Full textAbstract:
Slag has been used in concrete as a cementitious extender for about 50 years in South Africa. Traditionally, blastfurnace slag has been used in concrete but recently a new product called Ground Granulated Corex Slag (GGCS) has become available on the market in the Western Cape Province. The objective of this research is to characterise the properties of this new product in concrete. In this study, the properties of corex slag concrete were compared to normal blastfurnace slag and plain CEM I concretes. A series of mixes was undertaken, with water:binder ratios varying between 0.4 and 0.3, and slag replacement levels between 30 and 70%. The physical characterisation of corex slag revealed that the material is finer than blastfurnace slag, having more ultra-fine particles. The oxide analysis showed that the higher proportions of the calcium and magnesium oxides present in corex slag increase the potential for hydraulic activity of the binder compared with blastfurnace slag. The investigation of the fresh concrete properties revealed that the consistence of concrete increases with the use of slag, especially at higher water:binder ratios. Blastfurnace slag performed marginally better than corex slag. The use of slag generally increased the setting time of the paste, with pastes containing corex slag having a shorter final setting time than those containing blastfurnace slag. The setting time was also found to increase with increasing stag replacement level. The increase in setting time caused the bleed time of slag concrete to increase but the total bleed volume was significantly reduced. The bleed properties of concrete were improved when corex slag was used. It was found that the compressive strength of the new cementitious material lagged behind that of CEM I controls during early ages but after seven days, corex slag concrete showed higher strength. The strength was observed to decrease with increasing water:binder ratio. From the compressive strength results, it was deduced that the optimum corex slag substitution rate varied with water:binder ratio, ranging from 45 to 60 % The elastic modulus of corex slag concrete was found to be equal to or higher than CEM I concrete, especially at low water:binder ratios (wtb = 0.4). Deformation experiments showed that corex slag concrete had the lowest creep and shrinkage strains of all the concretes at low water:binder ratios. At higher water:binder ratios, however, the shrinkage strains were in the same range as the other two materials. Prediction models were also assessed and it was found that no model was able to accurately predict both creep and shrinkage. Generally, the shrinkage predictions were more accurate. Durability index tests showed that corex slag concrete has good to excellent potential durability, based on historical data. Marine exposure testing indicated that corex slag binds a substantial amount of chlorides, hence reducing the risk of corrosion in marine environments. Furthermore, the risk of carbonation-induced corrosion is also decreased. Expansion associated with alkali-silica reaction is minimised with the use of corex slag and the efficiency of the material increases with replacement level. It is concluded that corex slag is an excellent extender for use in concrete. Finally, recommendations are made on the need to further characterise the properties of the material.

Full textAbstract:
Many-core architectures are more promising hardware to design real-time systems than multi-core systems as they should enable an easier mastered integration of a higher number of applications, potentially of different level of criticalities. In embedded real-time systems, these architectures will be integrated within backbone Ethernet networks, as they mostly provide Ethernet controllers as Input/Output(I/O) interfaces. Thus, a number of applications of different level of criticalities could be allocated on the Network-on-Chip (NoC) and required to communicate with sensors and actuators. However, the worst-case behavior of NoC for both inter-core and core-to-I/O communications must be established. Several NoCs targeting hard real-time systems, made of specific hardware extensions, have been designed. However, none of these extensions are currently available in commercially available NoC-based many-core architectures, that instead rely on wormhole switching with round-robin arbitration. Using this switching strategy, interference patterns can occur between direct and indirect flows on many-cores. Besides, the mapping over the NoC of both critical and non-critical applications has an impact on the network contention these core-to-I/O communications exhibit. These core-to-I/O flows (coming from the Ethernet interface of the NoC) cross two networks of different speeds: NoC and Ethernet. On the NoC, the size of allowed packets is much smaller than the size of Ethernet frames. Thus, once an Ethernet frame is transmitted over the NoC, it will be divided into many packets. When all the data corresponding to this frame are received by the DDR-SDRAM memory on the NoC, the frame is removed from the buffer of the Ethernet interface. In addition, the congestion on the NoC, due to wormhole switching, can delay these flows. Besides, the buffer in the Ethernet interface has a limited capacity. Then, this behavior may lead to a problem of dropping Ethernet frames. The idea is therefore to analyze the worst case transmission delays on the NoC and reduce the delays of the core-to-I/O flows. In this thesis, we show that the pessimism of the existing Worst-Case Traversal Time (WCTT) computing methods and the existing mapping strategies lead to drop Ethernet frames due to an internal congestion in the NoC. Thus, we demonstrate properties of such NoC-based wormhole networks to reduce the pessimism when modeling flows in contentions. Then, we propose a mapping strategy that minimizes the contention of core-to-I/O flows in order to solve this problem. We show that the WCTT values can be reduced up to 50% compared to current state-of-the-art real-time packet schedulability analysis. These results are due to the modeling of the real impact of the flows in contention in our proposed computing method. Besides, experimental results on real avionics applications show significant improvements of core-to-I/O flows transmission delays, up to 94%, without significantly impacting transmission delays of core-to-core flows. These improvements are due to our mapping strategy that allocates the applications in such a way to reduce the impact of non-critical flows on critical flows. These reductions on the WCTT of the core-to-I/O flows avoid the drop of Ethernet frames.

