  abstract  = {Die vorliegende Untersuchung gilt der Mikro- und Makrotypografie der seit 125 Jahren erscheinenden katholischen Verbandszeitschrift "Academia". F{\"u}r die graphologischen und pal{\"a}ographischen Besonderheiten wird eine Hermeneutik vorgeschlagen. Das hier erforschte Druckbild repr{\"a}sentiert mit einer Auflage von 30.000 Exemplaren im achtw{\"o}chigen Erscheinungsrhythmus den Cartellverband der Katholischen Deutschen Studentenverbindungen (CV). So illustriert und visualisiert dieses Druckbild mit seiner typografischen Performance zugleich den mitgliederst{\"a}rksten Akademikerverband Europas.},

  abstract  = {Singapore has a unique and proactive approach towards managing the national transport system. This article explores the integrative approach of carsharing into the overall transport system from an individual sustainable mobility perspective. The authors argue that for Singapore, taxi services are the strongest competitor for the establishment of free-floating carsharing systems. Low taxi fares and a high distribution rate provide easy access for consumers and show great advantages in correspondence with the prevalent transport measures. Furthermore, the Singaporean government considers taxi services as part of public transport that helps bridging public transportation gaps in door-to-door travel. The article draws on literature review and expert interviews to evaluate the current market conditions and analyse the pros and cons of carsharing systems and taxi services as integrated part of the public transport system. The authors conclude by stating that from a sustainable perspective, the goal is to replace private car ownership. Provision of multi modal choices and therefore co-existence of different individual transport opportunities is indispensable.},

  abstract  = {This paper presents an alternative approach for obtaining a converse Lyapunov theorem for discrete-time systems. The proposed approach is constructive, as it provides an explicit Lyapunov function. The developed converse theorem establishes existence of global Lyapunov functions for globally exponentially stable (GES) systems and semi-global practical Lyapunov functions for globally asymptotically stable systems. Furthermore, for specific classes of sys- tems, the developed converse theorem can be used to establish non-conservatism of a particular type of Lyapunov functions. Most notably, a proof that conewise linear Lyapunov functions are non-conservative for GES conewise linear systems is given and, as a by-product, tractable construction of polyhedral Lyapunov functions for linear systems is attained.},
