Abstract:

The collection of extended and updated abstracts presented here resulted from a two-day workshop of the Collaborative Research Centre ‘Interactions between and Modelling of Continental Geo-Systems’ (SFB 350) held on 19thand 20thNovember, 1999 at the Rheinische Friedrich-Wilhelms-Universität Bonn. This workshop was entitled ‘Rift Tectonics and Syngenetic Sedimentation - the Cenozoic Lower Rhine Graben and Related Structures’. Its central topic was devoted to various approaches of understanding the evolution of a young graben structure, with the aim to trace the interaction of tectonics, sedimentation, facies development, burial history, and coherent structural behaviour by integration of geodetic, seismological, gravimetric, sedimentological, paleontological, and climatological data.

Abstract:

In the last years new methods of data acquisition and processing in geosciences, inspired by growing computer performance, have led to an increased amount of data, and this development will proceed surely. In this paper we present the conception and technical realization of an interdisciplinary research group's geodata management as a combination of a metadata catalog together with web mapping technology. Clearly related with the storage and retrieval of different datasets is the need of visualization. 3D visualization in geoscientific interpretation is a useful tool, if numerous, heterogenic datasets have to be visualized at the same time. Moreover, advanced sensing technology often generates native three-dimensional datasets. Using a case study from the Collaborative Research Centre “SFB 574”, we present the possibilities of our stereoscopic projection system and want to explain the benefit of 3D visualization for research in general and university education in particular, as low-cost systems become available nowadays.

Abstract:

AbstractAdaptive buildings constitute an interdisciplinary approach for realizing the next generation of buildings in order to reduce the immense material requirements and energy demand throughout all lifecycle phases. Based on a novel cooperation between the disciplines of Architecture and Civil and Mechanical Engineering, adaptive support structures and skins are developed within the Collaborative Research Centre SFB 1244. A holistic planning process is required in order to reduce the high complexity and achieve a goal-oriented procedure during the planning of such buildings and the development of integrated systems.Part of this research is the development of new specific and the transfer of established methods from different disciplines. The experience gained during the planning of an adaptive, high-rise demonstrator building within the research project has shown that the methods for application must be provided in the form of a method toolbox to present their purpose, application time and results within the planning team. Based on the examination of existing method toolkits, this paper focuses on the development of an approach while considering context-specific requirements.

Abstract:

The importance of rigid and self supporting space frame structures for the automotive and aerospace industry continually increases. To meet the market requirements for a flexible and competitive small batch production, innovative machine concepts must be investigated. By integrating handling and machining capabilities into one machine structure, redundant degrees of freedom can be reduced and a former idle economic potential can be made use of. This paper introduces a systematic approach to reveal synergetic potentials that emerge by integrating two different fields of function, the handling and the machining. Therewith a matrix with technical solutions for a combination of handling and machining is generated. These solutions are the base for new machine concepts that fulfill both tasks with a minimal number of machine axes. The authors present a machine concept which is combined out of a four-axes parallel kinematics and a conventional serial kinematics. The two kinematic structures collaborate and allow the product flexible handling and machining of three dimensional rounded extrusions with a minimal technical effort. The machine concept is dimensioned and optimized for a maximal stiffness by the coupling of a multi body simulation to an external parameter optimization software. The optimization results show that the stiffness of the machine concept could be explicitly improved. This paper is based on investigations of the collaborative research centre SFB/TR10 which is kindly supported by the German Research Foundation (DFG).

Abstract:

The prototype for the flying cutting of spatially curved extrusion profiles developed as part of the Collaborative Research Center Transregio 10 (SFB/TR 10) was tested as an integrated part of the overall system in first test runs. The profiles resulting from this process give proof of the potential involved in both, the novel curved profile extrusion (CPE) and the automatic supporting and cutting device. For subsequent automated processing to become possible, however, the reliably achievable accuracy of extruded profiles needs to be further improved. By the example of the extruded profiles produced so far, this article discusses potential factors that may impair profile accuracy and presents approaches and methods for the improvement of accuracy.

