State and Resource Based Construction Process Simulation
Stroboscope is a programming language for construction process simulation. The programming language provides access to the state of the simulation and to the properties of resources. It...

How Many Observation Wells Does it Take to Find a Groundwater Contamination Plume?
A Bayesian data worth framework is developed to balance the benefits and costs of data collection. In addition to Bayesian decision analysis, tools from Monte Carlo simulation, numerical...

Application of a Geographic Information System to Evaluate Environmental Hazards
The development of a Geographic Information System (GIS) application to evaluate potential environmental hazards within the Bushkill watershed in Northampton County, Pennsylvania, is described...

Computerized Facility Information Management Systems
The paper describes a computerized information system that can be used in place of the traditional operations and maintenance manual used by facilities personnel. Plant operations and...

A Decision Support System for Nonpoint Source Pollution Management Using a Distributed Model-GIS-DBMS Linkage
Methods were developed for directly linking the distributed parameter model, AGNPS with a GIS and a relational database management system (RDBMS) to investigate a nonpoint source pollution...

Heuristic Knowledge-base Approach to Runoff Estimation in Midwestern States Using a SCS Curve Number Method
The applications of the Knowledge-Based engineering has emerged as a potential technique for incorporating human expertise and some degree of intelligent judgment into decision-supporting...

Quality Management of Earthwork Using Knowledge-based Systems
Earthwork is an integral part of many construction projects. It involves cleaning of the site, loading and spreading of soil, and soil compaction and leveling. Heterogeneous orientation...

A Goal Driven Approach to Discrete Event Simulation
Discrete event simulation is getting more attention as a tool for allocating construction resources. However, its usage is limited because it requires intensive knowledge in conducting...

Progression of Computer Applications in Water Supply and Distribution Systems
Over the last two decades, computer applications in water supply and distribution systems have advanced rapidly from the stand-alone applications in system modeling to the integrated platform...

Use of Expert Systems in Selecting Equilibrium Isotherms of Organic Compound Adsorption on Activated Carbon
An outline of an Expert System (ES) that aids in selecting adsorption isotherms is presented. Such an ES provides an efficient technique for screening the present literature. The ES helps...

Utilizing Mathcad for Hydraulic Design of Stormwater Pump Stations
This paper describes how the software Mathcad was used for hydraulic design of three pump stations (i.e. select pumps and size forcemains). The pump stations are part of a complete stormwater...

A Technique to Perform Coupled Consolidation Analysis Using Two Independent Softwares
The consolidation of soils involves two interdependent processes. These are fluid (air and water) flows and the deformation of the soil structure. The two processes tend to be treated...

An Artificial Neural Network Approach to Allocating Construction Resources
This paper presents an approach to alleviate the problem of depending upon human expert in allocating construction resources. This approach is using artificial neural networks to capture...

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...

Circulation and Flushing in Casco Bay, Maine
A modified 3-D hydrodynamic numerical model MECCA (Model for Estuarine and Coastal Circulation Assessment; Hess, 1989) has been applied to Casco Bay, Maine, with a horizontal resolution...

Modeling Initial Mixing of Ocean Wastewater Discharges to Develop Toxic Effluent Limitations
The UM model, released by USEPA in 1992, was utilized to simulate the initial mixing of a discharge to the Atlantic Ocean near Ocean City, New Jersey. The study included field verification...

Three-dimensional Modeling for Improving Construction Process Performance
This paper presents experimentation regarding a model for deciding the optimum number of resources that should be allocated to a project. Measures of task and process flexibility are used...

Computerized Building Settlement Analyses for a Contaminated Groundwater Remediation Project
The use of spreadsheets is becoming ever more popular in the practice of civil engineering. Engineers are able to use this tool to meet deadlines which were once insurmountable. This paper...

Optimal Markup Policy in Sequential Competitive Bidding
Construction firms encounter resource constrains in their business operations. However, current competitive bidding models fail to consider the impact of a firm's constrained resources...

The Use of SCADA for Real-time Calculation and Monitoring for CT Compliance at the Ralph D. Bollman Water Treatment Plant
The contra Costa Water District (CCWD) of Concord, CA was formed in 1935 under the authority of the State Water Code. CCWD purchases its water supply from the Central Valley Project (CVP),...
