The µISEs are incorporated into a specially designed measuring system for the simultaneous detection of heavy metals and cyanide in solutions and validated by simultaneous measurements of Cu2+- and CN--ions, Cd2+- and CN-- ions and Pb2+- and CN--ions.

Full optimization of biosensing performance, however, is only reached if the film morphology is suitable for the principle of detection of a specific biosensor. In this paper, we report a detailed morphology analysis of LbL films made with alternating layers of single-walled carbon nanotubes (SWNTs) and polyamidoamine (PAMAM) dendrimers, which were then covered with a layer of penicillinase (PEN). An optimized performance to detect penicillin G was obtained with 6-bilayer SWNT/PAMAM LbL films deposited on p-Si-SiO2-Ta2O5 chips, used in biosensors based on a capacitive electrolyte-insulator-semiconductor (EIS) and a light-addressable potentiometric sensor (LAPS) structure, respectively. Field-emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) images indicated that the LbL films were porous, with a large surface area due to interconnection of SWNT into PAMAM layers. This morphology was instrumental for the adsorption of a larger quantity of PEN, with the resulting LbL film being highly stable. The experiments to detect penicillin were performed with constant-capacitance (ConCap) and constant-current (CC) measurements for EIS and LAPS sensors, respectively, which revealed an enhanced detection signal and sensitivity of ca. 100 mV/decade for the field-effect sensors modified with the PAMAM/SWNT LbL film. It is concluded that controlling film morphology is essential for an enhanced performance of biosensors, not only in terms of sensitivity but also stability and response time.}, language = {en} } @article{BehbahaniTranWalugaetal.2009, author = {Behbahani, Mehdi and Tran, L. and Waluga, C. and Behr, Marek and Oedekoven, B. and Mottaghy, K.}, title = {Model-based Numerical Analysis of Platelet Adhesion, Thrombus Growth and Aggregation for Assist Devices}, series = {The International Journal of Artificial Organs. 32 (2009), H. 7}, journal = {The International Journal of Artificial Organs. 32 (2009), H. 7}, isbn = {0391-3988}, pages = {398 -- 398}, year = {2009}, language = {en} } @article{SchoeningSchaubZundeletal.1995, author = {Sch{\"o}ning, Michael Josef and Schaub, A. and Zundel, A. and Beckers, Leah and Schubert, J. and Zander, W. and Kordos, P. and L{\"u}th, H.}, title = {Pulsed laser deposition as a novel thin film preparation method for silicon-based field effect sensors}, series = {Proceedings of the 25th European Solid State Device Research Conference : the Netherlands Congress Centre, The Hague, the Netherlands, 25th - 27th September 1995 / ESSDERC '95.

For this purpose, a dedicated model is developed. It is calibrated on published results of brake tests and validated against a high-definition model for low-speed applications. Based on this model, multiple simulations are executed to obtain a Monte Carlo simulation of the resulting braking distances. Based on the distribution properties and established safety levels, the risk of exceeding certain braking distances is evaluated and maximum braking distances are derived.

The concept is based upon a minimally invasive melting probe called the IceMole. The force-regulated, heater-controlled IceMole is able to travel along a curved trajectory as well as upwards. Hence, it allows maneuvers which may be necessary for obstacle avoidance or target selection.

Transmitted and elastic scattering intensity of the microspheres (radius 500 μm, refractive index 1.77) on an optical fiber half coupler is analyzed at 1510 nm. The 0.43 nm angular mode spacing of the resonances is comparable to the angular mode spacing value estimated using the optical size of the microsphere. The spectral linewidths of the resonances are in the order of 0.01 nm, which corresponds to quality factors of approximately 105. A polydopamine layer is used as a functionalizing agent on sapphire microspherical resonators in view of biosensor implementation. The varying layer thickness on the microsphere is determined as a function of the resonance wavelength shift. It is shown that polymer functionalization has a minor effect on the quality factor.

