Open Source strategies have become powerful tools for the development of innovative products in various industries (Von Hippel, 2006). Success stories in computer and clothing manufacturing signify that the adoption of Open Source practices may improve service standards and productivity (Clayton, 2001; Thomle & Von Hippel, 2002). Although Open Source strategies have been adapted in many design industries for satisfying customer demands in customized products, no one has successfully implemented an effective process for integrating Open Source into the building industries (Herbert, 1981, Larson et al., 2004). In an attempt to overcome many of the same barriers to product maturity such ineffective collaboration, lack of data management (Shah, 2003; Rothfuss, 2002), and limitations of product distribution channels, a new participative Open Source platform for transforming building design processes and economics is suggested (Larson et al., 2004). This thesis reexamines the basic assumptions of how building products are distributed through the Open Source environment.
(cont.) By analyzing the impact of e-Business and Internet technology driving community participation, the integration of (1) four online Business models: Dell, Open Source, iTunes, and eBay, and (2) the advent of mass- customization through the revolution of Internet technology, Computer Aided Design (CAD), and Computer Aided Manufacturing (CAM) for architecture and architectural product design and development will be established. The results of this evaluation identify the effective factors for the Internet augmentation framework to achieve the usability of Open Source for the design-build housing industry, and reinforce the changing relationship between homebuyers, architects, and manufacturers prior to making a final housing product.

Effective device management is not trivial due to a variety of devices and software. To keep costs to minimum companies must effectively utilize a unified solution for device management. This research investigated Funambol’s implementation of Open Mobile Alliance Device Management (OMA DM) which is the most popular device management solution. Interviews were used to set experiments and create realistic test cases. A set of devices and a collection of Funambol software were used to create device management sessions. All of the sessions were recorded, analysed, manipulated and resent to identify efficient ways of device management. Additionally, an influence of compression and buffer-like mechanisms were checked. Methods and guidelines are provided for efficient use of OMA DM as well as a reliable analysis of OMA DM Sessions under various conditions. It was found that for most data it is best to use a built-in transport protocol compressor. Hypertext Transfer Protocol’s (HTTP) deflate with a combination of client-side buffering-like mechanism at a client side performed best at most cases. Funambol’s implementation of the Binary Extensible Markup Language (WBXML), in most cases, performed very badly, even though it was designed specifically to compress OMA DM Session messages. It was found that for an efficient use of OMA DM a proper software option set (e.g. forced use of compression) may be sufficient.

Purpose – Since April 2014, the alliance of leading German Institutes of Technology (TU9) has been jointly producing and running massive open online courses (MOOCs) on the subject of engineering. On the one hand, the collaborative MOOC@TU9 project aims to combine the unique characteristics and strengths of the engineering courses offered by the TU9 universities, making inter-institute, cooperative, open learning both visible and accessible. This will enhance both local teaching and the national and international marketing of the universities. On the other hand, the project also aims to help build communal experience and develop quality and production standards for the use of different MOOC formats in digital higher education teaching. In this sense, the MOOC@TU9 project contributes to the vital development of sustainable digitalisation strategies at German universities in the form of a feasibility study, which can then be used in other contexts as a valuable example of best practice. Design/methodology/approach – The MOOC@TU9 project has a primarily practical approach. The focus of the collaboration between the TU9 universities is therefore the discussion, exchange and coordination of concrete actions in addition to the evaluation and assessment of the solutions reached and implemented. The collaboration within the TU9 network results in inter-organisation working and learning processes for the parties and institutions involved. These have a particular value, as this is how, through collaboration, we can build an effective, sustainable, multi-dimensional experience. Originality/value – MOOC@TU9 is a joint inter-university project with the aim of strategically testing the possibilities, parameters and benefits of using massive open online courses in higher education teaching, the like of which has never been seen before in Germany. There is, therefore, currently no systematic development of quality and production standards for MOOCs: a gap, which MOOC@TU9 is actively attempting to fill. Practical implications – Results and findings of the project are not only taken from specific practical work, they are also fed directly back into it. In this respect, it can and should provide valuable insights not only for course participants, but also for other universities and/or initiatives.

