Construction Technology/Method Identification and Selection System
The proliferation of construction technology and the characteristics of technology information, such as complexity, interdependency, etc., pose the need for a well-organized technology...
Radio Frequency Data Communication Applications in the Construction Industry
Construction operations produce substantial amounts of data resulting in seemingly growing amounts of paperwork for construction personnel. Not much can be done to diminish the amount...
Kinematics and Trajectory Planning for Robotic Excavation
One of the high volume and repetitive construction operations at the construction site is the excavation of soil. Automation of the excavation work requires a robotic system that is able...
Going Where No Man Can Go
After the 1979 accident at Three Mile Island Unit 2 in Harrisburg, Pa., some areas of the reactor plant were too contaminated for workers to survey, much less clean. The article describes...
Airborne Remote Sensing of Breaking Waves with Implications for Gas Exchange
It is shown that airborne remote sensing can potentially relate gas mixing effects within a temporally evolving breaking wave to relectivity changes, and can identify the intensity of...
Earthquake Evaluation of a Substation Network
The impact of the occurrence of a large, damaging earthquake on a regional electric power system is a function of the geographical distribution of strong shaking, the vulnerability of...
Two Decades of Communications Systems Seismic Protection Improvements
Telecommunications systems in North America have gone through significant technology changes in the past twenty years. The electro-mechanical switching equipment has been replaced by electronic...
Access Floor Response Spectra for Equipment Line-Ups in Telecommunications Central Offices
Modern telecommunications central offices very often utilize access floors to support equipment line-ups. An analytical study was carried out to study the seismic response of equipment...
Telecommunications Facilities Earthquake Readiness Since San Fernando
The vertical rack architecture of telecommunication offices showed some weaknesses during the San Fernando earthquake in 1970. Efforts have been made since then to improve performance...
Analysis of Roadside Equipment and Central Facilities for Innovative Driver Information and Traffic Control Systems
Following a top down analysis of a selected set of innovative RTI functions, we identify in this paper the requirements and characteristics of the roadside equipment and central installations...
Assessment of the Sate-of-the-Art of Robotics Applications in Highway Construction and Maintenance
Automation and robotization in highway construction and maintenance are currently under active development in the United States and other countries around the world. Although road construction...
Perception and Control for Automated Pavement Crack Sealing
Pavement maintenance is a major transportation engineering activity that has seen only partial mechanization and virtually no automation. Crack sealing is a typical maintenance task in...
Design Considerations for Automated Pavement Crack Sealing Machinery
The purpose of this paper is to discuss the numerous considerations for designing automated machinery for the sealing of cracks in pavement. Operational requirements are presented and...
Contact-Free IC Cards for New Railway Ticket Systems
Two types of smart cards which can communicate with an automatic gate machine without contact are developed. The first one uses medium wave radio as communication media. The microprocessor...
Space Saving Dry-Stack Boat Storage Facility
Given sales and demographic data of recreational boating, urban dry-stack marinas will be the trend of the future where there is no room to expand. This paper describes a modern automated...

A Seismic PRA Procedure in Japan and its Application to a Building Performance Safety Estimation: Part 2. Fragility Analysis
In this paper, a practical seismic fragility evaluation method for structure and equipment systems is proposed. Structural and equipment failures are considered here, reflecting detailed...
Responses of a Secondary System and Its Supporting Hysteretic Structure to Seismic Excitations
We consider an N-story building that supports 1-degree-of-freedom equipment on one of the floors, and examine both the building's and the equipment's responses...
An Investigation of Live Loads on Concrete Structures During Construction
Slab formwork live loads include the weight of equipment, construction material storage loads, and impact loads when placing the concrete. In this paper material and equipment loads are...
On Reliability of Mechanical Logics and Its Application
Recently, most of logical circuits are understood to consist of electrical components and wiring, however, we are still using various types of mechanical logics at the end of the safety-related...
