emerging technologies, changes in existing technologies, as well as relevant related changes in the market's structures and participants. Therefore, many companies conduct technology intelligence (TI) activities to ensure an early identification of appropriate technologies and other (weak) signals. One base activity of TI is technology monitoring, which is defined as the systematic tracking of developments within a specified topic of interest as well as related trends over a long period of time. Due to the very large number of dynamically changing parameters within the technological and the market environment of a company as well as their possible interdependencies, it is necessary to focus technology monitoring on specific indicators or other criteria, which are able to point out technological developments and market changes. In addition to the execution of a literature review on existing approaches, which mainly propose patent-based indicators, it is examined in this paper whether indicator systems from other branches such as risk management or economic research could be transferred to technology monitoring in order to enable an efficient and focused technology monitoring for companies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technology%20forecasting" title="technology forecasting">technology forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20indicator" title=" technology indicator"> technology indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20intelligence" title=" technology intelligence"> technology intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20management" title=" technology management"> technology management</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20monitoring" title=" technology monitoring"> technology monitoring</a> </p> <a href="https://publications.waset.org/abstracts/34402/focusing-of-technology-monitoring-activities-using-indicators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34402.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">470</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> "Epitaph" Charles Mingus’ Foresight of Jazz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christel%20Elisabeth%20Bonin">Christel Elisabeth Bonin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The score of the 2 ½ hour ‘magnum opus’ named ‘Epitaph’ was reconstructed 10 years after Charles Mingus’ death in 1979. Most of the movements were probably composed in the late 1950s. As the finale was missing, Gunther Schuller, the conductor of the world premiere in 1989, decided to improvise one with the orchestra, using Mingus as a guide. The aim of this paper is to analyze ‘Main Score Part I ‘ and ‘Main Score Part II’ and to look into the score of Mingus’ reconstructed compositions under particular observation of the new finale, ‘Main Score Reprise’. There, Mingus left instructions for a return to the opening section of ‘Epitaph’. By examining ‘Epitaph’ in the historical context of Jazz between 1955 to 1967 and the 1980s and comparing the finale of ‘Epitaph’, created - or better said: improvised - by the musicians of the 1989 world premiere with the opening section, at first it will be interesting to discover at which point Gunther Schuller followed Mingus creative process and brought it to life in 1989. Finally, it will be speculated if Charles Mingus composition still represents a foresight of Jazz nearly 30 years after its creation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epitaph" title="epitaph">epitaph</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Mingus" title=" Charles Mingus"> Charles Mingus</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunter%20Schuller" title=" Gunter Schuller"> Gunter Schuller</a>, <a href="https://publications.waset.org/abstracts/search?q=jazz%20reception" title=" jazz reception"> jazz reception</a>, <a href="https://publications.waset.org/abstracts/search?q=bebop" title=" bebop"> bebop</a>, <a href="https://publications.waset.org/abstracts/search?q=hardbop" title=" hardbop"> hardbop</a>, <a href="https://publications.waset.org/abstracts/search?q=Duke%20Ellington" title=" Duke Ellington"> Duke Ellington</a>, <a href="https://publications.waset.org/abstracts/search?q=black" title=" black"> black</a>, <a href="https://publications.waset.org/abstracts/search?q=brown%20and%20beige" title=" brown and beige"> brown and beige</a>, <a href="https://publications.waset.org/abstracts/search?q=African-American%20music" title=" African-American music"> African-American music</a>, <a href="https://publications.waset.org/abstracts/search?q=free-jazz" title=" free-jazz"> free-jazz</a> </p> <a href="https://publications.waset.org/abstracts/41947/epitaph-charles-mingus-foresight-of-jazz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41947.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> On the Combination of Patient-Generated Data with Data from a Secure Clinical Network Environment: A Practical Example</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeroen%20S.%20de%20Bruin">Jeroen S. de Bruin</a>, <a href="https://publications.waset.org/abstracts/search?q=Karin%20Schindler"> Karin Schindler</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Schuh"> Christian Schuh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With increasingly more mobile health applications appearing due to the popularity of smartphones, the possibility arises that these data can be used to improve the medical diagnostic process, as well as the overall quality of healthcare, while at the same time lowering costs.

