Vinna eller försvinna! : En studie av afghanska arméns krigföringsförmåga

Camél, Adam January 2012 (has links)
I samband med att Afghanistan själva skall ta över säkerhetsansvaret i landet från 2015 kommer en stor del av framgången bero på den afghanska arméns (ANA) förmåga och färdigheter. Avseende dess kapacitet att klara av denna uppgift har det framförts tvivel. Mot bakgrund av detta kommer den afghanska arméns krigföringsförmåga i nutid att undersökas i denna uppsats i syfte att kartlägga eventuella förtjänster samt brister som i sin tur kanske kan ge en fingervisning om framtiden.   Metoden utgörs av en fallstudie av (ANA) där ett analysverktyg skapas med hjälp av J.F.C Fullers teorier om krigföringsförmåga han framför i sin bok ”The Foundations of the Science of War” och specifikt det han benämner som the threefold order. Krigföringsförmågan delas i sin tur in i fysiska, konceptuella och moraliska faktorer.   Med hjälp av detta analysverktyg sorterar jag undersökningsmaterialet, som framförallt utgörs av rapporter från det amerikanska försvarsdepartementet och kongressen, med hjälp av kvalitativ textanalys.   Avslutningsvis besvaras den övergripande frågeställningen genom en analys av det insamlade undersökningsmaterialet och en avslutande diskussion.   Det övergripande resultatet är att ANA har gjort stora framsteg under de senaste åren men att den samlade krigföringsförmågan bedöms som låg. Inom de fysiska faktorerna är det framförallt den låga krigsdugligheten bland fältförbanden samt inom flygvapnet och stödfunktionerna som drar ner betyget. Inom de konceptuella är det bristen på utbildare, den svaga rekryteringen och utbildningen av underofficerare och olika traditioner inom officerskåren. Det som är sämst är de moraliska faktorerna där framförallt etniska problem och nepotism bidrar till splittring inom armén.

Desempenho de leitões submetidos a diferentes densidades durante a fase de creche / Performance of pigs submitted to differents stocking densities during the nursery phase

Marimon, Bruno Teixeira January 2018 (has links)
O objetivo deste estudo foi avaliar o efeito da densidade sobre o desempenho e o comportamento de leitões na fase de creche. Um total de 560 leitões desmamados (peso médio de 5,75 ± 0,9 kg e idade média de 20,92 ± 0,8 dias) foram aleatoriamente alojados em quatro tratamentos com diferentes densidades: T0,33, T0,28, T0,23 e T0,18 (0,33, 0,28, 0,23 e 0,18 m²/animal respectivamente). As baias continham 20 animais e a ração foi fornecida à vontade. As lesões de cauda e orelha foram graduadas em escores de 0 a 4 e o número de lesões de briga foram avaliados semanalmente. Dezesseis baias foram filmadas em três momentos (1ª, 4ª e 6ª semana de alojamento) para avaliação da frequência de brigas e de belly nosing. Foi observado um efeito linear da densidade sobre o ganho de peso diário (GPD; P=0,049), um efeito quadrático sobre o peso aos 42 dias (P=0,030) e uma tendência de efeito quadrático para o consumo médio diário (CMD; P=0,075). Não houve efeito da densidade na conversão alimentar (CA) e no coeficiente de variação (CV) do peso aos 42 dias. Foi observado um maior número de leitões apresentando lesões severas de orelha no grupo T0,18 quando comparado ao T0,33 (P = 0,019) e T0,28 (P = 0,056). Um maior número de animais com lesões moderadas ou severas foi observado no grupo T0,18 (P < 0,05) do que nos demais grupos para lesões de orelha, e do que T0,33 para lesões de cauda. Houve um efeito linear da densidade sobre a frequência de brigas, com uma maior ocorrência nos grupos com menos espaço. Contudo, não foi observado efeito sobre o número de lesões de briga ou de casos de belly nosing. Em conclusão, o aumento da densidade afetou negativamente o desempenho dos leitões, além de aumentar a ocorrência de comportamentos indesejáveis. / The aim of this study was to evaluate the effect of space allowance on performance and behavior of nursery pigs. At weaning 560 pigs (5.75 ± 0.9 kg of body weight and 20.92 ± 0.8 days of age) were randomly assigned in four treatments with different stocking densities: T0.33, T0.28, T0.23 and T0.18 (0.33, 0.28, 0.23 and 0.18 m²/pig respectively). Pens were standardized to have the same group size (20 pigs/pen) and feed was provided ad libitum. Tail and ear biting lesions and the fighting lesions were weekly observed. Sixteen pens were videotaped in three different moments (1st, 4th and 6th housing week) and the frequency of fights and belly nosing were recorded. A linear effect was observed of stocking density on average daily gain (ADG; P=0.049), a quadratic effect and a quadratic tendency of effect were observed on body weight at 42 days after weaning and on average daily feed intake (ADFI) (P=0.030; P=0.075, respectively). There was no effect of stocking density on the gain:feed ratio or weight coefficient of variation (CV) at day 42. Higher graduation of severe ear lesions was observed in pigs from T0.18 when compared to T0.33 (P = 0.0196) and T0.28 (P = 0.056). A higher number of pigs with moderate or severe tail and ear lesions was observed in T0.18 (P > 0.05). Moreover, it was observed a linear effect of density on the frequency of fights, with higher occurrence in groups housed in restricted spaces. However, no effect of stocking density was observed on fight lesions or belly nosing among treatments. In conclusion, increased density negatively affected the performance of piglets and increased the occurrence of unsuitable behaviors.

