Full textAbstract:
Astronauts have complained of difficulty in grasping tools, hand fatigue, and hand/forearm pain during extravehicular activities. This study was conducted to examine hand grip performance with a bare hand and in a spacesuit glove at two different pressures, with three hand positions and two elbow positions. Sixteen subjects, selected from the suited-subject pool at the Johnson Space Center, gripped a hand dynamometer encased in a vacuum chamber designed to simulate the operating pressures in space. The results for the bare hand condition showed a significant effect for hand position and a significant elbow/hand interaction. The spacesuit glove at operating pressure was responsible for an average 42% grip strength decrement from the bare hand condition. A new procedure for determining hand size from projected hand surface area revealed that bare and gloved-hand grip strength was highly correlated with hand size, as were body weight, height, and forearm circumference.M.

Full textAbstract:
The thesis seeks to examine the validity of participation in the project of global ethic by Muslims in the light of the ethical system derived basically from the Qur'an. It is to investigate the basis upon which Muslims can co-operate with non-Muslims in the field of ethics, in a world that has become global. The hypothesis to be examined through this research is that the project seems to be beneficial for human society and we can find a support from within the Qur'anic ethical system. To examine this assumption, the research assessed the new international context i. e. the phenomenon of globalisation. Then it focuses on the pioneer and initiator of the project Hans Kung, to understand his background and motives behind the project. Subsequently, surveys some of the international (Christian and Muslim) responses towards the project. Finally the study highlights the basic elements of the ethical theory derived form the Qur'an to examine the congruence or non-congruence, the compatibility or non-compatibility, the common ground or not, between the project and the Qur'anic ethical system. The most important results of this research are that: The Islamic ethical system contains encouragement for Muslims to be part of such a universal project, but even with this encouragement, the priority for Muslims in situations of conflict with regards to any act required from the project, should ultimately be for their faith-based ethical principles. Apart from this restriction, and the possibility that the project might be abused as a new western tool of political domination, this research finds no reason why Muslims should not be part of the supportive and active groups in the project.

Background: Myths, misconceptions and a general lack of information surround the use of gloves and mittens in extreme cold environments. Objective. This study assessed how well an assortment of gloves and mittens performed in a very cold environment. Methods. A convenience sample of gloves and mittens were tested in Antarctica during the winter of 2016 using a calibrated thermometer (range: -148 degrees F to +158 degrees F/-1008C to +70 degrees C) three times over a 0.5-mile distance (similar to 20 minutes). A small sensor on a 10-foot-long cable was taped to the radial surface of the distal small finger on the non-dominant hand. The tested clothing was donned over the probe, the maximum temperature inside the glove/mitten was established near a building exit (ambient temperature approximately 54 degrees F/12 degrees C), and the building was exited, initiating the test. The hand was kept immobile during the test. Some non-heated gloves were tested with chemical heat warmers placed over the volar or dorsal wrist. Results. The highest starting (96 degrees F/36 degrees C) and ending (82 degrees F/28 degrees C) temperatures were with electrically heated gloves. The lowest starting temperature was with electrically heated gloves with the power off (63 degrees F/17 degrees C). Non-heated gloves with an inserted chemical hand warmer had the lowest minimum temperature (33 degrees F/1 degrees C). Maximum temperatures for gloves/mittens did not correlate well with their minimum temperature. Conclusions. Coverings that maintained finger temperatures within a comfortable and safe range (at or above 59 degrees F/15 degrees C) included the heated gloves and mittens (including some with the power off) and mittens with liners. Mittens without liners (shell) generally performed better than unheated gloves. Better results generally paralleled the item's cost. Inserting chemical heat warmers at the wrist increased heat loss, possibly through the exposed area around the warmer.

An apparatus was developed that provides a dynamic representation of the hand-glove interaction inside a baseball glove during catching situations. Until recent history, baseball manufacturers relied primarily upon player input and practical necessity to develop their technology; the use of scientific exploration was minimal. To add scientific technology to the design of baseball gloves, the project consisted of a sensor glove component and a visual interface, developed to better understand the hand-glove interaction. The sensor glove was created by attaching FlexiForce A201 sensors to a golf glove to fit inside a baseball glove. The sensors measure the forces in a variety of locations on the back and front of the hand. The project resulted in a simple user interface that presents a better representation of the hand-glove interaction and provides a means to better identify characteristics of glove use.

This research assesses possible methods for extending the Streamflow Prediction Tool from a streamflow forecasting model to a flood extent forecasting model. This new flood extent forecasting model would allow valuable and easy to understand information be disseminated in a timely manner for flood preparation and flood response. The Height Above Nearest Drainage (HAND) method and AutoRoute method were considered for flood extent models but the HAND was the better option for its simple and quick computation as well as its viability on a global scale. Due to the importance of Digital Elevation Models (DEMs) in these flood extent models, an analysis was performed on the sensitivity and response of different DEMs with the HAND method. The HAND method with the differing DEMs was also analyzed using the Streamflow Prediction Tool for model boundary conditions against Sentinel-1 SAR generated flood extent images from August 24, 2017. The MERIT DEM performed the best in this analysis and is recommended for future research in creating a global forecasting flood extent model. The HAND method covered about 25% of the generated flood extent images and more complex flood extent models may need to be considered in areas where HAND underperforms. Finally, a proof of concept flood extent model was created and deployed as a web application for easy accessibility and distribution of flood information. Additional research to consider is flood impact based on affected population or an economic analysis, as well as optimizing model parameters for increased accuracy and performance. Additional research is also needed for HAND DEM analysis in other parts of the world.

