Evangelical Quakers and Public Policy
In Arthur Roberts\u27 excellent volume reflecting on his life, Drawn By The Light, he briefly describes his involvement in state and local politics. He ran unsuccessfully for a position in the Oregon Legislature and later served a four-year term on the Yachats, Oregon, City Council. It was not easy for Arthur to bridge the gulf between the intellectual depth and erudite vocabulary of the scholar and the rough and tumble of state and local politics. But he felt that these political involvements had quickened my appreciation for ordinary activity as the true vocation for the church. Arthur took his city council work very seriously, devoting a great deal of time to preparing for the meetings. He also took seriously the opportunity to bear witness to his faith in Christ and had numerous opportunities to speak to others about that faith
Programming a Microcontroller to Drive a Fisher & Paykel SmartDriveā¢ Washing Machine Motor to Power a Go-Kart.
Microcontrollers are one of the basic building blocks of the āInternet of Thingsā. In this paper, I describe the tools and processes needed to program a STM32F302R8 microcontroller to drive a Fisher & Paykel SmartDriveā¢ brushless direct current motor. The motor is used to power a go-kart. The STM32F302R8 is an ARMĀ® CortexĀ®-M4 microcontroller, programmed with the āCā programming language. The F&P SmartDriveā¢ motor is a brushless direct current motor, which relies on a microcontroller unit to provide commutation for the coils
Assisted Living: Domestic Power Monitoring utilising Home Automation Products and Cloud Storage
This paper describes the development of a system for taking measurements of electrical power consumption in a domestic situation and using a web service to store the measurements in a cloud hosted database. This is part of a larger project to evaluate the potential for using power monitoring as a proxy for wellness as part of the assisted living projects at Wintec
A minimally intrusive monitoring system that utilizes electricity consumption as a proxy for wellbeing
The purpose of this work was to test the hypothesis: `Off-the-shelf domestic electricity meters can be utilised to assist in monitoring the wellbeing of elderly people` Many studies have shown that it is,
in theory, possible to use domestic electricity consumption to determine `activities of daily living` but the availability of systems for actual use is very limited. This work followed the Design Science
Research Methodology to create a Java application running on the Google App Engine cloud service that interfaced with both electricity meters and voice and text services. The system was implemented
and tested over a three month period with one older person and their carer. Results demonstrated that the technology readily succeeds in meeting the study`s initial objectives. The need for more
sophisticated decision logic was apparent and a method to determine whether a home is currently occupied is likely to improve the ability to create more timely alerts
Off-the-shelf Non-Intrusive Load Monitoring Devices Utilised in a Low Activity Detection Service
There is a growing awareness for the need to provide low cost solutions for the care of the elderly and in particular to allow them to keep living independent lives. In parallel to this there has also been significant advances in a number of technical areas including 1) monitoring electricity consumption for the purpose of reducing power costs, 2) non-intrusive load monitoring (NILM), 3) using sensors to determine activities of daily living and 4) cloud computing. The purpose of this work was to demonstrate that it is possible to use a readily available consumer off the shelf electricity monitor to provide a low intrusive activity monitor for older persons. This work uses the Design Science Research Methodology and builds on the results of our previous work that used raw electricity usage data. In this work we are trailing the use of a meter that uses NILM to identify individual appliances in the home. The information on appliance use was analysed by a cloud base program and alerts were sent to the carer when lower than expected activity was detected. Participants both in this work and those reported in the literature have mentioned the annoyance of having multiple sensors in a home, especially if they emit either constant or flashing light. In contrast NILM allows the use of multiple electrical appliances to be monitored without the need for a large number of sensors to be deployed ā just one sensor at the meter or fuse board. The confluence of a number of technologies has enabled the creation of a low intrusive and low cost monitoring system to have become a reality. The initial trial of the system has been shown to be a mostly reliable alternative to a system built on multiple sensors. Based on previous work that involved the deployment of multiple sensors, the new system is expected to be more acceptable as it has the desired attribute of becoming invisible to the user
Low-cost rapid authoring tool for Moodle quizzes
ABSTRACT This paper describes the motivation and development of a desktop application developed by the authors called Question Machine (QM). It rapidly creates electronic quizzes that can be imported into Moodle. It is being evaluated by students doing a userinterface design course
