    scc: Cluster Storage Provisioning Informed by Application Characteristics and SLAs

    Storage for cluster applications is typically provisioned based on rough, qualitative characterizations of applications. Moreover, configurations are often selected based on rules of thumb and are usually homogeneous across a deployment; to handle increased load, the application is simply scaled out across additional machines and storage of the same type....

    Distributed Wide Area Scene Analysis in Reconfigurable Camera Networks

    Over the past decade, large-scale camera networks have become increasingly prevalent in a wide range of applications, like security and surveillance, disaster response and environmental modeling. In many applications, constraints of bandwidth, security concerns, and difficulty in storing and analyzing huge amounts data centrally at a single location necessitate the...

    Rico: A Security Proxy for Mobile Code

    Security technology suitable for the burgeoning embedded system market has not been widespread. Untrusted code downloaded from the Internet poses numerous security risks due to the possible presence of viruses or other malicious entities. System administrators typically administer one or more administrative domains making policy management for mobile code a...

    Supporting Mobile Device Communications in the Presence of Broadcast Servers

    Broadcast data dissemination is well-suited for mobile wireless environments, where bandwidth is scarce, and mutual interference must be minimized. However, broadcasting monopolizes the medium, precluding clients from performing any other communication. This paper addresses this problem in two ways. First, the authors segment the server broadcast, with intervening periods of...

    Pointwise-Dense Region Queries in Spatio-Temporal Databases

    Applications such as traffic management and resource scheduling for location-based services commonly need to identify regions with high concentrations of moving objects. Such queries are called dense region queries in spatiotemporal databases, and desire regions in which the density of moving objects exceeds a given threshold. Current methods for addressing...

    Massively Parallel XML Twig Filtering Using Dynamic Programming on FPGAs

    In recent years, XML-based Publish-Subscribe Systems have become popular due to the increased demand of timely event-notification. Users (Or subscribers) pose complex profiles on the structure and content of the published messages. If a profile matches the message, the message is forwarded to the interested subscriber. As the amount of...

    Extrinsic Camera Calibration Using Multiple Reflections

    This paper presents a method for determining the six-Degree-of-Freedom (DOF) transformation between a camera and a base frame of interest, while concurrently estimating the 3D base-frame coordinates of unknown point features in the scene. The camera observes the reflections of fiducial points, whose base-frame coordinates, are known, and reconstruction points,...

    Persistent Observation of Dynamic Scenes in an Active Camera Network

    This paper deals with the problem of persistent observation of a wide area scene through decentralized, cooperative control of an active camera network. This paper focuses on applications where events unfold over a large geographic area and need to be analyzed by multiple cameras. There is no central unit accumulating...

    Studying Software Evolution for Taming Software Complexity

    Reducing software complexity is key to reducing software maintenance costs. To discover complexity-reducing practices, this paper studies the evolution of seven sizable open source programs over a long period of time. The authors first measure how software complexity changes as programs evolve, and identify complexity-reducing releases. The authors then study...

    QoS-Aware Object Replica Placement in CDN Networks

    Recently, Content Distribution Networks (CDNs) have attracted a great deal of attention from both the industry and academic communities. This paper design efficient object replication algorithms to achieve the optimal performance while not violating clients QoS requirements. The authors show that such a problem is NP-complete and solve it with...

    Towards Self-Managing QoS-Enabled Peer-to-Peer Systems

    Peer-to-peer systems that dynamically interact collaborate and share resources are increasingly being deployed in wide-area environments. The inherent ad-hoc nature of these systems makes it difficult to meet the Quality of Service (QoS) requirements of the distributed applications, thus having a direct impact on their scalability, efficiency arid performance. This...

    A Framework for Joint Network Coding and Transmission Rate Control in Wireless Networks

    Network coding has been proposed as a technique that can potentially increase the transport capacity of a wireless network via processing and mixing of data packets at intermediate routers. However, most previous studies either assume a fixed transmission rate or do not consider the impact of using diverse rates on...

    Food Subsides, Growth And Poverty A Critique On Neoliberal Institutional Structure

    The relationship among payment style of subsidies, economic growth and poverty is a matter of challenge among economists and policy makers. Neoliberal Institutional Structure in framework of what is called "Washington Consensus" and "Structural adjustment policies and economic stabilization" argues on economic advantages of removing food general subsidies so necessity...

    A High-Level Synthesis Flow for Custom Instruction Set Extensions for Application-Specific Processors

    Custom Instruction Set Extensions (ISEs) are added to an extensible base processor to provide application-specific functionality at a low cost. As only one ISE executes at a time, resources can be shared. This paper presents a new high-level synthesis flow targeting ISEs. This paper emphasizes a new technique for resource...

    Accelerating XML Query Matching Through Custom Stack Generation on FPGAs

    Publish-subscribe systems present the state of the art in information dissemination to multiple users. Such systems have evolved from simple topic-based to the current XML-enabled systems. Here, users pose complex queries expressed in XPath on the structure and content of the streaming documents. The parts of the documents that match...

    Distributed Multi-Target Tracking in a Self-Configuring Camera Network

    This paper deals with the problem of tracking multiple targets in a distributed network of self-configuring pan-tilt zoom cameras. This paper focuses on applications where events unfold over a large geographic area and need to be analyzed by multiple overlapping and non-overlapping active cameras without a central unit accumulating and...

    Boosting XML Filtering With a Scalable FPGA-Based Architecture

    The growing amount of XML encoded data exchanged over the Internet increases the importance of XML based publish-subscribe (pub-sub) and content based routing systems. The input in such systems typically consists of a stream of XML documents and a set of user subscriptions expressed as XML queries. The pub-sub system...

    Autocannibalistic and Anyspace Indexing Algorithms With Applications to Sensor Data Mining

    Efficient indexing is at the heart of many data mining algorithms. A simple and extremely effective algorithm for indexing under any metric space was introduced in 1991 by Orchard. Orchard's algorithm has not received much attention in the data mining and database community because of a fatal flaw; it requires...

    Mirror-Based Extrinsic Camera Calibration

    This paper presents a method for determining the six degrees-of-freedom transformation between a camera and a base frame of interest. A planar mirror is maneuvered so as to allow the camera to observe the environment from several viewing angles. Points, whose coordinates in the base frame are known, are observed...
