description: This paper empirically analyses the relationship between political leaders’ socioeconomic backgrounds and public budget deficits utilising panel data on 21 OECD countries from 1980 to 2008. Building on sociological, as well as economic, research, we argue that the socioeconomic status of political decision-makers, i.e., presidents or prime ministers, is an important determinant of fiscal budget decisions. Our theory-consistent findings show that the tenures of lower-class leaders—i.e., leaders of low socioeconomic status—are associated with a deficit-to-GDP ratio which is 1.6 percentage points higher than that during tenures of upperclass leaders.

Law and love : the (in)visibility of romantic love in the legal discourse of modern Australian marriage

subject: Marriage law

description: This thesis is about how love, perceived as one of humanity's most powerful emotions, is reflected in law - one of society's most important social discourses. The specific context of this inquiry will be marriage. In the popular discourse of western societies, marriage is steeped in the ideology of romantic love, but to what extent is this view replicated in the legal meaning of marriage? This thesis interrogates four legal episodes which have significantly challenged traditional meanings of marriage in modern Australia, and asks to what extent, and in what form, romantic love features in the construction of those meanings. Marriage has conventionally been understood as a heterosexual relationship between one man and one woman, which has as one of its primary functions the procreation of children. Marriage has also been understood as an economic unit. As such sex, gender, sexuality, procreation, family and economics are all central ideas in marriage. This thesis takes four episodes which question whether sex is part of marriage (R v L); what the relationship between domestic and commercial arrangements are (Garcia); and whether sexual identity, gender and sexuality define marriage (Re Kevin and the same-sex marriage debate). This analysis will show that while romantic love is not altogether invisible in that legal discourse, it does not displace the traditional association of marriage with family, sexual access, procreation and economics. Furthermore when love is visible it is not the liberating, anti-traditional, progressive, radical phenomenon romantic love is often claimed to be; instead we see that love, as per the feminist and queer critiques, is mostly understood as being embedded in very traditional discourses of nature, procreation, domesticity and heterosexuality. Thinking about marriage in the context of love is not a typical legal exercise. Emotions are not usually regarded as relevant for the discipline of law; as such this thesis challenges the positivist rhetoric of law which persistently argues that law is and ought to be separate from emotion. This thesis will show that an emotional inquiry adds much both to the law's understanding of the institution of marriage and to our understanding of the law. This in turn better informs the law to fulfil its regulatory and conflict resolution functions; adds much to our understanding of how law thinks, operates and attributes meanings to social and cultural behaviour; and adds much to the effectiveness of law and its relevance to humanity.

description: To date, few studies have focused on protostellar outflow feedback at scales larger than several parsecs. To address this paucity of research, we investigate the effects of feedback from CO outflow candidates on their parent clouds over $\sim$ 110 deg$^2$ toward the W3/4/5 complex and its surroundings. Our search identified 265 $^{13}$CO clouds with radii being $\sim$ 0.04 -- 17.12 pc. We estimate the turbulent support and potential disruptive effect of the outflow activities through analyzing physical properties of outflow candidates and their host clouds in terms of turbulence and gravitational binding energy. We find:(1) clouds of larger size might be less affected by feedback; (2) the possible scale break is $\gtrsim 4.7$ pc for both turbulent support and potential disruptive effect; (3) if outflows couple to dense gas where stars are forming, for clouds in the Perseus arm, a scale $\lesssim$ 0.2 -- 0.4 pc is sufficient for the energy and momentum injected by outflow activity to maintain turbulence, while for clouds in the Local arm, the scale is $\lesssim$ 0.1 -- 0.2 pc; and (4) for clouds in the Perseus arm, a scale $\lesssim$ 0.3 -- 1.0 pc is needed for outflow activity to potentially disperse material away from the natal clouds, while for clouds in the Local arm, the scale is $\lesssim$ 0.2 -- 0.6 pc.The strength of outflow activity may affect the values in the points (3) and (4). Finally, we find that outflow feedback probably possesses the power to alter the linewidth-size relation.

