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":null,"pages":null},"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":null,"pages":null},"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.

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.

Since the existing marketing mechanisms can not fully take into account the key role of core group in the marketing process, the paper proposes a WVM core group marketing strategy (CGMS) to tackle this problem. CGMS overcomes the traditional marketing strategies' shortcomings which focus on the ex-post reward of customer's word of mouth behavior, or provide immediate compensation as incentives for the users according to their recommended behavior's costs. In addition, CGMS introduces the purchase rate concept. Based on user's purchase rate in network effects set (NES) of the core group, we combine with the core group's own properties to determine the marketing investment proportion so as to establish a rational CGMS. The experimental results indicate that the strategy can reduce the time consumption in the marketing mechanism, and improve the success rate of the recommended commodity effectively.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115585162","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}

In PaaS, one of the main problems is that if one of virtual machines' (VM) workload increases fast in a host, other VMs' performance characteristics may be influenced negatively. To solve the performance isolation problem, this paper gives a method. In this method, we use an algorithm to forecast all VMs' resources usage at first. Then we find which VMs' workloads may increase fast in future. We move these VMs to hosts which have more resources and other VMs' performance characteristics will not be affected at the same time. So the main problem now is which hosts we should use to move these VMs as mentioned above to. In this paper, we use Dynamic Programming method to solve this problem. So, with all of these algorithms, in this paper, we propose a strategy to solve Performance Isolation problem in PaaS.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117306630","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}

It is subjected to geo-stress in soft rock with rich water. Anisotropic mechanical-hydraulic coupling model was performed to investigate the energy density, effective stress and maximum shear stress, displacements and plastic zone of surrounding rock. Consequently, research results show that estimating pore water pressure distribution is important during construction. Energy, effective stress and the maximum shear stress accumulation zone occur and the peak value is located at 2.1 m from side wall. The displacement of crown is most and reaches to 7 cm which is less than ultimate displacement in teams of Code of Design on Tunnel of Railway. Extracted deformation ahead of working face is significantly affected when the distance is less than 8 m. Transversal plastic zone is mainly located at crown, shoulder and invert. The depth of it is 4 m. Pore water pressure and energy distribution ahead of working face increases firstly, and then it reduces. The peak value is located at 10 m ahead of working face.
