title: Ultimate moment capacity of bolted joint for cold-formed aluminium back-to-back channel sections

authors: Hasan, Zahid

subjects: Bolted joints

abstract: Cold-formed aluminium (CFA) channel sections are gaining popularity in structural applications as a lightweight and corrosion-resistant alternative to carbon steel, especially in coastal and aggressive environments. However, their effective use depends critically on the performance of their connections. This research investigates the structural behaviour of bolted moment connections in back-to-back CFA channel sections. Key factors such as web buckling, shear lag, and bending shear interaction were identified as influencing the ultimate moment capacity of these joints. An extensive numerical study of 1008 validated finite element (FE) models was conducted using ABAQUS. Moreover, validation was carried out based on experimental tests available in the literature. The Direct Strength Method (DSM) showed noticeable deviations from FE results in several cases, highlighting the limitations of DSM when applied to CFA sections. A parametric analysis was performed to examine the influence of cross-sectional size, thickness, web holes, and aluminium alloy grade and temper. Based on these findings, a new predictive equation is proposed for the reduced moment capacity of CFA back-to-back channel sections. The equation was rigorously assessed for reliability and accuracy, and it provides a practical tool for engineers designing CFA portal frame connections.

title: Challenges in cross-cultural/multilingual music information seeking

authors: Lee, Jin Ha

subjects: user behaviors

abstract: Understanding and meeting the needs of a broad range of music users across different cultures and languages are central in designing a global music digital library. This exploratory study examines cross-cultural/multilingual music information seeking behaviors and reveals
some important characteristics of these behaviors by analyzing 107 authentic music information queries from a Korean knowledge search portal Naver (knowledge) iN and 150 queries from Google Answers website. We conclude that new sets of access points must be developed to accommodate music queries that cross cultural or language boundaries.

title: E tama Hikairo

authors: Maxwell, Te Kahautu

subjects: Oriori

abstract: He oriori tēnei mō Hikairo, te mokopuna tuatahi a Kīngi Tūheitia. He oriori tēnei e whakanui ana i a Hikairo, tōna whakapapa, tōna tūranga i te ao Māori me te ao Kīngitanga. He mokopuna Ringatū anō a Hikairo, nā Kīngi Tūheitia i tuku mai a Hikairo kia tūātia e Te Hāhi Ringatū ki te Poukai o Wāhi Pā i te tuawaru o Whiringa-ā-Nuku 2014. Ka whakaaturia tōna whakapono Hāhi Ringatū ki roto i te oriori nei e kupu whakaaritia ana. I tohua hoki e Kīngi Tūheitia a Te Kāhautu hai pou whakaruruhau1 mō Hikairo koinei ia i titoa ai tēnei oriori mō tana tamaiti mokopuna, mō Hikairo. He aroha nui nō te matua mō wai oti, mō Hikairo.

I titoa tēnei oriori hai waiatatanga mā te kapa haka o Ōpōtiki Mai Tawhiti. I waiatatia e Ōpōtiki Mai Tawhiti tēnei ki Te Matatini i tū ki Ōtautahi te tau rua mano tekau mā rima. He huarahi anō tēnei mā Te Kāhautu ki te whakamānawa i tana mokopuna i a Hikairo, nara nā te kapa haka a Te Kāhautu i waiata, i whakanui a Hikairo ki te maraenui o te iwi Māori, ko Te Matatini. Ana i tuatahi a Hikairo i te wehenga o Te Waiata Tira. “E Tama Hikairo, haere mai rā.”
