Neisseria meningitidis invasive disease is a major public health problem. Pharyngeal carriage is considered a prerequisite for invasive infection. Prevalence reaches 10% in general population and up to 30% in the 20–24 years age group. The aim of this study was to asses pharyngeal carriage prevalence in healthy subjects aged 18–24 years, and as secondary endpoints evaluate known risk factors, to identify...
Life cycle thinking (LCT) is one of the philosophies that has recently appeared in the context of the sustainable development. Some of the already existing tools and methods, as well as some of the recently emerged ones, which seek to understand, interpret and design the life of a product, can be included into the scope of the LCT philosophy. That is the case of the material and energy flow analysis...
This paper presents the optimal risk-sensitive controller problem for first degree polynomial stochastic systems with a scaling intensity parameter, multiplying the diffusion term in the state and observations equations and exponential-quadratic cost function to be minimized. The optimal risk-sensitive controller equations are obtained based on the optimal risk-sensitive filtering and control equations...
Indoor wireless communication takes interest, because the wires are cumbersome and generate less free space. For this type of communication, 2.4 Ghz is a widely used frequency among electronic equipments, mainly at home and industry. Patch antennas are very popular in wireless communications, specially at home and industry, because they are easy to design and easy to integrate with microwave integrated...
A deep knowledge of TCP performance on the Internet al large is intimately related to understanding the role of the underlying path characteristics (bottleneck rate, buffer sizes, end-to-end delay, loss rate) on the performance of dynamic TCP flows. The practical way to study the TCP performance is by simulating on a dumbbell topology, Internet statistically equivalent cross-traffic along with simulated...
