Full textAbstract:
Cytomegalovirus is an important human pathogen causing life-threatening and debilitating disorders in some immunocompromised individuals. This double-stranded DNA betaherpesvirus is one of the largest and most complex viruses which establishes latency in the host. Treatment available for symptomatic patients is limited and development of new antiviral strategies is highly desired. Understanding of the virulence and pathogenesis of HCMV requires functional analysis of at least 164 gene products. Due to the species-specificity of HCMV and its inability to replicate in animals, functional analysis of HCMV encoded gene products relies on studies of animal CMVs in their natural hosts. Murine CMV (MCMV) shares a high degree of sequence homology with HCMV and has a similar biology in causing acute and latent infection and disease in mice. Analysis of gene function became more practical with the availability of MCMV cloned into a bacterial artificial chromosome (BAC) plasmid. Phenotypic characterisation of recombinant viruses disrupted in the M34 or M35 ORF, the homologues of HCMV UL34 and UL35 ORF respectively, is presented here. Infectious viruses reconstructed from the mutated BAC plasmids, the mM34 and mM35, had the expected genome rearrangements as indicted by restriction enzyme analysis, PCR and partial sequencing. In vitro, mM34 and mM35 viruses were attenuated in their replication when inoculated at a low and a high multiplicity of infection when compared to the parental virus. Similarly, these viruses were severely restricted in their replication in immunodeficient SCID mice and did not kill mice up to 28 days post-inoculation. Comparison of the predicted M34 and M35 gene products with related betaherpesviruses suggests that the M34 protein plays a role in transcriptional regulation of viral replication and the M35 protein is a component of the tegument.

Full textAbstract:
This thesis reports the characterisation of a novel outer membrane protein (OMP)
from M. catarrhalis, designated M35, with a molecular mass of 36.1 kDa. This protein is
structurally homologous to classic Gram-negative porins, such as OMP C from E. coli and
OMP K36 from K. pneumoniae, with a predicted structure of 8 surface loops connecting 16
antiparallel -sheets. Comparison of the DNA sequences of the M35 genes from 18 diverse
clinical isolates showed that the gene was highly conserved (99.6-100 % of nucleotides)
with only one isolate (ID78LN266) having base variations that resulted in amino acid
substitutions.
A single amino acid mutation in the 3rd external loop of M35 in isolate ID78LN266
significantly affected antibody recognition, indicating that loop 3 contains an immunodominant
B-cell epitope. The reduction in antibody-binding to M35 from ID78LN266
was similar to that caused by complete removal of loop 3. Since loop 3 folds into the porin
channel in the classic structure, the antibody specificity to loop 3 was hypothesised to be
a potential mechanism for evasion of host immune responses targeted to M35, potentially
explaining the high degree of conservation across isolates.
A series of recombinant proteins were constructed to analyse the binding to M35 of
antibodies specificity for loop 3 or the remainder of the protein. It was found that loop 3-
specific antibodies were not able to bind to M35 on the surface of M. catarrhalis and
that this corresponds both with a lack of ability to enhance opsonophagocytosis in vitro
and bacterial clearance in vivo. Additionally, antibodies raised against a version of M35
lacking loop 3 and M35 from the variant isolate ID78LN266 were both no less effective
than the full consensus M35 by both these measures. It therefore appears that while the
majority of antibodies raised against M35 are specific for loop 3 these antibodies do not
mediate anti-M. catarrhalis actions.
Two deletion mutant strains of M. catarrhalis that do not contain the outer membrane
protein M35 were created by insertional inactivation of the M35 gene. Growth comparisons
between these mutant strains and their wildtype parent strains initially led to the
hypothesis that M35 is necessary for efficient glutamic acid uptake by M. catarrhalis,
however this hypothesis was later shown to be incorrect. Efficient uptake of glutamic acid
seemed to be mediated by a novel 40 kDa protein that was up-regulated in the deletion
mutant strains, presumably to compensate for the lack of M35. M35 was also found to
be essential for in vivo survival of M. catarrhalis in the nasal cavities of mice, indicating
that it is an essential functional protein for colonisation of the mucosal surface.

