Abstract: A vehicle includes a vehicle battery; a vehicle sensor configured to detect a current, a voltage and a temperature of the vehicle battery; and an alternator configured to output a target voltage to the vehicle battery. A controller is configured to calculate state of charge (SOC) estimation based on the current, voltage and temperature of the vehicle battery, calculate an initial SOC based on a direct current internal resistance (DCIR) map and apply the initial SOC to the SOC estimation, when an open circuit voltage (OCV) is maintained in a predetermined range after engine-off, and adjust an available SOC range based on a difference between an actual battery charge current amount, to which the initial SOC is applied, and the calculated SOC estimation.

Abstract: Disclosed is a quenching circuit including an avalanche photodiode and a quenching diode applying a bias voltage to the avalanche photodiode. Since the quenching circuit includes the quenching diode instead of a quenching resistor, the avalanche photodiode can quickly recover to linear mode from Geiger mode, and the bias voltage applied to the avalanche photodiode is stably maintained even though a current level of the avalanche photodiode fluctuates according to the intensity of incident light.

Abstract: There are provided green-emitting quantum dots (QDs) including I-III-VI type ternary Cu—Ga—S core QDs and ZnS multishell wherein Cu:Ga is 1:10 to 1:1, and a fabricating method thereof. Integration of these QDs and red-emitting QDs into a blue LED leads to the fabrication of a white light-emitting device with high color rendering index. There are also provided blue-emitting QDs including I-III-VI type quaternary Zn—Cu—Ga—S or Cu—Ga—Al—S core QDs and ZnS multishell, and a fabricating method thereof. An electrically-driven blue light-emitting device with a QD emitting layer including these QDs interposed between a hole transport layer and an electron transport layer is fabricated.

Abstract: Provided are a data transmission system, an encoding apparatus, and a decoding method. The encoding apparatus includes an encoding unit configured to use an encoding matrix to encode original packets sequentially generated from a codec to generate an encoded packet in units of a generation. The encoding unit is configured to use information provided from the codec to dynamically determine a generation boundary of the original packets to encode the original packets. The encoding unit is configured to dynamically a generation size according to a generation time of the original packets. According to embodiments of the inventive concept, it is possible to use information provided from a VoIP codec to dynamically determine the boundary or size of a generation to decrease a standby time upon encoding/decoding, and may recover the loss of packets that may occur in a wired/wireless network.

Abstract: A thermodynamic study is performed to identify suitable refrigeration cycles for emerging application to a high-temperature superconductor (HTS) fusion system. According to recent reports on a compact and efficient fusion system, HTS magnets are supposed to operate at about 20 K by forced-flow cooling of helium gas. In addition to the main cryogenic load for the magnets, there are other cooling requirements, including the refrigeration of a thermal shield and current leads. In order to compose a closed refrigeration system without liquid-nitrogen supply or any boil-off loss, modified Brayton cycles are designed to cover the cooling loads with a circulation loop of a coolant for the magnets, the thermal shield, and the current leads. Innovative design is also proposed to integrate the cooling loop with the refrigeration cycle, as helium gas is used as a coolant and a refrigerant.
