Abstract:

In the big data context, the growing volume of textual data presents challenges for traditional structured data-based decision support systems (DSS). DSS based on structured data is difficult to process the semantic information of text data. To meet the challenge, this thesis proposes a solution for the Decision Support System (DSS) based on machine Learning and qualitative analysis, namely TLE-DSS. TLE-DSS refers to three critical analytical modules: Thematic Analysis (TA), Latent Dirichlet Allocation (LDA)and Evolutionary Grounded Theory (EGT). To better understand the operation mechanism of TLE-DSS, this thesis used an experimental case to explain how to make decisions through TLE-DSS. Additionally, during the data analysis of the experimental case, by calculating the difference of perplexity of different models to compare similarities, this thesis proposed a solution to determine the optimal number of topics in LDA. Meanwhile, by using LDAvis, a model with the optimal number of topics was visualized. Moreover, the thesis also expounded the principle and application value of EGT. In the last part, this thesis discussed the challenges and potential ethical issues that TLE-DSS still faces.

Abstract:

It is known the case of the public attorneys that, having the opportunity to settle a controversy aroused between the public entity and the contractor, prefer to submit that dispute to arbitration with higher costs that this decision cause to the State. The reason? The concern of having «the reasonableness of his decision to settle the dispute» subjected to an administrative responsibility procedure.This paper aims to discuss this problem and analyze a possible solution. Thus, taking into consideration the Colombian experience and the recent Peruvian regulation in the «Reglamento de la Ley de APPs», the authors suggest to include in the «Nueva Ley de Contrataciones del Estado» the «Amicable Compositor» as a mechanism of alternative dispute resolution.
Es conocido el caso del procurador público que ante la posibilidad de transar los conflictos que surgen entre las entidades públicas y los contratistas, prefiere llevarlos a arbitraje con los mayores costos que dicha decisión genera para el Estado. El motivo responde a la preocupación de que se cuestione «la razonabilidad de su decisión de transar» imputándole responsabilidad mediante acciones de control.El presente artículo tiene como finalidad traer a discusión esta problemática así como una posible solución. De esta forma, teniendo en consideración la experiencia colombiana así como su reciente regulación en el Reglamento de la Ley de APPs, los autores proponen incluir en la Nueva Ley de Contrataciones del Estado la figura del «Amigable Componedor» como mecanismo alternativo de solución amigable de conflictos.

Abstract:

Cette thèse vise à contribuer à la compréhension des cycle de vie d’une opération humanitaire (HOLC). Gestion de la chaîne d'approvisionnement humanitaire (HSCM) dans un contexte de mise en perspective et dans l’objectif de proposer un modèle décisionnel qui s'applique aux phases de HOLC lors d’une situation réelle. Cela inclut la mise en oeuvre du modèle proposé pour concevoir et développer un outil d'aide à la décision afin d'améliorer les performances de la logistique humanitaire tant dans les opérations de secours nationaux qu’internationaux.Cette recherche est divisée en trois phases. La première partie vise à présenter le sens de l'étude ; la zone de recherche prise en compte pour la gestion de la chaîne d'approvisionnement (SCM) doit être clairement définie. La première phase consiste à clarifier et définir le HSCM HL, la gestion de la chaîne d'approvisionnement commerciale (CSCM) et le SCM, ainsi que la relation entre ces différents éléments. La gestion du cycle de vie du projet (PLCM) et les différentes approches sont également présentés. La compréhension de la différence entre la gestion du cycle de vie du projet (PLM) et la PLCM est également nécessaire, cela ne peut être abordé dans la phase de cycle de vie de l'opération humanitaire. De plus, les modèles Multiple-Criteria Decision Making (MCDM) et l’aide à la décision concernant le HL sont analysés pour établir le fossé existant en matière de recherche. Les approches MCDM qui mettent en oeuvre le système d'aide à la décision (DSS) et la manière dont le MAS a été utilisé dans le contexte HSCM sont étudiées.La deuxième phase consiste en la proposition d’un modèle décisionnel fondé sur l’approche MCDM à l'appui de la décision du décideur avant qu'il/elle prenne des mesures. Ce modèle prévoit le classement des alternatives concernant l'entrepôt, le fournisseur et le transport au cours des phases de HOLC. Le modèle décisionnel proposé est réalisée en 3 scénarios. I. La décision en 4phases HOLC – opération de secours internationale de la Croix-Rouge Française (CRF). II. La décision en3phases HOLC – opération nationale dela Croix-Rouge thaïlandaise (TRC). III. La décision au niveau de la phase de réponse HOLC – opération internationale du TRC dans quatre pays. Dans cette phase, le scénario I et II sont réalisés étape par étape au travers de calculs numériques et formules mathématiques. Le scénario III sera présenté dans la troisième phase. Pour établir trois scénarios, les données internes recueillies lors des entretiens avec le chef de la logistique de la Croix-Rouge Française, et le vice-président de la fondation de la Coix-Rouge thaïlandaise, seront utilisées. Les données externes proviennent de chercheurs qui sont des experts dans le domaine HL ou le champ du HSCM, de la littérature, et de sources issues des organismes humanitaires (documents d’ateliers, rapports, informations publiées sur leurs sites officiels).Dans la troisième phase, une application Internet multi-critères (decision support system MCDSS WB) mettant en oeuvre le modèle proposé est élaborée. Afin d'atteindre une décision appropriée en temps réel, le WB-MCDSS est développé sur la base d’un protocole client-serveur et est simple à utiliser. Le dernier mais non le moindre ; une application de validation du modèle est réalisée à l'aide de l'approche de l'analyse de sensibilité
This thesis aims to contribute to the understanding of HOLC in context of the HSCM and to propose a decision model which applies to the phases of HOLC the decision making regarding a real situation . This include the implementation of the proposed model to design and develop a decision support tool in order to improve the performance of humanitarian logistics in both national and international relief operations.This research is divided into three phases; the first phase is to clarify and define HL among HSCM, commercial supply chain management (CSCM) and SCM and their relationship. Project Life Cycle Management (PLCM) approaches are also presented. The difference between project life cycle management (PLM) and PLCM is also required to distinguish a clear understanding which can be addressed in the phase of humanitarian operation life cycle. Additionally, the literature of Multiple-Criteria Decision Making (MCDM) models and existing decision aid system for HL are analyzed to establish the research gap. The MCDM approaches which implement the decision support system (DSS) and lastly how DSS has been used in the HSCM context.The second phase is to propose a decision model based on MCDM approaches to support the decision of the decision maker before he/she takes action. This model provides the ranking alternatives to warehouse, supplier and transportation over the phases of HOLC. The proposed decision model is conducted in 3 scenarios; I. The decision in 4-phase HOLC, international relief operation of French Red Cross (FRC). II. The decision on 3-phase HOLC, national operation by the Thai Red Cross (TRC). III. The decision on response phase HOLC, international operation by the FRC in four countries. In this phase, the scenario I and II are performed step by step though numerical calculation and mathematical formulas. The scenario III will be presented in the third phase.In the third phase, an application of web-based multi-criteria decision support system (WB-MCDSS) which implement the proposed model is developed. The web-based multi-criteria decision support system is developed based on the integration of analytical hierarchy process (AHP) and TOPSIS approaches. In order to achieve an appropriate decision in a real time response, the WB-MCDSS is developed based on server-client protocol and is simple to operate. Last but not least, a validation application of the model is performed using the sensitivity analysis approach

Mestrado em Engenharia de Computadores e Telemática
More and more every terminal behaves as a window to the web, being computers, smartphones, tablets, etc. With the advent of web technologies and its globalization, more and more service providers have to adapt to the new reality and follow the trend in order to not loose clients and even the quality of service. This evolution towards web applications has been increasingly observed in the tools used in day-to-day tasks. When leading companies in their market segment propose to make this technological evolution in its products and services, several factors must be studied and taken into account. In the case of solutions using real time communications integrated with its own hardware, several solutions propose to solve the problem, each with its pros and cons, but giving priority to the cutting-edge technologies, which, preferably are originally designed to answer the matters in the product context. Hence a priority to a study to answer the relevant matters for the product as well as the necessary tests to validate the proposed theory.

