In the present work, the quantum theoretical calculations of the molecular structure of the 1-(1, 3-Benzothiazol-2-yl)-3-(thiophene-5-carbonyl) thiourea has been predicted and are evaluated using Density Functional Theory (DFT) in gas phase. The geometry of the title compound was optimized by B3LYP/6-311+G and B3LYP/6-311+G* methods and the experimental geometrical parameters of the title compo...

there is insufficient rigorous research examining which features of efl/esl learners’ writing can be improved through their awareness/knowledge of collocation. this study, therefore, addressed this issue and examined the effect of this awareness on iranian efl learners’ writing performance with respect to the specific features of each writing sub-component (i.e., content, organization, vocabula...

Error Analysis is one of the major topics in the field of second language acquisition research. Errors are an integral part of language learning. The learner of English as a second language is unaware of the existence of the particular system or rule in English language. The learner’s errors have long been interested for second and foreign language researchers. The basic task of error analysis ...

We investigate the uses and limitations of MFCC analysis for feature extraction from music files in the domain of genre recognition. Intra-genre and Inter-genre classification is explored. We implement a method of genre classification based on MFCC extraction, K-means clustering, and KNN analysis. We demonstrate the efficacy of our method through testing, yielding a 99% accuracy rate.

This study explored the move-step structure of Results and Discussion (R&D) section electronic engineering research articles (EERAs) written by Chinese Thai researchers. Two corpora, with each containing 12 R&D sections, were compiled for analysis reference to three frameworks Kanoksilapatham (2005, 2015) Maswana et al. (2015). In addition, variations in terms between two corpora examin...
