In the Amazon region, few data are available on the impacts caused by the urban settlements found in the proximity of estuaries. In the estuary of the Caeté River, the focus of the present study, the nutrient input is ...
Peach and nectarine tree belongs to the species Prunus persica and is the third most produced fruit species in the world. Within Europe, Spain is a leading producer. Most of the crops are located in Catalonia (northeastern ...
The role of natural light in the health and wellbeing of users is a central subject to architectural design today. Sustainability and energy efficiency are also leading concerns. Therefore, new and existing buildings must ...
(English) Cities need to respond urgently to societal challenges, such as urbanization, changes in climate, and risk management. These challenges require innovative solutions in urban systems developed with citizens to ...
This research studies the topic of negotiation in the business field at a national and international level, and in particular the concept of negotiation capability, understanding that the negotiation processes generally ...
This thesis presents new applications of Gale duality to the study of polytopes with extremal combinatorial properties. It consists in two parts. The first one is devoted to the construction of neighborly polytopes and ...
With the proliferation of smart devices that require Internet connectivity anytime, anywhere, and the recent technological advances that make it possible, current networked systems will have to provide a various range of ...
The introduction of third generation (3G) technologies has caused a vast proliferation of wireless devices and networks, generating an increasing demand for high level Quality of Service (QoS). The wide spread of mobile ...
In an attempt to understand how Internet-like network and social networks behave, different models have been proposed and studied throughout history to capture their most essential aspects and properties. Network Creation ...
During the last decades, mobile network operators have witnessed an exponential increase in the traffic demand, mainly due to the high request of services from a huge amount of users. The trend is of a further increase in ...
Since its inception until today, the Internet has been in constant transformation. The analysis and monitoring of data networks try to shed some light on this huge black box of interconnected computers. In particular, the ...
The complexity of operation and management of emerging cellular networks significantly increases, as they evolve to correspond to increasing QoS needs, data rates and diversity of offered services. Thus critical challenges ...
The Ground Based Augmentation System (GBAS) is a local-area, airport-based augmentation of Global Navigation Satellite Systems (GNSSs) that provides precision approach guidance for aircraft. It enhances GNSS performance ...
NetZero Energy Buildings or buildings with almost zero energy consumption, are buildings with high energy performance in terms of operational energy, and which also seek to reduce their CO2 emissions in addition to other ...
Sensory neurons use sequences of electrical pulses (known as action potentials or spikes) to encode and transmit information of external temporal stimuli. Neural coding is the research field that studies the relationship ...
L’objectiu principal d’aquesta tesi és avançar en la comprensió del processament d’informació en xarxes neuronals en presència d’oscil lacions subumbrals. La majoria de neurones propaguen la seva activitat elèctrica a ...
Neutron capture cross sections are fundamental in the study of the slow neutron capture process of nucleosynthesis, also known as the s-process, which produces half of the observed solar system abundances of elements heavier ...
A recent sensitivity analysis done for the new generation of fast reactors [1] has shown the importance of improved cross section data for several actinides. Among them, the neutron-induced fission cross section of 240,242Pu ...
By 2050 the energy consumption is expected to increase considerably.The production might be mostly based on renewable energy mix driven by the nuclear fusion which could potentially deliver continuous, large-scale power ...
