Conditional models for 3D human pose estimation:
No full textHuman 3d pose estimation from monocular sequence is a challenging problem, owing to highly articulated structure of human body, varied anthropometry, self occlusion, depth ambiguities and large variability in the appearance and background in which humans may appear. Conventional vision based approaches to human 3d pose estimation mostly employed "top-down methods", which used a complete 3d human model, in a hypothesized pose, to explain the configuration of the humans in the observed 2d image. In this thesis, we work with "bottom-up methods" for human pose estimation, that use low level image features to directly predict 3d pose. The research draws on recent innovations in statistical learning, observation-driven modeling, stable image encodings, semi-supervised learning and learning perceptual representations. We address the problems of (a) modeling pose ambiguities due to 3d-to-2d projection and self occlusion, (b) lack of sufficient labeled data for training discriminative models and (c) high dimensionality of human 3d pose state space. In order to resolve 3d pose ambiguities, we use multi-valued functions to predict multiple plausible 3d poses for an image observation. We incorporate unlabeled data in a semi-supervised learning framework to constrain and improve the training of discriminative models. We also propose generic probabilistic Spectral Latent Variable Models to efficiently learn low dimensional representations of high dimensional observation data and apply it to the problem of human 3d pose inference.Ph.D.Includes bibliographical references (p. 182-193)by Atul Kanauji

Business and Politics in India
No full textOverview Description Table of Contents Author InformationCoverBusiness and Politics in IndiaEdited by Christophe Jaffrelot, Edited by Atul Kohli, and Edited by Kanta MuraliModern South AsiaDescriptionOver the last few decades, politics in India has moved steadily in a pro-business direction. This shift has important implications for both government and citizens. In Business and Politics in India, leading scholars of Indian politics have gathered to offer an analytical synthesis of this vast topic. Collectively, they cover the many strategies that businesses have used to exert their newfound power in recent times and organize the book around a few central concerns. They first analyze the nature of business power and how it shapes political change in India. Second, they look at the consequences of business' growing power on some important issue areas-labor, land, urban governance, and the media. Finally, they take account of regional variation and analyze state-business relations. This definitive account offers significant insights into how and why corporations have increased their power in contemporary Indian politics
Medication adherence in hypertension
No full textSuboptimal adherence to antihypertensive medication is a major contributor to poor blood pressure control. Several methods, direct or indirect, are available for measuring adherence, including the recently developed biochemical screening, although there is no gold-standard method routinely used in clinical practice to accurately assess the different facets of adherence. Adherence to treatment is a complex phenomenon and several of the barriers to adherence will need to be addressed at the healthcare system level; however, when looking at adherence from a more practical side and from the practitioner's perspective, the patient–practitioner relationship is a key element both in detecting adherence and in attempting to choose interventions tailored to the patient's profile. The use of single-pill combinations enabling simplification of treatment regimen, the implementation of a collaborative team-based approach and the development of electronic health tools also hold promise for improving adherence, and thus impacting cardiovascular outcomes and healthcare costs
Cost-conscious designing of Dutch transportation infrastructure projects: A first explorative research into the ‘control’ based factors for reducing the front-end cost escalations
No full textCost overruns in infrastructure projects has been a well-known phenomenon for almost a decade. As per the generally accepted definition, the industry has been measuring cost overruns as the cost exceedance with respect to the approved contractor’s budget. But researchers are realizing the fact that the decision-to-build is generally taken long before the ‘budgeting’, which thereby falsifies the existing definition of ‘cost overruns’. It has been henceforth also realized that projects under overruns also don’t offer the best capital value because their as-built costs exceed the costs estimated for them during the “decision-to-build” stage. As a result, such projects debar other deserving projects from getting approved by the funding authority/infrastructure ministry, which could potentially deliver more value for the same invested costs. A lot of projects which were in high overruns in the recent past shouldn’t have been approved/funded/preferred by the decision makers over others (For example: The Channel Tunnel in the UK, cost overruns = 100%, Denver intl. airport in the USA, cost overruns =200%). Consistent overruns also indicate that