Recent advances in digital fabrication technologies have sparked a renewed interest in topology and biological form. The ability to design and prototype structural forms inspired by nature has challenged architects preconceived notions of space and form. With the assistance of parametric modeling and rapid prototyping we now not only have the ability to physically generate complex forms, but also the ability to create a seemingly infinite number of formal variations. As a result, this has caused architects to push toward new spatial concepts. Among these new spatial concepts are those that seek to create entire building systems out of a single material solution. Inspiration for such systems can be found by studying organic cellular structures. Unlike the component based design processes of most architects, in which multiple problems are solved through multiple material solutions, natural systems tend to create solutions that solve multiple problems through one material solution. This thesis is interested in answering the question, "Is it possible to create a building system (both structure and enclosure) out of a single adaptable building unit?" Furthermore, can the building unit also be capable of transforming from being either permeable to impermeable? If so, how might this challenge our existing notions of boundaries?

Texto completoSST turbulence model. For 3 different angles of attack cases, respectively, 4°
, 8°
and 12°
, several injection scenarios were defined. There are 3 steady injection cases for each angle of attack case namely, no injection case, uniform injection case, triangular waveform injection case where there is no injection at the leading edge tip whereas there is injection which is equal to the uniform injection velocity at the trailing edge tip. Moreover there are 5 additional scenarios for 8°
angle of attack case that are, sinusoidal waveform injection case which consists of a chordwise velocity distribution shape that is a quarter sinus wave where maximum injection velocity is the same as the uniform velocity, reverse triangular waveform injection case where injection velocities were reversed with respect to triangular waveform case, two cases consisting of angled injections having both +15°
and -15°
with respect to the flapping axis of the wing. The effect of tube walls on the jet injection was neglected for all cases, therefore for the last case, in order to simulate pipe flow, a case is provided with uniform injection velocity. In that way, regardless of the solution method, a parametric study was performed. Considering each case, non-dimensional 3-axis velocity components, turbulent kinetic energy, vorticity magnitude, pressure, lift and drag values were computed and having the exactly same cases as an experimental study for 8°
angle of attack, a comparison of aerodynamic data series was presented. As results, it&rsquo
s observed that, vortex core locations were shifted upwards and away from the tip region. Increasing the turbulence level of the tip flow by tip injection, inherently the pressure difference became larger, however as the vortices ascend, tip loss decreases. In that way, a significant increase in the lift was observed while drag values are slightly increased, as well.

A parametric investigation was conducted in order to characterize the mechanical response of two-dimensional composite scarf joints subjected to extensional loading, to determine the associated response sensitivities to joint parameters, and to establish the fundamental operative joint mechanics. The geometric parameters of equal scarf angles, adhesive thickness, and unequal scarf angles, and the laminate parameter of similar laminate configurations of both adherends of [+/-[theta]₂/0₂]S, [[theta]/0=0]₂S, and homogenized [[theta]₂/0₂]S (equivalently homogeneously orthotropic) were explored for values of [theta] of 45° and 15°. The ply regions of the laminates were modeled as transversely isotropic T700/2510 carbon/epoxy composite material, and the adhesive region as isotropic FM 300-2K polymer film adhesive. Linear elastic plane strain analyses were performed via finite element modeling. The results indicate that the overall mechanical response of two-dimensional composite scarf joints in the joint region is influenced by the global/macroscopic joint features of 'effective' through-thickness stiffness properties of the configuration in the joint region, and equilibrium considerations along the bondline, and by the local joint features manifested at the tips of the adherends at the ends of the joint region and through ply-by-ply level mismatch in stiffness properties within the adherend. The global peaks in the magnitudes of strains occur in the adhesive, and the distributions of strains in the adhesive essentially reflect the distributions of strains along the bondline in the adherend. The distributions of strains in the adherend along the bondline reflect the distribution of stiffness properties of the adherend through the thickness, and are governed by the local effects of mismatch in stiffness properties between the [theta] and 0° plies along with the lengthscale of the effective ply thickness. Sharp changes in the magnitudes of strains occur near the acute and obtuse tips of the adherend, and these are related to the overall length-scales of the configuration and show similar aspects to those occurring in laminated structures with ply drop-offs. The magnitudes of strains show the greatest sensitivity to variations in the scarf angle of the configuration, increasing with increasing values of scarf angle and associated changes in bondline length, but show little sensitivity to variations in the adhesive thickness of the configuration. For the asymmetric configurations of unequal scarf angles, the response characteristics exhibit combined effects of variations in scarf angles and adhesive thickness, and exhibit signicant asymmetry in the cross-sectional distribution of far-field longitudinal strain. Recommendations for further work are presented.

Texto completoFiber optic parametric amplifiers (FOPA) are promising for tomorrow's communication systems. In particular, fiber phase sensitive amplifiers offer attractive functionalities like low noise and high gain which makes it a potential candidate for applications in microwave photonic links. This thesis provides a theoretical investigation of such fiber phase sensitive amplifiers aimed towards applications.The first part of the thesis is dedicated towards development of an analytical model for propagation of seven CW waves through a FOPA. The system was solved exactly when nonlinear effects of the fiber are not strong. The developed model unravelled the important role of the higher order waves in determining the amplification performance of the FOPA. Strategies were formulated to enhance the amplification and the possibility of a phase sensitive frequency conversion with just two pump waves was also predicted.In the second part of this thesis, the possibility of introducing a fiber phase sensitive amplifier in a microwave photonic link for analog signal distribution was investigated. A numerical model was utilized to simulate how the RF nonlinearities in a microwave photonic link are amplified by the FOPA. The performance of the link when the FOPA attains a gain saturation was also studied. The study revealed the possibility of RF nonlinearity mitigation using the fiber nonlinearity. Implementation of such techniques could lead to realization of long-range and highly linear microwave photonic links for antenna remoting applications

Texto completoIndustry is permanently looking for minimizing production time and cost, simplifying their manufacturing process while maximizing the quality of their products. This is applied by the metal forming industry. In this context, an innovative forming process, the thixoforging, is developed, making it possible to manufacture complex parts with elevated mechanical properties. Moreover the thixoforging permit to minimize the number of phases of the manufacturing process. This process uses the semi-solid state properties of metal alloys, this state being obtained by partial fusion of the solid. For steel thixoforging, the difficulties related to the work temperature and the lack of knowledge of the mechanical and thermomechanical behavior of the material. These make the industrial process development difficult. This thesis contributes to improve comprehension of the steel behaviour during thixoforging. The objective is also to develop the exploitation of the original multi-scale model “micro-macro”, and its implementation in the 2D and 3D Forge2007®. Software. To achieve this goal, experimental testing with a specific and innovative device was carried out. The main thixoforging parameters were identified and studied. These parameters are the forming speed, the initial steel temperature and the initial tool temperature. For each test, the evolution of the forming load, the nature of the plastic flow and the quality of the thixoforged parts characterised by the macrographic and micrographic observations of their metallurgical structure and mechanical tests, were studied. Tests with instrumented tools also allowed a characterization of heat exchange between the tool and the part during forming. This big number of tests made it possible to describe the influence and to show the importance of the forming speed, the initial temperature of the steel and the initial temperature of the tool during thixoforging of a part. These tests were also used as a basis for calibration of the “micro-macro” model multi-scale and the heat exchange coefficients between the tool and the part. The tests and simulations were compared in order to determine and improve the predictive model capacity implemented in Forge2007® software