Abstract:

With the globalisation and constant changes in the marketplace, enterprises are adapting themselves to face new challenges. Therefore, strategic corporate alliances to share knowledge, expertise and resources represent an advantage in an increasing competitive world. This has led the integration of companies, customers, suppliers and partners using networked environments. This thesis presents three novel solutions in the tooling area, developed for Seco tools Ltd, UK. These approaches implement a proposed distributed computing architecture using Internet technologies to assist geographically dispersed tooling engineers in process planning tasks. The systems are summarised as follows. TTS is a Web-based system to support engineers and technical staff in the task of providing technical advice to clients. Seco sales engineers access the system from remote machining sites and submit/retrieve/update the required tooling data located in databases at the company headquarters. The communication platform used for this system provides an effective mechanism to share information nationwide. This system implements efficient methods, such as data relaxation techniques, confidence score and importance levels of attributes, to help the user in finding the closest solutions when specific requirements are not fully matched In the database. Cluster-F has been developed to assist engineers and clients in the assessment of cutting parameters for the tooling process. In this approach the Internet acts as a vehicle to transport the data between users and the database. Cluster-F is a KD approach that makes use of clustering and fuzzy set techniques. The novel proposal In this system is the implementation of fuzzy set concepts to obtain the proximity matrix that will lead the classification of the data. Then hierarchical clustering methods are applied on these data to link the closest objects. A general KD methodology applying rough set concepts Is proposed In this research. This covers aspects of data redundancy, Identification of relevant attributes, detection of data inconsistency, and generation of knowledge rules. R-sets, the third proposed solution, has been developed using this KD methodology. This system evaluates the variables of the tooling database to analyse known and unknown relationships in the data generated after the execution of technical trials. The aim is to discover cause-effect patterns from selected attributes contained In the database. A fourth system was also developed. It is called DBManager and was conceived to administrate the systems users accounts, sales engineers’ accounts and tool trial monitoring process of the data. This supports the implementation of the proposed distributed architecture and the maintenance of the users' accounts for the access restrictions to the system running under this architecture.

Abstract:

The increasing competition between telecommunication service providers (TSPs) and the large amounts of human resource costs incurred to provision telecommunication services to small, medium and micro enterprises (SMMEs), highlight the need for effective self-service provisioning methods to reduce costs. Existing service provisioning methods do not effectively support SMMEs in the service provisioning process. The current methods used are manual and Web-based. The manual service provisioning method is labour and time-intensive. TSPs are being forced to cut human resource costs as the profit margins for provisioning services are narrow due to competition. The current web-based systems do not allow SMMEs to effectively purchase services as they provide long textual lists to consult and limited information about services. The objective of this research was to develop an intelligent web-based self-service system to support SMMEs in telecommunication service provisioning, using a Design Science Research methodology. A constraint-based, knowledge-based recommender system was selected as the most appropriate intelligent system to support telecommunication service provisioning. A prototype called SelPro was developed as a solution to address the shortcomings of the current ineffective service provisioning methods available for SMMEs. SelPro incorporates an interactive wizard-style user interface with dynamic recommendations to support novice users as well as an expert interface which provides less user support. An expert review and a user study were conducted to determine if SelPro was usable, useful and effective. SelPro was perceived as being usable for SMMEs wishing to purchase telecommunication services. Expert participants were satisfied with the usability of SelPro and perceived it as being useful, easy to use and easy to learn. SelPro was considered effective because of the high task success ratings provided by the participants using the two interfaces. The research determined that intelligent web-based self-service provisioning can be used to effectively support SMMEs in telecommunication service provisioning. General design recommendations for similar systems were proposed and future work will involve using intelligent systems to support large enterprises in telecommunication service provisioning.

Abstract:

Abstract The development of embedded systems is becoming increasingly challenging; it is intellectually demanding knowledge work that requires collaboration among a wide range of skills. Software development is a largely cognitive activity, based on the worker’s internal mental processes rather than on physical labour. Developers face several individual and team cognition-related challenges in their work, including complex decision-making and problem-solving processes. Therefore, it is suggested that the software development process should be modelled as a set of problem-solving activities. This thesis proposes that supporting the cognitive work of collaborative development requires addressing the entire system’s life cycle with practical solutions. In this work, the above-mentioned challenges are addressed in terms of communication and collaboration practices, knowledge management and coordination, and transparent tools and processes. Moreover, these solutions are integrated into a workflow that structures and supports the development process. Finally, a development process is outlined that addresses the decision-oriented nature of software development in such a manner that the necessary data is provided for decision points that guide and coordinate the development efforts. A qualitative research approach has been chosen, and the work is based on interviewing industrial experts. Several cases were set up to define the state of the practice in industrial organisations developing embedded systems for different domains. Current challenges were identified and solutions were developed and validated in case companies. The main result of the dissertation is a set of solutions integrated into the organisational workflow to support collaborative development. The main principles are that the necessary information must be provided and work and its objectives must be justified and put into the correct context. The industrial cases indicate that utilising the suggested solutions can improve collaboration among organisations and teams by helping disseminate and use the required information. Mitigating the cognitive burden speeds up the development work and reduces the effort required from developers and decision makers. In this manner, organisations may achieve better results, primarily because the produced data and results will fulfil their purposes better and provide less waste
Tiivistelmä Ohjelmistotuotanto nykymaailmassa muuttuu koko ajan haastavammaksi, kehitysprojektit ovat monimutkaisia ja hajautettuja sekä vaativat monialaista osaamista. Tiukat aikataulupaineet puolestaan tuovat mukaan oman problematiikkansa. Ohjelmistokehitys on suurelta osin kognitiivista työtä, jossa tarvitaan erilaisia taitoja ja eri alojen asiantuntijoita. Kognitiivinen työ tarkoittaa abstraktin tiedon käsittelyä ennemmin kuin fyysistä työtä. Ohjelmistojen kehittäjät törmäävät useisiin henkilökohtaiseen sekä ryhmätyöhön liittyviin haasteisiin, näistä esimerkkeinä monitahoinen tiedon käsittely, päätöksenteko ja ongelmanratkaisu. Onkin ehdotettu, että ohjelmistonkehitysprosessit ymmärrettäisiin ongelmanratkaisu- ja päätöspainotteisina prosesseina. Tässä työssä ehdotetaan, että tukeakseen ohjelmistonkehitysprosessia koko tuotteen tekemisen elinkaari on otettava huomioon ja työntekijöiden roolit ja vastuut on linkitettävä kehitysprosesseihin sekä kehitysprosessin eri vaiheisiin. Havaittuihin kognitiivisiin ongelmiin ja tarpeisiin vastataan yhteistyö- ja kommunikaatiokäytännöin, tiedonhallinnan, läpinäkyvyyden, työnkulun, ja päätöspainotteisten prosessien kautta. Tulokset kerättiin käyttäen menetelmänä laadullista tapaustutkimusta, ja työ perustuu useiden teollisten asiantuntijoiden haastatteluihin. Tutkimus toteutettiin useassa eri teollisuuden organisaatiossa. Aluksi määritettiin lähtötilanne organisaatioissa sekä kirjallisuuden perusteella, kartoitettiin ongelmat, jonka jälkeen kehitettiin tärkeimmiksi havaittuihin ongelmiin ratkaisuja. Työn tuloksena esitetään joukko ratkaisuja, jotka yhdistetään organisaation työnkulkuun. Lisäksi esitellään päätöksentekoon painottuva kehitysprosessi, jonka lähtökohtana on havainto, että vaadittavien tehtävien sekä työn tulosten on vastattava oikeaan tarpeeseen – työlle ja halutuille työn tuloksille on annettava riittävät tiedot, perustelut, päämäärä sekä oikea konteksti. Tapaustutkimukset osoittavat, että työn tulokset parantavat organisaatioiden välistä yhteistyötä helpottamalla oikean tiedon keräämistä, saamista ja käyttöä. Lisäksi ylimääräisen kognitiivisen taakan vähentäminen nopeuttaa kehitystyötä ja keventää kehittäjien ja päätöksentekijöiden työkuormaa. Täten organisaatiot voivat saavuttaa parempia työn tuloksia lähinnä siksi, että tuotettu tieto ja tulokset vastaavat paremmin tarpeisiin

