Black hole attack analysis in vehicular ADHOC Network

The use of wireless links furnishes a VANET unsafe to malicious attacks for example Denial of Service, black hole attack, Sybil attack, selective forwarding and altering routing information. In Vehicular Networks are contemplated as the unique class of wireless networks, also called as VANET. It is a major part of Intelligent Transport System (ITS). VANET technology is recognized for enhancing road safety and transport efficiency. But, there are huge security issues in VANET, therefore, there must be a reliable way for communication which is quite tedious and important concern. In this review article, we studied Black Hole attacks under CBR/UDP traffic pattern using various protocols from various research papers of high quality. There are possibilities of various attacks like an active and passive attack on the network to access data. As we know there are many issues in VANET and especially security issues. Our research work will be carried out using NS-2 simulator. Besides this, a detailed study of the attack examined because there are abundant numbers of attack available. These attacks are divided into an active and passive attack and further, these two are classified. In this review paper, we convoluted the diverse class of attacks and their depth in an ad-hoc network.

Higher dimensional cosmological models with variable gravitational and cosmological constants

A higher-dimensional cosmological model with the gravitational and cosmological constants generalized as coupling scalars in Einstein theory is considered in the framework kaluza-klein theory of gravitation. A general method of solving the field Equations is given. Exact solutions for matter distribution in cosmological model satisfying G=G_o (R/R_o )^mis presented. The corresponding physical interpretations of the cosmological solutions are also discussed.

Medical Image Denoising and Enhancement using DTCWT and Wiener filter

Image denoising is the process to remove the noise from the image which contains noise. Wavelet transform technique is a unique mathematical manipulation framework used for medical image denoising and enhancement implementation. The wavelet techniques are effective to remove the noise due to their ability to capture the energy of a signal in a few energy transform values. A dual-tree complex wavelet transform is used to present the image enhancement process. The proposed technique has the cascaded structure of DTCWT used for generation of different frequency bands for analysis. In this paper, a denoising approach based on dual-tree complex wavelet and Wiener filter technique is used. The result has a better balance between smoothness and accuracy than the DWT and is less redundant than SWT. We used the SIM (Structural Similarity Index Measure) along with PSNR (Peak Signal to Noise Ratio) to assess the quality of denoised images.

Image Enhancement using DCTWT and Interpolation Techniques

As image enhancement is the main issue for biomedical images, this paper aims to present the methods using wavelets to enhance it. Digital image processing plays a vital role in today's new digital imaging devices. To perform the operation on the low-quality input images, frequency domain manipulations are widely used. Image enhancement is one of the types of processing in digital image processing domain. To perform this operation sophisticated wavelet transformation is used which has better enhancement as compared to their spatial domain counterpart. In the proposed paper, a novel technique for the biomedical image, general images up to certain MB enhancement using dual-tree complex wavelet transform is used. Dual-tree complex wavelet is a parallel combination of two discrete wavelet transform which has the property of shift invariance which results in lesser artifacts generated in output enhanced image. Interpolation is using for high precision in this paper B-spline interpolation give better results. To perform this operation and finding out the best possible transform among the available wavelet family. Proposed implementation has three transforms namely symlet, D'mayer, daubechies, and haar transform are used. The input image is first decomposed using wavelet transform to generate frequency bands, values of PSNR, Q-index and SSIM are calculated for study enhancement results.

Non-Market issues in WTO: With special reference to China

The Multilateral Trading System was created in the 1940`s with the GATT, containing clear objectives to liberalize and promote trade as an instrument of economic development. Aiming to become universal, the Multilateral Trading System gave support and incentives to both market and Non-Market Economies (NMEs) to participate in its activities. With the strengthening of the Cold War, however, NMEs left the negotiations leading to General Agreement on Trade and Tariffs (GATT).

A study on RCA as parialy replacement with natural aggregate

Recycle Concrete Aggregate has also been described as “the most revolutionary development in concrete construction for several decades”. It has proved to be beneficial from the point of economic, environmental benefits and Preservation of non-renewable recourses this thesis presents a study conducted on mechanical and durability properties of recycled aggregates concrete. The investigation covered concrete mixes at the water-cementitious material with a ratio of 0.4. Ordinary Portland cement of 43-grade was used in this study. The percentage of recycled aggregates that partially replaced natural aggregates by weight were 0%, 15%,30%, 45%, 60% and 75%. Concrete cubes and cylinders were cast and tested in laboratories. The optimum proportion of replacement was found by conducting tests on mechanical properties like Compressive strength test and Split tensile strength test. To assess the corrosion and durability characteristics of recycled concrete aggregates Acid and alkalinity resistance test were performed. The results show that the optimum replacement of recycled aggregates with natural aggregates was 45%. Up to 45% replacement, it is possible to gain the same strength as conventional concrete. Beyond 45% replacement the strength results following a decreasing trend.
