    Two-Stage Compensator Designs With Partial Feedbacks

    The two-stage compensator designs of linear system are investigated in the framework of the factorization approach. First, the authors give "Full feedback" two-stage compensator design. Based on this result, various types of the two-stage compensator designs with partial feedbacks are derived. The factorization approach to control systems has the advantage...

    Instruction Folding in a Hardware-Translation Based Java Virtual Machine

    Bytecode hardware-translation improves the performance of a Java Virtual Machine (JVM) with small hardware resource and complexity overhead. Instruction folding is a technique to further improve the performance of a JVM by reducing the redundancy in its stack-based operations. However, the variable instruction length of the Java bytecode makes the...

    Simultaneous Optimization for Dynamic Sensor Function Allocation and Effective Sensed Data Aggregation in Wireless Sensor Networks

    This paper proposes a method to realize sensor function allocation and effective data aggregation simultaneously in wireless sensor networks. This method realizes dynamic allocation of sensor functions so as to balance the distribution of each sensor function in a target monitoring area. In addition, effective data aggregation is performed by...

    TinyBee: Mobile-Agent-Based Data Gathering System in Wireless Sensor Networks

    This paper proposes a mobile-agent-based data gathering system (called TinyBee) in wireless sensor networks. Most existing mobile-agent-based systems consider only static sinks/servers. In this paper, the authors consider both mobile servers and lightweight mobile agents. They aim to design a data gathering system using a special kind of mobile agent...

    Learning to Detect Spam: Naive-Euclidean Approach

    A method is proposed for learning to classify spam and non-spam emails. It combines the strategy of the Best Stepwise Feature Selection with a classifier of Euclidean nearest-neighbor. Each text email is first transformed into a vector of D-dimensional Euclidean space. Emails were divided into training and test sets in...

    Performance Analysis of Large Receive Offload in a Xen Virtualized System

    System-level virtualization provides one various advantages including independent and isolated computing environments on which multiple operating systems can be executed, and improved resource utilization. These benefits come with performance overheads and network operation is one of most typical cases. In this paper, the authors first present the experimental results of...
