title: Capturing Context in Collaborative Profiles

authors: Jung, Doris

subjects: computer science

abstract: In various application areas for alerting systems, the context and knowledge of several parties affect profile definition and filtering. For example, in healthcare nurses, doctors and patient influence the treatment process. Thus, profiles for alerting systems have to be generated by the explicit collaboration of several parties who may not know each other directly. 
We propose the new concept of collaborative profiles to capture these different conditions and contexts. These profiles exploit each single party’s expert-knowledge for defining the context under which (health-related) alerting is required. Challenges include the definition and refinement of profiles as well as conflict detection in context definitions.

title: Effect of spacers on axial capacity of cold-formed steel back-to-back gapped channel sections

authors: Divi, Seshagiri Rao

abstract: The use of cold-formed steel (CFS) gapped back-to-back channel sections is becoming popular, especially in New Zealand and South-East Asia. Introducing a gap between the back-to-back channels enhances resistance to lateral-torsional buckling. Previous research has investigated gapped built-up channel sections with spacers but hasn't determined the optimal number of spacers relative to length. Also, little attention has been given to how transverse spacing affects the axial capacity of these sections. This study fills those gaps by developing and validating a non-linear elastoplastic finite element (FE) model against experimental data. A parametric study of 1000 FE models examine the effects of column length, CFS section thickness, materials properties, and spacer spacing, on the axial capacity of gapped built-up columns. Key findings include: (1) Up to a column length of 4000 mm, three equally spaced spacers optimize compressive strength in gapped sections. (2) Optimal transverse spacing aligns with the channel web depth, offering no significant strength increase beyond 1.5 times the web depth. (3) Gapped sections show a substantial average increase (424%) in compressive strength over single-channel configurations, and a moderate improvement (125%) compared to non-gapped built-up sections. (4) FEA results closely match the predictions of AS/NZS4600:2018, differing by only 5% in compressive strength.

title: Te Raupatu o Tauranga Moana = The confiscation of Tauranga lands. [Volume 1]

authors: Stokes, Evelyn

subjects: Tauranga lands

abstract: A report providing a historical and geographical overview on the confiscation of Tauranga lands. In two volumes, volume one comprises a narrative of the events described as the raupatu, the confiscation of lands in the Tauranga Moana tribal area under the New Zealand Settlements Act 1863.  Volume two is a collection of documents, edited and annotated which were compiled in support of the report. These documents include personal accounts, tribal history, land purchases, lands returned and crown transactions.
