Underwater channel modeling for sonar applications
Epçaçan, Erdal; Çiloğlu, Tolga; Department of Electrical and Electronics Engineering (2011)
Underwater acoustic channel models have been studied in the context of communication and sonar applications. Acoustic propagation channel in an underwater environment exhibits multipath, time-variability and Doppler e ects. In this thesis, multipath fading channel models, underwater physical properties and sound propagation characteristics are studied. An underwater channel model for sonar applications is proposed. In the proposed model, the physical characteristics of underwater environment are considered ...
Underwater gliders: modeling, control and simulation studies
Gören, Semih; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2016)
This thesis includes mathematical model, navigation, controller design and guidance of the underwater gliders. Firstly, the mathematical model of the underwater glider is obtained with external forces and moments. The hydrodynamic coefficients are obtained by using the strip theory and Missile DATCOM Simulation Program. For navigation, optimal state estimator Kalman filter is implemented to find the position and the linear velocities of the underwater glider. The controllers are designed according to the li...

Acoustical identification of the concentration layer of a copepod species, Calanus euxinus
Mutlu, E (2003-03-01)
Swimming trajectories of Calanus euxinus Hulsemann in the Black Sea were studied using an echosounder at 120 and 200 kHz. C. euxinus were acoustically discriminated with respect to vertical migration and swimming speed, according to dissolved oxygen (DO) concentration and the timing of migrations. Species became torpid in water with DO values < 0.5 mg l(-1). The time spent swimming under DO conditions between 2 and 5 mg l(-1) was insignificant, and varied greatly from the 10% to 25% of total time spent swim...

Coasts are sensitive and dynamic areas against natural influences such as waves, winds, currents, and tides. Pressure of human activities also accelerate the change of coasts. Climate change and global sea level rise are other factors affecting the coasts. Therefore, the identification and protection of coasts, which are important in terms of socio-economically and natural environment, becomes an important issue. One of the main purposes of this study is to classify Mersin and İskenderun bays coasts accordi...
