Then, the selective attention mechanism model is proposed to extract the salient gist features which showtheir relation to the expected performance in cross-corpus testing.Furthermore, the Chirplet time-frequency atoms are introduced to the model. By forming a complete atom database, the Chirplet can improve the spectrum feature extraction including the amount of information. Samples from multiple databases have the characteristics of multiple components. Hereby, the Chirplet expands the scale of the feature vector in the timefrequency domain. Experimental results show that, compared to the traditional feature model, the proposed feature extraction approach with the prototypical classifier has significant improvement in cross-corpus speech recognition. In addition, the proposed method has better robustness to the inconsistent sources of the training set and the testing set.展开更多

In this study, four global food brands＇ advertisements including cultural codes, locality, and globality have been randomly selected and analyzed. These advertising messages have been analyzed at an intercultural level from visual semiotics perspective. It has been tried to determine the ＂local＂ approaches of global brands by revealing the ＂intercultural＂ dimension transferred through visual and linguistic signs in the advertisements which we reselected with an eclectic method.展开更多

We also know that, it comprises one major section of the standard and TOEFL （Test of English as a Foreign Language） tests. Taking into account its importance and the problems which EFL learners have answered them, I get motivated to uncover some of the test-taking strategies which they employ to answer multiple-choice reading comprehension questions when dealing with familiar versus unfamiliar topics. To get a better conclusion, I choose 20 advanced male and female candidates whose English proficiency is at an acceptable level and at least at the same age level, and they major in English language from different colleges and universities. They are given two reading comprehension passages （familiar and unfamiliar）, each one with five final questions and allotted time to answer the questions. Two main instruments in this study are a retrospective think-aloud protocol and a semi-structured interview. The results of the reading comprehension tests and interview part revealed that advanced learners＇ high scores in the familiar topic were not because of their strategy use but because of their high linguistic and background knowledge on the topic. I also concluded that the number, kind, and sequence of strategies employed, were greatly dependent on the degree of testees＇ familiarity on the topic. In other words, test-takers used more strategies to compensate for their lack of linguistic knowledge.展开更多

In our approach, place name candidate is located according to a rational forming assumption, then SVMs based identification strategy is used to distinguish whether one candidate is true place name or not. Referring to linguistic knowledge, basic semanteme of a contextual word and frequency information of words inside place name candidate are selected as features in our methodology. So dimension in the feature space is reduced dramatically and processing procedure is performed more efficiently. Result of open testing on unregistered place names achieves F-measure 83.25 in 8.17 million words news based on this project.展开更多

The current emphasis in computer game AI is improving the quality of opponent AI. Our research question reads: How can unsupervised online learning be incorporated in Computer Role Playing Game(CRPG) to improve the strategy of the opponent AI? Our goal is to use online evolutionary learning to design strategies that can defeat the opponent. So we apply a novel technique called dynamic scripting that realizes online adaptation of scripted opponent AI and report on experiments performed in a simulated CRPG to assess the adaptive performance obtained with the technique.展开更多

First, best geometric features are selected for each location and each resolution, in order to reduce ambiguity in matching during image registration. The best features are obtained by solving an energy minimization problem, which requires the features to be distinctive around the neighboring points and consistency across training samples. Secondly, the set of active points is hierarchically selected based on their saliency and consistency measurements during registration, which helps to produce accurate registration results. Finally, by incorporating those learned results into the framework of HAMMER, great improvement in both real data and simulated data is achieved.展开更多

Cognates, words which area like beyond two or additional languages in some fields signify an attention-grabbing, illuminating, and crucial facet of foreign or second language learning and research. Forty-five （males and females） participants have been randomly chosen and participated in the experiment in Islamic Azad University, Zanjan, Iran, in 2014-2015 school year. The participants＇ age was between from 18 to 28, with a mean age of 21.5 years. The materials were divided into two groups which include 30 true cognates and 30 false cognates words from 300 words by doing CVR （content validity ratio） and CVI （content validity index） （Lawshe＇s table with index of 88% and 82% respectively） for being reliable and valid. These words have been taught to them, after a week, a test has been prepared about those words. According to the results of T-test for comparing the average marks of learning in every two groups can be said that there is a meaningful difference between the scores. The results show that the students learned true cognate words better than the false cognate words. The results of this investigation conjointly make sure the expectations that cognate-based instruction can absolutely impact in second language acquisition.展开更多

A real seamless wireless mobile environment is only realized by considering vertical and horizontal handoffs together. One of the major design issues in heterogeneous wireless networks is the support of Vertical Handoff （VHO）. VHO occurs when a multi-interface enabled mobile terminal changes its Point of Attachment （PoA） from one type of wireless access technology to another, while maintaining an active session. In this paper we present a novel multi-criteria VHO algorithm, which chooses the target NAT based on several factors such as user preferences, system parameters, and traf- tic-types with varying Quality of Service （QoS） requirements. Two modules i.e., VHO Neces- sity Estimation （VHONE） module and target NAT selection module, are designed. Both modules utilize several ＂weighted＂ users＇ and system＇s parameters. To improve the robust- ness of the proposed algorithm, the weighting system is designed based on the concept of fuzzy linguistic variables.展开更多

The author considers music as areflection of worldview and religion. For this purpose the author uses a method of comparison of a mythological picture of the world and properties of musical language. An important element linking the two areas is vertical. In mythology, this is turning the world on several floors in which the world of people occupies the middle one. At the level of music--it is the vertical of overtone sound row. The initial timbre ideal of this tradition are th esounds of throat singing which are associated with the vertical of the universe and consciousness used as an important formative structure of the World Model. In the article the author considers a materialization of musical consciousness in musical instruments. For this purpose, eight instruments under different names are selected andpresented in musical cultures of people. This allows the author to create the card of geographical distribution of tengri consciousness.展开更多

The methodology employed is a socio-lin some randomly selected urban centers in Cameroon for example, Buea, Bamenda, Kumba, guistic survey of etc.. The results suggest among other things： （1） that Cameroon is a highly multilingual country with over 280 home languages and （2） that while English is the language for Anglophone education, Pidgin English is actually the predominant language and the first language for most Anglophones. Based on these findings, the author proposes Pidgin English as the choice language for early education in Anglophone Cameroon （the southwest and northwest regions）. Pidgin English is the only language which expresses Cameroonian reality. It is spoken by more than 70% of the population. It is the only language that is not associated with a particular tribe, religion, or with a specific colonial government.展开更多