Until now, conventional evaluation methods primarily consider the costs of manufacturing technologies. Thus, the potential of manufacturing technologies for achieving additional product design features is not completely captured. To compensate this deficit, final evaluations of new technologies are mainly intuitive in practice. Therefore, an additional evaluation dimension is needed which takes the potential of manufacturing technologies for specific realizable product designs into account. In this paper, we present the approach of an evaluation method for selecting manufacturing technologies with regard to their potential for product designing. This research is done within the Fraunhofer innovation cluster »AdaM« (Adaptive Manufacturing) which targets the development of resource efficient and adaptive manufacturing technology processes for complex turbo machinery components. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title="manufacturing">manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20design" title=" product design"> product design</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20assessment" title=" technology assessment"> technology assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20management" title=" technology management"> technology management</a> </p> <a href="https://publications.waset.org/abstracts/16517/approach-for-an-integrative-technology-assessment-method-combining-product-design-and-manufacturing-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16517.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">534</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Governance of Inter-Organizational Research Cooperation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guenther%20Schuh">Guenther Schuh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Woelk"> Sebastian Woelk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Companies face increasing challenges in research due to higher costs and risks. The intensifying technology complexity and interdisciplinarity require unique know-how. Therefore, companies need to decide whether research shall be conducted internally or externally with partners. On the other hand, research institutes meet increasing efforts to achieve good financing and to maintain high research reputation. Therefore, relevant research topics need to be identified and specialization of competency is necessary. However, additional competences for solving interdisciplinary research projects are also often required. Secured financing can be achieved by bonding industry partners as well as public fundings. The realization of faster and better research drives companies and research institutes to cooperate in organized research networks, which are managed by an administrative organization. For an effective and efficient cooperation, necessary processes, roles, tools and a set of rules need to be determined. The goal of this paper is to show the state-of-art research and to propose a governance framework for organized research networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interorganizational%20cooperation" title="interorganizational cooperation">interorganizational cooperation</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20network%20governance" title=" design of network governance"> design of network governance</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20network" title=" research network"> research network</a> </p> <a href="https://publications.waset.org/abstracts/34395/governance-of-inter-organizational-research-cooperation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34395.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> The Awareness of Computer Science Students Regarding the Security of Location Based Games</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jacques%20Barnard">Jacques Barnard</a>, <a href="https://publications.waset.org/abstracts/search?q=Magda%20Huisman"> Magda Huisman</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20R.%20Drevin"> Gunther R.

As a consequence of this fast expanding market and new technology, it is important to be aware of the implications this has on security. This paper measures the impact on the security awareness of games’ participants, as well as on that of students at university level with regards to their various stages of input in years of studying and gamer classification. This serves to provide insight into the matter as to discernible differences in the awareness of the security implications concerning these technologies. The data was accumulated via a web questionnaire that was to be completed yearly by students from respective year groups. Results signify a meaningful disparity in security awareness among students completing the varying study years and research. This awareness, however, does not always impact on gamers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gamer%20classifications" title="gamer classifications">gamer classifications</a>, <a href="https://publications.waset.org/abstracts/search?q=location%20based%20games" title=" location based games"> location based games</a>, <a href="https://publications.waset.org/abstracts/search?q=location%20based%20data" title=" location based data"> location based data</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20awareness" title=" security awareness"> security awareness</a> </p> <a href="https://publications.waset.org/abstracts/1969/the-awareness-of-computer-science-students-regarding-the-security-of-location-based-games" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1969.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Modeling and Control Design of a Centralized Adaptive Cruise Control System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Markus%20Mazzola">Markus Mazzola</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20Schaaf"> Gunther Schaaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A vehicle driving with an Adaptive Cruise Control System (ACC) is usually controlled decentrally, based on the information of radar systems and in some publications based on C2X-Communication (CACC) to guarantee stable platoons. In this paper, we present a Model Predictive Control (MPC) design of a centralized, server-based ACC-System, whereby the vehicular platoon is modeled and controlled as a whole. It is then proven that the proposed MPC design guarantees asymptotic stability and hence string stability of the platoon. The Networked MPC design is chosen to be able to integrate system constraints optimally as well as to reduce the effects of communication delay and packet loss. The performance of the proposed controller is then simulated and analyzed in an LTE communication scenario using the LTE/EPC Network Simulator LENA, which is based on the ns-3 network simulator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20cruise%20control" title="adaptive cruise control">adaptive cruise control</a>, <a href="https://publications.waset.org/abstracts/search?q=centralized%20server" title=" centralized server"> centralized server</a>, <a href="https://publications.waset.org/abstracts/search?q=networked%0D%0Amodel%20predictive%20control" title=" networked model predictive control"> networked model predictive control</a>, <a href="https://publications.waset.org/abstracts/search?q=string%20stability" title=" string stability"> string stability</a> </p> <a href="https://publications.waset.org/abstracts/6450/modeling-and-control-design-of-a-centralized-adaptive-cruise-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">514</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Competitive Advantage: Sustainable or Transient</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pallavi%20Thacker">Pallavi Thacker</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20P.%20Mathur"> H.

