  • Yu, Albert (2013)
    <p>There has been an unprecedented growth in both the amount of data and the number of users interested in different types of data. Users often want to keep track of the data that match their interests over a period of ...
  • Albert, Michael Joseph (2013)
    <p>Cremer and McLean 1985 shows that if buyers valuations are suciently correlated, there is a mechanism that allows the seller to extract the full surplus from the buyers. However, in practice, we do not see the Cremer-McLean ...
  • Liu, Yang (2011)
    <p>Rapid data growth nowadays makes it more critical to reduce search time to improve the performance of search-intensive applications. However, huge data size makes it more difficult to efficiently perform search operations. ...
  • Bhattacharya, Sayan (2012)
    <p>We design algorithms for markets consisting of multiple items, and agents with budget constraints on the maximum amount of money they can afford to spend. This problem can be considered under two broad frameworks. (a) ...
  • Herodotou, Herodotos (2012)
    <p>Modern industrial, government, and academic organizations are collecting massive amounts of data ("Big Data") at an unprecedented scale and pace. The ability to perform timely and cost-effective analytical processing ...
  • Shakimov, Amre (2012)
    <p>Online Social Network (OSN) services such as Facebook and Google+ are fun and useful. Hundreds of millions of users rely on these services and third-party applications to process and share personal data such as friends ...
  • Manweiler, Justin Gregory (2012)
    <p>In our homes and in the enterprise, in our leisure and in our professions, mobile computing is no longer merely "exciting;" it is becoming an essential, ubiquitous tool of the modern world. New and innovative mobile ...
  • Letchford, Joshua (2013)
    <p>Game theory involves the study of how self-interested agents interact in various settings. Perhaps the best-known game theoretic solution concept is that of Nash equilibrium. However, Nash equilibrium makes a number ...
  • Guo, Mingyu (2010)
    <p>In many multiagent settings, a decision must be made based on the preferences of multiple agents, and agents may lie about their preferences if this is to their benefit. In mechanism design, the goal is to design ...
  • Xia, Lirong (2011)
    <p>For at least two thousand years, voting has been used as one of the most effective ways to aggregate people's ordinal preferences. In the last 50 years, the rapid development of Computer Science has revolutionize every ...
  • Guevara, Marisabel Alejandra (2014)
    <p>Heterogeneous design presents an opportunity to improve energy efficiency but raises a challenge in management. Whereas prior work separates the two, we coordinate heterogeneous design and management. We present a ...
  • Slee, Sam (2010)
    <p>The power of modern computer systems is due in no small part to their fantastic ability to adapt to whatever tasks they are charged with. Self-reconfigurable robots seek to provide that flexibility in hardware by building ...
  • Hu, Jun (2014)
    <p>This work centers on digital stack photography and its applications.</p><p>A stack of images refer, in a broader sense, to an ensemble of</p><p>associated images taken with variation in one or more than one various ...
  • Sahu, Sudheer (2007-12-10)
    We study the following fundamental questions in DNA based self-assembly and nanorobotics: How to control errors in self-assembly? How to construct complex nanoscale objects in simpler ways? How to transport nanoscale ...
  • Bao, Xuan (2013)
    <p>The inclusion of rich sensors on modern smartphones has changed mobile phones from simple communication devices to powerful human-centric sensing platforms. Similar trends are influencing other personal gadgets such as ...
  • Gopalkrishnan, Nikhil (2012)
    <p>Self-assembly is a pervasive natural phenomenon that gives rise to complex structures and functions. It describes processes in which a disordered system of components form organized structures as a consequence of specific, ...
  • Liu, Dongtao (2013)
    <p>Sleek and powerful touchscreen devices with continuous access to high-bandwidth wireless data networks have transformed mobile into a first-class development platform. Many applications (i.e., "apps") written for these ...
  • Cuervo, Eduardo (2012)
    <p>Advances in mobile hardware and operating systems have made mobile a first-class development platform. Activities such as web browsing, casual game play, media playback, and document reading are now as common on mobile ...
  • Gu, Zhiqiang (2012)
    <p>In computer vision, the pictorial structure model represents an object in an image by parts that are arranged in a deformable configuration. Each part describes an object's local photometric appearance, and the configuration ...
