Public and Private Sector Decision Makers Within the Rail Baltica Growth Corridor

Transport volumes have increased and will continue to increase in European Union. Even though the growth has not been equal between different transport modes. Most of the growth has been faced on road transport. European Union aims to balance the unbalanced market shares between the modes by gaining and supporting the competitiveness of railway and waterway transport. In EU railway transportation is seen as solution to increase safety in traffic and decrease the environmental impacts of transportation. The aim of this research is to figure out how it is possible to decrease the environmental impacts by the technology already in use. Main focus of this research is in intermodality and combining the road and railway transportation. This study aims also to figure out demands and expectations towards new Rail Baltica railway route connecting Tallinn and Berlin. The research is conducted by performing a literature review about decreasing environmental impacts and combining road and rail transport. Another viewpoint is taken from the possible effects of tourism to the passenger transport on rails. Knowledge gained by literature review is deepened by additional internet questionnaire study and expert interview study. In decreasing the environmental impacts of transportation electric trains are definitely the best option providing that the electricity is generated from renewable or carbon dioxide free sources. Decrease of environmental impacts has been reached also with acceptance of larger road transport vehicles. According to interviewed passenger transport experts, the whole route from Tallinn to Berlin may not be convenient to be used in passenger transport, just because the route is too long.. In EU freight is transported mainly with semi-trailer combinations, and that is why it could be logical if huckepack trains would be used on Rail Baltica. Huckepack train allows semi-trailers to be transported on rails with time efficient loading-unloading process. Overall, Rail Baltica project is experienced as a future-oriented one and new railway alignment is seen as great alternative option for transport modes using fossil fuels.

Modeling and Control of the Power Conversion Unit in a Solid Oxide Fuel Cell Environment

In this doctoral thesis, a power conversion unit for a 10 kWsolid oxide fuel cell is modeled, and a suitable control system is designed. The need for research was identified based on an observation that there was no information available about the characteristics of the solid oxide fuel cell from the perspective of power electronics and the control system, and suitable control methods had not previously been studied in the literature. In addition, because of the digital implementation of the control system, the inherent characteristics of the digital system had to be taken into account in the characteristics of the solid oxide fuel cell (SOFC). The characteristics of the solid oxide fuel cell as well the methods for the modeling and control of the DC/DC converter and the grid converter are studied by a literature survey. Based on the survey, the characteristics of the SOFC as an electrical power source are identified, and a solution to the interfacing of the SOFC in distributed generation is proposed. A mathematical model of the power conversion unit is provided, and the control design for the DC/DC converter and the grid converter is made based on the proposed interfacing solution. The limit cycling phenomenon is identified as a source of low-frequency current ripple, which is found to be insignificant when connected to a grid-tied converter. A method to mitigate a second harmonic originating from the grid interface is proposed, and practical considerations of the operation with the solid oxide fuel cell plant are presented. At the theoretical level, the thesis discusses and summarizes the methods to successfully derive a model for a DC/DC converter, a grid converter, and a power conversion unit. The results of this doctoral thesis can also be used in other applications, and the models and methods can be adopted to similar applications such as photovoltaic systems. When comparing the results with the objectives of the doctoral thesis, we may conclude that the objectives set for the work are met. In this doctoral thesis, theoretical and practical guidelines are presented for the successful control design to connect a SOFC-based distributed generation plant to the utility grid.

Service innovation development and knowledge integration practices - a comparative case study on KIBS sector

Academic research on services and innovations on services has significantly grown during recent years. So far research concerning management of knowledge intensive work on service development activities is very limited. The objective of this study was to examine knowledge integration practices that support service innovation development and to the best of knowledge such studies have not been previously published in academic literature. In the theoretical part of the study a review of state‐of‐the‐art literature was conducted, research gap was indicated and a framework for analysis was built. In the empirical part an explorative comparative multi‐case study was carried out in KIBS sector. Four companies were selected and four service development projects were inspected. The service development activities and knowledge integration practices were identified. The cases were carefully compared and results formed. The empirical results indicated that service innovation development is partly linear and partly incremental flow of activities where knowledge integration practices have important role supporting the planning and execution of tasks. Knowledge integration practices supporting planning and workshops are close interaction, interpretation, project planning and sequencing of work tasks. The identified knowledge integration practices supporting building service solution were careful role and competence management, routines and common knowledge. The main implication is that to manage knowledge intensive service innovation development a firm should carefully develop and choose relevant knowledge integration practices to support the service development activities.

