Cell-seeded type II collagen scaffolds for articular cartilage tissue engineering
(Massachusetts Institute of Technology, 2007)
Defects in articular cartilage exhibit little spontaneous healing response, in part due to the limited number of chondrocytes available to infiltrate the defect and the absence of a provisional fibrin scaffold to accommodate ...
High-rate deformation behavior and applications of fluid filled reticulated foams
(Massachusetts Institute of Technology, 2007)
The need for smarter and adaptive, energy absorption materials especially for human protection applications has fueled the interest in new and alternative energy absorbing composites. In this thesis a 'novel' energy absorbing ...
Fracture of aluminum naval structures
(Massachusetts Institute of Technology, 2007)
Structural catastrophic failure of naval vessels due to extreme loads such as underwater or air explosion, high velocity impact (torpedoes), or hydrodynamic loads (high speed vessels) is primarily caused by fracture. ...
Mechanotransduction by talin : a molecular dynamics study of force-induced recruitment of vinculin to a focal adhesion complex
(Massachusetts Institute of Technology, 2007)
It is now well established that cells can sense mechanical force, but the mechanisms by which force is transduced into a biochemical signal remain poorly understood. One example is the recruitment of vinculin to reinforce ...
Efficient numerical methods for solving the Boltzmann equation for small scale flows
(Massachusetts Institute of Technology, 2007)
The Navier-Stokes equations of continuum fluid mechanics fail to accurately describe dilute gas flows when the characteristic lengthscale of the system is on the order of (or smaller than) the molecular mean free path. At ...
Reduced basis method for quantum models of crystalline solids
(Massachusetts Institute of Technology, 2007)
Electronic structure problems in solids usually involve repetitive determination of quantities of interest, evaluation of which requires the solution of an underlying partial differential equation. We present in this thesis ...
Effects of internal waves on low frequency, long range, acoustic propagation in the deep ocean
(Massachusetts Institute of Technology, 2007)
This thesis covers a comprehensive analysis of long-range, deep-ocean, low-frequency, sound propagation experimental results obtained from the North Pacific Ocean. The statistics of acoustic fields after propagation through ...
Laboratory evaluation of laser-induced breakdown spectroscopy (LIBS) as a new in situ chemical sensing technique for the deep ocean
(Massachusetts Institute of Technology, 2007)
Present-day expeditionary oceanography is beginning to shift from a focus on short-term ship and submersible deployments to an ocean observatory mode where long-term temporally-focused studies are feasible. As a result, a ...
Structural vibration damping using lightweight, low-wave-speed media
(Massachusetts Institute of Technology, 2007)
Incorporation of a low-density, low-wave-speed medium (LWSM) into a structure yields significant damping if the speed of wave propagation in the medium is low enough for standing waves to arise in it. In this thesis, we ...
The design of a microfabricated air electrode for liquid electrolyte fuel cells
(Massachusetts Institute of Technology, 2007)
In this dissertation, the microfabricated electrode (MFE) concept was applied to the design of an air electrode for liquid electrolyte fuel cells. The catalyst layer of the electrode is envisioned to be fabricated by using ...
