Based on the assumption that the distribution of DCT coefficients in H.264 encoder follows Cauchy distribution, a macroblock layer bit rate model was derived. Then, the distortion was predicted by a linear model using the actual distortion and the quantization parameters of the previous frame.

In this research, the SOLO (Structure of the Observed Learning Outcome) Taxonomy presented by Australian scholars Biggs and Collis (1982) was adopted, and students studying the fifth and sixth grades in Taipei area were chosen as research targets.This study was primarily implemented with a quantitative analysis and supported by a qualitative analysis. In order to carry out the research, a questionnaire had been designed with criteria suggested by Jones et al.(2000), including "describing data","organizing and reducing data","representing data" and "analyzing and interpreting data." This questionnaire consisted of open-ended questions, and after analyzed with qualitative methods, the responses were classified and scored based on standards set in SOLO Taxonomy. Then the quantitative method "Partial Credit Analysis" from Rasch model was adopted in examining the reliability, validity and consistency of outcomes from the qualitative analysis.

The computational complexity has been reduced about 5 times over against the original one. Moreover, the interpolation and quantization processing of CW is more reasonable; 2. A secondary power normalization algorithm is proposed in this dissertation. This normalization algorithm ensures that the energy sum of SEW and REW is 1. So, the energy ratio of SEW and REW can be achieved only by using SEW energy. This ratio is applied in REW quantization and CW composition; 3. For more efficient quantization for Slowly Evolving Waveform magnitude, Rapidly Evolving Waveform magnitude and power parameters, firstly, by applying the Equivalent Rectangular Bandwidth theory, classifiable multi-codebooks method, analysis-by-synthesis approach and so on, a predictive AbS multi-codebooks SEW magnitude quantization scheme is proposed. In the scheme, pitch information is exploited to determine which codebook is searched; secondly, for REW magnitude quantization, this dissertation proposed a DCT-matrix multi-codebooks quantization scheme. The classification in muti-codebooks is based on pitch and quantized SEW power. The multi-codebooks structure may offer more the information in quantization and solve the problem of the bit requirement limits in quantization by consuming some extra storage space; Furthermore, for the switch quantization of CW gain, a new classified parameter is proposed.

As to the first research topic, we present a 'Noble Brand Positioning Four Master Phases Theory': Brand Space Theory, Brand Capital Theory, Brand Value Theory and Brand Circle Theory in advance. Following based on the Principal Component Analysis of statistical theory, we implemented the quantitative research in the 'Noble Brand Positioning Four Master Phases Theory'. We used the most famous fast food brand 'McDonald' s' as the sample space. The simulation test result shows that the Overall Index Explanatory Power is 83% under the Cronbath' s a is 0.88 through the quantitative verification. This result gives a strong support in defining the Noble Four Niche Phases Theory as the important strategic factor in establishing brand positioning index. After completing the quantitative research, the Principal Weight of each Sub-Niche is positive. This also implies that the Noble Brand Positioning Four master Phases Theory represents positive affection to brand positioning index. We also created the following Sub-Niches those are rarely mentioned in the past literatures. The Sub-Niches are:'Endless Running Strategy, Business Environment Strategy, Physical Capital Strategy, Brand Logo, Brand Music, Business Life Strategy, Personnel Capital Strategy, Life Cycle Strategy, Trust Mask Strategy, Re-Positioning Strategy, Word-Power Strategy, Globalization Strategy, Network Revolution Strategy and Green Brand Strategy'. The quantitative verification model can classify the responses of the sampling space into groups. After that, we used the quantitative verification process to classify the Target Consumer. And through the Principal Component Analysis, the group that owns the biggest average value consists of the Master Target Consumers for the business. This result would become the best suggestion for the business to adjust its strategies and to upgrade the productivity efficiency and create higher profit. As to the second research topic, we focused on finding the best corresponding characteristics attributes of the Brand Music for the Brand Log.
