The invisibility cloak of creativity

Robyn Philip
2015 Higher Education Research and Development  
However, removing the invisibility cloak hiding creativity in the higher education curriculum and in teachers' praxis is not without its risks and controversy.  ...  Logistics, timetabling, an inverse relationship between room size and the desire to use the space creatively, ever-evolving educational technology issues, self-efficacy concerns, and mixed messages about  ...

Removing the cloak of invisibility: phenotyping the mouse

M. J. Justice
2008 Disease Models & Mechanisms  
For example, a fasting blood glucose assay is an inexpensive simple assay that may uncover a problem with glucose metabolism, but many other studies would be needed to determine the cause.  ...  These technologies require highly trained and specialized individuals, and handbooks have been devoted to methods for examining an embryonic phenotype (Papaioannou and Behringer, 2005) .  ...

Switchable Virtual, Augmented, and Mixed Reality through Optical Cloaking [article]

Joseph S. Choi
2018 arXiv   pre-print
Optical cloaking allows completely opaque VR devices to be "cloaked," switching to AR or MR while providing correct three-dimensional (3D) parallax and perspective of the real world, without the need for  ...  A simplified stereoscopic system with two cameras and existing VR systems can be an approximation for limited VR, AR, or MR.  ...  Hence, the device should be cloaked to be 'invisible,' or transparent, by its own display.  ...

Evading stepping-stone detection under the cloak of streaming media with SNEAK

Jaideep D. Padhye, Kush Kothari, Madhu Venkateshaiah, Matthew Wright
2010 Computer Networks  
Streaming media does not work well right now as a masking technology, but may become useful if streaming becomes more common between peers using systems like Freecast (see http://www.freecast.org).  ...  The attacker in our system does not pay for the bandwidth and has rather low bandwidth and usability needs, making it more practical in the scenarios we have outlined.  ...

Past, present and future of seismic metamaterials: experiments on soil dynamics, cloaking, large scale analogue computer and space–time modulations

Stéphane Brûlé, Sébastien Guenneau
2021 Comptes rendus. Physique  
We recall that ancient Roman theaters and forests of trees are two examples of large scale structures that behave in a way similar to electromagnetic metamaterials: invisibility cloaks and rainbows, respectively  ...  In the same spirit, a design of an analogous seismic computer is proposed making use of ambient seismic noise.  ...  The similarity between the foundations of the Coliseum in Figure 6 (b) and the design of the invisibility cloak in Figure 1 can be seen in Figure 6 (a).  ...
