Multimodal Affective Feedback: Combining Thermal, Vibrotactile, Audio and Visual Signals
In this paper we describe a demonstration of our multimodal affective
feedback designs, used in research to expand the emotional expressivity
of interfaces. The feedback leverages inherent associations
and reactions to thermal, vibrotactile, auditory and abstract
visual designs to convey a range of affective states without any
need for learning feedback encoding. All combinations of the different
feedback channels can be utilised, depending on which combination
best conveys a given state. All the signals are generated
from a mobile phone augmented with thermal and vibrotactile stimulators,
which will be available to conference visitors to see, touch,
hear and, importantly, feel
A short note on the presence of spurious states in finite basis approximations
The genesis of spurious solutions in finite basis approximations to operators
which possess a continuum and a point spectrum is discussed and a simple
solution for identifying these solutions is suggested
High pressure flame system for pollution studies with results for methane-air diffusion flames
A high pressure flame system was designed and constructed for studying nitrogen oxide formation in fuel air combustion. Its advantages and limitations were demonstrated by tests with a confined laminar methane air diffusion flame over the pressure range from 1 to 50 atm. The methane issued from a 3.06 mm diameter port concentrically into a stream of air contained within a 20.5 mm diameter chimney. As the combustion pressure is increased, the flame changes in shape from wide and convex to slender and concave, and there is a marked increase in the amount of luminous carbon. The height of the flame changes only moderately with pressure

Pollutant emissions from flat-flame burners at high pressures
Maximum flame temperatures and pollutant emission measurements for NOx, CO, and UHC (unburned hydrocarbons) are reported for premixed methane air flat flames at constant total mass flow rate over the pressure range from 1.9 to 30 atm and for equivalence ratios from 0.84 to 1.12. For any given pressure, maxima typically occur in both the temperature and NOx emissions curves slightly to the lean side of stoichiometric conditions. The UHC emissions show minima at roughly the same equivalence ratios. The CO emissions, however, increase continually with increasing equivalence ratio. Flame temperature and NOx emissions decrease with increasing pressure, while the opposite is true for the CO and UHC emissions. The NOx data correlate reasonably well as a function of flame temperature only. Four flameholders, differing only slightly, were used. In general, the temperature and emissions data from these four flameholders are similar, but some differences also exist. These differences appear to be related to minor variations in the condition of the flameholder surfaces
