  2. Satellite DNA - Wikipedia

    en.wikipedia.org/wiki/Satellite_DNA

    Satellite DNA consists of very large arrays of tandemly repeating, non-coding DNA.Satellite DNA is the main component of functional centromeres, and form the main structural constituent of heterochromatin.

  3. Sparse matrix - Wikipedia

    en.wikipedia.org/wiki/Sparse_matrix

    In numerical analysis and scientific computing, a sparse matrix or sparse array is a matrix in which most of the elements are zero. [1] There is no strict definition regarding the proportion of zero-value elements for a matrix to qualify as sparse but a common criterion is that the number of non-zero elements is roughly equal to the number of ...

  4. Gene cluster - Wikipedia

    en.wikipedia.org/wiki/Gene_cluster

    Tandem arrays are a group of genes with the same or similar function that are repeated consecutively without space between each gene. The genes are organized in the same orientation. [ 10 ] Unlike gene clusters, tandemly arrayed genes are found to consist of consecutive, identical repeats, separated only by a nontranscribed spacer region.

  5. Array (data type) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_type)

    An array data structure can be mathematically modeled as an abstract data structure (an abstract array) with two operations get(A, I): the data stored in the element of the array A whose indices are the integer tuple I. set(A, I, V): the array that results by setting the value of that element to V. These operations are required to satisfy the ...

  6. Data cube - Wikipedia

    en.wikipedia.org/wiki/Data_cube

    Multi-dimensional arrays have long been familiar in programming languages. Fortran offers arbitrarily-indexed 1-D arrays and arrays of arrays, which allows the construction of higher-dimensional arrays, up to 15 dimensions. APL supports n-D arrays with a rich set of operations. All these have in common that arrays must fit into the main memory ...

  7. Array (data structure) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_structure)

    In computer science, an array is a data structure consisting of a collection of elements (values or variables), of same memory size, each identified by at least one array index or key. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula.

  8. Tensor - Wikipedia

    en.wikipedia.org/wiki/Tensor

    The definition of a tensor as a multidimensional array satisfying a transformation law traces back to the work of Ricci. [1] An equivalent definition of a tensor uses the representations of the general linear group. There is an action of the general linear group on the set of all ordered bases of an n-dimensional vector space.

  9. Photovoltaic system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_system

    A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
