A Remote Area Power Supply (RAPS) Training Facility utilising SMA Sunny Island Inverter technology and National Instruments measurement package
Get PDFRAPS systems can sometimes be a cheaper alternative for supplying power than connection to a distant utility. Most assuredly it is a cleaner method of producing electricity than coal or gas constituents, provided the diesel generator is used minimally. A modern RAPS system will generally have several sources of generation, typically they might be; solar, wind and a diesel/petrol generator coupled with a battery to store excess power. The RAPS 2 system at Murdoch University was selected for an overhaul early in 2010. The system was redesigned to include new inverter technology from SMA. The new system relies on 3 separate inverters to convert the sources directly into grid quality electricity, as opposed to some traditional RAPS systems that would have most of its elements feed a DC bus that connected to a single inverter. This novel way of setting up a mini grid finds its niche in situations when the terrain or meteorological conditions make it impractical to have generation equipment all localised and a DC bus would have higher associated cable losses.
For such a system to be of educational benefit to tertiary students, the variables within the system must be able to be monitored. To this end an advanced measurement system has been designed and procured so that every measurable point in the upgraded system is available for display.
The measurement system was designed using National Instruments compact DAQ (data acquisition) hardware, one of the first of its type to be introduced to the university. The compact DAQ unit has been coupled with isolation equipment supplied by Dataforth, which already has an existing prevalence throughout the engineering department. The subsequent measurement program monitors 31 system variables at a high sampling rate to provide real time information on the state of the system. The measurement program also monitors relevant meteorological aspects such as the solar irradiance and local wind speed.
This report documents and details the steps taken to set up a new and novel RAPS system. Discussed are the approaches taken throughout the semester to project manage and facilitate progress. A detailed description is also given of the measurement and protection system that has been designed to allow students and the general public to get a good grasp on the performance of the system
Attention Capture by Action Effects are Driven by Prediction Error Minimization
No full textPreviously, we showed that stimuli that are considered as action-effects are processed with priority (Kumar, Manjaly & Sunny, 2015). We considered the role of common-coding mechanisms in driving this effect. However, recent studies suggest that these effects may follow the principles laid out by the predictive coding framework. In the present study, we explore how predictions about various parameters involved in action-effect monitoring (location, SOA, contingency) modulate attention capture by an action effect. In five experiments we investigate the effects of uncertainty associated with these characteristics in driving attention capture. Specifically, a reliable prediction error driven by controlled irregularity seems critical for automatic processing of action effects. Moreover, in case of high regularity or high irregularity the visual system uses minimal information from the environment and hence attention control appears to be top-down. The findings present robust evidence supporting the role of predictive coding mechanisms in driving automatic processing of visual information
Q&A on Sunny Singh’s short story A Cup Full of Jasmine Oil
No full textWith its rich semantic texture and evocative imagery Sunny Singh’s short story A Cup Full of Jasmine Oil invites various readings. The story tells how a young girl is both attracted and confused when her grandmother’s neighbor, who lives in a lesbian relationship, massages her skull and oils her curly hair. When the grandmother at one point forbids the oiling sessions, the girl suddenly becomes aware of hidden meanings and intuitions associated with this practice. The essay juxtaposes a reading of the story from a more conventional western perspective with an interpretation from the point of the Indian system of aesthetics based on rasa. From this double perspective, it discusses various stylistic and thematic aspects of the story. Diverging interpretations are presented of the role of the characters, the functionality of their characterization, and the use of description and suggestion to evoke the semantic framework of the story. The juxtaposition of two readings was prompted by a discussion with the author during a conference panel on rebellion in modern Indian literature and film. To prevent the impression of imposing a “scholarly” reading on a more “intuitive” reading, the essay continues the dialogue with the author and invites her to react to the reading and discuss the notion of an “Indian” aesthetic model, its relevance for her writing, and current critical approaches to modern Indian fiction. In her response, Sunny Singh explains how the theme of the story was prompted by her perception of the sharing of knowledge of sexuality and intimacy in a tightly-knit Indian social context. The discussion with the author extends beyond the specific story, and she presents her views on how her scholarly knowledge of modern Indian culture stimulates her in her creative work. Thereby, it aptly frames the exploration of a reading of A Cup Full of Jasmine Oil from the perspective of Indian literary aesthetics
Sunny: Arizona State University's Chatbot for Students
