Abstract: Embodiments are described for a system comprising a first database server comprising a first master database and a first user database and a second database server comprising a second master database and a second user database. The first database server is configured to select one or more encryption keys from the first master database and the first user database; generate a database backup file based on data content of the first user database and the one or more encryption keys, wherein the data content is encrypted by at least one data encryption key of the one or more encryption keys. The first database server is further configured to encrypt the one or more encryption keys with asymmetric keys or passwords and transmit the database backup file to the second database server.

Abstract: Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The heating of the pyrolysis environment can be performed at least in part by using electrical heating within a first stage to heat the coke particles to a desired pyrolysis temperature. This electrical heating can be performed in a hydrogen-rich environment in order to reduce, minimize, or eliminate formation of coke on the surfaces of the electrical heater. The heated coke particles can then be transferred to a second stage for contact with a methane-containing feed, such as a natural gas feed. Depending on the configuration, pyrolysis of methane can potentially occur in both the first stage and second stage. In some aspects, the hydrogen-rich environment in the first stage is formed by passing the partially converted effluent from the second stage into the first stage.

Abstract: Disclosed herein are system, method, and computer program product embodiments for securely performing a password change. An embodiment operates by receiving a password change request from a user. The password change request comprises an encrypted version of a new password for the user, a cleartext version of the new password, and a login name for the user. The embodiment then executes a command from a password rotator user account with the cleartext version of the new password, the encrypted version of the new password, and the login name. The embodiment then retrieves a public key associated with the login name. The embodiment then determines, based on the public key, that the password change request comes from the user and that the cleartext version of the new password has not been modified. The embodiment then sets the password of a user login associated with the user to the new password.

Abstract: Systems and methods are provided for production of carbon nanotubes and H2 using a reaction system configuration that is suitable for large scale production. In the reaction system, a substantial portion of the heat for the reaction can be provided by using a heated gas stream. Optionally, the heated gas stream can correspond to a heated H2 gas stream. By using a heated gas stream, when the catalyst precursors for the floating catalyst-chemical vapor deposition (FC-CVD) type catalyst are added to the gas stream, the gas stream can be at a temperature of 1000° C. or more. This can reduce or minimize loss of catalyst precursor material and/or deposition of coke on sidewalls of the reactor. Additionally, a downstream portion of the reactor can include a plurality of flow channels of reduced size that are passed through a heat exchanger environment, such as a shell and tube heat exchanger.

Abstract: Embodiments afford secure transfer of security key type(s) between different database servers having different key hierarchies. For example, a key transfer may occur from a source server to a target server during a database migration process. Particular embodiments comprise a SQL transfer command statement (e.g., TRANSFER ENCRYPTION KEY) recognized by an engine. Syntax of the SQL transfer command includes a password and a filename for a security key. Upon receiving the SQL transfer command, the engine references an information repository to identify a relevant key hierarchy and key type, encrypts the security key with a key derived from password, and stores (exports) the encrypted security key in a file for consumption (import) at the target server. The SQL transfer command may further comprise a direction component determining flow of key information, and an override function to deal with error messages arising from any already-existing security key having the same name.

Abstract: Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The conversion of hydrocarbons to hydrogen is performed in one or more pyrolysis or conversion reactors that contain a plurality of sequential fluidized beds. The fluidized beds are arranged so that the coke particles forming the fluidized bed move in a counter-current direction relative to the gas phase flow of feed (e.g., methane) and/or product (H2) in the fluidized beds. By using a plurality of sequential fluidized beds, the heat transfer and management benefits of fluidized beds can be realized while also at least partially achieving the improved reaction rates that are associated with a plug flow or moving bed reactor.

Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.

Abstract: Systems and methods are provided for separating oxygen from air using a sorption/desorption cycle that includes a reduced or minimized difference between the maximum and minimum pressures involved in the sorption/desorption cycle. The reduced or minimized difference in pressures can be achieved in part by using valves that can allow for commercial scale flow rates while avoiding large pressure drops for flows passing through the valves. A rotary wheel adsorbent is an example of a system that can allow for a sorption/desorption cycle with reduced and/or minimized pressure drops across valves associated with the process. Stationary adsorbent beds can also be used in combination with commercially available valves that have reduced and/or minimized pressure drops.
