The multi-constrained path (MCP) selection problem occurs when the quality-of-services (QoS) are supported for point-topoint connections in the distributed multimedia applications deployed on the Internet. This NP-complete problem is concerned about how to determine a feasible path between two given end-points, so that a set of QoS path constraints can be(More)
This paper presents the design of a third-order continuous-time (CT) single-bit active-RC sigma-delta (ΣΔ) modulator for Bluetooth application. Through the use of the architecture, cascade of resonators with distributed feedback (CRFB), the signal bandwidth can be improved without increasing the order of the modulator. All integrators are(More)

In this paper, we study the problem concerning how to construct a delay-constrained multicast tree with minimum power-consumption so that real-time multimedia applications can be supported in ad hoc wireless networks. Based on a number of link-replacing strategies, we present a heuristic called ELR algorithm for determining a multicast tree for the problem.(More)
An underfill encapsulant was used to fill the gap between the chip and the substrate around the solder joints to improve the long-term reliability of a flip-chip interconnecting system. The underfill encapsulant was filled by the capillary flow. As a part of the series studies of understanding and analysis of the underfill mechanism, this study was devoted(More)
Consider a video library system on campus, there are usually many classes demanding on the same and/or different educational video programs provided by the video server at the beginning of a session. A near video on demand system with multicast communication technology would be a proper implementation for this video library system. As a multicast stream(More)
In this paper, we are interested in an optimization problem whose goal is to construct an interference-free and delay-constrained multicast tree with maximized serviced mesh clients in multi-channel multi-radio wireless mesh networks. Based on a cross-layer design paradigm, we propose a cross-layer and load-oriented (CLLO) algorithm which can consider(More)
Multicasting is an important communication mechanism for implementing real-time multimedia applications, which usually require the underlying network to provide a number of quality-of-service (QoS) guarantees to users. In this paper, we study the problem concerning how to find a feasible multicast tree in which all the multicast paths satisfy the given set(More)
Given a video/audio streaming system installed on a multichannel multiradio wireless mesh network, we are interested in a problem concerning about how to construct a delay-constrained multicast tree to support concurrent interference-free transmissions so that the number of serviced mesh clients is maximized. In this paper, we propose a heuristic approach(More)
In this paper, we focus on the problem concerning how to construct a delay-constrained multicast tree with minimum-energy consumption in ad-hoc wireless networks. Based on link-replacing strategies, an algorithm called Energy-based Link Replacement (ELR) is presented. The ELR algorithm begins with a two-level multicast tree and then iteratively replaces the(More)
