Abstract: Gas detection devices comprise a dehydration unit a concentration unit, and a temperature control unit for controlling a temperature. The gas detection device includes a sampling mode in which sample gas flows into and out of the dehydration unit through a first port and a second port, respectively, wherein the volatile organic compounds in the sample gas are concentrated in the concentration unit. The temperature control unit may be configured such that the temperature of the sample gas after flowing out from the dehydration unit and before flowing into the concentration unit is not greater than a first preset temperature. Generation of condensed substances in the sample gas can be effectively avoided in a simple manner after the sample gas flows into the concentration unit, thereby further preventing ice blockage. Methods for detecting volatile organic compounds in a sample gas are also disclosed.

Abstract: A machine learning application method, a device, an electronic apparatus, and a storage medium, used to directly link service scenarios, aggregate data related to the service scenarios, accordingly explore modeling schemes, and ensure that data used in offline modeling scheme exploration and data used in an online model prediction service have the same source, thereby realizing consistency of source of offline and online data. Directly deploying an offline model to an online environment results in data inconsistency between online feature computation and offline feature computation, which in turn causes poor prediction performance; therefore, only a modeling scheme is deployed online, and the offline model is not deployed. After a modeling scheme is deployed online, sample data having a feature and feedback can be obtained by receiving a prediction request, thereby enabling model self-learning by means of the sample data.

Abstract: A single, normally inactive, protection channel provides protection against transponder failure in a fiber optic ring network. The protection channel is established and put into operation by a series of steps that are triggered by the detection of loss of light from one transponder by the other transponder. Each node reacts to a loss of light from another node in the same way: by rerouting incoming traffic from external sources from a working input-output interface to a protection interface, to establish a path for the protection signal, and by sending a signal enabling the two nodes to resume communication.

Abstract: Embodiments of the present invention allow a method, device, software and apparatus to adjust a system parameter, such as a page closing time value, in order to enhance a processing device performance. For example, a method includes initializing a page closing time value by a BIOS software component. A processing device, such as a computer, operates responsive to the page closing time value. For example, the computer executes a graphic display software program. An operational value, such as a difference between page hits and page misses, is obtained while executing the software program and compared to a threshold value. The page closing time value is then adjusted responsive to the comparison. In an alternate embodiment of the present invention, an adaptive circuit is included in a memory controller and includes a first counter capable to obtain a number of page hits and a second counter capable to obtain a number of page misses.
