This paper reports the comparative evaluation of several speech F0 evaluation algorithms over a wide database of laryngographlabeled speech. Included are several classic algorithms that are available in software on the net, as well as two new algorithms that offer greatly reduced error rates. Particular attention is given to the methodology of evaluation.

This work introduces AM-FM, a semantic framework for machine translation evaluation. Based upon this framework, a new evaluation metric, which is able to operate without the need for reference translations, is implemented and evaluated. The metric is based on the concepts of adequacy and fluency, which are independently assessed by using a cross-language latent semantic indexing approach and an...

chitosan is a polysaccharide derived from chitin by n-deacetilation, which has the property of gel formation. the objective was to develop a chocolate milk beverage using modified (hydrogel) chitosan as a thickening agent, and to make a sensory and rheological evaluation of this beverage. in the sensory evaluation an acceptability and comparative test with 50 local consumers was carried out, wi...

This review highlights general toxicology concerns caused by formulation differences between generic and innovator drugs. It underscores the importance of a scientific, clinically oriented, evidence-based comparative safety evaluation procedure for generic drugs and discusses representative case studies from a pharmacology-toxicology perspective. For consideration by generic drug industry stake...

The new version of the system for a comparative study of image processing algorithms named PICASSO 2 is presented. We demonstrate its use in comparative evaluation of three energy minimizing methods (by Mumford-Shah, Gеman-Reynolds and the method with piecewise-linear energy minimizing function). The testing includes quantitative and qualitative estimation of noise reduction property. Also thre...

While there are a considerable number of software engineering methodologies for developing multi-agent systems, not much work has been reported on the evaluation and comparison of these methodologies. This paper presents a comparative analysis of five well-known MAS-development methodologies. The comparison is based on a feature analysis framework published previously [1]. This framework allows...

Does the socioeconomic status (SES) that one's (ego's) network members (alters) occupy indicate social resources or social comparison standards in the dynamics of health across culture? Using nationally representative data simultaneously collected from the United States and urban China, this study examines two competing theories-social capital and comparative reference group-in the two societie...
