an initial quantum state and then the state is subsequently detected with 95% fidelity with less than a 1% probability of losing it from the trap. This combination of long storage times and nondestructive state detection will facilitate the development of faster and more complex quantum systems that will enable future advancements in the field of quantum information.

Pełny tekst źródłaStreszczenie:
Because software development is increasingly expensive and timeconsuming, software reuse gains importance. Aspect-oriented software development modularizes crosscutting concerns which enables their systematic reuse. Literature provides a number of AOP patterns and best practices for developing reusable aspects based on compelling examples for concerns like tracing, transactions and persistence. However, such best practices are lacking for systematically reusing invasive aspects.
In this paper, we present the ‘callback mismatch problem’. This problem arises in the context of abstraction mismatch, in which the aspect is required to issue a callback to the base application. As a consequence, the composition of invasive aspects is cumbersome to implement, difficult to maintain and impossible to reuse.
We motivate this problem in a real-world example, show that it persists in the current state-of-the-art, and outline the need for advanced aspectual composition mechanisms to deal with this.

This research aims to propose an integrated method, which combines all the aspects required to reduce environmental impact from waste packaging and to increase knowledge on the best way to enhance reusable packaging. Through a review of the extant literature, a conceptual framework was designed of the most important dimensions to enhance reusable packaging amongst society and industries The main contributions in the research are the development of a Social Behaviour Aspect Model (SBAM) and the creation of reusable packaging attributes checklist. The SBAM can help industries focus on having high knowledge about reuse of packaging and to cooperate with communities to develop personal and social values and norms during the designing of reusable packaging. SBAM is the output from the first phase, which showed the importance of making an effort to develop packaging for consumers to reuse. The reusable packaging attributes checklist can provide a guideline for manufacturers/designers who intend to develop packaging sustainability performance through designing reusable packaging, and contribute to meet and interpret the reuse of packaging requirements and procedures. It also determines the environmental impact of reusable packaging attributes, which many industries are concerned about. The reusable packaging attributes checklist is the output from the second and third phases. The System Dynamic (SD) method was the approach used to determinate the interaction between social aspects and reusable packaging. The Normal Average, Codes and Coding and factor analysis with Principal Component Analysis (PCA) approaches were used to determine the reusable packaging attributes checklist. The last phase of the research was the conduction of a case study of a real company which needs to increase the amount of reusable packaging it uses and which seeks to reduce its environmental impact. All methods used in this research have both a quantitative and a qualitative nature. Data was collected by evaluation of consumers' responses and experts' experiences, as provided in the questionnaires. This research opens up opportunities for improving packaging and meeting sustainable profits and provides valuable information based on social, economic and environmental benefits of reusable packaging. The novelty of this research can help industries to investigate the most important areas for development within communities to enhance the use of reusable packaging and also facilitate the process-based change from one-way packaging to reusable packaging effectively with reduction of environmental impact.

Message passing is a fundamental building block of many networked systems. It provides a simple abstraction for programmers to transfer data between different hosts and processes when building distributed systems. Message-passing semantics and abilities vary between different systems and frameworks, and different semantics have different requirements. Kompact is an actor framework written in and for the Rust programming language. With the target use-case of stream-processing in mind, we implement a new Networking layer for Kompact, with a novel buffer-pool implementation and custom made network-channel abstraction. A previous evaluation of different actor frameworks has indicated that Erlang outperforms every other actor-framework in throughput of networked messages, including Kompact. Our experiments indicate that the new networking layer increases the network throughput of Kompact by up to 4.6x compared to the previous version, and achieves 2.8x higher throughput than Erlang.Överföring av meddelanden är en fundamental funktion i många applikationer som använder nätverkskommunikation. Diskreta meddelanden är en simpel abstraktion för programmerare att nyttja för data-överföringar och kommunikation mellan värdar och processer i distribuerade system. Meddelandeöverföringens semantik och förmåga varierar mellan olika system och ramverk, och olika användningsområden ställer olika krav på överföringens förmågor. Kompact är ett aktörsramverk skrivet i och för programspråket Rust. Med ett användningsområde i dataströmsprocessering implementeras ett nytt nätverkslager för Kompact, med en ny typ av buffer-pool och en skräddarsydd nätverkskanal-abstraktion. Tidigare utvärderingar av olika aktörsramverk indikerar att Erlang presterar bättre än alla andra aktörsramverk med avseende på genomströmning av nätverksmeddelanden. Våra experiment indikerar att det nya nätverkslagret ökar genomströmningsförmågan av Kompact med up till 4.6x jämfört med den tidigare versionen, och upp till 2.8x högre genomströmningsförmåga än Erlang.

