Description: 本模型研究了在恒定频率下驱动的二维声悬浮器，几何结构作了一定程度的简化，弹性小颗粒在驻声场中均匀释放，确定了这些颗粒在声辐射力、黏性阻力以及重力影响下的路径。(In this model, a two-dimensional acoustic levitator driven at a constant frequency is studied. The geometric structure is simplified to a certain extent. Small elastic particles are uniformly released in the standing sound field. The path of these particles under the influence of acoustic radiation force, viscous resistance and gravity is determined.)

Description: Java implementation for DBSCANSD, a trajectory clustering algorithm.
DBSCANSD (Density-Based Spatial Clustering of Applicationswith Noise considering Speed and Direction)[1] is a clustering algorithm extended from DBSCAN [2]. It can consider speed and direction, which is essential for maritime lanes extraction. The output of this algorithm is a set of Gravity Vectors (GV) and Sampled Stopping Points (SSP).
In the present version, the implementation has not included generating SSP yet, but I shall add this part later.
Since the AIS data provided for this project is confidential, I cannot upload it to github as example. But I generated a toy data set and put it in the src folder which can be tested with the program. And it will be great if you use this algorithm for other domains' problems, such as tracking data of vehicles, pedestrian, hurricane or animals.
More details about this algorithm can be found in [1]. The link is as following:

Description: # How To Run The Code ?
After downloading it to local,
1. cd to the folder of src/boliu/dbscansd/
2. compile all the .java files using:
javac *.java
3. cd to the folder of src/
4. execute the program using the following either command:
java boliu.dbscansd.Main inputfile outputfile lineNum eps minPts maxSpd maxDir isStop
* @param inputfile the input file path
* @param outputfile the output file path
* @param lineNum the designated number of trajectory points for clustering (if the size of the input file is less than lineNum, it will extract all the points)
* @param eps 1st parameter of DBSCANSD, the radius
* @param minPts 2nd parameter of DBSCANSD, the minimum number of points
* @param maxSpd 3rd parameter of DBSCANSD, the maximum SOG difference
* @param maxDir 4th parameter of DBSCANSD, the maximum COG difference
* @param isStop boolean value (0/1), if you would like to cluster stopping points (1) or moving points (0)
--e.g. java boliu.dbscansd.Main toy_data.csv output 70000 0.03 50 2 2.5 0
In this way, the program will do the job on toy_data.csv file.
It will extract the first 70,000 moving points from the data and then run DBSCANSD on the dataset.
The final output will be two files:
output_gv.csv (gravity vectors)
output_movingclusters.csv (original clustering results with more rows).
5. waiting for the result :) The running time will vary with different sizes of the input data and other input parameters.
6. Star it if it helps \*-\*

Description: We model deformation in the subduction channel (SC) and overriding plate as two-dimensional incompressible, Newtonian, isotropic, Stokes viscoelastic creeping flow under the influence of gravity in a Lagrangian finite element grid. SC flow in the trench-parallel direction is assumed to be small compared to flow along a plane normal to the trench axis.