even with consecutive projects, the experts are not learning to improve on it as well. As a result, cost overruns in infrastructure projects have been a subject of discussion for more than 2 decades now. It has been realized that not only the estimates presented to the decision makers should be accurate, but also the total project costs post approval (at the decision to build point) should adhere (be controlled) to the approved estimate. Either of the two situations/or both would lead to cost escalations/overruns. Researchers have been demanding more exploration on the front-end cost escalations of the projects rather than on the cost overruns in the execution phases. It has been realized that the front-end phases allow for the maximum control over the as-built costs, but ironically, the industry experiences more cost escalations in the front-end phases. It has been emphazied that ex-post studies on the front-end phases of projects can bring revelations on how projects suffer front-end escalations. Limited research exists on the front-end phases of infrastructure projcts, with almost all of them based on the Nordic countries and only one on the Dutch governance setting by Nijkamp & Ubbels (1998). The limited research mostly includes the studies that have produced ‘characteristic escalation figures’ & the ‘factors/causes’ (technical, political & cognitive). All these factors except ‘technical & cognitive’ are quite external to the project teams and are difficult to research on through ex-post studies. Citing ‘political factors’ as the prime cause, most researches on the ‘solutions’ counterpart have been discussing over ‘political misrepresentation’ as the main factor/cause of front-end cost escalations. Very less researches have been done on the ‘technical & cognitive’ factors, which are more internal to the project teams and can be easily studied through the ex-post researches on the front-end phases of recently completed infrastructure projects. This thesis aimed to gather such ‘technical/control’ based factors & their data collection/analysis methods, in order steer them for controlling the total project costs from the very front-end phases itself. This thesis gathered 19 such ‘control’-based technical factors from Arcadis cost experts and considered it as the starting point. Structured-questionnaire surveys then helped to filter out the most important factors which lead to front-end cost escalations. Finally, 12 interviews from two recent Dutch projects (Schiphol Expansion : Landside works & Redevelopment of highway N270) gave insights on what approach should be taken for data collection [cross-learning (CL)/open-data gathering (OA)] & data analysis [top-down (TD)/bottom-up (BU)] methods in order to steer the ‘factors’ in the front-end phases of the projects. The thesis concluded that ‘project-control’ based technical factors are crucial as well, and can be steered. The research results gave some insights on which data collection/analysis approaches should be taken for steering each of such ‘factor’ from the front-end phases itself. The thesis conclusively highlighted the need of further research on gathering more such ‘factors’ and obtaining suitable data collection (CL/OA) & data analysis (TD/BU) methods for steering them. The need to focus on ‘project controls’ based factors (and not just political factors) from the very front-end phases was also conveyed.Civil Engineering | Construction Management and Engineerin
Modulation of the cardiovascular autonomic nervous system by non pharmacological treatment : application in systolic chronic heart failure and peripheral arterial disease
No full textLa prise en charge des maladies cardiovasculaires vise à lutter contre les anomalies du système nerveux autonome cardiaque (SNA) en restaurant la balance sympatho-vagale avec l'aide de moyens pharmacologiques ou non pharmacologiques. Nous avons montré que l'exercice physique intermittent (EI) chez l'insuffisant cardiaque chronique (IC) permettait de majorer le tonus vagal. L'EI était plus efficace que l'exercice continu pour obtenir une réduction des arythmies. Dans un deuxième travail nous avons montré que l'électrostimulation musculaire des membres inférieurs chez l'IC permettait de réduire le tonus sympathique en lien avec une stimulation des afférences. Dans l'artériopathie oblitérante des membres inférieurs (AOMI) enfin, nous montrons que l'électrostimulation sensitive des membres inférieurs permettait d'améliorer la distance de marche via des mécanismes potentiellement sympatho-inhibiteur.The management of cardiovascular disease is to fight against abnormal heart autonomic nervous system (ANS) by restoring sympatho-vagal balance with the help of pharmacological or non-pharmacological means. We have shown that intermittent exercise (IE) in patients with chronic heart failure (CHF) allowed to increase the vagal tone. The IE was more effective than continuous exercise for reducing arrhythmias. In a second work we have shown that electrical muscle stimulation of the lower limbs in CHF reduced sympathetic tone related to stimulation of afferents. In peripheral arterial disease (PAD) finally, we showed that the sensitive electrostimulation of lower limbs improved the walking distance via potentially sympatho-inhibitor mechanisms
