SEMANTIC ANALYSIS

The owner has associated the following topics to the website.

The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by rosenberger.com.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
Milling (machining) Confidence: 78% Arrow up

Milling is the machining process of using rotary cutters to remove material from a workpiece by advancing (or feeding) in a direction at an angle with the axis of the tool.

It covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

It is one of the most commonly used processes in industry and machine shops today for machining parts to precise sizes and shapes.

Optical fiber Confidence: 76% Arrow up

An optical fiber or optical fibre is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.

Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.

Fibers are used instead of metal wires because signals travel along them with lesser amounts of loss; in addition, fibers are also immune to electromagnetic interference, a problem from which metal wires suffer excessively.

Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces, as in the case of a fiberscope.

Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers.

Telecommunication Confidence: 76% Arrow up

Telecommunication is the transmission of signs, signals, messages, writings, images and sounds or intelligence of any nature by wire, radio, optical or other electromagnetic systems.

Telecommunication occurs when the exchange of information between communication participants includes the use of technology.

It is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation.

Such transmission paths are often divided into communication channels which afford the advantages of multiplexing.

The term is often used in its plural form, telecommunications, because it involves many different technologies.

Germany Confidence: 74% Arrow up

Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe.

It includes 16 constituent states, covers an area of, and has a largely temperate seasonal climate.

With about 82 million inhabitants, Germany is the most populous member state of the European Union.

After the United States, it is the second most popular immigration destination in the world.

Germany's capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr (main centres: Dortmund and Essen).

Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, DĂ¼sseldorf and Leipzig.

High voltage Confidence: 73% Arrow up

The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms.

Equipment and conductors that carry high voltage warrant particular safety requirements and procedures.

In certain industries, high voltage means voltage above a particular threshold (see below).

High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and in high power amplifier vacuum tubes and other industrial and scientific applications.