Abschließend wird ein Ausblick in die thematische Planung für die nächsten Jahre gegeben.

The importance of search partnerships has grown as a mode to search for innovations. However, in spite of this development, notions of open innovation combined with new propositions to change the search process in favour of sustainability have unravelled a need to take stock of the existing literature of search partnerships and the aims that these partnerships follow. This review addresses this shortcoming and synthesises the literature on search partnerships to analyse the current state of knowledge to deliver future research opportunities. A systematic review process was adopted by means of a set a set of pre-defined stages. These stages included the formulation and positioning of the review question within the larger literature domains, a systematic research process which included the adoption of search strings, relevance and quality appraisal criteria, as well as a stock-taking process of descriptive and thematic features, which followed the logic of prescriptive synthesis. This process led to a representative sample of 73 articles which were analysed subsequently. The tentative findings reveal that the literature is underpinned by a combination of theories linking to evolutionary or transaction-based understandings of search partnerships. Also, six conditions were found to drive search partnerships and when they are likely to form. Moreover five interventions were identified that relate to the use of search methods, boundary spanning activities, and the number, type and involvement levels with the partner. Finally search partnerships have been found to yield five outcomes: partnerships, and various types of innovations, higher social goals, as well as market knowledge. By combining contexts, interventions, and outcomes, research opportunities are identified that should inform future reviews, including the need for more research in sustainability-led search partnership contexts and a better understanding of search strategy configurations in relation interventions used and anticipated search partnership outcomes obtained.

Seit dem Artikel des Geisteswissenschaftlers Roland Reuß „Open Access: Eine heimliche technokratische Machtergreifung“ und dem Heidelberger Appell im März 2009 entstand eine heftige Debatte um Open Access und die Publikationsfreiheit. Der folgende Vortrag gibt eine kurze Einführung in Google Books und das Google Book Settlement, den Reaktionen der VG Wort und dem Aktionsbündnis für „Urheberrecht in Bildung und Wissenschaft“ sowie dem Open-Access-Prinzip. Anhand von Befürworterstimmen des Heidelberger Appells aus der Presse werden die dortigen Kernaussagen „Open Access sei kostenlos“, „Open Access sei von schlechter Qualität“ und „Open Access würde die Autor/innen ihrer Urheberrechte berauben“ diskutiert und die Undifferenziertheit dieser Aussagen aufgezeigt.

The increasing changes in the organizational environment, propelled globalization, have lead companies to rethink their business models in order create value. Therefore, the organizational arrangements that emphasize innovation and cooperation are understood by many researchers as possible answers to these new challenges and potential sources of superior results. This research essay points to different ways of management strategic alliances considering their dynamics, their benefits and risks in environment in which organizational competence of value innovation is of importance. Empirical researches were held at EMBRAER concerning the family regional jets 170/190, as semi-structured interviews, and these data complemented with secondary sources. Bibliographic revision was also done during all the stages of the survey order to assure theoretical basis and offer main subsidies to the questionary preparation, the choice of methodology and the field data collection work itself. The results of the empirical data point to, among others, some relevant contributions: the importance of strategic alliances in an open innovation model, the possibility that innovation might be considered an organizational competence and the importance of value innovation to create new markets in which traditional competition becomes secondary importance