The heat transfer between plasma and a solid occurs mostly due the radiation and the collision of the particles on the material surface, heating the material from the surface to the bulk. The thermal gradient inside the sample depends of the rate of particles collisions and thermal conductivity of the solid. In order to study that effect, samples of AISI M35 steel, with 9,5 mm X 3,0 mm (diameter X thickness) were quenched in resistive furnace and tempereds in plasma using the plane configuration and hollow cathode, working with pressures of 4 and 10 mbar respectively. Analyzing the samples microstructure and measuring the hardness along the transversal profile, it was possible to associate the tempered temperature evaluating indirectly the thermal profile. This relation was obtained by microstructural analyzes and through the hardness curve x tempered sample temperature in resistive furnace, using temperatures of 500, 550, 600, 650 and 700?C. The microstructural characterization of the samples was obtained by the scanning electron microscopy, optic microscopy and X-ray diffraction. It was verified that all samples treated in plasma presented a superficial layer, denominated affected shelling zone, wich was not present in the samples treated in resistive furnace. Moreover, the samples that presented larger thermal gradient were treated in hollow cathode with pressure of 4 mbar

A fim de estudar esse efeito, amostras de a?o AISI M35, com 9,5 mm X 3,0 mm (di?metro X espessura) foram temperadas em forno resistivo e revenidas em plasma, nas configura??es c?todo planar e c?todo oco, com press?es de trabalho de 4 e 10 mbar, para ambas as configura??es. Analisando a microestrutura das amostras e medindo as durezas ao longo do perfil transversal pode-se associar ? temperatura de revenido avaliando indiretamente o perfil t?rmico. Essa rela??o foi obtida atrav?s de an?lise microestrutural e da curva dureza x temperatura de amostras revenidas em forno resistivo, utilizando temperaturas de 500, 550, 600, 650 e 700?C.

Lors de travaux antérieurs, un bio-ingrédient permettant la bioconservation du saumon fumé à froid et ayant une forte activité anti-Listeria fut développé et caractérisé. Il consiste en un milieu de culture fermenté par C. divergens M35 et contenant la bactériocine produite par la souche, soit la divergicine M35. Par contre, les conditions de production actuelles ne permettent pas une utilisation efficace et rentable de ce bio-ingrédient. L'objectif de ce travail est de répondre à ces problématiques. Dans un premier temps, un milieu de culture de grade alimentaire favorisant une forte et rapide croissance de C. divergens M35 et stimulant la production de la divergicine a été développé. Un criblage de différentes sources d'azote, de carbone et de sels a permis de déterminer que la mélasse de canne et le sucre de table (saccharose) sont les sources de carbone de choix, la source d'azote préférentielle reste l'extrait de levure et que l'acétate de sodium stimule la production en bactériocines. Ce milieu fut testé en fermenteur de 30L afin d'évaluer l'effet de la mise à l'échelle. Le milieu créé permet d'atteindre une biomasse de 9,04 log(UFC/mL) et une activité de 1,3X10⁵ AU/mL en 7h. Il s'agit d'une amélioration significative quant à la performance, mais aussi au coût du milieu de culture (0,89$/L) en comparaison à la référence, le milieu MRS (7$/L). Dans un deuxième temps, il a été démontré que le séchage par atomisation est bien plus efficace que la lyophilisation afin de produire un bio-ingrédient biologiquement stable. Le séchage par atomisation permet d'obtenir un bio-ingrédient sec possédant une viabilité de 9,85 log(UFC/g) et une activité anti-Listeria de 1,6X10⁶ AU/g. Ce procédé permet d'avoir une production rentable du bio-ingrédient M35.

Full textAbstract:
Somatically heritable change in regional chromatin structure leading to transcriptional inactivation is observed in a variety of organisms. Euchromatic and heterochromatic domains have been proposed to be formed and maintained by the action of nonhistone chromosomal proteins that either bind directly to DNA or are members of chromatin binding protein complexes. The nonhistone chromosomal proteins M31 and M32 are candidate inducer or maintenance genes of repressed chromatin states in the mouse. I have investigated M31 gene organization and M31 and M32 gene expression to further examine the possible role of these genes in the formation or maintenance of heterochromatic domains. Investigation of the organization of the M31 gene reveals that at least five M31 transcripts are produced by alternative splicing of 9 exons and/or premature termination with polyadenylation. Several transcripts are present before cytologically visible heterochromatin is detected, suggesting that the products of these transcripts have a role in the formation of heterochromatic domains. M32 produces only one transcript whose tissue pattern of expression is similar to that of M31.