Attempts to efficiently express the enzyme in common expression hosts had failed. This study reports on the realization of overexpression in Escherichia coli after structural modification of HP70. Modelling of HP70 resulted in a two-domain structure, comprising the catalytic domain and a C-terminal domain which includes about 100 amino acids. On the basis of the modelled structure the enzyme was truncated by deletion of most of the C-terminal domain yielding HP70-C477. This structural modification allowed effective expression of active enzyme using E. coli BL21-Gold as the host. Specific activity of HP70-C477 determined with suc-l-Ala-l-Ala-l-Pro-l-Phe-p-nitroanilide as the substrate was 30 ± 5 U/mg compared to 8 ± 1 U/mg of the native enzyme. HP70-C477 was most active at 40 °C and pH 7-11; these conditions are prerequisite for a potential application as detergent enzyme. Determination of kinetic parameters at 40 °C and pH = 9.5 resulted in KM = 0.23 ± 0.01 mM and kcat = 167.5 ± 3.6 s⁻¹. MS-analysis of peptide fragments obtained from incubation of HP70 and HP70-C477 with insulin B indicated that the C-terminal domain influences the cleavage preferences of the enzyme. Washing experiments confirmed the high potential of HP70-C477 as detergent protease.}, language = {en} } @article{RibitschHeumannTrotschaetal.2011, author = {Ribitsch, Doris and Heumann, Sonja and Trotscha, Eva and Herrero Acero, Enrique and Greimel, Katrin and Leber, Regina and Birner-Gruenberger, Ruth and Deller, Sigrid and Eiteljoerg, Inge and Remler, Peter and Weber, Thomas and Siegert, Petra and Maurer, Karl-Heinz and Donelli, Ilaria and Freddi, Giuliano and Schwab, Helmut and Guebitz, Georg M.}, title = {Hydrolysis of polyethyleneterephthalate by p-nitrobenzylesterase from Bacillus subtilis}, series = {Biotechnology progress}, volume = {Vol. 27}, journal = {Biotechnology progress}, number = {Iss. 4}, publisher = {Wiley}, address = {Hoboken}, issn = {1520-6033 (E-Journal); 8756-7938 (Print)}, pages = {951 -- 960}, year = {2011}, language = {en} } @article{SchaeferHoefkenSchuba2011, author = {Schaefer, Thomas and H{\"o}fken, Hans-Wilhelm and Schuba, Marko}, title = {Windows Phone 7 from a Digital Forensics' Perspective}, publisher = {Springer}, address = {Berlin}, doi = {10.1007/978-3-642-35515-8_6}, year = {2011}, language = {en} } @article{SchubaReichlKesdoganetal.1998, author = {Schuba, Marko and Reichl, Peter and Kesdogan, Dogan and Jungh{\"a}rtchen, Klaus}, title = {Simulative Performance Evaluation of the Temporary Pseudonym Method for Protecting Location Information in GSM Networks / Reichl, P. ; Kesdogan, D. ; Jungh{\"a}rtchen, K. ; Schuba, M.}, series = {Computer Performance Evaluation - Modelling Techniques and Tools / Puigjaner, Ramon (eds.)}, journal = {Computer Performance Evaluation - Modelling Techniques and Tools / Puigjaner, Ramon (eds.)}, publisher = {Springer}, address = {Berlin}, isbn = {3-540-64949-2}, pages = {105 -- 116}, year = {1998}, language = {en} } @article{SchubaHaverkortSchneider2000, author = {Schuba, Marko and Haverkort, Boudewijn R. and Schneider, Gaby}, title = {Performance evaluation of multicast communication in packet-switched networks / Schuba, Marko ; Haverkort, Boudewijn R. ; Schneider, Gaby}, series = {Performance Evaluation. 39 (2000), H. 1-4}, journal = {Performance Evaluation. 39 (2000), H. 1-4}, isbn = {0166-5316}, doi = {10.1016/S0166-5316(99)00058-9}, pages = {61 -- 80}, year = {2000}, language = {en} } @article{SchubaHermanns1995, author = {Schuba, Marko and Hermanns, Oliver}, title = {Performance Investigations of the IP Multicast Architecture / Hermanns, Oliver ; Schuba, Marko}, series = {Performance of the IP Multicast Achitecture .

