Spatially Distributed Tactile Feedback For Kinesthetic Motion Guidance, Pulkit Kapur, Mallory Jensen, Laurel J. Buxbaum, Steven A. Jax, Katherine J. Kuchenbecker

Departmental Papers (MEAM)

Apraxic stroke patients need to perform repetitive arm movements to regain motor functionality, but they struggle to process the visual feedback provided by typical virtual rehabilitation systems. Instead, we imagine a low cost sleeve that can measure the movement of the upper limb and provide tactile feedback at key locations. The feedback provided by the tactors should guide the patient through a series of desired movements by allowing him or her to feel limb configuration errors at each instant in time. After discussing the relevant motion capture and actuator options, this paper describes the design and programming of our current ...


Shape And Pose Recovery Of Novel Objects Using Three Images From A Monocular Camera In An Eye-In-Hand Configuration, Steven C. Colbert 2010 University of South Florida

Shape And Pose Recovery Of Novel Objects Using Three Images From A Monocular Camera In An Eye-In-Hand Configuration, Steven C. Colbert

Graduate Theses and Dissertations

Knowing the shape and pose of objects of interest is critical information when planning robotic grasping and manipulation maneuvers. The ability to recover this information from objects for which the system has no prior knowledge is a valuable behavior for an autonomous or semiautonomous robot. This work develops and presents an algorithm for the shape and pose recovery of unknown objects using no a priori information. Using a monocular camera in an eye-in-hand configuration, three images of the object of interest are captured from three disparate viewing directions. Machine vision techniques are employed to process these images into silhouettes. The ...


Multidisciplinary Engineering Systems 2nd And 3rd Year College-Wide Courses, Kevin Craig, Mark L. Nagurka 2010 Marquette University

Multidisciplinary Engineering Systems 2nd And 3rd Year College-Wide Courses, Kevin Craig, Mark L. Nagurka

Mechanical Engineering Faculty Research and Publications

Undergraduate engineering education today is ineffective in preparing students for multidisciplinary system integration and optimization - exactly what is needed by companies to become innovative and gain a competitive advantage in this global economy. While there is some movement in engineering education to change that, this change is not easy, as it involves a cultural change from the silo approach to a holistic approach. The ABET-required senior capstone multidisciplinary design course too often becomes a design-build-test exercise with the emphasis on just getting something done. Students rarely break out of their disciplinary comfort zone and thus fail to experience true multidisciplinary ...

Optimisation Acoustique De Paroi Par Algorithme Génétique Et Influence De L’Habillage Par Une Couche Poreuse, Nicolas Dauchez, Olivier Doutres, Jean-Michel Genevaux, Jean-Christophe Le Roux 2010 École de technologie supérieure (ETS)

Optimisation Acoustique De Paroi Par Algorithme Génétique Et Influence De L’Habillage Par Une Couche Poreuse, Nicolas Dauchez, Olivier Doutres, Jean-Michel Genevaux, Jean-Christophe Le Roux

Olivier Doutres Ph.D.

L’amélioration du confort acoustique dans les habitacles passe en particulier par l’optimisation de la transparence acoustique de parois simple ou double au moyen de matériaux viscoélastiques et poreux. Une méthode d’optimisation de paroi basée sur un algorithme génétique couplé à un calcul par matrices de transfert est présentée. Cette technique permet une exploitation efficace des itérations précédentes sans coût de calcul supplémentaire. Les résultats obtenus pour une simple et une double paroi sont analysés. Dans un deuxième temps, l’influence d’un habillage poreux est présenté en fonction de la nature du squelette : mousse polymère ou fibreux ...


Mesure Des Propriétés Mécaniques Des Matériaux Poreux À L’Aide D’Un Transducteur Électrodynamique Sans Fer, Nicolas Dauchez, Olivier Doutres, Jean-Michel Génevaux, Guy Lemarquand, Sylvain Mezil 2010 École de technologie supérieure (ETS)

Mesure Des Propriétés Mécaniques Des Matériaux Poreux À L’Aide D’Un Transducteur Électrodynamique Sans Fer, Nicolas Dauchez, Olivier Doutres, Jean-Michel Génevaux, Guy Lemarquand, Sylvain Mezil

Olivier Doutres Ph.D.

