At the same time, following classic methods to increase speed and reduce energy consumption of these devices becomes increasingly difficult, bringing alternative methods into focus. One of these methods is approximate computing which utilizes the fact that small errors in computations are acceptable in many applications in order to allow acceleration of these computations or to increase energy efficiency. This thesis develops elements of a workflow that can be followed to apply approximate computing to existing applications. It proposes a novel heuristic approach to the localization of code paths that are suitable to approximate computing based on findings in recent research. Additionally, an approach to identification of approximable instructions within these code paths is proposed and used to implement simulation of approximation. The parts of the workflow are implemented with the goal to lay the foundation for a partly automated toolflow. Evaluation of the developed techniques shows that the proposed methods can help providing a convenient workflow, facilitating the first steps into the application of approximate computing."}],"supervisor":[{"last_name":"Plessl","first_name":"Christian","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","id":"16153"}],"citation":{"mla":"Lass, Michael. <i>Localization and Analysis of Code Paths Suitable for Acceleration Using Approximate Computing</i>.

Model-based Systems Engineering (MBSE) coordinates these disciplines throughout the development by means of discipline-spanning processes and system models. Such a system model provides a common understanding of the system under development and serves as a starting point for the discipline-specific development. An integral part of MBSE is the requirements engineering on the system level. However, for the discipline-specific development to start, these requirements need to be refined, e.g., into specific requirements for the embedded software. Since existing MBSE approaches lack support for this refinement step, we conceived a systematic transition from MBSE to model-based software requirements engineering, which we present in this paper. We automated the steps of the transition where possible, in order to avoid error-prone and time-consuming manual tasks. We illustrate the approach with an example of an automotive embedded system.\r\n","lang":"eng"}],"citation":{"bibtex":"@inproceedings{Holtmann_Bernijazov_Meyer_Schmelter_Tschirner_2015, title={Integrated systems engineering and software requirements engineering for technical systems}, DOI={<a href=\"https://doi.org/10.1145/2785592.2785597\">10.1145/2785592.2785597</a>}, booktitle={Proceedings of the 2015 International Conference on Software and System Process}, author={Holtmann, Jörg and Bernijazov, Ruslan and Meyer, Matthias and Schmelter, David and Tschirner, Christian}, year={2015} }","ama":"Holtmann J, Bernijazov R, Meyer M, Schmelter D, Tschirner C.

Especially the temperature history during the build and cooling phase is decisive for powder ageing effects and the development of part quality characteristics. In this work, a measurement system for three-dimensional in-process temperature measurements is set up and the influence of different parameters on the inner part cake temperature distribution and history is analyzed. Important factors are not only geometrical build job parameters like the part packing density and build height, but also process parameters like the layer thickness and bulk powder density. Individual in-process temperature profiles at different positions within a part cake are finally correlated with powder ageing effects. The results of this work help to understand the temperature history dependency of powder and part properties and can therefore be used to develop optimized process controls.","lang":"eng"}],"publication":"26th Annual International Solid Freeform Fabrication Symposium","citation":{"mla":"Josupeit, Stefan, and Hans-Joachim Schmid. “Temperature History within Laser Sintered Part Cakes and Its Influence on Process Quality.” <i>26th Annual International Solid Freeform Fabrication Symposium</i>, vol. 26, 2015, pp. 190–99, doi:<a href=\"http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf\">http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf</a>.","apa":"Josupeit, S., &#38; Schmid, H.-J.