Full textAbstract:
Moral licensing is a cognitive bias, which enables individuals to behave immorally without threatening their self-image of being a moral person. We investigate this phenomenon in a cross-cultural marketing context. More specifically, this paper addresses the questions (i) how big moral licensing effects typically are and (ii) which factors systematically influence the size of this effect. We approach these questions by conducting a meta-analysis and a meta-regression. Based on a random effects model, the point estimate for the generalized effect size Cohen's d is 0.319 (SE = 0.046; N = 106). Results of a meta-regression advance theory, by showing for the first time that both cultural background and type of comparison explain a substantial amount of the total variation of the effect size of moral licensing. Marketing practitioners wishing to capitalize on moral licensing effects should therefore consider cross-cultural difference, since marketing measures building on this effect may lead to different revenues in different countries.

Full textAbstract:
Italian artists working in eighteenth-century Britain played a significant role in the country's developing interest in the fine arts. The contributions of artists arriving before mid-century, including Pellegrini, Ricci, and Canaletto, have been noted, but the presence of a larger number of Italians from mid-century is seldom acknowledged. Increasing British wealth and attention to the arts meant more customers for immigrant Italian artists. Bringing with them the skills for which they were renowned throughout Europe, their talents were valued in Britain. Many stayed for prolonged periods, raising families and becoming active members in the artistic community. In a thriving economy, they found opportunities to produce innovative works for a new clientele, devising histories, landscapes, portraits, and prints to entice buyers. The most successful were accomplished networkers, maintaining cordial relationships with British artists and cultivating a variety of patrons. They influenced others through teaching, through formal and informal exchanges with colleagues, and through exhibition of their works that could be studied and emulated.

Full textAbstract:
The 1909-1918 era can be regarded as the formative years of MI5, as it developed from a small counter-espionage bureau into an established security intelligence agency. MI5 had two main roles during this period; counter-espionage, and advising the War Office on how to deal with the police and the civilian population, particularly aliens. Most of the existing literature tends to focus on the development of MI5 as a whole and pays little attention to the six individual branches that constituted MI5 by the armistice. Recently released MI5 documents in The National Archives (rnA) make it possible to examine MI5 at the micro level and set out the intimate workings of its six branches. The study examines the evolution of MI5 from its formation in October 1909 to the end of the First World War in November 1918, paying particular attention to three questions. First, what did a map of the structure of the MI5 organisation look like and "how" did it develop during these years? Secondly, "why" did it develop as it did? Thirdly, "how effective" was MI5 throughout this period? MI5 began as a one-man affair in 1909, tasked with the limited remit of ascertaining the extent of Gemlan espionage in Britain and an uncertain future. By the armistice MI5's role had expanded considerably and it had begun to develop into an established security intelligence agency, with 844 personnel spread over six branches covering the investigation of espionage, prevention, records, ports and travellers, overseas, and alien workers. This study suggests that the main driver of these developments, if one key factor can be singled out, was the changing perception of the nature of the threat posed by German espionage. However, because some within official circles equated all forms of opposition to Government policy with support for Germany, increasing attention also began to be paid to the possibility that industrial umest, pacifists and others who opposed the Government might actually be being directed by a German "hidden hand". From 1917 onwards MI5's development was driven by a conviction that it had defeated German espionage, such that Germany had switched its efforts to promoting Bolshevism and other forms of umest in order to undermine British society. However, MI5's activities were restricted to investigating if there was really any enemy influence behind such things, while Special Branch was to focus on labour unrest generally. This study makes an original and useful contribution to knowledge in three noteworthy respects. First, it sets out probably the most detailed description of MI5's organisational structure available. Secondly, it poses the stimulating question of "how to measure" the effectiveness of a counter-espionage agency? Thirdly, it suggests that, contrary to claims that Vemon Kell was an "empire builder" who wanted a greater role in labour intelligence, Kell felt it appropriate that MI5's activities should be restricted to the investigation of cases of peace propaganda and sedition that arose from enemy activities and did not actually want MI5 to assume a broader role in labour intelligence at that time.

