Stream Flow Model for a Coastal Stream in Egypt
The Coastal region north of Egypt contains many small streams known as Wadis which are considered the main water resources in that region. All the Wadis in the north coast of Egypt run...
Entropy as a Probability Concept in Energy-Gradient Distribution
The concept of entropy based on probability theory instead of thermodynamic principle has been applied to study the distribution of energy gradient along alluvial rivers. The formulas...
Fractional-Step Method for Two-Dimensional Estuarine Transport
The fractional-step method was used in this study to split the longitudinal advective transport term from the other terms in the two-dimensional, laterally-averaged equation for estuarine...
A Numerical Solution Technique for Incompressible Flow
Presented is a numerical solution technique which employs the explicit predictor-corrector scheme of R.W. MacCormack in solving the governing two-dimensional equations of motion on a staggered...
Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...
Stormwater Management by Utility Approach
Traditional methods of financing municipal stormwater operations and improvements through general city fund revenues has passed. A utility approach providing a continuous, uniform flow...
Identification of Automation Opportunities
Construction, although the world's largest industry, is also its most archaic. Most construction practices are very labor-intensive, with resulting impacts on safety, productivity,...
Generation of Native FE in Lunar Soil
Electron Spin Resonance (ESR) studies on lunar samples produced some unexpected results which led to recognition of the presence of abundant single-domain Feo...
Concrete Habitable Structure on the Moon
This paper presents construction methods for a concrete habitable structure on the Moon. The study was conducted on the assumption that a concrete manufacturing plant has already been...
A Methodology for Modeling Construction Requirements for a Manned Lunar Base
Before accurate modeling and planning of a manned lunar base can be accomplished, a methodology representing the construction-and-assembly process of lunar surface facilities must be developed....
Explosives Research for Lunar Applications: A Review
Experimental explosives research for lunar operations is reviewed. Each research project had a different objective and together their findings showed that using explosives on the moon...
The Expandable Platform as a Structure on the Moon
This discussion will show how the expandable platform, initially designed for earth, is translated for use on the moon, and how it answers a multitude of problems while it is used for...
Design of a Second Generation Lunar Base
We discuss the design of a permanent lunar base of 100 person size which may be able to expand to a base of about 500 person size. We present a preliminary design for a base concept which...
Homesteading Mars
The author gives serious study to setting up a permanent Martian base during the first or second manned Mars mission. The savings of fuel and equipment for the return trips might pay for...
Dynamic Analysis of the Joint Dominated Beam
A method is presented herein to determine the vibration modes of the Joint Dominated Beam. An example of a cantilever beam is selected for this purpose. The truss type beam is analysed...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Progressive Impact Damage Assessment in Composite Pressure Vessels
At the present time, advanced composites have been widely accepted as engineering materials. Analysis techniques for the response of composite materials and structures to static loads...
Telerobotics Design Issues for Space Construction
The efforts of a recent study aimed at identifying key issues and trade-offs associated with using a Flight Telerobotic Servicer (FTS) to aid in Space Station construction phase tasks...
Animation/Simulation for Construction Planning
The importance of a highly efficient schedule for space construction cannot be overestimated. A detailed scheduling process working closely with design data could reduce costs, minimize...
Robotic Influence in the Conceptual Design of Mechanical Systems in Space and Vice Versa: A Survey
A survey is presented of the methods of constructing structural elements in space by the application of robotic devices. Two fundamentally different approaches to the solution of robotic...
