▼ Although multiplicative structures can be modeled by additive structures, they have their own characteristics inherent in their nature, which cannot be explained solely by referring to additive aspects. Thus, this study is about preservice teachers’ understanding and sense making of representational quantities generated by magnetic color cubes and algebra tiles, the quantitative units (linear vs. areal) inherent in the nature of these quantities, and the quantitative addition and multiplication operations - referent preserving vs. referent transforming compositions (Schwartz, 1988) - acting on these quantities. I devised a set of tasks focusing on identities of the form “Sum = Product,” which can also be thought of as summation formulas. Data came from videotaped individual interviews during which I asked five (2 middle school and 3 high school mathematics) preservice teachers problems related to six main mathematical ideas: modeling prime and composite numbers; summation of counting numbers, odd numbers, even numbers; and multiplication and factorization of polynomial expressions in x and y. I base my analysis within a framework of unit-coordination with different levels of units (Steffe, 1988, 1994) supported by a theory of quantitative reasoning (Schwartz, 1988; Thompson, 1988, 1993, 1994, 1995). I used a simplified version of Behr, Harel, Post, & Lesh’s (1994) generalized notation for mathematics of a quantity and Vergnaud’s (1983, 1988, 1994) theorems and concepts in action formalisms, which helped me describe the preservice teachers’ understanding of linear and areal quantities and their units, and the quantitative operations taking place; and translate students’ mathematical performance into a series of terminology based on a simple notation: Relational notation and mapping structures duo (Caglayan, 2007b). There was a pattern, which showed itself in all my findings. Two students constantly relied on an additive interpretation of the context whereas three others were able to distinguish between and when to rely on an additive or a multiplicative interpretation of the context. My results indicate that the identification and coordination of the representational quantities and their units at different categories (multiplicative, additive, pseudo-multiplicative) are critical aspects of quantitative reasoning and need to be emphasized in the teaching-learning process.

This thesis studies three problems in linear algebraic and additive combinatorics. Our first result gives new upper bounds for the determinant of an nimes n zero-one matrix containing kn ones. Our results improve upon a result of Ryser for k=o(n^1/3). For fixed kge 3 it was an open question~cite{bruhn} whether Hadamard's inequality could be exponentially improved. We answer this in the affirmative. Our approach revolves around studying mimes n matrices whose rows sum to k and bounding their Gram determinants. For the class of nimes n matrices whose rows sum to k we show that Ryser's result can be improved for kle sqrt{n/10}. Our technique also allows us to give upper bounds when these matrices are perturbed. Our second result concerns a question in additive combinatorics. For a prime p>2, we say a nonempty set Asubseteq F_p is emph{unique sum free} (USF) if every element of the sumset A+A can be written as a sum of two elements from A in at least two different ways. That is for any s in A+A there exist a,b,c,d with {a,b}e{c,d} such that s=a+b=c+d. If μ(p) is the size of the smallest USF set in F_p it is straightforward to show that μ(p) = O(sqrt{p}). Kopparty~cite{koppartyconference} conjectured that μ(p)=Theta(sqrt{p}). However, we show constructively that μ(p)=O(log² p). Our third result concerns a graph theoretic problem on the Hamming cube, Q_n. For a graph, G, we say a proper k-coloring of G is a fall k-coloring if each vertex is adjacent to a vertex in each of the k-1 other color classes. A result of Laskar and Lyle~cite{laskar} shows that for ke 3 and n sufficiently large Q_n has a fall k-coloring. It is natural to identify the Hamming cube, Q_n, with the vector space F₂ⁿ. In this context we may seek fall k-colorings of F₂ⁿ in which each color class is an affine subspace. Our main result is that for even k and n sufficiently large there exist affine fall k-colorings of F₂ⁿ. In particular, we show these exist for the same range of values of n as in the construction of Laskar and Lyle.

