Within the electric power industry, the average company's enterprise system - i.e. the overall system of IT related entities - is today highly complex. Technically, large organizations posses hundreds or thousands of extensively interconnected and heterogeneous single IT systems performing tasks that varies from enterprise resource planning to real-time control and monitoring of industrial processes. Moreover are these systems storing a wide variety of sometimes redundant data, and typically they are deployed on several different platforms. IT does, however, not execute in splendid isolation. Organizationally, the enterprise system embraces business processes and business units using as well as maintaining and acquiring the IT systems. The interplay between the organization and the IT systems are further determined by for instance business goals, ownership and governance structures, strategies, individual system users, documentation, and cost. Lately, Enterprise Architecture (EA) has evolved with the mission to take a holistic approach to managing the above depicted enterprise system. The discipline's presumption is that architectural models are the key to succeed in understanding and administrating enterprise systems. Compared to many other engineering disciplines, EA is quite immature in many respects. This thesis identifies and elaborates on some important aspects that to date have been overlooked to a large extent. Firstly, the lack of explicit purpose for architectural models is identified. The thesis argues that the concerns of a company's Chief Information Officer (CIO) should guide the rationale behind the development of EA models. In particular, distribution of IT related information and knowledge throughout the organization is emphasized as an important concern uncared for. Secondly, the lack of architectural theory is recognized. The thesis provides examples of how theory, or analysis procedures, could be incorporated into the Enterprise Architecture approach and hereby concretely drive the development of the architectural models. Due to the nature of enterprise systems, EA theories inevitable will be of an indicative character. Finally, in relation to the models as such, three aspects are highlighted. Firstly, the cost of collecting information from the organization to populate models is routinely neglected by the EA community. This expense should be evaluated in relation to the utility of analyses that the information can provide in terms of better informed decision making by the CIO. Secondly, models (and meta-models) must be kept consistent. And thirdly, the design of models is restricted by the limited mental capabilities of the minds of the model users. CIO concerns must consequently be easy to extract from the Enterprise Architecture models. Key words: Enterprise Architecture, Enterprise System, Chief Information Officer (CIO), Information Technology (IT) Management, Architectural Theory, Electric Power Industry

O objetivo deste trabalho é avaliar terapias para tratamento das neuropatias causadas por manipulação do feixe nervoso periférico, minimizando ou eliminando sintomas causados pela lesão. O estudo foi feito em 60 ratos machos Wistar, com a avaliação morfológica da degeneração Walleriana e da regeneração do tecido nervoso no 15º e 30º dia após o trauma. A lesão consistiu na exposição e compressão do nervo isquiático da pata direita do animal, através de três nós consecutivos com fio de sutura e distância entre eles de ~ 2mm. Três tratamentos sobre a lesão foram comparados: o uso do biomaterial 3-NERVE®, a laserterapia de baixa potência e a associação dos dois. Os resultados histológicos revelaram que o biomaterial aumentou o processo inflamatório, mas modulou a degeneração inicial, através do surgimento de células de neoformação, favorecendo a regeneração nervosa no decorrer dos trinta dias. A laserterapia foi um tratamento favorável para a parestesia porque modulou os danos do processo de degeneração inicial e estimulou o reparo do tecido desde os 15 primeiros dias. Ao atingir os 30 dias o tecido se apresentou organizado e com uma quantidade menor de tecido neoformado quando comparado com o uso do biomaterial. A associação das terapias associou as propriedades das duas terapias, pois modulou a inflamação inicial, propiciou o aumento do número de células de neoformação do tecido nervoso e favoreceu a regeneração dos feixes nervosos nas amostras de 15 e 30 dias. Conclui-se que o não tratamento dificulta ou impede a regeneração nervosa, pois qualquer uma das terapias citadas modula os eventos desencadeados pela lesão. A associação do uso da laserterapia com o 3-NERVE® mostrou melhores resultados. / Dissertação (Mestrado em Tecnologia Nuclear) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

In the modern world, the development and implementation of investment projects are becoming a competitive advantage and the key to successful development of an enterprise. The purpose of the master's thesis is to develop a methodological approach to assessing the effectiveness of investment projects in the electric power industry. The analysis was based on the study of scientific and periodical literature, the study of existing methods of evaluating the effectiveness of investment projects in enterprises. The sources of information were the regulatory legal acts, the database of publications of the Russian Science Citation Index, presented on the Elibrary resource, corporate statistics data on the subject of the research, financial reporting data and internal documents of the enterprise under study. In the course of writing the master's thesis, an approach was developed and tested to assess the effectiveness of investment projects in the power industry. As a result of approbation of the developed approach, its efficiency was justified, which made it possible to increase the accuracy of the calculated investment project performance indicators, which would further reduce the uncertainty regarding the decision on the feasibility of investing and further project implementation. / В современном мире разработка и внедрение инвестиционных проектов становятся конкурентным преимуществом и залогом успешного развития предприятия.

