Predictive coding has proven to be effective for lossless image compression. The predictive coding estimates true color of a pixel based on the true colors of its neighboring pixels. To enhance the accuracy of the estimation, we propose a new and simple predictive coding algorithm that uses the quantized colors of neighboring pixels to estimate the true color of a pixel. The estimation is based on the majority of quantized colors of the three neighboring pixels. Experiments, over a set of true color 24-bit images whose colors of pixels are quantized ...

This study was to create a pattern of website development that affects the trust in the decision for medical tourists in Thailand because nowadays the competition of medical tourism is increasingly higher in several countries, such as Singapore, Malaysia and India, where tourism is mainly promoted by website that is used as a source of information for the decision of visiting to medical tourism. Particularly, the interface factors on a website are important and affect the decision. Although currently there are many studies on developing a website ...

Portfolio management strategy enables investors to reduce risk and maximize return. Investment in different stocks in equity market helps reducing non-systematic risk however systematic risk of portfolio obviously affected by macroeconomic conditions. Different stages of business cycle associates with changes in macroeconomic environment together with business sentiment and different market expectations which impact performance of specific asset classes in each stage. Equity in different stock sectors responses differently in various economic and ...

This dissertation proposes a permutation test and a permutation procedure for testing on partial regression coefficients from a multiple linear regression with first-order autocorrelation where the distribution of the error terms is not necessarily normal. The proposed permutation procedure can be directly conducted in the test without having to fit back to the model, which is not the same procedure as in previous permutation tests, and a proposed permutation test is considered based on a random permutation test. In addition, the asymptotic ...
