Phelps’ Lemma, Danes’ Drop theorem and Ekeland’s principle in locally convex spaces
A generalization of Phelps' lemma to locally convex spaces is proven, applying its well-known Banach space version. We show the equivalence of this theorem, Ekeland's principle and Danes' drop theorem in locally convex ...
Dynamics of large wood during a flash flood in two mountain catchments
(European Geosciences Union (EGU) / Copernicus Publications, 2015)
Understanding and modelling the dynamics of large wood (LW) in rivers during flood events has spurred a great deal of research in recent years. However, few studies have documented the effect of high-magnitude flash floods ...
Remarks on the algorithm of Sakawa for optimal control problems
A general optimal control problem for ordinary differential equations is considered. For this problem, some improvements of the algorithm of Sakawa are discussed. We avoid any convexity assumption and show with an example ...
Homoclinic solutions of quasiperiodic Lagrangian systems
(Khayyam Publishing, 1995)
We consider quasiperiodic positive definite Lagrangian systems and establish the existence of one or more solutions homoclinic (namely asymptotic as $t o \pm \infty$) to a quasiperiodic solution. These results are obtained ...
Monitoring of the energy performance of a district heating CHP plant based on biomass boiler and ORC generator
More than seventy district heating (DH) plants based on biomass are operating in South Tyrol (Italy) and most of them supply heat to residential districts. Almost 20% of them are cogenerative systems, thus enabling primary ...
Customer focused strategy development = Kundennutzenorientierte Strategieentwicklung
(Carl Hanser Verlag, 2010)
The success rate of new strategies, products and services can only be increased by a consequent (pre-) orientation to the future markets and respectively the stakeholder’s and the customer’s benefit. This article presents ...
Forced oscillations for singular dynamical systems with an application to the restricted three body problem
We consider forced dynamical systems with two degrees of freedom having singular potentials and we prove existence of infinitely many classical (noncollision) periodic solutions. These solutions have a prescribed rotation ...
