The efficient measurement and management systems for the credit risk in individual loan should be urgently established. Such systems need a knowledge-based decision methodology to be implemented. The decision tree algorithm is one of methods. It is applicable to enhance the riskpsilas assessment of Chinese individual real-estate loan. It has several advantages such as understandable principle, low demand, and interpretable results that can be visualized. In this paper, the decision tree and information entropy theories are applied to the credit-risk assessment of individual housing. Based on the theory of decision tree and domain knowledge, the evaluation of attribute to measure important degrees by knowledge-based information gained and a theoretical structure equation was established. It was found that using such approach, a higher accuracy for forecasts can be reached.","PeriodicalId":122953,"journal":{"name":"2008 International Multi-symposiums on Computer and Computational Sciences","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114979722","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 main property of self-healing key distribution is that the users are capable of recovering lost session keys on their own, without requesting additional transmissions from the group manager. In this paper, we propose a self-healing key distribution scheme with t-revocation and 2t-collusion resistance capabilities for wireless sensor networks. Built on an appropriate security model, our scheme reduces both storage and communication overhead and eliminates the limitations of m sessions when compared with some previous work under the same security model. In addition, we propose a scheme which enables key recovery from a single broadcast message.","PeriodicalId":122953,"journal":{"name":"2008 International Multi-symposiums on Computer and Computational Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117147973","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}

However, there is almost no considered one about existing routing protocols of sensor network because it is difficult to apply congestion control in transport layer of WSNs (wireless sensor networks) that have limited resources such as energy, buffer, and bandwidth of sensor nodes. Therefore, routing protocol of sensor networks must deliberate how to control congestion. In order to overcome this problem, we propose the routing protocol avoidable congestion to improve throughput, packet drop rate, lifetime, and so on. Consequently, each node can evenly distribute loads. We demonstrate how to achieve congestion-free load balancing when there are multiple routing paths towards sink.","PeriodicalId":122953,"journal":{"name":"2008 International Multi-symposiums on Computer and Computational Sciences","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131872752","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 preferred to be conducted as the control-based defense. However, some existed methods have their respective disadvantages, such as efficiency, privacy. Therefore, a DDoS-oriented distributed defense framework based on the edge router feedbacks in autonomous systems (AS) is proposed to thwart the attack traffic in the boundary of AS near to the attacking sources. In the attacks, by measuring its ingress traffic rate the victim sends the feedbacks to the edge routers, as a result that malicious traffic is effectively filtered in AS boundary. The experiments show that the distributed defense framework can effectively guarantee the survival rate of legitimate flows and protect the victims in AS from DDoS.","PeriodicalId":122953,"journal":{"name":"2008 International Multi-symposiums on Computer and Computational Sciences","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128526879","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}

Through analyzing the tumor shape pattern on the clinical images and the experimental results, we find that the tumor shape can be characterized on three aspects: convexity, ellipticity, and symmetry. In this paper, the shape measures are quantified using the polygonal approximation, the fitting ellipse, and local area integral invariant of contour respectively. The performance of these shape measures is evaluated on a breast ultrasound image data of 87 cases (49 benign and 38 malignant). Two combined convexity measures, an elliptic compactness, and a new reflection symmetry measure from local area integral invariant among the shape measures are appropriate and effective for distinguishing malignant and benign tumors, and all of their area under ROC curve can reach 0.9. They are significantly different between benign and malignant tumors on sonography, and show potential for the malignant risk assessment.","PeriodicalId":122953,"journal":{"name":"2008 International Multi-symposiums on Computer and Computational Sciences","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133809061","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}

With the growing crystal structures of protein-DNA complexes, the computational approaches are becoming more and more useful for modeling protein-DNA interactions. This paper proposes template-based alignment with a new scoring function which combined the evolutionary conservation and protein-DNA interacting scores of DNA-contact residues. We showed that the combined scoring function is better to model the protein-DNA interactions than applying only one. Our method achieved high accuracy in identifying DNA-binding domains of 69 representative families and with the correlation 0.6 in predicting the binding free energy of the alanine scanning data. By applying the method to the hormone receptor family, it showed that our method can identify the DNA-binding specificity in different subfamilies. The evolutionary conservation is able to reflect the evolution pressure of DNA-contact residues and the interaction preferences can indicate the binding affinity between the protein and DNA. Experimental results show that both the evolution conservation and the DNA-binding capability of the DNA-contact residues are essential for identifying DNA-binding domains and protein-DNA interactions.","PeriodicalId":122953,"journal":{"name":"2008 International Multi-symposiums on Computer and Computational Sciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114258109","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}
