    In this paper author introduces problem of the reduction of diagnostic information in evolution condition machine for estimating state prognosis algorithms which are the basis for determining conclusion rules for estimating the next machine operation term and for state genesis which is the basis for rules creating of machine state estimation in the past. Automation of the investigation system of the evolution of the technical systems machines condition in which diagnosing distinguishes itself of prognose of the state and the genesis of the state requires the qualifications of the gathering of diagnostic parameters describing the change of the condition of the machine during exploitation. The results of investigations connected with the implementation of the procedures of monitoring the technical machine engines condition and their investigation for the chosen arrangements of mechanical vehicles were introduce

    Through defining Water Traffic Black Spot and analyzing the advantages and disadvantages of identification methods of Road Traffic Black Spot, then choosing Quality Control Method to recognize water area of intensive traffic accidents and applying integrated influential intensity of accident rate based on Systematical Clustering Algorithm into defining the boundary of the area, an effective evaluation method of black spot identification that is established, which lays a foundation for the subsequent evaluation work

    This paper studies the performance of pattern matching algorithms with the goal of the detection and tracking of vessel targets in maritime radar images. We compare different methods using a database which consists of radar images from two different manufactures. The data covers a timespan of roughly 4 hours with a one second time resolution. The performance of 3 template matching and 5 feature detector algorithms is tested and the most suitable algorithm is chosen for further optimizations. These optimizations are based on the properties of the radar images and the properties of the radar target

    Paper presents basic information on the Constant False Alarm Rate (CFAR) algorithms and assessment of their practical efficiency in maritime FM-CW radar. Experimental research comprised qualitative assessment of the different CFAR algorithms done by the comparison of radar video signals presented by installed in the Gdynia Maritime University FM-CW radar type CRM-203 utilised these algorithms and pulse radars with digital (Raytheon Pathfinder MK2 and NSC 34) and analogue (Racal Decca AC 1690) display units

    Increasing accuracy of weather forecasts for ocean areas (wave factors, limits of ice), development of communication means, receiving and computations of navigational and weather information (satellite communication, computer programming) as well as development of theoretical basics of optimization and decision making process permit operational computations of optimal routes for ships on the oceans. Using dynamical programming, route selection is made objectively, taking into account dynamical changing weather conditions, ship characteristics and assumed optimization criteria. For computations different types of algorithms may be used: from graph theory, evolutionary algorithms based on genetic algorithms as well as isochrone ones. Following an example of results of ships voyages recommended by Polish Steamship Company routing centre, 3% of time voyage saving in comparison with seasonal voyages were obtained.
