Künstliche Intelligenz in der Fleischhygiene - Entwicklung eines Detektionssystems für Kontaminationen mit Kamerasystemen
No full textOld but Gold : Ein Handbuch zur kreativen Begleitung im Alter
Get PDFDiese Bachelorarbeit beschäftigt sich mit dem Älterwerden, mit der Demenz und der Bedeutung der kreativen Arbeit für Senioren. Auf Grundlage von im Studium erlernten Gestaltungsmethoden wurden verschiedene Aufgaben entwickelt, die die Sinneswahrnehmungen, das Selbstbewusstsein und die Kreativität der Senioren stärken. Die Aufgaben wurden in einem Handbuch zusammenfasst, welches Angehörigen und Pflegern den Umgang mit Senioren erleichtern soll und die Möglichkeit bietet, gemeinsam neue Erinnerungen zu schaffen.This bachelor thesis deals with aging, dementia, and the significance of creative work for seniors. Based on design methods learned during the study, various tasks have been developed to strengthen the sensory perceptions, self-esteem, and creativity of seniors. These tasks have been summarized in a handbook to help family members and caregivers engage better with seniors, allowing them to create new memories together
Additively manufactured pressure sensor for embedding in 3D-printed below-knee orthosis
No full textAdditive manufacturing enables direct prototyping of complex 3D-objects that are difficult to manufacture using conventional methods. It is widely used to fabricate cost-efficient prototypes and portrays as a bridging technology to connect different scientific and industrial fields, e.g. Engineering, Medicine, etc. Consequently, additive manufacturing finds its applications in the production of patient-specific orthoses. This paper discusses the application of the stereolithography apparatus process to develop a pressure sensor based on an optical waveguide principle to embed into a below-knee orthosis. For Orthopaedic patients, the below-knee orthosis must be adjusted to the lower leg at regular intervals due to anthropometric changes in patient’s body to achieve proper mobility and correct load. Currently, this alteration relies on the patient’s estimation of support load and is only sub-optimal. Hence, the concept of developing an intelligent orthosis with a novel embedded optical system to monitor the exact support load at the neuralgic is proposed
Simulation of a Longitudinal Control System for an Automated Driving Self-Stabilized Monorail Vehicle
No full textCurrently, numerous single track railway lines are disused due to economic reasons. One way they could be reactivated for bidirectional on demand traffic is by small cabin-like vehicles, lateral stabilized by a system of control moment gyroscopes and a moveable mass. Regarding such a vehicle, there is currently no reference in comparison with other vehicles and no experimental experience or the like. To ensure the functionality and safety of the vehicle even before its realization, a model-based design is carried out for development, analysis, optimization and testing. This paper is focused on the co-simulation of such a vehicle that is controlled by a longitudinal control. In order to take into account the complex interaction between the longitudinal dynamics and the running gear, the entire system must be considered here including the wheel/rail interaction. Co-simulations are performed considering both the mechanical model of the vehicle and the control of the longitudinal dynamics of the overall system. The simulation results show that functionality and safe operation can be ensured by the vehicle longitudinal controls. As a result, the simulation and the measurement of the real system show a good match. By means of HIL and co-simulations, function tests could be shifted to earlier development stages, in order to accelerate the overall development
Yeast filtration with rotating membrane filtration – a new approach for an economical recovery of beer form surplus yeast
No full textThe recovery of beer from surplus yeast is to date an economical business case only for large breweries. In this work, a here novel process with rotating ceramic microfiltration membranes is used. This allows a very high lift force to be achieved while still maintaining a small transmembrane pressure to reduce the formation of a fouling layer. The results show that long running times (between cleanings) are possible, limited only by the change in the rheological properties of the suspension due to thickening. From a so-called "Inflexion Point" (IF), the filtration behavior changes abruptly. The aim of the work was therefore to use machine learning aided modeling to predict the IF from experimental data in order to optimize the process and to achieve the most economical conditions. The economic efficiency depends on the space-time yields. The results show that a significant improvement in economic efficiency could be possible with the help of modeling and this special kind of filtration technology. However, the economic efficiency depends finally on the conditions in each individual brewery

Hygroscopic behavior of thermo-hygro-mechanical (THM) densified oil palm sawn timber
No full textTo facilitate the drying process and enhance the properties of oil palm wood, oil palm boards were mechanically pre-dewatered and thermo-hygro-mechanically (THM) densified. The thickness of the boards was reduced with compression ratios of 40%, 60% and 75%. Since densified wood tends to recover from compression, especially under humid conditions, this study examined the set-recovery and the hygroscopic behavior of THM densified oil palm wood. The equilibrium moisture content (EMC), differential swelling and swelling coefficient, linear swelling and shrinkage as well as the differential swelling anisotropy were determined under climate conditions with different relative humidity (RH) (20°C/35% RH, 20°C/65% RH and 20°C/85% RH). The maximum swelling was measured after water soaking and the remaining set-recovery was evaluated after re-drying at 103°C. The EMC was reduced by the THM process by around 20%. In the direction of compression (thickness), the densified specimens show higher values for all analyzed swelling and shrinkage parameters than the undensified specimens from the equivalent position within the trunk. The maximum swelling in thickness of 22–38% during water soaking is mostly reversed by shrinkage during re-drying and a comparably low remaining set-recovery of 3–8% is measured at oven dry condition
