Design of Power Control Unit for Heat Recovery Device Used in Renewable Energy System
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015-11-22)
Heat recovery devices are used for saving energy especially for the renewable energy systems because of effective usage of electrical energy while providing air conditioning in spaces which needs fresh air. These devices ...
A New Quick Response Digital Control DC-DC Converter with Dynamic Unstable Gain
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015-11-22)
In this paper, we present a new quick response digital control dc-dc converter based on a dynamic unstable gain to improve transient response. In the proposed method, the proportional gain is set to the small value in the ...

Effect of infill wall and wall openings on the fundamental period of RC buildings
(WIT PRESS, ASHURST LODGE, SOUTHAMPTON SO40 7AA, ASHURST, İNGİLTER, 2013-07-08)
The effect of infill walls to stiffness of the structures has been known for a long
time and this effect has taken many of the earthquake regulations with empirical
relationships and equations into account. However, in ...

(SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2014-04-05)
In this study, a vector controlled permanent magnet synchronous motor (PMSM) drive fed by a two-level inverter which is connected to a boost converter with sliding mode control (SMC) for power factor correction (PFC) is ...
Domains of Dynamic Instability of FGM Conical Shells Under Time Dependent Periodic Loads
(Springer Nature, 2016-02)
On the basis of the dynamic version of linear Donnell type equations and with deformations before instability taken into account, the dynamic instability of simply supported, functionally graded (FG) truncated conical ...
Extension of the Darboux Frame into Euclidean 4-Space and its Invariants
(TÜBİTAK, 2017-11-23)
In this paper, by considering a Frenet curve lying on an oriented hypersurface, we extend the Darboux frame field into Euclidean 4-space E 4 . Depending on the linear independency of the curvature vector with the hypersurface’s ...
