Model-based Traceability System Development for Complex Manufacturing Applying Blockchain and Graphs
(2023)
Traceability systems are the key enablers to smart manufacturing, as they provide transparency and structured documentation along with a product’s value generation flow. With rising regulatory and organizational requirements, ...
Laser-induced Breakdown Spectroscopy (LIBS) as a diagnostics tool for biological tissue analysis
(2023)
In this thesis, the emerging analytical technique laser‐induced breakdown spectroscopy(LIBS) is investigated as a diagnostic tool for biological tissues analysis. The two main objectives of the work are using LIBS to provide ...
Relation of Particle Motion and Process Zone Formation as a Basis for Sensing Approaches within PBF-LB/M
(2023)
Laser powder bed fusion of metals by a laser beam (PBF-LB/M), due to its industrial applicability, represents a promising additive manufacturing technology for future production. The layerwise and selective melting of a ...
Remote photoacoustic sensing using speckle-analysis for biomedical imaging
(2023)
In this thesis the simple, contact-free speckle-analysis is investigated for its application in photoacoustic detection. First, a simulation model is created which theoretically confirms the detectability of photoacoustic ...
Laser drop on demand joining as bonding method for electronics assembly and packaging with high thermal requirements
(2022)
In the scope of this work, a novel joining process was developed and investi-gated from both an application-driven and an academic point of view. The process utilises laser radiation to melt a CuSn-braze preform, which is ...
Totally Integrated Ecology Management for Resource Efficient and Eco-Friendly Production
(2021)
Energy and environment management is becoming increasingly important for the companies, and for the whole society. Increasing energy prices and the climate change are the main drivers behind this phenomenon. Industrial ...
Skin-equivalent opto-/elastofluidic in-vitro microphysiological vascular models for translational studies of optical biopsies
(2022)
The skin equivalent opto-/elastofluidic in-vitro microphysiological vascular models are prepared as the functional validation test charts to evaluate the correctness of the bio-optical measurements/imaging. The opto-/elastofluidic ...
Closed-Loop Control of a Storage-Supported Hybrid Compensation System for Improving the Power Quality in Medium Voltage Networks
(2021)
Both the operation of power electronic feeders as well as consumers in electrical grids and the transition to electricity generation based on renewable plants create challenges with regard to voltage quality in electrical ...
Multi-Objective Process Optimization for Overpressure Reflow Soldering in Electronics Production
(2021)
Surface Mount Technology (SMT) is the primary method of permanently mounting electronic components on a substrate. A decisive improvement in the quality of the connection technologies is achieved by increasing the reliability ...
Machine learning and hyper spectral imaging: multi spectral endoscopy in the gastro intestinal tract towards hyper spectral endoscopy
(2021)
Worldwide, carcinomas are the second leading cause of death after cardiovascular diseases. Of these, more than 25 % are caused by cancer in the gastrointestinal tract. However, screening still misses about 20 % of carcinomas. ...
Evaluation of failure behaviour of sheet metals
(2020)
The full exploitation of sheet metal formability is crucial for process optimization. This applies in particular to the automotive industry, in which the current trend is in the development of lightweight structures. ...
