In the first part of this paper, the Kriging metamodeling technique will be briefly reviewed. Then, we present a new learning function by accounting for the distance constraint in the selection process of the new training points (TPs) to enrich the Design of Experiment (DoE) of the built surrogate.

This study seeks to examine (1) the impact of crisis timing strategies (stealing thunder and thunder) on responsibility and (2) explore the role of involvement in the crisis communication field. The experiment employees a between-subjects design and utilizes a fictitious crisis scenario to collect data from 300 participants. The results show that the use of stealing thunder to mitigate crisis damage is much more beneficial to organizations than thunder.

Fashion design education does not have a very long history in Sri Lanka. But the institutes have completed considerable number of years to review their curriculum approaches to revise for future trends and demands. At present, so far locally qualified fashion designers are applying fashion design in many unique ways according to each individual’s need. This research will identify their experience and practices. In doing so, the research will assist to understand the current position of the fashion designer within Sri Lanka’s fashion industry system to address the key research questions.

This thesis investigates the SPH capability available in the commercial Finite Element (FE) code LS-DYNA®, for water impact problems. Experiments have been conducted on rigid wedges impacting water, which were then simulated with the SPH method. Although certain limitations were experienced with the experimental results, a positive correlation was observed with the numerical technique, thus establishing SPH as a promising method for crashworthiness design.

In the last 10 years interest and activity in urban sonic design has expanded. The way we listen to, think about and understand sound determines the way we value, manage and design with it. However practitioners in the area would benefit from detailed forms of site documentation and analysis that go beyond physical sound measurement. This Masters explores the use of the Sonic Identity Model developed by Pascal Amphoux of CRESSON (the Centre for Research on Sonic Space and Urban Environment) in the early stages of urban sonic design.

This research investigates the interactive effects of usability, the designer perspective and user expectations on the user experience (UX) of e-commerce websites. It incorporates the theoretical underpinnings of Norman’s (1988) seminal research specifically, Mental Models and Nielsen’s User Categories (1993) to explore the different mental models, domain and technology expertise of two distinct groups – users and designers – in the interaction with a selected system image, that of the e-commerce website.

This research examines how parametric loudspeakers may be considered unique acousmatic musical instruments; how the parametric acoustic array (PAA) can potentially make new forms of music and listening experiences; and how PAA-design problems can be overcome. Interdisciplinary in nature, the study uses grounded theory and experimental music practice within a design research methodology. Theory emerges from data, in concert with analysis and framing that draws on areas such as electroacoustic music, spatial composition, acoustics, PAA science/theory, modulation theory, and medium theory.

This dissertation presents a creative practice-based experiment in civil celebrancy with the focus on contemporary celebrancy. The dissertation constructs and reflects upon a Ceremony of Restoration to give meaning, healing, and mending for people’s lives in the wake of traumatic, chaotic, and unresolved events. This ceremony can be used by the person, or people, at its centre to give expression to such experiences and feelings and to build resilience through a secular ritual involving their stories, memories, images, personal artefacts, and music.

Let’s Play videos are the practice whereby a videogame player records their experience to share with a future audience. They are an emergent form of cultural activity that has been relatively overlooked within the field of game studies. This thesis seeks to ask: how can access to videogame play moments (and performativity) provide insights into the understanding the dynamics of videogame play experience? This thesis approaches Let’s Play videos as a way in which to expand our understandings of videogame research.
