Capital Structure and Firm Growth: R&D Intensive Companies

The purpose of this study is to examine and explain firm`s growth impact on capital structure decision-making in research and development intensive companies. Many studies claim that R&D has a pivotal impact on capital structure decisions, but corporate finance theories have often failed to explain these observed patterns. As sales growth is an important concept and objective for R&D firms, it is logical to assume that it plays a vital role in capital structure decisions. This study applies nomothetic research approach. The theoretical part employs a formal conceptual analysis in order to develop the propositions that are tested with empirical data. The empirical part consists of the analysis of three companies; the data is obtained from the annual reports over the period 2003 – 2008. The companies operate in IT- or ICT-industry and are publicly listed. The method for analyzing the case data is based on the financial indicators, which are obtained from the financials of the case companies. These economic indicators describe the capital structure and the financial decision-making of the firms. The method relates to the quantitative studies. Yet, this study extends the analysis beyond the indicators. Specifically, this study addresses the question of what is behind the economic indicators, therefore combining aspects of quantitative and qualitative analysis. The firms examined in this study seem to prefer internal finance during growth. However, external finance seems to be a catalyst for sales growth. Firms strongly prefer equity financing. In growth, the use of equity per capital either increases or stays in a constant level. Over the period 2003 – 2008, the firms were often associated to equity related transactions and short-term debt. Short-term debt was used as a substitute of long-term debt and equity. The case firms also adjusted their capital structure – these adjustments were carried out with short-term debt or equity. The case data also provides implications for the growth signal theory that was developed in this study. Based on the econometric indicators, arguments can be made that equity investors are `attracted` to growing R&D firms. This is because growth helps investors perceive the true type of firm. The findings of this study are best explained by the trade-off theory and the pecking order theory. These corporate finance theories are considered as mainstream. Little support can be found to the implications of the signaling theory and market timing theory.

Perusteollisuus muuttuvassa toimintaympäristössä 2000 -2030: pääoman ja työvoiman tarve

The aim of the current study is to consider the need of capital and labour in Finnish basic industry within the next thirty years. The connection between capital and labour need of basic industry in the 1980's and 1990's is reviewed by using financial statements. A model of the relationship between investments and rate is built and the future need of labour in basic industry is outlined. The model about the profitability of work reducing investments when the rate varies describes the past development in companies. In Finland automation and advanced production technology have made it possible to replace work with capital in a large scale. In basic industry the need for capital can be forecasted to grow quicker than the need for labour. Economies of scale in the use of labour can be attained, because in the future one consolidated company will employ less people than two individual firms before.

Laadun kehittäminen suomalaisissa yrityksissä

Laadun ja sen kehittämisen sisältö on ollut jatkuvassa muutostilassa. Laatuajattelu on laajentunut käsittämään yhä suuremman osan organisaatioiden toiminnasta. Laadun kehittämisessä on jatkuvasti otettu käyttöön uusi kehittämiskeinoja. Laaja-alaisesti organisaation toimintaan kytkeytyvistä keinoista tunnetuimpia ovat erilaiset laadunhallintajärjestelmät ja itsearviointi eri kriteeristöjen avulla. Tämän tutkimuksen tavoitteina olivat: a) etsiä motiiveja, minkä vuoksi yritykset ovat alkaneet kehittää laatuaan, b) tutkia total quality management (TQM) -ajattelun soveltamisen syvällisyyden vaikutuksia, c) selvittää laadunkehittämistyön ajallisen keston vaikutuksia, ja d) saada kokonaiskuva keskeisimpien laadun kehittämiskeinojen toteutuksesta ja menestyksellisyydestä. Työn teoriaosassa paneuduttiin laatu-käsitteeseen yritystoiminnassa, laatu- ja TQM-ajattelun sisältöön sekä laadun kehittämisen johtamiseen. Lisäksi tutkittiin keskeisimpiä laadun kehittämisen keinoja, joita olivat mm. ihmisten toiminta, laadunhallintajärjestelmät, itsearvioinnit, toimintaprosessien kehittäminen, asiakas- ja toimittajayhteistyö. Tutkimuksen empiirisessä osassa tutkittiinem. laadun kehittämiseen liittyviä asioita suomalaisissa yrityksissä. Aineisto kerättiin haastattelemalla yritysten laadun kehittämisestä vastaavia henkilöitä 24 yrityksessä. Tulosten esittämisessä hyödynnettiin tilastollisia tutkimusmenetelmiä kvalitatiivisten menetelmien ohella. Tässä aineistossa asiakasvaatimukset ja oma kehityshalu nousivat yleisimmiksi tärkeimmistä laadun kehittämisen aloitusmotiiveista. Mikään tärkeimmistä aloitusmotiiveista ei ollutkuitenkaan johtanut selkeästi ylivoimaisimpaan menestymiseen myöhemmin. TQM-ajattelun laaja-alainen soveltaminen johti laadun kehittämisen kannalta positiiviseen suuntaan. Pisimpään laatuaan kehittäneet yritykset olivat suuria ja kansainvälisesti suuntautuneita. Pelkkä kehitystyön ajallinen kesto näkyi vain vähän kehittämisen eri osa-alueilla. Laadun kehittämistyön menetyksellisyyden kannalta positiivia asioita olivat: henkilöstön aktiivisuus, itsearviointien hyödyntäminen, toimintaprosessien kuvaaminen ja kehittäminen, sekä asiakas- ja toimittajayhteistyö. Laadun kehittämiseen kannattaa ottaa aktiivisesti mukaankoko organisaation henkilöstö. Itsearviointien käytöllä on mahdollista kehittääorganisaatiota laaja-alaisesti. Niin asiakkaat kuin toimittajat kannattaa ottaaaktiivisesti mukaan kehittämistoimintaan. Se on kaikkien osapuolien yhteinen etu.

