This paper presents the ability of hybrid zero dynamics (HZD) feedback control method to reproduce human like movements for walking push recovery of an under-actuated 3D biped model. The balance recovery controller is implemented on a three-dimensional under-actuated bipedal model subjected to a push disturbance. The biped robot model is considered as a hybrid system with eight degrees of freed...

A node-exhaustion-safe intrusion-tolerant distributed system is a system that assuredly does not suffer more than the assumed number of node failures. In a recent work, we showed that it is not possible to build any type of nodeexhaustion-safe distributed f intrusion-tolerant system under the asynchronous model. Some years ago, an intuition about this problem motivated the research around proac...

This paper describes a project that added temporal information and constraints to SRI International’s SIPE–2 hierarchical, nonlinear planning system. The goal was to incorporate the ability to represent temporal relationships between actions within a plan, and time window constraints on individual actions, and to maintain these constraints during the planning process. The extensions described i...

In composing and using services, user’s requirements are subject to uncertainty and changes. It can be difficult for users to maintain an overview of all available services and to make good choices among them. This paper proposes an approach to proactively recommending suitable services to users. Our major contribution is to have devised a novel user-interest model to describe user’s interests ...

Natural gas produced at high pressure (50-70 bar) is the only industrial source of helium (He). A membrane separation process may offer a more efficient production system with smaller footprint and lower operational cost than conventional cryogenic system. Inorganic membranes with high mechanical strength are known to exhibit good stability at high pressure. In this work, two inorganic membrane...

This paper presents a study on the automatic characterization of negative emotion in a context of voice service, based on the calculation of acoustic parameters from the speech signal and a LDA classifier. The novelty of this study lies in the application-specific constraints (type of dialog, ASR connection) imposed on the emotion characterization system, and in the solutions proposed to this p...