Full textAbstract:
Deposition of silica shells onto ZnO nanoparticles (NPs) in dimethyl sulfoxide was found to be an efficient tool for terminating the growth of ZnO NPs during thermal treatment and producing stable core–shell ZnO NPs with core sizes of 3.5–5.8 nm. The core–shell ZnO–SiO2 NPs emit two photoluminescence (PL) bands centred at [similar]370 and [similar]550 nm originating from the direct radiative electron–hole recombination and defect-mediated electron–hole recombination, respectively. An increase of the ZnO NP size from 3.5 to 5.8 nm is accompanied by a decrease of the intensity of the defect PL band and growth of its radiative life-time from 0.78 to 1.49 μs. FTIR spectroscopy reveals no size dependence of the FTIR-active spectral features of ZnO–SiO2 NPs in the ZnO core size range of 3.5–5.8 nm, while in the Raman spectra a shift of the LO frequency from 577 cm−1 for the 3.5 nm ZnO core to 573 cm−1 for the 5.8 nm core is observed, which can indicate a larger compressive stress in smaller ZnO cores induced by the SiO2 shell. Simultaneous hydrolysis of zinc(II) acetate and tetraethyl orthosilicate also results in the formation of ZnO–SiO2 NPs with the ZnO core size varying from 3.1 to 3.8 nm. However, unlike the case of the SiO2 shell deposition onto the pre-formed ZnO NPs, individual core–shell NPs are not formed but loosely aggregated constellations of ZnO–SiO2 NPs with a size of 20–30 nm are. The variation of the synthetic procedures in the latter method proposed here allows the size of both the ZnO core and SiO2 host particles to be tuned<br>Dieser Beitrag ist aufgrund einer (DFG-geförderten) Allianz- bzw.

Full textAbstract:
Dopamine is implicated in the responsiveness to rewarding properties of natural and pharmacological stimuli. Conditioned stimuli (CS), linked to rewards such as food or drugs of abuse (uncontidioned stimuli, US), are essential to support the motivated behaviour. The role of mesocortical and mesolimbic DA in response to food CS after instrumental paradigm still remains unclear.
The aim of our study was to investigate by microdialysis the impact of instrumental food CSs and US on behaviour and on basal DA in three terminal DA areas: shell and core of nucleus accumbens (NAc) and medial prefrontal cortex (mPFCX), using a food self-administration paradigm.
Rats were trained to acquire sucrose self-administration under a Fixed Ratio 1 (FR 1) or FR5 variable time out schedule of responding.
After training, animals were able to self-administer sucrose pellets and microdialysis coupled with self-administration experiments were performed..
The main finding of our study was that NAc shell DA has been activated not only by the conditioned cues but also by food after the instrumental conditioning. When both stimuli are presented in the same moment the increase of DA is strengthened and prolonged. DA response was obtained in NAc core only during US presentation. mPFCX has been activated by each component of motivated behaviour, except for the response to CS using a FR5 schedule.
We can conclude that DA in the NAc shell plays an important role on the acquisition and expression of motivated behaviour in food consumption, whereas NAc core and PFCX are less implicated.
This study provides a robust and reproducible model for a parametric study of the relationship between behaviour and DA transmission in the NAc shell and core and in the mPFCX .

Full textAbstract:
A new whole-core transport method is described for 3-D hexagonal geometry. This is an extension of a stochastic-deterministic hybrid method which has previously been shown highly accurate and efficient for eigenvalue problems. Via Monte Carlo, it determines the solution to the transport equation in sub-regions of reactor cores, such as individual fuel elements or sections thereof, and uses those solutions to compose a library of response expansion coefficients. The information acquired allows the deterministic solution procedure to arrive at the whole core solution for the eigenvalue and the explicit fuel pin fission density distribution more quickly than other transport methods. Because it solves the transport equation stochastically, complicated geometry may be modeled exactly and therefore heterogeneity even at the most detailed level does not challenge the method. In this dissertation, the method is evaluated using comparisons with full core Monte Carlo reference solutions of benchmark problems based on gas-cooled, graphite-moderated reactor core designs. Solutions are given for core eigenvalue problems, the calculation of fuel pin fission densities throughout the core, and the determination of incremental control rod worth. Using a single processor, results are found in minutes for small cores, and in no more than a few hours for a realistically large core. Typical eigenvalues calculated by the method differ from reference solutions by less than 0.1%, and pin fission density calculations have average accuracy of well within 1%, even for unrealistically challenging core configuration problems. This new method enables the accurate determination of core eigenvalues and flux shapes in hexagonal cores with efficiency far exceeding that of other transport methods.

Full textAbstract:
Sandwich Panels with cellular cores are widely used in the aerospace industry for their higher stiffness to mass, strength to mass ratio, and excellent energy absorption capability. Even though, sandwich panels are considered state of the art for lightweight aerospace structures, the requirement to further reduce the mass exists due to the direct impact of mass on mission costs.
Traditional manufacturing techniques have limited the shape of the cores to be either hexagonal or rectangular, but, with rapid advancements in additive manufacturing, other core shapes can now be explored. This research aims to identify and evaluate the mechanical performance of two-dimensional cores having standard wall geometry, which provide higher specific stiffness than honeycomb cores. Triangular cores were identified to have higher specific in-plane moduli and equivalent specific out-of-plane and transverse shear moduli. To consider practical use of the triangular cores, elastic and elastic-plastic structural analysis was performed to evaluate the stiffness, strength, failure, and energy absorption characteristics of both the core and sandwich panels. The comparison made between triangular cores and hexagonal cores having the same cell size and relative density showed that triangular cores outperform hexagonal cores in elastic range and for applications where in-plane loading is dominant. Triangular cores also have excellent in-plane energy absorption capabilities at higher densities.<br>Master of Science

