Imaging Deep Gas Prospects with Multi-component Seismic Data
Multi-component Seismic Data Gas producers across the Gulf of Mexico are targeting deeper and deeper drilling objectives. Most operators in the Gulf consider 30,000ft to be the deepest target depth that will be drilled for the next few years. To image geology at those depths, seismic reflection data must be acquired with offsets of at least 30,000ft. TECHNOLOGY DEVELOPMENTS IN NATURAL GAS EXPLO...
متن کاملJoint reconstruction of simultaneously acquired MR-PET data with multi sensor compressed sensing based on a joint sparsity constraint
Bernard & Irene Schwartz Center for Biomedical Imaging, Department of Radiology, NYU School of Medicine, New York, New York, USA State-of-the-art MR-PET scanners allow simultaneous data acquisition. However, image reconstruction is performed separately and results are only combined at the visualization stage. PET images are reconstructed using a variant of EM and MR data are reconstructed using...
متن کاملDistributed Unmixing of Hyperspectral Data With Sparsity Constraint
Spectral unmixing (SU) is a data processing problem in hyperspectral remote sensing. The significant challenge in the SU problem is how to identify endmembers and their weights, accurately. For estimation of signature and fractional abundance matrices in a blind problem, nonnegative matrix factorization (NMF) and its developments are used widely in the SU problem. One of the constraints which w...
متن کاملsingle-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولSparsity regularization for image reconstruction with Poisson data
This work investigates three penalized-likelihood expectation maximization (EM) algorithms for image reconstruction with Poisson data where the images are known a priori to be sparse in the space domain. The penalty functions considered are the 1 norm, the 0 “norm,” and a penalty function based on the sum of logarithms of pixel values, R(x) = ∑np j=1 log (xj δ + 1 ) . Our results show that the ...
