Abstract

Relative Technical Efficiency of European Transportation Systems

Talouden kasvaessa myös tavarankuljetusmäärät kasvavat. Kuljetusjärjestelmät ja niiden sujuva toiminta on erittäin tärkeää taloudellisen kasvun kannalta tällä hetkellä, ja se tulee olemaan yhä tärkeämpää tulevaisuudessa. Tulevaisuudessa tarvitaan kokonaisvaltainen ja selkeästi tehokkaampi kuljetusjärjestelmä, mikäli tulevaisuuden kuljetusvirrat halutaan hoitaa kestävästi. Tässä opinnäytetyössäni tutkin kolmen eurooppalaisen kuljetusjärjestelmän (rautatiet, lentoliikenne ja konttiliikenne meritse) suhteellista teknistä tehokkuutta ja menetelmänä on data envelopment analysis (DEA). Vertailtaessa kuljetusjärjestelmiä löytyi suuria eroja kuljetusmuotojen välille. lentoyhtiöt suoriutuivat huomattavan tasaisesti eli tehokkaiden ja ei-tehokkaiden toimijoiden välillä ei ollut suuria eroja. Rautatiepuolella erot venyivät huomattavan suuriksi niin eri yritysten välillä kuin jopa saman yrityksen sisällä eri vuosina. Pikaisemmassa laivayhtiöiden tarkastelussa erot niiden välillä olivat lähes yhtä pieniä kuin lentoyhtiöiden välillä. Tarkasteltaessa omistajuuden vaikutusta lentoyhtiöiden toiminnassa huomattiin, että yksityisessä omistuksessa olevat yritykset olivat huomattavasti tehokkaampia matkustajien kuljettamisessa. Rahtipuolella merkittäviä eroja ei havaittu. Merkittävät korrelaatiot eri mallien välillä antoivat joitain viitteitä myös kuljetuspoliittiseen päätöksentekoon; investoinnit matkustajienkuljetuksiin raiteilla parantaisivat koko rautatiepuolen teokkuutta, mutta myös samalla lentopuolen matkustajakuljetuksen tehokkuutta.

Assessing the technical competitiveness of printing papers

This dissertation studies the technical quality assessment of a printing paper. The theoretical framework basis on the customer value hierarchy concept and the product integrity concept. The experimental part of the research was divided into two phases: Interviews of the publishers and the printers and the testing of the technical quality of selected consumer magazines and a set of selected white paper samples. The revenue coming from the advertising and the revenue coming from the copy sales arethe most important factors of efficiency of the publisher. They form the highest level in the customer value hierarchy of the publisher. A printed product is profiled according to the target group and product segment. There is no absolute level of good printed quality. It can be studied only in context of the requirements set on the printed product. Publishers quality expectations are basic elements of external product integrity. The most important elements of efficiency of the printer can be summarised to reaching high production efficiency in order toattain good profitability and competitive delivery times. Printers' factors of efficiency base on the customers expectations on the consequences in use situation in the customer value hierarchy. They form the basis of internal productintegrity. The use of purely technical testing to classify printed products according to the customers' expectations proved to be only indicative at its best. The information gathered from the interviews was documented and sorted withthe help of the QFD-technique. The technical quality of two different coated paper grades were assessed based on the customer expectations and based on the best achievable quality. When customer requirements are used for the basis of assessing the technical quality of printing papers the order from best to worst is different than when comparing the papers just based on the best achievable quality.

Modelling of North-West Russian market behavior considering technical restrictions of transmission grid

Nowadays the Finnish-Russian electric energy interaction is carried out through the back-to-back DC Vyborg substation and several power plants working synchronously with Finnish power system. Constant amount of energy flows in one direction — from Russia to Finland. But the process of electricity market development in Russian energy system makes the new possibilities of electrical cooperation available. The goal of master's thesis is to analyze the current state and possible evolution trends of North-West Russian system in relation with future possible change in power flow between Russia and Finland. The research is done by modelling the market of North-West Russia and examination of technical grid restrictions. The operational market models of North-West region of Russia for the years 2008 and 2015 were created during the research process. The description of prepared market models together with modelling results and their analysis are shown in the work. The description of power flow study process and results are also presented.

