This item is printed on demand - it takes 3-4 days longer - Neuware -Two new developed multinomial logistic regression approach is proposed by incorporating the concepts of fuzzy sets. The first is formulated using a goal programming approach, while the second is formulated as a multi objective progr…amming model. These two models are based on the assumption that the parameters are fuzzy. A simulation study is used to evaluate the suggested models comparing to the classical approach. Data are generated from different multinomial logistic models The design of the simulation study considers 40 different combinations of three factors. For each combination, a comparison between the performance of the proposed approach and ML approach is presented. 124 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Parameter estimation for logistic regression is usually based on maximizing the likelihood function. For large well-balanced datasets ML estimation is a satisfactory approach. Unfortunately, ML may fail completely or at least produc…e poor results in terms of estimated probabilities and confidence intervals of parameters, specially for small datasets. This study extends logistic regression model to fuzzy logistic regression model by suggesting a new approach based on fuzzy concepts to estimate the model parameters. This study produces three proposed mathematical models with different objective functions. The first is formulated as a bi-objective programming model. The second is formulated using a goal programming approach, while the third is a mathematical programming model which minimizes the total spread of the estimated probabilities of the logistic model. The proposed models are evaluated and their results are compared to ML results through a Monte Carlo simulation study. The results are analyzed and summarized to conclude the following: The proposed models outperform ML approach for small size data sets with respect to the similarity measure as goodness of fit index 124 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Photocatalysis plays an important role in dealing with today's challenges demand for drinking water and waste water treatment technology. This work involves two directions to improve photocatalytic efficiency with economical benefit…s by different modification methods. One is the preparation of nanosphere and mesoporous titania nanoparticles. The other, a magnetic photocatalyst was prepared by coating of spinel cobalt ferrite as magnetic core with an insulating silica layer and photocatalytic properties of the outer titanium dioxide shell. Utilization of solar energy for the environmental cleanup becomes the future goal of the scientists. New visible light magnetic - titania photocatalysts that contain a small band gap semiconductor coupling open up new possibilities for the development of solar-induced, separation and recyclability photocatalytic materials. 332 pp. Englisch.
