Today’s kernel based protocol implementation architectures may lead to a major performance limitation in the context of local high-speed networks. In this paper, we describe an approach for hardware support of transport layer protocols. Because of the high complexity of such protocols and various environmental conditions and requirements, such architecture must be very flexible and adaptable. H...

Combustion in the cylinder of a spark ignition engine, particularly under low load conditions, is subject to cycleby-cycle variations due to factors such as mixture quality and quantity and internal exhaust gas recirculation. The major result of this phenomenon is an increase in the variability of indicated engine torque at a given engine operating point. Automotive control problems dealing wit...

The goal of this research is to provide hypermedia functionality to all information systems that interact with people. Hypermedia is a concept involving access to information, embodying the notions of context-sensitive navigation, annotation and tailored presentation. We present the architecture of a system-level hyperniedia engine, designed both to manage full hypermedia functionality for an i...

The equations of motion for the major components in an internal combustion engine are developed herein using a recursive formulation. These components include the (rigid) engine block, pistons, connecting rods, (flexible) crankshaft, balance shafts, main bearings, and engine mounts. Relative coordinates are employed that automatically satisfy all constraints and therefore lead to the minimum se...

In this paper, we propose a framework supporting dynamic interoperation between heterogeneous workflow systems and workflow-based dynamic Enterprise Application Integration (EAI). To this end, based on Subflow Task Model and Multi-Tiered Dynamic State Transition Model, four major components are defined: The workflow engine, Adapter, Service Interface Repositories (SIRs), and XML messages. Workf...

CU VOCAL is a Cantonese text-to-speech (TTS) engine. We use a syllable-based concatenative synthesis approach to generate intelligible and natural synthesized speech [1]. This paper describes several recent enhancements in CU VOCAL. First, we have augmented the syllable unit selection strategy with a positional feature. This feature specifies the relative location of a syllable in a sentence an...

OSCR, a framework for the implementation of a cognitive radio, is designed to facilitate the integration of a cognitive engine with one or more existing Software Communications Architecture (SCA) based radios. It consists of two components: a multiplexer, which acts as the cognitive engine’s point of control for each individual radio within the system, and an SCA resource within each radio, whi...

(Background) We developed in previous work a biomedical data warehouse for mining clinical reports by full text search engine. But the lack of consideration of negation and family history generate noise. (Methods) We developed an algorithm to detect the French notion of negation in medical reports and he context of family history. The semantic enrichment reflects this new semantic information. ...

Bruce Spencer and Sandy Liu are the leader and a researcher in the Internet Logic group, which specializes in reasoning systems for Internet applications. The group’s activities on the Semantic Web include (i) a Semantic Web Lab with close ties to RuleML.org, (ii) a graduate course at the University of New Brunswick on the Semantic Web Techniques, (iii) BASeWEB (Business Agents and the Semantic...

We present an approach and architecture for implementing scalable and maintainable clinical decision support at the Partners HealthCare System. The architecture integrates a business rules engine that executes declarative if-then rules stored in a rule-base referencing objects and methods in a business object model. The rules engine executes object methods by invoking services implemented on th...
