The research examined naive user analysts' learning of data analysis skills; namely. (1) the difficulty of learning data analysis, (2) the differential learning rates among development tools, and (3) the dimensions of the tools contributing to the learning differences. A total of fifty-six students participated in two experiments. The experiments involved repeaied trials of practice and feedbac...

Abstract This review paper on groundwater protection measures in South Africa focuses the actual implementation of measures, particular, resource-directed (RDM) as described Chapter 3 National Water Act (NWA). Significant catchment-wide RDM has taken place a phased manner throughout various catchments since 2012. By 2015, approximately R380 million had been expended water resource over period 1...

The paper presents a new method to detect forgery by copy-move, splicing or both in the same image. Multiscale, which limits the computational complexity, is used to check if there is any counterfeit in the image. By applying one-level Discrete Wavelet Transform, the sharped edges, which are traces of cut-paste manipulation, are high frequencies and detected from LH, HL and HH sub-bands. A thre...

The discrete Fourier transform-rational dither modulation (DFT-RDM) has been proposed as a way to provide robustness to linear-time-invariant (LTI) filtering for quantizationbased watermarking systems. This scheme has been proven to provide high rates for white Gaussian hosts but those rates considerably decrease for non-white hosts. In this paper the theoretical analysis of DFT-RDM is generali...

Literature on technology and innovation management has identified the research and development (R&D) and marketing (RDM) interface as a critical organizational complexity that when managed well can affect company success in innovation. Cross-functional teams and collaboration mechanisms, such as boundary spanners, have been identified as solutions to the problems in communication between the tw...

In this article, we will estimate efficiency amountof decision-making unit by offering the continuous piecewise polynomialextrapolation and interpolation by CCR model input-oriented on the assumptionthat it is constant returns to scale in different times. And finally, we willestimate efficiency amount of decision-making unit indifferent times byoffering an example.

We present a text mining approach that discovers patterns at varying degrees of abstraction in a hierarchical fashion. The approach allows for certain degree of approximation in matching patterns, which is necessary to capture non-trivial features in realistic datasets. Due to its nature, we call this approach Recursive Data Mining (RDM). We demonstrate a novel application of RDM to role identi...
