Research on Acquisition Probability of the Visible Light Reconnaissance Equipment to Ground Targets
The detection probability of visible light reconnaissance equipment is one of key indexes to assess the performance of the system. The detection probability is determined by many factors, such as atmospheric visibility, target-background contrast, target size and distance, solar elevation angle etc. Based on the detection probability model of the visible light reconnaissance equipment to gain t...
متن کاملPiezoelectric energy harvesting system for volcanic seismic acquisition equipment
In this paper it is presented a volcanic seismic acquisition equipment that has been developed together with an energy harvesting system, based on piezoelectric elements, in order to work in autonomous conditions. The energy harvesting system has been developed to convert the wind or marine currents energy into electrical energy through a new method based on piezoelectrics. For the deployment o...
متن کاملA Dynamical System Approach to Research in Second Language Acquisition
Epistemologically speaking, second language acquisition research (SLAR) might be reconsidered from a complex dynamical system view with interconnected aspects in the ecosystem of language acquisition. The present paper attempts to introduce the tenets of complex system theory and its application in SLAR. It has been suggested that the present dominant traditions in language acquisition research...
متن کاملImproving Performance of Mining Equipment Through Enhancement of Speed Factor: A Case Study (Research Note)
Loading and hauling machineries are highly capital intensive equipment to procure, operate and maintain in surface mining operation. It must be borne in mind that with this huge and capital-intensive equipment, every second of its life time is absolutely important from the production and productivity point of view. As such, it is imperative to optimize the overall cycle time and speed factor of...
