On Value Creation at an Industrial Intersection – Bioenergy in the Forest and Energy Sectors

The traditional forest industry is a good example of the changing nature of the competitive environment in many industries. Faced with drastic challenges forestindustry companies are forced to search for new value-creating strategies in order to create competitive advantage. The emerging bioenergy business is now offering promising avenues for value creation for both the forest and energy sectors because of their complementary resources and knowledge with respect to bioenergy production from forest-based biomass. The key objective of this dissertation is to examine the sources of sustainable competitive advantage and the value-creation opportunities that are emerging at the intersection between the forest and energy industries. The research topic is considered from different perspectives in order to provide a comprehensive view of the phenomenon. The study discusses the business opportunities that are related to producing bioenergy from forest-based biomass, and sheds light on the greatest challenges and threats influencing the success of collaboration between the forest and energy sectors. In addition, it identifies existing and potential bioenergy actors, and considers the resources and capabilities needed in order to prosper in the bioenergy field. The value-creation perspective is founded on strategic management accounting, the theoretical frameworks are adopted from the field of strategic management, and the future aspect is taken into account through the application of futures studies research methodology. This thesis consists of two parts. The first part provides a synthesis of the overall dissertation, and the second part comprises four complementary research papers. There search setting is explorative in nature, and both qualitative and quantitative research methods are used. As a result, the thesis lays the foundation for non-technological studies on bioenergy. It gives an example of how to study new value-creation opportunities at an industrial intersection, and discusses the main determinants affecting the value-creation process. In order to accomplish these objectives the phenomenon of value creation at the intersection between the forest and energy industries is theorized and connected with the dynamic resource-based view of the firm.

Constantes de acidez de ácidos dipróticos a partir de titulações potenciométricas: ilustração dos princípios do cálculo através da construção de um algoritmo muito simples

This work describes the creation of an very simple calculation algorithm, based in basic chemical and mathematic principles, for the calculation of weak diprotic acid dissociation constants as, for example, amino acids, from potentiometric titrations. For an easier understanding of the algorithm the logical reasoning of this calculus is schematized in a diagram of blocks. In the second part of the work the algorithm is applied to an Excel calculation sheet to determine the dissociation constants of Nicotinic Acid and Glycine, from the respective potentiometric titration curves. The values obtained using this algorithm are compared with those estimated by Hyperquad2008 (program generally used for this type of calculus) and also with the values of a stability constants database.

Service Description Creation Empowerment to Mobile End Users

Increasing usage of Web Services has been result of efforts to automate Web Services discovery and interoperability. The Semantic Web Service descriptions create basis for automatic Web Service information management tasks such as discovery and interoperability. The discussion of opportunities enabled by service descriptions have arisen in recent years. The end user has been considered only as a consumer of services and information sharing occurred from one service provider to public in service distribution. The social networking has changed the nature of services. The end user cannot be seen anymore only as service consumer, because by enabling semantically rich environment and right tools, the end user will be in the future the producer of services. This study investigates the ways to provide for end users the empowerment to create service descriptions on mobile device. Special focus is given to the changed role of the end user in service creation. In addition, the Web Services technologies are presented as well as different Semantic Web Service description approaches are compared. The main focus in the study is to investigate tools and techniques to enable service description creation and semantic information management on mobile device.

Stress testing and risk evaluation of new capacity payment algorithm proposed by Market Council

In the Russian Wholesale Market, electricity and capacity are traded separately. Capacity is a special good, the sale of which obliges suppliers to keep their generating equipment ready to produce the quantity of electricity indicated by the System Operator. The purpose of the formation of capacity trading was the maintenance of reliable and uninterrupted delivery of electricity in the wholesale market. The price of capacity reflects constant investments in construction, modernization and maintenance of power plants. So, the capacity sale creates favorable conditions to attract investments in the energy sector because it guarantees the investor that his investments will be returned.

Considering Target Groups in the Creation of a Comprehensive City Branding Process

The aim of the research was to create a comprehensive city branding process. This was done by identifying the key target groups of the city and considering them in the city branding process. Also key stakeholders were identified and taken into consideration when creating the branding process. As an empirical study, three first stages of the city branding process were implemented for the city of Lappeenranta having "students" as the case target group. An interview with the city officials was conducted, as well as a student survey on the current city image of Lappeenranta. Quantitative research methods were used to analyze the results of the survey. A comprehensive city branding process with eight stages was created in the research. Target groups were considered in the process by identifying the target group dependent stages. The empirical study revealed that the current city image held by the students consists of six dimensions. These dimensions were analyzed from the viewpoint of Lappeenranta with the help of an importance performance analysis.

Value co-creation in industrial buyer-seller partnerships - creating and exploiting interdependencies : an empirical case study

In summary the main findings of the study are that there seems to be is no universal definition of value in the context of industrial relationships, but a notion that it is context-, time-, and actor dependent. Value co-creation is a suitable concept in the context of buyerseller relationships. The evolution of a relationship from a transactional to a partnership is long and eventful - a process where the outcome is impossible to estimate in advance. The process is filled with differenttypes of events and also conflicts, which as a matter of fact can be seen as constructive forces in relationship development. The perceived value of a relationship is an antecedent to pursuing a high-involvement strategy; once a partnership exists, the value co-creation potential is realizable through exploiting interdependencies. Those interdependencies are the trigger for value co-creation potential. The value cocreation potential is realized though different processes of value co-creation either to achieve efficiency in exchange or effective use of resources. The logic of buyer-seller partnerships is to create and exploit interdependencies in order to create both efficiency and effective use of resources. (Summary of main findings p. 176)

Solving Leontief Input-Output Model with Trapezoidal Fuzzy Numbers and Gauss-Seidel Algorithm

In this work a fuzzy linear system is used to solve Leontief input-output model with fuzzy entries. For solving this model, we assume that the consumption matrix from di erent sectors of the economy and demand are known. These assumptions heavily depend on the information obtained from the industries. Hence uncertainties are involved in this information. The aim of this work is to model these uncertainties and to address them by fuzzy entries such as fuzzy numbers and LR-type fuzzy numbers (triangular and trapezoidal). Fuzzy linear system has been developed using fuzzy data and it is solved using Gauss-Seidel algorithm. Numerical examples show the e ciency of this algorithm. The famous example from Prof. Leontief, where he solved the production levels for U.S. economy in 1958, is also further analyzed.

