A class of nonlinear systems with external disturbances and noise are studied, where the state of the system cannot be measured. A controller is designed by using the estimated state with an observer such that the states of the closed-loop system track the states of a given reference model, and meet a given H performance, at the same time attenuate disturbance and satisfy a guaranteed cost upper bound...
Because of related patents had relaxed and gradually parity of equipment prices, promote related technologies and applications spring up. Hailed by ‘The Economist’ as catalyst of ‘the third industrial revolution’, 3D printing, also known as additive manufacturing, looks set to have a significant impact on manufacturing in the near future, with the steam and electric power technology par. Base on these...
This paper presents a novel integrated multiband vertically polarized antenna based on two half Vivaldi antennas and a slot antenna for V2X communication. It covers multiple frequency bands for vehicular communications, including LTE, WiFi-2.4G, WiFi-5G, Bluetooth, and DSRC bands. The integrated design can reduce mutual coupling among 3 ports and 5 application bands and can be fabricated a single...
Since English is the most important second language, how to help students learn English through appropriate technology is a critical issue in non-English speaking countries. In this work, a digital pen and paper interaction platform (DPPIP) with an attention recognition and review mechanism (ARRM), which is based on brainwave detection, is designed to assist the lesson review of learners while reading...
This paper proposes a varactor-based reflection-type phase shifter that allows for 360o relative phase-shift range and reduced insertion-loss variation over the entire frequency tuning range. In particular, a novel and compact reconfigurable 90o coupler is devised and it is, theoretically, able to achieve perfect return loss and isolation at each tuning state. Thus, when this 3-dB coupler is terminated...
The integration of radar and communication has attracted general interest with its advantage of equipment miniaturizing and high efficiency of spectrum, especially in intelligent transportation systems because of the need for transmitting and detecting simultaneously and the lack of room for various devices. Among various integration schemes, the integrated waveform which realizes transmitting and...
This is a project supported by the Cultural Affairs Bureau, Tainan City Government, which is about to input design resources to an aging, traditional Siraya indigenous village-Soulang Beitouyang. To create new fashion Brand inspired by Siraya Indigenous culture which is the main discussion of this paper. The purpose of the project is to find creative inspiration for future product design themes from...
The joint radar-communication system integrates the function of detection and data transmission to reduce interference and improve the overall spectrum efficiency, as well as to reduce total volume of devices in vehicles, which is widely used in the intelligent transportation systems. Among these joint systems, a MIMO radar based system has significant advantage for multi users with orthogonal waveforms...
The joint radar-communication system is a good way to meet the intelligent transportation systems' need of detecting the cars and barriers around and exchanging information from each other at the same time. Among various schemes, the joint system with integrated waveform attracts general interest because the interference between the radar and communication subsystems will be fundamentally avoided...
This research aims to assess the effectiveness by clinical trial. A total ten patients were asked to use this game for rehabilitation in 24 sessions. The results of this study can be summarized as follows: a comparison of pre- and post-training assessment results revealed that the programs led to the following significant changes: improved Fugl-Meyer Assessment of motor function (increases of 9.30);...
By sharing hardware resources, integrated radarcommunication systems can effectively solve issues of high cost, complicated electromagnetic environment, and inefficient information processing, which the traditional systems with individual radar and communication models suffer from. For integrated radar-communication systems, accurate channel estimation is essential to guarantee the system performance,...
The fabrication and performance of single-mode Cr-doped crystalline core fiber (SMCDCCF) with high-index glass as a cladding employing on-line laser-heated pedestal growth (LHPG) technique are reported. A 3.9-dB gross gain with net gain of 1.9 dB for the SMCDCCF at wavelength of 1400-nm was obtained. The gross and net gains are the highest yet reported for SMCDCCF with high-index glass as a cladding...
Integrated radar and communication system is a new concept that traditionally independent radar and communication functions can be merged into one hardware platform, which can substantially solve problems like high cost, complicated electromagnetic environment and inefficient information processing and so on. However, most papers concentrate on realising the integration function based existing phased...
The dependence of dynamic range and pulsewidth of mode-locked laser (MLL) with different number of graphene saturable absorber is investigated and compared. The results showed that the dynamic range of the MLL decreased and the pulsewidth became shorter as the number of graphene layer increased. This study provides practical conclusion that the lower layer stacking is preferable to use as saturable...
The strategic supply chain network which is a key factor influencing the efficiency of tactical operations in supply chain network, to move products from manufacturer to warehouses, and final to retailers or end customers with satisfying the request quantity while optimize the overall profitability across the supply chain, is critical. Hence, the distribution reliability assessment plays an important...
Radio Frequency Identification technology (RFID) is the key technology to realize the Internet of things. Currently, using RFID to locate objects indoor is a hot topic in the research on the application of RFID. In this paper, we propose an RFID system based on RFID technology and Wi-Fi wireless communication technology. And we design a corresponding handheld device client software to realize a visual...
Saliency detection plays an important role in computer vision. This paper proposes a saliency detection algorithm which is based on multi-cue and multi-scale with cellular automata. The algorithm constructs a background-based map at first and optimizes it with an automatic updating mechanism — single-layer cellular automata. Furthermore, two important visual cues, focusness and objectness, are added...
Triangular mesh model built by existing surface reconstruction methods still have issues such as dislocation, serial hole, stitching and multilateral collinear. The model existing above-mentioned defects cannot generate standard STL file for 3D printing. To solve these problems, this paper propose a topology structure repair method for triangular mesh model, which containing four types detailed solutions...
This paper introduces an approach for slicing thickness adaptively based on cloud point that aims at the problem of a large amount of data, inefficiency and low precision of 3D printing.

Delay compensation for a class of discrete-time nonlinear networked control systems with bounded controls while imposing positivity in closed-loop systems is considered in the paper. Under the state feedback and the output feedback control, compensation for the network induced delays is designed using the Lyapunov stability theory and matrix transformation with nonnegative control and bounded control...