Digitaalinen osaamisen kehittäminen osana henkilöstökoulutusta

Tieto- ja viestintätekniikan kehittyminen on muuttanut työn luonnetta monella tavalla ja työelämän jatkuva muutos ja joustavuuteen pyrkiminen edellyttävät uusien tietojen ja taitojen hankkimista. Verkko-opetus, verkko-opiskelu ja verkko-oppiminen näyttävät tarjoavat uusia ulottuvuuksia henkilöstökoulutukseen. Tämän diplomityön tarkoituksena on tutkia voidaanko digitaalisella osaamisen kehittämisellä tukea yrityksen henkilöstökoulutusta ja henkilöstöä opiskelussa ja oppimisessa? Osaaminen on strateginen kysymys ja sen kehittämisessä pyritään yrityksissä aiempaa pitkäjänteisempään ja kokonaisvaltaisempaan toimintatapaan. Digitaalinen osaamisen kehittäminen oikein toteutettuna näyttää vahvistavan henkilöstön osaamistasoa. Tekniset apuvälineet eivät ehkä koskaan tule korvaamaan kokemusta ja työssä oppimista, silti ne näyttävät helpottavat tiedonkulkua ja ovat apuna osaamisen kehittämisessä. Kuvitelma verkko-opintojen helppoudesta, täysin ajasta ja paikasta riippumattomana, sekä itsenäisestä opiskelusta on harhaa. Verkkokoulutuksen suurena haasteena on sen soveltaminen järkevällä tavalla organisaation toimintakulttuuriin ja toimintatapoihin. Ajanoloon verkko-opiskelu saattaa muuttua osaksi työtä, mutta asenteiden muokkaamisessa on vielä paljon tekemistä. Yritysten johdon tulee näyttää tietä ja toimia esimerkkinä uusien toimintatapojen käyttöönotossa.

Working capital management in the value chain of automotive industry

The objective of this Master’s thesis is to examine working capital management in the automotive industry in years 2006-2008. The study is conducted by the analysis of financial statements. The sample consists of 65 companies that represent different stages in the value chain of automotive industry beginning from raw material suppliers and ending to car dealers. Working capital management is studied by the cash conversion cycle (CCC). The results show that the average CCC of the value chain is 67 days. Car manufacturers had the longest CCC, 106 days, whereas the CCC of oil companies was the shortest, 22 days. The findings suggest that the cycle time of working capital usually follows the cycle time of inventories, since the changes in cycle times of accounts receivable and payable compensate each other. Improvements in working capital management could be achieved by sharing more accurate information in the chain for example about inventory levels and order points of customer. It could also be discussed within the automotive industry, if the long credit periods, which tie up working capital, are really needed. New technologies enable faster payments, which would reduce the cash conversion cycles, improve the profitability of companies, and increase the competitiveness of the value chain. Working capital should not be reduced at the expense of value chain partners, because nowadays the competition is rather between the value chains than between the companies. Similar research design is applied earlier to study working capital management in the value chain of pulp and paper industry. Even if the industries and the structures of the chains differ from each other, results were surprisingly similar. In future research, working capital management in other industries’ value chains could still be studied and compared to previous studies. ICT industry, for example, could be an interesting object.

