Real‐Time Implementation of Finite Control Set Model Predictive Control for BLDC Motors With Dynamic Speed References on ESP32

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper investigates the application of Finite Control Set Model Predictive Control (FCS‐MPC) for Brushless DC (BLDC) motor speed regulation under dynamic references, including sinusoidal, square, triangular, and sawtooth signals. A novel cost function is introduced to evaluate switching frequency effects, and the influence of different weighting ...

From Pirates to Professionals: Retaining a Sense of Integration During Venture Scaling

British Journal of Management, Volume 37, Issue 1, January 2026.
Abstract Our paper explains how organizations can build and sustain internal member identification during rapidly scaling transitions. Using a longitudinal case study of a UK scaling firm, we show how organizational members follow a recursive process of retaining and forgoing the past and foreseeing the future to create a transitional organizational ...

Increasing College Graduation Rates: What Works?

Higher Education Quarterly, Volume 80, Issue 1, January 2026.
ABSTRACT This article reports the findings of a study that examined five institutions that are outliers in terms of having higher‐than‐predicted graduation rates based on their student profiles and institutional resources. Notably, these institutions have accomplished this in the context of having limited or no endowments and far fewer financial ...

Exposure to traffic noise weakens territory defence in the Southern Emu‐wren (Stipiturus malachurus)

Ibis, Volume 168, Issue 1, Page 140-155, January 2026.
Anthropogenic noise has the potential to negatively impact wildlife by disrupting communication and reducing overall fitness. Understanding the effects of traffic noise on signalling behaviour can be important for managing threatened populations. The Southern Emu‐wren Stipiturus malachurus is a threatened, sedentary and territorial songbird, with a ...
