Target Motion Analysis

Bearing-only target motion analysis (BO-TMA) by batch processing remains a challenge due to the lack of information on underwater target maneuvering and the nonlinearity of sensor measurements. Traditional batch estimation for BO-TMA is mainly performed based on deterministic algorithms, and studies performed with heuristic algorithms have recently been reported. However, since the two algorithms have their own advantages and disadvantages, interest in a hybrid method that complements the disadvantages and combines the advantages of the two algorithms is increasing. In this study, we proposed Newton–Raphson particle swarm optimization (NRPSO): a hybrid method that combines the Newton–Raphson method and the particle swarm optimization method, which are representative methods that utilize deterministic and heuristic algorithms, respectively. The BO-TMA performance obtained using the proposed NRPSO was tested by varying the measurement noise and number of measurements for three targets with different maneuvers. The results showed that the advantages of both methods were well combined, which improved the performance.

Abrasive Suspension

Hot cutting is strictly forbidden in coal mines, especially for those with high density of gas. As the only one cold cutting technology, abrasive suspension jet could be used in coal mines to solve the problem of cutting operation under hazardous environments. Based on the technology of abrasive suspension jet, this paper developed a portable cutting machine which is suitable for the dangerous and complex environment in coal mines. Experimental results indicate that the cutting machine could well meet the requirements of cutting operations in coal mines, such as machinery maintenance. Methods for monitoring the quantity of abrasive within the high-pressure tank and the wear of nozzle were also investigated. Safe cutting could be ensured by application of this portable cutting machine. Promotion of the technology would have significant social and economic benefits.

PID (Particle Impact Drilling) is a new drilling technology which has been developing in the near decades. Utilizing steel particles with high speed to impact the rock stratum, this technology could be used in hard terrane. Compared with ordinary drilling technologies, PID has many advantages, such as long service life, high drilling speed, and low duty cycle, etc. During the process of recycling and separating, the steel particles will inevitably encounter a part of loss. In order to keep the sum of steel particle and working efficiency, the loss rules should be intensively studied. Based on experimental studies, this paper mainly works on the screening efficiency under various conditions including volumetric flow rate of drilling fluid, viscosity and steel particle ratio, etc. It was found that the loss rate of steel particle would increase with the increasing volumetric flow rate, viscosity and steel particle ratio. Furthermore, dimensional analysis was employed to analysis the relationship between loss rate and these factors and one empirical formula was proposed.