För att företag idag ska vara konkurrenskraftiga krävs hög kvalitet, leveransförmåga och flexibilitet. Olhager (2013) menar att ständiga förbättringar av företagsstrategier, produkter och processer är nödvändigt. Lean verktyget värdeflödesanalys kan användas för att identifiera slöserier och förbättra produktiviteten (Rahani & al-Ashraf, 2012). I denna studie undersöks det hur ett globalt industriföretag som tillverkar till kärnkraftsindustrin kan öka sin effektivitet trots regleringar från standarder och kundkrav. För att undersöka detta har observationer gjorts på företagets produktionsflöde, sedan har fyra intervjuer utförts för att få en god bild över företagets produktionsflöde och administrativa flöde samt deras nuläge. Dessutom har relevant litteratur ifrån vetenskapliga artiklar, böcker, myndigheter samlats in. Fallföretagets produkter måste uppfylla produktstandarden ASME Boiler and Pressure Vessel Code och andra krav i kundspecifikationen, som täcker tillverkning, inspektion, kvalitetssäkring, testning och frakt. För att tillverka till kärnkraftsindustrin behöver företag följa strikta kvalitetskrav samt att det förekommer omfattande mängd dokumentation och provtagningar. Företaget i denna studie har tidigare använt värdeflödesanalys för att analysera mindre delar av flödet, men företaget ser potential för bredare användning. Slutsatserna för denna studie är att standarder som ASME Boiler and Pressure Vessel Code är viktiga för kärnkraftssäkerheten. Standarden ställer höga krav för tillverkningen där det måste utföras flera kvalitetskontroller för att förhindra defekter. Detta kan göra tillverkningsprocessen mer komplex och tidskrävande i jämförelse med andra industrier. Då företaget i denna studie har ett omfattande administrativt flöde som följer längs med materialflödet är det många delar att ha kontroll på. Att använda värdeflödesanalys och analysera en större del av flödet ger en helhetsbild och möjlighet till gemensam förståelse över flödets begränsningar. För att utföra effektiva förbättringar är det viktigt att vara eniga om hur flödet ser ut och vart flaskhalsarna finns som begränsar flödet. Utifrån företaget i denna studies behov är värdeflödesanalys enligt teorin ett lämpligt verktyg att använda för att navigera i deras förbättringsarbete och öka effektiviteten. / For companies today to be competitive, high quality, delivery capability and flexibility are required. Olhager (2013) believes that continuous improvement of company strategies, products and processes becomes necessary. The Lean tool value stream mapping can be used to identify waste and improve productivity (Rahani & al-Ashraf, 2012). This study analyzes how a global industrial company that manufactures for the nuclear power industry can increase its efficiency despite regulations from standards and customer requirements. To study this, observations have been made on the company's production flow, then four interviews have been carried out to get a good picture of the company's material and administrative flow and current situation. In addition, have relevant literature from scientific articles, books, authorities been collected. The case company's products must meet the ASME Boiler and Pressure Vessel Code product standard and other customer specification requirements, covering manufacturing, inspection, quality assurance, testing and shipping. In order to manufacture for the nuclear power industry, companies need to follow strict quality requirements and there is an extensive amount of documentation and sampling. The company in this study has previously used value flow analysis to analyze smaller parts of the flow, but the company sees potential for wider use. The conclusions of this study are that standards such as the ASME Boiler and Pressure Vessel Code are important for nuclear safety. The standard places high demands on the manufacturing, where several quality controls must be carried out to prevent defects. This can make the manufacturing process more complex and time-consuming compared to other industries. As the company in this study has an extensive administrative flow that follows along with the material flow, there are many parts to have control over. Using value flow analysis and analyzing a larger part of the flow provides an overall picture and the opportunity for a common understanding of the flow's limitations. To carry out effective improvements, it is important to agree on what the flow looks like and where the bottlenecks are that limit the flow. Based on the needs of the company in this study, value flow analysis is, according to the theory, an appropriate tool to use to navigate their improvement efforts and increase efficiency.

