La libéralité est un acte translatif de propriété au profit d'une autre personne. Et c'est parce qu'il y a volonté de gratifier, de protéger par cet acte que nous nous sommes demandés si le gratifié pouvait inclure le vivant. Le sujet de la libéralité est une personne, l'objet de la libéralité est un bien, on ne contracte pas sur l'être. Or la technologie biomédicale a besoin aujourd'hui du matériau humain. La science rencontre alors la volonté d'individus qui souhaitent obtenir un produit, un matériau humain. C'est alors que les plus faibles peuvent se voir réifier. L'homme deviendrait-il alors objet de la libéralité ? La bioéthique pose des principes, mais les avancées scientifiques et surtout biotechnologies, les font reculer. Le droit délaisse alors son travail de qualification, de systématisation, il ne règle plus les impulsions personnelles. Pour ces raisons, nous avons pensé qu'une relecture de la summa divisio pouvait nous permettre de poser à nouveau des limites, de qualifier, de classer. Cela nous semble plus opportun d'arriver ainsi à la protection de l'ensemble du vivant plutôt que d'attribuer des droits à certains vivants non humains pour qu'ils puissent devenir bénéficiaires d'une libéralité notamment . Cette entrée dans la summa divisio ne doit pas conduire au confusionnisme avec l'homme et notamment la personne humaine, mais rappeler les liens, pour que ce qui est digne de respect ne soit pas dans la catégorie de l'avoir. / Liberality is a transitive act of property for the benefit of another person. And because there is a will of favoring and protecting someone by this act we asked if the presented can include the living. Liberality's subject is a person, liberality's object, is a good of patrimonial's nature, one can't contract about the being. But, biomedical technology needs today human material. Science meets then individual's wills who'd like to obtain human material. Consequently the weakest can be reified. In that case can the mankind become the object of the liberality ? Bioethics sets principles, but scientific progress and mainly biotechnical ones erase them. Then right abandons its work of qualification and systematization and only rules personal impulsions. That's why we have been thinking that a re-reading of the summa divisio could allow us to set the borders, to qualify and to classify again. It seems appropriate to arrive to the protection of all the living rather than attributing rights to some non-human livings in order to make them beneficiaries of a liberality. This entrance in the summa divisio must not lead to confusionism with man and in particular with the human person, but it should recall the connections, so that what's worthy of respect would not be in the having category.

A questão da existência de Deus acompanha o desenvolvimento intelectual de Tomás de Aquino e tem papel central em sua Suma de Teologia, na qual o filósofo desenvolve sua resposta através das conhecidas cinco vias para a prova da existência de Deus. O objetivo desta dissertação é percorrer o caminho traçado por Tomás de Aquino para chegar às cinco vias, mostrando a necessidade e a possibilidade da prova da existência de Deus como sujeito da Doutrina Sagrada. / The question of the existence of God follows the intellectual development of Saint Thomas Aquinas. It also plays a central role in his Summa Theologica, where the philosopher develops his answer trough “the five ways" of proving the existence of God. This dissertations aims to follow Saint Thomas Aquinas through the journey in developing \"the five ways\", by showing the need and the possibility to prove the existence of God as subject of the holy doctrine.

<p>Detta examensarbetet undersöker möjligheten att eliminera de amplitudtoppar som uppstår då flera sinussignaler av slumpmässiga frekvenser adderas. Det som eftersträvas är en signal innehållande flera godtyckliga frekvenser samtidigt som den bibehåller en låg Crestfaktor (eller PAPR). De metoder som tas fram implementeras sedan i en FPGA. Rapporten behandlar de metoder som undersökts både i teoretiska utvärderingar samt i en hårdvaruimplementation. Resultaten visar på att det inte finns någon enkel lösning på problemet, men att en kombination av metoder kan användas för att få en förbättring av signalens Crestfaktor. Metoderna bör balanseras utefter hur mycket av de icke önskvärda amplitudtopparna som ska elimineras, hur snabbt systemet måste vara, hur mycket resurser och hårdvara som finns tillgänglig, samt hur mycket brus som tolereras. De metoder som undersökts grundligast och även implementerats i hårdvara är initial fasfördelning, tid- och frekvensdomänbytesmetod och klippning, vilka tillsammans bildar ett system som genererar en önskvärd signal med låg Crestfaktor.</p><p> </p> / <p>This thesis investigates the possibility of eliminating the amplitude peaks that arise when several sinusoidal signals of random frequencies are added. The aim is a signal containing several arbitrary frequencies while retaining a low Crest factor (or PAPR). The methods to be developed are then implemented in an FPGA. The report deals with the methods which were examined, both in theoretical evaluations and in a hardware implementation. The results show that there is no easy solution, but that a combination of methods can be used to obtain an improvement of the signal’s Crest factor. These methods should be balanced with respect to how much of the undesirable amplitude is to be eliminated, how fast the system must be, what kind of resources and hardware that is available, and how much noise that can be tolerated. The methods investigated and implemented in hardware are initial phase distribution, time-frequency domain swapping algorithm and clipping, which together form a system that generates a desirable signal with low Crest factor.</p>
