We report our new results from wide-field surveys of Herbig-Haro (HH) objects in the nearby star forming regions. The surveys covered approximately 56 deg in Perseus, Taurus, Orion, Monoceros, and other regions. Using refined techniques, we discovered in total 68 HH objects, of which 32 were in Perseus, 4 in Taurus, 13 in Orion, 18 in Monoceros, and 1 in S287 regions. The newly discovered HH ob...

Along with high development of multimedia information technique, the provider of badness information embeds some badness information to image or directly saves as a image file, avoiding the filter of image, which brings extreme effect of security hidden trouble in society. An information audit system based on image content filtering is provided in this paper. At first, we discuss some basic met...

Given a word W in the free group on 2 letters F2, Horowitz showed that the special linear character of W is an integer polynomial in the 3 characters of the basic words of F2. Special linear characters are defined via the trace of their representations, and the polynomial character of an arbitrary W can be found by application of certain “trace relations”, which allow one to write the character...

We present some results on character degree sums in connection with several important characteristics of finite groups such as p-solvability, solvability, supersolvability, and nilpotency. Some of them strengthen known results in the literature.

The aim of this paper is to show that L2(2 f ) are the only nonsolvable groups in which every irreducible character of even degree vanishes on just one conjugacy class. MSC 2000: 20C15

This paper presents seven experiments to determine the optimal size of a box for the input of handwriting characters on PDAs. The experiments involve consideration of boxes for different kinds of characters, different sizes and shapes (square and rectangular), the learning effect, and the age differences of users. The results are assessed in terms of high performance factors (e.g., high charact...

Mate-choice copying is shown when women imitate the mate-choice preferences of other women. We propose that the preferences of women with a pleasant character should be more influential than those of women with an unpleasant character and further suggest that this should apply only when the female demonstrates active interest in the male, rather than disinterest. Here, we presented women as hav...

Two story-telling experiments examine the process of choosing between pronouns and proper names in speaking. Such choices are traditionally attributed to speakers striving to make referring expressions maximally interpretable to addressees. The experiments revealed a novel effect: even when a pronoun would not be ambiguous, the presence of another character in the discourse decreased pronoun us...

A Form-based Intelligent Character Recognition (ICR) System for handwritten forms, besides others, includes functional components for form registration, character image extraction and character image classification. Needless to say, the classifier is a very important component of the ICR system. Automatic recognition and classification of handwritten character images is a complex task. Neural N...

a nontrivial additive character of k. We are given a polynomial f = f(x1, ..., xn) in n ≥ 1 variables over k of degree d ≥ 1 which is a “Deligne polynomial”, i.e., its degree d is prime to p and its highest degree term, say fd, is a homogeneous form of degree d in n variables which is nonzero, and whose vanishing, if n ≥ 2, defines a smooth hypersurface in the projective space Pn−1. For a Delig...
