3D CAD Modeling and Graphical Simulation of Mobile Cranes
This paper describes the research performed to lay a foundation for developing a graphical simulation system which can be used in the planning of heavy lifts using mobile cranes. Mobile...

Automatic, Remote, Multiplexed Geotechnical Measurements with Time Domain Reflectometry (TDR)
Time Domain Reflectometry (TDR) has been employed successfully in geotechnical applications such as monitoring of rock mass deformation in a variety of geometries; however, required operation...

Ice Accumulation Rate and the Geometry of Ice Jams in River Bends
Experiments on development of ice jams in river bends were performed in a 2.60-m-wide bend flume with a sand bed and 5-mm-diameter plastic beads simulating ice particles. The ice particles...

Step Pool Geometry and Flow Characteristics in Low-Sediment-Storage Channel Beds
Data from two small ephemeral streams in Israel indicate that step pool geometry in bedrock channels is similar, in its salient features, to that in alluvial channels. For steep (>0.10)...

Equilibrium Geometry of Channels with Cohesive Banks
An optimization model is used to assess the stability of gravel-bed rivers with cohesive channel banks and to determine the effect of the bank stability on the equilibrium hydraulic geometry....

Adaptability of Translation-Grid Shells

Conceptual Design and Characteristics of A Dual-Arm Cam-Lock Manipulator
Recent developments in the area of smart structures indicate that variable geometry/stiffness truss network is of fundamental importance in designing smart transformable structures and...

Prisms and Antiprisms
Prisms form a group of mathematical figures, that have found widespread application in many disciplines, but especially in architecture and in building structures. They have two identical...

Streamflow Related to Channel Geometry in Northern New England
Channel geometry measurements can be used to estimate various streamflow characteristics at ungaged stream locations. Channel cross section dimensions and sediment size distributions were...

Space Frames and Polyhedra
Polyhedra are easy to build and they can be useful as architectural matrices. Relatively small polyhedra can be built as faceted structures; very large ones can be built with space frames....

Tensegrity Structures: Filling the Gap Between Art and Science
Underlining the role of structuralism in contemporary architecture this paper addresses the application of structural morphology in the context of an educational experience. Focussing...

Numerical Simulations of the CCS under the Joint Effects of Coastal Geometry and Surface Forcing
Using the S-Coordinate Rutgers University Model (SCRUM) of Song and Haidvogel(1993), a coupled coastal (86 m depth) and deep ocean (4600 m depth) California Coastal region has been investigated...

Glass-covered Lightweight Spatial Structures
The double curved reticulated spatial structure with triangular mesh is the most favorable basis for a translucent roof. But this structure, especially is directly glazed without intermediate...

Hyper-Geodesic Structures: Excerpts from a Visual Catalog
A class of hyper-geodesic surface structures is presented. The surfaces of known polygons, polyhedra, plane and space tessellations, higher dimensional polytopes can be subdivided into...

Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...

A Study on Buckling Characteristics of Single-Layer Latticed Domes with the Initial Geometrical Imperfection

Evolutionary Methods for Synthesis of Truss Topology

Effect of Pier Geometry on Scour in Graded Gravels
This paper summarizes the results of laboratory tests performed on clear water scour around circular and rectangular cross section bridge piers, embedded in a non-uniform coarse sediment...

Applicability of Pseudo-force method to Highly Nonlinear Dynamic Problems
This paper deals with solution of nonlinear dynamic problems using Pseudo-force method. A solution algorithm involving Pseudo-force method is presented. The objective is to investigate...

Determination of Geometry and Stress Distribution of an Optimal Stable Channel
A numerical model which determines the geometry of a threshold channel was recently developed (Diplas and Vigilar, 1992). This is important in the design of irrigation canals, channelization...
