在技術快速變遷的環境中，如何迅速掌握與研發相關的情報以協助研發決策的制訂，已經成為企業重要的競爭優勢來源。近年來，由於電腦運算能力的快速提昇，使用電腦輔助企業自動、快速地從大量增加的科技資訊（特別是專利和論文）中淬取出攸關的資訊，就成為了近年來產業界和學術界積極研究的目標。 在眾多方法中，使用書目計量分析和專利分析方法是最引人注目的方法之一。使用書目計量分析和專利分析可以從龐大的論文和專利資訊中，快速瞭解科技發展的動態：包括瞭解科技發展的階段為何，熱門的科技領域為何，重要的作者和企業為何等等。然而，現階段的書目計量分析和專利分析雖然可以協助瞭解科技發展的全貌，對於科技發展下技術發明活動與科學研究活動的關聯性，以及不同的科技發展階段裡發明人和作者的動態關係，卻仍然缺少相關的研究。 因此，本研究提出以下三點研究問題： 1. 不同類型的論文作者和專利發明人的科學研究／技術發明活動，與技術發展階段的關聯性為何？ 2. 發明作者的技術發明／科學研究活動與一般發明人或作者的差異為何？ 3. 發明作者的技術發明活動與科學研究活動關係為何？ 針對以上的研究問題，本研究首先通過回顧相關文獻以建立分析發明人和作者的研究架構，再蒐集專利和論文的資料並依照架構的需要處理資料，最後進行分析與討論以得到研究結論。 本研究主要獲得以下三點研究結論： 1. 天才發明人是技術發展處於萌芽期時專利發明的要角，而關鍵發明人大多在技術發展進入成長期時才投入專利發明。至於頂尖作者，則在技術發展的萌芽期、成長期和成熟期都是論文發表的要角。 2. 關鍵發明人有很高的機會是頂尖作者，而發明作者如果不是關鍵發明人，則其專利發明的表現有略高的機會較其他發明人更差。 3. 大部份發明作者的專利發明活動在論文發表活動之後；但是關鍵發明人則較傾向先申請專利，再發表主題高度相關的論文。 / Mining information to improve corporate R&D decision making had been an important source of competitive advantage in the rapid changing technological environment. Recently, extracting relevant information quickly and automatically from massive amount of technological data (especially patent and scientific publications) with the aide of computer had become an active research area for both industrial and academic researchers due to ever-growing computing power. Among the methods of retrieving technological information, bibliometrics and patent analysis are two of the most attractive ones. Bibliometrics and patent analysis provide a quick way to capture the dynamics of technological development, including the stage of technological development, active technological research area and important researchers/corporates, etc. Although bibliometrics and patent analysis are helpful to understand the landscape of technological development, there still lacks researches about the relationship between scientific invention and research activities as well as the dynamics between patent inventors and publication authors along different stages of technological development. Hence, this research raises the following questions: 1. What is the relation between scientific research/invention activities and technological development stages for different categories of publication authors and patent inventors? 2. What is the difference of scientific research/invention activities between Inventor-Authors and other inventors/authors? 3. What is the relation between scientific research and invention activities of Inventor-Authors? This research reviews related researches to define a research framework connecting authors, inventors and technological development stages. Then patent and publication data are collected and processed based on the research framework. This research conclusion is made after analysis and discussion. Conclusion of the research includes the followings: 1. "Talent Inventors" play important role when the technological development is in "Emerging" stage, and "Key Inventors" starts patent inventions after the technological development enters "Growth" stage. "Top Authors" play important role across "Emerging", "Growth" and "Maturity" stages of technological development. 2. "Key Inventors" are more probable to be also "Top Author". "Inventor-Authors" who are not "Key Inventors" are more probably to perform worse than other inventors. 3. Most "Inventor-Authors" apply for patents after papers of highly related topics are published. But "Key Inventors" tend to apply for patents before papers of highly related topics are published.

A patent is an intellectual property right granted as a reward for the labours of the inventor so as to commercially exploit the invention in return for disclosure of the invention. The benefits of the patent system find perfect expression in the employment situation since the employer is better equipped to exploit the invention through provision of resources and capital whereas the employee is provided with an opportunity to develop his technical know-how. A comparative study of the laws pertaining to employee inventions in the United Kingdom, Federal Republic of Germany and the United States of America reveals a variety of approaches to the subject of employee inventions. The approach of the South African law on the subject is inadequate and legal reform is a necessity. The recommendations for such reform encapsulates a blend of the best features of each of the three national approaches to employee inventions. / Mercentile Law / LL. M. (Law)

Dendro Lift AB är ett företag som utvecklar och tillverkar lyftbockar för tunga lyft. Tillsammans med konstruktionsföretaget Mk3D tar Dendro Lift AB fram ett nytt koncept för en lyftbocksmodell till lyft av stödbenstruckar. Syftet med examensarbetet är att vidareutveckla lyftoket till lyftbocken LB2.5 genom att minska materialanvändningen och bereda plats för ett nytt damm- och petskydd. Målet med examensarbetet är att ta fram underlag för tillverkning av ett nytt lyftok som uppfyllde ställda krav. Vid genomförandet av examensarbetet gjordes en förstudie kring dimensioneringskraven, spänningar i skruvförband, utvärdering av spänningar i svetsar, finita elementmetoden och hållbar utveckling. Förstudien följdes av analyser och vidareutveckling av lyftoket med finita elementanalyser i mjukvaran ANSYS Workbench 17.2. Modeller togs fram i Autodesk Inventor Professional 2016. Resultatet visade att det nya lyftokets plåttjocklek kunde minskas från 15 mm till 10 mm och därmed reducerades materialanvändningen med cirka 66 kg. I det nya lyftoket bereddes även plats för en ny typ av damm- och petskydd. Slutsatsen blir att det gamla lyftoket är överdimensionerat och mindre material kan användas utan att funktionen i lyftoket försämras. / Dendro Lift AB is a company that develops and manufactures lifting jacks for heavy lifting. Along with the construction company Mk3D, Dendro Lift AB introduces a new concept for a lifting trestle designed to lift stackers. The aim of the thesis is to further develop the yoke fitted in the lifting jack LB2.5 by reducing its material use and make way for a new dust and finger protection. The goal of the thesis is to develop manufacturing plans for the production of a new lifting yoke that meets the applicable requirements. In the implementation of the thesis there was a preliminary study on the design requirements, tension in bolted joints, evaluation of stresses in welds, finite element method analysis and sustainable development. The pilot study was followed by analysis and further development of the yoke with finite element analysis in software ANSYS Workbench 17.2. Models were developed in Autodesk Inventor Professional 2016. The results showed that the plate thickness could be reduced from 15 mm to 10 mm in the new yoke and thus reduced material usage by about 66 kg. The new yoke was also prepared for a new type of dust and finger protection. The conclusion was that the old yoke is oversized and less material can be used without compromising the operation of the lifting jack.