Abstract:

The present work has been executed within the framework of the collaborative research center on Distortion Engineering (SFB 570) in order to evaluate the residual stress state of a disc after carburizing and quenching as well as to validate a simulation procedure. The combined use of X-ray and neutron diffraction analysis provided information about the residual stress states in the whole cross section. However, the stress free lattice spacing d0 for the neutron diffraction experiments is problematic and induces systematic uncertainties in the results and the application of a force balance condition to recalculate d0 might be a solution for improving the reliability of the results. Comparison of experimental results with simulation showed that an overall satisfying agreement is reached but discrepancies are still present.

Abstract:

In order to manufacture a workpiece fulfilling specified requirements with the lowest possible weight, it is crucial to be able to work with a variety of materials and to combine them accordingly. The production of profiles based on hybrid materials demonstrates such an approach. The continuous and selective reinforcement of aluminum profiles with metallic elements like steel wire and steel wire ropes by composite extrusion is being investigated within the scope of research of the Transregional Collaborative Research Center (SFB/TR10). A stable production process for composite profiles with embedded continuous reinforcing elements was developed during the research work. In this paper, the process principle is shown and an overview of the special tools is given. Furthermore, the temperature and the strand speed as influencing factors on the final state of the composite are analyzed, based on real size experiments using a 2.5MN and a 10 MN extrusion press.

Abstract:

AbstractAs part of the activities of the Collaborative Research Centre ‘SFB 350’, measurements of geodetic and geodynamic changes in the area of the Lower Rhine Embayment and the Rhenish Shield are being performed at different scales in space and time. Continuous borehole tilt measurements and repeated microgravimetric surveys yield information on the local stability of the ground and changes in horizontal gravity gradients that are both dominated by seasonal fluctuations. Results of more than seven years of regular GPS campaigns are discussed in terms of vertical and horizontal point motions. The most prominent motions are man-induced effects occurring in or near the browncoal mining areas, where groundwater withdrawal produces subsidence of up to 2.2 cm/y in the area under investigation. Horizontal and vertical motions at other GPS points are smaller by one order of magnitude and in most cases are only marginally detectable. The eastward motion of two points in the Bergisches Land and the westward motion of two points in the Eifel near the Belgian border may be interpreted as a result of the ongoing extension of the Cenozoic rift system in the western part of the Eurasian plate.

Abstract:

This investigation describes the development and evaluation of thixoformable alloys on Al-Li-Mg basis in the scope of the collaborative research center SFB 289 at RWTH Aachen University. Scandium and zirconium was added to Al-Li2.1-Mg5.5 (A1420) with the aid of DoE (Design of Experiments) and precursor billets were manufactured by pressure induction melting (PIM). To evaluate the thixoformability of the synthesized alloys high-quality semi solid processed demonstrators were manufactured by the Rheo-Container-Process. Subsequent heat treatment raised the mechanical properties to maximum values of tensile strength of 432MPa, yield strength of 220MPa and an elongation of 13%. The RCP-Process was designed for the special requirements of this high reactive alloy. The paper will present extraordinary benefits in terms of properties and process simpleness for the semi-solid processing of Al-Li alloys.

Abstract:

The use of short process chains for the realization of complex and high performance components is a reasonable approach to achieve sustainable products and to reduce energy consumption. In the Collaborative Research Center SFB/TR TRR30 which is supported by the German Research Foundation DFG this approach is investigated applying thermo-mechanically forming processes. In this way, combining hot metal forming and heat treatment steps in a single process, tailored materials properties together with appropriate geometries are achieved [1, 2] . However, still additional machining operations, e. g. turning operations in case of shafts, are needed to achieve proper workpiece finish. Due to locally varying mechanical properties, undesired changings of the process conditions occur, leading to varying surface and subsurface properties, e.g. the residual stress state. It is well known that residual stresses have a major impact on the components properties during service [3]. In this paper, a survey is given about near surface residual stress states after exterior dry turning of differently heat treated cylindrical workpieces made of steel AISI 6150.

