Method and apparatus for a secure and deduplicated write once read many virtual disk
A method and apparatus is provided for the operation of a secure and deduplicated write once read many virtual disk which exceeds the write performance of traditional cryptographic methods.

The propagation time is determined using the transmission time information. The aim is to improve the accuracy when determining the propagation time. This is achieved in that the second network component returns the message to the first network component immediately after the message is encountered in the second network component. The first network component detects a reception time upon receiving the returned message and stores corresponding reception time information of the message. The propagation time of the message along the communication connection is determined using the transmission time information of the message and the reception time information of the message. |

Application of force in electrochemical cells
The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging.

Disclosed herein are an interconnect for a solid oxide fuel cell and a method for manufacturing the same, the interconnect including: a conductive core; an oxidation-resistant insulating part receiving therein; and an oxidation-resistant conductive material layer coated on an exposed surface of the conductive core, which is exposed to an external environment by removing a portion of the oxidation-resistant insulating part, so that the interconnect can maintain durability against high-temperature heat generated from a flat type solid oxide fuel cell for a long time and thus have a very small voltage loss due to oxidation even with the use over a long-time period; have no sealing problem and no delaminating problem of a coating film due to a difference in coefficient of thermal expansion; be inexpensive; and have a simple structure. |
