The compression is a vital field in image processing which reduces the bandwidth during data transfer in multimedia communications. In this paper, we propose Image Compression using Self Organizing Map (SOM) and Discrete Wavelet Transform (DWT) with Error Correction. The input image is considered from standard database and modified to 4x4 blocks and rearranged as 16x4096 input vectors and appli...

Descriptive statistics include measures of central tendency and variability. Measures of central tendency include mean, median, and mode. The mean is the arithmetic average of data from interval or ratio scales. The median reflects the 50th percentile score. The mode is the most frequently occurring value of a data distribution. Measures of variability include range, interquartile range, standa...

We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...

The location of the Reference Value for an analyte within the population distribution affects the magnitude of error due to methodological bias. Using the gaussian distribution, we evaluated the effects of systematic and proportional biases of the method (positive and negative), mean value, and standard deviation on the magnitude of error. We chose four Reference Values for cholesterol as a mod...

the present research was planned to evaluate the skill of linear stochastic models known as arima and multiplicative seasonal autoregressive integrated moving average (sarima) model in the quantitative forecasting of the standard runoff index (sri) in karkheh basin. to this end, sri was computed in monthly and seasonal time scales in 10 hydrometric stations in 1974-75 to 2012-13 period of time ...

The dual adaptive importance sampling (DAIS) technique allows for the evaluation of the word and bit error rates of linear block forward error correction codes down to extremely low values. This paper presents results from performance evaluation of certain LDPC codes using the DAIS technique. The standard Monte Carlo simulation results and the union bound are provided, where available, for comp...
