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...

Fast Monte Carlo Simulations and Safety Index Checking
This paper presents recent techniques which require a small number of simulations to assess the structural reliability. They combine both the concept of importance zones in the random...

SQP Methods for Inverse Airfoil Design
We consider inverse design problems of systems governed by suitable discretizations of a boundary value problem (BVP). We present and examine a Sequential Quadratic Programming (SQP) method...

Generalized Optimal Active Control with Embedded and Half-space Soil-Structure Interaction
The paper presents an optimal active control algorithm with soil-structure interaction for seismic response. By using an intelligent device in the feedback gain matrix, the algorithm can...

Engineering, Construction, and Operations in Space IV
This proceedings, Engineering, Construction and Operations in Space IV, consists of over 155 papers presented at Space 94, the Fourth International...

Demand/Supply Relationship in Transportation Network Design Problems: A Genetic Algorithm Approach
The cumulative genetic algorithm (CGA) has its significant advantages over the heuristic algorithms in dealing with transportation network design problems. Using CGA, the entire solution...

Intelligent Construction Planning
The intelligent construction planning is a stage of automated building realization process. The building is defined in the design stage by its spaces and functional systems. The automated...

Alternative Decisions for Space-Based Scheduling in Multi-Story Projects
SCaRC (Space-Based and Resource-Based) is a prototype knowledge-based scheduling system that acknowledges work space as a scheduling constraint. The SCaRC system comprises different scheduling...

Time-Space Tradeoff Strategies for Space-Schedule Construction
Space availability on a construction site can have a major impact on the efficiency and constructability of a project. Especially when space is limited, tradeoffs between activity sequencing,...

Development of a Visual Method to Track the Movement of Hydrogen Bubbles in a Laboratory Flume
The current study proposes a visual method for tracking the hydrogen bubbles position with time in a 2-D space. The experiment is filmed from above with a video camera. The obtained movie...

Malaysia's Twins: High-Rise, High Strength
U.S. firms, following the market for new skyscrapers to Asia, are involved in design and construction of twin office towers in the commercial heart of Kuala Lumpur, Malaysia that will...

The Variability of Large Alluvial Rivers
Written by river engineers and earth scientists who are experts in river morphology, dynamics, and control, The Variability of Large Alluvial Rivers...

Space-Frame Pyramid
The world's largest space frame pyramid, completed at California State University in Long Beach in late 1994, proved to be a lighter weight and more economical alternative...

Alternative Habitat Concepts for the First Lunar Outpost
The First Lunar Outpost (FLO) Study was a NASA-wide effort to define systems for a near-term, low cost return to the Moon. The FLO habitat must support four crew on the lunar surface for...

Improving Development Characteristics of Reinforcing Bars
Prepared by the Civil Engineering Research Foundation. Sponsored by CERF, This report describes the development and implications of a new concrete...

Bridge to the Future
The experimental Roize Bridge, near Grenoble, France, features an innovative composite space truss and unique modular construction methods for efficiency and economy. The Roize Bridge...

Machine-Friendly Facility
Cargo facility automation makes more efficient use of space, reduces labor and speeds operations. These are critical factors at New York's John F. Kennedy International Airport—currently...

A Decision Support System for the Operation of Joint-Use Parking
A prototype decision support system (DSS) developed for streamlining the operation of a joint-use parking program is discussed. The DSS involves a combined usage of geographic information...
