Modeling Workplace Evacuation Behaviors Using Intelligent Agents

A major challenge in artificial intelligence has been the development of autonomous agents (AAs) capable of displaying believable behaviors. To achieve such objective, the underlying architectures of these intelligent systems have been designed to incorporate Learning Classifier System that provides an adaptation naturally with the environment. It is expected that through the interaction of this type of components, AAs can implement more intelligent and believable behavior. Although the literature reports several computational models of behaviors, attention, and emotions developed to be included in cognitive agent architectures, these have been implemented as separated processes, disregarding essential interactions between these behaviors whose modeling and computational implementation may increase the believability of actions developed by AAs. In this paper, we propose an evolutive computational model. This model is designed to provide AAs with adequate mechanisms to attend and react to conditions and changes in the environment.isa-CTEE

Facial Geometry Identification through Fuzzy Patterns with RGBD Sensor

Automatic human facial recognition is an important and complicated task; it is necessary to design algorithms capable of recognizing the constant patterns in the face and to use computing resources efficiently. In this paper we present a novel algorithm to recognize the human face in real time; the systems input is the depth and color data from the Microsoft KinectTM device. The algorithm recognizes patterns/shapes on the point cloud topography. The template of the face is based in facial geometry; the forensic theory classifies the human face with respect to constant patterns: cephalometric points, lines, and areas of the face. The topography, relative position, and symmetry are directly related to the craniometric points. The similarity between a point cloud cluster and a pattern description is measured by a fuzzy pattern theory algorithm. The face identification is composed by two phases: the first phase calculates the face pattern hypothesis of the facial points, configures each point shape, the related location in the areas, and lines of the face. Then, in the second phase, the algorithm performs a search on these face point configurations

Autonomous Motion Planning for Avatar Limbs

In this work, a new algorithm for autonomous avatar motion is presented. The new algorithm is based in the Rapidly-exploring Random Tree (RRT) and an appropriate ontology. It uses a novel approach for calculating the motion sequence planning for the different avatar limbs: legs or arms. First, the algorithm uses the information stored in the ontology concerning the avatar structure and the Degrees Of Freedom (DOFs) to obtain the basic actions for motion planning. Second, this information is used to perform the growth process in the RRT algorithm. Then, all this information is used to produce planning. The plans are generated by a random search for possible motions that respect the structural restrictions of the avatar on kinesiology studies. To avoid a big configuration space search, exploration, exploitation, and hill climbing are used in order to obtain motion plans

Implementación numérica del modelo de elemento finito para cálculo del comportamiento mecánico de las diferentes fases del cemento portland mexicano

El concreto es un material heterogéneo, una mezcla de compuestos que en una magnitud de milésimas de centímetro puede ser diferenciado en tres diferentes fases que contienen mortero, agregados e interfases (Taylor, 1997). A esta escala se pueden llevar a cabo estudios de tipo mesoscópico, útiles para conocer el comportamiento macroscópico de una estructura hecha con concreto (Xiao 2007). Estos análisis son útiles para conocer el comportamiento de determinada mezcla y así saber su comportamiento mecánico o termodinámico. La manera de obtener un modelo que permita dicho estudio se logra a través de la generación de una estructura suficientemente cercana a la real, a través de distribuciones de probabilidad que ubiquen a los componentes, como se muestra en la Figura 1 (Wang et al., 1999). Una vez alcanzada una estructura considerada satisfactoria, se utiliza una malla formada por elementos finitos a través de la cual pueda modelarse un conjunto de características mecánicas o aún termodinámicas sobre este material (Tang et al, 2008).Este reporte cubre las actividades relacionadas con el subproyecto Implementación numérica del modelo de elemento finito para cálculo del comportamiento mecánico de las diferentes fases del cemento portland mexicano, segunda etapa, el cual tiene como objetivo general la programación del modelo de elemento finito para la simulación del comportamiento mecánico de las fases presentes en los productos de hidratación del cemento Portland Mexicano y arenas, es decir modela por medio del elemento finito la interacción mecánica entre al menos dos materiales diferentes

Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).

Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Etude et proposition d’un système comportemental autonome anticipatif

La génération de comportements autonomes est directement associée à la perception que l'agent a de son environnement et à sa capacité d'adaptation. Dans les systèmes dynamiques, la qualité d'adaptation sera un critère plus déterminant que pour les environnements statiques. La robustesse de ces systèmes sera évaluée par rapport à leurs capacités à détecter un changement dans l'environnement et à fournir une réponse appropriée. Différentes approches sont proposées pour l'émergence de comportements : définition d'un modèle décisionnel, stimulus / réponse, script de comportement, environnement prédéfinis et automates. Ces modèles restent relativement simples mais leur problème est qu'ils ne prennent pas en compte l'aspect temporel qui est primordial dans la prise de décision. Nous cherchons un modèle qui prenne en compte le paramètre temps. Nous nous sommes intéressés principalement aux systèmes de classeur pour leur originalité dans leur manière de représenter l'environnement. Notre objectif est de construire un système comportemental ayant non seulement des capacités d'adaptation et d'évolution mais également la capacité d'anticipation.The generation of autonomous behaviours is directly associated to perception that the agent has from the environment and the capacity of adaptation. In the dynamic systems, the quality of adaptation will be a criterion more determinant that for the static environments. The robustness of thes systems will be evaluated compared to their capacities to detect the changes in the environment and to provide a suitable answer. Various approaches are proposed for the emergence of behaviors : definition of a decisional model, stimulus/answer, and scripts of behaviours. These models remain relatively simple but their problem is that they not take into account the temporal aspect which is of primary importance in the decision-making. We seek a model which takes into account the parameter time. We were interested mainly in the systems of sorter for their originality in their manner of representing the environment. Our objective is to build a behavioural system having not only capacities of adaptation and evolution but also the capacity of anticipation