Technical Wind Energy Potential in Russia

The goal of the master's thesis is a detailed research of the technical wind energy potential in Russian Federation: the distribution of the potential all over the territory of the country and the possibility of the application of the potential for power supply of various objects. The main attention of the thesis is devoted to the assessment of wind energy resources (potential) of Russian Federation, both for the territory of country in whole and for every region. Theoretical basic wind energy concepts and the scheme of transformation of kinetic energy of a wind into electric energy by modern wind turbines are given in the work. Also the costs of energy, stimuli of development of wind-engineering and obstacles which impact the industry development are analyzed. The review of existent and projected wind power plants in Russia is carried out.

Utilization of a Time Domain Simulator in the Technical and Economic Analysis of a Wind Turbine Electric Drive Train

The amount of installed wind power has been growing exponentially during the past ten years. As wind turbines have become a significant source of electrical energy, the interactions between the turbines and the electric power network need to be studied more thoroughly than before. Especially, the behavior of the turbines in fault situations is of prime importance; simply disconnecting all wind turbines from the network during a voltage drop is no longer acceptable, since this would contribute to a total network collapse. These requirements have been a contributor to the increased role of simulations in the study and design of the electric drive train of a wind turbine. When planning a wind power investment, the selection of the site and the turbine are crucial for the economic feasibility of the installation. Economic feasibility, on the other hand, is the factor that determines whether or not investment in wind power will continue, contributing to green electricity production and reduction of emissions. In the selection of the installation site and the turbine (siting and site matching), the properties of the electric drive train of the planned turbine have so far been generally not been taken into account. Additionally, although the loss minimization of some of the individual components of the drive train has been studied, the drive train as a whole has received less attention. Furthermore, as a wind turbine will typically operate at a power level lower than the nominal most of the time, efficiency analysis in the nominal operating point is not sufficient. This doctoral dissertation attempts to combine the two aforementioned areas of interest by studying the applicability of time domain simulations in the analysis of the economicfeasibility of a wind turbine. The utilization of a general-purpose time domain simulator, otherwise applied to the study of network interactions and control systems, in the economic analysis of the wind energy conversion system is studied. The main benefits of the simulation-based method over traditional methods based on analytic calculation of losses include the ability to reuse and recombine existing models, the ability to analyze interactions between the components and subsystems in the electric drive train (something which is impossible when considering different subsystems as independent blocks, as is commonly done in theanalytical calculation of efficiencies), the ability to analyze in a rather straightforward manner the effect of selections other than physical components, for example control algorithms, and the ability to verify assumptions of the effects of a particular design change on the efficiency of the whole system. Based on the work, it can be concluded that differences between two configurations can be seen in the economic performance with only minor modifications to the simulation models used in the network interaction and control method study. This eliminates the need ofdeveloping analytic expressions for losses and enables the study of the system as a whole instead of modeling it as series connection of independent blocks with no lossinterdependencies. Three example cases (site matching, component selection, control principle selection) are provided to illustrate the usage of the approach and analyze its performance.

Finnair Technical Procurement’s Processes and Service Quality

As primary objective, this thesis examines Finnair Technical Procurement’s service quality with its underlying process. As an internal unit, Technical Procurement serves as a link between external suppliers and internal customers. It is argued that external service quality requires a certain quality level within an organization. At the same time, aircraft maintenance business is subject to economic restraints. Therefore, a methodology was developed with a modified House of Quality that assists management in analyzing and evaluating Technical Procurement’s service level and connected process steps. It could be shown that qualitative and quantitative objectives do not exclude each other per se.

