In this paper, an observer-based fault detection and isolation (FDI) method for a biological wastewater treatment process (WWTP) is presented. The residual is generated utilizing an Extended Luenberger function observer. The FDI of a set of sensors faults is done by using a bank of Luenberger observers. The implementation of the proposed approach and the results obtained from its application to...

What actions can governments in developing countries take to make their economies more appealing to foreign investors? One increasingly prominent answer focuses on the effect of signing onto international economic agreements, showing that countries’ participation in investment and trade treaties is associated with greater inflow of FDI. Yet the nature of this empirical relationship remains uncl...

In this note we show how to test whether or not certain algebraic equations derived in the paper Fault Detection and Isolation for State Affine Systems, are solvable and to describe a solution method. Test and solution rely upon elementary linear algebraic techniques.

This paper addresses the problem of loudspeaker test. Two applications are investigated: loudspeaker manufacturing fault detection and maintenance. In order to comply with practical requirements, we propose a new, brief, nonstationary test signal. Recorded loudspeaker responses are processed using an improved time-frequency decision algorithm. The fault detection procedure is tested with real d...

This paper analyzes the impact of FDI on domestic firm entry and firm size distributions in 245 industries in the Czech Republic during 1994 to 2000. We find that larger foreign presence stimulates the entry of domestic firms within the same industry indicating the existence of positive horizontal spillovers from FDI. We also find evidence of significant vertical entry spillovers – FDI in downs...

The research in mechatronics focuses on the design and implementation of reliable, secure and economic systems. Our study is to modeling the operative part of a CNC machine using a bond graph approach with optimal placement of sensors in order to achieve a model for an integrated design of supervision. The proposed model allows a conception technically feasible and economically realizable to be...

This paper discusses the impact of foreign direct investment (FDI) on market entry and welfare in a model of two countries and two periods. In the first period, firms enter the market as national firms, in the second period, FDI is possible. The paper demonstrates that FDI reduces market entry because equilibrium profits in the second period decline with a decrease in the fixed cost of FDI. The...
