Pattern recognition needs as basis knowledge about the object. The knowledge of object can be obtained by feature extraction with image processing tools. The success of any such practical system depends critically upon how far a set of appropriate numerical attributes or features can be extracted from the object of interest for the purpose of matching or recognition. In this paper, two different combinations of image features are proposed and their comparative results for trademarks recognition are discussed. The proposed features involve some simple ratios of the image pixels as well as some geometric moments. These features are invariant to translation, rotation and scaling. The goal was achieved by segmenting the image using a connected-component (nearest neighbours) algorithm. Then the features are used as inputs for a backpropagation neural network for the learning and matching tasks. The effectiveness of the proposed feature sets is tested with various trademarks, and the results are encouraging.","PeriodicalId":286459,"journal":{"name":"Proceedings.

To predict the intrinsic equivalent circuit parameters of the device from DC data, the measured DC characteristics are first simulated by employing a non-linear DC model. The effects of biasing on the device AC parameters are evaluated for low-noise applications. An improvement greater than 10% in predicting the AC response of the device is observed. The concept of depletion layer modification caused by the transverse electric field inside the channel is introduced for accurate Miller's capacitor modeling. It is assumed that with increased device biasing there are more unbalanced positive ionic charges in the gate depletion towards the drain-side of the Schottky barrier. The electric field lines originated by these uncompensated charges induce an opposite charge density in the gate electrode. This modifies the gate biasing and hence the Schottky barrier depletion. As a result, the values of intrinsic AC device parameters change. It is observed that accurate DC modeling is key to prediction of an accurate AC small signal equivalent circuit of a device.","PeriodicalId":286459,"journal":{"name":"Proceedings.

Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language. The author has designed an editor titled \"A Multilingual Unicode Editor\" which can be used for numerous applications such as sending/receiving emails, web page development and chatting etc. The Unicode Organization was founded in 1991 to design and promote a universal, uniform, unique, unambiguous worldwide character-encoding standard. The Unicode Organization released its first version of standard, Unicode Standard 1.0 in the same year. The current version of the Unicode Standard contains 49,194 distinct coded characters. These characters cover principal written languages, and symbol systems of the world. Formally the printed books and online documents that extend the specification and informative content define the Unicode standard.","PeriodicalId":286459,"journal":{"name":"Proceedings.
