Abstract:
En aquest treball s’han estudiat diferents aproximacions a la síntesi de compòsits de nanopartícules magnètiques en matrius de sílice de tipus aerogel o xerogel. Així, s’han obtingut materials amb propietats molt diferents tant pel que fa al seu magnetisme (materials durs o tous), a les seves propietats òptiques (transparents, opacs, anisotròpics) o la seva densitat, i se n’han estudiat algunes de les seves possibles aplicacions magnetoòptiques. Les matrius de sílice en forma de xerogel també s’han fet servir per a estabilitzar, gràcies al confinament, l’ε-Fe2O3, un polimorf metastable d’óxid

Dependence between random variables is studied at various levels in the first part, while the last two chapters are devoted to the construction of bivariate distributions via principal components. Chapter 1 of Preliminaries is devoted to general dependence concepts (Fréchet classes, copulas, and parametric families of distributions). In Chapter 2, we generalize the union and intersection operations of two distance matrices to symmetric nonnegative definite matrices. These operations are shown to be useful in the geometric interpretation of Related Metric Scaling (RMS ), and possibly in other a

In this thesis, we focused on the alternative methodologies that are based on the reconstruction of density matrices. While in DFT several benchmarks can be found in the literature, for the rest of alternative methodologies there were not any comprehensive benchmarks where the quality of the approximated reduce density matrices (RDMs) were analyzed. Thus, in this thesis, we have performed an exhaustive benchmark for the approximations available in the literature that reconstruct the 2- and 3-order RDMs. RDMs provide access to physical magnitudes as the intracule probability density (IPD).

In Markov chain models in finance and healthcare a transition matrix over a certain time interval is needed but only a transition matrix over a longer time interval may be available. The problem arises of determining a stochastic $p$th root of astochastic matrix (the given transition matrix). By exploiting the theory of functions of matrices, we develop results on the existence and characterization of stochastic $p$th roots. Our contributions include characterization of when a real matrix hasa real $p$th root, a classification of $p$th roots of a possibly singular matrix,a sufficient condition

Abstract:
Kirchhoff's laws are well-studied for electrical networks with voltage and current sources, and edges marked by resistors. Kirchhoff's voltage law states that the sum of voltages around any circuit of the network graph is zero, while Kirchhoff's current law states that the sum of the currents along any cutset of the network graph is zero. Given a network, these requirements may be encoded by the circuit matrix and cutset matrix of the network graph. The columns of these matrices are indexed by the edges of the network graph, and their row spaces are orthogonal complements. For (chemical or

Abstract:
In this thesis we deal with binet matrices and the class of signed-graphic matroids which is the class of matroids represented over R by binet matrices. The thesis is divided in three parts. In the first part, we provide the vast majority of the notions used throughout the thesis and some results regarding the class of binet matrices. In this part, we focus on the class of linear and integer programming problems in which the constraint matrix is binet and provide methods and algorithms which solve these problems efficiently. The main new result is that the existing combinatorial methods can no

Abstract:
Transfer RNAs (tRNAs) are key adaptor molecules that mediate decoding of messenger RNAs (mRNAs) into proteins by complementary pairing of their anticodons with mRNA codons. tRNAs that undergo adenosine to inosine editing at the wobble base, or position 34, display expanded codon decoding capacity as inosine enables pairing not only with uridine, but also with cytosine and adenosine. The essential heterodimeric enzyme Adenosine Deaminase Acting on Transfer RNA (ADAT) catalyzes this post-transcriptional modification in eukaryotes and is comprised of subunits ADAT2 and ADAT3.

Abstract:
Kiekvienas mobilus įrenginys turi bateriją, o tai reiškia, kad jų darbo laikas ribotas, kadangi nėra išrasta ilgaamžė baterija. Todėl šiuo metu egzistuojanti problema - kaip pasiekti, kuo ilgesnį mobiliojo įrenginio darbo laiką, be papildomo pakrovimo. Darbo metu naudojamas mobilus įrenginys - delninukas. Iš visų delninuko baterijos energiją suvartojančių komponentų visas dėmesys skiriamas procesoriui ir atminčiai. Tyrimo metu buvo apkrautas procesorius ir atmintis ir stebimi atitinkami baterijos parametrai. Apkrovimui naudojama paprastų ir išretintų matricų saugomų stulpelių metodu daugyba. I
