Abstract Micro-data on robots have been very sparse in Germany so far. Consequently, a dedicated section has introduced the IAB Establishment Panel 2019 that includes questions number and type of used. This article describes background development survey questions, provides information quality data, possible checks steps data preparation. The resulting is aggregated industry level compared with...

This paper reviews some of the econometrics problems faced when estimating a rational addiction model of Becker and Murphy (1988) using panel data. This is illustrated with three empirical applications. The …rst application looks at cigarette consumption using macro panel data on American states over time (see Baltagi and Gri¢ n (2001)). The second application looks at liquor consumption using ...

in this paper, we investigated the necessity and effects of optimal control methods in the stability and performance of a micro-grid that operates in islanded mode. the micro-gird is consisted of a combine heat and power (chp), a capacitor bank (cb), photovoltaic panel (pv) as power generation sources. in addition, battery and the building electricity and thermal load are placed on the load sid...

Introduction: Natural materials are more efficient and attractive than synthetic materials. In this study, the sound absorption behavior by natural kenaf composite and Micro-Perforated Panel (MPP) at low and medium frequency region was investigated. Material and Methods: Initially, the results of kenaf fibers with a thickness of 10 mm were validated by the Finite Element Method (FEM) based on ...

Background: Patch pumps are a relatively new method of insulin delivery. This study explores the accuracy of patch-pumps by reporting on comparative pulse-accuracy study of two patch pumps. Methods: The accuracy of two patch pumps (Cellnovo, [Cellnovo Ltd., Swansea, UK] and OmniPod® [Ypsomed Ltd, Escrick, UK]) was evaluated micro-gravimetrically. Pulse accuracy was analysed by comparing single ...

This paper focuses on the power electronics used in the renewable energy systems especially in the photovoltaic applications. In recent years, interest in natural energy has grown in response to increased concern for the environment. Due to the limitations in the energy available from conventional sources, worldwide attention is being focused on renewable sources of energy. Especially, the ener...

There is strong evidence that house prices and consumption are closely synchronized. There is, however, disagreement over the causes of this link. This paper examines if there is a wealth effect of house prices on consumption. We use a rich household level panel data set with information about house ownership, income, wealth, and demographics for a large sample of the Danish population in the p...
