Abstract A new demapper is presented for communication channels that can be modeled with Goggle and Accessories data-dependent noise on the received symbols.This includes optical and satellite channels with various types of distortion.The demapper incorporates the covariance information of the received symbol clusters to capture noise variation acr
Vision-based sensors such as LiDAR (Light Detection and Ranging) are adopted in the SLAM (Simultaneous Localization and Mapping) system.In the 16-beam LiDAR aided SLAM system, due to the difficulty of object detection by sparse laser data, neither the grid-based nor feature point-based solution can avoid the interference of moving objects.In an urb
The prediction of the trends of stocks and index prices is one of the important issues to market participants.Investors have set trading or fiscal strategies based on the trends, and considerable research in various academic fields has been studied to forecast financial markets.This study predicts the trends of the Korea Composite Stock Price Index
The experiment was conducted at Bangladesh Agricultural Research Institute farm, Joydebpur, Gazipur during March to July 2007 to evaluate the bioefficacy of some plant extracts in controlling Cercospora leaf spot of mungbean.Six indigenous plant species i.e.Neem leaves extract (1:4 w/v), Garlic cloves extract (1:5 w/v), Biskatali leaves extract (1:
The polycrystalline cubic boron nitride (PCBN) milling tool can be used in the mold industry to replace cemented 639 carbide tools to improve machining efficiency and quality.It is necessary to study the tool wear and failure mechanism to increase machining efficiency and extend tool life.Cr12MoV is used to analyze the failure form of PCBN tools in
