title: Mixed signal approach for rapid prototyping of a compact smart pebble for sediment transport monitoring in river beds

authors: Kularatna, Nihal

subjects: MEMS

abstract: Low-cost accelerometers and gyro ICs were used to develop a smart sediment particle to study the sediment transport in rivers. With strap-down MEMS, battery, a processing subsystem and memory, this self contained unit captures semiprocessed data for durations up to 15 minutes. In a mixed-mode design, analog multiplier ICs with limited digital circuits transform the body frame data to a reference frame using Euler angles, with adequate accuracy despite cumulative errors. For 3D motion, up to nine sensor inputs from three orthogonal modules are coupled to a multiplexed analog processing module, and processed by a digital module for data conversion and storage. Despite the simplified mathematics used, experimental data from the proof-of-concept system provided adequate accuracy. Subsequent processing of the raw sensor data using an external PC program with smart algorithms allowed the comparison of accuracy of the mixed mode approach. The adopted mixed signal design approach helps the packaging requirements due to the specific nature of the problem with short recording durations.

title: Indigenous data sovereignty

authors: Rainie, Stephanie Carroll

abstract: • Indigenous Data Sovereignty (IDS) has emerged as an important topic over the last three years, raising fundamental questions about assumptions of ownership, representation, and control in open data communities. 
• IDS refers to the right of Indigenous peoples to control data from and about their communities and lands, articulating both individual and collective rights to data access and to privacy.
• Ideas from IDS provide a challenge to dominant discourses in open data, questioning current approaches to data ownership, licensing, and use in ways that resonate beyond Indigenous contexts, drawing attention to the power and post-colonial dynamics within many data agendas.
• Growing IDS networks are working to shape open data principles to better respect the rights of Indigenous peoples.
