Abstract: A seismically suspended isolation device is installed in a suspended configuration at a fixed end and comprises a first support module, a second support module, a first displacement suppressing module and a second displacement suppressing module. The first support module includes a first fixing element, a first moving element, and at least one first roller. The first roller is disposed between the first fixing element and the first moving element. The second support module includes a second fixing element, a second moving element, and at least one second roller. The second roller is disposed between the second fixing element and the second moving element. The first support module and the second support module are stacked together in an orthogonal manner, so that the seismically suspended isolation device generates motion in the first direction and the second direction when the seismically suspended isolation device subjected to an external force.

Abstract: The invention discloses a method to set up a cross-domain DDS-secure network and then use it to transmit various kinds of data. To set up the cross-domain DDS-secure network, we first register IoT and monitor devices on the administration website. Second, we group devices based on our needs and then ask the website to generate configurations and certificates for each device. Finally, we download those files and deploy them to each device. In an extremely case, we can accomplish all operations only through a mobile device. During the system operating, all devices establish the DDS-secure connections to each other, and data will transmit on the network securely.

Abstract: A high-power seismic wave early warning method is provided to use an earliest-arriving seismic wave to estimate a maximum power value of a later-arriving high-power seismic wave for a target site. When the estimated maximum power value of the later-arriving high-power seismic wave is greater than a warning value, an earthquake early warning is transmitted to an earthquake early warning device that is located at the target site.

Abstract: A vacuum cathode arc-induced pulsed thruster includes a housing where a triggering room and an electric discharging room are defined and are in communication with each other, a first anode unit and a first cathode unit concentrically disposed in the triggering room, a second anode unit disposed in the electric discharging room, an insulating fuel layer concentrically located between the first anode unit and the first cathode unit, a main insulating layer concentrically surrounded by the first cathode unit, and a second cathode unit inserted from the triggering room into the electric discharging room. Thus, the vacuum cathode arc-induced pulse thruster is lightweight and has low manufacturing costs, low system complexity, and less energy consumption. Carbon deposition caused during an electric discharging process is prevented from affecting an inducing effect to thereby prolong the service life of the thruster and increase the control precision and inducing precision effectively.

Abstract: The present application is related to system and method for analyzing confidential data. Firstly, a first key is used to obtain a first analysis authorization for proceeding a first analysis responsive to an operational model in an encrypted cloud space with a connection of a network. Then, the result of the first analysis is verified. While the verifying of the operational model is pass, a second key is used to obtain a second analysis authorization for proceeding a second analysis responsive to an operational model without the connection of the network. Thereby, the cloud technique for analyzing data can be applied for analyzing confidential data.

Abstract: The present application reveals a system for computing and a method for arranging nodes thereof, which is applied for a remote host connected with a plurality of computing nodes divided to a plurality of first nodes and second nodes due to a first computing mode and a second computing mode. After the remote host receives a job, the remote host evaluates the computing nodes in accordance with the job and a corresponding priority weight parameter to generate a job beginning data to set the first nodes or the second nodes and to proceed the job. While setting the first or the second nodes, the remote host provides the corresponding system image to the corresponding nodes; while the first or the second nodes are full in resource arrangement, the empty nodes will be converted to the supplement nodes with the corresponding system image from the remote host.
