Accurate projections of seasonal agricultural output are essential for improving food security. However, the collection information through surveys is often not timely enough to inform public and private stakeholders about crop status during growing season. Acquiring accurate estimates can be particularly challenging in countries with predominately smallholder farms because large number small plots, intense intercropping, high diversity types. In this study, we used RGB images collected from...
Timely and accurate agricultural information is needed to inform resource allocation sustainable practices improve food security in the developing world. Obtaining this through traditional surveys time consuming labor intensive, making it difficult collect data at frequency resolution accurately estimate planted areas of key crops their distribution during growing season. Remote sensing technologies can be leveraged provide consistent, cost-effective, spatially disaggregated high temporal...
Abstract Background The COVID-19 pandemic highlighted the need for early detection of viral infections in symptomatic and asymptomatic individuals to allow timely clinical management public health interventions. Methods Twenty healthy adults were challenged with an influenza A (H3N2) virus prospectively monitored from 7 days before through 10 after inoculation, using wearable electrocardiogram physical activity sensors. This framework allowed responses be accurately referenced infection...
<sec> <title>BACKGROUND</title> The risk of developing heat-related illness (HRI) increases when personal protective equipment (PPE) is worn, especially in hot and humid environments. While cooling strategies are effective, they must be applied preemptively or delivered promptly, which can difficult if individuals working dangerous environments wearing contaminated PPE. Wearable sensors leveraged to continuously monitor health including heart rate, respiration blood oxygen levels, physical...
Demonstration of an electrochemical toilet wastewater treatment and disinfection technology at the scale apartment building translation system into a commercial product.
Stress experienced by law enforcement officers is often extreme and in many ways unique among professions. Although past research on officer stress informative, it limited, most studies measure using self-report questionnaires or observational that have limited generalizability. We know of no attempted to track direct physiological responses high fidelity, especially within an operational police setting. The outcome this project will impact both practitioners policing researchers. To do so,...
Currently, the most common method for detecting prosthetic implant loosening is imaging. Unfortunately, imaging methods are imprecise in early signs of loosening. This paper describes a new wireless inductive proximity sensor system The accurately detected by analyzing electromagnetic field generated passive sensors located around implant. was modeled and simulated using COMSOL, then tested experimentally. metallic form coupled circuit tuned to oscillate at designed frequency. circuit's...
A challenge in water reuse for toilet flushing India and other Asian countries derives from pour practices. It is a common assumption that the amount of flushed used personal cleansing small comparison to cistern flush volume, however there knowledge gap regarding actual contribution each source blackwater amount. In this study, digital meters were measure fraction wash tap relative flushing. High temporal resolution measurements carried three different urban sites city Coimbatore southern...
The objective of this paper is to provide a definition for interface compression that uses essential principles engineering science. This discusses factors influence the amount applied pressure, including size limb, fabric tension (graduated pressure profile), number layers, and material creep characteristics. Laplace's law has been therapy. Tension-extension profiles have derived different types demonstrate effects resistance friction. Force-time systems (creep defined generally as...
Abstract Water quality and sanitation are inextricably linked to prevalence control of soil-transmitted helminth infections, a public health concern in resource-limited settings. India bears large burden disease associated with poor sanitation. Transformative onsite technologies being developed that feature elimination pathogens including eggs wastewater treatment. We conducting third-party testing multiple technology systems Coimbatore (Tamil Nadu) India. To ensure stringent the pathogen...

Medical compression hosiery is prescribed according to the pressure it applies a limb. There are many devices available for measuring this pressure, but differences in design of systems used, measurement locations, protocols, and operators result different pressures being measured same garment. This article explores construction these compression-measuring sensing involved order highlight potential causes discrepancies. The Tension–Elongation profiles six samples were then measured, method...
Abstract Electrolysis of blackwater for disinfection and nutrient removal is a portable scalable technology that can lessen the need cities to construct large‐scale wastewater treatment infrastructure enable safe onsite reuse blackwater. Several systems treating from single toilets are described in literature, but there few examples designed use electrolysis treat nearby toilets, which situation more common densely packed urban living environments. In order scale toilet system one could...
Adolescent stress is complex and impairing. Novel measures are needed to understand variability within individuals over time from a physiological as well subjective perspective. To test the feasibility of combining ecological momentary assessment (EMA) wearable biosensors assess adolescent stress, using an idiographic approach with experience sampling methods. A small sample (n = 23) predominantly African American, economically disadvantaged adolescents were asked complete EMA surveys four...
As outlined in compression therapy literature, the performance of a textile can be characterized by its stiffness and interface pressure. In this study, an indirect approach for measuring pressure from set bandages hosiery was developed, which rigidity (EI) values were determined, tension–elongation curves pressure-elongation data calculated. The calculated compared against PicoPress sensor readings measured on 10 participants. Results showed that correlation between both approaches varied...
