Trellis coding for spatial modulation [Uzaysal modulasyon i?çi?n kafes kodlama]
(2011)In this study by combining trellis coding with spatial modulation (SM) a new multiple-input multiple output (MIMO) communication scheme called trellis coded spatial modulation (TC-SM) is proposed. For uncorrelated Rayleigh ... -
True variable-depth milling
(Elsevier B.V., 2020)When tool wears during machining, cost of the process increases. Rapid tool wear leads to even further contributions to process cost and hence must be taken well care of. Among the many forms of tool wear, notch wear is ... -
Turkey - Romania subsea transmission cable investment: Time for reconsideration?
(2013)Transmission investment is important for integrating electricity markets operated by different countries/transmission system operators (TSOs). Turkey and Romania have proposed a transmission cable linking the transmission ... -
Turkish public preferences for energy
(Elsevier Science, 2018)Public concern over energy supplies prices sustainability and efficiency has emerged as a major issue around the world. Yet most of what we know regarding public opinion on energy comes from North America and Europe. This ... -
UNIFAC application to water-1-propanol-n-amyl alcohol and n-amyl acetate ternaries
(2006)Liquid-liquid equilibrium (LLE) data for water-1-propanol-n-amyl alcohol and water-1-propanol-n-amyl acetate ternaries were measured at T=298.2 K. The UNIFAC model was used to correlate the experimental data. A comparison ... -