Limestone Reactions in a Fluidized Bed Heat Exchanger of an Oxy-fuel Circulating Fluidized Bed Boiler

Oxy-fuel combustion in a circulating fluidized bed (CFB) boiler appears to be a promising option for capturing CO2 in power plants. Oxy-fuel combustion is based on burning of fuel in the mixture of oxygen and re-circulated flue gas instead of air. Limestone (CaCO3) is typically used for capturing of SO2 in CFB boilers where limestone calcines to calcium oxide (CaO). Because of high CO2 concentration in oxy-fuel combustion, calcination reaction may be hindered or carbonation, the reverse reaction of calcination, may occur. Carbonation of CaO particles can cause problems especially in the circulation loop of a CFB boiler where temperature level is lower than in the furnace. The aim of the thesis was to examine carbonation of CaO in a fluidized bed heat exchanger of a CFB boiler featuring oxy-fuel combustion. The calculations and analyzing were based on measurement data from an oxy-fuel pilot plant and on 0-dimensional (0D) gas balance of a fluidized bed heat exchanger. Additionally, the objective was to develop a 1-dimensional (1D) model of a fluidized bed heat exchanger by searching a suitable pre-exponential factor for a carbonation rate constant. On the basis of gas measurement data and the 0D gas balance, it was found that the amount of fluidization gas decreased as it flew through the fluidized bed heat exchanger. Most likely the reason for this was carbonation of CaO. It was discovered that temperature has a promoting effect on the reaction rate of carbonation. With the 1D model, a suitable pre-exponential factor for the equation of carbonation rate constant was found. However, during measurements there were several uncertainties, and in the calculations plenty of assumptions were made. Besides, the temperature level in the fluidized bed heat exchanger was relatively low during the measurements. Carbonation should be considered when fluidized bed heat exchangers and the capacity of related fans are designed for a CFB boiler with oxy-fuel combustion.

Logistics of North-West Russia and Rail Baltica: Standpoints of Private Sector

The main aims of the present report are to describe the current state of railway transport in Russia, and to gather standpoints of Russian private transportation logistics sector towards the development of new railway connection called Rail Baltica Growth Corridor, connecting North-West Russia with Germany through the Baltic States and Poland. North-West Russia plays important role not only in Russian logistics, but also wider European markets as in container sea ports handling is approx. 2.5 mill. TEU p.a. and handling volume in all terminals is above 190 million tons p.a. The whole transportation logistics sector is shortly described as an operational environment for railways – this is done through technical and economic angles. Transportation development is always going in line with economics of the country, so the analysis on economical development is also presented. Logistics integration of the country is strongly influenced by its engagement in the international trade. Although, raw material handling at sea ports and container transports (imports) are blossoming, domestic transportation market is barely growing (in long-term perspective). Thus, recent entrance of Russia into World Trade Organization (WTO) is analyzed theme in this research, as the WTO is an important regulator of the foreign trade and enabler of volume growth in foreign trade related transportation logistics. However, WTO membership can influence negatively the development of Russia’s own industry and its volumes (these have been uncompetitive in global markets for decades). Data gathering in empirical part was accomplished by semi-structured case study interviews among North-West Russian logistics sector actors (private). These were conducted during years 2012-2013, and research compiles findings out of ten case company interviews. Although, there was no sea port involved in the study, most of the interviewed companies relied in European Logistics within significant parts in short sea shipping and truck combined transportation chains (in Russian part also using railways). As the results of the study, it could be concluded that Rail Baltica is seen as possible transport corridor in most of the interviewed companies, if there is enough cargo available. However, interviewees are a bit sceptical, because major and large-scale infrastructural improvements are needed. Delivery time, frequency and price level are three main factors influencing the attractiveness of Rail Baltica route. Price level is the most important feature, but if RB can offer other advantages such as higher frequency, shorter lead times or more developed set of value-added services, then some flexibility is possible for the price level. Environmental issues are not the main criteria of today, but are recognized and discussed among customers. Great uncertainty exists among respondents e.g. on forthcoming sulphur oxide ban on Baltic Sea shipping (whether or not it is going to be implemented in Russia). Rather surprisingly, transportation routes to Eastern Europe and Mediterranean area are having higher value and price space than those to Germany/Central Europe. Border crossing operations (traction monopoly at rails and customs), gauge widths as well as unclear decision-making processes (in Russia), are named as hindering factors. Performance standards for European connected logistics among Russian logistics sector representatives are less demanding as compared to neighbourhood countries belonging to EU.

