Demons and Abelian Projection QCD: Action and Crossover

I evaluate S_{APQCD}, the exact action of Abelian projection QCD, using the microcanonical demon method. Starting with a trial action consisting of L=1, L=2, & L=3 LxL plaquettes plus a Smit-van-der-Sijs magnetic monopole ``mass'' operator, I show that coefficients of the L=2 and L=3 plaquettes vanish at all beta_{SU2}. In fact, at strong coupling S_{APQCD} is essentially the 1x1 compact QED action with beta_{U1}=beta_{SU2}/2. Beyond beta_{SU2}>=2, S_{APQCD} gains an exogenous negative 1x1x1 magnetic monopole mass shift. Note that my approach differs fundamentally from the Smit-van-der-Sijs approach in that I do not make an a priori assumption about monopole or plaquette size in S_{APQCD}. Indeed, these results suggest that QCD monopoles are pointlike, in contrast to the ``effective'' condensation picture put forth by Smit and van der Sijs.Comment: to appear in Physics Letters B347 (1995) 367-37

Dynamic literature mapping : typography in screen-based media

This paper chronicles the development of a visual map representing a literature search on key theorists and thinkers in two principal topics: Typography and New Media. Its aim is to visualise and facilitate conceptual connections between key ideas and philosophies across disciplines. This literature map was drawn up by reviewing available influential literature within these topics. Related categories were later added and a further series of literature searches were conducted to build references in each topic. This on-going cyclical process serves to construct a comprehensive contextual map of knowledge. The benefit of the map is twofold. Primarily, aiding the researcher to navigate and understand complex layers of information. Secondly, allowing the researcher to present and share representations of knowledge. The clarity of the representation is crucial in eliciting the participation of fellow design researchers and practitioners to the development and growth of the literature map

Connecting practice to research (and back to practice): making the leap from design practice to design research

This paper explores two questions: what skills and knowledge can be derived from research and brought back into design practice; and how can we better prepare designers to undertake research? Its aim was to enable design practitioners wishing to pursue research to understand the process and anticipate the scope and level of work. Additionally, it addressed the questions of how design education can incorporate a research-based curriculum and how professional bodies can promote the value of research to practitioners? A complementary paper was co-written and presented at the CONNECTED 07 conference, Sydney. It explores the process of undertaking a PhD within the framework of the UK design education system by examining it from a design and business perspective (Yee, J.S.R, Michlewski, K. and Bohemia, E. (2007) 'Interrogating the Academic Research Process in UK Design Education from Design and Business Perspectives', ConnectED 2007 – International Conference on Design Education, Sydney, (http://www.designdictator.com/publications/connected07.pdf). Yee’s research bridges the gap between contemporary design practice, the growth of professional knowledge and pedagogy, via empirical study and theoretical discourse. Yee is currently 2nd supervisor for a PhD, entitled; ‘The Development of a Framework to Understand Potential Relationships Between Services and Their Users’ and is contributing to the development of the Professional Practice Doctorate in Design in the CfDR

Capturing tacit knowledge: Documenting and understanding recent methodological innovation used in Design Doctorates in order to inform Postgraduate training provision

This paper presents a preliminary review of recent Design PhDs that identify and analyse the methodological innovation that is occurring in the field, in order to inform future provision of research training for Design PhDs. Six recently completed Design PhDs are used to highlight possible philosophical and practical models that can be adopted by future PhD design students. Four characteristics were found in Design PhD methodology; thesis-structural innovation, a ‘pick and mix’ research design approach, situating practice in the enquiry and the validation of visual analysis. The paper concludes by offering suggestions on how research training can be improved for Design PhD candidates. By being aware of recent methodological innovations in the field, design educators will be better informed when developing resources for future design doctoral candidates, and assisting supervision teams in developing a more informed and flexible approach to practice-led research

A Typographic Dilemma: Reconciling the old with the new using a new cross-disciplinary typographic framework

Current theory and vocabulary used to describe typographic practice and scholarship are based on a historically print-derived framework. As yet, no new paradigm has emerged to address the divergent path that screen-based typography is taking from its traditional print medium. Screen-based typography is becoming as common and widely used as its print counterpart. It is now timely to re-evaluate current typographic references and practices under these environments, which introduces a new visual language and form. This paper will attempt to present an alternate typographic framework to address these growing changes by appropriating concepts and knowledge from different disciplines. This alternate typographic framework has been informed through a study conducted as part of a research Doctorate in the School of Design at Northumbria University, UK. This paper posits that the current typographic framework derived from the print medium is no longer sufficient to address the growing differences between the print and screen media. In its place, an alternate cross-disciplinary typographic framework should be adopted for the successful integration and application of typography in screen-based interactive media. The development of this framework will focus mainly on three key characteristics of screen-based interactive media ¬¬– hypertext, interactivity and time-based motion – and will draw influences from disciplines such as film, computer gaming, interactive digital arts and hypertext fictions

Experimental study and numerical modelling of woven fabric kenaf fiber composites hybrid adhesively bonded-bolted joints

Couple with natural fiber composite parts, hybrid joints provide better joint strength than using separate joints. There are limited studies on structures response and strength prediction work on hybrid joints that limits its applicability. The aim of present study is to conduct experimental datasets on woven fabric kenaf fiber reinforced polymer (KFRP) and carbon fiber reinforced polymer (CFRP) composite hybrid joints under quasi-static testing and to carry out the strength prediction works subsequently by implementing physically-based traction-separation constitutive law. Testing series investigated includes variation of joint types, normalized W/d = 2 to 5, reinforcing fiber composites, lay-up types, plate thickness and bolt loads. Experimental observations and bearing stress at failures were conducted, the datasets were then used as validation works in FEA modelling. All KFRP hybrid joint series demonstrated net-tension failure mode associated to stress concentration at the vicinity of notch tip. Initially, strength prediction works were attempted by implementing various numerical approaches and fully XFEM techniques was adopted to all series as it provides promising results with better physically representation and less computational time. Good agreements between experimental datasets and predicted bearing stress at failure were found in KFRP hybrid joints with average discrepancy of less than 23%. It was found that combinations of thicker and cross-ply lay-up gives the best prediction of less than 2 % (where experimental datasets and FEA output were given as 201 N/mm2 and 198 N/mm2 respectively) due to better repetitive lay-up with implementation of smeared-out properties. Less significant effects from bolt loads and reinforcing fibers were found for both joint types. It can be concluded that fully XFEM technique able to provide as a unified prediction tools in hybrid joints of most composite materials with reasonable agreements
