Psychotherapy is beneficial for mental illness sufferers, but to find proper and affordable professional to conduct therapy is hard. To solve the problem, we propose an interactive virtual agent to build connection with human users. We will evaluate the mental health level affected by the virtual agent.
This paper characterizes and compares Si and SiC power MOSFETs in high temperature conditions. The superior advantages of SiC power device, including conductivity, breakdown voltage, high switching speed and high temperature operating potentials, are discussed based on the semiconductor physics properties, including bandgap energy, critical electric field, saturation velocity and thermal conductivity...
A high-speed SerDes must meet multiple challenges including high-speed operation, intensive equalization technique, low power consumption, small area and robustness. In order to meet new standards, such a OIF CEI-25G-LR, CEI-28G-MR/SR/VSR, IEEE802.3bj and 32G-FC, data-rates are increased to 25 to 28Gb/s, which is more than 75% higher than the previous generation of SerDes. For SerDes applications...
Unified power quality controller has broad prospects in the future applications. Due to the lack of main circuit and parameter design method of Unified power quality controller (UPQC) with large capacity, In this paper, UPQC series (left) parallel (right), which is the most common structure will be taken as an example, static state mathematical model will be analyzed; Based on static state mathematical...
Configuring large power supply in high load density networks and interconnections between power grids will cause enormous short-circuit current. If the short-circuit current rating of equipment in power system is exceeded, the equipment must be replaced, which is a very cost- and/or time-intensive procedure. A fault current limiter offers a choice in such case. First, this paper attempts to give an...
In order to improve the citrus grading accuracy, fractal dimensions which characterize the color and shape features of citrus fruit were analyzed. Samples were from Citrus unshiu Marc.cv.unbergii Nakai. For each sample, images from peduncle, calyx and two opposite sides were collected. These four images were cut, removed backgrounds, and converted from RGB space to HSI one, then by the following methods,...
Considering no very important passengers' emergency, the existing elevator group control strategies all have their own disadvantages. In order to meet the VIP's needs first, a new elevator group control strategy along with the conception of average hall call waiting economy consumption (AHCWEC) are proposed. At the same time, an elevator system model based on passengers classifying is designed. After...
A robust non-reversing starting scheme for the sensorless switched reluctance motors (SRM) is presented. It is implemented by dividing the phase inductance profile into several symmetric regions with a new robust scheme, and comparing the measured phase currents by voltage pulse injection to estimate the region that the initial rotor position locates. The comparison logic is simple, which ensures...
The brassiere-wearing effect is produced by the combined action of body shape and brassiere. The process is so complicated that it is an issue for people to realize what functions the different factors perform in the change of bust appearance. In this research, an artificial neural network model was applied, in which the input neurons contained 11 possible factors including body measurements and brassiere...
A wide locking range injection-locked prescaler based on CMOS ring oscillators in the 0.25-??m CMOS process is described. The prescaler??s free-running frequency is 1.47 GHz, and the locking range covers from 1 GHz to 2.4 GHz with in-phase and quadrature output. The prescaler dissipates 1.9 mA from a 3.3-V power supply.
Urban sustainable development (USD) is connected with the urban spatio-temporal change, it is very important for decision-makers to rapidly look up for the development information data and analyse the harmony development trend. Supported with the component object model of geographic information system (COMGIS), urban environment, economic and social statistical database, and harmony development models,...
The database is the basis of environment management information system, with the spatial data and associated attribute data increasing continually, the realization of the attribute database updated dynamically is taken as the core issue and must be resolved urgently. Adopting the component object model of geographic information system(GIS), such as Map Objects, using the database connection technology,...
A resonance enhancement technology for low-noise amplifier (LNA) design is investigated in this paper. In this proposed architecture, the character of series/parallel LC resonant tank is used for input and output networks. The LNA is operating at 5.2 GHz, which consumes 8 mW from a 0.7 V supply with a voltage gain of 17.9 dB. It shows good IIP3 of +1.8mW and low noise figure of 2.9 dB. The balanced...
