While the world is urbanising at an exponential rate, so does the conflicts. The common environment for a conventional military force has changed from the open fields normally dominated by tanks and artillery, to narrow streets and buildings in a city. While the actors and environment for combat changes, the tactics doesn’t seem to. Maneuver warfare was mainly developed from the lessons learned from WW2 and was focused on warfare with large units using firepower and movement. But since the last two decades most of the fighting has taken part in urban areas against another type of enemy, which won’t allow for the full extent of the maneuvering and firepower due to structures and other obstructions in a city. This study will analyse how western militaries utilised the principles of maneuver warfare in urban combat. The goal is to measure how well the principles of maneuver warfare applicable in an urban environment against the ever-increasing irregular threat. The purpose is to indicate the complexity the urban environment brings to military units when planning and conducting operations. The results find that maneuver warfare relates well but can’t fully explain military success in urban warfare.

Le fond diffus infrarouge (CIB) provient de l'émission IR cumulée des galaxies sur toute l'histoire de l'Univers. Ainsi, le CIB sonde la formation et l'évolution des galaxies sur une grande gamme de décalage vers le rouge. Dans cette thèse, nous utilisons les anisotropies du CIB pour: i) Mesurer l'histoire de la formation des étoiles de l'Univers et le biais effectif des halos de matière noire hébergeant les galaxies CIB jusqu'à un décalage rouge élevé. En utilisant ces mesures, nous calculons la masse typique de ces halos de matière noire, sur une grande gamme de décalage vers le rouge. ii) En utilisant le CIB comme traceur de la structure à grande échelle, la corrélation croisée avec le CMB fournit une sonde alternative de l'énergie noire. Nous montrons que le CIB, extrait sur une grande fraction du ciel, peut fournir la meilleure mesure de l'effet ISW. En utilisant un formalisme matriciel de Fisher, nous prédisons l'amélioration des contraintes sur les paramètres cosmologiques en utilisant l'ISW mesuré avec le CIB. iii) Mesurer le spectre de puissance de l'effet Sunyaev-Zel'dovich cinétique (kSZ) caché dans les données du CMB. Nous améliorons les analyses existantes en combinant les mesures du CIB (de Planck/HFI et Herschel/SPIRE) et les observations de Planck, SPT et ACT pour étendre la gamme des échelles spatiales et des fréquences afin de faciliter la mesure du kSZ. Nous développons un nouveau modèle pour le CIB (pour pouvoir tenir compte des petites échelles spatiales), et modélisons de façon cohérente l'effet SZ thermique (tSZ) et la corrélation CIBxtSZ. Ceci est nécessaire pour séparer avec précision ces différentes composantes dans le spectre de puissanceThe CIB is the cumulative infrared emission from all the galaxies throughout cosmic history. Its distinct frequency-redshift dependence allows to probe a large span of redshifts. In this thesis, we utilise the CIB anisotropies detected by the Planck satellite to:i) Measure the star formation history of the Universe and the effective bias of the dark matter halos hosting the CIB galaxies to a high redshift. Using these measurements, we calculate the typical mass of the host dark matter halos for the CIB galaxies at different times.ii) Using the CIB as a tracer of the large scale structure, the cross-correlation with the CMB provides with an alternative probe of the dark energy. We showed that the CIB, extracted on a large fraction of the sky, may provide the best Integrated Sachs Wolf measurement (in terms of S/N ratio). Using a Fisher matrix formalism, we also predict the improvement on the constraints on the cosmological parameters using the ISW measured with this technique. We cross-correlate the best available maps of the CIB and the CMB and find that the dust residuals in the CIB maps are too high to detect the ISW through this method.iii) Measure the kinetic Sunyaev-Zel'dovich (kSZ) power spectrum hidden in the CMB power spectrum. We improve upon the existing analysis by combining the CIB measurements (from Planck/HFI and Herschel/SPIRE) and multi-frequency observations by Planck, SPT and ACT to extend the range of scales and frequencies to facilitate the kSZ measurement. We develop a power spectrum analysis based on physically motivated but simplistic and consistent models of foreground components (CIB, tSZ, tSZxCIB) to accurately separate the kSZ from the CMB

Full textAbstract:
The complement 3b/4b receptor 1 (CR1) gene is located at chromosome 1q32.2 in a cluster of complement-related genes. CR1 regulates both classical and alternative pathways of the complement system. CR1 is a major receptor for Plasmodium falciparum, and variation within the gene has been associated with different malarial clinical phenotypes. CR1 shows intragenic copy number variation (CNV) resulting in variation in protein length and number of C3b/C4b binding domains. Previously, CR1 was related to Alzheimer’s disease (AD) via complement system regulation. Furthermore, CR1 variation is responsible for the alleles of the Knops blood group, including McCoy and Swain-Langley. In this thesis, Novel paralogue ratio test (PRT) assays were developed to robustly type CNV of the low-copy repeat (LCR) regions (which defines the common CR1-A and CR1-B alleles, but also rarer alleles) within the gene in large cohorts, and an allele-specific hybridisation assay to genotype alleles of the Knops blood group system. Variation was analysed across global populations, and in the Tori-Bossito cohort (563 infants) from Benin, followed since birth to observe malaria acquisition and treatment. This showed that the Swain-Langley Sl2 polymorphism is not in strong linkage disequilibrium (LD) with the CNV, nor with other Knops blood group alleles. It appears to provide protection against early acquisition of malaria and subsequent number of malarial infections in the Tori-Bossito cohort but these results were not confirmed in an independent cohort (n=276). The association between the CR1-B allele and AD (early-onset (EOAD) and late-onset (LOAD)) was explored, showing that the CR1 risk loci (rs3818361, rs6656401 (only for EOAD) and rs6701713) were in moderate LD with CR1-B, but revealing no association between CR1-B (p=0.755) and EOAD (n=633). However, the CR1-B allele (risk) appears to be associated with LOAD (n=2185) with (p=0.015) and without (p=0.048) use of a junction fragment PCR assay.

Full textAbstract:
CR1 (CD35, récepteur pour le C3b/C4b) est une glycoprotéine transmembranaire présente sur de nombreux types cellulaires. Son rôle principal à la surface des érythrocytes (E) est le transport des complexes immuns vers le foie et la rate où ils sont éliminés. Nous avons montré que le Macaque rhésus (Macaca mulatta, MM) exprime un CR1 équivalent à celui de l’Homme en taille, en densité et réparti en bouquets. Ce CR1 présente des polymorphismes allotypiques. Il exprime aussi un CR1 plus court (CR1like, CR1L), plus abondant, plus diffus, à ancrage glycophosphatidylinositol. Nous avons décrit des polymorphismes de la région Sla de CR1 impliquée dans les phénomènes d'adhérence inter-érythrocytaire entre les E parasités par P. Falciparum et les E sains chez 12 espèces de primates. Ils ne protègent pas les E de MM contre la formation des rosettes avec des E humains parasités. Nous avons séquencé les promoteurs de CR1 et CR1L de MM (MCR1, MCR1L). AML1 activateur de CR1 humain est présent dans MCR1 mais absent de MCR1L. Ets et MZF1 sont conservés. Nous avons identifié un polymorphisme allèlique (délétion de 18 nucléotides) dans CR1L humain. Nous avons étudié le dépôt de C4d érythrocytaire (EC4d) de transplantés rénaux concomitamment à l'analyse de la biopsie du greffon. Il existe une relation entre le EC4d et le marquage diffus C4d des capillaires péritubulaires du greffon ; et entre le EC4d et les lésions histologiques retrouvées en situation de rejet aigu humoral. Le EC4d offre un intérêt pour le diagnostic et le suivi des rejets en transplantation rénale. Le mécanisme des dépôts de C4d reste à élucider. L’activation de la voie classique du complément ne semble pas impliqué@CR1 (CD35, the C3b/C4b receptor) is a transmembrane glycoprotein found on few cell types. Erythrocyte CR1 (E-CR1) is involved in immune complex (IC) clearance in liver and spleen. The binding of IC on E is improved by cluster distribution of CR1 enabling a strong avidity multivalent binding. Rhesus macaque (Macaca mulatta) was shown to express a transmembrane E-CR1 as observed in Human (same length, density, cluster distribution). This “human-type” CR1 was characterized by allotypic polymorphisms. A shorter CR1 was also observed, called CR1like (CR1L) which was more abundant, more diffuse and glycophosphatidylinositol anchored. Polymorphisms of CR1 Sla region involved in rosetting between healthy E and P. Falciparum infected E were described in 12 primate species. E from rhesus macaque were not prevented from rosetting with human infected E by those polymorphisms. CR1 and CR1L promoters from rhesus macaque (MCR1, MCR1L) were sequenced. AML1 known as human CR1 activator was found in MCR1 but was missing in MCR1L. Ets and MZF1 were conserved. HES1 et LBP1 might downregulate MCR1 and human CR1L. An allelic polymorphism corresponding to a 18 nucleotide deletion was observed in human CR1L promoter. C4d deposition at E surface (EC4d) of patients suffering from kidney acute humoral rejection was compared with biopsy analysis and related to C4d tissue deposits. EC4d appears a promising non-invasive marker of acute humoral rejection. The mechanism of C4d deposition remains to be investigated. Complement classical pathway activation did not seem to be involved

