Using Forecasts to Improve Reservoir Operations
This review considers methodologies that have or can be employed to incorporate streamflow forecasts into reservoir policies and operating decisions. These include the use of streamflow...
Stochastic Reservoir Operation under Drought with Fuzzy Objectives
Biobjective reservoir operation under drought conditions is investigated using stochastic dynamic programming. As both objectives (irrigation water supply, water quality) can only be defined...
Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...
Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...
The Impact of Global Warming on Water Resources: Overview and Implications for Coastal California
In the past two years, impressive evidence has accumulated that global warming is occurring and is related to the increase in greenhouse gasses. The impact of the warming process on water...
Optimal State Feedback Estimation in Groundwater: Application to Leaky Aquifers
The problem of groundwater flow in leaky aquifer is looked at from a stochastic point of view. Optimal estimation of hydraulic heads are achieved using Kalman filtering. The Kalman filtering...
The Application of AI in Highway CAD System
In a conventional CAD System, the process for solving a certain particular engineering problem is fixed stationary in the program. As a result, the program is often modified to fit different...
A Stochastic Cost Engineering System (SCENS) Applied to Estimating and Tendering for Bill of Quantities Contracts
In many countries, contracts based on bill of quantities are very common in construction industry. Although estimating and tendering are overwhelmed by uncertainties, the common practice...
3D Template of Human Figure for CG Animation in Design
It has become commonplace to use computer graphics (CG) animation in architectural and landscape design. Historically, CG animation has been employed primarily as one of many presentation...
A Work Packaging Process Model for Petrochemical Plant Piping Construction
This paper presents a model for the current work packaging process for petrochemical plant piping construction. The basic foundation of the model is formed by identifying major decision...
What is Multimedia Computing?
Computing changed dramatically in the 1980s. The emergence of the personal computer desktop as a standard has spawned the existence of an incredible 60 million personal computers worldwide....
Filing of Construction Photos Linked with Database
In order to raise the added value of construction information, a filing system of construction pictures is built up and is used theoretically linked with a database. Here, conditions set...
Maintaining Engineering Drawings in the '90s
With the technologies available today, it is possible to begin a scanning system at a rather small or limited scale - and still realize a quantifiable return on investment. In the 90's,...
A Stochastic Cost Engineering System (SCENS) Applied to Estimating and Tendering for Bill of Quantities Contracts
In many countries, contracts based on bill of quantities are very common in construction industry. Although estimating and tendering are overwhelmed by uncertainties, the common practice...
Development of Differential Growth Method for Automated Vehicle Recognition
The purpose of this study is to improve a system which enables automatic recognition of vehicles from video images using image processing system. Basic methodology is a subtracting operation...
The Application of Gauss Numerical Integration Method in Arch Dam Trial-load Method Program
The characteristics of Gauss Numerical Integration Method are the unequal distance between nodes and fairly high accuracy. When the number of nodes is n, the algebraic accuracy can be...
Model-Based and Interactive Planning for Predictive Plant Maintenance Management
Maintenance of process in power plants represents about 30% of the operating cost of these plants, including the cost of repair labor, materials and out side services but not the cost...
Invasion of the Zebra Mussels
At first glance, the zebra mussel looked like doom for freshwater users in the Great Lakes: small, hardy, incredibly prolific European mollusks with an affection for freshwater intakes...
Transient Performance Model of Asphalt Pavement Deterioration and its Application to Repair Management
The Japanese Ministry of construction has conducted surveys of the pavement surface condition of national highways. This paper describes the evaluation of the performance of asphalt pavement...
An Overview of Markovian Models for Bridge Management Systems
The typical infrastructure maintenance decision-making environment involves multiples objectives, uncertainty, and dynamics of the most commonly used infrastructure models, which captures...
