Purpose This is a general review study aiming to specify the key customer-based factors and technologies that influence value co-creation (VCC) process through artificial intelligence (AI) automation in hospitality tourism industry. Design/methodology/approach The uses theory-based literature approach explore influencing VCC By reviewing relevant literature, authors conclude theoretical framewo...

The complexity class CC is defined as the set of problems AC0 reducible to the comparator circuit value problem. Subramanian proved that several other problems are complete for CC, including the stable marriage problem, and finding the lexicographical first maximal matching in a bipartite graph. We introduce a two-sorted theory VCC for CC. We simplify Subramanian’s completeness proofs for the a...

Let G be a simple graph on vert ices having a maximum matching M. The deficiency def(G) of G is the number of M-unsaturated vertices in G. The vertex clique covering number vcc(G) of G is the smallest number of cliques (complete subgraphs) needed to cover the vertex set of G. In this determine def(G) and vcc(G) for the case when G is a tree with each vertex having degree 1 or k.

The Virtual Camera Composition (VCC) problem consists in automatically positioning a camera in a virtual world, such that the resulting image satisfies a set of visual cinematographic properties [3]. In this paper, we propose an approach to VCC based on Particle Swarm Optimization [5]. We show, in realistic situations, that our approach outperforms a discretized, exhaustive search method simila...

In this study, vanadium conversion coating(VCC) was deposited on the surface of soft-cast steel (St-37).  A thermoset coating was enforced on the VCC and blank substrates. The surface was characterized by field emission scanning electron microscope (FE-SEM), elemental mapping of energy dispersive X-ray (EDX) and atomic force microscopy (AFM). The adhesion strength...

The physical mechanisms driving star formation (SF) in galaxies are still not fully understood. Tidal dwarf galaxies (TDGs), made of gas ejected during galaxy interactions, seem to be devoid of dark matter and have a near-solar metallicity. The latter makes it possible to study molecular gas and its link to SF using standard tracers (CO, dust) in a peculiar environment. We present a detailed st...

PURPOSE To evaluate the birefringence properties of eyes with age-related macular degeneration (AMD). To compare the information from two techniques--scanning laser polarimetry (GDx) and polarization-sensitive spectral-domain optical coherence tomography (OCT)--and investigate how they complement each other. METHODS The authors prospectively examined the eyes of two healthy subjects and 13 pa...

PURPOSE In scanning laser polarimetry with variable corneal compensation (SLP-VCC), the macula is used as an intraocular polarimeter to calculate and neutralize corneal birefringence based on an intact Henle's layer. The purpose of this investigation was to validate this strategy in eyes with macular structural disease. METHODS A nerve fiber analyzer was modified to enable the measurement of ...

OBJECTIVE To compare the ability of scanning laser polarimetry (SLP) to discriminate between healthy and glaucomatous eyes with manufacturer-assumed fixed and subject-specific variable corneal polarization magnitude (CPM) and corneal polarization axis (CPA) values. METHODS An SLP was modified to enable the measurement of CPM and CPA values so that compensation for corneal birefringence could ...

The purpose of this study was to evaluate the efficacy of three screening tests in detecting glaucoma in its early stage: the Tendency Oriented Perimetry (TOP) and Frequency Doubling Perimetry (FDP) visual field tests, and the Glaucoma Diagnostic (GDx) nerve fibre layer analyser. Eighteen patients with glaucoma who showed an early defect on HFA c 24-2 and twenty normals underwent the three test...