Full textAbstract:
Questa tesi mira a valutare la sostenibilità ambientale ed economica di una scuola di tre classi, costruita in mattoni di terra cruda compressa a Dougourakoro, in Mali, seguendo i principi della progettazione bioclimatica. A questo scopo, è stata condotto uno studio LCA che compara due diversi casi di studio: l’edificio bioclimatico in mattoni compressi di terra cruda ed un edificio in mattoni forati di cemento, che rispecchia la tipologia costruttiva maggiormente diffusa localmente. L’utilizzo della terra cruda come materiale da costruzione, infatti, è stato localmente soppiantato negli ultimi decenni da mattoni in cemento che necessitano di una minore manutenzione.
I risultati dell’analisi LCA indicano un minore impatto ambientale dell’edificio in terra cruda, che si crede possa essere ulteriormente accentuato da una futura inclusione nell’analisi della fase di uso. I maggiori costi che è necessario sostenere durante la costruzione corrispondono ad una maggiore quantità dei materiali utilizzati e ad una superiore complessità delle lavorazioni durante la costruzione. Sintetizzando i risultati, si conclude che, nonostante l’edificio in terra cruda abbia un minore impatto ambientale, il potenziale inespresso di questo materiale è ancora altissimo, potendo manifestarsi appieno, però, solo dopo una rinnovata accettazione sociale, stimolata attraverso attività formative in loco che potrebbero portare ad una maggiore diffusione di conoscenze, conoscenze e macchinari legati a questo materiale, abbattendone così, i costi di produzione e costruzione.

Full textAbstract:
L'Univers, en dehors de notre Galaxie, est baigné de nombreux rayonnements, le principal étant observable dans le domaine des ondes radio centimétriques et millimétriques: le fond cosmologique (ou CMB pour {\it Cosmic Microwave Background}), corps noir de température actuelle 2.7 Kelvin. Découvert dans les années soixante, et largement étudié depuis pour ses infimes fluctuations de température et de polarisation, il se propage librement depuis une époque située environ 400000 ans après le big-bang. Il nous renseigne sur l'état de l'Univers primordial, sur son contenu, ainsi que sur certains processus physiques ayant eu lieu ultérieurement, comme la réionisation ou la formation des amas de galaxie. Un autre rayonnement d'importance cosmologique a été découvert il y a seulement quatorze ans dans les données du satellite COBE, mais ici dans le domaine de l'infrarouge lointain, vers 200 microns de longueur d'onde: le {\bf rayonnement fossile des galaxies}, ou fond diffus extragalactique infrarouge. Il est environ 50 fois moins intense que le fond cosmologique (pic à pic, ou de 20 à 40 fois moins en intégrale). Cette détection a constitué une grande surprise vu la grande intensité relative de l'infrarouge lointain par rapport à la partie visible provenant directement des étoiles. Ce fond diffus a pour origine l'émission de toutes les galaxies depuis leur formation, et résume ainsi toute leur histoire. Il est donc permis d'écrire, presque sans ironie, que {\bf la nuit n'est pas noire}, dans la mesure où, si nos yeux (avec le concours d'une hypothétique fenêtre atmosphérique) étaient sensibles aux rayonnements infrarouge lointain, millimétrique et centimétrique, ils verraient une nuit brillante de rayonnements cosmologiques. Notons que la question de la nuit noire - connue sous le nom de paradoxe d'Olbers Chéseaux - est ancienne, fertile, et touche aux fondements de la description et la compréhension de notre Univers physique, de son origine et de son évolution. Mesurer précisément ce rayonnement de fond infrarouge et comprendre la nature des galaxies qui en sont à l'origine et leur évolution, constituent l'une des thématiques importantes de la cosmologie observationnelle d'aujourd'hui. Je détaille, dans ce manuscrit de HDR, quelques-unes de mes contributions à l'étude statistique des galaxies infrarouges, à la mesure et l'interprétation du rayonnement extragalactique, et esquisse quelques perspectives.

AdVantage in Cab, es un proyecto innovador que busca hacer converger tanto la evolución tecnológica en la que se encuentra la sociedad actualmente y las necesidades de 2 actores claves para el desarrollo adecuado del proyecto. Posesionados desde la demanda, se detecta la necesidad de modernización y asesoría tecnológica de los gremios de taxis convencionales incluyendo en su oferta soluciones tecnológicas como la propuesta. Por otra parte, y para poder financiar la propuesta, se detecta la necesidad creciente de las agencias publicitarias de poder segmentar cada vez con mayor exactitud, las exposiciones de sus campañas. Dado lo anterior, AdVantage in Cab ofrece una plataforma para difusión publicitaria al interior de los taxis convencionales, a través de Tablet instaladas en la parte posterior del asiento del copiloto, la cual proyecta campañas dependiendo del sector y el pasajero que contrata el servicio de transporte. Dicha Tablet es capaz de realizar una estimación de sexo y rango etario del pasajero con la finalidad de segmentar posteriormente la publicidad emitida y direccionar lo que las agencias necesiten. El análisis de la industria entrega resultados favorables, lo que, complementado con el aumento en la inversión en publicidad digital en Chile, que en la última década pasó de 1,4 a 14,7% del total invertido, aumenta las posibilidades de éxito. En cuanto al análisis financiero se aprecia un horizonte de maduración del negocio de 5 años, logrando al año 3 un VAN estimado de $11 MM.

Full textAbstract:
At UDBL (Uppsala DataBase Laboratory) we are developing the DSMS SCSQ (SuperComputer Stream Query processor) based on the main memory DBMS Amos II. Amos II is a functional DBMS where data and information are represented as typed functions. In SCSQ database queries over streams are expressed in the functional query language SCSQL, a language similar to the object oriented parts of SQL:99 but extended with parallel stream query facilities. In this paper we investigate what existing functionality in SCSQ and Amos II can be utilized to support CQL, a continuous query language developed by the Stanford STREAM project. SCSQL is extended with functionality required to support CQL. The extended functional stream query language is called FCQL. To implement FCQL, SCSQ is extended with new operators that adhere to the semantics of CQL. FCQL is a functional continuous query language with the same expressive power as CQL. Furthermore, we show how CQL queries can be translated to FCQL in a systematic way and by doing so give a template for an automatic CQL-to-FCQL translator. We also evaluate the completeness of FCQL by translating to FCQL the queries of the linear road DSMS benchmark as it was expressed in CQL by the Stanford STREAM project.

