  • The Number-System of Algebra : Treated Theoretically and Historically
    - ; THE NUMBER-SYSTEM OF ALGEBRA TKEATED THEORETICALLY AND HISTORICALLY BY HENRY B. FINE, PH.D. PROFESSOR OF MATHEMATICS IN PRINCETON UNIVERSITY SECOND EDITION, WITH CORRECTIONS BOSTON, U.S.A. D. C. HEATH & CO., PUBLISHERS 1907 COPYRIGHT, 1890, BY HENRY B. FINE. 66 f 6 T PREFACE. THE theoretical part of this little book is an elementary of exposition the nature of the number concept, of the posi- tive integer, and of the four artificial forms of number which, with the positive integer, constitute the "number- " system of algebra, viz. the negative, the fraction, the irra- tional, and the imaginary. The discussion of the artificial numbers follows, in general, the same lines as my pam- phlet : On the Forms of Number arising in Common Algebra, but it is much more exhaustive and thorough- going. The point of view is the one first suggested by Peacock and Gregory, and accepted by mathematicians gen- erally since the discovery of quaternions and the Ausdeh- nungslehre of Grassmann, that algebra is completely defined formally by the laws of combination to which its funda- mental operations are subject; that, speaking generally, these laws alone define the operations, and the operations the various artificial numbers, as their formal or symbolic results. This doctrine was fully developed for the neg the fraction, and the imaginary by Hankel, in his Complexe Zahlensystemen, in 1867, and made complete by Cantor's beautiful theory of the irrational in 1871, but it has not as yet received adequate treatment in English. this kind is Any large degree of originality in work of from a naturally out of the question.

SVM with the invention of new technologies. Natural handwriting is classifier gives better results as compared to the other one of the easiest ways of information exchange between a human classifiers for the handwritten numeral recognition of Kannada and a computer. Handwriting recognition has attracted many script in [3]. In [6], SVM approach is used to recognize researchers across the world since many years. Recognition of strokes in Telugu script. The set of strokes are segmented into online handwritten Devanagari numerals is a goal of many subsets based on the relative position of the stroke in a research efforts in the pattern recognition field The main goal of character. An SVM based classifier is built for recognition of the work is the recognition of online hand written Devanagari strokes in each subset. A rule based approach is used to numerals using support vector machine. In the data collection recognize a character from the sequence of stroke classes phase, co-ordinate points of the input handwritten numeral are given by the stroke classifier.

Trom the beginning of this century (when Buchanan executed the only archaeological survey that has ever been done in even a part of the South of India) up to the present time, a number of well meaning persons have gone about with much simplicity and faith collecting a mass of rubbish which they term traditions and accept as history.

Discovery number 1: A painting by Salvador Dali. It turns that clocks are not as bad as we think them to be. The units of time that segment the day into hours, minutes and seconds are in fact reconciled by the units of time that compose the Meso American Calendrical system or MAC for short. It was a surprise to me because one of the world’s foremost authorities in calendrical science the late Dr.Jose Arguelles had vilified the numbers of Western timekeeping as a most grievious error . So much so that he attributed much of the worlds problems to the use of the 12 month calendar and the 24 hour, 60 minute, 60 second day, also known by its handy acronym 12-60 time. I never bought into his argument that the use of those time factors was at fault for our largely miserable human-planetary condition. But I was content to dismiss mechanized time as nothing more than a convenient tool to facilitate the activities of complex societies.

  • Preliminary Proposal to Encode Devanagari Letter Numerals L2/17
    Preliminary proposal to encode Devanagari letter numerals Srinidhi A and Sridatta A Tumakuru, India [email protected], [email protected] January 17, 2017 1 Introduction This is preliminary proposal to encode letter numerals found in Devanagari script. The objective is to bring them to the attention of the Unicode Technical Committee and to seek advice regarding the encoding of the numerals. 2 Background The modern Devanagari has a set of digits with the use of zero. In addition to digits, a distinct numerical notation system is attested early and medieval manuscripts. These numerals are referred as ‘letter numerals’ in the scholarly literature to distinguish from regular digits. The letter numerals were largely used for marking page numbers in manuscripts. These numbers are derived from Brahmi numbers (U+11052…U+11065). These Devanagari numerals are paleographically analogous to letter numerals found in closely related North Indic scripts like Bhaikṣukī, Tocharian, Khotanese, Ranjana, Newa and Sharada. Often the numbers were used alongside with digits. Letter numerals are written in the margin to the left, whereas digits are written in the margin to the right. North Indian letters numerals are distinct from alphasyllabic numeration used in of other parts of India such as Aksharapalli and Katapayadi systems. In these notations existing letters are reused, whereas the North Indian numerals are evolved from Brahmi numbers. The term ‘letter-numerals’ here does not symbolize that these numerals are evolved or conceptually derived from letters. These numerals were used predominantly in states of Gujarat and Rajasthan of Western India. These numerals occur in both ‘Jainanagari’ and regular styles of Devanagari.

A lot research is getting done in this field in which the point of interest is to receive as higher accuracy as possible in a distorted writing. That is as we know the way of writing of different person is different, so to recognize every writing with a greater accuracy is the point of concern. In this paper we proposed a method for different languages handwritten character recognition. The main focus is to train the model with pre-set data and then using that trained model to test the handwritten character passed to it. In our proposed method we used MATLAB to design our code, in this the model can be trained on runtime also.

  • Comparison of Feature Extraction Techniques for Gujarati Isolated Numerals Dr
    International Journal of Modern Trends in Engineering and Research www.ijmter.com e-ISSN No.:2349-9745, Date: 28-30 April, 2016 Comparison of Feature Extraction Techniques for Gujarati Isolated Numerals Dr. Mamta Baheti Department of Computer Science, Hislop College, Nagpur [email protected] Abstract— This paper is for recognition of isolated Gujarati numerals. As per the reported work, Gujarati is widely spoken across world along with Indian states. In the proposed study, we have used noisy handwritten numerals in procedure of training and testing. After applying pre-processing to the scanned image, they are then treated with the proposed algorithm. In our proposed algorithm we have used affine invariant moments and invariant moments as feature extraction technique and Gaussian distribution function as classifier. We produced pleasing results for some numerals. We compared the results for both the extraction techniques and found that for our database Affine invariant moments gave better results but they could be improved by giving better quality images for training and testing. Keywords- Affine Invariant Moments; Invariant Moments; Gaussian Distribution Function I. INTRODUCTION In the present scenario, every day task is being computerized. Each user wants the computer to have user-friendly interactions. In recent years a good amount of reported work has been contributed for recognition of handwritten characters. Variation in writing styles and recognition accuracy has a milestone to achieve. It has been noted that there are approximately 22 regional official languages are used in India [1-4]. Every regional official language has the wide variety as well some peculiar similarities. Out of these, one language is Gujarati which is spoken in Gujarat and some parts of India and also in South Africa.
