Master of Science

A Master of Science degree (Latin: Magister Scientiae; abbreviated M.S., MS, M.Sc., MSc, M.Sci., MSci, S.M., Sc.M., or Sci.M.) is a type of master's degree awarded by universities in many countries. The degree is usually contrasted with the Master of Arts degree. The Master of Science degree is typically granted for studies in the sciences or engineering or medicine, and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, individuals who pursue a Master of Science degree typically require a thesis.

Algeria

Algeria follows the Bologna process for higher education in Europe.

Argentina, Brazil, Mexico, Colombia, Perú and Uruguay

In Argentina, Brazil, Ecuador, Mexico, Colombia, Perú and Uruguay, the Master of Science or Magister is a postgraduate degree of two to four years of duration. The admission to a Master's program (Spanish: Maestría; Portuguese: Mestrado) requires the full completion of a four to five years long undergraduate degree, bachelor's degree or a Licentiate's degree of the same length. Defense of a research thesis is required. All master's degrees qualify for a doctorate program.

Decibel

The decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, often power or intensity. One of these values is often a standard reference value, in which case the decibel is used to express the level of the other value relative to this reference. The number of decibels is ten times the logarithm to base 10 of the ratio of two power quantities, or of the ratio of the squares of two field amplitude quantities. One decibel is one tenth of one bel, named in honor of Alexander Graham Bell; however, the bel is seldom used.

The definition of the decibel is based on the measurement of power in telephony of the early 20th century in the Bell System in the United States. Today, the unit is used for a wide variety of measurements in science and engineering, most prominently in acoustics, electronics, and control theory. In electronics, the gains of amplifiers, attenuation of signals, and signal-to-noise ratios are often expressed in decibels. The decibel confers a number of advantages, such as the ability to conveniently represent very large or small numbers, and the ability to carry out multiplication of ratios by simple addition and subtraction. By contrast, use of the decibel complicates operations of addition and subtraction.
