    • Contributions to Engineering Big Data Transformation, Visualisation and Analytics. Adapted Knowledge Discovery Techniques for Multiple Inconsistent Heterogeneous Data in the Domain of Engine Testing

      Not named; Jenkins, Natasha N. (University of BradfordDepartment of Computer Science. Faculty of Engineering and Informatics, 2022)
      In the automotive sector, engine testing generates vast data volumes that are mainly beneficial to requesting engineers. However, these tests are often not revisited for further analysis due to inconsistent data quality and a lack of structured assessment methods. Moreover, the absence of a tailored knowledge discovery process hinders effective preprocessing, transformation, analytics, and visualization of data, restricting the potential for historical data insights. Another challenge arises from the heterogeneous nature of test structures, resulting in varying measurements, data types, and contextual requirements across different engine test datasets. This thesis aims to overcome these obstacles by introducing a specialized knowledge discovery approach for the distinctive Multiple Inconsistent Heterogeneous Data (MIHData) format characteristic of engine testing. The proposed methods include adapting data quality assessment and reporting, classifying engine types through compositional features, employing modified dendrogram similarity measures for classification, performing customized feature extraction, transformation, and structuring, generating and manipulating synthetic images to enhance data visualization, and applying adapted list-based indexing for multivariate engine test summary data searches. The thesis demonstrates how these techniques enable exploratory analysis, visualization, and classification, presenting a practical framework to extract meaningful insights from historical data within the engineering domain. The ultimate objective is to facilitate the reuse of past data resources, contributing to informed decision-making processes and enhancing comprehension within the automotive industry. Through its focus on data quality, heterogeneity, and knowledge discovery, this research establishes a foundation for optimized utilization of historical Engine Test Data (ETD) for improved insights.
    • Assessment of Thermally Enhanced Geo-Energy Piles and Walls

      Mohamed, Mostafa H.A.; Elkezza, Omar A.A. (University of BradfordSchool of Engineering. Faculty of Engineering and Informatics, 2023)
      Geo-energy piles and walls have long been recognized as a promising way to reduce carbon dioxide emissions while providing renewable energy. However, enhancing the thermal performance of these structures has remained a signif-icant challenge. This thesis evaluated five different approaches to improving the thermal performance of geo-energy piles and walls, through a series of experiments using a fully instrumented testing rig. The first approach involved adding graphTHERM powder to concrete to double its thermal conductivity, boosting heat transfer efficiency by an impressive 50% to 66%. The second approach tested slag-based geopolymer concrete as a sustainable construc-tion material for geo-energy piles and walls, reducing CO2 emissions by 44.5% while improving thermal performance by 14% to 21%. The third approach in-volved testing thermally enhanced soils at the geo-energy structures/soil inter-face, resulting in an 81% improvement in heat transfer efficiency. The fourth approach utilized innovative phase change material (PCM) heat exchangers that increased heat transfer efficiency by 75% and 43% in heating and cooling operations, respectively. Finally, incorporated PCM-impregnated light weight aggregates at the interface of the structure soil, significantly increasing tem-perature difference and reducing thermal deformation of geo-energy struc-tures.Overall, these innovative approaches made a significant contribution to enhancing the thermal performance of geo-energy piles and walls. However, approaches four and five, which involve utilizing PCM heat exchangers and PCM-impregnated LWA's, respectively, showed extra benefits in dropping the thermal effect on soils and reducing the thermal damage on those structures. These techniques offer great promise for improving the thermal performance of geo-energy structures.

