Sport (shipwreck). The Sport was a tugboat, built in 1873 and wrecked in 1920 in Lake Huron, in the United States. The wreck site, designated 20UH105, was listed on the National Register of Historic Places in 1992.

History
In 1873, lumber and steel entrepreneur Eber Brock Ward commissioned Frank E. Kirby to design this tug. The boat was built by the Wyandotte Iron Ship Building Works in Wyandotte, Michigan. The Sport was the first steel tug on the Great Lakes, and the first vessel made of Bessemer steel in North America. It was designed as a harbor tug, and first used around Wyandotte and the St. Clair River. By 1875, she was assigned to Ludington, Michigan, where Ward owned sawmills. The tug was rebuilt a number of times, and sold to a succession of owners who used it for towing, salvaging and aiding vessels in distress. 

In 1913, the Sport was sold a final time to Captain Robert Thompson of Port Huron, Michigan. Thompson used it as a fire tug in Port Huron, and for other harbor duties.

On December 13, 1920, the Sport set out from Port Huron, bound for Harbor Beach. It encountered a heavy gale, and by 6:00 pm was taking on more water than could be pumped out. The seasick and exhausted firetender returned to his bunk, and the boat lost steam, killing the pumps. The crew abandoned ship at about 11:00 pm, and washed ashore near Lexington, still alive.

The wreck of the Sport was discovered in 1987. In 1992, the Sport became the first Michigan shipwreck with her own Michigan Historical Marker placed on her. The wreck is now part of the Sanilac Shores Underwater Preserve, and popular with divers. The marker was damaged and removed in 2002.

Description
The Sport was 57 feet long, with a beam of 14 feet, and a depth of 9 feet. It had a net tonnage of 23 tons and gross tonnage of 45 tons. The boat had an iron frame with a steel hull over it.

The wreck is in 45 feet of water, with the hull resting upright, listing slightly to starboard. The upper sections of the tug project 20 feet off the bottom. The boat is intact, and a number of tools and relics are scattered around the site.

Battery simulator. A battery simulator is an electronic device designed to test battery chargers by simulating the behavior of a battery during the charging process.

Characteristics 
Highlights in the battery simulator are the IGBT or MOSFET high frequency regulator (which allows the equipment to work with constant current and voltage), the programmable digital panel.

A battery simulator may have the following features:
 An IGBT or MOSFET high frequency regulator
 Digital voltmeter
 Analogue ammeter
 Test voltage selector
 Potentiometer fine tension adjustment.
 Potentiometer current selection (0-200 A)
 self-test
 Automatic stop in case of failure
 Thermal protection in case of overtemperature

Functioning 
Battery simulator mimics a battery's electrical characteristic of outputting a voltage and is able to source as well as sink current. This type of power supply is called two-quadrant power supply. In contrast, a conventional power supply can only source current when the voltage is positive.

A battery simulator may be able to set the simulated battery voltage either remotely via PC or manually. Often battery simulators have built-in voltage and current display and monitoring. For example, the user selects the voltage of the battery to be simulated, using the potentiometer knob for adjusting the voltage, while the current value is displayed on the digital screen. An independent potentiometer is available to select the maximum current that the equipment can source or sink.

Battery Charger Testing 

The basic use of battery simulator is replacing a real battery with a simulator. This enables the testing of the charger both during development and during production testing.

Once the simulated battery voltage is set, the user connects the charger to be tested to the input of the simulator. The charger will detect that a battery has been connected and the charging process will begin. The simulator keeps the voltage constant at the set value, while the analogue ammeter indicates the charging current. If the battery simulator has a current limit feature and if the current exceeds the maximum set value, the simulator automatically increases the voltage to limit the current

The advantage of using a battery simulator is its ability to freely set the emulated battery voltage to any value in order to test the charger. For example, a real charger profile curved is obtained by sweeping the simulator voltage while recording its voltage and current. The figure to the right shows a typical Lithium ion charging profile curve obtained by using a battery simulator. The profile curve of the charger is obtained in a few minutes.

Concise Command Language. Concise Command Language (CCL) was the term used by Digital Equipment Corporation for the Command-line interpreter / User interface supplied on several of their computing systems; its successor was named DIGITAL Command Language (DCL).

CCL provides the user with an extensive set of terminal commands.

The first system to include CCL was DEC's PDP-10.

History
The PDP-6 monitor came with a simple set of commands. To compile and run a FORTRAN program, one would
 .R F4 --- invoke the FORTRAN compiler
 *DTA1:PROG3=DTA2:PROG3,SUB3A,SUB3B  --- specify binary output and source input
 .R LOADER 30  --- invoke the loader, allocate 30K of memory
 *DTA1:PROG3   --- specify binary object to load
 *SYS:/S  --- let the loader find the appropriate subroutine libraries
 .SAVE DTA1:PROG3  --- write the executable to DTA1
(The DOT is a monitor prompt and the Star/Asterisk is an application prompt)

The PDP-10 had CCL. Key to its improvements over its predecessor were:
 multi-step commands: .EX PROG3,SUB3A,SUB3B
 would check to see if any of the 3 needed to be recompiled (and did so if necessary)
 run the object program loader (including needed subroutine libraries)
 start running the program
 advanced command file: .EX @RUNPROG3.CMD
 would run the command(s) in the .CMD file

Commands
The following table contains a list of CCL commands.

IEEE 1849. The IEEE STANDARD 1849-2016, IEEE Standard for eXtensible Event Stream (XES) for Achieving Interoperability in Event Logs and Event Streams, is a technical standard developed by the IEEE Standards Association. It standardizes "a language to transport, store, and exchange (possibly large volumes of) event data (e.g., for process mining)". In 2023, the standard has been revised in and superseded by the IEEE Standard 1849-2023.

Process mining aims to discover, monitor and improve processes by extracting knowledge from event logs representing actual process executions in a given setting. Process mining depends on the availability of accurate and unambiguous event logs, according to established standards. The purpose of this standard is to provide a generally acknowledged (W3C) XML format for the interchange of event data between information systems in many applications domains on the one hand and analysis tools for such data on the other hand. As such, this standard aims to fix the syntax and the semantics of the event data which, for example, is being transferred from the site generating this data to the site analyzing this data. As a result of this standard, if the event data is transferred using the syntax as described by this standard, its semantics will be well understood and clear at both sites.

IEEE 1849 was the second IEEE Standard Sponsored by the IEEE Computational Intelligence Society. The first was IEEE 1855.

IEEE Standard 1849-2023 
The 2023 revision of the standard has been approved on the 5th of June 2023 and introduces the following changes:

 new Micro, Software Event, Software Communication, Software Telemetry, and Artifact Lifecycle extensions
 updated lists of tools supporting the standard, event logs using the standard, and publications that mention the standard 
 updated XES Schema definition, fixing a flaw related to the position of the log attributes
 updated bibliography
