Abstract:
Let $ R, S $ be rings with unity, $ M $ a module over $ S $, where $ S $ a commutative ring, and $ f \colon R \rightarrow S $ a ring homomorphism. A ring representation of $ R $ on $ M $ via $ f $ is a ring homomorphism $ \mu \colon R \rightarrow End_S(M) $, where $ End_S(M) $ is a ring of all $ S $-module homomorphisms on $ M $. One of the important properties in representation of rings is the Schur's Lemma. The main result of this paper is partly the generalization of Schur's Lemma in representations of rings on modules over a commutative ring

Abstract:
LetRbe a non-commutative associative ring with unity1≠0, a leftR-module is said to satisfy property (I) (resp. (S)) if every injective (resp. surjective) endomorphism ofMis an automorphism ofM. It is well known that every Artinian (resp. Noetherian) module satisfies property (I) (resp. (S)) and that the converse is not true. A ringRis called a left I-ring (resp. S-ring) if every leftR-module with property (I) (resp. (S)) is Artinian (resp. Noetherian). It is known that a subringBof a left I-ring (resp. S-ring)Ris not in general a left I-ring (resp. S-ring) even ifRis a finitely generatedB-module, for example the ringM3(K)of3×3matrices over a fieldKis a left I-ring (resp. S-ring), whereas its subringB={[α00βα0γ0α]/α,β,γ∈K}which is a commutative ring with a non-principal Jacobson radicalJ=K.[000100000]+K.[000000100]is not an I-ring (resp. S-ring) (see [4], theorem 8). We recall that commutative I-rings (resp S-tings) are characterized as those whose modules are a direct sum of cyclic modules, these tings are exactly commutative, Artinian, principal ideal rings (see [1]). Some classes of non-commutative I-rings and S-tings have been studied in [2] and [3]. A ringRis of finite representation type if it is left and right Artinian and has (up to isomorphism) only a finite number of finitely generated indecomposable left modules. In the case of commutative rings or finite-dimensional algebras over an algebraically closed field, the classes of left I-rings, left S-rings and rings of finite representation type are identical (see [1] and [4]). A ringRis said to be a ring with polynomial identity (P. I-ring) if there exists a polynomialf(X1,X2,…,Xn),n≥2, in the non-commuting indeterminatesX1,X2,…,Xn, over the centerZofRsuch that one of the monomials offof highest total degree has coefficient1, andf(a1,a2,…,an)=0for alla1,a2,…,aninR. Throughout this paper all rings considered are associative rings with unity, and by a moduleMover a ringRwe always understand a unitary leftR-module. We useMRto emphasize thatMis a unitary rightR-module.

We investigate that if R is S-compatible and (S, ω)-Armendariz, then the skew generalized power series ring has same triangulating dimension as R. Furthermore, if R is a PWP ring, then skew generalized power series is also PWP ring.

A ring R is called a left APP-ring if the left annihilator lR(Ra) is right s-unital as an ideal of R for any a ∈ R. Let R be a ring, (S, ≤) be a commutative strictly ordered monoid and ω: S → End (R) be a monoid homomorphism. The skew generalized power series ring [[RS, ≤, ω]] is a common generalization of (skew) polynomial rings, (skew) power series rings, (skew) Laurent polynomial rings, (skew) group rings and Malcev–Neumann Laurent series rings. We study the left APP-property of the skew generalized power series ring [[RS, ≤, ω]]. It is shown that if (S, ≤) is a commutative strictly totally ordered monoid, ω: S→ Aut (R) a monoid homomorphism and R a ring satisfying the descending chain condition on right annihilators, then [[RS, ≤, ω]] is left APP if and only if for any S-indexed subset A of R, the ideal lR(∑a ∈ A ∑s ∈ S Rωs (a)) is right s-unital.

