Performance Analysis of Linear Permanent Magnets Synchronous Motor by Scalar Control Method (v/f)
(Trans Tech Publications Ltd, 2014)
This study is conducted to improve the performance of Linear Permanent Magnet Synchronous Motor by using Scalar Control Method. To do this, open and closed loop control methods are used. The study is modeled with MATLAB / ...
Kinetics, thermodynamics, and equilibrium evaluation of adsorptive removal of methylene blue onto natural illitic clay mineral
(Desalination Publ, 2014)
The natural illitic clay mineral (NICM) has been used as a low cost and highly effective adsorbent in the removal of a toxic cationic dye, methylene blue (MB), from aqueous solution by a batch adsorption technique. The ...
Synthesis of cyclohexane derivatives including Br, Cl, N, O, and S at 1,2,4,5-positions: selectivity in addition reactions
(Pergamon-Elsevier Science Ltd, 2014)
Brominations of mono addition products of 1,4-cyclohexadiene with 2,4-dinitrobenzenesulfenyl chloride (RSCI) selectively gave 1R(S),2R(S),4R(S),5R(S)-4,5-dibromo-2-(2,4-dinitrophenylthio)cyclohexyl acetate and 1R(S),2R(S ...
The effects of chemical attacks on physical and mechanical properties of concrete produced under cold weather conditions
(Elsevier Sci Ltd, 2014)
This study investigates the effects of corrosive conditions on the physical and mechanical properties of concrete produced in cold weather. 30% calcium nitrate and 5% hydroxyethylaminemixture (HEA) were used as additives ...
Investigation of freeze-thaw effects on mechanical properties of fiber reinforced cement mortars
(Elsevier Sci Ltd, 2014)
Fibers are used for improving some properties of conventional concrete (which is a brittle material) such as tensile strength, abrasion resistance, absorption and crack control. This study investigates the usability of ...
Strength and ultrasonic properties of cemented paste backfill
(Elsevier, 2014)
This paper presents the strength (UCS) and ultrasonic pulse velocity (UPV) properties of cemented paste backfill (CPB) produced from two different mill tailings (Tailings T1 and T2). A total of 240 CPB samples with diameter ...
Effect of different surface oxidation treatments on structural, mechanical and tribological properties of ultrafine-grained titanium
(Elsevier Science Sa, 2014)
Four different surface oxidation treatments, so-called, anodizing oxidation (AO), micro-arc oxidation (MAO), plasma oxidation (PO) and thermal oxidation (TO), were applied to ultrafine-grained (UFG) pure titanium produced ...
A New Approach Stereo Based Palmprint Extraction in Unrestricted Postures
(IEEE, 2014)
Regarding the palms recognition system studies, despite achieving a high success rate, hygiene problems in systems with contact and problems arising from changes in the alignment of the hand pose in non-contact ones have ...
ISIL İŞLEMİN AKIMSIZ Nİ-B KAPLANAN SAF TİTANYUMUN YAPISINA ETKİSİ
(2014)
Saf titanyum, düşük ağırlığı nedeniyle sanayide çok geniş kullanım potansiyeline sahiptir, fakat diğer taraftan düşük sertlik ve aşınma direnci, yüksek sıcaklıklarda zayıf korozyon direnci ve yüksek maliyet gibi taşıdığı ...
Is the combined use of insulin resistance indices, including adipokines, more reliable in metabolic syndrome?
(2014)
Background/aim: To determine the levels of adipokines (leptin, adiponectin, resistin, and visfatin) and the indices of insulin sensitivity/ resistance, and to examine the relationship among them in patients with metabolic ...
