Low power rf transceivers
… of modulation (On-Off Keying) and demodulation (non-coherent) are presented. Furthermore, it is shown how Super-Regenerative Receivers (SRR) can be used to achieve relatively large output voltages for small input powers. This is important because baseband Op-Amps connected at the RF receiver …

Reduced corticosteroid sensitivity in smokers with asthma: potential mechanisms and treatment
… a number of other sputum cytokines compared to non smokers with asthma. This altered phenotype suggests cigarette smoking in asthma may be associated with a deviation to Th1 mediated inflammation and could provide an explanation for the reduced corticosteroid response of smokers with asthma. The …

Performance Evaluation of RC Flexural Elements Strengthened by Advanced Composites
… limit state and (d) to carry out analytical modelling using a commercial FE package. <br/><br/>The experimental investigation comprised of testing 55 simply supported RC beams of either 1.5m or 2.6m length. In addition to the parametric studies included in points (a)-(d) above (to assess the …

THE EXPLORATION OF THE VALIDITY OF QUANTITATIVE 2-DEOXY-2-[FLUORINE-18] FLUORO-D-GLUCOSE (18F-FDG) POSITRON EMISSION TOMOGRAPHY/COMPUTED TOMOGRAPHY (PET/CT) TO ASSESS LUNG INFLAMMATION
… spatial and temporal distribution of the tracer; linear and non-linear modelling techniques allow estimation of the metabolic rate of 18F-FDG in the lung. Previous studies have used a linear method called Patlak graphical analysis, whilst non-linear compartmental models have been used more …

Ductility and deformability of FRP strengthened reinforced concrete structures
… making any strengthening redundant.<br/><br/>A non-linear numerical model has been created and verified using the data acquired from the experimental programme. This will enable the prediction of element deflection up to ultimate load and, hence, allow the ductility to be quantified during the …

A Non-linear Visco-elastic Model for Dynamic Finite Element Simulation of Bovine Cortical Bone
Modelling and simulation of the human body during an impact situation such as a car accident, can lead to better designed safety features on vehicles. In order to achieve this, investigation into the material properties and the creation of a numerical model of cortical bone is needed. One approach …