Consumers of digital contents are empowered with numerous technologies allowing them to produce perfect copies of these contents and distribute them around the world with little or no cost. To prevent illegal copying and distribution, a technology called Digital Rights Management (DRM) is developed. With this technology, consumers are allowed to access digital contents only if they have purchased the corresponding licenses from license issuers. The problem, however, is that those consumers are not allowed to resell their own licenses- a restriction that goes against the first-sale doctrine. Enabling a consumer to buy a digital license directly from another consumer and allowing the two consumers to fairly exchange the license for a payment are still an open issue in DRM research area. This thesis investigates existing security solutions for achieving digital license reselling and analyses their strengths and weaknesses. The thesis then proposes a novel Reselling Deal Signing (RDS) protocol to achieve fairness in a license reselling. The idea of the protocol is to integrate the features of the concurrent signature scheme with functionalities of a License Issuer (LI). The security properties of this protocol is informally analysed and then formally verified using ATL logic and the model checker MOCHA. To assess its performance, a prototype of the RDS protocol has been developed and a comparison with related protocols has been conducted. The thesis also introduces two novel digital tokens a Reselling Permission (RP) token and a Multiple Reselling Permission (MRP) token. The RP and MRP tokens are used to show whether a given license is single and multiple resalable, respectively. Moreover, the thesis proposes two novel methods supporting fair and secure digital license reselling. The first method is the Reselling Deal (RD) method which allows a license to be resold once. This method makes use of the existing distribution infrastructure, RP, License Revocation List (LRL), and three protocols: RDS protocol RD Activation (RDA) protocol, and RD Completion (RDC) protocol. The second method is a Multiple License Reselling (MLR) method enabling one license to be resold N times by N consumers. The thesis presents two variants of the MLR method: RRP-MR (Repeated RP-based Multi-Reselling) and HC-MR (Hash Chain-based Multi-Reselling). The RRP-MR method is designed such that a buyer can choose to either continue or stop a multi-reselling of a license. Like the RD method, the RRP-MR method makes use of RP, LI, LRL, and the RDS, RDA, and RDC protocols to achieve fair and secure reselling. The HC-MR method allows multiple resellings while keeping the overhead on LI at a minimum level and enable a buyer to check how many times a license can be further resold. To do so, the HC-MR utilises MRP and the hash chain cryptographic primitive along with LRL, LI and the RDS, RDA and RDC protocols. The analysis and the evaluation of these three methods have been conducted. While supporting the license reselling, the two methods are designed to prevent a reseller from (1) continuing using a resold license, (2) reselling a non-resalable license, and (3) reselling one license a unauthorised number of times. In addition, they enable content owners of resold contents to trace a buyer who has violated any of the usage rights of a license bought from a reseller. Moreover, the methods enable a buyer to verify whether a license he is about to buy is legitimate for re-sale. Furthermore, the two methods support market power where a reseller can maximise his profit and a buyer can minimise his cost in a reselling process. In comparison with related works, our solution does not make use of any trusted hardware device, thus it is more cost-effective, while satisfying the interests of both resellers and buyers, and protecting the content owner's rights.

Nowadays society strongly depends on its available resources and the long term stability of the surrounding ecosystem. Numerical modelling has become a general standard for evaluating past, current or future system states for a large number of applications supporting decision makers in proper management. In order to ensure the correct representation of the investigated processes and results of a simulation, verification examples (benchmarks), that are based on observation data or analytical solutions, are utilized to evaluate the numerical modelling tool. In many parts of the world, groundwater is an important resource for freshwater. While it is not only limited in quantity, subsurface water bodies are often in danger of contamination from various natural or anthropogenic sources. Especially in arid regions, marine saltwater intrusion poses a major threat to groundwater aquifers which mostly are the exclusive source of freshwater in these dry climates. In contrast to common numerical groundwater modelling, density-driven flow and mass transport have to be considered as vital processes in the system and in scenario simulations for fresh-saltwater interactions. In the beginning of this thesis, the capabilities of the modelling tool OpenGeoSys are verified with selected benchmarks to represent the relevant non-linear process coupling. Afterwards, variable-density application and process studies on different scales are presented. Application studies comprehend regional groundwater modelling of a coastal aquifer system extensively used for agricultural irrigation, as well as hydro-geological model development and parametrization. In two process studies, firstly, a novel method to model gelation of a solute in porous media is developed and verified on small scale laboratory observation data, and secondly, investigations of thermohaline double-diffusive Rayleigh regimes on medium scale are carried out. With the growing world population and, thus, increasing pressure on non-renewable resources, intelligent management strategies intensify demand for potent simulation tools and development of novel methods. In that way, this thesis highlights not only OpenGeoSys’ potential of density-dependent process modelling, but the comprehensive importance of variable-density flow and transport processes connecting, both, avant-garde scientific research, and real-world application challenges.

