In recent years, Wireless Sensor Networks (WSNs) research has undergone a quiet revolution, providing a new paradigm for sensing and disseminating information from various environments. In reality, the wireless propagation channel in many harsh environments has a significant impact on the coverage range and quality of the radio links between the wireless nodes (motes). Therefore, the use of div...

Calibration is a crucial step to obtaining three-dimensional (3-D) measurement using video camera-based stereo systems. Approaches based on epipolar geometry are particularly appealing as there is no need to know the 3-D position of the control points a priori and because the solution is found by solving a set of linear equations through matrix manipulation. Indeed, all the parameters can be de...

the present study aimed at investigating whether vocabulary-learning strategies had any impact on the vocabulary learning of iranian efl learners. the participants of the study were 67 male and female undergraduate university students, majoring in english translation and english literature at islamic azad university, north tehran branch, who were taking “reading comprehension ii” course. in ord...

in order to confirm the effectiveness of language learning strategies in theiranian context in junior high schools, this study was designed to examine thepatterns of strategy use, the effects of strategy instruction on the students’ strategyuse, and the relationship between the participants’ strategy use and their englishachievement. to achieve this objective, 57 junior high school participants...

Evolution Strategies (ES) have recently been demonstrated to be a viable alternative to reinforcement learning (RL) algorithms on a set of challenging deep RL problems, including Atari games and MuJoCo humanoid locomotion benchmarks. While the ES algorithms in that work belonged to the specialized class of natural evolution strategies (which resemble approximate gradient RL algorithms, such as ...

Investigating the interactions of granular fertilizers with various types equipment is an essential part agricultural research. A numerical technique simulating mechanical behavior assemblies has advantage data trackings, such as trajectories, velocities, and transient forces particles at any stage test. The interaction parameters were calibrated to simulate responses in EDEM, a discrete elemen...

The development of NIRS calibration model as a rapid, precise, robust, and cost-effective method to estimate oil content in ground seeds of worldwide safflower germplasm collection grown under different agro-climatic conditions was the key objective of this research project. The oil content was measured by accelerated solvent extraction method in a total of 328 samples collected across 2004 (16...

accurate delivery of torque to implant screws is critical to generate ideal preload in the screw joint and to offer protection against screw loosening. mechanical torque-limiting devices (mtlds) are available for this reason. in this study, the accuracy of one type of friction-style and two types of spring-style mtlds at baseline, following fatigue conditions and sterilization processes were de...
