Polarization Mode Dispersion (PMD) is considered to be one of the most serious obstacles in the high speed optical telecommunication systems. This thesis focuses on a deterministic approach to both compensation and emulation of PMD. Most PMD compensation schemes in the literature rely on feedback loops to search for the optimum control parameters in the compensator. These schemes often suffer f...

Completeness of the wave operators has been proven for a family of random Schrödinger operators with sparse potentials in the recent paper [17], using a probabilistic approach. As mentioned at Voss, a deterministic result in this direction can also be derived from a Jakšić–Last criterion of completeness [7] and Fredholm’s theorem. We present this approach.

The issue of knowledge representation and the method of inferring decision rules are of fundamental nature in the design of intelligent systems. When knowledge of the system is sufficient and precise (without uncertainty), many problems in artificial intelligence can be successfully modelled by techniques such as first order logic (Kowalski, 1979; Barr & Feigenbanm, 1981). For instance, the log...

This abstract presents the initial results of exploring the notion of non-determinism in representing nursing intuition via type-2 fuzzy sets.

This paper presents a multi-objective model for location-transportation problem under uncertainty that has been developed to respond to crisis. In the proposed model, humanitarian aid distribution centers (HADC), the number and location of them, the amount of relief goods stored in distribution centers, the amount of relief goods sent to the disaster zone, the number of injured people transferr...

History matching is used to constrain flow simulations and reduce uncertainty in forecasts. In this work, we revisited some fundamental engineering tools for predicting waterflooding behavior to better understand the flaws in our simulation and thus find some models which are more accurate with better matching. The Craig-Geffen-Morse (CGM) analytical method was used to predict recovery performa...

Seismic hazard assessment like many other issues in seismology is a complicated problem, which is due to a variety of parameters affecting the occurrence of an earthquake. Uncertainty, which is a result of vagueness and incompleteness of the data, should be considered in a rational way. Using fuzzy method makes it possible to allow for uncertainties to be considered. Fuzzy inference system,...

this paper presents a deterministic approach for performance assessment of different province’s road safety level at iran. a data envelopment analysis (dea) model considering undesirable input and output indices and a multivariate statistical method, principle component analysis (pca) are used in this paper, while previous studies do not use composite pca-dea method and undesirable input and ou...

Robust control design of vehicles addresses the effect of uncertainties on the vehicle’s performance. In present study, the robust optimal multi-objective controller design on a non-linear full vehicle dynamic model with 8-degrees of freedom having parameter with probabilistic uncertainty considering two simultaneous conflicting objective functions has been made to prevent the rollover. The obj...