Full textAbstract:
The forest industry plays an important role in Sweden, and forest machine manufactures are underconstant pressure to achieve both high productivity and comfortable operating environment in its products. A forwarder is a forestry vehicle that carries logs which are cut by a harvester. It suffers alot of low frequency and high amplitude vibrations during the operation because of the rough terrainin forests. Therefore, it is necessary and vital to introduce an active cab suspension system in orderto reduce the whole vibrations in the forwarder cab.The main purposes of this thesis are to develop, implement and test a feasible control strategy forthe active cab suspension system as well as verify the controller’s performance in terms of vibrationreduction and power consumption. This project is focused on the available mechanical rig installedat KTH lab hall, instead of a real forwarder.A deep study has been carried out on a new valve prototype. Exhausted tests were made to testthe performance of this valve under different conditions. From the test results, the valve was tunedin order to get the best performance out of it. Once the valve has been well calibrated, a model ofthe whole system was estimated by using Black-box estimation. The model has a 96% of matchingbetween the stimulation data and the validation data. Different controllers were designed with thismodel, and the best one was designed by the gain scheduling method.The system has a delay of 36 ms, therefore, it was studied how the performance of this controllerwould increase if this delay was reduced. The study shows that reducing the delay to around 0-2ms, the suspension system is able to reduce the vibration from 60% to 90%. Smith Predictor wasimplemented into the gain scheduling controller in order to reduce the effect of the delay. The resultsdemonstrated a better and more robust performance of the controller with Smith Predictor.Several test cases were implemented to seek a wide range of possible vibrations that a forwardercould handle in the forest. These tests have been done both in a test rig and in a simulationenvironment. The final test was conducted by using a real track test model obtained from Skogforsk.This track is used for testing different systems in a test forwarder since it simulates the terrain ina forest. Based on the simulation result, the total disturbance reduction percentages of SmithPredictor controller are 75% for heave, 68% for pitch and 73% for roll, which shows the systemreduces the cab vibration. Moreover, the maximum amount of power needed during the forwarderoperation is 11.63 kW which is feasible for implementing this system on the actual forwarder.

This thesis presents the measurement of the cosmic microwave background (CMB) power spectrum for the Atacama Cosmology Telescope (ACT) experiment and its polarized upgrade, ACTPol. I present the tools that I have developed for constructing unbiased and nearly optimal statistical estimators. I discuss how to separate the cosmological and the astrophysical signal and how to characterize instrumental systematics. The goal of this work is to obtain accurate power spectra measurement that can be used for cosmological parameter estimation. I first present the analysis of the complete ACT data set. The high resolution of the telescope allows us to recover power spectra to ℓ = 10000. I report the measurement of the power spectra at 148 GHz and 218 GHz, as well as the cross-frequency spectrum between the two channels. The power spectrum measurement is consistent with the ΛCDM model and a basic foreground model. I then present the cross correlation of maps from the Atacama Cosmology Telescope with maps from the Planck satellite in two overlapping regions covering 592 square degrees. I find excel- lent agreement between the two datasets at both frequencies, quantified using the variance of the residuals between the ACT power spectra and the ACT×Planck cross-spectra. The next generation of CMB experiments are focused on measuring its polarization. I present efficient algorithms for CMB lensing simulation and power spectrum estimation for flat-sky CMB polarization maps. Finally, I discuss the first temperature and polarization power spectra measurement from the ACTPol experiment. They are the first attempt to measure the polarization of the CMB at high resolution.

Full textAbstract:
La Radiazione Cosmica di Fondo (CMB) è la radiazione emessa nell’Universo primordiale dopo la ricombinazione di elettroni e protoni in idrogeno neutro. Le osservazioni della CMB negli ultimi 30 anni hanno fortemente contribuito alla nascita della cosmologia di precisione, e all’affermazione di un modello cosmologico standard, denonimato ΛCDM, i cui parametri sono stimati con un’incertezza dell’ordine del percento o addirittura inferiore. Ciò nonostante ci sono caratteristiche non ben comprese osservate alle grandi scali angolari della mappa in temperatura di CMB, note come anomalie. Una di queste, la mancanza di potenza rispetto a quanto previsto nel modello ΛCDM, potrebbe indicare l’esistenza di una nuova fase cosmologica antecedente all’epoca inflazionaria. Tale anomalia, osservata in modo consistente sia da WMAP che da Planck, non possiede però la significatività statistica necessaria per affermare l’esistenza di tale nuova fase. Al fine di studiare questa mancanza di potenza abbiamo utilizzato diversi estimatori statistici, che includono nell’analisi sia le mappe in temperatura che quelle in polarizzazione. Estimatori specifici ed innovativi, basati sullo spettro di potenza angolare della CMB, sono stati costruiti, testati e utilizzati su simulazioni e sui dati ottenuti dal satellite Planck nel 2015. Il confronto tra le simulazioni e i dati è stato valutato fornendo la percentuale di consistenza. Sono state inoltre fornite previsioni sulla sensibilità degli estimatori proposti quando impiegati su future osservazioni di CMB. Il miglioramento trovato può arrivare a un fattore dell’ordine 30, dimostrando che le misure future di polarizzazione della CMB potranno aiutare a trasformare una anomalia, attualmente osservata solo in temperatura, in una rilevazione di un nuovo fenomeno fisico.

According to the WMAP and earlier COBE observations, the Cosmic Microwave Background (CMB) anisotropy power on large angular scales appears to be significantly lower than predicted by the standard model of cosmology. We propose a scalar field model of the dark energy as a mechanism for suppressing low l multipoles through late-Universe evolution of metric fluctuations and the integrated Sachs-Wolfe (ISW) effect. We find that for a constant dark energy equation of state, theoretical predictions actually give a larger (instead of a desired smaller) value of the quadrupole and other low l multipoles.

Full textAbstract:
The primary argument in favor of mass customization is the delivery of superior customer
value. Using willingness-to-pay (WTP) measurements, Franke & Piller (2004) have recently
shown that customers designing their own watches with design toolkits are willing to pay
premiums of more than 100% (DWTP). In the course of three studies, we found that this type
of value increment is not a singular occurrence but might rather be a general phenomenon, as
we again found average DWTPs of more than 100% among customers designing their own
cell phone covers, T-shirts, and scarves. Building on this, we discuss the sources of benefits
that are likely to explain this tremendous value increment. We argue that compared to
conventional standard products, a mass-customized product might render the following
utilitarian and hedonic benefits: (1) First, the output might be beneficial as self-designed
products offer a much closer fit between individual needs and product characteristics. In
addition to this mere functional benefit, extra value might also stem from (2) the perceived
uniqueness of the self-designed product. As the customer takes on the role of an active codesigner,
there may also be two general 'do-it-yourself effects': (3) First, the process of
designing per se is likely to allow the customer to meet hedonic or experiential needs (process
benefit). (4) Customers may also be likely to value the output of self-design more highly if
they take pride in having created something on their own (instead of traditionally buying
something created by somebody else). This is referred to as the 'pride of authorship' effect. (author's abstract)

Full textAbstract:
What type of reward attracts customers to loyalty programs? Given the increasing importance of loyalty programs, this question matters. Six sequential studies investigated whether monetary rewards universally attract people more than nonmonetary rewards. Results suggest that monetary rewards elicit a very robust attractiveness premium both on the level of individual rewards as well as on the level of entire reward programs. Across different industries, the more monetary loyalty program was consistently perceived as more attractive, and it was more likely to inspire intentions to join the program. Even in light of variations in consumption goals (hedonic vs. utilitarian), the effect persisted. The effect is not only consistent; it is also nonnegligible with medium effect sizes emerging in most settings. We discuss ensuing variations in effect sizes and conclude that monetarism holds a pervasive temptation for consumers that managers cannot ignore.