    • Design and Implementation of Reconfigurable and MIMO Antennas for Future Heterogeneous Wireless Systems

      Abd-Alhameed, Raed; Elfergani, Issa T.; Mshwat, Widad F.A.G.A. (University of BradfordDepartment of Biomedical and Electronics Engineering. Faculty of Engineering and Informatics, 2024-04-10)
    • Planning and Operation of Hybrid AC-DC Microgird with High Penetration of Renewable Energy Sources

      Mokryani, Geev; Baseer, Muhammad (University of BradfordSchool of Biomedical and Electronics Engineering. Faculty of Engineering and Informatics, 2022)
      A hybrid ac/dc microgrid is a more complex but practical network that combines the advantages of an AC and a DC system. The main advantage of this network is that it connects both alternating current and direct current networks via an interlinking converter (IC) to form a unified distribution grid. The hybrid microgrid (HMG) will enable the direct integration of both alternating current (AC) and direct current (DC) distributed generators (DGs), energy storage systems (ESS), and alternating current and direct current (DC) loads into the grid. The alternating current and direct current sources, loads, and ESS are separated and connected to their respective subgrids primarily to reduce power conversion and thus increase overall system efficiency. As a result, the HMG architecture improves power quality and system reliability. Planning a hybrid microgrid entails estimating the capacities of DGs while taking technical, economic, and environmental factors into account. The hybrid ac-dc microgrid is regarded as the distribution network of the future, as it will benefit from both ac and dc microgrids. This thesis presents a general architecture of a hybrid ac-dc microgrid, which includes both planning and design. The goal of the Hybrid ac-dc microgrid planning problem is to maximise social welfare while minimising total planning costs such as investment, maintenance, and operation costs. This configuration will assist Hybrid microgrid planners in estimating planning costs while allowing them to consider any type of load ac/dc and DER type. Finally, this thesis identifies the research questions and proposes a future research plan.

    • Designing and Building a Novel Magnetic Heating System to Investigate the Dependence of the Magnetic System and the Optical Emission from Nanoparticles

      Drake, Philip; Swift, Thomas; Abd-Alhameed, Raed; Algaddafi, Ali E. (University of BradfordSchool of Chemistry and Biosciences. Faculty of Life Sciences, 2022)
      A Magnetic Heating Coil (MHC) has been designed, which has the potential to interact with magnetic Nanoparticles (NPs) to produce local temperature changes. The aim is to design a device capable of studying medically targeted magnetic-fluorescent core-shell NPs (with potential applications in cancer therapy via hyperthermia). Very little is known about how the magnetic-fluorescent NPs respond to magnetic fields and the effect this would have on their optical properties, therefore, considerable work is still required in order to understand the detailed interactions. Several modelling and simulations of the MHC were conducted besides developing the MHC that was designed and built for small samples of NPs (1-10ml volumes). Two different heating coil geometries were examined (coil A and coil B), where the former operates at 83 kHz and the latter operates at 125 kHz. Several tests for fluorescent emission, lifetime and anisotropy with several different NPs samples were conducted. We found that as the temperature increased from 5 °C to 45 °C, the fluorescence lifetime dropped from 3.8 ns to 3.6 ns. Also, the correlation time of the fluorescence in dilute solutions with varying temperatures from 20 °C to 40 °C was investigated, and it was found that decreased from 0.9 ns to 0.6 ns showing that the rotational diffusion of the dye increased and the molecules become more mobile. The MNPs were found to quench the fluorescent emission at high concentrations. Also, the MNPs induce only a small change in a lifetime from 3.9 ns to 3.4 ns.
    • A Strategic Public Diplomacy Framework for Enhancing Implementation of Public Diplomacy Practice in the Diplomatic Field of Qatar

