    Abstract: A method of presuming interior situation of process chamber that makes it possible to accurately presume the interior situation of a process chamber using the number of particles discharged from the interior of the process chamber. Characteristic values associated with respective particle removing modes of a particle removing sequence are extracted from time-series data on the number of particles discharged from the interior of the process chamber in which a substrate is accommodated and subjected to predetermined processing and to which the particle removing sequence is applied, and the relationship between the extracted characteristic values and the interior situation of the process chamber is calculated. The interior situation of the process chamber is presumed based on the calculated relationship and the characteristic values in new time-series data on the number of particles.

  • Patent number: 8359163
    Abstract: The present disclosure relates to a method to improve the performance of reservoir simulators, and to widen the range of systems that can efficiently be modeled. The present disclosure relates to determining fluid flow in a subsurface reservoir. One embodiment divides the reservoir into discrete volume elements. Fluid within the volume elements is represented, for example, by it pressure, saturation, and/or composition. For one or more fluid phases comprising the fluid, the potential for each volume element is determined. The volume elements are ordered according to their potentials for each phase comprising the fluid. A local, fully coupled time-step sequence is determined using a local conservation solution based on the potential ordering of and for each fluid phase. The fluid flow is determined using a global conservation solution based on the local, fully coupled time-step sequence.

  • Patent number: 8332172
    Abstract: A digitizing instrument is used for modifying pattern data and jitter and noise components of a communication signal. In a typical implementation, the midpoints of a rising edge slope and horizontal portion of the communication signal are determined and multiple digital data records are acquired at the midpoints. The data sample records are transformed to frequency components and the random jitter and noise, and periodic jitter and noise components are determined. A correlated pattern data and the jitter and noise components are matrix elements in a simulated signal channel having communication system elements. Each correlated pattern data and jitter and noise component may be modified for each of the communication system element. The selectively modified correlated pattern data and jitter and noise components are combined to produce a modified communication signal that is displayed as a numeric table, eye diagram or bit error rate presentation.