Isomorphism Checking in GROOVE
Creators: name: Rensink, Arend
Publisher: name: European Association of Software Science and Technology
Year: 2007

description: In this paper we show how isomorphism checking can be used as an effective technique for symmetry reduction in graph-based state spaces, despite the inherent complexity of the isomorphism problem. In particular, we show how one can use /element-based graph certificate mappings/ to help in recognising non-isomorphic graphs.  These are mappings that assign to all elements (edges and nodes) of a given graph a number that is invariant under isomorphism, in the sense that any isomorphism between graphs is sure to preserve this number. The individual element certificates of a graph give rise to a certificate for the entire graph, which can be used as a hash key for the graph; hence, this yields a heuristic to decide whether a graph has an isomorphic representative in a previously computed set of graphs. We report some experiments that show the viability of this method.

Combined Integer and Floating Point Multiplication Architecture(CIFM) for FPGAs and Its Reversible Logic Implementation

description: In this paper, the authors propose the idea of a combined integer and floating point multiplier(CIFM) for FPGAs. The authors propose the replacement of existing 18x18 dedicated multipliers in FPGAs with dedicated 24x24 multipliers designed with small 4x4 bit multipliers. It is also proposed that for every dedicated 24x24 bit multiplier block designed with 4x4 bit multipliers, four redundant 4x4 multiplier should be provided to enforce the feature of self repairability (to recover from the faults). In the proposed CIFM reconfigurability at run time is also provided resulting in low power. The major source of motivation for providing the dedicated 24x24 bit multiplier stems from the fact that single precision floating point multiplier requires 24x24 bit integer multiplier for mantissa multiplication. A reconfigurable, self-repairable 24x24 bit multiplier (implemented with 4x4 bit multiply modules) will ideally suit this purpose, making FPGAs more suitable for integer as well floating point operations. A dedicated 4x4 bit multiplier is also proposed in this paper. Moreover, in the recent years, reversible logic has emerged as a promising technology having its applications in low power CMOS, quantum computing, nanotechnology, and optical computing. It is not possible to realize quantum computing without reversible logic. Thus, this paper also paper provides the reversible logic implementation of the proposed CIFM. The reversible CIFM designed and proposed here will form the basis of the completely reversible FPGAs.

A fuctional [sic] analysis of Cis-elements contributing to developmental regulation of gene expression by the 4CL1 promoter in transgenic tobacco plants
Creators: name: Neustaedter, David A.
Publisher: name: University of British Columbia
Year: 2009

description: It has been widely noted that elucidating the mechanisms by which eukaryotic organisms control the timing and location of the expression of particular genes is one of the central problems of developmental biology. This thesis is intended to contribute to an understanding of the mechanisms by which one promoter, that of the parsley 4-coumarate:CoA ligase 1 (4CL1) gene, directs expression of attached protein-coding sequences in developing tobacco plants. In tobacco, 227 base-pairs of the parsley 4CL1 promoter are sufficient to direct a complex pattern of developmentally-regulated gene expression (Hauffe et. al., 1991). Within this region, six sequences have been identified as possible sites of protein-DNA interaction in parsley cell culture (Ibid). In order to test whether these sequences are cis-elements contributing to the developmental regulation of 4CL1- directed gene expression, these sequences were mutated and the effects on expression of a reporter gene examined in different organs and cells of transgenic tobacco plants. Results discussed in this thesis strongly indicate the presence of at least four developmentally-important elements within the tested sequences. While mutation of each element effected expression quantitatively, each element exhibited different cell- and organ-specificities in its influence on gene expression. The identified elements include both positive and negative regulators of gene expression. Expression patterns directed by the 4CL1 promoter when mutated at multiple sites suggest that the examined elements are in some cases interdependent, requiring other elements in order to function. One element, the footprint 5/6 element, may play a particularly important role in these interactions. Taken together, these observations identify developmentally-important cis-elements in the 4CL1-promoter and provide insights into the mechanisms by which they function.

description: A local artificial neural network (LANN) framework is developed for turbulence modeling. The Reynolds-averaged Navier-Stokes (RANS) unclosed terms are reconstructed by artificial neural network (ANN) based on the local coordinate system which is orthogonal to the curved walls. We verify the proposed model for the flows over periodic hills. The correlation coefficients of the RANS unclosed terms predicted by the LANN model can be made larger than 0.96 in an a priori analysis, and the relative error of the unclosed terms can be made smaller than 18%. In an a posteriori analysis, detailed comparisons are made on the results of RANS simulations using the LANN and Spalart-Allmaras (SA) models. It is shown that the LANN model performs better than the SA model in the prediction of the average velocity, wall-shear stress and average pressure, which gives the results that are essentially indistinguishable from the direct numerical simulation (DNS) data. The LANN model trained in low Reynolds number Re = 2800 can be directly applied in the cases of high Reynolds numbers Re = 5600, 10595, 19000, 37000 with accurate predictions. Furthermore, the LANN model is verified for flows over periodic hills with varying slopes. These results suggest that the LANN framework has a great potential to be applied to complex turbulent flows with curved walls.

