This paper explores the validity of assuming the existence of a Swedish R&D paradox based on the relationship between R&D expenditures and economic growth, and what implications the existence of such a paradox ought to have on policies that concern R&D expenditure. Consequently, in the first instance, the relationship between Gross Expenditure on Research & Development (GERD) and G
In this paper, we propose a new system-level design language, called SystemJ. It extends Java with synchronous reactive features present in Esterel and asynchronous constructs suitable for modelling globally asynchronous locally synchronous systems. The strength of SystemJ comes from its ability to offer the data processing and encapsulation elegance of Java, Esterel-like reactivity and synchrony,
The FIR function of the proposed filter is realized by integrating weighted signal currents in a given time window on a capacitor The input signal voltage is weighted into multiple voltages according to the FIR requirement through a resistor ladder. A switching network sequentially connects the weighted voltages to a linear transconductor which converts the voltage to current and charges the capac
Recently, the multiplexing efficiency metric is proposed for characterizing the MIMO performance of terminal antennas. Here, we show that it can also provide useful insights into the impact of user on MIMO terminal performance. In particular, the impact of user hand and head on the efficiency and correlation of a MIMO antenna can be conveniently quantified using the multiplexing efficiency metric.
In addition to the basic regulatory functions, a batch control system must support production planning and scheduling, recipe management, resource allocation, batch report generation, unit supervision and exception handling. A closed-loop framework is presented in this work that integrates decision support tools required at the different levels of a decision-making hierarchical batch control syste
We revisit a Swedish comprehensive school reform first evaluated by Meghir and Palme (2005). This reform increased years of schooling and abolished tracking. We extend the original analysis to the full population and introduce an improved education measure. Our results confirm the original overall finding of small average earnings effects. However, we find considerably larger increases in educatio
Wear mechanisms and failure modes were investigated for autoclave-cured, woven carbon fiber-reinforced polymer (CFRP) composite gears in a mesh with a surface-hardened, 42CrMo4 steel pinion. The reference gears (m = 1 mm, b = 2 mm, z = 20) were tested at torque levels ranging from 0.4 Nm to 0.8 Nm. The temperature was monitored with a thermographic camera, while the gear damage and wear volume wer
Patients with immune-mediated kidney diseases are at increased risk of severe coronavirus disease 2019 (COVID-19). The international rollout of COVID-19 vaccines has provided varying degrees of protection and enabled the understanding of vaccine efficacy and safety. The immune response to COVID-19 vaccines is lower in most patients with immune-mediated kidney diseases; either related to immunosupp
Six species of beetles new to the Swedish fauna are presented. Megasternum immaculatum (Stephens, 1829) (Hydrophilidae) has been confirmed to occur in the north of Sweden in natural conditions as well as in the south, living in compost. Carpelimus punctatellus (Erichson, 1840) (Staphylinidae) was found using suction sampling in a xerotherm ruderal area in the city of Malmö. Meligethes sulcatus Bri
In a wireless communication system, the radio propagation channel is a complicated component to characterise. Channel sounding equipment thus has to meet specific criteria to extract the desired channel parameters. In this study, the authors outline the development and validation of a vector network analyser (VNA) based channel sounder for the frequency range from 1 to 50 GHz using radio-over-fibr
gamma -carboxylated polypeptides were detected in the human kidney by immunohistochemistry with a monoclonal antibody (M3B) specific for gamma -carboxyglutamyl residues. An similar to 70-kDa gamma -carboxylated protein, subsequently identified as prothrombin, was isolated from the intracellular compartment of cultured human embryonic kidney (HEK293) cells by immunoaffinity chromatography on M3B-co
