Fractured carbonate reservoirs account for 25% of world’s total oil resources and for 90% of Iranian oil reserves. Since calcite and dolomite minerals are oil wet, gas oil gravity drainage (GOGD) is known as the most influencing production mechanism. The most important issue within gas injection into fractured media is the channeling problem which makes the efficiency of gas injection process e...
Dynamic simulation has great potential as a tool for teaching physics and science in general. This paper describes a family of simulators that have been developed to teach several topics in physics including circular motion, collisions, energy storage, and heat flow. These simulators provide students with laboratories for experimenting with the phenomena in the context of realworld situations s...
The paper specifies the development of a toolkit to run synthetic science laboratories. The aim was to facilitate collaborative experimenting for problem-based learning in a virtual lab. The goal was to demonstrate virtual experimenting by use of interactive 3D visualization and simulation. Technology was developed over six years and in part designed in explicit accordance to didactic models. F...
in this study, we have theoretically investigated the effect of electron stopper layer on internal temperature distribution of high performance vertical cavity surface-emitting laser emitting at 1305 nm. simulation software pics3d, which self-consistently combines the 3d simulation of carrier transport, self-heating, gain computation and wave-guiding, was used. simulation results show that cha...
in the present study, the kinetics of biodiesel production through transesterification of brassica carinata oil with methanol in the presence of potassium hydroxide is investigated by kinetic monte carlo simulation. the obtained results from simulation agree qualitatively with the existing experimental data. the kinetics data for each step of suggested mechanism are confirmed by simulation. by ...
background: simulation can be used for educating, evaluating and assessing psychometric properties of an instrument. the aim of this study was to contextualize and assess the validity and reliability of the interprofessional collaborative assessment tool (icar) in an iranian context using simulation. methods: in this descriptive study, contextualization of the icar was assessed through severa...
in the present study, a new modelling technique was developed for the modelling and analysis of hyperchaotic systems using an expert system based on wavelet decompositions and the adaptive neuro-fuzzy inference system (anfis). the success and superior properties of this new expert system were shown by applying the hyperchaotic chen system which is a hyperchaotic system. the obtained expert s...
the purpose of the present study was to investigate the latent pattern underlying reading ability . some 272 male and female participants. english majors at the ba level , participated in the study. two valid tests were used in this study, the reading test developed exclusively for the purpose of this project and academic reading section of ielts. to investigate the possible latent underlying...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
this study explored reading strategy use of tefl ma students when they read academic research articles in english. the purpose of this study was to investigate how this group of readers typically approaches reading academic research articles related to their field of study, and also what they do in reading such research articles. the aim of the present study was bilateral. first, the researcher...
