DEN@Viterbi Faculty Forums are intended for faculty to meet and share their experiences with their colleagues on various instructional technologies used in their classes.
Introduction to the Division of Engineering Education
Established in 2007, USC Viterbi School's Division of Engineering Education addresses various issues surrounding engineering education that impact all departments of the school. The organization is comprised of jointly-appointed faculty from across the School, who focus a significant part of their academic activities on engineering education at the undergraduate, master's, and doctoral levels. (http://viterbi.usc.edu/academics/dee/)
DEN Instructional Video Portal
The ability to post and share media with students in a secure fashion for faculty has at USC has had its limitations. Faculty can upload their own videos on Blackboard, or use free hosting services, such as YouTube or Vimeo. However, there are some limitations with these services.
DEN@Viterbiââ¬â¢s new Kaltura Management Console hosting solution is a central content repository for uploading, editing, publishing, and tracking media securely. Jairo Delgado will go over the software, include some best practices, and provide a couple of demonstrations.
Pencasting to enhance course lectures
Pencasting is an instructional tool in which users incorporate LiveScribe Pen technology to capture and record what they are writing on a notepad, along with audio. This handwriting and accompanying synchronized audio can be played back. Electrical Engineering Professor Krishna Nayak will go over his experiences with using the LiveScribe Pen in his courses.

Talk Title: Energy-Efficient Wideband Spectrum Sensing and Modulation Classification
Abstract: Motivated by the spectrum scarcity problem, Cognitive Radios (CRs) have been proposed as a way to opportunistically allocate unused spectrum licensed to Primary Users (PUs). In this context, Secondary Users (SUs) sense the spectrum to detect the presence or absence of PUs, and use the unoccupied bands while maintaining a predefined probability of misdetection. Further, modulation classification, the process of identifying the modulation class employed by the transmitter, helps identify who is occupying a given frequency band and distinguish PUs from other users and interference. Sensing wideband channels increases the chance of finding unoccupied spectrum, and therefore increases the throughput of the CR network. The narrow-band approach for wideband spectrum sensing involves sensing multiple narrow-band channels either simultaneously, or in parallel. Both solutions either require additional receiver chains, or incur additional delays in the sensing results. Therefore, sensing wideband channels in an energy-efficient manner is highly desirable. However, wideband spectrum sensing unfolds many challenges that have not been considered in the past. In this work, we aim at answering the following fundamental question: What are the limitations of wideband spectrum sensing and modulation classification, and what are the methods to overcome them? We propose low-complexity algorithms for both cyclostationary spectrum sensing and modulation classification. Further, as a result of wideband sampling, high-rate and high-resolution ADCs become hard to design and are power hungry. As a solution to that, we propose a method to perform cyclostationary spectrum sensing using compressive sensing measurements. Moreover, given that the sampling rate of the sensing radio cannot be adapted to all signals being sensed, we study the impact of sampling clock offsets and imperfect estimates of transmit parameters on cyclostationary features. This comprehensive system level study is vital to the robust and energy-efficient design of wideband spectrum sensing and modulation classification engines for CRs.

Talk Title: Control of Multi-Vehicle Systems
Abstract: In this talk, a number of control designs for controlling multi-vehicle systems will be presented. These control designs highly depend on the type of vehicles which are controlled such as differential drives, cars, helicopters or quadrotors. They also depend on the information that is available to vehicles and vehiclesââ¬â¢ objectives to be accomplished as well as various uncertainties including perturbations and delays. In addition to some simulation results a number of experimental results including autonomous and semi-autonomous (that is, teleoperated) ground vehicles (conducted in Mechatronics and Robotics Laboratories at the University of Illinois) and aerial vehicles (in collaboration with the Boeing Company) will be presented.

Talk Title: Sentiment and Sarcasm in the 2012 US Presidential Election
Series: Natural Language Seminar
Abstract: Abstract: Political discourse is challenging from a sentiment analysis point of view because political issues are subjective and highly dynamic. Political language may contain neologisms that do not occur frequently in general purpose lexical sentiment models. Also, the presence of humor, sarcasm, and comparatives may introduce errors in sentiment analysis. In Twitter, these issues are amplified by the use of Twitter-specific features and constrained message lengths. In this presentation, we will present a collaborative project between the University of Southern California (USC) Signal Analysis and Interpretation Laboratory, USC Annenberg Innovation Laboratory, and IBM. Our system is relies on manual curation of keywords and hashtags, crowd-sourced annotation, statistical machine learned sentiment models, and a real-time visualization that is ideal for display during live events. We describe our corpus and several experiments using different settings of our sentiment models. Among our findings are that sentiment in politics is skewed towards negative, annotation agreement tend to be low, and that sarcasm is a factor that explains some of the annotator disagreement.

Talk Title: source Apportionment: Making the Most of Environmental Time - Series
Abstract: Source apportionment techniques, most notably receptor modeling and related data visualization methods, provide an often unique description of the relative contributions of different pollutant sources. At the most fundamental level they answer the question of ââ¬ËWhat emission impacts are we having on our environment?ââ¬â¢ However, in some of the most sensitive areas, e.g. in sites near large facilities such as metal works, airports and ports, and at busy roadsides where emissions are not always easily managed, they have the potential to be one of the most effective feedbacks for informing, evaluating and shaping mitigation programs.
Here, examples are presented from both previously published studies and on-going work that demonstrate the use of source apportionment as an integrated component of air quality management activities. These include:
• The use of data visualization techniques to enhance preliminary source characterization work.
• The integration of different data sources (e.g. multiple site air quality data and single site air quality and meteorological data) to provide better resolved source descriptions.
• The application of single time-series (peak) and multiple time-series (feature) isolation methods for the quantification of individual pollution events.
• The use of receptor modeling information as an input for pollution event prediction systems, providing early warnings for bad pollution days.