Full textAbstract:
La prochaine génération de mesures du fond diffus cosmologique (CMB) continuera d’établir le domaine de la cosmologie comme une science de haute précision et ne cessera d’ouvrir de nouvelles frontières en physique fondamentale. Les mesures limitées par la variance cosmique de la température du CMB, mais aussi de sa polarisation jusqu'aux minutes d'arc, permettent des mesures précises de notre modèle cosmologique, qui est sensible à la physique insaisissable de la matière noire, de l'énergie noire et des neutrinos. De plus, une mesure aux grandes échelles de la polarisation CMB, dite “mode B”, permettra de déterminer la puissance des ondes gravitationnelles primordiales, générées par des phénomènes potentiellement présents dans le tout jeune univers, à des échelles d’énergie qui s’approchent de la théorie de grande unification. L'entrée dans un nouveau régime de sensibilité implique la nécessité d'améliorer notre compréhension de la physique et des méthodes d'analyse des effets systématiques astronomiques et instrumentaux.Dans ce contexte, cette thèse présente plusieurs analyses des possibles effets systématiques astronomiques et instrumentaux, principalement centrés sur les mesures CMB dans le cadre du lentillage gravitationnelle faible. Cet effet déforme le trajet des photons primaires du CMB, de sorte que les propriétés statistiques du signal mesuré s'écartent du signal primaire, et il faut donc prendre en compte cette distorsion. Cette thèse décrit la physique fondamentale, les méthodes d'analyse et les applications aux ensembles de données actuels de POLARBEAR, une expérience CMB dans le contexte scientifique des lentilles gravitationnelles.En particulier, cette thèse établit que les futures mesures de haute précision des lentilles gravitationnelles devront prendre en compte la haute complexité de cet effet, principalement causée par des déflexions multiples, induites par une distribution non linéaire des structures à grande échelle en évolution. De plus, l’impact des corrélations d’ordre supérieur, introduites par les avant-plans galactiques et par l’analyse jointe de données aux petites et aux grandes échelles, est étudié. Cette thèse démontre la nécessité d’observations des petites échelles dans plusieurs bandes de fréquences, ainsi que l’utilisation de techniques pour supprimer les avant-plans, afin d’obtenir une estimation sans biais du rapport tenseur-sur-scalaireNext-generation cosmic microwave background (CMB) measurements will further establish the field of cosmology as a high-precision science and continue opening new frontiers of fundamental physics. Cosmic-variance limited measurements not only of the CMB temperature but also its polarization down to arcminute scales will allow for precise measurements of our cosmological model, which is sensitive to the elusive physics of dark matter, dark energy and neutrinos. Furthermore, a large-scale measurement of B-mode CMB polarization permits a determination of the power of primordial gravitational waves, generated by processes potentially happening in the very early universe at energies close to the scale of the Grand Unified Theory. Entering a new sensitivity regime entails the necessity to improve our physical understanding and analysis methods of astronomical and instrumental systematics.This thesis presents within this context several analyses of potential astronomical and instrumental systematics, primarily focusing on CMB measurements related to weak gravitational lensing. The latter distorts the path of the primary CMB's photons, such that the statistical properties of the measured signal deviate from the primary signal and, hence, has to be accounted for. This thesis describes the underlying physics, analysis methods and applications to current data sets of the POLARBEAR CMB experiment in the context of CMB lensing science.This thesis shows that future high-precision measurements of CMB lensing have to account for the high complexity of this effect, primarily caused by multiple deflections within an evolving, non-linear large-scale structure distribution. Furthermore, the impact of higher-order correlations introduced by galactic foregrounds and CMB lensing when jointly analyzing CMB data sets on both large and small scales is investigated, showing the need for small-scale multi-frequency observations and foreground removal techniques to obtain an unbiased estimate of the tensor-to-scalar ratio

Full textAbstract:
QUaD is a ground based bolometric polarimeter which observed the cosmic microwave background (CMB) at 100 and 150 GHz for three austral winters. Two different techniques field differencing and ground template subtraction, were used to analyze the data providing highly accurate maps and power spectra of both temperature and polarization. These measurements were then used to constrain cosmological parameters and in conjunction with the results of several other experiments further our knowledge and understanding of cosmology in the early universe. This thesis presents an investigation into the astrophysical phenomena in the fore ground of QUaD's observation region. Although an area with minimal foreground was selected for the experiment, nevertheless between QUaD and the CMB there are various sources of millimeter radiation that could potentially contaminate the measurements. Template temperature maps of the dust and synchrotron radiation in the region are extrapolated to CMB frequencies and correlated with QUaD's maps to quantify the extent of any structure similarity detected. These are compared with the correlation expected by chance in a single universe to confirm the cleanliness of the field and highlight the robustness of the published CMB results. The residual signal persistently observed in the difference spectrum between QUaD's 100 GHz and 150 GHz frequency data is fitted against template spectra for the far infrared background (FIRB) and the Sunyaev-Zel'dovich (SZ) effect. The fitting analysis serves to constrain the parameters, b (the galaxy clustering bias), and a8 (the rms mass fluctuations in a Sh l Mpc sphere) upon which the amplitudes of the template spectra are dependent. The contribution to the power from the predicted background of radio point sources is subtracted before a simultaneous fit to the two parameters is carried out. It is found that cr8 = l.lllo!o6 = 3-2T to 23. Whilst these values are shown to be consistent with other recent astronomical results, the amplitudes of the FIRB and SZ effect they imply are, once extrapolated to high-, incompatible with the QUaD data on these angular scales. This suggests that some other factors perhaps instrumental systematics, features in the analysis pipeline, or indeed other astrophysical phenomena could also be responsible for the signal seen in the frequency difference spectrum.

Full textAbstract:
With changing market demands such as individualization, volatility and sustainability, the current manufacturing environment at Scania is subject to an increasing need for change. This, together with the availability of more advanced technology and digitalization has sparked the fourth industrial revolution. It has been named Industry 4.0 and considers digitalization in a manufacturing environment. As a result, the purpose of this thesis is to outline the potential of increased digitalization for logistics and manufacturing at Scania Oskarshamn. This will be done by developing a digitalization strategy that encapsulates the core of Industry 4.0 and a roadmap to guide Scania in their development towards a future digitalized manufacturing environment. The study will consider two core functions of Industry 4.0 as the cornerstones of digitalization; consciousness and interoperability. Consciousness focuses on the level of digitalization within the system. With interoperability, integration throughout the whole supply chain and how it relates to the manufacturing environment. As a result, the study is separated into three main parts: Scania today, Scania 2030 and the gap in-between. For all three parts, three areas of focus will be the basis for the analysis. First, the level of digitalization will be analyzed. This is done in regards to the first core function, consciousness. Second, the level of process maturity will be analyzed. This is done in regards to the second core function, interoperability. Third, synergies between logistics and manufacturing will be analyzed. From the conducted analysis of the current state at Scania, the 2030 scenario and the gap inbetween, the digitalization strategy for Scania focuses on the two identified functions. Three key steps has been developed for each function.