Multi-fragment visibility determination in the context of order-independent transparency rendering / Determinação de visibilidade de efeitos multi-fragmentos no contexto de transparência independente de ordem

Maule, Marilena January 2015 (has links)
No contexto de imagens geradas por computador, efeitos multi-fragmento são aqueles que determinam a cor do pixel baseados em informações computadas a partir de mais de um fragmento. Nesse tipo de efeito, a contribuição de cada fragmento é extraída de sua visibilidade com respeito a um determinado ponto de vista. Observando uma sequencia de fragmentos vista através de um pixel, a visibilidade de um fragmento depende da sua relação espacial com os demais fragmentos. Essa relação pode ser reduzida ao problema de ordenação de múltiplos fragmentos. Portanto, ordenação é essencial para correta avaliação de efeitos multi-fragmento. A pesquisa desta tese foca em dois problemas multi-fragmento clássicos: transparência independente de ordem e anti-aliasing de fragmentos transparentes. Enquanto o efeito de transparência necessita de ordenação de fragmentos ao longo do raio de visualização do pixel, anti-aliasing aumenta a complexidade do problema ao adicionar informação espacial do fragmento com respeito à área do pixel. A contribuição desta tese é o desenvolvimento de uma solução para visibilidade de fragmentos que pode tirar proveito do pipeline de transformação e iluminação, implementando nas GPUs de hoje. Nós descrevemos ambos os problemas de transparência e anti-aliasing, discutindo soluções anteriores, além de classificá-las e compará-las. Nossa análise associa soluções a implementações específicas, comparando uso de memória, desempenho e qualidade de imagem. Os documentos resultantes fornecem uma visão geral das áreas abordadas, contendo: qual é o estado-da-arte atualmente, o que ele é capaz de fazer e quais são suas limitações, ou seja, onde melhorias são possíveis. Como parte integrante desta tese, nós propomos duas novas técnicas para processar transparência independente de ordem. Nós mostramos como obter o menor consumo de memória para cálculo exato de transparência, em um número finito de passos de geometria; permitindo aumento da complexidade das cenas representadas e da resolução da imagem final, em relação aos métodos anteriores, dada uma determinada configuração de hardware. Adicionalmente, demonstramos que, para a maior parte dos casos, os fragmentos mais próximos ao observador tem maior impacto sobre a cor final do pixel. Também mostramos como esta perspectiva sobre o problema inspirou novas técnicas. A pesquisa também inclui a investigação de uma nova abordagem para anti-aliasing para fragmentos transparentes. Através do uso de uma única amostra por fragmento, nosso objetivo é reduzir o consumo de memória enquanto melhoramos desempenho e qualidade. Experimentos preliminares apresentam resultados promissores em comparação com a técnica mais usada para anti-aliasing. / Multi-fragment effects, in the computer-generated imagery context, are effects that determine pixel color based on information computed from more than one fragment. In such effects, the contribution of each fragment is extracted from its visibility with respect to a point of view. Seen through a pixel’s point of view, the visibility of one fragment depends on its spatial relationship with other fragments. This relationship can be reduced to the problem of sorting multiple fragments. Therefore, sorting is the key to multi-fragment evaluation. The research on this dissertation is focused on two classical multi-fragment effects: order-independent transparency and anti-aliasing of transparent fragments. While transparency rendering requires sorting of fragments along the view ray of a pixel, anti-aliasing increases the problem complexity by adding spatial information of fragments with respect to the pixel area. This dissertation contribution relies on the work towards the development of a solution for the visibility of fragments that can take advantage of the transformation and lighting pipeline implemented in current GPUs. We describe both transparency and aliasing problems, for which we discuss existing solutions, analyzing, classifying and comparing them. The analysis associates solutions to specific applications, comparing memory usage, performance, and quality. The result is a general view of each field: which are the current state-of-the-art capabilities and in which direction significant improvements can be made. As part of this dissertation, we proposed two novel techniques for order-independent transparency rendering. We show how to achieve the minimum memory footprint for computing exact transparency in a bounded number of geometry passes; allowing increasing scene complexity and image resolution to be feasible within current hardware capabilities. Additionally, we demonstrate that, for most scenarios, the front-most fragments have the greatest impact on the pixel color. We also show how the perspective we propose has inspired recent transparency techniques. The research includes the investigation of a novel anti-aliasing approach for transparent fragments. Through the use of a single sample per fragment, we aim at reducing memory footprint while improving performance and quality. Preliminary experiments show promising results, in comparison with a well established and largely used anti-aliasing technique.

