This volume reports results from the German research initiative
MUNA (Management and Minimization of Errors and Uncertainties in
Numerical Aerodynamics), which combined development activities of
the German Aerospace Center (DLR), German universities and German
aircraft industry. The main objective of this five year project was
the development of methods and procedures aiming at reducing
various types of uncertainties that are typical of numerical flow
simulations. The activities were focused on methods for grid
manipulation, techniques for increasing the simulation accuracy,
sensors for turbulence modelling, methods for handling
uncertainties of the geometry and grid deformation as well as
stochastic methods for quantifying aleatoric uncertainties.

Over the last decade, Computational Fluid Dynamics (CFD) has become
a - ture technology for the development of new products in
aeronautical industry. Aerodynamic design engineers have
progressively taken advantage of the pos- bilities o?ered by the
numericalsolutionof the Reynolds averagedNavier-Stokes (RANS)
equations. Signi?cant improvements in physical modeling and
solution algorithms as well as the enormous increase of computer
power enable hi- ?delity numerical simulations in all stages of
aircraft development. In Germany, the national CFD project MEGAFLOW
furthered the dev- opment and availability of RANS solvers for the
prediction of complex ?ow problemssigni?cantly.
MEGAFLOWwasinitiated by the?rstaviationresearch

Kroll, N. , Fassbender, J. K. (Eds). : MEGAFLOW - Numerical Flow
Simulation for Aircraft Design; Notes on Numerical Fluid Mechanics
and Multidisciplinary Design, Volume 89, Springer, 2005). A network
from aircraft industry, DLR and several universities was created
with the goal to focus and direct development activities for
numerical ?ow simulation towards a common aerodynamic si- lation
system providing both a block-structured (FLOWer-Code) and a hybrid
(TAU-Code) parallel ? ow prediction capability. Today, both codes
have reached a high level of maturity and reliability. They are
routinely used at DLR and German aeronautic industry for a wide
range of aerodynamic applications. For many universities the
MEGAFLOW software represents a platform for the -

The network was established as an e?cient group of very closely
co-operating partners with supplementing expertises and experience.

Studienarbeit aus dem Jahr 2006 im Fachbereich BWL - Recht, Note:
1.7, AKAD-Fachhochschule Pinneberg, Sprache: Deutsch, Abstract:
Diese Hauptseminararbeit hatte zum Inhalt den normativen und
schuldrechtlichen Teil des Tarifvertrages zu beleuchten.
Tarifvertrage sind Kollektivvertrage, die eine spezifisch
arbeitsrechtliche Rechtsquelle bilden und fur den Inhalt des
Arbeitsverhaltnisses von grosster praktischer Bedeutung sind. Der
Tarifvertrag hat seine Rechtsgrundlage im TVG
(Tarifvertragsgesetz). So begrundet ein Tarifvertrag nicht nur
zwischen Tarifsvertragsparteien schuldrechtliche Beziehungen,
sondern setzt in seinem normativen Teil fur seinen Geltungsbereich
objektives Recht fur Inhalt, Abschluss oder Beendigung von
Arbeitsverhaltnissen. 2 TVG stellt klar, wer in einem Tarifvertrag
als Vertragspartei in Betracht kommt. Auf Arbeitnehmerseite sind
dies Gewerkschaften, auf Arbeitgeberseite entweder der einzelne
Arbeitgeber oder Vereinigungen von Arbeitgebern
(Arbeitgeberverbande). Damit ein Tarifvertrag wirksam ist, muss
neben der Tariffahigkeit (Fahigkeit einen Tarifvertrag als
Vertragspartei abzuschliessen) auch die Tarifzustandigkeit gegeben
sein. Letztere bezeichnet die Zustandigkeit der Verbande fur einen
abzuschliessenden Tarifvertrag; z.B. konnen Verbande der
Metallindustrie keine Tarifvertrage fur den offentlichen Dienst
abschliessen. Das Recht, Tarifvertrage auszuhandeln und
abzuschliessen, geht aus der Tarifautonomie hervor, die
verfassungsrechtlich durch das Koalitionsgrundrecht des Art. 9 Abs.
3 GG garantiert ist. Die Tarifautonomie hat den Sinn, dass die
Ordnung des Arbeitslebens vorrangig selbstandig durch die
Tarifvertragsparteien festgelegt wird und nicht durch den
Gesetzgeber. Tarifvertrage unterliegen als privatrechtliche
Vertrage dem allgemeinen Vertragsrecht nach 145 ff. BGB und gemass
1 Abs. 2 TVG ist fur sie die Schriftform vorgeschrieb
