At the same time the awareness and knowledge about cybersecurity, particularly in the context of ICS, is alarmingly low. Industrial honeypots offer a cheap and easy to implement way to raise cybersecurity awareness and to educate ICS staff about typical attack patterns. When integrated in a productive network, industrial honeypots may not only reveal attackers early but may also distract them from the actual important systems of the network. Implementing multiple honeypots as a honeynet, the systems can be used to emulate or simulate a whole Industrial Control System. This paper describes a network of honeypots emulating HTTP, SNMP, S7communication and the Modbus protocol using Conpot, IMUNES and SNAP7. The nodes mimic SIMATIC S7 programmable logic controllers (PLCs) which are widely used across the globe. The deployed honeypots' features will be compared with the features of real SIMATIC S7 PLCs. Furthermore, the honeynet has been made publicly available for ten days and occurring cyberattacks have been analyzed}, language = {en} } @incollection{SchubaHoefken2022, author = {Schuba, Marko and H{\"o}fken, Hans-Wilhelm}, title = {Cybersicherheit in Produktion, Automotive und intelligenten Geb{\"a}uden}, series = {IT-Sicherheit - Technologien und Best Practices f{\"u}r die Umsetzung im Unternehmen}, booktitle = {IT-Sicherheit - Technologien und Best Practices f{\"u}r die Umsetzung im Unternehmen}, publisher = {Carl Hanser Verlag}, address = {M{\"u}nchen}, isbn = {978-3-446-47223-5}, doi = {10.3139/9783446473478.012}, pages = {193 -- 218}, year = {2022}, language = {de} } @article{SchubaHoefken2012, author = {Schuba, Marko and H{\"o}fken, Hans}, title = {Backtrack5: Datensammlung und Reporterstellung f{\"u}r Pentester mit MagicTree / H{\"o}fken, Hans ; Schuba, Marko}, series = {Hakin9. 73 (2012), H. 3}, journal = {Hakin9. 73 (2012), H. 3}, publisher = {-}, isbn = {1733-7186}, pages = {12 -- 16}, year = {2012}, language = {de} } @article{SchubaHoefkenSchaefer2012, author = {Schuba, Marko and H{\"o}fken, H. and Schaefer, T.}, title = {Smartphone Forensik}, series = {Hakin9 : Practical Protection (2012)}, journal = {Hakin9 : Practical Protection (2012)}, publisher = {-}, isbn = {1733-7186}, pages = {10 -- 20}, year = {2012}, language = {de} } @article{SchubaHermanns1994, author = {Schuba, Marko and Hermanns, Oliver}, title = {Modellierung von Multicastmechanismen zur Unterst{\"u}tzung von Gruppenkommunikation / Schuba, Marko ; Hermanns, Oliver}, series = {Neue Konzepte f{\"u}r die offene verteilte Verarbeitung : Tagungsband des 1.

Both in its varied natural habitats and in industrial settings, B. licheniformis cells will be exposed to increases in the external osmolarity, conditions that trigger water efflux, impair turgor, cause the cessation of growth, and negatively affect the productivity of cell factories in biotechnological processes. We have taken here both systems-wide and targeted physiological approaches to unravel the core of the osmostress responses of B. licheniformis. Cells were suddenly subjected to an osmotic upshift of considerable magnitude (with 1 M NaCl), and their transcriptional profile was then recorded in a time-resolved fashion on a genome-wide scale. A bioinformatics cluster analysis was used to group the osmotically up-regulated genes into categories that are functionally associated with the synthesis and import of osmostress-relieving compounds (compatible solutes), the SigB-controlled general stress response, and genes whose functional annotation suggests that salt stress triggers secondary oxidative stress responses in B. licheniformis. The data set focusing on the transcriptional profile of B. licheniformis was enriched by proteomics aimed at identifying those proteins that were accumulated by the cells through increased biosynthesis in response to osmotic stress. Furthermore, these global approaches were augmented by a set of experiments that addressed the synthesis of the compatible solutes proline and glycine betaine and assessed the growth-enhancing effects of various osmoprotectants. Combined, our data provide a blueprint of the cellular adjustment processes of B. licheniformis to both sudden and sustained osmotic stress.}, language = {en} } @masterthesis{Schrey2021, type = {Bachelor Thesis}, author = {Schrey, Leander}, title = {Less Waste Shelf: Ein M{\"o}bel zur Reduzierung der h{\"a}uslich anfallenden Lebensmittelabf{\"a}lle}, publisher = {FH Aachen}, address = {Aachen}, pages = {177 Seiten}, year = {2021}, abstract = {Mit dem Projekt wird sich dem Problem der weltweiten Lebensmittelverschwendung angenommen und versucht Abf{\"a}lle in Privathaushalten prim{\"a}r industrialisierter Staaten zu reduzieren.

