Vegetation greenness, detected using digital photography, is useful for monitoring phenology of plant growth, carbon uptake and water loss at the ecosystem level. Assessing ecosystem phenology by greenness is especially useful in spatially extensive, water‐limited ecosystems such as the grasslands of the western United States, where productivity is...

Fostering an effective learning environment in large classes is a challenge: instructors and teaching assistants are stretched thin across many students, students often lack opportunities for personal interaction with course staff, and the size of the classes makes them seem impersonal. Furthermore, students in large classes can often find solution...

In this paper we study the simultaneous problems of food waste and hunger in the context of food (waste) rescue and redistribution as a means for mitigating hunger. To this end, we develop an empirical model that can be used in Monte Carlo simulations to study the dynamics of the underlying problem. Our model's parameters are derived from a data se...

We present an agent-based model of bicycle racing that incorporates both physiology and the types of multiplayer scenarios that arise in real races. In these scenarios, riders can choose to share the workload with other riders (cooperate) or pursue their own self-interests (defect). We compare the model's predictions to race situations and use it t...

In this paper we study the simultaneous problems of food waste and hunger in the context of the possible solution of food (waste) rescue and redistribution. To this end, we develop an empirical model that can be used in Monte Carlo simulations to study the dynamics of the underlying problem. Our model's parameters are derived from a unique data set...

Plants can have positive effects on each other in numerous ways, including protection from harsh environmental conditions. This phenomenon, known as facilitation, occurs in water-stressed environments when shade from larger shrubs protects smaller annuals from harsh sun, enabling them to exist on scarce water. The topic of this paper is a model of...

In arid and semi-arid regions, landscaping can reduce the energy use of a home and generate a more pleasing environment for the home's residents. However, water in these regions is a scarce resource, which makes landscaping a tradeoff between conflicting objectives--maximizing the growth on the landscape while minimizing the water use. This paper p...

A species classifier is presented which decides whether or not short groups of clicks are produced by one or more individuals from the following species: Blainville's beaked whales, short-finned pilot whales, and Risso's dolphins. The system locates individual clicks using the Teager energy operator and then constructs feature vectors for these cli...
