In this article, researchers set out to discover the metadiscourse markers in research articles written by both native and non-native English speakers. To this end, a total number of twenty research articles published by Iranian and native English speakers in highly reputed journals on Arts and Humanities domains were randomly selected from major databases including Science Direct, Noormagz, an...

The purpose of this study was to examine Cook’s (2003) ‘multiple competence’ by investigating backward pragmatic transfer (from L2 [English] to L1 [Persian]) in refusals to invitations. It explored participants’ frequency and content of refusal strategies in L1 regarding the status (i.e., power and distance) of interlocutors and the proficiency level of EFL learners. The participants were Persi...

the present research is aimed at investigating how the politeness of the speakers of urdu is influenced by their relative social status in society. the researcher took politeness theory of brown and levinson (1978, 1987) as a model. to observe politeness of urdu speakers, speech act of apology with different strategies was selected. a discourse completion task (dct) was used as an instrument to...

In this paper, we present an active audition system for humanoid robot “SIG the humanoid”. The audition system of the highly intelligent humanoid requires localization of sound sources and identification of meanings of the sound in the auditory scene. The active audition reported in this paper focuses on improved sound source tracking by integrating audition, vision, and motor movements. Given ...

ABSTRACT This paper presents an overview of the knowledge afforded man from research into personality. Approaching his topic from a position valuing the study of persons from complementary psychological perspectives, the author attempts to derive some conclusion about human behavior and personality. He discusses the findings that there is basic continuity in personality; each person is capable ...

A particular feature of most species of bats is that they use echolocation, or ‘active sensing’, in which pulses of acoustic energy are emitted and the resulting echo is resolved into an ‘image’ of their surrounding environment. This is used to detect objects and to locate food resources such as flying insects. Previous work has taken inspiration from the process of echolocation to develop the ...

This article presents a physical biology approach to understanding organization and segregation of bacterial chromosomes. The author uses a “piston” analogy for bacterial chromosomes in a cell, which leads to a phase diagram for the organization of two athermal chains confined in a closed geometry characterized by two length scales (length and width). When applied to rod-shaped bacteria such as...

In this paper, we show how to use audio to supervise the learning of active speaker detection in video. Voice Activity Detection (VAD) guides the learning of the vision-based classifier in a weakly supervised manner. The classifier uses spatio-temporal features to encode upper body motion facial expressions and gesticulations associated with speaking. We further improve a generic model for acti...

In the last few years, different linear and non-linear control techniques have been applied by many researchers on the vehicle suspension system. The basic purpose of suspension system is to improve the ride comfort and better road handling capability. Therefore, a comfortable and fully controlled ride can not be guaranteed without a good suspension system. The suspension system can be categori...

We propose a concept of active diagnosis that differs from the conventional passive (i.e. event-driven) diagnosis in temporal (diagnosis is carried out by always monitoring normal condition as opposed to identifying faulty only when abnormal condition is detected) sense as well as spatial (diagnosis is carried out by agents distributed in the sensor network) sense. As one way of realizing activ...
