Science teaching in primary education in turkey based on constructivism and the problems which are encountered in practice
(Int Inst Informatics & Systemics, 2007)
Constructivism has been increasingly spreading in the educational systems of the developing countries. Because, there is strong evidence suggesting that constructivist applications are one of the ways to make students ...
Two Examples on Urban Renewal in Eskisehir
(Springer International Publishing Ag, 2018)
This study explores architectural and interior design features of the residential housing projects built in the Eskisehir Tepebasi region along the 1st and 2nd Ismet Inonu Avenues, and focuses on the rapid transition that ...
Design optimization of piezoelectric composite transducer using finite element method
(Trans Tech Publications LTD, 2002)
The effect of size on the performance of the cymbal transducer was investigated by using experimental and computational methods. Cymbal transducers were fabricated with steel endcap materials and piezoelectric ceramic, ...
IFVD-based large intermixing selectivity window process for high power laser diodes
(Spie-Int Soc Optical Engineering, 2018)
Catastrophic optical mirror damage (COMD) is a key issue in semiconductor lasers and it is initiated by facet heating because of optical absorption. To reduce optical absorption, the most promising method is to form ...
Semiconductor shallow impurity level transitions for terahertz generation and detection
(Optical Society of America (OSA), 2014)

Distributions of Wind Speed at Different Heights
(IEEE, 2016)
In this study, the parameters of different distributions such as the Weibull, Rayleigh, Lognormal, Gamma and Generalized Gamma, which are used for modelling wind speed, at the different heights 10 and 30 m, have been ...
Broadband asymmetric quantum-well infrared photodetector in Long-Wavelength Infrared Range (LWIR)
(2007)
A theoretical investigation of a GaAs-AlGaAs infrared detector consisting of three asymmetric quantum wells is presented. Each quantum well is sensitive to yield absorption and a photoresponse at peak wavelengths of 8 µm, ...
Estimation Method Based on MinMaxEnt Distribution for Missing Value in Time Series
(World Scientific Publ Co Pte LTD, 2009)
In this study, MinMaxEnt distribution out of Generalized Entropy Optimization Distributions with moment functions and moment values dependent on parameter are introduced. MaxEnt distribution for observed time series is ...
Determination of oxalate ion in bayer liquor using electrochemical method
(2011)
The Bayer process can be summarized as the digestion of bauxite with caustic liquor and the subsequent precipitation of hydrated alumina [1]. Most bauxite contains organic compounds in various amounts. Depending upon the ...
Spontaneously -made paintings and the form created in the potters wheel
(2004)
Potters wheel tradition dates back to 7000 years B.C. by the invention of potters wheel. In the early days of potters wheel tradition, besides terracotta pieces, polished pieces as well as slipped pieces were made. While ...
