Tedori-Callinan Lecture: “Isogeometric Analysis”

The vision of Isogeometric Analysis was first presented in a paper published October 1, 2005 [1].  Since then it has become a focus of research within both the fields of Finite Element Analysis (FEA) and Computer Aided Design (CAD) and is rapidly becoming a mainstream analysis methodology and a new paradigm for geometric design [2].  […]

MEAM Seminar: “Robot Design Concepts for Intuitive Physical Human-robot Interaction”

Physical human-robot interaction (pHRI) aims at taking advantage of the complementary capabilities of robots and humans. One of the key challenges in pHRI is to provide a high-bandwidth human-robot interaction that is safe and intuitive for the human user. To this end, it is proposed in this work to revisit the design of robots in […]

MEAM Seminar: “Engineering Microdevices Using Atomic Layer Deposition and Electrowetting”

This talk will cover 1) devices created one atomic layer at a time and 2) electrowetting optical elements. Atomic layer deposition (ALD) and Atomic Layer Etching (ALE) are self-limiting processes that enable accurate atomic-scale thickness control either through deposition or etching of various materials. We are developing novel manufacturing processes that study how ALD materials […]

MEAM Seminar: “Dynamical Systems Approach to Geophysical and Aerospace Flows”

A dynamical systems approach is taken to explain the dynamics of two classes of ‘gap-leaping’ geophysical flow as well as the hypersonic second-mode instability. First, in the context of a loop current system, it is shown that multiple steady flow patterns with hysteresis exist and appear to satisfy a cusp catastrophe geometry of solutions. Which […]

MEAM/LRSM Seminar: “Enabling Soft, Flexible 2D Materials and Sensors”

Low temperature synthesis of high quality 2D materials directly on flexible substrates remains a fundamental limitation towards realization of robust, strainable electronics possessing the unique physical properties of atomically thin structures. Here, we describe room temperature synthesis of uniform, stoichiometric amorphous MoS2, WSe2, and other transition metal dichalcogenides and subsequent large area (>5 cm2) photonic […]

MEAM Seminar: “Small, Autonomous, Flying Robots that can Feel and Map their Environment”

Autonomous flight through unknown environments in the presence of obstacles is a challenging problem for micro aerial vehicles (MAVs). A majority of the current state-of-art research focuses on modeling obstacles as opaque objects that can be easily sensed by optical sensors such as cameras or LiDARs. Since obstacles may not always be opaque, particularly in […]

MEAM Seminar: “Nano-compatible Neuromorphic Computers: An All-passive Approach to Neural Networks”

This era of the internet of things is poised to experience explosive growth in the number of interconnected smart electronic devices. Machine learning algorithms, such as neural networks, are expected to play an indispensable role in analyzing the data gathered by these devices, and in many cases, will also facilitate informed device responses. However, the […]

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 […]
