3D Printers as Sociable Technologies: Taking Appropriation Infrastructures to the Internet of Things
(2017)
The aim of this thesis is to investigate and optimize the camera system which is used for Filtered Rayleigh Scattering (FRS) measurement systems. Theoretical considerations about the integration of interference filters explain state-of-the-art accuracy limitations. Based on that promising modifications of the established FRS system are presented: test results indicate that frequency fringes - artifacts distorting FRS scans - are minimized by positioning the spectral bandpass filter between camera and first lens. As a tradeoff, the signal level decreases by 70 % to 75% depending on the beam path through the molecular filter. Furthermore, reference measurements without a bandpass filter account for a non-negligible iodine fluorescence background of about 1% of typical signal levels. All things considered following these results FRS systems can now be systematically optimized towards specific measurement tasks.

Solar energy is one option to serve the rising global energy demand with low environmental impact. Building an energy system with a considerable share of solar power requires long-term investment and a careful investigation of potential sites. Therefore, understanding the impacts from varying regionally and locally determined meteorological conditions on solar energy production will influence energy yield projections.
Reliable and regional differentiated power forecasts are required to guarantee an efficient and economic energy transition towards renewable energies. Amongst other renewable energy technologies, e.g. wind mills, photovoltaic (PV) systems are an essential component of this transition being cost-efficient and simply to install. Reliable power forecasts are however required for a grid integration of photovoltaic systems, which among other data requires high-resolution spatio-temporal global irradiance data.
Funktionseinschränkungen nach erworbener Hirnschädigung können die Mobilität der Betroffenen beeinträchtigen und zu gravierenden Änderungen des Lebensstils bis hin zur Inaktivität führen. Es ist davon auszugehen, dass ein inaktiver Lebensstil den Gesundheitszustand weiter verschlechtert und sich für die Betroffenen daraus ein erhöhtes Risiko für weitere chronische Erkrankungen ergibt. Bisherige Studienergebnisse beschreiben weder das Aktivitätsverhalten von Menschen mit erworbener Hirnschädigung noch wurden geeignete Interventionen zur nachhaltigen Steigerung der körperlichen Aktivität (KA) entwickelt. Ziel der vorliegenden Arbeit war es ein umfassendes Abbild des Aktivitätsverhaltens im Alltag von Menschen mit erworbener Hirnschädigung zu erstellen sowie die Machbarkeit und die Auswirkungen einer Bewegungsintervention auf das Aktivitätsverhalten und die Lebensqualität zu untersuchen.
In silico Epitope Mapping of Glucose-6-Phosphate Isomerase: A Rheumatoid Arthritis Autoantigen
(2017)
Rheumatoid arthritis-like symptoms can be initiated experimentally in naive K/BxN mice by simultaneously administering the two monoclonal antibodies 11H3 and 46H9. Both antibodies specifically recognize Glucose-6-Phosphate Isomerase (GPI), a known auto antigen in RA patients. Amino acid sequences of the Fv parts of the antibodies were determined by translating the respective hybridoma DNA sequences and served for threedimensional structure modeling of the paratope regions. In silico docking of both Fv antibody structure models to the X-ray structures of the homodimeric murine GPI as well as to the homodimeric human GPI predicted the murine epitope of the 11H3 antibodies to comprise partial amino acid sequences QRVRSGDWKGYTGKS (aa134-148) and AAKDPSAVAK (aa232-241), generating an assembled (conformational) epitope. The 11H3 epitope on human GPI encompasses the matching partial amino acid sequences QRVRSGDWKGYTGKT (aa134-148) and AAKDPSAVAK (aa232-241). The epitope of the 46H9 antibody was determined to consist of the partial murine GPI amino acid sequence RKELQAAGKSPEDLEK (aa446-461) and the human GPI amino acid sequence RKELQAAGKSPEDLER (aa446-461), respectively, resembling consecutive (linear) epitopes. The predicted epitopes were verified by mass spectrometric epitope mapping using synthetic epitope peptides. Peptide QRVRSGDWKGYTGKS[GSMSGS] AAKDPSAAK included a small spacer sequence in between the epitope sequences, mimicking the assembled epitope for the 11H3 antibody. The peptide RKELQAAGKSPEDLEK represented the consecutive epitope for the 46H9 antibody. The determined B-cell epitopes of GPI and their interactions with the monoclonal antibodies provide a detailed structural understanding of immunological disease onset mechanisms in a mouse model of rheumatoid arthritis.
This paper presents the b-it-bots RoboCup@Work team and its current hardware and functional architecture for the KUKA youBot robot.
