Texto completoMinimally invasive image-guided laparoscopic surgery allows shorter hospital stays for the patient reducing post-operative trauma and faster healing time. With the recent advances in imaging techniques, surgeons can efficiently and confidently plan a surgery by using different image modalities such as CT/MRI scans, ultrasound images etc. Real-time image fusion techniques can overlay the images from different modalities together to provide a comprehensive view to the surgeon. An important aspect of real-time fusion is that the laparoscopic instrument is tracked in real-time using sensors. In this thesis, we present a detailed analysis of such tracking technologies while providing a novel sensor setup for ultrasound laparoscope image tracking. We present a kinematic chain for the sensor setup and provide a solution for noise reduction in the sensor data using rotation averaging technique. Hand-Eye calibration is also a fundamental part of hybrid tracking systems. We present a detailed review of this technique. We also present a deterministic, robust and accurate method for solving Hand-Eye calibration problem even for large amounts of outliers and high levels of measurement noise. The proposed method is based on a reformulation of a rank-constrained semi-definite programming problem allowing for robustness to be enforced via an iteratively re-weighted optimization approach

Texto completoUndersökningens syfte var att ta reda på hur viktig kulturell kompetens är i vägledning av personer med multikulturell bakgrund. Jag vill även belysa att vad som ses som normalt i en kultur kan betyda något helt annat i en annan. Undersökningen går även in på kulturkrockar och dess problematik i samband med vägledning. Metoden som använts i undersökningen är kvalitativ, och de fem respondenter som intervjuades var alla praktiserande muslimer. Den teoretiska utgångspunkten i undersökningen är den konstruktivistiska. Undersökningen visar att individerna på olika sätt kompromissar för att få deras vardag att gå ihop med sin religiösa trosuppfattning. En slutsats som drogs är att kulturell kompetens till viss del är nödvändig, dock är det vägledarens förhållningssätt som är avgörande för om det blir ett lyckat möte.

Texto completoRésumé : À la suite d’un accident vasculaire cérébral (AVC), plusieurs atteintes, comme un déficit de timing, sont notées, et ce, même à la phase chronique d’un AVC, ce qui nuit à l’accomplissement de tâches quotidiennes comme se vêtir. L’entrainement robotisé est un entrainement qui est de plus en plus préconisé dans le but d’améliorer la récupération motrice à la suite d’un AVC. Par contre, la plupart des études ont étudié les effets de l’entrainement robotisé sur l’amélioration de l’aspect spatial du mouvement (ex : la direction du mouvement), et non l’aspect temporel (ex : timing). L’objectif principal de ce projet était donc d’évaluer et de comparer l’impact de deux entrainements robotisés sur l’amélioration immédiate du timing soit : la réduction de l’erreur (RE), qui consiste à guider la personne à faire le mouvement désiré, et l’augmentation de l’erreur (AE), qui nuit au mouvement de la personne. L’objectif secondaire consistait à explorer s’il y avait une relation entre le côté de la lésion cérébrale et le changement dans les erreurs de timing suivant l’entrainement par RE et AE. Trente-quatre personnes atteintes d’un AVC au stade chronique (âge moyen de 67 ± 7 années) ont participé à cette étude, où ils devaient jouer à un jeu simulé de machine à boules. Les participants devaient activer une main robotisée au bon moment pour atteindre des cibles présentées aléatoirement sur un écran d’ordinateur. Les participants recevaient soit RE ou AE. Une ligne de base et une phase de rétention étaient données avant et après chaque entrainement, et elles étaient utilisées pour évaluer et comparer l’effet immédiat de RE et AE sur le timing. Les résultats ont démontré que RE permet d’améliorer les erreurs de timing (p=0,03), mais pas AE (p=0,45). De plus, la comparaison entre les deux entrainements a démontré que RE était supérieur à AE pour améliorer le timing (p=0,04). Par ailleurs, une corrélation significative a été notée entre le côté de la lésion cérébrale et le changement des erreurs de timing suivant AE (r[indice inférieur pb]=0,70; p=0,001), mais pas RE (r[indice inférieur pb]=0,18; p=0,24). En d’autres mots, une détérioration de l’exécution de la tâche de timing a été notée pour les participants ayant leur lésion cérébrale à gauche. Par contre, ceux ayant leur lésion à droite ont bénéficié de l’entrainement par AE. Bref, l’entrainement par RE peut améliorer les erreurs de timing pour les survivants d’AVC au stade chronique. Toutefois, le côté de la lésion cérébrale semble jouer un rôle important dans la réponse à l’entrainement par AE. Ceci demeure à être exploré, ainsi que l’impact d’un entrainement par RE et AE de plus longue durée pour en déterminer leurs effets à long terme.

