Mini workshop - Real World Engineering Projects: Discovery-based curriculum modules for first-year students

This mini workshop is organized to provide an interactive forum for the introduction a set of six new curriculum modules developed under IEEE's Real World Engineering Projects (RWEP) program. The modules, which are representative of a larger collection of curriculum modules available to the public via an open-access RWEP web portal, are designed for use in the first-year engineering and computer science classroom, and are hands-on, team-based projects that emphasize the societal impact of the work that engineers do. After a brief introduction to the RWEP program and the six showcased curriculum modules, the authors of the modules will present their ideas and demonstrate the laboratory activities associated with their modules in interactive, informal simultaneous sessions. © 2010 IEEE.published_or_final_versionThe 40th ASEE/IEEE Frontiers in Education Conference (FIE) 2010, Arlington, VA., 27-30 October 2010.

Lattice location and optical activation of rare earth implanted GaN

This paper reviews the current knowledge on rare earths (REs) implanted into GaN with a special focus on their lattice location and on the optical activation by means of thermal annealing. While emission channeling experiments have given information on the lattice location of rare earths following low-dose (≈1013cm-2) implantation, both in the as-implanted state and after annealing up to 900°C, the lattice location of higher-dose implants (1014-1015cm-2) and their defect annealing behaviour were studied using the Rutherford backscattering/channeling (RBS/C) method. The available channeling and luminescence results suggest that the optical activation of implanted REs in GaN is related to their incorporation in substitutional Ga sites combined with the effective removal of the implantation damageCERN/FIS/43725/2001(RENiBEl) HPRI-CT-1999-0001

Random-digit dialling in the UK: viability revisited

A main obstacle to using telephone methods for social surveys in the UK has been the inability to select a representative and unbiased probability sample of the general population. However, recent changes in the UK telephone numbering system and advances in telephony software appear to provide the means for using random-digit dialling (RDD). This paper presents the results of a study designed to test the feasibility of RDD. The focus is on the sampling method, but we also assess other aspects of the RDD survey method, in the context of a total survey error framework. Although we conclude that RDD is now a viable survey method in the UK, further research and development is advocated to improve the efficiency of fieldwork and response rates.
