  • Blade platform gusset with internal cooling
    Patent number: 10677070
    Abstract: A blade assembly includes a blade and a blade platform secured to the blade. The blade extends radially from the blade platform. The blade platform includes at least one platform airflow passage located therein. A gusset extends from the blade to the blade platform. The gusset includes a gusset airflow passage fluidly connected to the platform airflow passage to convey an airflow to the platform airflow passage. a gas turbine engine includes a combustor and a plurality of gas turbine engine components located in fluid communication with the combustor. The gas turbine engine component includes an airfoil portion and a platform secured to the airfoil portion. The platform includes at least one platform airflow passage positioned therein. A gusset extends from the airfoil portion to the platform. The gusset includes a gusset airflow passage fluidly connected to the platform airflow passage to convey an airflow to the platform airflow passage.

  • Methods for identifying large subsets of differentially expressed genes based on multivariate microarray data analysis
    Publication number: 20060088831
    Abstract: The present invention provides multivariate methods for identifying differentially expressed genes based on microarray expression data. An improved random search procedure involving certain probability distances is provided. The methods of this invention implement a successive elimination procedure to remove smaller subsets resulted from each step of the random search thereby establishing a larger set of differentially expressed genes.

  • Methods for identifying differentially expressed genes by multivariate analysis of microaaray data
    Publication number: 20040265830
    Abstract: The present invention applies pattern recognition and multidimensional classification in statistical microarray data analysis. There are provided methods for identifying a subset of genes that are differentially expressed under a given biological state or at a given biological locale of interest by determining an advantageously large probability distance between the random vectors representing expression levels of the genes of interest. The invention also provides a cross-validated random search mechanism for a subset of genes based on various probability distances between two random vectors.
