Marty, Simon. « Influence of social and ecological factors on the evolution of the olfactory system in Hymenoptera ». Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASL039.
Texte intégralAnimal lifestyles depend on a set of adaptive behaviours that rely on the accurate detection and processing of sensory information within neural circuits. The olfactory system, which perceives the chemical environment, has evolved under diverse selective pressure, diversifying its neural circuits. Hymenoptera represents an ideal order for studying the principles of sensory system adaptation, owing to their diverse lifestyles. From plant feeding to predation, and from diverse forms of parasitism to the repeated evolution of cooperative social structures, Hymenoptera provide numerous opportunities for comparative studies of neural trait evolution. Particularly, eusociality is an advanced form of social organisation, where individuals refrain from their own reproduction for the benefit of reproducing relatives. Due to the vulnerability of altruistic behaviour to exploitation, the evolution of eusociality is hypothesised to be intimately linked with the development of efficient recognition and communication systems. In insects, this recognition involves the perception of odorous compounds known as cuticular hydrocarbons (CHCs), facilitating the discrimination of social partners. In ants and hornets, the detection of CHCs is known to involve the basiconic sensilla subsystem (BaS), which represents a morphological division within the first olfactory processing centre of the brain, the antennal lobe (AL). Given that eusociality evolved independently from solitary ancestors in these two taxa, our investigation focuses on the origin and diversification of this sensory specialisation across solitary and social Hymenoptera, aiming to uncover the influence of social and ecological factors on the olfactory system. We first conducted a comparative study of neural traits within the olfactory system of fourteen ant species distributed across the Formicidae phylogeny. We found that the general organisation of the ant olfactory system is conserved across species, despite remarkable differences in neuropil volume and number of glomeruli. Although we did not identify clear behavioural, ecological, or social traits potentially shaping AL elaboration, our results identified the species-specific complexity of CHC blend composition as a potential driver of neural investment in the BaS subsystem. Then, concentrating on the Vespidae, in which eusociality emerged twice independently, we asked if the BaS subsystem could represent an adaptation driven by the social lifestyle or if it was a pre-existing attribute inherited from solitary ancestors. Based on extensive neuroanatomical data, we show that the solitary ancestors of social species were already equipped with an elaborated BaS subsystem. Moreover, we found divergent AL investment between the different eusocial subfamilies, while solitary species exhibited similar or even greater investment in AL glomeruli. These findings suggest that eusociality has probably not been a major driver of AL evolution. Finally, we investigated the evolutionary origins and elaboration of the BaS subsystem by carrying out a broad comparative neuroanatomical study of the AL across the Hymenoptera. Our data suggest that the BaS subsystem is conserved across most parasitoid and aculeate clades. However, it is remarkably reduced or even lost in bees, indicating that the overall AL organisation in Hymenoptera evolved under strong selection pressure associated with dietary behaviour, rather than the level of social organisation. These studies fill important gaps in our understanding of sensory evolution in Hymenoptera and provide valuable insights into the specific roles of ecological and social factors in driving sensory adaptation

Texte intégralThis work holds the purpose of presenting an auxiliary way of bone density measurement through the attenuation of electromagnetic waves. In order to do so, an arrangement of two microstrip antennas with rectangular configuration has been used, operating in a frequency of 2,49 GHz, and fed by a microstrip line on a substrate of fiberglass with permissiveness of 4.4 and height of 0,9 cm. Simulations were done with silica, bone meal, silica and gypsum blocks samples to prove the variation on the attenuation level of different combinations. Because of their good reproduction of the human beings anomaly aspects, samples of bovine bone were used. They were subjected to weighing, measurement and microwave radiation. The samples had their masses altered after mischaracterization and the process was repeated. The obtained data were inserted in a neural network and its training was proceeded with the best results gathered by correct classification on 100% of the samples. It comes to the conclusion that through only one non-ionizing wave in the 2,49 GHz zone it is possible to evaluate the attenuation level in the bone tissue, and that with the appliance of neural network fed with obtained characteristics in the experiment it is possible to classify a sample as having low or high bone density