The interest in the research and development of humanoid robots has been steadily growing in recent years. The application of such robotic systems are many and wide. In this bachelor’s thesis in mechatronics one such robotic system was built in the form of a hand. The aim was to investigate how well the robotic hand could imitate the movements of a user-worn controller glove as well as grip objects, both through wireless communication. The controller glove consisted of an Arduino Nano microcontroller, five flex sensors, an inertial measurement unit that detected the wrist rotation of the glove, a nRF24L01 transmitter as well as an external power source of 9 volts. The robotic hand consisted of three-dimensional printed parts from an open source library, an Arduino Uno microcontroller, a nRF24L01 receiver, two external power supplies of 9 volts and 5 volts and six servo motors, with one servo motor per finger and wrist. The finished robotic hand did well in imitating the motions of the controller glove with little to no observed delay and was able to grip onto objects of various sizes, shapes and weights up to 134 grams. The constructed robotic hand achieved the desired goals of the project. The results indicated that improvements can be made on the grip ability of objects with rigid surfaces as well as improving the imitation by implementing more degrees of freedom for the fingers of the robotic hand.Intresset för forskning och utveckling av humanoida robotarhar under de senaste åren varit på ständig uppfart.

Full textAbstract:
The hand is one of the most complex of all of the anatomical structures in the human body. It has been found that hand injuries are among the most frequent injuries that occur to the body, predominantly during industrial activities. It has therefore been concluded that more research is needed into protective factors, such as glove use. The design features of a glove emphasise either protection or performance. There is often a trade-off between increased safety and performance capability when donning gloves. It has been determined that gloves which are fitted and comfortable for the worker may provide the best compromise between protective functions and decreased performance. This investigation aimed to assess the influence of glove fit on the performance attributes of industrial tasks, as well as on the responses of the human operator. Glove fit was analysed as 35 male participants donned three different glove sizes during each test, including a best-fitting glove, a glove one size smaller than best-fitting, and a glove one size larger than best-fitting. For each glove size, gloves of two differing materials were tested, namely nitrile and neoprene. A barehanded condition was also tested, totalling seven gloved/barehanded conditions for each test. The seven conditions were assessed in a laboratory setting in a battery of tests. This consisted of components of task performance, including maximum pulling and pushing force, maximum torque, precision of force, tactility, speed and accuracy and dexterity. The performance responses were recorded, as well as participants’ perceptual responses using the Rating of Perceived Exertion scale, and muscle activity. Six muscles were selected: Flexor Digitorum Superficialis, Flexor Pollicus Longus, Extensor Carpi Ulnaris, Extensor Carpi Radialis, Flexor Carpi Ulnaris and Flexor Carpi Radialis. The results revealed that glove fit does affect certain spects of performance, and influences human operator responses for selected task components. Furthermore, discrepancies were distinguished between orking barehanded and working with an optimally fitted glove. There was also a glove material effect established. Overall, it was found that muscle activity when exerting maximum force in a pushing and pulling direction was optimal with the nitrile glove material. Maximum torque performance was enhanced with the use of a best-fitting glove, as compared with an ill-fitting glove or barehanded work. Force precision was preferable when barehanded, as opposed to the tactility task which rendered optimal results with a best-fitting glove. The same was found for speed and accuracy results, as glove fit appeared to have no effect on performance, but performance was improved when participants were barehanded. Dexterity performance was the most conclusively influenced by the conditions, resulting in barehanded performance being optimal. However, should a glove be necessary for a given task, an optimally-fitted glove which is of a thinner material would be recommended. It is necessary to distinguish the performance components of a task within industry and select the most appropriate glove for optimal performance and the least risk of overexertion.

In the western world there is an issue in healthcare being created by an increasing number of people who experience disability. Whilst the reasons for these occurring are multiple, the common treatment to aid recovery from this condition is therapy that requires manual stimulation of the musculature form [sic] a therapist. Due to the physical demands that this process places on the therapist it is thought that a possible solution to meeting the increasing future demand for therapy is with developments in robotic technology. This thesis proposes and develops the design of a cable-driven glove to assist patients to grasp, this direction of design was chosen after a consultation with former patients found that this was the activity of upper limb motion that they felt was the most difficult to control after therapy. Their design requirements resulted in the creation of a lightweight glove that maximised the performance of the cable driven system through the use of a vacuum to secure the cable and use the joints of their body to control the flexion. This design resulted in the development of a first generation prototype that was assessed firstly by operating a 3D printed hand to grasp a collection of balls and cubes. After this the prototype was tested by unimpaired volunteers to provide feedback on the comfort and control they have when using the device, which was then compared to the findings from the initial consultation. This showed that the glove was successful in performing the intended motion and was considered comfortable (3.5/5) as well as providing them control (3.83/5). The device was used in a consultation with medical workers as well, who were impressed with the strength of the device, but highlighted improvements that could be made to refine it further.