Innovations of ageing and societal transition : Dynamics of change of the socio-technical regime of ageing

The purpose of this dissertation is to examine the dynamics of the socio-technical system in the field of ageing. The study stems from the notion that the ageing of the population as a powerful megatrend has wide societal effects, and is not just a matter for the social and health sector. The central topic in the study is change: not only the age structures and structures of society are changing, but also at the same time there is constant development, for instance, in technologies, infrastructures and cultural perceptions. The changing concept of innovation has widened the understanding of innovations related to ageing from medical and assistive technological innovations to service and social innovations, as well as systemic innovations at different levels, which means the intertwined and co-evolutionary change in technologies, structures, services and thinking models. By the same token, the perceptions of older people and old age are becoming more multi-faceted: old age is no longer equated to illnesses and decline, but visions of active ageing and a third age have emerged, which are framed by choices, opportunities, resources and consumption in later life. The research task in this study is to open up the processes and mechanisms of change in the field of ageing, which are studied as a complex, multi-level and interrelated socio-technical system. The question is about co-effective elements consisting of macro-level landscape changes, the existing socio-technical regime (the rule system, practices and structures) and bottom-up niche-innovations. Societal transitions do not account for the things inside the regime alone, or for the long-term changes in the landscape, nor for the radical innovations, but for the interplay between all these levels. The research problem is studied through five research articles, which offer micro-level case studies to macro-level phenomenon. Each of the articles focus on different aspects related to ageing and change, and utilise various datasets. The framework of this study leans on the studies of socio-technical systems and multi-level perspective on transitions mainly developed by Frank Geels. Essential factors in transition from one socio-technological regime to another are the co-evolutionary processes between landscape changes, regime level and experimental niches. Landscape level changes, like the ageing of the population, destabilise the regime in the forms of coming pressures. This destabilization offers windows for opportunity to niche-innovations outside or at fringe of the regime, which, through their breakthrough, accelerate the transition process. However, the change is not easy because of various kinds of lock-ins and inertia, which tend to maintain the stability of the regime. In this dissertation, a constructionist approach of society is applied leaning mainly to the ideas of Anthony Giddens’ theory of structuration, with the dual nature of structures. The change is taking place in the interplay between actors and structures: structures shape people’s practices, but at the same time these practices constitute and reproduce social systems. Technology and other material aspects, as part of socio-technical systems, and the use of them, also take part in the structuration process. The findings of the study point out that co-evolutionary and co-effective relationships between economic, cultural, technological and institutional fields, as well as relationships between landscape changes, changes in the local and regime-level practices and rule systems, are a very complex and multi-level dynamic socio-technical phenomenon. At the landscape level of ageing, which creates the pressures and triggers to the regime change, there are three remarkable megatrends: demographic change, changes in the global economy and the development of technologies. These exert pressures to the socio-technical regime, which as a rule system is experiencing changes in the form of new markets and consumer habits, new ways of perceiving ageing, new models of organising the health care and other services and as new ways of considering innovation and innovativeness. There are also inner dynamics in the relationships between these aspects within the regime. These are interrelated and coconstructed: the prevailing perceptions of ageing and innovation, for instance, reflect the ageing policies, innovation policies, societal structures, organising models, technology and scientific discussion, and vice versa. Technology is part of the inner dynamics of the sociotechnological regime. Physical properties of the artefacts set limitations and opportunities with regard to their functions and uses. The use of and discussion about technology, contributes producing and reproducing the perceptions of old age. For societal transition, micro-level changes are also needed, in form of niche-innovations, for instance new services, organisational models or new technologies, Regimes, as stabilitystriven systems, tend to generate incremental innovations, but radically new innovations are generated in experimental niches protected from ‘normal’ market selection. The windows of opportunity for radical novelties may be opened if the circumstances are favourable for instance by tensions in the socio-technical regime affected by landscape level changes. This dissertation indicates that a change is taking place, firstly, in the dynamic interactionbetween levels, as a result of purposive action and governance to some extent. Breaking the inertia and using the window of opportunity for change and innovation offered by dynamics between levels, presupposes the actors’ special capabilities and actions such as dynamic capabilities and distance management. Secondly, the change is taking place the socio-technological negotiations inside the regime: interaction between technological and social, which is embodied in the use of technology. The use of technology includes small-level contextual scripts that also participate in forming broader societal scripts (for instance defining old age at the society level), which in their turn affect the formation of policies for innovation and ageing. Thirdly, the change is taking place by the means of active formation of the multi-actor innovation networks, where the role of distance management is crucial to facilitate the communication between actors coming from different backgrounds as well as to help the niches born outside the regime to utilise the window of opportunity offered by regime destabilisation. This dissertation has both theoretical and practical contributions. This study participates in the discussion of action-oriented view on transition by opening up of the socio-technological, coevolutionary processes of the multi-faceted phenomenon of ageing, which has lacked systematic analyses. The focus of this study, however, is not on the large-scale coordination and governance, but rather on opening up the incremental elements and structuration processes, which contribute to the transition little by little, and which can be affected to. This increases the practical importance of this dissertation, by highlighting the importance of very tiny, everyday elements in the change processes in the long run.