A basic tool for the modeling of Marked-Controlled Reconfigurable Petri Nets
Creators: name: Llorens, Marisa
name: Oliver, Javier
Publisher: name: European Association of Software Science and Technology
Year: 2007

description: In previous studies, we have introduced marked-controlled net rewriting systems and a subclass of these called marked-controlled reconfigurable Petri nets. In a marked-controlled net rewriting system, a system configuration is described as a Petri net, and a change in configuration is described as a graph rewriting rule. A marked-controlled reconfigurable Petri net is a marked-controlled net rewriting system where a change in configuration amounts to a modification in the flow relations of the places in the domain of the involved rule in accordance with this rule, independently of the context in which this rewriting applies. In both models, the enabling of a rule not only depends on the net topology, but also depends on the net marking according to control places. Even though the expressiveness of Petri nets and marked-controlled reconfigurable Petri nets is the same, with marked-controlled reconfigurable Petri nets, we can easily and directly model concurrent and distributed systems that change their structure dynamically. In this article, we present MCReNet, a tool for the modeling and verification of marked-controlled reconfigurable Petri nets.

description: The Beamline for Advanced diCHroism (BACH) of the Istituto Officina dei Materiali-Consiglio Nazionale delle Ricerche (IOM-CNR), operating at Elettra synchrotron in Trieste (Italy), works in the extreme ultra violet (EUV)-soft X-ray photon energy range with selectable light polarization, high energy resolution, brilliance and time resolution. The beamline offers a multi-technique approach for the investigation of the electronic, chemical, structural, magnetic, and dynamical properties of materials. Recently one of the three end-stations has been dedicated to experiments based on electron transfer processes at the solid/liquid interfaces and during photocatalytic or electrochemical reactions. Suitable cells to perform soft X-ray spectroscopy in the presence of liquids and reagent gases at ambient pressure were developed. Here we present two types of static cells working in transmission or in fluorescence yield, and an electrochemical flow cell which allows to carry out cyclic voltammetry in situ, electrodeposition on a working electrode (WE) and to study chemical reactions in-operando conditions. Examples of X-ray absorption spectroscopy (XAS) measurements performed in ambient conditions and during electrochemical experiments in liquid are presented.

description: The multifrontal method is widely used for the numerical solution of large sparse symmetric linear systems of equations. In this report, we discuss the design and implementation of a new multifrontal code HSL_MA97. Our motivation for the new code is discussed along with the key design features. HSL_MA97 is for real and complex problems and is designed to be efficient for both positive definite and indefinite systems. HSL_MA97 can be run in serial or in a shared memory environment using OpenMP. An important feature is that in parallel it offers bit-compatible solutions. Numerical results are presented for a range of problems from practical applications and comparisons are made with existing codes. Future plans for HSL_MA97 are outlined.

description: Adhesive  high-level replacement (HLR) systems have been recently introduced as a new categorical framework for double pushout transformations. Algebraic high-level nets combine algebraic specifications with Petri nets to allow the modelling of data, data flow and data changes within the net.

In this paper, we show that algebraic high-level schemas and nets fit well into the context of weak adhesive HLR categories. This allows us to apply the developed theory also to algebraic high-level net transformations.

description: Convolutional Neural Networks (CNN) has been extensively studied for Hyperspectral Image Classification (HSIC) more specifically, 2D and 3D CNN models have proved highly efficient in exploiting the spatial and spectral information of Hyperspectral Images. However, 2D CNN only considers the spatial information and ignores the spectral information whereas 3D CNN jointly exploits spatial-spectral information at a high computational cost. Therefore, this work proposed a lightweight CNN (3D followed by 2D-CNN) model which significantly reduces the computational cost by distributing spatial-spectral feature extraction across a lighter model alongside a preprocessing that has been carried out to improve the classification results. Five benchmark Hyperspectral datasets (i.e., SalinasA, Salinas, Indian Pines, Pavia University, Pavia Center, and Botswana) are used for experimental evaluation. The experimental results show that the proposed pipeline outperformed in terms of generalization performance, statistical significance, and computational complexity, as compared to the state-of-the-art 2D/3D CNN models except commonly used computationally expensive design choices.

