the perception of hospiyal inpatients from current status and expectation status of observance about patient’s rights
Infant psychology has heavily drawn on the Violation-of-Expectation (VoE) method. In this piece, I analyse assumptions that go into VoE method by comparing it with other looking time measures. Reviewing key arguments in literature, argue relies too many questionable assumptions, its conceptual foundations are thin, and findings empirically not conclusive. Theoretical inferences based thus specu...
Abstract Digital rock is an emerging area of physics, which involves scanning reservoir rocks using X-ray micro computed tomography (XCT) scanners and it for various petrophysical computations evaluations. The acquired CT projections are used to reconstruct the attenuation maps rock. image reconstruction problem can be solved by utilization analytical (such as Feldkamp–Davis–Kress (FDK) algorit...
The reconstruction of sparse signal is an active area research. Different from a typical i.i.d. assumption, this paper considers non-independent prior group structure. For more practical setup, we propose EM-aided HyGEC, new algorithm to address the stability issue and hyper-parameter facing other algorithms. instability problem results ill condition transform matrix, while unavailability hyper...
BACKGROUND Generally, attenuation correction is made by incorporating a linear attenuation coefficient, which is based on the attenuation coefficient map (mu-map) created from a computed tomography scan, into the ordered subsets-expectation maximization reconstruction method in non-uniform domains. A non-uniform Chang's attenuation correction method that uses the mu-map created from a computed ...
