An approach to map soil texture class on the Iowan Erosion Surface
… was to compare approaches of new and legacy dataset combination to produce surface soil texture class maps on the Iowan Erosion Surface physiographic region (MLRA 104) using standard and novel predictor variables (covariates) for modeling. Hand-textured and laboratory-analyzed legacy particle …

Pieces of a Puzzle: Fitting Electromagnetic Induction into Geophysical Strategies to Produce Enhanced Archaeological Characterisation
… improving the quality and accuracy of collected data. The link between instrument measurements and buried archaeology was further developed through a structured analysis of the EM datasets with complementary earth resistance and magnetic results. The integration of the EM, earth resistance and …

Estratégias de inversão de multiparâmetros utilizando a equação completa da elastodinâmica
… by using acoustic or elastic synthetic data. The results shows that the acoustic inversion is not sufficiently accurate to adjust the amplitudes of elastically generated data. Finally, it is explored the use of 3C/2D multicomponent (hydrophone and vertical and horizontal components of …

Mapping vegetation with remote sensing and GIS data using object-based analysis and machine learning algorithms
… include the diverse range of high quality data sources and image analysis techniques. Object-based image analysis (OBIA) and machine learning algorithms are recent advances, which this thesis evaluates. OBIA and machine learning algorithms are first tested using a combination of multiple …

Three Essays in Applied Microeconometrics
… Levell, proposes a novel estimator useful for data combination. Researchers are often interested in the relationship between two variables, with no available data set containing both. For example, surveys on income and wealth are often missing consumption data. A common strategy is to use …

Adversary analysis of cockroach network under Rayleigh fading channel: Probability of error and adversary detection
… into two directions: probability of error for data transmission and probability of detection for adversary node. A lookup table is proposed in order to speed up the process of data decoding and also to identify the node that has the highest probability of behaving as an adversary. This table is …

A molecular phylogeny of the subfamily Arundinoideae (Poaceae)
… or unknown. Because morphological and anatomical data have, to date, been unable to elucidate relationships among these genera, sequence data from two chloroplast genes are used to elucidate relationships among 33 arundinoid genera. Sequence data from the variable, grass-specific insert in the …
