Investigating the Site of Newton's Laboratory in Trinity College, Cambridge

It is not generally known that over the course of some thirty years, Isaac Newton carried out around four hundred chemical experiments in a private laboratory located in the walled garden immediately below his rooms in Trinity College, Cambridge. The exact location of his laboratory has long been a source of conjecture and this article describes a survey undertaken to determine both the possible site of the laboratory as well as that of the rubbish pit in which Newton would have disposed of the waste materials generated in his chemical experiments. The results are believed to be of sufficient interest to justify continuation of the investigation

Towards the evolution of style: Einstein’s garden and somewhere between the sky and the sea

The purpose of this research was to explore composition for dance and opera within a collaborative framework. The compositional works were developed after researching modern Australian ballet and opera. Along the journey, I discovered examples of works that were personally inspiring on a number of levels: in the music, text, staging, direction, choreography, scenery, and use of imagery. The elements that resounded with me were then adapted into my own compositions and those elements are responsible for steering my works in a particular direction when it came to performance. I conducted a musical analysis of my contemporary dance work Einstein’s Garden and my chamber opera Somewhere Between the Sky and the Sea, outlining the background and evolution of each work, including compositional stylistic evolution; musical aims; materials and instrumentation; structural plans; choice of tonality; compositional processes and collaboration with the performers; to discussion of the particular staging requirements, and a review of the overall collaboration and production process. In the Einstein’s Garden analysis, I explored the relationship between Albert Einstein, science and music. In the Somewhere between the Sky and the Sea analysis, I studied Portuguese and Spanish music influences on the chamber opera as well as different forms of text setting. I then examined the context of the works and the influence that undertaking musical research had upon my own compositions

Agape and Ecstasy: considering post-secular orientations

This article addresses issues contemporary sexual and religious identity and orientation through an exploration of the unexpected compatibility of post-secular and queer theories

Synchronous reluctance motors with fractional slot-concentrated windings

PhD ThesisToday, high efficiency and high torque density electrical machines are a growing research interest and machines that contain no permanent magnet material are increasingly sought. Despite the lack of interest over the last twenty years, the permanent magnet-free synchronous reluctance machine is undergoing a revival and has become a research focus due to its magnet-free construction, high efficiency and robustness. They are now considered a potential future technology for future industrial variable speed drive applications and even electric vehicles. This thesis presents for the first time a synchronous reluctance motor with fractional slot-concentrated windings, utilizing non-overlapping single tooth wound coils, for high efficiency and high torque density permanent magnet-free electric drives. It presents all stages of the design and validation process from the initial concept stage through the design of such a machine, to the test and validation of a constructed prototype motor. The prototype machine utilizes a segmented stator core back iron arrangement for ease of winding and facilitating high slot fill factors. The conventional synchronous reluctance motor topology utilizes distributed winding systems with a large number of stator slots, presenting some limitations and challenges when considering high efficiency, high torque density electrical machines with low cost. This thesis aims to present an advancement in synchronous reluctance technology by identifying limitations and improving the design of synchronous reluctance motors through development of a novel machine topology. With the presented novel fractional slot concentrated winding machine design, additional challenges such as high torque ripple and low power factor arise, they are explored and analysed - the design modified to minimise any unwanted parasitic effects. The electrical and electromagnetic characteristics of the developed machine are also explored and compared with that of a conventional machine. A novel FEA post-processing technique is developed to analyse individual air-gap field harmonic torque contributions and the machines dq theory also modified in order to account for additional effects. The developed machine is found to be lower cost, lower mass and higher efficiency than an equivalent induction or conventional synchronous reluctance motor, but does suffer higher torque ripples and lower power factor. The prototype is validated using static and dynamic testing with the results showing a good match with finite element predictions. The work contained within this thesis can be considered as a first step to developing commercial technology based on the concept for variable speed drive applications.Financial assistance was provided by was provided by the UK Engineering and Physical Sciences Research Council (EPSRC) in the form of a Doctoral Training Award and additional financial assistance was kindly provided by Cummins Generator Technologies, Stamford, UK, through industrial sponsorship of this wor