Full textAbstract:
The goal of this project is to gain a better understanding of the temperature fluctuations observed in the CMB. This goal is reached with the aid of a literature study. The report touches upon the origin of the CMB as well as how it is measured, mentioning and explaining relevant concepts such as recombination, photon decoupling, black body radiation, angular power spectrum etc. It is also specified that the temperature of the CMB is not uniform but varies slightly. The fact that these fluctuations show inhomogeneities at the early universe is emphasized as well as the need for a satisfying theory that explains said fluctuations. By presenting and employing inflation theory in combination with quantum mechanics, we show how such a theory can be obtained. Through extensive calculation we show how the primordial power spectrum for zero-point fluctuations during inflation is obtained and how it can be related to the time of recombination through a transfer function, thus explaining the existence of fluctuations in the CMB.Målet med detta projekt är att få en bättre förståelse om observerade temperaturfluktuationer i CMB. Detta mål är uppnått med hjälp av en litteraturstudie. Rapporten nämner uppkomsten av CMB samt hur den mäts, nämner och förklarar relevanta koncept som rekombination, foton frikoppling, svartkroppstrålning, vinkelkraftspektrum etc. Det är också specificerat att temperaturen av CMB inte är enhetlig utan varierar en aning. Faktumet att dessa fluktuationer visar på inhomogeniteter i det tidiga universum är betonat samt behovet av en tillfredställande teori som förklarar dessa fluktuationer. Genom att presentera och använda inflationsteori i kombination med kvantmekanik visar vi hur en sådan teori kan erhållas. Genom omfattande beräkningar visar vi hur det ursprungliga kraftspektrumet för nollpunktsfluktuationer under inflation är erhållet och hur det kan relateras till tiden för rekombination genom en överföringsfunktion, som således förklarar existensen av fluktuationer i CMB.

Full textAbstract:
The skyrocketing costs of prescription medicine in developed countries and their lack of availability in developing countries are the most challenging problems of human health. Primary reasons for such high cost are fermentation-based production, expensive purification methods, the need for low temperature storage and transportation and the delivery through sterile injections. Most of these expenses could be minimized or eliminated when therapeutic proteins are expressed and orally delivered via plant cells. Chloroplasts have the machinery to fold complex and biologically active eukaryotic proteins in the soluble chloroplast stromal compartment. Protein expression through chloroplast transformation system offers a number of advantages over nuclear transformation such as a high level of transgene expression (up to 47% of the total soluble protein), due to the presence of 10,000 copies of the transgene per cell, which is uniquely advantageous for oral delivery of adequate amounts of the therapeutic protein or vaccine antigen. It is also an environmentally friendly approach due to effective gene containment and lack of transgene expression in pollen since the chloroplast genome is maternally inherited. To study receptor-mediated oral delivery of therapeutic proteins using the transmucosal carrier cholera toxin B subunit (CTB), a CTB-GFP fusion protein separated by a furin cleavage site was expressed via the tobacco chloroplast genome and used as a visible marker. Site specific integration of the transgene was confirmed by PCR analysis. Southern blot analysis confirmed homoplasmy. Immunoblot analysis confirmed the expression of both the monomeric as well as the pentameric forms of CTB-GFP in transgenic plants. Expression levels of upto 21.3% were obtained and the functionality of the CTB-GFP pentamers was confirmed by an in vitro GM1 binding assay. GFP was seen in the intestinal mucosa, liver and spleen of mice orally fed with CTB-GFP expressing leaves, while CTB was detected only in the intestinal cells. Intestinal macrophages and dendritic cells stained positive for both the CTB as well as GFP. These results suggest successful cleavage of the foreign protein from the transmucosal carrier and its delivery to various organs. These investigations should facilitate the development of a novel cost-effective oral delivery system for plant-derived therapeutic proteins.M.S.

Reactive oxygen species (ROS) are continuously generated and can be derived from cellular metabolism or induced by exogenous factors, in addition, have the capacity to damage molecules like DNA and proteins. BER is considered the main route of DNA damage oxidative repair, however, several studies have demonstrated the importance of the proteins participation of other ways to correct these injuries. NER enzymes deficiency, such as CSB and XPC, acting in the damage recognition step in the two subways this system influences the effectiveness of oxidative damage repair. However, the mechanisms by which cells deficient in these enzymes respond to oxidative stress and its consequences still need to be better understood. Thus, the aim of this study was to perform a proteomic analysis of cell lines proficient and deficient in NER, exposed to oxidative stress, in order to identify proteins involved, directly or not, in response to oxidative stress and DNA repair. For this, three strains of human fibroblasts, MRC5-SV, CS1AN (CSBdeficient) and XP4PA (XPC-deficient) were treated with photosensitized riboflavin and then carried out the differentially expressed proteins identification by mass spectrometry. From the results, it was observed in MRC5-SV increase expression in most of the proteins involved in cellular defense, an expected response to a normal cell line subjected to stress. CS1AN showed a response disjointed, it is not possible to establish many interactions between the proteins identified, may be one explanation for their sensitivity to treatment with riboflavin and other oxidants and increased cell death probably by induction of pro-apoptotic pathways. Already XP4PA showed higher expression of apoptosis-blocking proteins, as there was inhibition or reduced expression of others involved with the activation of this process, suggesting the activation of an anti-apoptotic mechanism in this lineage, which may help explain the high susceptibility to develop cancers in XPC individuals. These results also contribute to elucidate action mechanisms of NER in oxidative damage and the understanding of important routes in the oxidative stress correlation, repair and malignant tumors formation
Esp?cies reativas de oxig?nio (EROs) s?o geradas, continuamente, podendo ser provenientes do metabolismo celular ou induzidas por fatores ex?genos, al?m disso, apresentam a capacidade de danificar mol?culas, como DNA e prote?nas. BER ? considerada a principal via de reparo de danos oxidativos ao DNA, entretanto, diversos estudos tem demonstrado a import?ncia da participa??o de prote?nas de outras vias na corre??o destas les?es. A defici?ncia de algumas enzimas da via NER, como CSB e XPC, que atuam na etapa de reconhecimento da les?o nas duas subvias deste sistema, influencia na efic?cia do reparo de danos oxidativos. Entretanto, os mecanismos atrav?s dos quais, c?lulas deficientes nestas enzimas respondem ao estresse oxidativo e suas conseq??ncias ainda necessitam ser mais bem esclarecidos. Desta forma, o objetivo deste trabalho foi realizar uma an?lise prote?mica de linhagens celulares proficiente e deficiente em NER, expostas ao estresse oxidativo, de modo a identificar prote?nas envolvidas, diretamente ou n?o, na resposta ao estresse oxidativo e reparo de DNA. Para isto, tr?s linhagens de fibroblastos humanos, MRC5-SV, CS1AN (deficiente em CSB) e XP4PA (deficiente em XPC), foram tratadas com riboflavina fotosenssibilizada e, em seguida, foi realizada a identifica??o das prote?nas diferencialmente expressas atrav?s do seq?enciamento de pept?deos por espectrometria de massas. A partir dos resultados, observou-se que a linhagem MRC5-SV apresenta aumento de express?o na maioria das prote?nas envolvidas com a defesa celular, sendo uma resposta esperada para uma linhagem celular normal submetida a estresse. A linhagem CS1AN demonstrou uma resposta desarticulada, n?o sendo poss?vel estabelecer muitas intera??es entre as prote?nas identificadas, podendo ser uma explica??o para sua sensibilidade a tratamentos com riboflavina e outros agentes oxidantes e aumento da morte celular provavelmente por indu??o das vias pr?apopt?ticas. J? linhagem XP4PA apresentou maior express?o de prote?nas bloqueadoras da apoptose, assim como, houve a inibi??o ou redu??o da express?o de outras envolvidas com a ativa??o deste processo, sugerindo a ativa??o de um circuito anti-apopt?tico nesta linhagem, o que pode ajudar a explicar a alta susceptibilidade de indiv?duos XPC a desenvolvimento de c?nceres. Estes resultados tamb?m contribuir?o para o esclarecimento dos mecanismos de atua??o de NER em danos oxidativos e para a compreens?o de vias importantes na correla??o do estresse oxidativo, reparo e forma??o de tumores mal?gnos

