Due to the great advantage in lighting and decoration, neon lamps that play a significant role in our daily life are widely utilized. Most researches of neon lamp system concentrate on the luminescence characteristic and discharge performance, paying little attention to the electromagnetic radiation. Therefore, this paper contributes to it and carries out a research on the electromagnetic radiation...
DSA(Digital Signature Algorithm) algorithm is widely used in the digital signature fields. With the arrival of the era of big data, it has been put forward higher requirements for the operation speed of variety of digital signature algorithm. An improved speed algorithm isDSA (Improved Speed DSA) is presented, which is based on the idea of avoiding the complex and time-consuming modular inverse. In...
Security in wireless sensor networks (WSNs) is very important. Traditional security schemes abandon compromised nodes and add a lot of redundancies to make the network resilient. These methods are not applicable to resource-limited WSNs. This paper proposes an adaptive and active defense mechanism with low power consumption. In our scheme, some nodes are configured as monitoring nodes to identify...
This thesis employs two OLG Models to analyze the partially funded pension system in China, and proves that the reduction of the population growth rate will lead to the increase of the payment rate. And intergenerational transfer rate between two generations will improve. The ascending of the enterprise payment rate during political-economy equilibrium is determined by the decline of capital output...
Privacy is a very important issue when storing electronic medical records. According to the definition set out in the Health Insurance Portability and Accountability Act (HIPPA), the confidential section of the electronic medical record needs to be protected. Thus, a mechanism to protect the patient's privacy is needed during electronic medical record exchange and sharing. The privacy protection mechanism...
Crime mapping is a very effective method for detecting high-crime-density areas known as hot spots. Crime hot spot is an area where the number of criminal or disorder events is larger than that in any other places, or an area where people have a higher risk of victimization. There are many theories and methods in common use by far. They explain different types of crime phenomena that occur at different...
In order to satisfy the course needs of web database programming, this paper introduces a research teaching platform based on IIS environment. Students can cooperatively do the research project according to the teacher arrangement, and upload the research reports and web page works to the web server for communication and evaluation. The system takes a serious of measures for the security protection...
This paper studies shortest addition chains algorithm of modular exponentiation, modifies the expression of modular exponentiation according to Euclid algorithm, transform the process of solving the shortest addition chains of a large integer into solving that of three much smaller integers, then greatly saves the time and space of the process, and ensures that the length of new shortest addition...
