Natural Language Processing Based Sentimental Analysis of Hindi (SAH) Script an Optimization Approach

Abstract: Sentimental analysis is one of the most common applications of Natural Language Processing (NLP). Sentiment analysis, the term itself refers to identify the emotions and opinions of people through written text. It is concerned with information extraction from any text based on the polarity in social behavior whether it may be positive, negative or neutral. This paper presents a practical dynamic approach on to find the polarity of any sentence and analyse the opinion of the particular sentence. The proposed Sentimental Analysis of Hindi (SAH) script have adopted two different classifier Naive Bayes Classifier and Decision Tree Classifier is used for the text extraction. The positive, neutral and negative result validation shows a comparative result of sentimental analysis.

Transient liquid phase bonding of stainless steel 316 L to Ti-6Al-4 V using Cu/Ni multi-interlayer: microstructure, mechanical properties, and fractography

Abstract: In the present work, transient liquid phase bonding (TLP) of stainless steel 316 L to Ti-6Al-4 V using simultaneously both Cu and Ni interlayers was performed and effect of bonding temperature (950 to 1050 °C) on microstructure and mechanical properties of the joints was studied. The joint zones were analyzed using scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). Microhardness and shear strength tests were also applied to evaluate the mechanical properties of the joints. The results showed that various eutectic phases and intermetallic compounds were formed at the interface; however, diversity of intermetallics was different in the joint zone for each specimen which can be due to the bonding temperature and type of eutectic phase transformation. The more increase of bonding temperature to higher than 1000 °C, the more deterioration in mechanical properties of the bonded joints is led so that the shear strength decreased from 385 MPa (maximum value) to 257 MPa.

On Quasisymmetric Space

Abstract: In this paper we introduce quasisymmetric space and examine several topological characteristics of this space and establish common fixed point theorems for four self mappings in quasisymmetric spaces
