Challenges And Responses For Ensuring Sustainability Of Insa Training Programs, Jongsook Kim, Hyung-Kyung Lee, Jin-Young Lee
International Journal of Nuclear Security
Providing a systematic training is critical for a state or international perspective to reinforce nuclear security regime nationally or internationally. Korea government recognizes the importance of such challenge, and established the INSA under the KINAC as a Center of Excellence for fostering national nuclear security capacity and contributing international nuclear security governance. INSA started with the government policy that the establishment of sustainable education and training infrastructure and processes is fundamental to the capacity building strategy. After established, INSA has been designing and delivering the domestic and international/regional training programs for the purpose of fostering human resources development in nuclear …

INTRODUCTION Ireland has strong tobacco control legislation but must get smokers to stop if the national plan of having a smoking prevalence of 5% by the year 2025 is possible. Involving all healthcare staff in this effort is regarded as important. We surveyed the present situation. METHODS An online survey was conducted of 1257 healthcare staff; 520 nurses, 440 doctors, 297 dentists in 2014. The sample was accessed with the help of the Irish Nurses and Midwifes Organisation (INMO), Irish Medical Organisation (IMO) and the Irish Dental Association (IDA). The questionnaire addressed individual smoking habits and attitudes, training and practice …
Temperature Dependence Of The Training Effect In Exchange Coupled Ferromagnetic Bilayers, Christian Binek, Srinivas Polisetty, Sarbeswar Sahoo
Temperature Dependence Of The Training Effect In Exchange Coupled Ferromagnetic Bilayers, Christian Binek, Srinivas Polisetty, Sarbeswar Sahoo
Christian Binek
The temperature dependence of the training effect is studied in an exchange coupled thin-film bilayer composed of a hard ferromagnetic pinning (CoPtCrB) layer in proximity of a soft ferromagnetic pinned (CoCr) layer. Interlayer exchange shifts the hysteresis loops of the soft layer along the magnetic-field axis. This shift is quantified by the bias field in far reaching analogy to the exchange bias field of conventional antiferromagnetic/ferromagnetic heterostructures. A ferromagnetic domain state induced in the hard layer experiences aging very similar to the training behavior of the antiferromagnetic domain state in conventional exchange bias systems. Training originates from changes in the …
Quenching Of The Exchange Bias Training In Fe/Cr2o3/Fe Trilayer, S. Sahoo, Christian Binek
Quenching Of The Exchange Bias Training In Fe/Cr2o3/Fe Trilayer, S. Sahoo, Christian Binek
Christian Binek
Exchange bias (EB) and its associated training effects are studied in an epitaxial Fe(10 nm)/Cr2O3(2.7 nm)/Fe(10 nm) trilayer heterostructure grown by molecular beam epitaxy. The EB decreases linearly with increasing temperature from T = 5 K to T = 50 K. It changes sign and becomes positive within 50 K < T < 200 K, finally changing back to regular EB for T<200K up to the highest measured temperature of T = 395 K. Remarkably, the latter is far above the bulk Néel temperature TN = 307 K. EB training effects occur only at 5 K < T < 50 K. We show …
Scaling Behavior Of The Exchange-Bias Training Effect, Christian Binek, Srinivas Polisetty, Sarbeswar Sahoo
Scaling Behavior Of The Exchange-Bias Training Effect, Christian Binek, Srinivas Polisetty, Sarbeswar Sahoo
Christian Binek
The dependence of the exchange-bias training effect on temperature and ferromagnetic film thickness is studied in detail and scaling behavior of the data is presented. Thickness-dependent exchange bias and its training are measured using the magneto-optical Kerr effect. A focused laser beam is scanned across a Co wedge probing local hysteresis loops of the Co film which is pinned by an antiferromagnetic CoO layer of uniform thickness. A phenomenological theory is best fitted to the exchange-bias training data resembling the evolution of the exchange-bias field on subsequently cycled hysteresis loops. Best fits are done for various temperatures and Co thicknesses. …
An Investigation Of The Relationship Between Visual Effects And Object Identification Using Eye-Tracking, Jonathan Rosch
An Investigation Of The Relationship Between Visual Effects And Object Identification Using Eye-Tracking, Jonathan Rosch
Electronic Theses and Dissertations
The visual content represented on information displays used in training environments prescribe display attributes as brightness, color, contrast, and motion blur, but considerations regarding cognitive processes corresponding to these visual features require further attention in order to optimize the display for training applications. This dissertation describes an empirical study with which information display features, specifically color and motion blur reduction, were investigated to assess their impact in a training scenario involving visual search and threat detection. Presented in this document is a review of the theory and literature describing display technology, its applications to training, and how eye-tracking systems can …

It changes sign and becomes positive within 50 K < T < 200 K, finally changing back to regular EB for T<200K up to the highest measured temperature of T = 395 K. Remarkably, the latter is far above the bulk Néel temperature TN = 307 K. EB training effects occur only at 5 K < T < 50 K. We show that this training can be quenched by subjecting the system to DC magnetic field, µ0HDC <= 7 T. The applied field most likely induces a temperature dependent spin-flop transition. Upon its removal the antiferromagnetic Cr2O3 pinning layer evolves uniformly into its quasi-equilibrium spin configuration thus leading to quasi-equilibrium EB.
