Comparitive study of the influence of harmonic voltage distortion on the efficiency of induction machines versus line start permanent magnet machines [PDF]

open access: yes, 2012
Induction machines have nearly reached their maximal efficiency. In order to further increase the efficiency the use of permanent magnets in combination with the robust design of the induction machine is being extensively researched. These so-called line

CONTROL OF CYCLOCONVERTERS FOR FEEDING OF ASYNCHRONOUS MACHINES

open access: yesIFAC Proceedings Volumes, 1977
Abstract For the cycloconverter operation of thyristor bridges in anti-parallel connection, control techniques by which the output frequency can be considerably increased have been published. In the present investigation such an improved cycloconverter is used for the stator current control of a speed-controlled induction motor.

Genome‐Wide Association Study of Symptom Change Following Cognitive Behavioral Therapy for Common Mental Disorders

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Cognitive behavioral therapy (CBT) is a well‐established, evidence‐based treatment for common mental disorders such as depression, anxiety disorders, and obsessive‐compulsive disorder (OCD). However, treatment outcomes vary widely, and a substantial proportion of patients do not achieve sufficient improvement.

Innovating for Net‐Zero: Collaborative and Digital Decarbonisation Strategies in Sunset Industries' Global Value Chains

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Global net‐zero ambitions require transformative strategies to decarbonise carbon‐intensive global value chains (GVCs). This study examines how multinational enterprises (MNEs) in sunset industries integrate carbon capture technologies (CCT) with operational and supply chain dynamics (OSCD) to advance decarbonisation.

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

open access: yesChemie Ingenieur Technik, EarlyView.
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.
