Collision Avoidance at Sea with Particular Reference to Rudder Speed

Decision support system for collision avoidance at sea

The paper presents design and realization of computer decision support system in collision situations of passage with greater quantity of met objects. The system was implemented into the real ship electro-navigational system onboard research and training ship m/v HORYZONT II. The radar system with Automatic Radar Plotting Aid constitutes a source of input data for algorithm determining safe tra...

Time-to-collision and Collision Avoidance Systems

In research on Traffic Conflicts Techniques, Time-To-Collision (TTC) has proven to be an effective measure for rating the severity of traffic conflicts and for discriminating critical from normal behaviour. The results of several studies point to the direct use of TTC as a cue for decision-making in traffic. The current development of driver support systems based on the application of modern te...

Constrictive pericarditis with particular reference to etiology.

Phagocytosis, with particular reference to encapsulated bacteria.

The phagocytic cells of the mammalian host provide a remarkable defense against a wide variety of bacteria, fungi, and protozoa. Whether they play a protective role in infections caused by viruses and rickettsiae is at present a matter of conjecture. The discovery of "pinocytosis" (Gey, 1954), however, and recent observations relating to bacterial endotoxins (Berthrong and Cluff, 1953; Braude e...

Investigation of Dual Fuel Diesel Engine With Particular Reference to Engine Cycle Model

In order to use gaseous fuels in Diesel Engines, Dual-Fuel Diesel Engine (D. F. D. E) the pilot injection approach is chosen. To predict its performance, an engine cycle model, based on limited-pressure Diesel cycle, is constructed. The model predicts D. F. D. E performance with LPG, and CNG gases. Comparing with pure Diesel engine, by increasing gas proportion in dual-fuel, indicated power and...
