Throughput Analysis of Manual Order Picking Systems with Congestion Consideration
(2011)
Throughput in manual order picking systems with narrow aisles suffers from congestion as pickers cannot pass each other. Only few models incorporate congestion but they have very strict assumptions. In this work, queueing ...
Synthese kapazitätsoptimierter Antennensysteme mit messtechnischer Verifikation
(2018)
This work describes an optimization concept for mobile antenna systems. The so-called antenna synthesis determines optimal fixed antenna radiation patterns with the help of simulated or measured transmission channels. These ...
Systematic Study of Key Components for a Coaxial-Cavity Gyrotron for DEMO
(2017)
The physical design of cavity and magnetron injection gun (MIG) for a realistic, DEMO-compatible, coaxial-cavity 238 GHz 2 MW CW fusion gyrotron is developed in this work, having auxiliary frequencies at 170 GHz and 204 ...
Systemansatz zur anregungsunabhängigen Charakterisierung des Schwingungskomforts eines Fahrzeugs
(2011)
Im Rahmen der Arbeit wird ein Systemansatz entwickelt, der den Schwingungskomfort eines Fahrzeugs unabhängig von der Fahrbahnanregung durch sechs Parameter charakterisiert. Hierfür werden zur Berücksichtigung der nichtlinearen ...
Subspace-Identification zur Modellierung von PEM-Brennstoffzellen-Stacks
(2010)
Der theoretische Schwerpunkt dieser Arbeit liegt in einem Vergleich und einer einheitlichen Beschreibung der in der Literatur existierenden Subspace-Identification-Verfahren. Im Anwendungsteil kommen diese zum Einsatz, um ...
Suitability of local materials to purify Akaki Sub-Basin water
(2007)
Dissolved and suspended particulate matter (SPM) bound Cu, Zn, Ni, As, Pb, Mn, and Fe are common pollutants in surface and groundwater of the Akaki Sub-Basin.This work (1) presents results of water quality analysis and (2) ...
Sulfur-tolerant natural gas reforming for fuel-cell applications
(2010)
An attractive simplification of PEM-FC systems operated with natural gas would be the use of a sulfur tolerant reforming catalyst, but such a catalyst has not been available thus far. In this work it is demonstrated that ...
Stoffgesetz zur Beschreibung des Kriech- und Relaxationsverhaltens junger normal- und hochfester Betone
(2013)
Within this work a material law was developed which correctly describes the creep and relaxation characteristics of young and mature normal strength and high-strength concretes. It is based on an aging thermodynamically ...
Stochastische Simulation von Energieflüssen im NutzfahrzeugEin einsatzorientiertes Bewertungs- und Optimierungsverfahren
(2015)
This book proposes a stochastic simulation process as an efficient approach to consumption simulation. The process complements the explicit transient analysis. Thereby, it takes into account statistically evaluated vehicle ...
Stochastische Simulation großflächiger, hochwasserrelevanter Niederschlagsereignisse
(2018)
The risk estimation of precipitation events with high recurrence periods is difficult due to the limited time scale with meteorological observations. A homogenous distribution of rain gauges, especially in mountainous ...
