In the context of the Corona pandemic and its impact on teaching like digital lectures and exercises a new concept especially for freshmen in demanding courses of Smart Building Engineering became necessary. As there were hardly any face-to-face events at the university, the new teaching concept should enable a good start into engineering studies under pandemic conditions anyway and should also replace the written exam at the end. The students should become active themselves in small teams instead of listening passively to a lecture broadcast online with almost no personal contact. For this purpose, a role play was developed in which the freshmen had to work out a complete solution to the realistic problem of designing, construction planning and implementing a small guesthouse. Each student of the team had to take a certain role like architect, site manager, BIM-manager, electrician and the technitian for HVAC installations. Technical specifications must be complied with, as well as documentation, time planning and cost estimate. The final project folder had to contain technical documents like circuit diagrams for electrical components, circuit diagrams for water and heating, design calculations and components lists. On the other hand construction schedule, construction implementation plan, documentation of the construction progress and minutes of meetings between the various trades had to be submitted as well. In addition to the project folder, a model of the construction project must also be created either as a handmade model or as a digital 3D-model using Computer-aided design (CAD) software. The first steps in the field of Building information modelling (BIM) had also been taken by creating a digital model of the building showing the current planning status in real time as a digital twin. This project turned out to be an excellent training of important student competencies like teamwork, communication skills, and self -organisation and also increased motivation to work on complex technical questions. The aim of giving the student a first impression on the challenges and solutions in building projects with many different technical trades and their points of view was very well achieved and should be continued in the future.
Nowadays modern high-performance buildings and facilities are equipped with monitoring systems and sensors to control building characteristics like energy consumption, temperature pattern and structural safety. The visualization and interpretation of sensor data is typically based on simple spreadsheets and non-standardized user-oriented solutions, which makes it difficult for building owners, facility managers and decision-makers to evaluate and understand the data. The solution of this problem in the future are integrated BIM-Sensor approaches which allow the generation of BIM models incorporating all relevant information of monitoring systems. These approaches support both the dynamic visualization of key structural performance parameters, the effective long-term management of sensor data based on BIM and provide a user-friendly interface to communicate with various stakeholders. A major benefit for the end user is the use of the BIM software architecture, which is the future standard anyway. In the following, the application of the integrated BIM-Sensor approach is illustrated for a typical industrial facility as a part of an early warning and rapid response system for earthquake events currently developed in the research project “ROBUST” with financial support by the German Federal Ministry for Economic Affairs and Energy (BMWI).
Multisensorisches Branding bezeichnet die Gestaltung für mindestens zwei Sinne.
Diese Bachelorarbeit beinhaltet daher ein Konzept, um sehbehinderten Menschen und Blinden das Branding einer Marke im Bereich der Bekleidungsindustrie zugänglich zu machen.
Durch die gezielte Kombination von Haptik und Optik ist im Rahmen dieser Arbeit eine Bekleidungsmarke entstanden, deren Textilien jegliche Informationen für sehbehinderte und blinde Menschen enthalten, ohne dabei auf eine ansprechende Optik für Sehende zu verzichten. Vor allem durch neu entwickelte Open Source Symbole, die fühlbar sind, und einen Barcode wird Betroffenen in Zukunft der Kauf von Bekleidung sowie der Waschvorgang erleichtert.
Reinforced concrete frames with masonry infill walls are popular form of construction all over the world as well in seismic regions. While severe earthquakes can cause high level of damage of both reinforced concrete and masonry infills, earthquakes of lower to medium intensity some-times can cause significant level of damage of masonry infill walls. Especially important is the level of damage of face loaded infill masonry walls (out-of-plane direction) as out-of-plane load cannot only bring high level of damage to the wall, it can also be life-threating for the people near the wall. The response in out-of-plane direction directly depends on the prior in-plane damage, as previous investigation shown that it decreases resistance capacity of the in-fills. Behaviour of infill masonry walls with and without prior in-plane load is investigated in the experimental campaign and the results are presented in this paper. These results are later compared with analytical approaches for the out-of-plane resistance from the literature. Conclusions based on the experimental campaign on the influence of prior in-plane damage on the out-of-plane response of infill walls are compared with the conclusions from other authors who investigated the same problematic.
Thrombogenic complications are a main issue in mechanical circulatory support (MCS). There is no validated in vitro method available to quantitatively assess the thrombogenic performance of pulsatile MCS devices under realistic hemodynamic conditions. The aim of this study is to propose a method to evaluate the thrombogenic potential of new designs without the use of complex in-vivo trials. This study presents a novel in vitro method for reproducible thrombogenicity testing of pulsatile MCS systems using low molecular weight heparinized porcine blood. Blood parameters are continuously measured with full blood thromboelastometry (ROTEM; EXTEM, FIBTEM and a custom-made analysis HEPNATEM). Thrombus formation is optically observed after four hours of testing. The results of three experiments are presented each with two parallel loops. The area of thrombus formation inside the MCS device was reproducible. The implantation of a filter inside the loop catches embolizing thrombi without a measurable increase of platelet activation, allowing conclusions of the place of origin of thrombi inside the device. EXTEM and FIBTEM parameters such as clotting velocity (α) and maximum clot firmness (MCF) show a total decrease by around 6% with a characteristic kink after 180 minutes. HEPNATEM α and MCF rise within the first 180 minutes indicate a continuously increasing activation level of coagulation. After 180 minutes, the consumption of clotting factors prevails, resulting in a decrease of α and MCF. With the designed mock loop and the presented protocol we are able to identify thrombogenic hot spots inside a pulsatile pump and characterize their thrombogenic potential.
Wir alle haben schon einmal von ihnen gehört. Die einen kennen sie aus dem Geschichtsunterricht, die anderen haben sie vielleicht auch schon mal bewusst oder unbewusst auf der Straße gesehen. Einige sind es sogar selbst. Die Rede ist von jüdischen Menschen in Deutschland.
In unserer Bundesrepublik wird die jüdische Bevölkerung unausweichlich mit dem Gedanken des Holocausts verbunden. Jüdinnen und Juden wird somit eine Identität zugesprochen, mit der sie nichts zu tun haben. Es findet eine Stigmatisierung statt. Dabei sind jüdische Menschen heutzutage so divers wie noch nie. Das Printmedium »Ich sehe was, was Du nicht siehst« beleuchtet diese selten wahrgenommene Diversität und zeigt durch spannende Interviews eine jüdische Welt, die außerhalb der NS-Verbrechen liegt. Darüber hinaus findet man Informationen zu verschiedenen jüdischen Bräuchen, historischen Ereignissen und interessanten Infografiken.
Hyphan ist ein modulares System, welches sich aus diversen Grundelementen aufbaut. Die Möglichkeiten des Aufbaus sind vielseitig und Umfangreich. Achsiale- sowie lineare Erweiterung sorgen für ein Modul Umfang, der zahlreiche Fläche erschaffen kann. So kann Länge und Tiefe eines Objekts umfangreich sowie vielfältig gestaltet werden. Hyphan wendet sich an die Bedürfnisse der Neuen Generationen, versucht flexibel in seiner Form zu sein und zuverlässig, langlebig und qualitativ in seinem Material. Durch die Diskussion über die neuen Formen der Mobilität und dem Nachhaltigkeitsaspekt sehe ich in der Gestaltung von urbanen Knotenpunkten und ihren Interior sehr großes Potenzial für Hyphan.
