Abstract: Abstract - Fingerprint enhancement is a critical step in fingerprint identification. Most of the existing enhancement algorithms are based on the local ridge direction. Existing methods can be improve d the clarity of the ridge and valley structures of input fingerprint image based on the estimated local ridge orientation and frequency. In this proposed method a better enhancement is achieved using a noise cancelation scheme which includes variance stabilizing Transformation (Anscombe Transform), Fuzzy filter and Curvelet transform. Fingerprint enhancement is done using Gabor based ridge enhancement. This algorithm has improved performance in goodness index of the extracted minutiae and the accuracy of an online fingerprint verification system.

Title: THE RELATIONSHIP BETWEEN THE USE OF GIS AND CONSTRUCTION PROJECT SUCCESS
Author: Hamad Ahmed Altuwaijri
Keyword: GIS, Construction Projects, geocoding process
Page No: 104-115
Abstract: This survey research effort investigated the relationship between 11 selected Geographic Information System (GIS) functions and three (time, cost, and quality) highway and transportation construction -project success criteria. The population included engineers and information technology professionals in the United States who worked in the highway and transportation area. No significant relationship between GIS function use and construction project success criteria (time and cost) was found. The third success criterion (customer’s specification?quality) was not tested because of the lack of variability of the responses. There were significant differences between organizations that focused on highway, street, road, and public sidewalk jobs and other construction organizations that focused on different construction jobs as related to the following two GIS functions: Terrain Modeling and Traffic Management. Some functions that were very close to the .05 level of significance included Estimating Project Costs, Terrain Analysis, 2D and 3D Visualization, and Route/Site Selection. Recommendations included the following: (a) Engineers and managers should consider using GIS functions for highways, streets, roads, or public sidewalk projects; (b) Special attention should be given to ensuring that appropriate GIS training is provided for all levels in the organization.

Abstract: In human speech one of the key aspects is its Formant structure. Formants are resonances of the vocal tract, and as such they have a close relation to the vocal tract geometry. In other words Formant frequency may be refers to the spectral peak of the sound spectrum. Generally, for perception and discrimination three formants namely First (F1), Second (F2) and Third (F3) are considered. In this paper, the formant frequency of Assamese vowels and words of typical structure i.e. CV, CVC, VCV are estimated which can be helpful for developing Assamese Automatic Speech recognition (ASR) system. In this study, we design a database which consist of eight Assamese vowels and words of 5 from each structure total 15 words uttered by 5 times which make our database having total 115 samples. In this study we have analyze the sample for F1, F2 and F3 formant frequencies. It is observed that a significant variation is present in the formant frequencies with respect to gender for both phoneme set as well as the word set.
