Abstract

The work presented introduces a system that encompasses general notions about the dashboard computer and Arduino platform, used to create an automotive diagnostic tool through the OBDII port. This involves establishing a connection between the Arduino platform, a Bluetooth module, and a Bluetooth adapter that communicates with the Engine Control Unit (ECU), transmitting information displayed on an LCD screen. To highlight the system's performance, a comparison of results was conducted with an authorized automotive tester from an auto service, using two different vehicle models. [ABSTRACT FROM AUTHOR]

2. The Influence of Annealing Thermal on the Properties of Au:TiO2 Nanocomposite Film

Abstract

Two sets of nanocomposite films consisting of different atomic concentrations of Au dispersed in a TiO2 dielectric matrix were deposited by DC reactive magnetron sputtering, and subjected to several annealing trataments in vacuum, for temperatures ranging from 300 to 800 0C. The obtained results show that the structure and the size of Au clusters, together with the matrix crystallinity, changed as a result of the annealing As a result of these structural variations the film optical properties were modified too. The optical changes, and the correspondent Surface Plasmon Resonance effect were confirmed by reflectivity and CIELab colour measurements. XRD analysis confirmed the presence of gold in all the samples, and the crystallization of the TiO2 matrix for the samples annealed at temperatures above 4000C. With further increase of the annealing temperature, there is a change from the TiO2 anatase phase into rutile-type structure. Simultaneously, the Au atoms are organized in crystalline nanoparticles (revealing an fcc-type structure, with the (111) preferential growth orientation).

Abstract

We present a new concept for a high energy gamma ray telescope with an extended energy range and excellent energy and angular resolution. Astrogam is a pair production telescope which was designed to use the magnetic field of the Space Station Freedom Astrogam facility to separate the e+‐e− pair and accurately measure the momentum of each particle (Eichler and Adams 1987). Astrogam will extend spectral measurements to higher energies, thus closing the gap between satellite and ground‐based observations.
