System providing faster and more efficient data communication
A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine. The IP address of the server in the communication request is transmitted to the acceleration server, which provides a list of agents to use for this IP address. The communication request is sent to the agents. One or more of the agents respond with a list of peers that have previously seen some or all of the content which is the response to this request (after checking whether this data is still valid). The client then downloads the data from these peers in parts and in parallel, thereby speeding up the Web transfer, releasing congestion from the Web by fetching the information from multiple sources, and relieving traffic from Web servers by offloading the data transfers from them to nearby peers. |

Modeling of attacks on cyber-physical systems
Techniques of preventing sabotage attacks in cyber-physical systems involve automatically identifying links between nodes of a graph representing cyber-physical systems as vulnerable to sabotage attacks according to a vulnerability metric for each link. The vulnerability metric used depends on the particular sabotage attack used to determine the vulnerable links. Once a computer configured to design cyber-physical systems based on vulnerability to sabotage attacks receives data representing the graph, the computer enumerates the possible links between nodes of the graph along which a sabotage attack may be performed. For each of those links, the computer computes the vulnerability metric. The computer then ranks the links according to respective values of the vulnerability metric. Based on the ranking, a designer may then perform a mitigation analysis that results in changes to the graph to reduce the vulnerability at each node accessible to a malicious actor. |

A mechanism for declarative service domain federation uses a declarative approach to both the visibility aspect and the management aspect of service domain federation.

A device for protecting a direct current source and method are provided. Electric energy outputted from the direct current source is stored and an enable signal is received by the hiccup drive circuit.

Method for preparing lithium iron phosphate nanopowder
The present invention relates to a method for preparing a lithium iron phosphate nanopowder, including the steps of (a) preparing a mixture solution by adding a lithium precursor, an iron precursor and a phosphorus precursor in a glycerol solvent, and (b) putting the mixture solution into a reactor and heating to prepare the lithium iron phosphate nanopowder under pressure conditions of 10 bar to 100 bar, and a lithium iron phosphate nanopowder prepared by the method. When compared to a common hydrothermal synthesis method and a supercritical hydrothermal synthesis method, a reaction may be performed under a relatively lower pressure. When compared to a common glycothermal synthesis method, a lithium iron phosphate nanopowder having effectively controlled particle size and particle size distribution may be easily prepared. |