Ausgehend von der These, Luftverkehr finde am Boden statt, entwickelt die am Institut für Kulturwissenschaft verteidigte Dissertation eine spezifische Geopolitik des Luftverkehrs. Der Luftverkehr wird dabei über seine Operationen am Boden und an Flughäfen untersucht. Der genaue Blick auf die technischen Details bei der Implementierung dieser Anlagen in machthistorisch entscheidenden Momenten des 20. Jahrhunderts ermöglicht eine Revision geopolitischen Denkens und eröffnet einen innovativen Zugang für eine Genealogie der Globalisierung. Die Dissertation analysiert die Bewegungen in der Luft auf ihre stets lokalen und immanent territorialen Dimensionen – und widerlegt so den vermeintlichen und häufig wiederholten Anspruch an den Luftverkehr, er sei das globale, raumvernichtende Verkehrssystem par excellence (Carl Schmitt, Paul Virilio, Martin Heidegger). Die Dissertation ist auch ein Beitrag zur Genealogie von Medientheorie, insofern sie unter Rückgriff auf Harold A. Innis die Übertragung nicht von Zeichen, sondern von Personen und Gütern zum Gegenstand hat. Historisch geht sie von der Kriegslogistik der USA im Zweiten Weltkrieg aus. Sie bezieht heterogene Quellen ein: politische Programme und Debatten, internationale Beziehungen; philosophische, juridische, ökonomische und urbanistische Diskurse; ingenieurstechnische Entwicklungen und militärische Doktrinen. Sie nimmt den Leser mit auf eine Reise über alle Meere und Kontinente mit Fokus auf Saudi-Arabien, Zentral- und Südafrika, Brasilien und den Nahen Osten, untersucht Ereignisse von den 1930er bis 1970er Jahren und endet mit einem Epilog zu den Anschlägen vom 9. September 2011.This dissertation develops a specific geopolitics of aviation, taking an original perspective as it starts with the assumption that air travel happens on the ground. The focus is on a thorough examination of the technical details for implementing the facilities of airports at moments decisive for the distribution of power in the 20th century. Geopolitical discourses are revised to enable an original understanding for the genealogy of globalisation. The dissertation analyses movements in the air with view on their immanent local and territorial dimensions. It breaks with the overcome understanding of aviation as a traffic system that is global and that destroys space as no other (Carl Schmitt, Paul Virilio, Martin Heidegger). The dissertation was disputed at the Institute for Cultural Studies. It is also a contribution to the genealogy of media theory, following in the footsteps of Harold A. Innis, as it focuses on the neglected transmission of goods and people instead of signs and codes. Starting point is the US military logistics in World War II. The heterogeneous material under review includes political programmes and debates; international relations; philosophical, juridical and economic discourses; urbanism, engineering and military doctrines. It takes the reader on a journey around the world, with focus on Saudi-Arabia, Central and Southern Africa, Brazil and the Near East, taking into account events from the 1930s to 1970s, and concluding with an epilogue on the events of 9/11.

Vast improvements in robotics and wireless communication have made teleoperated robots significantly more prevalent in industry, defense, and research. To help bridge the gap for these robots in the workplace, there has been a tremendous increase in research toward the development of biomimetic robotic hands that can simulate human operators. However, current methods of control are limited in scope and do not adequately represent human muscle memory and skills. The vision of this thesis is to provide a pathway for overcoming these limitations and open an opportunity for development and implementation of a cost effective methodology towards controlling a robotic hand.
The first chapter describes the experiments conducted using Flexpoint bend sensors in conjunction with a simple voltage divider to generate a cost-effective data glove that is significantly less expensive than the commercially available alternatives. The data glove was able to provide sensitivity of less than 0.1 degrees. The second chapter describes the molding process for embedding pressure sensors in silicone skin and data acquisition from them to control the robotic hand. The third chapter describes a method for parsing and observing the information from the data glove and translating the relevant control variables to the robotic hand. The fourth chapter focuses on the feasibility of the brain computer interfaces (BCI) and successfully demonstrates the implementation of a simple brain computer interface in controlling a robotic hand.Master of Science

Full textAbstract:
For over 30 years, the development and control of anthropomorphic robotic hands has been a highly popular sub-discipline in robotics research. Because the human hand is an extremely sophisticated system, both in its mechanical and sensory abilities, engineers have been fascinated with replicating these abilities in artificial systems. The applications of robotic hands typically fall under the categories of standalone testbed platforms, mostly to conduct research on manipulation, prosthetics, and robotic end effectors for larger systems. The teleoperation of robotic hands is another application with significant potential, where users can control a manipulator in real time to accomplish diverse tasks. In controlling a device that seeks to emulate the function of the human hand, it is intuitive to choose a human-machine interface (HMI) that will allow for the most intuitive control. Data gloves are the ideal HMI for this need, allowing a robotic hand to accurately mimic the human operator's natural movements. In this paper we present a combined review on the critical design aspects of data gloves and robotic hands. In literature, many of the proposed designs covering both these topical areas, robotic hand and data gloves, are cost prohibitive which limits their implementation for intended tasks. After reviewing the literature, new designs of robotic hand and data glove technology are also presented, introducing low cost solutions that can serve as accessible platforms for researchers, students, and engineers to further the development of teleoperative applications.Master of Science