Full textAbstract:
Globular Clusters contain very old metal-poor stars in different evolutionary stages evolved from the same primordial cloud. Signatures of atomic in stellar interiors are studied in the metal-poor GC M30. Furthermore, traces of cluster internal pollution depleting alpha elements e.g. Mg & O are also found through high precision spectroscopy, which favors the existence of multiple stellar populations within a Globular Cluster. In this work, I use spectroscopic observations of 177 sample stars using the multi object spectrograph GIRAFFE and increasing the initial size of 12 of Scheutwinkel (2018) by 13 new UVES spectrograph sample stars of the Globular Cluster M30 ([Fe/H] = -2.3). The abundances of Fe, Ti, Mg & Ba (GIRAFFE) and Fe, Na, Al & Mg (UVES) are derived through the graphical spectrum analysis program SIU with VI broadband photometric stellar input parameters. The underlying line-formation theory is in LTE and uses 1-dimensional hydrostatic plan-parallel MAFAGS atmospheres with mixing length convection. We confirm an Al-Mg anti-correlation (Spearman ϱs= -0.583) and a correlation (Spearman ϱs= 0.641) between Al-Na in RGB stars as a direct result of being the partner elements of the depleted alpha elements Mg & O caused through NeNa, ON and MgAl cycles. We find similar element ratios [X/Fe] as Carretta et al. (2018) & O‘Malley et al. (2018) favoring the prior existence of multiple stellar populations within M30. Furthermore, we detected a signifcant restoration of abundances in the elements Fe, Mg & Ba towards RGB stars. Fe, Mg and Ti are matching the predictions of the diffusion model T5.8 (Richard et al. 2005) reasonably well. For Ba, we have no current atomic diffusion modeling, so the validation of the results is not possible. The trend of Ti is v-shaped presumably due to stronger radiative accelaration effects for this element. Overall our relative abundance trends are consistent with other Globular Cluster studies by Gruyters et al. (2013&2016), Korn et al. (2007) & Lind (2007).

Généralement, la déformation d'une structure est réalisée par des actionneurs externes ou intégrés à la structure. Pour le M3C la structure entière est l'actionneur. Ainsi la déformation est obtenue en combinant les propriétés d'anisotropie thermoélastique d'une structure composite à une élévation de température. Afin de concevoir et optimiser un M3C, un modèle numérique simplifié est proposé. La corrélation avec des résultats théoriques et expérimentaux montre sa fiabilité et son utilité. La mise en place d'un protocole expérimental, permet de caractériser les performances de divers types d'échantillons M3C. De plus, des essais de vieillissement montrent la fiabilité de plaques tests en M3C. Une structure M3C est une structure active. En lui associant divers capteurs et un système de contrôle, celle-ci devient « intelligente ». Emin, deux applications industrielles possibles sont proposées : un système de fixation actif et la déformation du bord de fuite d'un profil de type NACA.

Full textAbstract:
To mitigate the effects of non-recurrent congestion on the United Kingdom motorway and trunk road network, the Highways Agency (HA) has developed the Incident Support Unit (ISU) service. This research presents a review of incident management practice in the United Kingdom, in particular on the M25 London Orbital Motorway. An international comparison between British incident management operations and those in the United States is also provided. The ISU service on the M25 motorway, operated by the HA’s service provider, Carillion plc, is critically examined, including quantitative and qualitative examinations and a benefit-cost estimation. To understand fully the influence that ISUs have on the M25 road network motorway, incident data was collected and analysed. These incidents have been examined to determine their influence on traffic flow. Specifically, their impact on the capacity of the roadway and the effect of “rubbernecking” is investigated. Investigations and analysis are undertaken to evaluate the delays experienced by motorway users due to incidents. The effectiveness of motorway matrix signals and signs are then examined including compliance rates with mandatory signals and the impact of variable message signs on driver route choice. Finally, the optimal standby locations of ISUs on the M25 sphere road network are established in order to reduce their response times to incidents.

