Layered multicast is an e cient technique to deliver video to users over wired and wireless networks. In this paper, we consider such a multicast system in which the server adapts the bandwidth and FEC of each layer so as to maximize overall video quality, given the heterogeneous user characteristics in terms of their end-to-end bandwidth, packet drop rate over the wired network, and bit error ...
1 This work is part of EEEAG 104E163, a project sponsored by Vidiator Technology (US) Inc, TUBITAK, The Turkish National Science Foundation, and Dokuz Eylul University, Department of Computer Engineering. AbstractThis work presents Reliable Download analyses with and without interleaving in MBMS (Multimedia Broadcast Multicast Services) under various network conditions specific to MBMS. Since M...
Annex E of the Digital Video Broadcasting IPTV (DVB-IPTV) technical specification defines an optional Application-Layer Forward Error Correction (AL-FEC) protocol to protect the streaming media transported using RTP. The DVB-IPTV AL-FEC protocol uses two layers for FEC protection. The first (base) layer is based on the 1-D interleaved parity code. The second (enhancement) layer is based on the ...
High-performance optical communications require a very low bit error rate (BER) down to 10-15 with soft-decision (SD) forward correction (FEC). There are several performance metrics based on soft information for systems SD-FEC, but system budgets usually described conventional Q-factor converted from pre-FEC BER, hard decision its convenience and history. In this work, enhancing the feasibility...
For 9 consecutive months (March-November 2008), faecal samples were collected monthly from 129 horses residing within 40 km of Salzburg, Austria. Samples were analysed quantitatively using a modified McMaster egg counting technique. Whenever a faecal egg count (FEC) result exceeded 250 eggs per gram (EPG), the horse was treated with pyrantel, ivermectin or moxidectin. In 52 of 129 horses (40.3%...
The synthesis of ferroeene-ethynyl phosphine platinum dichloride complexes based on (FeC=C)"Ph3 _ nP (ta, 11 = 1; tb, 11 = 2; te, 11 = 3; Fe = ferroeenyl, (.,s-CsHs)(.,s-CsH4 )Fe) is deseribed. Air-oxidation of te afforded (FeC= ChP=O (6). Treatment of ta-tc with [(PhC= NJ,PtClz] (2) or [(tht)AuCI] (tht = tetrahydrothiophene) (7), respeetively, gave the heterometallie transition complexes cis-[...
Background The ARTemis trial previously reported that addition of neoadjuvant bevacizumab (Bev) to docetaxel (D) followed by fluorouracil, epirubicin and cyclophosphamide (D-FEC) in HER2 negative breast cancer improved the pathological complete response (pCR) rate. We present disease-free survival (DFS) and overall survival (OS) with central pathology review. Patients and methods Patients wer...
The objective of this study was to evaluate the clinical response of locally advanced breast cancer (LABC) to neoadjuvant (NA) chemotherapy with 5-fluorouracil, epirubicin and cyclophosphamide (FEC) and to study the role of docetaxel in patients who fail to respond to first-line chemotherapy. Patients were enrolled who had primary tumours without distant metastasis that were too extensive for c...
FEC is widely used to improve the quality of noisy transmission media as wireless links. This improvement is of importance for a transport protocol as TCP which uses the loss of packets as an indication of network congestion. FEC shields TCP from losses not caused by congestion but it consumes some bandwidth that could be used by TCP. We study in this paper the tradeoff between the bandwidth co...
