testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
This study reports an experimental investigation on the impact behavior of elliptical concrete-filled steel tubular (CFT) columns subjected to lateral loading. A total five CFT columns, including one circular cross-section and four cross-sections, were tested using a horizontal-impact-testing system. The influences velocity, times, geometry dynamic response analyzed. results have shown that spe...
Methods: 4D LV endocardial function from cine cMR data in 12 NYHA Class III /IV Heart Failure (HF) patients with antero-apical aneurysms was compared against normal controls. The endocardial surface contours were extracted at each cardiac phase using Medviso Segment. An in-house plugin was used to compute a signed Hausdorff Distance (HD), establishing point-correspondences between endocardial s...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
This paper is concerned with the estimation of tra-jectories for accelerated motion from image sequences. Unlike in many other approaches, that assume linear trajectories, we propose a quadratic model that incorporates both velocity and acceleration. This model corresponds better to practical applications especially when the estimation is performed over several images, e.g., in motion-compensat...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
background: centre of pressure displacement is an indicator of postural control. children with cerebral palsy have poor postural control. one common intervention to enhance their balance is vestibular stimulation. the aim of this research was to investigate the effect of vestibular stimulation on cop parameters in children with cerebral palsy (3-10 years old). methods: this study was a randomiz...
The purpose of this study was to determine the reliability and validity of the GymAware optical encoder (Kinetic, Canberra, ACT) to measure displacement data (distance, peak velocity, mean velocity and time). Three GymAware sensors were attached to a Calibration Rig (CalRIG), a novel piece of technology engineered specifically for accurate calibration of dynamometry equipment. The CalRIG was pr...