Abstract:

With a novel extrusion process which is investigated in the Collaborative Research Center Transregio 10 (SFB/TR10), it is possible to manufacture spatially curved aluminum profiles. This process is the base for an automated small and medium size batch production of light-weight frame structures. For the handling and machining of the spatially curved profiles, highly flexible machines and manufacturing equipment are needed. Today’s automated process chains do not reach a sufficient flexibility. This article introduces a new approach to handle and machine spatially curved profiles using a flexible gripping and clamping system. Firstly, the requirements concerning the process comprehensive gripping technology, which have to be fulfilled for a flexible small and medium batch production of light-weight frame structures, are specified. Subsequently, the function and design of a flexible gripping and clamping system are described. Furthermore, metrological processes to maintain a once reached condition of order during the entire process chain are depicted.

Abstract:

One major objective of the Collaborative Research Center SFB/TR10 is the flexible and competitive production of frame structures which meet the requirements of lightweight design. The development of composite extrusion by embedding continuous reinforcing elements, like e.g. steel wires, in profiles during the extrusion process illustrates one approach to fulfill these conditions. To assemble such composite profiles, joining processes and strategies have to be developed taking into account the special composite material characteristics. In addition, the flexible production of lightweight frame structures in small quantities generates more requirements on the joining technology. The feasibility of joining by forming has been carried out investigating experimentally both conventionally extruded and reinforced profiles. Therefore, joining profiles to lightweight frame structures by both expansion and compression has been examined. The necessary forming pressure for the joining by forming processes was applied to tubular workpieces by a medium (hydroforming) and by a magnetic field (electromagnetic compression). Joints have been manufactured by these two processes to transmit axial loads either by force- or form-fit.

Abstract:

Extruded aluminum profiles are essential for lightweight constructions in contemporary transport and automotive applications. The reinforcement of such aluminum-based profiles with high-strength materials offers a high potential for weight reduction and an improvement of functional and mechanical properties. In comparison to conventional composite extrusion using fiber or particle reinforced billets, the alternatively developed process for the embedding of endless reinforcing elements provides enormous advantages regarding extrusion forces, load-adapted reinforcement, and tool abrasion. In this extrusion process with conventional billets, modified tools with portholes are used to position reinforcing elements from outside the pressing tool and to embed them into the material flow during the pressing operation. This composite extrusion process is part of the research work started in 2003 and carried out within the scope of the Collaborative Research Center SFB/TR10. To increase the potential of composite extrusion with endless reinforcing elements, the manufacture of composite extrusion profiles with high-strength non-metallic alumina wires is planned. Due to the wires’ specific properties, e.g. high stiffness, their deflection behavior must be analyzed to guarantee a stable feeding-in process. In this paper the specific behavior of alumina reinforcing elements regarding the feeding-in process is analyzed by experimental investigations. The main influencing factors are determined and a process window is deduced.

Abstract:

The Collaborative Research Centre SFB/TR 39 PT-PIESA is developing mass production technologies and process chains for the fabrication of aluminium piezo composites, which can be used as raw material for "smart sheet metal" [1]. Microstructuring by forming is a challenging task concerning material flow, tool and process design [2]. In this study, a hybrid forming process combined of micro impact extrusion and shear displacement is presented and discussed. The formed microstructure, depicted in figure 1, consists of ten parallel primary cavities with cross sections of 0.3×0.3 mm² and four larger secondary cavities which are surrounding the primary cavities. High demands are made concerning precision and reproducibility of the cavities' geometry according to the function of the cavities, which is to serve as collets for sensitive piezo rods. The microstructure has to be formed with one stroke of the stamp. Micro backward impact extrusion is chosen for structuring the primary cavities since it allows accurate forming without aligning die plate and stamp due to a flat die plate. Shear displacement forming, which is the selected process for the secondary cavities, requires a structured and aligned die plate but the forming forces are significantly lower than forming the same geometry with an extrusion process which in turn increases the accuracy. The investigations are focused on the characterization of samples formed with the hybrid process in comparison to structures which are formed solely by impact extrusion. Geometric parameters, material flow and process parameters were evaluated to assess the hybrid process. First experiments show promising results, whereas higher degrees of deformation could be reached at lower forming forces. Exemplary, sections for both processes are depicted in figure 2.

