Structural Holes: Unpacking Burt's Redundancy Measures In Structural Holes, Ron Burt (1992; 1995) describes a set of new measures based on ego networks. One key set of measures is concerned with the notion of redundancy. The general meaning of redundancy is clear: a person's ego network has redundancy to the extent that her contacts are connected to each other as well.or example, on page 53 of Structural Holes, Table 2.1 gives the effective sizes of six networks. One of them is ... Table 2.1 gives the effective size of this ego network as 4, but this is clearly wrong: the effective size is 7, yielding an efficiency score of 0.875.

- The Basics of a Helical Deep Foundation. A helical foundation consists of at least one helix-shaped steel bearing plate attached to a central steel shaft. The shaft is typically solid steel bar (12 to 23 inches square) or heavy wall pipe (2f to 8 inches in diameter).The helix plates are high-strength steel (6 to 16 inches in diameter, d or 2 inch thick).oils: Helical foundations can be installed into soils with a blow count (N-value) less than 80 blows/foot of the 2-inch OD sampler per ASTM D-1586. A limitation of screw foundations is they cannot be installed into competent rock or very hard, dense soil greater than about 80 blows/foot.

- Molly bolts are anchor bolts with expandable sleeves that are used to fasten objects to drywall. Molly bolts have pointed ends and expandable sleeves.When a molly bolt is inserted into a pre-drilled hole and the bolt is tightened, the threaded sleeves expand anchoring the molly bolt into the wall.nsert the molly bolt pointed-end first into the pilot hole and lightly tap the head of the molly bolt using a hammer. The amount of force that you need to affix the molly bolt into the pilot hole depends on the size of your pilot hole.

Structural engineering Structural engineering theory is based upon applied physical laws and empirical knowledge of the structural performance of different materials and geometries. Structural engineering design utilizes a number of simple structural elements to build complex structural systems. Structural engineers are responsible for making creative and efficient use of funds, structural elements and materials to achieve these goals.

Where is the hole in this rational function f  (x)=x2 + 2 x â 8x 2 â x â 2? Jun 5, 2015. Hole is a 'common' term for removable discontinuities for a rational function f(x) which can be expressed as a quotient of two polynomial functions in the form of f(x)=p(x)q(x) . The following tutorial discusses the concept in detail. Step I : We need to factorize the polynomials in the numerator and denominator.

How to Know When Ceiling Cracks Are Structural or Just Old Cracks that cause concern are those which run across the length of a ceiling and then continue down a wall along the same line. This is a sign of structural damage, usually related to a weak wall stud or perhaps something that was jarred loose in an earthquake or the settling of the home over time.hey can run throughout the home, not only on the ceiling but also on the walls, floors, grout joints in tile installations and concrete slabs. Alternatively, large cracks that are more than 1/16 inch wide are a sign of structural issues and should be dealt with.