Yhteiskuntavastuuraportointi kansainvälisissä öljy-yhtiöissä vuonna 2013

Tutkimuksen tavoitteena oli selvittää, kuinka suuret yhdysvaltalaiset ja eurooppalaiset öljy-yhtiöt raportoivat yhteiskuntavastuustaan vuonna 2013 sekä kuinka laadukasta ja laaja-alaista raportointi oli. Yhtiöiden raportointia tutkittiin GRI-viitekehyksen taloudellisen, sosiaalisen ja ympäristövastuun näkökulmasta. Yritysten raportointia arvioitiin myös maa-alue- sekä liikevaihtokohtaisesti tutkien, voidaanko eroja näiden suhteen löytää. Lisäksi raportoinnin laatua analysoitiin yritysten asettamien yhteiskuntavastuutavoitteiden määrän kautta. Tutkimuksessa selvitettiin myös GRI-viitekehyksen sekä muiden yleisimpien yhteiskuntavastuuviitekehyksien käyttöä tutkimusyrityksissä. Tutkimusaineisto koostui 30:stä listatusta yhdysvaltalais- ja eurooppalaisyrityksen vuoden 2013 yhteiskuntavastuuraporteista. Tutkimustapana käytettiin kvalitatiivista sisällönanalyysiä. GRI-viitekehys oli tutkimusyrityksissä käytetyin viitekehys. Tulosten mukaan eurooppalaisyritykset raportoivat pääsääntöisesti laadukkaasti vastuustaan ja raportointi oli Euroopassa selkeästi Yhdysvaltoja laadukkaampaa kaikilla vastuun osa-alueilla. Tutkimusyrityksen koko vaikutti raportoinnin laajuuteen sekä määrään vain Yhdysvalloissa. Suuremmat yhdysvaltalaisyritykset raportoivat pienempiä paremmin. Tulosten perusteella yrityksen koko ei vaikuttanut tavoitteiden määrään. Maantieteellinen sijainti vaikutti raportoinnin laatuun. Eurooppalaisyritykset raportoivat laajemmin, laadukkaammin sekä asettivat tavoitteita huomattavasti yhdysvaltalaisia yrityksiä useammin ja enemmän kaikilla vastuun osa-alueilla.

Catching up with competitiveness in emerging markets – An analysis of the role of the firm’s technology management strategies

Emerging markets have experienced rapid economic growth, and manufacturing firms have had to face the effects of globalisation. Some of the major emerging economies have been able to create a supportive business environment that fosters innovation, and China is a good example of a country that has been able to increase value-added investments. Conversely, when we look at Russia, another big emerging market, we witness a situation in which domestic firms struggle more with global competitiveness. Innovation has proven to be one of the most essential ingredients for firms aiming to grow and become more competitive. In emerging markets, the business environment sets many constraints for innovation. However, open strategic choices in new product development enable companies in emerging markets to expand their resource base and capability building. Networking and close inter-firm cooperation are essential in this regard. In this dissertation, I argue that technology transfer is one of the key tools for these companies to become internationally networked and to improve their competitiveness. It forces companies to reach outside the company and national borders, which in many cases, is a major challenge for firms in emerging markets. This dissertation focuses on how companies can catch up with competitiveness in emerging markets. The empirical studies included in the dissertation are based on analyses of survey data mainly of firms and their strategies in the Russian manufacturing industry. The dissertation contributes to the current strategic management literature by further investigating technology management strategies in manufacturing firms in emerging markets and the benefits of more open approaches to new product development and innovation.