Songbased rival assessment in songbirds / Songbased rival assessment in songbirds

LINHART, Pavel January 2014 (has links)
This study shows the importance of the basic spectro-temporal song parameters in territorial contests between male songbirds. Chiffchaff and willow warbler were selected as model species for their phylogenetic and ecological similarity, strong territorial behaviour, but very different singing styles. We found that bigger males of both species sing lower pitched songs and that males of both species adjust their behaviour according to song pitch of their rival simulated by playback. Thus, it seems that both species use song pitch to acoustically assess the body size of their rivals. We also show that song length and syllable rate are important features of the song, probably signalling short-term motivation to escalate territorial conflict.

Ballistic impact on composite armour

Bourke, P. January 2007 (has links)
Armoured vehicles in current military service are requiring ever more protection to enable them to carry out their mission in a safe, effective manner. This requirement is driving vehicle weight up to such an extent that the logistics of vehicle transport is becoming increasingly difficult. Composite materials are an important material group whose high specific properties can enable structures to be manufactured for a far lower weight than might otherwise be possible. Composite materials in an armoured vehicle will require structural performance as well as ballistic performance. The mechanical and ballistic performance of tl-kk armour and structural composites has been investigated against dcformable and armour-piercing ammunitions, over a range of impact velocities. Testing has indicated that heavy/coarse reinforcement weaves perform well against deformable ammunition and light/fine weaves well against armour piercing ammunition. The effect of individual mechanical properties on ballistic performance has been investigated as has the damage morphology of impacted materials. High tensile strength combined with low fracture toughness has been identified as an important requirement. Failure mechanisms have been identified from sections of ballistic impacts and through the use of mechanical test data the energy absorbed by each mechanism has been calculated. An energy audit has been carried out of all materials tested and a modelling procedure developed based on mechanical characteristics, damage morphology and failure mechanisms. This model has been tested against literature results and found to give very satisfactory performance.
