Among various parameters impacting on the performance of UV camera for daytime corona inspection, the solar-irradiated leakage (SIL) is the most influential one according to the BLUP theory. The minimum detectable corona is limited by equation. In this paper, a series of UV filters are used to represent different SIL levels on a clear day. After a UV filter with a transmittance of 10−13 above 300...
This research aims to identify how the Chinese and Macanese students would perform if they were treated in the student-centered approach, moreover, the researchers specify the assessment method which requires them to perform an in-depth understanding of the course material. As a result, the researchers were amazed by the students, and this interventional group of student proves the stereotype of Chinese...
This paper presents a simple method to design miniature wideband band-pass filters. In order to verify this method, we designed a miniature microstrip wideband band-pass filter by using open-loop resonators. Eventually we achieved a 10th-order miniature wideband band-pass filter with center frequency 2 GHz, bandwidth 1 GHz and the relative bandwidth 50%, passband insertion loss less than 7.3 dB, stop-band...
In today's scaled out systems, co-scheduling data analytics work with high priority user workloads is common as it utilizes better the vast hardware availability. User workloads are dominated by periodic patterns, with alternating periods of high and low utilization, creating promising conditions to schedule data analytics work during low activity periods. To this end, we show the effectiveness of...
In this paper, we proposed a general analytical model for mobile relay scenario using stochastic geometry approach. By applying different parameters into this general model, the Cumulative Distribution Function of the SINR and the average achievable rate on different links in both traditional mode and relay mode can be obtained. According to numerical results, we observed that penetration loss between...
Depth-Image-Based Rendering (DIBR) is a technique which utilizes 2D texture images and corresponding depth maps to synthesize stereoscopic views. However, it could introduce the hole artifacts that heavily degrades the rendered quality of 3D video. In this paper, a content-adaptive Depth-Video-Based Rendering (DVBR) method is proposed to eliminate the hole artifacts that are caused by quantization...
In this paper, we report one enhanced NMOSFET photodetector fabricated using standard triple well process. The NMOSFET transistor is placed in the deep nwell (DNW). During the photodetection, the gate is connected with the bulk of NMOSFET and left floating so that the potential of both the bulk and the gate can be modulated by illumination. It's found that the optical current can be dramatically increased...
The source parasitic capacitor significantly influences the terahertz responsivity for CMOS terahertz detector. In this paper, the gate-enclosed MOSFET is used for terahertz signal detection in order to reduce the source parasitic capacitor. 3D-TCAD simulation reveals that the gate-enclosed structure improves the voltage responsivity (Rv) of the THz detectors and reduces noise-equivalent power (NEP)...
Traditional deterministic methods usually applied to the most severe and low probability events in power system risk assessment, computation results are therefore much conservative accordingly. Considering both probability and their impact of the effects, risk assessment methods can provide comprehensive effect on the whole power system. The status quo related to risk assessment is reviewed. The meaning...
This paper presents a novel method to improve the stereopsis and visual comfort of 3D images based on an idea that apply the stereoacuity prior to the process of synthesizing a virtual view by DIBR (Depth image based rendering) technique. DIBR technique is widely used in 3D film and TV programs. However, an emphatic issue is that the stereo video has a weak stereo-effect and viewing discomfort since...
Modern processors are often constrained by a given power budget that forces designers to consider different trade-offs, e.g., to choose between either many slow, power-efficient cores, or fewer faster, power-hungry cores, or to select a combination of them. In this work, we design and evaluate a new Hadoop scheduler, called DyScale, that exploits capabilities offered by heterogeneous cores within...
To offer diverse computing capabilities, the emergent modern system on a chip (SoC) might include heterogeneous multi-core processors. The current SoC design is often constrained by a given power budget that forces designers to consider different decision trade-offs, e.g., to choose between many slow cores, fewer faster cores, or to select a combination of them. In this work, we design a new Hadoop...
It is more intuitive and clear to analyze and judge the pipeline accident with completely inversion and prediction. This paper studies accidents inversion and analysis methods for the oil and gas pipeline SCADA system. First, we save log data and real-time data section in the database and creating event scenes. Then, we use inversion with the accident realtime data section, log data and the timeline...
This paper mainly proposes a least square fitting method to obtain variable bandwidth FIR filters with fixed length. The proposed method fits every corresponding tap of fixed filters with the same length and sampling rate but different bandwidth. The bandwidth is the variable of the fitting polynomials in this method, which makes it easier to get filters with needed bandwidth online than traditional...
As to the uncertainty relations between soil organic matter content and spectral characteristics, at first, based on the objective function that the sum of squares of generalized weighted grey distance is minimum, this paper proposes a new self-iteration grey clustering model whose classification standard is unknown. It then establishes a grey clustering estimating model of soil organic matter content...
A method for accurate fault location on a distribution line with branches using the C-type of traveling wave signal and PNN is presented. The aim is to combine different location methods to improve the accuracy of fault location. In this method, the first step is determining the fault distance by C-type of traveling wave location method, then because branches which have the same distance to the busbar...
It is common nowadays to architect and design scaled-out systems with off-the-shelf computing components operated and managed by off-the-shelf open-source tools. While web services represent the critical set of services offered at scale, big data analytics is emerging as a preferred service to be colocated with cloud web services at a lower priority raising the need for off-the-shelf priority scheduling...
This paper presents a two channel interleaved 6-bit 2GS/s successive approximation (SA) analog-to-digital converter design. The proposed SAR-ADC employs different comparators for each stage, which eliminates digital control delay as in con- ventional design. Using small size of capacitor and pre ampli- fied comparator, the sampling rate limitation has been broken up with which is only related to intrinsic...
Nitride Read Only Memory (NROM) device is difficult to achieve eight-level cell operation using the conventional channel hot electron injection programming method due to low reliability. In this work, a high density eight-level cell programming method is proposed in a 90 nm NROM device. This new method first uses a double-side band-to-band tunneling hot hole injection (BBHHI) mechanism for a uniform...
We investigate the junction leakage current and device performance for 45nm SiGe/Si pMOSFETs using various silicide technology. It is found that with the conventional Ni silicide method, the leakage current of a SiGe/Si junction is large and attributed to band-to-band tunneling and the generation-recombination process. The two leakage contributors can be suppressed quite effectively when a Si cap...
