Eine Aussage über das Verhalten eines geplanten Windrades kann auf drei prinzipiell unterschiedlichen Wegen erhalten werden: 1.) rein theoretische Berechnungen, 2.) Versuche im Windkanal, 3.) Untersuchung bereits gebauter ...
Lindemann, Dieter(West Lafayette, Indiana, USA : School of Mechanical Engineering, Purdue University, 1987)
Research was conducted to obtain design data of latent heat-of-fusion thermal energy storage (LHTES) devices. The devices studied utilize a porous medium (PM) to increase the effective conductivity of the storage system. ...

The search for renewable and clean energy sources is a key aspect for sustainable development as energy consumption has continuously increased over the years concomitantly with environmental concerns caused by the use of ...
In this study, we comprehensively examine the volatility term structures in commodity markets. We model state-dependent spillovers in principal components (PCs) of the volatility term structures of different commodities, ...
The delta of the Mekong River in Vietnam has been heavily impacted by anthropogenic stresses in recent years, such as upstream dam construction and sand mining within the main and distributary channels, leading to riverbank ...
The prevention of infectious diseases is particularly important in athletes who need a good all-season health status to be optimally prepared for competition. › Since the immune system is highly responsive to exercise, ...

In this article, we report the results of comparative studies of photoelectrochemical behavior of the binary CdS/TiO2 and WO3/TiO2 and ternary CdS/WO3/TiO2 heterostructures based on titania nanotube and planar structures. ...
Piled rafts have been used as a foundation system for high-rise buildings worldwide in different soil conditions, e.g., in soft to stiff clay as well as in medium-to-dense sand. Piled raft is currently used not only to ...
Stakeholders are important for software projects as they help to define the requirements. However, in case of multiple stakeholders with different viewpoints, it is often difficult to find a suitable solution for almost ...
The availability of bioresources is a precondition for life science research, medical applications, and diagnostics, but requires a dedicated quality management to guarantee reliable and safe storage. Anecdotal reports of ...
Background: The relevance of regular moderate to intense exercise for ameliorating psychomotor symptoms in persons with multiple sclerosis (pwMS) is becoming increasingly evident. Over the last two decades, emerging evidence ...

Learners’ academic self-concepts and attributions have been widely evidenced to substantially regulate their educational development. Develop-mentally, they will not only operate in a mutually reinforcing manner. Rather, ...
Objectives Our study investigates the barriers perceived by staff in the referral systems in maternal healthcare facilities across Aceh province in Indonesia. Design With a cross-sectional approach, two sets of surveys ...
Politova, G.; Ganin, M.; Kaminskaya, T.; Mikhailova, A.; Nacke, B.; Filimonov, A.; Burkhanov, G.(Bristol : Institute of Physics Publishing, 2019)
The effects of partial substitution of dysprosium in Tb0.2Dy0.8Co2 by terbium and gadolinium on the structure and magnetic properties have been studied. Two compositions, Tb0.3Dy0.7Co2 and Tb0.2Dy0.7Gd0.1Co2 have been ...
Precise knowledge of the temperature that arises in the material during plastic forming is of crucial importance, as it has a significant influence on material behaviour and therefore on the forming process. In order to ...

In this paper, passive mode-locking in Ti:sapphire laser with a coherent absorber cells with rubidium vapor placed in the cavity is demonstrated experimentally. For the best of our knowledge these experiments are the first ...
Wick, Thomas(Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
The goal of this winter school is to give an introduction to numerical modeling
of multiphysics problems. These are nonstationary, nonlinear, coupled partial
differential equations. The philosophy of this school is to ...
For physical model tests, the time-varying characteristics of tidal currents are often simplified by a hydrograph following a shape of a unidirectional current or by resolving the tidal velocity signal into discrete steps ...
