Motivated by great performance gained by Recurrent neural network applied on machine translation, people began to pay attention to image describing with related deep learning methods. Recurrent neural network can not remember long term information but Long-Short Term Memory(LSTM) can handle this well. However, the LSTM applied on image describing to predict sentences in previous literature [1] can...
This paper presents a time domain model of the non-contact surface wave (SW) ultrasonic scanner. Computations are divided into three steps: wave propagation from air-coupled emitter to the inspected sample (step 1), SW propagation along the inspected sample surface (step 2), leaky wave re-propagation from sample to air-coupled receiver (step 3). Each step is computed based on Rayleigh's integral employing...
With drastic device shrinking, low operating voltages, increasing complexities, and high speed operations, radiation-induced soft errors have posed an ever increasing reliability challenge to both combinational and sequential circuits in advanced CMOS technologies. Therefore, it is imperative to devise efficient soft error rate (SER) estimation methods, in order to evaluate the soft error vulnerabilities...
Virtual reality is a research direction with rapid development, has important significance for national defense and engineering practice. The wave modeling is an important topic in the research of virtual reality. And it is applied to the naval ships manufacture, the naval gun firing experiment, and Marine virtual training, etc. It laid the virtual exercise, warships and submarines test basis. From...
In this paper, we generalize the Gaussian Mixture Model (GMM) in two ways: a) by introducing novel distance measures between two vectors based on nonlinear maps to give more general mixture models; b) by building mixture models based on multiple different kinds of distributions. These two generalizations cope with different problems arisen in feature modeling. Mixture model obtained by first method...
The high-precision positioning of obvious target for the image edge, we usually use line diffusion function model, when we generally use normal function, in this paper, we use simple arc tangent function instead of normal function for positioning the image edge, the mathematical model of this method is simple and has fast calculation. getting the gray value of the phase as observations for adjustment...
Peer-to-Peer (P2P) networking is beneficial when removing a centralized server. On the other hand, new mechanisms are required to compensate for the central authority, especially for network security and dependability. In this paper, we propose a new fuzzy reputation (Fuzzy-Rep) model to improve security and dependability of P2P e-commerce. The model employs fuzzy logic inference rules to assess transactions...
Multi-thread is a mature and widely-used programming mode for multitasking applications developing, especially in Java. However java.lang.Thread is not designed for HPC parallel programming. Java multi-thread program is confined within single compute host. CommonJ Work Manager is a joint specification proposed by IBM and BEA. Work Manager is a higher-level alternative to using Java Thread. Originally,...
