  abstract  = {Electric trains are considered one of the most eco-friendly and safest means of transportation. Catenary poles are used worldwide to support overhead power lines for electric trains. The performance of the catenary poles has an extensive influence on the integrity of the train systems and, consequently, the connected human services. It became a must nowadays to develop SHM systems that provide the instantaneous status of catenary poles in- service, making the decision-making processes to keep or repair the damaged poles more feasible. This study develops a data-driven, model-free approach for status monitoring of cantilever structures, focusing on pre-stressed, spun-cast ultrahigh-strength concrete catenary poles installed along high-speed train tracks. The pro-posed approach evaluates multiple damage features in an unfied damage index, which leads to straightforward interpretation and comparison of the output. Besides, it distinguishes between multiple damage scenarios of the poles, either the ones caused by material degradation of the concrete or by the cracks that can be propagated during the life span of the given structure. Moreover, using a logistic function to classify the integrity of structure avoids the expensive learning step in the existing damage detection approaches, namely, using the modern machine and deep learning methods. The findings of this study look very promising when applied to other types of cantilever structures, such as the poles that support the power transmission lines, antenna masts, chimneys, and wind turbines.},

  abstract  = {Thin-walled cylindrical composite shell structures are often applied in aerospace for lighter and cheaper launcher transport system. These structures exhibit sensitivity to geometrical imperfection and are prone to buckling under axial compression. Today the design is based on NASA guidelines from the 1960's [1] using a conservative lower bound curve embodying many experimental results of that time. It is well known that the advantages and different characteristics of composites as well as the evolution of manufacturing standards are not considered apporopriately in this outdated approach. The DESICOS project was initiated to provide new design guidelines regarding all the advantages of composites and allow further weight reduction of space structures by guaranteeing a more precise and robust design. Therefore it is necessary among other things to understand how a cutout with different dimensions affects the buckling load of a thin-walled cylindrical shell structure in combination with initial geometric imperfections. This work is intended to identify a ratio between the cutout characteristic dimension (in this case the cutout diameter) and the structure characteristic dimension (in this case the cylinder radius) that can be used to tell if the buckling structure is dominated by initial imperfections or is dominated by the cutout.},

  abstract  = {Der Bedarf an leistungsf{\"a}higen Hochgeschwindigkeits-Glasfasernetzen ist in den letzten Jahren, insbesondere aufgrund der zunehmenden Nutzung von Internet-basierten Diensten, rapide gestiegen. Eine umfassende Planung von neu zu errichtenden Glasfasernetzen im Sinne eines kosteng{\"u}nstigen Breitbandausbaus ist jedoch h{\"a}ufig mit hohem Aufwand verbunden. Die Auswahl m{\"o}glicher Kabelwege und die anschließende Kalkulation der Installationskosten werden heute in der Regel durch computerbasierte Verfahren unterst{\"u}tzt, wobei allerdings die Installationspl{\"a}ne und die Installationskosten getrennt voneinander dargestellt werden, was wiederum die computergest{\"u}tzte Planung sowie weitere Optimierungsans{\"a}tze erschwert. Dieses Arbeitspapier beschreibt ein Konzept f{\"u}r ein modulares Softwaresystem zur computergest{\"u}tzten Planung, Kostenkalkulation und Visualisierung von Glasfasernetzen, das eine integrierte Darstellung von Installationspl{\"a}nen und Installationskosten erm{\"o}glicht. Anstelle der herk{\"o}mmlichen Darstellung von Installationspl{\"a}nen, die in der Regel alle geplanten Kabelwege einfarbig auf einer Landkarte visualisiert, wird ein Farbschema zur Anzeige der Installationskosten in Installationspl{\"a}nen eingesetzt. Das Konzept wird prototypisch implementiert und durch ein Anwendungsbeispiel, das die Planung eines Glasfasernetzes innerhalb eines Siedlungsgebietes behandelt, validiert. Die integrierte, farbige Darstellung der Installationskosten in Installationspl{\"a}nen erm{\"o}glicht eine effiziente Identifikation der kostenintensiven Bauabschnitte und bef{\"o}rdert kostenoptimierte Planungsans{\"a}tze. Die intuitive Visualisierung vereinfacht somit die akkurate und kostenoptimierte Planung von Glasfasernetzen.},

  abstract  = {Lithium-ion (Li-ion) batteries are currently considered as vital components for advances in mobile technologies such as those in communications and transport. Nonetheless, Li-ion batteries suffer from temperature rises which sometimes lead to operational damages or may even cause fire. An appropriate solution to control the temperature changes during the operation of Li-ion batteries is to embed batteries inside a paraffin matrix to absorb and dissipate heat. In the present work, we aimed to investigate the possibility of making paraffin nanocomposites for better heat management of a Li-ion battery pack. To fulfill this aim, heat generation during a battery charging/discharging cycles was simulated using Newman's well established electrochemical pseudo-2D model. We couple this model to a 3D heat transfer model to predict the temperature evolution during the battery operation. In the later model, we considered different paraffin nanocomposites structures made by the addition of graphene, carbon nanotubes, and fullerene by assuming the same thermal conductivity for all fillers. This way, our results mainly correlate with the geometry of the fillers. Our results assess the degree of enhancement in heat dissipation of Li-ion batteries through the use of paraffin nanocomposites. Our results may be used as a guide for experimental set-ups to improve the heat management of Li-ion batteries.},
