title: Using 2D and 3D landmarks to solve the correspondence problem in cognitive robot mapping

authors: Jefferies, Margaret E.

subjects: computer science

abstract: We present an approach which uses 2D and 3D landmarks for solving the correspondence problem in Simultaneous Localisation and Mapping (SLAM) in cognitive robot mapping. The nodes in the topological map are a representation for each local space the robot visits. The 2D approach is feature based – a neural network algorithm is used to learn a landmark signature from a set of features extracted from each local space representation. Newly encountered local spaces are classified by the neural network as to how well they match the signatures of the nodes in the topological network. The 3D landmarks are computed from camera views of the local space. Using multiple 2D views, identified landmarks are projected, with their correct location and orientation into 3D world space by scene reconstruction. As the robot moves around the local space, extracted landmarks are integrated into the ASR s scene representation which comprises the 3D landmarks. The landmarks for an ASR scene are compared against the landmark scenes for previously constructed ASRs to determine when the robot is revisiting a place it has been to before.

title: No differences in neuromuscular power and range of motion, but greater muscle soreness in young vs masters athletes following a 12km run

authors: Driller, Matthew W.

subjects: DOMS

abstract: The purpose of the study was to assess lower-body neuromuscular power and range of motion in young and masters recreational runners before and after a 12km run. Methods: In a straight-forward parallel group trial, participants performed a number of tests pre and post a 12km run. Participants included 36 recreational runners (mean ± SD; 12km run time: 67 ± 18 mins) and were matched on running ability and divided into two groups; young (< 35 y, n=18) and masters (> 40 y, n=18). Pre and post measures included body mass, vertical jump height (m), peak jump velocity (m.s-1), sit and reach test (cm), mean 6s cycling power (W), peak cycling power (W) and perceived muscle soreness. Results: There were no significant differences (p > 0.05) between groups for any of the measured variables pre to post run, except for muscle soreness (p < 0.01), where the young group experienced significantly higher levels of soreness, associated with a large effect size between groups (-1.03 ±0.6). Conclusions: There were no differences in neuromuscular power and range of motion between young and masters athletes following a 12km run. This was possibly due to the exercise not being a demanding enough stimulus to cause fatigue in the measures used. However, masters athletes perceived lower levels of muscle soreness pre to post run, possibly due to decreased pain perceptions with aging. ￼Keywords DOMS, Aging, Running, Neuromuscular

title: Older adult education in a New Zealand university: Developments and issues

authors: Findsen, Brian

abstract: This article explores a case study of educational provision for older adults in the context of continuing education in one of New Zealand’s universities. It explains how developments in older adult education at the University of Waikato have reflected historical and cultural trends related to the wider field of adult and community education (ACE) inside a higher education setting. It discusses issues of tertiary education policy and funding, what constitutes curriculum and provision for older adults and how university-community partnerships have shaped opportunities for both indigenous Māori and Pakeha (European) seniors. Government removal of funding to all universities in New Zealand for ACE at the end of 2012 ended formal provision but older adult education groups, formerly supported by the Centre for Continuing Education in the University of Waikato, have assumed a more proactive stance in planning and implementing their own programmes.
