Moreover, in many cases, she has to resort to her colleagues and senior students to make comparisons among the candidates. The difficulties of...
The delay tolerant mobile sensor network distinguishes itself from conventional sensor networks by several unique characteristics such as node mobility, loose connectivity, and delay tolerability. Therefore, traditional data gathering methods cannot be applied. In this paper, a novel data gathering method named average contact probability-based data delivery scheme (ACPBD) is proposed. ACPBD introduces...
With the further researches on technologies in agriculture informationization in China, training systems based on these technologies got much development in recent years. However, there are still many problems in these systems, such as absenting interest. This paper uses classic Ceres-Maize model as maize growth model and Game Engine to develop an interactive agricultural training system based on...
According to the requirements of modularization and standardization, a general LXI bus interface based on ARM is presented in this paper and can be employed for HF ground wave radar (HF GWR). The design takes AT91RM9200, DM9161, IDT7027L20PF as basic hardware, Linux as operating system, and considers about the working environment of multi-users and multi-processes. The reliability of system can be...
