THE PERFORMANCE ANALYSIS OF AN AKF BASED TIGHTLY-COUPLED INS/GPS INTEGRATED POSITIONING AND ORIENTATION SCHEME WITH ODOMETER AND NON-HOLONOMIC CONSTRAINTS
INS GPS Tightly-coupled AKF non-holonomic constraints
2014/4/29
INS/GPS integration scheme can overcome the shortcoming of GPS or INS alone to provide superior performance, thus this study implements a tightly-coupled INS/GPS integration scheme using AKF as the co...
Safety constraints applied to an adaptive Bayesian condition-based maintenance optimization model
Bayesian reliability Adaptive maintenance optimization model Safety constraint
2012/4/15
A model is described that determines an optimal inspection and maintenance scheme for a deteriorating unit with a stochastic degradation process with independent and stationary increments and for whic...
A CART technique to adjust production from longwall coal operations under ventilation constraints
Mining safety Coal mine methane Methane emissions Longwall mines CART analyses
2012/4/14
Methane emissions in longwall coal mines can arise from a variety of geologic and production factors, where ventilation and degasification are primary control measures to prevent excessive methane lev...
VALIDATION OF GEOGRAPHICAL DATASETS AGAINST SPATIAL CONSTRAINTS AT CONCEPTUAL LEVEL
Conceptual Modelling of Spatial Databases, Spatial Integrity Constraints Spatial Data Validation Model-Driven Architecture Geographical Applications Spatial Data Infrastructures
2014/5/9
A huge amount of geographical datasets are becoming available in distributed environments like Spatial Data Infrastructures (SDI). These datasets are very heterogeneous since they come from different ...
Fourier Descriptors with Different Shape Signatures: a Comparative Study for Shape Based Retrieval of Kinematic Constraints
Fourier Descriptors Kinematic Constraints Shape Based Retrieval
2011/8/5
Fourier Descriptors (FD) has been widely used in image analysis and computer vision for shape recognition as they can be made independent of translation, rotation, as well as scaling. They have also b...
Provisioning Schemes Accounting for ROADM Add/Drop Constraints in GMPLS-based WSON
Provisioning Schemes Accounting ROADM Add/Drop Constraints GMPLS-based WSON
2015/5/21
Provisioning schemes exploiting the recently introduced GMPLS extensions for add/drop in WSONs are proposed to effectively handle different ROADM structures and provide a preference on the utilization...
Heuristic Resource Provisioning for Dynamic Wavelength Services with Access Port Constraints
Heuristic Resource Provisioning Dynamic Wavelength Services Access Port Constraints
2015/5/21
This paper introduces a fast heuristic resource provisioning algorithm for dynamic wavelength services on agile reconfigurable ROADM networks on which customer connections are only constrained by acce...
Impact of transparent network constraints on capacity gain of elastic channel spacing
network constraints channel spacing capacity gain
2015/5/15
We compare fixed-grid network architectures with variable-spacing OFDM based solutions. We show that capacity gains can reach up to 50% but are strongly affected by physical and topological constraint...
Constraints on two-neutron separation energy in the Borromean $^{22}$C nucleus
Binding energies Faddeev equation Three-body
2011/10/11
Abstract: The recently extracted matter radius of carbon isotope $^{22}$C allows us to estimate the mean-square distance of a halo neutron with respect to the center-of-mass of this nucleus. By consid...
Filters and Ultrafilters as Approximate Solutions in the Attainability Problems with Constraints of Asymptotic Character
Control problems Ultrafilters Topology
2013/1/29
Abstract problems about attainability in topological spaces are considered. Some nonsequential version of the Warga approximate solutions is investigated: we use filters and ultrafilters of measurable...

Islets Constraints Bidirectional Search Delaunay Triangulation
2013/1/29
Aiming at Delaunay triangulation with islets constrains in terrain simulation. A general Delaunay triangulation algorithm for constrained data set with islets is proposed. The algorithm firstly constr...
LOCALITY PRESERVING CONSTRAINTS FOR SUPER-RESOLUTION WITH NEIGHBOR EMBEDDING
Super-resolution Neighbor embedding Manifold assumption Locality preserving constraints
2013/7/16
In this paper, we revisit the manifold assumption which has been widely adopted in the learning-based image superresolution. The assumption states that point-pairs from the high-resolution manifold sh...