Abstract:

Au cours des dernières années, en raison de la demande croissante de produits de plus enplus légers, plus petits et moins chers à l'intérieur des appareils portables, l'électronique flexible émerge sur le marché commercial comme une nouvelle génération d'électroniques. Les substrats rigides conventionnels sont remplacés par des matériaux plus minces, flexibles et à faible coût tels que papier, polymère, plastique pour la fabrication des composants et circuits. En même temps, les futurs boîtiers électroniques demandent de plus en plus de nombreux systèmes sans fil afin d'offrir de multiples services et applications (ZigBee/Z-Wave, WLAN, DECT, Bluetooth, RF4CE, 3G/4G, etc.). À cause de l'intégration d'un très grand nombre d'antennes pour satisfaire l'opération de toutes ces applications, les connectivités deviennent donc un grand défi pour les exigences de coût. C'est pourquoi on voudrait remplacer l'ensemble du système d'alimentation/d'interconnexion à la carte mère PCB par une technologie homogène, collective. Ce travail de thèse vise à développer une nouvelle technologie "verte" et faible coût dédiée à la conception et réalisation de systèmes antennaires et d'interconnexions sur les matériaux flexibles (tels que papier) à base d'encres conductrices et de procédés de fabrication additifs comme impression. Le défi scientifique est de concevoir des systèmes antennaires répartis spatialement sur les faces internes en plastique du boîtier électronique sous forme des stickers RF 3D et connectés directement à la carte PCB par une solution innovante, à faible coût pour des applications multimédia sans fil dans la gamme de fréquences de 1.8-6 GHz
In recent years, due to the growing demand for lighter, smaller and cheaper electronic products Inside portable devices, clothing and packaging materials, flexible electronics is emerging on the commercial market as a new generation of electronics. Conventional rigid substrates will be replaced by thin, flexible, low-cost materials such as paper, polymer, and plastic for the manufacturing of components and circuits. Concurrently with the powerful development of flexible electronics, the future electronic devices have drastically demanded more wireless systems in order to offer multiple services and applications (ZigBee/Z-Wave, WLAN, DECT, Bluetooth, RF4CE, 3G/4G, etc.). Because of the integration of a great number of antennas to satisfy the operation of all these applications, the connectivities thus become a big challenge for cost constraints. This is the reason why we would like to replace the entire interconnection system with the PCB mainboard by a homogeneous, collective technology.This thesis work aims at developing "green", low-cost and innovative technology devoted to the design and realization of antenna systems and interconnections on flexible materials (such as paper) based on conductive inks and additive manufacturing processes like printing. The scientific challenge lies on the design of spatially distributed antenna systems on the internal plastic sidewall of the electronics box in the form of 3D RF stickers and directly connected to the PCB mainboard by an innovative, low-cost solution for wireless multimedia applications in the frequency range of 1.8-6 GHz

У кваліфікаційній роботі на здобуття освітнього ступеня магістр проведено дослідження методів та алгоритмів прийняття оптимальних рішень у системах підтримки прийняття рішень з використанням методу аналізу ієрархій (МАІ). МАІ - методологічна є основою для рішення задач прийняття рішень у різних галузях при виборі їх альтернатив з використанням багатокритеріального рейтингового оцінювання. МАІ застосовується для підтримки прийняття рішень через ієрархічну композицію задач та проведення рейтингового оцінювання знайдених альтернативних рішень. З допомогою МАІ, або методу Сааті, в кваліфікаційній роботі виконано наступні задачі. Проведено багатокритеріальний аналіз проблеми. Виконано збір даних по проблемі. Проведена оцінка суперечливості вихідних даних та її мінімізація. Виконано синтез проблеми прийняття та ухвалення рішень. Викладено загальні задачі для організації обговорення проблеми для досягнення загального консенсусу. Проведено оцінювання вагових коефіцієнтів врахування рішень і проведено оцінювання важливості прийняття кожного фактору, досліджено вплив цих факторів на пріоритети у прийнятті рішень. Проведено оцінювання стійкості прийнятого рішення. Прийняте за допомогою МАІ рішення вважають правильним і обґрунтованим при виконанні умови для неточних даних або неточної структури ситуаційної моделі ухвалені рішення істотно не впливають на рейтинги згенерованих альтернативних рішень.

With the help of AHP, or Saati method, the following tasks were performed in the qualification work. Multicriteria analysis of the problem. Data collection on the problem has been performed. An assessment of the inconsistency of the original data and its minimization. The synthesis of the problem of decision-making and decision-making is performed. The general tasks for the organization of discussion of a problem for achievement of the general consensus are stated. Evaluation of weighting factors of decision-making was carried out and evaluation of the importance of acceptance of each factor was carried out, the influence of these factors on priorities in decision-making was investigated. An assessment of the stability of the decision was made. The decision made with the help of AHP is considered correct and reasonable if the condition for inaccurate data or inaccurate structure of the situational model is met, the decisions made do not significantly affect the ratings of generated alternative solutions.

Abstract:

