Advancement of the motor vehicle and its production methods is analyzed as a process of technological change. In a broader context, motor vehicles evolved as an integral component of road transportation through a series of interlaced substitutions of old by new technologies. Building on a large number of studies that described technological substitution processes, first it is shown how new ener...

The last decade has witnessed tremendous progress in the development of marine technologies that provide scientists with advanced equipment and methods for ocean exploration and exploitation. Recent advances in marine robotics, sensors, computers, communications, and information systems are being applied to develop sophisticated technologies that will lead to safer, faster, and far more efficie...

The purpose of this paper is to present a fast, economical and practical method for mathematical modeling of aerodynamic characteristics of rectangular wing-in-ground effect (WIG). Reynolds averaged Navier-Stokes (RANS) equations were converted to Bernoulli equation by reasonable assumptions. Also Helmbold's equation was developed for calculation of the slope of wing lift coefficient in ground ...

In-situ visual observations of marine organisms is crucial to developing behavioural understandings and their relations surrounding ecosystem. Typically, these are collected via divers, tags, remotely-operated or human-piloted vehicles. Recently, however, autonomous underwater vehicles equipped with cameras embedded computers GPU capabilities being developed for a variety applications, in parti...

Motivations and general objectives: The possibility of employment of teams of UAVs (Unmanned Aerial Vehicles) within patrolling missions to be performed on the sea surface is currently receiving an increasing attention, by part of the scientific community, as they can be employed for the security and protection of marine areas, as well as humanitarian search and rescue reasons. The structure of...
