The probability of a conventional event that consists of a static verb such as be, stay, remain and its contexts can be easily found. However, to derive the probability of a verb event stated by a non-static verb is not as simple as conventional events. In the paper, we introduce a type of evolving function called observation function and address a measure to attain the probability of the verb event...
In this paper, a new basis for polynomial curve modeling is presented with its linear computation. This new proposed curve can be formed by the convex combination of its blending functions and related control points. Moreover, several important geometric properties for this curve are identified, for examples, a partition of unity, convex hull property and symmetry. Later the recursive algorithm, coefficient...
A class of quasi-Hermite base function is established in space Gamma = {1, t, sin t, cos t, cos 2t}. The corresponding quasi-Hermite curves with a shape parameter alpha are defined by the introduced base function. The curves can easily be adjusted by using the shape parameter alpha. With the parameter chosen properly, the defined curves can precisely be used to represent straight line segment, circular...
Aiming at the positioning problem of Ad-Hoc networks of sensors node location, a beacon selected localization algorithm (BSLA) is proposed in this paper. The proposed method considers sufficiently both the topology relationship among beacons and the topology relationship between beacon nodes and unknown nodes. We introduce the concept of collinearity and apply it into the localization of the multihop...
We show that the syntactically rich notion of inductive families can be reduced to a core type theory with a fixed number of type constructors exploiting the novel notion of indexed containers. Indexed containers generalize simple containers, capturing strictly positive families instead of just strictly positive types, without having to extend the core type theory. Other applications of indexed containers...
Material shape of car dumper during dumping is analyzed. The weight and rotary inertia of material are changed with the tipping angle during dumping. Material moment and rotary inertia on-line calculation thought is put forward. Object position measuring technology is applied to determine initial parameters and the graph display of whole dumping process is realized by coordinate conversion. The variety...
Multi-resolution expression is the import characteristic of discrete global grid. The geometrical distortion in multi-resolution expression can decide the ability of multi-scale transformation of discrete global grid. It is also the influencing factor of stability of discrete global grid. The source of geometrical distortion in multi-resolution expression was analyzed in this article. The method of...
Different from the conventional communication method between users and machines, we use hand gesture to control the equipments. This paper presents hand gesture recognition applied human-computer interaction (HCI) system. It presents new method to automatic gesture area segmentation and orientation normalization of the gesture. It is not mandatory for the user to keep upright gestures in the regular...
As electrical distribution networks become more active, it is important to identify the conditions in which traditional measures of network performance still provide accurate representations of network behaviour. This work describes the development of algebraic relationships an aggregated network model, expressions for the risk to which the system is exposed under different operating periods are developed...
The ldquoGE Curverdquo has been in use for many years by most utilities as their sole criteria for determining the serviceability of connected loads to their electrical system. This long term usage has bred familiarity with both the method and the criteria. In recent years, the IEEE Voltage Flicker TF undertook the task of adopting the IEC method of determining flicker. This was done so as to bring...
As to these bearings, whose outside diameter is large (d ges 120), price is high, and life is long, the number of samples chosen is small in order to save sample quantity and test cost, not according to the standard. There are a lot of users to choose the bearings less than 8 pcs to test the life for comparing the different bearings quality. According to the trait of rolling bearing submitting to...
This research effort attempts to investigate the conditions under which better variance reduction can be achieved in simulation of a system where random deviates are generated by the acceptance-rejection technique. To induce correlation among the generated deviates, both antithetic and stratified sampling will be considered to study the magnitude of variance reduction in estimating the renewal function...
Two kinds of polynomial bases with parameter are constructed in this paper. Based on these bases, two kinds of curves with shape parameter are defined. The first kind of curve contained the Wang-Ball and Said-Ball curve of ninth degree and many curves located between them. The second kind of curve contained the Said-Ball and Bezier curve of ninth degree and many curves located between them. By analyzing...
We present a new simple form window function with application to FIR filter design, which has superior performance compared to the several commonly used windows. The new window is almost equi-ripple. For sufficiently high orders, the proposed window has the main lobe width of roughly equal to that of the commonly used Hamming window, while featuring 5.6 ~ 12 dB smaller side lobe peak. For lower window...
Image Segmentation is one of important tasks in conventional or document image processing. Tsallis-entropy based image thresholding method has been considered one of the most efficient ways for image segmentation. At present one useful way in entropy-thresholding segmentation is based 2D vertical segmentation, but obvious limitations exist in this approach. In this paper, a method 2D obique segmentation...
Four kinds of trigonometric spline curves with shape parameter are presented in this paper. The trigonometric spline curves are constructed with three consecutive control points for each curve segment. The given curves posses many properties of the quadratic B-spline. Meanwhile, they have many better properties than the quadratic B-spline curve. The given curves have continuity with equidistant knot...
In order to improve the brightness of gas field ion source (GFIS), numerical simulations of field distribution around the tip apex and the shank were performed taking into account an increase of gas capture area for field ionization. This experiment results of ion current at gas temperature 300K and the calculation results at same condition are compared to confirm the reliability of the calculations...
Complex networks can be classified in three main types: random networks, small-world networks and scale-free networks. In this work we studied the cycles distribution of these three types of networks and then we proposed one universal Gaussian function that mathematically models the distribution of the three classes. The proposed equation can be used to model any network including social networks.
Many techniques have been developed for traffic sign recognition, but it seems related systems have hardly been applied in real vehicles. One reason is that a visible-light camera can not give competent performance in adverse conditions. In the paper, we discuss how to make the best use of a visible-light camera for over-exposure and under-exposure conditions. Two approaches are developed to enhance...
Few studies were mentioned to illustrate the role of plant hormones-IAA and ethylene in split-pit formation. Here, a random sample of 100 developing fruits from 7-year-old early maturing nectarines (Prunus persica L. Batsch cv. Ruiguang 5) was used as test material. The shape index and growth index of the sampled nectarines was comparatively analyzed to show the relation between fruit un-uniform growth...
