    Improving Region SelectionThrough Early-Exit Detection

    Many Dynamic Binary Translation (DBT) systems and just-in-time compilers target traces, i.e., frequently-taken execution paths, as code regions to be translated/optimized. The Next-Tail-Execution (NET) trace selection method used in HP Dynamo is an early example of such techniques. Many current trace optimization schemes are actually variations of NET. These NET-like...

    A Dynamic Binary Translation System in a Client/Server Environment

    With rapid advances in mobile computing, multi-core processors and expanded memory resources are being made available in new mobile devices. This trend will enable a wider range of existing applications to be migrated to mobile devices, for example, running desktop applications in IA-32 (x86) binaries on ARM-based mobile devices transparently...

    Cyber-Physical Elements of Disaster Prepared Smart Environment

    Recent years have ushered in tremendous advances in Information and Communication Technologies (ICT) and infrastructures for disaster management. Still, daily news on disasters has been telling one that even people in technologically advanced regions remain ill prepared. Smart and intelligent environments now offer one an increasingly broader spectrum of devices...

    Compressive Image Sensing: Turbo Fast Recovery With Lower-Frequency Measurement Sampling

    Fast and accurate compressive sensing recovery is still a challenging issue, and has received considerable attention in the literature. In this paper, the authors do not follow the tradition of imposing certain sparsity patterns on a CS recovery algorithm. On the contrary, they propose to design a new and novel...

    SQLMR : A Scalable Database Management System for Cloud Computing

    As the size of data set in cloud increases rapidly, how to process large amount of data efficiently has become a critical issue. MapReduce provides a framework for large data processing and is shown to be scalable and fault-tolerant on commondity machines. However, it has higher learning curve than SQL-like...

    Workflow Architecture for Model-Based Development of User-Centric Automation and Assistive Devices

    This paper describes an on-going effort in building user-centric automation and assistive devices from workflows. Advantages of this approach include that workflow-based devices and systems are naturally componentized and easily configurable. Models of a new device, user actions and users defined in terms of activities and workflows are executable. The...

    The Design and Evaluation of Task Assignment Algorithms for GWAP-Based Geospatial Tagging Systems

    Geospatial tagging (geotagging) is an emerging and very promising application that can help users find a wide variety of location-specific information, and thereby facilitate the development of advanced location-based services. Conventional geotagging systems share some limitations, such as the use of a two-phase operating model and the tendency to tag...

    An Analytical Study of GWAP-Based Geospatial Tagging Systems

    Geospatial tagging (geo-tagging) is an emerging and very promising application that can help users find a wide variety of location-specific information, and facilitate the development of future location-based services. Conventional geo-tagging systems share some limitations, such as the use of a two-phase operating model and the tendency to tag popular...

    Power-Rate-Distortion Optimized Resource-Scalable Low-Complexity Video Coding in Wireless Multimedia Sensor Networks

    Wireless Multimedia Sensor Networks (WMSNs) have been potentially applicable for several emerging applications. However, the available resources, i.e., power and rate, of visual sensors in a WMSN are very limited. Hence, it is important but challenging to achieve efficient resource allocation and optimal video compression while maximizing the overall network...

    Tree Decomposition for Large-Scale SVM Problems: Experimental and Theoretical Results

    To handle problems created by large data sets, the authors propose a method that uses a decision tree to decompose a data space and trains SVMs on the decomposed regions. Although there are other means of decomposing a data space, they show that the decision tree has several merits for...

    An Evaluation of Routing Reliability in Non-Collaborative Opportunistic Networks

    An opportunistic network is a type of challenged network that has attracted a great deal of attention in recent years. While a number of schemes have been proposed to facilitate data dissemination in opportunistic networks, there is an implicit assumption that each participating peer behaves collaboratively. Consequently, these schemes may...

    Playing GWAP With Strategies

    Human Computation represents a new paradigm of applications that exploit people's desire to be entertained by outsourcing certain steps of the computational process to the players. Such applications also produce useful metadata as a by-product. Games With A Purpose (GWAP) demonstrate the potential of human computation to solve a variety...

    An Evaluation Study of Mobility Support in ZigBee Networks

    Based on the IEEE 802.15.4 LR-WPAN specification, the ZigBee standard has been proposed to interconnect simple, low rate, and battery powered wire-less devices. The deployment of ZigBee networks is expected to facilitate numerous applications, such as home healthcare, medical monitoring, consumer electronics, and environmental sensors. For many of the envisioned...