Full textAbstract:
Mitochondria are the organelles where respiration occurs. The yeast mitochondrial genome encodes only 8 proteins, therefore the organelle depends on the nuclear genome for many proteins required in different steps of mitochondrial gene expression. Regulation of mRNA stability, processing and translation are important steps in gene expression within the mitochondrion. Cbp1, a protein encoded by the nuclear gene CBP1, is required specifically for stabilization of precursor and mature cytochrome b (COB) RNA, which is encoded in the mitochondrial genome. Previous work identified a cis-element, CCG, in the 5' untranslated region (UTR) of COB, that is critical for the Cbp1-dependent stability of COB mRNA. Mutation of any single nucleotide resulting in an A̲CG, CA̲G or CCU̲ triplet causes destabilization of COB mRNA and concomitant loss of respiratory capability. In the present study, suppressors were selected in the CCU strain in an effort to define important sites in Cbp1 for protection of COB mRNA. The mitochondrial mutant strain CCU is conditional; it grows slowly at 25°C but does not grow at 18°C or 33°C on the non-fermentable carbon source glycerol. Twelve dominant suppressors in CBP1 were obtained. They define two main groups, based on the pattern of growth on glycerol at different temperatures. The CBP1-encoded suppressors make strains containing the mitochondrial CCU̲ mutation respiratory competent at 33°C by allowing accumulation of mature COB mRNA. Suppressors that map to the carboxyl half of Cbp1, such as S289G, S330R, Q358K, Q358R, L489W, K532M, D533Y and I638M, rescue the temperature-sensitive (ts) phenotype caused by the CCU̲ mutation. The suppressors that map to the amino half of Cbp1, such as K205R, E241G, I249T, N281D and I293L, rescue the ts phenotype to a lesser extent than the suppressors that map to the carboxyl half of Cbp1. These results suggest that the two halves of Cbp1 have different functions in the processing and stability of COB transcripts. The hypothesis that Cbp1 has a role in translation of cytochrome b (COB) mRNA was not testable previously, since disruption of CBP1 results in instability and degradation of COB mRNA. In a Δpet127 strain, COB precursor mRNA is not processed to the mature 5' site and thus accumulates to levels equivalent to that of the wild-type mature mRNA (Wiesenberger and Fox, 1997). Null alleles of pet127 were selected as suppressors of A̲CG and CCU̲ mutations in COB. COB precursor mRNA levels in these strains were similar to the Δpet127 strain with a wild-type mitochondrial genome (Chen et al., 1999). In the present study, the effect of deleting CBP1 in a Δpet127 strain was measured. Strain Δcbp1 Δpet127 accumulated no mature COB mRNA but high levels of COB precursor mRNA. The levels of precursor mRNA in the Δcbp1 Δpet127 strain were 3-fold higher than in wild-type strain and approaching 60% of wild-type mature levels (wild-type COB precursor is 18% of mature COB mRNA). Absolutely no apocytochrome b protein was detected in the Δcbp1 Δpet127 strain. This result suggests that Cbp1 is required for translation of the COB message. Future experiments to determine the role of Cbp1 in the translation of COB mRNA are described.

Full textAbstract:
Volvo Group’s cab plant in Umeå produces cab bodies and consists of three operating areas; the Stamping and parts production, the Body in White and the Paint shop. Today the plant produces around XXX cabs/week, but the goal is to reach the invested capacity of XXX cabs/week. In order to increase the production capacity, the efficiency of both the manual and the automated processes need to be improved. Unlike the manual processes in where the capacity can be increased by enlarged workforce, the automated processes need to be optimized. Today the cabs are produced in the same order as the orders are received. The cab plant wants to investigate if the capacity of the automated segment in the Body in White unit can be increased by changing the order in the production sequence. This culminates in the following problem definition: Is there untapped potential of the Body in White that can be achieved by an optimization of the production sequence? If so, how can Volvo Group’s cab plant in Umeå utilize this knowledge in the production planning process? The objective of the project was achieved by combining discrete event simulation with a heuristic optimization approach. The results shows that long batches in the production sequence limit the throughput of the system. By spreading the unfavorable subsequences of batches evenly over the production sequence, the total throughput of the Body in White can be increased by 52 cabs/week.Volvokoncernens hyttfabrik i Umeå producerar förarhytter och är uppdelad i tre driftsområden; pressning och detaljtillverkning, hyttsammansättning och ytbehandling. Idag producerar fabriken ca XXX hytter/vecka, men möjlighet finns att nå upp till den investerade kapaciteten på XXX hytter/vecka. För att kunna öka produktionskapaciteten behöver både de manuella och de automatiserade processerna effektiviseras. Till skillnad från de manuella processerna, där kapaciteten kan ökas genom att öka antalet operatörer, behöver de automatiserade processerna optimeras. Idag produceras hytterna i samma ordning som beställningarna kommer in. Hyttfabriken vill undersöka om det finns en möjlighet att öka kapaciteten för den automatiserade processen i Body in White genom att optimera produktionssekvensen. Detta leder fram till följande problemformulering: Finns det outnyttjad potential i Body in White som kan uppnås genom att optimera produktionssekvensen? Hur kan Volvokoncernens hyttfabrik i Umeå utnyttja denna kunskap vid planering av produktionen? Målet med projektet har uppnåtts genom att kombinera diskret händelsesimulering med optimering genom heuristiker. Resultatet visar att stora batcher av samma variant i produktionen begränsar genomströmningen i processen. Genom att bland annat sprida ut de ogynnsamma delsekvenserna jämnt över produktionssekvensen kan den totala genomströmningen i Body in White ökas med 52 hytter/vecka.

Full textAbstract:
Nordic Cab AB är ett företag som säljer multifunktionella barnvagnar. Dessa barnvagnar har utbytbara delar vilket gör att man kan omvandla dem till en jogging-, cykel-, skid-, hund- eller vandringsvagn.
Syftet med denna uppsats är att prissätta Nordic Cab AB:s multifunktionella barnvagn. För att uppnå detta beskriver vi först hur olika faktorer påverkar Nordic Cab AB:s prissättning. Dessa faktorer är företagets mål, kostnader, efterfrågan och konkurrenter. Utifrån dessa faktorer och intervjuer med återförsäljare av multifunktionella barnvagnar och VD:n för Nordic Cab AB kommer vi fram till att Nordic Cab AB borde använda sig av en prissättningsmetod som baseras på upplevt kundvärde.
Genom att låta återförsäljare av multifunktionella barnvagnar betygsätta hur viktiga olika egenskaper hos dessa är för kunden och hur bra de olika företagen på marknaden är på att tillgodose dessa egenskaper kan vi presentera ett kundvärde för Nordic Cab AB och två av deras konkurrenter. Vi jämför dessa och kommer fram till att skillnaden i erbjudet kundvärde mellan Nordic Cab AB och Företag A (som tar ett högre pris) inte reflekterar prisskillnaden mellan de båda. Därför rekommenderar vi Nordic Cab AB att höja sitt pris så att det ligger närmare Företag A:s.
Nordic Cab AB is a company which sells multifunctional children strollers. These strollers have replaceable parts which makes it possible to transform them into a jogging-, bicycle-, ski-, dog- or hiking trailer.
The purpose of this thesis is to price Nordic Cab AB's multifunctional stroller. In order to achieve this we first describe how different factors affect Nordic Cab AB's pricing. These factors are the company's goal, costs, demand and competition. From these factors and interviews with retailers of multifunctional strollers and the CEO of Nordic Cab AB we reach the conclusion that Nordic Cab AB should use a pricing method which is based on perceived customer value.
By letting retailers of multifunctional strollers grade how important different abilities of these are to the customer and how good the different companies on the market are at supplying these abilities, we can present a figure of customer value for Nordic Cab AB and two of their competitors. We compare these and reach the conclusion that the difference in customer value offered between Nordic Cab AB and Company A (which charges a higher price) does not reflect the difference in price between the two. Therefore we recommend Nordic Cab AB to raise their price to approach Company A's.

