Current global demands for energy resources along with continuous global population growth have placed natural environments and societies under great stress to fulfill such a need without disrupting economic and social structures. Policy and decision-making processes hold some of the most important keys to allow safe paths for societies towards energy security and safeguard of the environment. Brazil has played a lead role within renewable energy production and use during the last decades, becoming one of the world’s leading producer of sugarcane based ethanol and adapting policies to support renewable energy generation and use. Although it is true that Brazil has historic experience with managing development of renewables and its further integration into the consumer market, there is still a lot to do to impulse new technologies that could further reduce emissions, increase economic stability and social welfare. Throughout this thesis project a sustainability assessment of hydrogen production technologies in Brazil is conducted through Multi-Criteria Analysis. After defining an initial framework for decision-making, options for hydrogen production were reviewed and selected. Options were evaluated and weighted against selected sustainability indicators that fitted the established framework within a weighting matrix. An overall score was obtained after the assessment, which ranked hydrogen production techniques based on renewable energy sources in first place. Final scoring of options was analyzed and concluded that several approaches could be taken in interpreting results and their further integration into policy making. Concluding that selection of the right approach is dependent on the time scale targeted for implementation amongst other multi-disciplinary factors, the use of MCA as an evaluation tool along with overarching sustainability indicators can aid in narrowing uncertainties and providing a clear understanding of the variables surrounding the problem at hand.

The work describes the development of an adjustment algorithm that will replace today’s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system. Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two. The report describe the development of the algorithms and how they behave during simulations and tests on real robots. All three algorithms are several times faster then todays adjustment and present equivalent results at the same time. / Arbetet beskriver framtagandet av trimningsalgoritmer som ska överta dagens manuella trimning av Lead- och Lag-filter på ABB Robotics industrirobotar. Trimningen riktar sig framförallt till filterparametrarna i styrsystemet. Tre olika algoritmer har tagits fram som arvtagare till dagens manuella trimning. En av algoritmerna utgår från kriterier i dagens trimning medan en annan använder sig av optimering av känslighetsfunktionen. Den sista kan ses som en blandning av de två algoritmerna. I rapporten kan du följa algoritmernas tillkomst, hur dess resultat beter sig vid simuleringstester samt verkliga robottester. Alla tre algoritmerna är mångfaldigt snabbare än dagens trimning och presenterar samtidigt likvärdiga resultat.

Auction systems have been around for a long time now, and they are proving to be a good support instrument to promote renewable energy technologies in most parts of the world. The key feature of an auction is its design flexibility, real price discovery through competition, transparency and greater certainty for investors and policymakers to achieve high-level targets.  This thesis uses specific design elements and assessment criteria for auction systems, set out in the literature, to perform a comparative analysis of the design elements of offshore wind auctions in the UK and the Netherlands to identify best practices in auctions that promote the development of offshore wind and provide recommendations to policymakers based on previous experiences in both countries.  The analyses show that strict selection criteria and penalties help improve effectiveness and static efficiency. Seal-bid auctions with multiple rounds and fixed schedules help to reduce uncertainty for investors. Financial prequalification in the form of seabed leases ensures that developers are serious about the project and improves realization rates. Physical prequalification should be set focusing on improving the supply chain in the region, socio-political feasibility, actor diversity, etc. However, it is advisable to exclude the EIA and grid connection from the scope of the developer as it helps reduce planning risks. It is important to have ceiling prices in offshore wind auctions, but a detailed study of the technological development and market condition needs to be assessed to set the right value and have it undisclosed for better competition. Separate budgets can be set for offshore wind auctions rather than have it based on capacity or electricity generation. This helps with better planning for the auctions. Support mechanisms should be designed to ensure that generators and consumers are benefited from them. Finally, a realization period should be set for projects to ensure they are aligned with national policy targets.

The Representational State Transfer (REST) architecture style surfaced quickly to be the favorable scheme to standardize the communication for network-based hypermedia systems due to its uniform discipline. As a result, various giant web services adopted the REST architecture as their primary architectural choice for their services. Regardless of the REST style's uniform discipline, de-facto practices appeared among REST services. Consequently, numerous studies have analyzed REST services and found to a significant extent, misalignments between the theoretical aspects of REST and the practices of REST. One of the studies examined a set of services that claimed to be REST against a class of 17 design criteria that realize the principles of the REST architecture, and it found that the majority of the subject services were inconsistent in applying the REST principles. This study has followed the research mentioned earlier and examined a limited set of REST services and surveyed REST practitioners to examine their practices against the same class of the 17 design criteria to determine to what extent they are applying the 17 design criteria and analyze the statistical differences between the practices of REST services and the practices of REST practitioners. The study results show that REST services and REST practitioners applied most of the 17 design criteria. However, the study also found heterogeneous practices in REST services that go against the principles of the REST style. Furthermore, the statistical analysis results suggest a misalignment between the practices of REST services and REST practitioners in relation to the 17 design criteria.

