This study mainly analyzed the parameters such as ascending branch slope (A_slope), dicrotic notch height (Hn), diastolic area (Ad) and systolic area (As) diastolic blood pressure (DBP), systolic blood pressure (SBP), pulse pressure (PP), subendocardial viability ratio (SEVR), waveform parameter (k), stroke volume (SV), cardiac output (CO) and peripheral resistance (RS) of central pulse wave invasively...
Protein sequence classification is increasingly crucial in the current “biological information sciences” epoch, where researchers hammer at functional genomics and proteomics technologies for predicting the function of large-scale new proteins. This has sparked interest in the methods which do not rely on traditional sequence alignment, but prefer machine learning approaches. In this paper, we present...
In this paper, we consider a two-echelon supply chain that consists of a retailer and a manufacture. The amount of carbon emitted by the whole supply chain is constrained to a certain cap. Based on standard economic order quantity(EOQ) model, the retailer decides the order quantity and the manufacture decides the production lot size, and their objectives are to minimize their cost subject to the carbon-constraint...
Total Knee Replacement (TKR) is an increasingly common surgery worldwide. A significant contributor to TKR success is post-surgical rehabilitation. In this work, we present Fun-Knee™, a novel sensor-equipped knee support complemented by mobile device-supported games, specifically designed for “gamified” TKR rehabilitation. Two inclinometers are used to measure the knee angle, which is used as the...
A two-dimensional(2-D) analytical model for substrate effect of lateral power devices is developed. By solving the 2-D Poisson's equation, an analytical model is proposed and verified by the agreements between the analytical results and numerical simulation results using MEDICI. It suggests that the optimized substrate voltage modules the distributions of the surface potential and electrical field,...
In this paper, the impact of three dimensional effect of multi-finger layout on Variation of Lateral Doping (VLD), the Variation of Lateral Thickness (VLT) and Reduced Surface Field (RESURF) LDMOS is explored. These devices are compared on the basis of breakdown voltage and on-state resistance. The simulation indicates that compared with VLT and conventional RESURF LDMOS, the breakdown voltage of...
Color brings extra data capacity for QR codes, but it also brings tremendous challenges to the decoding because of color interference and illumination variation, especially for high-density QR codes. In this paper, we put forth a framework for high-capacity QR codes, HiQ, which optimizes the decoding algorithm for high-density QR codes to achieve robust and fast decoding on mobile devices, and adopts...
IBIS-L ground based SAR is able to provide accurate and long-term measurements over relative large areas by combining of stepped frequency continuous wave, synthetic aperture radar and interferometric technique. To measure displacements of an open pit slope in Beizhan iron mine, a novel environmental correction method is presented to perform the atmospheric distortion correction of GB-InSAR. GB-InSAR...
Tremendous underground exploitation as subway tunneling, functional facilities excavation in inner-city environments caused potential damages to buildings and bridges over the construction zone. PSInSAR technique and high resolution SAR data provides a powerful tool for slightly surface deformation in recent years. Till now, it is time to use PSInSAR as an operational and mature technique for geodesy...
Using RADARSAT-2 satellite images from January 2012 to October 2015, this paper employ the PSInSAR(Permanent Scatterer InSAR) technique to acquire coastal lowland subsidence in Zhejiang province. In the Hangzhou Bay Region, the widely distributed silt deposition leads to the entire ground sinking slowly, with 10∼20mm/a in rate. Conversely, the ground subsidence distribution of the Eastern Coastal...
To improve the steering precision and angular resolution of liquid crystal optical phased array, in this paper, we proposed a modified periodic phase controlled method to realize a continuous scanning with a constant angular resolution of less than 20 μrad, meanwhile, its precision is less than 5 μrad (RMS). Also, another method we proposed is called sub-aperture coherence can realize even better...
This paper proposes a novel high-voltage LDMOS with Folded Drift Region (FDR) structure. The structure extends the effective length of the current path in the limited drift region length, and uniformthe electric field profile in order to have a high breakdown voltage. The structure parameters are optimized and the characteristics are investigated by a 2D device simulator MEDICI. The simulation results...
Environmental stress screening (ESS) is a process to eliminate defects caused by materials and manufacturing variations in electronic products by a 100% screening, with the goal to eventually improve manufacturing processes that cause the defects. MIL-HDBK 344A- Environmental Stress Screening (ESS) of Electronic Equipment describes a quantitative approach for planning, monitoring, and controlling...
As a multi-user shared space information transmission asset, the Tracking and Data Relay Satellite System (TDRSS) is critical in establishing an efficient resource scheduling mode, in order to maximize the utilization of system resource and bring the service efficiency into full play. The thesis takes the U.S. Tracking and Data Relay Satellite (TDRS) System architecture as an example, bring forward...
This paper discusses the relation between dorm arrangement and student performance. One of the unsupervised learning algorithms, k-means algorithm, is mainly used in the process of analysis. Students are clustered into several clusters according to their similarity of performance scores. This paper analyzes the result of clustering by comparing it with actual dorm arrangement. In the end, drawbacks...
Electrically powered wheelchair controllers are crucial to the reactiveness of wheelchairs, but most of current controllers failed to deliver their proper functions due to unreliable data processing and open-loop controller. In the present study, we designed a new controller which uses a double CPU mode with two STM32 chips. The first CPU is responsible for collecting and processing the signals of...
All printed documents/credentials are potentially subject to counterfeiting and forgery. Conventional counterfeiting solutions such as watermarking or printing using special-quality paper are not cost-effective. Certification via authorized chops/stamps is low-cost but only provides a false sense of security/ authenticity. To tackle this problem, we propose AuthPaper: a cost-effective, secure solution...
≥10°C Accumulated temperature, Solar radiation, Photosynthetically active radiation, and Light and temperature production potential of spring maize were calculated using 30 years the average daily observation data from 1981–2010, using 582 weather stations showing spring maize and basing on solar radiation equation and AEZ model. Spatial analysis was carried out on the site results in the ArcGIS platform,...
Computer aided programming techniques do not only lead to breakthrough in data management, but also changes the method in realizing sustainability in smart homes. Smart technologies improve the solar energy collection and reduce water wastage in fire protection system tests. It helps us achieve the goal of win-win-win environment, social and economics, i.e. sustainable development in our society.
As the revolution of power market, the condition of energy and environment has become serious. It is an urgent problem on how to built a reasonable model of reserve markets. This paper describe the reserves market briefly, and then construct the model of co-optimization of energy and reserves as implemented in reserve markets. In this mode, it is discussed the reserves of generators in the condition...
