Micro-Bathymetric Mapping Using Acoustic Range Images, Christopher Roman, Hanumant Singh Oct 2004

Micro-Bathymetric Mapping Using Acoustic Range Images, Christopher Roman, Hanumant Singh

Christopher N. Roman

This work focuses on the creation of high resolution micro-bathymetric maps using a high frequency pencil beam sonar. These maps typically cover areas of 10's to 100's of square meters. Data is collected using a sonar mounted to an underwater vehicle that can be positioned at discrete locations on the sea floor or flown in a survey pattern above the bottom. Specifically, we are focused on improving the accuracy of these terrain maps by merging sonar pings taken from multiple vantage points over the same location. This requires the adaption of data registration techniques to handle errors related to the …

Development And Analysis Of A Software Package To Quantify In Vivo Polyethylene Wear After Total Hip Arthroplasty, Allison Kinney, Catherine Ambrose Oct 2004

Development And Analysis Of A Software Package To Quantify In Vivo Polyethylene Wear After Total Hip Arthroplasty, Allison Kinney, Catherine Ambrose

Allison Kinney

Since the first total hip arthroplasty (THA) in 1938, THA evolved and developed into one of the major concentrations of orthopaedic research. The typical hip implant device used today incorporates a femoral and an acetabular component that serve to replicate the anatomical and mechanical functions of the natural hip joint. However, several problems exist that can effect the function of the implant device. Wear in the polyethylene liner of the acetabular component of the total hip replacement device is known as one of the major factors that affects the longevity of total hip replacement devices. Both manual and computer-aided techniques …

Inkjet Printing For High Throughput Cell Patterning, Elisabeth Roth, Tao Xu, Mainak Das, Cassie Gregory, Jay Hickman, Thomas Boland Dec 2003

Inkjet Printing For High Throughput Cell Patterning, Elisabeth Roth, Tao Xu, Mainak Das, Cassie Gregory, Jay Hickman, Thomas Boland

Thomas Boland

The adaptation of inkjet printing technology to the complex fields of tissue engineering and biomaterial development presents the potential to increase progress in these emerging technologies through the implementation of this high-throughput capability via automated processes to enable precise control and repeatability. In this paper, a method of applying high-throughput inkjet printing to control cellular attachment and proliferation by precise, automated deposition of collagen is presented. The results indicate that commercial inkjet printing technology can be used to create viable cellular patterns with a resolution of 350 microm through the deposition of biologically active proteins. This method demonstrates a combination …

Construction Of High- Density Bacterial Colony Arrays And Patterns By The Ink Jet Method, Tao Xu, Sevastioni Petridou, Eric Lee, Elisabeth Roth, Narendra Vyavahare, Jay Hickman, Thomas Boland Dec 2003

Construction Of High- Density Bacterial Colony Arrays And Patterns By The Ink Jet Method, Tao Xu, Sevastioni Petridou, Eric Lee, Elisabeth Roth, Narendra Vyavahare, Jay Hickman, Thomas Boland

Thomas Boland

We have developed a method for fabricating bacterial colony arrays and complex patterns using commercially available ink-jet printers. Bacterial colony arrays with a density of 100 colonies/cm(2) were obtained by directly ejecting Escherichia coli (E. coli) onto agar-coated substrates at a rapid arraying speed of 880 spots per second. Adjusting the concentration of bacterial suspensions allowed single colonies of viable bacteria to be obtained. In addition, complex patterns of viable bacteria as well as bacteria density gradients were constructed using desktop printers controlled by a simple software program.


Tissue-Engineering Constructs, Using Photopolymerizable Hydrogels And Stereolithography.”, Busaina Dhariwala, Elaine Hunt, Thomas Boland Dec 2003

Tissue-Engineering Constructs, Using Photopolymerizable Hydrogels And Stereolithography.”, Busaina Dhariwala, Elaine Hunt, Thomas Boland

Thomas Boland

One of the most important aspects of tissue engineering is the design of the scaffold providing the mechanical strength and access to nutrients for the new tissue. For customized tissue engineering, it is essential to be able to fabricate three-dimensional scaffolds of various geometric shapes, in order to repair defects caused by accidents, surgery, or birth. Rapid prototyping or solid free-form fabrication (SFF) techniques hold great promise for designing three-dimensional customized scaffolds, yet traditional cell-seeding techniques may not provide enough cell mass for larger constructs. This article presents a novel attempt to fabricate three-dimensional scaffolds, using hydrogels combined with cell …
