Spaltversagen von Holz in Verbindungen - Ein Rechenmodell für die Rissbildung beim Eindrehen von Holzschrauben
(2009)
In dieser Arbeit wurde ein Rechenmodell entwickelt, mit dem die Rissbildung im Holz beim Eindrehen von Schrauben erfasst werden kann. Es ermöglicht die Abschätzung der erforderlichen Mindestholzdicken und Mindestabstände ...
Spaltverhalten von Holz beim Eindrehen von selbstbohrenden Holzschrauben
(2012)
Für Verbindungen im Holzbau werden häufig selbstbohrende Holzschrauben eingesetzt. Diese können oft mit geringen Abständen untereinander und zu den Bauteilrändern angeordnet werden. Durch die Einhaltung von Mindestabständen ...
Special issue: Customer empowerment
(2014)
The second French-German workshop about Consumer Empowerment took place at the University of Karlsruhe (KIT) between January 10-11, 2013. Within the scope of consumer empowerment scientists discussed recent developments ...
Specification and verification of object-oriented software components
(2006)
This work presents a flexible methodology for formally specifying and deductively verifying object-oriented components.It is based on a simple notion of program correctness. Correctness can be achieved with a novel system ...
Spectroscopic ellipsometry of interfacial phase transitions in fluid metallic systems: KxKCl1-x and Ga1-xBix [online]
(2004)
The investigation of the interfacial phase transitions in fluid systems with short-range intermetallic interactions are of great interest. The phenomena were studied in two systems exhibiting a liquid-liquid miscibility ...
Spectroscopic investigations of delaminated and intercalated phyllosilicates
(2005)
The characteristic feature of phyllosilicates like muscovite (KAl2[Si3AlO10(OH)2] is their layered structure. Due to the resulting anisotropic optical and electrical properties this mineral is an important raw material in ...
Spectral near field data of LED systems for optical simulations
(2018)
This book presents, validates and applies a fast, accurate and general measurement and modeling technique to obtain spectral near field data of LED systems for optical simulations in order to address the steadily increasing ...
Thermische Alterung von Dieseloxidationskatalysatoren und NOx-Speicherkatalysatoren: Korrelierung von Aktivität und Speicherfähigkeit mit physikalischen und chemischen Katalysatoreigenschaften
(2013)
Increasing demands on emission limitations caused by legislative directives call for numerical simulation to support the development of automotive exhaust gas aftertreatment systems. Since the efficiency in pollution ...
Thermische Charakterisierung von keramischen Schwammstrukturen für verfahrenstechnische Apparate
(2011)
In dieser Arbeit wurden Schwämme aus Al2O3, Mullit und oxidisch gebundenem SiC hinsichtlich ihrer Impuls- und Wärmetransporteigenschaften experimentell untersucht. Zur Auslegung chemischer Apparate nach dem heterogenen ...
Thermochemistry and Kinetics for the Oxidative Degradation of Dibenzofuran and Precursors
(2006)
The emission of dibenzofurans and dioxins from industrial processes is a major environmental concern. Focussing on dibenzofuran, this study tend to improve our understanding of the general oxidation chemistry and to provide ...
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 ...

(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 ...
