Abstract We propose a method for actively controlling the frequency of an optical frequency comb (OFC) using sum-frequency generation (SFG) with a nonlinear crystal. For the first time, OFC generation was experimentally demonstrated via sum-frequency

A general object detector has a high misdetection rate for small objects. Although many small-object detectors consider the insufficient representation of objects, their performance in detecting very tiny objects with a strong similarity to other obj

The increasing computational demands of Deep Reinforcement Learning (DRL) models, particularly for embedded systems in autonomous vehicles and drones, present significant challenges owing to their extensive neural network complexities. Previous DRL c

We consider a problem of retrieving the extreme value among sensed data under deadline constraints in wireless sensor networks with potential applications to alarm systems. The sensed data is mapped to a score which we adopt as a unified measure of t

The meaning of intelligent systems has changed over time. Traditionally, it refers to an intelligent ruled-based context aware system, but nowadays, it is more often referred to as a deep learning intelligent system. Since these two intelligent syste

Multi-agent RL is a process of training the agents to collaborate with others. We argue that an additional 'reality gap' in the system aspects occurs when applying sim2real to the multi-agent RL, especially when performing the 'transferred' collabora

For the past decade, wireless sensor networks have focused primarily on data collection. As a result the network topology for these systems was usually heavily centralized. However, for these networks to form a full system, the introduction of proper

In this paper, we presented the analysis results on the characteristics of pulsed-LFM signal and pulsed-NLFM signal about the bandwidth, time-bandwidth product and auto correlation. And the calculation methods for actual necessary bandwidth of freque

In this paper, unmodulated pulse radar and four types of BPSK communication interference signal were designed to show the possibility of radar interference effect analysis using simulation. To verify this, the results of the interference impact measu
