In this report, we propose a tracking method that tracks a water level as a line from a video sequence. This method targets the use in a river surveillance and alarm system. In our proposed method, a line tracking problem is transformed to a point tracking problem by using Hough transformation and the point is tracked with Condensation algorithm. Our proposed method is examined by comparing wit...

The paper analyzes the impact of a two-level game for water allocations. For a model with two domestic groups and two countries, and with both domestic and international negotiations, Nash bargaining theory is used to derive several propositions on the consequences of different bargaining rules for water allocations. The effect on international negotiations of the ability to commit to having do...

This paper develops a model of ‘governance’ as an aid for comparing such governance structures and applies these to a particular policy arena: policies on the protection of groundwater and on drinking water quality in the Netherlands and Florida. The research questions examined by this paper are: 1. Which elements make up a governance structure? 2. In what ways do these elements influence each ...

Abstract This report proposes a design method of a digital filter to detect running water region in video signal. As a result of applying this filter, the water level of a river is automatically detected as a boundary between the land region and the water region. Conventional approaches have used the edge detector "vertically" to extract a horizontal line as running water surface. The frame "su...

Hydraulic fracturing is an effective technique for increasing the productivity of wells producing from low permeability formations. Tracer fracture monitoring technique is near-wellbore zone frctures direct test method that can monitor the height and width of hydraulic fractures in the near-wellbore section. ZeroWash Tracer uses a medium strength ceramic proppant which is mainly used in fractur...

The recent discovery of high levels of lead in the drinking water in Flint, Michigan, and in several urban school districts has focused public attention on the potential harms of blood lead, particularly for children’s development. While child blood lead levels (BLLs) have declined dramatically over the past several decades, estimates suggest that there are still a half a million preschoolaged ...