description: We present an analytical framework to study the escape rate from a metastable state under the influence of two external multiplicative cross-correlated noise processes. Starting from a phenomenological stationary Langevin description with multiplicative noise processes, we have investigated the Kramers' theory for activated rate processes in a nonequilibrium open system (one-dimensional in nature) driven by two external cross-correlated noise processes which are Gaussian, stationary and delta correlated. Based on the Fokker-Planck description in phase space, we then derive the escape rate from a metastable state in the moderate to large friction limit to study the effect of degree of correlation on the same. By employing numerical simulation in the presence of external cross-correlated additive and multiplicative noises we check the validity of our analytical formalism for constant dissipation, which shows a satisfactory agreement between both the approaches for the specific choice of noise processes. It is evident both from analytical development and the corresponding numerical simulation that the enhancement of rate is possible by increasing the degree of correlation of the external fluctuations.

description: We aim to increase the flexibility at which a data worker can choose the right tool for the job, regardless of whether the tool is a code library or an interactive graphical user interface (GUI). To achieve this flexibility, we extend computational notebooks with a new API mage, which supports tools that can represent themselves as both code and GUI as needed. We discuss the design of mage as well as design opportunities in the space of flexible code/GUI tools for data work. To understand tooling needs, we conduct a study with nine professional practitioners and elicit their feedback on mage and potential areas for flexible code/GUI tooling. We then implement six client tools for mage that illustrate the main themes of our study findings. Finally, we discuss open challenges in providing flexible code/GUI interactions for data workers.

description: We develop strong lower bounds for the span of the projective Stiefel manifolds $X_{n,r}=O(n)/(O(n-r)\times \mathbb Z/2)$, which enable very accurate (in many cases exact) estimates of the span. The technique, for the most part, involves elementary stability properties of vector bundles. However, the case $X_{n,2}$ with $n$ odd presents extra difficulties, which are partially resolved using the Browder-Dupont invariant. In the process, we observe that the symmetric lift due to Sutherland does not necessarily exist for all odd dimensional closed manifolds, and therefore the Browder-Dupont invariant, as he formulated it, is not defined in general. We will characterize those $n$'s for which the Browder-Dupont invariant is well-defined on $X_{n,2}$. Then the invariant will be used in this case to obtain the lower bounds for the span as a corollary of a stronger result.

description: A first principles density functional based linear response theory (the so called Density Functional Perturbation theory \cite{dfpt}) has been combined separately with two recently developed formalism for a systematic study of the lattice dynamics in disordered binary alloys. The two formalisms are the Augmented space recursion (ASR) and the Itinerant coherent potential approximation (ICPA). The two different theories (DFPT-ASR and DFPT-ICPA) systematically provides a hierarchy of improvements upon the earlier single site based theories (like CPA etc.) and includes non-local correlations in the disorder configurations. The formalisms explicitly take into account fluctuations in masses, force constants and scattering lengths. The combination of DFPT with these formulation helps in understanding the actual interplay of force constants in alloys. We illustrate the methods by applying to a fcc Fe$_{50}$Pd$_{50}$ alloy.

Event Structure Semantics for Dynamic Graph Grammars

description: Dynamic graph grammars (DGGs) are a reflexive extension of Graph Grammars that have been introduced to represent mobile reflexive systems and calculi at a convenient level of abstraction. Persistent graph grammars (PGGs) are a class of graph grammars that admits a fully satisfactory concurrent semantics thanks to the fact that all so-called asymmetric conflicts (between items that are read by some productions and consumed by other) are avoided. In this paper we introduce a slight variant of DGGs, called persistent dynamic graph grammars (PDGGs), that can be encoded in PGGs preserving concurrency. Finally, PDGGs are exploited to define a concurrent semantics for the Join calculus enriched with persistent messaging (if preferred, the latter can be naively seen as dynamic nets with read arcs).

description: As a first step at developing a theory of noncommutative nonlinear elliptic partial differential equations, we analyze noncommutative analogues of Laplace's equation and its variants (some of the them nonlinear) over noncommutative tori. Along the way we prove noncommutative analogues of many results in classical analysis, such as Wiener's Theorem on functions with absolutely convergent Fourier series, and standard existence and non-existence theorems on elliptic functions. We show that many many classical methods, including the Maximum Principle, the direct method of the calculus of variations, the use of the Leray-Schauder Theorem, etc., have analogues in the noncommutative setting.