▼ Monotone additive models are useful in estimating productivity curves or analyzing disease risk where the predictors are known to have monotonic effects on the response. Existing literature mainly focuses on univariate monotone smoothing. Available methods for the estimation of monotone additive models are either difficult to interpret or have no asymptotic guarantees. In the first part of this dissertation, we propose a one-step backfitted constrained polynomial spline method for the estimation of monotone additive models. In our proposed method, we obtain monotone estimators by imposing a set of linear constraints on the spline coefficients for each additive component. In the second part of the dissertation, we extend the constrained polynomial spline method to estimate the production frontier that is used to quantify the maximum production output in econometrics. The estimation of frontier functions is more challenging since it is the boundary of the support rather than the mean output function to be estimated. Here, we develop a two-step shape constrained polynomial spline method for the frontier estimation. The first step is to capture the shape of frontier while the second step is to estimate the location of frontier. Both proposed methods in this dissertation give smooth estimators with the desired shape constraints (monotonicity or/and concavity). They are easily implementable and computationally efficient by taking advantage of linear programming. Most importantly, our methods are applicable for multi-dimensions where some existing methods fail to work. For the assessment of properties of the proposed estimators, asymptotic theory is also developed. In addition, the simulation studies and application of our methods to analyze Norwegian Farm data in both parts suggest that our proposed methods have better numerical performance than the existing methods, especially when the data has outliers.

La Fabrication Additive (FA) vient aujourd’hui bouleverser des habitudes de conception bien ancrées, et suscite dans le même temps un intérêt grandissant pour les perspectives qu’elle offre pour l’innovation produit. Pourtant, alors que les enjeux liés à l’innovation sont prépondérants en conception amont, peu de concepteurs connaissent et utilisent le potentiel des connaissances FA pour développer puis sélectionner des solutions créatives. Dans ce contexte, notre recherche a pour objectif d’augmenter la capacité d’innovation des concepteurs en intégrant des connaissances FA lors de la conception amont. Pour cela nous proposons d’intégrer des connaissances FA explicites dites « au juste besoin », c’est-à-dire dont le contenu, l'instanciation et le support sont adaptés aux besoins des équipes de conception. De plus, nous proposons que cette intégration s’effectue dans un modèle de conception permettant l’approche Design With Additive Manufacturing (DWAM). Nos apports sont la proposition : d’une démarche, basée sur le Knowledge Management, permettant de repérer, capitaliser puis valoriser les connaissances FA au juste besoin ; mais également d’un modèle de conception amont en 3 étapes dans lequel les connaissances FA utiles à l’approche DWAM sont spécifiées. Enfin, ce modèle enrichi est valorisé dans un outil numérique support afin de faciliter le travail collaboratif et concourant.

The onset of Additive Manufacturing (AM) upsets design practices and is receiving attention because its potential is promising for product innovation. However, while innovation issues are paramount during early design stages, few designers have sufficient knowledge about AM and use it poorly to develop creative solutions. Thus, our research objective is the increase of the innovation capacity of the design team through the integration of AM knowledge into early design. To do this, we propose to use “just needed” AM knowledge, i.e., AM knowledge whose contents, supports and instancing are tailored to the design team needs. Moreover, we propose that this integration takes place in a design model that allows the Design With Additive Manufacturing (DWAM) approach. Our contributions are both the proposal of a methodology based on Knowledge Management dedicated to the identification, the capitalization and the valorization of the “just needed” AM knowledge; and of a design model in 3 stages, in which the useful for DWAM approach AM knowledge is specified. Finally, this enriched model is valued in a digital tool in order to improve collaborative and concurrent design.

▼ Additive Manufacturing (AM) is the name given to a series of processes used to create solids, layer upon layer, from 3 Dimensional (3D) models. As AM experiences rapid growth there exists an opportunity for Selective Laser Sintering (SLS) to expand into markets it has not previously accommodated. One of the ways SLS can accomplish this is by expanding the range of materials that can be processed into useful products, as currently only a small number of materials are available when compared to other AM technologies. One of the biggest barriers to the adoption of materials is the danger inherent to high-energy processes such as SLS. The aim of this research was to identify opportunities to improve current methods for modelling the relationship between material specifications, and printing parameters. This was achieved by identifying existing models used to determine printing parameters for a new material, identifying weaknesses in current modelling processes, conducting experimentation to explore the validity of these weaknesses, and exploring opportunities to improve the model to address these weaknesses. The current models to determine printer parameters to achieve successful sintering include both the Sintering Window (SW) and the Energy Melt Ratio (EMR). These two models are complementary, and both are required to establish all common print parameters. They include both thermal and physical powder properties, but do not include any optical properties. This is significant because the nature of the SLS printing process relies on concentrated delivery of laser energy to achieve successful sintering. Analysis of two similar polyamide powders, one black and one white, identified that the two powders were similar thermally and physically, which meant the models predicted that they should both sinter successfully utilizing the same set of print parameters. Results of the experimental trials showed that no trials involving the white powder sintered successfully, and trials involving the black powder suffered from issues with either insufficient energy to successfully remove parts without damage, or excessive energy causing excess powder to bond to the part. Further experimentation was carried out to investigate the differences in optical properties using Fourier Transform Infrared Spectroscopy (FTIR) and Spectrofluorophotometry. FTIR revealed that there was a difference in absorption as a material property, indicating that differences in laser energy absorption could explain the results seen in the trials. Spectrofluorophotometry revealed minimal differences in fluorescence of the powders, suggesting it an unlikely source of energy loss. Future work is recommended to research a standardised form of testing setup that can be used to categorize the reflectance of a material, as current work relies on proprietary experimental setups. Finding methods of classifying the laser absorption that is easily available to operators would enable refinement of the EMR equation to reflect the energy losses…

