Because of the worldwide aging population, more and more elders suffer from dementia. Nowadays, it is inconvenient and time-consuming for doctors to diagnose whether elders who live independently have dementia because lots of diagnostic questions on a checklist must be asked first, and part of them even require a long-term observation. In order to help doctors and make this diagnostic process easier,...
Numerous product information mobile applications (APPs) have been developed and their download counts are not negligible. The recommendation functions of Apps will help users to efficiently find related products and subsequently the user satisfaction will increase. This study aims to analyze pairwise comparison data using association rules to help the APP developer establish the recommendation system...
This paper proposed LSB Information Hiding algorithm which can Lift wavelet transform image. Furthermore, made the objective evaluation of image quality by the peak signal to noise ratio and normalized cross correlation coefficient. Achieving the purpose of information hiding with the secret bits of information to replace the random noise, using the lowest plane embedding secret information to avoid...
Based on two-port measurements, a distributed compact model and an extraction method for the power bus of a high-speed memory chip are proposed. The 1-D model is constructed according to the relative locations of the power and ground pads on the chip. The power bus around each power or ground pad is modeled by a section of resistor-inductor-capacitor (RLC) T-model, and the complete distributed model...
According to the linear relationship between the measuring data of Yangtze river, the index weight is decided by mean-variance method, triangle whitenization weight function and trapezoid whitenization weight function are established respectively to make grey evaluation for the present situation of water pollution of Yangtze river, finally the expectation results are approximate. This explains that...
A novel algorithm is proposed for CDMA cognitive radio (CR) system which introduces Nash game into distributed power control. We design an effective cost function, of which there exists the Nash equilibrium. The existence and uniqueness of the Nash equilibrium have been proved. Simulation shows that this new algorithm converges faster comparing to the other two classic algorithms while the signal...
This paper investigates the suppression of unwanted noise in high speed power buses by the adoption of photonic crystal power/ground layer (PCPL) structure. The performance of PCPL with different densities of high dielectric rods is analyzed in terms of S-parameters and electric field distribution. An attempt is made in order to relate geometrical properties (like rods' density and filling ratio)...
Modern credit risk management aims at assess the default probability (DP) of a debtor according to his historical and current financial data. Due to its prominent importance in credit loan decisions, the DP assessment becomes a research focus in the filed of financial data mining. To tackle this problem, we propose a nonlinear multi-parameter model (NMM) based on domain knowledge. Additionally, the...
Power saving is a critical issue in the IEEE 802.16e broadband wireless networks. In order to reduce the power consumption, the IEEE 802.16e provides three types of power saving classes (PSCs) for the Mobile Subscriber Stations (MSSs), where each PSC may contain one or several connections. However, how to define a PSC and assign PSCs to connections are open issues in the standard. Focusing on real-time...
A novel macro-via crystal (MVPC) structure is proposed for suppression of PPNs in high-speed or mixed signal circuit package. This structure is designed by periodically embedding macro-via cylinders, which consist of six vias and two circular pads, between the power and ground planes. Compared with previously proposed EBG structures, several advantages have been demonstrated. First, etching slots...
Selection of initial residuals affects parameter estimation. Until now, the mean of the residuals was widely employed as an estimate of initial residuals. In this paper, the statistics of the conventional method (i.e., using the mean of residuals as an estimate of initial residuals) are investigated. It is shown that the statistics of the conventional method depend directly upon the parameters to...
The primary objective of this paper is to provide a mathematical model of the full penetration process for the purpose of designing a control scheme. According to analysis of the practical welding, six typical welding conditions are selected to perform the dynamic experiments. In order to insure the validity of identified models, the experiments are designed accordingly. Based on the input/output...