Full textAbstract:
Globular cluster studies suggest that a signature in the spectra of RGB stars in a globular cluster are anti-correlations in Mg-Al and Na-O. In this work, a small sample of 12 RGB stars of the globular cluster M30 is investigated using VLT-UVES high-resolution spectrograph. I use photometric stellar parameters to derive the abundances of Fe, Na, Al and Mg in SIU – a visual spectral analysis tool using 1-dimensional hydrostatic plane parallel MAFAGS atmospheres assuming mixing length convection and treating line formation in LTE. We found signatures of Mg-Al anti-correlation in M30 with the majority of the stars belonging to the intermediate polluted group. Oxygen couldn’t be measured but an indirect clue to the Na-O anti-correlation is found due to the direct correlation of Al-Na. These results are consistent with recent studies of other globular clusters.

The distance scale in the universe is of key importance. To detennine the distance to objects far out in the universe, reliable distance indicators, or standard candles must be found and reliably characterised. This study focussed on the detection of cepheids and eclipsing binaries in the Andromeda Galaxy (M31) using the relatively new method of Difference Imaging Analysis (DIA), deemed to yield better results in crowded fields. Many eclipsing binaries and cepheids were found. Due the lack of spectroscopy, the calculation of distance using EBs was not possible, however accurate locations and periods for around 130 was secured for future work. The V-band Period luminosity relationship for M31 was calculated and found to agree with that of other authors, however poor determination of absolute photometry hampered efforts to perfonn investigations of other features ofthe relationship. The 1- band and Wesenheit W-band relationship were also detennined. The effects of blending on eclipsing binary and cepheid lightcurves was also Supplied by The British Library - 'The world's knowledge' investigated, and found to be significant is such a crowded field.

Full textAbstract:
FASTTRAC (Fast Adaptive Secondary for Tip-Tilt Removal by Automatic Centroiding) is a tip-tilt secondary system which increases the angular resolution of images taken at Steward Observatory's 90" Bok and 61" Bigelow telescopes. K band imagery is gathered with the facility infrared camera and wavefront sensing is done with a small format charge-coupled device (CCD). I examine desirable characteristics of wavefront-sensing CCDs and evaluate the performance of the device used in FASTTRAC according to those criteria. The main drawback of the device is its low quantum efficiency due to frontside illumination. The read noise of the system is adequate, particularly for FASTTRAC which is generally assigned to bright time. The increased angular resolution provided by FASTTRAC is desirable for imaging crowded fields, such as those found in Local Group galaxies. Stellar photometry is a more powerful tool for studying the structure of these galaxies than is surface photometry, in which the light from all types of stars is mixed together. In particular, the distribution of old stars is representative of the underlying mass distribution, so these stars may be used to measure the overdensity in the arms of spiral galaxies. FASTTRAC was used to observe fields in M33, the nearest spiral which is not seen edge-on. These fields were observed in a range of seeing conditions and with guide stars of varying magnitudes and positions relative to the fields of interest. I analyze the performance of FASTTRAC in these varying conditions and offer some advice to future FASTTRAC observers. I also analyze the crowding in the M33 fields and conclude that, to K∼16.5, it does not vary significantly with placement in or outside of a spiral arm. Therefore a coarsely-sampled, wide field survey of the populations of M33 will not be systematically biased by crowding. Therefore a survey covering 35' by 25' was conducted in I and K bands, covering all of M33 out to a deprojected radius of 16'. The resulting star catalogs reach a depth of about I=21.5 and Ks When plotted on a color-magnitude diagram, these stars separate into a young population of red supergiants and an older population of red giants. The giants are old enough to have experienced many orbits and are thus representative of the mass distribution of the galaxy. The fraction of K-band light which is "young" is only 5-10% indicating that surface photometry in general would not be terribly biased, but there are local variations in which the young component is much stronger. Fourier decomposition of the old catalog reveals significant amplitudes (up to 0.5), indicating that the galaxy does indeed contain local overdensities, which supports the basic idea of spiral density wave theory. The strongest component in M33 is one-armed or lopsidedness, with some power in the two-armed component and much less in the higher-order components. The two-armed component may in fact represent a bar in the inner few arcminutes.

