The effectiveness of project-based learning on net-generation aerospace engineering students

This paper presents an analysis of project based learning for today’s engineering students, of the ‘net-generation’. The learning attributes of the so-called ‘net-generation’, being characterised by their exposed to computer technology throughout their childhood development, generate specific challenges to educators, as traditional education techniques are less effective. Independent learning and active collaborative learning are critical components of the project based learning technique, which may be an effective educational tool for academics to exploit. These approaches match the preferred learning style of ‘netgeneration’ students who exhibit strong preference for independent learning, group work and the use information and communication technologies. This investigation is supported by a case study, of a project conducted by final year students, in the School of Mechanical Engineering, at The University of Adelaide.Dorothy L.

DEVELOPMENT OF STATIC MIXERS FOR MISCIBLE FLUIDS IN LAMINAR FLOW WITH THE USE OF COMPUTATIONAL FLUID DYNAMICS (CFD)

Static mixers with improved performance were developed from CFD simulations in a stepwise approach. The relevant geometric features of simple mixer designs and the corresponding mixing mechanisms-laminar shear, elongational flow, and distributive mixing-were identified first. This information was used to formulate guidelines for the development of new geometries. The solid elements of the static mixer should: (a) provide restrictions to the flow; (b) deflect the flow; (c) be sequentially rotated around the flow direction to provide symmetry; (d) extend from the center of the pipe to the vicinity of the walls to avoid short-circuiting; and (e) distribute and remix the flow. Based on these guidelines, two improved mixer designs were developed: the DS A-I mixer has a good mixing efficiency and an acceptable pressure drop; the Fins 35 degrees mixer is more efficient and compact, but requires a larger pressure drop. Their performance indicates that their use is possible on industrial applications

Populasi Buaya Senyulong (Tomistoma Schlegelii) di Taman Nasional Tanjung Puting Kabupaten Kotawaringan Barat Kalimantan Tengah

Indonesia known as center of Senyulong Crocodile (Tomistoma schlegelii) habitat in Southeast Asia, beside Sarawak and Peninsula Malaysia, Thailand and Brunei Darussalam. In the country, the crocodile can be found in East Sumatra, Kalimantan, and West Java. This research aims to determine the population and structure of Senyulong Crocodile (Tomistoma schlegelii) in Tanjung Puting National Park in West Kotawaringin District, Central Kalimantan. As the results, as many as 56 individuals of Senyulong Crocodile were found in the Camp Leakey Area (Sekonyer Kanan River) to Muara (Muara Ali) within the park, including 8 adult individuals, 15 individual children, and 33 individual infants. Opportunities for the appearance of one individual in the census (p) are 0,58 with a standard deviation (S) of 3.90. Population density (N) estimated about 16.09 individuals. The average observed individual from each observation (x?) was 9.33 individuals
