Technology Anxiety in Virtual Reality Adoption: Examining the Impact of Age, Past Experience, and Cybersickness
No full textThis study examines the role of Technology Anxiety (TA), age, past use, and cybersickness in the adoption of Virtual Reality (VR) technology. Using an extended Technology Acceptance Model (TAM), the research integrates age and past use as antecedents of TA and evaluates their influence on perceived ease of use (PEoU), perceived enjoyment (PENJ), and user attitudes. Data from 206 participants were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) following a VR pilgrimage experience. The findings challenge conventional assumptions, revealing that past VR use increased TA, contradicting prior studies that associate familiarity with reduced anxiety. Additionally, older users exhibited lower TA levels than younger participants, highlighting a potential shift in how age influences technology adoption. TA significantly enhanced PENJ, indicating that anxiety may amplify emotional engagement in immersive settings, rather than solely acting as a barrier. While TA enhanced PEoU, it had a negative correlation with cybersickness, suggesting that anxious users might interact with VR more cautiously, thereby limiting sensory mismatches. Moreover, cybersickness did not significantly influence attitudes toward the system, emphasizing the dominance of engagement over physical discomfort in emotionally significant experiences. Attitude toward the system strongly predicted use intention, highlighting the necessity of designing VR experiences that balance usability with emotional engagement. This study provides new insights into the psychological and demographic factors influencing VR adoption and offers practical strategies for optimizing user experience, particularly in religious and cultural applications

Thus, our study will propose an analysis of the ideological and historical dimension of this text representative of the literary experience of the author, then at the end the questioning of his human and moral values
Development of battery-supercapacitor management systems for electric vehicles
No full textThis thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonThe electric vehicle (EV) sector is rapidly advancing, representing a global shift toward sustainable, eco-friendly transportation. With an increasing focus on reducing carbon emissions and reliance on fossil fuels, EVs have become central to achieving environmental goals. However, widespread adoption is challenged by current limitations in energy storage, efficiency, and reliability. This thesis introduces an innovative hybrid energy storage system (HESS) tailored for EVs, integrating both batteries and supercapacitors to overcome these limitations. At the core of this HESS lies a battery management system (BMS) responsible for monitoring, optimising, and sustaining battery health and performance. The BMS is critical for ensuring safe operation, extending battery life, and maximising energy efficiency across a range of operational conditions.
This study tackles three principal difficulties in electric vehicle energy management: the efficient integration of HESS, operating stability, and improved efficiency under varying driving situations. The research examines various battery types, such as lead-acid, nickel-cadmium, nickel-metal-hydride, and lithium-ion, evaluating each for energy density, power output, lifespan, and charging efficiency. Lithium-ion batteries, commonly utilised in electric vehicles for their high energy density and consistent performance, are assessed for their compatibility with supercapacitors in hybrid energy storage systems. Supercapacitors, recognised for their quick charge-discharge capabilities and enhanced power density, augment lithium-ion batteries by alleviating stress during peak power demands. The resultant HESS design integrates the advantages of both components, providing a system that enhances efficiency while ensuring sustained performance and dependability in electric vehicles. A novel contribution of this research is the development of a fully active HESS topology, capable of dynamic energy allocation to reduce stress on the battery and SC.
Three common driving cycles were used in the simulations, including Artemis Rural, Artemis Motorway, and US06, to reflect varied driving situations. The simulations were performed using MATLAB/Simulink. In comparison with Proportional-Integral (PI) and Model Predictive Control (MPC) approaches, the results show that the Radial Basis Function (RBF) controller optimises energy flow and maintains system stability significantly. The RBF controller obtained a battery State of Charge (SOC) of 78.86% with the HESS in the Artemis Rural cycle, which is far higher than the 64.41% and 64.2% SOCs achieved by the MPC and PI controllers, respectively. In comparison to the MPC controller's 99.28% and the PI controller's 99.14% SOC, the RBF controller achieved a minimal SOC loss of 99.69% during the Artemis Motorway cycle. The RBF controller outperformed the MPC controller at 72.75% and the PI controller at 70.2% in the demanding US06 cycle, which is characterised by rapid acceleration and deceleration, by maintaining a SOC of 82.91%. Moreover, the RBF controller obtained a substantial energy savings of 3.09 kWh in the US06 cycle when contrasted with the PI controller. The RBF controller is the most effective strategy for optimising HESS performance across a variety of operating conditions, as these results demonstrate.
The findings emphasise the HESS's ability to mitigate battery stress, optimise energy recovery, and ensure stable performance across varied driving conditions. The HESS minimises energy losses, enhances energy recovery efficiency, and extends battery lifespan by dynamically allocating energy between the battery and supercapacitor. These results establish benchmarks for the integration of HESS in EVs, contributing to sustainable transportation solutions.EPSRC Doctoral Training Progra