By extending the idea of the Breakthrough Starshot project with a deceleration phase upon arrival, the mission's scientific yield will be increased. As a secondary objective, transfer trajectories between the stars and orbit-raising manoeuvres to explore the habitable zones of the stars are investigated. All trajectories are optimised for minimum time of flight using the trajectory optimisation software InTrance. Depending on the sail technology, interstellar travel times of 77.6-18,790 years can be achieved, which presents an average improvement of 30\% with respect to previous work. Still, significant technological development is required to reach and be captured in the Alpha-Centauri system in less than a century.

Measurements are conducted with a focus on a simple solution to decrease the processing time and reduce the integration time of the process into the existing hardware.

Results of the combined ignition and operation network from simulations and measurements are compared.

An innovative method through performing in situ electrochemical impedance spectroscopy is utilised to quantify the effect of inlet air relative humidity at the cathode side on internal ionic resistances and output voltage of the fuel cell. In addition, algorithms are developed to analyse the electrochemical characteristics of the fuel cell. For the specific fuel cell stack used in this study, the membrane resistance drops by over 39 \% and the cathode side charge transfer resistance decreases by 23 \% after increasing the humidity from 30 \% to 85 \%, while the results of static operation also show an increase of ∼2.2 \% in the voltage output after increasing the relative humidity from 30 \% to 85 \%. In dynamic operation, visible drying effects occur at < 50 \% relative humidity, whereby the increase of the air side stoichiometry increases the drying effects. Furthermore, other parameters, such as hydrogen humidification, internal stack structure, and operating parameters like stoichiometry, pressure, and temperature affect the overall water balance. Therefore, the optimal humidification range must be determined by considering all these parameters to maximise the fuel cell performance and durability.

Adsorption of the penicillinase and CNTs at dimyristoylphosphatidic acid (DMPA) monolayers at the air-water interface was investigated by surface pressure-area isotherms, vibrational spectroscopy, and Brewster angle microscopy. The floating monolayers were transferred to solid supports through the LB technique, forming mixed DMPA-CNTs-PEN films, which were investigated by quartz crystal microbalance, vibrational spectroscopy, and atomic force microscopy. Enzyme activity was studied with UV-vis spectroscopy and the feasibility of the supramolecular device nanostructured as ultrathin films were essayed in a capacitive electrolyte-insulator-semiconductor (EIS) sensor device. The presence of CNTs in the enzyme-lipid LB film not only tuned the catalytic activity of penicillinase but also helped conserve its enzyme activity after weeks, showing increased values of activity. Viability as penicillin sensor was demonstrated with capacitance/voltage and constant capacitance measurements, exhibiting regular and distinctive output signals over all concentrations used in this work. These results may be related not only to the nanostructured system provided by the film, but also to the synergism between the compounds on the active layer, leading to a surface morphology that allowed a fast analyte diffusion because of an adequate molecular accommodation, which also preserved the penicillinase activity. This work therefore demonstrates the feasibility of employing LB films composed of lipids, CNTs, and enzymes as EIS devices for biosensing applications.}, language = {en} } @article{SchoenrockMuckeltHastermannetal.2024, author = {Schoenrock, Britt and Muckelt, Paul E. and Hastermann, Maria and Albracht, Kirsten and MacGregor, Robert and Martin, David and Gunga, Hans-Christian and Salanova, Michele and Stokes, Maria J. and Warner, Martin B. and Blottner, Dieter}, title = {Muscle stiffness indicating mission crew health in space}, series = {Scientific Reports}, volume = {14}, journal = {Scientific Reports}, number = {Article number: 4196}, publisher = {Springer Nature}, address = {London}, issn = {2045-2322}, doi = {10.1038/s41598-024-54759-6}, pages = {13 Seiten}, year = {2024}, abstract = {Muscle function is compromised by gravitational unloading in space affecting overall musculoskeletal health. Astronauts perform daily exercise programmes to mitigate these effects but knowing which muscles to target would optimise effectiveness. Accurate inflight assessment to inform exercise programmes is critical due to lack of technologies suitable for spaceflight. Changes in mechanical properties indicate muscle health status and can be measured rapidly and non-invasively using novel technology. A hand-held MyotonPRO device enabled monitoring of muscle health for the first time in spaceflight (> 180 days). Greater/maintained stiffness indicated countermeasures were effective. Tissue stiffness was preserved in the majority of muscles (neck, shoulder, back, thigh) but Tibialis Anterior (foot lever muscle) stiffness decreased inflight vs. preflight (p < 0.0001; mean difference 149 N/m) in all 12 crewmembers. The calf muscles showed opposing effects, Gastrocnemius increasing in stiffness Soleus decreasing. Selective stiffness decrements indicate lack of preservation despite daily inflight countermeasures. This calls for more targeted exercises for lower leg muscles with vital roles as ankle joint stabilizers and in gait. Muscle stiffness is a digital biomarker for risk monitoring during future planetary explorations (Moon, Mars), for healthcare management in challenging environments or clinical disorders in people on Earth, to enable effective tailored exercise programmes.}, language = {en} } @inproceedings{SchoeneReisgenSchleseretal.2010, author = {Schoene, Jens and Reisgen, Uwe and Schleser, Markus and Jerabek, Jakub and Chudoba, Rostislav}, title = {Theoretical and experimental investigations on textile-reinforced concrete spalling behavior}, series = {8th International PhD Symposium in Civil Engineering : Lyngby, June 20-23, 2010 : proceedings}, booktitle = {8th International PhD Symposium in Civil Engineering : Lyngby, June 20-23, 2010 : proceedings}, editor = {Fisher, Gregor}, publisher = {Technical University of Denmark, Dept. of Civil Engineering}, address = {Lyngby}, organization = {PhD Symposium in Civil Engineering <8, 2010, Lyngby> ; International Federation for Structural Concrete}, isbn = {9788778773012}, pages = {383 -- 388}, year = {2010}, language = {en} } @inproceedings{SchoeneReisgenSchleseretal.2011, author = {Schoene, Jens and Reisgen, Uwe and Schleser, Markus and Jerabek, Jakub}, title = {Theoretische und experimentelle Untersuchung des spaltungsinduzierten Versagens von TRC Pr{\"u}fk{\"o}rpern}, series = {Textilbeton - Theorie und Praxis : Tagungsband zum 6.

