Towards disappearing user interfaces for ubiquitous computing: human enhancement from sixth sense to super senses

The enhancement of human senses electronically is possible when pervasive computers interact unnoticeably with humans in Ubiquitous Computing. The design of computer user interfaces towards “disappearing” forces the interaction with humans using a content rather than a menu driven approach, thus the emerging requirement for huge number of non-technical users interfacing intuitively with billions of computers in the Internet of Things is met. Learning to use particular applications in Ubiquitous Computing is either too slow or sometimes impossible so the design of user interfaces must be naturally enough to facilitate intuitive human behaviours. Although humans from different racial, cultural and ethnic backgrounds own the same physiological sensory system, the perception to the same stimuli outside the human bodies can be different. A novel taxonomy for Disappearing User Interfaces (DUIs) to stimulate human senses and to capture human responses is proposed. Furthermore, applications of DUIs are reviewed. DUIs with sensor and data fusion to simulate the Sixth Sense is explored. Enhancement of human senses through DUIs and Context Awareness is discussed as the groundwork enabling smarter wearable devices for interfacing with human emotional memories

SPIN ROTATION IN GdCo2

Une étude de l'effet Mössbauer de 57Fe dans GdCo2 est présentée. Les mesures révèlent un spin de l'axe cubique [100] en dessous de 200 K, à l'axe [110] au-dessus de 290 K. Dans l'intervalle entre ces deux températures, la magnétisation prend des directions non majeures. Le spin dans GdCo2 peut être expliqué par le traitement phénoménologique de l'énergie anisotropique magnéto-cristalline.A Mössbauer study of 57Fe in GdCo2 is reported. The measurements reveal a spin rotation from the [100] cubic axis below 200 K, to the [110] axis above 290 K. Over the spin rotation temperature interval, the easy magnetization assumes non-major directions. The spin rotation in GdCo2 can be acounted for in terms of a phenomenological treatment of the magnetocrystalline anisotropy energy

STUDY OF ITINERANT FERROMAGNETISM IN Zr1-xTixZn2 AND Zr1-yHfyZn2 BY MAGNETIC RESONANCE

La substitution partielle du zirconium par des éléments possédant des électrons 3 d et 5 d tels que Ti ou Hf change profondément les propriétés magnétiques du ZrZn2. Nous avons étudié systématiquement les résonances magnétiques du Zr1-xTixZn2 et du Zr1-yHfyZn2 en fonction de la température, de la fréquence et de la concentration. Nous supposons que la largeur de raie de E. P. R. au-dessus de Tc est due surtout à la relaxation spin-réseau. Au-dessous de Tc, la largeur de raie dépend de la fréquence, ce qui indique la présence de mécanismes additionnels d'élargissement. Les théories en cours ne peuvent expliquer le comportement du déplacement du g.The magnetic properties of ZrZn2 are significantly changed by partly substituting the Zr with 3 d and 5 d elements such as Ti and Hf. The magnetic resonance of Zr1-xTixZn2 and Zr1-yHfyZn2 was systematically investigated as function of temperature, frequency and concentration. The E. P. R. line width above Tc is mainly attributed to spin-lattice relaxation. Below Tc the line width depends on the frequency, indicating additional broadening mechanisms. The g shift behaviour is not explained by existing theories

Quantification of the release rate of the aggregation pheromone of the western flower thrips, Frankliniella occidentalis (Pergande), using solid-phase microextraction (SPME).

The aggregation pheromone of the western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), has previously been identified as the monoterpenoid ester neryl ( S )-2-methylbutanoate. It attracts both male and female adults to traps in commercial glasshouses. In this paper, we investigate the rates of production of this compound at two male densities and in the presence or absence of an adult female. Solid-phase microextraction (SPME) was used to entrain live-male headspace odour and this was compared with external standards to obtain an estimate of pheromone production, which was about 100–300 pg male −1 h −1 . Significantly more pheromone was apparently produced per male at the higher density, but no firm conclusions could be drawn because the rates were close to the limits of resolution. The rate of production was not affected by the presence of a female thrips. Another male-headspace component, ( R )-lavandulyl acetate, was only detectable at the higher male density