No full textabstract: Next year, Arizona State University is launching a chatbot that will place their knowledge and services right into the palms of their students’ hands. Currently named Sunny, this virtual assistant will be able to answer questions regarding all aspects of college life, from orientation to housing, financial aid, schedules, intramurals, and more. Over the last semester, I have met with members of the Sunny development team to discuss their design and implementation plans. With their information plus a bit of outside research, I was able to combine several frameworks and technologies to build a prototype for Sunny. Prototypes allow developers to evaluate their designs early on, giving them ample time to make any necessary adjustments. I am confident that the Sunny development team will be able to learn from my basic implementation, from its triumphs and failures, to create the best possible chatbot for the students attending Arizona State University

Promoting Wellbeing with Sunny, a Chatbot that Facilitates Positive Messages within Social Groups
No full text© 2020 Owner/Author. A Facebook Messenger chatbot, Sunny, was designed and deployed to promote positive social connections and enhance psychological wellbeing. A 10-day study was conducted with three pre-existing social groups of four members each in control (n=12) and experimental groups (n=12). Both groups completed initial assessments and daily reports, and the experimental groups interacted with Sunny. Exit interviews indicated three key themes: 1) Sunny prompted self-reflection, boosting participants' senses of self-worth and the depth of their relationships, 2) using Sunny encouraged participants to send heartfelt messages they would not have shared otherwise, 3) participants enjoyed accessing positive messages "on-demand". Experimental groups showed an average increase in psychological wellbeing of 1.73 (std = 6.08), compared to 0.5 (std = 5.94) in control. Our results suggest that an AI-based chatbot like Sunny could provide preventative care, promoting strong social connections and psychological wellbeing

Groundwater depletion in a changing climate: global insights and strategic mitigation approaches
No full textWater shortage, intensified by climate change and poor management, presents a substantial risk to global sustainability, and human security. Increasing temperatures and unpredictable precipitation patterns hinder water accessibility, especially in susceptible areas like the Middle East and East Asia, where economic development may suffer owing to agricultural deficits and health repercussions. Presently, more than 2.4 billion individuals experience water stress, with disadvantaged areas being disproportionately impacted. Primary factors contributing to water shortage are population expansion, urban development, and contamination, which exert pressure on limited freshwater supplies. Inefficient agricultural techniques constitute over 72% of worldwide water withdrawals, exacerbating the situation. The ramifications surpass resource depletion; water insecurity incites migration, war, and fluctuations in food prices. Nonetheless, remedies are available. Coordinated policies that advocate for effective water distribution and infrastructure investment can bolster resilience. Innovations like wastewater recycling and climate-smart agriculture exemplify scalable success. Mitigating water shortage necessitates international cooperation and balanced resource allocation. Safeguarding ecosystems while promoting technology such as desalination is essential for ensuring sustainable water futures. Immediate action is essential to alleviate the effects of climate change on water supplies and provide a reliable supply for future generations
Implementation of ODOT tack coat technologies and procedures to improve long-term pavement performance
No full textUsing direct shear testing, this study quantified the impact of new emulsions from three companies on bond strength as compared to emulsions traditionally used in Oregon. Additionally, this study focuses on developing and implementing a more robust set of specifications and QC provisions for tack coats. By improving upon and implementing the OreTackBond (formerly known as OFTT), a rigorous in-situ test for tack coat quality is validated for large-scale implementation as part of the highway construction inspection process. In this study, a wireless scale system that can be controlled from a tablet computer, (OreTackRate) was also developed to measure application rate accuracy and uniformity during construction. A field test procedure using OreTackRate was also developed to determine tack coat curing time to avoid tracking during construction. Using the OreTackRate system, a distributor truck certification and validation process was also developed. A construction surface cleanliness test (OreTackClean) and a test procedure were also developed in this study to reduce tracking and achieve more uniform tack coat distributions that will ultimately improve long-term tack coat performance. This study will advance the knowledge of engineered emulsion performance, usher in more precision in highway construction in Oregon and promote sustainability of the asphalt industry by creating pavement structures that meet or exceed their structural design lives by facilitating proper interlayer shear strength from well-controlled tack coat application.by Erdem Coleri, PhD; Blaine Wruck; Shashwath Sreedhar; Richard Villarreal; Sunny Lewis; Vikas Kumar, School of Civil and Construction Engineering, Oregon State University ; for Oregon Department of Transportation, Research Section and Federal Highway Administration.Title from PDF title page (viewed on March 19, 2020)."Project SPR 818.""FHWA-OR-RD-20-03"--Technical report documentation page.Covers OCLC #1145279454 and OCLC #1029201765.This archived document is maintained by the State Library of Oregon as part of the Oregon Documents Depository Program.