Consequently, within the coal industry, there is a growing recognition of the potential of microbial applications in fostering innovative technologies. Microbial-based coal solubilization, coal beneficiation, and coal dust suppression are green alternatives to traditional thermochemical and leaching technologies and better meet the need for ecologically sound and economically viable choices. Surfactant-mediated approaches have emerged as powerful tools for modeling, simulation, and optimization of coal-microbial systems and continue to gain prominence in clean coal fuel production, particularly in microbiological co-processing, conversion, and beneficiation. Surfactants (surface-active agents) are amphiphilic compounds that can reduce surface tension and enhance the solubility of hydrophobic molecules. A wide range of surfactant properties can be achieved by either directly influencing microbial growth factors, stimulants, and substrates or indirectly serving as frothers, collectors, and modifiers in the processing and utilization of coal. This review highlights the significant biotechnological potential of surfactants by providing a thorough overview of their involvement in coal biodegradation, bioprocessing, and biobeneficiation, acknowledging their importance as crucial steps in coal consumption.}, language = {en} } @article{FreyerKemptKloeser2024, author = {Freyer, Nils and Kempt, Hendrik and Kl{\"o}ser, Lars}, title = {Easy-read and large language models: on the ethical dimensions of LLM-based text simplification}, series = {Ethics and Information Technology}, volume = {26}, journal = {Ethics and Information Technology}, publisher = {Springer}, address = {Dortrecht}, issn = {1388-1957 (Print)}, doi = {10.1007/s10676-024-09792-4}, pages = {10 Seiten}, year = {2024}, abstract = {The production of easy-read and plain language is a challenging task, requiring well-educated experts to write context-dependent simplifications of texts.

Thus, even though there is a tendency to broaden the domain of easy-read and plain language, the inaccessibility of a significant amount of textual information excludes the target audience from partaking or entertainment and restricts their ability to live life autonomously. Large language models can solve a vast variety of natural language tasks, including the simplification of standard language texts to easy-read or plain language. Moreover, with the rise of generative models like GPT, easy-read and plain language may be applicable to all kinds of natural language texts, making formerly inaccessible information accessible to marginalized groups like, a.o., non-native speakers, and people with mental disabilities.

The fusion welding of SLM components made of 316L has so far been rarely investigated and if so, then for highly specialised laser welding processes. When welding with industrial gas welding processes such as MIG/MAG or TIG welding, distortions occur which are associated with the resulting residual stresses in the components. This paper investigates process-side influencing factors to avoid resulting residual stresses in SLM components made of 316L. The aim is to develop a strategy to build up SLM components as stress-free as possible in order to join them as profitably as possible with a downstream welding process. For this purpose, influencing parameters such as laser power, scan speed, but also scan vector length and different scan patterns are investigated with regard to their influence on residual stresses.}, language = {en} } @article{AbbasBalcBremenetal.2024, author = {Abbas, Karim and Balc, Nicolae and Bremen, Sebastian and Hedwig, Lukas}, title = {Polyetheretherketone (PEEK) in rapid tooling: advancements and applications for fused filament fabrication of rubber molds}, series = {Acta Technica Napocensis}, volume = {67}, journal = {Acta Technica Napocensis}, number = {1s}, publisher = {Technical University of Cluj-Napoca}, address = {Cluj-Napoca}, issn = {1221-5872}, pages = {13 -- 22}, year = {2024}, abstract = {Establishing high-performance polymers in additive manufacturing opens up new industrial applications.

