CH of masonry materials via meshless meso-modeling

2014

In the present study a multi-scale computational strategy for the analysis of masonry structures is presented. The structural macroscopic behaviour is obtained making use of the Computational Homogenization (CH) technique based on the solution of the boundary value problem (BVP) of a detailed Unit Cell (UC) chosen at the meso-scale and representative of the heterogeneous material. The smallest UC is composed by a brick and half of its surrounding joints, the former assumed to behave elastically while the latter considered with an elastoplastic softening response. The governing equations at the macroscopic level are formulated in the framework of finite element method while the Meshless Meth…

Small Scale Gasification Application and Perspectives in Circular Economy

2018

Abstract Gasification is the process converting solid fuels as coal and organic plant matter, or biomass into combustible gas, called syngas. Gasification is a thermal conversion process using carbonaceous fuel, and it differs substantially from other thermal processes such as incineration or pyrolysis. The process can be used with virtually any carbonaceous fuel. It is an endothermic thermal conversion process, with partial oxidation being the dominant feature. Gasification converts various feedstock including waste to a syngas. Instead of producing only heat and electricity, synthesis gas produced by gasification may be transformed into commercial products with higher value as transport f…

Estimation of the Amount of Disposed Antibiotics

2019

The impact of the antibiotics in the environment is not well understood yet. Moreover, the total amount of antibiotics that are ending up in the environment as solid waste is not known and cannot be rigorously determined as many variables are influencing the determination of their concentration. The present article is focused on the estimation of the amount of non-prescribed antibiotics that are used in different European countries. Particular attention is paid to the class of beta-lactams, as they are responsible for a considerate share of the antimicrobial resistance. The primary purpose was the estimation of the quantity of non-prescribed antibiotics that might reach the environment as s…

Investor Inattention to All-Cash Acquisition Announcements: A Joint Day-Time Analysis in the Spanish Market

2021

Prior studies suggest that investors have limited attention, which determines the speed with which information is incorporated into share prices and, in turn, affects the efficiency of the markets. Unlike other corporate events, the information contained in an acquisition announcement is generally less standard and more complicated to process. Therefore, investor inattention is less likely around this event. In this study we test the existence of investor inattention for a sample of all-cash acquisition announcements of listed and unlisted target firms released by listed Spanish firms from 1998 to 2018. Cash acquisitions allow us to control for the strategic behavior of overvalued companies…

Network governance arrangements and rural-urban synergy

2021

Increasing attention has been paid to the importance of balanced rural–urban interaction to sustainable regional development. Yet, our knowledge on the elements of network governance for such interaction is scarce. The aim of this paper is to study what kind of network governance arrangements currently exist, how they can be improved, and whether evolutionary governance paths can be identified. We analyse five existing and evolving cases of functioning rural–urban interaction in European Union (EU) member states, using a network governance framework as an analytical lens. We supplement the governance analysis with examining what kind of spatial understanding or combination of di…

Ny arbeids- og velferdsforvaltning : oppretting av NAV-kontorer i kommunene : rapport fra en pilotstudie høsten 2006

2006

1.juli 2006 ble den Nye Arbeids- og Velferdsforvaltning opprettet. Det er den største omorganisering som er skjedd innen velferdstjenesteområdet i Norge noen gang. 16000 ansatte er involvert og alle landets kommuner blir engasjert i denne. For å få en oversikt over reformen og over området som endres ble denne rapporten laget. Rapporten er derfor en beskrivende rapport både når det gjelder fortid om hvordan de tidligere etatene ble til og fungerte og når det gjelder nåsituasjonen for reformen. Fortiden beskrives i en gjennomgang av historien bak, mens nåsituasjonen beskrives dels ved en gjennomgang av reformens ulike dokumenter og ved svarene som fremkom i en intervjurunde foretatt i forhol…

Slāpekļa oksīda metabolisma īpatnības fiziski aktīviem 1.tipa cukura diabēta pacientiem

2017

1. tipa cukura diabēta (1TCD) pacientiem fiziskas aktivitātes (FA) ir spējīgas uzlabot endotēlija funkciju, uzlabojot slāpekļa oksīda (NO) metabolismu un bioaktivitāti. Darba mērķis bija izvērtēt un salīdzināt NO un tā metabolītu līmeņus serumā un urīnā starp fiziski aktīviem un neaktīviem 1TCD pacientiem, kā arī spriest par iegūto rezultātu saistību ar cukura diabēta (CD) vēlīnajām komplikācijām. Metodes: Pētījumā tika iesaistīti 295 dalībnieki ar diagnosticētu 1TCD un 70 dalībnieki bez glikozes tolerances traucējumiem. Dalībnieku FA noteikta aizpildot brīvā laika fiziskās aktivitātes (BLFA) anketas, kurās piedāvāta 21 dažāda aktivitāte, pie kuras pacientiem bija jānorāda biežums (reizes m…

From Focused Thought to Reveries: A Memory System for a Conscious Robot

2018

© 2018 Balkenius, Tjøstheim, Johansson and Gärdenfors. We introduce a memory model for robots that can account for many aspects of an inner world, ranging from object permanence, episodic memory, and planning to imagination and reveries. It is modeled after neurophysiological data and includes parts of the cerebral cortex together with models of arousal systems that are relevant for consciousness. The three central components are an identification network, a localization network, and a working memory network. Attention serves as the interface between the inner and the external world. It directs the flow of information from sensory organs to memory, as well as controlling top-down influences…

Sustainable Method Using Filtering Techniques for a Fermentation Process State Estimation

2020

Winemaking is concerned about sustainable energy availability that implies new methods for process monitoring and control. The aim of this paper is to realize a comparative analysis of the possibilities offered using estimation techniques, balances, and filtering techniques such as the Kalman filter (KF) and the extended Kalman filter (EKF), to obtain indirect information about the alcoholic fermentation process during winemaking. Thus, an estimation solution of the process variables in the exponential growing phase is proposed, using an extended observer. In addition, two estimation solutions of this process with the EKF and an estimation of the decay phase of the fermentation process are …
