Benthic macroinvertebrates are a frequently used indicator group for biomonitoring and biological assessment of river ecosystems. However, their taxonomic identification is laborious and requires special expertise. In this study, we aimed to assess the capability of a vision transformer (ViT) model for family-level identification of mayflies (order Ephemeroptera). Specifically, we focused on [...]
Applying the FEW nexus concept at the local scale
Published: 2021-04-01
Subjects: Civil and Environmental Engineering, Engineering, Environmental Studies, Social and Behavioral Sciences
The food-energy-water (FEW) nexus describes interactions among domains that yield gains or tradeoffs when analyzed together rather than independently. In a project about renewable energy in rural Alaska communities, we applied this concept to examine the implications for sustainability and resilience. The FEW nexus provided a useful framework for identifying the cross-domain benefits of renewable [...]
An Optical Scattering Based Cost-Effective Approach Towards Quantitative Assessment Of Turbidity And Particle Size Estimation In Drinking Water Using Image Analysis

Subjects: Business, Civil and Environmental Engineering, Engineering, Environmental Engineering, Life Sciences, Medicine and Health Sciences
Contaminated water consumption primarily for drinking purposes is the cause of approximately 502,000 global deaths every year mostly in economically challenging countries indicating the need for a cheap, easy to use a yet robust and scientifically proven method for determination of water quality. In this work, we have characterized the water quality utilizing the principles of optical scattering [...]