Full textAbstract:
The M33 projectile has been analyzed using the ANSYS CFX code that is based on the numerical solution of the full Navier-Stokes equations. Simulation data were obtained against various Mach numbers ranging from M= 0.5 to M2.6 at 0 and 2 angles of attack. Simulation data were also obtained against various angles of attack from 0 to 85 for M= 0.5. For Mach numbers between M= 0.5 to 2.6, the results obtained using the combined k-epsilon and Shear Stress Transport model show good agreement with the experimental range data for the normal force and pitching moment coefficient. The drag coefficient at zero angle of attack tended to be over predicted by an average error of 11.6% with the highest error occurring at M= 1.5. For varying angle of attack up to 85 at M= 0.5, the results obtained from CFX code were compared with simulation results obtained from AP09. The data showed good agreement only up to 20 angles of attack.

Full textAbstract:
Con il termine Smart Grid si intende una rete urbana capillare che trasporta energia, informazione e controllo, composta da dispositivi e sistemi altamente distribuiti e cooperanti. Essa deve essere in grado di orchestrare in modo intelligente le azioni di tutti gli utenti e dispositivi connessi al fine di distribuire energia in modo sicuro, efficiente e sostenibile. Questo connubio fra ICT ed Energia viene comunemente identificato anche con il termine
Smart Metering, o Internet of Energy. La crescente domanda di energia e l’assoluta necessità di ridurre gli impatti ambientali (pacchetto clima energia 20-20-20 [9]), ha creato una convergenza di interessi scientifici, industriali e politici sul tema di come le tecnologie ICT possano abilitare un processo di trasformazione strutturale di ogni fase del ciclo energetico: dalla generazione fino
all’accumulo, al trasporto, alla distribuzione, alla vendita e, non ultimo, il consumo intelligente di energia.
Tutti i dispositivi connessi, diventeranno parte attiva di un ciclo di controllo esteso alle grandi centrali di generazione così come ai comportamenti dei singoli utenti, agli elettrodomestici di casa, alle auto elettriche e ai sistemi di micro-generazione diffusa. La Smart Grid dovrà quindi appoggiarsi su una rete capillare di comunicazione che fornisca non solo la connettività fra i dispositivi, ma anche l’abilitazione di nuovi servizi energetici a valore aggiunto.
In questo scenario, la strategia di comunicazione sviluppata per lo Smart Metering dell’energia elettrica, può essere estesa anche a tutte le applicazioni di telerilevamento e
gestione, come nuovi contatori dell’acqua e del gas intelligenti, gestione dei rifiuti, monitoraggio dell’inquinamento dell’aria, monitoraggio del rumore acustico stradale, controllo continuo del sistema di illuminazione pubblico, sistemi di gestione dei parcheggi
cittadini, monitoraggio del servizio di noleggio delle biciclette, ecc. Tutto ciò si prevede possa contribuire alla progettazione di un unico sistema connesso, dove differenti dispositivi eterogenei saranno collegati per mettere a disposizione un’adeguata struttura a basso costo e
bassa potenza, chiamata Metropolitan Mesh Machine Network (M3N) o ancora meglio Smart City.
Le Smart Cities dovranno a loro volta diventare reti attive, in grado di reagire agli eventi esterni e perseguire obiettivi di efficienza in modo autonomo e in tempo reale. Anche per esse è richiesta l’introduzione di smart meter, connessi ad una rete di comunicazione broadband e
in grado di gestire un flusso di monitoraggio e controllo bi-direzionale esteso a tutti gli apparati connessi alla rete elettrica (ma anche del gas, acqua, ecc).
La M3N, è un’estensione delle wireless mesh network (WMN). Esse rappresentano una tecnologia fortemente attesa che giocherà un ruolo molto importante nelle futura generazione
di reti wireless. Una WMN è una rete di telecomunicazione basata su nodi radio in cui ci sono minimo due percorsi che mettono in comunicazione due nodi. E’ un tipo di rete robusta e che offre ridondanza. Quando un nodo non è più attivo, tutti i rimanenti possono ancora comunicare tra di loro, direttamente o passando da uno o più nodi intermedi. Le WMN rappresentano una tipologia di rete fondamentale nel continuo sviluppo delle reti radio che denota la divergenza dalle tradizionali reti wireless basate su un sistema centralizzato come le reti cellulari e le WLAN (Wireless Local Area Network). Analogamente a quanto successo per le reti di telecomunicazione fisse, in cui si è passati,
dalla fine degli anni ’60 ai primi anni ’70, ad introdurre schemi di rete distribuite che si sono evolute e man mano preso campo come Internet, le M3N promettono di essere il futuro delle reti wireless “smart”. Il primo vantaggio che una WMN presenta è inerente alla tolleranza alla caduta di nodi della rete stessa. Diversamente da quanto accade per una rete cellulare, in cui la caduta di una Base Station significa la perdita di servizio per una vasta area geografica, le WMN sono provviste di un’alta tolleranza alle cadute, anche quando i nodi a cadere sono più di uno.
L'obbiettivo di questa tesi è quello di valutare le prestazioni, in termini di connettività e throughput, di una M3N al variare di alcuni parametri, quali l’architettura di rete, le tecnologie utilizzabili (quindi al variare della potenza, frequenza, Building Penetration Loss…ecc) e per diverse condizioni di connettività (cioè per diversi casi di propagazione e densità abitativa). Attraverso l’uso di Matlab, è stato quindi progettato e sviluppato un simulatore, che riproduce le caratteristiche di una generica M3N e funge da strumento di valutazione delle performance della stessa. Il lavoro è stato svolto presso i laboratori del DEIS di Villa Grifone in collaborazione con la FUB (Fondazione Ugo Bordoni).

