testing as a general trait of social life has received a great deal of attention by many language teachers and scholars. throughout history, people have been tested to prove their abilities and experiences or to confirm their capacities. many authorities have said that assessment and instruction should be integrated as a single and inseparable activity which seeks to understand development by a...

in the past decades, we have witnessed a renascence of interest in vocabulary assessment (bachman, 2000). however, most researchers have focused on testing breadth rather than depth of vocabulary or receptive-productive dimensions of vocabulary knowledge (read, 2000; nation, 2001; wesche & paribahkt, 1996). the present research investigates the predicting variables of vocabulary knowledge acros...

We present an effective depth perception assessment index for stereoscopic images using a phase-shift model. To be more specific, we use Gabor filter to compute the responses of left and right images respectively, and proposed a phase-shift model for computing disparity maps based on phase gradient and phase difference information. Then, quality score for depth perception is obtained by measuri...

background and aims. the aim of this clinical investigation was to compare clinical and microbiological effectiveness of adjunctive chx gel in the treatment of periodontitis. materials and methods. twenty-four subjects with localized or generalized moderate-to-severe chronic periodontitis underwent scaling and root planing. one tooth in each quadrant with a probing depth of >4 mm was chosen for...

The aim of this study was to compare the performance between young adults (n = 15), healthy old people (n = 10), and masters athletes (n = 15) using a depth sensor and automated digital assessment framework. Participants were asked to complete a clinically validated assessment of the sit-to-stand technique (five repetitions), which was recorded using a depth sensor. A feature encoding and evalu...

The reservoir-induced seismicity (RIS) at the Karkheh dam site with a reservoir capacity of about 7.4x109 meters is investigated. Based on the assessment of the seismicity of the dam site in equal time periods before and after reservoir impoundment, it was found that the number of earthquakes have been tripled after impoundment, while their magnitudes and focal depths become smaller. The averag...

Compared to traditional 2D image techniques, stereoscopic techniques provide additional information the binocular depth, which strongly enhances the immersion. However, it may also cause visual comfort problems because it is still not a perfect representation of natural human vision but to some extent an illusion. How to fairly evaluate and understand the QoE (Quality of Experience) of stereosc...

background: managing dental caries in young children is demanding due to the elusions present on the right diagnostic criteria for treatment. the present study evaluated the histological status of pulp tissues extracted from primary second molar with caries involvement. histological findings are correlated with clinical and radiographic assessment. materials and methods: simple experimental stu...
