With the development of microprocessors toward higher power, larger chip, and frequency, heat dissipation is one central issues. Thermal interface materials (TIMs), which are used between chip spreader sink, play an increasingly important role in microprocessor cooling. Currently, most research has primarily dealt with understanding thermal conductivity TIMs. For design, elastic compliance also because excellent can reduce contact resistance relieve warpage failure caused by stress...
Effective communication between multiple autonomous underwater vehicles (AUVs) is necessary for formation control. As the most reliable method, acoustic still has many constraints compared with radio communication, which affects effectiveness of Therefore, this paper proposes a control scheme AUVs under delay, packet discreteness and dropout. Firstly, delay estimated based on kernel density estimation method. To solve problem dropout, curve fitting method used to predict states AUV....
Many WLAN-based indoor localization techniques estimate a target's location by comparing received signal strength indicator (RSSI) with stored fingerprints. However, the collection of fingerprints is notoriously tedious and time-consuming. It challenging to reduce fingerprint recover absent data without introducing errors. In this article, new approach based on compressive sensing presented for recovering The hidden structure redundancy characteristics are revealed in Merging Matrix. spatial...
The problem of multiple autonomous underwater vehicles (AUVs) cooperative target hunting is an important research topic for its potential applications, including military and civil. This paper proposes a method based on formation control to improve the efficiency accuracy hunting. Firstly, AUVs run together search in large area where probably exists. At this stage, improved leader-follower algorithm used gather with desired formation. Then after recognition target, route planned pursuing...
In this paper, we systematically explore the environmental effects of export tax rebate rate reduction policy using China Industrial Enterprise Database, Pollution and Customs Import Export Database from 2005 to 2013. Our difference-in-difference (DID) estimates show that in significantly reduces intensity corporate soot emissions, finding holds after a series robustness tests. For every 1-unit rate, industrial exporters’ emission decreases by 2.63%. The mechanism analysis shows decrease...
This paper proposes a centralized MTT method based on state-of-the-art multi-sensor labeled multi-Bernoulli (LMB) filter in underwater multi-static networks with autonomous vehicles (AUVs). The LMB can accurately extract the number of targets and trajectories from measurements affected by noise, missed detections, false alarms port–starboard ambiguity. However, its complexity increases as sensors increases. In addition, due to time-varying environment, AUV detection probabilities are...
Passive sonar is widely used for underwater target tracking which has the advantages of long work distance and excellent concealment, so it a widespread use in military civil fields. In this paper, passive method based on multiple autonomous vehicles (AUV) proposed. utilized to detect locate target, AUV's autonomy good maneuverability are track target. Firstly, with single AUV introduced detail. Then, AUVs proposed including communication mode between AUVs, cooperatively localization method,...
In this paper, an adaptive control scheme with disturbance estimation is proposed for the station keeping and trajectory tracking of underwater vehicle-manipulator system (UVMS) in a task space.

The paper investigates underwater multi-target tracking (MTT) in a multi-static system using autonomous vehicles (AUVs) as receivers separately from transmitters. most critical of MTT is accurately extracting the target trajectories collected measurements, which are generally influenced by clutter, missed detections, and port-starboard ambiguity. Moreover, detection parameters (target probability clutter rate) used methods typically unknown change over time due to varying environmental...
Autonomous underwater vehicles (AUVs) with bearing target tracking capability are fundamental and essential. However, they face the problems of high nonlinearity, difficult trajectory initialization, poor multi-target (MTT) performance. Consequently, we adopt a novel MTT method for multi-AUV based on fast Labeled Multi-Bernoulli (LMB) filter. In this method, LMB filter uses belief propagation (BP) to solve data association problem quickly effectively approximate during update step. And...