En centrales nucléaires, un accident grave est une séquence très peu probable d’événements durant laquelle des composants du réacteur sont significativement endommagés, par interactions chimiques et/ou fusion, à cause de très hautes températures. Cela peut mener à des rejets radiotoxiques dans l’enceinte et à une entrée d’air dans le réacteur. Dans ce contexte, ce travail de thèse mené chez EDF R&D visait à modéliser la détérioration du gainage combustible, en alliages de zirconium, en conditions accidentelles : haute température et soit vapeur soit mélange air-vapeur. L’objectif final était d’améliorer la simulation par le code MAAP de l’oxydation du gainage et de la production d’hydrogène, en particulier pendant un renoyage avec de l’eau. Dû à l’épaississement progressif d’une couche de ZrO2 dense et protectrice, la cinétique d’oxydation du Zr en vapeur à hautes températures est généralement (sous-)parabolique. Cependant, à certaines températures, cette couche d’oxyde peut se fissurer, devenant poreuse et non protectrice. Par ce processus de « breakaway », la cinétique d’oxydation devient plus linéaire. De plus, l’augmentation de température peut mener les matériaux du réacteur à fondre et à se relocaliser dans le fond de cuve dont la rupture peut induire une entrée d’air dans le réacteur. Dans ce cas, l’oxygène et l’azote réagissent avec les gaines pré-oxydées, successivement par oxydation du Zr (épaississant la couche de ZrO2), nitruration du Zr (formant des particules de ZrN) et oxydation du ZrN (créant de l’oxyde et relâchant de l’azote). Ces réactions auto-entretenues relancent la fissuration du gainage et de sa couche de ZrO2, induisant une hausse de sa porosité ouverte. Afin de quantifier cette porosité du gainage, un protocole expérimental innovant en deux étapes a été défini et appliqué : il consistait à soumettre des échantillons de gainage en ZIRLO® à diverses conditions accidentelles pendant plusieurs durées puis à des mesures de la porosité ouverte par porosimétrie par intrusion de mercure. Les conditions de corrosion comprenaient plusieurs températures allant de 1100 à 1500 K ainsi que de la vapeur et un mélange air-vapeur 50-50 mol%. Pour les échantillons de ZIRLO® oxydés en vapeur, sauf à 1200 et 1250 K, les transitions de cinétique n’ont pas lieu et la porosité ouverte reste négligeable au cours de l’oxydation. Cependant, pour les autres échantillons, corrodés en air-vapeur ou oxydés en vapeur à 1200 ou 1250 K, des transitions « breakaway » sont observées et les résultats de porosimétrie montrent que la porosité ouverte augmente au cours de la corrosion, proportionnellement au gain en masse. De plus, il a été mis en évidence que la distribution de tailles de pores des échantillons de ZIRLO® s’étend significativement pendant la corrosion, en particulier après « breakaway ». En effet, ces tailles vont de 60 μm à environ : 2 μm avant la transition, 50 nm juste après et 2 nm plus longtemps après. Enfin, un modèle numérique en deux étapes a été développé dans le code MAAP pour améliorer sa simulation de l’oxydation du gainage. D’abord, grâce à la proportionnalité entre porosité ouverte et gain en masse des échantillons, des corrélations de porosité ont été implémentées pour chaque condition de corrosion. Ensuite, les valeurs de porosité calculées sont utilisées pour augmenter proportionnellement la vitesse d’oxydation du gainage. Ce modèle amélioré simule ainsi non seulement les réactions chimiques des gaines en Zr (oxydation et nitruration) mais aussi leur dégradation mécanique et son impact sur leur vitesse d’oxydation. Ceci a été validé en simulant des essais QUENCH (-06, -08, -10 et -16), conduits au KIT pour étudier le comportement de gaines dans des conditions accidentelles avec un renoyage final. Ces simulations montrent un meilleur comportement thermique du gainage et une production d’hydrogène significativement plus haute et donc plus proche des valeurs expérimentales, en particulier pendant le renoyage