Un banc de mesure des propriétés mécaniques des matériaux poreux est présenté. Il permet d'étendre les méthodes quasistatiques basées sur la compression d'un échantillon vers les hautes fréquences. Les méthodes quasistatiques sont limitées en fréquence (< 100 Hz) parce qu'elles négligent les éléments inertiels et le couplage avec l'air ambiant. Dans la méthode présentée, l'échantillon est placé dans une cavité étanche pour limiter l'effet de l'air ambiant et ainsi permettre une meilleure estimation du facteur de perte. Un transducteur électrodynamique a été conçu spécifiquement pour permettre une excitation sur une large gamme de fréquence : les premiers modes de l'équipage mobile sont au dela de 5 kHz. De plus, son architecture sans fer et sans suspension viscoélastique permet de l'utiliser comme capteur par le biais de son impédance électrique. L'impédance mécanique de l'échantillon est obtenue en inversant le modèle électromécanique du transducteur et les propriétés viscoélastiques - module d'Young et facteur de perte - sont obtenues par recalage d'un modèle analytique utilisant la théorie de Biot-Allard. Les résultats sont présentés pour une mousse polymère à cellule ouvertes. Le calcul des incertitudes montre que la méthode permet une bonne estimation jusque 500 Hz et permet de définir les conditions d'extension de la plage de fréquence.


Influence Of Ni Nanoparticle On The Morphology And Growth Of Interfacial Intermetallic Compounds Between, 2010 SelectedWorks

Influence Of Ni Nanoparticle On The Morphology And Growth Of Interfacial Intermetallic Compounds Between

A.S. Md Abdul Haseeb

TiO2 thin films were deposited on unheated and heated glass substrates at an elevated sputtering pressure of 3 Pa by radio frequency (RF) reactive magnetron sputtering. TiO2 films deposited at room temperature were annealed in air for 1 h at various temperatures ranging from 300 to 600 °C. The structural and optical properties of the thin films were investigated using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and ultraviolet-visible-near infrared (UV-VIS-NIR) spectrophotometry. XRD results show that as-grown and post-annealed TiO2 films have anatase crystal structure. Higher substrate and annealing temperatures result in a slight increase of crystallinity. TiO2 ...

A Simple Technique For Surface Area Determination Through Supercritical Co2 Adsorption, Mahmud Sudibandriyo

Makara Journal of Technology

The measurement of specific surface area of porous materials has long been important in physical sciences and is currently growing in importance in applied and environmental science. Numerous systems have been developed for surface area measurement by gas adsorption. Commercial systems are available which can measure a wide range of absolute surface area with relative ease. However, their cost is often prohibitive. In this study, an inexpensive apparatus for surface area measurement has been set up to be used for measuring supercritical adsorption of CO2. The Ono-Kondo Lattice model was used to represent the adsorption isotherm and to determine the ...

Makara Journal of Technology

Software Design of Mobile Antenna for Auto Satellite Tracking Using Modem Correction and Elevation Azimuth Method. Pointing accuracy is important in satellite communication. Because the satellite’s distance to the surface of the earth's satellite is so huge, 1 degree of pointing error will make the antenna unable to send data to satellites. To overcome this, the auto-tracking satellite controller is made. This system uses a microcontroller as the controller, with the GPS as the location indicator of the antenna, a digital compass as the beginning of antenna pointing direction, a rotary encoder as azimuth and elevation censor, and ...

Ontology-Based Automatic Classification For News Articles In Indonesian Language, Prajna Wira Basnur, Dana Indra Sensuse

Makara Journal of Technology

Ontology-Based Automatic Classification for News Articles in Indonesian Language. Searching specific information will be difficult if relying only on query. Choosing less specific queries will result in a lot of irrelevant information fetched by the system. One of the most successful ways to overcome this problem is to perform document classification based on the topic. There are many methods that can be used to conduct such a classification, such as using statistical and machine learning approaches. However, those document classification methods require training the data or learning the documents. In this study, the authors attempted to classify documents using a ...

Particle Filter With Binary Gaussian Weighting And Support Vector Machine For Human Pose Interpretation, Indah Agustien, Muhammad Rahmat Widyanto, Sukmawati Nur Endah, Tarzan Basaruddin

Makara Journal of Technology

This paper proposes human pose interpretation using particle filter (PF) with Binary Gaussian Weighting and support vector machine (SVM). In the proposed system, particle filter is used to track a human object, then this human object is skeletonized using thinning algorithm and classified using SVM. The classification is to identify human pose, whether it is normal or abnormal behavior. Here particle filter is modified through weight calculation using Gaussian distribution to reduce the computational time. The modified particle filter consists of four main phases. First, particles are generated to predict target’s location. Second, the weight of certain particles is ...

On The Effective Elastic Properties Of Macroscopically Isotropic Media Containing Randomly Dispersed Spherical Particles, D. Cojocaru, Anette M. Karlsson

Mechanical Engineering Faculty Publications

computational scheme for estimating the effective elastic properties of a particle reinforced matrix is investigated. The randomly distributed same-sized spherical particles are assumed to result in a composite material that is macroscopically isotropic. The scheme results in a computational efficient method to establish the correct bulk and shear moduli by representing the three-dimensional (3D) structure in a two-dimensional configuration. To this end, the statistically equivalent area fraction is defined in this work, which depends on two parameters: the particle volume fraction and the number of particles in the 3D volume element. We suggest that using the statistically equivalent area fraction ...