Abstract:

Within traffic engineering, the importance of lightweight space frame structures continuously grows. The space frame design offers many advantages for light weight construction but also brings challenges for the production technology. For example, the important requests concerning product flexibility and reconfiguration can only be achieved with a high technical effort, if current machine technology is used. For this reason, the collaborative research center SFB/TR10 investigates the scientific fundamentals of a process chain for the product flexible and automated production of space frame structures. An important component in space frame structures are curved extrusion profiles. Within the investigated process chain, the extrusions must be machined mechanically in order to apply holes and to prepare the extrusion ends for the following welding operation.The machining is currently done by clamping the profile into a fixture and processing it within a machining center. This procedure has two disadvantages due to the complex geometry and the partially high length of the extrusion profiles: On the one hand, a complex fixture is needed for clamping the work piece [1]. On the other hand, a machining center with a large workspace and five machine axes is required [2]. Due to this, the product flexible machining with current technology is only possible with high technical and economical effort. For this reason, a new machine concept for the product flexible machining of three dimensionally curved extrusion profiles was developed at the University of Karlsruhe. In this paper, the function of the machine is explained and a prototype is presented. In addition, investigation results of the machining accuracy are shown and possibilities for improving the precision are discussed.

Abstract:

IntroductionResidency is a stressful phase associated with high prevalence of mental distress. Besides impaired personal health, mental distress in residents has an impact on the quality of patient care and produces economic costs. Therefore, there is demand for interventions that improve resident physicians’ mental health. The aim of the present study is to examine the effects of a mindfulness-based intervention that has been tailored to residents’ needs. Specifically, mindfulness has been supplemented by a focus on the concept of Muße.Methods and analysisThis study applies a randomised controlled multimethod design. Residents assigned to the intervention group will participate in an 8-week mindfulness course followed by a 4-month maintenance phase, whereas residents assigned to the control group will read text-based information about mindfulness on a weekly basis for the duration of 8 weeks. The intervention is focussed on a transfer of learnt techniques into the daily routine and is targeted to promote residents’ self-care as well as on building empathic relationships. Participants will be assessed before, directly after the intervention, after the maintenance phase as well as at follow-up 6 months after the intervention group completes the intervention. Assessments will consist of self-report measures, physiological data, qualitative interviews, third-party reports as well as implicit and projective measures and will focus on both psychopathology and salutogenesis. The primary outcome will be burnout. Data will be analysed using linear mixed modelling.Ethics and disseminationThe study was approved by the ethics committee of the Medical Center - University of Freiburg and is funded by the German Research Foundation as part of the interdisciplinary Collaborative Research Center ‘SFB Muße 1015’. The results of this study will be published in scientific journals and disseminated through the study’s website, and conferences.Trial registration numberDRKS00014015.

Abstract:

Abstract. Ocean observations are analysed in the framework of Collaborative Research Center 754 (SFB 754) "Climate-Biogeochemistry Interactions in the Tropical Ocean" to study (1) the structure of tropical oxygen minimum zones (OMZs), (2) the processes that contribute to the oxygen budget, and (3) long-term changes in the oxygen distribution. The OMZ of the eastern tropical North Atlantic (ETNA), located between the well-ventilated subtropical gyre and the equatorial oxygen maximum, is composed of a deep OMZ at about 400 m in depth with its core region centred at about 20° W, 10° N and a shallow OMZ at about 100 m in depth, with the lowest oxygen concentrations in proximity to the coastal upwelling region off Mauritania and Senegal. The oxygen budget of the deep OMZ is given by oxygen consumption mainly balanced by the oxygen supply due to meridional eddy fluxes (about 60%) and vertical mixing (about 20%, locally up to 30%). Advection by zonal jets is crucial for the establishment of the equatorial oxygen maximum. In the latitude range of the deep OMZ, it dominates the oxygen supply in the upper 300 to 400 m and generates the intermediate oxygen maximum between deep and shallow OMZs.

