Aerospace and Mechanical Engineering Candidate Series
Mon, Feb 29, 2016 @ 10:00 AM - 11:00 AM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Jenni Sidey, Research Assistant, Department of Engineering at the University of Cambridge
Talk Title: Experimental and numerical investigations of flames with gas turbine applications at the University of Cambridge
Abstract: With growing concern over anthropogenic climate change and increasingly stringent emission standards, the development of low-emission combustion technologies is a necessity. This seminar is concerned with the motivation, development, and implementation challenges associated with gas turbine and reciprocating engine pollutant reduction and the tools the combustion community is using to meet them. Of particular interest is the investigation of processes in which hot combustion products are used as a diluent for fresh reactants. The underlying physics of these processes will be discussed with results from laminar flame calculations, droplet autoignition simulations, and fundamental turbulent flame investigations with high speed laser diagnostics, while their application potential will be assessed through the investigation of a novel gas turbine combustor concept.
Biography: Jenni Sidey is a research associate at the University of Cambridge. Her postdoctoral position, funded by the European Commission Joint Clean Sky Initiative, focuses on the investigation of non-premixed, premixed, and spray flame extinction and thermoacoustic oscillations in gas turbine combustors. She completed her PhD in the summer of 2015, investigating heavily preheated and diluted flames. While studying Mechanical Engineering at McGill University, she took part in alternative fuel production and microgravity flame propagation experiments.

Talk Title: Interactive Machine Learning for Information Extraction
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
Most of the world's knowledge, be it factual news, scholarly research, social communication, subjective opinions, or even fictional content, is now easily accessible as digitized text. Unfortunately, due to the unstructured nature of text, much of the useful content in these documents is hidden. The goal of "information extraction" is to address this problem: extracting meaningful, structured knowledge (such as graphs and databases) from text collections. The biggest challenges when using machine learning for information extraction include the high cost of obtaining annotated data and lack of guidance on how to fix mistakes.
In this talk, I propose interpretable representations that allow users and machine learning models to interact with each other: enabling users to inject domain knowledge into machine learning, and providing explanations for why a machine learning model is making a specific prediction. I study these techniques using relation extraction as the application, an important subtask of information extraction where the goal is to identify the types of relations between entities that are expressed in text. I first describe how symbolic domain knowledge, if provided by the user as first-order logic statements, can be injected into relational embeddings to improve the predictions. In the second part of the talk, I present an approach to "explain" any machine learning prediction using a symbolic representation, which the user may annotate directly for more effective supervision. I present experiments that demonstrate that an interactive interface between a user and machine learning is effective in reducing annotation effort and in quickly training accurate extraction systems.
Biography: Sameer Singh is a Postdoctoral Research Associate at the University of Washington, working on large-scale and interactive machine learning applied to information extraction and natural language processing. He received his PhD from the University of Massachusetts, Amherst, during which he also interned at Microsoft Research, Google Research, and Yahoo! Labs on massive-scale machine learning. He was recently selected as a DARPA Riser, won the grand prize in the Yelp dataset challenge, has been awarded the Yahoo! Key Scientific Challenges and the UMass Graduate School fellowships, and was a finalist for the Facebook PhD fellowship.

Spatial Light Interference Microscopy (SLIM) for Quantitative Biomedicine
Mon, Feb 29, 2016 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Prof. Gabriel Popescu, Department of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign
Talk Title: Spatial Light Interference Microscopy (SLIM) for Quantitative Biomedicine
Series: Medical Imaging Seminar Series
Abstract: Most living cells do not absorb or scatter light significantly, i.e. they are essentially transparent, or phase objects. Phase contrast microscopy proposed by Zernike in the 1930s represents a major advance in intrinsic contrast imaging, as it reveals inner details of transparent structures without staining or tagging. While phase contrast is sensitive to minute optical path-length changes in the cell, down to the nanoscale, the information retrieved is only qualitative. Quantifying cell-induced shifts in the optical path-lengths permits nanometer scale measurements of structures and motions in a non-contact, non-invasive manner. Thus, quantitative phase imaging (QPI) has recently become an active field of study and various experimental approaches have been proposed.
Recently, we have developed Spatial Light Interference microscopy (SLIM) as a highly sensitive QPI method. Due to its nanometer pathlength sensitivity, SLIM enables interesting structure and dynamics studies over broad spatial (nanometers-centimeters) and temporal (milliseconds-weeks) scales. I will review our recent results on applying SLIM to basic cell studies, such as intracellular transport, cell growth, and single cell tomography. Recently, we have demonstrated that SLIM is a valuable tool for cancer diagnosis and prognosis in unlabeled biopsies. This capability is particularly valuable in prostate pathology.

Talk Title: Advanced Electronic Materials for Next-Generation Biomedical Implants and Bio tools
Abstract: Innovating electronic materials and related process technologies are critical in building next generation large scale, bio-electronic interface for biomedical implants and bio-tools.
In this talk, the influence of materials and process innovation will be discussed in the context of achieving two essential properties at the bio-electronic interface, bio conformality and bio stability. First, to reconcile the mechanic properties mismatch between soft, curvilinear organ surface and conventional rigid, planar electronics, Si nanomembrane enables bio conformal electronics from top down approach and advanced micro/nano fabrication on flexible substrates. In the second part of the talk, I will discuss how to achieve long term bio-stability at the bio-electronic interface through an ultrathin hermetic thermal silicon dioxide layer from a special device fabrication process. A capacitively coupled, bio-conformal sensing electronics with over 1,000 channels demonstrate the robustness of this encapsulation strategy. Together, these results form a realistic pathway towards bio compatible, bio conformal and bio stable electronic implants, with potential for broad utility, such as brain/heart activity mapping, brain-machine interface, and pharmaceutical screening. At the end of my talk, I will show how we can leverage recent advancements in nano electronics into building next generation bio electronics and solve big problems in biology, especially in brain activity mapping.
