Taschenbuch. Condition: Neu. Neuware -Scope of this work is to determine cycle time formulas for packing in distribution centres. No such formulas exist today, even if it is the second most important process after picking. Based on examining packing, morphological boxes showing time influencing parameters are derived. The most significant parameters are identified using analysis of variance (ANOVA). Cycle times are determined and applied to cases. These prove that the formulas can be used to calculate the time required for packing.Books on Demand GmbH, Überseering 33, 22297 Hamburg 190 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Parallel transmission enables control of the RF field in high-field Magnetic Resonance Imaging (MRI). However, the approach has also caused concerns about the specific absorption rate (SAR) in the patient body. The present work provides new concepts for SAR prediction. A novel approach for generating human body models is proposed, based on a water-fat separated MRI pre-scan. Furthermore, this work explores various approaches for SAR reduction.Books on Demand GmbH, Überseering 33, 22297 Hamburg 142 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Superconducting Nanowire Single-Photon Detectors offer the capability to detect electromagnetic waves on a single photon level in a wavelength range that far exceeds that of alternative detector types. However, above a certain threshold wavelength, the efficiency of those detectors decreases stronlgy, leading to a poor performance in the far-infrared range. Influences on this threshold are studied and approaches for improvement are verified experimentally by measurement of the device performance.Books on Demand GmbH, Überseering 33, 22297 Hamburg 200 pp. Englisch.
