The paper presented the Medical Wireless Sensor Network model with combining battery energy, environment energy and human body energy to provide energy supply. Also, the paper discussed sensor node planning designed by means of ZigBee technology. After combining the application of Internet, it could not only carry out remote localization, but also ensure the accuracy, sensitivity and safety of close monitoring.
Abstract. RNA secondary structure study is one of the most important fields in computational molecular biology. According to different conditions, RNA secondary structure prediction derives two ways. In the paper, the method to predict RNA secondary structure is introduced in two ways. It includes the mathematic models and main algorithms. The paper also points out the existing problems. The main development directions of RNA secondary structure prediction algorithm is also be indicated.
Firstly, several common vertical anti-seepage forms for modern sanitary landfill are reviewed and compared. According to the unreasonable calculation method of the wall thickness in the New Code, this paper proposes a reasonable calculation method of the wall thickness through the two engineering project cases: valley type and plain type landfill, reflecting on the reasonable choice of the vertical anti-seepage forms. For the valley type landfill where the cover layer has a certain thickness, jet grouting pile and post grouting is proposed for the anti-seepage; for the plain type landfill whose foundation is composed of clay or sandy soil, the cement mixing pile is proposed for the anti-seepage.
Discrete-element-method (DEM) codes were developed in the field of rock mechanics. Compared to continuum codes, it has many advantages such as allowing larger grain displacements, detachment of grains, and simulation of discrete fractures. However, the disadvantage of DEM codes in the simulation of higher confining pressure triaxial tests were not previously discussed. In this study, we explored how the non-Dirac-delta distribution of contact forces controls the fault rupture initiation, and its impact on fault rupture propagation under high confining pressure. Based on the above study, a novel local dynamic weakening model was proposed and incorporated into the smooth-joint (SJ) contact model. The dynamic weakening model is tested with simulations of experiments conducted under high confining pressures. It is shown to be successful at reproducing realistic fault rupture behaviors, and the synthetic acoustic emission (AE) characteristics including magnitude-frequency relationships and fractal dimensions match those in the experiment.
The application of mobile ECG detection plays an important role in finding out what the heart conditions are. It will prevent and treat the cardiovascular disease. At present, it is hard to exchange the information in various heterogeneous systems. HL7 standard specifies the medical information transfer format, and improves the degree to share the data among the medical information systems. Based on HL7 standard and web service technology, this paper designed HL7 engine to realize the seamless data transfer among the heterogeneous systems, and enable sharing and interaction of ECG information, as well as improve the working efficiency and competitiveness of medical system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
