Abstract:
A method of producing a mixed manganese ferrite catalyst, and a method of preparing 1,3-butadiene using the mixed manganese ferrite catalyst. Specifically, a method of producing a mixed manganese ferrite catalyst through a coprecipitation method which is performed at a temperature of 10˜40° C., and a method of preparing 1,3-butadiene using the mixed manganese ferrite catalyst through an oxidative dehydrogenation reaction, in which a C4 mixture containing n-butene, n-butane and other impurities is directly used as reactants without performing additional n-butane separation process or n-butene extraction. 1,3-butadiene can be prepared directly using a C4 mixture including n-butane at a high concentration as a reactant through an oxidative hydrogenation reaction without performing an additional n-butane separation process, and 1,3-butadiene, having high activity, can be also obtained in high yield for a long period of time.

Abstract:
Apparatuses and methods for detecting error events in a codeword reproduced by perpendicular magnetic recording medium (PMR. The method includes: generating cyclic redundancy check (CRC) parity bits based on a generator polynomial for a source information sequence to be recorded on PMR medium and recording a codeword in which the generated CRC parity bits are added to the source information sequence; and reading the recorded codeword and an error event in the read codeword. It is possible to detect error events when a codeword recorded by PMR is read, using a small number of bits.
Abstract:
In an array substrate and a display apparatus, a gate line receives a gate pulse during a present 1H period and a data line receives a pixel voltage having a polarity inverted at every frame. When a thin film transistor is turned on in response to the gate pulse during the present 1H period, a pixel electrode receives the pixel voltage through the thin film transistor during the present 1H period. A pre-charging part pre-charges the pixel electrode to a common voltage that is a reference voltage of the pixel voltage in response to a previous gate pulse during a previous 1H period.
Abstract:
Disclosed herein is an absorber with a hole for a metallic magnetic cryogenic detector and an aligning method. More specifically, the present invention is to provide an absorber with a small hole as an aligning mark for a temperature sensor used in a metallic magnetic cryogenic detector. A temperature sensor is bonded on the small hole of the absorber punched by a laser. Using the hole as an aligning mark the temperature sensor can be accurately positioned on the pick-up coil of the measuring means. Thus, the aligning method provides a magnetic measurement with an ideal coupling between the sensor and the pick-up loop. It eventually presents a precise measurement of the energy spectrum absorbed in a metallic magnetic cryogenic detector.
Abstract:
In order to set an inspection area, a measurement target is disposed onto a stage, a reference data of the measurement target is summoned, and a measurement data of the measurement target is acquired. Then, at least one feature object is selected in the measurement data and the reference data of the measurement target, and at least one feature variable for the selected feature object is extracted from each of the reference data and the measurement data. Thereafter, a change amount of the measurement target is produced by using the feature variable and a quantified conversion formula, and the produced change amount is compensated for to set an inspection area. Thus, the distortion of the measurement target is compensated for to correctly set an inspection area.
Abstract:
Disclosed are a method of controlling packet service setup and a mobile communication system. The method includes the steps of: transmitting a packet service request message containing a requested QoS to a packet service node by a mobile communication terminal; transmitting to the mobile communication terminal a packet service request response message including an assigned QoS determined in consideration of the requested QoS and network resources contained in the message received by the packet service node; comparing one or more parameter values among parameters contained in the assigned QoS contained in the packet service request response message from a mobile communication network with corresponding one or more parameter values among parameters contained in the QoS requested by the mobile communication terminal; and transmitting a packet service cancel request message if a difference between the parameter values is greater than or equal to a preset value.
