Abstract: Provided is an opportunistic forwarding method and apparatus for a content-based information centric network in a delay tolerant network environment. The opportunistic forwarding method for a content-based information centric network in a delay tolerant network environment having a processor and a memory includes when a first node contacts a second node, updating a first delivery predictability and a second delivery predictability of the first node based on contact record information between the first node and the second node and data that the second node has, updating a first message of the first node by comparing the first message including first interest information and first data that the first node has with a second message including second interest information and second data that the second node has, and delivering the first message of the first node to the second node based on the first and second delivery predictabilities of the first node.

Abstract: A system for dynamically replicating data for a heterogeneous Hadoop is provided. The system includes a name node having a replication manager. The replication manager calculates a probability that a map task is allocated to a map task slot of a data node that stores an input data block of the map task out of a plurality of map task slots of data nodes by using a number of the map task slots in the Hadoop clusters comprised of heterogeneous clusters, and dynamically replicates data based on the probability.

Abstract: A visco-poroelastic elastomer-based capacitor type tactile sensor includes a first electrode, an active layer formed on a top surface of the first electrode and made of a visco-poroelastic elastomer, a second electrode formed on a top surface of the active layer, and a controller configured to provide an electric field generated orthogonal to an extension direction of the first electrode and the second electrode between the first electrode and the second electrode. In proportion to an external pressure applied to the tactile sensor, a concentration of effective ions present at the interfaces between the active layer and the first and second electrodes is increased.

Abstract: A method for an energy-aware selective compression scheme (EASCS) for solar-powered wireless sensor networks is provided. The method includes calculating an amount of residual energy of a battery in each of sensor nodes in a wireless sensor network, selecting one operation mode between a compression mode and a latency mode in reply to the amount of the residual energy, wherein the compression mode is a mode that data is compressed and transmitted, and the latency mode is a mode that the data is transmitted without compression, and compressing and transmitting the data if the compression mode in the each of the sensor nodes is selected, or transmitting the data without compression if the latency mode in the each of the sensor nodes is selected.Accordingly, end-to-end latencies of sensor networks can be reduced while blackout times thereof do not increase by implementing energy optimization in the wireless sensor network.

Abstract: An apparatus for an electrochemical discharge machining process is provided. The apparatus includes a holder housing having, an inlet hole, an outlet hole, a first side, and a second side, and containing an electrolyte, a tool holder disposed at the first side, and a first electrode having a first end and a second end. The holder housing is configured to sealingly accommodate the electrolyte unless at least one of the inlet hole and the outlet hole is open. The first end is coupled to the tool holder and the second end passes through the second side. Since the apparatus is moved to a machining position of the work-piece by a worker, additional power for controlling the position thereof is not necessary. In addition, the apparatus is easy to carry and use because of its simple structure.
