Fast Pedestrian Detection for Intelligent Vehicle Based on FPGA and Monocular Vision

This paper presents a fast pedestrian detection algorithm for intelligent vehicle based on FPGA architecture, using AdaBoost algorithm and Haar features. We describe the hardware design including image scaling, integral image generation, pipelined processing as well as classifier, and parallel processing multiple classifiers to accelerate the computational speed of the pedestrian detection system. The proposed architecture for pedestrian detection has been tested using Verilog HDL and implemented in Xilinx Virtex-5 FPGA. Its performance has been measured about 38 times than the equivalent software implementation.
A new method for structure recognition in unsubtracted digital angiograms

Existing methods for automatically finding arteries in coronary angiograms rely on preprocessing. The authors develop a structure recognition system which is not sensitive to variations in image quality. This system utilizes a probabilistic contextual segmentation technique which performs image segmentation without preprocessing. This approach, the deformable template matcher, combines prior knowledge of the arterial tree, encoded as mathematical templates, with a stochastic deformation process described by a hidden Markov model. An introduction to the technique is presented along with recent enhancements of the structure recognition system. <<ETX>>
Community-Based Strength Training Improves Physical Function in Older Women With Arthritis

Exercise is recognized as a mainstay treatment of arthritis, yet more than 40% of adults with arthritis report no leisure time physical activity participation. The Centers for Disease Control and Prevention is working to identify and promote evidence-based physical activity programs to improve physical function among adults with arthritis. The authors conducted a multisite, pilot randomized controlled trial to examine the effects of community-based strength training versus usual activity in women (n = 33) 55 years of age and older with arthritis. The moderate-intensity, progressive strength training intervention included balance and flexibility exercises. Classes met 2 times per week for 12 weeks. Outcome measures included muscle strength, performance-based physical function (mobility, flexibility, and balance), and arthritis symptoms. Lower body strength improved from baseline to 12 weeks in the strength training versus control group (32.2%-7.3%, respectively; P = .004). Physical function improved in the strength training group over 12 weeks (range, 7%-50%; P < .05), with no change in control group. Adherence to the intervention was 82% ± 16%. There were no adverse effects on arthritis symptoms. These results demonstrate the efficacy of this program and its potential to be disseminated as an evidence-based strength training intervention to improve physical function and strength among older women with arthritis and other major comorbidities.
A New ECT Image Reconstruction Algorithm Based on Convolutional Neural Network

In order to solve the problem of image reconstruction in electrical capacitance tomography (ECT) technology, the feasibility of applying convolutional neural network (CNN) to ECT image reconstruction is studied. The convolution layer and the training of the structure of the sub sampling method is improved based on deep research for convolution neural network for the more time-consuming process of deep structure and training issues, and a fast convergence convolution neural network (FCCNN) image reconstruction method is proposed. Matlab was used to build a ECT simulation system. For each algorithm, the simulation results were compared and analyzed. The experimental results show that our algorithm improved the image reconstruction efficiency and quality of the common flow pattern.
Algorithmes probabilistes appliqués à la durabilité et à la mécanique des ouvrages deGénie Civil

Cette etude presente des applications des methodes probabilistes en Genie Civil pour l’estimation de la fiabilite et de la durabilite des ouvrages. Deux methodes probabilistes performantes en termes de temps de calcul et de precision sont developpees. La premiere methode est une amelioration de la technique du gradient projete et permet l’utilisation efficace de l’algorithme de Rackwitz-Fiessler, en integrant dans ce dernier la prise en compte de l’imprecision numerique du modele associe a la fonction de defaillance, imprecision conduisant dans bien des cas a l'echec de l'algorithme. La seconde methode est une amelioration d’une methode de surface de reponse et permet de minimiser le cout de calcul en assurant la precision des resultats grâce a deux systemes de ponderation pour les points de calage. Ces deux methodes probabilistes sont ensuite appliquees a la durabilite d’ouvrages de Genie Civil par couplage avec des modeles de calculs aux elements finis. L’etude aborde deux problemes de durabilite souvent rencontres en Genie Civil : la carbonatation du beton et l’endommagement lie a la perte de precontrainte par retrait et fluage du beton d’un ouvrage en beton precontraint. - This study deals with the application of probabilistic methods to Civil Engineering structures in order to assess their reliability and durability. Two probabilistic methods efficient in terms of the computational time and the accuracy are developed. The first one which is an improvement of the projected gradient method allows using the Rackwitz-Fiessler’s algorithm efficiently, by accounting for the numerical inaccuracies involved by the model associated to the limit state function and frequently causing convergence unstability. The second one which is an improvement of a response surface method allows reducing the computational time while producing satisfactorily results thank to two weighting regression techniques for fitting points. Both probabilistic methods are then applied to the durability of Civil Engineering structures by coupling with the finite element method. The study deals with two typical durability problems of Civil Engineering concrete structures: on the one hand the carbonation of concrete which allows the reinforcing bars to be depassivated and the corrosion to be initiated and on the other hand the loss of prestressing forces due to shrinkage and creep of concrete which can lead to various damages in presstressed structures
Évaluation de la fréquence des micronoyaux et du potentiel clastogène et/ou aneugène du benzo-a-pyrène suite à une exposition in vitro des lymphocytes humains