In nuclear power plants, a severe accident is a very unlikely sequence of events during which components of the reactor core get significantly damaged, through chemical interactions and/or melting, because of very high temperatures. This may potentially lead to radiotoxic releases in the containment building and to air ingress in the reactor core. In that context, this thesis work led at EDF R&D aimed at modeling the deterioration of the nuclear fuel cladding, made of zirconium alloys, in accidental conditions: high temperature and either pure steam or air-steam mixture. The final objective was to improve the simulation by the MAAP code of the cladding oxidation and of the hydrogen production, in particular during a core reflooding with water. Due to the progressive thickening of a dense and protective ZrO2 layer, the oxidation kinetics of Zr in steam at high temperatures is generally (sub-)parabolic. However, at certain temperatures, this oxide layer may crack, becoming porous and not protective anymore. By this “breakaway” process, the oxidation kinetics becomes rather linear. Additionally, the temperature increase can lead core materials to melt and to relocate down to the vessel lower head whose failure may induce air ingress into the reactor core. In this event, oxygen and nitrogen both react with the pre-oxidized claddings, successively through oxidation of Zr (thickening the ZrO2 layer), nitriding of Zr (forming ZrN particles) and oxidation of ZrN (creating oxide and releasing nitrogen). These self-sustained reactions enhance the cracking of the cladding and of its ZrO2 layer, inducing a rise of its open porosity.In order to quantify this cladding porosity, an innovative two-step experimental protocol was defined and applied: it consisted in submitting ZIRLO® cladding samples first to various accidental conditions during several time periods and then to measurements of the open porosity through porosimetry by mercury intrusion. The tested corrosion conditions included numerous temperatures ranging from 1100 up to 1500 K as well as both pure steam and a 50-50 mol% air-steam mixture. For the ZIRLO® samples oxidized in pure steam, except at 1200 and 1250 K, the “breakaway” kinetic transitions do not occur and the open porosity remains negligible along the oxidation process. However, for all other samples, corroded in air-steam or oxidized in pure steam at 1200 or 1250 K, “breakaway” transitions are observed and the porosimetry results show that the open porosity increases along the corrosion process, proportionally to the mass gain. Moreover, it was evidenced that the pore size distribution of ZIRLO® samples significantly extends during corrosion, especially after “breakaway” transitions. Indeed, the detected pore sizes ranged from 60 μm down to around: 2 μm before the transition, 50 nm just after and 2 nm longer after. Finally, a two-step numerical model was developed in the MAAP code to improve its simulation of the cladding oxidation. First, thanks to the proportionality between open porosity and mass gain of cladding samples, porosity correlations were implemented for each tested corrosion condition. Second, the calculated porosity values are used to proportionally enhance the cladding oxidation rate. This improved model thus simulates not only chemical reactions of Zr-based claddings (oxidation and nitriding) but also their mechanical degradation and its impact on their oxidation rate. It was validated by simulating QUENCH tests (-06, -08, -10 and -16), conducted at KIT to study the behavior of claddings in accidental conditions with a final reflooding. These simulations show a better cladding thermal behavior and a hydrogen production significantly higher and so closer to experimental values, in particular during the reflooding

