Debris disks are optically thin circumstellar disks around mainsequence stars, comprised of micron-sized grains. The dust is generated from destructive collisions of planetesimals, induced from gravitational perturbations by large planets. Debris disks can as signposts for planetary systems, through which, a universal ...

This thesis focuses on the development of an artificial intelligence system for a heterogeneous ensemble of mobile robots. Many robots in the ensemble may have limited processing, communication, sensing, and/or actuation capabilities. This means that each robot may not be able to execute all tasks that are input to ...

Hermeneutic-phenomenological interviews were conducted to explore community-based extension workersÍ (CBEWsÍ) previous work and training experiences and how such experiences contributed to their present working relationships as partners in community development. CBEWsÍ responses foreshadowed challenges and ...

The theory of the commodity is used by critical theorists to explain the general organization and development of capitalist society. It was originally proposed by Marx, and subsequently developed by Lukacs and later Adorno and the Frankfurt School. Media scholars such as Dallas Smythe, Judith Williamson, Robert ...

As late as 1995, the anticipated widespread population of primeval galaxies remained at large, lurking undetected at unknown redshifts, with undiscovered properties. We present results from our efforts to detect and characterize primeval galaxies by their signature high-redshift Lyman-alpha emission lines utilizing ...

Using a quantitative causal-comparative approach, the researcher conducted a relational study that compared injured and rehabilitated soldiers with no religious foundation to similar soldiers possessing religious preferences and spirituality. The two primary research questions were (a) Does religious preference and ...

Upper body power (UBP) is one of the most important factors affecting the performance of cross-country skiers during races. Although some initial studies have already attempted to predict UBP, until now, no study has attempted to apply machine learning methods combined with various feature selection algorithms to ...

The study examined the effects of rural and urban orientations on pupils’ performance on WISC-R (a standardised intelligence test). The study made use of an experimental method. The data were collected on a sample of 100 primary school pupils (50 rural and 50 urban). The participants were from grade 5 and had an ...

This study analyzes experimental data generated by human subjects using the Perspecta 3D Volumetric Display and a 2D flat screen liquid crystal display (LCD). The analysis reveals differences in how experiment participants used the display technologies.

The purpose of this thesis is to develop new hybrid admission decision prediction models by using different machine learning methods including Support Vector Machines (SVM), Multilayer Perceptron (MLP), Radial Basis Function (RBF) Network, TreeBoost (TB) and K-Means Clustering (KMC) combined with feature selection ...
