Designing Safe 2.5D Tangible Shape Displays

2.5D shape display is a recent idea in the market that emerged as a platform of interaction between a computer and human. 2.5D shape display is essentially a grid-like matrix consisting of actuators and pins moving up and down in vertical motion to create pseudo-3D images. Focused as a visual display in some applications and as a medium of input...

Exploratory system dynamics: A directed search for limits to global water use

Rockström et al. (2009) introduced the concept of a safe operating space for humanity that will not push the planet out of the ‘Holocene state’. These limits are being investigated for various earth bound systems. Estimates of these limits are plagued by uncertainty. In case of the limits to the world water system, these uncertainties arise out...

Blue limits of the Blue Planet: An exploratory analysis of safe operating spaces for human water use under deep uncertainty

In the Nature article ‘A safe operating space for humanity’, Rockström et al. (2009) introduce the concept of a safe operating space for humanity. A safe operating space is the space for human activities that will not push the planet out of the ‘Holocene state’ that has seen human civilizations arise, develop, and thrive. Rockström et al. have...

Characterization and AlN cooling of thermally isolated bipolar transistors

Nowadays, electrothermal effects (ET) are posing fundamental issues in nearly all branches of micro- and nano-electronics. Due to either a high power dissipation level or to the aggressive electrical isolation schemes adopted to increase the speed, both high and low power devices are affected by ET effects that limit their reliability and cause...
