Data logger

A data logger (also datalogger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer, and use software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device.

Data loggers vary between general purpose types for a range of measurement applications to very specific devices for measuring in one environment or application type only. It is common for general purpose types to be programmable; however, many remain as static machines with only a limited number or no changeable parameters. Electronic data loggers have replaced chart recorders in many applications.

Logarithm

In mathematics, the logarithm is the inverse operation to exponentiation. That means the logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In simple cases the logarithm counts repeated multiplication. For example, the base 10 logarithm of 1000 is 3, as 10 to the power 3 is 1000 (1000 = 10 × 10 × 10 = 10³); the multiplication is repeated three times. More generally, exponentiation allows any positive real number to be raised to any real power, always producing a positive result, so the logarithm can be calculated for any two positive real numbers b and x where b is not equal to 1. The logarithm of x to base b, denoted log_b(x), is the unique real number y such that

For example, as 64 = 2⁶, we have

The logarithm to base 10 (that is b = 10) is called the common logarithm and has many applications in science and engineering. The natural logarithm has the number e (≈ 2.718) as its base; its use is widespread in mathematics and physics, because of its simpler derivative. The binary logarithm uses base 2 (that is b = 2) and is commonly used in computer science.

Gravedigger

A gravedigger is a cemetery worker responsible for digging a grave prior to a funeral service.

Description

If the grave is in a cemetery on the property of a church or other religious organization (part of, or called, a churchyard), gravediggers may be members of the decedent's family or volunteer parishioners. Digging graves has also been one of the traditional duties of a church's sexton. In municipal and privately owned cemeteries, gravediggers may be low-paid, unskilled, and temporary laborers, or they may be well-paid, trained, and professional careerists, as their duties may include landscaping tasks and courteous interactions with mourners and other visitors. In some countries, gravedigging may be done by landscaping workers for the local council or local authority.

A gravedigger implements a variety of tools to accomplish his primary task. A template, in the form of a wooden frame built to prescribed specifications, is often placed on the ground over the intended grave. The gravedigger may use a sod-cutter or spade to cut the outline of the grave and remove the top layer of sod. Digging the grave by hand usually requires shovels, picks, mattocks, and/or other tools. Cemeteries in industrialized countries may keep a backhoe loader and other heavy equipment, which greatly increases the efficiency of gravedigging.

Gravedigger (song)

"Gravedigger" is a song by Dave Matthews from his debut solo album, Some Devil. This was the first solo single released by Matthews away from the Dave Matthews Band, and it won a Grammy Award for Best Male Rock Vocal Performance at the 46th Grammy Awards held on February 8, 2004. The song has been performed live by Dave Matthews (solo), by Dave Matthews with Tim Reynolds, at Dave Matthews & Friends concerts, and occasionally as an acoustic solo by Matthews during Dave Matthews Band shows. During the Dave Matthews Band's tours in 2008 and 2009, it was played regularly by the full band.

Matthews said about the song:

There was also an acoustic version of the song on the album Some Devil. The song began as an intro played twice solo by Matthews at full-band DMB shows in the spring of 2002, before debuting as a full solo song in the same tour. In the original "Gravedigger Intro" version, only two people are mentioned: Merrill Lee (1905–1969) and Robert John Smith.
