| 20080241040 | Nano-scale metal halide scintillation materials and methods for making same - Crystalline scintillator materials comprising nano-scale particles of metal halides are provided. The nano-scale particles are less than 100 nm in size. Methods are provided for preparing the particles. In these methods, ionic liquids are used in place of water to allow precipitation of the final product. In one method, the metal precursors and halide salts are dissolved in separate ionic liquids to form solutions, which are then combined to form the nano-crystalline end product. In the other methods, micro-emulsions are formed using ionic liquids to control particle size. | 10-02-2008 |

| 20100026650 | METHOD AND SYSTEM FOR EMPHASIZING OBJECTS - Method and system for emphasizing objects is disclosed. The method includes receiving input characters from a user of the electronic device and predicting one or more characters based on the input characters. Moreover, the method includes calculating a distance of each predicted character from a last input character. The method also includes calculating an emphasizing priority of each predicted character based on priority of each predicted character and the distance of each predicted character from the last input character. The method further includes emphasizing the predicted characters based on the emphasizing priority of the predicted characters. | 02-04-2010 |
| 20100299447 | Data Replication - A method, system and computer program product for managing data replication for data groups stored in a first storage device. A polling interval, a maximum bandwidth and a bandwidth tolerance available for data replication is defined. A priority and a status for each data group is defined. The data replication is started in the polling interval, for the data group with highest priority in the pending status to a second storage device connected to the first storage. The rate of data transfer during a polling period is determined by dividing the total data transferred during the polling interval by time period of the polling interval; and bandwidth utilization is determined for data replication by comparing rate of data transfer with maximum bandwidth. If the bandwidth utilization is less than the maximum bandwidth available then another data group is selected for replication. If the data bandwidth utilization is more than the maximum bandwidth available then selected data groups replicating are paused. | 11-25-2010 |

| 20080281938 | Selecting a master node in a multi-node computer system - Selecting a master node in a multi-node computer system is described. Each node of the multi-node computer system selects a timeout value (e.g., randomly). Each node starts a timer, which is set to expire at the selected timeout value of its corresponding node. The node with the timer that expires earliest broadcasts an election message to the other nodes of the multi-node computer system, which informs the other nodes that the broadcasting node is a candidate for mastership over the multi-node computer system. The other nodes respond to the election message upon receiving it. In the absence of a refusal message from one or more of the other nodes, the candidate is established as master node in the multi-node computer system and wherein the other nodes function as slave nodes therein. | 11-13-2008 |
| 20090217282 | PREDICTING CPU AVAILABILITY FOR SHORT TO MEDIUM TIME FRAMES ON TIME SHARED SYSTEMS - A computer implemented CPU utilization prediction technique is provided. CPU utilization prediction is implemented described in continuous time as an auto-regressive process of the first order. The technique used the inherent autocorrelation between successive CPU measurements. A specific auto-regression equation for predicting CPU utilization is provided. CPU utilization prediction is used in a computer cluster environment. In an implementation, CPU utilization percentage values are used by a scheduler service to manage workload or the distribution of requests over a vast number of CPUs. | 08-27-2009 |
| 20100103781 | TIME SYNCHRONIZATION IN CLUSTER SYSTEMS - Techniques are described herein for synchronizing cluster time. According to one technique, a master node is appointed in a cluster. Other “slave” nodes periodically synchronize their clocks with the master node. To synchronize its clock with the master node, a slave node sends a timestamped message to the master node, which also timestamps the message and sends the message back to the slave node, which then timestamps the message again. Based on the timestamps, the slave node is able to determine the difference between the master node's clock's time and slave node's clock's time, compensating for the message travel time between master node and slave node. Depending on various circumstances, and based on the determined difference, the slave node adjusts its clock so that the time indicated by the slave node's clock at least begins to approach more closely the time indicated by the master node's clock. | 04-29-2010 |
