Visualization of News Feed Data using Lexicon-based Approach

Abstract: Presently these days people enjoy reading online news articles. The news articles come from long range informal communication destinations. The issue with the news articles in the online networking sites is that we can't decide whether the news is genuine or counterfeit. We apply different techniques to determine the extremity of the news article. The extremity of the article is calculated using the lexicon-based approaches. We utilize the assumption score to decide the extremity and arrange the news articles as genuine, phony or nonpartisan. Thusly, opinion examination of online networking substance might be of enthusiasm for various associations, particularly in security and law implementation segments. This paper displays another dictionary based notion investigation calculation that has been planned with the fundamental spotlight on-going Twitter content examination.

Structural (Shape) Feature Extraction for Ear Biometric System

Abstract: The Ear Biometrics is an emerging modern human identification system, which is a passive biometrics system where the recognition of an individual is done without the knowledge of the human subject. This kind of passive biometrics system can help the image analyst to extract useful information feature for public surveillance system. The proposed article extracts structure (shape) features such as Area, Perimeter, Eccentricity, Elongation, Compactness, Horizontal Height, Vertical Height, Major Axis, Minor Axis, Circularity and Rectangularity of the human ear to construct an effective ear biometrics system.

Thermal Comfort Studies of Residential Building Models in Vijayawada

Abstract: Brick masonry wall is the more common walling system being used in residential buildings. As the demand for housing is increasing, new construction materials are coming up in the market and being utilized in the construction. Solid concrete blocks (SCB) and autoclave aerated concrete (AAC) blocks are the two materials which are most commonly used in most of the construction sites apart from the clay bricks (CB). The thermal behaviour of the buildings with these materials needs to be studied. It is also necessary to reduce the heat inside the building to improve the human comfort. Effect of coating material over roof also needs to be studied. Living comfort inside any building mainly depends on the “thermal comfort”. Thermal comfort mainly involves the interior conditions of the rooms, i.e. mainly temperature and humidity, maintaining and distributing it evenly, and the quality of air (purity, humidity rate, healthiness). By providing a thermal insulation to all the surfaces combined with seasonal adoption of ventilation, thermal comfort can be achieved in different climate conditions. By keeping these points in a view, a thorough study was conducted to know the thermal variations in various house models by varying the wall type. Results indicated the superior thermal performance of the model with AAC block in comparison with the models made with solid concrete block and clay brick.

Intensifying the Security of Information by the Fusion of Random Substitution Technique and Enhanced DES

Abstract: Information security is the process of defending information from unauthorized access and loss. Nowadays in most of the organizations, information is accessed through online. So there is a need to safeguard the information from attackers and hackers. Cryptography is the method of storing and transmitting data in an unreadable form so that only indented user can read and process it. There are two categories of cryptography: symmetric key and asymmetric key encryption algorithms. Symmetric key algorithms use single key for both encryption and decryption. RC2, RC4, DES, Triple DES, IDEA etc. are some of eminent existing symmetric key algorithms. In this paper, we tried to enhance the security of DES, which is now considered to be insecure for many applications. We tried to provide double security by adding a random substitution technique before applying EDES algorithm where we modified the round function and increased the number of rounds from 16 to 32. The performance of the proposed technique is compared with traditional DES algorithm by means of avalanche effect and plaintext sensitivity.