Abstract:

Abstract. Ocean observations carried out in the framework of the Collaborative Research Center 754 (SFB 754) "Climate-Biogeochemistry Interactions in the Tropical Ocean" are used to study (1) the structure of tropical oxygen minimum zones (OMZs), (2) the processes that contribute to the oxygen budget, and (3) long-term changes in the oxygen distribution. The OMZ of the eastern tropical North Atlantic (ETNA), located between the well-ventilated subtropical gyre and the equatorial oxygen maximum, is composed of a deep OMZ at about 400 m depth with its core region centred at about 20° W, 10° N and a shallow OMZ at about 100 m depth with lowest oxygen concentrations in proximity to the coastal upwelling region off Mauritania and Senegal. The oxygen budget of the deep OMZ is given by oxygen consumption mainly balanced by the oxygen supply due to meridional eddy fluxes (about 60%) and vertical mixing (about 20%, locally up to 30%). Advection by zonal jets is crucial for the establishment of the equatorial oxygen maximum. In the latitude range of the deep OMZ, it dominates the oxygen supply in the upper 300 to 400 m and generates the intermediate oxygen maximum between deep and shallow OMZs. Water mass ages from transient tracers indicate substantially older water masses in the core of the deep OMZ (about 120–180 years) compared to regions north and south of it. The deoxygenation of the ETNA OMZ during recent decades suggests a substantial imbalance in the oxygen budget: about 10% of the oxygen consumption during that period was not balanced by ventilation. Long-term oxygen observations show variability on interannual, decadal and multidecadal time scales that can partly be attributed to circulation changes. In comparison to the ETNA OMZ the eastern tropical South Pacific OMZ shows a similar structure including an equatorial oxygen maximum driven by zonal advection, but overall much lower oxygen concentrations approaching zero in extended regions. As the shape of the OMZs is set by ocean circulation, the widespread misrepresentation of the intermediate circulation in ocean circulation models substantially contributes to their oxygen bias, which might have significant impacts on predictions of future oxygen levels.

Abstract:

Abstract Background Infectious diseases (ID) consultation has been associated with improved outcomes for Staphylococcus aureus bacteremia (SAB) largely by providing guidance to follow widely accepted standards. However, ID consultation may be delayed due to numerous factors. ID pharmacists may be able to facilitate timely and optimal management of SAB in collaboration with ID providers and microbiology. The primary outcome of this study was to evaluate the impact of a pharmacist-driven collaborative initiative for SAB. Methods This was a single-center, quasi-experimental study of patients with SAB before (8/1/16–7/31/17) and after (8/1/18-7/31/19) implementation of pharmacist-driven collaborative initiative for SAB management. After direct notification of SAB and penicillin-binding protein assay results from microbiology personnel, the ID pharmacist promptly contacted the primary team to facilitate ID consultation and identified opportunities to optimize treatment or diagnosis prior to consult. Recommendations were also collaboratively discussed with the ID consult service. Included patients were ≥18 years old with SAB. Excluded patients were &lt; 18 years old, under palliative care or expired prior to S. aureus speciation, refused care against medical advice, pregnant, incarcerated, or had polymicrobial bacteremia. Results Ninety and 111 patients were included in the pre- and post-intervention cohort, respectively. Demographic data were similar between cohorts. Most SAB cases were community-acquired (72% vs 81%, p=0.137), complicated (83% vs 71%, p=0.059), and methicillin-susceptible (57% vs 65%, p=0.236). The most common sources were catheter (23%) and skin and soft tissue (30%) in pre- and post-intervention cohorts, respectively. Table 1 displays compliance with evidence-based SAB measures and clinical outcomes. Compliance with the SAB bundle was significantly higher in the post-intervention cohort (91% vs 50%, p&lt; 0.001). Table 1. Compliance with Evidence-Based Staphylococcus aureus Bacteremia Management Bundle Elements and Clinical Outcomes Conclusion Increased compliance with evidence-based SAB recommendations decreased SAB duration, time to targeted antibiotics, and infection-related hospital length of stay after implementation of a pharmacist-driven collaborative initiative for SAB.

