This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...
Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...
Small-scale fisheries often suffer from weak, formal governance, and in response they organize in various ways. These self-organizational arrangements rely on the capacity of informal institutions, such as norms and communication, in generating social cohesion among actors in the supply chain and therefore improve the likelihood of generating commonly devised...

With growing interest in mass timber, especially mass timber panels (MTP), there has been a need to better understand their structural properties. One of the most versatile uses for MTP are as floor systems. Under new code provisions, these floors can be utilized in new and taller building types, but...
Nanoscale Instrumented Indentation Testing (IIT) is a material characterization technique that is used to determine mechanical properties. The size effects present at this scale make it difficult to expand findings to a bulk scale. Modeling can be used to bridge this gap and better understand nanoscale IIT and the size...
Multi-robot teams offer promising solutions for many long term deployments in remote and dangerous domains, such as extraterrestrial or underseas exploration. However, long term deployments present many problems preventing robot teams from operating effectively. Learning over long time scales is makes it difficult to assign credit to robots' actions, as...
Learning to recognize objects is a fundamental and essential step in human perception and understanding of the world. Accordingly, research of object discovery across diverse modalities plays a pivotal role in the context of computer vision. This field not only contributes significantly to enhancing our understanding of visual information but...
When a person is tasting wine, they first evaluate the appearance and then the aroma. The smell of wine is a crucial part of tasting and the aromas emanating from the wine should be pleasant. Aroma quality perceived in wine is determined by multiple interactions of the components found in...
Prototyping is a crucial step in product design and development, but it is also known as the highest sunk cost. The top 20 Research and Development (R&D) department spends 142 billion dollars, yet 40 to 46 percent of this money goes into developing products that cannot even make to the...
Understanding how spatial variation in climate correlates with phenotypic variation among individuals may offer insights about local adaptation, population performance, and species’ response to climate change. Desert bighorn sheep (Ovis canadensis nelsoni) in the Mojave Desert of southern California experience a broad range of temperature and aridity, inhabiting mountain ranges...
