Despite their technological importance, studying the properties of alloys with first principles methods remains challenging. In cases AlxGa1-xN and BaxSrx-1TiO3 (BST), whose most important are governed by point defects, explicit simulation can be a computationally demanding task due to random occupation Al Ga on cation sites in AlGaN Ba Sr A-sites BST. this work, interpolation between end membe...

tthe uncertainty estimation and compensation are challenging problems for the robust control of robot manipulators which are complex systems. this paper presents a novel decentralized model-free robust controller for electrically driven robot manipulators. as a novelty, the proposed controller employs a simple gaussian radial-basis-function network as an uncertainty estimator. the proposed netw...

in this paper the problem of minimizing the total transmitting power subject to a fixedtotal bit rate in ofdm systems is considered. upper bounds on transmitting power and bit rate ofeach subcarrier can also be taken into account. in practice, the number of bits of each subcarriershould be integer and nonnegative. in this paper an analytical optimal solution is derived for thecase of assuming t...
