Analog (program)

Analog is a free web log analysis computer program that runs under Windows, Mac OS, Linux, and most Unix-like operating systems. It was first released on June 21, 1995, by Stephen Turner as generic freeware; the license was changed to the GNU General Public License in November 2004. The software can be downloaded for several computing platforms, or the source code can be downloaded and compiled if desired.

Analog has support for 35 languages, and provides the ability to do reverse DNS lookups on log files, to indicate where web site hits originate. It can analyze several different types of web server logs, including Apache, IIS, and iPlanet. It has over 200 configuration options and can generate 32 reports. It also supports log files for multiple virtual hosts.

The program is comparable to Webalizer or AWStats, though it does not use as many images, preferring to stick with simple bar charts and lists to communicate similar information. Analog can export reports in a number of formats including HTML, XHTML, XML, Latex and a delimited output mode (for example CSV) for importing into other programs. Delimited or "computer" output from Analog is often used to generate more structured and graphically rich reports using the third party Report Magic program.

Analogue electronics

Analogue electronics (or analog in American English) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term "analogue" describes the proportional relationship between a signal and a voltage or current that represents the signal. The word analogue is derived from the Greek word ανάλογος (analogos) meaning "proportional".

Analogue signals

An analogue signal uses some attribute of the medium to convey the signal's information. For example, an aneroid barometer uses the angular position of a needle as the signal to convey the information of changes in atmospheric pressure. Electrical signals may represent information by changing their voltage, current, frequency, or total charge. Information is converted from some other physical form (such as sound, light, temperature, pressure, position) to an electrical signal by a transducer which converts one type of energy into another (e.g. a microphone).

Structural analog

Structural analogs (structural analogue or simply analog) are models or representations that keep each other certain "structural similarity". It is used in engineering, chemistry, mathematics and other fields.

Despite the field diversity, all structural analog analysis use some level of abstraction to transform models in mathematical graphs, and detected structural analogies by algorithms. Example: for molecular structure comparison and classification operations, the compared compounds are modeled as a mathematical graph. Formally, when structures are represented by graphs, the concept of analog is related to a graph isomorphism.

Systems engineering

Analogical models are used in a method of representing a ‘target system’ by another, more understandable or analysable system.

Two systems have analog structures (see illustration) if they are isomorphic graphs and have equivalent (mapped) lumped elements. In Electronics, methods based on fault models of structural analogs gain some acceptance in industry.

Dancing (Elisa song)

"Dancing" was the fourth single released in Italy and the United states from Elisa's third album, Then Comes the Sun, and the first single released from her American album Dancing.

Dancing (album)

Dancing is a compilation album by Italian singer Elisa that was released on July 15, 2008 in CD format in the United States and Canada. A digital version on iTunes was released on June 17, 2008 in the United States and on August 25, 2008 in Canada.

The album, released as part of an effort to introduce Elisa to North American audiences, is a compilation of recordings (some remixed) from previously released albums dating back to 2000.

Released of the full album was preceded by the released of an EP featuring the song "Dancing" which was released in December 2007. Beside the title track, the EP includes "Rock Your Soul" (also included on the Dancing album), along with a live version of '"Dancing'" recorded at the iTunes Festival in London.

The first single from the album is Rainbow in a new remix edition by Glen Ballard.

Track origins

The songs on the album were chosen by Elisa and are culled from most of her albums, with the exception of her first, Pipes & Flowers.

There is only one song from her second album Asile's World (2000): "A Little Over Zero." However this is a remixed version of the original.
