title: Migrants’ communication practices with ICTs: tools for facilitating migration and adaptation?

authors: Holmes, Prue

subjects: migrants

abstract: Migrants to a new homeland face significant adaptation and communication challenges. Information communication technologies (ICTs) are obvious tools to bridge these challenges. In this paper we investigate how migrants’ communication practices shape their use of email and the Internet as part of their settlement process, and consequently, their inclusion in and contribution to the community, economy, and society. The study used an experimental research design whereby student researchers undertook email and follow-up face-to-face interviews with 28 diverse migrants to New Zealand. The findings showed that their use of computer-mediated communication (CMC) was influenced by their preferred cultural communication practices in some instances, but not in others. CMC enabled migrants to make sense of their immigration/adaptation experience, as well as manage daily living, thus negating earlier research that “problematizes” migrants with respect to technology use and adaptation. Yet, this empowerment did not necessarily facilitate intercultural communication or cultural inclusion. Further, both inter- and intra-cultural communication differences emerged, especially in relation to trust and emotion, and in differences between CMC and face-to-face communication: ICTs are not neutral tools for communication. Yet, migrants valued CMC as a tool for long term economic integration with potential widespread results for success in the host society. The outcomes of the study indicate the need to research cultural groups both separately and within, and the need to explore migrants’ economic and social contributions to the receiving society through ICT uptake.

title: Ultrasonic Air Leak Detection: An Investigation to Improve Accuracy of Leak Rate Estimation

authors: Wolstencroft, Hamish Roger

subjects: ultrasonic

abstract: A compressed air test rig was designed to develop new procedures and improve the reliability of results that are obtained when conducting a leak survey using an Ultrasonic leak detector such as the UE Systems Ultraprobe.

A test rig was designed that allowed the pressure of air in a compressed air system to be controlled by a regulator. This allowed experiments to be conducted that were able to recreate leak situations in a controlled environment. The pressure of the air through the test rig was measured both at the supply end and at the proximity of the leak site, while the volume flow rate was measured at the supply end of the rig.

A number of leak geometries were examined, with compressed air being passed through open ended tubing and also discs with different leak geometries, some round holes and some rectangular. Initial studies were also carried out on flange leaks and pinpricks and slits in lengths of tubing. These were omitted from the study at this stage to allow further experimentation to be conducted in both areas.

The experimentation was carried out using an Ultraprobe 9000 leak detector which was positioned at a set distance from the leak at a series of angles to the flow. The ultrasound level was measured at each point and compared with the pressure and volume flow rate of the air in the system.

The results showed that the ideal angle to ensure the maximum level of ultrasound is at 30 to the axis of the leak. While the optimum distance for ensuring a consistent level of ultrasound is 150mm from the leak.

The length of any air lines branching from the main distribution network is shown to be an important factor when quantifying the volumetric flow rate of air from an open ended tube or tubing with a significant orifice in it. The pressure drop in a 1m length of tubing was shown to be approximately 50%, and if you consider that often the flow rate being used has been obtained using the outside diameter of the tubing rather than the inside diameter this can become a considerable over estimation of leak rate.

The geometry of a regular shaped orifice, such as a round, or rectangular hole was shown to have little to no effect on the flow rate through it for a constant area. However a coefficient of discharge to account for imperfections in the flow was developed for round and rectangular geometries, these were 0.74 for a round hole and 0.79 for a rectangular hole. These correction factors in tandem with the length effect factor for tubing and the improvements to the measurement procedure, allow a higher degree of accuracy to be obtained when conducting a leak survey.

Ko te tāhu o tēnei tuhituhinga he titiro ki Te Hāhi Ringatū i runga o Whitianga marae. E rua noa iho ngā Rā Ringatū ka tū ki runga i tēnei marae, arā, ko Te Huamata, hei te tahi o Hune tēnā me Te Pure, hei te tahi o Nōema tēnā. I roto i te tuhituhingaroa nei ka titiro he aha I tae atu ai wēnei tikanga ki tēnei o ngā marae. Ka whakatakoto haere, i pēhea hoki ngā whakahaeretanga i te wā o ngā pakeke. Kātahi ka titiro ki ngā whakarerekētanga ki ngā tikanga i roto i te wā, ā, he aha i pērā ai. 
Kua tata ki te toru tekau tau mai i te whakakoretanga o Te Māratapu a Te Ringatū i roto i wāna whakahaerenga i Te Huamata me Te Pure. Ko tērā tūāhuatanga o Te Ringatū e kore nei e kitea e tēnei reanga tangata.
Tokoiti noa nei, me kī, ngā mōrehu o tērā whakatipuranga pakeke i kitea wērā tūāhuatanga e ora tonu ana. Nō reira i toko ake te whakaaro ki te rangahau, ki te kohikohi hoki i ngā kōrero i te hunga i rongo, i kite, i tipu ake hoki i roto i tērā Ao. He pekanga nui o te tuhinga nei kua titiro ki Te Huamata me Te Pure me wōna tapu, me wōna whakahaerenga ki runga o te marae o Whitianga.
Ki te whakawhāriki i ngā kōrero nei mō Te Ringatū ki runga o Whitianga kua tātaritia kia waru ngā pekanga o te tuhinga kia mārama ai ki te karu pānui i ngā kōrero; i pēhea tae atu ai Te Ringatū ki runga o Whitianga, i pēhea tāna kawe i ngā tikanga, ā, he aha i whakarerekēngia ai tāna kawe i Te Huamata me Te Pure i roto I te wā.