It has been stated a number of times that firms must strive to attain sustainable competitive advantage; but is the concept of sustainability of advantage still valid in this new diversified and too-rapidly changing world? The paper reaches a conclusion that the answer is “no”. Gone is the time when once attained position could easily be retained forever or at-least for a substantial amount of time. We live in a time which is very much globalised. We are used to a high level of competition from all directions. Technological advances, developed human capital, flexibility and end number of factors make the sustenance of competitive advantage difficult. This paper analyses competitive advantage from the view points of Michael Porter (who talks about sustainability) and Rita Gunther McGrath (who says competitive advantage can no more be sustained). It uses many examples and evidences from papers, journals and news. A research in this area is very much required (especially in a developing country like India) so that industries, firms and people can find out the suitable strategies that match with the changing times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=competitive%20advantage" title="competitive advantage">competitive advantage</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=transient" title=" transient"> transient</a>, <a href="https://publications.waset.org/abstracts/search?q=globalisation" title=" globalisation"> globalisation</a> </p> <a href="https://publications.waset.org/abstracts/37385/competitive-advantage-sustainable-or-transient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37385.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Concept for Determining the Focus of Technology Monitoring Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guenther%20Schuh">Guenther Schuh</a>, <a href="https://publications.waset.org/abstracts/search?q=Christina%20Koenig"> Christina Koenig</a>, <a href="https://publications.waset.org/abstracts/search?q=Nico%20Schoen"> Nico Schoen</a>, <a href="https://publications.waset.org/abstracts/search?q=Markus%20Wellensiek"> Markus Wellensiek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Identification and selection of appropriate product and manufacturing technologies are key factors for competitiveness and market success of technology-based companies. Therefore many companies perform technology intelligence (TI) activities to ensure the identification of evolving technologies at the right time. Technology monitoring is one of the three base activities of TI, besides scanning and scouting. As the technological progress is accelerating, more and more technologies are being developed. Against the background of limited resources it is therefore necessary to focus TI activities. In this paper, we propose a concept for defining appropriate search fields for technology monitoring. This limitation of search space leads to more concentrated monitoring activities. The concept will be introduced and demonstrated through an anonymized case study conducted within an industry project at the Fraunhofer Institute for Production Technology. The described concept provides a customized monitoring approach, which is suitable for use in technology-oriented companies especially those that have not yet defined an explicit technology strategy. It is shown in this paper that the definition of search fields and search tasks are suitable methods to define topics of interest and thus to direct monitoring activities. Current as well as planned product, production and material technologies as well as existing skills, capabilities and resources form the basis of the described derivation of relevant search areas. To further improve the concept of technology monitoring the proposed concept should be extended during future research e.g. by the definition of relevant monitoring parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monitoring%20radar" title="monitoring radar">monitoring radar</a>, <a href="https://publications.waset.org/abstracts/search?q=search%20field" title=" search field"> search field</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20intelligence" title=" technology intelligence"> technology intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20monitoring" title=" technology monitoring"> technology monitoring</a> </p> <a href="https://publications.waset.org/abstracts/16554/concept-for-determining-the-focus-of-technology-monitoring-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16554.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">474</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Assembly Training: An Augmented Reality Approach Using Design Science Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Werrlich">Stefan Werrlich</a>, <a href="https://publications.waset.org/abstracts/search?q=Phuc-Anh%20Nguyen"> Phuc-Anh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai%20Nitsche"> Kai Nitsche</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20Notni"> Gunther Notni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Augmented Reality (AR) is a strong growing research topic. This innovative technology is interesting for several training domains like education, medicine, military, sports and industrial use cases like assembly and maintenance tasks. AR can help to improve the efficiency, quality and transfer of training tasks. Due to these reasons, AR becomes more interesting for big companies and researchers because the industrial domain is still an unexplored field. This paper presents the research proposal of a PhD thesis which is done in cooperation with the BMW Group, aiming to explore head-mounted display (HMD) based training in industrial environments. We give a short introduction, describing the motivation, the underlying problems as well as the five formulated research questions we want to clarify along this thesis. We give a brief overview of the current assembly training in industrial environments and present some AR-based training approaches, including their research deficits. We use the Design Science Research (DSR) framework for this thesis and describe how we want to realize the seven guidelines, mandatory from the DSR. Furthermore, we describe each methodology which we use within that framework and present our approach in a comprehensive figure, representing the entire thesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly" title="assembly">assembly</a>, <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title=" augmented reality"> augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20proposal" title=" research proposal"> research proposal</a>, <a href="https://publications.waset.org/abstracts/search?q=training" title=" training"> training</a> </p> <a href="https://publications.waset.org/abstracts/72645/assembly-training-an-augmented-reality-approach-using-design-science-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72645.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Digital Privacy Legislation Awareness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Henry%20Foulds">Henry Foulds</a>, <a href="https://publications.waset.org/abstracts/search?q=Magda%20Huisman"> Magda Huisman</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20R.%20Drevin"> Gunther R.

