MEAM Seminar: “Delivering Expressive and Personalized Fingertip Haptic Cues”

The importance of meaningful tactile experiences has become increasingly apparent in areas such as teleoperation, education, and gaming. As the applications of rendering haptic stimuli are growing, so are the requirements of haptic interfaces, in that the intended audience is becoming more diverse and the intended interactions are becoming more complicated. For the past few […]

MEAM Doctoral Dissertation Defense: “Additive Manufacturing and Mechanical Properties of Cellulose Nanofibril Materials”

Cellulose nanofibrils (CNFs) are a nanomaterial derived from plants that have high specific stiffness and strength, can be made into optically transparent materials, and are biodegradable. These properties make CNFs an attractive building block for bulk structural materials. However, CNFs are typically produced in aqueous suspension at low CNF weight fractions (<1 wt.%), which makes […]

MEAM Seminar: “Mechanical Models for DNA”

We will discuss two complementary mechanical models for DNA that deal with, respectively two problems: one, phase transitions in a DNA molecule, and two, allosteric interactions between two ligands bound to DNA. Experimental studies on single molecules of DNA have reported a rich variety of cooperative structural transitions, including coexistence of three phases, when a […]

MEAM Seminar: “From Elder Care Service Robots to the Design of Low-Cost End-Effectors and Novel Manipulation Techniques”

Older adults are forming a much larger percentage of the population leading to a strain in the healthcare sector. It is expected that the population aged 65 and over in the United States alone will double in the next 30 years, and similarly worldwide. Despite abundance of the facilities to accommodate the growing older adult […]

MEAM Seminar: “Microscale Robotic Wetware for Synthetic Biology”

Small-scale robotic systems have emerged as promising tools to perform a wide-range of tasks in microbiology and medicine such as targeted delivery, cell manipulation, environmental monitoring, and microassembly. In order to perform these tasks, the robot must execute precise locomotion, take measurements from its environment, and use those measurements to make decisions. However, unlike their […]

MEAM Seminar: “A Multi-Scale Homogenization Model for the Viscoplastic Response of Polar and Sea Ice”

The rheology of polar ice evolves in response to weather and climate changes, by modifying its microstructure. While the experimental evidence for the dependence of rheological properties on the microstructure is well documented, there are only a few modeling efforts to capture the rheological behavior of polar ice, mostly by fitting continuum models to the […]

MEAM Seminar: “Effect of Nanoparticle Size on the Mechanical Properties of Nanoparticle (NP) Assemblies”

Nanoparticle assemblies (NPAs) have attracted tremendous interests of various research communities. The particle-size-effect on mechanical properties of NPAs is systematically studied. With decreasing the particle size d from 300 nm to 10 nm, the SiO2 NPAs become drastically harder (∼39×), stiffer (∼15×), and tougher (>3.5×). The results are consistent with the data scattered in the […]

MEAM Seminar: “Thermalization of Bulk Magnetic Materials in Spin-Lattice Dynamics Simulations”

Spin-lattice dynamics (SLD), an increasingly popular simulation method which simultaneously computes both atomic displacements and spins, offer new possibilities for modeling the temporal evolution of systems where the coupling between these atomic features are relevant such as spin caloritronics, heat assisted magnetic recording, magnetocaloric responses and magnetic nanoparticle hyperthermia. To accurately model and understand these […]

MEAM Seminar: “Machine Learning for Robotics: Achieving Safety, Performance and Reliability by Combining Models and Data in a Closed-Loop System Architecture”

The ultimate promise of robotics is to design devices that can physically interact with the world. To date, robots have been primarily deployed in highly structured and predictable environments. However, we envision the next generation of robots (ranging from self-driving and -flying vehicles to robot assistants) to operate in unpredictable and generally unknown environments alongside […]

MEAM Seminar: “Hierarchical Task-Parameterized Learning from Demonstration “

Many modern humanoid robots are designed to operate in human environments, like homes and hospitals. Such robots could help humans accomplish tasks and lower their physical and/or mental workload. However, robot users in homes and hospitals typically are not familiar with robotics or programming, therefore it is difficult for them to adapt robots to their […]
