Abstract: In this paper, a new two-dimensional random switching frequency pulse-width-modulation (2D-RSF-PWM) method is proposed for variable frequency drives (VFDs). The proposed 2D-RSF-PWM method is ...

Sampling from probability distributions with known density functions (up to normalization) is a fundamental challenge across various scientific domains. From Bayesian uncertainty quantification to ...

Many types of economic problems require that we consider two variables at the same time. A typical example is the relation between price of a commodity and the demand or supply of that commodity. The ...

Evidence for affective forecasting errors is mixed. We review recent studies to determine whether taking a discrete versus dimensional approach to measuring affective forecasting could partly explain ...

Controlling the two-dimensional polymerization processes of two-dimensional covalent organic frameworks (2D COFs) is essential to fully realizing their distinct properties. Although most 2D COFs have ...

The departures of Reagan Arthur, who led Alfred A. Knopf, and Lisa Lucas, who held the top job at Pantheon and Schocken, came as a surprise to many in the company. By Alexandra Alter and Elizabeth A.