Software reuse can occur in various places during the software development cycle. Reuse of existing source code is the most commonly practiced form of software reuse. One of the key requirements for software reuse is readability, thus the interest in the use of data abstraction, inheritance, modularity, and aspects of the visible portion of module specifications. This research analyzed the contents of software reuse libraries to answer the basic question of what makes a good reusable software component. The approach taken was to measure and analyze various software metrics as mapped to design characteristics. A related research question investigated the change in the design principles over time. This was measured by comparing sets of Ada reuse libraries categorized into two time periods. It was discovered that recently developed Ada reuse components scored better on readability than earlier developed components. A benefit of this research has been the development of a set of "design for reuse" guidelines. These guidelines address coding practices as well as design principles for an Ada implementation. C++ software reuse libraries were also analyzed to determine if design principles can be applied in a language independent fashion. This research used cyclomatic complexity metrics, software science metrics, and traditional static code metrics to measure design features. This research provides at least three original contributions. First it collects empirical data about existing reuse libraries. Second, it develops a readability measure for software libraries which can aid in comparing libraries. And third, this research developed a set of coding and design guidelines for developers of reusable software. Future research can investigate how design principles for C++ change over time. Another topic for research is the investigation of systems employing reused components to determine which libraries are more successfully used than others.

Adaptive reuse of manufacturing plants in post-industrial countries has become an increasing trend. In the United States, evidence of our industrial past is present in both urban and rural landscapes. The appearance of "brownfields" is due to the change in the U.S. economy from heavy industry and the manufacturing of commodities to the digitized products and supports required of the information age. The need to recycle these lands is part of the realities we face, as we become increasingly aware of the environmental damage caused by the industrial age. Paterson, NJ is the oldest industrial site in America founded by Alexander Hamilton. He chose it because the seventy-foot Great Falls was a prime source of hydroelectric power. He laid foundations in the city that helped make Paterson a prime textile-manufacturing center throughout the nineteenth and early part of the twentieth centuries. Since the 1960s, Paterson has experienced a decline in its industrial economic base. The city has sought to regenerate interest in the area through historic trails and the attraction of the Great Falls. These efforts have failed. However, through out its history Paterson has been the site of adaptive reuse. The mills and factories constantly had to change in order to keep pace with new technology. Currently, several mills have been renovated to form apartments for artists. While providing picturesque housing, these renovated mills no longer have a place in the piecemeal industries that still exist. This type of renewal has not helped to reunify this community. To counteract these singular interventions I have proposed reprogramming the central industrial area around the Falls as a center for Ecologists and Environmental Artists. The urban strategy I have adopted is one of creating desire for the current transient population to remain in the area and reinvest in the existing infrastructure. I have used nature to unify the area by artificially reinserting nature where, before Hamilton, nature flourished. A path unifies the area taking the pedestrian through the natural and artificial (man-made) topography of this landscape. The landscape offers sectional characteristics, which I have tried to make the pedestrian aware: aerial, canopic, terrestrial, aquatic, and sub-terrestrial. The path illustrates that we are always moving between sky and water. While the mountain and river offer some geographical orientation, once the pedestrian is embedded in the existing urban fabric, his sense of direction may become obfuscated. The path begins by orientating the pedestrian North and over the course of his walk, if repeated over the course of a year, he would find that the summer and winter solstices help strengthen his sectional placement within this landscape. Along the path I have interjected sustainable infrastructures in order to show how the industrial past can help us revitalize our landscape for a post-industrial future. In my own renovation of certain buildings, I have tried to create a balance between nostalgia for the past and romance for new technology. F or nostalgia does not necessitate a recreation of what once was, but can reintroduce us to the past's own love and desire for the future.

This thesis describes the design, implementation, and evaluation of a dynamic program analysis framework called Tralfamadore. Three key aspects differentiate Tralfamadore from traditional dynamic analysis frameworks. First, analyses execute offline based on detailed CPU traces. This approach enables multiple analyses on the same execution, and analyses not foreseen at the time of execution. Using detailed traces also decouples analysis from instrumentation, simplifying the design of analyses and of the framework. Second, Tralfamadore supports the analysis of operating system execution. Third, the architecture of the analysis engine promotes the construction of analyses that are composable and reusable. New analyses can be written by mostly reusing existing components. Although these aspects have been investigated in isolation in the past, Tralfamadore is the first dynamic analysis framework to address all three at once.

