Fayyad and Uthursamy (2002) have stated that the majority of the work (representing months or years) in creating a data warehouse is in cleaning up duplicates and resolving other anomalies. This article provides an overview of two methods for improving quality. The first is data cleaning for finding duplicates within files or across files. The second is edit/imputation for maintaining business ...

A modified technique for the Winkler determination of dissolved oxygen has been used at the Chesapeake Bay Institute for several years. The modifications result in increased simplicity and speed and reduction in the errors due to manipulation. The unusual features of the technique are the elimination of the volumetric transfer of the final iodine solution and the reagent concentrations. The sou...

Loglinear modeling methods have become quite straightforward to apply to discrete data X. The models for missing data involve minor extensions of hot-deck methods (Little and Rubin 2002). Edits are structural zeros that forbid certain patterns. Winkler (2003) provided the theory for connecting edit with imputation. In this paper, we give methods and algorithms for modeling/edit/imputation under...

This paper presents three novel approaches of text steganography. The first approach uses the theme of missing letter puzzle where each character of message is hidden by missing one or more letters in a word of cover. The average Jaro score was found to be 0.95 indicating closer similarity between cover and stego file. The second approach hides a message in a wordlist where ASCII value of embed...

Abstract A challenging task in nonlocal continuum mechanics consists formulating constitutive relations leading to well-posed structural problems. Several strategies have been adopted overcome issues inherent applicability of Eringen’s pure theory nanostructures, such as local/nonlocal mixtures elasticity and integral models involving modified averaging kernels. These can be applied the ill-pos...

Review of WINKLER, Martin. Ovid on Screen. A Montage Attractions. Cambridge: Cambridge University Press, 2020. 444 p.

As known, in a Winkler type of analysis the soil medium underneath foundation is violently replaced by row parallel springs having constant ks. For effective calculation latter, which called modulus subgrade reaction, two elastic constants (the modulus, E and Poisson’s ratio, ν) must be known. Although for homogenous soils this generally seems not to problem, same does stand stratified mediums ...
