Abstract”
It is a major challenge to process high-dimensional measurements for failure detection and localization in large-scale computing systems. However, it is observed that in information systems, those measurements are usually located in a low-dimensional structure that is embedded in the high-dimensional space. From this perspective, a novel approach is proposed to model the geometry of underlying data generation and detect anomalies based on that model. We consider both linear and nonlinear data generation models. Two statistics, ....etc

SECURE WIRELESS SENSOR NETWORKS - ROBUST OF WSN ATTACKS AND SECURE LOCALIZATION SCHEME
ABSTRACT
The application of wireless sensor networks (WSN), sensors are deployed un-tethered in hostile environments. For location aware WSN applications, it is essential to ensure that sensors can determine their location, even in the presence of malicious adversaries. Our paper mainly projects the problem of enabling sensors of WSN to determine their location in an un-trusted environment. The localization schemes based ....etc

Knowledge of the complex molecular structures of living cells is being accumulated at a tremendous rate. Key technologies enabling this success have been, high performance computing and powerful molecular graphics applications, but the technology is beginning to seriously lag behind challenges posed by the size and number of new structures and by the emerging opportunities in drug design and genetic engineering. A visual computing environment is being developed which permits interactive modeling of biopolymers by linking a 3D molecular graphics ....etc

HBA DISTRIBUTED METADATA MANAGEMENT FOR LARGE SCALE CLUSTER BASED STORAGE SYSTEM --PARALLEL AND DISTRIBUTED SYSTEMS

Abstract: An efficient and distributed scheme for file mapping or file lookup is critical in decentralizing metadata management within a group of metadata servers, here the technique used called HIERARCHICAL BLOOM FILTER ARRAYS (HBA) to map filenames to the metadata servers holding their metadata. The Bloom filter arrays with different levels of accuracies are used on each metadata server. The first one with low accuracy and u ....etc

Abstract
Localization is an essential and important research issue in wireless sensor networks (WSNs). Most localization schemes
focus on static sensor networks. However, mobile sensors are required in some applications such that the sensed area can be
enlarged. As such, a localization scheme designed for mobile sensor networks is necessary. In this paper, we propose a localization
scheme to improve the localization accuracy of previous work. In this proposed scheme, the normal nodes without location information
can estimate their ....etc

ABSTRACT
Some applications of simulation require that the model
state be advanced in simulation time faster than the
wall-clock time advances as the simulation executes.
This faster than real-time requirement is crucial, for
instance, when a simulation is used as part of a real-
time control system, working through the consequences
of contemplated control actions, in order to identify
feasible (or even optimal) decisions. This paper con-
siders the issue of faster than real-time simulation of
very large comm ....etc

Abstract
In this paper, we study the localization problem in large-scale Underwater Wireless
Sensor Networks (UWSNs). Unlike in the terrestrial positioning, the global positioning system
(GPS) can not work efficiently underwater. The limited bandwidth, the severely impaired
channel and the cost of underwater equipment all makes the localization problem very
challenging. Most current localization schemes are not well suitable for deep underwater
environment. We propose a hierarchical localization scheme to address the challenging

A metasearch engine supports unified access to multiple component search engines. To build a very large-scale metasearch engine that can access up to hundreds of thousands of component search engines, one major challenge is to incorporate large numbers of autonomous search engines in a highly effective manner. To solve this problem, we propose automatic search engine discovery, automatic search engine connection, and automatic search engine result extraction techniques. Experiments indicate that these techniques are highly effective and efficie ....etc