Full textAbstract:
The widespread appearance of Levallois technology approximately 300,000 years ago in Europe and Africa is associated with significant behavioural and cognitive changes. The origins of this technique, however, are still highly debated. Fully developed Levallois reduction sequences seem to have their roots in a lesser-understood technique referred to as either ‘proto’, or ‘reduced’ Levallois, and more recently as Simple Prepared Core (SPC) technology. This thesis examines the technological relationship between SPCs and the Levallois technique in eight British and two Belgian assemblages. Whilst exploring the significance of the presence of SPC technology in the Lower Palaeolithic archaeological record of northwest Europe, this research also assesses the implications for hominin behaviour and cognition. Results demonstrate identical reduction techniques at nine of the ten sites studied, allowing for the construction of a new overarching technological definition of SPC technology, which is now accepted to be present on a significantly wider scale both temporally and geographically. A clear conceptual link between SPC technology and the Levallois technique is apparent regarding the approach to the volume of the core and the targeted end product. However the lack of shaping of the preferential flaking surface prevents the SPC end products from being considered predetermined. As it is the predetermination of the final product that is linked with the cognitive complexity required to implement the Levallois technique, the hominins responsible for SPCs cannot be considered to demonstrate the same level of cognition as those with Levallois technology. The implications of these results suggest hominins using the SPC technique were conceptually on the path towards the Levallois technique but cannot be considered to demonstrate the same behavioural and cognitive capacity.

Il est classiquement admis que le cortex moteur des primates est organisé topographiquement en lien avec le contrôle des différentes parties du corps. Il a également été suggéré que différentes zones de cette aires corticales pourraient être impliquées dans différents processus de préparation motrice. Suivant cette dernière hypothèse, cette thèse a pour objectif d’étudier les modulations spatiales et temporelles de l’activité neuronale du cortex moteur au cours de la préparation et de l’exécution de mouvements de saisie manuelle. Trois singes ont été entraînés à réaliser une tâche pré-indicée de saisie manuelle. Chez chaque animal, une matrice d’électrodes a été implantée chroniquement dans le cortex moteur. Dans une première étude, nous avons démontré que les modulations d’activité associées à différents processus préparatoires sont localisées dans différentes zones du cortex moteur. Ces zones seraient activées séquentiellement au cours de la préparation motrice suivant une alternance de phases de traitement stationnaire et de propagation dynamique. Dans une seconde étude, nous avons exploré les interactions neuronales par l’utilisation de la mesure de corrélation de variabilité (rsc) entre paires de neurones. Cette deuxième étude a fait ressortir 3 résultats principaux. Les valeurs de rsc sont plus élevées au cours de la préparation du mouvement que lors de son exécution. Elles diminuent avec la distance qui sépare les neurones. Elles sont plus importantes entre interneurones qu’entre neurones supposés pyramidaux. L’ensemble de ces observations ont été discutées en lien avec différentes modèles d’organisation spatiale des aires motrices corticales<br>The motor cortex follows a somatotopic organization in which the different body parts are controlled by distinct cortical zones. It has also been proposed that different spatial zones of this cortical area could be involed in distinct processes of motor preparation. Following this latter hypothesis, the objective of this thesis is to study the spatio-temporal modulations of motor cortex activity during movement preparation and execution. Three monkeys have been trained in an instructed delayed reach-to-grasp task. In each animal, a multielectrode Utah array was chronically implanted in the motor cortex to explore the dynamic modulations of neural activity during task performance. In a first study, we demonstrated that the modulations of neural activity related to distinct processes of motor preparation occur at different cortical locations. These locations are activated sequentially during motor preparation through alternating phases of stationary processing and dynamic propagation. In a second study, we analysed the neural interactions using a measure of spike count correlation (rsc) between pair of neurons. We reported 3 main results. Correlations are higher during movement preparation than during execution. They decrease with the distance between neurons. Finally, they are higher bewteen putative interneurons than bewteen putative pyramidal neurones. All these observations are discussed in relation to several models of the spatial organization the motor cortex

A luz é considerada como a energia que sustenta a vida. Toda a informação que nós captamos e a percepção dos objectos depende especialmente da natureza das imagens que são formadas nos nossos olhos. Sabemos que através da luz recebemos grandes quantidades de informação do mundo que nos rodeia e para vermos as imagens e os objectos necessitamos de um sistema visual. Podemos dizer que a cor apresenta um papel importante para a nossa sobrevivência (por exemplo: alguns seres vivos como é o caso de algumas aves que apresentam algumas cores nas suas plumagens que é muito importante para elas). É um fenómeno físico expressivo e simbólico de importância fundamental na linguagem visual. Por vezes pode-se tratar de um conceito subjectivo que consiste na interpretação que o sistema sensorial e o cérebro atribuem aos diferentes comprimentos de onda da luz recebida.
Ver é para nós, um fenómeno tão natural que se torna necessário um esforço de imaginação para concebermos que tal fenómeno inclui a solução de certos problemas. O olho é um dos órgãos mais importantes do corpo humano, são os responsáveis pela captação da informação proveniente do meio exterior e pela sua codificação, em impulsos nervoso através da acção de células nervosas especializadas. Trata-se de um órgão fantástico e bastante complexo, considerando um prolongamento do tecido cerebral. Até ao século XVI pensava-se erroneamente que o olho emitisse luz, hoje sabemos que ele apenas é um receptor.
Com este trabalho pretende-se descrever de forma sucinta, como o ser humano consegue discriminar e identificar as cores, abordar algumas teorias da cor, descrever o funcionamento do processo visual e apresentar algumas anomalias da visão das cores.<br>The light is regarded as the energy that supports life. Every information that we attract and
the perception of objects especially depends on the nature of the images that are formed in
our eyes. We know that through light we receive large amounts of information from the
world around us and to see those images and objects we need a visual system. We can say
that the color has an important role for our survival (for example: some living beings such as
some birds that have some colors in their plumage that is very important to them). Is a
physical and expressive and symbolic phenomenon of most importance in visual
language.Sometimes it can be a subjective concept that is based on the interpretation that
sensorial system and the brain give to the different lengths of light received.
Seeing is for us, such a natural phenomenom that is becomes necessary an effort of
imagination so that we can realize that such phenomenom includes the solution of certain
problems. The eyes are one of the most important organs of human body, they are
responsible for the capture of outside information and it‟s encoding, in nervous impulses
through the actions of specialized nervous cells. It‟s a fantastic and rather complex organ,
considered an extension of brain tissue. Until the 16th century, was wrongly thought that the
eyes produced light, today we know that they are only light receivers.
With this work is intended to describe in short words how the human being can see and