Exploring the value creation in service ecosystem context: the case of the information technology sector

This thesis examines customer value creation in a service ecosystem context. The objective of this thesis is to develop a comprehensive view of value creation processes in a service ecosystem context and an understanding on the roles of the stakeholders involved in these processes, focusing on the information technology industry. The novelty of the two central concepts of this thesis, systemic customer value and service ecosystem, as well as the gap in the literature of empirical research on value creation in an ecosystem-level, opened an interesting research topic. The empirical study is conducted as a single case analysis, utilizing Group Decision Support System (GDSS) and also Analytic Hierarchy Process (AHP). The findings suggest that customer value is created by a complex combination of interactions among different actors of the ecosystem. Thus, value is not created by a single offering directed to the customer, but by an integration of services from different parts of the ecosystem as well as the active participation of customer in this process.

Mapping the Value Network Potential in Cross-sector Collaboration: Case welfare Services for Elderly in Finland

Value network has been studied greatly in the academic research, but a tool for value network mapping is missing. The objective of this study was to design a tool (process) for value network mapping in cross-sector collaboration. Furthermore, the study addressed a future perspective of collaboration, aiming to map the value network potential. During the study was investigated and pondered how to get the full potential of collaboration, by creating new value in collaboration process. These actions are parts of mapping process proposed in the study. The implementation and testing of the mapping process were realized through a case study of cross-sector collaboration in welfare services for elderly in the Eastern Finland. Key representatives in elderly care from public, private and third sectors were interviewed and a workshop with experts from every sector was also conducted in this regard. The value network mapping process designed in this study consists of specific steps that help managers and experts to understand how to get a complex value network map and how to enhance it. Furthermore, it make easier the understanding of how new value can be created in collaboration process. The map can be used in order to motivate participants to be engaged with responsibility in collaboration and to be fully committed in their interactions. It can be also used as a motivator tool for those organizations that intend to engage in collaboration process. Additionally, value network map is a starting point in many value network analyses. Furthermore, the enhanced value network map can be used as a performance measurement tool in cross-sector collaboration.

Accounting for competition, governance and accountability during institutional change in not-for-profit and public sector organisations

Purpose The aim of this thesis1 is to analyse theoretically how institutionalisation of competitive tendering2, governance and budgetary policies cannot be taken for granted to lead to accountability among institutional actors3. The nature of an institutionalised management accounting policy, its relevance as a source of power in organisational decision making, and in negotiating inter-organisational relationships, are also analysed. Practical motivation The practical motivation of the thesis is to show how practitioners and policy makers can institutionalise changes which improve the power of management accounting and control systems4 as a mechanism of accountability among institutional actors and in negotiating relationships with other organisations. Theoretical motivation and conceptual approach The theoretical motivation of the thesis is to extend the institutional framework of management accounting change proposed by Burns and Scapens (2000) by using the theories of critical realism, communicative action, negotiated order and the framework of circuits of power. The Burns and Scapens framework needs further theorisation to analyse the relationship between the institutionalisation of management accounting and accountability; and the relevance of management accounting information in negotiating in inter-organisational relationships. Methodology and field studies Field research took place in public and not-for-profit health care organisations and a municipality in Finland from 2008 to 2013. Data were gathered by document analysis, interviews, participation in meetings and observations. Findings The findings are explained in four different essays that show that institutionalisation of competitive tendering, governance and budgetary policies cannot be taken for granted to lead to accountability among institutional actors. The ways by which institutional actors think and act can be influenced by other institutional mechanisms, such as inter-organisational circuits of power and intraorganisational governance policies, independent of the institutional change process. The relevance of institutionalised management accounting policies in negotiating relationships between two or more organisations depends on processes and contexts through which institutional actors use management accounting information as a tool of communication, mutual understanding and power. Research limitations / implications The theoretical framework used can be applied validly in other studies. The empirical findings cannot be generalised directly to other organisations than the organisations analysed. Practical implications Competitive tendering and budgetary policies can be institutionalised to shape actions of institutional actors within an organisation. To lead to accountability, practitioners and policy makers should implement governance policies that increase the use of management accounting information in institutional actors’ thinking, actions and responsibility for their actions. To reach a negotiated order between organisations, institutionalised management accounting policies should be used as one of the tools of communication aiming to reach mutual agreement among institutional actors.