Let R be a ring, S a strictly ordered monoid, and ω : S → End (R) a monoid homomorphism. The skew generalized power series ring R[[S, ω]] is a common generalization of (skew) polynomial rings, (skew) Laurent polynomial rings, (skew) power series rings, (skew) Laurent series rings, and (skew) monoid rings. We characterize when a skew generalized power series ring R[[S, ω]] is left principally quasi-Baer and under various finiteness conditions on R we characterize when the ring R[[S, ω]] is left APP. As immediate corollaries we obtain characterizations for all aforementioned classical ring constructions to be left principally quasi-Baer or left APP. Such a general approach not only gives new results for several constructions simultaneously, but also serves the unification of already known results.

Full text
Abstract:
Thienylenevinylene derived polymers have been extensively investigated for use in electrooptical devices. A precursor route and direct polymerisation methods to soluble thienylenevinylene homopolymers have been developed. These synthetic routes routinely yield little control of the polymer molar mass distribution and require further purification to remove the impurities and small oligomers. In this thesis, a new route to produce soluble polythienylenevinylenes is described via a ring-opening metathesis polymerisation (ROMP) it is extended to the preparation of PPV-PTV copolymers and block copolymers with a well-defined chain structure. Chapter 1 introduces the fundamentals of conjugated polymers and the general principle of the applications in organic light-emitting diodes and organic photovoltaic devices. The synthetic methods used to prepare poly(para-phenylenevinylene)s and poly(thienylenevinylene)s are introduced. Alkene metathesis is described and its use in ROMP examined. Chapter 2 focuses on the preparation and characterisation of poly(3,4-dialkylthienylenevinylene)s. Chapter 3 describes the preparation and characterisation of poly(para-phenylenevinylene-co-3,4-dioctylthienylenevinylene) copolymer. In Chapter 4, the preparation and characterisation of poly(para-phenylenevinylene)-block-poly(thienylenevinylene) copolymer are discussed. An overview of the work in this thesis and the potential for future work are presented in Chapter 5. All the experimental procedures are described in Chapter 6.

Abstract:
For a finite group G we study certain rings called k-S-rings, one for each non-negative integer k, where the 1-S-ring is the centralizer ring of G. These rings have the property that the (k+1)-S-ring determines the k-S-ring. We show that the 4-S-ring determines G when G is any group with finite classes. We show that the 3-S-ring determines G for any finite group G, thus giving an answer to a question of Brauer. We show the 2-characters defined by Frobenius and the extended 2-characters of Ken Johnson are characters of representations of the 2-S-ring of G. We find the character table for the 2-S-ring of the dihedral groups of order 2n, n odd, and classify groups with commutative 3-S-ring.

Abstract:
Poly(arylene ether sulfone)s (PAES) are important commercial polymers and have been extensively studied due to their excellent thermal and mechanical properties. However, some applications are still limited when good solvent resistance and low thermal expansion coefficient are required. There has been a continuous interest in developing new PAES based on new monomers or polymer modifications to obtain new properties or to enhance existing properties. In this dissertation, the synthesis, characterization and structure-property relationship of new 1,4-cyclohexylene ring containing PAESs were comprehensively studied. Different polymerization techniques were used to synthesize polymers with different segmental lengths. The monomer, 4,4'-[trans-1,4-cyclohexanebis(methylene)] bisphenol (CMB), was synthesized and fully characterized. Based on 4,4â -dihydroxy-p-terphenyl (DHTP), 4,4â -dihydroxybiphenyl (DHBP) and the CMB monomer, homopolymer and random copolymers of PAES were prepared with high molecular weights and high glass transition temperatures. Dynamic mechanical analysis (DMA) on these polymers showed multiple sub-Tg relaxations. A large increase in the ultimate elongation was obtained with the CMB and DHTP containing sample, which could be due to the strong sub-Tg relaxations observed from the DMA results. A series of four acid chloride monomers were synthesized and polymerized with phenol terminated PAES oligomers. Solution polymerization and pseudo-interfacial polymerization techniques were used to prepare both bisphenol-A (bis-A) based and DHBP based PAES oligomers. With the incorporation of the trans-1,4-cyclohexylene units, decreases in the glass transition temperatures were observed from both the bis-A based and the DHBP based polymers. However, melting transitions were only observed in the DHBP based trans-1,4-cyclohexylene containing PAESs. Crystallinity was confirmed by differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD). A mechanical property study of the high molecular weight trans-1,4-cyclohexylene containing polymer samples showed moderate ultimate elongation enhancements. A series of PAES-polyester multiblock copolymers were synthesized with both solution method and melt polymerization. In the solution method, phenol terminated PAES oligomers and the acid chloride terminated poly(1,4-cyclohexylenedimethylene terephthalate) (PCT) oligomers were presynthesized and coupled in solution. The molecular weights of the polymer products obtained from the solution method were limited by solubility issues. Melt phase polymerization was employed to obtain high molecular weight polymers. Hydroxy ethoxy terminated PAES oligomers were synthesized and polymerized with 1,4-cyclohexanedimethanol (CHDM) and dimethyl terephthalate (DMT) in the melt. Polymers with high molecular weights were obtained. Tensile test results suggested that the mechanical properties of these polymers were dominated by the PAES components with polyester contents up to 20 wt%. Melting transitions were observed from polymers with higher polyester contents, and these polymers exhibited limited solubility in common organic solvents.

