Constructing Obstacles: Welchen Einfluss haben Verkehrsabsicherungen an Arbeitsstellen auf die (wahrgenommene) Sicherheit von Radfahrenden?
(2023)
Durch die an Arbeitsstellen verminderte Flächenverfügbarkeit zur Leitung des Verkehrs entstehen in vielen Situationen, an denen im Straßenverkehr gebaut wird, zwangsläufig Konfliktsituationen. Diese Forschung untersucht, welche Faktoren dazu beitragen, auch unter diesen Umständen die (wahrgenommene) Sicherheit dieser Verkehrsteilnehmenden zu wahren. Bisher wurden Arbeitsstellen in Hinblick auf Sicherheitskriterien für den aktiven Verkehr wenig untersucht, weshalb diese Forschung die Erkenntnisse für geteilte ...

Investigating the Safety Behaviour of Cyclists in Construction Sites
(2023)
In this study, we employ counting devices like those provided by Eco Counter GmbH as well as a camera system to systematically investigate the choices made by cyclists regarding their path choice. It is also investigated how reliable these devices count the choices cyclists make, such as using the sidewalk or shared lanes. Together the results provide valuable insights into the factors influencing cyclists’ path preferences.

Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
(Society of Plastics Engineers, 2016)
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is ...

Utilizing Continuous Kernels for Processing Irregularly and Inconsistently Sampled Data With Position-Dependent Features
(2023-03-13)
Continuous Kernels have been a recent development in convolutional neural networks. Such kernels are used to process data sampled at different resolutions as well as irregularly and inconsistently sampled data. Convolutional neural networks have the property of translational invariance (e.g., features are detected regardless of their position in the measurement domain), which is unsuitable for certain types of data, where the position of detected features is relevant. However, the capabilities of continuous kernels ...

On the Challenges toward Realization of Functionally Graded Structures by Electron Beam Melting—Fe-Base Shape Memory Alloy and Stainless Steel
(ASTM International, 2020-09-22)
In the present study, an iron-manganese-aluminum-nickel (Fe-Mn-Al-Ni) shape memory alloy was processed on an austenitic steel (AISI 304) build platform by electron beam melting in order to study the feasibility of realizing functionally graded structures consisting of two different materials (i.e., a functional and a structural material). Compression specimens consisting of the processed shape memory alloy and the austenitic build platform in equal parts were investigated. The microstructure was analyzed in the ...

Fast parallel quasi-static time series simulator for active distribution grid operation with pandapower
(IET, 2021)
The increasing penetration from intermittent renewable distributed energy resources in distribution grid brings along challenges in grid operation and planning. To evaluate the impact on the grid voltage profile, grid losses, and discrete actions from assets (e.g. transformer tap changes), quasi-static simulation is an appropriate method. Quasi-static time series and Monte-Carlo simulation requires a tremendous number of power flow calculations (PFCs), which can be significantly accelerated with a parallel High-Performance ...

Influence Of The Fiber-Matrix-Interaction On The Fracture Behavior Of Regenerated Cellulose Fiber Reinforced Polypropylene
(Society of Plastics Engineers, 2017)
This investigation focuses on the fiber-matrix-interaction of man-made cellulose fibers (RCF) in a PP matrix with an additional MAPP content using an energetic evaluation of the single fiber pull-out test (SFPT). Furthermore glass fibers were characterized for reference purposes. With the SFPT the interfacial shear strength (IFFS) and the critical fiber length (lc) as well as the consumed energy of a fiber pull-out and a fiber rupture were determined. In a following step the resulting values of lc were related to the ...

Blending CA with PBS to increase the bonding strength in two-component injection molding
(Society of Plastics Engineers, 2019)
Since CA shows no adhesive properties in the two-component injection molding process with bio based TPU, blends of CA and PBS were produced to decrease the interfacial tension between the materials. While the interfacial tension was calculated from the results of a drop shape analysis, the adhesion strength was measured in peel tests according to the guideline VDI 2019. The comparison of the results gave information about whether the drop shape analysis is a valid method to analyze the adhesive characteristics of ...