Full textAbstract:
In this thesis we will present a comprehensive set of formalisms for comparing, evolving, and constraining primordial non-Gaussian models through the CMB bispectrum. First, we introduce the idea of a shape function for characterising the primordial non-Gaussianity. The shape function can also be used to construct a correlator between the models which we use to group the space of possible models into four main classes: equilateral, squeezed, flattened, and scale dependent. Next, we use a common property of the shape function to create a method for calculating, without approximation, the CMB bispectrum from a general primordial model. There are two techniques we use to speed up the calculation. The first is to use the flat sky approximation for large l, and the second is to exploit the smoothness of the reduced bispectrum to calculate the bispectrum first on a sparse grid then interpolate to obtain the remaining points. We then discuss methods for calculating estimators by decomposing the bispectrum, either today or at primordial times, into the product of eigenmodes. First we deal with the primordial bispectrum and describe how the decomposition can be used to both constrain primordial models and to estimate the primordial bispectrum from observations. Then we repeat the analysis for the CMB bispectrum and describe how this process can be used to constrain models, but this time allowing for the inclusion of late time effects. It also presents a method for generating maps with an arbitrary bispectrum and power spectrum.

Full textAbstract:
This thesis presents a product development process, where an existing solution on a cab door have been analysed and developed, with the aim to result in a cost-effective concept solution for handling tolerances on the door frame. The methodological approach in this thesis is based on Volvo Construction Equipment’s development model; The Global Development Process, which started with a pre-study phase where the problem formulation was established. The problem formulation in short is to find a solution for how to handle narrow tolerances in steel profiles for the door weldment on cab doors. Various solution ideas were discussed and concepts were generated with focus to design a new cab door corner that would solve the problems addressed by the project. The applied method resulted in a final concept consisting of the same steel profiles but with new dimensions, and two new concepts in each corner; one corner module that is placed inside the steel profiles and joined by welding, and a plastic shell that covers the welded corner. The concept was validated using a prototype of the proposed solution, where tests show that the requirements were achieved, besides a few deficiencies. A cost comparison between the existing and the proposed solution was made within limitations for this thesis. The result of the cost comparison shows an indication of that the proposed solution can be more cost-effective than the existing solution. Some of the recommendations after have completing the project are to make a complete cost comparison to ensure that the indication is correct and to analyse the new components to optimize and define the dimensions of them.

A diminuição no tamanho dos transistores vem aumentando cada vez mais o número de funções que os dispositivos eletrônicos podem realizar. Apesar da diminuição do tamanho mínimo dos transistores, a velocidade máxima dos circuitos não consegue seguir a mesma taxa de aumento. Um dos grandes culpados apontados pelos pesquisadores são as interconexões entre os transistores e também entre os componentes. O aumento no número de interconexões dos circuitos traz consigo um significativo aumento do cosumo de energia, aumento do atraso de propagação dos sinais, além de um aumento da complexidade e custo do projeto dos circuitos integrados. Como uma possível solução a este problema é proposta a utilização de lógica multivalorada, mais especificamente, a lógica quaternária. Os dispositivos FPGAs são caracterizados principalmente pela grande flexibilidade que oferecem aos projetistas de sistemas digitais. Entretanto, com o avanço nas tecnologias de fabricação de circuitos integrados e diminuição das dimensões de fabricação, os problemas relacionados ao grande número de interconexões são uma preocupação para as próximas tecnologias de FPGAs. As tecnologias menores que 90nm possuem um grande aumento na taxa de erros dos circuitos, na lógica combinacional e sequencial. Apesar de algumas potenciais soluções começara a ser investigadas pela comunidade, a busca por circuitos tolerantes a erros induzidos por radiação, sem penalidades no desempenho, área ou potência, ainda é um assunto de pesquisa em aberto. Este trabalho propõe o uso de circuitos quaternários com modificações para tolerar falhas provenientes de eventos transientes. Como principal contribuição deste trabalho destaca-se o desenvolvimento de uma CLB (do inglês Configurable Logic Block) quaternária capaz de suportar eventos transientes e, na possibilidade de um erro, evitá-lo ou corrigi-lo.The decrease in transistor size is increasing the number of functions that can be performed by the electronic devices. Despite this reduction in the transistors minimum size, the circuit’s speed does not follow the same rate. One of the major reasons pointed out by researchers are the interconnections between the transistors and between the components. The increase in the number of circuit interconnections brings a significant increase in energy consumption, propagation delay of signals, and an increase in the complexity and cost of new technologies IC designs. As a possible solution to this problem the use of multivalued logic is being proposed, more specifically, the quaternary logic. FPGA devices are characterized mainly by offering greater flexibility to designers of digital systems. However, with the advance in IC manufacturing technologies and the reduced size of the minimum fabricated dimensions, the problems related to the large number of interconnections are a concern for future technologies of FPGAs. The sub 90nm technologies have a large increase in the error rate of its functions for the combinational and sequential logic. Although potential solutions are being investigated by the community, the search for circuits tolerant to radiation induced errors, without performance, area, or power penalties, is still an open research issue. This work proposes the use of quaternary circuits with modifications to tolerate faults from transient events. The main contribution of this work is the development of a quaternary CLB (Configurable Logic Block) able to withstand transient events and the occurrence of soft errors.

This dissertation discusses the Humor in the media and their interaction with culture and social imaginary, it is a study of the program Custe o que Custar (CQC), broadcasted by Bandeirantes television network. Describes the evolution of humor in Western history, its relations with the cultures and their foray in the media, in the nineteenth century. Maps the humor present in the Brazilian media in XX and XXI centuries and presents a categorization of television comedy. About television program studied rescued up your history, from its origins in Brazil until today. It has been shown through literature, the process of mediatization of society and the creation of individual and social identities, guided by the production of consumer goods. There was integration among symbolic values of culture, media and social imaginary. We conclude by analyzing the program that humor is an important discursive element in the spread of ideas and values and can be both a transforming element when in accordance with the prevailing social structures. Also, the CQC is one element among many media products, which act as social agents to act in the construction of symbolic values and the social imaginary. In the case studied, the information is confused with entertainment, resulting in a hybrid characteristic of contemporary mediated culture.
Esta dissertação aborda o humor na mídia e sua interação com a cultura e o imaginário social, a partir de um estudo do programa Custe o que Custar (CQC), da rede Bandeirante de televisão. Inicialmente descreve a evolução do humor na história ocidental, suas relações com as culturas e sua incursão na mídia, a partir do século XIX. Num segundo momento mapeia o humor presente na mídia brasileira nos séculos XX e XXI e apresenta uma categorização de programas humorísticos televisivos. Em relação ao programa televisivo estudado, resgatou-se o seu histórico, desde a sua origem no Brasil até o início do ano de 2013. Demonstrou-se por meio de levantamento bibliográfico o processo de midiatização da sociedade e a criação de identidades individuais e sociais, pautadas pela produção de bens de consumo. Por meio de uma análise descritiva, pode-se verificar a integração entre valores simbólicos da cultura, mídia e imaginário social. Concluiu-se, pela análise do programa, que o humor é elemento discursivo importante na propagação de ideias e valores, e pode ser elemento tanto de transformação quando de conformidade com as estruturas sociais dominantes. Também, que o CQC é mais um elemento dentre diversos produtos midiáticos, que funcionam como agentes sociais a atuar na construção de valores simbólicos e no imaginário social. Ainda, que no caso estudado, a informação se confunde com o entretenimento, resultando em um produto híbrido característico da cultura midiatizada contemporânea.

