although lot streaming scheduling is an active research field, lot streaming flexible flow lines problems have received far less attention than classical flow shops. this paper deals with scheduling jobs in lot streaming flexible flow line problems. the paper mathematically formulates the problem by a mixed integer linear programming model. this model solves small instances to optimality. moreo...

While speech recognition Word Error Rate (WER) has reached human parity for English, continuous scenarios such as voice typing and meeting transcriptions still suffer from segmentation punctuation problems, resulting irregular pausing patterns or slow speakers. Transformer sequence tagging models are effective at capturing long bi-directional context, which is crucial automatic punctuation. Aut...

The Paper presents multimedia system for accessible distant education which consists of multimedia browser accessible for visually impaired people and content distribution streaming server integrated with e-learning management system, which allow interactive online access to storage materials in DAISY 3 (ANSI/NISO Z39.86 2005 Specifications for the Digital Talking Book) format. The developed Da...

In this paper a heterogeneous network model based on the IMS-SIP (session Initiation protocol) with the help of Authentication, Authorization, and Accounting (AAA) protocol that integrates the Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) technologies is proposed to improve QoS. The proposed Loos...

Next generation carriers Internet backbone node arclutecture are proposed that offer sophisticated QoS support including real time voice, video streaming, and VPN. The backbone core node, MSN (Multi-service network) Type-X, has 320 Gb/s throughput and IP V4N6 dual stack forwarding capability and OC-192C full wire-rate forwarding performance. In addition, sophisticated DiiXServ having 4096 virtu...

T he advent of object-based multime-dia standards, in particular MPEG-4, has brought new challenges to the subject of media streaming over the Internet. To tackle these challenges, the Moving Picture Expert Group (MPEG) defined a generic multimedia delivery platform—the Delivery Multimedia Integration Framework—under the MPEG-4 umbrella. In this article we describe the DMIF framework and examin...

Telematics enhances the operations of a modern car. The Messenger on-the-drive (MOD) is developed as an inter-vehicle multi-networked voice/text communication utility, which enables the seamless wireless or telecommunications among the drivers and passengers in a fleet of cars. Two core features of Stream Control Transmission Protocol (SCTP), multi-streaming and multihoming, are applied for imp...

(Technical Report WPI-CS-TR-02-17) Proceedings of the Packet Video Workshop Nantes, France April 2003 http://www.cs.wpi.edu/~claypool/papers/h2h/ The Hungry Wolf Bandwidth Requirements for Video • Streaming media growing – 350,000 hours of online video broadcast ’01 • Voice is 32-64 Kbps, but video has range of data rates – Videoconference 0.1 Mbps (H.261, MPEG-4) – VCR 1.2 Mbps (MPEG-1) – Broa...

In today’s high-speed communication era, when a user moves from one network to another, voice call and video streaming should not be interrupted. Different wireless network technologies such as WLAN, a cellular network, WiMAX coexist and they have different data rate and different area of coverage. Therefore, it is very challengeable to design an efficient vertical handoff scheme which will sat...

New technologies such as IEEE 802.16 (Wi-MAX) [2] and IEEE 802.11e (Wi-Fi with QoS) [1] enable differentiated services. In this study we explore the potential for increasing the revenue of Internet service providers with differentiated services. For concreteness, we focus on two generic services that we call “voice” and “data.” However, the analysis applies to services that have different requi...
