How to control SiC BJT with high efficiency?

SiC Bipolar Junction Transistor has many benefits such as low on-state voltage drop, high switching speed and high maximum operating temperature. However it has one major disadvantage that it needs current to be turned on. This causes an increased power requirement of the driver circuit compared to voltage controlled devices like MOSFETs and IGBTs. The proposed driving concept is based on a verifi

Towards a Resource-based Theory of Value Appropriation: An Appropriation Factor Framework

This paper highlights the problem resource-based theory faces in explaining value appropriation and proposes a framework that addresses how resources affect bargaining power and value appropriation. The appropriation factor framework presented in this paper states that particular resources, termed appropriation factors, affect bargaining power, and thus the possibility for economic agents of appro

Theoretical Isolation and Symmetry in the Resource-based View

Theorizing simplifies reality by means of "isolation" whereby some phenomena or aspects thereof are excluded from consideration. Using the case of the resource-based view, we discuss how theorists isolate. We develop a case for symmetrical isolations, show that the RBV violates a symmetry requirement, argue that a more symmetrical RBV implies novel insights in value creation and appropriation, and

A case study of impersonation from a security systems point of view

A professional impersonator has been studied when training his voice to mimic two target speakers. Training was performed by listening and/or using the output from a speaker verification system as feedback. Tests after training showed a significant increase in verfication score.
