Mid-infrared atmospheric absorption bands centered at 4.3 $\mu\mbox{m}$ are applied in target detection. Image simulation, as an important tool for the adaption and optimization of a sensor, ought to be conducted for the development of instruments using this spectral range. In this paper, a top-of-atmosphere (TOA) image simulation method is proposed, and this method is tested on two bands of the...
An analytical method is introduced in the paper for the static characteristics of the cylindrical-spherical joint surfaces, based on fundamental parameters of the joint, and which has validated by the comparison between a case study and experimental results. The results show that this method is correct and feasible.
Golf Swing is one of the most difficult techniques in sports to perfect, and a smooth swing can't be achieved without a correct process of bodyweight transfer between the feet during the motion, which is known as weight shift in golf. As pointed out by various professional players and coaches, a proper weight shift is critical in hitting a shot with good accuracy and range, and therefore it would...
Text clustering, an important part of the machine learning and pattern recognition, has extensive applications in the field of natural language processing. In this paper, a method is given to improve the classic TFIDF algorithm on its shortcomings. This paper classifies the text through Naive Bayesian classifier. And uses the iterative algorithm to optimize the selection of feature words, and then...
In this paper, we investigate the machine learning based strategies for dynamic channel selection in Cognitive Access Points (CogAPs) of WLANs. We employ Multi-layer Feedforward Neural Network (MFNN) models that utilize historical traffic information from network environment for learning the influence of spatio-temporal-spectral factors on the network and then predicting future traffic loads on each...
One of the early applications of cognitive networking in wireless networks is the problem of dynamic channel selection in multi-channel wireless networks. Dynamic channel selection requires gathering past and current traffic across multiple channels and predict future traffic loads on each of the channels for deciding best channel for the Access Point (AP) to operate on for serving wireless clients...
