Abstract (sommario):
La conception des transmissions par engrenages s'oriente maintenant vers une réduction des nuisances sonores et vibratoires, après avoir optimisé les géométries. Depuis quelques années, l'erreur de transmission est considérée comme la principale excitation mesurable des systèmes engrenants. Dans le cadre de ce travail, nous avons cherché à établir un modèle expérimental du transfert entre l'erreur de transmission et le bruit d'engrènement d'un étage de réduction, prenant en compte les conditions de fonctionnement. Parmi les structures de modèles paramétriques disponibles, seul le modèle ARMAX

Abstract (sommario):
<p>Offshore power transmission is becoming an increasingly important issue. To moderate climate change, world leaders have set environmental goals that will be very difficult to reach without renewable power production and the removal of production units with high emissions. Wind power and electrification have been the focus in this report. Plans for the expensive wind power are already moving offshore. This report has made an attempt at suggesting a guideline for well-suited transmission systems, for wind power projects located at a distance in order to make them more economically attractiv

Abstract (sommario):
The current situation of insufficient investment in transmission tends to weaken the advantages of a deregulated power industry. These shortages mainly arise because of the risk of not recovering the cost of investing in new lines Location Marginal prices (LMPs) and Financial Transmission Rights (FTRs) are key elements in reducing these investment risks. Market participants are able to hedge against price fluctuations caused by transmission congestion through the purchase or sale of FTRs. The value of FTRs, which is tied to the difference in prices between locations in the network, would indic

There is sparse literature about HIV transmission in preterm infants. Eighty-two HIV-exposed preterm infants received birth polymerase chain reactions (PCRs). Five (6.1%) were HIV positive with all 5 mothers receiving inadequate antiretrovirals. Of the PCRnegative infants, 9 died and 87% of the survivors received further PCR testing which remained negative. With correct care, intrapartum transmission of HIV can virtually be eliminated.

Abstract (sommario):
Infectious diseases continue to cause significant financial, economic and health issues. Much work has been done on a variety of pathogens and host species with a wide range of approaches and methodologies from many disciplines, yet a full understanding of pathogen emergence has not been achieved. A greater understanding of transmission would benefit the management of control strategies, help to improve decision-making at first diagnosis of a host-pathogen interaction and possibly prevent further spread of epidemics and therefore new cases of emergence. A major gap in all these efforts appears

The study of vector biology is essential to understand leishmaniasis epidemiology and to implement cost-effective vector control measures.

Abstract (sommario):
To investigate how an infectious disease spreads, it is desirable to use the observed surveil­lance data to discover the underlying (often hidden) disease transmission networks. Previous studies have provided methods for inferring information diffusion networks in which each node corresponds to an individual person within the diffusion network. However, in the case of disease transmission, to effectively propose and implement intervention strategies, it is more realistic and reasonable for policy makers to study the diffusion patterns at a metapop­ulation level, that is, to consider disease tr

Many human behaviours are thought to depend upon cognitive capacities enriched with innate domain-specific knowledge. Underpinning this view is the hypothesis that evolution can shape cognition to include strong innate inductive biases. In this thesis, I re-examine that hypothesis with respect to a broad class of behaviours: those that we learn from other individuals. Taking human language as a test case, I present an analysis of the co-evolutionary process that underpins the formation of innate constraints on cognition for behaviours that are culturally transmitted through inductive inference

These delays imply significant additional costs for TSOs as well as society as a whole and put the transformation of the European energy system at risk.

Abstract (sommario):
This dissertation deals with four topics. The first three are in the same environment, the transmission paths. The fourth refers to the synthesis of subsystems and more specifically to two subsystems linked by any number of elastic elements. In the first topic it is proved that the solution of any linear mechanical system can be expressed as a linear combination of signal transmission paths. This is done in the framework of the Global Transfer Direct Transfer (GTDT) formulation for vibroacoustic problems. Transmission paths are expressed as powers of the transfer matrix. The key idea of the

Abstract (sommario):
Compressed video bitstream transmissions over wireless networks are addressed in this work. We first consider error control and power allocation for transmitting wireless video over CDMA networks in conjunction with multiuser detection. We map a layered video bitstream to several CDMA fading channels and inject multiple source/parity layers into each of these channels at the transmitter. We formulate a combined optimization problem and give the optimal joint rate and power allocation for each of linear minimum mean-square error (MMSE) multiuser detector in the uplink and two types of blind lin

Abstract (sommario):
<p>Power control is one of the technologies used to utilize the radio resources as efficient as possible in WCDMA. The transmission power is adjusted to transmit with the lowest power level possible while the required received signal quality is maintained. Since there are large variation in channel quality over time, the power has to be adjusted to compensate for these variations. During moments of bad channel conditions a high transmission power has to be used which will to a greater extent interfere with other users in the system. </p><p>To solve this problem a concept called transmission ti

Abstract (sommario):
<p>With the Internet expansion, real-time transmission over Internet is becoming a new promising application. Successful real-time communication over IP networks requires reasonably reliable, low delay, low loss date transport. Since Internet is a non-synchronous packet switching network, high load and lack of guarantees on data delivery make real-time communication such as Voice and Video over IP a challenging application to become realistic on the Internet. </p><p>This thesis work is composed of two parts within real-time voice and video communication: network simulation and measurement on t
