Vidéosurveillance pour appartements intelligents : application à la détection de prise de médicaments

L'objectif de cette these est de proposer une approche hierarchique pour la reconnaissance de la prise de medicaments chez les personnes âgees. En effet, l'activite globale de la prise de medicaments se compose de plusieurs activites a differents niveaux de complexite.La reconnaissance est donc faite de bas en haut, de l'activite elementaire a l'activite simple et ensuite a l'activite complexe. De plus, un modele simple de calibration, utilisant une camera stereo, est propose pour estimer la profondeur des objets, et ainsi mieux traiter l'occultation des objets. Par consequence, la reconnaissance de la prise de medicaments est plus precise.Premierement, la methode de soustraction du fond est utilisee pour detecter les objets mobiles, dans un environnement interieur. La segmentation des regions de peau, et des flacons se fait ensuite en utilisant l'information de couleur par seuillage.Deuxiemement, en observant que le deplacement des regions de peau dans deux trames consecutives est petit, nous utilisons la distance minimale de deplacement pour suivre les regions de peau. Les regions des mains sont detectees en exploitant l'intensite de contours.Nous detectons la bouche par la methode AdaBoost et le suivi de bouche se fait en utilisant le filtre de Kalman et le ratio des couleurs R/G. Le filtre de Kalman est aussi utilise pour le traitement d'occultation entre les regions d'interet main-visage, main-main.Finalement, pour la reconnaissance de la prise de medicaments, une approche hierarchique est proposee, en commencant par les activites elementaires. Sur la base du chevauchement entre les regions d'interet, nous detectons les activites elementaires. En exploitant la sequence des activites elementaires, nous detectons les activites simples, celles-ci sont en suite utilisees pour reconnaitre des activites complexes, correspondant a la prise de medicaments. La profondeur des objets occultes est estimee afin de verifier l'etat de contact entre ces objets, et reconnaitre plus precisement les activites.L'experience montre que notre approche est plus robuste et souple que les travaux precedents sur le sujet. Elle permet de reconnaitre des scenarios differents de prise de medicaments et peut etre applique pour reconnaitre d'autres activites complexes en general.
When and Why Your Code Starts to Smell Bad (and Whether the Smells Go Away)

Technical debt is a metaphor introduced by Cunningham to indicate “not quite right code which we postpone making it right”. One noticeable symptom of technical debt is represented by code smells, defined as symptoms of poor design and implementation choices. Previous studies showed the negative impact of code smells on the comprehensibility and maintainability of code. While the repercussions of smells on code quality have been empirically assessed, there is still only anecdotal evidence on when and why bad smells are introduced, what is their survivability, and how they are removed by developers. To empirically corroborate such anecdotal evidence, we conducted a large empirical study over the change history of 200 open source projects. This study required the development of a strategy to identify smell-introducing commits, the mining of over half a million of commits, and the manual analysis and classification of over 10K of them. Our findings mostly contradict common wisdom, showing that most of the smell instances are introduced when an artifact is created and not as a result of its evolution. At the same time, 80 percent of smells survive in the system. Also, among the 20 percent of removed instances, only 9 percent are removed as a direct consequence of refactoring operations.
Proceedings of the 2008 ACM SIGGRAPH/Eurographics Symposium on Computer Animation

The ACM SIGGRAPH/Eurographics Symposium on Computer Animation (SCA) is the leading meeting devoted exclusively to computer animation. The symposium attracts high quality papers and provides an opportunity for researchers in the area of computer animation to meet, share ideas and discuss emerging directions in the field. This year the eighth SCA was held in historic Dublin, Ireland, with special accommodations at Trinity College. These proceedings contain 24 papers from 60 submissions. The exceptional quality of the submitted papers made the final selection difficult. Each paper was typically reviewed by at least 4 members of the international program committee (IPC). The acceptance decisions involved sometimes lengthy online discussions among the IPC members. Similar to previous years, the final program includes papers on a variety of topics, including fluids, deformable objects, behavior modeling, real-time simulation, and motion capture and planning. This year the proceedings is in full color. The symposium continues to highlight promising works in progress with a poster and demo sessions. Our program included posters and demos which were presented in a special reception. Some of the posters were submitted papers that were not selected by the papers program, but encouraged to appear as posters. Additional posters were selected through a separate poster-review process.
APPLICATION OF MARKOV DECISION PROCESS TO LEVEL-OF-SERVICE-BASED MAINTENANCE SYSTEMS

