Background modeling is the key technology for moving target detection implemented with the background difference method. The conventional background modeling methods cost large amount of calculation time, in order to improve the speed and precision of the model, this paper presents an improved Frame Difference Background Modeling. The frame difference background modeling was initialized by Sele...

This article investigates the secure control problem for cyber-physical systems when malicious data are injected into cyber realm, which directly connects to actuators. Based on moving target defense (MTD) and reinforcement learning, we propose a novel proactive reactive scheme. First, system <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlin...

We present an application of a multi hypothesis tracking (MHT) algorithm to the case of ground moving targets detected by GMTI (Ground Moving Target Indicator) radar sensors. The algorithms for track extraction, prediction, filtering, and track maintenance are briefly described, and exemplary tracking results for simulated MTI data are demonstrated.

Abstract: Multiple targets tracking with a GMTI is a challenging problem for the battlefield surveillance. A new algorithm is used in order to track multiple manoeuvring ground targets with road constraint. However, the case of nondetected targets due to the ground context is not tacking in account in the target tracking process. In this paper, we present our approach to track ground targets wi...

The communication environment within organizations provides multiple opportunities for informational retrieval throughout the day. While previous research has explored media choice from a sender’s perspective, little research has explored the choices receivers or targets make in attending to messages and information streams. This paper explores the process that targets use to evaluate messages ...

In this paper we consider the detection of a moving point target using Along-Track (AT) InSAR systems. We consider two cases: conventionally and one bit coded raw data. The performance of the system is evaluated by comparing the probabilities of false alarm and detection.

This publication is a follow-up study to MTI publication 00-01, Why Campaigns for Local Transportation Funding Initiatives Succeed or Fail: An Analysis of Four Communities and National Data. The earlier publication was case studies of four local ballot tax measures for transportation packages. The current study, Factors Influencing Voting Results of Local Transportation Funding Initiatives with...

Introduction: Use of patient-based voice assessment scales is an appropriate method that is frequently used to demonstrate effectiveness of voice therapy. This study was aimed at determining the effectiveness ofvoice therapy among patients with secondary muscle tension dysphonia (MTD) and vocal mass lesions.   Materials and Methods: The study design was prospective, with within-participant repe...

This chapter presents the design and initial simulation results for a prototype moving-target defense (MTD) system, whose goal is to significantly increase the difficulty of attacks on enterprise networks. Most networks are static, which gives attacker’s a great advantage. Services are run on well-known ports at fixed, easily identifiable IP addresses. The goal of an MTD system is to eliminate ...