      Shahi, Afshin; Alhamar, Nasser A.J. (University of BradfordFaculty of Management, Law and Social Sciences, 2023)
      The role of Public Diplomacy (PD) in conducting foreign relations has emerged as a critical component for modern statecraft, foreign policy and arguably for the state’s global existence. With the world now more interconnected than ever before, public diplomacy has taken on new meaning and new importance. However, despite these marked shifts, public diplomacy remains under-researched and under-utilised both as a concept and as a vital activity. The complexities that underscore the development and evolution of public diplomacy within a dynamic international milieu therefore warrant renewed attention. The benefits and opportunities that accompany public diplomacy are equally complicated by a number of challenges to its practice. This research identifies and advances a critical understanding of public diplomacy through a theoretically rigorous perspective that accounts for the fluid environment in which it operates, the evolving nature of stakeholders and audiences involved in shaping it, the sweeping impact of global information and communications development, the persistence of cultural divides and conflicts of interests and how they contribute to the lack of strategic frameworks in place to advance public diplomacy practice. This thesis investigates Qatar as a case study due to its international stature and influence despite it being a small geographical state. Renowned for its international role as a leading actor in conflict reconciliation and commended for its contributions to international humanitarianism, the ambitious, forward-looking and steadfast foreign policy of Qatar has faced increased pressure in recent years. Qatar has encountered significant challenges in the form of the Nepali workers’ crisis that ensued following its selection as host for FIFA World Cup 2022 and with the diplomatic siege against it by a number of Gulf Cooperation Council (GCC) states. This study critically analyses Qatar’s public diplomacy practice considering these pressing developments and advances an original strategic public diplomacy framework that can assist Qatar in managing and mitigating the effect of these crises on its global image and reputation. This research contributes to enhancing public diplomacy practice within the diplomatic context of statecraft and foreign policy by developing a nuanced and original framework that can be utilised by Qatar and other states to manage and mitigate modern public diplomacy challenges. The thesis utilises a mixed-methods research approach that includes literature reviews, media analyses, interviews and questionnaires. The study contributes to knowledge and practice by advancing research in an understudied field and by developing and implementing an original strategic PD empowerment framework.
    • The development and validation of a brand-building framework for platform-centric startups

      Ismagilova, Elvira; Weerakkody, Vishanth J.P.; Roshanzamir, Amir H. (University of BradfordSchool of Management. Faculty of Management, Law, and Social Sciences, 2022)
      Platform-centric startups that generate value by facilitating interactions between two or more interdependent groups digitally transform and disrupt the business environment, leading to significant changes in how people purchase, sell, communicate, and even live. Some of these, such as Uber and Airbnb, have become among the most beloved and successful brands, though they had serious challenges in building up their brands at the early stages due to lack of resources. The purpose of this dissertation is to develop a framework of branding in platform-centric startups by identifying the pillars of brand‐building and linking the relevant factors. This study employs qualitative method to propose a four-level framework including passion, innovation, co-creation, and moralization for brand-building in startups. The novelty of this framework reveals that the locus of brand-building is gradually expanding from the founders to the company, then to the customers, and finally to a larger societal constituency. The framework can assist founders and stakeholders in monitoring the growth of a new venture in the real business world while guiding branding scholars to investigate the discipline of startup branding.
    • Competence and Professional Advancement in Computed Tomography (ComPACT)

      Hardy, Maryann L.; Scally, Andy J.; Harris, Martine A. (University of BradfordFaculty of Health Studies, 2022)
      Background: Evolving technology, practice boundaries, and models of service provision have changed what the diagnostic radiography workforce in Computed Tomography (CT) need to know and be able to do at different career stages. It is unknown whether existing UK educational and practice frameworks support CT roles, or how organisational role descriptors constitute CT competence. Aims: The study explores multiple stakeholder perspectives of competent practice in diagnostic radiography and CT using this information to generate and gain consensus on novel modality-specific skills for the four-tier radiography structure. Methods: Study 1: Document analysis of published UK educational and practice frameworks using content and framework analysis. Study 2: Document analysis of UK CT role descriptors using a context analytical approach. Study 3: Modified e-Delphi study to gain consensus on novel technical and clinical CT practice competencies. Results: Existing radiography competencies were classified into 3 themes: delivering person-centred care; applying technical principles, quality and efficiency; and ensuring best practice. Generic competencies endorsed by professional and regulatory bodies were not consistently replicated within organisational role descriptors. CT practice expectations are ambiguous and modified from radiographic competencies. Modified e-Delphi panellists provided judgement on 215 practice competencies and advanced capabilities which have been refined and organised into a coherent framework. Conclusions: The ComPACT framework formalises the tacit technical knowledge, clinical competencies and professional capabilities that specifically address the practice area of CT. Further work is required to validate the framework and define educational standards, but there is potential to influence future graduates, workforce development and national standards.

