Power-to-Gas (PtG) represents one of the most promising energy storage technologies. PtG converts electricity surplus into synthetic natural gas by combining water electrolysis and CO2 methanation. This technology valorises captured to produce a ‘carbon neutral’ gas, while allowing temporal displacement renewable energy. PtG-Oxycombustion hybridization is proposed integrate mass flows global sy...

Atomic force microscopy (AFM), neutron reflection (NR) and secondary ion mass spectroscopy (SIMS) are used to examine phase separation in symmetrically segregating thin polymer blend films (e1000 Å). Phase separation in the film leads to undulations of the liquid-air interface, provided the film is sufficiently thin to suppress surface-directed spinodal decomposition waves. Flattened droplets a...

A data-mining approach is applied to optimize the energy consumption of an air handling unit. A multiperceptron ensemble algorithm is used to model a chiller, a pump, and the supply and return fans. A non-linear model is developed to minimize the total energy consumption of the air-handling unit while maintaining the temperature of the supply air and the static pressure in a predetermined range...

The analysis of bubble clustering in air-water flows may provide some measure of the bubble-turbulence interactions. A cluster of bubbles is as a group of two or more bubbles, with a distinct separation from other bubbles. This paper compares the results of a clustering study in a dropshaft and in a hydraulic jump to point out differences/similarities between those complex turbulent flows. The ...

Having a user-friendly Human-CAD interaction with high speed and accuracy plays a key role in development of future intelligent modeling environments. A major part of this puzzle is sketch identification using either 2D gestures -which is commonly recorded from mouse, light pen and touchpador air gestures captured from some newly emerged devices such as Leap Motion and Soft-Kinect. To this end,...

An automated forced-choice dynamic-dilution olfactometer has an odor evaluation module having two or more panelist stations, with a plurality of sniffing ports at each station. At least one signal element at each station is connected to a data control unit. Separate air lines are connected to one each of the sniffing ports at each station. One of the air lines has an odor introduction port. The...

Plastics collection poses a quandary: if one wishes the easiest collection, the citizen must be given very simple instructions as to what plastics to set out; if the maxi­ mum collection of the many recyclable plastics is desired, one must accept mixed plastics. In either case, process­ ing is necessary: in the first, to control contamination; in the second to separate the polymers. Many sophis...

In a Free Flight Environment, managing separation between aircraft is delegated to the pilot by Air Traffic Management. The future adoption of a Free Flight Environment is necessary, as Air Traffic Controllers will be unable to handle the workload from the forecasted doubling of air traffic within two decades. The responsibility of pilots will expand to include a new set of cognitive demands as...
