A Proposed Method to Identify Requirements Significant to Mass Reduction

Reducing the mass of engineering products holds the potential for significant benefits by reducing material costs, environmental impact, transportation costs, and in the case of vehicles, reducing fuel consumption. While there are many approaches for reducing mass, analyzing requirements has the greatest potential since requirements definition is the earliest phase of product development, where the most design freedom exists. This thesis proposes a requirement analysis method that identifies requirements that impact significant amounts of mass. The research hypothesis is: Engineering requirements can be represented and processed in a systematic manner and linked to physical components and systems, thus enabling mass reduction in reverse engineering and product redesign. The approach proposed in this research follows. Engineering requirements are linked to mass through the creation of a standard requirement statement using pre-processing rules and syntax rules. These rules and guidelines are applicable to authoring new requirements and analyzing existing requirements documentation. The processed engineering requirements are linked to physical components and assemblies based on how the requirements affect the components. These relationships are captured in Design Structure Matrices (DSMs) and Domain Mapping Matrices (DMMs). These DMMs and DSMs are used to attain the amount of mass each requirement affects and the level of coupling of each requirement. Further, representations of the requirements, components, and associated relationships are represented using two software tools. First, a systems engineering tool is used to model the system. Second, this model is exported to a traditional spreadsheet application to perform basic mathematical and data filtering functions. Finally, the method is demonstrated on three subsystems of Family of Medium Tactical Vehicle (FMTV) truck

Timor leste collaborative project: a short report

This report discusses findings from a small-scale scoping study, which is part of a larger curriculum project—a collaborative venture between staff from the Universidade Nacional Timor Lorosa'e (UNTL) and a New Zealand university. The aim of the wider project is to develop a context-sensitive English language curriculum for students at UNTL who are undergoing pre-service training to be teachers of English as a foreign language in local secondary schools. (Details of the institutional and linguistic context are provided in the appendix.) According to Norton (2000), investment by learners is a key factor in the successful implementation of a new curriculum: "if learners invest in a second language, they do so with the understanding that they will acquire a wider range of symbolic and material resources, which will increase their value in the social world" (Norton, 2000, pp. 165-166). Thus, when designing the curriculum, it is important to ensure that the students will not only understand how to use the specific learning tasks but that it also expands their repertoire of skills and knowledge for application in their subsequent professional and social lives. The report begins by outlining the history and objectives of the project before explaining the specific research questions posed for the scoping study. The means of collecting data will be outlined and examples of the participants' attitudes will be presented based on open-ended questionnaire responses. These findings will be discussed in terms of how they might lead to the design of a curriculum which is internationally-framed and context-sensitive in terms both of its content and implementation. The report will conclude with the further steps that are being taken to move the project to its next phase

Teaching and learning an ethnic minority language at university level: the case of Dusun in Brunei

This article investigates the teaching and learning of an ethnic minority language at tertiary level as a strategy for language maintenance and revitalisation. We offer a case study of the Dusun language, which is taught as a breadth/elective course at the Language Centre in Universiti Brunei Darussalam. Although the initial purpose of introducing ethnic language courses was to encourage students to be familiar with the practices and the cultural knowledge associated with the community of users, their role in language maintenance is also worthy of investigation. The research methods include classroom observations, a questionnaire survey and analysis of examination results. The observation and the survey assist in the understanding of students’ reactions to the curriculum. We find that offering Dusun as a credit-bearing language module (course) has generated interest among both students and the wider Brunei community. Those from Dusun family backgrounds taking the module are a minority: most students have no family connections with Dusun. The implementation of the curriculum remains problematic, and there are issues resulting from the need to meet the formal requirements and academic expectations of the university administration in terms of coursework and examinations. The absence of dictionaries, grammars and other pedagogical materials means that Dusun language teachers are obliged to develop their own materials and resources. We argue that offering Borneo minority indigenous languages at tertiary level may not in itself maintain or revive the language in question, but is one strategy, along with several others, which may help towards maintenance and revitalisation