Full textAbstract:
Cepheids have been used as distance indicators for almost a century. Through their well defined period-luminosity relation, their distance can be found from their period of pulsation alone. However, in recent years, an important uncertainty has arisen in its calibration, namely the effect of metallicity on the period-luminosity relation. It is important that we quantify this effect as Cepheids are used to tie down the base of the extragalactic distance scale. Without an accurate calibration for the nearest distances, the distances we measure for all other objects will be subject to systematic uncertainties. This thesis studies how the chemical composition of a Cepheid affects the zero-point of the period-luminosity relation, and quantifies the resulting change in measured distance modulus. The first study uses Cepheids in two areas of M33; a sample from the metal-rich central region is compared with the more metal-poor sample from the southern spiral arm. Period-luminosity relations in the reddening-free Wesenheit index Wvi are constructed for the two samples and the measured distance moduli are compared. A significant offset is found between the two samples. Effects such as reddening and blending are ruled out, leaving the change in metallicity as the only possible explanation for the discrepancy. The second study presented covers the whole of M33. Here, a sample of around 600 Cepheids is used, and the effect of metallicity on Wgi and Wri is measured. The same conclusion is found; the change in composition significantly affects the measured distance modulus of the Cepheid and the period-luminosity relation must be changed to take this into account. In addition, the Sloan band period-luminosity relations are derived empirically for the first time. The metallicity gradient of M33 is also assessed. It is found that the slope must be steep, at least in the central few kpc of the galaxy, but may flatten off at larger radial distances.