However, in supply chains of IoT-connected enterprises, the ERP (Enterprise-Resource-Planning), the MES (Manufacturing-Execution-System) and the SCADA (Supervisory-Control-and-Data-Acquisition) systems generate large amounts of data, which generally glean much earlier notice of deviations in the business process steps. That is, analyzing these streams of data with process mining techniques allows the monitoring of the supply chain business processes and thus identification of items that deviate from the standard order fulfillment process. In this paper, a framework to enable event-based SCM (Supply-Chain-Management) processes including an overview of core enabling technologies are presented, which is based on the RAMI (Reference-Architecture-Model for Industrie 4.0) architecture. The application of this framework in the industry is presented, and implications for SCM in industry 4.0 and further research are outlined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyber-physical%20production%20systems" title="cyber-physical production systems">cyber-physical production systems</a>, <a href="https://publications.waset.org/abstracts/search?q=event-based%20monitoring" title=" event-based monitoring"> event-based monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a>, <a href="https://publications.waset.org/abstracts/search?q=RAMI%20%28Reference-Architecture-Model%20for%20Industrie%204.0%29" title=" RAMI (Reference-Architecture-Model for Industrie 4.0)"> RAMI (Reference-Architecture-Model for Industrie 4.0)</a> </p> <a href="https://publications.waset.org/abstracts/75155/a-framework-for-event-based-monitoring-of-business-processes-in-the-supply-chain-management-of-industry-40" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75155.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">236</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Simulative Study of the Influence of Degraded Twin-Tube Shock Absorbers on the Lateral Forces of Vehicle Axles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Schramm">Tobias Schramm</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCnther%20Prokop"> Günther Prokop</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Degraded vehicle shock absorbers represent a risk for road safety. The exact effect of degraded vehicle dampers on road safety is still the subject of research. This work is intended to contribute to estimating the effect of degraded twin-tube dampers of passenger cars on road safety. An axle model was built using a damper model to simulate different degradation levels. To parameterize the model, a realistic parameter space was estimated based on test rig measurements and database analyses, which is intended to represent the vehicle field in Germany. Within the parameter space, simulations of the axle model were carried out, which calculated the transmittable lateral forces of the various axle configurations as a function of vehicle speed, road surface, damper conditions and axle parameters. A degraded damper has the greatest effect on the transmittable lateral forces at high speeds and in poor road conditions. If a vehicle is traveling at a speed of 100 kph on a Class D road, a degraded damper reduces the transmissible lateral forces of an axle by 20 % on average. For individual parameter configurations, this value can rise to 50 %. The axle parameters that most influence the effect of a degraded damper are the vertical stiffness of the tire, the unsprung mass and the stabilizer stiffness of the axle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicle%20dynamics" title="vehicle dynamics">vehicle dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20simulation" title=" vehicle simulation"> vehicle simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20component%20degradation" title=" vehicle component degradation"> vehicle component degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20absorber%20model" title=" shock absorber model"> shock absorber model</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20absorber%20degradation" title=" shock absorber degradation"> shock absorber degradation</a> </p> <a href="https://publications.waset.org/abstracts/154108/simulative-study-of-the-influence-of-degraded-twin-tube-shock-absorbers-on-the-lateral-forces-of-vehicle-axles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Aspects of the Reproductive Biology of the Reticulate Knife Fish, Papyrocranus afer (Gunther, 1868) In Lekki Lagoon, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adiaha%20A.%20A.%20Ugwumba">Adiaha A.

A Total of 1154 specimens with standard lengths of 5.2-75.9 cm (mean = 34.86±17.2cm) and body weight of 7.9-1, 958.8g (mean = 249.12±28.56g) were collected by means of artisanal passive and active gears (traps, long lines, and nets) and examined. Sexes of fish specimens were determined macroscopically and microscopically after dissection. The length at which 50% of the fish population reached sexual maturity (Lₘ₅₀) was considered as length at sexual maturity. Fecundity was determined by total counts of eggs; sex ratio by the proportion of males to females, while GSI was determined as gonad weight expressed as a percentage of total body weight. Results showed that the most frequently caught fish was 34.5cm long, while the sizes at maturity were 49.1cm (males) and 53.4cm (females). Matured specimens had characteristic urinogenital papillae prominent in males but vestigial in females. Sex ratio (1: 0.6; Male: female) was significantly different (X² (1) = 32.21, p < 0.0001). Fecundity was low (mean 49 ± 17 eggs for a fish of 52.86 ±7.53cm); it increased with fish size (r = 0.71). Higher GSI during the rainy season with a peak in July (female: 0.44 ± 0.14 %; male: 0.22 ± 0.01 %) indicated seasonal/annual spawning. Low fecundity and annual spawning underlined the need for sustainable management of this species in Lekki Lagoon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breeding%20season" title="breeding season">breeding season</a>, <a href="https://publications.waset.org/abstracts/search?q=fecundity" title=" fecundity"> fecundity</a>, <a href="https://publications.waset.org/abstracts/search?q=gonad%20maturity" title=" gonad maturity"> gonad maturity</a>, <a href="https://publications.waset.org/abstracts/search?q=Lekki%20lagoon" title=" Lekki lagoon"> Lekki lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Papyrocranus%20afer" title=" Papyrocranus afer"> Papyrocranus afer</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20ratio" title=" sex ratio"> sex ratio</a> </p> <a href="https://publications.waset.org/abstracts/160640/aspects-of-the-reproductive-biology-of-the-reticulate-knife-fish-papyrocranus-afer-gunther-1868-in-lekki-lagoon-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160640.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">69</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Demand-Oriented Supplier Integration in Agile New Product Development Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guenther%20Schuh">Guenther Schuh</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Schroeder"> Stephan Schroeder</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Faulhaber"> Marcel Faulhaber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Companies are facing an increasing pressure to innovate faster, cheaper and more radical in last years, due to shrinking product lifecycles and higher volatility of markets and customer demands. Especially established companies struggle meeting those demands. Thus, many producing companies are adapting their development processes to address this increasing pressure. One approach taken by many companies is the use of agile, highly iterative development processes to reduce development times and costs as well as to increase the fulfilled customer requirements and the realized level of innovation. At the same time decreasing depths of added value and increasing focus on core competencies as well as a growing product complexity result in a high dependency on suppliers and external development partners during the product development. Thus, a successful introduction of agile development methods into the development of physical products requires also a successful integration of the necessary external partners and suppliers into the new processes