The spread and invasion of many nonindigenous species in the ship’s ballast water around the world has been a hazard and threat to ecology, economy, and human health. The rapid and accurate detection of marine invasive species in ship’s ballast water is essential. This article is aimed at analysing ballast water quality by means of a changeable microfluidic chip detector thus comply with the D-...

Sustainable water management is one of the global grand challenges of our time. Tackling this challenge through corrective actions would require the participation of the general public, a public with sound awareness of the challenge and commitment. One such awareness raising intervention could be through the use of water symbolism and proverbs, targeted to particular society. Water has the diff...

The analysis of changes in water quality in a monitoring network system is important because the sources of pollution vary in time and space. This study utilized analysis of the water quality index calculation, hierarchical cluster analysis, and mapping. This was achieved by assessing the water quality parameters of the samples collected from Galma River in Zaria, Northwestern Nigeria in wet an...

There is great need and potential for traditional transaction support in a mobile computing environment. However, owing to the inherent limitations of mobile computing, we need to augment the well-developed techniques of Database Management Systems with new approaches. In this paper, we focus on the challenge of assuring data consistency. Our approach of localization is to reformulate global co...

Knowledge is nowadays an essential resource for modern organizations to support sustainable competitive advantage. Many authors point out that as knowledge is created, disseminated, and applied, it contributes to value creation within organizations by enhancing their capabilities to respond to pressures from the external environment. To acknowledge the critical role of knowledge in modern organ...

Water network partitioning (WNP) into supply clusters aims at improving management of the whole system and subsequent definition of District Meter Areas (DMAs), simplifying water budget and pressure management as well as the identification and reduction of water losses. This solution is a strategic option used by water utilities to control and operate their Water Distribution Networks (WDNs). T...

To improve the water resource management of the inland river basins of northwestern China, a Decision Support System (DSS) is developed to provide an operative computer platform for decision makers. The DSS is designed according to actual water resource management problems and is seamlessly integrated into a user-friendly interface implemented in the Visual C# programming language. The DSS comp...
