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...

Volumetric ultrasound imaging has been primarily used as a clinical tool to diagnose cardiac dysfunction. However, the modality still suffers from system complexity due to a large number of receive channels for volumetric reconstruction. The aim of the study was to numerically assess a cross-shaped sparse array with a dynamic transmit focusing method to reduce the system complexity and to compe...

this study aimed at investigating the effect of learners’ gender on their preferences for corrective feedback. learners’ prefer- ences which were investigated included the necessity, frequency, timing, type, method, and delivering agent of error treatment. to this end, a questionnaire was administered to a random sample of 100 participants (50 males and 50 females) studying english (efl) at shi...

introduction: feedback is very important in education and can help quality in the training process and orient the trainees in clinical contexts. this study aimed to assess the residents’ points of view about feedback in clinical education at shiraz university of medical sciences. methods: the sample of this study included 170 medical residents attending medical workshops in shiraz university of...

recent interaction studies havefocused on the relationship between interactional feedback and l2 development.despite the large body of knowledge in this regard, few studies have examinedlearners’ preferences for interactional feedback. besides, different findingshave been reported concerning learners’ preferences for feedback and none hasexamined the factors accounting for the variation in the ...

Thomas Szanto has recently argued that hatred could not be a fitting emotion because of its blurred focus. It thus cannot trace the properties intentional object. Although I agree with core Szanto?s account, would like to discuss two connected issues might importance. First, want address whether unfittingness anything do possibility hated person does identify what they are for. conclude if focu...

since the emergence of the process-oriented approach in second language writing instruction, the issues of writing instruction have been predominantly concerned with what and how error feedback should be given to the students’ writing. the present study investigated the effect of explicit corrective feedback on writing accuracy of iranian intermediate efl learners (n = 44) in hamedan islamic az...

Abstract In scanning acoustic microscopy (SAM) , the image quality depends on several factors like noise level, resolution, and interaction of waves with sample boundaries. The theoretical equations for reflection coefficient transmission are suitable plane boundaries but fail curved/rough We presented a finite element method-based modeling loss coefficients in SAM. A focused unfocused lens fla...