▼ This study investigates the combined effect of three Additive Manufacturing (AM) build orientations (0° , 45° , and 90° ) and an extensive array of heat-treatment plans on the plastic anisotropy of EOS maraging steel 300 (coded by EOS as ’MS1’) fabricated on the EOSINT M280 Direct Metal Laser Sintering (DMLS) system. A comparison between the material microstructural characteristics, mechanical performance, plastic strain behaviour and anisotropy levels of identical parts fabricated on two of these independently operated DMLS systems was also conducted. Considerable plastic anisotropy has been confirmed in the as-built condition, which can be reduced by aging heat-treatment, as verified in this study. However, it has identified that a degree of transverse strain anisotropy is likely to remain due to the AM alloy’s fabrication history, a finding that has not been previously reported in the literature. Significant microstructural discrepancies, affecting mechanical performance, plasticity and anisotropy levels, have also been observed in the as-built samples obtained from the two DMLS systems. A difference in the angle of the laser scan strategy, in conjunction with unfavourable powder feedstock characteristics, are understood to have had a profound influence on the plasticity and anisotropy divergences observed. A comprehensive visual representation of the material’s overall mechanical properties against the various heat-treatment plans is offered through time-temperature contour maps. Moreover, the heat-treatment plan (6h at 490° C) recommended by the DMLS system manufacturer has been found not to be the optimal in terms of achieving high strength, hardness, ductility and low anisotropy for the MS1 material. With the use of the comprehensive experimental data collected and analysed in this study, and presented in the constructed contour maps, the alloy’s heat-treatment parameters (time, temperature) can be tailored to meet the desired strength/ductility/anisotropy design requirements, either for research or part production purposes.

▼ Additive Manufacturing (AM) is a method of producing three-dimensional objects using additive processes. It allows great flexibility in the processes and reduces the design-to-production time. Laser Metal Deposition (LMD) is one of AM methods under development and is based on the deposition technology. LMD has advantages in grain growth control, material functional grading, lower material storage requirement and more spatial freedom. Considering the outstanding features, it is important to study the characteristics of LMD products, which in this study is Alloy 718 for aerospace applications. Single-wall Laser LMD samples are built with varied process parameters using gas-atomized Alloy 718 powders. Two experiments were carried out with focuses on 1) evaluations and comparisons of the microstructural characteristics, porosity and hardness of the samples are performed; 2) The effect of heat treatments including solution treatment and aging on the microstructure as well as the hardness. The results of the experiments revealed directional solidification features and typical phases such as γ matrix, Laves phase and carbide. 0.06% average porosity and a majority of < 20 µm size are measured from the LMD samples. Only spherical gaseous pores are found while no lack-of-fusion pore is found. A hardness Vickers of 246 in average hardness is measured from the LMD samples. In the heat treated samples, δ phases were found; By direct-aging at 750 ℃ for 10 to 15 hours, the samples reach a maximum hardness of around 382 HV. The same hardness was reached by 1 hour of solution treatment at 950 ℃ followed by 5 hours aging at 750 ℃. The effects of processing parameters on the characteristics of LMD processed Alloy 718 are compared and discussed. A 2-dimentional map of porosity distribution along the length of the sample is made and the patterns are investigated along both the length and the height of the sample. It is found in the sample that the starting part of the deposit is higher in number of pores while the finishing part is larger in pore size. It is also found that the top layer of the deposit has the highest porosity level, pore number and pore size. Moreover, the hardness gradient along the build-up direction is evaluated and discussed. No significant hardness gradient was found. The precipitation hardening effect of LMD process and possible improvements are also discussed.

