 Abstract

Unsustainable industrialization and pollution are having long term effects on our environment. Voluntary methods of environmental performance certification and labelling for textile products and stringent rules on wastewater discharges are forcing textile processors to reuse the discharged water and chemicals. This challenge has provoked the researchers for an intensive research in new advanced treatment technologies, which are currently advancing at a faster pace to full-scale installations. Some of these processes are filtration, chemical oxidation, specialized flocculation techniques, anaerobic digestion, fixed-film bioreactors, and electrolysis and foam flotation. Despite the fact that all of these technologies are economical and efficient, like the two sides of a coin, they are also subject to limitations. Optimisation of reaction parameters was done using repeated applications.

 Abstract

The performance of the best relay selection on Hybrid relay mode in cognitive radio relay networks is studied. Some important factors, such as the bit error ratio (BER), the outage probability, and the average channel capacity, are analyzed in this paper. The impact of spectrum sensing process as well as the spectrum utilization efficiency of primary user on the performance of Hybrid selection-based cognitive radio relay networks is considered. The proposed scheme is validated by simulations by using MATLAB, and the analyses of closed-form expressions for some figures of merit, e.g., the outage probability, the BER, and the average channel capacity, are all consistent with the outcomes of simulations. The simulations also prove that the performance of the proposed scheme is impacted considerably by some other critical parameters, such as the number of relays. In this paper the hybrid decode and forward (DAF) and amplify and forward (AF) using Huffman coding is used for a single relay and multiple relays, the whole arrangement is done in MATLAB environment. It is noticed form the result and discussions that our proposed approach is able to achieve less bit error rates and high capacity to reduce the vulnerabilities in cognitive radio networks (CRN).

 Abstract

Modernism starts with the acceptance of new things in life. It is the age of great reformation at the every stage of life for the people. The Indian Modernism brought by the British. Their policies and tendencies of ruling over India had given birth to the new era. The present article is about the general sense of Modernism and its origin. It shows the gradual growth and development of Modernism.

In data communication, security plays a vital role when transmitting the data packets from one place to another. On the other hand intrusion on the networks makes the data communication vulnerable. MANET is a Mobile Ad hoc Network with wireless nodes that are communicated each other without any predefined infrastructure. Because of dynamic topology the security may very much challenging in MANETs and intrusion detection techniques become wide. The comprehensive analysis of security measures in MANET defines the various techniques that provide the intrusion detection techniques. In this paper we compare the proposed decision tree based model with Naive Bayes classifier which gives the better accuracy of finding the intrusion in Network. The decision tree based model works efficiently with Information gain that helps to find the relationship between the nodes. The malicious node is detected and the result shows that decision tree based models achieves the better results when compared with previous techniques.

ABSTRACT: In present paper Quantitative oxidation of some polyhydroxy compound like mannitol by using simple titric method determination with pyridinium flouro chromate (PFC) reagent.In any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones are change to such substance on simple chemical transformation, as hydrolysis, oxidation,reduction and that form the supporting tissue of plants and are important food for animal and people. other Polyhydroxy compounds act as a key chemical intermediate for the production of a variety of fine or special chemicals such as pharmaceutical drugs, dyestuffs, and also use preparation of oral liquid dosage form by replacement of water by some non- aquoes solvents. Polyhydroxy compounds cointaining two or more than hydroxyl group like mannitol . Mannitol is a type of sugar alcohol which is also used as a medication . It is an osmotic diuretic used to remove excess water and toxins from the body in patients with kidney disease. Due to simplicity and convenience the titrimetric method has widely been ued for the determination of many organic as well as medicinal compounds.

 Abstract

Ground water is the major source of drinking water and over 94% of the drinking water demand is met by groundwater. Water quality monitoring shows that nitrate is present in ground water throughout country at relatively low concentrations, but in areas of intense farming the nitrate-nitrogen concentration may approach or exceed the WHO and IS 10500 ground water permissible limit of 100 mg/L. There are isolated cases where the concentration of Nitrate -nitrogen is very high. This is attributed to disposal of high nitrogen containing waste on land. This study focuses on the actual status of nitrate contamination in various regions of Balotra block of Barmer District, Rajasthan, India. The maximum limit of nitrate is found to be 286mg/l, 285mg/l and 152mg/l in Buriwara, Bhimarlai Station and Jagsa region of Balotra respectively which is higher than desirable and maximum permissible limit for nitrate in drinking water by IS10500 and WHO Standards. On basis of our results we found that most of the groundwater sources are unfit for drinking purposes.

 Abstract

This paper describes our first research experience in Visual Cryptography using AES algorithm by using open-source software tools such as Java(Eclipse), My Sql and etc.Visual Cryptography uses two transparent images. One image contains random pixels and the other image contains the secret information. It is impossible to retrieve the secret information from one of the images. Both transparent images/layers are required to reveal the information. Using secret sharing concepts, the encryption procedure encrypts a secret image into the so-called shares which are noise-like secure images which can be transmitted or distributed over an unsecure communication channel. Using the properties of the human visual system to force the recognition of a secret message from overlapping shares, the secret image is decrypted without additional computations and any knowledge of cryptography.Any visual secret information (pictures, text, etc) is considered as image and encryption is performed using simple algorithm to generate n copies of shares depending on type of access structure schemes. The simplest access structur is the 2 out of 2 scheme where the secret image is encrypted into 2 shares and both needed for a successful decryption.
