This thesis is a preliminary study targeting South-Eastern Finland. The objective was to find out the financial and functional readiness and willingness of the small and medium-sized enterprises of the region to manufacture and sell distributed bioenergy solutions collaboratively as a business network. In this case these solutions mean small-scale (0.5 - 3 MW) woodchips-operated combined heat and power (CHP) plants. South-Eastern Finland has suffered from a decline in the recent years, mostly due to the problems of the traditionally strong industrial know-how area of the region, the paper industry. Local small and medium-sized companies will have to find new ways to survive the toughening competition. A group of 40 companies from suitable industries were selected and financial and comparative analysis was performed on them. Additionally 19 managing directors of the companies were selected for an interview to find out their views on networking, its requirements, advantages and the general interest in it. The studied companies were found to be generally in fairly good financial condition and in that sense, fit for networking activities. The interviews revealed that the companies were capable of producing all the needed elements for the plants in question, and the managers appeared to be very interested in and have a positive attitude towards such business networks. Thus it can be said that the small and medium-sized companies of the region are capable of and interested in manufacturing small bio-CHP plants as a production network.

The aim of the study is to find out “What are the challenges to overcome for the successful nanotechnology commercialization in Russia?” Working closely with the case country was definitely an advantage when it comes to the understanding of the research subject. The thesis is divided to two parts: first part examines the concept of technology commercialization and identifies unique aspects of the process in context of nanotechnology. Second part is dedicated to an empirical research, investigating current status of nanotechnology commercialization in Russia. For the purpose of this study, Russian and international scientists, researchers, entrepreneurs, industry and government representatives were interviewed systematically during 2007 – 2009. Based on the research done it can be concluded that immense public funding provides necessary support for the development of Russian nanotechnology industry. However, investments alone do not address important structural shortcomings of a national innovation system, which in turn slow down the progress. Taking into consideration gap between science and business and challenging IPR legislation, expected significant economic impact in Russia may be overestimated. Nevertheless it should be noted that development of nanotechnology is advancing rapidly and therefore, the state of commercialization is changing accordingly, even while this lines are written.

In recent years, the network vulnerability to natural hazards has been noticed. Moreover, operating on the limits of the network transmission capabilities have resulted in major outages during the past decade. One of the reasons for operating on these limits is that the network has become outdated. Therefore, new technical solutions are studied that could provide more reliable and more energy efficient power distributionand also a better profitability for the network owner. It is the development and price of power electronics that have made the DC distribution an attractive alternative again. In this doctoral thesis, one type of a low-voltage DC distribution system is investigated. Morespecifically, it is studied which current technological solutions, used at the customer-end, could provide better power quality for the customer when compared with the current system. To study the effect of a DC network on the customer-end power quality, a bipolar DC network model is derived. The model can also be used to identify the supply parameters when the V/kW ratio is approximately known. Although the model provides knowledge of the average behavior, it is shown that the instantaneous DC voltage ripple should be limited. The guidelines to choose an appropriate capacitance value for the capacitor located at the input DC terminals of the customer-end are given. Also the structure of the customer-end is considered. A comparison between the most common solutions is made based on their cost, energy efficiency, and reliability. In the comparison, special attention is paid to the passive filtering solutions since the filter is considered a crucial element when the lifetime expenses are determined. It is found out that the filter topology most commonly used today, namely the LC filter, does not provide economical advantage over the hybrid filter structure. Finally, some of the typical control system solutions are introduced and their shortcomings are presented. As a solution to the customer-end voltage regulation problem, an observer-based control scheme is proposed. It is shown how different control system structures affect the performance. The performance meeting the requirements is achieved by using only one output measurement, when operating in a rigid network. Similar performance can be achieved in a weak grid by DC voltage measurement. An additional improvement can be achieved when an adaptive gain scheduling-based control is introduced. As a conclusion, the final power quality is determined by a sum of various factors, and the thesis provides the guidelines for designing the system that improves the power quality experienced by the customer.

