Polymer multimode waveguide optical and electronic PCB manufacturing
No full textThe paper describes the research in the £1.3 million IeMRC Integrated Optical and Electronic Interconnect PCB Manufacturing (OPCB) Flagship Project in which 8 companies and 3 universities carry out collaborative research and which was formed and is technically led by the author. The consortium’s research is aimed at investigating a range of fabrication techniques, some established and some novel, for fabricating polymer multimode waveguides from several polymers, some formulations of which are being developed within the project. The challenge is to develop low cost waveguide manufacturing techniques compatible with commercial PCB manufacturing and to reduce their alignment cost. The project aims to take the first steps in making this hybrid optical waveguide and electrical copper track printed circuit board disruptive technology widely available by establishing and incorporating waveguide design rules into commercial PCB layout software and transferring the technology for fabricating such boards to a commercial PCB manufacturer. To focus the research the project is designing an optical waveguide backplane to tight realistic constraints, using commercial layout software with the new optical design rules, for a demonstrator into which 4 daughter cards are plugged, each carrying an aggregate of 80 Gb/s data so that each waveguide carries 10 Gb/s

Heeding the great commission: The significance of Matthew's gospel for Baptismal theology and practice in a post-Christian age.
No full textThis thesis represents a worked example in the application of Scripture to a contemporary theological situation. The Scripture applied is Matthew's Gospel and the theological situation is the ongoing practice of Christian baptism by paedo-baptising churches in the context of a post-Christian cultural milieu. Matthew's Gospel is a particularly relevant text with respect to baptism as the church traditionally has cited the baptismal command of Matthew 28.19 as a warrant for its baptising activity. The interpretation of Matthew m this thesis has emerged from a reflection on practice and is also directed back towards practice. The notion of 'performance’, therefore, is regarded as an especially helpful metaphor for interpretation: the believing community 'performs' its Scripture as a company of players would perform a play or a musical score. The formulation of this metaphor in the work of Kevin J. Vanhoozer is particularly utilised m the thesis. Vanhoozer suggests that Scripture testifies to the dramatic saving activity of God (the theo-drama) in which the church is called to participate. Therefore it is important to understand the plot of the drama as it is communicated m Scripture so that the church can work to continue the action faithfully. As such this thesis functions as a case study in 'performance' hermeneutics and will be of interest both in the academy and in the church. In terms of exegesis, therefore, this thesis is concerned with the place of baptism տ Matthew's presentation of the theo-drama. I argue that baptism in the name of the Father, Son and Holy Spirit (28.19), in the context of the Matthean narrative, is a symbol of narrative inclusion for a new disciple. Christian baptism makes connection with key moments in the Gospel such that it declares the gospel of the kingdom whilst enabling a rich expression of repentance and acceptance of a call to discipleship. The theo-dramatic significance of baptism is then considered alongside the challenges of paedo-baptismal ministry in post-Christian contexts. This creative interaction leads to strategies for baptismal performance being imagined that are not only faithful to the Great Commission but which are also culturally meaningful
The Chance and Probability Concepts Project
No full textThis article, created by D.R. Green, describes an investigation of what concepts and intuitions concerning random processes are present in the minds of children of varying abilities across the 11-16 age range. The ability to list permutations, combinations and arrangements is also being investigated. The author states, "Over the past two decades the topic of 'Probabilityâ has been brought into the mathematics curriculum but it may be that this is more an empty gesture rather than a sound strategy." This article can help to alleviate many of the struggles in teaching probability concepts. The article is pitched at a more elementary audience, but is still a perfect resource for almost anyone teaching in the field

Bepalen van het massatraagheidsmoment met behulp van een bifilar pendulum: Determining the moments of inertia using a bifilar pendulum
No full textThe aim of this thesis is to investigate the use of a bifilar pendulum for determining the moments of inertia of the TU Delft solar boat and to quantitatively predict the estimates. In the first part, several methods are discussed which can be applied in deriving the equations of motion of the pendulum. A new method, Kane's method, will be introduced. In the second part, this method will be used to derive the actual equations of motion. These equations are linearized around of the the pendulum's stationary positions to obtain expressions which link the moment of inertia about an axis to the period of oscillation of the pendulum about that axis. These equations are subsequently applied to the solar boat to derive estimates for the moments of inertia about the principle axis of the boat. The results of this thesis considers three different configurations of the bifilar pendulum with the solar boat suspended. One of these configurations results in the most accurate estimates for the moments of inertia, however, these have not been quantitatively predicted. The author suggests a modification in the definition of the bifilar pendulum such that this might be possible.Electrical Engineering, Mathematics and Computer ScienceNumerical analysi
