the main purpose of this investigation is to study the effect of near miscible co2 injection in different porous mediums on both lab and field scales. this effect can be traced by the change of two-phase gas-oil relative permeability curves. in this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...

We have developed a new framework for scale invariant texture analysis using multi-scale local autocorrelation features. The multiscale features are made of concatenated feature vectors of different scales, which are calculated from higher-order local autocorrelation functions. To classify different types of textures among the given test images, a linear discriminant classifier (LDA) is employe...

background with the integration of the evaluation of patient satisfaction in the overall assessment of healthcare services, authorities can be assured about the alignment of these services with patient needs and the suitability of care provided at the local level. objectives this study was conducted in 2013 in zahedan, iran, in order to assess the psychometric properties of the iranian version ...

In this paper, area preserving multi-scale representations of planar curves are described. This allows smoothing without shrinkage at the same time preserving all the scale-space properties. The representations are obtained deforming the curve via geometric heat flows while simultaneously magnifying the plane by a homethety which keeps the enclosed area constant. When the Euclidean geometric he...

We present a novel approach for detection of tubular objects in medical images. Conventional tube detection / lineness filters make use of local derivatives at multiple scales using a linear scale space; however, using a linear scale space may result in an undesired diffusion of nearby structures into one another and this leads to problems such as detection of two tangenting tubes as one single...

objective: evaluation and diagnosis are determinants of treatment outcome; therefore, diagnostic tools should be accurate. the purpose of the present research is construction and norm-finding of a rating scale for the diagnosis of attention deficit hyperactivity disorder (adhd). method: a checklist based on behavioral symptoms of adhd from clinical sources was constructed, based on interview wi...

conclusions this study has provided some preliminary evidence of the reliability and validity of the persian version of rcas when used with family caregivers of older adults with dementia. background caregivers’ self-assessments of the care they provide are the main vehicles that help explore their experiences and are thought to have a major role in care outcomes. the rising number of people wi...