The age-old adage goes that nothing in this world lasts but change, and this generation has indeed seen changes that are unprecedented. Business managers do not have the luxury of going with the flow: they have to plan ahead, to think strategies that will meet the changing conditions, however stormy the weather seems to be. This demand raises the question of whether there is something a manager or planner can do to circumvent the eye of the storm in the future? Intuitively, one can either run on the risk of something happening without preparing, or one can try to prepare oneself. Preparing by planning for each eventuality and contingency would be impractical and prohibitively expensive, so one needs to develop foreknowledge, or foresight past the horizon of the present and the immediate future. The research mission in this study is to support strategic technology management by designing an effective and efficient scenario method to induce foresight to practicing managers. The design science framework guides this study in developing and evaluating the IDEAS method. The IDEAS method is an electronically mediated scenario method that is specifically designed to be an effective and accessible. The design is based on the state-of-the-art in scenario planning, and the product is a technology-based artifact to solve the foresight problem. This study demonstrates the utility, quality and efficacy of the artifact through a multi-method empirical evaluation study, first by experimental testing and secondly through two case studies. The construction of the artifact is rigorously documented as justification knowledge as well as the principles of form and function on the general level, and later through the description and evaluation of instantiations. This design contributes both to practice and foundation of the design. The IDEAS method contributes to the state-of-the-art in scenario planning by offering a light-weight and intuitive scenario method for resource constrained applications. Additionally, the study contributes to the foundations and methods of design by forging a clear design science framework which is followed rigorously. To summarize, the IDEAS method is offered for strategic technology management, with a confident belief that it will enable gaining foresight and aid the users to choose trajectories past the gales of creative destruction and off to a brighter future.

Implementering av ett informationssystem ur en organisatorisk synvinkel initieras av en idé om ett system och avslutas då användningen av det inte längre kräver en medveten ansträngning. Ifall tolkningen av implementering är denna, är det fråga om en långsam och komplicerad process, som berör organisationens alla parter. Ny informationsteknologi anses påverka flertalet arbetsprocesser och organiseringen av det dagliga arbetet. Möjligheterna att ta i bruk systemet och utnyttja det är många. I avhandlingen undersöks implementering av ett system för att administrera hemvårdsbesök där hemvårdare använde handdatorer för att registrera information om besökens längd och innehåll. I avhandlingen observeras vilka förändringar som sker i arbetets praxis p.g.a. det nya systemet och hur dessa förändringar påverkar vårdarbetet. Forskningen inleds med att strukturera teorier om arbetspraxis för kommande analys. Arbetspraxis är inarbetade och rutinmässiga arbetssätt i arbetets sociomateriella omgivning. Arbetspraxis i avhandlingen innebär hemvårdarens praxis och upplevd erfarenhet, där verksamheten informeras av gemensamma arbetssätt, projekt, identiteter och intressen. Organisationens auktoritet kommer även fram i den förverkligade arbetspraxisen. Forskningen genomfördes som en etnografisk longitudinell studie under åren 2001-2004. I studien observerades hur nyttjandet av handdatorerna framskred ur ett organisatoriskt perspektiv. Hemvårdares arbete och verksamhet (arbetspraxis) observerades både under vårdsbesök och under pauser. Därtill intervjuades hemvårdarna för att erhålla en bättre förståelse för de rationaliteter som styr arbetet och hur systemet togs i bruk. Dokument relaterade till projektet att införa ett nytt system och administrativa dokument har utnyttjats som källmaterial. Analysen av källmaterialet styrdes av det teoretiska tillvägagångssättet att undersöka arbetspraxis. Problem som identifierades i samband med införandet av systemet och de förändringar som det medförde analyserades i detalj. Parallellt analyserades organisatorisk makt, kontroll och arbetsidentitet. Undersökningen beskriver hur det nya systemet gradvis anpassades till hemvården efter ett initialt motstånd. Under själva implementering av systemet ifrågasattes tidigare arbetspraxis och inställningen till den eftersom arbetspraxisens materiella omgivning förändrades. Det teoretiska tillvägagångssättet i att undersöka arbetspraxis framhäver vårdarens agerande i förändringsprocessen. Resultatet av forskningen visar vikten av realistiska målsättningar, givande av gruppstöd med återkoppling samt förmåga att anpassa sig till det oväntade vid införande av informationssystem.

