The P-CURVE (Sklenar et al., 1989) algorithm uses an helicoidal axis approach derived from a series of peptide planes to assign secondary structure.
The facility is composed of a loop of glass tubes, a heat source using electrical heaters, a cold source using a helicoidal heat exchanger, a visualization section and thermocouples positioned over different loop sections.
Larger droplets are separated as they enter the cyclone housing, while the smaller droplets are carried by the gas into the helicoidal path of the rotating element, where they are centrifuged towards the outer collecting walls and, due to a baffle, flow counter-currently to the gas and are drained out from the bottom of the helicoidal element.
The element may be used as a plane element or as an axisymmetric element.
It is an improvement over the current fiber bending distributed sensors that use a polymer cable that interacts with an optical fiber by means of a helicoidal wire.
The collection efficiency of a new helicoidal rotary demister, a novel technology for removing persistent fine droplets from gases, was evaluated using a tracer-based method.
Using the Discrete Element Method (DEM), a sensitivity study has been carried out to investigate the minimal barrel thickness with respect to the: a) angle of skew; b) construction method (false, helicoidal, and logarithmic); c) size of masonry units; and d) frictional resistance between masonry units.
Furthermore, using advanced finite element analysis (FEA) code LS-DYNA® for simulating LVI and CAI events, it was revealed that the helicoidal arrangement endured the least amount of fibre damage.
However, for skew arches constructed using the helicoidal and logarithmic method, as the angle of skew increases, the minimum barrel thickness decreases.
However, for skew masonry arches constructed using the helicoidal and logarithmic method, as the angle of skew increases, the failure load increases.
