The Interplay of Web Aggregation and Regulation
(2003-01)The development of web technology has led to the emergence of web aggregation, a service that collects existing web data and turns them into more useful information. We review the development of both comparison and ... -
An Interpolative Analytical Cache Model with Application to Performance-Power Design Space Exploration
(2005-01)Caches are known to consume up to half of all system power in embedded processors. Co-optimizing performance and power of the cache subsystems is therefore an important step in the design of embedded systems, especially ... -
Keyword Join: Realizing Keyword Search for Information Integration
(2006-01)Information integration has been widely addressed over the last several decades. However, it is far from solved due to the complexity of resolving schema and data heterogeneities. In this paper, we propose out attempt to ... -
Keyword Join: Realizing Keyword Search in P2P-based Database Systems
(2005-01)In this paper, we present a P2P-based database sharing system that provides information sharing capabilities through keyword-based search techniques. Our system requires neither a global schema nor schema mappings between ... -
Knowledge Integration to Overcome Ontological Heterogeneity: Challenges from Financial Information Systems
(2003-01)The shift towards global networking brings with it many opportunities and challenges. In this paper, we discuss key technologies in achieving global semantic interoperability among heterogeneous information systems, including ... -
Learning object boundary detection from motion data
(2004-01)This paper describes the initial results of a project to create a self-supervised algorithm for learning object segmentation from video data. Developmental psychology and computational experience have demonstrated that the ... -
Learning object boundary detection from motion data
(2003-01)A significant barrier to applying the techniques of machine learning to the domain of object boundary detection is the need to obtain a large database of correctly labeled examples. Inspired by developmental psychology, ... -
Learning Three-Dimensional Shape Models for Sketch Recognition
(2005-01)Artifacts made by humans, such as items of furniture and houses, exhibit an enormous amount of variability in shape. In this paper, we concentrate on models of the shapes of objects that are made up of fixed collections ... -
Lower Bounds for Achieving Synchronous Early Stopping Consensus with Orderly Crash Failures
(2005-01)In this paper, we discuss the consensus problem for synchronous distributed systems with orderly crash failures. For a synchronous distributed system of n processes with up to t crash failures and f failures actually occur, ... -
Mapping Unstructured Parallelism to Series-Parallel DAGs
(2004-01)Many parallel programming languages allow programmers to describe parallelism by using constructs such as fork/join. When executed, such programs can be modeled as directed graphs, with nodes representing a computation and ... -
Matching Interest Points Using Projective Invariant Concentric Circles
(2005-01)We present a new method to perform reliable matching between different images. This method exploits a projective invariant property between concentric circles and the corresponding projected ellipses to find complete region ... -
MATLAB*G: A Grid-Based Parallel MATLAB
(2004-01)This paper describes the design and implementation of MATLAB*G, a parallel MATLAB on the ALiCE Grid. ALiCE (Adaptive and scaLable internet-based Computing Engine), developed at NUS, is a lightweight grid-computing middleware. ... -
MATLAB*P 2.0: A unified parallel MATLAB
(2003-01)MATLAB is one of the most widely used mathematical computing environments in technical computing. It is an interactive environment that provides high performance computational routines and an easy-to-use, C-like scripting ... -
A Media Player for Use in Distance Education
(2004-01)We have developed a media player for use in distance education. The player can incorporate several time-indexed sources, including video, audio, PowerPoint, and text index. We have converted all the SMA 5503 Introduction ... -
Memory Hierarchy Hardware-Software Co-design in Embedded Systems
(2005-01)The memory hierarchy is the main bottleneck in modern computer systems as the gap between the speed of the processor and the memory continues to grow larger. The situation in embedded systems is even worse. The memory ... -
Memory Usage Inference for Object-Oriented Programs
(2005-01)We present a type-based approach to statically derive symbolic closed-form formulae that characterize the bounds of heap memory usages of programs written in object-oriented languages. Given a program with size and alias ... -
Mobile P2Ping: A Super-Peer based Structured P2P System Using a Fleet of City Buses
(2005-01)Recently, researchers have introduced the notion of super-peers to improve signaling efficiency as well as lookup performance of peer-to-peer (P2P) systems. In a separate development, recent works on applications of mobile ... -
Modeling Information Flow in Face-to-Face Meetings while Protecting Privacy
(2006-01)Social networks have been used to understand how information flows through an organization as well as identifying individuals that appear to have control over this information flow. Such individuals are identified as being ... -
MPEG-2 in a Stream Programming Language
(2006-01)Image and video codecs are prevalent in multimedia applications, ranging from embedded systems, to desktop computers, to high-end servers such as HDTV editing consoles. It is not uncommon however for developers create (from ... -
A New Constructive Method for the One-Letter Context-Free Grammars
(2004-01)Constructive methods for obtaining the regular grammar counterparts for some sub-classes of the context free grammars (cfg) have been investigated by many researchers. An important class of grammars for which this is always ...
