Comparing to TCP traffic, the composition of UDP traffic is still unclear. Although it is observed that a large fraction of UDP traffic appears to be P2P applications, application level classification of UDP traffic is still very hard since most of these applications are private protocols based. In this paper, a novel method is proposed to classify UDP traffic. Based on the assumption that traffic...
The current study shows, as the "sea spikes" like the target signal, there is great impact on target identification, Therefore, the identification of sea spikes is particularly important. it is possible to separate the spikes from the sea background by using three sea-spikes defining parameters, the spike amplitude, the minimum spike width and the minimum interval between spikes. We pay...
Symptoms and signs (symptoms in brief) are the essential clinical manifestations for traditional Chinese medicine (TCM) diagnosis and treatments. To gain insights into the molecular mechanism of symptoms, this paper presents a network-based data mining method to integrate multiple phenotype-genotype data sources and predict the prioritizing gene rank list of symptoms. The result of this pilot study...
The paper begins with discussion on Aspect-Oriented programming (AOP), including its concept, thought, development, and advantage in handling crosscutting concerns, followed by description of the theory of constraints. Furthermore, combined AOP with first-order logic language, a new method to detect the business constraints in requirement analysis is presented, which is simple and practicable, thus...
This system mainly aims at the design of communication system for autonomous mobile robot intelligent system, mobile robots can complete the function that is sensory of the outside world such as the situations and changes of surrounding environment based on multi-sensor information fusion, can identify obstacles through ultrasound and infrared sensors. Multiple control various information accessed...
Geosmin (GSM) and 2-methyl isoboneol(2-MIB) are the major compounds causing the odor of water body. A new method for the qualitative and quantitative analysis of GSM and 2-MIB, which isolated and enriched the odor compounds from the water samples by using Headspace solid-phase micro extraction (HS-SPME), and detected the two substances using GC/MS with internal standard method, was developed. The...
In order to optimize target temperature, holding time and NaOH dose on solubilization degree of thickened waste activated sludge, a combined NaOH-microwave pretreatment process was studied on the basis of uniform design method. The results indicated that the variables markedly affected the solubilization degree of chemical oxygen demand (COD). The optimal conditions were determined and two-dimensional...
In the knowledge-based economy, the triple helix of university--industry--government relations has constructed a new innovation model. The triple helix theory suggests that there exists a symbiotic relationship as the structure of DNA spirals among industry, university and government which are the leading actors of creative city. This paper explores the mutual relations of the three actors and their...
