Various hardware and software solutions exist for collecting Controller Area Network (CAN) bus data. Digital data accuracy could vary based upon different data logging methods (e.g., hardware/software timing, processor timing, etc.). CAN bus data were collected from agricultural tractors using multiple data acquisition solutions to quantify differences among collection methods and demonstrate p...

sustainable forest management in caspian forests of iran requires cost-benefit analysis in order to maintain the quality of timber stands during logging operations. this study was done with the aim of cost and gross revenue computations from current logging (net present value) in three adjacent compartments in district 2 of shafroud watershed. motion and time studies were carried out during fel...

Third, error logging and reporting is important. As an industry, we currently support very primitive logging with no mechanisms for root-cause analysis or correlation of failures. Error messages are often arcane or not useful, and “firstfailure” capture is impossible. This is evidenced by a common, though unrealistic, request from support center staff: “Turn logging on and recreate the failure....

This paper presents two algorithms for maintaining Btree index consistency in a DBMS which does not use write-ahead logging (WAL). One algorithm is similar to shadow paging, but improves performance by integrating shadow meta-data with index meta-data. The other algorithm uses a two-phase page reorganization scheme to reduce the space overhead caused by shadow paging. Although designed for the ...

This paper presents a custom bit error rate (BER) tester implementation in an Altera Stratix II GX signal integrity development kit. This BER tester deploys a parallel to serial pseudo random bit sequence (PRBS) generator, a bit and link status error detector and an error logging FIFO. The auto-correlation pattern enables receiver synchronization without specifying protocol at the physical laye...

The use of advanced and emerging remote data-collection technologies, and in particular bio-logging of marine migratory species, raises fundamental questions about the scope of authority of coastal states to regulate marine scientific research in the waters under their jurisdiction. Bio-logging involves the attachment of devices to marine animals that collect and transmit data about their movem...
