This paper studies the relationship between partner selection and socioeconomic status (SES) attainment and mobility in five rural parishes in southern Sweden, 1815-1894. Three different aspects of partner selection are considered: age, social origin (father’s SES), and geographical origin. We use an individual level database containing information on the socioeconomic origin (parental land holdin
Fredrika Bremer and Erik Gustaf Geijer were friends and both were intensely engaged in the philosophical and political questions about the relation between thinking (ande, Geist) and reality (Natur). Both became liberals, in an hegelian mode, but Geijer never advocated women's rights, which Fredrika Bremer did.
Economic theory commonly distinguishes between different time horizons such as the short run and the long run, each with its own relationships and its own dynamics. Engle (1974) proposed a bandspectrum regression to estimate such models. This paper proposes a new estimator for non-stationary panel data models, a bandspectrum cointegration estimator. The bandspectrum cointegration estimator uses fi
A class-C CMOS harmonic VCO maximizes the oscillation amplitude by operating the active devices operating in class C, while the bias-current noise is naturally rejected by the topology. Drawing 1.4mA from a 1V supply, the 0.13µm CMOS prototype exhibits an average phase noise of -130dBc/Hz at 3MHz offset over the 4.90-to-5.65GHz tuning range, for an FoM of 194.5dBc/Hz.
The paper gives a review of pole-placement design for systems with known parameters, then focuses entirely on the servos. Adaptive pole-placement algorithms are discussed, leading to the formulation of explicit and implicit schemes, and simulation of the behaviour of the alorithms is given.
Massive multiple-input multiple-output (MIMO) is one of the main candidates to be included in the fifth generation (5G) cellular systems. For further system development it is desirable to have real-time testbeds showing possibilities and limitations of the technology. In this paper we describe the Lund University Massive MIMO testbed – LuMaMi. It is a flexible testbed where the base station operat