Master of Arts / Department of Economics / Tracy M. Turner / Economic growth requires growth of energy consumption. In the second half of the twentieth century energy consumption began to outgrow its production and the United States. Consequently, we observe growing dependence of the U.S. economy on energy imports which is causing political and economic insecurity; increasing pollution and depletion of natural resources. One way to alleviate these problems is to encourage renewable electricity production. Because the electric power industry is the largest consumer of energy sources, including renewable energy, it has become one of the most frequent subjects of the regulatory policies and financial incentives aiming to stimulate renewable electricity production. One of the most promoted renewable energy policies in this industry is a renewable portfolio standard (RPS), which requires electric utilities and other retail electric providers to supply a specified amount of electricity sales from renewable energy sources. Currently 29 states and District of Columbia have the RPSs, while 7 states have goals; but only about two third of those with the RPS have certain targets to meet. To my best knowledge, there are no studies analyzing compliance with the RPSs targets or the role of penalty mechanism in the RPS design on meeting its goal. In my Master Thesis I estimate which states are in compliance with their individual RPSs goals and analyze which factors affect the probability of compliance, with the focus on the role of penalty size, and controlling for complimentary policies promoting renewable energy production. I use a fixed effects linear probability model and state level data. Results indicate that including a penalty in the RPS design significantly increases the probability that states will comply with their goals.

This study presents detailed analyses of public relations practices of the Communications Services Department, Dallas (Texas) Power & Light Company. Information sources included interviews with company personnel, company publications, and other publications. Four chapters deal with unique problems with which the electric utility industry in the United States is confronted; history and development of the electric power industry in Dallas; history and development of Dallas Power & Light Company, and organizations, functions, and operations of Communications Services Department of Dallas Power & Light Company. The study finds much strength in the department, but recommends several minor writing and clerical changes in the department's practices. It recommends further scholarly examination of public relations activities in other electric utilities.

Thesis 'Analysis of non-current tangible assets in selected entities ' deals with the non-current tangible assets from the point of view of the Czech legislation and IFRS. The theoretical part of the thesis characterises non-current tangible assets in terms of IFRS, which together with examples concern with the issues of definition and evaluation. The Czech legislation is compared with IFRS and the main differences are marked out that prevent a unified view of non-current tangible assets adjusted according to IFRS and the Czech accounting standards. The practical aspect is reflected in an empirical research that analyses non-current tangible assets in entities operating in the area of power and food industries.

s the dependence of IS/IT has grown in modern organizations, IT investments have soared in the last couple of decades. Large amounts of money are spent with the hope that the investments will generate value for the business organizations using the systems. It is hence easy to understand the needs for methods to assess the business value of IT-investments. The investment decision is basically about selecting the best IT-system or the best combination of IT-systems, i.e. the system(s) that provides the most business value in dimensions that are important business-wise. However, a problem with many of the avail-able methods is that they often fail to concretely explain what technical characteristics the IT systems(s) should have to achieve the business value desired. A complicating aspect of IT-investment evaluations is also that the evaluations usually include a high degree of un-certainty. In this thesis, an IT investment evaluation method is presented that indicatively assesses the differences in contribution to business value from IT-investment alternatives. The method provides, at a relatively low cost of investigation, indications of not only the technical differences between the IT-investment alternatives in a specific investment situation, but also an assessment of the differences in types and amounts of their business value. The presented method has been applied in a large case study at an electric power company. Furthermore, it also incorporates concepts found within Enterprise architecture (EA), particularly in how the information used in the evaluation is collected. The presented thesis is a composite thesis that, besides an introduction, includes five papers (paper A-E). Paper A presents an outline of the method as well as its application in the case study. It also presents the theoretical fundaments for the criteria used for the technical evaluation and the business value assessment including the method’s applications in relation to Enterprise architecture. The following two papers primarily present necessary steps in the development of the method. First, paper B presents the process to develop a functional reference model (used for the functional assessments in the method), including its application in the case study. Second, a breakdown of the term business value into a set of IS/IT-affected value dimension is presented in paper C. The last two papers present the final steps, i.e. the technical evaluation of the investment alternatives (paper D) and the final business value assessment (paper E). The papers include the methods to perform these analyses as well as the application of the method in the case study and the results of the case study. / QC 20100608
