Opis:
The research was carried out to determine the effect of different irrigation water requirements of different irrigation levels (mm), on the evapotranspiration seed yield (kg da-1) with vegetative and generative properties of two cotton types (drought tolerant, BA 525) and (drought susceptible, Lydia), in the Eastern Mediterranean region (Turkey). Drought or water deficit stress elicits many different phenological responses in plants. The study of vegetative features included the fresh and dry weight of plant (g), leaf area (cm2 ), number of leaves (number plant-1), number of fruit branches (number plant-1), number of bud formation (number plant-1) and number of node (number plant-1).This result indicates that water stress in plants limit the phenological development significantly and the average of all measurements made after flowering has been observed to decrease.

Opis:
The collision risk is one of the major reasons threaten safety at sea. The Collision Regulations (COLREGs) is the essential international arrangement which regulates the rules of the roads at sea. Being also a legal document, the language of the COLREGs is not so apparent for the end users (navigators) and this cause some misunderstandings and ambiguity. Many discussions on COLREGs have continued since its first submission related to its application. It seems unlikely to make a radical change on COLREGs even on its manner of introduction. So it would be better to improve new manners to ensure the effective use of COLREGs in particular in the field of education and training. It is aimed to review the existing studies on COLREGs and recent improvements in the maritime education, and investigate applicable and reliable solutions to reduce the negative impacts experienced during the application of the COLREGs.

Opis:
This study aims to reduce roll motion of a fishing boat which arises from disturbing hydrodynamic effects by means of fin roll stabilizer. It is assured that roll motion with nonlinear damping and restoring moment coefficients are down to the desired level through classical PID and modified PID algorithms. At the time of sailing, stability, a very important concept, was examined using Lyapunov direct method taking initial conditions into consideration, and it was noted that the system was generally stable. In addition, NACA 0015 model was used for the fin roll stabilizer, and flow analysis was carried out with Computational Fluid Dynamics (CFD) method. In the simulation results, when the same gains were used, modified PID controller algorithms were relatively more effective compared to PID in the fin roll stabilizer system.
