A multibody dynamic model of the cross-country ski-skating technique

The objective of this thesis is the development of a multibody dynamic model matching the observed movements of the lower limb of a skier performing the skating technique in cross-country style. During the construction of this model, the formulation of the equation of motion was made using the Euler - Lagrange approach with multipliers applied to a multibody system in three dimensions. The description of the lower limb of the skate skier and the ski was completed by employing three bodies, one representing the ski, and two representing the natural movements of the leg of the skier. The resultant system has 13 joint constraints due to the interconnection of the bodies, and four prescribed kinematic constraints to account for the movements of the leg, leaving the amount of degrees of freedom equal to one. The push-off force exerted by the skate skier was taken directly from measurements made on-site in the ski tunnel at the Vuokatti facilities (Finland) and was input into the model as a continuous function. Then, the resultant velocities and movement of the ski, center of mass of the skier, and variation of the skating angle were studied to understand the response of the model to the variation of important parameters of the skate technique. This allowed a comparison of the model results with the real movement of the skier. Further developments can be made to this model to better approximate the results to the real movement of the leg. One can achieve this by changing the constraints to include the behavior of the real leg joints and muscle actuation. As mentioned in the introduction of this thesis, a multibody dynamic model can be used to provide relevant information to ski designers and to obtain optimized results of the given variables, which athletes can use to improve their performance.

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.

The Role of Universities in the Triple Helix model of innovation management within the biotechnology industry, Case example: Turku Science Park Network

Biotechnology has been recognized as the key strategic technology for industrial growth. The industry is heavily dependent on basic research. Finland continues to rank in the top 10 of Europe's most innovative countries in terms of tax-policy, education system, infrastructure and the number of patents issued. Regardless of the excellent statistical results, the output of this innovativeness is below acceptable. Research on the issues hindering the output creation has already been done and the identifiable weaknesses in the Finland's National Innovation system are the non-existent growth of entrepreneurship and the missing internationalization. Finland is proven to have all the enablers of the innovation policy tools, but is lacking the incentives and rewards to push the enablers, such as knowledge and human capital, forward. Science Parks are the biggest operator in research institutes in the Finnish Science and Technology system. They exist with the purpose of speeding up the commercialization process of biotechnology innovations which usually include technological uncertainty, technical inexperience, business inexperience and high technology cost. Innovation management only internally is a rather historic approach, current trend drives towards open innovation model with strong triple helix linkages. The evident problems in the innovation management within the biotechnology industry are examined through a case study approach including analysis of the semi-structured interviews which included biotechnology and business expertise from Turku School of Economics. The results from the interviews supported the theoretical implications as well as conclusions derived from the pilot survey, which focused on the companies inside Turku Science Park network. One major issue that the Finland's National innovation system is struggling with is the fact that it is technology driven, not business pulled. Another problem is the university evaluation scale which focuses more on number of graduates and short-term factors, when it should put more emphasis on the cooperation success in the long-term, such as the triple helix connections with interaction and knowledge distribution. The results of this thesis indicated that there is indeed requirement for some structural changes in the Finland's National innovation system and innovation policy in order to generate successful biotechnology companies and innovation output. There is lack of joint output and scales of success, lack of people with experience, lack of language skills, lack of business knowledge and lack of growth companies.

Irisweb on jo lähtökohtaisesti suun-niteltu toimintaympäristöltään vastaamaan niihin tarpeisiin, joita VHK:lla on, joten toimin-not vastaavat tarpeita hyvin. MATI sisältää käytössä testatun, kestävän ja nopeasti käyt-töönotettavan kokonaisuuden. Eri järjestelmien tekniset ratkaisut pohjautuvat paljon samoi-hin tekniikoihin, osalla on sama tiedonsiirtoalusta. Järjestelmien soveltuvuus eri osa-alueisiin vaihteli. Tutkimuksen tuloksena soveltuvin järjestelmä on MATI. Tulevaisuudessa eriytyvien järjestelmien sulauttaminen ja niiden parhaiden ominaisuuksien yhdistäminen näyttäisi olevan ainoa suunta. COTS-tekniikan käyttäminen ja SOA suunnit-telun pohjana ohjaavat kehitystä kohti verkostokeskeisyyttä.

