Design of an experiment to investigate superheat effect on gate velocities
… on gate velocities pressurized and unpressurized gating system each having two gates, and to analyze statistically any interrelationship between these variables in CO₂ molds. A discussion on metal flow through different parts of a gating system, with a minimum of turbulence and gas aspiration, and …

Studies of pig social groupings
… effectiveness of a computer-controlled feeding system for dynamically group-housed gestating gilts. Of particular interest was the behavior of gilts housed in large dynamic groups and its influence on their well-being as compared to the well-being of gilts housed in standard gestation stalls. …

A noise-gated PLL for clock recovery in a free-space laser communication system
In this thesis, I developed a phase-locked loop system for data clock recovery in a free-space laser communication application. The clock recovery unit is designed to operate at extremely low optical received power, tolerate a fading channel, and also account for Doppler effects. I explored the …

Development, characterization, and application of a charged particle microbeam for radiobiological research
… explore the radiation response of biological systems on a cellular and subcellular level, particularly in the area of temporal and spatial effects of radiation on in vitro systems. An accelerator-based 750 keV proton source was characterized and integrated into a laboratory-scale device that …

Behaviours of bifilms in A356 alloy during solidification: developing observation techniques with 3-D micro x-ray tomography
… bars, an oxide generator was designed using a gating system. Micro X-ray tomography (Skyscan 1702) was used to establish the best specimen diameter and scanning conditions, including exposure time, magnification, rotation angle and rotation-step angle. Following scanning, the specimens were …

Optimierung des Kokillengießverfahrens auf Schutzgasanwendungen
… of the for inert gas casting dedicated gating system. The preset criteria were fulfilled after six development stages, wherewith the conditions for the start of the actual test matrix have been cleared. The basis of valuation of the casting trials was represented by the results of a dye …

Femtosecond optical parametric oscillators for the mid-infrared
… autocorrelation and frequency-resolved optical gating techniques. A highly advantageous autocorrelator arrangement based on quadratic nonlinearity in light-emitting diodes and photodiodes was demonstrated, and a novel second harmonic generation frequency-resolved optical gating system allowed …

Data-driven depth and 3D architectural layout estimation of an interior environment from monocular panoramic input
… efficient single-branch network with a dynamic gating system, processing both dense visual data and sparse geometric data. Additionally, a new augmentation strategy enhances the model's robustness to various types of sparsity, including those from structured light sensors and LiDAR setups. While …

Rekonstruktion bronzezeitlicher Gießereitechniken mittels numerischer Simulation, gießtechnologischer Experimente und werkstofftechnischer Untersuchungen an Nachguss und Original
… experiments. Thus, until now there are only few systematic and technically reliable studies within this field. At this point, in contrast to other prehistoric periods, our knowledge about the Bronze Age takes advantage of a big amount of preserved, mainly casted metal artefacts. This circumstance …
