Progress of integrated circuit technology allows integration of analog and digital circuits on the same chip. This co-integration yields higher performances and reliability, while reducing power consumption, but also raises new challenges for circuit designers. The substrate noise generated by the switching digital part has detrimental effects on the analog part. In this contribution, a wide-ba...

In this paper, we address the relative navigation problem of a chaser circumnavigating a target. The chaser has an on-board camera and observes a set of features on the target; the goal is to obtain a detailed map of the landmarks. By controlling the yaw-rotation of the sensor it is possible to maximize the time allocated to landmark observation. An Extended Kalman Filter (EKF) provides state u...

The purpose of this paper focuses on designing an intelligent, compact, reliable, and robust auxiliary vacuum brake system (VBS) with Kalman filter and self-diagnosis scheme. All of the circuit elements in the designed system are integrated into one programmable system-on-chip (PSoC) with entire computational algorithms implemented by software. In this system, three main goals are achieved: (a)...

Though the importance of curvature continuity on compressor blade performances has been realized, there are two major questions that need to be solved, i.e., the respective effects of curvature continuity at the leading-edge blend point and the main surface, and the contradiction between the traditional theory and experimental observations in the effect of those novel leading-edge shapes with s...

----------------------------------------------------------------ABSTRACT----------------------------------------------------A promising approach for processors and processor-based systems (e.g., systems on a chip, or SoCs) corresponds to the so-called software-based self-test (SBST) the basic idea is to generate test programs to be executed by the processor and able to fully exercise the proces...

Recently, OpenCL, a new open programming standard for GPGPU programming, has become available in addition to CUDA. OpenCL can support various compute devices due to its higher abstraction programming framework. Since there is a semantic gap between OpenCL and compute devices, the OpenCL C compiler plays important roles to exploit the potential of compute devices and therefore its capability sho...

This dissertation describes our efforts to improve sensor network performance evaluation and portability, within the context of the sensor network project Hogthrob. In Hogthrob, we faced the challenge of building a sensor network architecture for sowmonitoring. This application has hard requirements on price and performance, and shows great potential for using sensor networks. Throughout the pr...

Video shot boundary detection is the basic step in the area of content based video analysis and retrieval. Various automatic shot boundary detection techniques have been proposed and their performances are reliable, especially for video cut detection. However most of the proposed methods are sensitive to camera, object motion and lighting changes. In this paper, we have focused mainly on the im...