Full text
Abstract:
Part I: Single sized, pure arylene ether macrocycles ranging from 30 to 60 atom ring sizes were synthesized in good yields (up to 83%) by the two component method under high dilution conditions. These macrocycles have unsymmetric structures containing sulfone/ketone or sulfone/phosphine oxide functional groups and have relatively low melting points. The melt ROP of the single sized macrocycles to form poly(arylene ether)s exhibits two stage characteristics: the first stage is very fast, driven by the large entropy difference between cyclics and linears; the second stage is very slow and is diffusion controlled due to the high viscosity created in the first stage reaction. The latter stage leads to incomplete polymerization at the low initiator concentrations (1-3 mol%). At high initiator concentrations (5-7 mol%), 100% conversion is reached due to improved initiator distribution in macrocycles; however, this reduces molecular weights of the polymers. The molecular weight is found to build up very rapidly, independent of conversion, reaction time and type of initiator. The ROP is initiated by CsF and alkali phenoxides. The efficiency of the alkali counterion is generally in the order of Cs+>K+>Na+, while a phenoxide initiator is more efficient than a fluoride initiator. It is also found that the Cs counterion leads to highest degree of crosslinking. The ROP of cyclic oligomeric mixtures is also reported for comparison; the study shows that the molecular weight depends on time and conversion, and that the conversion is sensitive to the content of linear impurities and the average ring size of cyclic mixtures. Part II: Polyrotaxanes are novel polymeric materials comprised of linear polymer molecules and threaded macrocycles with no covalent bond between the two components. With potential movements of the cyclic component and judicious combinations of the two components of different properties, these materials have brought interesting changes of physical properties, such as morphology, crystallinity, solubility, viscosity, etc. In this part of the dissertation, a new family of polyrotaxanes with poly(arylene ether)s as backbones and crown ethers as cyclic components are described. These include linear poly(arylene ether) based polyrotaxanes and hyperbranched poly(ether ether ketone) based polyrotaxanes; both are synthesized via aromatic nucleophilic substitution reactions. Preliminary studies show that these polymers exhibit great enhancement of solubility. The polymers form emulsions in water and methanol which are normally non-solvents for the poly(arylene ether) backbones. In some cases, they are even soluble in water to form a clear solution. The attempted syntheses of polyrotaxanes using aromatic macrocycles described in Part I was not successful, with no indication of threading.

