Knowledge extraction and insertion from radial basis function networks

IEE Colloquium on Applied Statistical Pattern Recognition, 1999
Neural networks provide excellent solutions for pattern recognition and classification problems. Unfortunately, in the case of distributed neural networks such as the multilayer perceptron it is difficult to comprehend the learned internal mappings.

Microstructural Evolution of Tin Nanoparticles during In Situ Sodium Insertion and Extraction

Nano Letters, 2012
The microstructural changes and phase transformations of tin nanoparticles during electrochemical sodiation were studied with a nanosized sodium ion battery using in situ transmission electron microscopy. It was found that the first sodiation process occurred in two steps; that is, the crystalline Sn nanoparticles were initially sodiated via a two ...

Collagen Versus Xenograft Bovine Bone Inserted Into Extraction Sockets: Healing and Pain Management

Journal of Maxillofacial and Oral Surgery, 2020
Different materials can be used in filling the extraction socket to achieve an alveolar ridge preservation. The present study compared the wound healing potential and pain management efficacy of the collagen and the xenograft bovine bone, covered by a cellulose mesh, inserted into the socket of extracted teeth.Thirteen patients were willingly chosen to

Preparation of LiMn2O4 via dicarboxylates and their lithium extraction/insertion behavior

Solid State Ionics, 1997
Abstract Lithium manganate, LiMn 2 O 4 , powders with different crystallinity were prepared through lithium–manganese-oxalates and -tartrates. The capacity of the plateau at around 4 V increased linearly with the increase of the lattice parameter a 0 and the decrease of lattice strain e , which seemed to be due to the annealing of the ...

Comparative electrochemical sodium insertion/extraction behavior in layered NaxVS2 and NaxTiS2

Electrochimica Acta, 2014
Abstract This study investigates the electrochemical sodium insertion/extraction of NaxVS2, and NaxTiS2 in the voltage range where either intercalation (0.2 ≤ x ≤ 1) or displacement-conversion reaction (x > 1) occurs. Both NaxVS2 and NaxTiS2 showed good reversible capacities, as high as ∼160 mAh/g at an average voltage of ∼1.9 V vs.

Ionic conductivity, lithium insertion and extraction of lanthanum lithium titanate

Solid State Ionics, 2001
The lithium ionic conductivity and electrochemical stability of perovskite La{sub 2/3-x}Li{sub 3x}TiO{sub 3} (LLTO) have been determined with AC impedance spectroscopy, cyclic voltammetry and galvanostatic cycling. Ionic conductivity of La{sub 0.55}Li{sub 0.35}TiO{sub 3} and La{sub 0.57}Li{sub 0.29}TiO{sub 3} pellets sintered from four different ...

Insertion and Extraction of Internal Targetry at the Zero Gradient Synchrotron

IEEE Transactions on Nuclear Science, 1969
A new targetry system within the Zero Gradient Synchrotron (ZGS) changes target manipulators with short interruptions of beam time, no loss of ring vacuum, and minimum exposure of personnel to radiation. The system consists of an insertion-extraction apparatus and two targeting manipulators which use miniature trolley rails.

Hydrogen insertion and extraction mechanism in single-walled carbon nanotubes

AIP Conference Proceedings, 2001
Hydrogen insertion and extraction mechanisms in single-walled carbon nanotubes are studied using density-functional calculations. Hydrogen atoms first adsorb on the tube wall in an arch type and zigzag type upto coverage of 1.0. Hydrogen atoms can be inserted into the tube through the tube wall via flip-in and kick-in mechanism and are stored as a form
