The multimedia data under Spark cloud computing platform are composed of many different types of entities, and all kinds of entity attributes are not exactly same. The traditional multimedia data clustering process based on spectral clustering algorithm assumes that multimedia data are composed of independent entities of the same type, and entities are unrelated with the obtained clustering results giving significant erro Read More

In the process of multimedia network image transmission for image compression processing #140;the current image processing algorithms only rely on the existing node energy for the compression and transmission#140;without considering the digestive problems that image data will transmit itself, leading to image resources selection restriction and poor image compression effect. The multimedia network image tran Read More

As a data mining tool, time series facilitates better understanding nature of the development process of things and permits forecasting the future values of the process parameters based on the data recorded in a chronological order. ARIMA is one of the general time series models and capable of representing time series which, although not necessary stationary, is homogeneous and in statistical equilibrium. This paper presents Read More

During the research process of multimedia image coding method, due to the large amount of data in multimedia image, the nonlinearity interference is produced in the transmission, storage and processing. When the traditional method is adopted for research, the bandwidth occupied by channel is affected by interference, resulting in no guarantee for the quality of the reconstructed image. In this paper, a multimedia i Read More

In the process of network multimedia data compression, due to limited network resources and redundant data transmission, the traditional compression algorithm for network multimedia data based on wavelet transform will waste communication bandwidth and energy, as it greatly reduces the efficiency of data compression, because all network multimedia data need to carry out wavelet transform one by one. Ther Read More

The traditional multimedia image mining based on association rules, has a big flaw in mining time, thus a multimedia image mining method based on fuzzy pixel difference iterative clustering is proposed. In this method, multimedia image index characteristic value is converted into relative membership degree for fuzzy concept index. On the basis of the multimedia image samples and fuzzy pixel difference comprehensive tr Read More

In the scheduling process of massive data in multimedia network, randomness is high, and calculation process is complex, resulting in large amount of calculation during traditional massive data scheduling process. A massive data scheduling model in multimedia network is proposed based on POMDP, to analyze the drawbacks of the traditional model and introduce the general POMDP model. The parameters related to multime Read More

This paper presents the design of a micro-strip antenna which adopts coplanar waveguide to feed electrical wave, the antenna and metal radiator floor which are fixed on the same antenna plane to reduce the antenna's size. The designed antenna satisfies the needs of conformal and integrated disposal of the antenna. Antenna structure adopts square heart-shaped metal radiator, which belongs to the gradient line pat Read More

With the development of digital watermarking technology, digital watermarking protocol is now drawing the attention for protecting copyrights of digital products. However, the copyright protection is fully protected by watermark technology if it is employed a suitable protocol between the rights owner and the customer. Therefore, currently, there are a number of buyer-seller watermarking protocols proposed, however, an Read More

This paper proposes a Modified Fractional Order PI controller (MFO-PI) for grid connected variable speed Wind Energy Conversion System (WECS). The proposed MFO-PI employs an integer integral action and fractional order integral action, and a supervisor to select the more suitable integral action looking for the working conditions. The parameters of the MFO-PI controller have been tuned using frequency method to realize t Read More

The devices in the intelligent substation are required to transmit and process information in Smart Grids. On account of the modular design technology, serial port communication becomes the main technique used to connect intelligent modules as its high reliability, flexibility, and ease-of-use features, which is also used in the communication of the data collection board and the conversion board of the three-phase circui Read More

Background: In traditional temperature protections for dry-type transformers, a transformer is switched off when its temperature is over a high threshold value. Because the actuation time is too long, the transformer will suffer from very high temperatures. In order to overcome the problem, a faster temperature protection based on temperature variation acceleration algorithm is developed. Methods: By studying th Read More
