The collage method for inverse problems has become well-established in the literature in recent years. Initial work developed a collage theorem, based upon Banach’s fixed point theorem, for treating inverse problems for ordinary differential equations (ODEs). Amongst the subsequent work was a generalized collage theorem, based upon the Lax-Milgram...

Pollution-induced illnesses are caused by toxicants that result from human activity and should be entirely preventable. However, social pressures and misperceptions can undermine the efforts to limit pollution, and vulnerable populations can remain exposed for decades. We present a human-environment system model for the effects of water pollution o...

We present a theoretical framework to solve inverse problems for systems of delayed ordinary differential equations (delay ODEs) that allows us to estimate the values of unknown parameters, such as coefficients and time delays, using available time series data. This work builds on similar results for non-delayed ODEs, inspired by the Collage Theore...

Pollution-induced illnesses are caused by toxicants that result from human activity and are often entirely preventable. However, where industrial priorities have undermined responsible governance, exposed populations must reduce their exposure by resorting to voluntary protective measures and demanding emissions abatement. This paper presents a cou...
