Intelligent Search Mechanism based on Neuro-fuzzy System for the Distributed Object Groups
Romeo Mark A. Mateo,Jaewan Lee 보안공학연구지원센터 2008 International Journal of Security and Its Applicat Vol.2 No.1
Current research in distributed systems focuses on object group models which are designed for scalable systems and provide accessible objects to the entire group. However, dynamic grouping using knowledge extraction from group of objects is not considered which provides accurate search for appropriate objects. In this paper, an integration of intelligent models in distributed object groups is presented in intelligent distributed framework. This paper proposes a locator service for the framework which implements the intelligent search mechanism based on neuro-fuzzy system. To have an accurate search of objects, the fuzzy system of the locator service is trained using the neuron-fuzzy algorithm. The proposed method is compared to other methods in accuracy of classification and result shows that it outperformed other algorithm based on processing time and accuracy.

In the town of Cabiao, as in other towns in the Philippines,Holy Week culminates in the commemoration of thepassion, death and resurrection of Jesus. Tableaux of theimages of Christ, Mary, the disciples and other saints -called santos - are borne in procession through the mainstreets of the town. Members of the town ‘élite’commissioned the images and now stage the processions. To better understand their role, this paper analyses thedynamics of this form of sponsorship, including thesystems, structures and practices of santo patronage,using the older images to help identify sponsors in theSpanish period. I used documents to find out more aboutthe background of members of this élite – the estates andproperties they owned and the political posts they held. The manuscripts also gave some clues about how and whythe sponsorship of santos developed as it did in the mid-19th century. NB. ‘Élite’ is used here to refer to a particular strata ofPhilippine rural society. It does not have the negativeconnotations (uncaring wealth and privilege) that the termsuggests in many other parts of the English-speakingworld.
Scalable Search based on Fuzzy Clustering for Interest-based P2P Networks
( Romeo Mark A. Mateo ),( Jaewan Lee ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.1
An interest-based P2P constructs the peer connections based on similarities for efficient search of resources. A clustering technique using peer similarities as data is an effective approach to group the most relevant peers. However, the separation of groups produced from clustering lowers the scalability of a P2P network. Moreover, the interest-based approach is only concerned with user-level grouping where topology-awareness on the physical network is not considered. This paper proposes an efficient scalable search for the interest-based P2P system. A scalable multi-ring (SMR) based on fuzzy clustering handles the grouping of relevant peers and the proposed scalable search utilizes the SMR for scalability of peer queries. In forming the multi-ring, a minimized route function is used to determine the shortest route to connect peers on the physical network. Performance evaluation showed that the SMR acquired an accurate peer grouping and improved the connectivity rate of the P2P network. Also, the proposed scalable search was efficient in finding more replicated files throughout the peer network compared to other traditional P2P approaches.

The key issue in providing fast and reliable access on cloud services is the effective management of resources in a cloud system. However, the high variation in cloud service access rates affects the system performance considerably when there are no default routines to handle this type of occurrence. Adaptive techniques are used in resource management to support robust systems and maintain well-balanced loads within the servers. This paper presents an adaptive resource management for cloud systems which supports the integration of intelligent methods to promote quality of service (QoS) in provisioning of cloud services. A technique of dynamically assigning cloud services to a group of cloud servers is proposed for the adaptive resource management. Initially, cloud services are collected based on the excess cloud services load and then these are deployed to the assigned cloud servers. The assignment function uses the proposed proportional ordering which efficiently assigns cloud services based on its resource consumption. The difference in resource consumption rate in all nodes is analyzed periodically which decides the execution of service assignment. Performance evaluation showed that the proposed dynamic service assignment (DSA) performed best in throughput performance compared to other resource allocation algorithms.
WEAKLY DENSE IDEALS IN PRIVALOV SPACES OF HOLOMORPHIC FUNCTIONS
Romeo Mestrovic,Zarko Pavicevic 대한수학회 2011 대한수학회지 Vol.48 No.2
In this paper we study the structure of closed weakly dense ideals in Privalov spaces N^p (1 < p < ∞) of holomorphic functions on the disk D : <수식>. The space Np with the topology given by Stoll's metric [21] becomes an F-algebra. N. Mochizuki [16] proved that a closed ideal in N^p is a principal ideal generated by an inner function. Consequently,a closed subspace E of N^p is invariant under multiplication by z if and only if it has the form IN^p for some inner function I. We prove that if M is a closed ideal in Np that is dense in the weak topology of N^p, then M is generated by a singular inner function. On the other hand, if Sμis a singular inner function whose associated singular measure μ has the modulus of continuity <수식> then we prove that the ideal SμN^p is weakly dense in N^p. Consequently, for such singular inner function Sμ,the quotient space N^p=SμN^p is an F-space with trivial dual, and hence N^p does not have the separation property.
Healthcare Expert System based on Group Cooperation Model
Romeo Mark A. Mateo,Jaewan Lee,Bobby D. Gerardo 보안공학연구지원센터 2008 International Journal of Software Engineering and Vol.2 No.1
Expert systems for healthcare are widely studied where accuracy of diagnosis and efficiency of the system for various healthcare services are examined. Also, recent researches include decision support services, expert medical services and autonomous management, which are based on multi-agent systems. The cooperation of agents is crucial in analyzing, and managing the data of patient in order to detect abnormal patterns so that it can provide an advance treatment. This research shows the implementation of healthcare expert system (HES) based on group cooperation model. Communications through the components of the group cooperation model are designed based on multi-agent approach. The proposed agent managers effectively coordinate the processing of client requests. Replica managers provide quality of service for clients by replicating objects. An adaptive scheme using round robin and fuzzy least load algorithms is managed by load balancing service. And in this paper, we presented the implementation by using CORBA for distributed objects and Jade Framework for agents..

<P>Induction of apoptosis is a promising strategy that could lead to the discovery of new molecules active in cancer chemotherapy. This property is generally observed when cells are treated with agents that target microtubules, dynamic structures that play a crucial role in cell division. Small molecules such as benzo[b]furans are attractive as inhibitors of tubulin polymerization. A new class of inhibitors of tubulin polymerization based on the 2-(3',4',5'-trimethoxybenzoyl)benzo[b]furan molecular skeleton, with the amino group placed at different positions on the benzene ring, were synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization, and cell-cycle effects. The methoxy substitution pattern on the benzene portion of the benzo[b]furan moiety played an important role in affecting antiproliferative activity. In the series of 5-amino derivatives, the greatest inhibition of cell growth occurred if the methoxy substituent is placed at the C6 position, whereas C7 substitution decreases potency. The most promising compound in this series is 2-(3',4',5'-trimethoxybenzoyl)-3-methyl-5-amino-6-methoxybenzo[b]furan (3 h), which inhibits cancer cell growth at nanomolar concentrations (IC(50) =16-24 nM), and interacts strongly with tubulin by binding to the colchicine site. Sub-G(1) apoptotic cells in cultures of HL-60 and U937 cells were observed by flow cytometric analysis after treatment with 3 h in a concentration-dependent manner. We also show that compound 3 h induces apoptosis by activation of caspase-3, -8, and -9, and this is associated with cytochrome c release from mitochondria. The introduction of an α-bromoacryloyl group increased antiproliferative activity with respect to the parent amino derivatives.</P>
