چکیده
Methods of Measuring Mental Ability The simplest method of assessing mental ability is, of course, to ask questions, award marks and to compare the marks gained by one person with the marks gained by others. Its simplicity, range of application and possible refinements are the chief assets of this method and its chief defect is that the marking, however conscientiously it is carried out, remains arbitrary. The persons examined are really classified according to their ability to please the examiner and though this involves mental ability, training is also essential. A more reliable method of assessing mental ability is to use a standard group of problems which persons of average ability, without previous training, are just able

متن کاملSeparation of Carbon Dioxide from Natural Gas by Matrimid-Based Mixed Matrix Membranes
Spherical MgO nanoparticles and Flake-like clay minerals modified with polyaniline (PAni) are applied in Matrimid in order to fabricate mixed matrix membranes (MMMs) having improved gas separation performance. The CO2 permeability, CO2/CH4 selectivity and CO2-induced plasticization pressure of MMMs are assessed at 4-30 bar feed pressure. The chemical structure, morphology and thermal properties...

متن کاملAn Experimental Investigation on Fracture Analysis of Polymer Matrix Composite under Different Thermal Cycling Conditions
Fracture analysis of glass/epoxy composites under different thermal cycling conditions is considered. Temperature difference, stacking sequence, fiber volume fraction and number of thermal cycles are selected as the experimental design factors. The Taguchi method is implemented to design of the experiment and an apparatus is developed for automatic thermal cycling tests. The tensile tests are d...
متن کاملConstructing and Validating a Q-Matrix for Cognitive Diagnostic Analysis of a Reading Comprehension Test Battery
Of paramount importance in the study of cognitive diagnostic assessment (CDA) is the absence of tests developed for small-scale diagnostic purposes. Currently, much of the research carried out has been mainly on large-scale tests, e.g., TOEFL, MELAB, IELTS, etc. Even so, formative language assessment with a focus on informing instruction and engaging in identification of student’s strengths and...
متن کاملStudy of Gas Environment Impacts on Volumetric Coal Matrix Changes
The Outburst can be defined as a sudden release of coal and rock accompanied by large quantities of gas into the underground coal mine workings which represents a major hazard in underground coal mines. Gas drainage has been proven to be successful in reducing outburst hazards by decreasing the in-situ gas pressure. One of aspect of gas drainage from coal seams is coal matrix volume changes. Cu...
