The Distribution Function of a Probability Measure on a Linearly Ordered Topological Space

In this paper, we describe a theory of a cumulative distribution function on a space with an order from a probability measure defined in this space. This distribution function plays a similar role to that played in the classical case. Moreover, we define its pseudo-inverse and study its properties. Those properties will allow us to generate samples of a distribution and give us the chance to calculate integrals with respect to the related probability measure

Effect of agro-climatic conditions on near infrared spectra of extra virgin olive oils

Authentication of extra virgin olive oil requires fast and cost-effective analytical procedures, such as near infrared spectroscopy. Multivariate analysis and chemometrics have been successfully applied in several papers to gather qualitative and quantitative information of extra virgin olive oils from near infrared spectra. Moreover, there are many examples in the literature analysing the effect of agro-climatic conditions on food content, in general, and in olive oil components, in particular. But the majority of these studies considered a factor, a non-numerical variable, containing this meteorological information. The present work uses all the agro-climatic data with the aim of highlighting the linear relationships between them and the near infrared spectra. The study begins with a graphical motivation, continues with a bivariate analysis and, finally, applies redundancy analysis to extend and confirm the previous conclusions.Peer Reviewe

Analysis of the economic feasibility and reduction of a building’s energy consumption and emissions when integrating hybrid solar thermal/PV/micro-CHP systems

The aim of this paper is to assess the performance of several designs of hybrid systems composed of solar thermal collectors, photovoltaic panels and natural gas internal combustion engines. The software TRNSYS 17 has been used to perform all the calculations and data processing, as well as an optimisation of the tank volumes through an add-in coupled with the GENOPT® software. The study is carried out by analysing the behaviour of the designed systems and the conventional case in five different locations of Spain with diverse climatic characteristics, evaluating the same building in all cases. Regulators, manufacturers and energy service engineers are the most interested in these results. Two major contributions in this paper are the calculations of primary energy consumption and emissions and the inclusion of a Life Cycle Cost analysis. A table which shows the order of preference regarding those criteria for each considered case study is also included. This was fulfilled in the interest of comparing between the different configurations and climatic zones so as to obtain conclusions on each of them. The study also illustrates a sensibility analysis regarding energy prices. Finally, the exhaustive literature review, the novel electricity consumption profile of the building and the illustration of the influence of the cogeneration engine working hours are also valuable outputs of this paper, developed in order to address the knowledge gap and the ongoing challenges in the field of distributed generation

Pre- and postsaddle fission dynamics using lead on proton reactions in complete kinematic measurements

Fission is a clear example of the evolution from a metastable to a quasi-equilibrium regime. The dynamics of this process can be described in terms of the potential-energy surface, friction, diffusion and inertia. The investigation of different experimental observables has shown evidences that the nuclear friction parameter or viscosity of the medium changes with the deformation, but also with the nuclear temperature. However, these ideas are still under debate because these conclusions could be biased by the experimental conditions. Therefore, we propose to investigate these effects with complete kinematic measurements of the fission products at high excitation energy, low angular momentum and small compound nucleus deformation, where dissipative effects should manifest in a clear way. In this work, we will report recent results obtained at GSI (Darmstadt) for the reactions 208Pb(370A, 500A, and 650A MeV) + p and 208Pb(500A MeV) + 27Al. These reactions fulfill the optimum conditions for the investigation of dissipative effects in fission. Moreover, the use of the SOFIA (Studies On FIssion with Aladin) setup together with the inverse kinematics technique allowed us to construct new observables that provide information on the fissioning compound nucleus, and its saddle and scission configurations. In particular, the unambiguous identification in mass and atomic number of both fission fragments, obtained for the first time in this experiment, was a key achievement. Total and partial fission cross sections, light-charged particle multiplicities and charge distributions of the fission fragments are used to characterize the fission dynamics at small deformation. We also present the results concerning to the neutron excess and isotopic widths of the fission fragments, their kinematic properties and the average pre- and postscission neutron multiplicities, which should help us to investigate the postsaddle dynamics
