AN EXPERIMENT IN MAGNETISM

Animal Rights Consideration is a Necessity in Conducting an Experiment

An Introduction to Natural Experiment Studies

در دو سخن سردبیری شماره‌های قبل به مطالعات مداخله‌ای (Interventional and/or experimental studies) [1] و مطالعات نیمه تجربی (studies Quasi-experiment) [2] پرداختیم. همان جا، به این نکته اشاره کردیم که برای اندازه‌گیری کارآیی یک دارو، واکسن، برنامه بهداشت عمومی و متغیرهای دیگری از این دست، مطالعات مداخله‌ای بهترین گزینه هستند. تقسیم تصادفی و کورسازی از مؤلفه‌های اساسی یک مطالعه مداخله‌ای است [1]....

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Magnetism in olivine-type LiCo(1-x)Fe(x)PO4 cathode materials: bridging theory and experiment.

In the current paper, we present a non-aqueous sol-gel synthesis of olivine type LiCo1-xFexPO4 compounds (x = 0.00, 0.25, 0.50, 0.75, 1.00). The magnetic properties of the olivines are measured experimentally and calculated using first-principles theory. Specifically, the electronic and magnetic properties are studied in detail with standard density functional theory (DFT), as well as by includ...