and procedures and an adaption of the organizational interfaces to external partners according to the new circumstances and requirements of agile development processes. For an effective and efficient product development, the design of customer-supplier-relationships should be demand-oriented. A significant influence on the required design has the characteristics of the procurement object. Examples therefore are the complexity of technical interfaces between supply object and final product or the importance of the supplied component for the major product functionalities. Thus, this paper presents an approach to derive general requirements on the design of supplier integration according to the characteristics of supply objects. First, therefore the most relevant evaluation criteria and characteristics have been identified based on a thorough literature review. Subsequently the resulting requirements on the design of the supplier integration were derived depending on the different possible values of these criteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iterative%20development%20processes" title="iterative development processes">iterative development processes</a>, <a href="https://publications.waset.org/abstracts/search?q=agile%20new%20product%20development" title=" agile new product development"> agile new product development</a>, <a href="https://publications.waset.org/abstracts/search?q=procurement" title=" procurement"> procurement</a>, <a href="https://publications.waset.org/abstracts/search?q=supplier%20integration" title=" supplier integration"> supplier integration</a> </p> <a href="https://publications.waset.org/abstracts/94123/demand-oriented-supplier-integration-in-agile-new-product-development-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94123.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Identification of Vehicle Dynamic Parameters by Using Optimized Exciting Trajectory on 3- DOF Parallel Manipulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Di%20Yao">Di Yao</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20Prokop"> Gunther Prokop</a>, <a href="https://publications.waset.org/abstracts/search?q=Kay%20Buttner"> Kay Buttner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dynamic parameters, including the center of gravity, mass and inertia moments of vehicle, play an essential role in vehicle simulation, collision test and real-time control of vehicle active systems. To identify the important vehicle dynamic parameters, a systematic parameter identification procedure is studied in this work. In the first step of the procedure, a conceptual parallel manipulator (virtual test rig), which possesses three rotational degrees-of-freedom, is firstly proposed. To realize kinematic characteristics of the conceptual parallel manipulator, the kinematic analysis consists of inverse kinematic and singularity architecture is carried out. Based on the Euler's rotation equations for rigid body dynamics, the dynamic model of parallel manipulator and derivation of measurement matrix for parameter identification are presented subsequently. In order to reduce the sensitivity of parameter identification to measurement noise and other unexpected disturbances, a parameter optimization process of searching for optimal exciting trajectory of parallel manipulator is conducted in the following section. For this purpose, the 321-Euler-angles defined by parameterized finite-Fourier-series are primarily used to describe the general exciting trajectory of parallel manipulator. To minimize the condition number of measurement matrix for achieving better parameter identification accuracy, the unknown coefficients of parameterized finite-Fourier-series are estimated by employing an iterative algorithm based on MATLAB®. Meanwhile, the iterative algorithm will ensure the parallel manipulator still keeps in an achievable working status during the execution of optimal exciting trajectory. It is showed that the proposed procedure and methods in this work can effectively identify the vehicle dynamic parameters and could be an important application of parallel manipulator in the fields of parameter identification and test rig development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parameter%20identification" title="parameter identification">parameter identification</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20manipulator" title=" parallel manipulator"> parallel manipulator</a>, <a href="https://publications.waset.org/abstracts/search?q=singularity%20architecture" title=" singularity architecture"> singularity architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20modelling" title=" dynamic modelling"> dynamic modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=exciting%20trajectory" title=" exciting trajectory"> exciting trajectory</a> </p> <a href="https://publications.waset.org/abstracts/89199/identification-of-vehicle-dynamic-parameters-by-using-optimized-exciting-trajectory-on-3-dof-parallel-manipulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89199.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Structuring Highly Iterative Product Development Projects by Using Agile-Indicators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guenther%20Schuh">Guenther Schuh</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Riesener"> Michael Riesener</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Diels"> Frederic Diels</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, manufacturing companies are faced with the challenge of meeting heterogeneous customer requirements in short product life cycles with a variety of product functions. So far, some of the functional requirements remain unknown until late stages of the product development. A way to handle these uncertainties is the highly iterative product development (HIP) approach. By structuring the development project as a highly iterative process, this method provides customer oriented and marketable products. There are first approaches for combined, hybrid models comprising deterministic-normative methods like the Stage-Gate process and empirical-adaptive development methods like SCRUM on a project management level. However, almost unconsidered is the question, which development scopes can preferably be realized with either empirical-adaptive or deterministic-normative approaches. In this context, a development scope constitutes a self-contained section of the overall development objective. Therefore, this paper focuses on a methodology that deals with the uncertainty of requirements within the early development stages and the corresponding selection of the most appropriate development approach. For this purpose, internal influencing factors like a company’s technology ability, the prototype manufacturability and the potential solution space as well as external factors like the market accuracy, relevance and volatility will be analyzed and combined into an Agile-Indicator. The Agile-Indicator is derived in three steps. First of all, it is necessary to rate each internal and external factor in terms of the importance for the overall development task. Secondly, each requirement has to be evaluated for every single internal and external factor appropriate to their suitability for empirical-adaptive development. Finally, the total sums of internal and external side are composed in the Agile-Indicator. Thus, the Agile-Indicator constitutes a company-specific and application-related criterion, on which the allocation of empirical-adaptive and deterministic-normative development scopes can be made. In a last step, this indicator will be used for a specific clustering of development scopes by application of the fuzzy c-means (FCM) clustering algorithm. The FCM-method determines sub-clusters within functional clusters based on the empirical-adaptive environmental impact of the Agile-Indicator. By means of the methodology presented in this paper, it is possible to classify requirements, which are uncertainly carried out by the market, into empirical-adaptive or deterministic-normative development scopes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agile" title="agile">agile</a>, <a href="https://publications.waset.org/abstracts/search?q=highly%20iterative%20development" title=" highly iterative development"> highly iterative development</a>, <a href="https://publications.waset.org/abstracts/search?q=agile-indicator" title=" agile-indicator"> agile-indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20development" title=" product development"> product development</a> </p> <a href="https://publications.waset.org/abstracts/53509/structuring-highly-iterative-product-development-projects-by-using-agile-indicators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53509.