For more than three decades, Box and Jenkins' Auto-Regressive Integrated Moving Average (ARIMA) technique has been one of the most widely used linear models in time series forecasting. However, it is well documented that many software failure observations are nonlinear and ARIMA is a general univariate model developed based on the assumption that the time series data being predicted are linear. Therefore,...
Weblog and some new social media are cause of an evolution in World Wide Web. Weblogs are web pages with several dated entries usually arranged in reverse chronological order[1]. This form of online diary media has become an influential web application, with thousands of blogs added on the web every day. In general, blog sites cover a wide range of topics. Sites with topics referred to politics or...
In 1991, with the emergency of the digital printing, printing industry has come to a new era. Experiencing over 20 years' development, digital printing has shared a very large market with its advantages. It has advantages on demand, excellent color accuracy, Low cost of proofing, quicker printing period and other strengths. This article will have a intensive research on the development trend of digital...
In this paper, a novel image enhancement method is presented. Firstly, an image filter based on Particle Swarm Optimization is adopted to eliminate noise. And then, image enhancement by Particle Swarm Optimization and DWT is presented to improve image quality. Experimental results demonstrate that this method outperforms the existing well-known methods.
In this paper, a kind of gray image digital watermarking algorithm is put forward. And this algorithm is to use the technology of combining discrete wavelet transform and discrete cosine transform with singular value decomposition based on chaos, and scrambling for the purpose of raising security, invisibility and robustness of watermark. It hided the digital watermarking in the discrete cosine transform...
In this paper, we first conduct a detailed analysis of special equipment safety, and then on this basis, we propose countermeasures: develop and implement the safety production responsibility system, the periodic inspection system, uphold the system of certificates, correct use, careful maintenance. Finally, we use “electricity loss protection system of elevator” as an example to explain.
IPv6, as the protocol of future generation, has many advantages in constructing home information network. This paper proposes construction of a kind of home information network based on IPv6 protocol and discusses prototype design. This construction has expansibility and practicability with simple operation, and collocation and many advantages in constructing IPv6 home information network.
Contourlet is a new geometric multiscale tool that is based on multiscale filters and directional filter banks. It not only inherits the multiscale characteristics of dimensionality-inseparable wavelets, but also has the flexible multi-directional characteristic by changing the directions of transform and sequences. In this paper, we developed a new non-subsampled contourlet transform (NSCT) and gray...
We are dealing with a matrix of the size 136 (formerly 79) known as financial social accounting matrix (FSAM). Inside a financial SAM is a square matrix of 107 rows times 107 columns sub set known as SAM. We are augmenting a command line based software for more functionality. The addition from us includes: data base for the output, bar chart output, table generation, graphical presentation of path...
In this paper, we will determine the shape of a snowboard course (currently known as a “half pipe”) to maximize the production of “vertical air” by a skilled snowboarder. "Vertical air" is the maximum vertical distance above the edge of the half pipe. For designing the ideal shape of the half-pipe, we want to use the method calculus of variations to determine the function of the shape of...
To objectively reflect the service quality of each building materials logistics provider, and based on the analysis of the development tendency of operation management of building materials logistics, Fuzzy TOPSIS method is introduced in this paper to establish an evaluation index system of the logistics provider and determine the weight of each evaluation index, which provides an effective decision...
While biometric fusion is a well-studied problem, most of fusion schemes cannot account for missing data (incomplete score lists), that is commonly encountered in large-scale multibiometric identification systems. In this paper, we present a new approach, where the RIBG (Robust Imputation Based on Group method of data handling) is used for handling the missing data. Since this scheme can be followed...
Dr. Soetomo General Hospital already has a Hospital Information System which has been computerized for data storage of each recapitulated patient's disease. Since data recapitulated the patient's disease is increasing, Dr. Soetomo Hospital needed an application which can provide information for decision makers. One application that can help in decision making is data mining. Data mining with hybrid-dimension...
Based on grey GM(1, 1) of the forecast for engine wear trend, the Markov chains is presented, so the grey GM(1, 1) and Markov chain model for predicting the engine wear trend is built in this paper. The model is felled together two kind of inherent quality of time list data organically since evolvement rules is mined from time list data and random response is attained through state transfer probability...
Market-Basket Analysis is a process to analyze the habits of buyers to find the relationship between different items in their market basket. The discovery of these relationships can help the merchant to develop a sales strategy by considering the items frequently purchased together by customers. In this research, the data mining with market basket analysis method is implemented, where it can analyze...
The various components of parametric and non-parametric cost estimation methods assume that the historic data used in cost analysis are true representation of the relation between the cost drivers and the corresponding costs of products. However, because of efficiency variations of the manufacturers and suppliers, changes in supplier selections, market fluctuations, and several other reasons, certain...
The vast amount of information on the World Wide Web is created and published by many different types of providers. Unlike books and journals, most of this information is not subject to editing or peer review by experts. This lack of quality control and the explosion of web sites make the task of finding quality information on the web especially critical. Meanwhile new facilities for producing web...
The World Wide Web (WWW) has become one of the fastest growing electronic information sources. Recent years have seen a transformation in the type of content available on the web. Various IT reports show a rapid rise in the number of web pages in collaborative Web and social networking. The nature of the social media is user-granted content in front of one-sided traditional Web. As the availability...
The paper based on the wavelet transform to extract image edge and the necessary high-frequency information. Use a stable circular grid to identify and extract the features of the target image and the image to be matched. Use the simple Variance operation as the target function and combine with the genetic algorithm to optimize the target function. The results show that comparing with the other similar...
It is an important aspect of wavelet application that wavelet transform is used for signal compression, and the series of compactly supported orthogonal wavelet has outstanding local properties. This paper uses the method which combines the compactly supported orthogonal wavelet db4 with threshold method of minimax theorem to compress power quality disturbance signals. The concrete operation process...