The underlying technologies like cyber-physical systems (CPS), big data, collaborative robotics, additive manufacturing or artificial intelligence offer huge potentials for the optimization and evolution of production systems. However, many manufacturing companies struggle to implement these technologies. This can only in part be attributed to the lack of skilled personal within these companies or a missing digitalization strategy. Rather, there is a fundamental incompatibility between the way current production systems and companies (Industry 3.0) are structured across multiple dimensions compared to what is necessary for industry 4.0. This is especially true in manufacturing systems and their transition towards flexible, decentralized and autonomous value creation networks.

However, accurate and reliable parking slot detection (PSD) remains a challenge, especially in the low-light conditions typical of indoor car parks. Existing camera-based approaches struggle with these conditions and require sensor fusion to determine parking slot occupancy. This paper proposes a parking slot detection (PSD) algorithm which utilizes the intensity of a LiDAR point cloud to detect the markings of perpendicular parking slots. LiDAR-based approaches offer robustness in low-light environments and can directly determine occupancy status using 3D information. The proposed PSD algorithm first segments the ground plane from the LiDAR point cloud and detects the main axis along the driving direction using a random sample consensus algorithm (RANSAC). The remaining ground point cloud is filtered by a dynamic Otsu's threshold, and the markings of parking slots are detected in multiple windows along the driving direction separately. Hypotheses of parking slots are generated between the markings, which are cross-checked with a non-ground point cloud to determine the occupancy status. Test results showed that the proposed algorithm is robust in detecting perpendicular parking slots in well-marked car parks with high precision, low width error, and low variance. The proposed algorithm is designed in such a way that future adoption for parallel parking slots and combination with free-space-based detection approaches is possible. This solution addresses the limitations of camera-based systems and enhances PSD accuracy and reliability in challenging lighting conditions.}, language = {en} } @article{BoehnischBraunMarzoccaetal.2024, author = {B{\"o}hnisch, Nils and Braun, Carsten and Marzocca, Pierre and Muscarello, Vincenzo}, title = {Impact of aerodynamic interactions on aeroelastic stability of wing-propeller systems}, series = {Applied Sciences}, volume = {14}, journal = {Applied Sciences}, number = {19}, publisher = {MDPI}, address = {Basel}, issn = {2076-3417}, doi = {10.3390/app14198709}, year = {2024}, abstract = {This paper presents initial findings from aeroelastic studies conducted on a wing-propeller model, aimed at evaluating the impact of aerodynamic interactions on wing flutter mechanisms and overall aeroelastic performance. The flutter onset is assessed using a frequency-domain method. Mid-fidelity tools based on the time-domain approach are then exploited to account for the complex aerodynamic interaction between the propeller and the wing. Specifically, the open-source software DUST and MBDyn are leveraged for this purpose. The investigation covers both windmilling and thrusting conditions. During the trim process, adjustments to the collective pitch of the blades are made to ensure consistency across operational points. Time histories are then analyzed to pinpoint flutter onset, and corresponding frequencies and damping ratios are identified. The results reveal a marginal destabilizing effect of aerodynamic interaction on flutter speed, approximately 5\%. Notably, the thrusting condition demonstrates a greater destabilizing influence compared to the windmilling case. These comprehensive findings enhance the understanding of the aerodynamic behavior of such systems and offer valuable insights for early design predictions and the development of streamlined models for future endeavors.}, language = {en} } @article{HueningHeuermannWache2018, author = {H{\"u}ning, Felix and Heuermann, Holger and Wache, Franz-Josef}, title = {Wireless CAN without WLAN or Bluetooth}, series = {CAN Newsletter}, journal = {CAN Newsletter}, number = {December}, publisher = {CAN in Automation GmbH}, address = {N{\"u}rnberg}, pages = {44 -- 46}, year = {2018}, abstract = {In two developed concepts, dual-mode radio enables CAN participants to be integrated wirelessly into a CAN network.
