With the aim of getting more accurate and more reliable stock price predicted results, this paper proposes an effective method which is fuzzy rough set and data mining technology. Firstly, stock prices were classified to some groups according to their different time attribute by using fuzzy set and rough set means. Then we calculated truth values of these groups respectively based on the given fuzzy...
Moving objects detection in dynamic scenes is a challenging task in many computer vision applications. Traditional background modeling methods do not work well in these situations since they assume a nearly static background. In this paper, a novel operator named spatial extended center-symmetric local binary pattern (SCS-LBP) for background modeling is proposed. It extracts spatial and temporal information...
We consider the problem of estimating the structural breaks in a long memory FARIMA process. The number m of break points as well as their locations, the order (p, d, q) and the parameters of each regime are assumed to be unknown. To estimate the unknown parameters, we propose two criteria based on the minimum description length (MDL) principle of Rissanen, namely a direct extension of MDL and an...
In this paper, we adopt constrained relaxation for distributed multi-view video coding (DMVC). The novel framework integrates the graph-based segmentation and matching to generate inter-view correlated side information without knowing the camera parameters. Moreover, graph-based representations of multi-view images are incorporated to form more distinctive feature constraints. The sparse data as a...
In order to purify blogical Chinese herbal medicine from wood etractives and hmicellulose at the molecular level, the fresh Chinese-fir cells were extracted in LiOH solution, and were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir cells. The results are as follows: (1) The extraction mass arrived at the maximum value when LiOH concentration is about 17.5%...
In order to overcome the above-mentioned negative effects, the fresh Chinese-fir shavings were extracted in KOH soultion, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when KOH concentration is about 17.5%. The micro/nano particles in Chinese-fir shavings would be...
H.264/AVC is the latest video coding standard from ITU-T. It provides superior and efficient video coding at low bit rates. Flexible macroblocks ordering (FMO) is an error-resilient tool included in H.264/AVC. In this paper, a novel technique for adaptive classification of macroblocks into two slice groups using FMO method is proposed. With our adaptive macroblocks allocation map, simulation results...
An improved Fish-Search algorithm was proposed for airplane route planning of a class of Plane-Missile cooperation. The mathematical description of this class of cooperation was introduced. Comprehensively considered such key factors of the cooperation as inter-visibility, threat, maximum distance and relative orientation, the constraint conditions and evaluation index were constructed. According...
Unequal error protection (UEP), which provides important data with more protection, has been proven to be able to produce better quality in image communication. Previous UEP schemes are mostly proposed for single-image or single-program scenarios. Yet few are developed for multiple programs. Inspired by the MPEG-2 transport stream (TS), in this paper we transform the conventional TS packets to be...
The butterfly valve performance such as the curves of discharge coefficient is essential for predicting the ability of the valve to operate it along with other essential coefficients necessary for making sure the suitable operation. The availability of performance coefficients for incompressible flow is limited, and experimental testing can be cost prohibitive. However, the extrinsic ability of regulate...
An adaptive location management scheme, called as MPA (Mobility Pattern Adaptive) scheme is proposed for the multi-beam GMSS (Geostationary Mobile Satellite System). Compared with the traditional schemes applied in the terrestrial mobile communication systems, a restraining updating strategy will be applied to the low velocity MES (Mobile Earth Station). Additionally, based on the information theory...
