A history of the present : recognizing the complex and shifting nature of racism and resistance in the life narratives of the Khayelitsha Internal Forces
… with five former-members of the Khayelitsha Internal Forces. The Internal Forces represent a group of ex-combatants who were operating in the Western Cape as a para-military Self Defense Unit (SOU) during the 1986-1994 period of popular township revolt. The first stage of analysis consists of …

Seismic behaviour of anchored steel sheet pile walls in sand
… the main parameters affecting their maximum internal forces and displacements. In this research project, the seismic behaviour of ASSP walls in dry and saturated sand was investigated. A series of dynamic centrifuge tests showed that, in dry conditions, the maximum internal forces were driven …

Contribuição ao projeto de fundações em radier
… is to establish criteria for the computation of internal forces in mat foundations, following a comparative study of the various models and methods proposed in the technical literature and Codes of Practice.

The analysis of symmetric structures using group representation theory.
… the loads applied to a structure, and the internal vector space wh",t-k is-suitable for representing the internal forces. Using these symmetry-adapted coordinate systems the equilibrium matrix is block-diagonalised into a number of independent submatrix blocks, thus decomposing the analysis …

A chronicle of dependence : Cuba from the rise of sugar until the failure of the ten million ton Zafra of 1970
… of how the interrelation of external and internal forces in pre-revolutionary Cuba resulted in a classic form of dependency, followed by revolutionary victory, and eventually socialism. Finally, the study offers four observations based on socialist Cuba's development effort of the 1960s …

Análise linear de estruturas planas com elementos de paredes delgadas
… other two examples - grid and plane frame - the internal forces and the stresses were compared with results obtained with a method of analysis that considers members with plane behaviour of cross section.

A computational bow-spring model
… force) is difficult to model, because internal forces and moments and the geometry are both unknown. The only closed-form solutions to such systems are relatively useless to a mechanical engineer. This work comprises an iterative model developed in MATLAB that computes the mechanical …

Dynamic Analysis Of Turbine-generator-foundation Systems
… strongly influences the displacements and internal forces of the system under rotor unbalance excitation. Under seismic excitation, however, although the presence of casing and soil anisotropy does affect the displacements of the system, their effect on the internal forces of the system is …

The Post-apartheid South African Economy in the global economic system, 1994-2004
… in the country's interest. International and internal forces had to be balanced for the sake of a new developing economy. South Africa had to align its economic development along better development initiatives elsewhere. Balancing political and economic options was not an easy task as shown by …

Análise tridimensional de estruturas de edifício
… allowing computations of displacements and internal forces for buildings up to 50 stores with up to 25 joints for each floor. The prograrn was designed for a IBM 360/40 computer. This prograrn takes advantage of the properties of the band matrix that caracterizes the stiffness matrix. The …

Micromachined Sensors and Their Applications in the Study of Mechanical Response of Single Living Cells
… play a dominant role in taking the cellular internal forces; Mechanical indentation/compression may induce actin agglomeration inside the cell, which supplies a perfect example of cellular mechanotransduction; The in vivo stretch force response of Drosophila axons is linear, and there is a …

Numerical Analysis of a Generalized Plane Plastica
… is developed for finding the displacements, internal forces, and reaction forces on any planar, continuous, and flexible structural member such as a beam, column, ring, or simply-connected frame. Euler-Bernoulli theory, in which plane sections remain plane and strains are small, is assumed. …

Lifting Analysis of Precast Prestressed Concrete Beams
… for calculating the roll angle of the beam, the internal forces and moments, the weak-axis and strong-axis deflections, and the cross-sectional angle of twist. Finite element simulations are performed to investigate the behavior of concrete beams during lifting and to validate the proposed …

Dimensionamento plástico de edifícios de andares múltiplos, em aço
… steel property, and the redistribution of internal forces in statically indeterminate structures that takes place when plastic hinges develop at regions of a high bending moment. In multistory frames, additional moments caused by the P-∆ effect must also be taken into account. The …

Análise de edifícios pelo método das estruturas equivalentes
… A computer program is presented to compute the internal forces in slabs, beams and columns of building and the displacements in each nodal point. This program uses the properties of the banded stiffness matrix. The technique used to assemble and store the stiffness matrix is a modified version …

Equilibrium analysis of masonry domes
… for the ability of domes to achieve a range of internal forces, gaining potentially an infinite number of equilibrium solutions that could not be derived otherwise. This method can also analyze non-conventional axisymmetrical dome geometries that are difficult or impossible to analyze with …

An investigation of an existing aluminum lattice dome under snow loads
… to four times the member stiffness. The internal forces in the pinned-end and framed-end models were compared to the specifications by the Aluminum Association. The pinned-end model under the unbalanced snow load were found to exceed the allowable. The maximum deflection occurred when the …
