title: Bounded natural frequencies of completely free rectangular plates

authors: Mochida, Yusuke

abstract: This paper presents dimensionless natural frequency parameters for completely free rectangular plates, calculated using the superposition method (SM) and the finite difference method (FDM). The convergence tests show that while the SM gives upper bound results the FDM gives lower bound results. The results obtained using the FDM appears to be the best lower bound results available to date. Together with the upper bound results from the SM, the maximum possible error in the first 12 non-zero natural frequency parameters for completely free rectangular plates of various aspects ratios ranging from 1:1 to 3:1 can be determined from the results presented here.

title: New development and trends in mathematics education at pre-school and primary level

authors: Jones, Graham

subjects: education

abstract: TSG 1 had a broad focus, calling for papers that examined contemporary developments in mathematics education at the preschool and primary level (approximately ages 0 through 12 years). This provided an exciting opportunity to explore issues across the early childhood and school sectors and the team quickly decided to integrate early childhood and school presenters, with sessions organized around common themes, rather than by sector. The range of nationalities of the presenters and the participants in this group also allowed the ideas to be considered as they applied in a number of different contexts. This report highlights the themes that were considered, describes the papers that were presented, and summarises some of the key ideas and issues that arose in the group’s discussions.