Entz{\"u}ndungen des umgebenden Zahnfleisches z{\"a}hlen dabei zu den h{\"a}ufigsten Komplikationen nach einer Implantation. Diese Entz{\"u}ndungen entstehen haupts{\"a}chlich durch bakterielle Infektionen des Weichgewebes an der Implantations-Stelle. Die raue Oberfl{\"a}che tr{\"a}gt jedoch zu einer solchen Infektion bei. Da der Implantat-Kopf zum Teil aus dem Knochen herausragt, erfolgt beispielsweise beim Z{\"a}hneputzen eine Freilegung der Implantat-Oberfl{\"a}che. Die durch die Rauheit vergr{\"o}ßerte Oberfl{\"a}che bietet dabei ideale Voraussetzungen f{\"u}r eine Bakterienansiedlung. In der aktuellen Forschung steht die Entwicklung einer Oberfl{\"a}che im Vordergrund, die eine antibakterielle Funktionalisierung erzeugt. Diese verhindert die Bakterienansiedlung und wirkt einer Entz{\"u}ndung entgegen. Um die Beschichtung vor Verschleiß zu sch{\"u}tzen und ihre Lebensdauer der antibakteriellen Wirkung zu erh{\"o}hen, ist es m{\"o}glich die Oberfl{\"a}che mit einer Mikrostruktur zu versehen. Das Ziel der vorliegenden Arbeit ist die Identifikation geeigneter Mikrostrukturierungen, die der antibakteriellen Beschichtung einen optimalen Schutz vor Verschleiß bieten. Am Beispiel von Titan-Zahnimplantaten wird der Schutz der aufgetragenen Biohybridbeschichtung gegen abrasiven Verschleiß untersucht. Im Vorfeld wird eine Analyse der fertigungstechnischen M{\"o}glichkeiten mit Blick auf dentale Implantate und Mikrostrukturen durchgef{\"u}hrt, um das ein passendes Verfahren zu identifizieren. Die Analogiebauteile als Probenk{\"o}rper werden, mithilfe des zuvor ausgew{\"a}hlten Verfahrens, mit verschiedenen Mikrostrukturen versehen. Im Rahmen einer Versuchsdurchf{\"u}hrung, die die mechanische Belastung bei einem Zahnputzdurchgang imitiert, werden die verschiedenen Mikrostrukturen auf ihre Eignung f{\"u}r diese Anwendung {\"u}berpr{\"u}ft. Ein Vorversuch dient zur Identifizierung eines geeigneten Ankerpeptids, welches den bindenden Bestandteil der Biohybridbeschichtung darstellt. Aus drei zuvor ausgew{\"a}hlten Ankerpeptiden wird das mit der besten Adh{\"a}sionsf{\"a}higkeit herausgestellt. Im finalen Versuchsdurchlauf wird das Ankerpeptid auf die Oberfl{\"a}chen, die mit den Mikrostrukturen versehen sind, aufgetragen. Dabei ist das Ziel eine Mikrostruktur herauszustellen, die den h{\"o}chstm{\"o}glichen Schutz bietet. Durch eine Fluoreszenzpr{\"u}fung mithilfe eines Flourescence Plate Readers wird jede Kombination nach den Belastungsversuchen auf den Restanteil der Beschichtung {\"u}berpr{\"u}ft. Das Ergebnis