Abstract: Group interactions are prevalent in various complex systems (e.g., collaborations of researchers and group discussions on online Q&A sites), and they are commonly modeled mas hypergraphs. Hyperedges, which compose a hypergraph, are non-empty subsets of any number of nodes, and thus each hyperedge naturally represents a group interaction among entities. The higher-order nature of hypergraphs brings about unique structural properties that have not been considered in ordinary pairwise graphs.

Abstract: Buildings account for 40% of carbon emissions globally, which can be attributed to (i) fossil energy use primarily for heating and cooling, and (ii) to the embodied carbon in conventional construction materials such as concrete and steel. Recent efforts have focused on making buildings green by integrating renewable energy generation, but the intermittency of these sources necessitates the use of thermal energy storage (TES) to match demand and supply.

Abstract: Process monitoring is essential for process repeatability and qualification, and for AM components can serve to help qualify the final parts themselves. For powder blown laser DED, mass flow is a crucial parameter whose measurement has proven to be particularly difficult, often with large errors. Similarly, current research approaches for defect detection in AM parts using optical, thermal, and acoustic monitoring have shown promise, but tend to be limited to qualitative assessments rather than quantitative ones.

Abstract: Many additive parts need machining in order to be functional. It may be that machining is required to meet dimensional tolerances or to meet surface finish requirements for mating or sealing surfaces, for example. It may be that the part contains features that are difficult to print such as threaded holes or holes with high aspect ratios. These parts may be made in hybrid machine tools (additive and subtractive in the same workspace) or they may be made by hybrid processes (separate additive and subtractive machines).

IRIM hosts each semester a symposium to feature presentations from faculty and presentations of research that has been funded by our IRIM seed grant program in the last year.

The symposium is a chance for faculty to meet new PhD students on campus, as well as a chance to get a better idea of what IRIM colleagues are up to these days. The goal of the symposium is to spark new ideas, new collaborations, and even new friends!

This course module is designed for individuals interested in hands-on training in the fabrication of microfluidic devices using the soft lithography technique. It is structured to assume no prior knowledge of the technologies by the participants. The course agenda is evenly divided between hands-on laboratory sessions, including SU-8 master mold creation using photolithography and PDMS device fabrication in  the IEN cleanroom, and supporting lectures.
