This paper studies the strength and stiffness of rigid polyurethane foam core/glass fabric reinforced-epoxy based -sandwich composites with design optimization in mind. This investigation uses finite element software ANSYS™, an experimental hand lay up technique and mechanical testing in a Universal Testing Machine. The finite element results were compared with results from experimental work that were obtained for flexural strength and flexural rigidity. Testing and analyses were carried out keeping the existing ASTM standard guidelines in mind and design optimization as a study.

Natural Language Processing (NLP) involves many phases of which the significant one is Word-sense disambiguation (WSD). WSD includes the techniques of identifying a suitable meaning of words and sentences in a particular context by applying various computational procedures. WSD is an Artificial Intelligence problem that needs resolution for ambiguity of words. WSD is essential for many NLP applications like Machine Translation, Information Retrieval, Information Extraction and for many others. The WSD techniques are mainly categorized into knowledge-based approaches, Machine Learning based approaches and hybrid approaches. The assessment of WSD systems is discussed in this study and it includes comparisons of different WSD approaches in the context of Indian languages. © 2015 IEEE.

Almost undoubtedly, the greatest invention of the 20th century has been the computer. The computer uses several auxiliary devices to establish a seamless interaction with the user. One challenge faced during the development of these devices, was the lack of direct interfacing between the machine and the user. Today we see Natural User Interfaces (NUI), which include touch activated and speech activated inputs. One problem faced with the touch NUI's is ambiguity. This is mainly due to variations in finger size, proximity of icons, and the fact that the imprint of the finger, called a fingertip blob, may have to be mapped to a single pixel. In this paper we attempt to address the above problems, by focusing on achieving a high level of accuracy at low costs, utilizing image processing techniques, all the while keeping the process simple and fast. A novel algorithm for the same has also been discussed. The algorithm was implemented using the Java programming language on the Java Software Development Kit (JDK) version 1.5.0 (update 22). An accuracy of 100% in fingertip blob detection was achieved and an improvement of 15% was achieved in terms of execution time in comparison with existing algorithms, for various experiments conducted utilizing the new algorithm. © 2012 IEEE.

Public key cryptosystem or the asymmetric crypto system is more secure than secret key method because of a pair of related keys used by both sender and receiver. The problem in most of the cryptosystem is that the plain text is considered as an integer number that leads poor security. In this paper we propose an efficient Bezier curve based public key cryptography technique over Galois field GF(pm), where p=2,3,5,7. Here the plaint text is considered as a (x, y) coordinate over curve elements. © 2014 IEEE.

In India, fluoride is the major inorganic pollutant of natural origin found in groundwater. Fluoride pollution occurs due to natural and manmade reasons and high concentrations have a detrimental effect on health. Electrochemical techniques like Electrocoagulation(EC) appears to be one of the most effective approaches for treatment of water and wastewater because of its versatility, safety, selectivity, amenability to automation and environmental compatibility. Results show that the percentage removal of fluoride was around 94 to 96% for monopolar and bipolar electrodes. Adsorbents like tricalcium phosphate and activated alumina used along with electrocoagulation process also gave promising results. © 2013 CAFET-INNOVA TECHNICAL SOCIETY.
