    • Multifractal Properties of TCP Traffic: a Numerical Study 

      Riedi, Rudolf H.; Vehel, Jacques (1997-10-20)
      We analyze two traces of TCP--traffic recorded at the gateway of a LAN corre­ sponding to two hours at Berkeley and to eight hours at CNET labs respectively. We are mainly interested in a multifractal approach, which we ...

      Dai, Zhaohe; Weng, Chuanxin; Liu, Luqi; Hou, Yuan; Zhao, Xuanliang; Kuang, Jun; Shi, Jidong; Wei, Yuenguang; Lou, Jun; Zhang, Zhong (2016)
      In this study, we report the polymer-based graphene foams through combination of bottom-up assembly and simple triaxially buckled structure design. The resulting polymer-based graphene foams not only effectively transfer ...
    • MultiHop Communication is Order Optimal for Homogeneous Sensor Networks 

      Chakrabarti, Arnab; Sabharwal, Ashutosh; Aazhang, Behnaam (2004-04-01)
      The main goal of this paper is to show that multi-hop single-user communication achieves the per node transport capacity of O(lnN/N) in homogeneous sensor networks, making it order-optimal. Our contributions in this paper ...
    • Multilayer three-dimensional filter paper constructs for the culture and analysis of aortic valvular interstitial cells 

      Sapp, Matthew C.; Fares, Hannelle J.; Estrada, Ana C.; Grande-Allen, K. Jane (2015)
      Culturing aortic valvular interstitial cells in an environment that models the aortic valve is an essential step towards understanding the progression of calcific aortic valve disease. Here the adaption of a three-dimensional ...
    • A multilayered scaffold of a chitosan and gelatin hydrogel supported by a PCL core for cardiac tissue engineering 

      Pok, Seokwon; Myers, Jackson D.; Madihally, Sundararajan V.; Jacot, Jeffrey G. (2013)
      A three-dimensional scaffold composed of self-assembled polycaprolactone (PCL) sandwiched in a gelatin–chitosan hydrogel was developed for use as a biodegradable patch with a potential for surgical reconstruction of ...
    • Multilevel Codes and Iterative Multistage Decoding: Rate Design Rules and Practical Considerations 

      Borran, Mohammad Jaber; Aazhang, Behnaam (2000-09-20)
      It is well known that MultiLevel Coding (MLC) and MultiStage Decoding (MSD) suffice to approach capacity if the rates at different levels are chosen appropriately. In most of the practical cases, however, the rate design ...

      Cakareski, Zeljko; Ahmed, Nasir; Dhar, Aditya; Aazhang, Behnaam (2002-05-20)
      This paper addresses the problem of broadcasting video over wireless channels. In such a scenario, different end users perceive the video signal through channels with different quality. We propose a source-channel coding ...
