Mapping ontologies is a crucial process when facilitating system interoperability and information exchange. Ontology Mapping systems commonly utilize string metrics in the mapping process to compare concept names. String metrics can be extended using the Winkler method, which increases the similarity value of two strings if these have a common prefix. A common occurrence for two corresponding o...

A recently published revision of the absorption cocfficienLs for oxygen in water has prompted a reinvestigation of the subject by a new microgasometric technique. A known volume of gas-free water (approximately 1 ml) was brought into contact with oxygen at constant pressure and temperature. The oxygen uptake and the amount of water were measured with a micrometer burette. The results obtained a...

Abstract Variational principles and variationally consistent boundary conditions are derived for a system of double Rayleigh beams undergoing vibrations subject to axial loads. The elastic layer connecting the modelled as three-parameter nonlinear Winkler–Pasternak with Winkler having linear components Pasternak only component. forced freely vibrating beam using semi-inverse approach. Hamilton’...

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...
