Analyzing log data, such as security log data and event data, is disclosed. Log data is received. Portions of the log data are clustered into clusters of similar data portions. A signature for each cluster is generated. Comparison of subsequent log data with the signature indicates whether the subsequent log data belongs in the cluster.

A method of producing a crude syngas product stream or a syngas product stream by further processing of the crude syngas product stream. Both the crude and syngas product stream comprise carbon monoxide and hydrogen. The crude syngas product stream additionally comprises carbon dioxide and moisture. In accordance with the method, methane in a feed stream is converted into the hydrogen and carbon monoxide in at least two stages, thereby to form a crude syngas stream. An initial stage has an oxygen transport membrane reactor having a catalyst to promote carbon dioxide or steam methane reforming. Since, the conversion is shared between two stages, the oxygen transport membrane reactor can be operated at a sufficiently low temperature to avoid ceramic membrane deterioration due to creep effect. The subsequent stage can be operated at a higher temperature with more favorable equilibrium conditions to complete the conversion of the methane.

In a method for the production of carbon dioxide, an oxygen-containing first process gas is flowed along a cathode side of a first oxygen selective ion transport membrane. The membrane is at operating conditions effective to transport a first permeate oxygen portion from the cathode side to an opposite anode side. A carbon-containing second process gas is flowed along the anode side at a flow rate effective to provide a stoichiometric surplus of oxygen on combination with the first permeate oxygen portion. A first mixture of a second process gas and the first permeate oxygen portion is combusted such that substantially all of the second process gas is converted into a second mixture of water and carbon dioxide. The carbon dioxide is separated from such second mixture.

An exothermic reaction and an endothermic reaction are thermally combined in a reactor having at least one oxygen selective ion transport membrane that provides the exothermic reaction with oxygen from an oxygen-containing gas such as air. The thermal requirements of the endothermic reaction are satisfied by the exothermic reaction. Dependent on the reactor design employed, the exothermic and endothermic reactions may be gaseously combined.

An ozonizer is disclosed, having a first electrode and a second electrode between which a discharge gap is formed, a dielectric being arranged between the first electrode and the second electrode. The dielectric comprises a support element made of glass or glass ceramic, onto which a thin dielectric film on the order of up to 100 &mgr;m is applied. The use of glass or glass ceramic as the dielectric, in conjunction with an additional thin ceramic dielectric film, allows a considerable improvement in the ozone concentration in the carrier gas, simultaneously with a good ozone yield.
