Granulometric dynamics of the coastal sediments of the Central West coast of India: Insight into morpho-tectonic influences on the beach processes

Abstract: Beach morphologies, primarily include shape, surface changes/variation, and beach volume along with slope, are very dynamic and believed to be largely controlled by waves and currents (Komar, 1998). Contrary to this general notion, results presented in this paper suggest a strong control of the local morpho-tectonic frame-work on foreshore sedimentation. In the 20 km long study area between Bhatkal on the north and Uppunda in the south, foreshore morphology range from reflective and dissipative to intermediate types, but nearshore hydrodynamic regime is similar. The inland morpho-tectonic frame-work reveals graben and horst-like structures. The foreshores bordering these grabens and horsts are dissipative and reflective respectively, have distinctly different granulometric dynamics and sedimentation processes, whereas an intermediate type between the dissipative and the reflective show a large seasonal variability in terms of beach width and slope. The foreshore profile modification indicated that the reflective beaches remained reflective and the dissipative beaches remained dissipative throughout the year, despite the large variation in the wave energy condition from monsoon through post-monsoon to pre-monsoon. Spit growth is observed only in the dissipative beach. Granulometric dynamics in all the three types of beaches show distinct differences. The reflective beaches show significant fluvial characteristics of sediments in all the seasons, dissipative beaches show minor fluvial characteristics and the intermediate beaches show significant fluvial characteristics only during the monsoon seasons. Sediment transport process in the reflective beaches is dominantly by rolling process, in the dissipative beaches suspension is the dominant mechanism, and in the intermediate type beaches a large range from suspension to rolling is observed. Sediments in the beaches are negatively skewed through symmetrical to positively skewed in reflective beaches, while in dissipative beach negative skewness is dominant. Integration of the tectonic framework, beach morphology and granulometric dynamics suggest that temporal and spatial variations in textural characteristics are related to a strong morpho-tectonic control rather than seasonal variations in wave energy condition.

On the visco-elastic and dielectric behaviour of two alcohols and their binary mixture

Abstract: Inter-molecular and intra-molecular interactions in liquids determine the physical properties of the systems. These interactions are understood through the measurement of these physical properties. These become especially important in the case of alcohols in view of the specific type of interactions involved. Study of the variation of dielectric relaxation time with the viscosity of the medium is relevant in drawing certain quantitative conclusions regarding molecular motion and the inter-molecular forces in liquids, liquid mixtures, dilute solutions and multi-component polar solutes in dilute solution. In the absence of a perfect empirical or theoretical equation for the variation of dielectric relaxation time with viscosity, the experimental investigations on different systems can only give an insight. In the present study, the results of dielectric measurements carried out on pure samples of methyl alcohol and propyl alcohol in dilute solutions in different mixed solvents (benzene + paraffin) and on bi...

Neuro-fuzzy fusion in a multimodal face recognition using PCA, ICA and SIFT

Abstract: Face recognition has been widely used in much real-time application for biometric authentication. This paper is discussed with the implementation of multimodal face recognition with neuro-fuzzy fusion. We used principal component analysis, independent component analysis and scale invariant feature transform for feature extraction and result are fused with neuro fuzzy inference system to obtain the recognition ID. PCA is the statistical method for face recognition under the enormous subject of 'factor analysis'. This unsupervised method for a set of reference images represents faces as linear combination. The generalised expression independent component analysis can treat pixels as observations and images at random variables or vice versa. Another method considered is scale invariant feature transform that scales histogram orientation for dominant feature determination invariant to illumination, rotation and is robust against considerable amount of noise. This research studies the performance evaluation of recognition method constructed in union with neuro fuzzy inference system employing PCA, ICA and SIFT.

Performance analysis of source coding techniques

Abstract: In this paper the performance of different source coding techniques is analyzed by considering same set of probabilities for all the algorithms for binary, tertiary and quarternary The algorithms used are Shannon, Shannon Fano and Huffman coding algorithms Performance of these algorithms is analyzed in terms of average length, entropy and efficiency

Innovative workflow for accreditation process to ensure quality engineering education in India

Abstract: Engineering education has become a main attraction, contributing to the global industry revolution and in particular to Indian economy. The exponential growth in technical education has, however, not translated into any significant growth in the number of quality graduates acceptable to industry, due to insufficient availability of qualified faculty, teaching methodology, evaluation techniques and processes. Increasing autonomous institutions projecting their institution is another mask to underlying quality of education and evaluation procedures, which is supposed to be measured on the common scale and platform. The heterogeneity in curriculum, varied infrastructure and quality of faculty in-terms of competency and ability to make difference in learning process towards making students ready for industry and higher education and research, is posing yet another problem for the accreditation bodies. Today accreditation bodies lack in-terms of: equity in evaluation rigor, quick response, flexibility and ease of operation and access, prevention of academic fraud and participation of universities.
