A 200Mbps 0.02nJ/b dual-mode inductive coupling transceiver for cm-range interconnection
No full textA 200Mbps 0.02nJ/b dual-mode inductive coupling transceiver is proposed for cm-range inductive coupling interconnection. The parallel capacitor combined with the TX inductor enhances the transmitted signal slew rate so that it increases the transmission distance by twofold. The proposed inter-symbol interference (ISI) reduction scheme of the transmitter improves data rate up to 200Mbps. And the proposed pulse generation scheme allows the transceiver to consume only 0.02nJ/b energy. The transceiver consumes 0.012 mm 2 in a TSMC 0.25um CMOS process.N

We hypothesize that machine learning of preoperative biometric data obtained by the As-OCT may be clinically beneficial for predicting the actual ICL vault. Therefore, we built the machine learning model using Random Forest to predict ICL vault after surgery.
This multicenter study comprised one thousand seven hundred forty-five eyes of 1745 consecutive patients (656 men and 1089 women), who underwent EVO ICL implantation (V4c and V5 Visian ICL with KS-AquaPORT) for the correction of moderate to high myopia and myopic astigmatism, and who completed at least a 1-month follow-up, at Kitasato University Hospital (Kanagawa, Japan), or at B&VIIT Eye Center (Seoul, Korea).
This data file (RFR_model(feature=12).mat) is the final trained random forest model for MATLAB 2020a.

Image-based modeling of urban buildings using aerial photographs and digital maps
No full textA VR (virtual reality) simulator which is used for helicopter simulations requires a virtual environment of real world urban areas. However, real urban environments are continuously changing. It is necessary to develop a modeling method that makes direct use of GIS (geographical information system) data which is updated periodically. A flight simulation needs to visualize not only buildings in the near distance but also a large number of buildings in the far distance. We propose a method for modeling urban environments from aerial images and digital maps with relatively little manual work. An image-based method is applied to the urban modeling that considers the characteristics of Korean cities. Buildings in the distance can be presented without creating a large number of polygons. The proposed method consists of a pre-processing stage that prepares the model from the GIS data and a modeling stage that creates the virtual urban environment. The virtual urban environment utilizes the height map of buildings. © 2006 The Authors. Journal compilation © 2006 Blackwell Publishing Ltd
Representation of urban buildings using modified relief mapping
No full textThis paper describes the real-time mapping displacement of buildings onto the polygon model of base terrain of geo-spatial information. The buildings are represented as height maps, leading to low memory requirements and not involving changes of the original geometry (i.e., no vertices are created or displaced). The displacement of buildings is mapped toward the protruding direction. The base of texture which represents the ground in topography is correctly mapped onto base polygon without any distortion. This approach can exhibit the correct occlusions between buildings and ground due to parallax and correct self-occlusion
A 200-Mbps 0.02-nJ/b Dual-Mode Inductive Coupling Transceiver for cm-Range Multimedia Application
No full textA 200-Mbps 0.02-nJ/b dual-mode inductive coupling transceiver is proposed for cm-range multimedia application. The inductive link geometry and the advantage of the pulse-based inductive coupling are explained. In this paper, the parallel capacitor connected with the TX inductor, the intersymbol interference (IST) reduction scheme, and the pulse generation scheme are newly proposed. The parallel capacitor connected with the TX inductor increases the transmitter impedance so that it enhances the transmission distance by twofold, and the ISI reduction scheme pushes data rate up to 200 Mbps. Moreover, the pulse generation scheme reduces the energy consumption as low as 0.02 nJ/b. Maximum data rate and energy consumption are achieved in simulation. The transceiver occupies 0.012 mm(2) in 0.25-mu m CMOS process.N
