Graphical passwords have been proposed as a possible alternative to text-based schemes, but graphical passwords, in storage and communication, require much more storage space than text based passwords, and network transfer delay is also a concern for them. An idea of "graphical structure plus number theory" (GSPNT) for designing new type of passwords is an alternative to typical graphical...
Long Term Evolution (LTE) is a new bearer service for 4G that greatly improves and simplifies wireless access to packet data transfer. The purpose of the LTE is to efficiently accommodate data users which are busty in nature. A key challenge of incorporating voice traffic into networks with efficiency guarantees lies in the difficulty of releasing the available communication resource when the channels...
This paper presents an intelligent selection method for industrial transmission sphere of interferometer. A typical application of interferometer is to inspect a spherical surface. The surface shapes and irregularities of samples can be measured with the coincidence between the center of concave or convex surface and the cat's eye of transmission sphere (TS). However, due to the type, size and radius...
Resistor detection are mostly suffered from compact size and multiple interferences of environment. In this paper, a method for resistor detection was proposed, which combined selective search (SS), convolutional neural networks (CNNs) and support vector machine (SVM). Using improved selective search method to reduce the time of generating candidate regions; taking advantages of independent features...

It is obtained its static characteristic and vibration characteristics by the analysis results and verified the meeting requirements of the stiffness and the...
The complexity of the mechanism brings great difficulty to the calculation of the mechanism motion reliability, and the computer simulation algorithm based on Monte Carlo method needs a great number of simulation. The further-development of LMS Virtual. Lab was carried out, and the least square support vector machine algorithm was used to construct the response surface proxy model. The PSO-GA algorithm...
To solve the complexity and difficulty of tree species selection of wavebreak forest in a certain area effectively, an improved fuzzy optimum selection model (FOSM) using the tree species suitability multi-index system is proposed for wavebreak forest in flood control planning. And a new relative membership degree formula is introduced in the FOSM. Through the improved FOSM, the tree species recommended...
Due to power combine technology using multi-way microstrip divider that have some disadvantage of long transmission path, more intertion loss, sole orientation and occupy large area, this paper design a new broadband radial eight orientation microstrip divider. It use three step division format, dividing 10GHz∼27GHz microwave signal to eight output port. This divider intertion loss is low and transmission...
A novel vibrating ring gyroscope is proposed in this paper, and the structure employs axisymmetric ring resonator and capacitance transducers. Motion characteristics of the ring resonator and the setting of the capacitance electrodes are discussed in detail. The simulation results demonstrate that the natural resonant frequency of the operating mode of the gyroscope is 8.805 kHz and 8.807 kHz, and...
To evaluate the influence of voltage sag on electric-equipment and guide the design of compensation scheme for voltage sag, we need to evaluate the severity of effect of voltage sag on loads. This paper analyses the agglomeration effects of multiple voltage sag on the time scale. For irregular multiple voltage sag, this paper converts its voltage time-series curve into voltage duration curve, and...
To maximize the efficiency of wave attenuation of anti-wave forest with low cost, a multi-objective optimal layout selection model using improved fuzzy entropy was proposed. A new entropy weight calculation formula was introduced in the fuzzy entropy to improve the reliability of entropy weight. The effect of each vegetation factor was quantified and analyzed. The law of wave attenuation was revealed...
Image registration is to find the transformation parameters between images, which is in order to eliminate or reduce the image nonlinear or linear deformation caused by the imaging equipment or imaging conditions. In this paper, an image registration model based on the relationship of geometric projection imaging is established. First of all, proposed a calibration method based on planar pattern,...
The electric vehicle (EV) replacing the traditional fuel vehicle has become an inevitable trend of the development of low carbon economy because of its characteristics of green environmental protection, energy saving and high elïïciency. With the popularization of electric vehicles, random charging of scale electric vehicles in time will increase the influence of uncertain factors in power grid operation,...
Motivated from the idea of "graphical structure plus number theory", two new set-colorings subject to some constraint sets are defined: one is the strong set-coloring (F, F') with the edge set-labelling F' induced by the vertex set-labelling F, and other one is the strongly total set-coloring. We show that every simple, connected (p,q)-graph G admits a strongly total set-labelling, and any...
