Abstract:
The method for constructing precast coping for bridge enables for a segment to be match-cast manufactured at the top of a pier body. The method may be applied to small and medium size bridges by introducing transverse tendon force to each segment through tendons after manufacturing a subsegment which is match cast manufactured using sides of a pre-made segment as molding. Further, the method for constructing precast coping for bridge enables to construct precast coping for bridge by easily lifting the coping, which is assembled on the ground, using lifting lugs that are formed on the top of manufacturing segments.
Abstract:
An electric generating system using a solar cell improves the quality of output power by including a converter for converting an output voltage generated from the solar cell into a DC voltage in a pulse shape. An inverter converts the DC voltage in the pulse shape into an AC voltage and applies the AC voltage to a power system and a control device for determining whether an erroneous operation of the electric generating system using the solar cell is generated or not based on an output voltage of the solar cell, an output current of the solar cell and a voltage of the power system. At least one inverter switching device among a plurality of inverter switching devices performs a switching at a frequency higher than a frequency during a normal operation at an interval where the erroneous operation is generated.

Abstract:
Disclosed are a method of forming metal wiring and metal wiring formed using the same. The method includes printing wiring using an ink composition including metallic nanoparticles and dispersants maintaining dispersion of the metallic nanoparticles, performing a first firing process of firing the wiring under vacuum or in an inert atmosphere to suppress grain growth, and performing a second firing process of firing the wiring with the vacuum or inert atmosphere released, to accelerate grain growth. The method of forming metal wiring induces abnormal grain growth by rapidly removing dispersants, capable of inducing the growth of metallic nanoparticles, at a temperature at which the growth force of the metallic nanoparticles is high, in the process of firing the metallic nanoparticles. Accordingly, the metal wiring has a coarse-grained structure containing metallic particles with a large average particle size, and the electrical and mechanical characteristics thereof can be enhanced.
Abstract:
The present invention relates to a method for recommending other users who have similar preference with a user. The method includes the steps of: acquiring information on objects selected by a user and other users; acquiring information on topics; determining to which topic the user and the other users respectively correspond; evaluating a degree of user similarity by each other user, the degree of user similarity being relevant to sum of probabilities of the specific object appearing in the state of a topic while k-th other user and the user have the topic as a probability of the k-th other user and the user having selected the specific object, by referring to correspondence relationships; and recommending specific other users who have a high degree of user similarity, wherein the degree of user similarity is evaluated by multiplying the sum by a probability of the specific object appearing independently.
Abstract:
There are provided a method and an apparatus for generating a current command value for tracking the maximum power point of a solar energy generating system. The apparatus includes: a voltage detector detecting a voltage input into the flyback power converter; a first calculator calculating an output power from the detected input voltage; a second calculator calculating a power variation based on the calculated output power and a voltage variation of the input voltage; and a current command value generator generating a current command value for tracking the maximum power point of the solar cell module from the calculated voltage variation and the calculated power variation. Accordingly, a current command value after calculating an output power may be generated with only a voltage detector, without a current detector, thereby reducing the costs of a solar energy generating system by decreasing the costs for a high-priced current detector, and simplifying circuit.
