The setting level of an hydraulic machine, specially for low head machines, is decided with respect to the possible alteration of the efficiency due to the cavity development. This alteration can easily be noticed by plotting the evolution of the efficienc ...
Implantation of Ni ions into pure aluminium shows the formation of amorphous zones (AZ). Measurements by energy dispersive spectrometry attribute to the amorphous zones at Ni concentration of 25 at.%. These amorphous regions are relatively stable under hea ...
structural defects induced by He implantation in GaN epilayer at high fluence (1 X 10(17) He/cm(2)) and elevated temperature (750 degrees C) have been studied by conventional and high resolution transmission electron microscopy. In addition to the planar i ...
In order to create a new solar aircraft totally powered by the sun, a new method able to handle such a complex system must be developed. The project aim is to make a round-the-world flight in so as to promote the sustainable development. The aircraft power ...
The paper proposes a new method to determine the tooth cogging force in a brushless DC (BLDC) motor which is used in a hard-disk application. This force might be a source of tooth vibrations and motor noise. In the new method, the permanent-magnet (PM) pol ...
The soft tissue, called periodontal ligament (PDL), that connects the alveolar bone and the tooth root accounts to a large extent for the mobility, stress-distribution and, due to its viscoelastic properties, damping of the bone-tooth complex. The accurate ...
Predicting the rate and location of cavitation erosion is a complex problem that motivated an important amount of basic and applied research in the fields of hydrodynamics, mechanical science and metallurgy. Using an original approach, the so-called energe ...
The setting level of a hydraulic machine, specially for low head machines, is decided with respect to the possible alteration of the efficiency due to the cavity development. This alteration can easily be noticed by following the evolution of the efficienc ...
A theoretical investigation of the dynamics in a photoluminescence experiment in strong-coupling semiconductor microcavities is presented. Radiative recombination rates of microcavity polaritons in the strong-coupling regime and their scattering rates with ...