Full textAbstract:
As we move steadily through the multicore era, and the number of processing cores on each chip continues to rise, parallel computation becomes increasingly important. However, parallelising an application is often difficult because of dependencies between different regions of code which require cores to communicate. Communication is usually slow compared to computation, and so restricts the opportunities for profitable parallelisation. In this work, I explore the opportunities provided when communication between cores has a very low latency and low energy cost. I observe that there are many different ways in which multiple cores can be used to execute a program, allowing more parallelism to be exploited in more situations, and also providing energy savings in some cases. Individual cores can be made very simple and efficient because they do not need to exploit parallelism internally. The communication patterns between cores can be updated frequently to reflect the parallelism available at the time, allowing better utilisation than specialised hardware which is used infrequently. In this dissertation I introduce Loki: a homogeneous, tiled architecture made up of many simple, tightly-coupled cores. I demonstrate the benefits in both performance and energy consumption which can be achieved with this arrangement and observe that it is also likely to have lower design and validation costs and be easier to optimise. I then determine exactly where the performance bottlenecks of the design are, and where the energy is consumed, and look into some more-advanced optimisations which can make parallelism even more profitable.

Full textAbstract:
In this thesis I re-analyse the SCUBA archive data for the L1688 main cloud of Ophiuchus, incorporating all available scan-map and jiggle-map data. I create a new core mass function (CMF) for L1688 using updated values for the distance to this region, as well as new estimates for the temperatures and masses of the cores. I show that the CMF for LI688 is consistent with a three part power-law, with slopes the same as those seen in the stellar IMF. The deeper maps allows the discovery of a turnover in the CMF at 0.7A/, which shows that the core mass function appears to mimic the stellar initial mass function. This concordance is indicative that the stellar IMF is determined at the prestellar core phase. I also present HCO* (J=4 > 3) spectral line observations from HARP on the JCMT. Data are presented for 59 of the prestellar cores mapped using SCUBA. Using these data. I present a proposed evolutionary diagram for prestellar cores in the form of a radius-mass plot. I hypothesise that a core is formed in the low-mass, low-radius region of the plot. It then accretes quasi-statically, increasing in both mass and radius. When it crosses the limit of gravitational instability it begins to collapse, decreasing in radius, towards the region of the diagram where protostellar cores are seen. My predictions are borne out when I plot the collapsing cores on this diagram. I outline an analytical model, created by Whitworth & Ward-Thompson (2001), describing the collapse of a starless core with a Plummer-like density profile. I describe my addition of a simple radiative transfer code, which allows simulated spectral line profiles to be created for such cores. The model is shown to be consistent with previous models, and with the observed physical properties of prestellar cores. This model is applied to 20 of the spectral line profiles from the HCO+ (J=4 + 3) data. These 20 modelled cores are placed onto the proposed evolutionary diagram. Their modelled physical states are found to be consistent with the proposed evolutionary track. In conjunction with the SCUBA and HARP data, these fits allow a potential timeline for the LI688 cloud to be established for the first time.

No. of bitstreams: 0<br>A maricultura como atividade econômica começou a ser explorada no Estado de Santa Catarina em 1989, e vem crescendo progressivamente, sendo o Estado o maior produtor do país. O crescimento da maricultura reflete o sucesso da atividade como alternativa de desenvolvimento e geração de recursos para as comunidades de pescadores artesanais, além de contribuir, para conter a degradação progressiva dos ecossistemas litorâneos. Todavia, diversos problemas surgem com o aumento da produção e demanda no mercado consumidor. Poucos estudos existem sobre o impacto ambiental causado pela produção intensiva de mexilhões e ostras e sob o ponto de vista sanitário, um dos maiores problemas que afetam os cultivos e bancos naturais, é a contaminação do produto por toxinas produzidas pelas algas marinhas que compõem o fitoplâncton. No Brasil, não há estudos epidemiológicos relacionados às intoxicações em seres humanos. As doenças causadas pela ingestão são reportadas eventualmente, porém não há estimativas do número de casos. Com a expansão da maricultura, as florações de algas tóxicas, as chamadas 'Marés vermelhas", fenômeno ligado ao crescimento exacerbado de microalgas produtoras de toxinas se tornou um grande problema ambiental, econômico e de saúde pública em diversas regiões do planeta. Algumas toxinas provocam lesões cutâneas, perturbações digestivas, respiratórias ou nervosas. Apesar do amplo conhecimento científico e dos avanços da clínica e terapêutica, o controle das intoxicações por mariscos ainda se constitui em um desafio; porém não há como ignorar os determinantes sociais e culturais da endemia, assim como os conhecimentos e as necessidades das populações atingidas. Neste estudo, meu objetivo foi estudar as doenças causadas por toxinas marinhas interagindo com o conhecimento da sociedade - as concepções, normas e práticas retidas pela população. Minha preocupação era conhecer, através dos relatos a interpretação que as pessoas davam sobre as doenças causadas pela ingestão dos moluscos contaminados por toxinas marinhas e, mais particularmente, da origem destas, bem como do tratamento que lhes era imposto ou de como eles próprios viam ou praticavam o tratamento. A maioria dos entrevistados conhecia detalhes das doenças e verifiquei a existência de um imaginário coletivo muito bem estruturado, elaborado com base nas experiências vividas ou conhecidas. A etiologia das intoxicações revelou-se desconhecida, mas a expressão maré vermelha está sacramentada, porém sua associação com o quadro clínico não ficou clara. O conhecimento de que mariscos e ostras podem fazer mal, está estabelecido e aceito; porém fortemente influenciado pelo discurso e práticas médicas vigentes. Associa-se ao manuseio do alimento, cozimento e conservação inadequados. Muitas explicações foram apresentadas para justificar os sintomas decorrentes da ingestão de moluscos: No entanto, foi interessante perceber que todos têm consciência do risco, inclusive a nível coletivo. A maior parte dos sintomas descritos, com atribuição de causalidade às intoxicações por mexilhões e ostras, pode ser generalizada para várias outras doenças. Os sintomas gastrintestinais foram os mais citados, incluindo diarréias, náuseas e vômitos, cólicas, azias, dispepsias, além de vertigens e febre. E outra observação interessante, é que quaisquer que sejam os fatores etiológicos e terapêuticos, em parte estão culturalmente determinados. A resultante é a crescente popularidade das práticas ditas alternativas, principalmente os chás de ervas, tidos como infalíveis. A maioria das pessoas, não buscou recurso médico, quando acometidas por distúrbios relacionados à ingestão de frutos do mar. Durante um problema de saúde, percebe-se que a própria família é o primeiro e às vezes único recurso a ser procurado, especialmente nas figuras dos membros mais experientes. Nenhum dos entrevistados conseguiu descrever o complexo ciclo das intoxicações e todas mediações entre o meio ambiente e os seres humanos.

