The calculation of noise from railway bridges and viaducts
No full textPandrol Rail Fastenings Limited are a designer and manufacturer of railway rail-fastening systems. As an organisation they have the capability to reduce the noise impact of bridges using resilient track components. They also have a commercial interest in providing such technology. Knowledge of the processes behind bridge noise is important to Pandrol in two ways; to aid the engineers within the organisation in the design of fastening systems and to demonstrate a state-of-the-art understanding of the problem of railway bridge noise to customers, as this will aid in the sale of Pandrol products. The fitting of new rail components to an existing track form, or failure to meet noise regulations with a new track form, can be costly. It is important to be able to predict accurately the effectiveness of noise reduction techniques. Currently, Pandrol’s knowledge of the problem consists almost entirely of experience gained and data gathered while working on existing bridge projects. To expand their knowledge base, Pandrol perform noise and vibration measurements on railway bridges and viaducts and then use the measured data to predict the performance of their systems on other bridges. This completely empirical approach to predicting bridge noise is both costly and situation specific results cannot be provided before the installation of the fastening system. Another approach to predicting bridge noise is through the application of analytical models. Limited analytical modelling in the context of bridge noise is currently conducted within the organisation. For these reasons, Pandrol are sponsoring research into bridge noise in the form of this EngD project. Here an existing rapid calculation approach is identified that relies less on the exact geometry of the bridge and more on its general characteristics. In this approach an analytical model of the track is coupled to a statistical energy analysis (SEA) model of the bridge. This approach forms a suitable basis from which to develop a better model here by concentrating on its weaknesses. A mid-frequency calculation for the power input to the bridge via a resilient track system has been developed by modelling the track-bridge system as two finite Timoshenko beams continuously connected by a resilient layer. This has resulted in a power input calculation which includes the important effects of coupling between the rail and bridge and the resonance effects of the finite length of a bridge. In addition, a detailed study of the frequency characteristics of deep I-section beams has been performed using Finite Element, Boundary Element and Dynamic stiffness models. It is shown that, at high frequencies, the behaviour of the beam is characterised by in-plane motion of the beam web and bending motion in the flange. This knowledge has resulted in an improved calculation for the mobility of a bridge at high frequencies. The above improvements are included in an improved model for use by Pandrol in their general activities. Data from real bridges is compared to predictions from the improved model in order to validate different aspects of the model. The model is then used to study the effect on noise of varying many bridge design parameters. It is shown that the parameter that has most influence on the noise performance of a bridge is the dynamic stiffness of the resilient rail fastening system. Additionally it is demonstrated that for a given bridge and noise receiver location, an optimum fastener stiffness exists where the noise radiated by the bridge and track is at a minimum

Manzanar camp map, "Manzanar, a photograph essay"
No full textA map of "Manzanar Relocation Center" reproduced from "Manzanar pilgrimage program" by hand by Chris S. Uyemura. The caption reads, "General plan of the W.R.A. Camp at Manzanar, California. Chris Uyemura Collection." A page from: Manzanar, a photograph essay (csudh_uye_0001).The Chris S. Uyemura Manzanar Photograph Collection consists of a pictorial essay, “Manzanar, a photographic essay,” and additional loose photos, which were compiled and collected by Chris S. Uyemura. The essay contains photographs, texts, and newspaper clippings, and was submitted to Professor Donald T. Hata of the Department of History at CSU Dominguez Hills. The collection depicts the incarceration of people of Japanese ancestry in the Manzanar camp during World War II as well as reflects the events, contrasting with photographs of the Manznar National Historic Site, which illustrates what is left of the camp today. The collection was originally named as “Asian Pacific Studies Collection Box 14.

Intimacy Unguarded: Chris Kraus
No full textThe Central Saint Martins research project 'Intimacy Unguarded', run by Emma Talbot and Dr Jo Morra, hosted a visit to Central Saint Martins by United States author Chris Kraus. Kraus is a highly respected writer (I Love Dick, Summer of Hate, Aliens and Anorexia etc) and editor of the semi-texte series 'Native Agents'. In this event, Kraus gave a reading from 'I Love Dick' and was then interviewed by Emma Talbot, to a live public audience.
'Intimacy Unguarded' also ran a seminar called 'Write A Letter To Chris Kraus'. Mirroring the format for the celebrated book 'I Love Dick', in which Kraus uses the letter as a way of addressing a particular figure (with whom she is obsessed) whilst simultaneously unpacking her own personal thoughts and research, participants were invited to 'Write a Letter To Chris Kraus'.
Chris Kraus was present at the seminar, where letters were read aloud and Kraus was the first respondent. Those taking part were from Raven Row, CSM BAFA, MAFA and Afterall. An excerpt from Kraus's book and a selection of the letters will be published in the June 2017n issue of Journal of Visual Art Practice, to be guest-edited by Talbot and Morra
Responding to Literature Through Student–Author Interviews: Eighth-Grade Students Challenge Chris Crowe’s Mississippi Trial, 1955
No full textThis study explores virtual, student–author interviews eighth-grade students led with Chris Crowe in response to his young adult novel Mississippi Trial, 1955. The opportunity to interview the author motivated students to read the novel. Through their text-world development, students connected with the fictional and nonfictional characters, Hiram Hillburn and Emmett Till, respectively. Through their critical reader-responses, students sought truth about Emmett Till’s case as they questioned Crowe about the choices he made as an author and researcher, which supported students’ understanding of character development and historical significance of Emmett Till’s case. Crowe’s answers to the students’ critical questions were not easy, but through the student–author interview preparation and implementation process, participants captured a shared understanding of Emmett Till’s case and how its connection to the U.S. civil rights movement impacted history and is pertinent today. Ultimately, this article advocates for reader-response pedagogy to include virtual or in-person student–author interviews

'We always come here': investigating the social in social learning
No full textThis paper investigates student choices around the 'Third Space' for learning; that which is not either a teaching space or a private space. In mapping the use of such spaces around the University of Northampton's campuses and through the use of semi-structured interviews with students as they use the spaces it constructs a model to help understand why students choose a particular space to work in and influence decisions in the deliberate creation of such spaces in future.
The research shows four, often overlapping, influences on student choice of space; resources, environment, social and emotional. That resource rich spaces that allow social interaction and learning to take place in attractive environments are popular should not be surprising but it is the emotional response to space that is of particular interest. Space attachment theory has usually centred on home or places with religious or national symbolism. This paper identifies an element of emotional resonance to areas of the university campus, especially the library, that will warrant further research