Development of porous glass-fiber reinforced composite for bone implants. Evaluation of antimicrobial effect and implant fixation

Cranial bone reconstructions are necessary for correcting large skull bone defects due to trauma, tumors, infections and craniotomies. Traditional synthetic implant materials include solid or mesh titanium, various plastics and ceramics. Recently, biostable glass-fiber reinforced composites (FRC), which are based on bifunctional methacrylate resin, were introduced as novel implant solution. FRCs were originally developed and clinically used in dental applications. As a result of further in vitro and in vivo testing, these composites were also approved for clinical use in cranial surgery. To date, reconstructions of large bone defects were performed in 35 patients. This thesis is dedicated to the development of a novel FRC-based implant for cranial reconstructions. The proposed multi-component implant consists of three main parts: (i) porous FRC structure; (ii) bioactive glass granules embedded between FRC layers and (iii) a silver-polysaccharide nanocomposite coating. The porosity of the FRC structure should allow bone ingrowth. Bioactive glass as an osteopromotive material is expected to stimulate the formation of new bone. The polysaccharide coating is expected to prevent bacterial colonization of the implant. The FRC implants developed in this study are based on the porous network of randomly-oriented E-glass fibers bound together by non-resorbable photopolymerizable methacrylate resin. These structures had a total porosity of 10–70 volume %, of which > 70% were open pores. The pore sizes > 100 μm were in the biologically-relevant range (50-400 μm), which is essential for vascularization and bone ingrowth. Bone ingrowth into these structures was simulated by imbedding of porous FRC specimens in gypsum. Results of push-out tests indicated the increase in the shear strength and fracture toughness of the interface with the increase in the total porosity of FRC specimens. The osteopromotive effect of bioactive glass is based on its dissolution in the physiological environment. Here, calcium and phosphate ions, released from the glass, precipitated on the glass surface and its proximity (the FRC) and formed bone-like apatite. The biomineralization of the FRC structure, due to the bioactive glass reactions, was studied in Simulated Body Fluid (SBF) in static and dynamic conditions. An antimicrobial, non-cytotoxic polysaccharide coating, containing silver nanoparticles, was obtained through strong electrostatic interactions with the surface of FRC. In in vitro conditions the lactose-modified chitosan (chitlac) coating showed no signs of degradation within seven days of exposure to lysozyme or one day to hydrogen peroxide (H2O2). The antimicrobial efficacy of the coating was tested against Staphylococcus aureus and Pseudomonas aeruginosa. The contact-active coating had an excellent short time antimicrobial effect. The coating neither affected the initial adhesion of microorganisms to the implant surface nor the biofilm formation after 24 h and 72 h of incubation. Silver ions released to the aqueous environment led to a reduction of bacterial growth in the culture medium.

Open Environmental Information Upon Disclosure Request in China: The Paradox of Legal Mobilization

Taking a realist view that law is one form of politics, this dissertation studies the roles of citizens and organizations in mobilizing the law to request government agencies to disclose environmental information in China, and during this process, how the socio-legal field interacts with the political-legal sphere, and what changes have been brought about during their interactions. This work takes a socio-legal approach and applies methodologies of social science and legal analysis. It aims to understand the paradox of why and how citizens and entities have been invoking the law to access environmental information despite the fact that various obstacles exist and the effectiveness of the new mechanism of environmental information disclosure still remains low. The study is largely based on the 28 cases and eight surveys of environmental information disclosure requests collected by the author. The cases and surveys analysed in this dissertation all occurred between May 2008, when the OGI Regulations and the OEI Measures came into effect, and August 2012 when the case collection was completed. The findings of this study have shown that by invoking the rules of law made by the authorities to demand government agencies disclosing environmental information, the public, including citizens, organizations, law firms, and the media, have strategically created a repercussive pressure upon the authorities to act according to the law. While it is a top-down process that has established the mechanism of open government information in China, it is indeed the bottom-up activism of the public that makes it work. Citizens and organizations’ use of legal tactics to push government agencies to disclose environmental information have formed not only an end of accessing the information but more a means of making government agencies accountable to their legal obligations. Law has thus played a pivotal role in enabling citizen participation in the political process. Against the current situation in China that political campaigns, or politicization, from general election to collective actions, especially contentious actions, are still restrained or even repressed by the government, legal mobilization, or judicialization, that citizens and organizations use legal tactics to demand their rights and push government agencies to enforce the law, become de facto an alternative of political participation. During this process, legal actions have helped to strengthen the civil society, make government agencies act according to law, push back the political boundaries, and induce changes in the relationship between the state and the public. In the field of environmental information disclosure, citizens and organizations have formed a bottom-up social activism, though limited in scope, using the language of law, creating progressive social, legal and political changes. This study emphasizes that it is partial and incomplete to understand China’s transition only from the top-down policy-making and government administration; it is also important to observe it from the bottom-up perspective that in a realistic view law can be part of politics and legal mobilization, even when utterly apolitical, can help to achieve political aims as well. This study of legal mobilization in the field of environmental information disclosure also helps us to better understand the function of law: law is not only a tool for the authorities to regulate and control, but inevitably also a weapon for the public to demand government agencies to work towards their obligations stipulated by the laws issued by themselves.

