shocks on China’s gross domestic product, consumer price index, exchange rate, and gross imports and

Celusion.zip - Cell centered (LAPc) and cell edge (LAPe) algorithms were developed to solve the static neutron diffusion
equation in 2D Cartesian geometry using Lagrange interpolation with the progressive polynomial approximation.
Two benchmark problems were used to test the algorithms the two-group TWIGL problem and
a one-group IAEA benchmark problem. The LAP algorithms showed to be more accurate than a finite
difference method (FDM) and for about the same level of accuracy, the LAP numerical methods have
an efficiency advantage because they have to solve for less number of unknowns. The LAP algorithms
showed more sensitivity to the mesh size than what QUANDRY results showed. Even though the FDMs
algorithm, for the calculation of keff, showed systematically to be less accurate than QUANDRY, LAPc,

Net model we derive formulas for this set (SAFE) directly and for its (smaller) minimal elements

subclass only differ by the permutation of their components. The set SORT, which contains only
one representend of each subclass, is an even smaller representation of the safe states. We also
derive estimates for the size of SORT. Finally we investigate, how our results can be translated to

allocation.zip - There are three methods for handling deadlocks in resource allocation systems deadlock
prevention, deadlock avoidance and deadlock detection combined with recovery. Of these three
methods deadlock avoidance is preferable in many cases but seldom used on account of its high
cost. We present a simple modification of a known deadlock avoidance algorithm, the banker s
algorithm, which has a running time O(mn 2) in a system consisting of n processes and m
different types of resources. Our modified algorithm gives an amortized worst case running time of
O(mn) under certain likely conditions and in that way it can be considered a competitive method
for handling deadlocks. At worst, our algorithm is twice as fast as the banker s algorithm,,2015-05-12 19:24:57,下载2次

in a constant switching frequency control for P-DPC. It
simplifies the implementation of P-DPC procedure by selecting
switching states based on the principle of space vector
modulation (SVM). In order to eliminate power errors caused

is investigated through numerical simulations. By leveraging the ability of PSAs to provide phase and amplitude regenerative amplification,
we show significant simultaneous suppression of both phase and amplitude noises of (D)QPSK signals under optimized
conditions. The reduction in the phase noise variance of a noise-corrupted DQPSK signal obtained by one such regenerative amplification
can be as large as 5.5 folds, showing its good potential for distributed optical regeneration of (D)QPSK signals.

Chebyshev.zip - 无边活动轮廓模型(C-V模型)是水平集分割方法中的一种经典模型.传统的无边活动轮廓模型将灰度同质作为区域分割准则,这使其对于仅含两个同质区域且灰度变化不大的图像能够取得很好的分割效果,但对灰度渐变图像分割时,该模型往往无法得到正确结果.本文针对这一问题,通过引入Chebyshev距离构造一种新的相似度,以此来表征演化曲线内外灰度差异,修改了传统无边活动轮廓模型中均值取值的定义,使得演化曲线在图像灰度变化缓慢区域获得较大的驱动力.新模型克服了传统无边活动轮廓模型不能正确分割灰度渐变图像的不足.实验对比及分析表明,新模型能够更准确地分割灰度渐变图像,同时对噪声有一定的鲁棒性.

A-Novel-Strategy.zip - Image steganography technique is widely used to realize the secrecy transmission.
Although its strategies on classical computers have been extensively researched, there
are few studies on such strategies on quantum computers. Therefore, in this paper, a novel,

based on Moir´ e pattern. Algorithms based on the Moir´ e pattern are proposed for binary
image embedding and extraction. Based on the novel enhanced quantum representation of
digital images (NEQR), recursive and progressively layered quantum circuits for embedding
and extraction operations are designed. In the end, experiments are done to verify the
validity and robustness of proposed methods, which confirms that the approach in this paper
is effective in quantum image steganography strategy.,2015-01-22 12:22:31,下载16次
Object-Tracking.zip - Color can provide an efficient visual feature for tracking nonrigid
objects in real-time. However, the color of an object can vary over
time dependent on the illumination, the visual angle and the camera
parameters. To handle these appearance changes a color-based target
model must be adapted during temporally stable image observations.
This paper presents the integration of color distributions into particle
filtering and shows how these distributions can be adapted over time. A
particle filter tracks several hypotheses simultaneously and weights them
according to their similarity to the target model. As similarity measure
between two color distributions the popular Bhattacharyya coefficient is
applied. In order to update the target model to slowly varying image
conditions, frames where the object is occluded or too noisy must be
discarded.,2015-01-22 12:19:53,下载12次