Why this thesis is needed. This thesis is motivated by the falling school results of Swedish 15-year-olds, a lack of IT tools in Swedish schools and a call for turning the theory on formative assessment into practice.

Resource efficiency and circular economy (CE) has become increasingly relevant to the Swedish construction company NCC in connection to the plans of demolishing the current head office in Stockholm and building a new head office next to it. NCC wants to investigate how to minimize the negative sustainability implications of bringing down a commercial facility well before its life length has expired, through exploring the possibilities of integrating principles of CE in future planning‐and construction processes. This study seeks to understand how the Swedish construction company NCC could work with decision-making for CE in order to keep their materials in the loop. As the concept of CE is broad there are many options for working with its principles. However, the construction industry is relatively new to these and a list of priorities would therefore be helpful in such an initial phase, as focusing on all would be inefficient and rather daunting. Thus, this study suggests a multi-criteria decision analysis (MCDA) as a tool for decision-making and prioritizing between various approaches to CE. Together with NCC, an MCDA was performed where three different options for working with CE were analysed (Waste as Resource, Circular Design and Circular Business Models). In a focus group, 17 criteria that were relevant to NCC were developed as a basis for analysing the options. These were then defined, scored and weighted to reveal a most preferable option. The MCDA showed that the most preferable approach to CE for NCC is working with circular design, i.e. Design for Deconstruction (DfD), followed closely by measures to increase the rate of reuse and recycling of already existing construction- and demolition waste. However, the sensitivity analysis revealed that if economic criteria received a higher weight, increased reuse and recycling is the most preferable option. MCDA was deemed a helpful decision-making tool for CE principles. While the scoring and weighting is subjective and it is challenging to quantify the criteria, the strength lies in bringing a new and innovative topic on the agenda by gathering key decision-makers in focus groups to discuss and learn. A preliminary study to this thesis was conducted at NCC (Tabrizi, 2015) with the aim of conducting a survey of good examples with regard to development of commercial properties that are designed for flexibility and deconstruction during refurbishment and end‐of‐life. It showed that the challenges relate to the hesitant perception of secondary material, design and construction limitations, the need for material documentation, organization and logistics as well as creating sustainable business models. Key success factors for overcoming these challenges for NCC is working towards better communication and promotion of secondary material through information sharing, building up a knowledge base and internal targets, as well as establishing a consistent work methodology for DfD in order to move NCC towards a circular economy.

The EU has taken a major role in The Republic of Kosovo, creating a new future for the country via the EU office in Kosovo with its role in implementing EU norms in Kosovo. Kosovo is a potential candidate state for the EU and has declared its interest in becoming an EU member state.  Kosovo has implemented crucial reforms and shows commitment to advancing on its European path. Kosovo does not fulfil the general requirements for the accession based on the Copenhagen criteria yet, and there remain major internal and external hindrances to its membership. The rule of law, despite the progress made in adapting the legal framework, Kosovo needs to step up its efforts to strengthen the independence of the judiciary. Additionally, Kosovo must fight corrupted structures and organised crime by building strong and independent institutions. Furthermore, reforms in the economic area are needed to tackle Kosovo's informal economy and unemployment. Despite, the Copenhagen Criteria, the main hindrances are the five non-recognizers in the EU and the required normalization process with Serbia. Kosovo must get its independence recognized by the five non-recognizers in the EU and stabilize its relations with Serbia before focusing on the accession to the EU.