Full textAbstract:
The POINT-AGAPE collaboration, an international project looking for gravitational microlensing towards the Andromeda galaxy, uses the 'superpixel' technique to detect MAssive Compact Halo Objects (MACHOs). The 3-year survey has discovered about a dozen microlensing candidates. Part I of the thesis describes the project's background. Dark matter is discussed (cliapter 1). Microlensing is explained, emphasising the POINT-AGAPE work, and the superpixel technique is introduced (chapter 2). CCD technology and the Isaac Newton Telescope are discussed (chapter 3). In Part II the three recent POINT-AGAPE pipelines and their results are detailed, including the work at Queen Mary. The elimination of Mira variables is discussed, these masquerade as microlensing events (chapters 4 - 6). In addition we estimate the efficiency of detecting microlensing events (chapter 7). Part III describes various methodological issues associated with thesuperpixel technique, which uses a program called SExtractor to detect lightcurves with a bump. However, this generates fake lightcurves associated with CCD defects, bad pixels and resolved stars. Likelihood maps are investigated (chapter 8). The bad pixels and resolved stars were masked, but no mask is perfect and it is important to understand the degree of incompleteness. CCD defects are studied, their causes and effects are analysed; as are bright variable objects (chapter 9). In particular, a new method is described, involving close pairs of variables, which can be used in analysing the defects (chapter 10). Tight groups of variables are studied and bad columns analysed (chapter 11). Telescope pointing is investigated, relating offsets with defects and analysing anomalies in the bad columns. Field close pairs are discussed; once defective pairs are accounted for, what remains are genuine close pairs (chapter 12). Part IV discusses a search made for Cepheids (chapter 13) and summarises a coauthored paper on Nova discoveries in M31 (chapter 14). This is followed with appendicies with some more technical details. collaboration, an international project looking for gravitational microlensing towards the Andromeda galaxy, uses the 'superpixel' technique to detect MAssive Compact Halo Objects (MACHOs).

La pollution de l'air est un sujet de préoccupation majeur au XXIème siècle affectant la santé et notre environnement. Deux types de pollution atmosphérique retiennent plus particulièrement l'attention des physicochimistes à l'heure actuelle : la pollution à l'ozone dite photochimique et la pollution particulaire (PM10, PM2.5). La région Nord-Pas-De-Calais (NPDC) est une des régions françaises ayant la plus forte densité de population (324 hab./km2 en 2006). Elle est également le lieu de passage d'un trafic routier transfrontalier particulièrement intense. Enfin, elle présente une forte activité industrielle (pétrochimie, sidérurgie, métallurgie) au niveau de la zone côtière de Dunkerque. Les émissions issues des secteurs du transport mais aussi industriel et tertiaire sont une source importante de composés primaires (NOx, COV et particules) précurseurs de la pollution à l'ozone et particulaire.Au cours du travail de thèse les chaînes de modélisation MM5-CHIMERE et MM5-FLEXPART ont été installées et utilisées sur plusieurs périodes d'études à l'échelle de la région NPDC. Le système MM5-CHIMERE a été utilisé sur la période juin-juillet 2006 propice au développement d'épisodes de pollution photochimique. Diverses applications ont été réalisées : étude de la relation entre concentration en polluant et conditions météorologiques, impact de l'intégration du cadastre d'émission régional, impact de la résolution de la grille et des données dynamiques, origine locale/régionale des niveaux de pollution observés en région NPDC. Puis, le système MM5-FLEXPART a été utilisé afin de déterminer l'origine de deux évènements intenses de pollution particulaire observés en mars et décembre 2007 au niveau de Dunkerque. Enfin, les performances dynamiques et chimiques du système ont été évaluées au niveau de la zone spécifique industrielle de Dunkerque sur deux périodes en avril et mai 2006. Au cours de ces périodes, les données dynamiques ont été collectées lors d'une campagne de mesures réalisée sur Dunkerque par le Laboratoire de Physico-Chimie de l'Atmosphère (LPCA) de l'Université du Littoral - Côte d'Opale. Les résultats concernant la performance et les applications des systèmes ainsi que les perspectives à court terme seront présentés et discutés.

The performance of the MM5-CHIIMERE system has been evaluated for different topography and meteorological situations. Firstly, the modelled data are compared against observed data from the Atmo-NPDC air pollution monitoring network over the June-Ju!y 2006 heat wave period. Then, the dynamical and chemical performance of the models is assessed over the Dunkerque area for two periods in April and May 2006. For those two periods, measured data were collected during a field campaign achieved by the Laboratoire de Physicochimie Atmosphérique (LPCA) of the University du Littoral Côte d'Opale (ULCO). Finally, the MM5-FLEXPART system was used to determine the origin of an intense PM10 event over the NPDC region.
