Texto completoWireless technology is a key enabler of the promises of Industry 4.0 (Smart Manufacturing). As such, wireless technology will be adopted as a principal mode of communication within the factory beginning with the factory enterprise and eventually being adopted for use within the factory workcell. Factory workcell communication has particular requirements on latency, reliability, scale, and security that must first be met by the wireless communication technology used. Wireless is considered a non-ideal form of communication in that when compared to its wired counterparts, it is considered less reliable (lossy) and less secure. These possible impairments lead to delay and loss of data in industrial automation system where determinism, security, and safety is considered paramount. This thesis investigates the wireless requirements of the factory workcell and applicability of existing wireless technology, it presents a modeling approach to discovery of architecture and data flows using SysML, it provides a method for the use of graph databases to the organization and analysis of performance data collected from a testbed environment, and finally provides an approach to using machine learning in the evaluation of cyberphysical system performance

Texto completoMotor learning as a recovery mechanism is assumed to be a framework that drived and guided physical therapy and now since the advent of robotics doing the same to the rehabilitation devices. The rehabilitation process presents the intersection of many different interconnected facets that co-interact to produce recovered movements. The use of the technology introduces many benefits while contributing to the complexity of the phenomena at hand. We interest our research to the passive exosquelette training of the upper limb. We propose an adaptive intra patient assessment scale that is capable of detecting intra-patient performance changes during robotic training. Motor learning, the process of our brain's acquiring newer motor skills or relearning those he lost due to neurological or traumatic incident is our portal to investigating this phenomenon. The interaction of the system that is composed of the device, the incentive in form of exercise games and the patients with all its level of existence, physiological, psycho-logical, and cognitive is the system of study. The components present heterogeneous qualities and dynamically driven changes. The system output in the form of the trajectories executed is our gauging instrument to investigate the interactions within the system. We formulate the trajectory model as a Markov Chain and use the Kalman Filter to estimate the smoothed states. While dynamics are variant in time we model the assumptions about the movement into a dynamical formulation and estimate its parameters from data. To account for the time variability we introduce parallel noise source to the dynamics and estimate it using an Expectation-Maximization algorithm. The temporal nature being only a single facet of the kinematic phenomena, we assume a variable temporal alignment and estimate it using Expectation-Maximization iteration to increase the likelyhood of the estimated model compared to the observed trajectories. Once learned the model dependent and extracted parameters are used to compare between differences in performance. The properties of the clinical assessment tools are investigated and results are formulated to answer the commonly reported needs. Stemming from the same fundamentals of motor learning, we aimed to define a new visual assessment instrument that is intended to fulfill the need of patient-first easily communicated feedback form. We present and assess clinical properties of the tools while providing validating results on clinical data attesting the longitudinal sensitivity of the tool. The underlying assumption of the visualization was then assessed using an objective measure of maximum probability value derived using a probabilistic model of the trajectories and expected on a highly likely trajectory model learned using a Kernel-Near-Neighbors Regressor

Texto completoWe describe models and algorithms designed to produce efficient and physically consistent dynamic simulations. These models and algorithms have been implemented within the RobotΦ system\cite(RAP95) which can potentially be configured for a large variety of interven\-tion-style tasks such as dextrous manipulations with a robot hand; manipulation of non-rigid objects; tele-programming of the motions of an all-terrain vehicle; and some robot assisted surgery tasks (e. G. Positioning of an artificial ligament in knee surgery). The approach uses a novel physically based modeling technique to produce dynamic simulations which are both efficient and consistent according to the laws of the Physics. The main advances over previous works in Robotics and Computer Graphics fields are twofold: the development of a unique framework for simultaneously processing motions, deformations, and physical interactions; and the incorporation of appropriate models and algorithms for obtaining efficient processing times while insuring consistent physical behaviors

Texto completoThis work falls within the field of image synthesis and computer animation by physical modelling. The modelling and visualization of physical objets consists in a work on shape, motion and image. The more a given reference object is deformable and the more the relation between these three phenomena may grow complex. We study this relation and determine in which conditions the behaviour (shape, motion and image) of an object may be represented by several models which are autonomous (multi-scale modelling) and discoupled (clothing « habillage »). In particular, we study highly deformable objects. A shape modeler for this type of object must verify a certain number of properties. We present a shape model verifying these conditions. We study its dynamic behaviour and present the resulting images
