Abstract: The present disclosure relates to a lighting system. The lighting system may include a first housing, a second housing, one or more drivers, and one or more lighting devices. The first housing defines a first hollow portion. The second housing may be pivotably coupled to the first housing and define a second hollow portion opposite to the first hollow portion, such that the first hollow portion and the second hollow portion together define an interior space. Further, the one or more drivers may be disposed in the first hollow portion of the first housing. Moreover, the one or more lighting devices may be disposed in the second hollow portion of the second housing and electrically connected to the one or more drivers.

Abstract: Methods and server systems for performing merchant classification are described herein. The method performed by a server system includes accessing a historical transaction dataset including transaction attributes from a database. Method includes generating a set of key performance features for each merchant of the plurality of merchants based on the historical transaction dataset. Method includes determining a set of hyper-parameters including an epsilon value and a Minimum points (MinPts) value for a clustering machine learning (ML) model based on a K-nearest neighbor (KNN) plot generated based on the set of key performance features for each merchant. Method includes generating via the clustering ML model, a set of merchant clusters based on the set of key performance features for each merchant and the set of hyper-parameters. Method includes labeling each merchant cluster as one of a first merchant class and a second merchant class based on a classification threshold.

Abstract: A monitoring device for a cathodic protection system of a metallic structure comprises a sensor module configured for measuring an electrical signal indicative of a DC signal and an AC signal of the cathodic protection system, a control module and a communication module operatively coupled to a central processing device of the cathodic protection system. The control module is configured to switch the monitoring device between a sleep mode and an active mode. Further, the monitoring device, when being in the active mode, is configured to obtain the electrical signal, apply a first filter on the signal to obtain at least one filtered signal, convert the at least one filtered signal into at least one digital signal, apply a second filter to obtain at least one filtered digital signal and forward the at least one filtered digital signal to the central processing device. Further, a cathodic protection system is described.

Abstract: A grounding resistance surveillance system comprises a plurality of measurement devices configured for measuring a grounding resistance value and being arrangeable at different locations within a target area, and at least one gateway device. Each of the plurality of gateway devices is communicatively coupled to at least one further measurement device of the plurality of measurement devices, and at least one measurement device of the plurality of measurement devices is in direct communication to the at least one gateway device and at least one measurement device of the plurality of measurement devices is only in indirect communication to the at least one gateway device such that a mesh network of coupled measurement devices is formed. The grounding resistance surveillance system is configured to execute a method for determining a grounding resistance in the target area. Further, a measurement device for a grounding resistance surveillance system is described.

Abstract: A method, non-transitory computer readable medium, and apparatus that obtains a version history for a plurality of source code files associated with the computer program. At least one defect probability value is generated for each of the plurality of source code files using at least one metric and the obtained version history. One or more of the plurality of source code files having a higher risk of including one or more defects than one or more other of the plurality of source code files are identified based on the generated defect probability values. Information regarding each of the one or more identified source code files is output.
