Landfill leachate is a complex wastewater composed of organic carbon, nitrogen compounds, dissolved solids, and heavy metals. Leachate characteristics may differ depending on the waste landfilled, climate conditions, and landfill age. Because of the toxic and recalcitrant nature of its constituents, landfill leachate wastewater (LLW) must be treated before being released to the environment. There […]

Open-ended questions are where respondents consider hypothetical scenarios that they might encounter in real life and describe what action(s) they might take in response to each situation. To assess a test-taker’s responses to these questions, a human scoring process (i.e., human raters marking each response individually) is followed. Despite following clear scoring criteria, human raters […]

There has been an increased commitment to capping GHG emissions from oil/gas (O/G) operations. However, reliable monitoring and quantification of methane emissions from particular sources are difficult for several reasons: (1) high-resolution sampling data over an extensive geographical area is rare; (2) identifying emission sources from large-scale monitoring satellite data is extremely challenging, often yielding […]

Calves are born without antibodies needed to fight off disease. The only source of antibodies available for the first few weeks of a calf’s life comes from maternal colostrum, the first milk produced by the cow. Calves are able to absorb these antibodies for approximately 24 hours of life, and absorption rates vary widely. Currently, […]

AltaML is a purpose-driven organization, with a mission to apply AI to elevate human potential. We describe ourselves as an Applied AI Studio, meaning we operate as a venture studio for applied AI. We work with large organizations through Corporate Lab engagements, continuously examining different AI use cases and moving the most valuable models to […]

The goal of this project is to train and test a machine learning algorithm to detect pharmaceutical contaminants in water. Surface nanodroplets will be generated for several key compounds. These, will be used as independent extraction medium with varying contaminant concentration. The large number of droplets will enable collection of a high quality training data […]

Sequestration of atmospheric and industrial CO2 through carbonation of reactive waste minerals is a proven method for curbing emissions from the mining sector. Carbonation technologies have also been shown to be effective at reducing potentially toxic metal mobility in alkaline mine wastes. However, the molecular scale mechanisms of metal cycling associated with mineral transformation reactions […]

An individual’s voice is unique due to a combination of their physical and social characteristics. For children who present with complex communication needs (CCN), sometimes the only functional way to communicate is by using an augmentative and alternative communication (AAC) device. AAC devices with speech output capability are known as voice output communication aids (VOCAs). […]

IHE has a variety of relevant work for MPH students with a quantiative background. In addition to work examining cost effectiveness of health interventions, IHE has ongoing work on long COVID, on the integration of infectious disease models with other domains of modelling, and other topics where the student and IHE can collaboratively define a […]

Currently, most small or medium manufacturers inspect products or parts’ visual quality manually. The manual visual quality inspection is error prone, subjective, and labor intensive. In recent years, image-based automated inspection has seen exciting uptakes in many modern factories. One critical challenge that limits their vast potentials lies in its ability to detect anomalous situations […]

With COVID and the corresponding shutdowns required of our customer base, our company, and the manufacturing industry as a whole, has become increasingly disconnected. As a result, our stagnant account list has grown substantially. We currently have 1000’s of accounts that were once viable customers that haven’t done business with our company for over a […]

A novel high temperature and high pressure materials test system, a so-called in-situ punch shear test cell, has been developed to qualify materials for reliable service in harsh environments representative of those typically encountered in oil and gas operations. Conventionally, materials are first exposed in harsh environments, then removed from the aging fluids for mechanical […]
