In this report we examine two topics relating to previous work. We feel that there are points to be made which we have not made before. A common thread in the two problems is that they both involve the isospin variable in an important way. In a publication by Devi et. al. [1] we calculated the excitation energies of T=Tmin+1 states in odd A nuclei and of T=Tmin+2 states of even-even nuclei in t...
We have previously developed artificial neural networks (ANN) dedicated to the analysis of RBS spectra. One of the limitations of the ANNs so far developed was that one single spectrum could be analysed from each sample. When more than one spectrum is collected, each had to be analysed separately, leading to different results and hence reduced accuracy. Here we develop an ANN that can analyse m...
Mobile phones are becoming increasingly sophisticated, enabling consumers to access more services and generate more data. However, the current PIN and password protection capabilities available on mobile phones are often misused resulting insufficient protection of the information stored within mobile phones. Image-based authentication (IBA) leverages the human ability to recognize graphics bet...
InfiniBand is a new standard for communication between processing nodes and I/O devices as well as for interprocessor communication. The InfiniBand Architecture (IBA) supports distributed deterministic routing because forwarding tables store a single output port per destination ID. This prevents packets from using alternative paths when the requested output port is busy. Despite the fact that a...
This briefing sets out some of the key messages from the conference, but also aims to identify possible ideas and answers to the key question of ‘where next?’. As such it explores what the ‘vision’ should be for the future of IBA delivery; what are the key challenges to be addressed from research, policy and practice; and finally, what key actions or ideas will help push this important agenda f...
The suite of techniques which are available with the small accelerators used for MeV ion beam analysis (IBA) range from broad beams, microbeams or external beams using the various particle and photon spectrometries (including RBS, EBS, ERD, STIM, PIXE, PIGE, NRA and their variants), to tomography and secondary particle spectrometries like MeV-SIMS. These can potentially yield almost everything ...