Corporate Social Responsibility in the Oil and Gas Industry: Environmental Management Systems as a Source of Sustainable Development

The environmental aspect of corporate social responsibility (CSR) expressed through the process of the EMS implementation in the oil and gas companies is identified as the main subject of this research. In the theoretical part, the basic attention is paid to justification of a link between CSR and environmental management. The achievement of sustainable competitive advantage as a result of environmental capital growth and inclusion of the socially responsible activities in the corporate strategy is another issue that is of special significance here. Besides, two basic forms of environmental management systems (environmental decision support systems and environmental information management systems) are explored and their role in effective stakeholder interaction is tackled. The most crucial benefits of EMS are also analyzed to underline its importance as a source of sustainable development. Further research is based on the survey of 51 sampled oil and gas companies (both publicly owned and state owned ones) originated from different countries all over the world and providing reports on sustainability issues in the open access. To analyze their approach to sustainable development, a specifically designed evaluation matrix with 37 indicators developed in accordance with the General Reporting Initiative (GRI) guidelines for non-financial reporting was prepared. Additionally, the quality of environmental information disclosure was measured on the basis of a quality – quantity matrix. According to results of research, oil and gas companies prefer implementing reactive measures to the costly and knowledge-intensive proactive techniques for elimination of the negative environmental impacts. Besides, it was identified that the environmental performance disclosure is mostly rather limited, so that the quality of non-financial reporting can be judged as quite insufficient. In spite of the fact that most of the oil and gas companies in the sample claim the EMS to be embedded currently in their structure, they often do not provide any details for the process of their implementation. As a potential for the further development of EMS, author mentions possible integration of their different forms in a single entity, extension of existing structure on the basis of consolidation of the structural and strategic precautions as well as development of a unified certification standard instead of several ones that exist today in order to enhance control on the EMS implementation.

Managing innovation in oil and gas companies: A proposed framework for the management of innovation at Ecopetrol S.A.

Actually, the term innovation seems to be one of the most used in any kind of business practices. However, in order to get value from it, companies need to define a systematic and structured way to manage innovation. This process can be difficult and very risky since it is associated with the development of firm´s capabilities which involves human and technical challenges according to the context of a firm. Additionally, it seems not to exist a magic formula to manage innovation and what may work in a company may not work in another, even though in the same type of industry. In this sense, the purpose of this research is to identify how the oil and gas companies can manage innovation and what are the main elements, their interrelations and structure, required for managing innovation effectively in this critical sector for the world economy. The study follows a holistic single case study in a National Oil Company (NOC) of a developing country to explore how innovation performs in the industry, what are the main elements regarding innovation management and their interactions according to the nature of the industry. Contributory literature and qualitative data from the case study company (with the use of non-standardized interviews) is collected and analyzed. The research confirms the relevance and importance of the definition and implementation of an innovation framework in order to ensure the generation of value and organize as well as guide the efforts in innovation done by a firm. In this way based on the theoretical background, research´s findings, and in the company´s innovation environment and conditions, a framework for managing innovation at the case study company is suggested. This study is one of the few, if not only one, that has reviewed the way as oil and gas companies manage innovation and its practical implementation in a company from a developing country. Both researchers and practitioners will get a photograph of understanding innovation management in the oil and gas industry and its growing necessity in the business world. Some issues have been highlighted, so that future study can be focused in those directions. In fact, even though research on innovation management has significantly grown, there are still many issues that need to be addressed to get insight about managing innovation in various contexts and industries. Studies are mostly performed in the context of large firms and in developed countries, so then research in the context of developing countries is still almost an untouched area, especially in the oil and gas industry. Finally, from the research it seems crucial to explore the effect of some innovation-related variables such as: open innovation in third world economies and in state-own companies; the impact of mergers and acquisitions in innovation performance in oil and gas companies; value measurement in the first stages of the innovation process; and, development of innovation capabilities in companies from developing nations.

Logistics Development in Finnish and Swedish Companies with Respect of Russia and Four Asian Countries: Traffic Flow and Warehousing Analysis from Current Situation and Likely Development Trends

