Resource Allocation in 5G: NR Sidelink Mode 2 & Wi-Fi 6/7
… describing the NR SL PRR. The existing models ignore the relationships between SPS parameters and, therefore, do not provide sufficient insights into the PRR of SPS. This work proposes a novel SPS PRR model incorporating MAC collisions based on new features in NR SL. We extend our model …

L-band RFI measurement system simulation and investigation
… protocol divides measurements into two parts, Mode 1 and Mode 2. Mode 1 is defined for the observation of strong RFI and is relevant for SKA receiver linearity analysis. Mode 2 is defined for the observation of weak interferences, which potentially threatens to obscure weak signals of interest. …

The effect of stiffness and mass on the dynamic response of wood floors
… The boundary conditions investigated affect the mode 2 resonant frequency, but have no significant effect on the damping ratio and RMS acceleration. In addition, the load sharing capacity was evaluated in terms of the percentage of load carried by each joist within a floor.

Application of model predictive control on wind farm incorporated with dual battery energy storage system
… in this thesis focuses on the application of Model Predictive Control (MPC) to Dual Battery Energy Storage System (dual BESS) so that the reference power from the actual wind farm power can be tracked with satisfactory performance. The control strategy considers certain practical constraints …

Neural network estimation of disturbance growth and flow field structure of spatially excited jets
… flow structures of a jet undergoing spatial mode excitation. The evolution of disturbances introduced by a spatially excited jet spans a linear and nonlinear regime in the downstream flow field. For the linear portion, the neural network was trained to identify critical flow field parameters …

Tonalness and consonance of technical sounds
… of the machine is described. A simple analytic model (using two quadrupoles) serves as a first approximation. Afterwards the results of the numerical simulation (FEM-BEM) are presented and compared with the measured data. The constructed eddy-current test bench as well as the multi-channel …

Modal pushover analysis for high-rise buildings
… of structures. Since only the fundamental mode is considered and the inelastic theorem is imperfect for the conventional pushover analysis, a modified Modal Pushover Analysis (MPA) is proposed by researchers. In this thesis, the theories of dynamics for single-degree-of-freedom (SDOF) and …

Analytic and numerical study of underwater implosion
… for plastic energy dissipation of a symmetric mode 2 collapse; results agree with numerical simulations within 10%. A novel pseudo-coupled fluid-structure interaction method was developed to predict the energy transmitted in the implosion pulse; results agree with fully-coupled numerical …

Plasma N-terminal Proatrial Natriuretic Peptide Concentration in Cats with Hypertrophic Cardiomyopathy
… relationship between plasma [Nt-proANP] and M-mode, 2-dimensional and Doppler echocardiographic variables was evaluated. Cats that were hyperthyroid or had evidence of renal disease were excluded from the study. Results: The mean plasma [Nt-proANP] was higher in cats with HCM (3.81 +/- 1.23 …

Health systems thinking : the need for a more critical approach
… It does not intend to develop a blue print model but rather a more critical approach to deal with some of the intractable problems encountered in current health sector reforms. The thesis is not expected to serve public health practitioners only but also systems thinking theorists, …
