This thesis develops a flexible customer behavior analysis system, including essential head pose estimation or F-formation modules. This system will be evaluated in an actual retail store. Further, after studying the system, realizing the mentioned problems of the head pose problem, we also propose a process to collect the head pose dataset and multi-task deep neural network model, fusing face detection and head pose estimation to yield face position and head pose at the same time.

The system of relations between the consumer and the seller has many factors that shape the dynamics of the market of goods and services based on the supply chain strategy. Supply chains satisfy customers by striving for delivering the right products to the right place at the right time, at the right quality and at the right quantity within an increasingly faster pace and lower cost. Theories of social entropy consider the system of social relations from the standpoint of the equilibrium of systems and their disproportion.

The article discloses methodological approaches to quantifying the level of penetration of block chain technologies into the regional socioeconomic environment in comparison to the supply chain strategies. Based on the methods of mathematical and statistical analysis, it allows you to formalize and convert a large array of data of a qualitative order into a single scale for measuring the process under study - the level of demand in the regional socio-economic environment for block chain technology.

Semantic extraction from images is a topical problem and is applied in many different semantic retrieval systems. In this paper, a method of image semantic retrieval is proposed based on a set of images similar to the input image. Since then, the semantics of the image are queried on the ontology by the visual word vector.

This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.

This research focuses on two key research questions: how to measure spatial accessibility to green space in urban areas at fine resolution; and what is the status of spatial inequity in accessibility to green space in the MMA. Guided by the two research questions and based on a systematic review of literature on accessibility in general accessibility to green space in particular, a methodology has been developed for producing results needed to answer the research questions.

Once entirely the domain of space-borne applications, the effects of high energy charged particles on electronics systems is now also a concern for terrestrial devices. Reconfigurable components such as FPGAs are particularly vulnerable to radiation single event effects (SEU) as they carry a large amount of memory within a relatively small amount of circuit area. This thesis presents a Silicon on Insulator (SOI) based configuration memory system in a radiation hard reconfiguration system.

This research presents a method for the identification of hazardous situations on the freeways as well as the hazard mitigation system based on the identification. The hazard identification is done using a crash risk probability model and based on the identification, mitigation strategy is employed to reduce the effect of the hazard. For this study, about 18 km long section of Eastern Freeway in Melbourne, Australia is selected as a test bed.

This research investigates other built-in sensors and develops methods for improving the accuracy of indoor positioning. Combination with the wireless network, it can be a viable alternative solution for the indoor positioning purposes of the smartphone users. The main advantage of this solution is that it can be deployed with a minimal cost, as no specialized hardware is necessary for setting up the system.

Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

In this thesis, the rolling contact wear of 52100 bearing steel and Over-aged Magnesia-Partially-Stabilised Zirconia (OA-Mg-PSZ) ceramic are examined using a newly developed rolling contact wear test rig. The new wear test rig simulates the system geometry of an un-lubricated hybrid (ceramic and steel) ball bearing. The new wear test rig is versatile in that it allows low cost samples to be utilised resulting in a larger number of samples that can be tested.

The problem investigated is the potential gap between the rhetoric of the 'promise of e-business' versus the dynamics of enactment and impacts of ICT in practice in the social enterprise sector. The main contribution of the research is to identify the real development impact of lCT use by social enterprises by assessing the role of ICTs in achieving their goals. Its major finding is that SEs' social and business missions are inextricably linked .and their use of ICTs and benefits from it can be used as a proxy to assess ICTD. Thus SEs provide a new paradigm in the study of ICTD.

This purpose of this work was to investigate the patient radiation doses and image quality of a Philips/Agfa computed radiographic (CR) system and a Philips indirect-capture digital radiographic (DR) system in a paediatric setting. A CDRAD digital radiographic contrast-detail phantom was used to assess radiographic image quality. Perspex slabs of three different thicknesses (6, 11 and 16 cm) were used to simulate paediatric patients of three arbitrary ages.

This thesis presents a study of impedance optimisation of active microstrip patch antennas to multiple frequency points. A single layered aperture coupled microstrip patch antenna has been optimised to match the source reflection coefficient of a transistor in designing an active antenna. The active aperture coupled microstrip patch antenna was optimised to satisfy Global Positioning System (GPS) frequency specifications.

The study determines the predominant hydrogeological controls on salinity distribution and salinization/freshening, proposing conceptual models to explain the different vertical distributions of groundwater salinity at the coastline. An improved understanding of the sources of salinity and the hydrogeological controls will subsequently provide support for the future management of groundwater in the Western Port Basin, and serve as a template for how to unravel complex salinity distributions in coastal aquifers, and their relationships to palaeo- and recent geomorphological histories.

In this study, MCS is applied to compute the reliability of the nodes and the network under uncertain demand and roughness, and to determine how reliability is distributed among the various nodes of WDN, as well as assessing the reliability of the network as a series or parallel system. The effect of the resilience index on the nodal and network reliability is also assessed.
