EFFECT OF VARIABLE INPUT AND OUTPUT ON THE CHARACTERISTICS OF A STEERING SYSTEM WITH EPS (ELECTRIC POWER SYSTEM)

Journal of KONES. Powertrain and Transport, 2015
The complexity of the process of controlling the steering system assistance causes that the assistance units, designed as the control systems, change their characteristics depending on the frequency and amplitude of the torque applied to the steering wheel as well as on the frequency and amplitude of the force applied to the gear toothed bar.

ESG, Bank Debt and Firm Value: A Signaling Perspective

Journal of International Financial Management &Accounting, EarlyView.
ABSTRACT This paper delves into the influence of bank debt in shaping the relationship between environmental, social, and governance (ESG) performance and a firm's value. As a result of the superior informational and monitoring functions of bank borrowers in their lending relationships, we argue that a firm's degree of bank debt might signal the ...
