Determinants of migratory flow in Europe: A fuzzy-set approach

2018

Abstract This article examines the variables that explain immigrants' decisions to remain in 18 European countries at three key stages of the European economic cycle: 2006 (economic boom), 2009 (the height of the economic and financial crisis), and 2014 (beginning of recovery). Population variables, environmental and health service variables, and economic variables were considered. Fuzzy-set qualitative comparative analysis (fsQCA) was used to conduct the analysis. The findings indicate that immigration behavior differs according to the stage of the economic cycle. When the economic cycle is in a favorable stage (boom and economic recovery), the GDP growth and land surface area of the recei…

Mass Estimation of Self-Contained Linear Electro-Hydraulic Actuators and Evaluation of the Influence on Payload Capacity of a Knuckle Boom Crane

2019

Abstract Self-contained linear hydraulic drives are characterized by having integrated the hydraulic power unit e.g. electrical prime mover, hydraulic pumps etc. and the hydraulic cylinder in a single compact unit. Compared to the hydraulic cylinder itself, the mass of the self-contained linear actuator is significantly larger. For some applications, e.g. crane manipulators the additional mass of the actuators compared to conventional valve-controlled hydraulics, may reduce the payload capacity, which is a central performance parameter. As a case study, a medium sized two link knuckle boom crane is modelled and by assuming the force capability of the hydraulic cylinders to be the limiting f…

Foreign (In)Direct Investment in Chinese Contemporary Art Game: The Case Studies of Uli Sigg, Guy Ullens and beyond, 1989-2013

2021

The boom in Chinese contemporary art is the result of China’s opening to foreign investment and private entrepreneurship in 1978, and the significant contribution by the transnational art enterprises of long-term patron-investor-collectors, such as Uli Sigg and Guy Ullens, between approximately 1989 and 2013. Through the opportunity offered by the gap between the private market mechanism and national heritage process for the “art game”, these investors used a variation of the controversial “Saatchi model” to generate high ROI. A further effect has been to bring CCA onto the global stage and complete the ecosystem of the art industry, building a foundation for the art economy of post-Mao Chi…

Booms, Busts and normal times in the housing market

2015

We assess the existence of duration dependence in the likelihood of an end in housing booms, busts, and normal times. Using data for 20 industrial countries and a continuous-time Weibull duration model, we find evidence of positive duration dependence suggesting that housing market cycles have become longer over the last decades. Then, we extend the baseline Weibull model and allow for the presence of a change-point in the duration dependence parameter.We show that positive duration dependence is present in booms and busts that last less than 26 quarters, but that does not seem to be the case for longer phases of the housing market cycle. For normal times, no evidence of change-points is fo…

Modeling of Friction Losses in Offshore Knuckle Boom Crane Winch System

2018

This paper presents a method for friction modeling in a hydraulically actuated multi motor winch system of an offshore knuckle boom crane. The method is based on a combination of a model of the variable displacement axial piston motor based on measurements from the sub supplier, and combined with a model of the remaining friction loss obtained from measurements on the full system.

Herbicide site specific spraying: use of simulations to study the impact of section width

2019

International audience; Site specific spraying is one way to reduce the amount of herbicide required to control weeds. The impact of boom section width was investigated by using simulated weed infestation maps with various weed coverage rates. Herbicide applications were simulated combining these virtual maps with various boom sections widths and various theoretical spray patterns. The objective was to quantify the herbicide reduction possibilities and potential under-application areas. Simulation derived results are analyzed using three indicators: i) the ratio between herbicide amount in the case of a targeted application and the amount deposited in the case of a full application, ii) the…

Booms and busts in housing markets: determinants and implications

2009

This study looks at real estate price booms and busts in industrialised countries. It identifies major and persistent deviations from long term trends for 18 countries and estimates the probabilities of their occurrence using a Random Effects Panel Probit model over the period 1980-2007. It finds that 1) most recent housing booms have been very persistent and of a significant magnitude; 2) there appears to be a strong correlation between the persistence and magnitude of booms and subsequent busts; 3) economic costs (in terms of GDP losses during the post-boom phase) depend significantly on the magnitude and duration of the boom and money and credit developments during that period; 4) a numb…