Isolation is not the way that a firm can innovate; they need the networks of suppliers, customers, competitors and more broadly, cooperation with other partners in the value chain. Costly R&D innovation and Intellectual Property Rights further enhances the trends to setup strategic alliance to utilize other firms’ strengths. (Chesbrough, H., 2003). Currently, while high technological industries are the bones of Taiwan economy but they are facing unforeseeable instabilities, new key industry would be required to quickly bring Taiwan to its second “miracle”. This paper suggests the application of open innovation and strategic alliances between biotech startups and international corporations to boost Taiwan drug discovery and drug development processes to flourish. More importantly, BioICT, the combination of Taiwan emerging Biotechnology industry and Information Communication Technology, which has been for long Taiwan’s competitive advantages is expected to help the island excel and become leading player in the field.

Many enterprises encounter unprecedented impact and intense competition due to the rising of globalization and internationalization. Furthermore, Taiwan faced with the rise of mainland China, the traditional way to fight in the industrial market, to develop and to manufacture by stand alone is no more suitable for the modern competed industrial market. Therefore, the integrated steel mill - China Steel Corporation speeds up in innovation and R&D area , to come out to reach the client from inside of CSC and to form the technical strategy alliances with both upstream and downstream of steel industry. The benefits for such strategy alliances are to gain more strength, to have the more high-value products and to have the differential improvement. Therefore, the issues about the influcing factors and performance of China Steel Corporation intergrated both upstream and downstream strategic alliance are worthy of further discussion The study was proceeded by the research and development of strategic alliances, refer to the study of many scholars in the past discussed on the Transaction Cost Theory, Resource Dependence Theory, value appropriation of R&D, and open innovation. The results showed that: "Information sufficient", "trust", "bargaining chips", and "scarce resources" have a significant positive impact on the value appropriation of R&D. "Open innovation" has negative moderating effect between "information sufficient", "trust", "scarce resources", and " value appropriation of R&D ". "Open innovation" does not have the effect between "bargaining chips" and " value appropriation of R&D ".

The evolving of the networking application and electronic components are pushing the bandwidth limits in the automotive domain [19]. Consequently, the car manufacturers have begun to produce more complex Electronic Control Units (ECUs) to fulfil the automotive technology evolution. Car manufacturers have used ECUs from different vendors to get the most creative features in cars [19]. These ECUs requires a standard network interface such as Ethernet which can bring significant features such as high bandwidth, low weight and full duplex communication. Nowadays, Ethernet has adapted to apply in the automotive application. Therefore, it has called for a high degree of testing to ensure the safety and interoperability between these ECUs. However, the testing of the Automotive Ethernet is facing many challenges such as finding and solving the issues as early as possible in the development process. Besides that, testing an Automotive Ethernet TCP/IP stack is a complex task, as it required an upper tester to cause the implementation of the device under the test to move to specific states. AUTOSAR has defined a standardised control protocol (Test Stub) to use it as an upper tester for executing the AUTOSAR Acceptance Test (for TCP/IP stack) [6]. This protocol has used for conducting the test cases of the TCP, UDP and IP protocols in AUTOSAR [21] [22] [23]. OPEN Alliance has specified an Automotive Ethernet ECU test specification which covers more protocols than AUTOSAR such as ARP and DHCP [7]. Consequently, potential gaps and issues may arise when using the Test Stub to conduct the test cases of the OPEN Alliance, as it initially defined for conducting the AUTOSAR Acceptance Test. This work presents the evaluation of the Test Stub in context of using it to conduct the OPEN Alliance Automotive Ethernet ECU Test. Furthermore, it will introduce a solution to overcome the potential issues and gaps which may arise after using the Test Stub (defined by AUTOSAR) to conduct the test cases of the OPEN Alliance.

This dissertation makes an attempt to scientifically investigate Erich Sauer's theology of salvation history for the first time. Sauer grew up in a vital missionary context in the setting of the Open Brethren fellowship and the Alliance Bible School in Berlin. He studied history, philology and theology at the Humboldt University in Berlin, with the goal of promoting missions. Because of an acute eye ailment he was forced to discontinue his studies. He was invited to Wiedenest, where he found his life's work in the Bible School, which had moved in 1919. Here he worked for almost forty years as a teacher and a writer and travelling unceasingly to preach, lecture and hold biblical seminars on the topic of salvation history and missions. His theology, which is indebted to the theory of revelation history, was influenced by federal theology, theology of salvation history and the scientific, exegetic theology of German theological positivism. Sauer derives the authority of Scripture from history and develops a complex, salvation historical model, which is characterised by the classic structure of protology, soteriology and eschatology. His pre-millennial character is not dispensationally restricted, but has, rather, its own independent formation, that allows for the universal dimensions of God's completion act, without supporting a universal redemption theory. Through the high rating that he gives the position of the ecclesia in salvation history, Sauer has achieved a programmatic missions concept, which sees a missions-oriented church within every local church. With this paradigmatic theory, Sauer contributed to a revival of missions in German Brethren congregations, in conjunction with his professional colleague Schrupp.
