evaluating the quality and quantity of water resources is crucial for a sustainable development. one of the simplest methods that is able to indicate the conditions of water quality in a short period and at a low cost, compared with the physicochemical methods, is by using the biological water quality indices. identifying the contamination of water resources using biomarkers, especially indices...

storaging or transmission of speech signals at very low bit rate is a hot area in the field of speech processing. we used stochastic inter-frame interpolators and vector quantization (vq) as a new method for developing a high quality 1200 bps speech vocoder. the objective and subjecgtive test results show that performance of the new vocoder is compairable with 4800 bps standard vocoders (as celp).

ccurately evaluating stuttering symptoms in both children and adults who stutter is the first step in the treatment of stuttering. Around the time of "Diagnosogenic theory" researchers collected speech samples from a large number of children, and attempted the categorization and development of indicators for evaluating people who stutter (PWS). Two global disfluency measures were introduced: St...

abstract soil quality evaluation is an essential issue in soil management for agriculture and natural resource protection. soil quality indices are useful tools for determination and comparison of soils quality. using of principle component analysis in this study we selected 6 important properties as a soil quality minimum data set (mds) among 18 soil properties (tds). then, soil quality of agr...

Problem statement: Dialects of Thai are quite different in the speaking styles. Environmental noises play an important role in corrupting the communication speech quality. Two factors affect the coded speech in the present speech communication. It is necessary to investigate how the two factors influence on the speech compression. Approach: In this study, the Multi-Pulse based Code Excited Line...
