Advancing User Authentication And Access Management, Jeffery Crume
School of Engineering, Computing and Mathematics Theses
In order for online systems to transact business or exchange other sensitive information, there must be an environment where the parties involved can verify that the other is who they claim to be. Authentication mechanisms provide this verification process, thereby, improving confidence in the confidentiality and integrity of communications. However, attackers can exploit this trust if they are able to successfully impersonate a legitimate user and gain access to the system with all the rights and privileges of that user. One particularly difficult class of attacks of this sort involves an attacker inserting themselves between the end user and the …

Any delay and only reactive actions to IS incidents put their assets under risk. A properly designed IS incident management system …
The Impact Of Firm Characteristics On Speed Of Adjustment To Target Leverage: A Uk Study, James Fitzgerald, J. Ryan
The Impact Of Firm Characteristics On Speed Of Adjustment To Target Leverage: A Uk Study, James Fitzgerald, J. Ryan
Articles
Responding to the need to investigate heterogeneity in the speed of adjustment (SOA) to target leverage in a manner that reflects the fractional nature of leverage, we estimate SOA across sub-samples of UK firms using the Dynamic Panel Fractional (DPF) estimator. Using firm characteristics to identify firms subject to varying costs of deviation from and adjustment to target leverage, we find significant evidence of heterogeneity in the speeds at which UK firms adjust to target leverage. Our results show that small, high growth and low dividend paying firms adjust to target leverage faster than their large, low growth and high …

Lead Pollution Of Coastal Sediments By Ceramic Waste, Andrew Turner
Lead Pollution Of Coastal Sediments By Ceramic Waste, Andrew Turner
School of Geography, Earth and Environmental Sciences
© 2018 Ceramic fragments and fractionated (<2 mm) sediment have been sampled from two beaches in southwest England, along with sediment from a control beach where ceramic waste was lacking. Analysis of the glazed ceramic surfaces by X-ray fluorescence (XRF) spectrometry returned concentrations of Pb up to 729,000 mg kg−1, while XRF analysis of sediment samples revealed high but heterogeneous concentrations of Pb at the two sites impacted by ceramic waste (median = 292 and 737 mg kg−1) compared with the control beach (median ~ 20 mg kg−1). These observations are attributed to the disposal of contemporary and historical ceramic products, and the subsequent attrition of material and contamination of local sediment. Extraction of a milled ceramic composite (Pb = 2780 mg kg−1) by 1 M HCl, revealed a high (34%) environmental mobility and availability of Pb; extraction in a solution of protein, however, suggested a low (0.1%) bioaccessibility to sediment-ingesting invertebrates.
An Object-Based Multimedia Forensic Analysis Tool, Shahlaa Talib Mashhadani
An Object-Based Multimedia Forensic Analysis Tool, Shahlaa Talib Mashhadani
School of Engineering, Computing and Mathematics Theses
With the enormous increase in the use and volume of photographs and videos, multimedia-based digital evidence now plays an increasingly fundamental role in criminal investigations. However, with the increase, it is becoming time-consuming and costly for investigators to analyse content manually. Within the research community, focus on multimedia content has tended to be on highly specialised scenarios such as tattoo identification, number plate recognition, and child exploitation. An investigator’s ability to search multimedia data based on keywords (an approach that already exists within forensic tools for character-based evidence) could provide a simple and effective approach for identifying relevant imagery. This …

APPs were heterogeneously distributed, with maximal concentrations of 430 particles L −1 (0.2 g L −1 ) near to a facility where boats are regularly maintained and 400 particles L −1 (4.2 g L −1 ) at a location where old boats had been abandoned, with the majority of particles encountered in the finest size fraction retrieved. APPs contained variable concentrations of Cu, Zn, Sn and Pb, with …
Improving Group Integrity Of Tags In Rfid Systems, Reem Alkanhel
Improving Group Integrity Of Tags In Rfid Systems, Reem Alkanhel
School of Engineering, Computing and Mathematics Theses
Checking the integrity of groups containing radio frequency identification (RFID) tagged objects or recovering the tag identifiers of missing objects is important in many activities. Several autonomous checking methods have been proposed for increasing the capability of recovering missing tag identifiers without external systems. This has been achieved by treating a group of tag identifiers (IDs) as packet symbols encoded and decoded in a way similar to that in binary erasure channels (BECs). Redundant data are required to be written into the limited memory space of RFID tags in order to enable the decoding process. In this thesis, the group …
