Time synchronization in measurement networks
Kaya, Zahit Evren; Bilgen, Semih; Department of Electrical and Electronics Engineering (2010)
AMR (Automatic Measurement Reading) applications usually require measurement data to be collected from separate locations. In order to combine the data retrieved from separate sources into a meaningful result, all sources should share a common time sense. Therefore, it is necessary to implement a synchronization scheme in measurement networks. In this thesis, a synchronization scheme which combines GPS (Global Positioning System) and two high accuracy WSN (Wireless Sensor Network) time synchronization algor...

Time-frequency decorrelating decision-feedback multiuser detector over fast-fading multipath channels for synchronous DS-CDMA systems
Ertug, O; Baykal, Buyurman (2001-03-23)
RAKE receivers suffer degradation in performance under fast fading due to errors in channel state estimation. The wide-sense stationary uncorrelated scatterer channel model lends itself to time-frequency canonical representation, and provides additional diversity in the frequency axis. Using the joint multipath-Doppler diversity model based on this canonical representation, we propose a nonlinear time-frequency decorrelating decision-feedback multiuser detector for synchronous CDMA which utilizes decisions ...
Time domain terahertz spectroscopy: construction of the setup and application in analysis of active pharmaceutical ingredients
Aytekin, Yusuf Samet; Esentürk, Okan; Department of Chemistry (2016)
The purpose of this thesis is to build a homemade Terahertz (THz) Time Domain Spectrometer and analysis of Active Pharmaceutical Ingredients (API) by using the built THz-TDS spectrometer. Several configurations of THz-TDS system were setup and tested in order to optimise experimental parameters. These set-ups can be grouped into two; antenna-antenna and antenna-crystal. In antenna-antenna systems, photoconductive antenna (PCA)and interdigital photoconductive antenna (iPCA) were employed and both were tried ...
Time scale extensions of a theorem of Wintner on systems with asymptotic equilibrium
Mert, R.; Zafer, Ağacık (Informa UK Limited, 2011-01-01)
Abstract We consider quasilinear dynamic systems of the form[image omitted]where is a time scale, and provide extensions of a theorem of Wintner on systems with asymptotic equilibrium to arbitrary time scales. More specifically, we give sufficient conditions for the asymptotic equilibrium of the above system in the sense that for any given constant vector c, there is a solution satisfying[image omitted] Our results are new for difference equations, q-difference equations and many other time scale systems ev...
