This article proposes a solution of the Lambertian Shape From Shading (SFS) problem by designing a new mathematical framework based on the notion of viscosity solutions. The power of our approach is twofolds: 1) it defines a notion of weak solutions (in the viscosity sense) which does not necessarily require boundary data. Note that, in the previous SFS work of Rouy et al. [23, 15], Falcone et ...

This paper describes an automatic feature selection algorithm integrated into a classification framework developed to discriminate between sleep and wake states during the night. The feature selection algorithm proposed in this paper uses the Mahalanobis distance and the Spearman’s ranked-order correlation as selection criteria to restrict search in a large feature space. The algorithm was test...

In this paper, we present a new neural network (NN) for three-dimensional (3D) shape reconstruction. This NN provides an analytic mapping of an initial 3D polyhedral model into its projection depth images. Through this analytic mapping, the NN can analytically refine vertices position of the model using error back-propagation learning. This learning is based on shape-from-shading (SFS) depth ma...

Herein, hydroxypropyl-beta-cyclodextrin (HPβCD) inclusion complex (IC) of a hydrophobic drug, sulfisoxazole (SFS) was incorporated in hydroxypropyl cellulose (HPC) nanofibers (HPC/SFS/HPβCD-IC-NF) via electrospinning. SFS/HPβCD-IC was characterized by DSC to investigate the formation of inclusion complex and the stoichiometry of the complex was determined by Job's plot. Modeling studies were al...

A new method is described Struct we from Symmetry (SFS) in which objects possessing bilateral symmetry may be reconstructed from a single perspective view. The algorithm exploits the groundplane constraint [9, 14] and assumes a camera model, to allow 3D recovery up to scale. The SFS algorithm has been implemented in the form of an interactive tool. The user marks a set of symmetric object point...

We present a multiview method for the computation of object shape and re ectance characteristics based on the in tegration of shape from shading SFS and stereo for non constant albedo and non uniformly Lambertian surfaces First we perform stereo tting on the input stereo pairs or image sequences When the images are uncalibrated we recover the camera parameters using bundle adjustment Based on t...

General genealogical processes such as Λ- and Ξ-coalescents, which respectively model multiple and simultaneous mergers, have important applications in studying marine species, strong positive selection, recurrent selective sweeps, strong bottlenecks, large sample sizes, and so on. Recently, there has been significant progress in developing useful inference tools for such general models. In par...

OBJECTIVE The aim of this study was to investigate the concentrations of T cell derived cytokines in the synovial fluids (SFs) of patients with psoriatic arthritis (PsA) in comparison with rheumatoid arthritis (RA) and osteoarthritis (OA). METHODS Th1 type cytokines (interleukin 2 (IL2), tumour necrosis factor beta (TNF beta), and interferon gamma (INF gamma) and Th2 type cytokines (IL4, IL10...

Network Function Virtualization (NFV), network slicing, and Software-Defined Networking (SDN) are the key enablers of fifth generation mobile networks (5G). Service Chaining (SFC) plays a critical role in delivering sophisticated service per slice enables traffic traversal through set ordered Functions (SFs). In fully symmetric SFCs, uplink downlink traverse same SFs, while asymmetric SFC, reve...

Supplier selection process plays a vital role in supply chain management and is the most important variable its success. With increasing environmental considerations, organizations must consider sustainability considerations economic goals to protect environment. Furthermore, destructive effects of disruptions on performance companies have prompted organizational experts pay special attention c...
