Patent number: 8589127Abstract: A computer-implemented method of simulating behavior of a thermodynamic system over time, the thermodynamic system having a state described by collective vectors of position and momentum at any given time and the method comprising a momentum refreshment process, a conservative dynamics process, and an acceptance/rejection process, wherein the momentum refreshment process comprises mixing the collective momentum vector with a noise vector; the conservative dynamics process comprises applying a mollified impulse multiple time stepping conservative dynamics method to a current state, in which process calculations for forces corresponding to more slowly varying energy parts in the thermodynamic system undergo an averaging procedure and are carried out at a larger time step than calculations for forces corresponding to more quickly varying energy parts; and wherein the acceptance/rejection process is based on the system energy and comprises accepting a current state or returning a replacement state.Type: GrantFiled: June 25, 2010Date of Patent: November 19, 2013Assignee: Fujitsu LimitedInventors: Elena Vitalievna Akhmatskaya, Sebastian Reich

Patent number: 6068586Abstract: A laboratory centrifuge has a housing which can be closed by a casing cover and having in the housing a rotor chamber which contains a motor-driven vertical-axis rotor to accept test tubes. During operation, the test tubes are warmed by friction. To cool the centrifuge, cooling air is pulled in through openings in the lower side of the housing and upward into the rotor chamber by the fan action created by the rotation of the rotor. The air is guided out of the rotor chamber through an air exit in a direction of flow tangential to the perimeter of the rotor in a manner that ensures low turbulence and, thus, low noise. In particular, a slit-like air exit opening is arranged between the casing cover and the top side of the housing.Type: GrantFiled: January 29, 1999Date of Patent: May 30, 2000Assignee: Kendro Laboratory Products GmbHInventors: Michael Koch, Detlev Demmig, Rudiger Uhlendorf, Sebastian Reich
