On doing relevant and rigorous experiments: Review and recommendations.
(2018)
Although experiments are the gold standard for establishing causality, several threats can undermine the internal validity of experimental findings. In this article, we first discuss these threats, which include the lack ...
A simulation study of threats to validity in quasi-experimental designs: interrelationship between design, measurement, and analysis
(2016)
The Campbellian tradition provides a conceptual framework to assess threats to validity. On the other hand, different models of causal analysis have been developed to control estimation biases in different research designs. ...
The impact of a cash transfer programme on tuberculosis treatment success rate: a quasi-experimental study in Brazil
(BMJ Publishing Group, 2019)
Sinusoidal PWM Techniques Comparison for the Quasi-Y-Source Inverter
(2021-10-01)
Impedance network inverters (INIs) have emerged as an alternative to improve traditional inverters, allowing their operation as a buck-boost-type converter, through the utilization of the “shoot-through” conduction state, ...
Design and test of an adjustable quasi-zero stiffness device and its use to suspend masses on a multi-modal structure
(2021-05-01)
In some applications, such as ground vibration testing in the aerospace industry, it is of interest to observe the modal behaviour of a slender structure while it is statically loaded. One way of statically loading such a ...
A CMOS Micro-power, Class-AB Flipped Voltage Follower using the quasi floating-gate technique
(Universidad Nacional de Colombia, 2018)
Inversor multiníveis quasi-Z-source com fonte CC única e compartilhamento de potência ativa entre os módulos
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2019-07-26)
Due to its ability to provide Maximum Power Point Tracking (MPPT) control and independent
regulation of the DC bus voltage, this makes the inverter quasi-Z-Source (qZS) an attractive
candidate for applications in ...