Abstract:

The authors argue that the academic research centre can perform an invaluable function in coordinating the flow of information and knowledge between academic departments in a university and between the university and industry. To illustrate their argument, they offer a case analysis of the Center for Composite Materials at the University of Delaware and show that the Center not only opens up new sources of funding and collaborative research opportunities, but also enhances the skills of the students who collaborate in its programmes. They also describe new federal funding initiatives and point out that recent US government programmes are continuing to integrate research centres to solve real-world problems in close cooperation with industry.

Abstract:

At the end of this year, the Sonderforschungsbereich (Special Collaborative Programme) no. 132 on “Theoretical and Observational Stellar Astronomy” in Heidelberg will terminate after fifteen years. Although 15 years are only 2 1/2 per cent of the age of the University of Heidelberg, which is celebrating its 600 th anniversary this year, they are nevertheless a long and important time for astronomical research in Heidelberg. On the occasion of the termination of the Sonderforschungsbereich, we are now given the opportunity to present an essential part of its research, namely that on circumstellar matter at an international conference, and we are grateful to the International Astronomical Union that this could be realized, and that we can welcome here so many participants to this Symposium. As the Speaker of our Sonderforschungsbereich I would like to briefly introduce to you the general concept of the institution of an SFB and give an overview over its structure and research activities.

Abstract:

Purpose – Research data management (RDM) comprises all processes, which ensure that research data are well-organized, documented, stored, backed up, accessible, and reusable. RDM systems form the technical framework. The purpose of this paper is to present the design and implementation of a RDM system for an interdisciplinary, collaborative, long-term research project with focus on Soil-Vegetation-Atmosphere data. Design/methodology/approach – The presented RDM system is based on a three-tier (client-server) architecture. This includes a file-based data storage, a database-based metadata storage, and a self-designed user-friendly web-interface. The system is designed in cooperation with the local computing centre, where it is also hosted. A self-designed interoperable, project-specific metadata schema ensures the accurate documentation of all data. Findings – A RDM system has to be designed and implemented according to requirements of the project participants. General challenges and problems of RDM should be considered. Thus, a close cooperation with the scientists obtains the acceptance and usage of the system. Originality/value – This paper provides evidence that the implementation of a RDM system in the provided and maintained infrastructure of a computing centre offers many advantages. Consequently, the designed system is independent of the project funding. In addition, access and re-use of all involved project data is ensured. A transferability of the presented approach to another interdisciplinary research project was already successful. Furthermore, the designed metadata schema can be expanded according to changing project requirements.

Abstract:

This year marks the first decade of operations for the Gene Technology Access Centre (GTAC). The decade has seen a grassroots initiative by a small group of eminent research scientists and dedicated personnel from the University High School in Melbourne grow into a specialist education centre in cell and molecular biology that attracts over 6000 students and their teachers each year. GTAC has not only refocused student and teacher attention on the interdisciplinary nature of contemporary biology, but has also highlighted how a ?centre model for learning?, based upon collaboration and partnerships, can exist within ?the school system? and meet the needs of students and teachers from across Victoria and beyond.

