Abstract: A cyber attack is any type of offensive man-oeuvre employed by nation-states, individuals, groups, or organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system. These can be labelled as either a cyber campaign, cyber-warfare or cyber-terrorism in different context. Cyber attacks can range from installing spyware on a PC to attempts to destroy the infrastructure of entire nations. User behaviour analytics and SIEM are used to prevent these attacks. Social platform attacks target websites with large user bases, such as Face book, LinkedIn, Twitter and Instagram..............

Title : A Review on Different Datamining Schemas with their Design Methodologies

Abstract: Database design for data warehouses is based on the notion of the snowflake schema and its important special case, the star schema. The snowflake schema represents a dimensional model which is composed of a central fact table and a set of constituent dimension tables which can be further broken up into sub dimension tables. We formalise the concept of a snowflake schema in terms of an acyclic database schema whose join tree satisfies certain structural properties. We then define a normal form for snowflake schemas which captures its intuitive meaning with respect to a set of functional and inclusion dependencies. We show that snowflake schemas in this normal form are independent as well as separable when the relation schemas are pairing wise incomparable. This implies that relations in the data warehouse can be updated independently of each other as long as referential integrity is maintained. In addition, we show that a data warehouse in snowflake normal form can be queried by joining the relation............

Title : Nano electromechanical systems: Its features, Challenges and Carbon Nanotubes

Abstract: With the study of nanoscale effects, Nano electromechanical systems (NEMS) present interesting and unique characteristics, which diverges greatly from their predecessor micro-electromechanical systems (MEMS). When MEMS are scaled to submicron dimension[5], NEMS are formed. NEMS are able to preserve very high mechanical responsivity (small force constants); the quality (Q) factors of resonance are remarkly higher than those of electrical resonant cavity (i.e. in range Q = 103 – 105) and acquire tremendously high fundamental frequencies concurrently. These features are responsible for technological applications like signal processing components, actuators and ultrafast sensors...........

Abstract: Integrating physics, computer science and mathematics quantum computing has evolved in the last two decades from an imaginative idea to one of the most interesting field of quantum mechanics. Altering the model underlying information and computation from a classical mechanical to a quantum mechanical gives faster algorithms. Quantum algorithm can execute a selective set of tasks widely more effectively than any classical algorithm, but for many tasks, it has proven that quantum algorithms give no actual benefit. The scope of quantum computing applications is still being examined. This research paper gives an overview of quantum computer, explanation of qubit and discusses about the various applications of quantum mechanics to verify the existence of quantum computers............

Title : Parallel Random Motion-Selective Rank Band Based Image Compression Using Hybrid Multi Wavelet Transform
Country : India
Authors : B. Sridhar || S.Jagadeesh
: 10.9790/0661-1905052334     logo

Abstract: A Hybrid Multi Wavelet Transform (HMWT) based 2D magnetic resonance (MR) image compression method is proposed. The proposed work presents a novel MR image compression method using Parallel Random Band Selection Method and Motion-Selective Rank Algorithm (PRMRB). In the proposed method, 2D multispectral MR image is spectral decorrelated and temporal decorrelated in the first and second stage of intra and inter band correlation. From this process, the main spectral band component for analysis is selected. These components were given to Parallel Random Band Selection Method, where the registration of sequence of band components is done. In this approach, the spectral bands are treated independently, so there will be many sequences as the number of spectral bands............

Abstract:The core objective of our paper is to compare K means clustering and watershed algorithm using MATLAB tool. The comparison is based on their performance, accuracy, and its geometrical dimension. A Brain tumour is one of the major cause of death in current space. Many researchers and scientist are constantly working from last two decades and proposing, unlike algorithm which can be integrated with biotechnology field for effective results. MRI image plays a predominant role in identifying and extracting the tumour part. It offers better results of various soft tissues as compared to CT scan, X-ray, and Ultrasound. Segmentation of image is a grueling task because of intensities.............

Abstract:In spite of the huge advantages got from the selection of cloud computing idea, its famous adoption has been determined usually by security concerns. The broadened assault surface in a cloud environment makes it more defenseless against existing and developing security dangers. Customary information security approaches have been discovered inadequate in abridging these dangers and this obnoxious pattern has required the requirement for an advanced methodsto deal with datasecrecy. This paper proposes an improved
component to guaranteeing information security by utilizing RC6algorithm. we went for utilizing the quality of these techniques to gains a powerful instrument for guaranteeing secrecy and integrity of information in the cloud .The results obtained from proposed system shows that ability to resistance the threats and attacks and able to keep user's data secure and trusted.