Previous issue date: 1995<br>Resumo: Ao iniciarmos o desenvolvimento deste trabalho enfocando a fenomenologia da cor, procuramos estabelecer condições para o entendimento correto das particularidades que nos levam a diferenciar a reflexão da luz, suas alterações em relação ao ambiente, objetos e , a utilização dos conhecimentos científicos, a evolução da tecnologia, aplicados às diferentes necessidades de representação e expressão através de variações cromáticas. As classificações que se sucederam através dos séculos, suas concordâncias e contradições, apresentam-se como caminho para a compreensão
dos diferentes sistemas de representação cromática. À classificação equivocada do vermelho, como cor primária do
sistema subtrativo, procuramos contrapor o que é aceito por autores e pesquisadores contemporâneos, e evidenciar algumas dúvidas admitidas 'por aqueles que primeiro se ocuparam dessa busca entusiasmadora. Além do vermelho, as outras cores do espectro apresentam-se para nossa análise e considerações. Com o objetivo de contribuir para dirimir dúvidas, tanto no ensino da classificação de cores nos cursos de primeiro e segundo graus, como nas discussões articuladas nos cursos universitários que se ocupam do assunto, empreendemos a produção do material ilustrativo que acompanha este texto. Nossa atenção firmou-se, sempre, na relação cor-luz, corpigmento, entendendo que um sistema não exclui o outro, pelo contrário, confirmam-se<br>Abstract: The present thesis focuses on the phenomenon of color. lnitially,an attempt is made to establish conditions for the comprehension of those peculiarities which lead to the need for a distinction between the actual reflection of light and the alterations in such reflection brought about by specific objects or environments. Scientific and technological advances in chromatology have also been explored in relation to the necd for representation and expression of chromatic variation. The similarities and differences involved in the classification of color which have come down to us through the centuries suggest how different systems of chromatic representation can be understood. Special emphasis is given here to the contrast between the traditional, yet erroneous, classification of red, a primary color in the subtractive system, and that which is general1y accepted by professional chromatologists today, and various problems perceived by such researchers are investigated. The other colors of the spectrum, however, are also investigated and analyzed. ln an attempt to clarify the situation for the teaching of the classification of color in elementary and secondary art classes, as well as for discussions conducted in university courses where color is of primary importance, we have produced illustrative material and have reproduced it here. The emphasis on the relation between colorllight and
colori pigment is maintained throughout, since it is understood that these are complementary aspects, rather than mutually exclusive concepts<br>Mestrado<br>Mestre em Artes

Full textAbstract:
The neuronal mechanisms of parametric working memory – the short-term storage of graded stimuli to guide behavior – are not fully elucidated. We have designed a working memory task where rats compare two sequential vibrations, S1 and S2, delivered to their whiskers (Fassihi et al, 2014). Vibrations are a series of velocities sampled from a zero-mean normal distribution. Rats must judge which stimulus had greater velocity standard deviation, σ (e.g. σ1 > σ2 turn left, σ1 < σ2 turn right). A critical operation in this task is to hold S1 information in working memory for subsequent comparison. In an earlier work we uncovered this cognitive capacity in rats (Fassihi et al, 2014), an ability previously ascribed only to primates. Where in the brain is such a memory kept and what is the nature of its representation?
To address these questions, we performed simultaneous multi-electrode recordings from barrel cortex – the entryway of whisker sensory information into neocortex – and prelimbic area of medial prefrontal cortex (mPFC) which is involved in higher order cognitive functioning in rodents. During the presentation of S1 and S2, a majority of neurons in barrel cortex encoded the ongoing stimulus by monotonically modulating their firing rate as a function of σ; i.e. 42% increased and 11% decreased their firing rate for progressively larger σ values. During the 2 second delay interval between the two stimuli, neuronal populations in barrel cortex kept a graded representation of S1 in their firing rate; 30% at early delay and 15% at the end. In mPFC, neurons expressed divers coding characteristics yet more than one-fourth of them varied their discharge rate according to the ongoing stimulus. Interestingly, a similar proportion carried the stimulus signal up to early parts of delay period. A smaller but considerable proportion (10%) kept the memory until the end of delay interval.
We implemented novel information theoretic measures to quantify the stimulus and decision signals in neuronal responses in different stages of the task. By these measures, a decision signal was present in barrel cortex neurons during the S2 period and during the post stimulus delay, when the animal needed to postpone its action. Medial PFC units also represented animal choice, but later in the trial in comparison to barrel cortex. Decision signals started to build up in this area after the termination of S2.
We implemented a regularized linear discriminant algorithm (RDA) to decode stimulus and decision signals in the population activity of barrel cortex and mPFC neurons. The RDA outperformed individual clusters and the standard linear discriminant analysis (LDA). The stimulus and animal’s decision could be extracted from population activity simply by linearly weighting the responses of neuronal clusters. The population signal was present even in epochs of trial where no single cluster was informative.
We predicted that coherent oscillations between brain areas might optimize the flow of information within the networks engaged by this task. Therefore, we quantified the phase synchronization of local field potentials in barrel cortex and mPFC. The two signals were coherent at theta range during S1 and S2 and, interestingly, prior to S1. We interpret the pre-stimulus coherence as reflecting top-down preparatory and expectation mechanisms.
We showed, for the first time to our knowledge, the neuronal correlates of parametric working memory in rodents. The existence of both positive and negative codes in barrel cortex, besides the representation of stimulus memory and decision signals suggests that multiple functions might be folded into single modules. The mPFC also appears to be part of parametric working memory and decision making network in rats.

