A domain decomposition method for solving the three-dimensional time-harmonic Maxwell equations discretized by discontinuous Galerkin methods
No full textWe present here a domain decomposition method for solving the three-dimensional time-harmonic Maxwell equations discretized by a discontinuous Galerkin method. In order to allow the treatment of irregularly shaped geometries, the discontinuous Galerkin method is formulated on unstructured tetrahedral meshes. The domain decomposition strategy takes the form of a Schwarz-type algorithm where a continuity condition on the incoming characteristic variables is imposed at the interfaces between neighboring subdomains. A multifrontal sparse direct solver is used at the subdomain level. The resulting domain decomposition strategy can be viewed as a hybrid iterative/direct solution method for the large, sparse and complex coefficients algebraic system resulting from the discretization of the time-harmonic Maxwell equations by a discontinuous Galerkin method
Foreign direct investment in a macroeconomic framework : finance, efficiency, incentives, and distortions
No full textDoes foreign direct investment (FDI) increase domestic investment, or does it provide additional foreign exchange for a pre-existing current account deficit, or some linear combination of the two? The author investigates this question for a group of five Pacific Basin countries and a control group of 11 other developing countries. For the sample of all 16 developing countries, the author finds that FDI does not provide additional balance of payments financing for a pre-existing current account deficit. In the control group of 11 developing countries, FDI is associated with reduced domestic investment - implying that FDI to those countries is simply a close substitute for other capital inflows. For the five Pacific Basin market economies, however, FDI raises domestic investment by the full extent of the FDI inflow. The author finds that FDI has a significantly negative impact on national saving in the sample of all 16 developing countries. For the control group, this negative effect is similar in magnitude to FDI's negative effect on domestic investment - implying a zero effect on the current account. But FDI's negative effect on national saving in the five Pacific Basin developing market economies implies that FDI could have more of a negative effect on the current account than through increased domestic investment alone. The author also investigates the impact of FDI on economic growth in these 16 countries, taking into account distortions in the economies. He estimates reduced-form current account equations, and presents an analytical framework for estimating FDI's effect on economic growth in the presence of incentive-disincentive packages and other economic distortions. He illustrates his framework using indicators of foreign trade and financial distortions. His main conclusion: the effect of FDI differs markedly from one group of countries to another. FDI has a negative effect on economic growth in the control group. It has the same positive effect on growth as domestically financed investment does in the Pacific Basin countries. The main cause for the different effect is the low level of distortion in the Pacific Basin countries.Environmental Economics&Policies,Economic Theory&Research,Foreign Direct Investment,International Terrorism&Counterterrorism,Macroeconomic Management
Interior penalty discontinuous galerkin methods for electromagnetic and acoustic wave equations
No full textIntroduction: In this thesis we present and analyze the numerical approximation of the second
order electromagnetic and acoustic wave equation by the interior penalty (IP)
discontinuous Galerkin (DG) finite element method (FEM). In Part I we focus
on time-harmonic Maxwell source problems in the high-frequency regime. Part
II is devoted to the study of the IP DG FEM for time-dependent acoustic and
electromagnetic wave equations.
We begin by stating Maxwell's equations in time and frequency domain. We
proceed by a variational formulation of Maxwell's equations, and describe the
key challenges that are faced in the analysis of the Maxwell operator. Then,
we review conforming finite element methods to discretize the second order
Maxwell operator. We end this general introduction with some numerical results
to highlight the performance and feasibility of conforming FEM for Maxwell's
equations.
Chapter 2: In this chapter, we introduce and analyze the interior penalty discontinuous
Galerkin method for the numerical discretization of the indefinite time-harmonic
Maxwell equations in high-frequency regime. Based on suitable duality arguments,
we derive a-priori error bounds in the energy norm and the L2-norm. In
particular, the error in the energy norm is shown to converge with the optimal
order O(hminfs;`g) with respect to the mesh size h, the polynomial degree `, and
the regularity exponent s of the analytical solution. Under additional regularity
assumptions, the L2-error is shown to converge with the optimal order O(h`+1).
The theoretical results are confirmed in a series of numerical experiments on
triangular meshes.
The thesis' author's principal contributions are the proof of the L2-error
bound in Section 2.6, and the proof of Lemma 2.4.1.
Chapter 3: We present and analyze an interior penalty method for the numerical discretization
of the indefinite time-harmonic Maxwell equations in mixed form. The
method is based on the mixed discretization of the curl-curl operator developed
in [44] and can be understood as a non-stabilized variant of the approach
proposed in [63]. We show the well-posedness of this approach and derive optimal
a-priori error estimates in the energy-norm as well as the L2-norm. The
theoretical results are confirmed in a series of numerical experiments.