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> The Effect of Degraded Shock Absorbers on the Safety-Critical Stationary and Non-Stationary Lateral Dynamics of Passenger Cars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Schramm">Tobias Schramm</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCnther%20Prokop"> Günther Prokop</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The average age of passenger cars is rising steadily around the world. Older vehicles are more sensitive to the degradation of chassis components. A higher age and a higher mileage of passenger cars correlate with an increased failure rate of vehicle shock absorbers. The most common degradation mechanism of vehicle shock absorbers is the loss of oil and gas. It is not yet fully understood how the loss of oil and gas in twin-tube shock absorbers affects the lateral dynamics of passenger cars. The aim of this work is to estimate the effect of degraded twin-tube shock absorbers of passenger cars on their safety-critical lateral dynamics. A characteristic curve-based five-mass full vehicle model and a semi-physical phenomenological shock absorber model were set up, parameterized and validated. The shock absorber model is able to reproduce the damping characteristics of vehicle twin-tube shock absorbers with oil and gas loss for various excitations. The full vehicle model was used to simulate stationary cornering and steering wheel angle step maneuvers on road classes A to D. The simulations were carried out in a realistic parameter space in order to demonstrate the influence of various vehicle characteristics on the effect of degraded shock absorbers. As a result, it was shown that degraded shock absorbers have a negative effect on the understeer gradient of vehicles. For stationary lateral dynamics, degraded shock absorbers for high road excitations reduce the maximum lateral accelerations. Degraded rear axle shock absorbers can change the understeer gradient of a vehicle in the direction of oversteer. Degraded shock absorbers also lead to increased rolling angles. Furthermore, degraded shock absorbers have a major impact on driving stability during steering wheel angle steps. Degraded rear axle shock absorbers, in particular, can lead to unstable handling. Especially the tire stiffness, the unsprung mass and the stabilizer stiffness influence the effect of degraded shock absorbers on the lateral dynamics of passenger cars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=driving%20dynamics" title="driving dynamics">driving dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20absorber%20degradation" title=" shock absorber degradation"> shock absorber degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=stationary%20and%20nonstationary%20lateral%20dynamics." title=" stationary and nonstationary lateral dynamics."> stationary and nonstationary lateral dynamics.</a> </p> <a href="https://publications.waset.org/abstracts/194638/the-effect-of-degraded-shock-absorbers-on-the-safety-critical-stationary-and-non-stationary-lateral-dynamics-of-passenger-cars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">8</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Sound Source Localisation and Augmented Reality for On-Site Inspection of Prefabricated Building Components</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jacques%20Cuenca">Jacques Cuenca</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Colangeli"> Claudio Colangeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Mroz"> Agnieszka Mroz</a>, <a href="https://publications.waset.org/abstracts/search?q=Karl%20Janssens"> Karl Janssens</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20Riexinger"> Gunther Riexinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20D%27Antuono"> Antonio D'Antuono</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Pandarese"> Giuseppe Pandarese</a>, <a href="https://publications.waset.org/abstracts/search?q=Milena%20Martarelli"> Milena Martarelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Gian%20Marco%20Revel"> Gian Marco Revel</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Barcena%20Martin"> Carlos Barcena Martin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents an on-site acoustic inspection methodology for quality and performance evaluation of building components. The work focuses on global and detailed sound source localisation, by successively performing acoustic beamforming and sound intensity measurements. A portable experimental setup is developed, consisting of an omnidirectional broadband acoustic source and a microphone array and sound intensity probe. Three main acoustic indicators are of interest, namely the sound pressure distribution on the surface of components such as walls, windows and junctions, the three-dimensional sound intensity field in the vicinity of junctions, and the sound transmission loss of partitions. The measurement data is post-processed and converted into a three-dimensional numerical model of the acoustic indicators with the help of the simultaneously acquired geolocation information. The three-dimensional acoustic indicators are then integrated into an augmented reality platform superimposing them onto a real-time visualisation of the spatial environment. The methodology thus enables a measurement-supported inspection process of buildings and the correction of errors during construction and refurbishment. Two experimental validation cases are shown. The first consists of a laboratory measurement on a full-scale mockup of a room, featuring a prefabricated panel. The latter is installed with controlled defects such as lack of insulation and joint sealing material. It is demonstrated that the combined acoustic and augmented reality tool is capable of identifying acoustic leakages from the building defects and assist in correcting them. The second validation case is performed on a prefabricated room at a near-completion stage in the factory. With the help of the measurements and visualisation tools, the homogeneity of the partition installation is evaluated and leakages from junctions and doors are identified. Furthermore, the integration of acoustic indicators together with thermal and geometrical indicators via the augmented reality platform is shown. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20inspection" title="acoustic inspection">acoustic inspection</a>, <a href="https://publications.waset.org/abstracts/search?q=prefabricated%20building%20components" title=" prefabricated building components"> prefabricated building components</a>, <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title=" augmented reality"> augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20source%20localization" title=" sound source localization"> sound source localization</a> </p> <a href="https://publications.waset.org/abstracts/80668/sound-source-localisation-and-augmented-reality-for-on-site-inspection-of-prefabricated-building-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80668.