Systems based on level of service (LOS) currently implemented to manage highway maintenance use extensive subjective data. Collection of these data is tedious and expensive and the inherent uncertainties in the data render the results imprecise. A modified method using the Markov decision process (MDP), which overcomes most of the drawbacks of the LOS-based systems, is described. The adoption of the MDP is consistent with progressive evolution in the field of highway maintenance management. It introduces measures of performance benefits that are less subjective than those used in the NCHRP LOS model, which rely on attributes and utility functions. The modified model uses three types of key input data: transition probabilities, costs, and relative-importance weights. The transition probabilities are computed analytically using sample deterioration models and quality standards. An approach is described for computing the cost of each alternative from historical data. An analytic approach is also described for computing relative-importance weights using simple ranking of and comparison scores for the highway elements. This method was tested with 58 highway elements in 12 strata and 3 levels of service each. The resulting problem, which had 2,088 variables and 697 constraints, required less than 15 min on an IBM PC using an off-the-shelf linear programming package. The results of the test were consistent with the input data and demonstrated that the objectives set for the method were being met. Although the method was tested with mostly roadside elements, it can generally be used with any LOS-based system.

Comportement asymptotique d'un corps élastique dont une surface présente de petites zones de collage

We consider an elastic body, a surface of which is partially sticked to a fixed plane. The sticked region have a diameter e and the distance between two neighbouring zones is η. The asymptotically critical size is e∼η 2 . In this case the limit behaviour of the body is described by a boundary condition which is intermediate between the perfect sticking and unsticking On considere un corps elastique dont une surface est partiellement collee a un plan fixe. Les zones de collage sont de diametre e et la distance entre deux zones de collage contigues est η. La dimension asymptotique critique est e∼η 2 . Dans ce cas, le comportement limite du corps est decrit par une condition aux limites intermediaires entre le collage parfait et le decollement total
Dynamic Updating and Management of Virtual Resource Database in Grids Using Mobile Agents

Summary Grid Computing Element (CE) is a distributed heterogeneous system of computational data and informational resources. The goal of any Grid CE is to create an integrated virtual system of resources available to the users. The nature of resource utilization is unpredictable in such computational resource rich Grid CE. So continuous and dynamic updating of the utilization of the resources in the grid clusters becomes mandatory. Virtual database decreases the information/query processing, which is a bottleneck in Centralized Monitoring mechanism. In this paper, the authors propose a Mobile-Agent based mechanism for the dynamic resource monitoring in the Grid CE. The process involves the creation and maintenance of a Virtual Resource Database for every Resource Consumer group.
A Survey of State-of-the-Art Methods on Question Classification

The task of question classification (QC) is to predict the entity type of a question which is written in natural language. This is done by classifying the question to a category from a set of predefined categories. Question classification is an important component of question answering systems and it attracted a notable amount of research since the past decade. This paper gives a comprehensive overview of the state-of-the-art approaches in question classification and provides a detailed comparison of recent works on question classification and discussed about possible extensions to QC problem.
A Support System Based on Movie and Sound Processing for Building Streaming Contents of the Assembly Minutes

Recently it becomes reasonable to stream video contents according to the broadband popularization. In administrative organizations the importance of free access policy to self-governing body information, such as a broadcast of the assembly, enrich their WEB pages, etc., has been widely recognized. This paper presents a support system based on movie and sound processing for building streaming media contents about the assembly information. The content includes video contents of the assembly and superimposed dialogue of speech text. We apply combined method of frame difference with restricted area in movie processing and discrimination based on the cepstrum in sound processing to build such contents in the support system. Through numerical examples, we show concepts of the support system.
Recognition of human activities from still image using novel classifier

The quest for recognizing human activities and categorizing their features from still images using efficient and accurate classifier is never ending. This is more challenging than extracting information from video due to the absence of any prior knowledge resembling frames stream. Human Activities Recognition (HAR) refers to computer identification of specific activities to aid understanding of human behaviors in diversified applications such as surveillance cameras, security systems and automotive industry. We developed a novel model for classifier and used it in three main stages including preprocessing (foreground extraction), segmentation (background subtraction) to extract useful features from object and sort out these features by the classifier (classification). The model is further simulated using MATLAB programming. Our new classifier generates slightly different results for still image based on dataset INRIA and KTH for 780 images of (64*128) pixels format obtained from literature. The recognition rate of 86.2% for five activities such as running, walking, jumping, standing and sitting achieved by us is highly promising compared to the existing one of 85% over last decade.

