Broadband asymmetric quantum-well infrared photodetector in long-wavelength infrared range (LWIR)
(IEEE, 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 pro, ...
BER performance of generalized multicarrier DS-CDMA system with blackman chip waveforms over Nakagami-m fading channels [Blackman kirmik dalgabiçiminin kullanildi?i genelleştirilmiş çoktaşiyicili DD-KBÇE sistemin Nakagami-m sönümlü kanallardaki BHO performansi]
(2008 IEEE 16th Signal Processing, Communication and Applications Conference, SIU, 2008)
Multicarrier direct sequence-code division multiple access (MC DS-CDMA) is a novel radio access scheme that combines time domain spreading and multicarrier modulation. However, MC DS-CDMA systems suffer strongly from the ...
Production of the ADD type Kaluza-Klein excitations at future e +e -, ep and pp colliders
(2007)
Possible production of ADD type Kaluza-Klein excitations are investigated at future high energy e +e -, ep and pp colliders. Discovery limits and signatures of such excitations are discussed at above colliders comparatively. ...
Copper recovery from the tailings of slag flotation by leaching and roasting
(2006)
The sulphuric acid and the hydrogen peroxide leaching and roasting with/without addition of NaCl and Na2SO4of tailings of Black Sea Copper Works Flotation Plant (in Turkey) were studied. The native copper, covellite, ...
Toe erosion induced landslides from şebinkarahisar (Giresun-Turkey): Part I
(2007)
This case study presented herein describes and analyses the results of the detailed surveys of landslides caused by toe erosion in Avutmus district of Sebinkarahisar (Giresun-Turkey), based on field and laboratory measurements, ...
Electrochemical investigation of pyrite floatability and hydrophobicity with Dithiophosphate and Fe-Ions
(2006)
This research was performed to elucidate the role of DTP and Fe ions on the hydrophobicity and floatability of pyrite in chemically controlled electrochemical conditions between 0-500 mV vs. SHE. Experimental works suggested ...
Dissolution of chalcopyrite concentrate by dichromate ions in sulphuric acid medium
(2006)
In this study, the leaching conditions of chalcopyrite (CuFeS2) concentrate enriched through flotation of Menka Corporation Cu-Pb-Zn complex ore in sulphuric acid medium under effect of potassium dichromate were investigated. ...
An investigation on the properties of nano TiB2 reinforced hot pressed B4C-SiC composites
(2nd International Congress on Ceramics, ICC 2008, 2008)
In this study, the effect of nano TiB2 addition on microstructural, physical and mechanical properties of the B4C-SiC powder composites were investigated after high energy milling and hot pressing. In the present work, ...