On selvää, että tänä päivänä maailmankaupan painopiste on hiljalleen siirtymässä Aasiaan ja varsinkin Kiina on ollut huomion keskipisteessä. Erityisesti valmistavien yritysten perspektiivistä muutos on ollut merkittävä ja tämä tosiasia kasvattaa yrityksissä paineita luoda kustannustehokkaita toimitusketjuratkaisuja,joiden vasteaika on mahdollisimman lyhyt. Samaan aikaan kun tarkastellaan kuljetusvirtoja, huomattaan että maanosien välillä on suuri epätasapaino. Tämä on enimmäkseen seurausta suurten globaalisti toimivien yritysten toimitusketjustrategioista. Useimmat näistä toimijoista optimoivat verkostonsa turvautumalla 'paikalliseen hankintaan', jotta he voisivat paremmin hallita toimitusketjujaan ja saada näitä reagointiherkimmiksi. Valmistusyksiköillä onkin monesti Euroopassa pakko käyttää kalliita raaka-aineita ja puolivalmisteita. Kriittisiksi tekijöiksi osoittautuvat kuljetus- ja varastointikustannukset sekä näiden seurauksena hukka-aika, joka aiheutuu viivästyksistä. Voidakseen saavuttaa optimiratkaisun, on tehtävä päätös miten tuotteet varastoidaan: keskitetysti tai hajautetusti ja integroida tämä valinta sopivien kuljetusmuotojen kanssa. Aasiasta Pohjois-Eurooppaan on halpaa käyttää merikuljetusta, mutta operaatio kestää hyvin pitkään - joissain tapauksessa jopa kahdeksan viikkoa. Toisaalta lentokuljetus on sekä kallis että rajoittaa siirrettävien tuotteiden eräkokoa.On olemassa kolmaskin vaihtoehto, josta voisi olla ratkaisuksi: rautatiekuljetus on halvempi kuin lentokuljetus ja vasteajat ovat lyhyemmät kuin merikuljetuksissa. Tässä tutkimuksessa tilannetta selvitetään kyselyllä, joka suunnattiin Suomessa ja Ruotsissa toimiville yrityksille. Tuloksien perusteella teemme johtopäätökset siitä, mitkä kuljetusmuotojen markkinaosuudet tulevat olemaan tulevaisuudessa sekä luomme kuvan kuljetusvirroista Euroopan, Venäjän, Etelä-Korea, Intian, Kiinan ja Japanin välillä. Samalla on tarkoitus ennakoida sitä, miten tarkastelun kohteena olevat yritykset aikovat kehittää kuljetuksiaan ja varastointiaan tulevien vuosien aikana. Tulosten perusteella näyttää siltä, että seuraavan viiden vuoden kuluessa kuljetuskustannukset eivät merkittävissä määrin tule muuttuman ja meri- sekä kumipyöräkuljetukset pysyvät suosituimpina vaihtoehtoina.Kuitenkin lentokuljetusten osuus laskee hiukan, kun taas rautatiekuljetusten painotus kasvaa. Tulokset paljastavat, että Kiinassa ja Venäjällä kuljetettava konttimäärä kasvaa; Intiassa tulos on saman suuntainen, joskaan ei niin voimakas. Analyysimme mukaan kuljetusvirtoihin liittyvä epätasapaino säilyy Venäjän kuljetusten suhteen: yritykset jatkavat tulevaisuudessakin vientiperusteista strategiaansa. Varastoinnin puolella tunnistamme pienemmän muutoksen, jonka mukaan pienikokoisten varastojen määrät todennäköisesti vähenevät tulevaisuudessa ja kiinnostus isoja varastoja kohtaan lisääntyy. Tässä kohtaa on mainittava, että suomalaisilla yrityksillä on enemmän varastoja Keski- ja Itä-Euroopassa verrattuna ruotsalaisiin toimijoihin, jotka keskittyvät selkeämmin Länsi-Euroopan maihin. Varastoja yrityksillä on molemmissa tapaukissa paljolti kotimaassaan. Valitessaan varastojensa sijoituskohteita yritykset painottavat seuraavia kriteereitä: alhaiset jakelukustannukset, kokoamispaikan/valmistustehtaan läheisyys, saapuvan logistiikan integroitavuus ja saatavilla olevat logistiikkapalvelut. Tutkimuksemme lopussa päädymme siihen, että varastojen sijoituspaikat eivät muutu satamien rakenteen ja liikenneyhteyksien takia kovinkaan nopeasti.

