Breaking the walls: Scene partitioning and portal creation
(IEEE Computer Society, 2003)In this paper, we revisit the cells-and-portals visibility methods, originally developed for the special case of architectural interiors. We define an effectiveness measure for a cells-and-portals partitioning, and introduce ...

Efficient cells-and-portals partitioning
(2006)In this paper we revisit the cells-and-portals visibility methods, originally developed for the special case of architectural interiors. We define an effectiveness measure for a cells-and-portals partition, and introduce ...

A congestion control algorithm for max-min resource allocation and bounded queue sizes
(2004)This paper deals with the congestion control problem in computer networks which is viewed as a resource allocation problem constrained by the additional requirement that the queue sizes need to be bounded. We propose a ...

Article
Global asymptotic stability of max-min congestion control schemes
(2017)A number of congestion control schemes which adopt the max-min fairness criterion and do not require maintenance of per flow states within the network have been proposed in the literature. The establishment of global ...

On a hybrid model for max-min congestion controllers
(2004)In this paper we address the congestion control problem in computer networks offering a single class of best effort service. The problem is viewed as a resource allocation problem. The objective is to distribute the available ...

Fitting behaviors to pedestrian simulations
(2009)In this paper we present a data-driven approach for fitting behaviors to simulated pedestrian crowds. Our method annotates agent trajectories, generated by any crowd simulator, with action-tags. The aggregate effect of ...

Data driven evaluation of crowds
(2009)There are various techniques for simulating crowds, however, in most cases the quality of the simulation is measured by examining its "look-and- feel". Even if the aggregate movement of the crowd looks natural from afar, ...

Emotional web-based design: the concepts of emotional experience and emotional expression
(2011)For many years people have been trying to measure differences between individuals. Over the course of time, a combination of developments in statistical know-how and the evolution of thought within psychology enabled the ...

Coordinating web services using channel based communication
(2004)In this work we investigate the use of a new concept in component communication during the coordination of Web Services, expressed by the channel based coordinating communication system called Reo. The role of Reo is to ...

Implementing affect parameters in personalized web-based design
(2009)Researchers used to believe that emotional processes are beyond the scope of a scientific study. Recent advances in cognitive science and artificial intelligence, however, suggest that there is nothing mystical about ...

The role of affect in personalized learning
(2009)Research on modelling affect and on interfaces adaptation based on affective factors has matured considerably over the past several years. Emotions are considered to play a central role in guiding and regulating learning, ...

Frequency-domain characterization of Singular Spectrum Analysis eigenvectors
(Institute of Electrical and Electronics Engineers Inc., 2017)Singular Spectrum Analysis (SSA) is a nonparametric approach used to decompose a time series into meaningful components, related to trends, oscillations and noise. SSA can be seen as a spectral decomposition, where each ...

The role of emotion in the design of personlized educational systems
(2008)Research on modelling affect and on interfaces adaptation based on affective factors has matured considerably over the past several years, so that designers of educational products are now considering the inclusion of ...

Process algebraic modelling and analysis of power-aware real-time systems
(2002)A unified formal framework for designing and reasoning about power-constrained, real-time systems is described. The framework is based on process algebra, a formalism that has been developed to describe and analyse ...

Personality and emotion as determinants of the learning experience: How affective behavior interacts with various components of the learning process
(2013)The aim of the present study is to develop a model that grasps the complexity of the concepts of personality and affect in a web-based learning environment. Furthermore, it presents the implications that these theoretical ...
