Nd-Fe-B permanent magnets are characterised by excellent magnetic properties. However, being extremely vulnerable to the attack of both climate and corrosive environments, their applications are limited. This paper describes how, at different thicknesses of N-propyl-trimetoxy-silane, the coating affects the magnetic force of nickel plated magnets. We also investigate if the corrosion resistance of silanized Nd-Fe-B magnets increases in mildly corrosive environments by immersing them in a synthetic saliva solution. It was found that the silanization treatment does not affect the strength of the magnetic force and provide an enhancement of the corrosion resistance of the substrate. © 2013 Elsevier B.V.

This work explores the impact of teaching and learning if the rate of learner engagement outside the classroom is continuously measured and available to the instructor and students. We describe an ongoing implementation of a monitoring tool built within a software engineering continuous integration and testing (CI & Test) platform that integrates multiple streams of student activity and performance on yearlong junior software engineering projects. The CI & Test platform allows for continuous and instantaneous feedback, which we will use to inform student behavior change. In the work-in-progress we describe the technology, its impact on the teaching process for the instructor, and preliminary results observing impacts on student engagement behavior. © 2015 IEEE.
