Abstract: An air conditioning device for a vehicle includes: a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the inflow space; a blowing unit disposed at the inflow space of the housing and configured to blow air; a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air; and an opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports. The air conditioning device adjusts the temperature of conditioned air for respective modes and reduces a flow resistance of air.

Abstract: A method of manufacturing a stacked structure includes forming a first metal buffer layer including crystal grains on a base substrate, forming a second metal buffer material layer on the first metal buffer layer, and crystallizing the second metal buffer material layer to form a second metal buffer layer, wherein the second metal buffer material layer includes crystal grains, and a density of the crystal grains of the second metal buffer material layer is lower than a density of the crystal grains of the first metal buffer layer.

Abstract: A method of detecting a thin line by an image forming apparatus includes selecting a candidate region of the thin line from image data; splitting the candidate region into a plurality of detail regions; determining a shape of the thin line by comparing pixel values of the plurality of detail regions; and detecting the thin line having the determined shape from the image data.

Abstract: In a network emulation system of the present invention, a packet transmitted from a user-mode application program is intercepted at a kernel-mode network driver and transferred to a user-mode emulation module to perform emulation, and, thereafter, the corresponding packet is returned to the network driver. The emulation module emulates a network characteristic of a multi-node environment through configuration of virtual network topology. At this time, the emulation module classifies the intercepted packets for each flow, stores the classified packets in a plurality of real queues, stores a virtual packet corresponding to the real packet in a virtual queue, and transfers the virtual packet to a virtual network including a plurality of virtual nodes to emulate the network.

Abstract: A method for modeling network traffic includes: collecting traffic of data transmitted from a network; extracting a traffic density value based on any one of the data size, the packet size, and the IDT of the collected traffic and obtaining the probability density distribution on the raw domain; separating the data into the major dataset that is a group of data having the density value of the threshold value or more and the minor dataset that is a group of data having the data density value less than the threshold value; transforming the major dataset separated on the raw domain onto the major dataset domain formed to exclude a period corresponding to the data density value of a threshold value or less; and obtaining a major dataset analysis model by applying a graph fitting algorithm on the major dataset on the major dataset domain.

Abstract: Disclosed is a scheduling method. The scheduling method includes assigning a priority associated with a transmitted order with respect to object packets based on a delayed time remaining until the object packets are reproduced, recognizing a significance of the object packets, the significance being associated with an effect on a decoding process, and scheduling the object packets based on whether the priority is assigned to the object packets and the recognized significance. The scheduling method may perform scheduling based on the delayed time and significance, thereby effectively providing multimedia services and a data communication server.