Por fim, implementar o dispositivo criado nas sapatilhas e na bola, que irão ser utilizados no jogo de futsal. Foram realizadas várias simulações com módulos de desenvolvimento, de modo a atestar se o sistema projetado seria passível de ser implementado. Essas simulações correram tal como esperado, concluindo que os sistema é exequível. Aquando da conceção dos dispositivos do sistema, surgiram alguns problemas na realização das placas dos mesmos, e levaram a contratempos que fizeram com que estes não estivessem prontos a tempo de serem apresentados. Os resultados obtidos foram apenas os provenientes das simulações realizadas com os módulos de desenvolvimento, resultados esses que levam a crer que o sistema tem potencial para ser implementado num futuro próximo.
This dissertation consisted in the study of various technologies including RFID, in order to design a system that is capable of measuring the ball possession in a futsal game. This study focused on what type of RFID system to use, what are the advantages and disadvantages of each one and which are the best suited to perform the devices. Likewise, studying what is the best way of wireless communication and type of architecture, by presenting the advantages and disadvantages of each one. After choosing the technologies to be used, was begun the conception of the devices, by designing and conceiving boards that would form it. Finally, implementing the device in the sneakers and in the ball, that will be used in a futsal game. Several simulations were done with development kits, to certify if the designed system would be liable to be implemented. These simulations ran as expected, concluding that the system is practicable. At the time of the conception of the system devices, some problems emerged when making its boards, which led to setbacks that caused these not to be ready in time for presentation. The achieved results are only from the simulations performed with the development kits, which suggest that the system has the potential to be implemented in the near future.

Texte intégralENGLISH ABSTRACT: Airborne seeker antennas are usually enclosed within a dielectric radome for protection against their harsh operational environment. However the presence of a radome can introduce serious degrading effects on the radiation and electrical performance of the enclosed antenna. The degradation effect studied in this report is that of Bore Sight Error (BSE). BSE is a squint in the pointing accuracy of the antenna due to the enclosing radome. A ray-tracing approach is presented that is able to analyse the BSE of seeker radomes in general and is especially suited to electrically large radomes where other computational electromagnetic techniques become overly computationally intensive. The ray-tracing algorithm is wrapped in a GUI which, given the radome, antenna, polarisation and incidence plane parameters will compute the BSE for any set of requested scan angles. Close agreement was obtained with measured BSE performance available in literature. Due to easy setup and fast computation time it is demonstrated that the GUI can be efficiently used for iterative radome design and optimisation.
AFRIKAANSE OPSOMMING: Luggedrae soekantennes is normaalweg omhul binne ‘n dielektriese antennekoepel vir beskerming teen ‘n strawwe omgewing. Die teenwoordigheid van ‘n antennakoepel kan egter ernstige nadelige effekte op die straling en elektriese werkverrigting van die omhulde antenne hê. Die nadelige effek wat in hierdie verslag ondersoek word, is dié van die “Bore Sight Error (BSE).” BSE is ‘n afwyking in die akkuraatheid van die antenna se rigtingwysing as gevolg van die antennakoepel. Straal-natrekking wat die BSE van soek-antennekoepels in die algemeen kan analiseer word beskryf. Hierdie tegniek is veral gepas vir elektries groot antennekoepels waar die berekenige vir EM tegnieke te intensief raak. Die straalnatrekkingsalgoritme word omvat in ‘n grafiese gebruikerskoppelvlak. Gegee die parameters van die antennekoepel, antenne, polarisasie en invallende vlak, sal die BSE vir enige stel skandeerhoeke bereken word. Goeie ooreenstemming was verkry, vergeleke met gemete BSE vanuit die literatuur. Die eenvoudige opstel van die koppelvlak en vinnige berekeningstyd wys daarop dat die koppelvlak doeltreffend gebruik kan word vir iteratiewe antennekoepel ontwerp en optimering.

Texte intégralThe bandwidth of a microstrip patch antenna is expressed in terms of minimum achievable reflection coefficient using an equivalent circuit and the Bode-Fano theory. The bandwidth-reflection coefficient product is found to be proportional to antenna height and largely independent of feed probe position, for small bandwidths. The product can be computed directly from a numerical evaluation of the first-order Bode-Fano integral. Curves are presented showing how the product becomes limited by the feed probe inductance at very large bandwidths. It is concluded that this effect is unlikely to be a limit on the potential bandwidth of a practical patch antenna. If as a minimal correction the feed inductance is tuned out, the realized bandwidth with low order matching or optimal over-coupling shows the expected relationship to the theoretical limit.
