The Next Generation of Level Control
Water is an essential resource for everyday life, and thus having a way to store and distribute water is of critical importance. Water storage tanks have been designed to compensate for varying water demands during high and low peak periods, as well as for firefighting, power outages and other emergency demands. There are many ways to store water in a distribution system, but what it all ...

An Enforcement-Coalition Model: Fishermen and Authorities Forming Coalitions
The paper sets up a four-stage enforcement model of fish quotas. The purpose of the paper is to show how the level of enforcement set by the authorities affects the way fishermen form coalitions. We show that a high level of control effort yields less co-operation among fishermen, while in the case of low control effort, coalitions are somewhat self-enforcing. The paper further discusses how the ...

Stable design of Takagi-Sugeno fuzzy controllers for a laboratory three-tank system
This paper suggests a stable design approach dedicated to the Takagi-Sugeno fuzzy controllers for the water-level control of a laboratory three-tank system. The design approach is based on a simplified application of LaSalle's global invariant set theorem. An original stability analysis theorem offers sufficient inequality-type stability conditions that enable the controller design and tuning. ...

Product modularity, information structures and the diffusion of innovation
This paper explores how the product design information structure affects innovation types and levels of innovation diffusion. By taking a narrower definition of information structures than previous usages, the author seeks to clarify how specific dimensions of this type of knowledge link with a range of innovation variables in a modular product setting. It is proposed that the type of product ...

Performance evaluation and risk management for industrial systems by using fuzzy controller
In this work, we present a synthesis methodology of a multivariable fuzzy controller for the control of a multi-motor system (MMS) that can be intended for winding and unwinding controlled transport processes. The simulation results show that the integration of the fuzzy multivariable controller brought good performances compared to the multivariable PI-structure controller, and a clear ...

Study of banking sector design from risk perspective to minimise social costs
A comprehensive review of the US banking sector design is currently underway with debates among bankers, trade, consumer groups and regulatory agencies on pricing, The Federal Deposit Insurance Corporation (FDIC) bank insurance fund maintenance and coverage levels for new deposit insurance initiative. A macro design framework is proposed as an input to planned improvements. The objective of the ...

Water bottling plant chooses Greyline for level control - Case Study
Culligan were able to double up level monitoring of two tanks with one instrument because pairs of identical-sized tanks were interconnected with a 2” pipe near their base. The Greyline SLT32 was calibrated to display the combined volume of both tanks. This function worked with a two vertical tanks as well as a pair of horizontal round tanks where the SLT32’s HRT round tank volume ...

Automatic control of pollutant on a shallow river using surface water systems: application to the Ebro River
In this paper, the problem of automatic control of pollutant on a shallow river using surface water systems is addressed using a benchmark test case based in the Ebro River. The Ebro River presents flooding episodes in the city of Zaragoza in Spring when snow melts in the Pyrenees. To avoid flooding and high pollutant levels in living areas, some lands outside the city are prepared to be ...

Stepwise innovation adoption: a neglected concept in innovation research
Most innovation researchers tend to consider innovation adoption as a binary process, implying that companies have either adopted an innovation or not. In this paper we focus on e-commerce as an innovation that can be adopted stepwise. We distinguish between two levels of e-commerce, basic and advanced. Following Rogers' (1995) innovation adoption model, we investigate the differences between ...
