A variational formulation of vertical slice models [PDF]

, 2013
A variational framework is defined for vertical slice models with three-dimensional velocity depending only on x and z. The models that result from this framework are Hamiltonian, and have a Kelvin–Noether circulation theorem that results in a conserved ...

On the Estimation of Forest Vertical Structure From Multibaseline Polarimetric SAR Data [PDF]

, 2012
Forest characterization and biomass estimation by means of remote sensing systems are nowadays “hot topics” within the remote sensing community, given their importance in the terrestrial carbon budget. In fact, forest vertical structure is a key variable

Layered to Clean Vertical Slice Architecture

, 2022
Good software architecture should minimize the resources needed to build, maintain, and deploy an application. Choosing the right design for a specific problem should result in nearly constant overhead in maintaining and extending the system through its ...

Propagator and wave-equation inversion for near-receiver material properties [PDF]

, 2004
Near-receiver material properties are required for the separation of the recorded wavefield into upgoing and downgoing P and S waves, and are also important for static time-shift corrections.

Monitoring the sea environment using acoustics the role of the acoustical observatories [PDF]

, 2013
The presentation deals with theoretical factors and technical specifications pertinent to the design of an acoustical observatory for the monitoring of the marine environment. Two types of observatories are mentioned, namely active and passive. Among the

Analogue Modelling of Inverted Oblique Rift Systems [PDF]

, 2005
The geometric evolution of brittle fault systems in inverted oblique and offset rift systems has been simulated using scaled sandbox analogue models. Dry fine-grained quartz sand was used to represent the brittle upper crust.

Mesenchymal Stem Cells Promote Oligodendroglial Differentiation in Hippocampal Slice Cultures [PDF]

, 2009
We have previously shown that soluble factors derived from mesenchymal stem cells (MSCs) induce oligodendrogenic fate and differentiation in adult rat neural progenitors (NPCs) in vitro.

Cross-Validation, Support Vector Machines and Slice Models [PDF]

, 2001
We show how to implement the cross-validation technique used in ma- chine learning as a slice model. We describe the formulation in terms of support vector machines and extend the GAMS/DEA interface to allow for e cient solu- tions of linear, mixed ...