The issue this master’s thesis discusses the cooling synchronous machines. Specifically, the calculation of cooling induction motor using the finite volume method. Using Autodesk Inventor will create a 3D model of a real electric machine, ie asynchronous motor and then ANSYS WORKBENCH perform system analysis CFX, based on the finite volume method. Furthermore, we realize the air speed measurements on a particular machine and the individual results obtained by measuring and calculating the actual compared with each other. The master’s thesis also deals marginally with closely related to it. For the same machine model, we apply the calculation of the temperature fields using the finite volume method and them perform a thermal analysis. Next, we can carry out the measurement of the temperature on the motor itself and calculate the measured values and the measured compare each other.

This thesis proposes to enlighten several channels that favor the emergence and the outcome of creative ideas and innovation in general amongst private firms, with a particular focus on European companies. The first chapter introduces the motivations related to this research, defines the research objectives and questions addressed by the dissertation and concludes with the outline and the contributions of the thesis. <p><p>The second chapter analyzes the financing constraints on R&D investments. The central question in this chapter is whether financing constraints can explain a part of the acknowledged R&D gap between Europe and the US. In order to address this question, a dataset is constructed on the basis of a compilation of R&D scoreboards. The findings of this chapter are based on a sensitivity analysis of R&D to cash flow using estimates of dynamic R&D equations. The relationship between the financing constraints on R&D and the age of the companies is analyzed in an additional set of results with parametric as well as non parametric estimations. European firms appear to be affected by financing constraints in the 2000s while this is not the case for the US companies. The age seems to affect negatively the R&D sensitivity for EU and US leading innovators, with higher sensitivities for old and low-tech EU firms than their US counterparts.<p><p>The third chapter is dedicated to the measuring of the knowledge production of R&D expenditures when they are disaggregated into the following components: intramural versus extramural expenditures, research versus development expenditures, product-oriented versus process-oriented, human capital versus investments. The sources of funding and the types of subcontractors are also considered. The main question of this chapter is whether the heterogeneity of R&D affects the technology performance of the companies, as measured by patent applications. A cross-sectional Belgian R&D survey conducted over 2004-2005 is used for the purpose of the analysis. Given the high dependency of the Belgian innovation system towards the foreign MNEs, a matching process was performed between Belgian R&D and patents related to Belgian inventors in order to capture the patents filed outside Belgium but related to inventions created by firms located in Belgium (i.e. subsidiaries of foreign groups). Estimates of the elasticity of the quantity of patents with respect to the components of R&D are provided. <p><p>The main question of the fourth chapter is whether the diversification strategies of the economic activities of the R&D leaders in Europe affect, positively or negatively, the performance of their R&D activities. An original approach is proposed on the basis of the analysis of the subsidiaries of EU MNEs. The sample consists of large R&D firms that represent about 80% of total European R&D. In general, the results indicate a positive impact from globalization on firms’ R&D productivity, especially in the US, while a negative impact for industrial diversification is found. <p><p>The main question of the fifth chapter is whether the R&D activities that are conducted outside Europe still benefit to European growth. If so, how does the regional location of R&D centers matter in the production process of EU MNEs? The analysis is conducted on the basis of a unique sample of 637 European R&D leaders with information that is consolidated with respect to about 8000 worldwide patenting subsidiaries. The assessment of R&D internationalization is proxied by the regional repartition of the inventors of each firm. The empirical findings suggest that R&D located in Europe yields significant economic results, but a reallocation of R&D located in Europe instead of outside Europe seems to be correlated with lower R&D performances in high-tech sectors, but not in lower-tech industries. Conversely, a larger share of R&D located in the US seems to improve the economic performance of R&D activities within high-tech EU MNEs while the effect is negative for lower-tech companies. Nevertheless, the economic performance of R&D centers in Europe and US is jointly positive and significant for both regions.<p><p>The sixth chapter concludes the dissertation by reviewing the main findings of the previous chapters. Policy implications are summarized and the limitations of the thesis are addressed. Finally, extensions of the scope of the analysis and ideas for future research are suggested. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

Since the introduction of high end graphical workstations, computer animation has quickly replaced the traditional means of animation. Nowadays computer animation has many applications e.g. video games, motion picture industry, media, weather forecasting and many others. This master thesis discusses various techniques used to created animations using computers. Keyframing, is the most common approach in computer animation. Borrowing its name from the concept of traditional hand animation, the workflow process remained the same. Basic principles of animation using key-frames are explained and an Interactive Animation Editor solution based on keyframing is proposed and the implementation of this editor is described. Editor uses the Kochanek-Bartels interpolation of values between each key-frame.
