Kernel Penalized K-means: A feature selection method based on Kernel K-means
(Elsevier, 2015)
We present an unsupervised method that selects the most relevant features using an embedded strategy while maintaining the cluster structure found with the initial feature set. It is based on the idea of simultaneously ...
A new approach for k(L)a determination by gassing-out method in pneumatic bioreactors
(Wiley-Blackwell, 2016-12-01)
BACKGROUND: Determination of the volumetric oxygen transfer coefficient (k(L)a) is very important for bioreactor design and process analysis. Among all the methods available, the gassing-out technique is one of the simplest ...
Three dimensional k-space trajectory design using genetic algorithms
(ELSEVIER SCIENCE INC, 2003)
Image quality and total scan time in MRI are determined in large part by the trajectory employed to sample the Fourier space. Each trajectory has different properties like coverage of k-space, scan time, sensitivity to ...
k 0-INAA as a contributor in nutrition and health: multielemental determination in Stevia rebaudiana Bertoni, leaves and stevioside product
(Springer NetherlandsPE, 2018-02)
Concerned about food safety and considering the advantages that bring the use of the powerful INAA technique based in k0 method, we have decided to perform a complete multi element determination in the leaves and in the ...
Aeration step method for k(L)a measurement under growth conditions in pneumatic bioreactors
(Wiley-Blackwell, 2019-07-01)
Background Determination of the volumetric oxygen transfer coefficient (k(L)a) plays an important role in the design and characterization of bioreactors. Among all methods available, few techniques are suitable for the ...