GAMS MINLP Solver comparisons and some improvements to the AlphaECP algorithm

I doktorsavhandlingen undersöks förmågan att lösa hos ett antal lösare för optimeringsproblem och ett antal svårigheter med att göra en rättvis lösarjämförelse avslöjas. Dessutom framläggs några förbättringar som utförts på en av lösarna som heter GAMS/AlphaECP. Optimering innebär, i det här sammanhanget, att finna den bästa möjliga lösningen på ett problem. Den undersökta klassen av problem kan karaktäriseras som svårlöst och förekommer inom ett flertal industriområden. Målet har varit att undersöka om det finns en lösare som är universellt snabbare och hittar lösningar med högre kvalitet än någon av de andra lösarna. Det kommersiella optimeringssystemet GAMS (General Algebraic Modeling System) och omfattande problembibliotek har använts för att jämföra lösare. Förbättringarna som presenterats har utförts på GAMS/AlphaECP lösaren som baserar sig på skärplansmetoden Extended Cutting Plane (ECP). ECP-metoden har utvecklats främst av professor Tapio Westerlund på Anläggnings- och systemteknik vid Åbo Akademi.

Software for calculation of reservoir active capacity with the sequent-peak algorithm

It is presented a software developed with Delphi programming language to compute the reservoir's annual regulated active storage, based on the sequent-peak algorithm. Mathematical models used for that purpose generally require extended hydrological series. Usually, the analysis of those series is performed with spreadsheets or graphical representations. Based on that, it was developed a software for calculation of reservoir active capacity. An example calculation is shown by 30-years (from 1977 to 2009) monthly mean flow historical data, from Corrente River, located at São Francisco River Basin, Brazil. As an additional tool, an interface was developed to manage water resources, helping to manipulate data and to point out information that it would be of interest to the user. Moreover, with that interface irrigation districts where water consumption is higher can be analyzed as a function of specific seasonal water demands situations. From a practical application, it is possible to conclude that the program provides the calculation originally proposed. It was designed to keep information organized and retrievable at any time, and to show simulation on seasonal water demands throughout the year, contributing with the elements of study concerning reservoir projects. This program, with its functionality, is an important tool for decision making in the water resources management.

Data mining techniques for identification of spectrally homogeneous areas using NDVI temporal profiles of soybean crop

The aim of this study was to group temporal profiles of 10-day composites NDVI product by similarity, which was obtained by the SPOT Vegetation sensor, for municipalities with high soybean production in the state of Paraná, Brazil, in the 2005/2006 cropping season. Data mining is a valuable tool that allows extracting knowledge from a database, identifying valid, new, potentially useful and understandable patterns. Therefore, it was used the methods for clusters generation by means of the algorithms K-Means, MAXVER and DBSCAN, implemented in the WEKA software package. Clusters were created based on the average temporal profiles of NDVI of the 277 municipalities with high soybean production in the state and the best results were found with the K-Means algorithm, grouping the municipalities into six clusters, considering the period from the beginning of October until the end of March, which is equivalent to the crop vegetative cycle. Half of the generated clusters presented spectro-temporal pattern, a characteristic of soybeans and were mostly under the soybean belt in the state of Paraná, which shows good results that were obtained with the proposed methodology as for identification of homogeneous areas. These results will be useful for the creation of regional soybean "masks" to estimate the planted area for this crop.

CREATION OF INTERNATIONALIZATION CAPABILITIES IN FINNISH ENVIRONMENTAL TECHNOLOGY SME’S

The purpose of this study is to identify successful capabilities that Finnish SME’s, in the environmental technology industry, use in their internationalization efforts. It is the goal of this study to create a list of guidelines and capabilities that other SME’s in this industry can use to help be more effective in their internationalization efforts. Through a study of three Finnish SME’s, in the growing environmental technologies sector, several common internationalization capabilities were identified to be helpful in their internationalization process. The common capabilities that were identified were then categorized together to show not only what capabilities were identified but if they came from firm, location or network specific advantages. As a result of the study, three dynamic capabilities were formulated as guidelines. These guidelines are designed so that a SME based in Finland, and in the environmental technology industry, could use them to help them in their own internationalization process.

Value creation through business model in international entrepreneurship

Business model in the context of international entrepreneurship is a rather new topic in academic literature. The objective of this thesis is to examine value creation through business models in internationally entrepreneurial firms. The study examines value creation through the two partner interfaces and the customer interface of a company. Central for the study is the consideration of also the partners’ incentives. Business model construct is studied by defining the concept, examining its elements and the relationship with strategy – concluding with value creation through the concept. The international entrepreneurship chapter focuses on internationally entrepreneurial firms, inspecting the drivers behind international entrepreneurship and studying value network concept. Value creation functions as a driving theme in the theory discussion. The empirical research of the study focuses on eight Finnish internationally entrepreneurial software companies. The study is conducted as a qualitative cross-case analysis building on the single case company business model analyses. The findings suggest that the business models of software companies incorporate vast similarities. However, the degree of international experience has influence on the companies’ value creation and the way they organize their activities both in upstream and downstream of the value chain.
