title: Detecting relay attacks against Bluetooth communications on Android

authors: Symon, Jeremy

abstract: The widespread usage of mobile devices has lead to mobile devices being used to replace existing solutions, including smart cards for authentication in access control systems. While this can be convenient, there are security concerns which must be addressed. One such concern for access control authentication is relay attacks, which are more difficult to prevent when using Bluetooth on a mobile device rather than smart cards. This thesis investigates an alternative method of detecting relay attacks, using sensors present on typical mobile devices to fingerprint a location. As opposed to other research, this approach uses only the sensors available on a single mobile device, in order to be compatible with existing access control systems that do not have specialised sensors. The proof of concept shows several sensor types are strong indicators of location, particularly observable WiFi signals.

title: Housing First in Hamilton: Who were first housed?

authors: Atatoa-Carr, Polly

subjects: Homelessness

abstract: The People’s Project (TPP) in Hamilton (NZ) is a collaborative effort between 13 local organisations which takes a Housing First approach to homelessness. A Ministry of Business, Innovation and Employment funded collaboration between the Universities of Waikato and Otago and TPP has allowed the gathering of evidence regarding the Housing First approach to homelessness in Hamilton, the people served, and their engagement in services in the years leading up to registering for support. A better understanding of the sociodemographic characteristics, as well as the specific needs and experiences of this cohort, helps to consider how to most appropriately implement the principles of Housing First to meet the requirements of the local population and contex.

title: Boat electrofishing salvage of fish in the Lower Mangamahoe Dam reservoir

authors: Hicks, Brendan J.

abstract: The aim of the survey was to salvage fish from the Lower Mangamahoe Dam reservoir before dewatering and dam removal. We used the University of Waikato’s 4.5 m-long, aluminium-hulled electrofishing boat to catch a total of 140 fish weighing an estimated 37.0 kg along 8 fishing tracks sites on 24 February 2022. These tracks comprised 2,807 lineal m and 11,228 m2 in area. Shortfin eels (Anguilla australis) and common bullies (Gobiomorphus cotidianus) were the only fish species present. Mean density of eels caught was 2.9 fish 100 m–2 and mean biomass was 7.84 g m–2. The eels and bullies were transferred to sites downstream in the Waiwhakaiho River by iwi members of the two hapū - Ngāti Te Whiti and Ngāti Tawhirikura. Water clarity, expressed as black disc distance (BDD, 1.05 m), was good for a shallow lake, and water temperature and water conductivity were close to optimum for electrofishing. Poor water clarity can reduce the efficiency of electrofishing, so we left time after fishing each track for the sediment suspended by the propellor wash to sink before refishing a track.
