IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Sampling Biases in Daily Average Temperatures From Greenland Climate Records
International Journal of Climatology, EarlyView.Biases are introduced in the calculation of daily average temperatures due to uneven sampling times for the investigated weather station network in Greenland. The figure shows the network, an example of a daily temperature cycle with daily averages based on all or only two observations and an overview of how the number of observations per day changes ...

Decision Threshold Setting in Binary Classification Problems—A Behavioral Lens
Journal of Operations Management, EarlyView.ABSTRACT When binary classification models are wrong, managers face misclassification costs. Although false positive outcomes imply unnecessary mitigation efforts, false negative outcomes imply overlooking the class of interest. Humans calibrate these ai models supporting operational systems by adjusting the decision threshold that translates ...

Technology Development Outsourcing: When to Join Forces With a Rival?
Journal of Operations Management, EarlyView.ABSTRACT Knowing the challenges of collaborating with a competitor in developing new technologies, firms sometimes still choose a competitor instead of a noncompeting technology provider. To explore why, this study adopts an inter‐organizational trust view to explain the formation of a technology development outsourcing relationship.

How Do Investors React to Supplier Exploitation? Event Study and Experimental Evidence
Journal of Operations Management, EarlyView.ABSTRACT Supplier exploitation, including financial squeezing, payment delays, and non‐contractual demands, is a pervasive form of corporate misconduct. This multi‐method study examines how investors interpret supplier exploitation amid competing ethical and financial considerations.

Code Analysis and Design for Successive Cancellation List Decoders
, 2022 The thesis investigates the potential of successive cancellation list (SCL) decoding for short-packet communications. First, SCL decoding is studied for transmission over binary-input memoryless symmetric channels. Codes are designed for specified decoding complexities that provide significant gains over the polar codes of the 5G standard.
