study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
foreign policy takes root from complicated matters. however, this issue may be more truth about armenia. although the new government of armenia is less than 20 years, people of this territory are the first ones who officially accepted christianity. in very past times, these people were a part of great emperors like iran, rome, and byzantium.armenia is regarded as a nation with a privileged hist...
the issue of curriculum and syllabus evaluation and revision has been in center of attention right from when curriculum came into attention of educational institutions. thus everywhere in the world in educational institutions curricula and syllabi are evaluated and revised based on the goals, the needs, existing content, etc.. in iran any curriculum is designed in a committee of specialists and...
In Structure from Motion algorithms, the error in the estimated motion aaects each reconstructed 3D point in a systematic way. This paper attempts to isolate the eeect of the motion error (as correlations in the structure error) and shows theoretically that these correlations can improve existing multi{frame Structure from Motion techniques. Finally it is shown that new experimental results and...
This paper examines the robustness of correspondence{based approaches to structure from motion. Unlike earlier studies it is proven in an algorithm{ independent way, that small absolute errors in image displacements cause absolute errors in rotational motion parameters signi cant enough to lead to large relative errors in the determination of environmental depth. Even if the exact motion parame...
We investigate the camera geometry of lines parallel in the world. In particular, we formalize the known rotational constraints and add new linear constraints on camera position. The constraints on camera position do not require the cameras to be viewing the same lines, thus providing applications for occluded scenes and calibration of cameras for which fields of view do not intersect. The cons...