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Characterizing Solid Glass in Bending, Torsion and Tension: High-Temperature Dynamic Mechanical Analysis up to 950 °C</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthias%20Walluch">Matthias Walluch</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Alberto%20Rodr%C3%ADguez"> José Alberto Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Giehl"> Christopher Giehl</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20Arnold"> Gunther Arnold</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Ehgartner"> Daniela Ehgartner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dynamic mechanical analysis (DMA) is a powerful method to characterize viscoelastic properties and phase transitions for a wide range of materials. It is often used to characterize polymers and their temperature-dependent behavior, including thermal transitions like the glass transition temperature Tg, via determination of storage and loss moduli in tension (Young’s modulus, E) and shear or torsion (shear modulus, G) or other testing modes. While production and application temperatures for polymers are often limited to several hundred degrees, material properties of glasses usually require characterization at temperatures exceeding 600 °C. This contribution highlights a high temperature setup for rotational and oscillatory rheometry as well as for DMA in different modes. The implemented standard convection oven enables the characterization of glass in different loading modes at temperatures up to 950 °C. Three-point bending, tension and torsional measurements on different glasses, with E and G moduli as a function of frequency and temperature, are presented. Additional tests include superimposing several frequencies in a single temperature sweep (“multiwave”). This type of test results in a considerable reduction of the experiment time and allows to evaluate structural changes of the material and their frequency dependence. Furthermore, DMA in torsion and tension was performed to determine the complex Poisson’s ratio as a function of frequency and temperature within a single test definition. Tests were performed in a frequency range from 0.1 to 10 Hz and temperatures up to the glass transition. While variations in the frequency did not reveal significant changes of the complex Poisson’s ratio of the glass, a monotonic increase of this parameter was observed when increasing the temperature. This contribution outlines the possibilities of DMA in bending, tension and torsion for an extended temperature range. It allows the precise mechanical characterization of material behavior from room temperature up to the glass transition and the softening temperature interval. Compared to other thermo-analytical methods, like Dynamic Scanning Calorimetry (DSC) where mechanical stress is neglected, the frequency-dependence links measurement results (e.g. relaxation times) to real applications <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20mechanical%20analysis" title="dynamic mechanical analysis">dynamic mechanical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillatory%20rheometry" title=" oscillatory rheometry"> oscillatory rheometry</a>, <a href="https://publications.waset.org/abstracts/search?q=Poisson%27s%20ratio" title=" Poisson's ratio"> Poisson's ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20glass" title=" solid glass"> solid glass</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelasticity" title=" viscoelasticity"> viscoelasticity</a> </p> <a href="https://publications.waset.org/abstracts/156665/characterizing-solid-glass-in-bending-torsion-and-tension-high-temperature-dynamic-mechanical-analysis-up-to-950-c" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156665.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Moving Target Defense against Various Attack Models in Time Sensitive Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Johannes%20G%C3%BCnther">Johannes Günther</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Time Sensitive Networking (TSN), standardized in the IEEE 802.1 standard, has been lent increasing attention in the context of mission critical systems. Such mission critical systems, e.g., in the automotive domain, aviation, industrial, and smart factory domain, are responsible for coordinating complex functionalities in real time. In many of these contexts, a reliable data exchange fulfilling hard time constraints and quality of service (QoS) conditions is of critical importance. TSN standards are able to provide guarantees for deterministic communication behaviour, which is in contrast to common best-effort approaches. Therefore, the superior QoS guarantees of TSN may aid in the development of new technologies, which rely on low latencies and specific bandwidth demands being fulfilled. TSN extends existing Ethernet protocols with numerous standards, providing means for synchronization, management, and overall real-time focussed capabilities. These additional QoS guarantees, as well as management mechanisms, lead to an increased attack surface for potential malicious attackers. As TSN guarantees certain deadlines for priority traffic, an attacker may degrade the QoS by delaying a packet beyond its deadline or even execute a denial of service (DoS) attack if the delays lead to packets being dropped. However, thus far, security concerns have not played a major role in the design of such standards. Thus, while TSN does provide valuable additional characteristics to existing common Ethernet protocols, it leads to new attack vectors on networks and allows for a range of potential attacks. One answer to these security risks is to deploy defense mechanisms according to a moving target defense (MTD) strategy. The core idea relies on the reduction of the attackers' knowledge about the network. Typically, mission-critical systems suffer from an asymmetric disadvantage. DoS or QoS-degradation attacks may be preceded by long periods of reconnaissance, during which the attacker may learn about the network topology, its characteristics, traffic patterns, priorities, bandwidth demands, periodic characteristics on links and switches, and so on. Here, we implemented and tested several MTD-like defense strategies against different attacker models of varying capabilities and budgets, as well as collaborative attacks of multiple attackers within a network, all within the context of TSN networks. We modelled the networks and tested our defense strategies on an OMNET++ testbench, with networks of different sizes and topologies, ranging from a couple dozen hosts and switches to significantly larger set-ups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20security" title="network security">network security</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20sensitive%20networking" title=" time sensitive networking"> time sensitive networking</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20target%20defense" title=" moving target defense"> moving target defense</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20security" title=" cyber security"> cyber security</a> </p> <a href="https://publications.waset.org/abstracts/168898/moving-target-defense-against-various-attack-models-in-time-sensitive-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168898.