Engineering demand functions for RC medium length span bridges

Bulletin of Earthquake Engineering, 2014
The evolution of the seismic design philosophies and the strong correlation of some structural demands with damage, motivate the research community to improve the knowledge about the pier demands in bridges. The seismic demands can be determined by conducting non-linear time history analyses, however, the computational time required can be excessive ...

Constructing minimal spanning/Steiner trees with bounded path length

Integration, 1997
Summary: This paper presents an exact algorithm and two heuristics for solving the Bounded path length Minimal Spanning Tree (BMST) problem. The exact algorithm which is based on iterative negative-sum-exchanges(s) has polynomial space complexity and is hence more practical than the method presented by Gabow. The first heuristic method (BKRUS) is based

Optimum Spans' Lengths of Multi-span Reinforced Concrete Beams Under Dynamic Loading

In the design of continuous beams, say bridges, achieving an economical layout is one of the primary objectives, and requires simultaneous consideration of cost and layout variables. This study aims to figure out an explicit methodology for the optimum layout design of multi-span reinforced concrete beams under dynamic loadings in order to optimize the

Polynomial-Length Planning Spans the Polynomial Hierarchy

2002
This paper presents a family of results on the computational complexity of planning: classical, conformant, and conditional with full or partial observability. Attention is restricted to plans of polynomially-bounded length. For conditional planning, restriction to plans of polynomial size is also considered.

Natural Frequencies of Continuous Beams of Uniform Span Length

Journal of Applied Mechanics, 1950
Abstract A simple graphical network is used to determine the natural frequencies of flexural vibration of continuous beams having any number of spans of uniform length. The network is based upon a relatively few calculated values.

Casein kinases phosphorylate multiple residues spanning the entire hnRNP K length

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2006
Heterogeneous Nuclear Ribonucleoprotein K (hnRNP K) is an RNA/DNA-binding protein involved in many processes that regulate gene expression. K protein's pleiotropic action reflects the diversity of its molecular interactions. Many of these interactions have been shown to be regulated by phosphorylation.

Combining methods to span different length scales

Abstract Molecular level researchers are very aware of requiring functional relevance even up to organism level and have explored this frontier by every means possible. How do we proceed from the molecular level, to the nanoscale level, and up to the cellular level of scale?