Full textAbstract:
This thesis explores the field of robotic hand exoskeletons and their applications. These systems have emerged in popularity over the years, due to their potentials to advance the medical field as assistive and rehabilitation devices, and the field of virtual reality as haptic gloves. Although much progress has been made, hand exoskeletons are faced with several design challenges that are hard to overcome without having some tradeoffs. These challenges include: (1) the size and weight of the system, which can affect both the comfort of wearing it and its portability, (2) the ability to impose natural joint angle relationships among the user's fingers and thumb during grasping motions, (3) safety in terms of limiting the range of motions produce by the system to that of the natural human hand and ensuring the mechanical design does not cause harm or injury to the user during usage, (4) designing a device that is user friendly to use, and (5) the ability to effectively perform grasping motions and provide sensory feedback for the system to be applicable in various application fields.
In order to address these common issues of today's state-of-the-art hand exoskeleton systems, this thesis proposes a mechanism design for a novel hand exoskeleton and presents the integration of several prototypes. The proposed hand exoskeleton is designed to assist the user with grasping motions while maintaining a natural coupling relationship among the finger and thumb joints to resemble that of a normal human hand. The mechanism offers the advantage of being small-size and lightweight, making it ideal for prolong usage. Several applications are discussed to highlight the proposed hand exoskeleton functionalities in processing sensory information, such as position and interactive forces.MS

Full textAbstract:
L’objet de notre thèse est l’unité de l’œuvre de Péguy selon Hans Urs von Balthasar. Balthasar est le premier commentateur qui a tenté de relire tout l’itinéraire du poète à la lumière du petit autoportrait que le poète a laissé dans Un nouveau théologien. M. Fernand Laudet : « c’est par un approfondissement constant de notre cœur… que nous avons retrouvé la voie de chrétienté. » En prenant ce mot de « cœur » dans les différentes acceptions que l’écrivain lui a données, Balthasar a été capable de rassembler l’œuvre de Péguy de façon organique en une voûte qui a les Mystères pour clé. À la lumière des plus profondes intentions du cœur du jeune Péguy, Balthasar peut éclairer non seulement le rejet d’un certain christianisme augustinien et la décision de se placer résolument au cœur du socialisme, mais encore le retour progressif au catholicisme. En retrouvant la foi, Péguy entame cependant un approfondissement ultérieur : il médite le mystère même du cœur chrétien et pénètre enfin le cœur du Père. Notre travail a voulu présenter une lecture très originale de l’itinéraire de Péguy. La pertinence de cette lecture est prouvée, entre autres choses, par sa capacité à intégrer les plus grandes interprétations de Péguy qui l’ont précédée et même suivieThe theme of the present dissertation is the unity of the work of Charles Péguy in the interpretation of Hans Urs von Balthasar. Balthasar is the first commentator who has attempted to re-read the whole trajectory of Péguy’s life and work in light of the brief self-portrait that the poet offers us in Un nouveau théologien. M. Fernand Laudet. “It was,” Péguy writes there, “a constant deepening of our heart . . . that lead us to discover the path of Christendom.” Meditating on the various meanings of the word “heart” in the poet’s thought, Balthasar is able to show his work rising into an organic edifice with the Mysteries as its keystone. He shows how not only Péguy’s repudiation of an Augustinian Christianity and his resolute embrace of the heart of socialism, but his eventual return to Catholicism make sense only in light of what were from the very beginning his heart’s deepest intentions. But Péguy’s rediscovery of faith meant also the entry into a new deepening of the heart: the contemplation of the mystery of the Christian heart and at last of the Father’s heart. This dissertation seeks to present Balthasar’s original reading of Péguy’s trajectory and, at the same time, to show its fecundity, which is demonstrated by, among other things, its capacity to integrate the major readings of Péguy produced both before and after Balthasar’s own work on the poet

The rehabilitation process usually contains everyday tasks to evaluate the patient’s capability and the tools for this part of the rehabilitation process are few. The challenges will be to find a suitable sensor for the application and how to implement the sensor in a versatile prototype with direct feedback for the user. To solve this problem, research will be conducted on different pressure sensor types to determine the most suitable one for this implementation. The resulting prototype is utilizing a force sensing resistor (FSR) mounted on a glove together with a module that presents direct feedback to the patient and caretaker. The glove has pressure sensors in each fingertip to detect the applied force for each individual finger when the patient grips an object. To present the feedback, a visual interface is created in the form of a hand with a LED for each finger, which provides direct visual feedback and a display to present numerical data.Denna avhandling undersöker hur trycksensorer kan användas vid rehabilitering av patienter med försvagad handstyrka. Rehabiliteringsprocessen innehåller vanligtvis vardagliga uppgifter för att utvärdera patientens förmåga och nuvarande hjälpmedel är få. Utmaningarna är att hitta en lämplig sensor för applikationen och hur man kan implementera sensorn i en mångsidig prototyp med en direkt återkoppling för användaren. För att lösa detta problem kommer forskning att genomföras på olika typer av trycksensorer. Detta görs för att kunna bestämma den mest lämpade sensortypen för denna implementering. Den resulterande prototypen består av en handske med kraft känsliga resistorer (FSR) och en separat modul som ger direkt återkoppling till patienten och vårdtagaren. Handsken har en sensor i varje fingertopp för att detektera applicerad kraft för varje enskilt finger när patienten greppar ett föremål. För att presentera data från sensorerna skapas ett visuellt gränssnitt. Gränssnittet är i form av en hand med lysdioder i varje finger för direkt återkoppling och en bildskärm för att presentera numeriska data.