Mestrado em Ensino de Física e de QuímicaNos dias de hoje, a Escola não pode alhear-se aos novos fenómenos sociais e tem de ser capaz de se flexibilizar de modo a acompanhar a sociedade moderna, já que a globalização gera a necessidade de acabar com esquemas rígidos e únicos. Neste contexto, os professores devem ter práticas curriculares guiadas pela selectividade, essencialidade e adequação, pelo que lhes cabe decidir: o que ensinar, quando ensinar e como ensinar. A emergência de uma nova cultura de Escola, em que se desenvolva um trabalho cooperativo entre os docentes da mesma área disciplinar, do mesmo ano escolar e entre os professores dos vários níveis sequenciais de ensino, é necessária para concretizar um novo paradigma de Escola. Surge assim a interdisciplinaridade como tentativa de superar uma visão fragmentária dos objectos e dos acontecimentos através da confrontação de olhares plurais na sua observação. São intenções deste estudo investigar a compreensão que os professores de Ciências Físico-Químicas, a leccionar no 3.º Ciclo do Ensino Básico, têm sobre a interdisciplinaridade e analisar as suas perspectivas. Para tal, desenvolveu- -se um estudo ideográfico, de natureza qualitativa. Como instrumento de recolha de dados recorreu-se a um questionário escrito, de resposta individual, dirigido a uma amostra reduzida de 24 professores, constatando-se, que a maioria dos docentes conhece o significado do termo interdisciplinaridade. Por outro lado, os inquiridos apontam como principais dificuldades à aplicação de uma prática interdisciplinar no seio escolar os seguintes factores: toda a escola estar organizada disciplinarmente, a forma de divisão do tempo e do espaço, a formação inicial dos professores e o desinteresse destes em participar em situações que se afastem do ensino dito tradicional. O presente estudo pretende ainda criar modelos (propostas de recursos didácticos) de como se podem construir pontes (articulações) entre os diversos ramos do saber de forma contextualizada, através de processos cooperativos e interactivos, utilizando uma linguagem partilhada pelas diversas disciplinas intervenientes. Dadas as circunstâncias que envolvem actualmente a colocação de professores, condicionando, à partida, a caracterização da área sócio- -geográfica e cultural da população estudantil em que o professor se vai inserir, criou-se uma situação que possa proporcionar experiências activas, significativas, diversificadas, integradas e socializadoras, e que seja transponível para outros contextos e circunstâncias lectivas. Para tal, escolheu-se como situação-problema a tratar interdisciplinarmente: “Será viável a produção de Vinho da Bairrada noutra região do país?”, com base no conhecimento profundo da área de origem da docente, e foram desenvolvidos recursos didácticos para a tratar. Estes foram validados por professores a leccionar, no ano lectivo 2004/2005, ao 8.º ano de escolaridade, as disciplinas envolvidas, na área geográfica em que a autora foi colocada, não só como forma de operacionalizar o trabalho e testar da versatilidade do tema escolhido, mas também como meio de averiguar a viabilidade da proposta de trabalho. Verificou-se, então, que os professores inquiridos se mostraram receptivos e disponíveis para a implementar no próximo ano lectivo. Pese embora as limitações do estudo, considera-se que ele dá um contributo relevante quer para professores quer para investigadores, nomeadamente no que respeita à operacionalização de situações de interdisciplinaridade possíveis de serem aplicadas em sala de aula, dado que aqui se alia a teoria à prática, no sentido de melhorar as aprendizagens dos alunos, aplicando simultaneamente as principais perspectivas de ensino das Ciências. O trabalho termina com sugestões para futuros trabalhos, no mesmo contexto. ABSTRACT: Nowadays, school cannot be alienated from new social phenomena. In fact, it should be able to adapt itself to today’s society since globalisation generates the necessity to bring an end to narrow-minded views. In this context, teachers must adopt curricular practices that are guided by selectivity, essentiality and suitability, so that they can decide what, when and how they teach. The emergence of a new school, where a cooperative work between teachers of the same subject area, the same school year and between teachers of the several sequential school years must occur, is necessary to reach a new paradigm of school. So, interdisciplinarity arises as an attempt to overcome a fragmentary vision of objects and events, through the confrontation of plural views in their observation. This study means to investigate the understanding that Physics and Chemistry teachers, giving lessons in the third stage of the basic education, have about interdisciplinarity and to analyse their perspectives. Thus, an ideographic qualitative study has been developed. I had recourse to a written questionnaire of individual answer, which was directed to a reduced sample of 24 teachers as a data recollection instrument. In the one hand, it has been concluded that most of the teachers know the meaning of the term interdisciplinarity. In another hand, the respondents point out the following reasons as main difficulties found in the application of an interdisciplinary practise at school: the entire school is organized disciplinary, the way space and time are divided, the initial preparation of teachers and the disinterest of these latter in getting involved in situations that are different from the so-called traditional teaching practices. This study also aims to create models (proposals of didactic resources) of how bridges can be built (articulations) from the several branches of knowledge, in a contextualized way, through cooperative and interactive processes, by making use of a language that is shared by the several involved subjects. In virtue of the instability of the labour market that many teachers are facing at present in Portugal, educators have difficulties in characterising the new socialgeographical and cultural environment (year after year). Giving this, a new position that enables active, significant, diversified, integrated and socializing experiences arises and this latter has positive effects since it is transferable to other geographical and teaching circumstances. In order to achieve this goal, a problem-situation, to be treated interdisciplinary has been created: “Would it be viable to produce Vinho da Bairrada in any other region than Bairrada?”. This situation has been chosen because of the deep insight each teacher has of the place he/she lives in and didactic recourses have been developed to lead with it. Educators that are teaching the involved subjects of the 8th grade in Castelo de Paiva (city where the author is working) have validated these didactic resources, not only as a way to make the procedures operational and to test the versatility of the chosen topic, but also to check the viability of the work proposal. It has been concluded that the teachers who answered the questionnaire are willing to implement the problem-situation in the following school year. Although there are limitations to the study, it is clear that it provides a relevant contribution either for teachers or researchers, namely in what concerns the operationalization of interdisciplinary situations possible to be applied in real class contexts. In fact, in this case, theory allies with practise in order to improve the students’ learning, applying simultaneously the main perspectives of Sciences teaching. This study ends with suggestions for future works, in the same context.

Mestrado em Ensino de Física e QuímicaO contexto deste estudo tem em consideração o reconhecimento generalizado do decisivo papel da educação na promoção do Desenvolvimento Sustentável. Por isso as Nações Unidas decidiram declarar o período entre 2005 e 2014 como Década das Nações Unidas para a Educação para o Desenvolvimento Sustentável. Considerando por um lado as potencialidades educacionais do tópico, e por outro a sua assumida complexidade, é fundamental dar uma particular atenção ao papel desempenhado pelos professores na forma como procedem à respectiva abordagem, conhecendo-se aliás da literatura de investigação educacional a forma como as percepções dos docentes influenciam as respectivas práticas lectivas. Nesse sentido, pretendeu-se com este trabalho analisar as principais concepções dos professores que leccionam Ciências Físico-Químicas, no 3º CEB, sobre o conceito de Sustentabilidade assim como alguns aspectos relacionados com as suas práticas lectivas. A técnica de recolha de dados utilizada foi o inquérito por questionário. A amostra é constituída por 46 professores a leccionar na região centro do país. Para o tratamento de dados recorremos à análise estatística e à análise de conteúdo. As principais conclusões confirmam o referido na literatura sobre a excessiva importância atribuída à vertente ambiental dos professores em detrimento das restantes dimensões. A influência destas concepções na sua prática educativa não pode ser inteiramente comprovada embora seja notória a falta de formação dos professores nesta área. ABSTRACT: The context of this study is the generalized recognition of the decisive role, played by education in the promotion of Sustainable Development. Therefore, the United Nations decided to proclaim the period between 2005 and 2014 as the United Nations Decade of the Education for the Sustainable Development. Considering the educational potential of the topic, and the recognized complexity, it is important to give particular attention to educational approaches.