Le benzo-a-pyrene (BaP) est un cancerogene reconnu pour l'homme, contaminant present dans notre environnement. Il cause des dommages a l'ADN que nous avons mesures dans les lymphocytes exposes a de faibles concentrations de BaP, provenant de 20 jeunes volontaires non fumeurs et en sante. Suite a l’exposition, la frequence des micronoyaux (MN) augmente significativement et decrit une courbe dose-reponse non lineaire, suggerant le declenchement du processus de detoxification et la reparation de l’ADN. Des differences entre les individus et entre les sexes sont presentes dans la reponse genotoxique produite par le BaP. Le test des aberrations chromosomiques montre que le pourcentage de chromosomes casses augmente significativement dans les cellules exposees au BaP. Combines avec l'augmentation de la frequence des MN, nos resultats confirment l'effet clastogene du BaP deja rapporte dans la litterature. L’hybridation in situ en fluorescence (FISH) des MN avec une sonde pancentromerique est aussi utilisee pour etablir leur mecanisme de formation. La FISH revele que la majorite des MN formes apres une exposition au BaP contient un centromere et plus, ce qui est significativement different de la condition non exposee. Plus precisement, dans nos conditions experimentales, les MN induits par le BaP contiennent surtout trois centromeres et plus, indiquant egalement la presence d'un effet aneugene. L'effet clastogene du BaP est relie a son role d'initiateur dans la cancerogenese, alors que l'effet aneugene le relierait a l'etape de progression. Ces resultats sont importants puisque l'exposition aux composes de la classe du BaP est de longue duree (cigarette, air pollue).
Statistical methods for the analysis of covariance and spatio-temporal models

A new hierarchical model is proposed for the analysis of covariance with random, unequal variances. Bayesian inference for the new model depends upon uncertainty in the degrees of freedom for a chi-squared distribution. The convergence of MCMC is validated by extremely accurate Laplacian approximations. Practical applications include neuropsychological tests in offender profiling and nutrition data. As a special case, the parallel line model with equal variances is considered, and alternatives to the F-test for the equality of the group effects, including Bayes factors, are investigated. In the final chapter, a self-similarity spatio-temporal model for the pressures of oil wells in an Alaskan oil field is considered, and our Bayesian techniques are extended to this situation with a view towards future interdisciplinary research.

Review of « Hervé Lieutard (2004), Phonologie et morphologie du parler occitan de Graulhet (Tarn). Structure, contenu et rôle de la syllabe », CEO, Université Paul Valéry – Montpellier III

This book analyses the phonology and morphology of a Western Lengadocian dialect and is based on the author’s PhD thesis. It contains six chapters, with the first and the last one serving as introduction and conclusion to the work, respectively. It also has an index of the word forms, an index of the tables, a references section, three appendices which contain the conjugation paradigm of 34 Occitan verbs, an example of the data in the corpus in phonetic transcription, as well as literary texts written in the Graulhet dialect, and an explanation of the phonetic symbols and abbreviations used. In this review, I won’t be able to go into details for the analysis of every single one of the many phenomena studied, although much interesting discussion would be possible, but I will try to outline the main tenets of the book and in particular the basics of the theory that served as the framework for the analyses.

Weekly scheduling of cisplatin: feasibility, efficacy and perspective

textabstractIn this thesis studies of weekly administration of cisplatin are presented. Weekly administration of cisplatin is not new: already in the seventies weekly cisplatin regimens were explored but they were abandoned because of hematologic, renal and gastrointestinal toxicity. The administration of cisplatin in the outpatient setting and without adequate hydration certainly has contributed to the failure of these studies. A better understanding of the pathophysiology of renal toxicity led to hydration programs and the introduction of hypertonic saline; the development of a new generation of antiemetics ameliorated nausea and vomiting considerably and made it possible to administer cisplatin more frequently. Reexploration of weekly cisplatin thus became possible. The theory behind weekly administration of cisplatin is based on the tumor biologic principle that frequent administration of chemotherapy in a high dose kills cancer cells more effectively and probably reduces the risk of the development of resistance. Treatment with weekly intervals also has the theoretical advantage that sensitive cells, in which DNA-repair is less effective than in resistant cells, have less time for regrowth compared to conventional 3-week schedules. In this introduction the cytotoxic drugs used in our studies, cisplatin and etoposide, will be briefly discussed as well as the tumor types in which they were studied: head and neck cancer, non-small cell lung cancer and pleural mesothelioma. The indications for chemotherapy in these tumor types as well as the treatment results with cisplatin with or without etoposide will be presented to enable reference with the results presented in this thesis.
UN MODELO DE RECUPERACIÓN DE INFORMACIÓN BASADO EN SVMs INFORMATION RETRIEVAL MODEL BASED ON SVMS

