Relating Research and Teaching: comparing experiences and beliefs
No full textThe relationship between research and teaching has possible benefits and inherent tensions. It is a recurrent topic of discussion by faculty including engineering educators. Exploring a potentially beneficial relationship and is of interest and possible value to engineering faculty, our students, and our stakeholders. Institutions and departments have developed a range of approaches including research-led, research informed, or just plain scholarly. This paper examines the relationship between research and teaching in the undergraduate curriculum. It compares and contrasts evidence of the beliefs and experiences of the engineering faculty and the engineering student. It presents and analyses the result of surveys which gathered qualitative and qualitative data to explore the inter-relationship of research and teaching; in the curriculum; and as it is delivered and experienced in the lab, seminar room and lecture hall. This research builds on existing work developed in a preliminary study which examined ways in which synergies between research and teaching could be achieved, particularly in the ‘hard/applied’ areas of the curriculum. It analyses data from the ‘research-intensive’ and the ‘teaching-intensive’ perspective
Education for Cataloging in Spanish Universities: A Descriptive and Critical Study
No full textObjective: This is a critical descriptive study of the situation of cataloging as an academic discipline within Library and Information Science studies in Spain. Material and methods: The descriptive analysis of the sectional contents of the general and specific guidelines of the degrees of Diplomado (three-year degree) and Licenciado (fiveyear degree) in LIS and the curricular programs of the Spanish university schools or departments. Variables analyzed: The denomination and content descriptors of the course offerings and credit hours. The test-retest method was used, with a qualitative processing of data. Results: General data is given about the studies in LIS: their introduction, the universities that offer them, and the degrees awarded. Cataloging is considered an obligatory core subject matter, and is represented by several courses that present important differences insofar as their denominations, their credits, and their character from one curricular program to the next. The average credit requisite for obligatory courses in cataloging in Spain is 14 (1 credit = 10 class hours), and 19.7 if electives are also considered. At present, this discipline is undergoing a reform that will produce important changes as a result of the adaptation of university studies to the common framework of the European Union
Introduction to Energy-Efficient Train Operation
No full textRailway, as one of the most energy-efficient transport, plays an essential role in improving the world’s energy and environmental sustainability. Statistics about rail share of transport activities and the corresponding energy consumption will demonstrate the energy efficiency of railway and indicate the potential of developing railway transport. Therefore, this chapter will provide an overview of the railway's energy consumption and traffic volume shares. Statistics presented in this chapter show that railway energy consumption decreased in these decades while its transport volume kept stable, and the traffic volume share of the railway is extremely large in urban transport. To achieve the goal of carbon neutralization, the European Union and many countries have conducted research projects on railway energy conservation. The technologies developed in these projects include energy-efficient train driving, integrated timetabling, using regenerative braking energy, etc. A summary of these technologies is also given, along with their potential energy savings, which range from 1 to 25%. This book will analyse and illustrate the whole systems processes of train operation with optimisation solutions. The structure of the following chapters will be presented at the end.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Plannin
A Chinese lecturer in an English university: an unfinished journey
No full textThis chapter portraits a learning journey of an academic. The narrative chapter points a way forward to new modes of inter-cultural understanding of learners. The author of this chapter invites the readers to become fellow travellers to gain from his unique learning journeys an understanding of what is common to all learning. The chapter indicates that learning is often transformative, indeterminate and unfinished. The author invites readers to consider following questions: what do they tell us about learning itself? About what it means to be a learner in the first quarter of the 21st Century? What do we learn about the experience of learning

The Use of LiDAR in Multi-Scale Forestry Applications
No full textForest ecosystems are a significant faction of the Earth’s landscape, and accurate estimates of forest structures are important for understanding and predicting how forest ecosystems respond to climate change and human activities. Light detection and ranging (LiDAR) technology, an active remote sensing technology, can penetrate the forest canopy and greatly improve the efficiency and accuracy of mapping forest structures, compared to traditional passive optical remote sensing and radar technologies. However, currently, LiDAR has two major weaknesses, the lack of spectral information and the limited spatial coverage. These weaknesses have limited its accuracy in certain forestry applications (e.g., vegetation mapping) and its application in large-scale forest structure mapping. The aim of research described in this dissertation is to develop data fusion algorithms to address these limitations. In this dissertation, the effectiveness of LiDAR in estimating forest structures and therefore monitoring forest dynamics is first compared with aerial imagery by detecting forest fuel treatment activities at the local scale. Then, a vegetation mapping algorithm is developed based on the fusion of LiDAR data and aerial imagery. This algorithm can automatically determine the optimized number of vegetation units in a forest and take both the vegetation species and vegetation structure characteristics into account in classifying the vegetation types. To extend the use of LiDAR in mapping forest structures in areas without LiDAR coverage, a data fusion algorithm is proposed to map fine-resolution tree height from airborne LiDAR, spaceborne LiDAR, optical imagery and radar data in regional scale. Finally, this dissertation further investigates the methodology to integrate spaceborne LiDAR, optical imagery, radar data and climate surfaces for the purpose of mapping national- to global-scale forest aboveground biomass. The proposed data fusion algorithms and the generated regional to global forest structure parameters will have important applications in ecological and hydrologic studies and forest management

[[alternative]]Finding a Balance Between Accuracy and Readability in Translation: A Case Study of Su Chi's "On the Brink"
No full text[[abstract]]This paper discusses free and literal translation, how the debate between proponents of the two philosophies developed in China, and how my study of both types of translation has influenced my work as a translator. I discuss factors that influence Chinese to English translation and how translators can strike a balance between accuracy and readability in their translations. Finally, I explain my personal approach to translation and why I use this approach. I use Su Chi’s book On the Brink as an example.
