摘要： Proposed is a three-dimensionally stacked multi-mode sensor for simultaneously detecting pressure and temperature. The multi-mode sensor includes a temperature sensor part including a first thin film transistor; and a pressure sensor part including a second thin film transistor and a piezoresistive layer stacked in a perpendicular direction on the temperature sensor part, the piezoresistive layer including a piezoresistive sheet. The multi-mode sensor can accurately detect pressure and temperature simultaneously without being affected by temperature changes.

摘要： Disclosed are an integrate-and-fire neuron circuit implemented to enable an integrate-and-fire operation with only a small number of devices by using bistable resistance characteristics of the same two heterojunction NPN devices, unlike a CMOS-based integrate-and-fire neuron circuit having a complex structure, and an operation method thereof. In one or more aspects, an integrate-and-fire neuron circuit and an operation method thereof can increase neuron integration in a system by implementing an integrate-and-fire operation of neurons using only three transistors and two capacitors, or two transistors, one resistor and one capacitor, can improve the efficiency of spiking neural network learning by controlling a fire threshold point of neurons through regulation of a gate voltage of the same two NPN devices, and can expect an increase in energy efficiency of the entire system through inhibition of excessive fire by implementing excitatory and inhibitory post-synaptic potentials.

摘要： A method of providing a texture motion effect in a multisensory media system includes generating a texture signal by using linear predictive coding (LPC) filters obtained by applying LPC to each of a column and a row forming a texture image selected from an input image and generating a texture motion by using a visual roughness of the texture signal and a depth speed of a camera.

摘要： The present disclosure relates to a tree-search based trajectory planning and resource management method and apparatus of an unmanned aerial vehicle base station. The tree-search based trajectory planning and resource management method of an unmanned aerial vehicle base station according to an embodiment of the present disclosure includes: decomposing an optimization problem of trajectory planning, user association (UA), resource allocation (RA), and power control (PC) related to the unmanned aerial vehicle base station into a time axis; managing resources by jointly optimizing variables of the UA, RA, and PC for an arbitrary location of the unmanned aerial vehicle base station; and obtaining the trajectory planning by obtaining position variables based on the obtained predetermined function value and a depth-first search (DFS) algorithm.

摘要： A tip-enhanced spectroscopy may include a substrate on which liquid containing an analyte is to be positioned, a tip extending from a fixed end to a free end adjacent to a location for the analyte, and a vibration source configured to harmonically vibrate the tip based on a preset natural frequency. The preset natural frequency may be a natural frequency of a tuning fork.
