  • Thiagarajan, Arvind; Ravindranath, Lenin; Balakrishnan, Hari; Madden, Samuel R.; Girod, Lewis D. (USENIX Association, 2011-03)
    CTrack is an energy-efficient system for trajectory mapping using raw position tracks obtained largely from cellular base station fingerprints. Trajectory mapping, which involves taking a sequence of raw position samples ...
  • Mittal, Manas; Wu, Wei; Rubin, Steve; Madden, Samuel R.; Hartmann, Björn (Association for Computing Machinery (ACM), 2012-02)
    Corruption is endemic in many emerging economies - many transactions of private citizens with government institutions require payment of bribes. While well known as a general phenomenon, specific data about the "bribe ...
  • Ravindranath, Lenin; Thiagarajan, Arvind; Balakrishnan, Hari; Madden, Samuel R. (Association for Computing Machinery (ACM), 2012-02)
    A growing class of smartphone applications are tasking applications that run continuously, process data from sensors to determine the user's context (such as location) and activity, and optionally trigger certain actions ...
  • Kaler, Timothy; Lynch, John Patrick; Peng, Timothy; Sivalingam, Lenin Ravindranth; Thiagarajan, Arvind; Balakrishnan, Hari; Madden, Samuel R. (Association for Computing Machinery, 2010-01)
    Modern smartphones are equipped with a wide variety of sensors including GPS, WiFi and cellular radios capable of positioning, accelerometers, magnetic compasses and gyroscopes, light and proximity sensors, and cameras. ...
  • Malviya, Nirmesh; Madden, Samuel R.; Bhattacharya, Arnab (International Conference on Data Engineering, 2011-04)
    In this paper, we address the problem of answering continuous route planning queries over a road network, in the presence of updates to the delay (cost) estimates of links. A simple approach to this problem would be to ...
  • Kimura, Hideaki; Huo, George; Rasin, Alexander; Madden, Samuel R.; Zdonik, Stanley B. (Association for Computing Machinery (ACM), 2010-09)
    We describe an automatic database design tool that exploits correlations between attributes when recommending materialized views (MVs) and indexes. Although there is a substantial body of related work exploring how to ...
  • Marcus, Adam; Wu, Eugene; Karger, David R.; Madden, Samuel R.; Miller, Robert C. (CIDR, 2011-01)
    Amazon's Mechanical Turk (\MTurk") service allows users to post short tasks (\HITs") that other users can receive a small amount of money for completing. Common tasks on the system include labelling a collection of ...
  • Madden, Samuel R. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    Sensor networking hardware, networking, and operating system software has matured to the point that the major challenges facing the field now have to do with storing, cleaning, and querying the data such networks produce. ...
  • Madden, Samuel R.; Harizopoulos, S.; Argyros, T.; Boncz, P. A.; Dietterich, D.; Waas, F. M. (Institute of Electrical and Electronics Engineers (IEEE), 2010-04)
    The last few years have been exciting for data management system designers. The explosion in user and enterprise data coupled with the availability of newer, cheaper, and more capable hardware have lead system designers ...
  • Cheung, Alvin K.; Thiagarajan, Arvind; Madden, Samuel R. (Association for Computing Machinery (ACM), 2011-11)
    This demo will showcase LifeJoin, a system that collects raw sensor data from phones and laptop computers to generate interesting events. Given the raw sensor data, LifeJoin implements a number of activity recognition ...
  • Marcus, Adam; Wu, Eugene; Karger, David R.; Madden, Samuel R.; Miller, Robert C. (Association for Computing Machinery (ACM), 2011-06)
    Crowdsourcing technologies such as Amazon's Mechanical Turk ("MTurk") service have exploded in popularity in recent years. These services are increasingly used for complex human-reliant data processing tasks, such as ...
  • Marcus, Adam; Wu, Eugene; Madden, Samuel R.; Miller, Robert C. (VLDB Endowment, 2011-09)
    Crowdsourcing markets like Amazon's Mechanical Turk (MTurk) make it possible to task people with small jobs, such as labeling images or looking up phone numbers, via a programmatic interface. MTurk tasks for processing ...
  • Sivalingam, Lenin Ravindranth; Newport, Calvin Charles; Balakrishnan, Hari; Madden, Samuel R. (USENIX Association, 2011-03)
    With the proliferation of mobile wireless devices such as smartphones and tablets that are used in a wide range of locations and movement conditions, it has become important for wireless protocols to adapt to different ...
  • Jones, Evan Philip Charles; Abadi, Daniel J.; Madden, Samuel R. (Association for Computing Machinery (ACM), 2010-01)
    Database partitioning is a technique for improving the performance of distributed OLTP databases, since "single partition" transactions that access data on one partition do not need coordination with other partitions. For ...
  • Wu, Eugene; Balakrishnan, Hari; Cheung, Alvin K.; Sivalingam, Lenin Ravindranth; Madden, Samuel R. (Association for Computing Machinery (ACM), 2013-07)
    Smart-phone applications ("apps") run across a wide range of environmental conditions, locations, and hardware platforms. They are often subject to an array of interactions that are hard or impossible for developers to ...
  • Wu, Eugene; Curino, Carlo; Madden, Samuel R. (CIDR Conference, 2011-01)
    One of the key tenets of database system design is making efficient use of storage and memory resources. However, existing database system implementations are actually extremely wasteful of such resources; for example, ...
  • Madden, Samuel R.; Yen, Christine Y.; Yang, Christopher M.; Tan, Ceryen C. (Institute of Electrical and Electronics Engineers, 2010-04)
    In this paper, we describe a scheme for tolerating and recovering from mid-query faults in a distributed shared nothing database. Rather than aborting and restarting queries, our system, Osprey, divides running queries ...
  • Madden, Samuel R.; Solar-Lezama, Armando; Cheung, Alvin K. (Association for Computing Machinery (ACM), 2011-09)
    Bugs in deployed software can be extremely difficult to track down. Invasive logging techniques, such as logging all non-deterministic inputs, can incur substantial runtime overheads. This paper shows how symbolic analysis ...
  • Wu, Eugene; Madden, Samuel R. (International Conference on Data Engineering, 2011-04)
    Many data-intensive websites use databases that grow much faster than the rate that users access the data. Such growing datasets lead to ever-increasing space and performance overheads for maintaining and accessing ...
  • Tu, Stephen Lyle; Kaashoek, M. Frans; Madden, Samuel R.; Zeldovich, Nickolai (Association for Computing Machinery (ACM), 2013-08)
    MONOMI is a system for securely executing analytical workloads over sensitive data on an untrusted database server. MONOMI works by encrypting the entire database and running queries over the encrypted data. MONOMI introduces ...
