The Martin XP2M-1 A Martin-built P3M-2 at NAS Pensacola Consolidated flying boat produced for evaluation by Japan The Consolidated P2Y was an American sesquiplane maritime patrol flying boat . The aircraft was also made by Martin as the P3M, as a parasol monoplane, due to the Navy awarding production contracts separately from prototype contracts.
A U.S. Navy PBM-1 of Patrol Squadron 56 (VP-56) in 1940. A PBM-5 on the deck of USS Norton Sound in April 1945 off Saipan A U.S. Navy PBM of Fleet Air Wing 6 is hoisted aboard the seaplane tender USS Curtiss (AV-4) after a mine-hunting patrol off North Korea during the Korean War (1950-1953).

The design was for a flying boat that would make use of boundary layer control (BLC) to achieve slow speed flight. It was intended that this would enable the aircraft to land on the open ocean in rough seas and deploy a dipping sonar.
Particle–Particle–Particle–Mesh (P 3 M) is a Fourier-based Ewald summation method [1] [2] to calculate potentials in N-body simulations. [3] [4] [5]The potential could be the electrostatic potential among N point charges i.e. molecular dynamics, the gravitational potential among N gas particles in e.g. smoothed particle hydrodynamics, or any other useful function.
The 17 wallpaper groups, with finite fundamental domains, are given by International notation, orbifold notation, and Coxeter notation, classified by the 5 Bravais lattices in the plane: square, oblique (parallelogrammatic), hexagonal (equilateral triangular), rectangular (centered rhombic), and rhombic (centered rectangular).
For example, 2 1 is a 180° (twofold) rotation followed by a translation of 1 / 2 of the lattice vector. 3 1 is a 120° (threefold) rotation followed by a translation of 1 / 3 of the lattice vector. The possible screw axes are: 2 1, 3 1, 3 2, 4 1, 4 2, 4 3, 6 1, 6 2, 6 3, 6 4, and 6 5.
FileHippo was established in 2004 by the technology company, Well Known Media, [2] of Ramsey, Isle of Man. [3] The site added a news section in 2014. [4] FileHippo was estimated to be worth over US$13,000,000 in November 2015.
