A comparison of strain and fluid shear stress in stimulating bone cell responses - a computational and experimental study
(2005)Bone undergoes continuous remodeling in response to mechanical loading. However, the underlying mechanisms by which bone cells respond to their changing mechanical environment, that is, strain in the load-bearing matrix ... -
Chondrogenesis and integration of mesenchymal stem cells within an in vitro cartilage defect repair model
(2009)Integration of repair tissue is a key indicator of the long-term success of cell-based therapies for cartilage repair. The objective of this study was to compare the in vitro chondrogenic differentiation and integration ... -
A High-Precision Apparatus for the Characterization of Thermal Interface Materials
(American Institute of Physics, 2009)An apparatus has been designed and constructed to characterize thermal interface materials with unprecedented precision and sensitivity. The design of the apparatus is based upon a popular implementation of ASTM D5470 ... -
Evaluation of high frequency vibrations using electronic speckle pattern interferometry
(2002)The available techniques for the study of high frequency vibration using electronic speckle pattern interferometry (ESPI) are briefly surveyed. We concentrate on two methods in particular. The first is a straightforward ... -
Natural convection from isothermal horizontal cylinders
(ASME, 2009)The research described here is concerned with natural convection from isothermal cylinders, with a particular focus on the interaction between a pair of vertically aligned cylinders. Prime attention was focused on how ... -
Heat transfer characteristics of swirling impinging jets
(ASME, 2009)Impinging jets are used in a wide number of industrial cooling applications due to their high heat and mass transfer abilities. The current research is concerned with the effect of swirl on the heat transfer characteristics ... -
Time averaged and fluctuating heat transfer measurements in an atomising mist jet nozzle
(ASME, 2009)Much is already known about the heat transfer characteristics of impinging air jets, and they are widely used in many engineering applications. There currently exist many correlations describing such characteristics. ... -
Heat transfer and air temperature measurements of an impinging synthetic air jet
(2009)Synthetic jets are a relatively new technology that can achieve high rates of heat transfer. They have been shown to out-perform comparable steady impinging jets without the need for an external air supply system. The ... -
Nonlinear vibro-acoustic behaviour in a circular membrane oscillator
(2009)Oscillating systems that produce noise at a frequency of excitation may have as an abatement solution the increase of the frequency of excitation to above the audible frequency limit, viz. 20kHz. This approach may not ... -
To Design a Designer To Design Designs
(Trinity Centre for Bioengineering, Trinity College Dublin, 2008)This paper reports on the implementation of a new project based design course at first year level of an engineering degree programme. The project, carried out in groups of six, uses the design and construction of ... -
Functional Properties of Cartilaginous Tissues Engineered From Infrapatellar Fat Pad Derived Mesenchymal Stem Cells.
(2010)Articular cartilage has a poor intrinsic capacity for self-repair. The advent of autologous chondrocyte implantation has provided a feasible method to treat cartilage defects. However, the associated drawbacks with the ... -
Stresses in peripheral arteries following stent placement: a finite element analysis
(2009)The success of stents to restore blood flow in atherosclerotic peripheral arteries is low relative to coronary arteries. It has been shown that joint flexion induces a mechanical environment that makes stent placement in ... -
Determination of two-dimensional space-time correlations in jet flows using simultaneous PIV and LDV measurements
(2010)The two-dimensional space-time turbulence statistics of free shear jet flows in the form of the two-point velocity correlation tensor are important for aeroacoustic noise source modelling based on the acoustic analogy ... -
Noise Source Location in Turbomachinery Using Coherence Based Modal Decomposition (AIAA 2009-3367)
(2009)Coherence based source analysis techniques can be used to identify the contribution of turbomachinery core noise sources to pressure measurements in the far-field. The usual approach is to locate a measurement sensor ... -
Modelling multi-modal sound transmission from point sources in ducts with flow using a wave-based method
(2009)An understanding of the multi-modal propagation of acoustic waves in ducts is of practical interest for use in the control of noise in, for example, aero-engines, automotive exhaust and ventilation systems. In this paper, ... -
Jet heat transfer in the vicinity of a rotating grinding wheel
(Professional Engineering Publishing, 2006)Impinging jets are known as a method of achieving high convective heat transfer coefficients. One potential application of impinging jet heat transfer is the air jet cooling of a grinding process. A grinding process ... -
Mechanics applied to skeletal ontogeny and phylogeny
(Springer, 2002)The musculo-skeletal system serves the mechanical function of creating motion and transmitting loads. It is made up mainly of four components: bone, cartilage, muscle and fibrous connective tissue. These have evolved over ... -
Experimental investigation of small diameter two-phase closed thermosyphons charged with water, FC-84, FC-77 & FC-3283
(Elsevier, 2009)An experimental investigation of the performance of thermosyphons charged with water as well as the dielectric heat transfer liquids FC-84, FC-77 and FC-3283 has been carried out. The copper thermosyphon was 200 mm long ... -
Nozzle Geometry Effects in Liquid Jet Array Impingement
(Elsevier, 2009)The use of impinging liquid jets in electronics thermal management is attracting some consideration due to their very high heat transfer coefficients, hot spot targeting capabilities and moderate hydraulic power requirements. ...
