In [4], given a binary 26-adjacency voxel-based digital volume V , the homological information (that related to n-dimensional holes: connected components, ”tunnels” and cavities) is extracted from a linear map (called homology gradient vector field) acting on a polyhedral cell complex P (V ) homologically equivalent to V . We develop here an alternative way for constructing P (V ) based on homo...

A perfect (t, w, v; m)-threshold scheme is a type of combinatorial design that provides a way of distributing partial information (chosen from a set of v points called shadows) to w participants, so that any t of them can easily calculate one of m possible keys, but no subset of fewer than t participants can determine any partial information regarding the key. In this paper, we give a survey of...

One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...

Background and Importance: Our learning curve during two decades of neurosurgical practice has been changed from an abstractive to a more meaningful and conductive state. In cases of fifth nerve neurinoma, pre-operative anatomopathologic diagnosis could lead us to a pre-planned program during and after the surgery to get the safe surgical result. Case Presentation: Representation of two comp...

which is extremely strange the first time one encounters it. After all, why not just write V (x, y) = ye1 − xe2 where e1 = (1, 0), e2 = (0, 1)? What do partial derivatives have to do with anything? (That was the question I asked.) However, if viewed in the right way, it is not so strange. For if a vector field V is given, then one natural thing that can be done with it is to differentiate a sca...

OBJECTIVE To compare empirical probability plots in patients with glaucoma for size V and III perimetry testing. METHODS We computed empirical probability plot percentile limits after testing 60 age-matched controls tested with both size III (Swedish interactive thresholding algorithm) and size V (full threshold) perimetry twice. Probability plots of 120 patients with glaucoma tested in the s...

This study was designed to investigate the benefit of inclusion of various verbal elements in 3D talking-head on pronunciation learning among non-native speakers. In particular, the study examines the effects of three different multimedia presentation strategies in 3D talking-head Mobile-Assisted-Language-Learning (MALL) on the learning achievement of students with low English pronunciation ski...

This paper presents the results of a study of Australian winery websites over a five year period. The research sets out to determine if Australian winery websites have matured and increased in content and functionality since 2003. Data collected in 2003 and 2007 have been analysed to determine if Australian winery websites have significantly changed to provide more to satisfy customer requireme...

Studying the effects of one-way variation of any number of parameters on any number of output probabilities quickly becomes infeasible in practice, especially if various evidence profiles are to be taken into consideration. To provide for identifying the parameters that have a potentially large effect prior to actually performing the analysis, we need properties of sensitivity functions that ar...
