In this paper, we will discuss the oscillation of solutions of higher-order nonlinear delay dynamic equations on time scales, which have the following form $$S_n^\Delta(t, x)+p(t)f(x(\tau(t)))=0.$$ We will establish some oscillation criteria for these dynamic equations. Our results improve some previously obtained ones.
As data communication rates are increasing, the possibility of EM emission from equipment becomes more significant and the task of EMI suppression becomes more challenging. Traditional approaches in addressing EMI/EMC issues are not very efficient and cost effective since the compliance tests are usually performed after the systems are fully developed, which may be at extremely high risk of adding...
This paper examines the effects of overconfidence on the medium evaluation process of investment project by a process tracing experiment. The results show that: overconfident has no significant effect on the quantity of browsed information and the content of the information that concerned, but affect the time used to browse the information, the extend and the direction were moderated by the investment...
This paper describes the industry's first heterogeneous Stacked Silicon Interconnect (SSI) FPGA family (3D integration). Each device is housed in a low-temperature co-fired ceramic (LTCC) package for optimal signal integrity. Inside the package, a heterogeneous IC stack delivers up to 2.78Tb/s transceiver bandwidth. The resulting bandwidth is approximately three times that achievable in a monolithic...

As for the graphical modeling software of current domestic power system, it used mostly to be the stand-alone edition or based on C/S (client-server) mode. Compared with the B/S (browser/server) mode, there are some shortcomings in software installation, upgrade and maintenance. This paper aims at developing the graphical modeling software of power system, which is based on the B/S mode, making most...
The integrated crosstalk noise (ICN) has been proposed in the IEEE 802.3ba standard to measure the crosstalk in the high-speed channel and accepted as a replacement of the ICR (Insertion Crosstalk Ratio) for channel noise estimation. As the PHY options of NRZ, PAM-4 and/or Duobinary are actively explored for higher data rate, a generalized ICN model will be needed for characterizing the channel SI...
Data center networks typically have many paths connecting each host pair to achieve high bisection bandwidth for arbitrary communication patterns. Fully utilizing the bisection bandwidth may require flows between the same source and destination pair to take different paths. However, existing routing protocols have little support for load-sensitive adaptive routing. We propose DARD, a Distributed Adaptive...
We design a system of multiplex data acquisition, this acquisition system required not only to be run in high precision magnitude, but also to be capable of restraining power frequency interference for the case of complex application environment complex. In this paper, the advanced high-precision Σ-ΔA/D converter was introduced to be the front end of the 24bits data acquisition system and the π-type...
This paper presents a comprehensive study on the wire bond life for Insulated Gate Bipolar Transistors (IGBT). The main elements are as follows: 1) Substantial non-uniformity in temperature distribution across the chip area was revealed; 2) Additional electrical resistance at the wire bonds was discovered, which can elevate the local temperature and shorten the wire bond life; 3) Thermo-structural...
It is more prone to occur traffic accidents on freeway at night than during the day. The paper adopts field test and takes Changsong freeway as test object, and carries out identification distance experiment both day and night according to horizontal radius and longitudinal slope difference. Through experimental analysis, it is proved that driver's nighttime identification distance is less than daytime...
In order to establish reasonable speed limit standard on freeway at night, it is necessary to study driver's characteristic of speed perception under different driving circumstance at night. Data of driver's perception speed at daytime and nighttime were analyzed comparatively. The impacts of actual driving speed, horizontal curve radius and longitudinal slope on driver's perception speed were analyzed...
When the transient electromagnetic (TEM) method is used in prospecting, primary excitation in a transient system can have any shape. This paper obtains the response of these waveforms by the time-domain approach, which approximates the energizing pulse as a superposition of step functions. We also used a new hankel transform filters made by F.N Kong to calculate the response of step waveform for in-loop...
The demand for broadband access has grown steadily as users experience the convenience of high-speed response combined with "always-on" connectivity. In this paper, we propose a radio over fiber (RoF) based broadband wireless access network architecture. Characteristics of the architecture, advantages and benefits, and appLications of RoF technology are discussed. Moreover, a radio over...

In this paper, the structure characteristic of wind turbine gearbox is analyzed and the principle of defection modulation of gearbox vibration signals is studied. The method of cepstrum and Hilbert...
Electrocatalytic oxidation of indomethacin on a modified multiplewalled carbon nanotubes (MWCNTs) cathode in aqueous solution was studied in this paper. The experiments were carried out to explore the effects of initial concentration, electrolytic voltage, pH, concentration of electrolyte and electrolysis time on removal rate of indomethacin. The results of show that the removal rate reached 78% by...
The important indicator to measure an city's urban centrality is the radiation of it. This study establish an evaluation index system, calculate the extent of radiation of Yulin and the cities around it in the border area of Shaanxi-Gansu-Ningxia-Inner Mongolia and Shanxi province, use Voronoi diagram to determine the scope of Yulin city. The part of the north and the south administrative regions...
Vehicular powertrain test bench was designed. A LabVIEW based measurement and control system for the test bench was secondary developed. CAN signals of powertrain's master controllers, serial signals of electric driving system based on USS and MODBUS protocol were synchronously sampled and monitored. The system integrated various communication protocols in one platform and had a good portability and...
Using the Statistics Package for Social Science (SPSS) as compute tool, this paper sets regression models between population and General Domestics Products (GDP) and analyzes the corresponding development status among population, employment and economy from 1986 to 2006 in Xi'an City. Through correlation and regression analysis, it is concluded that the increasing population in the first and the third...
Contourlet transform has better performance in directional information representation than wavelet transform and has been studied by many researchers in retrieval systems and has been shown that it is superior to wavelet ones at retrieval rate.
