This paper analyzes the performance of a cognitive underlay system over Nakagami-m fading channels, where maximal ratio combining (MRC) is employed at secondary destination and relay nodes. Under the condition of imperfect channel state information (CSI) of interfering channels, system performance metrics for the primary network and for the secondary network are formulated into exact and approximate expressions, which can be served as theoretical guidelines for system designs. To verify the performance analysis, several analytical and simulated results of the system performance are provided under various system and channel settings.

Care transitions are key to patient safety and remain a safety issue despite previous research. This study examines how the design of care transitions impacts different health care professions. Twenty-nine physicians and nurses were interviewed about operating room to intensive care unit care transitions. We compared relationships between work system elements in positive and negative opinions about two sociotechnical system designs: including team or individual handoffs. Nurses did not express positive opinions of individual handoffs or negative opinions of team handoffs, while physicians expressed positive and negative opinions of both. Relationships between work system elements varied by profession in the positive opinions about team handoffs and negative opinions about individual handoffs. Professional needs and culture may be related to the different perceptions of each handoff. Future work should continue to examine professional differences when developing a flexibly standardized process to ensure all users are considered.

The concept of a signature is a useful tool in the analysis of semicoherent systems with continuous, and independent and identically distributed component lifetimes, especially for the comparison of different system designs and the computation of the system reliability. For such systems, we provide conversion formulae between the signature and the reliability function through the corresponding vector of dominations and we derive efficient algorithms for the computation of any of these concepts from any other. We also show how the signature can be easily computed from the reliability function via basic manipulations such as differentiation, coefficient extraction, and integration.

China is a big agricultural country, effective prediction of peasants’ income is very important. This study mainly uses the SVM theory to predict the peasants’ income. By analyzing the influence factors of peasants’ income, establishes the index system, that is corresponding relationship of peasants’ income and factors of social influence, According to this index system, designs the prediction method of peasants’ income based on SVM. Bases on the statistical data of social factors and peasants’ income between 1990-2012 in china, to train the SVM model, at the same time, the kernel function and parameters of SVM used were setting and compared. The experimental results show that the accuracy of RBF function is 90.7%, the time is 98ms, has higher accuracy and faster computing speed.