Texto completoThe rank aggregation problem is to build consensus among a set of rankings (ordered elements). Although this problem has numerous applications (consensus among user votes, consensus between results ordered differently by different search engines ...), computing an optimal consensus is rarely feasible in cases of real applications (problem NP-Hard). Many approximation algorithms and heuristics were therefore designed. However, their performance (time and quality of product loss) are quite different and depend on the datasets to be aggregated. Several studies have compared these algorithms but they have generally not considered the case (yet common in real datasets) that elements can be tied in rankings (elements at the same rank). Choosing a consensus algorithm for a given dataset is therefore a particularly important issue to be studied (many applications) and it is an open problem in the sense that none of the existing studies address it. More formally, a consensus ranking is a ranking that minimizes the sum of the distances between this consensus and the input rankings. Like much of the state-of-art, we have considered in our studies the generalized Kendall-Tau distance, and variants. Specifically, this thesis has three contributions. First, we propose new complexity results associated with cases encountered in the actual data that rankings may be incomplete and where multiple items can be classified equally (ties). We isolate the different "features" that can explain variations in the results produced by the aggregation algorithms (for example, using the generalized distance of Kendall-Tau or variants, pre-processing the datasets with unification or projection). We propose a guide to characterize the context and the need of a user to guide him into the choice of both a pre-treatment of its datasets but also the distance to choose to calculate the consensus. We finally adapt existing algorithms to this new context. Second, we evaluate these algorithms on a large and varied set of datasets both real and synthetic reproducing actual features such as similarity between rankings, the presence of ties and different pre-treatments. This large evaluation comes with the proposal of a new method to generate synthetic data with similarities based on a Markov chain modeling. This evaluation led to the isolation of datasets features that impact the performance of the aggregation algorithms, and to design a guide to characterize the needs of a user and advise him in the choice of the algorithm to be use. A web platform to replicate and extend these analyzes is available (rank-aggregation-with-ties.lri.fr). Finally, we demonstrate the value of using the rankings aggregation approach in two use cases. We provide a tool to reformulating the text user queries through biomedical terminologies, to then query biological databases, and ultimately produce a consensus of results obtained for each reformulation (conqur-bio.lri.fr). We compare the results to the references platform and show a clear improvement in quality results. We also calculate consensus between list of workflows established by experts in the context of similarity between scientific workflows. We note that the computed consensus agree with the expert in a very large majority of cases
Safeea, Mohammad. "Des robots manipulateurs collaboratifs sûrs". Thesis, Paris, HESAM, 2020. http://www.theses.fr/2020HESAE036.
Texto completoCollaborative industrial manipulators are ushering a new era in flexible manufacturing, where robots and humans are allowed to coexist and work side by side. However, various challenges still persist in achieving full human robot collaboration on the factory floor. In this thesis two main challenges - safety and collaboration - for achieving that goal are addressed. On safety, the thesis presents a real-time collision avoidance method which allows the robot to adjust the offline generated paths of the industrial task in real-time for avoiding collisions with humans nearby. In addition, the thesis presented a new method for performing the reactive collision avoidance motion using second order Newton method which offers various advantages over the traditional methods in the literature. On collaboration, the thesis presents the precision hand-guiding as an alternative to the teach-pendant for performing precise positioning operations of the robot’s end-effector in a simple and intuitive manner. The thesis also presents new contributions into the mathematical formulation of robot dynamics, including a recursive algorithm for calculating the mass matrix of serially linked robots with a minimal second order cost, and a recursive algorithm for calculating Christoffel symbols efficiently. All the presented algorithms are validated either in simulation or in a real-world scenario