Full textAbstract:
Rheumatoid arthritis (RA) is an autoimmune disease affecting nearly 1% of the world’s population with symptoms such as inflammation, pain, and reduced strength [1]. Physicians and scientists work to develop pharmaceuticals and medical devices aimed at decreasing the symptoms associated with RA to better the lives of those affected. One of the most recent developments is the addition of thermal therapy gloves to the array of upper limb orthoses available to patients with RA. It was hypothesized that this study will show that orthoses in the form of thermal therapy gloves are beneficial to the patients by reducing symptoms such as pain and allowing them an increased range of motion and overall hand functionality. Patients in stage 2 were recruited and asked to first complete a personal history survey including the Health Assessment Questionnaire (HAQ) [2] and Pain Catastrophizing Scale (PCS) [3]. Range of motion tasks and the Arthritis Hand Function Test (AHFT) [4] were completed to determine the effect of two thermal therapy gloves on the range of motion and activities of daily living. The data suggests that the use of thermal therapy orthoses does provide a psychological advantage in the form of reduced perceived pain along with the advantage of being able to complete activities previously believed to be impossible for participants to complete. Additionally, it is suggested that heat-generating material be used in the manufacturing of these orthoses in order to remove the need for any further design modifications. Future studies should be conducted in order to analyze the long-term effects of these orthoses along with the possible psychological benefits of their use.

Full textAbstract:
Optical pose recognition of the hand is an extremely attractive method for user-computer interaction in many applications. The image of a hand in the frame of a video camera is processed and the pose it is making, its current finger configuration, is detected. Often combined with position tracking, it allows for a very natural way of giving commands. Furthermore, it alleviates the use of sometimes cumbersome pieces of hardware. Within immersive virtual reality systems, the liberty of movement of the commanding hand requires extra considerations not normally dealt with by typical optical hand posture recognition interfaces for desktop system applications. This research proposes an artificial neural network approach to the recognition of hand postures. The optical capture inside an immersive virtual reality workspace and the extraction of features of this hand are facilitated by the use of a specially coded color glove.

Full textAbstract:
Grasping, the skill to hold objects and tools while doing in-hand manipulation, still is in many cases an unsolvable problem for robotics, but a natural act for humans. An efficient grasping requires not only human-like robotic hands with articulated fingers but also tactile, force, and kinesthetic sensors for the precise control of the forces and motions exerted during the manipulation.
As a fully autonomous robotic dexterous manipulation is too difficult to develop for changing and unstructured environments, an alternative approach is to combine the low-level robot computer control with the higher-level perception and task planning abilities of a human operator equipped with an adequate human-computer interface (HCI).
This thesis presents theoretical and experimental contributions to the development of an upgraded haptic-enabled anthropomorphic Ring Ada dexterous robotic hand and a biology-inspired synergistic real-time control system for teleoperated grasping of different objects using a CyberTouch HCI data glove. A fuzzy logic controller module was developed to efficiently control the underactuated Ring Ada’ robotic hand during grasping. A machine learning classification system was developed to recognize grasped objects.
Experiments have convincingly demonstrated that our novel Ring Ada robotic hand equipped with kinematic position sensors and touch sensors is able to efficiently grasp different lightweight objects through teleoperation.

The most common forms of Human Computer Interaction (HCI) devices these dayslike the keyboard, mouse and touch interfaces, are limited to working on atwo-dimensional (2-D) surface, and thus do not provide complete freedom ofaccessibility using our hands. With the vast number of gestures a hand can perform,including the different combinations of motion of fingers, wrist and elbow, we canmake accessibility and interaction with the digital environment much more simplified,without restrictions to the physical surface. Fortunately, this is possible due to theadvancements of Microelectromechanical systems (MEMS) manufacturing of sensors,reducing the size of a sensor to the size of a fingernail.In this thesis we document the design and development of a smart glove systemcomprising of Inertial Measurement Units (IMU) sensors that recognize handactivity/gestures using combinations of neural networks and deep learning techniquessuch as Long Short-Term Memory (LSTM) and Convolutional Neural Network(CNN). This peripheral device is named as the Gauntlet-X1, X1 to denote thecurrent prototype version of the device. The system captures IMU data and interfaceswith the host server. In order to demonstrate this prototype as a proof of concept,we integrate to Android mobile applications based on 3-D interactivity like theAmerican Sign Language(ASL), Augmented Reality (AR)/Virtual Reality (VR)applications and can be extended to further the use of HCI technology.

In this paper, the research focused on the development of a hand rehabilitation device which could perform extension, opposition and reposition movements. Firstly, the anatomy of the hand is analyzed and studied to understand where the problem resides; since the mechanism will be applied to post-stroke patients, it is necessary to comprehend the structure and the articulations of the hand, the muscles involved in the mentioned movements and how a healthy hand works. Then, the causes of the problem are studied, what are the consequences on the hand and how to solve every issue. Brunnström Approach is taken as reference for the rehabilitation therapy steps. After the performance target is defined and which function has the priority, a brief research on the state of the art is made. Six different devices are analyzed, taking into account their strengths and weaknesses, evaluating them and trying to find possible lacks to solve.
An evaluation of possible solutions is done, in order to find the optimal solution for the problem. Various types of actuation and structure of the mechanism are considered.
Defined which are the best choices between the ones proposed, the next step is to design a first prototype with the purpose of bringing together the solutions selected. The CAD used is PTC Creo Parametric.
Once the first prototype was designed, it was partially printed with 3D technique (additive manufacturing) and tested; tests were made on the actuation and on the device to evaluated its efficacy. The results are visible in this paper.
Finally, a conclusion is discussed with a short resume of the experiments made and the results obtained. Furthermore, remaining problems and future works are analyzed and debated.