This dissertation describes a networking approach to infinite-dimensional systems theory, where there is a minimal distinction between inputs and outputs. We introduce and study two closely related classes of systems, namely the state/signal systems and the port-Hamiltonian systems, and describe how they relate to each other. Some basic theory for these two classes of systems and the interconnections of such systems is provided. The main emphasis lies on passive and conservative systems, and the theoretical concepts are illustrated using the example of a lossless transfer line. Much remains to be done in this field and we point to some directions for future studies as well.

The objective of this master’s thesis was to examine technology-based smart home devices and services. Topic was approached through basic theories, transaction cost theory and resource-based view in order to build basis for this thesis. Conceptual framework was discussed by means of networks, value networks and service systems which provide a useful framework for service development. The needs of the elderly living at home were discussed in order to find out which technology-based services could be used to satisfy the needs. Segmentation and need data collected previously during proactive home visits was exploited and additionally a survey targeted to experts and professionals of social and health care sector was done to verify the needs. Finally, the results of the survey were analyzed using quality function deployment method to figure out the most important and suitable service offerings for the elderly. As a conclusion of analysis, social media and monitoring services are the most useful technology-based services. However, traditional home services will still maintain their necessity too.

"Biopolttoaineiden saatavuus ja hankintalogistiikka Kaakkois-Suomessa" -hankkeen tavoitteena oli tuottaa ajantasaista ja paikkaan sidottua tietoa energiatuotantoon soveltuvan biomassan saatavuudesta ja biomassapotentiaalin tehokkaan käytön mahdollistavasta logistiikkajärjestelmästä Kaakkois-Suomen alueella. Tarkastelussa mukana olleet polttoaineet eli metsä- ja peltobiomassat sekä turve ovat ns. paikallisia polttoaineita, joiden hankinta tapahtuu maaseudulta, ensisijaisesti mahdollisimman läheltä kutakin käyttöpaikkaa. Hankkeessa tutkittiin mahdollisuuksia lisätä paikallista polttoaineenhankintaa, kuljetusmääriä ja -kalustoa järkevästi 2010-luvulla toteutettavan energiapolitiikan myötä kasvavan polttoainetarpeen puitteissa. Rautatie- ja vesitiekuljetusten hyödyntämistä logistiikassa tutkittiin kahden tapaustutkimuksen avulla. Tutkittavia asioita olivat myös tuotantoketjujen lisääntyvä työvoimatarve sekä maantieteellisesti laajenevan raaka-ainehankinnan kasvihuonekaasupäästöistä aiheutuvat ympäristövaikutukset. Tärkeimpinä tuloksina saatiin tietoa siitä, kuinka laajalle alueelle biopolttoaineiden hankinta eri asiantilojen vallitessa Kaakkois-Suomen alueella ulottuu, ja millaisia hankintalogistiikkaan liittyviä ratkaisuja voidaan ottaa käyttöön alueellisen polttoainepulan muodostuessa. Logistiikan kannalta Kaakkois-Suomen etuja ovat monipuoliset kuljetusverkostot, mutta toisaalta varsinkin hyvät yhteydet ulkomaille rajoittavat paikallisesti investointiaktiivisuutta bioenergian tuotanto- ja käsittelykaluston osalta. Lisäksi maaseudun yrittäjien keskuudessa epävarmuutta aiheuttavat heilahtelevat raakapuumarkkinat ja muuttuva energiatukipolitiikka.

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.

