  • Publication number: 20140110049
    Abstract: A thermal interface material provides thermal conduction or thermal dissipation across an interface, using a three-dimensional interconnected porous graphene (3D-IPG) foam structure. The 3D-IPG foam structure is constructed of three-dimensional interconnected graphene sheets formed as a plurality of monolayers, and having an flexible interconnection architecture. The flexible interconnection architectures allow the 3D-IPG to maintain a high interfacial thermal conductance by the 3D-IPG filling a gap between a heat source and a heat sink across the interface, and by capping small features up to nanoscale roughened surfaces.

  • Publication number: 20140037379
    Abstract: A landfill soil cover system is proposed for preventing water infiltration into a landfill and gas emission from the landfill under all weather conditions. The landfill cover system comprises three soil layers; namely, a clay layer, a gravelly sand layer and a silt layer, compacted successively from the bottom to the top of the system. The clay layer is compacted immediately above an optional gas collection layer and landfill waste at an optimum water content. Additionally, a trench for water drainage may be constructed, for example, every 20-40 m in the horizontal direction. Water infiltration and landfill gas emission can be prevented effectively by this landfill soil cover system under any humid, semi-arid and arid climates.

  • Patent number: 8630222
    Abstract: The described method and system provide an efficient routing of data packets protocol in an event-driven and delay-constrained WSN (wireless sensor network) that optimizes the sleep/wake schedule of nodes to maximize the lifetime of the WSM, subject to a constraint on the source-to-sink delay. Online forwarding techniques may be used to transfer data reports from monitoring nodes to the sink. A delay-constrained and energy-efficient routing protocol (DCEER) for asynchronous WSNs may be used to maximize the lifetime of the WSN while remaining within the maximum allowable delay requirements. With DCEER, each node may maintain the historical cost of forwarding a packet from itself to the sink as its virtual coordinate, and packets are forwarded in the direction of descending coordinates. The cost-based coordinates may change dynamically with a time-varying channel or topology.