In the recent decades, therehave been frequent conflicts between groundwater waterresources and environmentally hazardous activities. Newmethodologies for aiding decision-making in groundwater impactassessment and protection areneeded and in which issues ofincreased awareness, better understanding of the groundwaterresources processes, and validation of predictive mathematicalmodels are addressed. A framework fordecision–aid, based on predictive simulations that a)predicts the environmental impacts b) provides the totaleconomical value c) visualises the impacts and the groundwaterproperties and d) describes the uncertainties in the results isproposed herein. The framework can be applied in environmentalimpact assessments, strategic environmental assessments andprotection and management of water resources. The results ofthe model are used as feedback for determining new scenarios,depending on the required uncertainties, and if the plannedactivity is sustainable, and/or fulfils the legislative andpolicy measures. This framework is applied to a particular casestudy, Nybroåsen, in the south-eastern part of Sweden,where the highway E22 is constructed through the importantglaciofluvial esker aquifer, passing the protection zone of thewater supply for the Kalmar municipality. The impacts from the new highwayand the existing road have been predicted by two-dimensionalphysically based time-variant flow and solute groundwatermodelling. The results, breakthrough curves of contaminantconcentration in wells and maps of concentration distributions,as well as travel times, flow paths, and capture zones forwells determined by particle tracking have been presented. The constructed model of theNybroåsen study area was calibrated by comparing observedand simulated groundwater levels for 15 observation wells forten years of measurements. The model has been evaluated bothgraphically and numerically and the calibration target wasfulfilled for 13 of the 15 observation wells. The model workincludes investigations of the catchment information, a waterbalance study, simulation of the groundwater recharge,consideration of the unsaturated zone by a numerical columnsimulation, and sensitivity analysis. From the sensitivity analysis ofthe flow and transport parameters, it has been shown that theuncertainties are mainly due to the hydraulic conductivity.Comparison of the derived conductivity from the steady-stateautomatic calibration and the time-variant calibration showedthat there are major differences in the derived parameters,which illustrates the importance of a time dependentcalibration over both wet and dry periods and in more than onepoint in the area of interest of the model predictions. In addition, a multi-criteriadecision analysis has been carried out for four roadalternatives (including the new highway E22) and the existingroad in the case study concerned. The multi-criteria decisionaid is applied as an illustration of how it can be used in thestudy area to identify a) interest groups of actors and theirconcerns b) ranking of alternative road scenarios according toactors’preferences and c) coalition groups of actorsi.e.groups that have similar views with regard to theroad alternatives. <b>Keywords:</b>Physically-based groundwater modelling,contamination, flow and solute transport, glaciofluvialdeposits, Nybroåsen, Sweden, and multi-criteriadecision-aid. / NR 20140805

Freight transportation changes in the region of Stockholm lead municipalities to the need of finding ways to maintain and empower their current logistics role in the area. These changes are the operation of the future freight port in Norvik near Nynäshamn, the expansion of Stockholm leading to new freight transportation networks, and the extension of the double track line southern to Västerhaninge station. Haninge municipality is willing to keep the interest of existing companies in its land alive and perhaps increase its’ attractiveness by constructing an extension of the terminal in Jordbro. But before proceeding to that step, the municipality wants to investigate whether companies are aware of these changes and furthermore if they have plans for changing their current goods transportation patterns. It is also interested in finding out the factors that companies consider as the most important when they take decisions about their goods transportation plan. That way the municipality knows what is important for companies and can adjust the supply of infrastructure to their demands. The main method used for data collection is designing and conducting a questionnaire and for data analysis it is multi-criteria analysis (MCA). The questionnaire also includes questions about the nature of the company and the current ways of goods transportation. Although the number of responders is quite low, some general conclusions could be made. There are two alternatives competing and multi-criteria analysis leads to the selection of the most suitable one. There are several limitations and assumptions which can be overcome by further future research.

Decision making processes of natural resources for sustainable development are very complex processes that contain large amounts of contradicting criteria and alternatives and/or objectives. Hence efficiency of planning and decision making is highly dependent on the structure of the decision problems. In this re-spect Multi Criteria Decision Aid (MCDA) is the most widely used method. Particularly GIS-based MCDA using the Analytical Hierarchy Process (AHP) is a well-known method in this respect. However, there are interrelationships and interdependences among problems of the real world. As a result, many spatial problems cannot be structured hierarchally because the importance of the criteria determines the importance of the alternatives, and the importance of the alternatives also determines the importance of the criteria. Analytical Network Process (ANP) based MCDA is a new planning and decision making ap-proach that allows the decision problem to be modeled considering feedbacks and interdependence among criteria. This study critically reviews GIS-based MCDA using the AHP method and the ANP based MCDA method and forwarded recommendations for future works. To attain this, practical decision making processes were used of urban form selection for a sustainable development of the Stockholm region. For this purpose literature was reviewed, separate methodologies were developed, criteria were formulated to be analyzed using GIS and SuperDecision software‟s, and finally reasonable results were achieved and separately presented to critically evaluate both the methods and the outcome. This study showed that GIS has the potential to be an important decision aid tool, that the ANP seems to give more realistic results than the GIS-based MCDA method, and that a compact scenario that over time follows already established polycentric pattern would be the best alternative urban form for a sustainable develop-ment of Greater Stockholm.