Cette thèse s’inscrit dans le domaine mathématique de l’analyse des équations aux dérivées partielles non-linéaires. Plus précisément, nous avons fait ici l’étude de problèmes quasi-linéaires singuliers. Le terme "singulier" fait référence à l’intervention d’une non-linéarité qui explose au bord du domaine où ’équation est posée. La présence d’une telle singularité entraîne un manque de régularité et donc de compacité des solutions qui ne nous permet pas d’appliquer directement les méthodes classiques de l’analyse non-linéaire pour démontrer l’existence de solutions et discuter des propriétés de régularité et de comportement asymptotique de ces solutions. Pour contourner cette difficulté, nous sommes amenés à établir des estimations a priori très fines au voisinage du bord du domaine en combinant diverses méthodes : méthodes de monotonie (reliée au principe du maximum), méthodes variationnelles, argument de convexité, méthodes de point fixe et semi-discrétisation en temps. A travers, l’étude de trois problèmes-modèle faisant intervenir l’opérateur p-Laplacien, nous avons montré comment ces différentes méthodes pouvaient être mises en œuvre. Les résultats que nous avons obtenus sont décrits dans les trois chapitres de cette thèse : Dans le Chapitre I, nous avons étudié un problème d’absorption elliptique singulier. En utilisant des méthodes de sur- et sous solutions et des méthodes variationnelles, nous établissons des résultats d’existence de solutions. Par des méthodes de comparaison locale, nous démontrons également la propriété de support compact de ces solutions, pour de fortes singularités. Dans le Chapitre II, nous étudions le cas d’un système d’équations quasi-linéaires singulières. Par des arguments de point fixe et de monotonie, nous démontrons deux résultats généraux d’existence de solutions. Dans un deuxième temps, nous faisons une analyse plus détaillée de systèmes du type Gierer-Meinhardt modélisant des phénomènes biologiques. Des résultats d’unicité ainsi que des estimations précises sur le comportement des solutions sont alors obtenus. Dans le Chapitre III, nous faisons l’étude d’un problème d’absorption, parabolique singulier. Nous établissons par une méthode de semi-discrétisation en temps des résultats d’existence de solutions. Grâce à des inégalités d’énergie, nous démontrons également l’extinction en temps fini de ces solutions
This thesis deals with the mathematical field of nonlinear partial differential equations analysis. More precisely, we focus on quasilinear and singular problems. By singularity, we mean that the problems that we have considered involve a nonlinearity in the equation which blows-up near the boundary. This singular pattern gives rise to a lack of regularity and compactness that prevent the straightforward applications of classical methods in nonlinear analysis used for proving existence of solutions and for establishing the regularity properties and the asymptotic behavior of the solutions. To overcome this difficulty, we establish estimations on the precise behavior of the solutions near the boundary combining several techniques : monotonicity method (related to the maximum principle), variational method, convexity arguments, fixed point methods and semi-discretization in time. Throughout the study of three problems involving the p-Laplacian operator, we show how to apply this different methods. The three chapters of this dissertation the describes results we get :– In Chapter I, we study a singular elliptic absorption problem. By using sub- and super-solutions and variational methods, we prove the existence of the solutions. In the case of a strong singularity, by using local comparison techniques, we also prove that the compact support of the solution. In Chapter II, we study a singular elliptic system. By using fixed point and monotonicity arguments, we establish two general theorems on the existence of solution. In a second time, we more precisely analyse the Gierer-Meinhardt systems which model some biological phenomena. We prove some results about the uniqueness and the precise behavior of the solutions. In Chapter III, we study a singular parabolic absorption problem. By using a semi-discretization in time method, we establish the existence of a solution. Moreover, by using differential energy inequalities, we prove that the solution vanishes in finite time. This phenomenon is called "quenching"

Abstract:

Background: The companies of Industry 4.0 need to invest in digitalising their organizations as software is growing into a decisive manufacturing determinant. Especially in the SaaS business and the transformation to Industry 4.0, there are many small companies that are driving the transformation while competing for market share. In this context, the SaaS providers need to develop an understanding of the success of their solution. While the Information Systems Success Model by DeLone and McLean has found some application in the context of SaaS solutions, there is no specific model for the SaaS industry. Furthermore, there is the underlying need to understand which antecedents cause or influence the success of an information system. Purpose: The purpose of this study is to develop an Information Systems Success Model for Software-as-a-Service companies and to understand the antecedents and their relationships to the success of SaaS solutions from the SaaS provider’s point of view. Method: This study followed an abductive approach due to the possibility to simultaneously review existing theory and examine the empirical findings in the analysis. Furthermore, an exploratory study was conducted utilizing both quantitative and qualitative methods. The quantitative data was gathered through a standardized online survey of the customers of a SaaS provider and then analysed using Structural Equation Modelling. The qualitative data was collected through semi-structured interviews with SaaS providers, SaaS customers, and researchers of related fields and then analysed using a hermeneutic data analysis approach. The results of both methods were then triangulated to create the adapted model. Conclusion: Three antecedents of information systems success in the SaaS context were identified as part of this study. The antecedents are Management Support, User Involvement, and Trust. These antecedents can be used as levers by the SaaS provider to steer the success of their solution. Furthermore, the antecedents are integrated in a comprehensive Information Systems Success Model to measure and understand the success of SaaS solutions from the SaaS provider’s point of view.

Abstract:

With an abundant average precipitation rate, Vietnam could be considered water-reach country. Unfortunately, the non-uniform spatial and temporal distribution of rainfall, coupled with a demographic and industrial development polarized on the two major river deltas, it makes the water resources extremely vulnerable. As consequence, severe depletions of groundwater table are reported all over the country, often in the range of 1-2 m per year and more. The subsequent land subsidence is just one of the drawbacks, another being the increasing salinity of coastal aquifers as sea water level continues to rise. Under these conditions, the natural groundwater replenishment alone is not anymore able to provide for a safe water supply, different studies indicating that the groundwater exploitation in major urban agglomerations like Hanoi or Ho Chi Minh City already passed the sustainability level. The solution presented in this paper implies making use of engineered methods for enhancing the natural groundwater recharge rates by enabling better percolation rates of surface water into subsurface and thus optimizing the regional water cycle. The method known as ‘managed aquifer recharge’ (MAR) is introduced, together with general guidelines and tools for planning of MAR schemes, such as the newly web-based decision support system INOWAS_DSS

Abstract:

This licentiate thesis aims to establish the basis for scientifically understanding and supporting the cognitive processes involved in the conceptual design of resource- efficient and effective product-service systems (PSSs). The research carried out is transdisciplinary in nature and includes both prescriptive and descriptive studies. First, the cognitive nature of conceptual PSS designing is investigated. Multiple pre-experimental protocol studies in a laboratory setting are carried out to do so. The cohort of these explorative studies includes experienced industrial practitioners conceptually designing a resource-efficient PSS. These descriptive studies provide quantitative insights into the cognitive effort expended by designers on various design issues and processes during conceptual PSS designing and its potential differences to conceptual product designing. These insights form the basis for future research that can eventually shine light on this complex process with statistically significant empirical results. Second, the essence of extant prescriptive PSS design principles, methods and tools is distilled through a literature analysis and synthesis of the state of the art. Subsequently, important aspects that need to be considered during conceptual PSS designing are consolidated in the form of a PSS design schema. Third, a design navigator named lifecycle-oriented function deployment (LFD) is developed. LFD is essentially a contextual decision-making support tool, developed to guide the conceptual designing of environmentally benign PSSs. This tool informs the designers regarding the potential environmental impacts of specific design parameters of an existing offering. It subsequently guides the designers in the redesign of this existing offering into a PSS with relatively benign environmental impacts. Fourth, the effects of the two proposed prescriptions are tested empirically. True experimental protocol studies are carried out in a laboratory setting to test the effects of the prescriptive PSS design schema on the cognition of PSS designers. LFD is applied in an industrial case study using the action design research method, to support the conceptual redesign of an existing product-centric offering into an environmentally benign PSS. Environmental impacts of the PSS concepts generated using LFD are then evaluated in comparison to that of the existing offering, using simulated lifecycle assessment. A semi-structured interview is carried out to evaluate the utility and usability of LFD, with the company personnel involved in the conceptual redesign process. This licentiate thesis is an effort to effectively design the future research work of the author. This future work will aim to support and establish generalizable scientific knowledge regarding the conceptual designing of resource-efficient and effective PSSs.