description: One of the main challenges of the sintering of sterling silver is the phenomenon of swelling causing de-densification and a considerable reduction of the sintering kinetics. This swelling phenomenon opposes sintering and it needs to be addressed by a well-controlled processing atmosphere. In the present study, the pressure-less sintering behavior of sterling silver is investigated in air, argon, and vacuum. A specially modified spark plasma sintering mold is designed to study the pressure-less sintering of sterling silver in a high vacuum environment. The conducted analysis is extended to the new constitutive equations of sintering enabling the prediction of the swelling phenomena and the identification of the internal equivalent pressure that opposes the sintering.
On the Invariance of Li-Yorke Chaos of Interval Maps

description: In their celebrated "Period three implies chaos" paper, Li and Yorke proved that if a continuous interval map f has a period 3 point then there is an uncountable scrambled set S on which f has very complicated dynamics. One question arises naturally: Can this set S be chosen invariant under f? The answer is positive for turbulent maps and negative otherwise. In this note, we shall use symbolic dynamics to achieve our goal. In particular, we obtain that the tent map T(x) = 1 - |2x-1| on [0, 1] has a dense uncountable invariant 1-scrambled set which consists of transitive points.

Spectral shape of the UV ionizing background and HeII absorption at redshifts 1.8 < z < 2.9

description: The shape of the UV ionizing background is reconstructed from optically thin metal absorption-line systems identified in spectra of HE2347-4342, Q1157+3143, and HS1700+6416 in the redshift interval 1.8 < z < 2.9. The systems are analyzed by means of the Monte Carlo Inversion method completed with the spectral shape recovering procedure. The UVB spectral shape fluctuates at 2.4 < z < 2.9 mostly due to radiative transfer processes in the clumpy IGM. At z < 1.8, the IGM becomes almost transparent both in the HI and HeII Lyman continua and the variability of the spectral shape comes from diversity of spectral indices describing the QSO/AGN intrinsic radiation. At z > 2.4, the recovered spectral shapes show intensity depression between 3 and 4 Ryd due to HeII Ly-alpha absorption in the IGM clouds (line blanketing) and continuous medium (true Gunn-Petersen effect). The mean HeII Ly-alpha opacity estimated from the depth of this depression corresponds within 1-2sigma to the values directly measured from the HI/HeII Ly-alpha forest towards the quasars studied. The observed scatter in eta = N(HeII)/N(HI) and anti-correlation between N(HI) and eta can be explained by the combined action of variable spectral softness and differences in the mean gas density between the absorbing clouds. Neither of the recovered spectral shapes show features which can be attributed to the putative input of radiation from soft sources like starburst galaxies.

Strategic airline alliance : modelling and empirical analysis
Creators: name: Park, Jong-Hun
Publisher: name: University of British Columbia
Year: 2009

description: During the past years, major airlines have extended their service networks primarily via strategic alliances with other airlines. The purpose of this thesis is to investigate the effects of strategic alliances on market outcomes and economic welfare. Chapter 2 reviews the history of alliances, examines their current status, and discusses the future evolution of alliances. Based on analysis of 46 alliances, it seems likely that strategic alliances will continue to expand and form global airline networks. Consequently, a limited number of future global networks will likely be formed by alliances composed of airlines from each continent. Chapter 3 develops theoretical models to examine the effects on firms' outputs and profits, and economic welfare of different types of alliances: "complementary" and "parallel" alliances. The complementary alliance refers to the case where two carriers link their networks to feed traffic to each other. The parallel alliance refers to collaboration between two carriers competing on the same route. We find that the two types have different effects on total output and consumer surplus. We identify sufficient conditions under which each type of alliance improves total welfare. Empirical test results confirm the theoretical predictions concerning partners' outputs and total output. Chapter 4 empirically examines the effects on air fares, passenger volume, service quality, and partners' stock values and traffic of four major alliances in the North Atlantic market: British Airways-USAir, Delta-Sabena-Swissair, KLM-Northwest, and Lufthansa-United. Equilibrium traffic increases by an average of 35,998 passengers annually, while equilibrium air fares decrease, on average, by $41 on alliance routes. As a result, consumer benefits increase by $130 million, a 12 per cent increase over the without-all iance consumer surplus level during the post-alliance period. Schedule delay times are also reduced, owing to the alliances. Partners' stock values are positively affected by alliance announcements and by alliance operations. Most partners have experienced greater traffic increases on alliance routes than those on non-alliance routes. Government agents should be cautious before granting antitrust immunity to would-be parallel alliance partners. However, the international aviation market could become more competitive by approving more complementary alliances and promoting competition among alliance groups.
Resolving the A_{FB}^b puzzle in an extra dimensional model with an extended gauge structure