Predicting Market Crashes: An Examination of the Performance of Macroeconomic Indicators and Technical Analysis

The purpose of this study is to examine macroeconomic indicators‟ and technical analysis‟ ability to signal market crashes. Indicators examined were Yield Spread, The Purchasing Managers Index and the Consumer Confidence Index. Technical Analysis indicators were moving average, Moving Average Convergence-Divergence and Relative Strength Index. We studied if commonly used macroeconomic indicators can be used as a warning system for a stock market crashes as well. The hypothesis is that the signals of recession can be used as signals of stock market crash and that way a basis for a hedging strategy. The data is collected from the U.S. markets from the years 1983-2010. Empirical studies show that macroeconomic indicators have been able to explain the future GDP development in the U.S. in research period and they were statistically significant. A hedging strategy that combined the signals of yield spread and Consumer Confidence Index gave most useful results as a basis of a hedging strategy in selected time period. It was able to outperform buy-and-hold strategy as well as all of the technical indicator based hedging strategies.

Sivistyksestä sivilisaatioon. Kulttuurikäsitys J. V. Snellmanin historiallisessa ajattelussa

From Bildung to Civilisation. Conception of Culture in J. V. Snellman’s Historical Thinking The research explores Johan Vilhelm Snellman’s (1806–1881) conception of culture in the context of his historical thinking. Snellman was a Finnish, Swedish-speaking journalist, teacher and thinker, who held a central position in the Finnish national discourse during the nineteenth century. He has been considered as one of the leading theorists of a Finnish nation, writing widely about the themes such as the advancement of the national education, Finnish language and culture. Snellman is already a widely studied person in Finnish intellectual history, often characterised as a follower of G. W. F. Hegel’s philosophical system. My own research introduces a new kind of approach on Snellman’s texts, emphasising the conceptual level of his thought. With this approach, my aim is to broaden the Finnish research tradition on conceptual history. I consider my study as a cultural history of concepts, belonging also to the field of intellectual history. My focus is on one hand on the close reading of Snellman’s texts and on the other hand on contextualising his texts to the European intellectual tradition of the time. A key concept of Snellman’s theoretical thinking is his concept of bildning, which can be considered as a Swedish counterpart of the German concept of Bildung. The Swedish word incorporated all the main elements of the German concept. It could mean education or the so-called high culture, but most fundamentally it was about the self-formation of the individual. This is also the context in which Snellman’s concept of bildning has often been interpreted. In the study, I use the concept of bildning as a starting point of my research but I broaden my focus on the cognate concepts such as culture (kultur), spirit (anda) and civilisation. The purpose of my study is thus to illustrate how Snellman used and modified these concepts and from these observations to draw a conclusion about the nature of his conception of culture. Snellman was an early Finnish philosopher of history but also interested in the practice of the writing of history. He did not write any historical presentations himself but followed the publications in the field of history and introduced European historical writing to the Finnish, Swedish-speaking reading audience in his newspapers. The primary source material consists of different types of Snellman’s texts, including philosophical writings, lecture material, newspaper articles and private letters. I’m reading Snellman’s texts in the context of other texts produced both by his Finnish predecessors and contemporaries and by Swedish, German and French writers. Snellman’s principal philosophical works, Versuch einer spekulativen Entwicklung der Idee der Persönlichkeit (1841) and Läran om staten (1842), were both written abroad. Both of the works were contributions to contemporary debates on the international level, especially in Germany and Sweden. During the 1840s and 1850s Snellman had two newspapers of his own, Saima and Litteraturblad, which were directed towards the Swedish-speaking educated class. Both of the newspapers were very popular and their circulations were among the largest of their day in Finland. The topics of his articles and reviews covered literature, poetry, philosophy and education as well as issues concerning the economic, industrial and technical development in Finland. In his newspapers Snellman not only brought forth his own ideas but also spread the knowledge of European events and ideas to his readers. He followed very carefully the cultural and political situation