Abstract

Hashiwokakero is a logic puzzle game that sharpen the brain and very popular in Japan. This paper discusses about how to find a solution in the Hashi puzzle game using Hashi Solving techniques, such as: Just Enough Neighbor, One Unsolved neighbor, Few Neighbor, Leftovers and Isolation. Hashi Solving techniques are used to find and build bridges that can definitely be built across the island, while Depth First Search (DFS) will search and build bridges that have not been found by Hashi Solving techniques. The results shown that Hashi Solving Techniques and DFS able to solve every Hashi puzzle scenario.

Abstract

We present a technique of image encryption based on Hill cipher system that provides better security than existing approach of Bibhudendra Acharya et al. by rendering the image content completely scrambled using multiple self-invertible keys, block shuffling and a new developed pel transformation. The Hill cipher algorithm is one of the symmetric key algorithms having several advantages in encryption. However, the inverse of the matrix used for encrypting the plain text in this algorithm may not always exist. Moreover this algorithm is susceptible to known plain text attack. Our proposed algorithm is aimed at better encryption of all types of images even ones with uniform background and makes the image encryption scheme more secure.

Abstract

In this paper, trade-off between effect of registration error and number of images used in the process of super resolution image reconstruction is studied. Super Resolution image reconstruction is three phase process, of which registration is of at most importance. Super resolution image reconstruction uses set of low resolution images to reconstruct high resolution image during registration. The study demonstrates the effects of registration error and benefit of more number of low resolution images on the quality of reconstructed image. Study reveals that the registration error degrades the reconstructed image and without better registration methodology, a better super resolution method is still not of any use. It is noticed that without further improvement in the registration technique, not much improvement can be achieved by increasing number of input low resolution images.

Abstract

Transformers of small ratings have a wide field of application. They are generally designed and fabricated using standard stampings available in the market. The design is made according to guidelines given in text-books. But such guidelines do not yield a cost-optimal solution. It may even fail to give a feasible solution if design variables are not properly chosen. This paper presents a method to get the cost-optimal solution subject to usual design constraints. The line of approach is completely different from that given in the standard text-books. Computer programs have been developed for finding out the cost-optimal design using standard stampings and case studies have been made on its basis.

Abstract

Error Correcting codes are normally used for protecting transmitted information bits in a noisy channel. The information bits are encoded into error correcting codes which will be transmitted into the channel and on the receiver side, the received codes will be decoded back into the transmitted information bits. In this paper, a technique of generating binary error correcting codes that meet the Gilbert-bound and a simple encoding-decoding mechanism will be presented. To show the performance of the error correcting codes, a Binary Symmetric Channel is considered for transmission.

Abstract

The security of Object oriented software is well managed by software metrics because they promise accurate, reliable, faster and more efficient ways with proven techniques and standard notations. The Software Security Life Cycle (SSLC) was developed providing a basis to help software Security planning. In this paper, software metrics, which have been proposed for Software Security, are used and applied to programming language. In software industries, the cost of Security of large-scale software has put emphasis on the need to manage the in earlier phases and is statistically estimate the security of large software system and to identify error prone modules.

Abstract

Permanent Magnet Synchronous Motor (PMSM’s) are used in many applications that require rapid torque response and high – performance operation. New developed materials such as magnetic materials, conducting materials and insulating materials as well as several new applications have greatly contributed to development of small and special purpose machines. Using such materials the size of the motor would considerably reduce and high performance motors can be built. Due to several new applications these motors are quite popular and use in a developing country such as India for Automotive application.In a permanent magnet synchronous motor, the dc field winding of the rotor is replaced by a permanent magnet. The advantages are elimination of field copper loss, higher power density, lower rotor inertia and more robust construction of the rotor. The demerits are loss of flexibility of field flux control and possible demagnetization effect. The PMSM has higher efficiency than an induction motor, but generally its cost is higher, which makes the life cycle cost of the drive somewhat lower. PMSM particularly at low power range are widely used in industry. Recently, the interest in their application is growing, particularly up to 100 KW, only reluctance motor are simpler in construction and in assembly procedure then PMSM, but reluctance motor generally developed less torque per unit of current and per unit of weight. Therefore, on a basis of power output per unit weight (and general, per unit volume) the PMSM is superior to all other brushless synchronous motor especially with the commercial feasibility of rare earth magnets. Section 1. describes the introduction section 2.describes Classification  of permanent magnet AC motor section 3. describes the conclusion.