Full textAbstract:
The work presented in this thesis is a continuation of a master?s thesis research project conducted by the author to gain insight into the applicability of inverse methods to developing adaptive simulation capabilities for core physics problems. Use of adaptive simulation is intended to improve the fidelity and robustness of important core attributes predictions such as core power distribution, thermal margins and core reactivity. Adaptive simulation utilizes a selected set of past and current reactor measurements of reactor observables to adapt the simulation in a meaningful way that is reflected in higher fidelity and robustness of the adapted core simulators models. We propose an inverse theory approach in which the multitudes of input data to core simulators, i.e. reactor physics and thermal-hydraulic data, are to be adjusted to improve agreement with measured observables while keeping core simulators models unadapted. At a first glance, devising such adaption for typical core simulators models would render the approach impractical. This follows, since core simulators are based on very demanding computational models, i.e. based on complex physics models with millions of input data and output observables. This would spawn not only several prohibitive challenges but also numerous disparaging concerns. The challenges include the computational burdens of the sensitivity-type calculations required to construct Jacobian operators for the core simulators models. Also, the computational burdens of the uncertainty-type calculations required to estimate the uncertainty information of core simulators input data presents a demanding challenge. The concerns however are mainly related to the reliability of the adjusted input data. We demonstrate that the power of our proposed approach is mainly driven by taking advantage of this unfavorable situation and show that significant reductions in both computational and storage burdens can be attained for a typical BWR core simulator adaption problem without compromising the quality of the adaption.

Tesis para optar al grado de Magíster en Administración<br>Autores no autorizan el acceso a texto completo de su documento<br>El aumento de la esperanza de vida, ha hecho que el cuidado o supervisión de los adultos mayores sean una de las principales tareas que se deben gestionar en el núcleo familiar, ya que en ocasiones requieren cuidados especiales y suelen ser demandantes en forma progresiva en la medida que avanza la edad. Muchas veces los hijos o familiares cercanos no están preparados o tienen la capacidad y conocimientos para cuidarlos de la mejor manera, por lo tanto es necesario un apoyo adicional que asegure el correcto cuidado y bienestar de los adultos mayores junto a sus familias. Por eso hemos decidido crear Geriatry Home Care una empresa especialista en el cuidado del adulto mayor en domicilios brindando seguridad, confianza y profesionalismo a las familias para el cuidado del paciente, quien será atendido a través de un equipo de profesionales especialistas en cuidado de ancianos.
Nuestra propuesta de Valor es ofrecer a la comunidad un servicio de cuidado domiciliario integral de ancianos, con los más altos estándares de calidad y calidez, brindando asistencia permanente a nuestros pacientes y familiares en su propio hogar.
Nuestros clientes son familiares de adultos mayores pertenecientes al GSE ABC1 que requieren asistencia en el cuidado del adulto mayor perteneciente a su núcleo familiar en su hogar. Nuestros usuarios son los adultos mayores cuyos familiares pertenecen al grupo objetivo antes descrito.
Los adultos mayores representan el 16.7% de la población en Chile, y están creciendo a razón de 3.5% al año, y se espera que al año 2015 el 20% de la población tenga más de 60 años. El 10% de los adultos mayores en Chile pertenecen al GSE más altos, quienes tienen el poder adquisitivo mayor, y tienen mayor disposición a pagar por productos y servicios de alta calidad.
Si bien actualmente existen algunas empresas dedicadas al cuidado domiciliario, todas ellas son básicamente empresas de hospitalización domiciliaria en general, que últimamente están desarrollando el negocio de cuidado de adultos mayores. También existe oferta de cuidado por parte de auxiliares quienes prestan el servicio en forma informal y desorganizada, que se dan a conocer a través de la recomendación proveniente de los mismos usuarios entre conocidos, y son muy demandadas, incluso escasas, pero no cuentan con la supervisión de profesionales en el servicio entregado. Lo anterior hace que exista una porción importante del mercado no atendido y otra que podría recibir una mejor oferta de servicio.
Nuestra oferta consta en ofrecer un servicio integral de cuidado del adulto mayor en el hogar, incluyendo estimulación, recreación, alimentación, medicación, limpieza y confort del paciente, otorgando a él y a su entorno calidad de vida. Algunos de los servicios ofrecidos serán:
Cuidado paciente no crítico: paciente valente que no requiere hospitalización domiciliaria.
Cuidado de paciente crítico: paciente no valente que requiere hospitalización domiciliaria.
Queremos “Ser los principales cuidadores de adultos mayores a domicilio en la región metropolitana de Santiago. Distinguiéndonos por la excelencia en el servicio que prestamos, la vocación de servicio y la solidez operacional”.
La inversión inicial considerada para el proyecto es de $170,000,000.
Considerando la evaluación financiera, podemos ver que es un negocio rentable y atractivo, dadas las condiciones de la industria, la baja penetración del mercado, el bajo nivel de riesgo y los flujos futuros estimados. Es importante considerar además la estructura de costos de la compañía, ya que el ser una empresa de servicios da un atractivo especial al negocio, ajustar el tamaño no es complejo, ya que tiene una estructura de costos flexibles. El apalancamiento operativo es bajo, un aumento en las ventas produce una variación en mayor proporción en los beneficios y viceversa, por lo tanto la empresa tiene un nivel de riesgo operacional menor, ya que no es complejo cubrir los costos fijos.