The purpose of this research is mainly an evaluation program for college student volunteers participating Hand-in-Hand Guidance Project for children's home. Using CIPP evaluation mode to analysis in four categories which includes, Context, Input, Process and the Product. On the other hand, the way of research covers: Focusing Group Interview, Semistructure Interview and Document Analysis Method. After the research, primary needs of mental company of children in children’s home include: (1) Having someone to listen to then. (2) Security. (3) Trust relationship. (4) Discussing and deal with adaption problem. (5) Caring and company with a steady relationship. The expectations of children’s home include: (1) The role of company with children. (2) Positive model. (3) Helping to understand and evaluate children’s situation. (4) Caring ignored children. On the other side, the findings of Process and Product evaluation in CIPP evaluation mode show that college student volunteers use listening, empathy, caring, understanding, compliment, and mild response as the ways, to bring children relax, happiness, looking forward to meeting and not to closing the relationship, and building healing and steady helping relationship. In summary, this project fulfills children’s needs, and relieves the pressure of the manpower of a children’s home, helping socialworkers to understand children’s life situations and needs, and acting positive role and guide children to deal with problems in positive ways. However, we are facing several challenges, such as: (1) The balance between information flow and confidentiality principle. (2) The complex of information tract. (3) Unstable administration, fund and cooperation of children’s home. (4) Lack of information to pair. (5) Influences by college student volunteers’ planning on time, schoolwork and participate in associations. (6) The Influences by equipment and other workers in children’ home. Generally speaking, positive evaluations were given by study participants to the help to children and children’s home, and to enhance volunteer’s professional experience. Largely due to the great effort, it is strongly recommended that this project should be continualy processed. Finally, the researcher concludes suggestions provided by study participants, which include: (1) The program’s operation system should be more integrated. (2) To keep the communication smooth on system collaboration. (3) To increase courses about helping handicapped children. (4) To build security and trust workspace in children’ home. (5) Volunteers’s caring and company with the children is more important than problem solving or possible change.

Texto completoThe aim was to evaluate the prevalence of hand and wrist pain, as well as the relationships between occupational overuse syndromes in the hands and wrists of chiropractors in South Africa as a result of their daily use of manual therapy techniques while at work. There are very few statistics available that disclose the nature and incidence of work related injuries. However those statistics that do exist suggest that hands on patient activities place physical therapists at greater risk of injury in comparison to other health care workers (Lunne et al., 2000). A study conducted by Bork et al.(1996) determined the prevalence of work-related musculoskeletal injuries sustained by physical therapists. Hand pain (29.6%) and back pain (45%) where the leading cause of pain in physical therapists (Bork et al., 1996.) Chiropractic and physiotherapy are both health care professions that specialize in the treatment of disorders pertaining to the neuro-musculo-skeletal system (Hunter, 2004). Physical therapists use manual therapy techniques as part of their daily working activities, so it can be assumed that chiropractors too will have a high prevalence of hand and wrist pain as they utilize similar therapeutic techniques to physical therapists. Cromie et al.(2000) evaluated the prevalence, severity, risks, and responses of disorders in physical therapists. He identified 4 categories of major risk factors commonly associated with workers musculo-skeletal disorders in physical therapists 1. Risk factors related to specific activities. 2. Postural risk factors. 3. Risk factors with regard to work load issues 4. Risk factors in regard of work capacity and health of the participant (Cromie et al., 2000). Physical risk factors found to be associated with neck, shoulder, or hand and wrist disorders in cross sectional studies are heavy lifting, monotonous work, static work postures, vibrations and repetitive jobs, and a high work pace (Alfredsson et al., 1999). Other factors that have been associated with musculoskeletal pain are higher age and female gender (de Zwart et al., 2001; Wahlstedt et al., 2001; Feveile et al., 2002).
