the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...
In this work, we study the problem of supervisory control networked discrete event systems. We consider lossy communication channels with bounded network delays, for both channel and observation channel. By a model transformation, transform supervisor synthesis into classical (non-networked) (for non-deterministic plants), such that existing tools can be used synthesizing supervisors. particula...
This study proposes to recognize a user’s intentions in selecting from a set of machine-controlling commands by measuring his/her brainwaves. Our strategy is to convert a multiple-choice decision into yes-no decisions. For example, in a task of dialing assistance, our system prompts the user to select from each of the digits, and then analyzes his/her brainwave to determine if each digit is wha...

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
در این پایان نامه اثر علیت بر مسایل ترکیب توام کدینگ منبع و کانال(jscc) برای ارسال ویدیو در در کانال بیسیم بررسی میگردد. ابتدا کارایی روش jscc بر روی کدینگ ویدیو سری h ، h.264 در کانال بی سیم بررسی می شود. در این روش، بر اساس نرخ بیت ارسال و همچنین اطلاعات علّی وضعیت کانال در دسترس فرستندهcsit) causal) که به واسطه فیدبک در دسترس آن قرار می-گیرد. نرخ بیت بهینه به کدینگ منبع و کانال اختصاص داده می...
The effectiveness of existing control designs for bioassistive, exoskeletal devices, especially in highly uncertain working environments, depends on the degree of certainty associated with the overall system model. Of particular concern is the robustness of a control design to large-bandwidth exogenous disturbances, time delays in the sensor and actuator loops, and kinematic and inertial variab...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