This statement gives an overall summary of the aims and achievements of the research work and scholarship carried out by the author during her time at The University of Manchester (and UMIST - now part of The University of Manchester) for which the publications presented give evidence. The research has been about exploring the design process, the activities and issues, and elements involved - from both an industry and student point of view. The publications explore design pedagogy, the skills required by designers and how these might fit into a curriculum for design today.In three parts it summarises the publications presented, reviews the main aspects of design and the current state of knowledge and research in design and summarises the core aspects as distilled from over 36 years practice, research and scholarship.The driver for much of the research undertaken has been to gain a better understanding of the core aspects of design - what key knowledge and skills are required by designers to allow the consistent design of better products and services which enhance the experiences of users. The work presented investigates design and design methods: the activities and processes and the elements involved. It considers responses to designs, the emotional aspect of design - why some designs are preferred over others, why some colour combinations are more desirable, and why repetition is so important to the human psyche. Underpinning the work presented are three research questions. • Are design rules and processes generic for whatever is being designed? • Can a better understanding of design theory and the emotional response to designs ensure a more effective process and thus lead to stronger designs? • Can students be educated to be better design thinkers and ultimately better designers? It concludes that: • 'design' is a process; • design is a problem-solving process and problem-solving is a design process; • for the most effective outcomes a creative and structured approach is required; • this process is based on generic rules and principles which are applicable across all discipline areas; • collaborative/cross disciplinary elements reinforce the concept that there are processes involved that are not unique to individuals or discipline specific; • a greater understanding of the process is of benefit to all individuals and organisations; • any design/problem solving activity will normally result in more than one solution option. The results of the research have informed the author's teaching practice and have been disseminated through publications to benefit the wider education arena. The work presented aims to inform students and design education practitioners.

Full textAbstract:
This diploma thesis deals with the topic of core banking systems. The main objective is to analyze the implementation of the SEPA payments into the payment module. The theoretical part defines the concept of core banking systems and its history. It also compares conventional approaches to core banking systems with Islamic ones. The theoretical part also includes chapters about implementation approaches, the most common challenges in implementation and architecture of core banking systems. Next part of thesis is about the basic modules of core banking systems. The practical part is about the analysis of requirements on core banking systems. Especially the requirements that are mandatory from legislation perspective. These are SEPA payments, PSD2 and instant payments. Gap analysis is used as the main method. We chose SEPA payment implemetation as the requirement that we will analyse. There are two possible solutions that can be used. The first one is the customization of the current payment module and the second solution is implementation of the payment hub. The conclusion of the thesis focuses on the best solution for each of two types of bank institutions. The main acquisition of the thesis is the recommended solution for two different types of banks. And second of all, the conclusions which was founded in this thesis should be used for another requirements such as PSD2, the introduction of instant payments, and more.

A literature review indicates that prefrontal-frontal regions seem to have a predominant role in different aspects of time-related processing. But posterior regions appear to interact with them, although its exact nature remains to be determined. Our work concerns more especially dynamic interactions in the anterio-posterior dimension during duration discriminations. Event related potentials (ERPs) permit investigations of the role of neocortical areas in different processing stages associated with behavioral performances. Our two main objectives were to analyze the nature of neocortical interactions in temporal information processing as well as identifying ERPs involved in selective processing stages. To reach these objectives, two studies were initiated in normal human subjects

Full textAbstract:
The sensorimotor network receives a rich variety of somesthetic afferents and outputs considerable motor efferents, both of which drive experience-dependent plasticity in the system. It remains unclear to what extent subtle changes in somaesthesis and motor function extrinsic to the brain drive plasticity in the functional organisation and anatomy of the sensorimotor network. This thesis contains a series of multimodal MRI experiments to investigate how altered-use and disuse can induce plastic changes in the sensorimotor network of the human brain. In Chapter 3, a method of mapping digit somatotopy in primary somatosensory cortex at the single-subject level using 7.0 tesla fMRI was developed and applied for a study of healthy participants. Using a phase-encoding paradigm, digit representations were accurately mapped in under 10 minutes. These maps were reproducible over time and comparable to a standard block design. In Chapter 4, a further fMRI study assessed the potential for short-term reorganisation of digit representations in primary somatosensory cortex following a manipulation whereby the right index and right middle fingers were glued together for 24 hours. There was a marked shift in the cortical overlap of adjacent digits after the glued manipulation, not seen across an equivalent control period, providing strong evidence for short-term remapping of primary somatosensory cortex. In Chapter 5, a patient study investigated plasticity associated with chronic unilateral disuse of the upper limb. A cross-sectional comparison with control participants showed reduced grey matter density in the posterior right temporoparietal junction, and increased radial diffusivity in the white matter of the right superior longitudinal fasciculus, consistent with change in the right ventral attention network. A complementary longitudinal study in Chapter 6 investigated structural plasticity associated with rehabilitation of the disused limb. There were localised increases in grey matter density, notably in the right temporoparietal junction, further implicating a potential role for regions responsible for egocentric attention in regaining upper limb use. In Chapter 7, a further patient study investigated candidate predictive biomarkers at the sub-acute stage of stroke recovery, identifying CST-lesion cross-section and sensorimotor network strength as correlates of motor function, which warrant further study. The results of the studies presented in this thesis provide a novel insight into the nature and time frame of functional and structural plasticity associated with altered use and disuse. Further study of how subtle changes in our sensory and motor use shape the sensorimotor network is warranted, particularly in the context of disuse in non-neurological clinical populations.