Classifiers like the SVMs (Support Vector Machines) were used to organize documents very efficiently, but their effectiveness has not been verified in Information Retrieval for document hierarchizing. This paper proposes a transformation that associates the IR process to a new vectorial space where a SMVs-based classifier is trained to learn the concept of similarity with documents.
Severe hand-foot-mouth disease:a report of 3 autopsied cases

Purpose To investigate the clinicopathological features of severe hand-foot-mouth disease by autopsy,and to analyze the cause of the patient's dead.Methods Autopsies were performed on three cases of severe hand-foot-mouth disease,the pathological changes were studied by light microscopy,the correlation between the pathological changes and the clinical signs and symptoms was analyzed,and the reasons resulting in the death of patients were discussed.Results Severe hand-foot-mouth disease occurred suddenly and progressed rapidly with a short duration.The patients presented with hand,foot and mouth vesicular eruptions and sudden onset of respiratory failure accompanied by nervous system manifestations.The mainly involved organs were the medulla oblongata,brain stem and the lung.The brain stem and the medulla oblongata exhibited the degeneration and necrosis of the neurons,encephalomalacia,lymphocytic infiltration around the vessels,neuronophagia and the formation of glial cell nodules,which was consistent with the viral encephalitis.The lung showed the widening of alveolar septa,the congestion of capillaries and the infiltration of a large number of macrophages,which also effused into the alveolar space,resulting in focal lung consolidation.The exudate in the alveolar space and the hyaline membrane were focally present.Focal pulmonary infarction was observed due to the pulmonary embolism.The changes in the lung were consistent with the interstitial pneumonia and acute pulmonary edema.Additionally,the lymph nodes and the spleen showed structural destruction by showing the follicular atrophy and the karyorrhexis of the cells in the follicular center,or a burning-out feature.Conclusions In the severe hand-foot-mouth disease,the virus not only involves the skin and oral mucosa,but also the medulla oblongata,brain stem and the lung,resulting in the viral encephalitis,viral pneumonia and neurogenic pulmonary edema,and consequently leading to the respiratory failure,which is responsible for the patient's death.
Using a customized search engine to address low health literacy: a program description

In the provision of health information, it is the structure as much as the content of an information source that can influence a patient's ability to understand and act upon medical guidance. Canada has a commitment to providing equal, quality health care to all citizens, but a barrier to this equality has emerged as health information has gone online. This paper discusses the online information retrieval system in a patient library in a Canadian hospital, the barrier that this system created in connecting patients with health information, and how resources were reorganized to more equitably meet the needs of patients. The example of one information retrieval system provides a new frame through which to evaluate the organization of electronic information in health care settings.
An in vivo investigation of choroidal vasculature in age-related macular degeneration

Age-related macular degeneration (AMD) is the leading cause of visual impairment in the developed world. Whilst the pathogenesis is complex and not fully understood, changes to the choroidal vasculature in AMD have been demonstrated using histology. Advances in imaging technology, particularly long-wavelength optical coherence tomography (OCT), allow in vivo visualisation and investigation of this structure. The aim of this work is to determine whether changes to the choroidal vasculature are detectable in AMD using in vivo imaging. This was achieved through the evaluation of parameters for quantifying the structure, and the application of a machine learning approach to automated disease severity classification, based on choroidal appearance. Participants with early AMD (n=25), neovascular AMD (nAMD; n=25), and healthy controls (n=25) underwent imaging with a non-commercial long-wavelength (λc=1040 nm) OCT device. Subfoveal choroidal thickness, choroidal area, and luminal area were significantly lower in the nAMD group than the healthy and early AMD groups, whilst vessel ratio was significantly greater (P<0.05 in all cases). There was no significant difference in visible vessel diameter, choroidal vascularity index, luminal area ratio, or luminal perimeter ratio between the groups. No significant differences were found between the healthy and early AMD groups for any of the eight vascular parameters assessed. Classification of the disease groups based on choroidal OCT images was demonstrated using machine learning techniques. Textural features within the images were extracted using Gabor filters, and K-nearest neighbour, support vector machine, and random forest classifiers were assessed for this classification task. Textural changes were most pronounced in late-stage disease, although attribution to pathology or pharmacological intervention (anti-VEGF treatment) was not possible. Changes were also discernible in the early AMD group, suggesting sensitivity of this approach to detecting vascular involvement in early disease. In conclusion, structural changes to the choroidal vasculature in AMD are detectable in vivo using OCT imaging, demonstrated with both manual and automated analysis techniques. Whilst changes were most prominent in late-stage disease, subtle structural changes in early AMD were identified with texture analysis, warranting further investigation to improve our understanding of choroidal involvement in the pathogenesis of early AMD.
