Since the introduction of automatic orbital welding in pipeline application in 1961, significant improvements have been obtained in orbital pipe welding systems. Requirement of more productive welding systems for pipeline application forces manufacturers to innovate new advanced systems and welding processes for orbital welding method. Various methods have been used to make welding process adaptive, such as visual sensing, passive visual sensing, real-time intelligent control, scan welding technique, multi laser vision sensor, thermal scanning, adaptive image processing, neural network model, machine vision, and optical sensing. Numerous studies are reviewed and discussed in this Masters thesis and based on a wide range of experiments which already have been accomplished by different researches the vision sensor are reported to be the best choice for adaptive orbital pipe welding system. Also, in this study the most welding processes as well as the most pipe variations welded by orbital welding systems mainly for oil and gas pipeline applications are explained. The welding results show that Gas Metal Arc Welding (GMAW) and its variants like Surface Tension Transfer (STT) and modified short circuit are the most preferred processes in the welding of root pass and can be replaced to the Gas Tungsten Arc Welding (GTAW) in many applications. Furthermore, dual-tandem gas metal arc welding technique is currently considered the most efficient method in the welding of fill pass. Orbital GTAW process mostly is applied for applications ranging from single run welding of thin walled stainless tubes to multi run welding of thick walled pipes. Flux cored arc welding process is faster process with higher deposition rate and recently this process is getting more popular in pipe welding applications. Also, combination of gas metal arc welding and Nd:YAG laser has shown acceptable results in girth welding of land pipelines for oil and gas industry. This Masters thesis can be implemented as a guideline in welding of pipes and tubes to achieve higher quality and efficiency. Also, this research can be used as a base material for future investigations to supplement present finding.

In 2011 China became the worlds second largest economy overtaking Japan. With its rapidly growing middle class buying diverse goods from consumption products to sophisticated technology and luxury products, it is also the fastest growing export market in the world. The purpose of this study is to examine what types of market entry modes Finnish SMEs use in China, which factors affect on their decisions and whether they have switched or combined the strategies after entering China. The goal is to understand the relevance of the entry mode choice related to the internationalization process and to evaluate how well it suits the Chinese business environment. The empirical part of the study is a semi structured qualitative analysis of six case companies that represent different industry fields. The cases were selected based on the recent literature about the Finnish industry fields China is interested in to gain knowledge and expertise from. Companies included in the study are an architect office, two pharmaceutical development companies, an ICT company, a plastic mechanics company and a clean tech company. The results of this study indicated that the market entry patterns of Finnish SMEs in China differ from each other based on the factors related to companys background, mode concerns and Chinese market influences.

This study focuses on observing how Finnish companies execute their new product launch processes. The main objective was to find out how entry timing moderates the relationship between launch tactics (namely product innovativeness, price and emotional advertising) and new product performance (namely sales volume and customer profitability). The empirical analysis was based on data collected in Lappeenranta University of Technology. The sample consisted of Finnish companies representing different industries and innovation activities. Altogether 272 usable responses were received representing a response rate of 37.67%. The measures were first assessed by using exploratory factor analysis (EFA) in PASW Statistics 18 and then further verified with confirmatory factor analysis (CFA) in LISREL 8.80. To test the hypotheses of the moderating effects of entry timing, hierarchical regression analysis was used in PASW Statistics 18. The results of the study revealed that the effect of product innovativeness on new product sales volume is dependent on entry timing. This implies that companies should carefully consider what would be the best time for entering the market when launching highly innovative new products. The results also depict a positive relationship between emotional advertising and new product sales volume. In addition, partial support was found for a positive relationship between pricing and new product customer profitability.

