This paper presents a DiffServ based adaptive QoS model for real-time interactive traffic in constrained bandwidth IP network without over provisioning the users. A WRR based QoS scheduling algorithm has been implemented to allocate the network resources to the users. A tuning parameter for VBR real-time traffic is also introduced in order to provide fair performance to the non real-time traffic as...
Real-time controllers handle safety-critical environments such as power grids in a continuous way. Controllers are only updated during the same maintenance periods as the plant they control. As a consequence, old software versions are usually used longer than necessary, which can have a negative impact on performance, reliability, or security. This paper presents a solution for updating component-based...
In this paper, we propose a pedestrian analysis solution helpful for adaptive content delivery and interest measurement for outdoor advertisement displays. The proposed system has built-in camera on the top panel of such displays which capture the real time viewers' frames. The captured frames have been analyzed for detection of faces using Viola-Jones algorithm. The detected faces have been processed...
In this paper, a stereo framework for a robust real time localization of objects using networkpsilas camera pairs is presented. The stereo system contains a combination of static and pan-tilt-zoom (PTZ) cameras instead of traditional dual head mounted cameras. The proposed novelty consists in applying stereo vision to heterogeneous cameras belonging to a video-surveillance network. First, a look-up-table...
In this paper we discuss a novel multihop transport scheme for wireless sensor and actor networks (WSAN) that facilitates (a) reliable multihop data packet transmission from the sensor nodes to a centralized controller (sink), and (b) reliable multihop control packet transmission from the sink to different actor nodes. The transport scheme works on a model of prioritized packet store-and-forward mechanism...
The interaction between multicasting and real-time multimedia streams poses various new and interesting problems in research on communication protocols and architectures. For example, display systems of heterogeneous users in the same session may have different or even varying latency, display resolution, and/or processing capabilities. In this paper, we propose a receiver-oriented resource reservation...
A real-time reflection/transmission imaging system is demonstrated using a 50-mW, 4.3-THz quantum cascade laser source in a closed-cycle cryorefrigerator, with a 240times320 pixel microbolometer detector. A signal-to-noise ratio of 340 is achieved with a 20-frame/sec acquisition rate.
We describe a comprehensive strategy to develop inexpensive, rugged and portable optical imaging systems for molecular imaging of cancer, which couples the development of optically active contrast agents with advances in functional genomics of cancer.