Fate of fuel-bound nitrogen and sulfur in biomass-fired Industrial boilers

Användning av biomassa som energikälla för produktion av el och värme är ett sätt att minska beroendet av fossila bränslen och höja självförsörjningen av energi. Fossila bränslen är den främsta källan till koldioxid utsläpp förorsakad av människan. Biomassa, å andra sidan, betraktas som en koldioxidneutral energikälla. Svavlet och kvävet i biomassan bildar dock föroreningar såsom kväveoxider (NOX) och svaveldioxid (SO2), som bidrar till försurning av mark och sjöar. Svavlet i bränslet kan även både förorsaka och förhindra korrosion i en förbränningsanläggning, beroende på förbränningen och bränslet. Huvudsyftet med detta arbete var att få en bättre förståelse om hur utsläppen av NOX och SO2 bildas från bränslebundet kväve och svavel vid förbränning av olika biobränslen. Mätkampanjer i fullskaliga förbränningsanläggningar utfördes, där gassammansättningen mättes i eldstaden och rökgasen. Förståelsen om gaskemin i eldstaden är viktig, för att möjliggöra utvecklandet av renare och effektivare förbränningsanläggningar. Ett annat syfte med arbetet var att klargöra om sulfatering av askkomponenter vid förbränning av biobränslen med olika askegenskaper. Alkaliklorider som bildas vid biomassaförbränning kan orsaka korrosion av värmeöverföringsytor. Svavlet i bränslet visade sig ha en viktig roll i att sulfatera alkaliklorider till mindre korrosiva alkalisulfater. Närvaron av gasformig svavelsyra i rökgaskanalen av förbränningsanläggningar studerades även. Kondensering av svavelsyra leder till korrosion av rökgaskanalen och dess delar. Om svavelsyrakoncentrationen i rökgasen är känd, kan daggpunktstemperaturen beräknas och kondensering av svavelsyra förhindras. I arbetet utvecklades en mätmetod för att mäta låga koncentrationer av gasformig svavelsyra i rökgaser. Denna metod användes för att undersöka risken av lågtemperaturkorrosion orsakad av svavelsyra i förbränningsanläggningar. ------------------------------------------------------------------------------------------------------------ Käyttämällä biomassaa energianlähteenä voidaan vähentää sähkön- ja lämmöntuotannon riippuvuutta fossiilisiin polttoaineisiin. Biomassan käytöllä voidaan myös lisätä energiantuotannon omavaraisuutta. Fossiiliset polttoaineet ovat pääasiallinen syy ihmisen aiheuttamiin hiilidioksidipäästöihin. Biomassa sen sijaan luetaan hiilidioksidineutraaleihin energianlähteisiin. Biopolttoaineiden käytössä tosin vapautuu typpi- ja rikkioksideja, jotka edesauttavat maaperän ja merien happamoitumista. Lisäksi biopolttoaineen rikki voi sekä vähentää että aiheuttaa laitteiden korroosiota energiantuotannossa riippuen biopolttoaineesta ja palamisesta. Tämän työn päätavoitteena oli selvittää mitä biopolttoaineeseen sitoutuneelle typelle ja rikille tapahtuu teollisissa polttolaitoksissa. Kyseisten oksidien muodostumista tutkittiin polttamalla eri biomassoja polttolaitoksissa. Tutkimukset toteutettiin mittauskampanjoilla useissa polttolaitoksissa. Kaasujen koostumusta mitattiin sekä tulipesässä, että savukaasuista. Kaasujen koostumus varsinkin tulipesässä on tärkeää, jotta tulevaisuudessa voidaan rakentaa puhtaampia ja tehokkaampia polttolaitoksia. Työn toisena tavoitteena oli selvittää biomassan polton yhteydessä tapahtuvaa tuhkan sulfatoitumista. Alkalikloridit, joita muodostuu biomassan poltossa, voivat aiheuttaa lämmönsiirtopintojen korroosiota. Rikki osoittautui tärkeäksi osaksi prosessia, jossa korroosiota aiheuttavat alkalikloridit sulfatoituivat vähemmän korrosoiviksi alkalisulfaateiksi. Myös kaasumaisen rikkihapon läsnäoloa savukaasuissa tutkittiin. On todettu, että kaasumuotoinen rikkihappo johtaa korroosioon savukaasukanavan kylmässä päässä ja sen eri osissa rikkihapon tiivistyessä lämpötilan laskiessa. Mikäli rikkihapon pitoisuus savukaasussa tiedetään, sen kastepiste voidaan laskea ja tiivistyminen estää. Tässä työssä kehitettiin mittausmenetelmä rikkihapon alhaisten pitoisuuksien mittaamiseen. Menetelmää hyödynnettiin polttolaitoksissa, joissa tutkittiin rikkihapon tiivistymisestä johtuvaa korroosiota.