Agosti. 1 ☿, Sharjah Desert Park, 5–6.x.2004, AvH; 1 ☿, 3.iii.2005, CAC. 1 ☿, al- Za'aba, 100 m, sandy soil with Rhaisa stricta [23°43'20"N, 55°33'49"E], 22.iii.1995, leg. D. Agosti. Description: A large worker from al-Ain was selected as holotype. The measurements are as follows: total length 8.40; head width 3.60; head length 4.20; scape length 3.84; funicular segment I 0.40; funicular segment II 0.23; petiole length 1.10; petiole width 0.72. Colour dark reddish brown. There are no exterior hairs on the scapes or hind tibia. The gaster, petiole and propodeum have dorsal hairs. Remarks: This species thought to correspond with C. desertorum has to be described as a new species. In fact it is one of the commonest Cataglyphis in southern Arabia. The main distinguishing feature compared with other dark Cataglyphis is the slender petiole, which has the anterior face more sloped than in other similar species such as C. niger (André, 1882) and C. savignyi (Dufour, 1862). Biology: Cataglyphus laylae nov. spec. does not appear to occur in open sandy desert and is most abundant in disturbed habitats such as man-developed plantations and open cultivated fields. Distribution: This species was recorded by Collingwood (1985) as C. desertorum from Saudi Arabia and Oman and as Cataglyphis spec. by Collingwood & Agosti (1996). Etymology: The new species is named after a village settlement called “Layla”, just north of Riyadh (Saudi Arabia) in the area where the author (CAC) first encountered it in numbers in an Acacia plantation.Published as part of Cedric A.

Digital amplification for pathogen detection in bloodstream infections from whole blood
No full textSensitive and specific detection of bacteria is essential for control and treatment of bloodstream infections. Sepsis, a diagnostic challenge of blood stream infections, causes thousands of deaths each year. The gold standard for detection and identification of microorganisms is blood culture, which can take up to 5 days to yield a diagnosis or a negative result. Molecular diagnostic methods and nucleic acid assays developed to detect pathogens often require enrichment through blood culture prior to DNA extraction. Nonetheless, state of the art diagnostic tests that detect pathogens directly from blood are available with limitations. Increased amount of sample processing and purification is required before detection of pathogens and turnaround time to results can be up to 8 hours. Moreover, the sensitivity and specificity of such assays are broad in range. Thus, there is a need for a rapid detection method that can identify pathogens from whole blood within 1-2 hours, with minimal sample processing and high sensitivity and specificity.
In this work, we demonstrate detection of bacterial pathogens from whole blood through loop mediated isothermal amplification without the steps of DNA purification and extraction. Whole blood with pathogens is dried to tubes, creating separated phases of the cellular debris of blood from the amplification reaction and allowing for separation of background human DNA from target DNA as well as better detection of amplicons that are not masked by red blood cells. We show that this method is robust, having a detection limit of 1 cfu of pathogens in 4uL of whole blood. In preparation of processing higher blood volumes in a digital amplification method, we also show characterization experiments and preliminary results of amplification of pathogens from whole blood on chip.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-12-01The student, Ariana Mostafa, accepted the attached license on 2019-12-04 at 05:15.The student, Ariana Mostafa, submitted this Thesis for approval on 2019-12-04 at 05:29.This Thesis was approved for publication on 2019-12-05 at 09:04.DSpace SAF Submission Ingestion Package generated from Vireo submission #14686 on 2020-02-28 at 17:23:14Made available in DSpace on 2020-03-02T22:15:06Z (GMT).

Interreligiöse Kompetenzen islamischer Religionslehrer*innen an den AHS in Niederösterreich
No full textDie Gesellschaft in Österreich gestaltet sich pluralistisch und vielfältig. Dabei ist das Verständnis für den Anderen und das Fremde oft nicht vorhanden. Die Schule soll Werte wie Achtung und Wertschätzung vermitteln können. Die islamischen Religionslehrer*innen stehen damit vor großen Herausforderungen, wie in der täglichen Praxis festzustellen ist.
In der vorliegenden Arbeit werden zum einen die interreligiösen Kompetenzen und zum anderen die Bedingungen, um diese zu erwerben, ausgearbeitet. Sie besteht aus zwei Teilen und beinhaltet einen theoretischen und einen empirischen Abschnitt. Basis dieser Ausarbeitung sind vier Interviews mit islamischen Religionslehrer*innen an den höheren Schulen in Niederösterreich und deren Auswertungen.
