Abstract: A filament type nano-sized lone fiber and a method of producing the same are disclosed. In the method, a spinning solution or a spinning melt is electro-spun in drops using a spinneret to which a critical voltage is applied, and the spun drops are continuously collected on a multi-collector. The spinning solution is produced dissolving a blend or copolymer consisting of two or more kinds of polymers in a solvent. The spinning melt is produced by melting the polymers. The multi-collector is selected from the group consisting of a plate type collector, a roll type collector, and a combination thereof. The filament type nano-sized long fiber is processed into a yarn through one step during the electrospinning process, and thus, mechanical properties are better than those of conventional nanofiber non-woven fabric. Consequently, the filament type nano-sized long fiber can be utilized for the extended application.

Abstract: Disclosed is a channel estimator and a method for changing a coefficient of an IIR filter depending on a moving speed of a mobile communication terminal. In the channel estimator, a coefficient changing unit receives I and Q signals from a current base station, and selects a coefficient of the IIR filter optimized depending on the moving speed of the current mobile communication terminal. The coefficient changing unit sets the selected coefficient of the IIR filter to the IIR filter of the channel estimator. Accordingly, it is possible to prevent the performance degradation of the channel estimator caused by the speed of the mobile communication terminal.

Abstract: Disclosed is a method for producing an epoxy nanocomposite material containing vapor-grown carbon nanofibers and an epoxy nanocomposite material produced thereby. The method comprises physically mixing 0.1-5.0 parts by weight of vapor-grown carbon nanofibers as reinforcing materials with 100 parts by weight of an epoxy matrix resin to disperse the carbon nanofibers in the epoxy matrix resin, adding a curing agent to the mixture, and curing the mixture. According to the disclosed method, the vapor-grown carbon nanofibers are physically mixed with an epoxy matrix resin without using any solvent. Thus, the vapor-grown carbon nanofibers are sufficiently dispersed in the epoxy matrix resin compared to the case of using a solvent. Therefore, it is possible to produce an epoxy nanocomposite material having excellent mechanical strength and low friction/wear properties at room temperature and excellent thermal properties even at high temperature.
