For mobile device, it has lower performance so that the hole inpainting cannot be completed in real-time. In order to overcome this shortcoming, we propose an image hole inpainting algorithm with improved FMM for mobile devices. The algorithm fills the hole after 3D image warping by DIBR. First, we mark the colour image and the corresponding holes. Then, we preserve the original image foreground edge information by the improved expanded core of traditional FMM. Finally, we implement the algorithm on mobile device. Experimental results show that the improved FMM proposed in this paper is better than the traditional FMM.","PeriodicalId":399731,"journal":{"name":"Int. J. Comput. Sci.

A deterministic compartmental model for Newcastle disease (ND) is developed and analysed using ordinary differential equation theory. The uncertainties of model parameters were therefore examined using Markov Chain Monte Carlo (MCMC) simulations for the data of chicken death cases due to Newcastle disease from five districts in two regions in Tanzania. The parameter distribution was tested using MCMC convergence diagnostics. The graphical diagnostic test for MCMC used include Trace plots or time series plot, two-dimensional parameter plots and autocorrelation function plots. Hence, model parameters were successfully estimated for numerical simulations and the results of simulations were presented.","PeriodicalId":399731,"journal":{"name":"Int. J. Comput. Sci.

The enormous data generated from this billions level market bring us a lots of challenges and opportunities. One interesting question of modelling this data is that can we discover the hidden pattern of users' characteristics from it? Currently, few works have been made to this area. In this article, we try to build a Bayesian probabilistic model to discover the latent user pictures. Especially, we build a user picture model via hierarchical Dirichlet process from the data of one of the biggest market, lending club. The discovered user picture is interpretable and can be evaluated from many perspectives. To demonstrate the usage of user picture, we also proposed a method to predict the loan status. The experimental results show our approach outperformed the comparison methods.","PeriodicalId":399731,"journal":{"name":"Int. J. Comput. Sci.

In this paper, the direct and simple transient solution technique for the state of the system in a single server/processor Markovian queueing model with feedback is presented using the modified Bessel function of the second kind. This technique appears to economise in algebra. The expression for a time-dependent measure of effectiveness such as an expected number of the customers in the system is also derived. We demonstrate how fast the state probabilities tend to their equilibrium limits when it exists. The sensitivity of the state of the system and expected number of the customers in the system has been also analysed and the results are depicted in the tables and graphs.","PeriodicalId":399731,"journal":{"name":"Int.

Digital image correlation (DIC) method was used to determine the mechanical properties, but it took a long time to calculate the uniaxial tensile deformation. In this investigation a DIC optimisation algorithm method based on speeded-up robust features (SURF) and Newton-Raphson (N-R) was conducted on specimens prepared from the scales. First, the SURF algorithm was used to detect the matched points and their coordinate values in the digital images before and after deformation. Then, the initial displacement of the interest point was estimated from the affine transformation fitted to the matched feature points inside the subset area. Last, the zero-mean normalised sum of squared differences (ZNSSD) metric function was optimised by the N-R iterative method, and the optimised displacement value of the interest points would be gained. The numerical translation experiments and simulation results showed that this method improved the search speed and the measurement accuracy effectively. So the deformation of fish scales for axial tension would be calculated by this method.","PeriodicalId":399731,"journal":{"name":"Int. J. Comput. Sci.

The information retrieval process is very complicated today as it depends on many factors like classification of a web query; number of phrases present in the query, number of in-links and out-links to and from the documents, vocabulary, changing nature of the meaning of words. Information retrieval process mainly involves two steps, retrieval of relevant documents for user queries and retrieved documents are sorted using efficient page rank algorithms. Most of the existing systems use static navigation of the web query and ranking. They mainly depend on the number of in links and out links of a web page. In this paper, we proposed dynamic navigation of web query using B-tree to retrieve relevant documents efficiently by reducing nonrelevant documents and resulting documents are sorted by using an improved page rank algorithm.","PeriodicalId":399731,"journal":{"name":"Int.
