Highway Code (Manchester 10k)
No full textHighway Code (Manchester 10k) is a short artists’ film centring around an urban area of Manchester during and after the annual 10km public run. The project investigates how rhythms of the city (such as traffic light signals) can be utilised in determining the rhythmic structure of the film, by tracing these rhythms onto the edit of the film. The film develops methods of editing, collaging and montaging differing views of place that utilise the rhythms of the city in order to realise this effect. Through this use of the city’s rhythms, in combination with the editing process, the city can be seen to partially determine the structure of the film and, to an extent, co-author or contribute to the work
'Blue–Red' (Artwork exhibited in two group exhibitions, 'I Don't Love Soccer Because Soccer Has Never Loved Me'; 'Aaaah', London)
No full textA photographic documentation of a walk from Manchester City’s Etihad Stadium to Manchester United’s Old Trafford stadium. The photos focus on objects around each ground, objects that reflect the colour of the respective teams: blue street signs, walls and bin bags around the Etihad; red cars, doors and bridges around Old Trafford. Some of the connections are arbitrary, some symbolic; some we cannot be sure

No full textSouth Stack
No full textSouth Stack is a short artists’ film that explores the rhythm and life of a building: South Stack lighthouse situated in Ynys Môn (Anglesey), Wales. The film utilises fixed-point filming methods (also known as time-lapse or rephotography), to document the same location at varying times of day, with these images then edited together according to a key rhythm of the lighthouse: the ten-second cycle of the rotating light atop the lighthouse. Through the process, this rhythmic element of the lighthouse – the rotating light – and the light of the sky and surrounding environment are interwoven through the film. The film utilises techniques more commonly used to analyse and document urban and city locations (often known as 'city-film') and applies them to a building situated in a rural location. Ultimately, the work asks: can the life of a building can be apprehended
Grapes Cap Horse Queen
No full text‘Grapes Cap Horse Queen’ (or GCHQ) is an artist book that explores the use of initialisms in a critical manner; how government organisations use initialisms as a part of their linguistic code. The work highlights the use of these initialisms in a playful manner, by presenting them in the form of a children’s alphabet book (A for Apple, B for Balloons, C for Cap, etc). In doing so, a contrast is created between the use of poetic linguistic techniques by these power structures and the child-like way they are presented in the publication. A starting point for the trajectory of the work was a scene from the Cary Grant movie, ‘I Was a Male War Bride’. In a classic scene from the film, the use of government initialisms is parodied by Grant as he tries to decode various government initialisms and acronyms. In the publication, this scene acts as a point of departure
Secondary Processing of Aramid With Awj and Optimization With Nsga-Iii
No full textThe secondary operations of composite parts are performed following thermal cure processes, which generate the final dimensions with desired tolerance and quality specifications. High-strength composites, on the other hand, especially aramid fiber-reinforced polymers (AFRP), are not suitable for conventional machining operations due in part to high operational costs and limited surface quality characterized by fuzziness and delamination. Abrasive Water Jet (AWJ) has been recently shown promising results in obtaining improved surface quality while ensuring significant cost advantages. This study investigates the AWJ processing of AFRP by implementing the analysis of variance and response surface methods. The effects of the control parameters (sand ratio, pressure, stand-off-distance, and feed rate) on the surface quality metrics (surface roughness, kerf angle, and dimensional error) are identified and comparatively evaluated. The surface quality of the AWJ processed AFRP specimens are investigated using Scanning Electron Microscopy (SEM). The trade-offs between the measured tolerances and surface roughness values are identified via a new genetic algorithm approach: Non-dominated Sorting Genetic Algorithm (NSGA-III). Also, operation regions are determined using the generated Pareto curves while improving the quality of various features of an AFRP component, critical to its functional performance during extended service life. As a result, the lowest Ra values obtained were 4.135 mu m for trimming, 5.962 mu m for pocketing, and 4.696 mu m for the hole-making operation. The maximum error in the accuracy of operating regions yields to 7% with independent measurements for validation.Turkiye Bilimsel ve Teknolojik Arastirma Kurumu [118M027]The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by the Turkiye Bilimsel ve Teknolojik Arastirma Kurumu, (grant number 118M027)
Performance Enhancement of Abrasive Waterjet Cutting
No full textAbrasive Waterjet (AWJ) Machining is a recent non-traditional machining process. This technology is widely used in industry for cutting difficult-to-machine-materials, milling slots, polishing hard materials etc. AWJ machining has many advantages, e.g. it can cut net-shape parts, no heat is generated during the cutting process, it is particularly environmentally friendly as it is clean and it does not create dust. Although AWJ machining has many advantages, a big disadvantage of this technology is its relatively high cutting cost. Consequently, the reduction of the machining cost and the increase of the profit rate are big challenges in AWJ technology. To reduce the total cutting cost as well as to increase the profit rate, this research focuses on performance enhancement of AWJ cutting with two possible solutions including optimization in the cutting process and abrasive recycling. The first solution to enhance the AWJ cutting performance is the optimization of the AWJ cutting process. As a precondition, it is necessary to have a cutting process model for optimization. In order to use that model for this purpose, several important requirements are given. The most important requirement for such a model is that it can describe the âoptimum relationâ between the optimum abrasive mass flow rate and the maximum depth of cut. To develop a cutting process model which can be used for the AWJ optimization, many available models have been analyzed. Since the most important requirement for a process model (see above) can be obtained from Hoogstrate's model, an extension of this model is carried out. The extension model consists of three sub-models including pure waterjet model, abrasive waterjet model and abrasive-work material interaction model. The extension cutting process model is more accurate than the original one and it is capable to optimize AWJ systems. The influence of many process parameters, the work materials, the abrasive type and size have been taken into account. Up to now, there has not been a model for the prediction of AWJ nozzle wear. Therefore, modeling the nozzle wear rate has been carried out and a model for the wear rate of nozzles made from composite carbide has been proposed. Based on the extension cutting process model, two types of optimization applications have been carried out. They are related to technical problems and economical problems. From the results of these problems, regression models for determining the optimum nozzle exchange diameter and the optimum abrasive mass flow rate for various objectives have been proposed. The other solution to enhance the cutting performance is abrasive recycling. In this study, GMA garnet, the most popular abrasives for blast cleaning and waterjet cutting, has been chosen for the investigation. The recycling of GMA abrasives has been investigated on both technical side and economical side. On the technical side, the reusability and the cutting performance of the recycled and recharged abrasives have been analysed. The influence of the recycled and recharged abrasives on the cutting quality was studied. On the economical side, first, the prediction of the cost of recycled and recharged abrasives was done. Then, the economic comparisons for selecting abrasives have been carried out. In addition, the economics of cutting with recycled and recharged abrasives have been studied. Several suggestions for an abrasive recycling process which promises a more effective use of the grains have been proposed. By optimization in the cutting process and by abrasive recycling, the cutting performance can be increased, the total cutting cost can be reduced, and the profit rate can be enlarged considerably. Consequently, the performance of AWJ cutting can be enhanced significantly.Civil Engineering and Geoscience
