Vocabulary generation is the essential step in the bag-ofwords image representation for visual concept recognition, because its quality affects classification performance substantially. In this paper, we propose a hybrid method for visual word generation which combines unsupervised density-based clustering with the discriminative power of fast support vector machines. We aim at three goals: bre...

With ever increasing concerns on energy efficiency, energy diversification, and environmental protection, the development of electric vehicle (EV) technology has taken on an accelerated pace. The dream of having commercially viable EVs is becoming a reality. This paper identifies the uniqueness of EV drives, and hence provides an overview on the development of power electronic drives for EVs. R...

raven progressive matrices (rpms) and wechsler intelligence scale for children (wsic-r) are two common general intelligence measuring scales used in iranian high schools. in this paper the relationships between g factor scales and students’ reading comprehension, grammar, and vocabulary was examined by correlation and regression analysis. standard tests of grammar and vocabulary and cambridge k...

this study was conducted to compare the impact of two vocabulary learning techniques, namely context learning and translation learning, on vocabulary recall of sixty pre-university iranian learners of english as a foreign language. they were divided into two groups of high and low proficient. in regard to two vocabulary learning conditions, each group was divided into two subgroups of fifteen. ...

This paper proposes an approach to the secondary task in the TREC Genomics Track. We regard the task as identification of the sentences describing gene functions (i.e., GeneRIFs) and propose a method considering two factors: topicality and relevance. The former refers to the topicality of a sentence and is measured based on location information and word frequencies in the article. The latter re...

In this paper, we describe technology and experience with an experimental personal information manager, which interacts with the user primarily but not exclusively through speech recognition and synthesis. This device, which controls a client PDA, is known as the Personal Speech Assistant (PSA). The PSA contains complete speech recognition, speech synthesis and dialog management systems. Packag...
