As the internet growing day by day secure transmission of information is crucial. Steganography and cryptography both techniques provide data confidentiality, integrity and help us to protect data from day by day attacks. Internet communication has become an essential part of infrastructure now a days and also lots of applications are internet based. So the communication made must be secret to avoid attacks. Steganography is a process of hiding the information of secret messages or one can say that it is an art of sending the hidden data or message over a public network. In the proposed approach message is first encrypted through using The Vigenere Square Encryption Algorithm. After those characters of information or data is embedded into deeper layers through modified LSB method. After that further audio transposition encryption technique is used for audio and accuracy for transposition method is measured in terms of MSE.

This paper takes external sorting as a tool in which processing made simpler. External sorting usually processes the huge data stored on the external storage devices such as a tape, disks or flash or combination etc. When there is huge gas holders details stored in a database, Some process is required in order to process the operations like filtering (sorting), searching over the gas holders details. The kind of sorting (process) required is external sorting which is used to process huge data (databases or big data) available on secondary storage devices. The external sorting is a useful and efficient technique to perform the operations on the gas holders database. To process the information and producing reports or results, an automated tool is required which asks required user details for processing the searching operation, filtering operation is to be performed if any duplication is found in the data set. The results are specified or illustrated in the Results chapter. Data pre-processing is required when there is any inconsistency present in the given dataset which set-right into quality or neat data set.

There exist many pattern matching approaches, which consume more time and unable to perform operations like recording history, finding number of times a pattern is found along with positions, page numbers etc. and they have limitations in performing operations beyond their usual operations. The pattern matching using indexOf method is proposed to find out a specific pattern or multiple patterns at a time in less time complexity. The additional information is reported by recording history operation, information of where the pattern is located like page number, number of times that pattern is found can be processed by searching operation, and multi-process operation searches multiple patterns and returns their locations, page numbers in less time complexity by using indexOf metod as a thread in achieving better efficiency. To do all these operations, an automated tool is required that asks for operation to perform, required details to be provided in that operation, and results going to be illustrated or reported. Data pre-processing is required when there is any inconsistency present in the dataset.

Excess accumulation or inadequate production of certain protein leads to diseases. A drug can play most important role in this scenario. A drug is an organic molecule that triggers or inhibits the function of a biomolecule such as a protein; this will be beneficial to the patient. In the most basic sense, drug design involves the design of small molecules that are complementary in shape and charge to the bio molecular target with which they interact and therefore will bind to it. The process of drug discovery by laboratory experiments is time consuming and very expensive. To reduce the time and cost of drug discovery process, computational techniques are incorporated to speed up the process. Initially dock the molecular fragments obtained by breaking the sigma bonds between the bioactive molecules against tuberculosis to the target site of the protein using docking software known as AutoDock. The score obtained from this is given as input to the program. Then, prioritize the fragments using Multiobjective Differential Evolution (MODE) algorithm with two objectives namely oral bioavailability and free energy. Next step is to design set of ligand molecules that can be represented as an array of fragments. Then analyses the performance of proposed approach by comparing it with another multiobjective optimization algorithm namely Archived Multiobjective Simulated Annealing (AMOSA).

Wireless Sensor Network is a network of wireless devices which is spatially distributed in autonomous tiny computing devices and equipped with sensors, a wireless radio, a processor, and a power source. Wireless sensor networks are deployed in the physical environment to monitor and gather a wide range of information. Due to its dynamic operational and manhandled mobile devices used it also suffers from lot of network security threats. Mostly identity based attacks for example masquerade uses MAC address of some authorized person through malicious device to get hold of the secret information inside the wireless network which largely affects the performance of the network. Identifying a device appropriately is a massive challenge in network securities domain which can be perfectly executed by using the spatial information, a physical property of wireless sensor node. We propose OADL (Optimized Attack Detection & Localization) model which uses the average received signal gain of received signal strength with spatial information correlation to find out the identity of attacker and again using PAM clustering algorithm for detecting the number of with multiple illegitimate identities and eliminate them. When we have the datasets discovered by support vector machines can be used to localize the exact position of multiple illegitimate identities. Evaluating this technique using both wifi (802.11 network) and zigbee model (802.15.4 network) we are able to determine result that attained more than 90% percent hit rate. Using integrated detection and localization algorithms provide high accuracy for multiple attackers.

Edge detection is a very commonly adopted operation in any pattern recognition task like image segmentation as edges are the prominent features which form the outlines in an image. Detecting edges for a color image is a bit difficult than the same in a gray image. In this paper, a novel approach for edge detection in color images is proposed. This approach is based on Multi-directional Sobel filter. For the color arrangement, HSV color space is used. The experimental results demonstrate the efficiency of the proposed approach.

SODAR, an acoustic pulse radar, provides detailed information on dynamic properties of air turbulence in the lower part of the atmosphere. The speed of the transmitted sound wave is responsive to changes in wind swift, due to high rate of susceptibility to temperature variations. The velocity of the transmitted sound wave propagation is much lower when comparing to velocity of electromagnetic waves. Due to this fact the processing of sodar information is significantly simplified and reached better spatial resolution and dead zone. Sophisticated model of tri-static sodar has developed to using general purpose PC to study the properties of sound wave at see breeze.