stellt eine Mikrostruktur dar, die den bestm{\"o}glichen Schutz bietet. Dies ist erkennbar durch den h{\"o}chsten Anteil an Restbeschichtung. Eine Strukturierung mit sogenannten Micro-Grooves in Kombination mit dem MacHis-Ankerpeptid erzielte in der Analyse der Belastungssimulationen die besten Ergebnisse bez{\"u}glich des Schutzes der Beschichtung. Durch die Versuche best{\"a}tigte sich eine weitere Annahme. Die Strukturierung der Oberfl{\"a}che erzielt einen deutlich h{\"o}heren Schutz im Vergleich zu einer unstrukturierten Oberfl{\"a}che. Zudem hat sich herausgestellt, dass eine Beschichtung mit dem sogenannten PEO-Verfahren eine deutlich gr{\"o}ßere Adh{\"a}sion der Biohybridbeschichtung erzielt. Dies wird jedoch Thema weiterf{\"u}hrender Forschungen sein und kein Bestandteil der vorliegenden Arbeit.}, language = {de} } @inproceedings{SchnellFranzenGligorevic2010, author = {Schnell, Michael and Franzen, Nico and Gligorevic, Snjezana}, title = {L-DACS1 laboratory demonstrator development and compatibility measurement set-up}, series = {IEEE/AIAA 29th Digital Avionics Systems Conference (DASC) : 3 - 7 Oct. 2010, Salt Lake City, Utah}, booktitle = {IEEE/AIAA 29th Digital Avionics Systems Conference (DASC) : 3 - 7 Oct. 2010, Salt Lake City, Utah}, organization = {Institute of Electrical and Electronics Engineers}, isbn = {9781424466160 ; 9781424466184}, pages = {3E3-1 -- 3E3-11}, year = {2010}, language = {en} } @inproceedings{SchnellBrandesGligorevicetal.2008, author = {Schnell, Michael and Brandes, Sinja and Gligorevic, Snjezana and Walter, M. and Rihacek, Christoph and Sajatovic, Miodrag and Haindl, Bernhard}, title = {Interference mitigation for broadband L-DACS}, series = {27th IEEE/AIAA Digital Avionics Systems Conference : DASC 2008 : 26-30 Oct. 2008, St. Paul, Minn.}, booktitle = {27th IEEE/AIAA Digital Avionics Systems Conference : DASC 2008 : 26-30 Oct. 2008, St. Paul, Minn.}, organization = {Institute of Electrical and Electronics Engineers}, isbn = {978-1-4244-2207-4 ; 978-1-4244-2208-1}, pages = {2B2-1 -- 2B2-12}, year = {2008}, language = {en} } @inproceedings{SchnejiderWisselinkCzarnecki2017, author = {Schnejider, Dominik and Wisselink, Frank and Czarnecki, Christian}, title = {Transformation von Wertsch{\"o}pfungsketten durch das Internet der Dinge - Bewertungsrahmen und Fallstudie}, series = {GI Edition Proceedings Band 275 INFORMATIK 2017}, booktitle = {GI Edition Proceedings Band 275 INFORMATIK 2017}, editor = {Eibl, Maximilian and Gaedke, Martin and Gesellschaft f{\"u}r Informatik e.
