The Program Evaluation and Review Technique (PERT) is a popular scheduling technique that takes advantage of the Beta distribution to present uncertainty in activity durations. This study presents an advanced PERT method with an improved Bayesian updating and improved assumed prior distributions, which better represent real-world projects.

In the design and calculation of stormwater drainage systems, the design rainfall intensity plays a crucial role and is widely used in runoff calculations. Due to the influence of local climatic factors, the selection of probability distributions for rainfall frequency analysis and the methods used to determine parameters for empirical equations result in a variety of equations compared to traditional Rainfall Intensity-Duration-Frequency curves.

This study also contributes to reducing environmental pollution caused by plastic and glass waste as well as current construction brick production methods. The results show that the bulk density, compressive strength, and bending strength of brick samples made from PET plastic and glass waste are higher than those of burnt clay brick samples, while water absorption is much smaller than that of burnt clay brick samples.

The chosen algorithm for this project is the MLP (Multi-layer Perceptron) classifier, which has seen significant development in recent years and has widespread applications in various Al domains. This is why it has been selected as the foundation for the system in this project. The research topic aims to utilize this algorithm to construct a system that rapidly predicts whether a mushroom is edible or poisonous, facilitating practical applications.

The servlet is constructed, then initialized with the init method. Any calls from clients to the service method are handled. The servlet is taken out of service, then destroyed with the destroy method, then garbage collected and finalized.GenericServlet implements the Servlet and ServletConfig interfaces. It provides simple versions of the lifecycle methods init and destroy and of the methods in the ServletConfig interface.

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 research project will investigate how combining systems of tessellation1 , modularity2 and seriality3 can be utilised with a specific method of paper staining to explore visual pathways within an artwork. A serial system4 of modular tessellation will be implemented, whereby different “sets” of oil-and-pigment soaked paper modules will be constructed and formed into various configurations.