Varastointikapasiteetin käytön tehostaminen

Tutkimuksessa selvitettiin kuormalavoille varastoidun materiaalin varastointikapasiteetin tehostamista mahdollisimman kustannustehokkaasti. Varastointikapasiteetin tehostamiseksi pyrittiin löytämään ratkaisut kahdelle esimerkkivarastolle uusia varastointiteknologioita ja materiaalinkäsittelylaitteita hyödyntämällä. Tutkimuksen aihe perustui Maavoimien esikunnan huolto-osaston tarpeeseen saada tutkittua mahdollisuuksia nykyisten varastojen varastointikapasiteetin tehostamiseksi. Nykyisten varastosuojien varastointikapasiteetin käytön tehostamisella voidaan välttää uusien kalliiden varastosuojien rakentaminen. Tutkimus laadittiin suorittamalla kirjallisuustutkimus varastoinnin perusteisiin, varastojen jaotteluun, tilasuunnitteluun, varastointiteknologioihin sekä materiaalinkäsittelylaitteisiin. Varastoinnin nykytilan kartoittamiseksi perehdyttiin puolustusvoimien varastointisuunnitelman version 3.0 luonnokseen. Esimerkkivarastojen nykytilanteen selvittäminen toteutettiin laatimalla varastoille kysely sekä vierailemalla toisella varastolla. Esimerkkivarastoille suunniteltiin Intolog Vantaa Oy:n edustajien kanssa uudet hyllyjärjestelmävaihtoehdot. Tutkija laati itse toiset vaihtoehdot molemmille varastoille Intolog Vantaa Oy:n vaihtoehtojen vertaamiseksi. Vaihtoehdoille laskettiin tunnusluvut ja investointikustannukset, joita vertailtiin sekä keskenään että nykytilaan. Tutkimustyön tuloksena syntyi laskelma saavutettavasta varastointikapasiteetin lisäyksestä investointikustannuksineen. Esimerkkivaraston 1 osalta kapasiteettia on mahdollista lisätä liikkuvia sekä push back -hyllystöjä käyttämällä noin 1 500 kuormalavapaikkaa (40 %) investointikustannusten ollessa noin 680 000 euroa. Esimerkkivaraston 2 osalta lisäys push back -hyllystöillä on noin 500 kuormalavapaikkaa (35 %) investointikustannusten ollessa noin 350 000 euroa. Tutkimuksen tuloksien perusteella voidaan uusia varastointiteknologioita hyödyntämällä lisätä puolustusvoimien varastoihin varovaisesti arvioiden noin 26 000 kuormalavapaikkaa. Jokainen varasto on kuitenkin erilainen, joten tutkimuksen tuloksia pitää tarkastella varastokohtaisesti.

Understanding Online Game Players' Post-adoption Behavior: an Investigation of Social Network Games in China

Retaining players and re-attracting switching players has long been a central topic for SNG providers with regard to the post-adoption stage of playing an online game. However, there has not been much research which has explored players’ post-adoption behavior by incorporating the continuance intention and the switching intention. In addition, traditional IS continuance theories were mainly developed to investigate users’ continued use of utilitarian IS, and thus they may fall short when trying to explain the continued use of hedonic IS. Furthermore, compared to the richer literature on IS continuance, far too little attention has been paid to IS switching, leading to a dearth of knowledge on the subject, despite the increased incidence of the switching phenomenon in the IS field. By addressing the limitations of prior literature, this study seeks to examine the determinants of SNG players’ two different post-adoption behaviors, including the continuance intention and the switching intention. This study takes a positivist approach and uses survey research method to test five proposed research models based on Unified Theory of Acceptance and Use of Technology 2; Use and Gratification Theory; Push-Pull-Mooring model; Cognitive Dissonance Theory; and a self-developed model respectively with empirical data collected from the SNG players of one of the biggest SNG providers in China. A total of 3919 valid responses and 541 valid responses were used to examine the continuance intention and the switching intention, respectively. SEM is utilized as the data analysis method. The proposed research models are supported by the empirical data. The continuance intention is determined by enjoyment, fantasy, escapism, social interaction, social presence, social influence, achievement and habit. The switching intention is determined by enjoyment, satisfaction, subjective norms, descriptive norms, alternative attractiveness, the need for variety, change experience, and adaptation cost. This study contributes to IS theories in three important ways. Firstly, it shows IS switching should be included in IS post-adoption research together with IS continuance. Secondly, a modern IS is usually multi-functional and SNG players have multiple reasons for using a SNG, thus a player’s beliefs about the hedonic, social and utilitarian perceptions of their continued use of the SNG exert significant effects on the continuance intention. Thirdly, the determinants of the switch ing intention mainly exert push, pull, and mooring effects. Players’ beliefs about their current SNG and the available alternatives, as well as their individual characteristics are all significant determinants of the switching intention. SNG players combine these effects in order to formulate the switching intention. Finally, this study presents limitations and suggestions for future research.

