S1NN GmbH & Co. KG (Automobile Connectivity Module 1.1)
The results of this report show how when diagnostics were run on the Connectivity Module 1.1, the problems discovered such as potential short-circuiting, 90-degree copper tracing angles, and components overheating/tombstoning were addressed. By using the method of “DMAIC,” which stands for Design, Measure, Analyze, Implement, Control, successful corrections were made. In the first design of the Printed Circuit Board (PCB), 1454 critical issues were found. With the newly designed PCB’s modifications being implemented, only 12 critical issues remained, which were later addressed and corrected. The results from this report are a functional Automobile Connectivity Module 1.1
One-loop fermion determinant with explicit chiral symmetry breaking
We use a proper-time regularization to define the one-loop fermion
determinant for the case in which explicit chiral symmetry breaking takes
place. We show how to obtain the polynomial by which the standard definition of
lndetD needs to be modified in order to arrive at the fermion determinant whose
transformation properties are consistent with the general symmetry requirements
of the basic Lagrangian. As an example it is shown how the fundamental
symmetries and the explicit chiral symmetry breaking pattern associated with
the ENJL model are preserved in a consistent way.Comment: 7 pages, plain LaTe
Show me the data: the pilot UK Research Data Registry
The UK Research Data (Metadata) Registry pilot project is implementing a prototype registry for the UK's research data assets, enabling the holdings of subject-based data centres and institutional data repositories alike to be searched from a single location. The purpose of the prototype is to prove the concept of the registry and uncover challenges that will need to be addressed if and when the registry is developed into a sustainable service. The prototype is being tested using metadata records harvested from nine UK data centres and the data repositories of nine UK universities
Scaling-up valued ecosystem components for use in watershed cumulative effects assessment
The accumulating impacts from human development are threatening water quality and availability in the watersheds of Western Canada. While environmental impact assessment (EIA) is tasked with identifying such cumulative impacts, the practice is limited to individual projects, is not widely applied, overlooks activities occurring on the landscape, and fails to capture the effects of multiple projects over time. Limitations of the project-by-project approach are spurring the emergence of a regional framework for assessing aquatic cumulative effects within watershed boundaries. Watershed-based cumulative effects assessment (WCEA) will need a standard set of ecosystem components and indicators for assessment across the watershed, but it is not clear how such valued ecosystem components (VECs) and related measurable parameters should be identified. This study examined how aquatic VECs and indicators were used within project-based EIA in the South Saskatchewan River watershed and considered whether they could be scaled up for use in WCEA. A semi-quantitative analysis compared a hierarchy of assessment components and measurable parameters identified in the environmental impact statements of 28 federal screening, 5 federal comprehensive and 2 provincial environmental assessments from the South Saskatchewan River watershed, and examined factors affecting aquatic VEC selection. While provincial assessments were available online or at a central archive, federal assessments were difficult to access. Results showed that regulatory compliance was the dominant factor influencing VEC selection, followed by the preferences of government agencies with different mandates, and that provincial licensing arrangements interfered with VEC selection. The frequency of VECs and indicators used for aquatic assessment within EIA does not reflect the aquatic cumulative effect assessment (CEA) priorities for the watershed. The effective selection of VECs and indicators for aquatic cumulative effects assessment in practice requires both the implementation of WCEA and updating of guidelines for project-based EIA
Comparing teacher roles in Denmark and England
This article reports the findings of a comparative study of teaching in Denmark and England; its broader aim is to help develop an approach for comparing pedagogy. Lesson observations and interviews identified the range of goals towards which teachers in each country worked and the actions these prompted. These were clustered using the lens of Bernstein’s pedagogic discourse (1990; 1996) to construct teacher roles which provided a view of pedagogy. Through this approach we have begun to identify variations in pedagogy across two countries. All teachers in this study adopted a variety of roles; of significance was the ease with which competent English teachers moved between roles. The English teachers observed adopted roles consistent with a wider techno-rationalist discourse. There was a greater subject emphasis by Danish teachers whose work was set predominantly within a democratic humanist discourse, whilst the English teachers placed a greater emphasis on applied skills
The Minimum Mandatory Metadata Sets for the KIM Project and RAIDmap
A Minimum Mandatory Metadata Set (M3S) was devised for the KIM (Knowledge and Information Management Through Life) Project to address two challenges. The first was to ensure the project’s documents were sufficiently self-documented to allow them to be preserved in the long term. The second was to trial the M3S and supporting templates and tools as a possible approach that might be used by the aerospace, defence and construction industries. A different M3S was devised along similar principles by a later project called REDm-MED (Research Data Management for Mechanical Engineering Departments). The aim this time was to help specify a tool for documenting research data records and the associations between them, in support of both preservation and discovery. In both cases the emphasis was on collecting a minimal set of metadata at the time of object creation, on the understanding that later processes would be able to expand the set into a full metadata record