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Designing Agile Product Development Processes by Transferring Mechanisms of Action Used in Agile Software Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guenther%20Schuh">Guenther Schuh</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Riesener"> Michael Riesener</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Kantelberg"> Jan Kantelberg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the fugacity of markets and the reduction of product lifecycles, manufacturing companies from high-wage countries are nowadays faced with the challenge to place more innovative products within even shorter development time on the market. At the same time, volatile customer requirements have to be satisfied in order to successfully differentiate from market competitors. One potential approach to address the explained challenges is provided by agile values and principles. These agile values and principles already proofed their success within software development projects in the form of management frameworks like Scrum or concrete procedure models such as Extreme Programming or Crystal Clear. Those models lead to significant improvements regarding quality, costs and development time and are therefore used within most software development projects. Motivated by the success within the software industry, manufacturing companies have tried to transfer agile mechanisms of action to the development of hardware products ever since. Though first empirical studies show similar effects in the agile development of hardware products, no comprehensive procedure model for the design of development iterations has been developed for hardware development yet due to different constraints of the domains. For this reason, this paper focusses on the design of agile product development processes by transferring mechanisms of action used in agile software development towards product development. This is conducted by decomposing the individual systems 'product development' and 'agile software development' into relevant elements and symbiotically composing the elements of both systems in respect of the design of agile product development processes afterwards. In a first step, existing product development processes are described following existing approaches of the system theory. By analyzing existing case studies from industrial companies as well as academic approaches, characteristic objectives, activities and artefacts are identified within a target-, action- and object-system. In partial model two, mechanisms of action are derived from existing procedure models of agile software development. These mechanisms of action are classified in a superior strategy level, in a system level comprising characteristic, domain-independent activities and their cause-effect relationships as well as in an activity-based element level. Within partial model three, the influence of the identified agile mechanism of action towards the characteristic system elements of product development processes is analyzed. For this reason, target-, action- and object-system of the product development are compared with the strategy-, system- and element-level of agile mechanism of action by using the graph theory. Furthermore, the necessity of existence of activities within iteration can be determined by defining activity-specific degrees of freedom. Based on this analysis, agile product development processes are designed in form of different types of iterations within a last step. By defining iteration-differentiating characteristics and their interdependencies, a logic for the configuration of activities, their form of execution as well as relevant artefacts for the specific iteration is developed. Furthermore, characteristic types of iteration for the agile product development are identified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activity-based%20process%20model" title="activity-based process model">activity-based process model</a>, <a href="https://publications.waset.org/abstracts/search?q=agile%20mechanisms%20of%20action" title=" agile mechanisms of action"> agile mechanisms of action</a>, <a href="https://publications.waset.org/abstracts/search?q=agile%20product%20development" title=" agile product development"> agile product development</a>, <a href="https://publications.waset.org/abstracts/search?q=degrees%20of%20freedom" title=" degrees of freedom"> degrees of freedom</a> </p> <a href="https://publications.waset.org/abstracts/53775/designing-agile-product-development-processes-by-transferring-mechanisms-of-action-used-in-agile-software-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53775.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> The Effect of Degraded Shock Absorbers on the Safety-Critical Tipping and Rolling Behaviour of Passenger Cars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Schramm">Tobias Schramm</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCnther%20Prokop"> Günther Prokop</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Germany, the number of road fatalities has been falling since 2010 at a more moderate rate than before. At the same time, the average age of all registered passenger cars in Germany is rising continuously. Studies show that there is a correlation between the age and mileage of passenger cars and the degradation of their chassis components. Various studies show that degraded shock absorbers increase the braking distance of passenger cars and have a negative impact on driving stability. The exact effect of degraded vehicle shock absorbers on road safety is still the subject of research. A shock absorber examination as part of the periodic technical inspection is only mandatory in very few countries. In Germany, there is as yet no requirement for such a shock absorber examination. More comprehensive findings on the effect of degraded shock absorbers on the safety-critical driving dynamics of passenger cars can provide further arguments for the introduction of mandatory shock absorber testing as part of the periodic technical inspection. The specific effect chains of untripped rollover accidents are also still the subject of research. However, current research results show that the high proportion of sport utility vehicles in the vehicle field significantly increases the probability of untripped rollover accidents. The aim of this work is to estimate the effect of degraded twin-tube shock absorbers on the safety-critical tipping and rolling behaviour of passenger cars, which can lead to untripped rollover accidents. A characteristic curve-based five-mass full vehicle model and a semi-physical phenomenological shock absorber model were set up, parameterized and validated. The shock absorber model is able to reproduce the damping characteristics of vehicle twin-tube shock absorbers with oil and gas loss for various excitations. The full vehicle model was validated with steering wheel angle sinus sweep driving maneuvers. The model was then used to simulate steering wheel angle sine and fishhook maneuvers, which investigate the safety-critical tipping and rolling behavior of passenger cars. The simulations were carried out in a realistic parameter space in order to demonstrate the effect of various vehicle characteristics on the effect of degraded shock absorbers. As a result, it was shown that degraded shock absorbers have a negative effect on the tipping and rolling behavior of all passenger cars. Shock absorber degradation leads to a significant increase in the observed roll angles, particularly in the range of the roll natural frequency. This superelevation has a negative effect on the wheel load distribution during the driving maneuvers investigated. In particular, the height of the vehicle's center of gravity and the stabilizer stiffness of the vehicles has a major influence on the effect of degraded shock absorbers on the overturning and rolling behaviour of passenger cars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title="numerical simulation">numerical