in Western Europe. He also followed European magazines and newspapers and was well acquainted with German, French and also English literature – and of course Swedish literature to with which he had the closest ties. In his newspapers Snellman wrote countless number of literary reviews and critics, introducing his readers to European literature. The study consists of three main chapters in which I explore my research question in three different, yet overlapping contexts. In the first of these chapters, I analyse Snellman’n theoretical thinking and his concepts of bildning, kultur, anda and civilisation in the context of earlier cultural discourse in Finland as well as the tradition of German idealistic philosophy and neo-humanism. With the Finnish cultural discourse I refer to the early cultural discussion in Finland, which emerged after the year 1809, when Finland became an autonomous entity of its own as a Grand Duchy of Russia. Scholars of the Academy of Turku opened a discussion on the themes such as the state of national consciousness, the need for national education and the development of the Finnish language as a national language of Finland. Many of these academics were also Snellman’s teachers in the early years of his academic career and Snellman clearly formulated his own ideas in the footsteps of these Finnish predecessors. In his theoretical thinking Snellman was a collectivist; according to him an individual should always be understood in connection with the society, its values and manners, as well as to the traditions of a culture where an individual belongs to. In his philosophy of the human spirit Snellman was in many ways a Hegelian but his notion of education or ‘bildning’ includes also elements that connect him with the wider tradition of German intellectual history, namely the neo-humanist tradition and, at least to some extent, to the terminology of J. G. Herder or J. G. Fichte, for example. In this chapter, I also explore Snellman’s theory of history. In his historical thinking Snellman was an idealist, believing in the historical development of the human spirit (Geist in German language). One can characterise his theory of history by stating that it is a mixture of a Hegelian triumph of the spirit and Herderian emphasis on humanity (Humanität) and the relative nature of ‘Bildung’. For Snellman, the process of ‘bildning’ or ‘Bildung’ is being realised in historical development through the actions of human beings. Snellman believed in the historical development of the human civilization. Still Snellman himself considered that he had abandoned Hegel’s idea about the process of world history. Snellman – rightly or wrongly – criticised Hegel of emphasising the universal end of history (the realisation of the freedom of spirit) at the expense of the historical plurality and the freedom of each historical era. Snellman accused Hegel of neglecting the value and independency of different historical cultures and periods by imposing the abstract norm, the fulfilment of the freedom of spirit, as the ultimate goal of history. The historicist in Snellman believed in the individuality of each historical period; each historical era or culture had values, traditions and modes of thought of its own. This historicist in Snellman could not accept the talk about one measure or the end of history. On the other hand Snellman was also a universalist. He believed that mankind had a common task and that task was the development of ‘Bildung’, freedom or humanity. The second main chapter consists of two parts. In the first part, I explore the Finnish nationalistic discourse from the cultural point of view by analysing the notions such as a nation, national spirit or national language and showing how Snellman formulated his own ideas in a dialogic situation, participating in the Finnish discourse but also reacting to international discussions on the themes of the nation and nationality. For Snellman nationality was to a great extent the collective knowledge and customs or practices of the nation. Snellman stated that nationality is to be considered as a form of ‘bildning’. This could be seen not simply as affection for the fatherland but also for the mental identity of the nation, its ways of thinking, its practices, national language, customs and laws, the history of the nation. The simplest definition of nationality that Snellman gives is that nationality is the social life of the people. In the second part of the chapter I exam Snellman’s historical thinking and his understanding about historical development, interaction between different nations and cultures in the course of history, as well as the question of historical change; how do cultures or civilisations develop and who are the creators of culture? Snellman did not believe in one dominating culture but understood the course of history as a dialogue between different cultures. On the other hand, his views are very Eurocentric – here he follows the ideas of Hegel or