Intuitionistic Fuzzy Optimization of Truss Design: A Comparative Study

Abstract: In this paper, we have developed an intuitionistic fuzzy optimization (IFO) approach considering non-linear membership and nonmembership function for optimizing the design of plane truss structure with single objectives subject to a specified set of constraints. In this optimum design formulation, the objective functions are the weight of the truss; the design variables are the cross-sections of the truss members; the constraints are the stresses in members. A classical truss optimization example is presented here in to demonstrate the efficiency of the Intuitionistic fuzzy optimization approach with non-linear membership function. We made a comparative study of linear and non-linear membership and non-membership function to see its impact on intuitionistic fuzzy optimization and to get to the depth of such optimization process. The test problem consists of a two-bar planar truss subjected to a single load condition. This single-objective structural optimization model is solved by intuitionistic fuzzy optimization approach with nonlinear membership and non-membership function. Numerical example is given to illustrate our approach. The result shows that the IFO approach is very efficient in finding the best discovered optimal solutions. Keywords— Intuitionistic fuzzy optimization, Nonlinear membership function, Non-linear nonmembership function, Structural design.

Virtual Reality in Cognitive Rehabilitation

Abstract: The studies of topographic disorientation from brain injury focus on describing impairments, specifying neuroanatomical correlates of topographic disorientation, and categorizing types of topographic disorientation. Models of environmental cognition have been applied in some studies of topographic disorientation. The study is done here to develop a system that analyses the spatial behaviour of the individual and train the ones with poor spatial visualization and navigation skills in an optimal way so that they can maintain orientation during navigation. Virtual Reality provides the best tool for the rehabilitation and assessment of topographical disorientation. Therefore, using virtual reality technique, a virtual environment has been created as the part of study and the subjects have been exposed to it in order to treat the spatial impairment. For creating the virtual environment, Unity Game engine is used.

Enhancement in AOMDV Protocol to Reduce Chances of Link Failure in Mobile Adhoc Network

Abstract: MANET is a self configuring network which has no fixed infrastructure. Topology in MANET changes frequently. During data transmission, there is a problem of link failure which degrade the performance of the network. The nodes are deployed in the network and path is established according to EAOMDV protocol from source to destination. There are some nodes in the path having much movement than other nodes. Due to these nodes link failure problem occurs. So link failure problem is responsible for performance degradation and low reliability of the network. In this paper, a novel technique is proposed to overcome link failure

A Novel Ensemble Based Decision Tree Model For High Dimensional Biomedicine Data

Abstract: Knowledge discovery is an essential mechanism for the intelligent data analiysis to transform data in to meaniful information that will support for decision making. Data mining approaches support automatic exraction of data, and attempts to discover the hidden rules and patterns in data, and also detact relevant decision rules from the high dimensional dataset. Classification from imbalanced data is significantly affected the performance of the algorithm due to noise and high dimensionality. Sparsity and high dimensionality of the classifier algorithm becomes a major problem in many traditional decision tree models on medical datasets. A novel decision trees allows estimating on topmost features to assess the class prior probability and estimates the chance of misleading false positive patterns. In this research work, a new framework is proposed by integrating random forest decision tree for pattern analysis. Experimental results show that proposed model has better accuracy compare to existing approaches.

State of art ontological infrastructure for Cloud Computing

Abstract: During the past few years, cloud computing has become a key IT buzzword. Although the definition of cloud computing is still “cloudy”, the trade press and bloggers label many vendors as cloud computing vendors, and report on their services and issues. Cloud computing is in its infancy in terms of market adoption. However, it is a key IT megatrend that will take root. Though the cloud computing has great features such as on demand self service, resource pooling and rapid elasticity there is a shortage in cloud computing because it hasn't provided a unique semantic ground as that of Semantic Web . So, in order to provide an environment for automatic searching of services, resources ontology is used. These are some of the areas where Ontology is used in Cloud Computing. Ontology based registries are used for dynamic discovery of cloud computing resource across various cloud computing platforms, It can be used to provide intelligent customization framework for Saas and easing the design of security system by proving role based access control using ontology.

Investigating the Impact of Node deployment models on the performance of OSPF Routing Protocol in MANETS

Abstract: Mobile Ad-hoc Networks (MANETs) are wireless network with mobile nodes. Mobile means the nodes are free to move themselves randomly, which may cause the rapid and unpredictable change of the network topology. Ad-hoc means that each node is willing to forward data for other nodes. In this paper we investigate the impact of three node deployment models namely grid, random and circular on the performance of Open shortest path first (OSPF) by using OPNET Simulator (v14.5). Simulation results show that Random deployment model perform better than grid and circular deployment models.

Amended Anticipation Model for Fast Exposure of Mischievous Communications in Database Systems

Abstract: Database Security is an concept that includes the following properties: authenticity (guarantees that a service or piece of information is authentic), confidentiality (absence of unauthorized disclosure of a service or piece of information), integrity (protection of a service or piece of information against illicit and/or undetected modification), and availability (protection of a service or piece of information against possible denials of service caused by malicious actions). Current intrusion detection systems use logs to detect malicious transactions. Logs are the histories of the transactions committed in the database. The disadvantage of using logs is that they need lot of memory. In addition to this sometimes even after a transaction is detected as malicious it cannot be rolled back. In this paper we present a method by which we can overcome the uses of logs and can detect malicious transactions before they are committed. We use specific user-profiles to store the sequence of commands in a transaction and use a prevention model for instant detection of malicious transactions.