<b>Lhikentt- ja kaukokenttmikroskopian yhdistminen: Uusi korkearesoluutioinen menetelm nanokuvantamiseen.</b> Osteoporoosi on sairaus, jossa luun uudistumisprosessi ei ole en tasapainossa. Uuden luun muodostuminen on hitaampaa johtuen osteoblastien laskeneesta aktiivisuudesta. Yksi keino est osteoporoosin synty on est osteoklastien sitoutuminen luun pinnalle, jolloin ne eivt aloita luun symisprosessia. Tmn Pro gradu -tutkielman tarkoituksena on luoda uusi tykalu osteoklastien sitoutumisen tutkimiseen samanaikaisesti fluoresenssi- ja atomivoimamikroskoopilla. Tt tarkoitusta varten yhdistettiin atomivoimamikroskooppi sek STED mikroskooppi. Kirjallisuuskatsauksessa kydn lpi yksityiskohtaisesti molempien mikroskooppitekniikoiden teoriat. Kokeellisessa osiossa esitetn kytetyt metodit ja alustavat tulokset uudella systeemill. Lisksi keskustellaan lyhyesti kuvan analysoinnista ImageJohjelmalla. Konfokaalisen fluoresenssimikroskoopin ja atomivoimamikroskoopin yhdistelm on keksitty jo aikaisemmin, mutta tavallisen konfokaalimikroskoopin erottelukyvyn raja on noin 200 nanometri johtuen valon diffraktioluonteesta. Yksityiskohdat eivt erotu, jos ne ovat pienempi kuin puolet kytettvst aallonpituudesta. STED mikroskooppi mahdollistaa fluoresenssikuvien taltioimisen solunsisisist prosesseista 50 nanometrin lateraalisella erotuskyvyll ja atomivoimamikroskooppi antaa topografista tietoa nytteest nanometrien erotuskyvyll. Biologisia nytteit kuvannettaessa atomivoimamikroskoopin erotuskyky kuitenkin huononee ja yleens saavutetaan 30-50 nanometrin erotuskyky. Kuvien kerrostaminen vaatii vertauspisteit ja tt varten kytettiin atomivoimamikroskoopin krjen tunnistamista ja referenssipartikkeleita. Kuva-analysointi suoritettiin ImageJ-kuvanksittelyohjelmalla. Tuloksista nhdn, ett referenssipartikkelit ovat hyvi, mutta niiden sijoittaminen tarkasti tietylle kohdealueelle on hankalaa nanoskaalassa. Tst johtuen krjen havaitseminen fluoresenssikuvassa on parempi metodi. Atomivoimamikroskoopin krki voidaan pllyst fluoresoivalla aineella, mutta tm lis krjen aiheuttamaa konvoluutiota mittausdataan. Mys valon takaisinsirontaa krjest voidaan tutkia, jolloin konvoluutio ei lisnny. Ensimmisten kuvien kerrostamisessa kytettiin hyvksi fluoresoivalla aineella pllystetty krke ja lopputuloksessa oli vain 50 nanometrin yhteensopimattomuus fluoresenssi- ja topografiakuvan kanssa. STED mikroskoopin avulla nhdn leimattujen proteiinien tarkat sijainnit tiettyn ajankohtana elvn solun sisll. Samaan aikaan pystytn kuvantamaan solun fyysisi muotoja tai mitata adheesiovoimia atomivoimamikroskoopilla. Lisksi voidaan kytt funktinalisoitua krke, jolla voidaan laukaista signalointitapahtumia solun ja soluvliaineen vlill. Sitoutuminen soluvliaineeseen voidaan rekisterid samoin kuin adheesiomediaattorien sijainnit sitoutumisalueella. Nm dynaamiset havainnot tuottavat uutta informaatiota solun signaloinnista, kun osteoklasti kiinnittyy luun pintaan. Tm teknologia tarjoaa uuden nkkulman monimutkaisiin signalointiprosesseihin nanoskaalassa ja tulee ratkaisemaan lukemattoman mrn biologisia ongelmia.

The soybean is important to the economy of Brazil, so the estimation of the planted area and the production with higher antecedence and reliability becomes essential. Techniques related to Remote Sensing may help to obtain this information at lower cost and less subjectivity in relation to traditional surveys. The aim of this study is to estimate the planted area with soybean culture in the crop of 2008/2009 in cities in the west of the state of Paran, in Brazil, based on the spectral dynamics of the culture and through the use of the specific system of analysis for images of Landsat 5/TM satellite. The obtained results were satisfactory, because the classification supervised by Maximum Verisimilitude - MaxVer along with the techniques of the specific system of analysis for satellite images has allowed an estimate of soybean planted area (soybean mask), obtaining values ​​of the metrics of Global Accuracy with an average of 79.05% and Kappa Index over 63.50% in all cities. The monitoring of a reference area was of great importance for determining the vegetative phase in which the culture is more different from the other targets, facilitating the choice of training samples (ROIs) and avoiding misclassifications.

RESUMO O Estado do Paran caracteriza-se por uma grande variabilidade de pocas de semeadura (DS) e, consequentemente, pelo desenvolvimento mximo vegetativo (DMDV), colheita (DC) e ciclo (CI) para a cultura da soja. O objetivo deste trabalho foi estimar essas datas para o perodo de primavera-vero do ano-safra de 2011/2012, por meio de sries temporais de imagens do ndice de Vegetao Realado (do ingls Enhanced Vegetation Index - EVI) do sensor Modis (Moderate Resolution Imaging Spectroradiometer). Gerou-se um perfil espectrotemporal mdio de EVI, considerando todos os pixels mapeados como soja dentro de cada municpio. Estes dados serviram de entrada no software Timesat para estimar os decndios do ciclo da cultura (DS, DMDV, DC e CI) por municpios. Os resultados mostraram que existe grande variabilidade de datas de plantio em diferentes mesorregies do Estado. Verificaram-se tambm divergncias entre os resultados encontrados e os dados oficiais de DS e DC. A maior parte da semeadura (65,16%) esteve entre o terceiro decndio de outubro e o primeiro decndio de novembro. A maior parte da rea de soja do Estado do Paran (65,46%) teve seu DMDV em janeiro e colheita em maro (53,92%).
