title: Impact of circadian tuning on the illuminance and color uniformity of a multichannel luminaire with spatially optimized LED placement

authors: Abeysekera, Sanush K.

subjects: Science & Technology

abstract: Potential advantages offered by multichannel luminaires with regards to spectral tuning are frequently overshadowed by its design challenges, a major one being the non-uniformity in illuminance and color distribution. In this paper, we present a formulation using genetic algorithm (GA) to optimize the Light Emitting Diode (LED) placement, yielding 40% superior uniformity in illuminance and color distributions compared to existing analytical formulations, substantially reducing the reliance on optical design for this purpose. It is specifically shown that our approach is employable for circadian tuning applications, even when heavily constrained by industry specifications on panel size and minimum LED separation.

title: Exploring the impact of internet on hospitality industry's marketing practices: A case of Hamilton, New Zealand

authors: Kumar, Bhupesh

subjects: internet

abstract: This study assesses the impact `internet’ has had on marketing practices of hotels and other sectors of the hospitality industry. Debate continues to establish a definitive image for internet marketing and assess its impacts.  The current study draws upon the literature review undertaken for the purposes and options of senior industry people accumulated through in-depth interviews The interview analysis focused on five criterions based on type of the respondent, their current marketing practice and future intentions regarding internet as a marketing tool.  An agglomerated analysis illustrated that although internet may be more powerful than traditional marketing, traditional marketing still enjoys good popularity within masses. Internet as a fast growing entity by itself, requires the company managers to give it a strong consideration as part of company polices and be prepared to adapt changes as they arise.

title: Na Tarimo i whakaari... Ko Rangiwewehi te iwi

authors: Flavell, James William Ben

abstract: Ko ngā kōrero e whai ake nei, he mea kohikohi, he mea tuku mai ki ahau mō te iwi e kiia nei, ko Ngāti Rangiwewehi. Ko te rohe ki te taha raki o te Rotorua-nui-ā-kahumatamomoe to tūrangawaewae, otirā the rohe takahi o te iwi nei, i ngā rā o mua, nā, ahakoa he nui te whenua kua ngaro atu, kei konei tonu te papa kāinga mō tēnei karangatanga o Te Arawa waka, kei konei hoki tōna mauri, tōna mana, tōna wehi.
Ko Ngāti Rangiwehei i ēnei rā, e rite tonu ana ki te tōtara nui. I tipu ake tēnei tōtara i te kākano i ruia i Rangiātea arā, i Hawaiki, i mānu mai ki Aotearoa nei, i puāwai mai, ā, kei te tipu tonu, kei te tuipu tonu.
Nā, kei roto i tēnei rākau, ko ngā kōrero katoa mō te iwi nei, arā ko ngā whakapapa, ko ngā waiata ko ngā karakia, ko ngā pakiwaitara otirā ko ngā āhuatanga katoa e pā ana ki te iwi. Kei konei hoki ko te ira o te tangata e mau nei i ēnei āhuatanga nei.
Ka tae ki te ngahuru, ka heke iho ngā rau rākau ka pirau, ka ngaro. Pēnei i te rākau nei, te hinga te tangata, ka kapohia e te ringa o Aituā, ā, ka ngaro. Ēhara i te mea ko te mauri o te tangata anake te mea e ngaro nei, ēngari, ko ōna mātauranga katoa hoki.
Nā, matemate noa atu ngā koroua me ngākuia e mōhio tūturu ana ki ngā kōrero hōhonu tuku iho a Ngāti Rangiwewehi. Nō reira, ko tāku mahi, he kohi i ēnei kōrero, i mua i te ngaronga tonutanga o ngā kaumātua e ora ana, nei ngaro.
Kua kohia nei e au ngā kōrero katoa ahakoa Māori ahakoa Pākehā, kia kitea ai, kia mārama ake ai ngā momo āhuatanga o tōku iwi.
Ēhara tēnei i te me ngāwari, nō te mea, ko tēnei mea te mātaranga ahakoa he whakapapa rānei, he pakiwaitara rānei, he mea tino tapu ki te Māori, i te ao tawhito, ā, kei te pērā anō hoki i ēnei rā. Kua oti te tārai te tāhū o tēnei tuhituhinga e kore a taea te whakatārewa tēnei tāhū mehemea kāore, ōna pou kāore ōna here e tika ana. Otirā e kore e tū te whare kōreo, te tāhū whakaringa kōereo, mehemea kāore ōna kaupapa whenua, tangata, tae atu ki a Papatūānuku. Nō reira, koia tēnei ka tātaihia ake ngā kupu kōreroa muri ake nei, kia tutuki ai ngā tūmanako ngā wawata, a ngā whakatipuranga, mai, mai, mai i te pō ki ngā kaikōrero me te kaituhi.
E ai ki te iwi, ko Rangiwewehi te tipuna o tēnei iwi te tamaiti a Tawakeheimoa rāua ko Te Aongahoro.
Nā te mea, he karangatanga a Ngāti Rangiwewehi nō Te Arawa waka i hoki atu ai au ki ngā kōrero mō tēnei waka tapu. Tae rawa mai tēnei waka ki tēnei whenua, ka horapa hāere ngā tāngata i te mata o te whenua. I tōna wā, i tae atu ngā tīpuna ke Te Awahou awa, otirā ki te taha raki o Rotorua moana. Mai i taua wā, ka tīmata ngā āhuatanga katoa e pā ana ki tēnei iwi.
Nā, ēhara tēnei tuhinga i te pukapuka hei whakaatu i te tūturutanga o ngā kōrero katoa o Ngāti Rangiwewehi, mā Ngāti Rangiwewehi hei whai atu, ēngari he kōrero kua kohia nei e au i ngā rangatira, i ngā tohunga, i ngā tāngata mōhio, i ngā whāea, i ngā kaumātua me ngā pukapuka a ngā Māori me ngā Pākehā.
He pūtake kōrero noa iho tēnei mō Ngāti Rangiwewehi he tohu whakamaharatanga hoki ki ngā tīpuna, ki ngā mātua kua wehe atu nei ki te pō.
