Tomatoes are the most familiar and common greenhouse vegetable crop in Turkey, as well worldwide. Main whitefly species problematic greenhouses, where tomatoes grown primarily, is Bemisia tabaci Genn. (Hemiptera: Aleyrodidae) Mediterranean Region of Turkey. Serangium parcesetosum Sicard (Coleoptera: Coccinellidae) proved a coccinellid predator B. voracious feeder by several studies. The hypothe...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
This technical report addresses model-based interpolation of long signal gaps. It demonstrates that employing a modified autoregressive AR model, computed as a weighted sum of line spectral pair (LSP) polynomials, is more efficient computationally than using a conventional AR model, since longer signal gaps can be interpolated at reduced model order. Key-words: acoustic signal processing, audio...
This paper presents a novel algorithm which generates three-dimensional face point trajectories for a given speech le with or without its text. The proposed algorithm rst employs an oo-line training phase. In this phase, recorded face point trajectories along with their speech data and phonetic labels are used to generate phonetic codebooks. These codebooks consist of both acoustic and visual f...
In this paper, we examine the best domain to perform features interpolation in Distributed Speech Recognition (DSR) systems. We show that the only one domain where a performance gain can be achieved from the linear interpolation procedure is in the Line Spectral Frequencies (LSF) domain. A DSR scenario where the ITU-T G.723.1 codec is employed is also investigated. The recognition feature gener...
In this paper, a novel transcoding algorithm for the Selectable Mode Vocoder (SMV) and the G.723.1 speech coder is proposed. In contrast to the conventional tandem transcoding algorithm, the proposed algorithm converts the parameters of one coder to the other without going through the decoding and encoding process. The proposed algorithm is composed of four parts: the parameter decoding, Line S...
This paper presents a new scheme for developing a voice conversion system that modiies the utterance of a source speaker to sound like speech from a target speaker. We refer to the method as Speaker Transformation Algorithm using Segmen-tal Codebooks (STASC). Two new methods are described to perform the transformation of vocal tract and glottal excita-tion characteristics across speakers. In ad...
Expression of the platelet-derived growth factor alpha-receptor (PDGFalphaR) gene is tightly controlled in mammalian embryogenesis. A well established model system to study human embryogenesis is the embryonal carcinoma cell line Tera2. We have shown previously that retinoic acid-differentiated Tera2 cells express two PDGFalphaR transcripts of 6.4 kilobase pairs (kb) (encoding the full-length r...
