PhD title: Studying groundwater properties and behaviour using geospatial techniques

Supervisors:  Prof Stuart Marsh and Prof Rachel Gomes

Research Summary
Monitoring of groundwater quantity and quality is important for survival of mankind. Major movements in groundwater can cause surface subsidence and uplift. We study these surface motion using radar interferometry, and groundwater motion using GRACE gravimetry, and validate our results with ground observation data. We also study groundwater quality using observed data for last 20 years and aim to develop a model to link groundwater quantity and quality variations.

PhD title: Comparsion of some transformation procedures for the Nigerian Geodetic Network

Supervisors: Prof Terry Moore and Dr Chris Hill

Research Summary 

Our position on the surface of the earth is defined by horizontal coordinates, latitude and longitude, which is in the past, referenced to local datum while the vertical coordinates, orthometric height, is referenced to the vertical datum.  The unification of the two datum came with the advent of space technology which is based on the global datum.    Coordinates can thus be transformed from one datum to another through datum transformation.     This research is investigating different transformation models to derive set of transformation parameters for the Nigerian Geodetic Network to transform coordinates from global datum to local datum and vice versa.

PhD title: High Accuracy Multi-Constellation Multi-Frequency GNSS

Supervisors: Prof Terry Moore and Dr Chris Hill

Research Summary 

With the evolving GNSS landscape, the IGS has started the Multi-GNSS Experiment to produce products for new constellations. However, at the moment these products can only be used in post-processing. In my research, a simulator of Multi – GNSS observations and Real – Time products has been developed to analyse the performance of GPS only, Galileo only and GPS plus Galileo Precise Point Positioning. The impact of different signals combined in the Ionosphere – Free combination and the potential of the Galileo E5 signal are analysed. Finally alternative methods of ionosphere delay mitigation are considered in order to ensure the best possible positioning performance.

PhD title: Required Localisation Performance of Connected and Autonomous Vehicles

Supervisors: Dr Xiaolin Meng and Dr Simon Roberts

Research Summary

This project aims to establish requirement metrics of CAV in localisation and develop integrated localisation solutions for CAV. The required localisation performance of CAV will consist of three main parts, which are satellite positioning, sensing and communication. The relevant parameters, such as accuracy, availability, cost etc., will be defined and set up. The integrated localisation solutions will then be realised by the advanced algorithms which aims to provide required positioning performance in real driving environment. All the requirement metrics will then be assessed via a prototype CAV platform to verify and refine the CAV parameters.

PhD title: Trust and Calibration of Trust in Connected and Automated Vehicles

Supervisors:  Dr Xiaolin Meng, Dr Gary Burnett and Dr Catherine Harvey

Research Summary 

The focus of this Ph.D. is given by the new area that has emerged: the rise of the connected and automated vehicle. Although the concept is an old one that can be found in utopic/dystopic literature, early attempts to create driverless vehicles have existed before but only with the recent project sponsored by DARPA, the driverless car has stepped closer towards becoming a reality. Appropriate levels of trust are an integral part in the successful deployment of such vehicles, especially since the trust of a user in the automated system is crucial for its use, disuse or abuse. Although some of the technologies that are incorporated into driverless cars have already existed in other fields such as aviation (autopilot), the driver-vehicle-environment system has specific characteristics and consequently, knowledge from other areas does not necessarily transfer.

PhD title: Novel integrated sensor technologies for rich geospatial data capture techniques from mobile platforms

Supervisors:   Dr Martin Smith and  Prof Stuart Marsh

Research Summary
Never before has the world been so concerned about the environment and yet never before has the world had so many tools to measure and monitor it at such a high resolution. This has recently been accelerated through novel sensor integration, information extraction techniques and major improvements to airborne platforms, particularly Unmanned Aerial Vehicles with a capacity to carry the novel sensors. However, the scientific potential of UAV’s is far from mature.
This research will assess the use of mobile platforms (vehicle, personal and airborne), with respect to environmental monitoring and the sustainability of cities. The increasing availability of imaging sensors, multi-spectral sensors, and small LiDAR systems will be investigated. This PhD will focus on new sensor technologies, big data capture techniques and information extraction to monitor and model the natural and built environment alike.

