Operating Vehicles’ Speed Prediction Models [PDF]

open access: yesPromet (Zagreb)
Vehicle speed is one of the main factors that influence the occurrence and severity of the consequences of road traffic accidents. Operating speed can be defined, among other things, as the actual speed at which the largest number of road users drive in ...

A Unified Mathematical Model for High Speed Hybrid (Air and Water-borne) Vehicles. [PDF]

open access: yes, 2007
During the last two decades, the interest in civil and military high speed marine vehicles has lead to several new configurations. Some of them exploit a combination of aerodynamic and hydrodynamic forces to sustain part of the weight of the craft ...

Globally convergent algorithms for dc operating point analysis of nonlinear circuits [PDF]

open access: yes, 2003
An important objective in the analysis of an electronic circuit is to find its quiescent or DC operating point. This is the starting point for performing other types of circuit analysis.

Design Consistency Index for Two-lane Roads based on Continuous Speed Profiles

open access: yesPromet (Zagreb), 2018
It is well known that road accidents tend to be more frequent in locations where a sudden change in road characteristics violates the driver's expectations.

Operating speed as a key factor in studying the driver behaviour in a rural context

open access: yesTransport, 2016
The research aims to explore the effects of geometric road features on driver speed behaviour in order to identify unsafe road segments where high reductions in speed between successive road elements occur.

Freeway safety management: case studies in Italy

open access: yesTransport, 2012
Road safety has since become one of the major factors for a description of the state traffic system and crashes are often due to bad made decisions by drivers in environments created by engineers.

Generic maximum power point tracking controller for small-scale wind turbines [PDF]

open access: yes, 2012
The output power of a wind energy conversion system (WECS) is maximized if the wind rotor is driven at an optimal rotational speed for a particular wind speed. To achieve this, a Maximum Power Point Tracking (MPPT) controller is usually used.
