Quaternion Gravi-Electromagnetism
Defining the generalized charge, potential, current and generalized fields as
complex quantities where real and imaginary parts represent gravitation and
electromagnetism respectively, corresponding field equation, equation of motion
and other quantum equations are derived in manifestly covariant manner. It has
been shown that the field equations are invariant under Lorentz as well as
duality transformations. It has been shown that the quaternionic formulation
presented here remains invariant under quaternion transformations.Comment: Key Words: Quaternion, dyons, gravito-dyons, gravi-electromagnetism.

Handwritten Script Recognition using DCT, Gabor Filter and Wavelet Features at Line Level
In a country like India where more number of scripts are in use, automatic identification of printed and handwritten script facilitates many important applications including sorting of document images and searching online archives of document images. In this paper, a multiple feature based approach is presented to identify the script type of the collection of handwritten documents. Eight popular Indian scripts are considered here. Features are extracted using Gabor filters, Discrete Cosine Transform, and Wavelets of Daubechies family. Experiments are performed to test the recognition accuracy of the proposed system at line level for bilingual scripts and later extended to trilingual scripts. We have obtained 100% recognition accuracy for bi-scripts at line level. The classification is done using k-nearest neighbour classifier
Prototype Implementation of Real Time CAN Driver for Distributed Embedded Applications
The purpose of this proposed prototype is to make it useful in various distributed embedded applications. This system is implemented by using FreeRTOS, LPC1769, CAN (Controller Area Network), LwIP (Light Weight Internet Protocol) Protocol and Sensors. Now a day’s real time communication is one of the key features in distributed embedded systems. Using FreeRTOS, distributed embedded application performance will be improved as compared to general operating system. FreeRTOS comprises CAN & LwIP protocol stack which transfer real time data from one microcontroller node to another. The Sensor acts as input to this prototype and microcontroller node in compliance of FreeRTOS that comprises the Real Time CAN driver which is used for secured data transfer. Real Time LwIP protocol stack is implemented on top of FreeRTOS to feed the data to PC Host application. It consumes less RAM as compared to other communication protocols such as TCP, UDP, etc. for data transmission so that the memory bandwidth is reduced. In this system, based on LwIP stack the data will be transferred from microcontroller Node to the Host application. PC Host application is used for data monitoring and control. Data acquisition and control of distributed embedded applications will be improved with help of this designed prototype.

Unified Angular Momentum of Dyons
Unified quaternionic angular momentum for the fields of dyons and
gravito-dyons has been developed and the commutation relations for dynamical
variables are obtained in compact and consistent manner. Demonstrating the
quaternion forms of unified fields of dyons (electromagnetic fields) and
gravito-dyons (gravito-Heavisidian fields of linear gravity), corresponding
quantum equations are reformulated in compact, simpler and manifestly covariant
way
SOME RESULTS ON SEMI-REFLEXIVITY AND REFLEXIVITY IN LOCALLY CONVEX SPACES
In this paper we discuss that if E[] is a barreled space such that every bounded subset of E is relatively compact, then E[] is reflexive, and that a barreled space E[Ï„] in which there is a denumerable system of convex compact subsets is reflexive. We also discuss Some hereditary-type properties of reflexive locally convex spaces. Keywords: Bornological space, barreled, hereditarily-reflexive, M-space, quasi-complete, reflexive, strong dual.

Research Notes : Pakistan : Path-coefficient analysis of developmental and yield components in soybean
Abstract: Interrelationships among different characters were determined by simple correlations and path-coefficient analysis using 36 diverse and elite cultivars representing different geographical origin. The results revealed a highly significant positive association of the branches per plant and pods per plant with grain yield. The pods per plant also showed a high direct influence on grain yield. Thus, from this investigation, it is suggested that pods per plant and number of branches per plant are the primary yield components that should be given due emphasis in selecting high yielding genotypes in soybean
Clustering Based Classification and Analysis of Data
This paper presents Clustering Based Document classification and analysis of data. The proposed Clustering Based classification and analysis of data approach is based on Unsupervised and Supervised Document Classification. In this paper Unsupervised Document and Supervised Document Classification are used. In this approach Document collection, Text Preprocessing, Feature Selection, Indexing, Clustering Process and Results Analysis steps are used. Twenty News group data sets [20] are used in the Experiments. For experimental results analysis evaluated using the Analytical SAS 9.0 Software is used. The Experimental Results show the proposed approach out performs
Analysis of Social Networking Sites Using K- Mean Clustering Algorithm
Clustering is one of the very important technique used for classification of large dataset and widely applied to many applications including analysis of social networking sites, aircraft accidental, company performance etc. In recent days, Communication, advertising through social networking sites are most popular and interactive strategy among the users. This research attempts to find the large scale measurement study and analysis, effectiveness of communication strategy, analyzing the information about the usage, people’s interest in social network sites in promoting and advertising their brand in social networking sites. The significance of the proposed work is determined with the help of various surveys, and from people who use these sites. Further a more specific pre-processing method is applied to clean data and perform the clustering method to generate patterns that will be work as heuristics for designing more effective social networking sites
Studies on Variability in Wheat ( Triticum aestivum Linn.)
Significant treatment mean sum of squares for eleven characters studied revealed the presence of considerable amount of variability in F2’s of 21 crosses, 7 parents and 2 checks. The magnitude of GCV and PCV were high for productive tiller per plant and spikelets per spike; whereas, days to maturity and days to 50 per cent flowering exhibited least GCV and PCV. The high heritability was accompanied with high genetic advance as per cent of mean for length of spike, productive tillers per running meter, 1000 grain weight and grain yield per plant indicating additive genetic control in the expression of these characters
Shape Invariant Potential and Semi-Unitary Transformations (SUT) for Supersymmetric Harmonic Oscillator in T4-Space
Constructing the Semi - Unitary Transformation (SUT) to obtain the
supersymmetric partner Hamiltonians for a one dimensional harmonic oscillator,
it has been shown that under this transformation the supersymmetric partner
loses its ground state in T^{4}- space while its eigen functions constitute a
complete orthonormal basis in a subspace of full Hilbert space.
Keywords: Supersymmetry, Superluminal Transformations, Semi Unitary
Transformations.
