Structural models

Recently, machine learning (ML) algorithms have proven to be highly effective tools for predicting structural damage. However, the data used in structural health monitoring often consists primarily of normal operational conditions or slight deviations from the original state, with a scarcity of data representing potentially dangerous conditions.

This paper presents a system that combines torque control algorithms based on a back-propagation neural network (BP-ANN) and an Adaptive Neuro-Fuzzy Inference System (ANFIS). The BP-ANN uses a multi-layer structure where the input layer processes factors such as load torque, rotational speed, and stator current, hidden layers model complex nonlinear interactions, and the output layer predicts optimal torque for AFPMSM operation.

The paper proposes an empirical VAR for the UK open economy in order to measure the effects of monetary policy shocks from 1981 to 2003. The identification of the VAR structure is based on short-run restrictions that are consistent with the general implications of a New Keynesian model. The identification scheme used in the paper is successful in identifying monetary policy shocks and solving the puzzles and anomalies regarding the effects of monetary policy shocks.

The aim of this Master of Engineering (MEng) - Aerospace thesis is to study the structural response and failure of aerospace grade composites during exposure to fire. Key aspects of the research are to analyse the thermal and mechanical responses of laminates and sandwich composites in high temperature and fire environments, which result in softening and structural failure. The research is concentrated on carbon/epoxy laminates and sandwich composites, which are the most common composite materials used in aerospace structures.

Tensegrity is a structural system constructed of tensile cables and compressive bars. This thesis proposes several general methods for creating tensegrity structures. The author has developed new methods for creating specific tensegrity cells and the corresponding computer code. Furthermore, the author has constructed various physical models to validate the methods. A proposal for an observation tower on top of the Eureka building in Melbourne has also been devised by the author.

This thesis examines the implications of public sector HRM architecture and its impact on HR professionals, senior managers and employees who are integral to service delivery in the public sector. To achieve its objective, conclusions are based on findings from practitioners and employing organisations, in a context of the prominent literature in this field. A mixed methods approach was adopted with 54 semi-structured interviews conducted in case study organisations representing an in-house, shared service and outsourced model of HRM.
