  2. Column family - Wikipedia

    en.wikipedia.org/wiki/Column_family

    In analogy with relational databases, a column family is as a "table", each key-value pair being a "row". Each column is a tuple consisting of a column name, a value, and a timestamp. In a relational database table, this data would be grouped together within a table with other non-related data. Two types of column families exist:

  3. Buckling - Wikipedia

    en.wikipedia.org/wiki/Buckling

    A short steel column is one whose slenderness ratio does not exceed 50; an intermediate length steel column has a slenderness ratio ranging from about 50 to 200, and its behavior is dominated by the strength limit of the material, while a long steel column may be assumed to have a slenderness ratio greater than 200 and its behavior is dominated ...

  4. Line length - Wikipedia

    en.wikipedia.org/wiki/Line_length

    The matrix is used by locating the number closest to the previously calculated LCA on the left column of the matrix and then scanning across the columns the number of characters that one would like to set in the text line. Once the number is located, the top row of the selected column will indicate the ideal line length. [13]

  5. Qinling panda - Wikipedia

    en.wikipedia.org/wiki/Qinling_panda

    Most Qinling pandas are around the same size as giant pandas, growing to 1.2–1.8 m (3 ft 11 in – 5 ft 11 in) in length and 70–80 cm (28–31 in) at shoulder height. The males of the species are heavier than females, weighing roughly 60–190 kg (130–420 lb) whereas females are likely to weigh 75–125 kg (165–276 lb).

  6. Johnson's parabolic formula - Wikipedia

    en.wikipedia.org/wiki/Johnson's_parabolic_formula

    The slenderness ratio is an indicator of the specimen's resistance to bending and buckling, due to its length and cross section. If the slenderness ratio is less than the critical slenderness ratio, the column is considered to be a short column. In these cases, the Johnson parabola is more applicable than the Euler formula.

  7. PANDAS - Wikipedia

    en.wikipedia.org/wiki/PANDAS

    The children originally described by Susan Swedo et al. (1998) [17] usually had an abrupt onset of symptoms, including motor or vocal tics, obsessions, or compulsions. [18] [19] In addition to an obsessive–compulsive or tic disorder diagnosis, children may have other symptoms associated with exacerbations such as emotional lability, enuresis, anxiety, and deterioration in handwriting.

  8. Word list Drawing up a comprehensive list of words in English is important as a reference when learning a language as it will show the equivalent words you need to learn in the other language to achieve fluency.

  9. Euclidean vector - Wikipedia

    en.wikipedia.org/wiki/Euclidean_vector

    A unit vector is any vector with a length of one; normally unit vectors are used simply to indicate direction. A vector of arbitrary length can be divided by its length to create a unit vector. [14] This is known as normalizing a vector. A unit vector is often indicated with a hat as in â.