Spacecraft missions have traditionally sacrificed fully functional hardware and entire vehicles to achieve mission objectives. Propellant tanks are typically jettisoned at different stages in a spacecraft mission and left to burn in the atmosphere after one use, creating a substantial amount of waste and redundancy which leads to high operational costs. Spaceflight programs cannot continue to rely on current methods of discarding hardware, since the cost to transport materials from Earth is extremely high. Significant improvements need to be made in recovery and reuse of valuable hardware, to be able to lower costs per mission and increase the number of missions. Strategies need to focus on avoiding complete loss of hardware. This thesis proposes a new class of materials called digital material skins, that will revolutionize the fabrication and assembly of everyday functional objects to spacecraft structural applications, by embedding the intelligence not in the fabrication tools but in the materials themselves, to create reusable and recyclable materials. A workflow for digital material skins is also demonstrated, based on existing fabrication tools to rethink the entire lifecycle of functional skins from design to fabrication to disassembly. When a child builds a structure out of Legos, precision lies not in the human assembler but in the material, component geometry, and linking mechanism to dictate how and where each material interlocks within the larger material system. A digital material skin is made of discrete units with a finite set of parts and joints used to construct a functional structural skin for airtight,waterproof, high or low pressure applications.The surface is enclosed or the surface is open. Digital material skins are used to construct any shape or interior volume that is regular or amorphous. A digital material skin is an exterior structure which relies on an interior digital material structure for support, or a digital material skin is self-supported with few or no interior support. Parts and links are arranged and configured in a regular pattern to create a surface larger than the units themselves. The skin is part of a larger assembly or part of a single unitary structure of any size or shape. The skin may have a thickness that is smaller or larger than any dimension. The skin is made of one or more layers of one material or multi-material units. The joints are reversible, allowing transfer of forces from one unit to adjacent units to create a continuous bulk material. The work will develop a prototype of a digital material skin concept for pressure vessel skins, and adumbrate a new design methodology that considers the entire lifecycle of digital material skins.

Frameworks have been used since the early eighties. Now that frameworks are becoming increasingly popular, several problems are surfacing. Those problems can be categorized into evolution problems (i.e. problems with changes over time) and composition problems (i.e. problems that occur when more than one framework is used in an application). This master thesis focusses on preventing these problems in an early stage in the development of a framework. Guidelines for building OO Frameworks are presented and the guidelines are tried out in the domain of communication protocols.

The practice of adaptive reuse has grown in popularity in the United States over the past few decades, with now about 90% of architect-commissioned work involving some interaction with an existing structure. While the practice of reuse has existed informally in the form of garage-as-guest house or barn-as-garage conversions and so on, it is only since the late 1960s that architects and engineers have begun to approach it critically, as a design problem. It is often lauded for fostering the development of a sustainable built environment, however, it has its unique challenges. This thesis traces a brief history of the designer's role in the sustainable development discourse, with focused attention paid to the adaptive reuse solution. Furthermore, it attempts to identify the challenges and discuss how they each pertain to the architect, the preservationist, and the engineer. Through the examination of reuse case studies, a coarse classification of project typologies. The second portion of the thesis tackles a specific reuse problem in the Old Post Office in Chicago, Illinois. The Post Office was selected because of its heavily planned context, its historical and cultural significance, the real interest that has been expressed in its reuse, and its size.
(cont.) The thesis builds on the earlier classification system to propose an integrated strategy with which to approach the redevelopment of the building. The final part of the thesis briefly describes a few environmental evaluation methods that might be used to judge the sustainability of the reuse project. The proposed solution is analysed to see if the design decisions made with environmental sustainability in mind can be quantified.

Pełny tekst źródłaStreszczenie:
This thesis reports on experiments into whether abrasives, lasers or solvents can remove ordinary black toner-print from ordinary white office paper in a way that leaves the paper reusable. If it could be ‘un-printed’ then waste office-paper could be reused immediately, without the need for recycling. There has been no academic work on un-printing, but some relevant patents have been filed. The second chapter reviews these patents according to whether they remove, obscure or de-colour the original print. It is not clear from the patents whether toner-print can be removed by abrasives, lasers, or solvents without rendering the paper unusable. These three approaches are tested experimentally and the results reported in chapters 3, 4 & 5. Abrasives can remove toner-print with limited damage to the underlying paper by operating in an adhesive wear regime. This involves making ten passes with a fine P800 abrasive rubbing at high speeds (6 m/s) and low loads (0.3N). Longer wavelength lasers are able to remove the toner-print and leave blank paper undamaged by operating at 1 W and 10kHz in the 1064 nm wavelength and scanning across the surface eight times at 400 mm/s. Unfortunately the paper beneath the print is yellowed during removal. A 40:60 mixture chloroform and dimethylsulfoxide effectively dissolves toner without dissolving paper if agitated with ultrasound for four minutes.

A major reengineering goal is software reuse. Effective reuse of knowledge, processes and products from previous software developments can reduce costs and increase both productivity and quality in software projects.This thesis extensively tests five projects produced by the graduate software engineering class at Ball State University. Each project has the same set of requirements.Each project is also analyzed based on subjective criteria, for example documentation, use of mnemonics for variable names and ease of understanding. Based on the outcome of testing and subjective analysis, reusable parts are identified.Metrics are collected on all of these projects. This thesis compares the metrics collected on the modules identified for reuse, and the same metrics collected on the non-reusable modules, to determine if there is a statistically significant difference in those metrics between the two groups. Metrics which are good predictors of reusable modules are identified.Metrics which are found to be good predictors of reusable modules include: number of in-parameters, number of data structure manipulations and central calls.Department of Computer Science