for example the French historian François Guizot – for Snellman Europe represented the virtue of pluralism; in Europe one could see the diversity of cultures which, on the other hand, were fundamentally based on a common Christian tradition. In the third main chapter, my focus is on the writing of history, more precisely on Snellman’s ideas on the nature of history as a science and on the proper way of writing historical presentations. Snellman wrote critics on the works of history and introduced his readers to the writing of history especially in France, Sweden and German-speaking area – in some extend also in Britain. Snellman’s collectivistic view becomes evident also in his reviews on historical writing. For Snellman history was not about the actions of the states and their heads, nor about the records of ruling families and battles fought. He repeatedly stressed that history is a discipline that seeks to provide a total view of a phenomenon. A historian should not only collect information on historical events, since this information touches only the surface of a certain epoch or civilisation; he has to understand an epoch as totality. This required an understanding about the major contours in history, connections between civilisations and an awareness of significant turning points in historical development. In addition, it required a holistic understanding about a certain culture or historical era, including also the so-called inner life of a specific nation, a common people and their ways of life. Snellman wrote explicitly about ‘cultural history’ in his texts, referring to this kind of broad understanding of a society. In historical writing Snellman found this kind of broader view from the works of the French historians such as François Guizot and Jules Michelet. In all of these chapters, I elaborate the conceptual dimension of Snellman’s historical thinking. In my study I argue that Snellman not only adopted the German concepts of Bildung or Kultur in his own thinking but also developed the Swedish concepts in a way that include personal and innovative aspects. Snellman’s concept of bildning is not only a translation from ‘Bildung’ but he uses the Swedish concept in a versatile way that includes both the moral aspect of human development and social dimension of a human life. Along with ‘bildning’ Snellman used also the terms ‘kultur’ and ‘civilisation’ when referring to the totality of a certain nation or historical era, including both the so-called high culture (arts, science, religion) and the modes of thought as well as ways of life of the people as a whole. Unlike many of his Finnish contemporaries, Snellman did not use civilisation as a negative concept, lacking the moral essence of German term ‘Bildung’ or ‘Kultur’. Instead, for Snellman civilisation was a neutral term and here he comes close to the French tradition of using the term. In the study I argue that Snellman’s conception of culture in fact includes a synthesis of the German tradition of ‘Bildung’ and the French tradition of ‘civilisation’.

Identification of research trends in the field of separation processes. Application of epidemiological model, citation analysis, text mining, and technical analysis of the financial markets

Choice of industrial development options and the relevant allocation of the research funds become more and more difficult because of the increasing R&D costs and pressure for shorter development period. Forecast of the research progress is based on the analysis of the publications activity in the field of interest as well as on the dynamics of its change. Moreover, allocation of funds is hindered by exponential growth in the number of publications and patents. Thematic clusters become more and more difficult to identify, and their evolution hard to follow. The existing approaches of research field structuring and identification of its development are very limited. They do not identify the thematic clusters with adequate precision while the identified trends are often ambiguous. Therefore, there is a clear need to develop methods and tools, which are able to identify developing fields of research. The main objective of this Thesis is to develop tools and methods helping in the identification of the promising research topics in the field of separation processes. Two structuring methods as well as three approaches for identification of the development trends have been proposed. The proposed methods have been applied to the analysis of the research on distillation and filtration. The results show that the developed methods are universal and could be used to study of the various fields of research. The identified thematic clusters and the forecasted trends of their development have been confirmed in almost all tested cases. It proves the universality of the proposed methods. The results allow for identification of the fast-growing scientific fields as well as the topics characterized by stagnant or diminishing research activity.