Full text
Abstract:
This thesis examines options for high capacity all optical networks. Specifically optical time division multiplexed (OTDM) networks based on electro-optic modulators are investigated experimentally, whilst comparisons with alternative approaches are carried out. It is intended that the thesis will form the basis of comparison between optical time division multiplexed networks and the more mature approach of wavelength division multiplexed networks. Following an introduction to optical networking concepts, the required component technologies are discussed. In particular various optical pulse sources are described with the demanding restrictions of optical multiplexing in mind. This is followed by a discussion of the construction of multiplexers and demultiplexers, including favoured techniques for high speed clock recovery. Theoretical treatments of the performance of Mach Zehnder and electroabsorption modulators support the design criteria that are established for the construction of simple optical time division multiplexed systems. Having established appropriate end terminals for an optical network, the thesis examines transmission issues associated with high speed RZ data signals. Propagation of RZ signals over both installed (standard fibre) and newly commissioned fibre routes are considered in turn. In the case of standard fibre systems, the use of dispersion compensation is summarised, and the application of mid span spectral inversion experimentally investigated. For green field sites, soliton like propagation of high speed data signals is demonstrated. In this case the particular restrictions of high speed soliton systems are discussed and experimentally investigated, namely the increasing impact of timing jitter and the downward pressure on repeater spacings due to the constraint of the average soliton model. These issues are each addressed through investigations of active soliton control for OTDM systems and through investigations of novel fibre types respectively. Finally the particularly remarkable networking potential of optical time division multiplexed systems is established, and infinite node cascadability using soliton control is demonstrated. A final comparison of the various technologies for optical multiplexing is presented in the conclusions, where the relative merits of the technologies for optical networking emerges as the key differentiator between technologies.

Abstract:
Depuis une dizaine d’années, avec la diversification des appareils connectés (PCs, Tablettes, TVs et Smartphones), l’écosystème Internet s’est drastiquement étendu. Aujourd’hui, 80 % du trafic IP mondial est concentré dans les centres de données. Pour répondre aux problématiques d’échelle des centres de données en terme de densité de bande passante, de consommation énergétique et de coût des interconnections, le développement de nouveaux émetteurs optiques est critique. L’objectif de cette thèse est de proposer et évaluer différentes architectures d’émetteur en photonique sur silicium afin de répondre à la prochaine norme de débit de 400 Gbit/s sur des transmissions de 2 kilomètres. Le modulateur électro-optique sélectionné est le modulateur silicium en anneau résonant. Il possède des avantages non négligeables: faibles dimensions, faible consommation énergétique, et il permet un multiplexage dense en longueurs d’ondes. Durant cette thèse, l’optimisation de l’émetteur optique a été faite de manière progressive: de la jonction active à l’émetteur complet. Cette première étude a identifié les différents compromis à faire sur les paramètres du modulateur en anneau afin de définir ses performances. Un model compact du modulateur a été créé, permettant d’optimiser le composant avec un temps de simulation très réduit. Puis, tout en utilisant le modèle compact, deux architectures d’émetteur ont été étudiées basées sur une architecture classique de la littérature. Elles sont basées sur la mise en série de 8 modulateurs en anneau, chacun modulant une longueur d’onde différente. La différence entre les deux architectures vient du format de modulation utilisé: la première est modulée avec des signaux sur deux niveaux électriques avec des signaux sur 2 niveaux électriques au format d’impulsions en amplitude (PAM-2) à 50 Gbaud ; alors que la deuxième est modulée avec des signaux sur 4 niveaux électriques au format d’impulsions en amplitude (PAM-4). Les deux solutions répondent aux demandes de performances de la norme 400 Gbit/s avec les mêmes points de compromis de fonctionnement. Finalement, de nouvelles architectures d’émetteur optique ont été proposées permettant de réaliser la modulation PAM-4. Contrairement aux solutions précédemment étudiées, ces architectures utilisent en entrée deux flux de bits en parallèle qui sont optiquement combinés pour générer en sortie une modulation PAM-4. Une première solution est basée sur la mise en série de deux modulateurs en anneaux. Cette architecture a été validée avec des caractérisations de transmission optique à 30 Gbit/s avec seulement 1 Vpp de tension de commande. Une seconde solution a ensuite été proposée, elle est basée sur l’utilisation de deux modulateurs mis en parallèle dans un interféromètre Mach Zehnder. De la même manière, des caractérisations de transmission à 30 Gbit/s avec 1.2 Vpp de tension de commande ont permis de valider le fonctionnement de l’architecture
Over the past decade, with the diversification of connected devices (PCs, Tablets, TVs and Smartphones), the Internet ecosystem has drastically extended. Today, 80 % world traffic is concentrated in the data centers where the data rate, the size and the cost is still growing. To address such scaling issues as bandwidth density, energy consumption and cost of the interconnects inside the data centers, the development of new optical transmitters is critical. The aim of this thesis is to propose and evaluate transmitter architectures using silicon photonics technology to address next 400 Gbit/s data rate standard over up to 2 kilometer links. The selected electro-optical modulator is the silicon ring resonator modulator which has substantial benefits: low footprint, low energy consumption and enables dense multiplexing. The optical transmitter architectures evaluations were successively optimized: from the active junction to the complete optical transmitter. This study identified the performances trade-offs impacted by the ring resonator modulator parameters. A compact model was generated to physically optimize the component in a reduced simulation time. Then, using the compact model, two transmitter architectures were studied based on classical architecture. Both are based on eight ring resonator modulators arranged in series modulating eight different wavelengths. The difference is the modulation format: the first one is electrically modulated at 50 Gbaud in 2-levels pulse amplitude modulation (PAM-2) and the second one at 25 Gbaud 4-levels pulse amplitude modulation (PAM-4). The two solutions fit the 400 Gbit/s performances demand with the use of the same trade-offs. Finally, new transmitter architectures were proposed to generate PAM-4 modulation. Unlike the previous architecture, they have in input two parallel bit streams which are optically combined to generate the PAM-4 modulation. The first solution is based on two silicon ring resonator modulator arranged in series. This architecture was validated through 30 Gbit/s transmission characterizations with only 1 Vpp. A second solution was then proposed, based on two silicon ring resonator modulators arranged in parallel in a Mach Zehnder interferometer. In the same way, transmission characterizations at 30 Gbit/s with 1.2 Vpp allows this architecture to be validated

