Group team communication serving for collaboration-work of special members, is an important application of MANET. In which, multicast protocol is a key technique to the group team application, which must guarantee the performance requirements: adaptable to the dynamic change of network topology, timeliness, minimizing routing overhead etc. This paper focuses on the improvement of MAODV applied to...
It is essential to consider drivers' perceptions and reactions when building Vehicular Cyber-Physical Systems (VCPS) since the effectiveness and efficiency of VCPS will largely depend on how drivers could benefit from such a system. This paper considers, for the first time, novel service scheduling problems from a Human Factors (HF) standpoint by taking into consideration the following fact: a driver...
A new online survey system is proposed. The system composes of back-stag system and foreground system, which to survey several building parameter. In the foreground, pan and laser distance measuring instrument is combine to measure the storey edge. Several algorithms is introduced which measure the building's height, width and length. The system according to actually situation propose K-mean cluster...
As the key point of the ontology research field, concept similarity computation has been widely used in the automatic question-answering systems. This paper firstly analyzes the existing concept similarity computation algorithm which is based on the semantic distance, and then proposes a new computation algorithm formula by modifying and adding some factors which can affect the accuracy of concept...
Automobile industrial wastewater contains high COD, which is complex and poor in biodegradability. Separated pre-treatment, coagulating sedimentation, biochemical treatment and advanced treatment were applied to treat Automobile industrial wastewater in this design. When pH value is in the range of nine to ten, it is the optimum condition to get rid of heavy metals. Three-stage-dephosphorizing technique...
This paper defines the concept of quality of life, and analyses the diffusion process about the event of blue-green algae in Taihu Lake. Based on this, it analyses the mechanism of how blue-green algae in Taihu Lake Affects the residents' quality of life, from five facets ,such as living standards, social support, the natural environment, the residents'quality of Leisure life, and the quality of sleep.
Driven by a number of significant internal and external environmental forces, the teaching quality of higher education has made great progress in the decade, but there are some distance between the reality and the demand. In this article, we discuss the current situation of the teaching quality. A framework is built to improve the teaching quality for a long time based on the Deming cycle and “the...
The traditional error control coding of channel has no long satisfied the requirement of the deep space communication, because of the long delay, great error rate, probability of packet loss, links easily interrupted and so on. The Fountain codes, used in deep space communication, has been introduced and analyzed. The coding and decoding process of LT codes of Fountain codes has been introduced and...
