Finite Memory Observers for linear time-varying systems: Theory and diagnosis applications     

Guillaume Graton  Frédéric Kratz  Jacques Fantini 《Journal of The Franklin Institute》2014

Fault detection and diagnosis are important issues in process engineering. Hence, a considerable interest exists in this field now from industrial practitioners as well as academic researchers, as opposed to 30 years ago. The literature on process fault diagnosis, ranging from analytical methods to artificial intelligence and statistical approaches, is largely widespread. In this paper, the modeling of the real process is known, and the state-space representation is used. The properties of the Finite Memory Observer (FMO) are studied from a global point of view for the class of linear time-varying (LTV) systems with stochastic noises. The FMO performances are framed by the study of their properties, and that of their influences on diagnosis results. Fundamentally, the generation of residuals is an essential procedure in diagnosis. So, the determination of the optimal window length of the observer is resolved, and the generation of residuals for diagnosis completed. In the first part, the design of the observer and the residual generation are shown. The second part is devoted to the study of the sensitivity and robustness of the observer and of residuals generated from the observer.  相似文献   

Evaluating innovative processes in french firms: Methodological proposition for firm innovation capacity evaluation     

Vincent Boly  Laure Morel  N’Doli Guillaume Assielou  Mauricio Camargo 《Research Policy》2014

Measuring innovation processes is a major concern for academics and firm managers. This study proposes an innovation capacity (IC) measure framework based on a set of 15 innovation management practices. Every practice is subdivided into multiple criteria which are directly observable phenomena or facts. The statistical method of value test and a multi-criteria approach are adopted to propose a typology of four groups of innovative firms (proactive, preactive, reactive, passive). The features observed on these groups of firms allow the determination of the firms’ innovation capacity and are useful for providing recommendations and practical actions for them, with a view to reinforcing it. Data from a sample group of 39 small and medium sized enterprises (SMEs) in the manufacturing industry in Lorraine, France were collected via a field survey and were fed into the model to determine the innovation capacity of the companies.  相似文献   

Anticipatory postural adjustments during cutting manoeuvres in football and their consequences for knee injury risk     

Guillaume Mornieux  Dominic Gehring  Patrick Fürst  Albert Gollhofer 《Journal of sports sciences》2014,32(13):1255-1262

Abstract

Anticipatory postural adjustments (APAs), i.e. preparatory positioning of the head, the trunk and the foot, are essential to initiate cutting manoeuvres during football games. The aim of the present study was to determine how APA strategies during cutting manoeuvres are influenced by a reduction of the time available to prepare the movement.

Thirteen football players performed different cutting tasks, with directions of cutting either known prior to the task or indicated by a light signal occurring 850, 600 or 500 ms before ground contact.

With less time available to prepare the cutting manoeuvre, the head was less orientated towards the cutting direction (P = 0.033) and the trunk was even more rotated in the opposite direction (P = 0.002), while the foot placement was not significantly influenced. Moreover, the induced higher lateral trunk flexion correlated with the increased knee abduction moment (r = 0.41; P = 0.009).

Increasing lateral trunk flexion is the main strategy used to successfully perform a cutting manoeuvre when less time is available to prepare the movement. However, higher lateral trunk flexion was associated with an increased knee abduction moment and therefore an increased knee injury risk. Reducing lateral trunk flexion during cutting manoeuvres should be part of training programs seeking the optimisation of APAs.  相似文献   

The effect of context on student engagement in engineering     

Eann A. Patterson  Patricia B. Campbell  Ilene Busch-Vishniac  Darrell W. Guillaume 《European Journal of Engineering Education》2011,36(3):211-224

The self-belief, motivation, tendency to procrastinate and learning styles of engineering students are discussed. It is proposed that engineering has developed an idiom and a learning approach that favours the dominant client, i.e. men, while simultaneously undermining the self-efficacy and motivation of women. Thematic coherence and teaching within a context that is familiar to students have been shown previously to be effective approaches for engaging students and are extended here to utilise the common experiences of all students to initiate the learning cycle. These approaches are combined with a template for teaching that uses the 5Es (Engage, Explore, Explain, Elaborate and Evaluate) in order to render the fundamentals of engineering more accessible to all students. This methodology can be introduced by individual instructors, who will be rewarded by students who are more engaged, more motivated and more likely to give a higher rating to the instructor and the course.  相似文献   

Client value models provide a framework for rational library planning (or, phrasing the answer in the form of a question)     

Van Moorsel G 《Medical reference services quarterly》2005,24(2):25-40

Libraries often do not know how clients value their product/ service offerings. Yet at a time when the mounting costs for library support are increasingly difficult to justify to the parent institution, the library's ability to gauge the value of its offerings to clients has never been more critical. Client Value Models (CVMs) establish a common definition of value elements-or a "value vocabulary"-for libraries and their clients, thereby providing a basis upon which to make rational planning decisions regarding product/service acquisition and development. The CVM concept is borrowed from business and industry, but its application has a natural fit in libraries. This article offers a theoretical consideration and practical illustration of CVM application in libraries.  相似文献   

Self-control of task difficulty during training enhances motor learning of a complex coincidence-anticipation task     

Andrieux M  Danna J  Thon B 《Research quarterly for exercise and sport》2012,83(1):27-35

The aim of the present work was to analyze the influence of self-controlled task difficulty on motor learning. Participants had to intercept three targets falling at different velocities by displacing a stylus above a digitizer Task difficulty corresponded to racquet width. Half the participants (self-control condition) could choose the racquet width at the beginning of each trial. Each was paired with a participant from the yoked group. The self-control condition resulted in better performances and accuracy during immediate and delayed retention tests. These results confirm the advantage of a self-control condition on motor learning. They are discussed with reference to the challenge point hypothesis (Guadagnoli & Lee, 2004).  相似文献   

A hybrid approach to managing job offers and candidates     

Rémy Kessler  Nicolas Béchet  Mathieu Roche  Juan-Manuel Torres-Moreno  Marc El-Bèze 《Information processing & management》2012

The evolution of the job market has resulted in traditional methods of recruitment becoming insufficient. As it is now necessary to handle volumes of information (mostly in the form of free text) that are impossible to process manually, an analysis and assisted categorization are essential to address this issue. In this paper, we present a combination of the E-Gen and Cortex systems. E-Gen aims to perform analysis and categorization of job offers together with the responses given by the candidates. E-Gen system strategy is based on vectorial and probabilistic models to solve the problem of profiling applications according to a specific job offer. Cortex is a statistical automatic summarization system. In this work, E-Gen uses Cortex as a powerful filter to eliminate irrelevant information contained in candidate answers. Our main objective is to develop a system to assist a recruitment consultant and the results obtained by the proposed combination surpass those of E-Gen in standalone mode on this task.  相似文献   

Qualitative differences in the exploration of upright and upside-down faces in four-month-old infants: an eye-movement study     

Gallay M  Baudouin JY  Durand K  Lemoine C  Lécuyer R 《Child development》2006,77(4):984-996

Four-month-old infants were habituated with an upright or an upside-down face. Eye-movement recordings showed that the upright and upside-down faces were not explored the same way. Infants spent more time exploring internal features, mainly in the region of the nose and mouth, when the face was upright. They also alternated as frequently between the face's internal features (eyes vs. nose/mouth) as between external and internal features. When the face was upside down, the infants spent half of their time exploring external features, and preferentially alternated between external features and internal features. The main effect of inversion was a decrease of the looking time to the nose/mouth region and of the number of shifts between the eye region and the nose/mouth region.  相似文献
