title: 3D Shape Reconstruction from Multiple Range Image Views

authors: Ganapathi Annadurai, Kartick

subjects: shape reconstruction

abstract: Shape reconstruction of different three dimensional objects using multiple range images has evolved recently within the recent past. In this research shape reconstruction of a three dimensional object using multiple range image views is investigated.
Range images were captured using the Waikato Range Imager. This range images camera is novel in that it uses heterodyne imaging and is capable of acquiring range images with precision less than a millimeter simultaneously over a full field. Multiple views of small objects were taken and the FastRBF was explored as a mean of registration and surface rendering. For comparison to the real range data, simulated range data under noise free condition were also generated and reconstructed with the FastRBF tool box.
The registration and reconstruction of simple object was performed using different views with the FastRBF toolbox. Analysis of the registration process showed that the translation error produced due to distortion during registration of different views hinders the process of reconstructing a complete surface. While analyzing the shape reconstruction using the FastRBF tool it is also determined that a small change in accuracy values can affect the interpolation drastically. Results of reconstruction of a real 3D object from multiple views are shown.

title: Managing personal documents with a digital library

authors: Jaballah, Imene

subjects: computer science

abstract: This paper presents a desktop system for managing personal documents. The documents can be of many types—text, spreadsheets, images, multimedia—and are organized in a personal “digital library”. The interface supports browsing over a wide variety of document metadata, as well as full-text searching. This extensive browsing facility addresses a significant flaw in digital library and file management software, both of which typically provide less support for browsing than for searching, and support relatively inflexible browsing methods. Three separate usability studies of a prototype—an expert evaluation, a learnability evaluation, and a diary study—were conducted to suggest design refinements, which were then incorporated into the final system.

title: Ngāti Whakaue Māngai Nui

authors: Hiini, Anaha Te Wheoro

subjects: Ngāti Whakaue Māngai Nui

abstract: Ko Ngāti Whakaue tētehi iwi ahurei o te waka o Te Arawa.  Ko tētehi taha ōna kei ngā tahataha o te kōroto moana o Te Rotorua-nui-a-Kahumatamomoe, i Waingaehe ki Waimihia.  Ko tētehi atu taha ōna kei te ūnga o te waka rongomaiwhiti o Te Arawa, arā ki Maketū.  
Kua whai mana a Ngāti Whakaue i ngā rautau e tū whakahīhī ai rātau hei iwi mana nui i ō rātau pūkenga me ō rātau pūmanawa kia mau tonu tō rātau Whakauetanga, tō rātau ahurea me ā rātau tikanga.   Ko tētehi pūkenga pēnei i te āheinga ki te whakairo i te kupu rōreka, ki te tuitui i te kōrero i whakaputaina ai te kōrero ‘Te Arawa Māngai Nui’.  He mea whakapuaki te kōrero rā e iwi kē ki te whakanui i ngā pūkōrero o ngā paepae o Te Arawa, ka mutu, koirā hoki tētehi pūkenga i hau ai te rongo o Ngāti Whakaue.  
Nā, ko te pūkenga e kōrerohia nei, ko te reo o Ngāti Whakaue.  Ko tōna oranga tonutanga te kaupapa matua o tēnei tuhinga e rangahaua ana i te putanga o te kōrero a tētehi o ngā koroua matatau o te iwi i te tau 1992, arā a Hamuera Mitchell, nāna tonu nei i whakapuaki ‘Ka mate te reo o Ngāti Whakaue ā te tekau tau’.  

Nō reira, he whakatewhatewhahanga tēnei tuhinga o te reo o Ngāti Whakaue o tua, o mohoa noa nei hoki kia mōhiotia ai te oranga, te matenga haeretanga rānei o te reo o te iwi, o ngā hapū, o te hapori, o te kāinga o nāianei, kia tau hoki mehemea āe rānei kua whai hua ngā rautaki reo o mua a Ngāti Whakaue ki te whakarauora i tōna ake reo, ā, ka aha te iwi e anga whakamua ai.  Ka mātaitia te āhua o te reo o Ngāti Whakaue kia mōhiotia mehemea i tika tā Hamera Mitchell i kī ai i te tau 1992, karekau rānei, mehemea rānei he wero kē nāna kia kaua e tukuna e te iwi o Ngāti Whakaue tō rātau reo kia mate.

Ko te tikanga rangahau Pākehā, ko te tikanga rangahau Māori, me ngā tikanga ako reo ka kaha mātaitia i tēnei tuhinga kia tika ai te kohinga o ngā raraunga o tēnei momo rangahau, ngā tikanga matatika a te wānanga, ngā tukanga tātari me te whakahōrapatanga atu i ngā whakataunga o te rangahau.  

Hei āpiti atu, ka kōrerohia ngā kaupapa mātauranga a Ngāti Whakaue, tae noa atu ki ngā tini kaupapa whakarauora reo a te iwi kua whakahaerehia mai i te tau 2005 ki ēnei rangi tonu nei mō te oranga o te reo o Ngāti Whakaue te take e anga tōtika atu ai ki te wetenga o te rautaki reo o mua a Ngāti Whakaue i whakahaerehia ai i ngā tau 2013 ki te tau 2017 i kitea ai ōna pikinga, ōna hekenga, ōna ngoikoretanga me ōna hua.  

Heoi anō, hei whaiwhai noa ake i te rautaki o mua nei, ko ngā mātātuhi kua mahue iho rā, ko te korenga o ngā arotakenga, ko te korenga o ngā pūrongo, ko te korenga o ētehi taunakitanga ā-tuhi nei, ko te korenga o tētehi aha kē atu rānei kia kitea he hua, he pikinga, he hekenga, he aha rānei.  Ahakoa tērā raru, nā te kitenga me te rongotanga o te pikinga haeretanga o te āhua o te reo, nā ngā kōrero ā-waha me ngā kauhau a ētehi mō ngā hua i puta ai i te rautaki reo o mua a Ngāti Whakaue i mana ai te whakahaumanutanga o te reo o ngā paepae o te iwi.

Nā te mea ko te reo Māori te remurere o te kaituhi nei, kua tekau mā waru tau ia e whai ana i te kaupapa i a ia e whakaako ana, i a ia e wānanga ana, i a ia hoki e whakapau kaha ana ki te whakaora anō i te reo Māori, kua whakaritea e ia tētehi rautaki reo hou e toru tekau tau te roa hei kōkiri mā te iwi e ora rawa atu anō ai te reo o Ngāti Whakaue, e whai hua anō ai hoki te whakapuakitanga o te kōrero rā ‘Te Arawa Māngai Nui’, hei tohu whakanui i ngā pūkenga kōrero o te iwi.

E ai ki te kōrero, ‘he tīmohea kua pakari’.  Nā roto i te āta rangahaua o te kaupapa nei i mōhio ai e ora tonu nei te reo o Ngāti Whakaue, heoi, kāore e pērā rawa te kaha o te oranga i te wā i a kui mā, i a koro mā.  Ahakoa te kōrero mō te matenga haeretanga o te reo o Ngāti Whakaue, nā ngā kaupapa whakaora reo a te iwi i ngā tau i piki anō ai te oranga o te reo, ka mutu, mā te whakahaerenga tonutanga o ngā wānanga nei e ora tonu anō ai te reo.