▼ Electron Beam Freeform Fabrication (EBF3) is a technique, developed at NASA Langley Research Center (NASA-LaRC), which uses a computerized numerical controlled electron beam welder and a wire feed system to fabricate large scale aerospace parts. Advantages of using EBF3 as opposed to conventional manufacturing methods include decreased deign-to-product time, decreased wasted material, and the ability to adapt controls to produce geometrically complex parts. The EBF3 process is compatible with a range of aerospace alloys and material properties of parts produced by this process have been shown to be comparable to wrought products. However, to fully exploit the potential of the EBF3 process, development of materials tailored for the process is required. This research used alloy theory, as well as powder cored tubular wire technology, to develop aluminum based metal matrix composite feedstock for the EBF3 system. Five iterations of powder cored tubular wire were made using silicon carbide particulates with different surface conditions. Uncoated particles, as well as particles with high and low amounts of copper and nickel coatings, were incorporated into the powder core. Single and multiple layer deposits were made using each wire. Beam conditions were varied for each wire to determine the optimal combination of feedstock material and electron beam parameters required to create a uniformly distributed metal matrix composite deposit using EBF3. Completely uniform dispersion of the reinforcement particles was not achieved in the matrix, however, it was determined that nickel additions enhanced particle dispersion as well as mitigated solidification cracking and secondary carbide formation. It was also determined that using a lower energy beam also promotes dispersion and mitigates secondary carbide formation. Computational models were created to predict phase transformations and particle dispersion in the matrix for various conditions. The thermodynamic and fluid dynamic models were able to describe trends observed through characterization of EBF3 depositions. Results collected from characterization of the deposits as well as trends observed in the models can be used to plan future iterations of powder cored tubular wire feedstock, as well as deposition parameters, to create homogeneous metal matrix composite structures by Electron Beam Freeform Fabrication.

▼ The impact of radiation-induced effects on the properties of alloys fabricated using additive manufacturing (AM) was evaluated through the implementation of ion beam irradiation testing followed by electron backscatter diffraction (EBSD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), nanoindentation, scanning probe microscopy (SPM), and transmission electron microscopy (TEM). Inconel 600 (I600) and 316L stainless steel (316L) rods were fabricated by Quad City Manufacturing Laboratory in collaboration with Lockheed Martin for this study. The rods were produced in three distinct orientations (vertical, horizontal, and 45°) using laser additive manufacturing (LAM). Conventionally manufactured I600 and 316L rods were purchased from Metal Samples, Inc. to enable comparative studies. The I600 and 316L LAM specimens were heat treated to 900 °C and 650 °C in argon with no cold working, respectively. Similarly, the conventionally manufactured I600 and 316L control specimens were cold rolled and annealed at 980 °C and 1040 °C in argon with no cold working, respectively. XRD of unirradiated specimens showed differences in peak ratios between build orientations, indicating anisotropic grain structures for samples fabricated by LAM. All LAM rods contained significantly fewer coincidence site lattice (CSL) boundaries and more residual strain compared to the controls before and after irradiation, regardless of build direction, as determined by EBSD. Material performance parameters such as resistance to radiation-enhanced embrittlement, corrosion, creep, intergranular stress corrosion cracking, and hydrogen-induced cracking were inferred from CSL theory, which suggests that all LAM rods are more susceptible to grain boundary-related failure mechanisms than their conventionally manufactured counterparts. All alloys built by LAM are strongly textured with parallel to the build direction before and after irradiation. Directionally dependent Taylor Factor distributions suggest that resistance to slip depends on build direction where, from highest to lowest resistance: horizontal > 45° > vertical. All I600 samples experienced radiation-induced segregation which, according to SEM/EDS and SPM studies, resulted in the formation of chromium carbide precipitates on to the irradiated surfaces. Strong anisotropic mechanical behavior was observed in the LAM rods, as measured by nanoindentation and bulk tensile testing. The hardness of the unirradiated as-annealed specimens, from greatest to least, is: horizontal > 45° > vertical. The radiation-induced hardening of LAM specimens, from greatest to least, is: horizontal > 45° > vertical. The orientation dependence of radiation-induced segregation and hardening mechanisms is discussed. The ultimate outcome of this work is a first-of-a-kind high-dose radiation damage study of alloys fabricated by LAM, revealing that the radiation-induced changes in material properties for these alloys is dependent upon build orientation.