Résumé : Dans la sclérodermie systémique (ScS), les contractures aux mains, pour lesquelles il n'existe aucun traitement prouvé, sont courantes et associées à de l'incapacité de la main, globale et au travail. Toutefois, quelques études sur les effets d'interventions comprenant des techniques manuelles ont montré des résultats prometteurs. Ainsi, le but de l'étude était d'explorer les effets d’un traitement ostéopathique sur la fonction de la main, des symptômes globaux de la maladie et le statut fonctionnel de personnes atteintes de ScS. Une série d'études à cas uniques (A[indice inférieur 1]-B-A[indice inférieur 2]) fut réalisée. Six participantes atteintes de ScS ont été recrutées parmi la cohorte du Groupe de recherche canadien sur la sclérodermie à deux sites (Hôpital général juif de Montréal et Centre hospitalier universitaire de Sherbrooke). Les participantes ont reçu neuf séances hebdomadaires d’ostéopathie semi-standardisées, ciblées sur les membres supérieurs, le thorax et la base du crâne. Des mesures répétées pendant les trois phases de l'étude ont été prises à une fréquence bihebdomadaire pour la raideur aux mains (RM) et les symptômes de douleur, dyspnée et fatigue; et hebdomadaire pour l'amplitude de mouvement des doigts (AMD), la fonction de la main (FM) et l'incapacité globale (IG). L'épaisseur/rigidité de la peau main/avant-bras (ÉPMA), l'incapacité au travail (IT) et la qualité de vie reliée à la santé (QVS) ont été mesurées à trois temps (avant et après l'intervention, ainsi qu'au suivi à un mois). Les variables à mesures répétées ont été représentées sur des graphiques linéaires soumis à des analyses visuelles, complétées du test Sheward's two Standard Deviation Band. Les différences ont été calculées pour les variables mesurées à trois temps. Toutes les participantes (n=6) ont montré une amélioration des variables reliées à la fonction manuelle (RM, AMD et FM), sauf pour l'ÉPMA (n=4). La majorité des participantes ont montré une amélioration des symptômes (douleur n=6, fatigue n=4 et dyspnée n=3/4) et des variables reliées au statut fonctionnel (IG n=5/5, IT n=4, score résumé physique n=6 et mental n=4 de la QVS). La plupart des effets se sont maintenus au suivi à un mois. Lorsque la comparaison était possible, presque toutes les améliorations observées ont été supérieures aux différences minimales cliniquement importantes suggérées pour cette population. Ces résultats suggèrent que l'ostéopathie pourrait être efficace pour réduire l'incapacité découlant des contractures aux mains de personnes souffrant de ScS, et devraient être vérifiés dans un essai clinique randomisé. // Abstract : In systemic sclerosis (SSc), hand contractures are common and associated with hand, global and work disability. There are no known effective treatments, although there have been a few promising studies with manual therapies. Our aim was to explore the effects of osteopathy on hand function, disease symptoms and functional status in SSc patients. A series of single case studies (A[subscript 1]-B-A[subscript 2] was undertaken. Six female SSc patients with hand contractures were recruited among subjects enrolled in the Canadian Scleroderma Research Group cohort at 2 sites (Jewish General Hospital, Montreal and Centre hospitalier universitaire de Sherbrooke, Sherbrooke). Participants received 9 weekly semi-standardized sessions of osteopathy targetted on upper limbs, thorax and cranial base. Repeated measures were taken during the three phases of the study, twice a week for hand stiffness and disease symptoms of pain, dyspnea and fatigue; and once a week for range of motion of fingers, hand disability and global disability. Upper limbs skin score, work disability and health-related quality of life were measured at baseline, after treatments and at 1-month follow-up. Data for each variable with repeated measures were represented on simple line graphs and visually interpreted, completed by the Sheward's two Standard Deviation Band test. Differences were calculated for variables measured at 3 time points. All participants (n=6) showed improvement in variables related to hand function (hand stiffness, range of motion of fingers and hand disability), except for upper limbs skin score (n=4). The majority of participants showed improvement in disease symptoms (pain n=6, fatigue n=4, et dyspnea n=3/4) as well as variables related to functional status (global disability n=5/5, work disability n=4, physical n=6 and mental n=4 component summary of health-related quality of life). Most improvements were maintained at 4 week follow up. When the comparison was possible, almost all observed improvements were higher than the minimal clinically important differences suggested for this population. These findings suggest that osteopathy may be effective in reducing disability from hand contractures in SSc. A randomized controlled trial is needed to confirm these results.

Full textAbstract:
This paper uses a quantitative content analysis informed by a critical realist framework to study the patterns of international political economy discourse prevalence within research articles concerning free trade. Once categorized, there are observable differences in the extent to which articles in the different categories address other discourses. Analyzing these patterns using concepts from discourse theory, we suggest that the liberal discourse constitutes a regime of truth to which the other discourses must relate. It is also found that articles published in higher ranking journals are less likely to address other discourses. We argue that this could be explained as being an effect of the larger readership of those journals.

