  2. Standard penetration test - Wikipedia

    en.wikipedia.org/wiki/Standard_penetration_test

    The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...

  3. Social penetration theory - Wikipedia

    en.wikipedia.org/wiki/Social_penetration_theory

    The social penetration theory (SPT) proposes that as relationships develop, interpersonal communication moves from relatively shallow, non-intimate levels to deeper, more intimate ones. [1] The theory was formulated by psychologists Irwin Altman of the University of Utah [2] and Dalmas Taylor of the University of Delaware [3] in 1973 to ...

  6. Spanning Tree Protocol - Wikipedia

    en.wikipedia.org/wiki/Spanning_Tree_Protocol

    The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails.

  7. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils. Based on this history it has also been called the "Dutch ...
