Water vapor condensation is a familiar phenomenon in everyday life and is routinely used in industry as an effective means of transferring heat. In typical industrial systems, condensed water forms a thin liquid film due to the high surface energy associated with many industrial materials. If condensation occurs on a ...

ELECTRIC-FIELD-ENHANCED JUMPING-DROPLET CONDENSATION

  • Enright R.
  • Miljkovic N.
  • Preston D.
  • Wang E.

When condensed droplets coalesce on a superhydrophobic nanostructured surface, the resulting droplet can jump due to the conversion of excess surface energy into kinetic energy. This phenomenon has been shown to enhance condensation heat transfer by up to 30% compared to state-of-the-art dropwise condensing surfaces. However, after the droplets jump ...

Optimal Multipath Congestion Control and Request Forwarding in Information-Centric Networks: Protocol Design and Experimentation

  • Carofiglio G.
  • Gallo M.
  • Muscariello L.

The evolution of the Internet into a distributed Information access system calls for a paradigm shift to enable an evolvable future network architecture. Information-Centric Networking (ICN) proposals rethink the communication model around named data, in contrast with the host-centric transport view of TCP/IP. Information retrieval is natively pull-based, driven by ...

Battling Googost, the Bandwidth-Stealing Bot

  • Mcnamee K.

Service providers build their businesses around their networks. Eliminating bandwidth-stealing bots such as Googost and NotCompatible , a similar web proxy bot that infects Android™ phones, is key to keeping network performance and customer satisfaction high.

Sensetale ADEP as scalable realtime M2M architecture for  ITS applications

  • Dobbelaere P.

Application architectures for verticals, and ITS in particular, need to satisfy a number of often conflictory requirements. The total latency due to devices, network and computing needs to be deterministic and guaranteed to be below an application specific threshold ( O(ms) ). Application functionality is typically distributed over several devices, ...

Context-Aware Radio Access - Smarter Networks for 5G

  • Kuehn E.
  • Malanchini I.

5G network optimization will be driven by the user-centric paradigm. Users have different demands on the radio network depending on where they are, which device they use, and which service they currently need. The network should adapt to user requirements rather than forcing the user to adapt to the network.