Actuellement, la majorité des architectures de processeurs sont fondées sur une mémoire partagée avec cohérence de caches. Des prototypes intégrant de grandes quantités de cœurs, reliés par une infrastructure de transmission de messages, indiquent que, dans un proche avenir, les architectures de processeurs vont probablement avoir ces caractéristiques. Ces deux tendances exigent que les processus s'exécutent en parallèle et rendent la programmation concurrente nécessaire. Cependant, la difficulté inhérente du raisonnement sur la concurrence peut rendre ces nouvelles machines difficiles à programmer. Nous explorons trois approches ayant pour but de faciliter la programmation concurrente. Nous proposons WFR-TM, une approche fondé sur la mémoire transactionnelle (TM), un paradigme de programmation concurrente qui utilise des transactions afin de synchroniser l'accès aux données partagées. Une transaction peut soit terminer (commit), rendant visibles ses modifications, soit échouer (abort), annulant toutes ses modifications. WFR-TM tente de combiner des caractéristiques désirables des TM optimistes et pessimistes. Une TM pessimiste n'échoue jamais aucune transaction; néanmoins les algorithmes existants utilisent des verrous pour exécuter de manière séquentielle les transactions qui contiennent des opérations d'écriture. Les algorithmes TM optimistes exécutent toutes les transactions en parallèle mais les terminent seulement si elles n'ont pas rencontré de conflit au cours de leur exécution. WFR-TM fournit des transactions en lecture seule qui sont wait-free, sans jamais exécuter d'opérations de synchronisation coûteuse (par ex. CAS, LL\SC, etc) ou sacrifier le parallélisme entre les transactions d'écriture. Nous présentons également Dense, une implémentation concurrente de graphe. Les graphes sont des structures de données polyvalentes qui permettent la mise en oeuvre d'une variété d'applications. Cependant, des applications multi-processus qui utilisent des graphes utilisent encore largement des versions séquentielles. Nous introduisons un nouveau modèle de graphes concurrents, permettant l'ajout ou la suppression de n'importe quel arc du graphe, ainsi que la traversée atomique d'une partie (ou de l'intégralité) du graphe. Dense offre la possibilité d'effectuer un snapshot partiel d'un sous-ensemble du graphe défini dynamiquement. Enfin, nous ciblons les futures architectures. Dans l'intérêt de la réutilisation du code il existe depuis quelques temps une tentative d'adaptation des environnements d'exécution de logiciel - comme par ex. JVM, l'environnement d'exécution de Java - initialement prévus pour mémoire partagée, à des machines sans cohérence de caches. Nous étudions des techniques générales pour implémenter des structures de données distribuées en supposant qu'elles vont être utilisées sur des architectures many-core, qui n'offrent qu'une cohérence partielle de caches, voir pas de cohérence du tout<br>Though a majority of current processor architectures relies on shared, cache-coherent memory, current prototypes that integrate large amounts of cores, connected through a message-passing substrate, indicate that architectures of the near future may have these characteristics. Either of those tendencies requires that processes execute in parallel, making concurrent programming a necessary tool. The inherent difficulty of reasoning about concurrency, however, may make the new processor architectures hard to program. In order to deal with issues such as this, we explore approaches for providing ease of programmability. We propose WFR-TM, an approach based on transactional memory (TM), which is a concurrent programming paradigm that employs transactions in order to synchronize the access to shared data. A transaction may either commit, making its updates visible, or abort, discarding its updates. WFR-TM combines desirable characteristics of pessimistic and optimistic TM. In a pessimistic TM, no transaction ever aborts; however, in order to achieve that, existing TM algorithms employ locks in order to execute update transactions sequentially, decreasing the degree of achieved parallelism. Optimistic TMs execute all transactions concurrently but commit them only if they have encountered no conflict during their execution. WFR-TM provides read-only transactions that are wait-free, without ever executing expensive synchronization operations (like CAS, LL/SC, etc), or sacrificing the parallelism between update transactions. We further present Dense, a concurrent graph implementation. Graphs are versatile data structures that allow the implementation of a variety of applications. However, multi-process applications that rely on graphs still largely use a sequential implementation. We introduce an innovative concurrent graph model that provides addition and removal of any edge of the graph, as well as atomic traversals of a part (or the entirety) of the graph. Dense achieves wait-freedom by relying on light-weight helping and provides the inbuilt capability of performing a partial snapshot on a dynamically determined subset of the graph. We finally aim at predicted future architectures. In the interest of ode reuse and of a common paradigm, there is recent momentum towards porting software runtime environments, originally intended for shared-memory settings, onto non-cache-coherent machines. JVM, the runtime environment of the high-productivity language Java, is a notable example. Concurrent data structure implementations are important components of the libraries that environments like these incorporate. With the goal of contributing to this effort, we study general techniques for implementing distributed data structures assuming they have to run on many-core architectures that offer either partially cache-coherent memory or no cache coherence at all and present implementations of stacks, queues, and lists