Abstract:

Newly developed technologies and methods for the purpose of controlling uncertainty in technical systems must be proven and validated against reliable experimental studies. The availability of descriptive metadata is mandatory to enable long term usability and sharing of such experimental research data. This article introduces a concept for a software independent solution for managing data in collaborative research environments. The proposed approach leverages the advantages of capturing metadata in a uniform, modular data structure and providing software independent access to a centralized data repository as well as its contents by means of a web-application. The article presents a prototype implementation of the proposed approach and discusses its application on the demonstrator test rig of a collaborative research centre in the field of mechanical engineering.

Abstract:

Collaboration is a feature of all stages in the development and implementation of long-term research sites, and has traditionally occurred through the medium of face-to-face meetings. However, the recent development of Groupware software products permits collaboration and knowledge management over the Internet. A range of World Wide Web-based systems currently in operational use at the Pacific Forestry Centre are reviewed in terms of their capacity for knowledge management and their ability to facilitate collaboration. The manner in which the systems integrate World Wide Web and database technologies is described. We present a description of a prototype knowledge management system to facilitate dynamic, web-based collaborative construction of concept graphs and relationships. These will help researchers reach consensus on concepts and assumptions, make differences explicit to facilitate experimental resolution, and elicit knowledge from researchers external to the project.

Abstract:

This paper describes the value of collaboration from two perspectives. The first perspective highlights the benefit of teaching communication partners collaborative communication strategies to facilitate the interactions of people with traumatic brain injury (TBI). Collaborative strategies encompass the provision of collaborative intent, emotional and cognitive support, positive questioning styles and collaborative turn taking. Translating research outcomes into accessible resources is described with reference to the TBI Express website which has video demonstrations of conversation strategies for communication partners of people with TBI. The broader meaning of collaboration is also discussed, with particular focus on the advantages collaboration can provide in advancing rehabilitation outcomes for people with acquired brain injury, their families and social networks. Collaboration is described in terms of encompassing all relevant contributors to the development of research advances, including people with acquired brain injury, their families and social networks, stakeholders, clinicians, peak bodies, students and researchers. Two examples of large-scale research collaborations occurring within Australia are described, including the NHMRC Clinical Centre of Research Excellence in Aphasia Rehabilitation and the NHMRC Moving Ahead Centre for Research Excellence in Brain Recovery, also known as Moving Ahead.

Abstract:

To produce preforms for complex long flat parts with an unsteady mass distribution along the longitudinal axis rolling processes, like cross wedge rolling, can be used. Tools for cross wedge rolling processes can be constructed as roller or flat, both with wedges. In the collaborative research project SFB 489 “Process chain for the production of precision forged high performance parts” the subproject “Innovative machine and tool technology for precision forging” deals with the development of a flashless forging process for a two cylinder crankshaft with pin and flange. This process is developed by IPH – Institut für Integrierte Produktion Hannover. The first preform of the developed forging sequence is produced by a cross wedge rolling process on the basis of flat with wedges. To consider the mass distribution of the two cylinder crankshaft in the preform for a rolling process four mass concentrations for the crank arms and mass concentrations for pin and flange are needed.

Abstract:

This paper offers an overview of a recent practice-led doctoral enquiry which examined lighting techniques used by cinematographers and more widely amongst practitioners working with moving imagery. This research was completed in the Digital Cultures Research Centre at UWE Bristol and funded by the AHRC 3d3 Centre for Doctoral Training. The paper specifically reflects on three strands of enquiry which existed in dialogue with one another, showing how the mutual interaction and reinforcement between scholarly activity, collaborative film production and independent creative experimentation were fundamental to the approach and direction of the research. Amongst a wider contribution, this doctoral research can be seen as methodologically innovative, providing a more detailed first-hand investigation into lighting processes than is currently available by using autoethnographic methods to capture practical knowledge that is deployed in situ during moving image production. The paper discusses this novel use of autoethnography within practice-research and also explains how the resulting evidence was incorporated in the thesis through a layered approach to writing.
