Wi-Fi has been widely deployed with the rapid development of wireless communication technique. Wi-Fi hotspots are popular in campus, making convenient wireless network access possible. However, during class teaching, in order to avoid students browsing the web based on Wi-Fi hotspots and distracting, we hope Wi-Fi hotspots adaptively shield network access to students in the classroom, while grant...
Through the analysis of the reliability and validity for historical data of the students' evaluation of teaching, it is found that teacher-centered evaluation index system is the main reason for the decrease of the reliability and validity of the evaluation results. Therefore, a new evaluation index system with the students as the subject is constructed on the basis of extensive solicit their opinions,...
This study focuses on using ultrasound (US) biomarkers for characterizing myopathies and in particular myositis. US offers an opportunity to deliver diagnostics in clinical settings at a fraction of the cost and discomfort entailed in current workflows. US is also better suited for usage in under-resourced environments. This paper is focused on studying the link between biomarkers related to absolute...
Link prediction in complex network often focuses on the single network in many fields and develops a lot of methods. However, the relationship between two dependent networks with specific global structure has hardly caught attention, but only the local topology analysis. In this paper, we aim to infer the correlation of two high dimensional dependent networks based on the similar nodes' attributes...
It is known that the muscles actuate human hand joints with a coordinated manner and the hand postures can be reconstructed by a few (usually two) inputs through postural synergies, which has been applied in robotic hand design for reproducing the human versatile grasp function. As for the mechanical implementation, in terms of the joints implemented postural synergies, due to the excessive number...
Measures of complex network analysis, such as vertex centrality, have the potential to unveil existing network patterns and behaviors. They contribute to the understanding of networks and their components by analyzing their structural properties, which makes them useful in several computer science domains and applications. Unfortunately, there is a large number of distinct centrality measures and...
A system for automatically evaluating singing enthusiasm is proposed in this study. The definition of singing enthusiasm is how much enthusiasm is perceived in a song being evaluated. This system evaluates the singing enthusiasm on the basis of pitch accuracy, vibrato, diminuendo, roughness, and the correlation between pitch and loudness. A support vector regression (SVR) machine is used for the evaluation...
SM4 is a 128-bit block cipher used in the WAPI (Wireless LAN Authentication and Privacy Infrastructure) standard for protecting data packets in WLAN. This paper proposes a novel method of CPA (Correlation Power Analysis) on SM4 based on chosen-plaintext. Using SM4 as target algorithm, Sakura-G FPGA board as hardware verification platform, we only collect 1000 power consumption waveforms to obtain...
Most of papers on image encryption provide some measures to attest that the presented works satisfy the required criteria in the field. Some others propose a comparative study and decide on whether one work is better than another one always using these measures. These last are of different types where the correlation coefficient is one among them. It is a statistical measure used to analyze the resemblance...
The researches relevant to age-related changes have been the significant subject causing more and more attraction. This study is to investigate age-related changes of event-related potentials with detrended partial cross-correlation analysis (DPCCA) [11,12] to explore the discrimination between the young and the older. We hypothesized that the DPCCA coefficients were affected by age-related changes...
In a low signal / noise ratio, shape deviation of detected signals causes them pass. The task of neutralization of this effect is classified as actual one. In active control systems it is proposed to solve the task through result tracing operation of reactions comparison for controlled and reference objects on sounding effects. The most probable one is selected according to similarity degree of possible...
This paper presents the development of decision support model through the development of an information system JKP Parking servis Kragujevac. This paper is an attempt of approaching the classical methodology and modern demands of information systems for creation of effective decisions. The paper proves that the design of an information system is inseparably from the process of decision-making and...
Unavoidable process random variation causes mismatches to deviate the performance of many analog circuit blocks. In addition, the correlation between components is also related to the performance parameters of analog circuits. This paper proposes a layout strategy to reduce the random error by making the trade-offs among performance parameter, correlation coefficient, and area allocation cost. Simulation...
With the growing market of IP movies, it's becoming more and more important to know their box office features. This paper studies the influence degrees on the film box office from IP features, including the IP type, rating score and following number, combined with other factors that affect the film box office. By using the 2015 data of the films shown in China, the empirical analysis is conducted...
Consumers usually evaluate storage time of a beef, as well as its freshness, using its surface color. However, in this study, by using a colorimetric method, we found that the surface color change of beef samples was unrecognizable during the first five days of storage. On the other hands, the attenuance difference between 615nm and 630nm (A630-A615 difference) was found to have a high correlation...
The short-term load forecasting error highly affects the security and economic operation of power systems. The load in different areas are distinct in the composition of consumers, impact factors, and profiles, and are thus of different forecast ability. Understanding the correlations of load forecast error among different areas would provide significant insight on the ways of managing the forecast...
Capillary images obtained from the finger nailfolds are very useful for diagnosis of the health condition of a person. Specific capillaroscopic patterns have been identified for healthy controls as well diseases such as Systemic Sclerosis and Raynaud's phenomenon. Here, six capillary morphological abnormalities act as inputs to response surface regression, generating an output whose range will indicate...
Objective of the paper is to evaluate metrics of automatic evaluation of machine translation output using manual metrics — fluency and adequacy. We tried to answer the question to which extent the manual evaluation correlates with the automatic evaluation of MT output from/to Slovak to/from English. We focused on metrics based on the similarity and statistical principles (WER, PER, CDER and BLEU-n)...
With the increase of multi media technology and internet there is a rapid growth in storing and retrieving of documents. Government has taken several methods for documents to scan and stored digitally for future use. Even though the documents are available in the digital format, but it is very difficult to search for a single word or phrase. Traditional optical character recognition techniques (OCR)...
With the increasing number of applications for security in small devices and short lived transactions services, and the encryption algorithm which we need is faster, more convenient, and more secure. TEA is one of them. In this paper, there are four experiments with 64 and 128 bit size key TEA. The results of the experiments proving that TEA cannot defend Bitsum Attack. The reason is in TEA the bitsum...
