On k-clusters of high-intensity random geometric graphs See

Let k, d be positive integers. We determine a sequence of constants that are asymptotic to the probability that the cluster at the origin in a d-dimensional Poisson Boolean model with balls of fixed radius is of order k, as the intensity becomes large. Using this, we...

Fluctuations of the connectivity threshold and largest nearest-neighbour link See

Consider a random uniform sample χ_n of n points in a compact region A of Euclidean d-space, d ≥ 2, with a smooth or (when d = 2) polygonal boundary. Fix k ∈ N. Let M_k (χ_n) be the threshold r at&#x...

Corrosion behaviour of SiC particulate reinforced AZ31 magnesium matrix composite in 3.5 % NaCl with and without heat treatment See

Magnesium is a lightweight structural material widely utilised in automotive applications. To enhance its mechanical properties, ceramic particulate reinforcement can be incorporated, particularly for wear resistance and high-temperature applications. However, the addition of ceramic particles to magnesium can&...

Synthesis of a novel adsorbent-photocatalytic material using a low energy route and its application to the remediation of water from contamination of 17-α ethinyl estradiol See

Endocrine-disrupting compounds such as 17α-ethinylestradiol (EE2) pose significant risks to aquatic ecosystems and human health, necessitating the development of advanced water purification materials. This thesis presents the synthesis and characterization of a novel composite coating of hydroxyapatite (HAP)&#x...

Autoignition of ammonia-hydrogen mixtures under engine relevant conditions - second law analysis See

Hydrogen addition can enhance ammonia reactivity and improve its ignition characteristics. This study investigates the fundamental mechanisms governing ignition improvement in ammonia and hydrogen mixtures by quantifying exergy destruction during autoignition at a pressure of 5 MPa, temperature of 900 K,&#...

Continuing professional development for social workers: Social worker or organisation LED? Whose choice? See

The thesis investigates social workers’ perspectives on Continuing Professional Development (CPD), focusing on how decisions about CPD are made, who makes them and the facilitators and constraints that govern these choices. The study acknowledges the regulatory requirement since 2021 for social&#...

Learning random geometric graphs, and their applications See

In the Bayesian world, referring to a variable as “random” means that this vari-able – a scalar, tensor, a network, etc. – takes a value with a probability, such that it attains a values that live in the support of this probabilistic distribution. lies in a given...

The Trade-off Between Security and Privacy: An Empirical Investigation Using Pakistani Survey Data See

This study investigates the complex trade-off between security and privacy in the context of Pakistan’s evolving urban landscape with a particular focus on the controversial Safe Cities initiative in Lahore. Despite the growing global interest in smart and safe city frameworks, there re...

Local Power, Global Scores: Effects of Decentralization Reform on Ukraine’s School Graduate Outcomes See

This paper estimates the causal effect of fiscal decentralization and newly gained spending autonomy on educational outcomes in Ukraine. Exploiting the staggered voluntary formation of amalgamated local governments (hromadas) between 2015 and 2020, we use an event-study design applied to student-...