The thesis' author's principal contribution is the proof of the L2-error bound
in Section 3.6.
Chapter 4: The symmetric interior penalty discontinuous Galerkin finite element method
is presented for the numerical discretization of the second-order scalar wave
equation. The resulting stiffness matrix is symmetric positive definite and the
mass matrix is essentially diagonal; hence, the method is inherently parallel
and, leads to fully explicit time integration when coupled with an explicit timestepping
scheme. Optimal a priori error bounds are derived in the energy norm
and the L2-norm for the semi-discrete formulation. In particular, the error
in the energy norm is shown to converge with the optimal order O(hminfs;`g)
with respect to the mesh size h, the polynomial degree `, and the regularity
exponent s of the continuous solution. Under additional regularity assumptions,
the L2-error is shown to converge with the optimal order O(h`+1). Numerical
results confirm the expected convergence rates and illustrate the versatility of
the method.
Chapter 5: We develop the symmetric interior penalty discontinuous Galerkin (DG) method
for the spatial discretization in the method of lines approach of the timedependent
Maxwell equations in second-order form. We derive optimal a-priori
estimates for the semi-discrete error in the energy norm. For smooth solutions,
these estimates hold for DG discretizations on general finite element meshes.
For low-regularity solutions that have singularities in space, the theoretical estimates
hold on conforming, affine meshes. Moreover, on conforming triangular
meshes, we derive optimal error estimates in the L2-norm. Finally, we valuate
our theoretical results by a series of numerical experiments
Standing waves in the Maxwell-Schrödinger equation and an optimal configuration problem
No full textWe study the system of Maxwell-Schro ̈dinger equations
∆u−u−δuψ+f(u)=0, ∆ψ+u2 =0 in RN, where δ>0, u,ψ:RN→R, u,ψ>0, u,ψ→0 as |x|→+∞, and f:R→R,N≥3. We
prove that the set of solutions has a rich structure; more precisely, for any integer K there exists
δK>0 such that, for 0<δ<δK, the system has a solution (uδ,ψδ) with the property that uδ
has K spikes centered at the points Q_δ1,...,Q_δK. Furthermore, for lδ = mini̸=j |Q_δi −Q_δj|, then,
as δ → 0, ((1/lδ) Q_δ1,...,(1/lδ) Q_δK) approaches an optimal configuration for the following maximization problem:

Sensory and motor neuronal networks of the spinal cord
No full textThis body of work is focused upon neuronal networks of the spinal cord which are
involved in processing of sensory information and generation of motor output. It
includes a detailed account of the synaptic organisation, target neurons and
neurotransmitter content of central terminals of various classes of cutaneous and
proprioceptive primary afferent axons. It shows that presynaptic boutons at
axoaxonic synapses, which regulate primary afferent transmission, contain GABA
but that other transmitters such as glycine, neuropeptide Y and acetylcholine may
be co-localised in these structures. The principal conclusion is that certain subtypes
of presynaptic inhibitory interneurons target the terminals of specific types of primary
afferent fibres but the majority of these neurons do not from 'pure' presynaptic
inhibitory systems because many of them also mediate postsynaptic inhibition. A
further series of investigations provides a detailed analysis of the organisation of
monoaminergic axon terminals and the receptors that they act upon. This work
supports the existence of two parallel modes of action for monoamines in the cord; a
diffuse (non-synaptic or paracrine) system and a specific system which acts through
direct synaptic actions on particular target neurons. Serotonin, for example, acts as
a general modulator but also regulates transmission in some pathways selectively.
