Computer simulations of coastal dynamics for design of breakwater layout.
Abstract Computer simulation of coastal dynamics provides very useful tool for designing the layout of breakwater to ascertain the feasibility of the port development. Most of the coastal phenomena such as wave propagation, tidal hydrodynamics, sediment transport etc., which are important for designing the port layout, can...

A numerical modeling of uncertain parameters associated to a transport model of radionuclides in porous media.
ABSTRACT With the importance devoted to the protection of the natural environment, the computer simulation of contaminant transport in groundwater has acquired recognized importance as a tool for the prediction of future. In this context, we present a random fields generator for building a Monte Carlo model...

Childhood and teen overweight is linked to adult CHD.
Childhood and adolescent overweight are associated with an increased risk of coronary heart disease in young and middle-aged adults, researchers in two separate studies reported. Given the current surge in pediatric weight gain worldwide, these findings indicate that there will be substantial rises in CHD-related morbidity and...

Dynamic behavior of mobile air-conditioning systems.
Passenger cars and light trucks consume 80% of the total oil imported by the United States. Mobile air-conditioning systems (MACs) increase vehicle fuel consumption and exhaust gas emissions. They operate most of the time in a transient state. To investigate the dynamic behavior of a typical R-134a MAC, the...

Icy invention.
[ILLUSTRATION OMITTED] All ice-skaters should thank Finland. That is a country in Europe. Scientists recently discovered that people who lived in Finland in ancient, or long-ago, times were the first to create and use ice skates. They made the first ice skates about 5,000 years ago. Instead...

Improbability drive: focus on rare actions speeds chemical simulations.
In The Hitchhiker's Guide to the Galaxy, the book by Douglas Adams, a machine made interstellar travel possible by nudging nature toward extremely improbable, but not impossible, events. A new computer-simulation technique promises to calculate chemical-reaction rates 20 times as fast as before by focusing on chains of events...

Prehistoric trade between Ecuador and West Mexico: a computer simulation of coastal voyages.
A variety of evidence shows that contact occurred between Ecuador and West Mexico (Figure 1) from 400 BC to the sixteenth century, even if such contact was not necessarily continuous. The evidence comes from metallurgy (Hosler 1988; Hosler et al. 1990), shaft tombs and mortuary offerings (Kan et al....

The importance of human productivity to air-conditioning control in office environments.
In this paper, the importance of human productivity to air-conditioning control in office environments is discussed. A case study was conducted to compare the performance of two control methods--conventional setpoint control and predicted-mean-vote-based (PMV-based) control--in an office environment. The comparison was based on three factors--human comfort, energy consumption, and...

Measured and predicted thermal performance of a residential basement.
This paper describes the measurement of ground and internal wall temperatures, local surface heat fluxes on the basement walls and floor, and overall heat losses for a concrete wall basement. The heat fluxes were measured with heat flux meters and mimic boxes. Daily and seasonal measured performances are displayed....
