This paper studies operational optimization design in industrial processes with constrained operational conditions when the operational state is transmitted via wireless networks, inducing noise and packet dropout which negatively affect operational optimization performance. Firstly, given a constrained-input process, a PI controller is designed to stabilize the plant without any steady-state error...
This paper presents a data-driven control scheme to iteratively achieve the desired objective criterion with significant improvement of the convergence performance for linear-time-invariant (LTI) single-input-single-output (SISO) systems. The internal iterative behavior between the current parameter and the optimal parameter is firstly analyzed with mathematic expression. And a novel iterative law...
In this paper, we investigate the performance of KinectFusion algorithm for 3D reconstruction using a Kinect sensor. A sensor model is applied to generate depth image to evaluate accuracy of the algorithm. To obtain ground truth of depth image as well as camera pose, we generate depth data based on a CAD model in a simulation program. In the error analysis, deferent types of noise, including depth...
A major challenge for automatic speech recognition (ASR) relates to significant performance reduction in noisy environments. Recent research has shown that auditory features based on Gammatone filters are promising to improve robustness of ASR systems against noise, though the research is far from extensive and generalizability of the new features is unknown. This paper presents our implementation...
We propose and implement a solution for applying an infrared radiation (IR) image sensor to step-on interface (SOI). SOI is a kind of natural human-robot interface what consists of a projector and a laser range scanner (LRG) sensor. And it enables any interactive touch applications on desktop or floor. We attempt to introduce an IR image sensor such as ASUS Xtion to SOI instead of LRG sensor. In this...
The design of loop filter is very important in GNSS receivers. According to design methodology and filter coefficient calculation method, the performance of four filter design methods are analyzed and discussed for frequency response, loop bandwidth and noise equivalent bandwidth. The range of BNT in different methods and deviation of ideal noise equivalent bandwidth are investigated by simulation...
In view of the existing situation of manual measurement of garment dimensions, machine vision has been used widely in automatic measurement of garment dimensions. In this paper, adaptive median filter algorithm is adopted to eliminate the garment image noise; a fast fuzzy edge-detection algorithm is used to detect the edge of garment image; and a new corner-detection algorithm based on Freeman code...
The three-dimensional dynamic method and MIXTURE two-phase model were introduced. The water container was connected to the nozzle chamber to achieve the low effect for missile launching which contains low noise, low temperature, low light and low recoil. The device was compared to the usual launching equipment. The result shows the special water container launching equipment is advantaged to missile...
In view of the fact that DBSCAN clustering algorithm can identify the data with arbitrary shape and one-pass clustering algorithm has the quick and efficient feature, this paper proposes a two-stage hybrid clustering algorithm. DBSCAN is improved to process the data with categorical attributes. By combining one-pass clustering algorithm with DBSCAN clustering algorithm, a two-stage hybrid clustering...