Full textAbstract:
Doctor of Philosophy (PhD)With improvements in actuation technology and sensory systems, it is becoming increasingly feasible to create powered exoskeletal garments that can assist with the movement of human limbs. This class of robotics referred to as human-machine interfaces will one day be used for the rehabilitation of paralysed, damaged or weak upper and lower extremities. The focus of this project was the development of an exoskeletal interface for the rehabilitation of the hands. A novel sensor was designed for use in such a device. The sensor uses simple optical mechanisms centred on a spring to measure force and position simultaneously. In addition, the sensor introduces an elastic element between the actuator and its corresponding hand joint. This will allow series elastic actuation (SEA) to improve control and safely of the system. The Hand Rehabilitation Device requires multiple actuators. To stay within volume and weight constraints, it is therefore imperative to reduce the size, mass and efficiency of each actuator without losing power. A method was devised that allows small efficient actuating subunits to work together and produce a combined collective output. This work summation method was successfully implemented with Shape Memory Alloy (SMA) based actuators. The actuation, sensory, control system and human-machine interface concepts proposed were evaluated together using a single-joint electromechanical harness. This experimental setup was used with volunteer subjects to assess the potentials of a full-hand device to be used for therapy, assessment and function of the hand. The Rehabilitation Glove aims to bring significant new benefits for improving hand function, an important aspect of human independence. Furthermore, the developments in this project may one day be used for other parts of the body helping bring human-machine interface technology into the fields of rehabilitation and therapy.

Full textAbstract:
The usage of signatures for authentication is widely accepted, and remains one of the most familiar biometric in our society. Efforts to digitalise and automate the verification of these signatures are hot topics in the field of Machine Learning, and a plethora of different tools and methods have been developed and adapted for this purpose. The intention of this report is to study the authentication of handwritten signatures on digital whiteboards, and how to most effectively set up a dual verification system based on Hidden Markov models (HMMs) and global aggregate features such as average speed. The aim is to gauge which features are Suitable for determining that a signature is in fact genuine Suitable for rejecting forgeries Unsuitable for gauging the authenticity of a signature all together In addition, we take a look at the configuration of the HMMs themselves, in order to find good configurations for The number of components used in the model What type of covariance to use The best threshold to draw the line between a genuine signature and a forgery For the research, we collected a total of 200 signatures and 400 forgeries, gathered from 10 different people on digital whiteboards. We concluded that the best configurations of our HMMs had 11 components, used a full covariance model, and observed about five features, where pressure, angle and speed were the most important. Among the global features, we discarded 11 out of 35 due to either strong correlation with other features, or contained too little discriminatory information. The strongest global features were the ones pertaining to speed, acceleration, direction, and curvature. Using the combined verification we obtained an EER of 7 %, which is in the typical range of contemporary studies. We conclude that the best way to combine global feature verification with local HMM verification is to perform both separately, and only accept signatures that are admissible by both, with a tolerance level for the global and local verifications of 1.2 and 2.5 standard deviations, respectively.Användandet av signaturer för autentisering är allmänt accepterat, och är fortfarande den mest använda biometriken i vårt samhälle. Arbetet med att digitalisera och automatisera verifieringen av dessa signaturer är ett populärt ämne inom maskininlärning, och en uppsjö av olika verktyg och metoder har utvecklats och anpassats för detta ändamål. Avsikten med denna studie är att bestämma hur man mest framgångsrikt kan inrätta ett verifikationssystem för handskrivna signatures på digitala whiteboards baserat på dolda Markovmodeller (HMMs) och globalt aggregerade attribut. Syftet är att bedöma vilka features som är Lämpliga för att bestämma huruvida en signatur är äkta Lämpliga för att avvisa förfalskningar Olämpliga för att mäta äktheten hos en signatur över huvud taget Utöver detta studerar vi HMM-konfigurationen själv, i syfte att hitta bra konfigurationer för Antalet komponenter som används i modellen Vilken typ av kovarians som ger bäst resultat Det bästa tröskelvärdet vid vilken att dra gränsen för huruvida en signatur är äkta eller förfalskad För forskningen samlade vi totalt in 200 signaturer och 400 förfalskningar från 10 olika personer med hjälp av digitala whiteboards. Vi drog slutsatsen att de bästa konfigurationerna hade 11 komponenter, använde komplett kovarians, och använde cirka fem features, där tryck, vinkel och hastighet var det viktigaste. Bland våra globala features kastade vi 11 av 35 på grund av att de antingen korrelerade för starkt med andra features, eller på grund av att de innehöll för lite information för att utröna huruvida en signatur var äkta eller ej. Våra bästa globala features var de som hänförde sig till hastighet, acceleration, riktning och krökning. Genom att använda den kombinerade verifieraren fick vi en EER på 7 %, vilket är i linje med liknande studier. Vi drog även slutsatsen att det bästa sättet att kombinera global verifiering med lokal HMM-verifiering är att utföra dem separat och endast acceptera signaturer som godkänns av bägge två. Den bästa toleransnivån för den globala och lokala verifieraren var 1,2 och 2,5 standardavvikelser, respektive.

