ABSTRACT: This paper presents novel quadruple cross-coupled memory cell designs, namely Proposed cell (BQCCM10T cell), with complete protection against single event upsets and double-node upsets. The proposed cell BQCCM10T consists of four cross-coupled input-split inverters and a buffer.Memory cell circuits are more sensitive to external radiation phenomena that are likely to cause the occurrence of soft errors SEU & DNU. Therefore, the tolerance of the circuit to the soft errors is a stern requirement in memory cell circuit designs. Since the traditional error-tolerant methods result in significant cost fines in terms of power, area, and performance, the development of low-cost hardened designs for storage cells(such as latches and memories)is of increasing importance. The Proposed cell achieves complete SEU and DNU tolerance through feedback and buffering mechanisms among its internal nodes.The proposed BQCCM10T cell has high robustness and high Read Access time and Write Access Time. With the help of T-Spice, simulation results of several SRAM cells and the BQCCM10T cell are compared.Hence the proposed cell BQCCM10T is used for highly terrestrial reliable low voltage applications..

ABSTRACT: Today the synthetic speech of highest quality, generated by existing speech synthesis systems are not close to actual human speech. As the number of applications for synthetic speech increases, the naturalness and the intangibility of synthetic speech will become an important factor in determining its use. This paper presents a comparative study on investigating the naturalness and the intelligibility of the newly proposed Auto Regressive Moving Average (ARMA) based speech synthesis method for female voice. The synthesized speech was analyzed based on subjective and objective measure. The subjective measures, signal-to-noise ratio (SNR), peak signal-to-noise ratio (PSNR) and.......

ABSTRACT: In this paper, a new approach to assess the skew angle for scanned/printed documents and historical document images has been proposed. This is substantial for an automatic document processing system (as text and image segmentation) to avert errors in auxiliary stages. The proposed tactic is based on the statistical analysis of the slope of the connected lines in the document. The proposed technique detects skew and corrects it by initial letter (X1, Y1+200) from left margin of the resized (800X800) image and (X1+200, Y1) from top, (X1, Y1+200) from bottom margin. Final letter (X2, Y2-200) and (X2-200, Y2) were chosen from right and bottom margins of the same image. The skew angle estimation is done for standard skewed dataset and effective correction of the same is performed with minimum errors..
