Longitudinally Polarized Photoproduction of Inclusive Hadrons at Fixed-Target Experiments

We present a detailed phenomenological study of spin-dependent single-inclusive high-p_T hadron photoproduction with particular emphasis on the kinematics relevant for the Compass and Hermes fixed-target experiments. We carefully examine the theoretical uncertainties associated with the only moderate transverse momenta accessible in such measurements and analyze the sensitivity of the relevant spin asymmetries to the gluon polarization in the nucleon as well as to the completely unknown parton content of circularly polarized photons.Comment: 12 pages, 14 figures; final version to appear in EPJC; comparison to E155 data and references adde

Disagreement Lost and Found

According to content-relativist theories of moral language, different speakers use the same moral sentences to say different things. Content-relativism faces a well-known problem of lost disagreement. Recently, numerous content-relativists (including the author) have proposed to solve this problem by appeal to various kinds of non-content-based, or broadly pragmatic, disagreement. This presents content-relativists with a new problem—of found agreement. Which (if any) of these newly identified kinds of conflict is correctly identified as the lost moral disagreement we were looking for? This paper offers a critical comparison of different content-relativist proposals. It divides them into two broad categories, quasi-expressivist theories (QED) and metalinguistic theories (MLD). Objections to each are considered, and QED is tentatively found to be superior

Smartphone enabled design: utilising unique markers for re-imagining Ming vases

The conceptual relationship explored is the comparison between this place “here” (A) and this place “there” (B). Each place has specific characteristics that differentiate it from everywhere else. Perhaps most significantly of all, is geographical position; this place (here) and this (an)other place (here) are, by definition, in different locations. Inspired by research into mobile music, which allows for the creative process to take place anywhere, at any time, this paper explores the use of smartphones as a tool for 3D sketching ideas for ceramic vessels. For “In This Place”, the intention is to employ an innovative approach to design, utilising smartphone devices to gather and process location specific data to create a series of unique, singular forms. The resulting digital models can then be 3D printed. As well as exploring a new design process, this allows for a kind of collaboration, as users in different locations contribute to designing the complete series of vessels. Specifically, the aim is to reimagine a ‘pseudo Ming’ dynasty-era vase form, whereby the vessel has a central, vertical division. One half is redesigned by each user “here”, and becomes a unique redesign of the vessel, subtly different to all others designed in their own “here”

Customizing personal objects: a pilot study using a smartphone to "design" a mini vase

This research tests a prototype design application (app) that uses real time sensor data, captured and processed via a smartphone, to generate a series of unique vase forms. Smartphone technology, with the support of embedded sensors, the app, and 3D printing processes, are applied in the design and instantiation of the vases. The users' feedback on the complete process is also examined. The research found that the described design process could be successfully applied to the design, and ultimately manufacture, of unique vase forms. Users stated that the app was easy to use, and allowed them to create intriguing forms they could not otherwise design. While both designers and non-designers found the app usable, they had different expectations from it. This uncovered areas where future iterations of the app could be improved

Found: High Surface Brightness Compact Galaxies

We are using the 2dF spectrograph to make a survey of all objects (`stars' and `galaxies') in a 12 sq.deg region towards the Fornax cluster. We have discovered a population of compact emission-line galaxies unresolved on photographic sky survey plates and therefore missing in most galaxy surveys based on such material. These galaxies are as luminous as normal field galaxies. Using H-alpha to estimate star formation they contribute at least an additional 5 per cent to the local star formation rate.Comment: To appear in "The Low Surface Brightness Universe", IAU Coll 171, eds.

Condition monitoring for airport baggage handling in the area of industry 4.0

Purpose: The findings of a recent study are presented, which was conducted with the objective of addressing the problem of the failure of baggage carts within the high-speed baggage tunnel at Heathrow Terminal 5 through the development of an innovative condition-based maintenance system designed to meet the requirements of 21st century airport systems and Industry 4.0. Methodology: An empirical experimental approach to this action research was taken to install a vibration condition monitoring pilot test in the north tunnel at Terminal 5. Vibration data were collected over a 6-month period and analysed to determine the threshold for good quality tyres and those with worn bearings that needed replacing. The results were compared with existing measures to demonstrate that vibration monitoring could be used as a predictive model for condition-based maintenance. Findings: The findings demonstrated a clear trend of increasing vibration velocity with age, with the wheel mass unbalanced inertia of the carts being transmitted to the tracks as vibration. This research demonstrates that a healthy wheel produces a vibration of less than 60mm/s whereas a damaged wheel measures up to 100 mm/s peak to peak velocity, which can be used in real-time condition monitoring to prevent baggage cart failure. It can also run as an autonomous system linked to AI and Industry 4.0 airport logic. Originality/Value: Whilst vibration monitoring has been used to measure movement in static structures, such as bridges, and in rotating machinery, such as railway wheels (Tondon and Choudhury, 1999) this application is unique as it is the first time vibration monitoring has been applied to a stationary structure (tracks) carrying high-speed rotating machinery (baggage cart wheels). This technique has been patented and proven in the pilot study and is in the process of being rolled out across all Heathrow terminal connection tunnels. It has implications for all other airports world-wide, and also to other applications that rely on moving conveyor belts

How did the publication of the book The Machine That Changed The World change management thinking? Exploring 25 years of lean literature

Purpose The purpose of this paper is to take a critical, analytical approach to explore the growth and spread of lean through the academic and practitioner community over the last twenty-five years. Design/methodology/approach A comprehensive and systematic review of the extant of literature of lean was undertaken. The review spans from 1988 to 2013. To enable us to effectively manage and understand the diffusion of this set of literature a database, the Lean Publications Database (LPD), was constructed. Findings Lean has evolved to be one of the best-known, yet fiercely debated, process improvement methodologies. It emerged during a proliferation of such methodologies in business and management literature. Lean has developed from a generic description of Toyota Production System (TPS) to a particular type of organizational and management intervention focused on best practice and process improvement methodologies. Research limitations/implications This paper provides the first comprehensive review of the Lean literature, from the perspective of Lean as the unit of analysis. It covers both sides of the academic debate and categories the progression of Lean from its origins as a generic description of TPS to a movement that has change management systems in many and diverse sectors. Practical implications This paper demonstrates how Lean research, application and thinking has evolved over 25 years from its origins in explaining the performance improvements in Japanese auto-manufacturing to a holistic value system that is applicable to all business sectors, both private and public. Originality/value This study is original in that provides a different perspective to that of most previous studies. In most empirical studies on Lean, the unit of analysis is the organisation. However, in this study, the unit of analysis is the Lean phenomenon itself and represents a first step to developing an underpinning theory of Lean by linking it to the theory of swift, even flow (Schmenner and Swink, 1998), as such, it of interest to academics in the field of operations management and contributes to knowledge. It is also likely to be of interest to policy makers. Considerable amounts of public money have been spent, and continue to be spent, on promoting Lean. Taxpayers and policymakers are likely to be interested in whether that expenditure is justifiable. Twenty-five years of publications have been analysed to provide clarity around this popular approach to improvement
