Cultivating Sailor Ethical Fitness

Weaving together multiple philosophical threads, this sketch of an ethical fitness concept avoids a legalistic focus on rule breaking to develop ethical competence that is both operationally effective in time-constrained, dynamic environments, including combat, and useful for sailors performing their daily tasks

The Restorative Prison: Essays on Inmate Peer Ministry & Prosocial Corrections

Drawing on work from inside some of America’s largest and toughest prisons, this book documents an alternative model of restorative corrections utilizing the lived experience of successful inmates, fast disrupting traditional models of correctional programming. While research documents a strong desire among those serving time in prison to redeem themselves, inmates often confront a profound lack of opportunity for achieving redemption. In a system that has become obsessively and dysfunctionally punitive, often fewer than 10% of prisoners receive any programming. Incarcerated citizens emerge from prisons in the United States to reoffend at profoundly high rates, with the majority of released prisoners ending up back in prison within five years. In this book, the authors describe a transformative agenda for incentivizing and rewarding good behavior inside prisons, rapidly proving to be a disruptive alternative to mainstream corrections and offering hope for a positive future

Modelling the effect of gaps and overlaps in automated fibre placement (AFP)-manufactured laminates

AbstractIn automated fibre placement (AFP) process, gaps and overlaps parallel to the fibre direction can be introduced between the adjoining tapes. These gaps and overlaps can cause a reduction in strength compared with pristine conditions. Finite element modelling is an effective way to understand how the size and distribution of such gaps and overlaps influences the strength and failure development. Many modelling work showed that out-of-plane waviness and ply thickness variations caused by gaps and overlaps play an important role in inducing the strength knock-down; however, there has been a lack of effective way to explicitly model the ply waviness, which constrained the relevant research. In this work, 3D meshing tools were developed to automatically generate ply-by-ply models with gaps and overlaps. Intra-ply and inter-ply cohesive elements are also automatically inserted in the model to capture the influence of splitting and delamination. Out-of-plane waviness and ply thickness variations caused by gaps and overlaps are automatically modelled. Models with various sizes and distribution of gaps and overlaps were built to predict the reduction of strength as a function of the magnitude and type of the defects. Results of gap and overlap models will be used to guide future experimental characterization of simulated AFP process defects, manufactured by hand layup from pre-preg tape.</jats:p

Technique for Predicting the Radio Frequency Field Strength Inside an Enclosure

This technical memo represents a simple analytical technique for predicting the Radio Frequency (RF) field inside an enclosed volume in which radio frequency occurs. The technique was developed to predict the RF field strength within a launch vehicle fairing in which some payloads desire to launch with their telemetry transmitter radiating. This technique considers both the launch vehicle and the payload aspects
