Comparative Evaluation Of Investigation Methods For Estimating The Load-Dependent State Of Charge And End Of Discharge Of A Multirotor Uav Battery, Hanna Dibbern, Morten Roßberg, Claudia Werner

Journal of Aviation Technology and Engineering

As the scope of multirotor unmanned aerial vehicle (UAV) applications increases, more attention is being paid to UAV energy requirements, which vary depending on the mission profile. To obtain accurate information about the UAV battery during flight, the idea of a digital twin including a battery state estimation model is promising. For battery state estimation, a Kalman filter combination is the preferred approach in the literature. Comparing different Kalman filters, the unscented Kalman filter has a more accurate estimation for nonlinear systems compared to the extended Kalman filter. In the application of UAV flight with load-dependent flight missions, the comparison …

Education For Self-Control: Some Similarities Between Dewey’S Experience And Education And Locke’S Theory Of Rational Agency, Atli Harðarson Nov 2023

Education For Self-Control: Some Similarities Between Dewey’S Experience And Education And Locke’S Theory Of Rational Agency, Atli Harðarson

Education and Culture

One of the themes that runs through Dewey’s Experience and Education is an argument to the effect that education aims at self-control. The details of this argument reveal close affinity between Dewey’s philosophy of education and the ideals of the Enlightenment. They are also strikingly similar to John Locke’s thoughts about freedom and education published in the seventeenth century. Comparison of their texts shows that Dewey and Locke worked with similar distinctions between positive and negative freedom. They both saw freedom and guidance as compatible, and conceived of self-control as dependent on autonomy-friendly habits instilled through education.

Deweyan “Soul” As Conceived In His Early Work, Becky L. Noël Smith, Randy Hewitt Nov 2023

Deweyan “Soul” As Conceived In His Early Work, Becky L. Noël Smith, Randy Hewitt

Education and Culture

The term “soul” is found throughout John Dewey’s work, particularly when discussing self-realization and meaningfulness. Soul can be easily associated with religious connotations, and yet it is well accepted that he did not imply such. So, then, what did he mean? In his early writings, he shifted away from theologically inspired language and toward a conception composed in naturalized terms. This, no doubt, can be confusing to uninitiated readers. While extensive analyses have been written on his philosophy of spirit and metaphysics, they can leave one wondering: what is a conception of soul that is consistent with Dewey’s philosophy of …

A Framework For Examining The Relationship And Classifying Instructional Strategies, Methods, And Techniques, Victoria L. Lowell, Lucia Urena-Rodriguez

Purdue University Libraries Open Access Publishing Fund

Globally, educators and researchers use different terms to describe instructors’ approaches when presenting instructional material in formal and informal settings. Terms commonly used to describe instructional approaches include teaching/instructional strategy, teaching/instructional method, and teaching/instructional technique. Although practicing educators and researchers use these words interchangeably, they have different meanings, leading to confusion regarding the relationship between these approaches and their proper usage when describing instructional practices. The research-to-practice gap in all fields exacerbates the issue, as practitioners and researchers may use different terms. As a result, there is a need for consistency in the terms used to describe instructional approaches across …
