Since tone systems typically comprise fewer units than either consonant or vowel systems, we might expect that they would be the easiest part of a phonologic analysis.

Since the randomization-based analysis is complicated and is closely approximated by the approach using a normal linear model, most teachers emphasize the normal linear model approach.

Since E. histolytica does not form cysts in the absence of bacteria, E. invadens has become used as a model for encystation studies as it will form cysts under axenic growth conditions, which simplifies analysis.

Since its inception it has broadened to find applications in many other areas, including statistical inference, natural language processing, cryptography, neurobiology, the evolution and function of molecular codes, model selection in ecology, thermal physics, quantum computing, plagiarism detection and other forms of data analysis.

Since the actual physical surface of the Earth is too complex for mathematical analysis two levels of abstraction are employed in the definition of these coordinates.

Since the early 1960s, theoretical linguists have moved away from the traditional concept of a phoneme, preferring to consider basic units at a more abstract level, as a component of morphemes ; these units can be called morphophonemes, and analysis using this approach is called morphophonology.

Since Gettier proposed his counterexamples the traditional analysis has included the further claim that knowledge must be more than justified true belief.

Since the root can always be changed from red to black, but not necessarily vice-versa, this rule has little effect on analysis.

Since the mid-1990s, starspot observations have been made using increasingly powerful techniques yielding more and more detail: photometry showed starspot growth and decay and showed cyclic behavior similar to the Sun's ; spectroscopy examined the structure of starspot regions by analyzing variations in spectral line splitting due to the Zeeman Effect ; Doppler imaging showed differential rotation of spots for several stars and distributions different from the Sun's ; spectral line analysis measured the temperature range of spots and the stellar surfaces.

Since SignWriting is pictographic, in the unusual sense of being an iconic featural script, no phonemic analysis of a language is required to write it with SignWriting.

Since orbital energies are unique to an atom of a specific element, analysis of the ejected electrons can yield information about the chemical composition of a surface.

Since many factors are considered for landslide hazard mapping, GIS is an appropriate tool because it has functions of collection, storage, manipulation, display, and analysis of large amounts of spatially referenced data which can be handled fast and effectively.

Since they are produced automatically without any rational analysis and verification ( see the modern idea of the subconscious ) of whether they are correct or not, they need to be confirmed ( epimarteresis: confirmation ), a process which must follow each assumption.

Since basic blocks have no control flow, these optimizations need very little analysis ( saving time and reducing storage requirements ), but this also means that no information is preserved across jumps.
