Proceedings of the International Conference on Harbor, Maritime and Multimodal Logistics Modeling & Simulation, HMS 2009 ISBN 978-84-692-5416-5 146 ABSTRACT The Navigation System Simulation (NaSS) suite of tools has been developed by the Institute for Water Resources of the U.S. Army Corps of Engineers (Corps), as part of the Navigation Technologies Research Program. NaSS is composed of two pri...

Procurement contracts are often renegotiated because of changes that are required after their execution. Using highway paving contracts we show that renegotiation imposes significant adaptation costs. Reduced form regressions suggest that bidders respond strategically to contractual incompleteness and that adaptation costs are an important determinant of their bids. A structural empirical model...

In an effort to evaluate socio-political instability, we studied the relationship between dynamic order, socio-political upheavals and sustainability in nation states. Estimating the degree of dynamic order inherent in the socio-political regime of various countries throughout theworld involved applying Fisher information theory to data from the Political Instability Task Force database. Fisher...

Common Reed (Phragmites australis) is a frequent component of inland and coastal wetlands in temperate zones worldwide. Ongoing environmental changes have resulted in the decline of this species in many areas and invasive expansion in others. In the Gippsland Lakes coastal waterway system in south-eastern Australia, increasing salinity is thought to have contributed to the loss of fringing P. a...

Background and Objectives: Knowledge Management (KM) has emerged as a pathway towards competitive advantage in current complex industrial environment. The aim of the present study was to explore the relationship between KM effectiveness and various organizational factors including social interactions (trust, communication and coordination), infrastructure factors (structure, information technol...

Waterway degradation in agricultural settings is caused by direct and diffuse sources of pollution. Waterway fencing focuses on reducing direct faecal contamination, but the extent to which it reduces overland surface runoff of pathogens is unknown. This study evaluated the potential of four riparian treatments to reduce Giardia in saturation excess surface runoff entering the waterway. Treatme...

Abstract The low-lying Pearl River Delta in South China is subject to severe flood threats due watershed floods, sea level rise, and storm surges. It still unknown what extent how far inland surges rise impact the extreme stages. This study investigated coupling effect of discharge surge on stages by using site observations simulations generated Hydrologic Engineering Center-River Analysis Syst...

The fast power adaptation is essential for WCDMA based mobile radio networks, as 3G UMTS. Although the first version of UMTS has been released in 1999 (Release 99) evolution was not finished yet. Quality of Service (QoS) and user data rate (e.g. HSDPA and HSUPA) are continuously increasing from release to release. Even though link adaptation frequency (1500 times per second) seems to be enough ...