For high-speed (e.g. more than 1 Gbit/s) filtration of network traffic there are available many of proprietary hardware solutions nowadays. But there are also a couple of free licensed projects that are specialized in high-speed packet processing on common hardware. The goal of thesis is to find such projects, verify that there are filtering tools based on these projects, try to filter 10Gbit/s network traffic by these tools and test them against various filtration settings. Implementation of packet filter that could be used for filtration of network traffic up to 10Gbit/s speed should be the output of this thesis.

Abstract:
We built three successive versions of a thermal decomposition cavity ring-down spectrometer and tested their response to explosives. These explosive compound analyzers successfully detected nitroglycerine, 2,4,6-trinitrotoluene (TNT), pentaerythryl tetranitrate, hexahydro-1,3,5-trinitro-s-triazine and triacetone triperoxide (TATP). We determined the pathlength and limits of detection for each, with the best limit of detection being 13 parts per trillion (ppt) of TNT. For most of the explosive tests, the peak height was higher than the expected value, meaning that peroxy radical chain propagation was occurring with each of the explosives and not just the peroxide TATP.

Full text
Abstract:
Metallic residues are distributed heterogeneously onto small-arms range soils from projectile fragmentation upon impact with a target or berm backstop. Incremental Sampling Methodology (ISM) can address the spatially heterogeneous contamination of surface soils on small-arms ranges, but representative kilogram-sized ISM subsamples are affected by the range of metallic residue particle sizes in the sample. This study compares the precision and concentrations of metals in a small-arms range soil sample processed by a puck mill, ring and puck mill, ball mill, and mortar and pestle prior to analysis. The ball mill, puck mill, and puck and ring mill produced acceptable relative standard deviations of less than 15% for the anthropogenic metals of interest (Lead (Pb), Antimony (Sb), Copper (Cu), and Zinc (Zn)), with the ball mill exhibiting the greatest precision for Pb, Cu, and Zn. Precision by mortar and pestle, without milling, was considerably higher (40% to >100%) for anthropogenic metals. Media anthropogenic metal concentrations varied by more than 40% between milling methods, with the greatest concentrations produced by the puck mill, followed by the puck and ring mill and then the ball mill. Metal concentrations were also dependent on milling time, with concentrations stabilizing for the puck mill by 300 s but still increasing for the ball mill over 20 h. Differences in metal concentrations were not directly related to the surface area of the milled sample. Overall, the tested milling methods were successful in producing reproducible data for soils containing metallic residues. However, the effects of milling type and time on concentrations require consideration in environmental investigations.