The most important knowledge in firms is mostly tacit and embedded in individuals within the organization. This background knowledge that firms possess is used for creation of new knowledge and innovations. As firms today greatly concentrate on their core competencies, they need external knowledge from various collaboration partners. Thus, collaborative relationship governance, as well as control (use of appropriability mechanisms) over background (the input from each firm in innovative activities) and foreground knowledge (the output of collaboration activities) is needed in order to successfully create and capture value from innovative activities without losing core knowledge and competitiveness. Even though research has concentrated on knowledge protection and knowledge sharing, studies that combine both of these views and examine the effects of sharing and protection on value creation and capture have been rather limited. Studies have mainly focused on the protection of the output of innovation while forgetting the protection of the input of innovation. On the other hand, as the research concentrating on the output of innovation tends to favor formal mechanisms, informal mechanisms have remained more unknown to researchers as well as managers. This research aims to combine the perspectives of knowledge sharing and knowledge protection and their relationship with value creation and value capture. The sharing and protection are viewed from two points of view: the use of appropriability mechanisms, as well as governance of the collaborative relationship. The study consists of two parts. The first part introduces the research topic and discusses the overall results. The second part comprises six complementary research publications. Both qualitative and quantitative research methods are used in the study. In terms of results, the findings enhance understanding of the combined use of formal and informal mechanisms for knowledge protection and sharing. Informal mechanisms appear to be emphasized in the protection of background knowledge, and thus are prerequisites for innovation, whereas formal mechanisms are relied on more for protecting the results of innovative activities. However, the simultaneous use of the formal and informal mechanisms that are relevant to the particular industry and innovation context is recommendedthroughout the collaborative innovation process. Further, the study adds to the current knowledge on HRM as an appropriability mechanism: on the firm level its uses include assessing and hedging against employee-related risks such as knowledge leaking and knowledge leaving. A further contribution is to the research on HRM protection and its interrelations with other appropriability mechanisms, its constituents, and its potential use in the area of knowledge protection.

The electronic learning has become crucial in higher education with increased usage of learning management systems as a key source of integration on distance learning. The objective of this study is to understand how university teachers are influenced to use and adopt web-based learning management systems. Blackboard, as one of the systems used internationally by various universities is applied as a case. Semi-structured interviews were made with professors and lecturers who are using Blackboard at Lappeenranta University of Technology. The data collected were categorized under constructs adapted from Unified Theory of Acceptance and Use of Technology (UTAUT) and interpretation and discussion were based on reviewed literature. The findings suggest that adoption of learning management systems by LUT teachers is highly influenced by perceived usefulness, facilitating conditions and gained experience. The findings also suggest that easiness of using the system and social influence appear as medium influence of adoption for teachers at LUT.

Tämä diplomityö käsittelee Andritz Oy:n BFB-voimalaitosten tarjoustoimintaan kehitettävää esisuunnitteluohjelmistoa. Tässä työssä on esitelty kattiloiden tarjoustoimintaan liittyviä seikkoja etenkin laskennan ja tekniikan näkökulmasta. Työssä on myös koottu tietoa polttoaineista ja BFB-kattiloiden suunnittelusta ja mitoituksesta. Työn aikana kehitettiin ohjelmisto, jolla on mahdollista luoda eri BFB-kattila tarjousprojekteja. Projekteille on mahdollista luoda useita eri taselaskelmia eri lähtöarvoilla ja useilla eri polttoaineilla, sekä niiden seoksilla. Ohjelmakehityksessä painotettiin suunnittelun joustavuutta eri konfiguraatioille, mahdollisimman tarkkaa laskentaa ja ylläpidon merkitystä. Ohjelmistokehityksessä päätettiin käyttää Microsoft Excel ohjelmistoa laskentaympäristönä. Tällöin pystyttiin luomaan käyttäjille tuttu käyttöympäristö ja mahdollistaa vanhojen hyväksi todettujen laskentapohjien käyttö apuna kehityksessä. Tämä mahdollistaa myös ylläpidon toimialueen ammattilaisten toimesta jatkossa.