Amongst the cells that are targeted selectively, are interneurons in reflex pathways
and a class of projection neuron which receives monosynaptic input from
nociceptive primary afferent axons. More recently, the focus has been on the
organization and neurochemical properties of spinal interneurons. Until recently,
there were few satisfactory classifications of spinal interneurons and the relationship
between functional and structural properties of such cells was unclear. A detailed
analysis of interneurons has shown that there is a clear relationship between the
action of a given interneuron (i.e. whether it is inhibitory or excitatory), its axonal
projections and the classes of cell that it targets. In conclusion, the work reported in
this thesis is an attempt to elucidate neuronal circuits which underlie sensory and
motor processes in the spinal cord by applying modern functional anatomical
approaches.SELECTED REVIEW ARTICLES (PEER REVIEWED):

Geschiedenis: Elektrotechniek, jong en onstuitbaar
No full textTijdens de afgelopen lustrumweken, die elders in deze Maxwell uitvoerig staan beschreven, heeft de Electrotechnische Vereeniging haar honderdjarig bestaan gevierd. Ook heeft de faculteit het afgelopen jaar het honderdjarig bestaan van haar opleiding Elektrotechniek gevierd. Twee gedenkwaardige verjaardagen van een mooie opleiding en een mooie vereniging. In de aanloop naar dit moment is in de Maxwell een reeks geschiedenis artikelen verschenen. In deze Maxwell heb ik de eer deze serie af te sluiten met een artikel over de beginjaren van de opleiding Elektrotechniek in Delft en de beginjaren van de Electrotechnische Vereeniging.Electrical Engineering, Mathematics and Computer Scienc
On the Maxwell-Stefan diffusion limit for a reactive mixture of polyatomic gases in non-isothermal setting
No full textIn this article we deduce a mathematical model of Maxwell-Stefan type for a reactive mixture of polyatomic gases with a continuous structure of internal energy. The equations of the model are derived in the diffusive limit of a kinetic system of Boltzmann equations for the considered mixture, in the general non-isothermal setting. The asymptotic analysis of the kinetic system is performed under a reactive-diffusive scaling for which mechanical collisions are dominant with respect to chemical reactions. The resulting system couples the Maxwell-Stefan equations for the diffusive fluxes with the evolution equations for the number densities of the chemical species and the evolution equation for the temperature of the mixture. The production terms due to the chemical reaction and the Maxwell-Stefan diffusion coefficients are moreover obtained in terms of general collision kernels and parameters of the kinetic model
Fasciculicardia Maxwell 1969
No full textGenus <i>Fasciculicardia</i> Maxwell, 1969 <p> <b>Type species.</b> <i>Venericardia subintermedia</i> Suter, 1917 (p. 74) (by original designation). lower–middle Miocene of New Zealand.</p> <p> <b>Diagnosis.</b> Shell small to medium-sized with a subcircular outline. Lunule small, vertical or inclined forward. Right anterior tooth weak; middle tooth prominent and curved; posterior tooth large and narrow. Left anterior tooth small, short and triangular; posterior elongate, narrow and slightly curved. External sculpture of 26 to 32 high, sharp, moderately wide tripartite radial ribs, flanked by very smooth paracostal ribs, and covered by serrated nodes. Third and fourth posterior radial ribs stronger than the rest. Tubular nodes distally opened in posterior area (modified from Maxwell 1969: 173).</p> <p> <b>Included species.</b> <i>F. acanthodes</i> (Suter, 1917) (middle Eocene, New Zealand), <i>F.</i> ? <i>allophyla</i> (Maxwell, 1992) (middle–upper Eocene, New Zealand), <i>F. bartrumi</i> (Fleming, 1950) (middle Eocene, New Zealand), <i>F. benhami</i> (Fleming, 1950) (Oligocene, New Zealand and Australia), <i>F. faceta</i> (Suter, 1917) (upper Oligocene, New Zealand), <i>F. gracilicostata</i> (Tenison-Woods, 1877) (lower Miocene, Australia), <i>F. healyi</i> (Fleming, 1950) (middle Eocene, New Zealand), <i>F. janjukiensis</i> (Chapman & Singleton, 1927) (Oligocene, Australia), <i>F. latissima</i> (Tate, 1886) (Oligocene, Australia), <i>F. nuntia</i> (Marwick, 1928) (lower Eocene, New Zealand and Australia), <i>F. scabrosa</i> (Tate, 1886) (Oligocene, Australia), <i>F. polynema</i> (Tate, 1886) (lower–middle Miocene, Australia).</p> <p> <b>Remarks.</b> According to Maxwell (1969), the sculpture is the main morphological character of <i>Fasciculicardia</i> species. Beu (2006) considered it a subgenus of <i>Glyptoactis</i> Stewart, 1930, but this genus has a more subrectangular outline, a lower number of wider radial ribs and more developed paracostal ribs. The genus is widely distributed from the Eocene–Miocene interval of Australia and New Zealand (Beu & Maxwell 1990).</p>Published as part of <i>Pérez, Damián E. & Del Río, Claudia J., 2017, Systematics of the family Carditidae (Bivalvia: Archiheterodonta) in the Cenozoic of Argentina, pp. 51-84 in Zootaxa 4338 (1)</i> on page 66, DOI: 10.11646/zootaxa.4338.1.3, <a href="http://zenodo.org/record/1035558">http://zenodo.org/record/1035558</a>
