Publication Embargo An investigation into dynamic TLPs for smartphone communication: To facilitate timed response in way finding for vision impaired people(IEEE, 2013-12-11) De Silva, D. H; Murray, IA reliable, high speed and efficient data transfer method is a very important factor in real time Way-finding systems since it requires information with very low latency to discover paths, avoid dangerous situations, identified changes in existing maps and alternative routes. This research will develop models and methods to facilitate bounded timing with minimal latency for way-finding application for vision impaired people. As a result of analyzing the requirements for Way-finding applications, it was noted that some typical behaviours involve relatively small amount of data transfer through networks. Existing Transport Layer Protocols (TLP) are not ideal for providing such requirements. This research investigates existing TLPs and proposes modifications / extensions to facilitate demands in Way-finding applications and will implement the Dynamic TLP to incorporate both reliable data transfers with high efficiency as well as frequent data transfers which do not require reliability.Publication Embargo Platform Independent Browser Forensic Tool for Advanced Analysis of Artifacts and Case Management(2021 3rd International Conference on Advancements in Computing (ICAC), SLIIT, 2021-12-09) Dissanayake, D.; Rajakaruna, S.; Ranasinghe, D.; Wijesooriya, A.; Jayakody, A.; Rajapaksha, S.Abstract—A web browser is a major attack vector which cybercriminals utilize to land in an environment. The evidence related to the malicious browsing activities can be found in the host which gives valuable information related to the case. These digital footprints involve history, cookies, bookmarks, saved credentials and downloads etc. This paper presents a sophisticated tool aiding the conventional manual investigation process from evidence collection to the final v e rdict b y a u tomating h u man dependent functions, resulting a fast and unbiased analysis of browser forensic artifacts. This tool states its unique value over the existing tools by working operating systems independently, collecting all browsing evidence including deleted artifacts and encrypted saved credentials, automatically analysing the reputation of the extracted evidence, integrating evidence collected from different web browsers into a single timeline, and correlating the adjacent distrustful events inside and outside the host. Eventually, this tool calculates a browsing reputation scorecard and creates a profile for the host, condensing the findings g a thered t h roughout the investigation. The paper presents another important methodology to predict the future browsing reputation score based on the past browsing patterns. Furthermore, multiple cases management feature and dashboard provide a concise overview of overall findings to the forensic investigator.Publication Embargo Investment performance and holding periods: An investigation of the major UK asset classes(Palgrave Macmillan UK, 2009-12) Alles, L. A; Murray, LThe objective of this article is to offer further investigation of the practice of investors to concentrate their investments in cash or bonds as they grow older, and their investment horizons decrease. To provide evidence in this regard, we assess the impact of investment horizon by computing returns, risks and end-of-period wealth distributions of the major UK asset classes, over increasing time horizons. We use monthly observations between 1963 and 2005, and our assessment is based on a block bootstrapping technique. This methodology offers an improvement on previous studies, as it facilitates the retention of past time series patterns of returns. It is likely that these patterns will continue into the future. Results show that investment outcomes at short horizons are different to outcomes at longer horizons. Evidence is provided in favour of time diversification, up to a 5-year horizon. Further, we find that the probability of ending with a shortfall in end-of-period wealth decreases as the holding period lengthens. We also find that higher risk asset classes outperform lower risk asset classes and have higher end-of-period wealth for longer holding periods.
