A Novel Solution for the Elimination of Mode Switching in Pump-Controlled Single-Rod Cylinders
2020
This paper concerns the stability issue of pump-controlled single-rod cylinders, known as mode switching. First, a review of the topic is provided. Thereafter, the most recently proposed solution for the elimination of mode switching is investigated and shown to result in unstable behavior under certain operating conditions. A theoretical analysis is provided demonstrating the underlying mechanisms of this behavior. Based on the analysis, a novel control strategy is proposed and investigated numerically. Proper operation and stability are demonstrated for a wide range of operating conditions, including situations under which the most recently proposed solution results in unstable behavior a…

Asiakkuudenhallinta ja sen hyödyt sekä haasteet palveluyrityksissä
2015
Asiakkuudenhallinta hyödyttää yrityksen liiketoimintaa useilla eri tavoilla. Jatkuvasti kasvavan palvelusektorin yrityksille se luo paljon lisäarvoa asiakas-suhteiden hallinnan ja kehittämisen muodossa. Tässä kandidaatin tutkielmassa on tarkasteltu asiakkuudenhallinnan hyödyntämistä palveluyrityksissä. Lisäk-si tutkielmassa on arvioitu asiakkuudenhallinnan haasteita ja mahdollisia on-gelmia palveluyrityksissä ja palvelutuotannossa yleisesti. Aluksi on tarkasteltu asiakkuudenhallintaa yleisellä tasolla, määritelty keskeiset käsitteet, kuvattu asiakkuudenhallinnan yleiset vaiheet ja prosessit sekä tarkasteltu asiakkuu-denhallinnan toteuttamisessa hyödynnettäviä tietojärjestelmiä.

La production et valorisation des compétences sur le marché du travail : des approches néo-classiques à l'économie des conventions
2003
This research starts from human capital theory to study the production and valorization of competences in the labor market. Using the potentials and constraints of the neo-classical approach, the incorporation of other areas of economic science as well as other social sciences contributions are proposed. We believe that the key notions economics of education - human capital and wages, are necessary but they are inadequate to explain the level of individual competence or his level of remuneration. We propose a coherent integration of the theoretical and methodological tools of economics of education as well as of the economics of conventions and economics of human resources. And it includes …
Development of Point-to-Point Path Control in Actuator Space for Hydraulic Knuckle Boom Crane
2020
This paper presents a novel method for point-to-point path control for a hydraulic knuckle boom crane. The developed path control algorithm differs from previous solutions by operating in the actuator space instead of the joint space or Cartesian space of the crane. By operating in actuator space, almost all the parameters and constraints of the system become either linear or constant, which greatly reduces the complexity of both the control algorithm and path generator. For a given starting point and endpoint, the motion for each actuator is minimized compared to other methods. This ensures that any change in direction of motion is avoided, thereby greatly minimizing fatigue, jerky motion,…
Producción de personas, reproducción de representaciones. Reflexiones sobre dos programas de capacitación en liderazgo
2020
The present paper addresses the question of the role Executive Education performs in the strengthening and reproduction of neoliberal ideology. It aims to critically reflect on the way selected contents and teaching activities operate jointly enabling or inhibiting certain perspectives regarding work in organizations. Two Leadership training programs are analyzed in this article, currently delivered by the two most prestigious business schools in Argentina: IAE Business School, and Torcuato Di Tella Business School. I begin with a general description of each one and proceed analyzing their educational proposals. Finally, the critical review reveals their consistency with a set of social rep…
Constructing relational space in early childhood education
2014
This paper examines early childhood education (ECE) by applying and developing relational-spatial perspectives on everyday life in educational institutions for young children. The aim is to investigate the dynamic process of construction of space and to illustrate with selected empirical episodes how this process occurs in ECE. Drawing on authors such as Soja and Bourdieu, the starting point for the analysis is that space is socially produced in everyday interactions in a process that intertwines the physical environment and concrete objects, personal interpretations of physical and cultural space, and cultural and collective views about space in ECE. We illustrate this process with ethnogr…
Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes
2022
Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…
Embodied energy and environmental impacts of a biomass boiler: a life cycle approach
2015
The 2030 policy framework for climate and energy, proposed by the European Commission, aims towards the reduction of European greenhouse gas emissions by 40% in comparison to the 1990 level and to increase the share of renewable energy of at least the 27% of the European's energy consumption of 2030. The use of biomass as sustainable and renewable energy source may be a viable tool for achieving the above goals. However, renewable energy technologies are not totally clean because they cause energy and environmental impacts during their life cycle, and in particular they are responsible of air pollutant emissions. In this context, the paper assesses the energy and environmental impacts of a …
