X-ray diffraction from point-like imperfection
Displacement fields from point-like defects are investigated by x-ray diffraction. The atomic volume changes in the interstitial compounds using crystallographic information has been found to correlate with the size of filled octahedral sites. Systematic correlations enable estimates to be made of …

Imperfection-Aware Design of CNFET Digital VLSI Circuits
… CNTs are the dominant type of CNT variations/imperfections that cause performance variation, large static power consumption, and yield degradation. We present an imperfection-aware design technique for CNFET digital VLSI circuits by: 1) Analytical models that are developed to analyze and …

Towards a Cinema of Imperfection: Participatory Film as Research
… of the emancipatory potential of the idea of imperfection. It is framed around the key leading question: ‘How can the generation of imperfect praxis – cultural production in and through social dialogues challenging notions of technical expertise – affirm emancipatory value in a film practice? …

We Were Such a Happy Family: Lessons in Imperfection
… 100-word stories, and poetry examines themes of imperfection, love, and loss—and what it means to be a family—against the backdrop of the COVID-19 pandemic.</p>

Analysis and Compensation of Imperfection Effects in Piezoelectric Vibratory Gyroscopes
… The performance of these sensors is limited by imperfections that occur during manufacture of the resonators. The effects of resonator imperfections, in piezoelectric vibratory gyroscopes, were studied. Hamilton's principle and the Rayleigh-Ritz method provided an effective approach for modeling …

COMPULSORY ABLEISM IN THE RHETORICAL SITUATION: THE IMPERFECTION OF EXIGENCY IN THE CASE AGAINST PERFECTION
In many contexts I think of myself as able-bodied. But, disability is best determined relationally in particular contexts, and in certain instances my body does not fit the compulsory conditions of universal able-bodiedness. Disability and able-bodiedness change in given circumstances and across …

Chaucerian imperfections: The other and the turbulant self
This thesis is interested in forms of “imperfection” in Geoffrey Chaucer’s Canterbury Tales. I define “imperfection” as an authorial gesture performed to narrate an idealized virwhile depriving it from its idealism. The imperfection of a virtue, however, does not happen absolutely. It is the …

Determination of Mueller matrix elements in the presence of imperfections in optical components
… matrix in the ideal case, azimuthal offsets and imperfection parameters are introduced in the straight-through configuration and the imperfection parameters are determined from the Fourier coefficients. Finally, the sample is reintroduced and the full Mueller matrix elements are calculated to …

Stochastic Methods for Robust Design of Launch Vehicle Structures
The important role of initial imperfections on decreasing the buckling load of imperfection sensitive thin-shelled structures, commonly used on launch vehicles such as the Ariane family, has been widely studied since the 1930s. Research in this area has resulted in a variety of analytical and …

Instabilidade e sensibilidade de cascas cilíndricas circunferencialmente enrijecidas
An analysis of the buckling load and the imperfection-sensitivity of ring stiffened cylinders under external pressure is presented. Koiter's general post-buckling theory provides the basis to estimate the imperfection-sensitivity by relating it to the initial post-buckling behavior of the perfect …

The effect of weld-induced imperfections on the buckling behaviour of spherical and conical shells
The early research was on general imperfections most commonly in the form of the lowest buckling modes. The use of steel pates to fabricate silos in a regular pattern led to the civil engineering interest in the weld-induced imperfection. This imperfection was found to be in the circumferential …

Thermal Bending, Buckling and Post-Buckling Analysis of Unsymmetrically Laminated Composite Beams with the Effects of Moisture and Geometric Imperfections
… unsymmetrically laminated composite beams with imperfection under hygrothermal effects. Three different boundary conditions will be considered on this study. The non-linear governing partial differential equations are derived by taking into account the von-Karman geometrical nonlinearity for an …

Essays in financial economics
… the relation between liquidity and market imperfections from two dimensions: 1) Across liquidity measures, we compare the influence of imperfections on two commonly used measures, Kyle's lambda and price reversal; 2) Across imperfections, we study the interaction between two sources of …

Minimum-weight design of compressively loaded stiffened panels for postbuckling response
… response. Comparisons of panel weight and imperfection sensitivity between the NLPANOPT designs and PASCO designs are presented. In general, the designs obtained with NLPANOPT are lighter and less imperfection sensitive than the designs obtained with PASCO. The nonlinear analysis allows for …

A method for the geometrically nonlinear analysis of compressively loaded prismatic composite structures
… to be simply supported, and geometric shape imperfections can be modelled. The method can predict the nonlinear phenomena of postbuckling strength and imperfection sensitivity which are exhibited by some buckling-dominated structures. The method is computer-based and is semi-analytic in …
