Fundamental Study Of Nonlinear Electrophoresis, Joseph Armakan Bentor

All Dissertations

Classical electrophoretic theory describes the linear response of particles suspended in Newtonian fluids under weak electric fields. When the electric field exceeds this weak limit, a nonlinear response arises due to non-uniform surface conduction over the curved particles. This nonlinear behavior introduces dependencies on fluid and particle properties not considered in the classical theory, offering potential advantages for microfluidic particle manipulation. While this phenomenon has been extensively studied theoretically and numerically in Newtonian fluids, experimental investigations have been relatively limited.

Fluid rheology can significantly alter particle dynamics under applied electric fields. Rheological properties like shear-thinning and elasticity which are not …

Everyday Ingroup Colourism And Racial Esteem: Investigating The Moderating Role Of Assimilation To A Nationalistic Identity Among Afro And Indo Trinidadians, Jenneil Charles

All Dissertations

Colourism is a form of prejudice based on skin tone that occurs intraracially among communities of colour. Whereas light-skin tones are highly favoured, dark-skin tones are privileged in terms of perceived ethnic authenticity and legitimacy, thus, leading to assumptions about greater group level support and resources for dark-skinned persons. This study challenges these assumptions on the premise of ingroup colourism jeopardizing the relationship between Afro and Indo Trinidadians, and their racial-ethnic groups based on the tenets of Social Identity Theory and Social Identity Threat Theory. Social Identity Threat Theory proposes that the response to rejection from one’s ingroup depends on …

Linear And Nonlinear Topology Optimization With Morphing Beam Networks, Andrew S. Montalbano

All Dissertations

Topology optimization (TO) is an engineering design discipline dedicated to optimizing material distribution within a given domain. In traditional gradient-based topology optimization, the solid domain is discretized into small volumetric elements. Using finite element analysis (FEA) of the structure, the gradient of the objective function with respect to the design variables (the pseudo densities) is computed, and these design variables are updated iteratively until convergence is achieved. Although gradient-based TO methods are well-established, sensitivity analyses of objective functions and constraints can be both mathematically complex and computationally intensive. The nonconvex nature of most TO problems often complicates efficient convergence. Furthermore, …
