Analysis of Program Outcomes Attainment for Engineering Graduates for NBA Accreditation

Therese Yamuna Mahesh — 2015-09-20

One of the requirements of the National Board of Accreditation (NBA) for accrediting a program in an academic institution in India is the analysis of the attainment of program outcomes by the students. This paper gives a method for analysing the extent to which the students attain the program outcomes on completing the program. The method illustrated analyses the attainment level for a single student as well as a batch. The initial calculations are done using excel and the same database is used to train a neural network to get the required output. Data set of individual students or batch of students can be given to the trained network to get the attainment level of program outcomes. The analysis can be done by using the marks secured by the students or by defining rubrics for the respective courses.

An Assessment of Video Quality using Watermark

Jyothi Lakshmi S — 2015-05-26

Video applications are much prevalent because of their recurrence in use on web these days. The watermarking can be utilized to appraise the video quality by assessing the watermark debasement. The image watermarking strategy for the video quality estimation is established on a 3-level discrete wavelet change (DWT). Here, also propose a quad tree decomposition of video for watermarking embedding algorithm to keep the balance between watermarks intangibility and its capacity to adapt up to errors. The watermark is inserted into the tree structure of an image with fitting implanting quality chose by measurably examining the attributes of the image. The correlated DWT coefficients over the DWT sub bands are classified into Set Partitioning in Hierarchical Trees (SPIHT). Those SPHIT trees are again decomposed into an arrangement of bitplanes. The insertion and extraction of the watermark in the cover video is discovered to be less difficult than other technologies. The True Detection Rates (TDsssR) determine the video quality by comparing extricated watermark and original watermark. The exactness of the quality estimation is made to approach that of Full-Reference measurements by referring True Detection Rate. In this manner proposed plan has great computational effectiveness for practical applications.

Implementation of an Competent Fixed Field Calculative Unit in Cryptography

Mr. Manoj Kumar Dixit — 2015-01-25

Cryptography is not the only means of providing information and network security, but rather one set of techniques. The most critical component of an elliptic curve processor is its arithmetic unit. Typical arithmetic unit includes an adder or subtractor, multiplier, squarer and an inverter. In this paper, we propose, an efficient finite field arithmetic unit using elliptic curve cryptographic method, which is used in most of the cryptographic applications to compute arithmetic operations. Addition operation is done with one n-bit XOR operation, for squaring operation LSB firstsquaring method is used and extended euclidean algorithm for inversion operation. We also present the comparison of two methods Karatsuba and Montgomery, which are used for multiplication operation and among them Karatsuba method is used because of its efficiency. These operations implemented on FPGA Spartan3 tool and simulated using VHDL on Xilinx Isim simulator.

Comparative Study of Test Data Generation Techniques

Anuranjan Misra — 2015-07-25

Test Data Generation, an important part of software testing, is the process of creating a set of data for testing the adequacy of new or revised software applications. It may be the actual data that has been taken from previous operations or artificial data created for this purpose. Test Data Generation is seen to be a complex problem and though a lot of solutions have come forth most of them is limited to toy programs. Search Based Software Engineering has been applied in many applications. Evolutionary testing designates the use of metaheuristic search methods for test case generation.

Survey of Image Registration Techniques

Mandar C. Lokhande — 2015-03-16

Image registration is widely used in many fields such as computer vision, medical imaging, military and remote sensing. For a pair of images (a reference image and a sensed image), the main objective of image registration is to find an optimized transformation from the sensed image to the reference image so that the transformed image is as similar as possible to the reference image up to date, a number of image registration methods have been proposed. The existing registration methods can be roughly classified into two categories: area based and feature based. Area-based methods focus more on the images’ gray spaces than on the images’ feature spaces.