In recent decades, the oil industry has contributed significantly to land cover change within the Niger Delta region of Nigeria. However, the true extent and severity of the land cover change due to oil production and exploration activities remains unclear. Therefore, the aims of this project are:

  • To detect and model the magnitude, nature, direction and the likelihood of land cover changes in the Niger Delta.
  • To determine and model the relationship between oil activities and the land cover changes.
  • To model the proportional change in land cover due to variation in the amount of oil extraction

PhD title: Indoor Positioning as a Contribution to Building Occupant Modelling

Supervisors: Prof Terry Moore, Dr Peer-Olaf Siebers and Dr James Pinchin

Research Summary 

Assessing building performance related to energy usage requires knowledge of occupancy patterns together with a lot of other behavioral factors. Due to the limitations of passive sensors in detecting an individual's occupancy throughout the building, indoor positioning (IP) techniques can provide a viable alternative but requires a robust positioning solution to be deployed. This creates an opportunity for research in novel application areas of indoor positioning to solve real-world problems of detecting building occupancy. 

The interdisciplinary nature of this PhD focuses on how we can bring together existing IP elements and demonstrate its contribution to the development of Building Occupant Models to understand building energy usage. It requires the development of an IP system which can be used to detect our intricate pattern of occupancy not just limited to private office space but rather spanning the entire building including corridors, hallways, stairs, and kitchens.

PhD title: The uses of fine remote sensing techniques in modelling Sand Movement in Sudan

Supervisors: Prof Stuart MarshDr Martin SmithDr Panagiotis Psimoulis

Research Summary

Sand movement is the main environmental issue in Sudan, leading to hazards such as the burial of cultural heritage sites. In this research, we will use remote sensing techniques (i.e. satellite images and aerial images) and land surveying techniques (i.e. GNSS, total station and levelling instruments) to understand and monitor sand movement changes, with respect to the influencing factors and its impact on urban areas, crop fields, forests, water bodies and archaeological sites. In addition, this research will focus on studying the effect of the various heights of sand dunes on the horizontal sand movement rate. What is expected from this research is to develop a modelling technique that uses the height of sand dunes to model sand movement.

PhD title: Rural Communications for Connected and Autonomous Vehicles

Supervisors:  Prof Xiaolin Meng, Prof Stuart Marsh and Dr Julia Jing

Research Summary
Communications are an integral part of future transport systems, particularly for Connected and Autonomous Vehicles (CAV). In rural areas, where communication is lacking, roads are fast, narrow, poorly maintained and dangerous. If the vehicles using these roads can communicate with each other and their surrounding infrastructure, awareness of these dangers can be improved. This PhD project investigates the high speed and reliable connectivity solutions required to improve vehicle safety and efficiency in rural areas whilst avoiding expensive and intrusive hard infrastructure that can degrade the natural characteristics of rural areas. Specifically, this PhD explores the use of satellite communication solutions and 5G technologies to develop effective communication methods for CAVs. The aim is to develop solutions that can then be applied to alternative use cases including mobile communications, rail and marine transport systems, and less developed transport systems overseas.

PhD title: Assessment of the accuracy of low cost GPS receivers integrated with acclerometers for the monitoring of dynamic motion of structures

Supervisors: Dr Xiaolin Meng and Dr Panagiotis Psimoulis

Research Summary 

Although GNSS technologies are used broadly in structural health monitoring of stiff civil engineering structures, the relatively high cost of GNSS receivers adopted are restraining their applications. Therefore, the aim of my project is to investigate the accuracy of low-cost GNSS receivers in monitoring low and high frequency motion and evaluate the potentials of low-cost GNSS receivers in monitoring civil engineering structures. The investigation will first focus on defining noise characteristics of the low-cost GNSS receivers experimentally, then the low-cost GNSS receivers will be assessed in monitoring the motion based on the motion frequency in the lab followed by data analysis and real infrastructure monitoring.
