Abstract: Disclosed herein is a pulse repetition rate multiplier including a photonic integrated circuit (PIC) including cascading Mach-Zehnder interferometers (MZIs). An input may be connected to one end of the PIC and an output may be connected to the other end of the PIC such that a signal from the input runs through the cascading MZIs and out the output. The input may be configured to receive an input pulsed signal and the output may be configured to output a repetition rate multiplied signal. Advantageously, using a PIC as opposed to an optical fiber-based pulse rate multiplier allows for accurate fabrication of a pulse repetition rate multiplier configured to accept higher frequency pulsed signals.

Abstract: Provided is a pedo-transfer function (PTF)-based method for predicting a target soil property. Based on the collection of a multi-source soil dataset and environmental variables, a dataset containing all measured information is divided. Second-level regions are obtained by zoning according to the spatial variation in soil properties. An optimal independent variable set of PTFs in different regions is obtained by screening. Then, linear fitting and nonlinear fitting of the PTFs are performed for different zones separately. By comparing the accuracy of different functions between different zones, optimal PTFs oriented toward sampling sites are selected, so as to build a database including soil sampling sites. Further, regional independent variable layers are constructed by means of machine learning, to establish region-oriented PTFs; and a spatial distribution map of the target soil property and content for a target region is produced.

Abstract: An image recognition device involves successively extracting co-occurrence pairs in synchronization with a clock, setting a weighting for the portion connecting the input layer and the intermediate layer corresponding to the extracted co-occurrence pairs, and successively inputting a first vote to the input layer. Meanwhile, the intermediate layer adds and stores the successively inputted number of votes. By continuing this operation, a value the same as if a histogram were inputted to an input layer is achieved in the intermediate layer, without creating a histogram. In this way, the image recognition device of this embodiment can perform image recognition while avoiding the creation of a histogram, which consumes vast amounts of memory. As a result of this configuration, it is possible to save memory resources, simplify circuits, and improve calculation speed, and achieve an integrated circuit suitable to an image recognition device.
