Quality-of-service routing with two concave constraints
Description :
Routing is a process of finding a network path from a source node to a destination node. A good routing protocol should find the "best path" from a source to a destination. When there are independent constraints to be considered, the "best path" is not well-defined. In our previous work, we develope...

Aggregation-based QoS routing in the internet
Description :
In this paper, we study the problem of QoS routing with two concave constraints in the Internet. We propose an efficient approach for computing the supported QoS across domains based on the aggregated intradomain topology. The time complexity of our approach is polynomial. Moreover, our approach can...

Recognition of handwritten Chinese characters by critical region analysis
Description :
The problem of recognizing offline handwritten Chinese characters has been investigated extensively. One difficulty is due to the existence of characters with very similar shapes. In this paper, we propose a "critical region analysis" technique which highlights the critical regions that distinguish ...

Recognition of handwritten Chinese characters by combining regularization, Fisher's discriminant and distorted sample generation
Description :
The problem of offline handwritten Chinese character recognition has been extensively studied by many researchers and very high recognition rates have been reported. In this paper, we propose to further boost the recognition rate by incorporating a distortion model that artificially generates a huge...

Improvement of fingerprint retrieval by a statistical classifier
Description :
The topics of fingerprint classification, indexing, and retrieval have been studied extensively in the past decades. One problem faced by researchers is that in all publicly available fingerprint databases, only a few fingerprint samples from each individual are available for training and testing, m...

Performance assessment of network protocols and parallel programming tools for distributed computing systems
Description :
Current advances in processor technology, networking technology, and software tools have made high-performance distributed computing over Local Area Networks (LANs) a promising alternative to traditional parallel and vector supercomputers. In this paper, we analyze the performance of two widely used...

Decontamination of landfill leachate by soil infiltration.
Description :
A soil column study was conducted to evaluate the efficiency of soil to attenuate pollutants in landfill leachate. It was found that more than 60% of the initial alkalinity, COD, and total nitrogen was removed after the leachate had percolated through the soil column. Lower efficiencies were observe...

A paracasting model for concurrent access to replicated internet content
Description :
In this paper, we develop a model to study how to effectively download a document from a set of replicated servers. We propose a generalized application-layer anycasting protocol, known as paracasting, to advocate concurrent access of a subset of replicated servers to cooperatively satisfy a client'...
