Optimal Dynamic Route Guidance: A Model Predictive Approach Using the Macroscopic Fundamental Diagram

Since centralized control of urban networks with detailed modeling approaches is computationally complex and inefficient, hierarchical decentralized methods based on aggregate models are of great importance. In this paper, we use an aggregate modeling appr ...

Hierarchy-oriented modeling of enterprise architecture using reference-model of open distributed processing

Alain Wegmann, Lam Son Lê

Modeling Enterprise Architecture (EA) requires the representation of multiple views for an enterprise. This could be done by a team of stakeholders that essentially have different backgrounds. One way to do this is to structure the model into hierarchical ...

Probabilistic Lexical Modeling and Grapheme-based Automatic Speech Recognition

Ramya Rasipuram

Standard hidden Markov model (HMM) based automatic speech recognition (ASR) systems use phonemes as subword units. Thus, development of ASR system for a new language or domain depends upon the availability of a phoneme lexicon in the target language. In th ...

The Idiap Speaker Recognition Evaluation System at NIST SRE 2012

Sébastien Marcel, Laurent El Shafey

In this paper, we present the Idiap Research Institute submission to the 2012 NIST Speaker Recognition Evaluation. Our system is based on the Inter-Session Variability (ISV) modelling technique. The implementation of the system relies on Bob, a free signal ...

Semantic Activity Classification Using Locomotive Signatures from Mobile Phones

Karl Aberer, Zhixian Yan, Dipanjan Chakraborty, Ho Young Jeung

We explore the use of mobile phone-generated sensor feeds to determine the high-level (i.e., at the semantic level), indoor, lifestyle activities of individuals, such as cooking & dining at home and working & having lunch at the work- place. We propose and ...

SAMMPLE: Detecting Semantic Indoor Activities in Practical Settings using Locomotive Signatures

Karl Aberer, Zhixian Yan, Dipanjan Chakraborty, Ho Young Jeung

We analyze mobile phone-generated sensor feeds to de- termine the high-level (i.e., at the semantic level), indoor, lifestyle activities of individuals, such as cooking/dining at home and working/having-lunch at the workplace. We pro- pose and evaluate a 2 ...

Modelling competence-based virtual organisations using the unified enterprise competence modelling language

Naoufel Cheikhrouhou

Virtual organisations are non-conventional structures aiming at sharing the same goals, developing common practices or creating wealth in a collaborative manner. Accordingly, competence issues are important topics to be addressed in order to ensure coheren ...

Exploiting the fundamental diagram of urban networks for feedback-based gating

Anastasios Kouvelas, Mehdi Keyvan Ekbatani

Traffic signal control for urban road networks has been an area of intensive research efforts for several decades, and various algorithms and tools have been developed and implemented to increase the network traffic flow efficiency. Despite the continuous ...

A coupled observation - Modeling approach for studying activation kinetics from measurements of CCN activity

Athanasios Nenes

This paper presents an approach to study droplet activation kinetics from measurements of CCN activity by the Continuous Flow Streamwise Thermal Gradient CCN Chamber (CFSTGC) and a comprehensive model of the instrument and droplet growth. The model, which ...

Generalization of the Concept of Equivalent Thickness and Capacitance to Multigate MOSFETs Modeling

Jean-Michel Sallese, Christophe Lallement

In this letter, we propose to introduce the notion of equivalent capacitance and to generalize the so-called equivalent-thickness concept to model arbitrary shapes of lightly doped nonplanar multigate MOSFETs, without the need to introduce any unphysical p ...
