Seismic Vulnerability of Residential Structures in Nicaragua
(2009)
In recent times, many parts of the world have seen a trend of increased construction with reinforced concrete and masonry block systems. These systems can provide excellent seismic resistance when they are designed by an ...
Fracturing of Layered Reservoir Rocks
(2009)
The development of fractures in rock layers reflects a history of complex, non-linear, time-dependent mechanical processes. The processes strongly depend on the rock rheology, particularly the behavior during progressive ...
Biosurfactants: Characterization, Microemulsion Formation and Potential Applications
(2009)
Biosurfactants, which are produced from microorganisms, have become of interest due to their non-toxic nature, their biodegradability and their production from renewable resources. Research has evaluated the use of ...
Discovering Interesting Patterns and Associations in Data Streams
(2009)
A data stream is a sequence of items that arrive in a timely order. Different from data in traditional static databases, data streams are continuous, unbounded, usually come with high speed, and have a data value distribution ...
Turbulent heat transport in plane channel flow and plane Couette flow using direct numerical simulation in conjunction with Lagrangian scalar tracking
(2009)
Turbulent flows in plane channel and plane Couette are investigated using a direct numerical simulation in conjunction with Lagrangian scalar tracking of trajectories of thermal markers. The flow is for an incompressible ...
On Certain Towers of Extensions by Antiderivatives
(2009)
Let F be a characteristic zero
Feasibility of a Cognitive Extension to Existing 802.11b Wireless Devices
(2009)
Cognitive radio presents a means of altering the communication method of a wireless device based on channel conditions and the intended receiving device. However, the design of such a radio is very complicated as it must ...
A Regional Modeling Study Of Climate Change Impacts On Warm-Season Precipitation In The U.S.
(2009)
Changes in the character of precipitation have already been observed over much of the United States. In a warming climate, the impacts of these changes will likely be felt most strongly through changes in the intensity and ...
Internal and External Validity: Two Faces of the Same Coin
(2009)
Internal and external validities have been traditionally presented as two different topics. The present paper brings them together by showing how the two are related when the samples have been previously selected on a ...
Demographic Characteristics that Influence Leadership, Communication, and Citizenship Behaviors in a Military Hospital
(2009)
This field study involves a bottom-up assessment of the quality of leadership, communication, and organizational citizenship in a military hospital, as reported by employees that are directly involved with operations that ...
