Abstract

Character recognition plays an important role in the field of pattern recognition. Offline character recognition methodology mainly focuses on recognizing the characters irrespective of the difficulties that may arise due to the variations in writing style. This writing style becomes more complex when the characters are in curvy structure. The proposed recognition methodology was applied on one of the complex structures of south Indian language 'Tamil'. The novelty behind this process lies on the selection and extraction of the feature sets. Zoning and Chain Code procedures are employed here to select the features and Sub Line Direction and Bounding box algorithms are used for extracting the features. In order to achieve a better recognition rate, a learning algorithm, Support Vector Machine (SVM) has been implemented. These concepts are experimented on 30 Tamil character sets (Vowels and Consonants) and achieved an accuracy rate of 88%.

Abstract

Background/Objectives: The experimental investigations are carried out to study the behaviour of Glass Fiber Reinforced Polymer (GFRP) sheet not wrapped and wrapped around RC column. Methods/Statistical analysis: Strength of the RC column was assessed by performing compressive and split tensile strength tests at the interval of 7, 14, and 28 days as per code of provision. Findings: In this study, the recycled aggregate has been replaced with the natural aggregate. The replacement percentage was chosen for this study was 10%, 20%, 30%, 40%, and 50%. The compressive strength of partial replacement of recycled coarse aggregates (PRRCA) are found to be higher than the compressive strength of normal concrete. Furthermore, results on load, deflection and failure modes of each of the columns were also obtained. Applications/Improvements: Strength of the damanged concrete structures can be improved after wrapping GFRP sheet over the damaged structures.