    • Food Waste Reduction through Food Sharing Initiatives: The lived Experiences of Restaurants and Food Bank Employees in Riyadh

      Sharif, Amir M.; Sivarajah, Uthayasankar; Eldabi, Tillal; Abdur-Rahim, Abdulwasih I. (University of BradfordSchool of Management. Faculty of Management, Law, and Social Sciences, 2023)
      Today’s world is characterised by considerable inconsistency. In some parts of the world people are living in starvation and malnutrition, while in some other parts of the same world, about 1.3 billion tons of food is wasted every year. We do not know enough about what contributes to food waste. However, there seems to be an emergent pattern of behaviour around sharing food. This hermeneutic phenomenological research will explore how food sharing might reduce food waste in a cultural and community-based society like Saudi Arabia through the lived experiences of restaurants and food bank employees. Research data were collected through a face-to-face semi-structured interview method from 15 participants from selected restaurants and food bank in Riyadh. Using the theory of planned behaviour (TPB) as the theoretical lens, a conceptual framework was proposed to elicit underlying behavioural and cultural factors impeding food waste reduction and the inefficiency of food sharing. Using Paul Colaizzi’s approach, the collected interview data were reviewed, analysed, and seventeen themes were elicited for further discussion. The findings suggest that culture through an affluent way of life and the show-off lifestyle of hosts continue to contribute to more food wastage. The strictly business nature of restaurants operation leads to edible food fit for human consumption ending up in the garbage. The revised conceptual framework provides insight into the factors hindering food waste reduction and food sharing. With supporting regulations and policies, food leftovers can either be distributed to people in need or put to an alternative use.
    • Application of Hansen Solubility Parameters and Thermomechanical Techniques to the Prediction of Miscibility of Amorphous Solid Dispersion. Investigating the role of cohesive energy and free volume to predict phase separation kinetics in hot-melt extruded amorphous solid dispersion using dynamic mechanical analyser, shear rheometer and solubility parameters data

      Isreb, Mohammad; Gough, Timothy D.; Timmins, Peter; Mousa, Mohamad A.M.R. (University of BradfordSchool of Pharmacy. Faculty of Life Sciences, 2022)
      Hot-melt extruded solid dispersion technique is increasingly employed to improve the solubility of poorly water-soluble drugs. The technique relies on the enhanced solubility of the amorphous form of the drug compared to its crystalline counterpart. These systems however are thermodynamically unstable. This means that the drug crystallises with time. Therefore, efforts to measure the stability of these systems over the life span of the product are crucial. This study focused on investigating the use of Hansen Solubility Parameters to quantify polymer-drug interaction and to predict the stability of solid dispersions. This was achieved through a systematic review of hot-melt extruded solid dispersion literature. The study also investigated the use of a combined mechanical and rheological model to characterise the physicochemical and release behaviour of three solid dispersion immediately after preparation and after storage for one month at 40oC or three months at room temperature. Results revealed that the total solubility parameter |ΔбT| was able to predict the stability of the systems for more than 4 months using a cut-off point of 3 MPa-1 with a negative predictive value of 0.9. This was followed by ΔбD with a cut-off point of 1.5 MPa- 1. Moreover, Dynamic Mechanical Analyser and shear rheometry data were shown to be more sensitive than Differential Scanning Calorimetry, Powder X-Ray Diffraction, Scanning Electron Microscope and Fourier Transform Infrared in detecting crystallisation and the interaction between the drug and the polymer. The Dynamic Mechanical Analyser data were consistent with the dissolution behaviour of the samples when comparing the freshly prepared samples with those after storage. The results highlight the need for a unified characterisation approach and the necessity of verifying the homogeneity of mixing during the extrusion process.
    • Study of the Continuous Intention to use Artificial Intelligence Based Internet of Medical Things (IoMT) During Concurrent Diffusion. The Influence Diffusion of Innovation Factors Has as Determinants of Continuous Intention to Use Ai-Based IoMT

