First we modify the basic (binary) context-tree weighting method such that the past symbols x1 D; x2 D; ; x0 are not needed by the encoder and the decoder. Then we describe how to make the context-tree depth D infinite, which results in optimal redundancy behavior for all tree sources, while the number of records in the context tree is not larger than 2T 1: Here T is the length of the source se...

The total variation minimization method for deblurring noise is shown to be effective in increasing the resolution in a contrast source inversion approach to index reconstruction from measured scattered field data. The main drawback is the presence of an artificial weighting parameter in the cost functional, which can only be determined through considerable experimentation Therefore, we introdu...

Quantitative assessment is the most important means to identify hazard potential and manage risk for an industrial process. The implement of quantitative assessment in the early stage will help to develop inherently safer process, eliminating the hazard and reduce the possibility of accidental chain events and the magnitude of consequences. In this paper, after reviewing the presently available...

where , , , and are the weights of different relevant physical quantities. The weighting matrices Q, R, and N were easily determined by converting the performance index (3) into standard form (2). After knowing the weighting matrices and state equations (1), we obtained the optimal state feedback gain K by solving the Riccati equation (Naidu, 2003). An optimization procedure, whose objective wa...

A new t~ature evaluation index based on fuzzy set theory and a connectionist model for its evaluation are provided. A concept of flexible membership function incorporating weighting factors, is introduced which makes the modeling of the class structures more appropriate. A neuro-fuzzy algorithm is developed for determining the optimum weighting coefficients representing the feature importance. ...

Our novel quality index is based on citations from international search reports and provides internationally comparable, quality-adjusted figures for applications made under the Patent Cooperation Treaty (PCT). We show that China’s recent patent expansion has taken place to the detriment of patent quality. Weighting national PCT counts with our index reveals a widening gap between the technolog...

Standard indicators of wellbeing such as the QALY for health and GDP per capita for economic development have been increasingly regarded as being too narrow in focus. There is a need to develop multidimensional measures of wellbeing that encompass the full range of factors that make life worth living. This study is part of a project that aims at developing a multidimensional index based on Sen'...

The green evaluation of urban power distribution network is the main reference basis for grid transformation and upgrading. Based on this, this article constructs a comprehensive index system from four dimensions supply side, consumer platform area related policies; To comprehensively consider difference relevance indicators, paper adopts order relationship analysis method CRITIC weighting subj...

Many common multidimensional indices take the form of a ‘composite indicator’ or a weighted average of several dimension-specific achievements. Rankings arising from such an index are dependent upon an initial weighting vector, and any given judgment could, in principle, be reversed if an alternative weighting vector were employed. This paper examines a variable-weight robustness criterion for ...

Optimum weighting ratios of maternal:direct EBV for litter size using an animal model were examined to achieve maximum genetic improvement (direct plus maternal response). Stochastic simulation of a 120-sow herd over a 10-yr period of selection was used (20 replicates). Directional selection was based on a merit function of maternal and direct EBV for first-parity litter size. Optimum weighting...
