This paper describes a WiFi/BT combo SoC with integrated dual-band PAs, LNAs and T/R switches, supporting concurrent receiving for improved throughput by 30% in dense networking environment of 2.4GHz ISM band and wide-range transmitting capability (>20dB) while keeping good output power accuracy and PA power efficiency. The measured 2.4GHz/5GHz WiFi 54Mbps RX sensitivity is −78.2/−78.1dBm and Pout...
Striving for sustainability has been adopted as a core value and guiding principle for development in the twenty-first century worldwide. Considering the learnings and changes of sustainability in society, especially the connection between software understanding and hardware construction was the key issue for the government. After the Earthquake 921 in 1999, the damages of school buildings started...
Question classification is an essential part of Question Answering system(QA). This paper introduces our research work on automatic question classification that depends on the sample set including questions from legal forum. We propose a taxonomy for law question, and divide questions into three main parts: civil, criminal and administrative according to Chinese legal system. We have experimented...
This paper proposes a multi-task learning algorithm to classify the Chinese legal questions using deep convolutional neural networks (CNN). First, we propose a multi-task Convolutional Neural Network (CNN) for classification of Chinese legal questions with trainable word embedding where coarse grained classification is the main task and fine grained classification is the side task. Second, we develop...
An OVT based on Mach-Zehnder interferometer is proposed in this paper, which helps to convert the electro-optic phase delay into the displacement of the interference fringe. And then, the voltage applied to the electro-optic crystal is obtained by positioning the displacement of the fringe, and the effectiveness of this method is verified by experiments. The new OVT meets the requirements of 0.5%...
This paper addresses the stability results of a Markov jump linear system with parameter uncertainties and time-varying delay. A geometric sequence based method is used for delaypartitioning. Then, a modified geometric sequence division (GSD) dependent augmented Lyapunov-Krasovskii functional (LKF) is constructed with respect to the state variables forming in geometric progression. By employing the...
In order to enhance the tracking performance of maneuvering target by forgetting factor RLS algorithm, an improved forgetting factor adaptive function is proposed based on cosine function. This adaptive function can adjust the forgetting factor dynamically according to the tracking error. In addition, a comprehensive predictor is designed, which dynamically selects the linear predictor or the square...
In this paper, in order to replace a conventional electric linear actuator which is consist of rotary PM machine and ball screw, a novel double-sided five-phase modular linear permanent magnet synchronous machine (MLPMSM) is proposed and designed with the same volume. The basic structure of the machine is firstly described and the major dimensions of one module are then optimized to acquire the largest...
In order to reduce the permanent magnet (PM) volume and combine the advantages of in-wheel motor, a novel modular-stator outer-rotor flux-switching permanent-magnet motor (MSOR-FSPM) whose PM volume is half of that in conventional outer-rotor flux-switching permanent-magnet (COR-FSPM) motor is proposed. However, cogging torque and torque ripple of MSOR-FSPM motor are especially worse due to the inherent...
Reducing greenhouse gas emissions becomes a top priority in the world with the emergence of global warming and environmental problems. Thus, a variety of renewable energy appears during the last decades. The Ocean, which covers two-thirds of the world, captures and stores huge amounts of energy which could satisfy 5 times of world energy demand. During the last 10 years, various Marine Current Energy...
Deep learning has brought a series of breakthroughs in image processing. Specifically, there are significant improvements in the application of food image classification using deep learning techniques. However, very little work has been studied for the classification of food ingredients. Therefore, this paper proposes a new framework, called DeepFood which not only extracts rich and effective features...
On-line detection technology on abrasive particles in lubricating oil liquid is of great significance to evaluate the working or fault state the mechanical equipment, the paper based on the reverse-double-excitation solenoid wearing debris sensor model, the theoretical analysis and finite element simulation of the sensor are carried out, and the results of the two methods are consistent. As the radius...
Modern browsers implement private mode to protect user privacy. However, they do not agree on what protection private mode should provide. We performed the first study on comparing private modes in popular desktop and mobile browsers and found many inconsistencies between different browsers and between the desktop and mobile versions of the same browser. We show that some inconsistencies result from...
This paper presents a physical-aware diagnosis technique for failing dies with multiple interconnect defects, including open and bridging. Our diagnosis technique considers fault masking/reinforcement and Byzantine effects. We use a section, a piece of interconnect, as the physical-aware diagnosis unit. We adopt the Single Location in a Cluster (SLIC) technique, where sections with similar simulation...
Companies leverage plenty of monitoring tools collecting performance metrics of Telecom BSS to assure it is in good status. The influence of the system failure is variance, depending on the length of time to finish the system reparation. The metrics collected by monitoring tools may have the indication of the system failure, and the maintainers have chances to foresee a system failure from those metrics...
This paper introduces test solutions for Integrated Fan Out Wafer Level Chip Scale Packaging (InFO WLCSP) which has the promising of being a very cost effective solution to achieve “More than Moore's law” for mobile devices — more so than 3D integrated circuits (3DIC). InFO WLCSP has its own unique test challenges and it is important to have high-quality screen methodology for severe defects and potential...
Fusing RGB and depth data is compelling in boosting performance for various robotic and computer vision tasks. Typically, the streams of RGB and depth information are merged into a single fusion point in an early or late stage to generate combined features or decisions. The single fusion point also means single fusion path, which is congested and inflexible to fuse all the information from different...
BaTi5O11 thin films with single-layer thicknesses about 400 nm were deposited on the Si substrates by sol-gel method. The influence of surface morphology, optical and dielectric properties was mainly investigated. The diffraction pattern showed that the annealed films exhibited a polycrystalline microstructure, and the increase in grain size of BaTi5O11 thin films occurred with an increase in annealing...
In this paper, a novel 5-phase double-sided C-core modular linear permanent-magnet synchronous machine (MLPMSM) used for the linear steering engine is researched. Firstly, the structure of the MLPMSM is depicted. Then the thrust produced by one module and the total thrust force of the machine are deduced and analyzed. In the ideal condition, all the harmonics in the thrust force can be eliminated...
The authors present a straightforward and effective approach for minimizing insertion loss (IL) of varactor-based frequency-agile microstrip passive circuits, where varactors are employed as elements of variable reversal capacitances to attain reconfigurabiltiy/tunability on circuit characteristics. Technically, the proposed approach mimics the required capacitances using the varactors together with...
