      The brine mining equipment failure can seriously affect the productivity of the salt lake chemical industry. Traditional monitoring and controlling method mainly depends on manned patrol that is offline and ineffective. With the rapid advancement of information and communication technologies, it is possible to develop more efficient online systems that can automatically monitor and control the mining equipment and to prevent equipment damage from mechanical failure and unexpected interruptions with severe consequences. This paper describes a Wireless Monitoring and feedback fuzzy logic-based Control System (WMCS) for monitoring and controlling the brine well mining equipment. Based on the field investigations and requirement analysis, the WMCS is designed as a Wireless Sensors Network module, a feedback fuzzy logic controller, and a remote communication module together with database platform. The system was deployed in existing brine wells at demonstration area without any physical modification. The system test and evaluation results show that WMCS enables to track equipment performance and collect real-time data from the spot, provides decision support to help workers overhaul the equipment and follows the deployment of fuzzy control in conjunction with remote data logging. It proved that WMCS acts as a tool to improve management efficiency for mining equipment and underground brine resources.
    • Managing the sublime aesthetic when communicating an assessment regime: The Burkean Pendulum

      Kofinas, Alexander K. (SAGE, 2017-12-26)
      The importance of understanding students’ engagement is prominent in higher education. Assessment is a main driver of student engagement, a phenomenon known as backwash. I argue that students’ engagement with learning is often driven by an aesthetic motivation. I establish the connections between Burke’s (and Kant’s) conceptualisation of aesthetics as a dichotomy of beauty and the sublime (which I label the Burkean pendulum) to motivation. I explore the links between this aesthetic motivation and the assessment regime focusing on the Burkean/Kantian sublime and suggest four communication strategies to manage the sublime when it arises in students’ education journeys. My contributions are twofold:firstly, I introduce the Burkean Pendulum as a means for educators to reflect on the aesthetic aspects of their designed assessment regimes. Secondly, I propose a framework of communication strategy narratives (Thriller, Horror, Exploration, and Action) that could be used to manage the sublime of the assessment regime.