Abstract:

The recognition of nature in the resolution of societal challenges has been growing in relevance. This recognition has been associated with the development of new concepts from science and policy such as natural capital, ecosystem services, green infrastructure, and more recently Nature-Based Solutions (NBS). NBS intends to address societal challenges in an effective and adaptive form providing economic, social, and environmental benefits. The overall aim of this PhD thesis is to develop an environmental and economic assessment of NBS for highly urbanised territories based on rationales and models underpinning ecosystem services, urban/landscape ecology, and life cycle thinking approaches. This combined evaluation approach would help to better understand if NBS are cost-effective or not. The aim is developed according to four specific objectives. The first objective corresponds to the characterisation of NBS in relation to urban contexts and the problematics that they can help to address or mitigate. To achieve this objective a critical review on the study of the relationship between NBS, ecosystem services (ES) and urban challenges (UC) was developed. As a main output, a graph of plausible cause-effect relationships between NBS, ES and UC is obtained. The graph represents a first step to support sustainable urban planning, moving from problems (i.e. urban challenges) to actions (i.e. NBS) to resolutions (i.e. ES). The second objective corresponds to the definition of an adequate set of biophysical and monetary assessment methods and indicators to evaluate the value of NBS in urbanised contexts. To achieve this objective, a review of existing methods on ecosystem services valuation, life cycle cost analysis and life-cycle assessment are developed. The review takes into account specific constraints such as easiness to use and availability of data. At the end, potential methods and indicators were selected, which will be later integrated in the combined assessment framework. The third objective corresponds to the design of a combined assessment framework integrating methods from life cycle assessment, landscape/urban ecology and ecosystem services that quantifies the environmental and economic value of NBS informing about the cost-effectiveness of its entire life cycle. To achieve this objective, a conceptual framework is developed. From it, a system dynamics model of ecosystem (dis)services is developed and coupled with a life cycle assessment method. The combined evaluation is tested with a relevant NBS type (i.e. urban forest) in a case study in the metropolitan area of Madrid. The fourth objective is the development of a decision support (DSS) tool that integrates the assessment framework as part of iterative design processes in urban planning and landscape design. The DSS intends to enhance the interrelation between science, policy and planning/design. To achieve this objective a user-friendly web-based prototype DSS on NBS, called NBenefit$®, is developed. The prototype DSS provides the user a simple form of quantifying the provision of multiple ES and costs over the entire life cycle (implementation, operational life, and end-of-life) of NBS. This thesis contributed to the characterisation of NBS and its environmental and economic assessment to inform urban planning and landscape design processes, allowing decisions that are more informed.
Il riconoscimento della natura nella risoluzione delle sfide sociali è diventato sempre più importante. Questo riconoscimento è stato associato allo sviluppo di nuovi concetti provenienti dalla scienza e dalla politica, come il capitale naturale, i servizi ecosistemici, le infrastrutture verdi e, più recentemente, le soluzioni basate sulla natura (NBS). NBS intende affrontare le sfide della società in una forma efficace e adattabile fornendo benefici economici, sociali e ambientali. Lo scopo di ricerca di questa tesi di dottorato è quello di sviluppare una valutazione ambientale ed economica delle NBS per territori altamente urbanizzati basata su logiche e modelli che hanno alla base i servizi ecosistemici, l'ecologia urbana e paesaggistica e degli approcci di approcio life cycle. Questo quadro di valutazione combinato aiuterebbe a capire meglio se le NBS sono costo effetive e se contribuiscono a uno sviluppo resiliente e sostenibile. Questo scopo di ricerca è sviluppato secondo quattro obiettivi specifici. Il primo obiettivo corrisponde alla caratterizzazione delle NBS in relazione ai contesti urbani e alle problematiche che possono aiutare ad affrontare o mitigare. Per raggiungere questo obiettivo è stata sviluppata una revisione critica dell letteratura sullo studio della relazione tra NBS, servizi ecosistemici (ES) e sfide urbane (UC). Come risultato principale, si ottiene un grafico delle relazioni causa-effetto plausibili tra NBS, ES ed UC. Il grafico rappresenta un primo passo per supportare la pianificazione urbana sostenibile, passando dai problemi (es. UC) alle azioni (es. NBS) alle risoluzioni (es. ES). Il secondo obiettivo corrisponde alla definizione di un set di metodi e indicatori di valutazione biofisica e monetaria adeguate per valutare il valore della NBS in contesti urbanizzati. Per raggiungere questo obiettivo, viene sviluppata una revisione dei metodi esistenti sulla valutazione dei servizi ecosistemici, l'analisi dei costi del ciclo di vita e la valutazione del ciclo di vita. La revisione tiene conto di vincoli specifici come la facilità d'uso e la disponibilità dei dati. Alla fine, sono stati selezionati potenziali metodi e indicatori, che saranno successivamente integrati nel quadro di valutazione combinato. Il terzo obiettivo corrisponde alla progettazione del quadro di valutazione combinato, integrando metodi di valutazione del ciclo di vita, ecologia paesaggistica / urbana e servizi ecosistemici che quantifica il valore ambientale ed economico della NBS informando sull'efficacia in termini di costi del suo intero ciclo di vita. Per raggiungere questo obiettivo, prima viene sviluppato un quadro concettuale. Da esso, viene sviluppato un modello di dinamica di sistemi per calcolare i servizi (e disservici) ecosistemici, il quale è interrelazionato con un metodo di valutazione life cycle. Questa valutazione combinata viene testata con un tipo di NBS pertinente (foresta urbana) in un caso di studio nell'area metropolitana di Madrid. Il quarto obiettivo è lo sviluppo di uno strumento di supporto decisionale (DSS) che integri il quadro di valutazione come parte dei processi di progettazione iterativa nella pianificazione urbana e nella progettazione del paesaggio. Il DSS intende migliorare l'interrelazione tra scienza, politica e pianificazione / progettazione. Per raggiungere questo obiettivo è stato sviluppato Nbenefit$® un prototipo di DSS online per la valutazzione NBS di facile uso. Il prototipo DSS fornisce all'utente una forma semplice per quantificare multipli ES e costi (internalizatti o no) durante l'intero ciclo di vita (implementazione, vita operativa e fine vita) del NBS. In conclusione, questa tesi ha contribuito alla caratterizzazione di NBS e alla sua valutazione ambientale ed economica per informare i processi di pianificazione urbana e progettazione del paesaggio, consentendo decisioni più informate.

Abstract:

This critical synopsis of prior work by Luca Parisi is submitted in support of a PhD by Published Work. The work focuses on deriving accurate, reliable and explainable clinical decision support systems as minimum clinically viable solutions leveraging Machine Learning (ML) and evolutionary algorithms, for the first time, to facilitate early diagnostic predictions of Parkinson's Disease and hypothermia in hospitals, as well as prognostic predictions of optimal postoperative recovery area and of chronic hepatitis. Despite the various pathological aetiologies, the underlying capability of ML-based algorithms to serve as a minimum clinically viable solution for predicting early diagnosis and prognosis has been thoroughly demonstrated. Feature selection (FS) is a proven method for increasing the performance of ML-based classifiers for several applications. Although advances in ML, such as Deep Learning (DL), have denied the usefulness of any extrinsic FS by incorporating it in their architectures, e.g., convolutional filters in convolutional neural networks, DL algorithms often lack the required explainability to be understood and interpreted by clinicians within the context of the diagnostic and prognostic tasks of interest. Their relatively complicated architectures, the hardware required for running them and the limited explainability or interpretability of their architectures, the decision-making process – although as assistive tools - driven by the algorithms’ training and predictive outcomes have hindered their application in a clinical setting. Luca Parisi’s work fills this translational research gap by harnessing the explainability of using traditional ML- and evolutionary algorithms-based FS methods for improving the performance of ML-based algorithms and devise minimum viable solutions for diagnostic and prognostic purposes. The work submitted here involves independent research work, including collaborative studies with Marianne Lyne Manaog (MedIntellego®) and Narrendar RaviChandran (University of Auckland). In particular, conciliating his work as a Senior Artificial Intelligence Engineer and volunteering commitment as the President and Research Committee Leader of a student-led association named the “University of Auckland Rehabilitative Technologies Association”, Luca Parisi decided to embark on most research works included in this synopsis to add value to society via accurate, reliable and explainable, hence clinically viable applications of AI. The key findings of these studies are: (i) ML-based FS algorithms are sufficient for devising accurate, reliable and explainable ML-based classifiers for aiding prediction of early diagnosis for Parkinson’s Disease and chronic hepatitis; (ii) evolutionary algorithms-based optimisation is a preferred method for improving the accuracy and reliability of decision support systems aimed at aiding early diagnosis of hypothermia; (iii) evolutionary algorithms-based optimisation methods enable to devise optimised ML-based classifiers for improving postoperative discharge; (iv) whilst ML-based algorithms coupled with ML based FS methods are the minimum clinically viable solution for binary classification problems, ML-based classifiers leveraging evolutionary algorithms for FS yield more accurate and reliable predictions, as reducing the search space and overlapping regions for tackling multi-class classification problems more effectively, which involve a higher number of degrees of freedom. Collectively, these findings suggest that, despite advances in ML, state-of-the-art ML algorithms, coupled with ML-based or evolutionary algorithms for FS, are enough to devise accurate, reliable and explainable decision support systems for performing both an early diagnosis and a prediction of prognosis of various pathologies.

Abstract:

In this report the design and testing of a plug and play system to run Coolfinity’s Icevolt 300 refrigerator on solar panels is discussed. Such a system will be able to provide adequate cooling for food & beverages in area’s with unreliable or no electricity available. Currently such systems are only available for small chest refrigerators, while the Icevolt 300 is a large standing commercial refrigerator with a glass door. This is ideal for shops, cafés restaurants and smaller distribution centres. The system contains a solar charge controller, a battery and an inverter. First the component specifications and required solar panels are calculated. From those calculations system components are evaluated. A custom casing is designed to fit the components. An OEM is chosen and the chosen Inverter is tested extensively. The tests show that the inverter does not have any problems starting the Icevolt 300 compressor at a reduced voltage. Many battery manufacturers are evaluated and samples from three different manufacturers are obtained and tested. Samples of one of the manufacturers match specifications and have no issues with the high start up power of the compressor. A full system test proofs that the system works, but also indicates that the original refrigerator consumption estimate was too low. This means more PV panels are needed than originally estimated. With the information from the tests a new model is build that estimates the performance more accurate. A program is written to estimate the performance and decide the PV panels required. The pilot series of the case showed a lot of improvements are needed in the case design, especially on cost. A test is prepared in Mali but no test data is obtained yet. Based on the work done it would be recommend to investigate DC direct refrigerators instead of continuing the path of PV to AC systems.
I denna rapport diskuteras design och testning av ett plug and play - system för att köra Coolfinity’s Icevolt 300 -kylskåp på solpaneler. Ett sådant system kommer att kunna tillhandahålla tillräcklig kylning för mat och dryck i områden med opålitlig eller ingen tillgänglig el. För närvarande är sådana system endast tillgängliga för små kylboxar, medan Icevolt 300 är ett stort stående kommersiellt kylskåp med en glasdörr. Detta är idealiskt för butiker, kaféer och mindre distributionscentra. Systemet innehåller en laddningsregulator för solpaneler, ett batteri och en växelriktare. Först beräknas komponentspecifikationerna och nödvändiga solpaneler. Utifrån dessa beräkningar utvärderas systemkomponenter. Ett anpassat hölje är utformat för att passa komponenterna. En OEM väljs och den valda växelriktaren testas utförligt. Testerna visar att växelriktaren inte har några problem att starta Icevolt 300 -kompressorn med reducerad spänning. Många batteritillverkare utvärderas och prover från tre olika tillverkare erhålls och testas. Prover från en av tillverkarna matchar specifikationerna och har inga problem med kompressorns höga starteffekt. Ett fullständigt systemtest bevisar att systemet fungerar, men indikerar också att den ursprungliga uppskattningen av kylförbrukningen var för låg. Det betyder att fler PV -paneler behövs än vad som ursprungligen beräknades. Med informationen från testerna byggs en ny modell som uppskattar prestandan mer exakt. Ett program skrivs för att uppskatta prestanda och bestämma vilka PV -paneler som krävs. Pilotserien för höljet visade att många förbättringar behöver göras vad beträffar höljets design, särskilt vad gäller kostnaden. Ett test förbereds i Mali men inga testdata har erhållits ännu. Baserat på det utförda arbetet skulle det rekommenderas att undersöka direkta DC -kylskåp istället för att fortsätta vägen för PV till AC-system.

Desde que foi reconhecida a importância de se planejar um turismo sustentável, tem-se buscado ferramentas adequadas para monitorá-lo nas destinações turísticas, tornando esse um dos principais desafios da academia científica de estudos do turismo na atualidade. Diante desse contexto, o desafio apresenta-se ainda maior, quando tratamos de turismo em unidades de conservação, tendo em vista que envolve um ambiente altamente sensível e comunidades em seu entorno que podem ter, no desenvolvimento dessa atividade, sua principal renda econômica. Assim, o que se propõe neste estudo é analisar a aplicabilidade e a eficiência metodológica do monitoramento que visa ao auxílio na construção da sustentabilidade do turismo, em unidades de conservação, através de um estudo de caso no Parque Estadual do Jalapão, localizado no Estado do Tocantins, Brasil. Prioriza-se a investigação de indicadores locais abordados a partir da definição estipulada pela Organização Mundial do Turismo. Os resultados alcançados demonstraram que os indicadores estudados são instrumentos a serem considerados no processo de avaliação e quantificação do turismo em um destino com semelhantes configurações ambientais, o que viabiliza a compreensão e o fortalecimento da noção de sustentabilidade. Este estudo caracteriza-se pela sua vertente interdisciplinar e teve como norteador o método dedutivo.

Abstract:

La present tesi doctoral s’ha centrat en el repte d’aconseguir, mitjançant Fabricació Additiva (FA), models per a assaig quirúrgic, sota la premissa que els equips per fer-los haurien de ser accessibles a l’àmbit hospitalari. L’objectiu és facilitar l’extensió de l’ús dels prototips com a eina de preparació d’operacions quirúrgiques, transformant la pràctica mèdica actual de la mateixa manera que en el seu moment ho van fer tecnologies com les que van facilitar l’ús de radiografies. El motiu d’utilitzar FA, en lloc de tecnologies més tradicionals, és la seva capacitat de materialitzar de forma directa les dades digitals obtingudes de l’anatomia del pacient mitjançant sistemes d’escanejat tridimensional, fent possible l’obtenció de models personalitzats. Els resultats es centren en la generació de nou coneixement sobre com aconseguir equipaments d’impressió 3D multimaterials accessibles que permetin l’obtenció de models mimètics respecte als teixits vius. Per facilitar aquesta buscada extensió de la tecnologia, s’ha focalitzat en les tecnologies de codi obert com la Fabricació per Filament Fos (FFF) i similars basades en líquids catalitzables. La recerca s’alinea dins l’activitat de desenvolupament de la FA al CIM UPC, i en aquest àmbit concret amb la col·laboració amb l’Hospital Sant Joan de Déu de Barcelona (HSJD). El primer bloc de la tesi inclou la descripció de l’estat de l’art, detallant les tecnologies existents i la seva aplicació a l’entorn mèdic. S’han establert per primer cop unes bases de caracterització dels teixits vius -sobretot tous- per donar suport a la selecció de materials que els puguin mimetitzar en un procés de FA, a efectes de millorar l’experiència d’assaig dels cirurgians. El caràcter rígid dels materials majoritàriament usats en impressió 3D els fa poc útils per simular tumors i altres referències anatòmiques. De forma successiva, es tracten paràmetres com la densitat, la viscoelasticitat, la caracterització dels materials tous a la indústria, l’estudi del mòdul elàstic de teixits tous i vasos, la duresa d’aquests, i requeriments com l’esterilització dels models. El segon bloc comença explorant la impressió 3D mitjançant FFF. Es classifiquen les variants del procés des del punt de vista de la multimaterialitat, essencial per fer models d’assaig quirúrgic, diferenciant entre solucions multibroquet i de barreja al capçal. S’ha inclòs l’estudi de materials (filaments i líquids) que serien més útils per mimetitzar teixits tous. Es constata com en els líquids, en comparació amb els filaments, la complexitat del treball en processos de FA és més elevada, i es determinen formes d’imprimir materials molt tous. Per acabar, s’exposen sis casos reals de col·laboració amb l’HJSD, una selecció d’aquells en els que el doctorand ha intervingut en els darrers anys. L’origen es troba en la dificultat de l’abordatge d’operacions de resecció de tumors infantils com el neuroblastoma, i a la iniciativa del Dr. Lucas Krauel. Finalment, el Bloc 3 té per objecte explorar nombrosos conceptes (fins a 8), activitat completada al llarg dels darrers cinc anys amb el suport dels mitjans del CIM UPC i de l’activitat associada a treballs finals d’estudis d’estudiants de la UPC, arribant-se a materialitzar equipaments experimentals per validar-los. La recerca ampla i sistemàtica al respecte fa que s’estigui més a prop de disposar d’una solució d’impressió 3D multimaterial de sobretaula. Es determina que la millor via de progrés és la de disposar d’una pluralitat de capçals independents a fi de capacitar la impressora 3D per integrar diversos conceptes estudiats, materialitzant-se una possible solució. Cloent la tesi, es planteja com seria un equipament d’impressió 3D per a models d’assaig quirúrgic, a fi de servir de base per a futurs desenvolupaments.

Finalmente, el Bloque 3 desarrolla numerosos conceptos (hasta 8), actividad completada a lo largo de los últimos cinco años con el apoyo de los medios del CIM UPC y de la actividad asociada a trabajos finales de estudios de estudiantes de la UPC, llegándose a materializar equipamientos experimentales para validarlos. La investigación amplia y sistemática al respecto hace que se esté más cerca de disponer de una solución de impresión 3D multimaterial de sobremesa. Se determina que la mejor vía de progreso es la de disponer de una pluralidad de cabezales independientes, a fin de capacitar la impresora 3D para integrar diversos conceptos estudiados, materializándose una posible solución. Para cerrar la tesis, se plantea cómo sería un equipamiento de impresión 3D para modelos de ensayo quirúrgico, a fin de servir de base para futuros desarrollos.

Abstract:

Decision support systems are currently important tools to guide the clinician’s decisions and to help on the patient’s treatments. These systems have been studied over the last decades, leading to some well-defined best practices for building new solutions. This project had the objective of building a clinical decision system with a core engine based on predefined rules, which can be customized by end-users. This work had as main motivation the treatment of diabetic inpatients and outpatients, in hospital services others than endocrinology. To keep the solution generic, the system does not depend on any specific patient data, neither on the protocols. This application follows the client-server model. based on a microservice architecture, providing a modern web user interface. The project was carried out in a close collaboration with the Hospital Center of Baixo do Vouga, resulting in a solution that can assists health professionals in the treatment of patients, reducing errors and providing a better monitoring of health care services.
Nos últimos anos, têm sido estudadas diversas metodologias para aumentar a qualidade da execução dos tratamentos oferecidos aos doentes hospitalizados. Foram igualmente desenvolvidos sistemas computacionais para auxiliar a tomada de decisões clínicas. O objetivo deste trabalho consistiu no desenvolvimento de uma aplicação web para apoiar a execução de tratamentos clínicos, seguindo regras previamente estabelecidas. Estas regras constituem as premissas base que definem o procedimento a aplicar, ou seja, a estrutura do protocolo clínico. Este trabalho teve como principal motivação o tratamento de pacientes com diabetes que são internados ou atendidos em serviços hospitalares não especializados nesta doença. Contudo, para não limitar a sua aplicação a um cenário específico, a solução foi pensada para ser flexível e ser aplicável em qualquer cenário clínico. Esta aplicação segue o modelo cliente-servidor. com base numa arquiteture de microserviços, fornecendo uma interface de utilizador web moderna. O projeto decorreu em estreita colaboração com o Centro Hospitalar do Baixo do Vouga, tendo como resultado uma solução que auxilia os profissionais de saúde no tratamento de doentes internados, reduzindo o risco de erros e aumentando o controlo e monitorização dos cuidados de saúde.

Abstract:

Earth’s biosphere is sustained by its biological diversity, which forms an intricate network of biological, physical and chemical pathways. This network has many fail-safe redundant func-tions including buffer stocks of inert biomass, huge amounts of water and the large volume of gases in the atmosphere. By contrast, manmade habitats for human space exploration are closed ecosystems that represent only a trivial fraction of Earth’s biosphere. The employment of bio-regenerative processes complemented with physical-chemical tech-nologies is thought to have numerous advantages from the perspective of redundancy and reducing resupply mass for the sustained human presence in space or on other planetary surfaces. However, the combination of bio-regenerative processes, such as plant cultivation, with physical-chemical processes to form hybrid life support systems is challenging. Such systems are a concert of many interdependencies and interacting feedback loops, which are difficult to operate in a desired range of set points. Furthermore, the complexity of such sys-tems makes them vulnerable to perturbations. Applying system dynamics modelling to study hybrid life support systems is a promising ap-proach. System dynamics is a methodology used to study the dynamic behavior of complex systems and how such systems can be defended against, or made to benefit from, the per-turbations that fall upon them. This thesis describes the development of a system dynamics model to run exploratory simulations, which can lead to new insights into the complex behav-ior of hybrid life support systems. An improved understanding of the overall system behavior also helps to develop sustainable, reliable and resilient life support architectures for future human space exploration. A set of simulations with a hybrid life support system integrated into a Mars habitat has been executed and the results show a strong impact of space greenhouses on the life support sys-tem behavior and the different matter flows. It is also evident from the simulation results that a hybrid life support system can recover from a perturbation event in most cases without a fatal mission end. Recycling urine to produce a plant nutrient solution is a novel approach in further closing loops in space life support systems. Within this thesis, a number of experiments have been executed in order to determine the effectiveness of a urine-derived nutrient solution com-pared to a standard reference solution. The results show that in principle plants can be grown with a nutrient solution made of human urine, but that the yield is lower compared to the reference solution. However, the urine-derived solution might be tuned by adding small amounts of additional nutrients to remove the imbalance of certain elements. This way the nutrient salts supplied from Earth could be reduced.

