Interests and limitations of nanoindentation for bulk multiphase material identification: Application to the β phase of Ti-5553

This paper focuses on the numerical modeling of nanoindentation tests. The first goal of this study is to collect essential material parameters and boundary conditions from the literature and to complete the data required to accurately model nanoindentation tests. The second goal of this study consists in validating the material parameters identified from macroscopic tensile tests of the body-centered cubic b phase of Ti-5553, a new generation of titanium alloy. This validation is performed looking at experimental and numerical nanoindentation curves obtained for different grain orientations

UWB MAC and Network Solutions for Low Data Rate with Location and Tracking Applications

The object of this paper is to present the main results achieved during the first fifteen months of the 6th framework European Union integrated research project PULSERS [1], regarding Ultra Wide Band (UWB) Medium Access Control (MAC) and network layer issues for low data rate with location and tracking (LDR-LT) applications. Various intended UWB system architectures and their key requirements and parameters are introduced. For such systems, potential MAC schemes and network solutions are illustrated and discussed. New ideas about wireless UWB access, synchronization, resource allocation, and topology management are also presented
