    Performance of NO, NO<sub>2</sub> low cost sensors and three calibration approaches within a real world application

    Low cost sensors for measuring atmospheric pollutants are experiencing an increase in popularity worldwide among practitioners, academia and environmental agencies, and a large amount of data by these devices is being delivered to the public notwithstanding their behaviour, performance and reliability are not yet fully investigated and understood. In the present study we investigate the medium term performance of a set of NO and NO2 electrochemical sensors in Switzerland using 3 different regression algorithms within a field calibration approach. In order to mimic a realistic application of these devices, the sensors were initially co-located at a rural regulatory monitoring site for a 4–month calibration period, and subsequently deployed for 4 months at two distant regulatory urban sites in traffic and urban background conditions, where the performance of the calibration algorithms was explored. The applied algorithms were Multivariate Linear Regression, Support Vector Regression and Random Forest; these were tested, along with the sensors, in terms of generalisability, selectivity, drift, uncertainty, bias, precision and suitability for spatial mapping intra-urban pollution gradients with hourly resolution. Results from the deployment at the urban sites show a better performance of the non-linear algorithms (Support Vector Regression and Random Forest) achieving RMSE < 5 ppb, R2 between 0.74–0.95 and MAE between 2–4 ppb. The combined use of both NO and NO2 sensor output in the estimate of each pollutant showed some contribution by NO sensor to NO2 estimate and vice-versa. All algorithms exhibited a drift ranging between 5–10 ppb for Random Forest and 15 ppb for Multivariate Linear regression at the end of the deployment. The lowest concentration correctly estimated, with a 25 % relative expanded uncertainty, resulted in ca. 15–20 ppb and it was provided by the non-linear algorithms. As an assessment for the suitability of the tested sensors for a targeted application, the probability of resolving hourly concentration difference in cities was investigated. It was found that NO concentration differences of 5–10 ppb (8–10 for NO2) can reliably be detected (90 % confidence), depending on the air pollution level. The findings of this study, although derived from a specific sensor type and sensor model, base on a flexible methodology and have a large potential to explore the performance of other low cost sensors, different in target pollutant and sensing technology

    House Guests : The Grange 1817 to Today

    No full text
    "Built by the Boulton family between 1817 and 1820, The Grange is Toronto's oldest remaining brick house and a national historic site. The Grange was bequeathed at the beginning of the twentieth century to become the home of Toronto''s first art museum. During the nineteenth century, The Grange was at the centre of this city's social and political activity. Today, with its collection of furniture, artifacts and art, it is an historic house museum and a unique part of the Art Gallery of Ontario. The house embodies the AGO''s development over the past century, when it grew to become the eighth largest art museum in North America. The works of several contemporary artists will be special 'guests' in The Grange, the Gallery's first home, in celebration of the Art Gallery of Ontario's first century and the fact that the Gallery was founded with the work of then living artists. The exhibition, which is entitled House Guests: Contemporary Artists in The Grange, provides the opportunity to interweave our past and our future. Drawing upon the continuous transformations that have characterized The Grange, its holdings and its social and cultural role, these artists have been invited to respond to this rich site with works that will be installed throughout the house. This co-mingling of historical and contemporary forces will reveal our artistic heritage as the living legacy from which many current artistic practices are fashioned. The exhibition will be accompanied by the publication of a book, featuring an essay about The Grange by Charlotte Gray, author of Sisters in the Wilderness. The artists participating in House Guests will provide commentary on their installations and the impact that the house and its place in Toronto's history and culture had on their creative process.

    John Dewey, Confucius, and Global Philosophy

    No full text
    Bringing together the philosophies of John Dewey and Confucius, this work illustrates a means for cultural interaction and provides a model of global philosophy. Joseph Grange\u27s beautifully written book provides a unique synthesis of two major figures of world philosophy, John Dewey and Confucius, and points the way to a global philosophy based on American and Confucian values. Grange concentrates on the major themes of experience, felt intelligence, and culture to make the connections between these two giants of Western and Eastern thought. He explains why the Chinese called Dewey A Second Confucius, and deepens our understanding of Confucius\u27s concepts of the way (dao) of human excellence (ren). The important dimensions of American and Chinese cultural philosophy are welded into an argument that calls for the liberation of what is finest in both traditions. The work gives a new appreciation of fundamental issues facing Chinese and American relations and brings the opportunities and dangers of globalization into focus. “…Grange’s presentation of Dewey’s philosophy of experience and culture as well as the parallels he develops with Confucianism are truly valuable contributions to the field of comparative philosophy.” — Philosophy East & West “…a slim but important book for next steps in the world philosophical conversation. Grange is a subtle and creative thinker, and this volume whets the philosophical appetite for more in an increasingly shrinking global village.” — Dao Grange draws upon his sustained and substantial reading of the original reflections of John Dewey and of Confucius to bring into focus several seminal ideas from each of these two traditions that provide us with a resonance between them, and that can serve us as the terms of art necessary for undertaking such a Sino-American dialogue. — from the Foreword by Roger T. Ames Grange writes with a sure mastery of the relevant texts and secondary literature. His grasp of Dewey\u27s vast corpus is outstanding and his explication of Confucius\u27s ideas is crisp and on the mark. Grange is able to elicit connections between Confucius and Dewey without straining expert credulity or merely saying the obvious. — Robert Cummings Neville, author of Boston Confucianism: Portable Tradition in the Late-Modern Worldhttps://digitalcommons.usm.maine.edu/facbooks/1106/thumbnail.jp
