Modeling Air Quality and Climate Interactions: from Urban to Global Scale
Wed, Apr 15, 2009 @ 02:00 PM - 03:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker:Dr. Yang Zhang,
North Carolina State University, Raleigh, NCAbstract:Simulating air quality-climate interactions represents a major challenge in quantifying the impacts of urban/regional air pollution on climate change. A unified global-through-urban fully-coupled online climate and chemistry model provides an excellent model framework to accurately simulate such interactions. Such a unified global-through-urban model is being developed at North Carolina State University based on the U.S. NCAR's Global Weather Research and Forecasting (WRF) Model and the U.S. NOAA's mesoscale WRF with Chemistry (referred to as GU-WRF/Chem). This presentation will highlight our recent model development toward GU-WRF/Chem, demonstrate the model's capability with several case studies on urban/regional/global scales, and discuss major challenges and future directions in modeling air quality and climate/meteorology feedbacks.

Processing of bulk nanocrystalline oxide materials for optical and magnetic applications
Wed, Apr 15, 2009 @ 03:30 PM - 04:30 PM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Javier E. GarayDepartment of Mechanical EngineeringMaterials Science and Engineering ProgramUniversity of California, RiversideNanocrystalline materials display significantly different properties and behaviors than their microcrystalline counterparts, yet their direct application in products has been hindered by the difficulty in producing them reliably and efficiently. One reason is that consolidation of nanocrystalline powders usually results in large grain size increase and therefore loss of enhanced nanocrystalline properties. Recently, the versatile material processing technique of spark plasma sintering (SPS) has proven effective in overcoming the grain growth challenge—it is now possible to efficiently produce viable nanocrystalline parts. The method draws its effectiveness from large electric current densities that serve to heat the materials and also alter the processing kinetics. After an overview of our processing techniques, I will present results on large-sized, fully dense oxides with grain sizes much less that 100 nm. The materials have very different properties than traditional materials. Properties presented include improved visible light transmittance, enhanced toughness, and ferri-antiferromagnetic coupling leading to exchange bias. The results will be discussed in terms of crystal length scale effects and proximity of nanoscale phases.

CS Colloq: Lingxiao Jiang
Wed, Apr 15, 2009 @ 04:00 PM - 05:30 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Time: 4 PM - 5:30 PMLocation: GFS 223Talk Title: Scalable Detection of Similar Code: Techniques and Applications
Speaker: Lingxiao Jiang (UC Davis)
Host: Prof. Nenad MedvidovicAbstract:
Similar code, commonly known as code clones, often occur in large programs because of various software development practices, such as copying and pasting code and n-version programming. Studies show that code duplication can incur higher maintenance costs and lead to subtle errors. Identifying similar code thus has many important applications, such as program understanding, refactoring, optimization, and bug detection. In this talk, I will present three pieces of my work on techniques and applications of scalable detection of both syntactic and semantic code clones.First, I will present Deckard, a scalable and accurate tree-based code clone detection technique. The key insight is to represent syntax trees of a program as structure-preserving characteristic vectors in the Euclidean space and employ efficient hashing algorithms to cluster these vectors. Our experiments showed that Deckard scales to billions of lines of code with few false positives. Also, Deckard is language-generic, applicable to any language with a formally specified grammar.Second, we will look at a novel application of Deckard to bug detection. In particular, I will describe a general notion of
context-based inconsistencies as strong indicators of clone-related bugs and the application of Deckard to identify such inconsistencies. Many previously unknown bugs in large projects such as the Linux kernel and Eclipse were discovered. These bugs exhibit diverse characteristics and are difficult to detect with any single previous bug detection technique.Third, I will describe EqMiner, the first scalable technique to detect functionally equivalent code for understanding code duplication at the semantic level. Inspired by Schwartz's randomized polynomial identity testing, EqMiner uses automated random testing to quickly determine the functional equivalence of arbitrary code fragments automatically extracted from a large program. Evaluated on the Linux kernel, EqMiner discovered many functionally equivalent code fragments that are syntactically different. I will conclude this talk by discussing future opportunities and challenges related to code clone detection.Bio:
