Stochastic multicriteria evaluation of district heating systems considering the uncertainties

2018

It is of great importance to choose a suitable district heating (DH) system for a specific DH area from the economics, environment and energy (3E) points of view. This is a multicriteria decision making problem, in which the criteria performance values (PVs) and weighting are characterized by uncertain or imprecise information. In this study, seven candidate DH systems are evaluated from the viewpoints of 3E by the stochastic multicriteria acceptability analysis (SMAA) method. SMAA is able to handle the uncertainties of the criteria PVs and the weighting at the same time. These uncertainties are very common and typical in real-life, but in most cases are not treated judiciously or just negl…

A simple procedure to improve the pressure evaluation in hydrodynamic context using the SPH

2009

In literature, it is well know that the Smoothed Particle Hydrodynamics method can be affected by numerical noise on the pressure field when dealing with liquids. This can be highly dangerous when an SPH code is dynamically coupled with a structural solver. In this work a simple procedure is proposed to improve the computation of the pressure distribution in the dynamics of liquids. Such a procedure is based on the use of a density diffusion term in the equation for the mass conservation. This diffusion is a pure numerical effect, similar to the well known artificial viscosity originally proposed in SPH method to smooth out the shock discontinuities. As the artificial viscosity, the density…

Evaluation of a short food frequency questionnaire used among Norwegian children.

2012

Objective: The aim of this study was to evaluate a short food frequency questionnaire (FFQ) against a four-day precoded food diary (PFD) with regard to frequency of food intake among Norwegian 9- and 13-year-olds. Subjects and design: A total of 733 9-year-olds and 904 13-year-olds completed first a short FFQ and one to two weeks later a four-day PFD. The short FFQ included questions about 23 food items, including different drinks, fruits, vegetables, bread, fish, pizza, sweets, chocolate and savoury snacks. The PFD covered the whole diet. Results: When comparing mean intake from the PFD with comparable food items in the FFQ, all food items showed that increasing intake measured with the PF…

Impact of conventional and non-conventional processing on prickly pear ( Opuntia spp.) and their derived products: From preservation of beverages to …

2017

Abstract Background In recent years, both food researchers and food industry have shown growing interest in Opuntia fruits, as they constitute a good source of phytochemicals such as phenolics, vitamin C, vitamin E, polysaccharides and betalains. Many of these compounds have shown antioxidant, anti-cancer, antiatherosclerotic and/or hepatoprotective properties. Moreover, the fruit is also a source of dietary fibers, which promote bowel transit, thus preventing constipation. Scope and approach Due to these properties, Opuntia fruits are considered as functional products offering numerous health benefits when are consumed as fresh or processed product. However, these compounds can lose their …

Why (not) assess? Views from the academic departments of Finnish universities

2010

In Europe, national quality assurance systems of higher education have begun to be established. In Finland, this development has had the consequence of forcing universities to take notice of assessment procedures. However, little is known about the procedures taking place in individual academic departments as a result of this pan‐European trend. This article describes how academics currently comprehend quality assessment, paying particular attention to self‐evaluations and quality assurance systems. Altogether, the paper casts light on how academics are responding to the increasing university assessment activities.

Determining the RMB Exchange Regime

2011

Although China has claimed since 2005 that it will move towards a more market-oriented system of managing its foreign exchange, it has remained, in part, a managed economic system. This chapter examines the relative importance of fundamentalist, chartist and currency arrangements in determining the RMB exchange regime using both traditional linear and non-linear artificial intelligence models. We find that the emphasis on the US dollar as a reference currency has declined. Fundamentalist forces are becoming strong determinants of the currency exchange. The genetic programming approach is among the best performing in minimizing forecasting error.

Male violence against women: Integration between psychological and neuroscientific data and their use in forensic evaluation for the judgments

2020

Human growth and development, starting from conception, are characterized by a progressive increase in body and organ dimensions, as well as specific functional maturity, under the influence of genetic as well as environmental and epigenetic determinants. Beyond a possible normal familial trait, increased fetal growth resulting in a large for gestational age newborn, isolated macrosomia or that associated with congenital malformation, can be attributable to both maternal metabolic and genetic pathology. Overgrowth syndromes are a heterogeneous group of diseases characterized by excessive tissue development often concomitant to neurodevelopmental involvement. Recently, an increased risk of f…

Analyse pseudo-longitudinale de la transformation de l'offre des formations d'ingénieurs en France

2010

En France, comme ailleurs dans la zone, le déclin des emplois industriels est profond, de plus de 6 millions il y a quarante ans, le rythme actuel de destruction d'emploi est proche d'une centaine de milliers pas an. Accéléré par la crise actuelle, l'enfoncement du seuil de trois millions d'emplois industriels est aujourd'hui inéluctable à court terme. De seul cadre technique de l'industrie, le métier d'ingénieur a lui aussi évolué. Le seul fait d'évoquer les métiers de l'ingénierie financière est là pour le rappeler, d'une part et d'autre part les firmes industrielles se sont profondément transformées puisque le taux d'ingénieurs diplômés dans l'emploi peut y représenter plus du tiers. Cet…
