Organic light emitting diode device

Abstract: An organic light emitting diode (OLED) device is provided The OLED device includes: a substrate; an anode formed on the substrate; a first organic thin layer formed on the anode; an organic emission layer formed on the first organic thin layer; a second organic thin layer formed on the organic emission layer; and a cathode formed on the second organic thin layer, wherein the first and second organic thin layers are formed in a single layer or a multi-layer, and at least a part of the first or second organic thin layer is doped with or formed of an insulator The OLED device provides excellent durability, long life-time, and increased luminous efficiency by balanced charge injection caused by doping or stacking the insulator into or on the organic thin layer

Negative active material for rechargeable lithium battery and rechargeable lithium battery including same

Abstract: Embodiments of the present invention are directed to negative active materials for lithium rechargeable batteries and to lithium rechargeable batteries including the negative active materials. The negative active material includes a crystalline carbon material having pores, and amorphous conductive nanoparticles in the pores, on the surface of the crystalline carbon, or both in the pores and on the surface of the crystalline carbon. The conductive nanoparticles have a FWHM of about 0.35 degrees (°) or greater at the crystal plane that produces the highest peak as measured by X-ray diffraction.

Tv graphical user interface providing selection among various lists of tv channels

Abstract: A TV graphical user interface (GUI) in a satellite TV system enables users to create customized lists of TV channels. Everyday, favorite and theme lists may be generated to respectively combine TV channels being watched regularly, favorite TV channels and channels relating to particular subjects. An oval list name object is arranged on a screen to indicate the name of the currently selected list of TV channels. The users may click on the list name object to make their selection among various TV channel lists available in the TV system. In a channel changer mode, the TV GUI displays a graphical channel changer composed of channel boxes that show numbers and logos of TV channels in the currently selected list. To switch the TV set to a required TV channel, the user clickss on the graphical channel box that indicates the required channe. In a program guide mode, a list of TV programs may be provided based on the channel changer. Vertical program bars that display TV programs are aligned with the channel boxes indicating TV channels that carry the corresponding TV programs. To identify various TV channel lists available in the TV system, the oval list name object, as well as the channel boxes and program bars, are displayed in a color that represents a selected TV channel list.

Monetary Cost-Aware Checkpointing and Migration on Amazon Cloud Spot Instances

Abstract: Recently introduced spot instances in the Amazon Elastic Compute Cloud (EC2) offer low resource costs in exchange for reduced reliability; these instances can be revoked abruptly due to price and demand fluctuations. Mechanisms and tools that deal with the cost-reliability tradeoffs under this schema are of great value for users seeking to lessen their costs while maintaining high reliability. We study how mechanisms, namely, checkpointing and migration, can be used to minimize the cost and volatility of resource provisioning. Based on the real price history of EC2 spot instances, we compare several adaptive checkpointing schemes in terms of monetary costs and improvement of job completion times. We evaluate schemes that apply predictive methods for spot prices. Furthermore, we also study how work migration can improve task completion in the midst of failures while maintaining low monetary costs. Trace-based simulations show that our schemes can reduce significantly both monetary costs and task completion times of computation on spot instance.

Method of Forming Metal Oxide and Apparatus for Performing the Same

Abstract: In a method and an apparatus for forming metal oxide on a substrate, a source gas including metal precursor flows along a surface of the substrate to form a metal precursor layer on the substrate. An oxidizing gas including ozone flows along a surface of the metal precursor layer to oxidize the metal precursor layer so that the metal oxide is formed on the substrate. A radio frequency power is applied to the oxidizing gas flowing along the surface of the metal precursor layer to accelerate a reaction between the metal precursor layer and the oxidizing gas. Acceleration of the oxidation reaction may improve electrical characteristics and uniformity of the metal oxide.
