In this paper, we present two novel memetic algorithms (MAs) for gene selection. Both are synergies of Genetic Algorithm (wrapper methods) and local search methods (filter methods) under a memetic framework. In particular, the first MA is a Wrapper-Filter Feature Selection Algorithm (WFFSA) fine-tunes the population of genetic algorithm (GA) solutions by adding or deleting features based on uni...

This paper proposes a computable, tone-driven method to model phrasal pitch movements in standard Chinese by (1) formulating physical constraints for phonetic control mechanisms, (2) de ning four phrasal tones quanti ed by model parameters for generating phrasal tunes, and (3) forming phrasal pitch movements by mapping lexical tones onto phrasal tunes. Several experiments con rm the method's va...

This paper presents the results of a study of the intonation of negative sentences in a corpus of spontaneous interactive English speech. First, we found more instances of a high pitch accent marking the negative morpheme or auxiliary suffixed with contracted not than has been found in other interactive corpora. Only forms of the auxiliary do with contracted negation showed any likelihood to be...

There is a range of tempos within which listeners can identify familiar tunes (around 0.8 to 6.0 notes/s). Faster and slower tunes are difficult to identify. The authors assessed fast and slow melody-identification thresholds for 80 listeners ages 17-79 years with expertise varying from musically untrained to professional. On fast-to-slow (FS) trials the tune started at a very fast tempo and sl...

The Tevatron is a single beam pipe machine which contains both protons and anti-protons for HEP. This poses a challenge for measuring betatron tunes because of the possibility of contamination from the other species. In order to overcome this problem, stripline type structures are usually used because they are directional by construction or for the case of the 21.4 MHz Schottky system, a clever...
