Energy balance analysis in non linear dynamic equivalent systems.

Non-Linear Behavioral Modeling for DC-DC Converters and Dynamic Analysis of Distributed Energy Systems

Abstract: In modern distributed energy systems (DES), focus is shifting from the conventional centralized approach towards distributed architectures. However, modeling and analysis of these systems is more complex, as it involves the interface of multiple energy sources with many different type of loads through power electronics converters. The integration of power electronics converters allows...

Robust inversion of non-linear dynamic systems

Weight reduction is becoming increasingly important in products that undergo cyclic loading, such as cars, aeroplanes, wind turbines, etc. The novelty of these dramatic design changes will cause material fatigue to become one of the key design drivers in the development of cars, aeroplanes, wind turbines and require tools to accurately predict the life time of a construction. The life time can ...

on the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch

the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
