Challenges for turbomachinery CFD in the 21st century

This lecture aims to identify a range of problems in turbomachinery which deserve attention. There is a discussion of what current levels of CFD can offer towards solving these problems. Finally, fruitful areas of future CFD research are described and current progress in these areas is summarised.

AI in the 21st century - With historical reflections

The discipline of Artificial Intelligence (AI) was born in the summer of 1956 at Dartmouth College in Hanover, New Hampshire. Half of a century has passed, and AI has turned into an important field whose influence on our daily lives can hardly be overestimated. The original view of intelligence as a computer program - a set of algorithms to process symbols - has led to many useful applications now found in internet search engines, voice recognition software, cars, home appliances, and consumer electronics, but it has not yet contributed significantly to our understanding of natural forms of intelligence. Since the 1980s, AI has expanded into a broader study of the interaction between the body, brain, and environment, and how intelligence emerges from such interaction. This advent of embodiment has provided an entirely new way of thinking that goes well beyond artificial intelligence proper, to include the study of intelligent action in agents other than organisms or robots. For example, it supplies powerful metaphors for viewing corporations, groups of agents, and networked embedded devices as intelligent and adaptive systems acting in highly uncertain and unpredictable environments. In addition to giving us a novel outlook on information technology in general, this broader view of AI also offers unexpected perspectives into how to think about ourselves and the world around us. In this chapter, we briefly review the turbulent history of AI research, point to some of its current trends, and to challenges that the AI of the 21st century will have to face. © Springer-Verlag Berlin Heidelberg 2007.

Creative environments for art, craft & design teaching in the 21st century

This booklet has been designed for student teachers in particular and those in their early years as teachers of art, craft and design. It is suitable however for all teachers of art and design, and will be useful when considering the 2007 review of the Art and Design programme of study (POS) with its focus on creativity and ideas developments. The contents are intended as prompts or guides and ideas for initiating individual responses to themes or projects and a "way in" for the teacher when guiding pupils. It explains in detail how one might inspire all groups with appropriate and varied resources.

Projecting marine fish production and catch potential in Bangladesh in the 21st century under long-term environmental change and management scenarios

The fisheries sector is crucial to the Bangladeshi economy and wellbeing, accounting for 4.4% of national Gross Domestic Product (GDP) and 22.8% of agriculture sector production, and supplying ca.60% of the national animal protein intake. Fish is vital to the 16 million Bangladeshis living near the coast, a number that has doubled since the 1980s. Here we develop and apply tools to project the long term productive capacity of Bangladesh marine fisheries under climate and fisheries management scenarios, based on downscaling a global climate model, using associated river flow and nutrient loading estimates, projecting high resolution changes in physical and biochemical ocean properties, and eventually projecting fish production and catch potential under different fishing mortality targets. We place particular interest on Hilsa shad (Tenualosa ilisha), which accounts for ca.11% of total catches, and Bombay duck (Harpadon nehereus), a low price fish that is the second highest catch in Bangladesh and is highly consumed by low income communities. It is concluded that the impacts of climate change, under greenhouse emissions scenario A1B, are likely to reduce the potential fish production in the Bangladesh Exclusive Economic Zone (EEZ) by less than 10%. However, these impacts are larger for the two target species. Under sustainable management practices we expect Hilsa shad catches to show a minor decline in potential catch by 2030 but a significant (25%) decline by 2060. However, if overexploitation is allowed catches are projected to fall much further, by almost 95% by 2060, compared to the Business as Usual scenario for the start of the 21st century. For Bombay duck, potential catches by 2060 under sustainable scenarios will produce a decline of less than 20% compared to current catches. The results demonstrate that management can mitigate or exacerbate the effects of climate change on ecosystem productivity.

The role of the Professional Engineer in the 21st century

In light of the current world economic and environmental crisis due in part to
unsustainable development and poor financial planning, 21st Century engineers are faced with unprecedented challenges of developing a sustainable world in balance with the forces of nature to combat global environmental, social and economic crises. The European Union, the United States of America and a number of other countries have identified that smart solutions and highly skilled professionals are needed to survive climate change and create long-term prosperity. In this paper the evolution of the changing career of the engineer will be presented. The policy background to the current system of engineering education at bachelor’s and graduate level in Ireland will be introduced and perceptions of engineering as a profession by society in general, and by
school leavers selecting third level courses will be discussed. The role of the engineer as a specialist, expert or generalist will also be studied in terms of the changing demands and needs of society. Finally the responsibility of universities, through broad-based multidisciplinary teaching and training, to prepare the next crop of engineers will be examined.
