During operation, the system can determine a quenched acid profile from an initial acid profile by applying multiple quenching models which are associated with different acid concentration ranges to the initial acid profile. One quenching model may be expressed as H=H0?B0, where H is an acid profile after quenching, H0 is an acid profile before quenching, and B0 is an initial base quencher profile. Another quenching model may be expressed as H=k·H0, where k is a constant. Next, the system can apply a smoothing kernel to the quenched acid profile to obtain a quenched-and-diffused acid profile. The smoothing kernel can generally be any weighted averaging function. The quenched-and-diffused acid profile can then be used to predict shapes that are expected to print on the wafer and to perform resolution enhancement techniques on a layout.Type: GrantFiled: July 28, 2009Date of Patent: April 17, 2012Assignee: Synopsys, Inc.Inventor: Yongfa Fan

Publication number: 20120065948Abstract: Described are computer-based methods and apparatuses, including computer program products, for monitoring, detecting, and quantifying chemical compounds in a sample. A sample measurement comprising a digitized spectroscopic profile is received. A multivariate multistage background model comprising a first model that models a first time effect, a second model that models a second time effect that is different than the first time effect, or both is calculated. A background corrected sample measurement based on the sample measurement and the multivariate multistage background model is generated. A multivariate multistage library search, fault detection, and quantification algorithm is executed to identify one or more primary chemicals in the background corrected sample measurement.Type: ApplicationFiled: September 13, 2010Publication date: March 15, 2012Applicant: MKS Instruments, Inc.Inventors: Huwei Tan, Svante Bjarne Wold

Publication number: 20120059599Abstract: A system and method generate a structure activity relationship model to determine whether unknown chemical compounds are of a desired classification where the structure activity relationship model is based on a set of known chemical compounds having known structural and/or biological descriptors. A system and method utilize a structure activity relationship model to determine whether unknown chemical compounds are of the desired classification, where descriptors of the known chemical compounds are compared to structural and/or biological descriptors of the unknown chemical compounds to determine whether the test chemical compounds are of the desired classification. A system and method generate a structure activity relationship model to study how particular agents may induce disease or act as therapeutic agents. The model may also be used to study how groups of agents induce disease or act as therapeutic agents and to study the etiology and treatment of disease in general.Type: ApplicationFiled: September 2, 2011Publication date: March 8, 2012Applicant: UNIVERSITY OF LOUISVILLEInventors: Albert Cunningham, John O.

Patent number: 8131480Abstract: The present invention concerns the design and construction of diverse peptide and polypeptide libraries. In particular, the invention concerns methods of analytical database design for creating datasets using multiple relevant parameters as filters, and methods for generating sequence diversity by directed multisyntheses oligonucleotide synthesis. The present methods enable the reduction of large complex annotated databases to simpler datasets of related sequences, based upon relevant single or multiple key parameters that can be individually directly defined. The methods further enable the creation of diverse libraries based on this approach, using multisynthetic collections of discrete and degenerate oligonucleotides to capture the diverse collection of sequences, or portions thereof.Type: GrantFiled: September 28, 2007Date of Patent: March 6, 2012Assignee: Sea Lane Biotechnologies LLCInventors: Lawrence Horowitz, Ramesh Bhatt, Aaron L.

Publication number: 20120052408Abstract: A system and method for correcting an estimation of nitrogen in an anode side of a fuel cell stack. The system includes a fuel cell stack and a pressure sensor for measuring pressure in an anode sub-system. The system also includes a controller configured to control the estimation of nitrogen permeation from the cathode side to the anode side of the stack, where the controller determines if the pressure in the anode sub-system equilibrates with atmospheric pressure in a shorter period of time after shutdown compared to the time necessary for the anode sub-system to reach approximately atmospheric pressure after a previous shutdown or calibrated time value, and corrects the estimation of nitrogen in the anode side of the stack if the pressure equilibrates in a shorter period of time.Type: ApplicationFiled: August 25, 2010Publication date: March 1, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Matthew A.

Patent number: 8126575Abstract: A method for building robust model predictive controller universally applicable is presented based on the innate process characteristics independent of the method of control actuation. The method of universal MPC design permits proper configuration of requisite regulatory control loops for measured and unmeasured disturbance rejections consistent with the underlying innate process characteristics and their embedding within the overall process unit model predictive controller. The method of universal MPC design requires that manipulated variables process value based model (PV-based models) be used in control and optimization in place of the customary set point based models (SP-based models) or control output based models (OP-based models). The PV-based models are devoid of the manipulated variables regulatory controllers response and tuning. Based on the PV-based models, an alternate method of MPC called PV-based MPC is presented that is most robust and adaptable of possible three types of MPC.Type: GrantFiled: March 25, 2009Date of Patent: February 28, 2012Assignee: Fakhruddin T AttarwalaInventor: Fakhruddin T Attarwala

Patent number: 8120771Abstract: By means of an improved configuration method, mathematical transport models can be fitted to correlations determined by means of scanning fluorescence spectroscopy with few errors. With improved methods for carrying out or evaluating a raster image correlation spectroscopy measurement (RICS) measurement, the amount of data to be stored can be reduced and RICS correlations of high statistical quality can be determined within a short period of time. For a raster image correlation spectroscopy measurement, a best value for a sampling value is determined and is specified for a subsequent scanning process on a sample. In order to carry out or evaluate a RICS measurement, sampling values are acquired or a correlation is determined exclusively in a sample region within which a pixel time (?P) changes along a harmonically controlled scan axis (X) by less than, or at most by, a predetermined or predeterminable value.Type: GrantFiled: September 30, 2008Date of Patent: February 21, 2012Assignee: Carl Zeiss MicroImaging GmbHInventors: Stephan Wagner-Conrad, Frank Hecht, Klaus Weisshart, Ralf Netz