Industrial-Scale hydrothermal carbonization of waste sludge materials for fuel production

Hydrothermal carbonization (HTC) is a thermochemical process used in the production of charred matter similar in composition to coal. It involves the use of wet, carbohydrate feedstock, a relatively low temperature environment (180 °C-350 °C) and high autogenous pressure (up to 2,4 MPa) in a closed system. Various applications of the solid char product exist, opening the way for a range of biomass feedstock materials to be exploited that have so far proven to be troublesome due to high water content or other factors. Sludge materials are investigated as candidates for industrial-scale HTC treatment in fuel production. In general, HTC treatment of pulp and paper industry sludge (PPS) and anaerobically digested municipal sewage sludge (ADS) using existing technology is competitive with traditional treatment options, which range in price from EUR 30-80 per ton of wet sludge. PPS and ADS can be treated by HTC for less than EUR 13 and 33, respectively. Opportunities and challenges related to HTC exist, as this relatively new technology moves from laboratory and pilot-scale production to an industrial scale. Feedstock materials, end-products, process conditions and local markets ultimately determine the feasibility of a given HTC operation. However, there is potential for sludge materials to be converted to sustainable bio-coal fuel in a Finnish context.

Public and private sector cooperative opportunities in the Finnish healthcare internationalization : views from the public sector’s perspective

Traditionally mostly publicly provided Finnish healthcare services are confronted today by the evident challenge of rising healthcare costs as the expenditure on health and social case has exceeded Finland’s national GDP growth significantly since the new millennium. While the opening of the traditional barriers through the EU’s new patient directive resulting in increasing international competition and the free flow of patients within the EU present opportunities for the Finnish healthcare services industry there are also several challenges for the existing healthcare system as proposed by the Ministry of Employment and the Economy in 2011. Due to the structure and nature of the current Finnish healthcare service system the greatest potential for internationalization is seen from a joint cooperation of the public and private sectors in an internationalization network for Finnish healthcare services. As its formation has recently also taken as a strategic initiative to be completed by the Ministry of Employment and the Economy and no earlier research exists on how this is seen in practice by the network actors, the purpose of this study is to examine the proposed solution of forming an internationalization network between the public and private sector actors in Finland in practice from the viewpoint of public sector actors. The research relied heavily on the reports by the Finnish Ministries in understanding the current situation of the Finnish healthcare services internationalization and its potential. Suitable theories were also used to build a more comprehensive view of the matter. The study applied a qualitative research approach on the explorative research problem. The data collection was achieved through expert interviews in two of the largest Finnish public healthcare service providers; the Turku and Helsinki Central University Hospitals. Expert interviews were considered as the most suitable method for data collection in order to create an in-depth understanding of the topic within the limitations of this thesis. In turn, two different public healthcare service providers were chosen to give a broader view of the field instead of focusing on a specific unit and also to allow a possible comparison between the two different organizations. The latter however was shown not to be suitable for the purposes of this study as the opinions of the respondents varied largely also within their own organizations. The conclusion is that while the actors agree on the evident internationalization of Finnish healthcare services, there are several large-scale structural challenges effectively preventing such activities while at the same time the opportunities within Finland vary, as there are several niches but no real large-scale advantages in the highly competitive industry. Interest towards cooperation between the sectors are seen especially in exploiting the advantages offered by the private sector in commercialization and marketization, yet however no clear views exist on how these activities should be governed or structured in the short-term as a larger reform of the entire Finnish healthcare service sector is needed in the long-term.