Abstract:

This dissertation formulates and develops models and solution approaches for plug-in electric vehicle (PEV) charging station installation. The models are formulated in the form of bilevel programming and stochastic programming problems, while a meta-heuristic method, genetic algorithm, and Monte Carlo bounding techniques are used to solve the problems. Demand for PEVs is increasing with the growing concerns about environment pollution, energy resources, and the economy. However, battery capacity in PEVs is still limited and represents one of the key barriers to a more widespread adoption of PEVs. It is expected that drivers who have long-distance commutes hesitate to replace their internal combustion engine vehicles with PEVs due to range anxiety. To address this concern, PEV infrastructure can be developed to provide re-fully status when they are needed. This dissertation is primarily focused on the development of mathematical models that can be used to support decisions regarding a charging station location and installation problem. The major parts of developing the models included identification of the problem, development of mathematical models in the form of bilevel and stochastic programming problems, and development of a solution approach using a meta-heuristic method. PEV parking building problem was formulated as a bilevel programming problem in order to consider interaction between transportation flow and a manager decisions, while the charging station installation problem was formulated as a stochastic programming problem in order to consider uncertainty in parameters. In order to find the best-quality solution, a genetic algorithm method was used because the formulation problems are NP-hard. In addition, the Monte Carlo bounding method was used to solve the stochastic program with continuous distributions. Managerial implications and recommendations for PEV parking building developers and managers were suggested in terms of sensitivity analysis. First, in the planning stage, the developer of the PEV parking building should consider long-term changes in future traffic flow and locate a PEV parking building closer to the node with the highest destination trip rate. Second, to attract more parking users, the operator needs to consider the walkability of walking links.

Abstract:

Cities are facing an increasing number of challenges as a result of rapid global urbanization, challenges that become even more critical in the face of population growth and climate change. Two major ones include urban sprawl and urban heating, namely the un-controlled low density, leapfrog and scattered development at the urban fringe and the higher temperatures in urban areas than in the rural surroundings. Nature-Based Solutions (NBS), solutions inspired or supported by nature, offer an innovative way to deal with these challenges and mitigate their harmful consequences. Indeed, NBS provide aesthetic services and attract residents while, at the same time, providing regulating and recreational services. Nevertheless, there is a need to show the effectiveness of NBS through evidence-based approaches and relevant indicators. The objective of this study is to provide policy-relevant visualisations of urban sprawl and urban heating indicators to provide information, communication and analysis support for decision-making around NBS establishment, taking the city of Eindhoven in the Netherlands as a case study. To this end, relevant indicators are selected from the literature and according to data available from the two disciplinary models used to assess urban sprawl (SULD) and urban heating (WRF-SUEWS) and, in turn, a user interface (UI) is developed to visualise these indicators in a user-friendly and understandable way. The UI is developed following a designimplementation- evaluation cycle, as it was tested and evaluated three times by pilot end-users as well as actual stakeholders in Eindhoven. Results show that complex model results rendered in a simple way at different scales (plot, neighbourhood and city) provide relevant information on the multiple impacts of NBS for stakeholders as well as the first step towards the apprehension of the interrelated impacts of NBS in cities. These results serve, in addition, as inputs for the development of the Systemic Decision Support Tool (SDST) of the UNaLab project (funded under the European Union Horizon 2020)
A crescente urbanização global gera inúmeros desafios às cidades, especialmente devido aos cenários de crescimento populacional e alterações climáticas. O aquecimento global e o fenómeno de urban sprawl constituem dois dos maiores desafios, nomeadamente através de uma expansão descontrolada e fragmentada na periferia urbana e em contextos rurais assim como o aumento de temperatura nas zonas urbanas. Soluções Baseadas na Natureza (SBN) apresentam-se como alternativas inovadoras que são inspiradas ou suportadas pela natureza, sendo capazes de lidar com os desafios e mitigar consequências negativas. De facto, as SBN podem ser consideradas amenidades ambientais que atraem a população para viver perto destes espaços, para além de providenciarem espaços com potencial efeito amenizante e recreativo. No entanto, existe ainda uma necessidade de comprovar a eficiência das SBS através de abordagens integradas, nomeadamente através de indicadores. Desta forma, o objetivo deste trabalho consiste em fornecer evidências sobre indicadores de aquecimento urbano e urban sprawl de forma a suportar o processo de tomada de decisão relativamente à implementação, comunicação e avaliação de SBN. Com este fim, a cidade de Eindhoven, na Holanda, é utilizada como caso de estudo. Assim sendo, indicadores existentes na literatura considerados relevantes foram selecionados e dois modelos foram utilizados para avaliar fenómenos de aquecimento urbano e de urban sprawl (WRFSUEWS e SULD), para posterior desenvolvimento de uma interface de utilizador destinada à visualização dos indicadores. Esta interface foi desenvolvida segundo um ciclo de design-implementation-evaluation, que foi testado três vezes por utilizadores piloto e partes-interessadas em Eindhoven. Os resultados mostram que o modelo utilizado reúne e fornece informação fundamental para a discussão de futuros impactos de SBN

Abstract:

Malaria is both a preventable and curable disease if treated early and appropriately. However, it is estimated that every 30 seconds a child dies of malaria in sub-Saharan Africa. The use of innovative eHealth/mHealth tools for malaria that seamlessly integrate into the workflow of healthcare workers could potentially ameliorate this problem. Successful design and development of these tools require an overarching understanding of the socio-technical context for the problems and opportunities in the application domain. A series of studies involving malaria management in the Millennium Village Project (MVP) cluster in rural Ghana were performed. A new method introduced by the author was applied to prioritize health information needs of stakeholders that have the potential to have a higher impact in solving health related problems. The result of applying this method was a group of impactful interventions for the MVP malaria program in Ghana. Findings from this study were validated with the MVP Ghana eHealth team, and after mutual agreement, an eHealth/mHealth intervention around malaria supply chain management was selected for further study. User-Centered Design (UCD) methods were adapted for use in a resource poor setting. Functional and non-functional requirements were identified. A low fidelity prototype was created and early usability inputs were collected. A high fidelity prototype was created to provide decision support to health workers through visualizations of stock levels and recommendations of quantities to order. Results from evaluation studies of the high fidelity prototype with end users suggest that they perceive the prototype as both easy to use and useful, with a potential for adoption and with a low risk of implementation. Usability problems found during the course of the study should be addressed to increase the potential of adoption. To obtain a more complete list of usability issues, both users’ and experts’ evaluations are recommended as well as the use of native and foreign test facilitators.

Abstract From the motion equation of the “bare” uniform beam (without any number of spring-mass systems and in-span support), an eigenfunction consisting of five integration constants is obtained. Where the last eigenfunction is substituted into the four compatible equations, one force-equilibrium equation and incorporating with the equation of motion for each attaching point of the spring-mass system, and the boundary equations for the two ends of the beam, a matrix equation of the form is got. The solutions of = 0 (where denotes a determinant) give the “exact” natural frequencies of the “constrained” beam (carrying any number of spring-mass systems and in-span support) and the substitution of each corresponding values of into the associated eigenfunction for each attaching points will determine the corresponding mode shapes. Since the order of is 5n+4, where n is the total number of spring-mass systems and in-span support, the “explicit” mathematical expressions for the existing approach becomes lengthy intractable if n > 2. The “numerical assembly method” introduced in this paper aims at improving the last drawback of the existing approach. The “exact” solutions in this paper refer to the numerical results obtained from the “continuum” models for the classical analytical approaches rather than from the “discretized” ones for the conventional finite element methods.