Introdução: A inspeção e o acondicionamento dos instrumentais cirúrgicos limpos em caixas e bandejas, implicam na manipulação desses produtos. Na prática, é possível observar grande descompasso entre o cuidado dispensado a essa etapa, quando comparado ao rigor exigido para remoção completa de contaminantes por meio da limpeza. A falta de consenso quanto ao uso de luvas nessa etapa do processo chama a atenção e não se sabe se esse detalhe repercute na qualidade final do material quanto à segurança para o paciente cirúrgico. Objetivos: Determinar se há diferenças na resposta citotóxica relacionada ao uso de distintos tipos de luvas e das mãos nuas na inspeção e preparo do instrumental cirúrgico limpo e avaliar a carga microbiológica de instrumentais cirúrgicos preparados sem luvas e sua repercussão na esterilização. Método: Esta pesquisa realizou um experimento laboratorial com abordagem pragmática, utilizando cânulas de oftalmologia que foram manipuladas com diferentes tipos de luvas e com as mãos nuas. Posteriormente, o teste de citotoxicidade foi realizado por meio da difusão em ágar. Pinças anatômicas também fizeram parte da amostra para a análise exploratória microbiológica, após serem manipuladas sem luvas, e posteriormente, submetidas à avaliação de sua esterilidade, após autoclavação. Resultados: Nenhuma das amostras de cânulas de oftalmologia manipuladas por diferentes tipos de luvas e por mãos nuas apresentou efeito citotóxico.Todas as culturas microbiológicas das pinças anatômicas manipuladas sem luvas apresentaram crescimento de microrganismos aeróbios e anaeróbios, embora nenhum microrganismo tenha sido recuperado após a autoclavação. Conclusão: Não houve evidências de diferenças de resposta citotóxica relacionada ao uso de diferentes tipos de luvas e das mãos nuas na manipulação do instrumental cirúrgico limpo que sinalizasse risco de iatrogenia. Ressalta-se que o uso de luvas implica aumento dos custos do processo e na geração de resíduos, além do potencial risco alergênico ao látex. Esta pesquisa teve como relevância subsidiar a elaboração de protocolos para a etapa de preparo de instrumentais cirúrgicos limposIntroduction: The aim of reprocessing surgical instruments is to provide instruments that are clean, in good working condition and ultimately sterile thus ensuring patient safety. During instrument there is no agreement about the necessity for glove use. Therefore, there is little reason for employees to wear gloves to protect themselves from possible residual contaminants on cleaned instruments that had previously been used during clean or sterile surgery. On the other hand, the use of the gloves to handle surgical instruments during preparation increases medical waste, increases medical costs and could increase the prevalence of glove allergies in staff. Aim: In this study we investigated the risk posed to patients from staff wearing different types of gloves or no gloves to prepare surgical kits. Method: Five cleaned ophtalmic cannulas were handled using different kinds of gloves and with bare hands, package and steam sterilized. An in vitro cytotoxicity test was conducted, using the agar diffusion test. Microbiological tests were conducted as well, in samples handled with bare hands. Results: All test samples showed the same mild reactivity (grade 2) indicating that handling instruments with gloves or bare hands did not leave any residual toxic products on the instrument surface. Conclusion: We found no difference in the iatrogenic risk to patients of either increased toxicity or increased risk of microbial contamination if surgical instruments are prepared with or without gloves. However, the use of gloves has some inherent disadvantages, such as the risk of latex sensitization of the workers and increased medical costs due to purchase and waste disposal

Neste trabalho, descreve-se a implementação de uma prótese de mão biônica de baixo custo, constituída por um mecanismo com dezesseis graus de liberdade, cinco dedos articulados individualmente, acionados por tendões mecânicos. Sua estrutura foi fabricada em impressora 3D. Para o interfaceamento homem-máquina foi desenvolvido um shield, que realiza a aquisição de sinais eletromiográficos, com dois canais, armazenamento em cartão SD e um sistema eletrônico capaz de gerar um banco de dados com movimentos realizados pela mão humana. Foi utilizada a plataforma Arduino para processamento e programação. O sistema contém um aplicativo com protocolo de acionamento programável e inserção de movimentos, proporcionando independência ao usuário. Foram realizados testes nos quais o sistema implementado executou movimentos, após armazenar vários movimentos funcionais da mão. Isso foi possível devido ao desenvolvimento de um algoritmo capaz de reconhecer, quantificar e armazenar os sinais produzidos pelas contrações dos músculos. A prótese ativa implementada funcionou adequadamente para paciente com deformidade congênita e para paciente amputado. O valor total dos componentes mecânicos e eletrônicos necessários para implementar a prótese ativa e a utilização de hardwares e softwares livres contribuem para que o custo do dispositivo seja reduzido.
This paper describes the implementation a low cost hand prosthesis, a mechanism constituted by sixteen degrees of freedom, five articulated fingers individually, driven by mechanical tendons. Its structure was made in a 3D printer. For the man-machine interfacing, a shield was developed which performs the acquisition of electromyographic signals, with two channels, SD card storage and an electronic system able to generate a database of movements made by the human hand. The Arduino platform was used for processing and programming. The system contains an app with a programmable drive and insertion movements protocol, providing independence to the user. Tests were conducted in which the implemented system performed movements, after storing various functional hand movements. This was possible due to the development of an algorithm capable of recognizing, quantifying and storing the signals produced by muscle contractions. The implemented active prosthesis worked well for patients with congenital deformity and amputee. The total value of the mechanical and electronic components required to implement the active prosthesis and the use of free hardware and software contribute to the low cost of the device.