Dynamic harmonic domain modelling of synchronous machine and transmission line interface

This study presents a methodology for analysing the transient behaviour of harmonics associated with the interfacing of a synchronous generator and a transmission line. The algorithm is derived entirely in the dynamic harmonic domain that is based on an orthogonal basis and on operational matrices. The main characteristics of the proposed method are: its capability to accurately follow the harmonic content of a transient without the aid of a post-processing tool and its ability to serve as a visually active indicator of the steady-state and transient conditions in a signal. The proposed method is validated by comparing its results against those obtained through a time-domain technique.
Facteurs déclenchants des décompensations cardiaques chez les sujets âgés

L’insuffisance cardiaque aigue est une cause frequente d’hospitalisation chez les sujets âges et represente un tournant evolutif pejoratif. Les facteurs declenchants de ces decompensations sont mal connus et semblent difficiles a identifier dans le contexte de l’urgence. L’objectif de notre travail est d’etudier ces facteurs declenchants ainsi que l’influence sur le pronostic de tels facteurs et de leur meconnaissance, chez des patients âges. Nous avons conduit une etude retrospective, multicentrique, portant sur 234 sujets âges, hospitalises en geriatrie aigue apres un passage aux urgences pour un episode de decompensation cardiaque. Nous avons etudie les facteurs declenchants aux urgences et en geriatrie, la mortalite intra-hospitaliere, les re-hospitalisations au 30e jour. Un facteur declenchant a ete retrouve dans 73% des cas, essentiellement representes par les infections (71%) dont les infections broncho-pulmonaires (60%), le passage en fibrillation atriale (19%), l’anemie (12%), l’inobservance therapeutique (9%), l’ischemie myocardique (9%), les poussees hypertensives (7%), la iatrogenie (4%), les embolies pulmonaires (4%). Ce facteur declenchant a ete meconnu aux urgences dans 32% des cas sans que cela soit associe a un mauvais pronostic. Le seul facteur associe de facon statistiquement significative a un mauvais pronostic est un index de severite du score de CIRS-G eleve. Nos resultats montrent qu’un facteur declenchant existe dans un grand nombre de cas lors des decompensations cardiaques chez les patients âges admis aux urgences. Le pronostic a court terme ne semble pas influence par l’existence d’un facteur declenchant ou par sa mise en evidence ou non par l’urgentiste.
Quality of life and self-esteem of adolescents with diabetes mellitus

Objective: To evaluate the quality of life related to health (QLRH) and self-esteem (SE) of adolescents with Diabetes Mellitus type 1 (DM1) and analyze the relations between these constructs in this population. Methods: 124 adolescents with DM1, aged 12 to 18, answered the instruments validated for Brazil about Self-Esteem and Diabetes Quality of Life for Youths while they waited for their medical appointments. Results: The adolescents evaluated their quality of life and self-esteem positively. The concepts of quality of life and selfesteem were positively related. Conclusions: The study participants’ QLRH and SE were considered good, overall. The SE and QLRH concepts were related, i.e., the higher the self-esteem, the better the quality of life of adolescents with DM1.

Setting Standards for Educational Evaluators

accept in advance that those responsible for programs are contracting for evaluations likely to lead to murky conclusions. They do need to be forewarned, however, what it is that they are contracting for. One hopes that; unlike the ten commandments, these standards will not be graven in stone and that they therefore will be subject to revision, amendment, and change of an evolutionary nature as the field itself grows and develops. If that is the case, then this document will have fulfilled its purpose and in the long run will be recognized as a sign of the coming of age of evaluation as a scientific and professional activity. Given that these standards were prepared by a committee and not pronounced by a single voice from a burning bush, they are an excellent beginning.

Plausible and Realtime Rendering of Scratched Metal by Deforming MDF of Normal Mapped Anisotropic Surface.

An effective method to render realistic metallic surface in realtime application is proposed. The proposed method perturbs the normal vectors on the metallic surface to represent small scratches. General approach to the normal vector perturbation is to use bump map or normal map. However, the bumps generated with those methods do not show plausible reflectance when the surface is modeled with a microfacet-based anisotropic BRDF. Because the microfacet-based anisotropic BRDFs are generally employed in order to express metallic surface, the limitation of the simple normal mapping or other normal vector perturbation techniques make it difficult to render realistic metallic object with various scratches. The proposed method employs not only normal perturbation but also deformation of the microfacet distribution function (MDF) that determines the reflectance properties on the surface. The MDF deformation enables more realistic rendering of metallic surface. The proposed method can be easily implemented with GPU programs, and works well in realtime environments.

Software Quality Measurement Through Testing

: Software complexity is measured by various metrics of software. Software metrics play an important role in analyzing and improving software quality. Some of the metrics like reliability, reusability, size, etc are proposed by early researchers and they were very useful in software quality measurement. Software measurement faces a number of challenges whose solution requires both innovative techniques and borrowings from other disciplines. Over the years, a number of techniques and measures have been proposed and accessed via theoretical and empirical analyses. This shows the theoretical and practical interest of the software measurement field, which is constantly evolving to provide new, better techniques to support existing and more recent software engineering development methods. Software metrics are often categorized into products and process metrics. The aim of this paper is to discuss and analyse the various metrics which is used for software quality measurement proposed by early authors in this field. And also find a new metrics to improvise the Network Oriented Software Quality Measurement process.