Development of Russian Ports in The Gulf of Finland

Russia has been one of the fastest developing economic areas in the world. Based on the GDP, the Russian economy grew evenly since the crisis in 1998 up till 2008. The growth in the gross domestic product has annually been some 5–10%. In 2007, the growth reached 8.1%, which is the highest figure after the 10% growth in 2000. Due to the growth of the economy and wage levels, purchasing power and consumption have been strongly increasing. The growing consumption has especially increased the imports of durables, such as passenger cars, domestic appliances and electronics. The Russian ports and infrastructure have not been able to satisfy the growing needs of exports and imports, which is why quite a large share of Russian foreign trade is going through third countries as transit transports. Finnish ports play a major role in transit transports to and from Russia. About 15% of the total value of Russian imports was transported through Finland in 2008. The economic recession that started in autumn 2008 and continues to date has had an impact on the economic development of Russia. The export income has decreased, mainly due to the reduced world market prices of energy products (oil and gas) and raw minerals. Investments have been postponed, getting credit is more difficult than before, and the ruble has weakened in relation to the euro and the dollar. The imports are decreasing remarkably, and are not forecast to reach the 2008 volumes even in 2012. The economic crisis is reflected in Finland's transit traffic. The volume of goods transported through Finland to and from Russia has decreased almost in the same proportion as the imports of goods to Russia. The biggest risk threatening the development of the Russian economy over long term is its dependence on export income from oil, gas, metals, minerals and forest products, as well as the trends of the world market prices of these products. Nevertheless, it is expected that the GDP of Russia will start to grow again in the forthcoming years due to the increased demand for energy products and raw minerals in the world. At the same time, it is obvious that the world market prices of these products will go up with the increasing demand. The increased income from exports will lead to a growth of imports, especially those of consumer goods, as the living standard of Russian citizens rises. The forecasts produced by the Russian Government concerning the economic development of Russia up till 2030 also indicate a shift in exported goods from raw materials to processed products, which together with energy products will become the main export goods of Russia. As a consequence, Russia may need export routes through third countries, which can be seen as an opportunity for increased transit transports through the ports of Finland. The ports competing with the ports of Finland for Russian foreign trade traffic are the Russian Baltic Sea ports and the ports of the Baltic countries. The strongest competitors are the Baltic Sea ports handling containers. On the Russian Baltic Sea, these ports include Saint Petersburg, Kaliningrad and, in the near future, the ports of Ust-Luga and possibly Vyborg. There are plans to develop Ust-Luga and Vyborg as modern container ports, which would become serious competitors to the Finnish ports. Russia is aiming to redirect as large a share as possible of foreign trade traffic to its own ports. The ports of Russia and the infrastructure associated with them are under constant development. On the other hand, the logistic capacity of Russia is not able to satisfy the continually growing needs of the Russian foreign trade. The capacity problem is emphasized by a structural incompatibility between the exports and imports in the Russian foreign trade. Russian exports can only use a small part of the containers brought in with imports. Problems are also caused by the difficult ice conditions and narrow waterways leading to the ports. It is predicted that Finland will maintain its position as a transit route for the Russian foreign trade, at least in the near future. The Russian foreign trade is increasing, and Russia will not be able to develop its ports in proportion with the increasing foreign trade. With the development of port capacity, cargo flows through the ports of Russia will grow. Structural changes in transit traffic are already visible. Firms are more and more relocating their production to Russia, for example as regards the assembly of cars and warehousing services. Simultaneously, an increasing part of transit cargoes are sent directly to Russia without unloading and reloading in Finland. New product groups have nevertheless been transported through Finland (textile products and tools), replacing the lost cargos. The global recession that started in autumn 2008 has influenced the volume of Russian imports and, consequently, the transit volumes of Finland, but the recession is not expected to be of long duration, and will thus only have a short-term impact on transit volumes. The Finnish infrastructure and services offered by the logistic chain should also be ready to react to the changes in imported product groups as well as to the change in Russian export products in the future. If the development plans of the Russian economy are realized, export products will be more refined, and the share of energy and raw material products will decrease. The other notable factor to be taken into consideration is the extremely fast-changing business environment in Russia. Operators in the logistic chain should be flexible enough to adapt to all kinds of changes to capitalise on business opportunities offered by the Russian foreign trade for the companies and for the transit volumes of Finnish ports, also in the future.

