Non-linear analysis of infilled frames.
This thesis is concerned with the analysis of building frames acting compositely with infilling wall panels. The significance of the composite action is emphasized and previous work on infilled frames is reviewed. The existing methods of analysis are categorized and their analytical assumptions are …

Linear analysis and optimization of stream programs
… a set of aggressive optimizations that target linear sections of a stream program. Our input language is StreamIt, which represents programs as a hierarchical graph of autonomous filters. A filter is linear if each of its outputs can be represented as an affine combination of its inputs. …

Role of the Curved Parametric Element in Linear Analysis of Thin Rotational Shells.
… previous research had been in developing a linear and a curved parametric element applied to axisymmetric oscillations of thin shells of revolution.<br/><br/>The current scheme was confined to applying the above curved parametric element to the axisymmetric static case and was then developed …

Variation Simulation of Fixtured Assembly Processes for Compliant Structures Using Piecewise-Linear Analysis
While variation analysis methods for compliant assemblies are not new, little has been done to include the effects of multi-step, fixtured assembly processes. This thesis introduces a new method to statistically analyze compliant part assembly processes using fixtures. This method, consistent with …

Linear analysis of laminated composite plates using a higher-order shear deformation theory
A higher-order shear deformation theory is used to analyze laminated anisotropic composite plates for deflections, stresses, natural frequencies, and buckling loads. The theory accounts for parabolic distribution of the transverse shear stresses, satisfies the stress-free boundary conditions on the …

Beethoven Sonata for Piano and Cello, Op. 69 in a Major: A Linear Analysis
… its formal architecture and more to do with the linear progression and development of themes. Composers in this style did not approach the form in terms of the three sections it contains, though they did maintain these groups. There first needed to be an exposition where two contrasting themes, …

Análise não-linear física de vigas contínuas em concreto armado e protendido
A non-linear analysis is developed for a prestressed concrete continuous beam, based on the theory of the finite-element method. As a consequence of the theoretical study, a computer program in FORTRAN is developed. This program performs a physical non - linear analysis of a prestressed continuous …