▼ Degradable implants for bone fixation have been of significant interest since the last decade. Among different materials, magnesium appears as a promising candidate due to its unique combination of properties. Magnesium is very well tolerated by the body and has a natural tendency for degradation. In addition, its low elastic modulus helps to reduce stress-shielding effect during bone healing. Mg- Ca alloys are particularly of interest for the additional processing and property benefits that Ca addition provides. The potential use of these alloys necessitates multi-faceted studies so that microstructures with an optimal compromise between mechanical properties and degradability kinetics are achieved. This work focuses on Mg-2wt.%Ca alloy and aims to provide a path for future optimization of the alloy for implant applications. In this work a new bulk/surface processing approach is proposed: i.e. tailoring the bulk microstructure by thermomechanical treatments and surface functionalization by additive manufacturing. Hot rolling, extrusion and equal channel angular pressing (ECAP) have been used for bulk processing. The characterization results show that while different microstructural features (dislocations, twins, grain size) can account for the improvement in the mechanical strength, the improvement in the corrosion resistance appears as primarily affected by grain size and second phase microstructure. It is found that the severe plastic deformation induced by the ECAP process produces the finest grain structure and second phase particle distribution. This influence results from the dispersion of the second phase Mg2Ca and possibly a more stable oxide layer. The ECAP process also appears as the most effective method to improve the mechanical strength. Surface modification is achieved by designing a surface patterning method that uses silver nanoparticle microdeposition to functionalize the material for antibacterial properties. The deposition is followed by a laser sintering process. A series of depositions are performed to achieve the desired deposition conditions and a reproducible deposition line of 20 μm width and between few hundreds of nanometres and one micrometre thick. Profilommetry, SEM and TEM are used to characterize the silver deposition and the substrate microstructure. A finite element simulation has been conducted to describe the thermal effect of the laser treatment process. The modelling results show that the thermal impact from the laser sintering process extends deep into the substrate and thus needs to be controlled in order to avoid any evolution of the previously designed bulk microstructure. This model can then provide a basis to investigate the impact of different input parameters for further process optimization in future applications.

▼ Additive manufacturing (AM) introduces a new era for the fabrication of 3D structures. AM, as an emerging and disruptive manufacturing technology, has the potential to be employed for fabrication of polymeric, metallic, and ceramic structures. Although AM is now being used for commercial applications, there are still many challenges in incorporating high-performance materials into these techniques and employing them to fabricate practical devices. For instance, reduced graphene oxide (RGO) has interesting properties such as high specific surface area and lattice defects with tunable functional groups which make it ideal for different applications. However, there is still a substantial need to introduce reliable manufacturing techniques for RGO-based devices while attaining the utmost performance of graphene-based materials. In this study, a binder-jetting powder-bed AM technique has been employed to fabricate graphene-based structures and devices for energy storage and sensing applications. First, 3D structures of graphene/hydroxyapatite (Hap) based composite with potential applications in bone-implantation were fabricated using AM technique. Hap suffers from lack of sufficient mechanical strength which has limited its application for practical use. The compressive strength of the 3D printed structures were tested and the printing parameters were optimized to improve the mechanical behavior of the specimens. It was shown that at a layer thickness of 125 μm and core binder saturation level of 400%, the mechanical strength of HG4 structures with only 0.4 wt.% of graphene oxide were 70 times more than that of HG0 structures. Our next goal was to print pure graphene-based structures for energy and sensing applications. Hence, graphene oxide was first synthesized through Hummer’s method and then reduced it through thermal and chemical methods to compare their performance for energy applications. The as-obtained thermally and chemically reduced graphene-oxide based powder were both 3D printed and studied accordingly. It was revealed that the gravimetric capacitance of thermally reduced graphene oxide (TRGO) 3D printed electrodes were 3-4 times higher than that of chemically reduced powder. Therefore, TRGO powder was selected for further studies and optimization. In order to improve the performance of 3D printed TRGO based electrodes, a nano palladium dispersion was synthesized and injected into the electrodes after printing. TRGO based decorated with nano palladium particles showed an impressive capacitance of 265 F/g and 700 mF/cm2 at 5 mV/s. This study can introduce a new potential application of AM for the fabrication of graphene-based supercapacitor devices. In addition, a graphene-based humidity sensing devices was also fabricated using powder-bed AM technique. The results obtained from this device were promising and demonstrated a great potential for the use of AM for manufacturing of graphene-based sensor devices.
