It simulates not only the transmission of network data and topology architecture, but also all kinds of IP network circumstance. This paper describes the architecture and characteristics of NS, and also gives the technique and the general process based on NS. The instance of a streaming media applications-based adaptive congestion control algorithm is implemented and simulation results are analyzed. The experimental result shows that when the network is congested, the delay, delay jitter and throughput will be corresponding changes in objective phenomenon.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127601847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jing","doi":"10.1109/ICCIS.2012.137","DOIUrl":"https://doi.org/10.1109/ICCIS.2012.137","url":null,"abstract":"Objective To evaluate the efficacy of artificial liver support system (ALSS) in the treatment of liver failure patients. Methods This is a multi-center, controlled, large sample clinic trial. 916 patients with liver failure from 6 hospitals were studied and followed. All the patients received similar pharmacological manipulation according to one and the same protocol but were divided into an ALSS treatment group and a control group without ALSS treatment. The analysis of survival time was computed using the Kaplan-Maier method, and comparison among groups was done using Log-Rank and Breslow test. Results Survival time of acute liver failure patients was prolonged from 4.0 days to 8.0 days. ALSS with many times increased the survival time of acute liver failure patients. In addition, it increased the survival time of the patients in end stage of liver failure. The survival time of end stage patients of the two times ALSS group and the control group was 51.0 days vs 27.0 days. Conclusion ALSS has tendency to prolong the survival time; ALSS has obvious effect on survival time of acute liver failure and prolong their survival time; ALSS can affect the short-term survival time of end stage patients; ALSS times have an obvious effect on survival time of liver patients especially the acute severe hepatitis and chronic severe ones and chronic repeat ones. Multi-ALSS treatment is more effective than the standard medicinal liver care treatment. Multi-ALSS treatment could increase survival time of patients suffering from acute liver failure or middle and end stage liver failure. It is important and necessary to treat these patients with ALSS.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127649791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multi-axis sensor generates coupled output signals inevitably because of the coupled structure or manufacturing errors. In order to minimize crosstalk in output signals, a compensation matrix which decouples the output signals is required. In this paper, the compensation matrix based on the least squares method will be derived. The LabVIEW is used in the experiment because the flexibility of LabVIEW makes the creation of user-friendly data acquisition (DAQ) programs and compensation algorithm. Finally, we will compare the performances of the multi-axis force/torque sensor before and after using compensation matrix in order to confirm the effect of this method.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131777166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The delay estimation of wormhole switching is mainly focused on average packet delay. But in order to provide Quality of Service (QoS) guarantees, we should analyze the end-to-end delay bound of wormhole switching. Based on models of Credit Stall and Switch Allocation Stall, we use arrival curve to constrain the arrival flow, and service curve to describe the service ability which system can guarantee to the arrival flow. Together with some fundamental theorems in Deterministic Network Calculus, we give the delay upper bound of flows in 3D-Torus network.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134539934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