Induction of Colonic Aberrant Crypts in Mice by Feeding Apparent N-Nitroso Compounds Derived From Hot Dogs

Nitrite-preserved meats (e.g., hot dogs) may help cause colon cancer because they contain N-nitroso compounds. We tested whether purified hot-dog-derived total apparent N-nitroso compounds (ANC) could induce colonic aberrant crypts, which are putative precursors of colon cancer. We purified ANC precursors in hot dogs and nitrosated them to produce ANC. In preliminary tests, CF1 mice received 1 or 3 i.p. injections of 5mg azoxymethane (AOM)/kg. In Experiments 1 and 2, female A/J mice received ANC in diet. In Experiment 1, ANC dose initially dropped sharply because the ANC precursors had mostly decomposed but, later in Experiment 1 and throughout Experiment 2, ANC remained at 85 nmol/g diet. Mice were killed after 8 (AOM tests) or 17–34 (ANC tests) wk.Median numbers of aberrant crypts in the distal 2 cm of the colon for 1 and 3 AOMinjections, CF1 controls, ANC (Experiment 1), ANC (Experiment 2),and untreated A/J mice were 31, 74, 12, 20, 12, and 5–6, with P < 0.01 for both ANC tests. Experiment 2 showed somewhat increased numbers of colonic mucin-depleted foci in the ANC-treated group. We conclude that hot-dog-derived ANC induced significant numbers of aberrant crypts in the mouse colon

Micro-generation in conflict: The conditions necessary to power economic development in rural Afghanistan

Access to reliable electricity eludes many poor rural Afghan communities despite plentiful renewable resources. Micro-generation seems particularly well suited to Afghanistan’s mountainous, decentralised society but even with substantial investment since 2001 it has not lived up to expectations. Recognising the causes are likely to dwell in the human (rather than technical) domain, this study takes a qualitative, soft systems approach to deriving and validating the necessary conditions that might improve the success rate of micro-generation projects in enabling sustainable economic development. It acknowledges the governance limitations inherent in fragile states and the significance of the community as the most stable element of society, putting the latter at the centre of its thinking. Those conditions identified as critical are summarised as: a holistic approach that sees micro-generation as a component of broader economic development; an environment safe enough for project build and operation, and for the markets necessary for wealth creation; and external support to build community capacity to fund and maintain schemes through-life. These conditions are likely to have relevance for other fragile states; the next step is to develop them in the field before deployment as part of a comprehensive approach to poverty alleviation in Afghanistan and similar states

Religion, community service, and identity in American youth

The role of religion in identity development has, for many years, been a relatively neglected topic In psychology. To demonstrate the importance of religion to the formation of identity, this paper presents evidence connecting community service and religiousness in American youth. Data are reviewed that show youth are heavily involved in volunteer service; many youth view religion as important and those who do so are more likely to do service than youth who do not believe that religion Is important in their lives; involvement in church-sponsored service makes it more likely that youth will adopt the religious rationale in which service is couched; and youth who do church-sponsored service are neither service nerds nor single-Issue tunnel-visioned adolescents. These data from nationally representative samples strengthen the case that the many contemporary youth who take religion seriously are vibrantly engaged in their schooling, in the betterment of communities, and the development of identities which presage healthy lives

What We Know About Engendering Civic Identity

Taking the position that there is a developmental process in the formation of citizenship, the authors reviewed studies that reported a link between youth\u27s participation in organized activities and civic behaviors 15 or more years later in adulthood. Data uniformly showed that students who participated in high school government or community service projects, meant in the broad sense, are more likely to vote and to join community organizations than are adults who were nonparticipants during high school. Results support the authors\u27 view that participation during the youth era can be seminal in the construction of civic identity that includes a sense of agency and social responsibility in sustaining the community\u27s well-being
