Gravity packaging final waste recovery based on gravity separation and chemical imaging control
Waste Management, 2017Plastic polymers are characterized by a high calorific value. Post-consumer plastic waste can be thus considered, in many cases, as a typical secondary solid fuels according to the European Commission directive on End of Waste (EoW). In Europe the practice of incineration is considered one of the solutions for waste disposal waste, for energy recovery ...

ESTER CONTROL IN HIGH GRAVITY BREWING
Journal of the Institute of Brewing, 1974Pilot brewing trials have shown that beers of good flavour can be produced using a high gravity brewing system in which worts of 1080° gravity are fermented and the resulting beers diluted to give an O.G. of 1040°. The flavour can differ from that of the control beers in that the diluted beers retain more ester and strong ale character.

Heart Rate Monitoring and Control in Altered Gravity Conditions
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007On the basis of indirect evidences it has been hypothesized that during space missions the almost complete absence of gravity might impair the baroreflex control of circulation. In the first part of this paper we report results obtained from a series of experiments carried out to directly verify this hypothesis during the 16-day STS 107 Shuttle flight.

Controlling rigid lens centration through specific gravity
International Contact Lens Clinic, 1992Abstract Rigid lens specific gravity may be able to play an important role in controlling vertical lens positioning, particularly in those patients whose current contact lenses do not center well. Ten subjects, five with chronically high-riding rigid lenses and five with low-riding lenses, were fit with lenses of the identical optimal design but of ...

Autobalancing control for a reduced gravity simulator
2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013Physical simulation of a reduced gravity condition significantly aids astronaut training, biomechanics researchers, neuro-rehabilitation practitioners as well as other potential applications. This paper provides means for automatically balancing a simple reduced gravity platform.

Fuzzy control application to guidance control for lunar gravity-turn
2005 International Conference on Machine Learning and Cybernetics, 2005A fuzzy observer-based mixed parallel distributed compensation (PDC) fuzzy controller is utilized to generate guidance law for lunar gravity-turn descent. First, the Takagi-Sugeno fuzzy model is employed to approximate the probe system. Next, based on fuzzy model, a fuzzy observer-based mixed parallel distributed compensation (PDC) fuzzy controller is ...

Absolute gravity as geodetic reference control
Journal of Geodynamics, 1987Abstract Absolute gravity measurements with microgal accuracy represent a new tool for high accuracy vertical reference in properly selected distant sites. They offer therefore an ideal basis for control datum in Africa. As a by-product, eventual gravity changes with time can be followed (variations in water level depth, tectonic phenomena ...

Control Time for Gravity-Capillary Waves on Water
SIAM Journal on Control and Optimization, 1995Distributed open-loop control of small amplitude linear waves is considered on a fluid in which surface tension and gravity are significant. The control system is formulated as a first-order evolution equation, reducing the null controllability problem to a moment problem involving frequency exponentials.

On orbit control using gravity gradient effects
Acta Astronautica, 1981Abstract Possibility of orbit control using gravity gradient (GG) effects without any mass expulsion is discussed. For simplicity, a dumb-bell type satellite and circular orbits are mainly considered. It is shown that the GG effects can be applied to convert attitude torques into orbital torques and vice versa.
