| 20080292522 | Method for Synthesizing Electrode Material Using Polyol Process - Disclosed herein is an electrode material obtained using a polyol process and a synthesis method thereof. The synthesis method includes the steps of preparing a mixed solution by mixing a transition metal compound, a polyacid anionic compound and a lithium compound with a polyol solvent; and obtaining a resultant product by reacting the mixed solution in a heating apparatus. In conventional methods of synthesizing an electrode material, such as the sol-gel method and the solid reaction method, the electrode material is synthesized through a heat treatment process, which is a post-process. However, in the method of synthesizing an electrode material according to the present invention, there is an advantage in that the electrode material, which has crystallinity due to a structure such as an olivine structure or a nasicon structure, can be synthesized using a polyol process at a low temperature without performing a heat treatment process, which is a post-process. Moreover, there are advantages in that the nanoelectrode material synthesized by the method according to the present invention has a high crystallinity, uniform particles, and a structure having a diameter ranging from several nanometers to several micrometers. Further, according to the present invention, the electrode material has a high electrochemical stability such that the discharge capacity of the electrode material is not greatly decreased even though the initial discharge capacity thereof is high and it is charged and discharged many times. | 11-27-2008 |

| 20110313817 | KEY PERFORMANCE INDICATOR WEIGHTING - The relative priorities or weightings of key performance indicators (KPIs) are objectively evaluated for a web service to facilitate determining where efforts should be made in improving the web service. A KPI-taming cost and user engagement variation is determined for each KPI. The KPI-taming cost for a KPI represents a number of engineering man-hours estimated to be required to achieve a unit of KPI improvement for that KPI. The predicted user engagement variation for a KPI represents an improvement in user engagement with the web service estimated to be provided by a certain improvement in that KPI. A KPI-sensitivity is determined for each KPI based on the KPI-taming cost and predicted user engagement variation for each KPI. A weighting may also be determined for each KPI based on the percentage of each KPI's KPI-sensitivity of the sum of KPI-sensitivities for all KPIs. | 12-22-2011 |
