Pyramid multi-level features for facial demographic estimation

Salah Eddine Bekhouche, Abdelkrim Ouafi, Fadi Dornaika, Abdelmalik Taleb-Ahmed, Abdenour Hadid

We present a novel learning system for human demographic estimation in which the ethnicity, gender and age attributes are estimated from facial images. The proposed approach consists of the following three main stages: 1) face alignment and preprocessing; 2) constructing a Pyramid Multi-Level face…

Variable neighborhood search: basics and variants

Pierre Hansen, Nenad Mladenovic, Raca Todosijević, Said Hanafi

Variable neighborhood search (VNS) is a framework for building heuristics, based upon systematic changes of neighborhoods both in a descent phase, to find a local minimum, and in a perturbation phase to escape from the corresponding valley. In this paper, we present some of VNS basic schemes as…

The use of task modeling in interactive system specification

Taisa Guidini Gonçalves, Káthia Marçal de Oliveira, Christophe Kolski

Task modeling is undoubtedly a key step for task analysis during the development of iterative systems since it helps not only in the understanding of what users want but also in how to design for them. As a consequence, it should be considered as indispensable while specifying the requirements of…

A hybrid reinforced learning system to estimate resilience indicators

Simon Enjalbert, Frédéric Vanderhaegen

This paper describes a learning system based on resilience indicators. It proposes a hybrid learning system to estimate Human–Machine System performance when facing unprecedented situations. Collected data from various criteria are compared with data estimated using the local and the global…

Gender roles, sex and the expression of driving anger

Mark Sullman, Julie Paxion, Amanda Stephens

The present study investigated the validity of the 25-item Driving Anger Expression Inventory (DAX) as well as the role of sex and gender-roles in relation to the expression of driving anger in a sample of 378 French drivers (males = 38%, M = 32.9 years old). Confirmatory Factor Analysis supported…

The effect of Fampridine (4-aminopyridine) in physical activity during weekdays and weekends in persons with multiple sclerosis

Yoshimasa Sagawa Júnior, Eric Watelain, Thierry Moulin, Pierre Decavel

Objective Fampridine (4-aminopyridine) improves walking in persons with multiple sclerosis (PwMS) in a standardized context. However, little is known about its impact on PwMS's physical activity in a real context. Indeed, the International Classification of Functioning Disability and Health…

Designing intelligent manufacturing systems through Human-Machine Cooperation principles: A human-centered approach

Marie-Pierre Pacaux-Lemoine, Damien Trentesaux, Gabriel Zambrano Rey, Patrick Millot

Since the start of industrialization, machine capabilities have increased in such a way that human control of processes has evolved from simple (with mechanization) to cognitive (with computerization), and even emotional (with semi/full automation). The processes have also evolved from simple to…

Quality characteristics and measures for human–computer interaction evaluation in ubiquitous systems

Rainara Maia Carvalho, Rossana M.C. Andrade, Káthia Marçal de Oliveira, Ismayle S. Santos, Carla Ilane Moreira Bezerra

The advent of ubiquitous systems places even more focus on users, since these systems must support their daily activities in such a transparent way that does not disturb them. Thus, much more attention should be provided to human–computer interaction (HCI) and, as a consequence, to its quality.…

Gain-scheduled H ∞ admissibilisation of LPV discrete-time systems with LPV singular descriptor

Antonio Gonzalez Sorribes, Víctor Estrada Manzo, Thierry-Marie Guerra

This paper deals with the admissibilisation with guaranteed H∞ performance of linear parameter-varying (LPV) discrete-time singular systems under gain-scheduled (GS) state-feedback control. In particular, we focus on systems with descriptor matrix of LPV form and unknown/unmeasurable disturbance…

Pollux: a dynamic hybrid control architecture for flexible job shop systems

José-Fernando Jimenez Gordillo, Abdelghani Bekrar, Gabriel Zambrano Rey, Damien Trentesaux, Paulo Leitão

Nowadays, manufacturing control systems can respond more effectively to exigent market requirements and real-time demands. Indeed, they take advantage of changing their structural and behavioural arrangements to tailor the control solution from a diverse set of feasible configurations. However, the…