Platform as a Service - new opportunities for software development companies

Today cloud computing is the next stage in development information-oriented society in field of information technologies. Great attention is paid to cloud computing in general, but the lack of scientific consideration to components brings to the problem, that not all aspects are well examined. This thesis is an attempt to consider Platform as a Service (a technology of providing development environment through the Internet) from divergent angles. Technical characteristics, costs, time, estimation of effectiveness, risks, strategies that can be applied, migration process, advantages and disadvantages and the future of the approach are examined to get the overall picture of cloud platforms. During the work literature study was used to examine Platform as a Service, characteristics of existent cloud platforms were explored and a model of a typical software development company was developed to create a scenario of migration to cloud technologies. The research showed that besides all virtues in reducing costs and time, cloud platforms have some significant obstacles in adoption. Privacy, security and insufficient legislation impede the concept to be widespread.

Development of a Radiometer Front End for Detection of Oil Spill on Sea Surface

Kaikki kappaleet säteilevät sähkömagneettista energiaa. Radiometreillä voidaan mitata tätä säteilyä, ja mittausten avulla voidaan kaukokartoituksessa analysoida monia ilmakehään ja maan pintaan liittyviä ilmiöitä. Säteilyä kerätään useimmiten radiometriin kytketyn antennin avulla. Mikroaaltoalueella säteilystä saatava teho on verrannollinen kohteen kirkkauslämpötilaan. Kirkkauslämpötila on puolestaan verrannollinen kohteen fyysiseen lämpötilaan materiaalin emissiivisyyden kautta. Emissiivisyys voi vaihdella suuresti eri pintojen ja materiaalien välillä. Näin ollen mittaamalla kohteen kirkkauslämpötilaa saadaan tietoa sen ominaisuuksista. Mikroaaltoradiometrin avulla voidaan havaita öljyläikkä meren pinnalta, sekä määrittää öljyläikän paksuus. Öljy muodostaa ohuen kalvon meren pinnalla. Ohuen kalvon ylä- ja alapinnasta heijastuneet aallot kulkevat eri matkan, jonka seurauksena muodostuu interferenssikuvio. Interferenssi on joko konstruktiivinen tai destruktiivinen riippuen heijastusten vaihe-erosta. Pistetaajuudella tästä seuraa kalvon paksuudesta riippuva sinimuotoinen emissiivisyys. Mallintamalla tämä ilmiö riittävän tarkasti voidaan radiometrin mittaamaa kirkkauslämpötilaa verrata mallinnettuun arvoon ja täten määrittää öljykerroksen paksuus. Tässä työssä esitetään kahden radiometrin suunnittelu ja testaus. Työ rajoittuu radiometrien alustavaan testausvaiheeseen. Radiometrit on suunniteltu 36,5GHz sekä 89GHz taajuuksille. Työn suurin kontribuutio on radiometrien etupään suunnittelussa ja testauksessa, kalibraatiomenetelmien kehittämisessä sekä kylmäkuorman suunnittelussa. Lisäksi työssä esitetään radiometrien systeemisuunnittelu sekä siihen liittyvät simulaatiot.

Carrier selection and management : A case study on Neste Oil Retail

Service provider selection has been said to be a critical factor in the formation of supply chains. Through successful selection companies can attain competitive advantage, cost savings and more flexible operations. Service provider management is the next crucial step in outsourcing process after the selection has been made. Without proper management companies cannot be sure about the level of service they have bought and they may suffer from service provider's opportunistic behavior. In worst case scenario the buyer company may end up in locked-in situation in which it is totally dependent of the service provider. This thesis studies how the case company conducts its carrier selection process along with the criteria related to it. A model for the final selection is also provided. In addition, case company's carrier management procedures are reflected against recommendations from previous researches. The research was conducted as a qualitative case study on the principal company, Neste Oil Retail. A literature review was made on outsourcing, service provider selection and service provider management. On the basis of the literature review, this thesis ended up recommending Analytic hierarchy process as the preferred model for the carrier selection. Furthermore, Agency theory was seen to be a functional framework for carrier management in this study. Empirical part of this thesis was conducted in the case company by interviewing the key persons in the selection process, making observations and going through documentations related to the subject. According to the results from the study, both carrier selection process as well as carrier management were closely in line with suggestions from literature review. Analytic hierarchy process results revealed that the case company considers service quality as the most important criteria with financial situation and price of service following behind with almost identical weights with each other. Equipment and personnel was seen as the least important selection criterion. Regarding carrier management, the study resulted in the conclusion that the company should consider engaging more in carrier development and working towards beneficial and effective relationships. Otherwise, no major changes were recommended for the case company processes.
