    Greenhouse gas (GHG) emissions associated with transportation activities account for approximately 20 percent of all carbon dioxide (co2) emissions globally, making the transportation sector a major contributor to the current global warming. This book focuses on the latest advances in technologies aiming at the sustainable future transportation of people and goods. A reduction in burning fossil fuel and technological transitions are the main approaches toward sustainable future transportation. Particular attention is given to automobile technological transitions, bike sharing systems, supply chain digitalization, and transport performance monitoring and optimization, among others

    Robot Manipulators

    Robot manipulators are developing more in the direction of industrial robots than of human workers. Recently, the applications of robot manipulators are spreading their focus, for example Da Vinci as a medical robot, ASIMO as a humanoid robot and so on. There are many research topics within the field of robot manipulators, e.g. motion planning, cooperation with a human, and fusion with external sensors like vision, haptic and force, etc. Moreover, these include both technical problems in the industry and theoretical problems in the academic fields. This book is a collection of papers presenting the latest research issues from around the world

    From Preface: The 15th International Conference „Dynamical Systems - Theory and Applications” (DSTA 2019, 2-5 December, 2019, Lodz, Poland) gathered a numerous group of outstanding scientists and engineers who deal with widely understood problems of theoretical and applied dynamics. Organization of the conference would not have been possible without great effort of the staff of the Department of Automation, Biomechanics and Mechatronics of the Lodz University of Technology. The patronage over the conference has been taken by the Committee of Mechanics of the Polish Academy of Sciences and Ministry of Science and Higher Education of Poland. It is a great pleasure that our event was attended by over 180 researchers from 35 countries all over the world, who decided to share the results of their research and experience in different fields related to dynamical systems. This year, the DSTA Conference Proceedings were split into two volumes entitled „Theoretical Approaches in Non-Linear Dynamical Systems” and „Applicable Solutions in Non-Linear Dynamical Systems”. In addition, DSTA 2019 resulted in three volumes of Springer Proceedings in Mathematics and Statistics entitled „Control and Stability of Dynamical Systems”, „Mathematical and Numerical Approaches in Dynamical Systems” and „Dynamical Systems in Mechatronics and Life Sciences”. Also, many outstanding papers will be recommended to special issues of renowned scientific journals.Cover design: Kaźmierczak, MarekTechnical editor: Kaźmierczak, Mare

    The files on this record represent the various databases that originally composed the CD-ROM issue of "Abstracts on Radio Direction Finding" database, which is now part of the Dudley Knox Library's Abstracts and Selected Full Text Documents on Radio Direction Finding (1899 - 1995) Collection. (See Calhoun record https://calhoun.nps.edu/handle/10945/57364 for further information on this collection and the bibliography). Due to issues of technological obsolescence preventing current and future audiences from accessing the bibliography, DKL exported and converted into the three files on this record the various databases contained in the CD-ROM. The contents of these files are: 1) RDFA_CompleteBibliography_xls.zip [RDFA_CompleteBibliography.xls: Metadata for the complete bibliography, in Excel 97-2003 Workbook format; RDFA_Glossary.xls: Glossary of terms, in Excel 97-2003 Workbookformat; RDFA_Biographies.xls: Biographies of leading figures, in Excel 97-2003 Workbook format]; 2) RDFA_CompleteBibliography_csv.zip [RDFA_CompleteBibliography.TXT: Metadata for the complete bibliography, in CSV format; RDFA_Glossary.TXT: Glossary of terms, in CSV format; RDFA_Biographies.TXT: Biographies of leading figures, in CSV format]; 3) RDFA_CompleteBibliography.pdf: A human readable display of the bibliographic data, as a means of double-checking any possible deviations due to conversion

    Development of Integrated Systematic Approach Conceptual Design and TRIZ using Safety Principles in Embodiment Design for Complex Products

    Get PDF
    There are many conceptual design methods available for the engineering design world. Of all the methods, two significant methods are chosen to be integrated for the effective conceptual design process. These are the systematic Approach (SA) and the Theory of Inventive Problem Solving (TRIZ). SA consists of the Systematic Approach Conceptual Design (SACD) and Systematic Approach Embodiment Design (SAED), which were established by Pahl and Beitz, and widely used in industry and by academics. In addition, TRIZ is actively practiced in companies that wish to innovate creative and inventive designs. Although both methods have contrasting features there are some similarities that enable them to be united and harmonized. Many scholars have attempted to develop a new methodology by combining SA and TRIZ but none have integrated the safety principles of SAED with the inventive principles of TRIZ. In designing complex artefacts, constraints and safety are the main issues in the design change process. Implementing safety at a later stage might compromise the concept ideas and end up being a conventional and common concept design. This study developed a conceptual design method, TRIZ-SA, with a specialized safety approach combining the Function Constraint Model (FCM) and the Safety Principle Guide (SPG) as the method’s tools. The method aims to encourage the intervention of safety in the conceptual design process to stimulate ideas for solutions that are efficient in safety and creativity. The development of TRIZ-SA is through qualitative content analysis of the work of many scholars and patents. The pairwise comparative analysis is also conducted in the development of the 8-Step. The validation of the combined method for the safety approach is done through a conceptual design case study on the geometric and shape design of an aircraft’s Main Landing Gear (MLG). The combination of SA and TRIZ resulted in an easier solution finding process for an artefact that requires high concern in terms of safety, thereby opening up a new perspective in the designing concept of a complex artefact and shaping the design path towards a safe and creative concept design. The implications of this study will help designers optimize and develop a safe and inventive concept design in an effective and creative way
