Berlin's Big Dig
As the first of many major development projects for the new Berlin, the DM 1.5 billion FriedrichstadtPassengen project is the largest private construction investment in Berlin's...
A Second Life for Dredged Material
To ensure safe, navigable waters, rivers and waterways must be dredged. Dredging in the U.S. requires long-term alternatives for placement of more than 300 million cu yds of dredged material...
Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
A Texas-Sized SSO Solution
Houston is under the gun to control chronic overflows in its sanitary-sewer-collection system--a wet-weather problem that has plagued the city for years. For a problem this massive, the...

Reliability and Response Control of R/C Buildings
A damage model is summarized for the assessment of seismic damage of reinforced concrete structures. The model is to evaluate specific buildings that were damaged in Mexico City during...
I.P.L. Space Trusses: Structural Performance and Analysis
The utilization of the fast working massively parallel computers in solving intense numerical problems, in the field of structural engineering left disappointed many of practical engineers....
Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
Depressing Traffic Top-Down
Top down construction will permit the City and County of Denver to maintain traffic at two congested intersections while a tunnel is driven below them. The project, which will carry Speer...
Autonomous Navigation for Structured Exterior Environments
The Telemanaged Mobile Security Station (TMSS) was developed at Sandia National Laboratories to investigate the role of mobile robotics in exterior perimeter security systems. A major...
Intelligent Excavator Control for a Lunar Mining System
The benefits of utilizing local planetary resources are a large reduction in the cost of lifting materials from the earth's surface into earth orbit. Since the moon is one of the closest...
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...
Generalized Object Control and Assembly for Space Robots
This paper presents a Generalized Object Control framework which subsumes Unified Motion/Force Control and Object Impedance Control. Under this framework new forms of assembly primitives...
Drivetrain Design, Incorporating Redundancy, for an Autonomous Walking Robot
An often overlooked, though critical, component of a mobile robot is the drivetrain. To achieve the ambitious programmatic goals of an extra-terrestrial, planetary robotic explorer, a...
An Intelligent Robotic Vehicle for Lunar/Martian Applications
This paper describes the research effort being undertaken at UA/NASA Space Engineering Research Center (SERC) towards a general-purpose intelligent robotic vehicle system (IRVS) for Lunar...
The Kinematic Design of a Robotic Large Space Structure Construction Service
Researchers at the University of Maryland's Robotics Research Lab are applying a kinematic rapid proto-typing methodology to the development of a commercial robotics service for the construction...
A Novel Gravity Compensation System for Space Robots
Realistic experimental investigation of the behavior of space robots requires simulation on earth of the micro-gravity environment existing in space. This is particularly true due to the...
Real-Time Control for a Robotic Rebar Bender
Job conditions and variability in the properties of the stock material combine in a rebar bending operation to create a challenging environment for a robotic bender. This paper reports...