      Weerakkody, Vishanth J.P.; Sivarajah, Uthayasankar; Aldhaen, Fatema S.F.A. (University of BradfordFaculty of Management, Law and Social Sciences, 2022)
      This research was about the continuous intention of healthcare professionals to use internet of medical things (IoMT) embedded with artificial intelligence (AI). IoMT and AI are evolving innovations and diffusing at the same time. It was not known in what way the two complex technologies diffusing concurrently could influence continuous intention to use IoMT. In addition, behavioural aspects namely motivation and training to use IoMT have been argued to intervene in the relationship between an AI based IoMT and continuous intention to use IoMT. Diffusion of Innovation theory was applied to explain the relationship between diffusion factors that aid the diffusion of AI based IoMT and continuous intention to use IoMT. The five factors relative advantage, compatibility, complexity, observability and trialability were chosen as determinants of continuous intention to use IoMT using DoI theory. Self-determination theory and theory of planned behaviour were used to introduce the interventions in the relationship between diffusion factors and continuous intention to use IoMT. UTAUT was used to explain the influence of the moderators artificial intelligence awareness, novelty seeking behaviour and age of healthcare professionals. The central issue investigated was the determinants of continuous intention of healthcare professionals to use IoMT with behavioural attributes of motivation and training conceived as mediators of the relationship between diffusion factors and continuous intention to use IoMT in the presence of moderators. Quantitative research methodology was used to test the research model developed to understand the relationship between the five diffusion of innovation theory factors and continuous intention to use IoMT when AI based IoMT is still diffusing. The concurrent diffusion of two new technologies was investigated using a research model that was developed for studying the healthcare professionals and their intention. The research was conducted in Bahrain in the healthcare sector. A sample of 354 healthcare professionals participated in the research. Structural equation modelling was used to analyse the data and test the hypothesis. The research showed that healthcare professionals will continue to use concurrently diffusing technologies depending on the relative advantage, complexity and compatibility of the innovations that diffuse. In addition, the results show that healthcare professionals will be motivated by the compatibility of AI-based IoMT if they have to continuously use IoMT. Furthermore, training enables both the organization and the healthcare professionals to overcome dilemma in case they have to continue to use an innovation during its diffusion or when new innovation surface in the market. Finally, artificial intelligence awareness is able to moderate the relationship between relative advantage, complexity and training to use IoMT. Thus, this research contributes to the discipline of behavioural intention of healthcare professionals in determining the influence of an artificial intelligence based IoMT on continuous intention to use IoMT when artificial intelligence embedded in IoMT diffuses concurrently with IoMT. Where IoMT diffusion factors can be used as a determine of continuous intention to use IoMT, artificial intelligence could be understood as a moderator of the relationship between diffusion factors and training to use IoMT, thus demonstrating the combined diffusion of the two technologies diffusing concurrently.

    • Investigation to Identify the Influence of the Surface Energetics of the Dry Powder Formulations of Budesonide and Theophylline on Their Aerodynamic Dose Emission Characteristics.

      Assi, Khaled H.; Vangala, Venu R.; Jamal, Abdullateef J.A.M.A. (University of BradfordSchool of Pharmacy. Faculty of Life Sciences, 2022)
      Surface energetics play a key role in the delivery of a dry powder inhaler formulation into the lungs, as there must be a sufficient balance of adhesive and cohesive forces to allow optimal lung delivery. In this study, measuring the surface energies of a set of single drug and carrier (budesonide or theophylline with either mannitol or lactose) with different levels of surfactant using Inverse Gas Chromatography, and comparing them to their lung deposition performance using a Next Generation Impactor established a relationship between the two. A 1:10 mixing ratio of budesonide with either carrier was found to have the highest FPF. Coating the carriers with 0.05% sodium lauryl sulphate resulted in a further increase in the FPF when using either budesonide or theophylline as the API, and the same results were seen when a sonocrystallised version of the API was substituted for the micronised form. The calculated IGC values then showed that the highest performing formulations had the lowest dispersive energy and total free surface energy. Furthermore, a trend was observed in the work of adhesion (Wa) and work of cohesion (Wc) for each set of formulations depending on which API was chosen, where for the less polar drug (budesonide) a higher Wa/Wc ratio was associated with the highest formulation performance, and for the more polar drug (theophylline) a smaller Wa/Wc ratio was associated with the highest formulation performance, enabling the estimation of lung performance for a set of single drug and carrier using their surface energy data.
    • An Evaluation of Technological, Organizational and Environmental Determinants of Emerging Technologies Adoption Driving SMEs’ Competitive Advantage

