Ionizing radiation has long been used in medicine since the discovery of X-rays. Diagnostic imaging using synchrotron radiation has been under investigation since Rubenstein et al. reported dual-energy iodine-K-edge subtraction coronary angiography. Recent ...
The microstructure of gas source molecular beam epitaxy GaN films deposited on (0001) sapphire is studied by transmission electron microscopy. For a nucleation layer deposited at 500 degrees C, high-quality materials, with only dislocations (density = 5 x ...
Most quality management systems (QMS) which integrate software development are based on a single software development method. This particular method is enforced on all projects. The resulting QMS has to fulfil the ISO 9000 standards [13] and enables the co ...
We present a simple, original method to improve piecewise linear interpolation with uniform knots: We shift the sampling knots by a fixed amount, while enforcing the interpolation property. Thanks to a theoretical analysis, we determine the optimal shift t ...
We extend the range of inverse kinematics by integrating mass distribution information to embody the position control of the center of gravity of any articulated figure in single support (open tree structure). The underlying control architecture of main an ...
In this paper we present our motivations for proposing of a generic model for the description of quality attributes of software artifacts, in particular suited to software components. The conceptual ideas for our quality description model are derived from ...
This paper presents the effort that has been undertaken in designing and building both hardware and software for a fully autonomous navigating vehicle aimed for a tour guide application. The challenge for such a project is to combine industrial high qualit ...
Ammonia as nitrogen precursor has been used to grow m-V nitrides by molecular beam epitaxy (MBE) on c-plane sapphire substrates. The efficiency of NH3 has been evaluated allowing the determination of the actual V/III flux ratio used during the GaN growth. ...
In this paper we review the present status of electron spectroscopy of Ce and Yb Kondo systems, with particular emphasis on photoemission and inverse photoemission. Our starting point is the situation in the mid-1980s, characterized by the development of a ...
The goal of this paper is to present a multi-media telecommunication architecture based on ATM technology, which provides reliable and effective transmission of still and motion high resolution (1024x1024 up to 4096x4096, 16 or 32 bits/pixel radiological a ...
