Abstract

Until now, many companies have developed lots of the port machinery remote monitoring systems. However, these monitoring systems usual display the operating status of the port machinery by the schematic diagram, Legend and data. The presentation of information is unable to describe the status of the large number of port machinery. In order to solve the problem, a three-dimensional simulation method of the gantry crane based on the WPF is proposed. This paper studies WPF technology and 3D modeling techniques, on this basis, proposes a kind of the gantry crane 3D simulation method based on WPF, establishes a new generation monitoring system based on 3D, immersive and interactive real-time simulation environment. This system could simulate the real-time 3D virtual scene of the gantry crane, and real-time 3D analog display port machinery running posture and operating environment. Experiments show that CPU and memory usage rate is low enough when the system is running. DOI: http://dx.doi.org/10.11591/telkomnika.v11i4.2404

Abstract

A novel compact microstrip lowpass filter (LPF) is proposed in this paper, which consists of the complementary rectangle split ring defected microstrip structure (CRSR-DMS), open stubs, spurline and the dumbbell-shaped defected ground structure (DGS). Due to the unique response of the presented CRSR-DMS, a low passband insertion loss and a sharp transition of the proposed LPF was achieved. Meanwhile, an improved stopband was obtained by properly adjusting the working frequencies of open stubs, a third-order LPF using spurline and dumbbell-shaped DGS. The measured result of the designed LPF shows that attenuation rate reaches 159 dB/GHz and a wide stopband is obtained from 4.07 GHz to more than 15 GHz. DOI: http://dx.doi.org/10.11591/telkomnika.v13i1.6760

Abstract

Duo to the effect of receiving antenna, there is a certain deviation between the transient electromagnetic signal and the observation signal outputted from receiving antenna, leading to large blind areas in the shallow exploration of TEM. In order to improve the distortion of the outputted signal, the algorithm of deconvolution based on incremental wiener filter is proposed to recovery the signal in this paper. The influence of receiving antenna to transient electromagnetic signal is eliminated, and the optimum estimated is obtained after the algorithm is applied to realize the deconvolution of observation signal. Theoretical analysis and experimental results show that: compared with traditional damping matching method, the recovery signal by the algorithm has a better approximation to the theoretical signal, a higher resolution in shallow exploration, and the damping state of antenna has no influence on the recovery signal. It is of importance for improving transient electromagnetic shallow exploration. DOI: http://dx.doi.org/10.11591/telkomnika.v11i9.3249

Abstract

The multisensor information fusion is a key issue for multisensor system. One of its difficulties lies in the switching of the state of sensor clusters. That is, which direction should the sensor information been fused into at a given moment? An algorithm of multisensor information fusion based on rough set and neural network was proposed in this paper. Firstly, the typical clustering distributions of 54 sensors within one day were regarded as sample space. The rough set was used for access of knowledge to make the decision table of the "data - fusion distribution". Next, the redundant properties and samples of information in one month were removed using the method of knowledge reduction of rough set. Then, the neural network was applied for clustering and analyzing to form the distribution rules of multisensor information fusion. Finally, the rough neural fusion algorithm, the neural quotient space fusion algorithm and word computing fusion algorithm are simulated and analyzed. The results show that the model and algorithm proposed in the paper are efficient in classification and rapid in sensor clustering distribution decide. DOI: http://dx.doi.org/10.11591/telkomnika.v10i6.1661

Abstract

The popularity of public transportation has increased as infrastructures have been repaired and other supporting facilities have been added. One of the facilities which can be added in the transportation system is the implementation of Near Field Communication in order to accelerate each transaction in the transportation system. In airports, transaction activities need to be done efficiently, like claiming baggage at the baggage carousel. The speed of transaction to claim the baggage depends on the number of officers, passengers, and the amount of baggage brought by the passengers. In the conventional system, the most effective way of getting the maximum speed of transaction is to have officers as many as the number of passengers, but this is not efficient regarding the use of human resources. The use of Near Field Communication can solve the problem related to the efficiency of resources, safety, and the increasing speed of transaction.