      Sivarajah, Uthayasankar; Rana, Nripendra P.; Vincent, Charles; Dobre, Marius (University of BradfordSchool of Management. Faculty of Management, Law, and Social Sciences, 2022)
      This research evaluates the technological, organizational, and environmental determinants of emerging technologies adoption represented by Artificial Intelligence (AI) and Internet of Things (IoT) driving SMEs’ competitive advantage within a resource-based view (RBV) theoretical approach supported by the technological-organizational-environmental (TOE)-framework setting. Current literature on SMEs competitive advantage as outcome of emerging technologies in the technological, organisational, and environmental contexts presents models focused on these contexts individual components. There are no models in the literature to represent the TOE framework as an integrated structure with gradual levels of complexity, allowing for incremental evaluation of the business context in support of decision making towards emerging technologies adoption supporting the firm competitive advantage. This research gap is addressed with the introduction of a new concept, the IT resource-based renewal, underpinned by the RBV, and supported by the TOE framework for providing a holistic understanding of the SMEs strategic renewal decision through information technology. This is achieved through a complex measurement model with four level constructs, leading into a parsimonious structural model that evaluates the relationships between IT resource-based renewal, and emerging technologies adoption driving SMEs competitive advantage. The model confirms the positive association between the IT resource-based renewal and emerging technologies adoption, and between the IT resource-based renewal and SME competitive advantage for the SMEs managers model, with the SME owners model outcomes are found not being supportive towards emerging technologies adoption driving SME competitive advantage. As methodology, PLS-SEM is used for its capabilities of assessing complex paths among model variables. Analysis is done on three models, one for the full sample, with two subsequent ones for owners and managers, respectively, as SME decision makers, with data collected using a web-based survey in Canada, the UK, and the US, that has provided 510 usable answers. This research has a theoretical contribution represented by the introduction of the IT resource-based renewal concept, that integrates the RBV perspective and the TOE framework for supporting organization’s decision on emerging technologies adoption driving SMEs competitive advantage. As practical implications, this thesis provides SMEs with a reference framework on adopting emerging technologies, offering SME managers and owners a comprehensive model of hierarchical factors contributing to SMEs competitive advantage acquired as outcome of AI and IoT adoption. This research makes an original contribution to the enterprise management, information systems adoption, and SME competitive advantage literature, with an empirical approach that verifies a model of emerging technologies adoption determinants driving SMEs competitive advantage.
    • Historic settlement on Unst, Shetland. An holistic study of abandoned settlements on Unst, Shetland utilising historical archaeology and prospection approaches

      Bond, Julie M.; Gaffney, Christopher F.; Heron, Carl P.; Legg, Robert M. (University of BradfordSchool of Archaeological and Forensic Sciences. Faculty of Life Sciences, 2018)
      A holistic study of abandoned house sites on the island of Unst was conducted to address the extent to which perceptions of historic settlement on Shetland are supportable. These perceptions cast long lived nucleated settlement as the normative traditional form of historic settlement, and dispersed settlements as short-lived exceptions to this norm. Historic settlement, in these perceptions are argued to be static, which is not borne out in archaeological evidence. Issues associated with historic Shetland settlement models were identified to parallel traditional views of Scottish highland rural settlement, which cast the highland society as ahistoric and unchanging. Historical, archaeological and geographic evidence for settlement on Unst were used to assess the geographical distribution of historic settlement on the island. Two detailed case studies integrated archaeological prospection techniques with the historical, archaeological and landscape contexts to form new narratives for the field remains around two abandoned house sites. Assessment of the historical settlement of Unst highlighted a much greater degree of variation between the different evidence strands for the perceptions to truly represent the island’s historical settlement. Similarly, findings from the case studies highlighted a much greater degree of alterations to the field systems and enclosures associated with the settlements than would be anticipated. Alternative narratives with several phases were hypothesised for field remains of each case study.