“Till gruvhålet som suger och skrämmer” : en studie i Nils Bolanders predikan under åren 1940–1950

The aim of this thesis is to examine the preaching of Nils Bolander during the years 1940–1950. Nils Bolander (1902–1959) was a Swedish minister, later bishop, in the Church of Sweden. Bolander experienced his breakthrough as a preacher and a poet during the years 1940–1950, when he was a pastor of the Engelbrekt congregation in Stockholm. One characteristic of Bolander’s poetry as well as of his sermons is a rich and poetical language. At the same time he also had a clear agenda with his sermons with regard to their contents. The primary research question of this thesis is: What was Bolander’s purpose with his sermons? In this context, two secondary research questions were asked: 1) In what way does the poetical language support and assist the purpose of the sermons? 2) How is Bolander, as an individual and a preacher, engaged in the language and the contents of the sermons? The research material of this study consists of 152 hand-­written sermon manuscripts from church services held by Nils Bolander in Stockholm during the period in question. The method of the study is qualitative research with an abductive approach. Content analysis has formed the primary tool. With regard to the main research question, the purpose of Bolander’s sermons, my study indicated that the purpose was to rouse the listeners from their routine-­like faith and push them towards commitment and active service for God. In Bolander’s theology I found strong influences from Pietism but also some traits usually associated with the theological profile of the Oxford Group. Despite these influences, Nils Bolander’s theology is mainly founded on the Lutheran interpretation of faith. With regard to the secondary research questions concerning the poetical language as well as the role of the preacher my study concludes that the language, the individual and the contents were all connected in Bolander’s preaching and formed a whole that spoke to the audience in various ways.

Co-creating value with customers as a new approach of entering new market

Global trends associated with development of information technology, globalization, industrial and economic changes are influencing on company and customer domains and thus transforming company-customer relationship. The company centric paradigm with a strong product focus shifts to a customer oriented one with a strong emphasis on customer collaboration. As a result, the customer role changes from a passive observer to an active player. Moreover, global trends contribute to transformation of competitive environment making it tougher and simplifying an access to resources previously considered as unique. All that factors push the companies towards cooperation with customers in order to identify unarticulated needs and finding the best possible solution to existing customer problems. The Master’s Thesis is done for Outotec (Lappeenranta) which considers extension of dewatering business in Russian coal market. Research aims to identify key features of coal preparation and dewatering of fine coal and tailings in Russian preparation plants; analyze the state of Russian coal market and evaluate market potential for Outotec dewatering solutions. The study has a qualitative nature and implements an action research methodology that involves both creation of knowledge and introduction of changes into the system. The base for taking actions is formed by theoretical framework that targets on describing company - customer interaction and has selected co-creation as the most appropriate method of customer involvement. The integration of co-creation approach into an action research cycle allows not only fulfilling the research objectives but also facilitates organizational learning and intraorganizational collaboration, assists in establishing customer contacts and making the first steps into the market, bringing new joint projects to the company and opening real business opportunities.

