Since phasor measurement unit (PMU) was invented, there has been growing interest in developing methodologies for finding the minimum number of PMUs complete system observability. The methods PMU placement must consider fact that network topology may change when power is affected by a contingency event. Therefore problem can be stated as observability considering failure probability transmission lines. In this study, authors propose new reliability‐ based model constrained placement....
Since phasor measurement units (PMU) were invented, there has been growing interest in developing methodologies for improving monitoring, protection and control of power systems real time. In this study, the authors propose a new methodology, based on graph modelling, to identify coherent groups generators real‐time fashion. The are identified with instantaneous values measured from system through PMUs, methodology needs neither setting number desired nor defining threshold value since it is...
In this study, a collision avoidance system is presented, based on the information provided by laser‐scanner sensor, in which two actions could be taken case of danger. Firstly, tries to stop vehicle order avoid accident. If reduction speed not sufficiently effective, control takes steering and deviates vehicle's trajectory escape from hazardous situation. The evaluates situation decides most appropriate action each considering free areas surroundings using detailed digital map. This has...
The use of drones is nowadays an extended procedure in the surveillance and combat missions armies different NATO countries. concept drone a generalization so called unmanned vehicles, whose more usual unit Unmanned Aerial Vehicle (UAV). However, recent years civil autonomous vehicles technology has been to military sector that demands carry out ground with Ground Vehicles (UGV). These develop unstructured environments, usually off-road, must be able combining behaviors plus tele-operation...
Information and communication technologies are being massively applied in the automotive field as basis of new generation active safety systems. In this extensive technologies, vehicular communications will constitute core a large set advanced driving assistance systems for improving road well helping to reduce environmental impact transport. These currently under deployment, but their mandatory installation newly manufactured cars is foreseen next 5 years. This equipment enable Advanced...
In this paper graph theory is used to identify coherent groups of generators and locate PMUs for Inter-Area monitoring. Initially, the problem identifying presented as a graphical problem. Then, three clustering methods are implemented group generators. Finally, when electric network separated in regions, placement PMU based on centrality criteria proposed. This can be first stage implementation plan monitoring large power system. Dynamic simulations phasorial representation done with...
This paper presents the application of fault tree analysis to calculate probability failure a substation monitoring system based on branch phasor measurement units. Results are used in reliability-based model for contingency-constrained units (PMUs) placement find minimum number substations where PMUs must be located enhancing wide area reliability. The algorithm selects minimal monitor power under normal operation and most credible contingencies. Finally, four indexes will computed evaluate...
The accurate perception of the surroundings a vehicle has been subject study numerous automotive researchers for many years. Although several projects in this area have successfully completed, very few prototypes actually industrialized and installed mass produced cars. This indicates that these research efforts must continue order to improve present systems. Moreover, trend include communication systems vehicles extends potential transmitting their information via wireless other may be...
Many driver assistance systems require knowledge of the vehicle environment. As these are increasing in complexity and performance, this environment needs to be more complete reliable, so sensor fusion combining long, medium short range sensors is now being used. This paper analyzes feasibility using ultrasonic for low cost vehicle-positioning tracking lane adjacent host order identify free areas around provide information an automatic avoidance collision system that can perform autonomous...
Abstract The paper is of tutorial value. A theoretical treatment adaptive (online) identification issues reviewed side by for linear time‐delay systems (LTDSs) with state measurements and single‐input single‐output (SISO) LTDS output measurements. class parameter algorithms then presented SISO known unknown delays. An application the proposed to transient fuel in a port‐fuel‐injected internal combustion engine illustrated an experimental study. Copyright © 2008 John Wiley & Sons, Ltd.
Autonomous road vehicles are increasingly becoming more important and there several techniques sensors that being applied for vehicle control. This paper presents an alternative system maintaining the position of autonomous without adding additional elements to standard sensor architecture, by using a 3D laser scanner continuously detecting reference element in situations which GNSS receiver fails or provides accuracy below required level. Considering guidance variables accurately estimated...
Vehicle-to-X (V2X) communications allow real-time information sharing between vehicles and Roadside Units (RSUs). These kinds of technologies for the improvement road safety can be used in combination with other systems. Advanced Driver Assistance Systems (ADAS) are an example along V2X to improve performance enable Cooperative Systems. A key element vehicular is that transmitted through network always linked a GPS position related origin destination (GeoNetworking protocol) order adjust...

Along lines, illustrates an application developed to transient fuel in gasoline port injected (PFI)...
This paper explains why the reliability assessment of energy limited systems requires more detailed models for primary generating resources availability, internal and external dispatch customer demand than ones commonly used large power presents a methodology based on full sequential Monte Carlo simulation technique with AC flow their long term which can properly include these models. By means real example, it is shown how simplified modeling traditionally leads to pessimistic predictions if...
