Analysis to Determine Optimum Strain Gauge Locations for SENSEWHEEL new

T. Suzuki[1], C. Holloway[1], S. Taylor[1]
[1]University College London, London, UK

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx ... En Savoir Plus

Coupled Heat and Mass Transfer Model to Simulate Hygrothermal Behavior of Bio-Based Materials

M. Asli [1], F. Brachelet [1], A. Chauchois [1], E. Antczak [1]
[1] Université d'Artois, Béthune, France

This poster presents a numerical modeling approach for hygrothermal behavior of bio-based materials. The mathematical model describes the heat and moisture transfer through a wall of bio-based materials. The studied wall is subjected to both convective heat transfer and moisture flux ...

Development of a Microfluidic-Based Electrochemical Cell for Analyzing Bacterial Biofilms

I. Claydon [1], J. Turner [1], B. Sammakia [1],
[1] Binghamton University, Binghamton, NY, USA

The ubiquitous nature of biofilms has led to a growing need to be able to detect, control, and maintain or remove them. Therefore a robust testing platform that allows for multiple analytical techniques is required to better understand their multitude of properties. The development of ... En Savoir Plus

Modeling of the Singlet Oxygen Distribution in Photofrin-Photodynamic Therapy of the Plural Cavity

R. Penjweini [1], T. C. Zhu [1], M. M. Kim [1],
[1] Department of Radiation Oncology, School of Medicine, University of Pennsylvania, Philadelphia, PA, USA

Photofrin-mediated photodynamic therapy (PDT) is used after surgical resection at the University of Pennsylvania to treat the microscopic disease for malignant pleural mesothelioma and to increase survival rate. When Photofrin is exposed to laser light at 630 nm in well-oxygenated ... En Savoir Plus

Fluid Flow Behavior in Steady and Transient Force Medical Injection Systems

E. Gutierrez-Miravete [1], T. Langley [2],
[1] Rensselaer Polytechnic Institute - Hartford, Hartford, CT, USA
[2] Rensselaer Polytechnic Institute, Troy, NY, USA

Syringes were first conceptualized in 1650, but were invented in 1853 by Dr. Alexander Wood. As of 2011, nearly 8 billion syringes are used each year in the United States for medical purposes (not including veterinary services). These syringes are used for diseases like diabetes, ...

A Heat Transfer Analysis of the Cochlea During Magnetically-guided Cochlear Implant Surgery

F. Esmailie [1], M. Francoeur [1], T. A. Ameel [1], ,
[1] Department of Mechanical Engineering, University of Utah, Salt Lake City, UT, USA

Approximately 450,000 people worldwide suffering from hearing problems use cochlear implants (http://www.cochlear.com/au/home/connect/cochlear-hearing-ambassador, June 12, 2018). Manual insertion of the cochlear implant during surgery can potentially damage the delicate tissues within ... En Savoir Plus

Model of the Cardiac Defibrillation Induced by an Implantable Defibrillator in the Body
