1. The theory of the unfocused clear zone eye is extended to cover cases where rays are partially focused upon the receptor layer. 2. Light is admitted through facets according to a Gaussian distribution of angle of incidence defined with respect to the axis of the facet. 3. The same light crosses the clear zone in an average direction related to its direction of origin outside the eye, so that...

We introduce a method for detecting whether two users are engaged in focused interaction using a windowed correlation measure on their acoustic signals, assuming that a continued exchange of verbal turns contributes to anticorrelation of acoustic activity. We tested our method with manually annotated transitions between focused and unfocused interaction stemming from experiments on AR-based coo...

Framed in a cognitive approach to task-supported L2 vocabulary learning, the present study used a pedagogical approach to investigate the relative effectiveness of tasks with different involvement loads on the vocabulary knowledge of Iranian EFL learners. The goal was to investigate the way that the construct of involvement load is related to the Input Hypothesis (Krashen, 1985) and the Output ...

this study was inspired by vanpatten and uludag’s (2011) study on the transferability of training via processing instruction to output tasks and mori’s (2002) work on the development of talk-in-interaction during a group task. an interview was devised as the pretest, posttest, and delayed posttest to compare four intervention types for teaching the simple past passive: traditional intervention ...

Synthetic Aperture Radar (SAR) equipment is an all-weather radar imaging system that can create high resolution images by means of utilising the movement of the flying platform. Accurate knowledge of the flown trajectory is essential in order to get focused images. Recently SAR systems are becoming more used on smaller and cheaper flying platforms like Unmanned Aerial Vehicles (UAV). Since UAVs...
