The purpose of this paper is to propose an overview of the knowledge virtual enterprise model, where the virtual enterprise vision is extended with knowledge-based assets in order to provide an agreement model to support the interoperability among…
-
The unstable nature of wireless communication makes it hard to maintain a reliable network organization in Wireless Sensor Networks (WSNs). Therefore, network organization repair scheme is highly required for reliability. Because of the high energy…

Is the name of a remote sensing project established in the first phase of a future commercial SAR and hyperspectral scanner satellite mission. Research work in the past has shown the commercial potential of combined SAR and hyperspectral scanner…
-
Since the beginning of 1994 the Institut of the German Aerospace Center (DLR) has been operating an experimental airborne SAR E-SAR with a P-band radar front-end. The microstrip patch array antenna allows a signal bandwidth of slightly more than 10%…
-
In the new learning environments, built width digital technologies, the need to promote quality of education resources, commonly known as Learning Objects, which can support formal and informal distance learning, emerge as one of the biggest…
-
This paper presents, a domain independent tool, developed in JAVA that automates the process of extraction, analysis and classification of events from textual requirements, expressed in English as a natural language. A study on various existing…
-
The paper presents an innovative approach for scheduling network messages with real time dynamic algorithms. The solution described takes advantage of the increased network utilization allowed by dynamic scheduling methods and bounds and at the same…
-
Data transfer in distributed environment is prone to frequent failures resulting from back-end system level problems, like connectivity failure which is technically untraceable by users.Error messages are not logged efficiently, and sometimes are…
-
The Global Data Computation problem consists of providing each process with the same vector (with one entry per process) such that each entry is filled by a value provided by the corresponding process. This paper presents a protocol that solves this…

Everyone would admit that disaster early warning is more important than later treatment and damage repair. If an effective tsunami early warning system had been in place in the Indian Ocean region on 26 December 2004, thousands of lives would have…
-
In this paper a remote sensing based approach to assess potential anthropogenic stress to coral reefs worldwide is presented. Three reef stressors are analyzed using nighttime lights data derived from the Defense Meteorological Satellite Program…
-
A group of forested nations agreed upon a set of criteria and indicators to measure the sustainable development of forests. Of the 83 indicators, remote sensing could measure in whole or in part about 25 indicators. Moreover, such measurements could…
-
This paper presents a system to integrate digital elevation model (DEM) enhancement and Earth Observation (EO) image analysis for realistic three-dimensional (3-D) rendering applications. There is an increasing interest in interferometric synthetic…
-
MODIS data are compared to NOAA AVHRR for derivation of bio-physical parameters in the semi-arid Senegal, West Africa. The dynamic range of the two MODIS Vegetation Indices CVI and EVI is generally much larger than for the corresponding NOAA AVHRR…
-
Rapid damage assessment after natural disasters (e.g., earthquakes) and violent conflicts (e.g., war-related destruction) is crucial for initiating effective emergency response actions. Remote-sensing satellites equipped with very high spatial…
-
Seasonal coastal upwelling in the U.S. Mid-Atlantic region occurs normally during the summer months because of generally northward alongshore wind episodes. These winds force an Ekman offshore surface flow over the inner continental shelf. Colder…
-
We have designed and tested a new, inexpensive, easy-to-make and easy-to-use calibration standard for atomic force microscopy (AFM) lateral force measurements. This new standard simply consists of a small glass fiber of known dimensions and Young's…
-
We have investigated a simple yet powerful method for making sharp scanning tunneling microscopy tips of Pt/Ir. It consists of three electrochemical polish/etch steps, not requiring any special micropolishing. The tips, as seen by high-resolution…