Puu- ja turvetuhkan hyötykäyttökelpoisuuteen vaikuttavat tekijät pienillä polttolaitoksilla

Energiantuotannossa syntyvä tuhka voi olla laadultaan hyvin vaihtelevaa ja laadunvaihtelulle on haastavaa löytää yksiselitteistä syy-seuraussuhdetta. Ympäristönsuojelulainsäädäntö ja taloudelliset intressit ohjaavat tuhkantuottajia etsimään tuhkalle sopivia hyötykäyttökohteita, ja sen vuoksi tuhkan laatuun ja hyötykäyttökelpoisuuteen vaikuttavia tekijöitä on tarpeen selvittää. Tässä diplomityössä on tutkittu pienissä, alle 50 MW:n polttolaitoksissa syntyvää tuhkaa. Tavoitteena oli selvittää, kuinka tuhkan hyötykäyttökelpoisuuteen voidaan vaikuttaa. Tutkimuksen kohteena oli polttoainekoostumuksen, poltto-olosuhteiden ja tuhkan jälkikäsittelyn vaikutus tuhkassa olevien haitta-aineiden pitoisuuksiin ja liukoisuuksin. Työhön sisältyi myös aiemmin tehtyjen tuhka-analyysien tarkastelu sekä tuhkakokeet kahdella kohderyhmään kuuluvalla laitoksella. Työssä todettiin lentotuhkan haitta-ainepitoisuuksien ja -liukoisuuksien olevan keskimäärin korkeampia kuin pohjatuhkan vastaavien, ja että tyypillisesti arinakattilan tuhkien haitta-aineet ylittävät useammin hyötykäyttökelpoisuuden raja-arvoja kuin kuplaleijupetikattilan tuhkien. Lisäksi havaittiin metsätähdehaketuhkan kelpaavan useammin hyötykäyttöön kuin rankahaketuhkan.

Marketing a Mobile Application in a Highly Competitive Global Marketplace

The purpose of this research was to study the marketing of mobile applications. The main objective was to find out what are the most efficient ways of marketing to increase the sales for a mobile application within a highly competitive marketplace. The marketplaces, app stores, are studied from the perspective of size, ease of entry, competition and customers and their purchasing process. The study also includes research on what are some of the main marketing methods used in mobile app marketing in general. The study consists of two parts, theoretical and empirical research. Theoretical research was done by studying past scientific research on the chosen subjects. As the subject is very new, the research was also extended to other publications from the field of mobile technology. The empirical part was done through interviews and empirical experiments with a case-company, which were used to answer the main objective of this study. These experiments showed that the chosen methods of mobile app marketing, app store optimization, localization and selected social media marketing activities, created the most sales when used together. Positive results were seen also when the activities were conducted by themselves, but together they were able to push the case company to their all time best results. However the key to succeeding and hitting high positions in the app store rankings would most likely require creating a solid marketing strategy, trying out other marketing activities alongside the ones used here, without forgetting to stay on top of mobile technology trends.

Yrityksen raportointitehtävien keskittäminen palvelukeskukseen, case-tutkimus

Pro Gradu –tutkielman tarkoituksena on ollut selvittää tämän hetken yritysmaailman yhtä keskeisintä aihetta, tehtävien keskittämistä palvelukeskukseen. Yrityksen tekemään päätökseen ovat vaikuttaneet useat eri tekijät, joista kiristyvä kilpailu ja toimintaympäristön muutokset ovat olleet merkittävimmät. Muutosprosessin läpivieminen vie aikaa ja siihen tulisi valmistautua huolella, sillä prosessiin liittyy useita eri vaiheita. Toimintojen organisointi ja muutosjohtaminen muodostavat tutkimuksen teoriapohjan. Tutkimus on laadullinen tutkimus, jonka aineisto on kerätty haastatteluiden ja havainnoinnin avulla. Tutkimus tehtiin eräässä kansainvälisessä yrityksessä, sen yhden liiketoiminta-alueen ja yhden toimintayksikön osalta. Tutkimustuloksista voitiin havaita, että tehtävien keskittäminen palvelukeskukseen koostui useasta vaiheesta. Se koettiin hyväksi ja onnistuneeksi toimintatavaksi. Tehtävien keskittämisprosessiin liittyy hyötyjä ja haasteita, näiden osalta tutkimustuloksissa löytyi yhteneviä tekijöitä aiempien tutkimusten ja kirjallisuusmateriaalin kanssa. Tutkimustulokset osoittivat, että muutosjohtaminen noudatteli tunnettua vaiheistusmallia. Muutosjohtamiseen liittyy merkittävästi ihmisten ja organisaation käyttäytyminen, joka vaikuttaa muutosprosessin onnistuneeseen läpiviemiseen. Ihmiset kokevat muutoksen eri tavoin ja aluksi vastustavat uutta tilannetta.