Hence, it needs to be refreshed with new material for further build cycles. In application, refresh rates of about 50 % are commonly used. In this work, the recycling optimized material PA 2221 from EOS is analyzed along a series of 13 build and refresh cycles using a reduced refresh rate of 32 %. Before and after every build, the powder is analyzed regarding melt properties determined by MVR and DSC measurements. Thereby, in-process ageing effects are investigated and the steady-state conditions are determined accordingly. In addition, powder properties are directly linked to resulting mechanical and geometrical part properties. Key findings are a robust DSC measurement method for polyamide 12 powder, constant “circulated” material properties after three build/refresh cycles and robust tensile properties along the whole tested powder life cycle. As a result, process conditions of PA 2221 using reduced refresh rates can be derived from this work."}],"date_created":"2021-05-14T07:46:18Z","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"type":"conference","author":[{"full_name":"Josupeit, Stefan","first_name":"Stefan","last_name":"Josupeit"},{"full_name":"Lohn, Johannes","last_name":"Lohn","first_name":"Johannes"},{"last_name":"Hermann","first_name":"E.","full_name":"Hermann, E."},{"full_name":"Gessler, Monika","first_name":"Monika","last_name":"Gessler"},{"full_name":"Tenbrink, S.","last_name":"Tenbrink","first_name":"S."},{"first_name":"Hans-Joachim","last_name":"Schmid","full_name":"Schmid, Hans-Joachim","id":"464"}],"year":"2015","status":"public","title":"Material Properties of Laser Sintered Polyamide 12 as Function of Build Cycles Using Low Refresh Rates","intvolume":"        26","date_updated":"2022-01-06T06:55:28Z","_id":"22187","language":[{"iso":"eng"}],"page":"540-549","volume":26,"doi":"http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-43-Josupeit.pdf","user_id":"71545"},{"department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"type":"conference","date_created":"2021-05-14T07:46:20Z","abstract":[{"lang":"eng","text":"The layered structure of Additive Manufacturing processes results in a stairstepping effect of the surface topographies. In general the impact of this effect strongly depends on the build angle of a surface, whereas the overall surface roughness is caused by the resolution of the specific AM process. The aim of this work is the prediction of the surface quality in dependence of the building orientation of a part. These results can finally be used to optimize the orientation to get a desired surface quality. As not every area of a part can be optimized, a predetermination of areas can be used to improve the surface quality of important areas. The model uses the digital STL format of a part as this is necessary for all AM machines to build it. Each triangle is assigned with a roughness value and by testing different orientations the best one can be found. This approach needs a database for the surface qualities. This must be done separately for each Additive Manufacturing process and is shown exemplary with a surface topography simulation for the laser sintering process."}],"citation":{"bibtex":"@inproceedings{Delfs_Toews_Schmid_2015, title={Surface roughness optimized alignment of parts for additive manufacturing processes}, volume={26}, DOI={<a href=\"http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-107-Delfs.pdf\">http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-107-Delfs.pdf</a>}, booktitle={26th Annual International Solid Freeform Fabrication Symposium}, author={Delfs, Patrick and Toews, Marcel and Schmid, Hans-Joachim}, year={2015}, pages={1334–1344} }","ama":"Delfs P, Toews M, Schmid H-J.

Design/methodology/approach – First, a process-independent method for the development of Design Rules was worked out. Therefore, geometrical standard elements and attributes that characterize the elements’ shapes have been defined. Next, the standard elements have been manufactured with different attribute values with Laser Sintering, Laser Melting and Fused Deposition Modeling, and their geometrical quality was examined. From the results, Design Rules for additive manufacturing were derived and summarized in a catalogue. Findings – Due to the process independent method, Design Rules were developed that apply for the different considered additive manufacturing technologies equally. These Design Rules are completely function-independent and easily transferable to individual part designs. Research limitations/implications – The developed Design Rules can only apply for the considered boundary conditions. To extend the Design Rules’ validity, their applicability should be proven for other boundary conditions. Practical implications – The developed Design Rules practically support the design of technical parts. Additionally they can be used for training and teaching in the field of “design for additive manufacturing”. Originality/value – The developed Design Rules constitute a first step toward general Design Rules for Additive Manufacturing. Thus, they might form a suitable basis for further scientific approaches, and the Design Rules can be used to set up teaching documentations for lessons and seminars."}],"date_created":"2021-06-15T11:09:20Z","department":[{"_id":"9"},{"_id":"146"},{"_id":"219"},{"_id":"624"}],"type":"journal_article","status":"public","_id":"22394","publisher":"Emerald Group Publishing Limited","page":"662-670","volume":21,"user_id":"38077","citation":{"apa":"dell’Aere, G., &#38; Zimmer, D.
