Survanta, a clinically used bovine lung surfactant extract, in contact with surfactant in the subphase, shows a coexistence of discrete monolayer islands of solid phase coexisting with continuous multilayer "reservoirs" of fluid phase adjacent to the air-water interface. Exchange between the monolayer, the multilayer reservoir, and the subphase determines surfactant mechanical properties such a...

The main goal of this paper is to use the multilayer perceptron neural network to suggest a 3D cube of the Total Organic Caron (TOC) in the lower Barnett shale gas reservoir. 3D Poststack seismic data recorded near two horizontal wells drilled in the lower Barnett formation are used as an input to train the neural machine, while the calculated acoustic impedance from sonic and density well-logs...

In this report, we developed a new recurrent neural network toolbox, including the recurrent multilayer perceptron structure and its companying extended Kalman filter based training algorithms: BPTT-GEKF and BPTT-DEKF. Besides, we also constructed programs for designing echo state network with single reservoir, together with the offline linear regression based training algorithm. We name this t...

We introduce a supervised learning algorithm for multilayer spiking neural networks. The algorithm overcomes a limitation of existing learning algorithms: it can be applied to neurons firing multiple spikes in artificial neural networks with hidden layers. It can also, in principle, be used with any linearizable neuron model and allows different coding schemes of spike train patterns. The algor...

In this study, a multilayer gas hydrate reservoir model was implemented based on the geological conditions of Shenhu area in South China Sea (SHCS) to predict production performance during long-term depressurization. Hydraulic fracturing technology introduced boost production, and its positive/negative impact behavior evaluated. Results show that dissociation is severely constrained by pressure...

Hydroelectric power plants’ operational decisions are associated with several factors, such as generation planning, water availability and dam safety. One major challenge is to control the spillage from reservoir. Although this action represents a loss of energy production, it powerful strategy regulate reservoir level, ensuring dam’s The decision use must be made in advance based on level dema...

CoFe/Cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. Nanowires with 30 nm diameter and the definite lengths were obtained. The effect of CoFe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. The layers thickness was controlled t...