description: It is notorious that, contrary to all other precision electroweak data, the forward-backward asymmetry for b quarks $A_{FB}^b$ measured in Z decays at LEP1 is nearly three standard deviations away from the predicted value in the Standard Model; significant deviations also occur in measurements of the asymmetry off the Z pole. We show that these discrepancies can be resolved in a variant of the Randall-Sundrum extra-dimensional model in which the gauge structure is extended to $SU(2)_L \times SU(2)_R \times U(1)_X$ to allow for relatively light Kaluza-Klein excitations of the gauge bosons. In this scenario, the fermions are localized differently along the extra dimension, in order to generate the fermion mass hierarchies, so that the electroweak interactions for the heavy third generation fermions are naturally different from the light fermion ones. We show that the mixing between the Z boson with the Kaluza-Klein excitations allows to explain the $A_{FB}^b$ anomaly without affecting (and even improving) the agreement of the other precision observables, including the $Z \to bb$ partial decay width, with experimental data. Some implications of this scenario for the ILC are summarized.

Search for CP Violation in Neutral D Meson Cabibbo-suppressed Three-body Decays

description: Using 385 fb^-1 of e^+e^- collision data collected at center-of-mass energies around 10.6 GeV, we search for time-integrated CP violation in the singly Cabibbo-suppressed decays D0/D0bar --> pi^- pi^+ pi^0 and D0/D0bar --> K^- K^+ pi^0. Our model-independent and model-dependent analyses show no evidence of CP violation in these decays. The intermediate amplitudes include well-defined flavor states [e.g., rho(770)^+- pi^-+, K*(892)^+- K^-+] and CP-odd eigenstates [e.g., rho(770)^0 pi^0, phi(1020) pi^0]. With the null results of the previous analyses for CP-even eigenstates D0/D0bar --> K^+ K^- and D0/D0bar --> pi^+ pi^-, we conclude that any CP violation in the singly Cabibbo-suppressed charm decays occurs at a rate which is not larger than a few percent. These results are in accord with the Standard Model predictions, and provide constraints on some models beyond the Standard Model.

Lepton Flavor Violating Decays as Probes of Neutrino Mass Spectra and Heavy Majorana Neutrino Masses

description: We investigate the lepton flavor violating (LFV) rare decays in the supersymmetric minimal seesaw model in which the Frampton-Glashow-Yanagida ansatz is incorporated. The branching ratio of $μ\to e γ$ is calculated in terms of the Snowmass Points and Slopes (SPS). We find that the inverted mass hierarchy is disfavored by all SPS points. In addition, once the ratio of BR$(τ\to μγ)$ to BR$(μ\to e γ)$ is measured, one may distinguish the normal and inverted neutrino mass hierarchies, and confirm the masses of heavy right-handed Majorana neutrinos by means of the LFV processes and the thermal leptogenesis mechanism. It is worthwhile to stress that this conclusion is independent of the supersymmetric parameters.

description: This work addresses the two great challenges of the spark plasma sintering (SPS) process: the sintering of complex shapes and the simultaneous production of multiple parts. A new controllable interface method is employed to concurrently consolidate two nickel gear shapes by SPS. A graphite deformable sub-mold is specifically designed for the mutual densification of the both complex parts in a unique 40 mm powder deformation space. An energy efficient SPS configuration is developed to allow the sintering of a large-scale powder assembly under electric current lower than 900 A. The stability of the developed process is studied by electro-thermal-mechanical (ETM) simulation. The ETM simulation reveals that homogeneous densification conditions can be attained by inserting an alumina powder at the sample/punches interfaces enabling the energy efficient heating and the thermal confinement of the nickel powder. Finally, the feasibility of the fabrication of the two near net shape gears with a very homogeneous microstructure is demonstrated.
