Failure and circuit upset of electronic equipment due to transients is a problem now and is one which has promise of becoming more of a problem in the future as trends continue toward miniaturization and circuit complexity. Protection methods are used more or less extensively and often haphazardly. At present, there does not appear to be a clear approach toward achieving compatibility between t...

Trustworthy operation of industrial control systems (ICS) depends on secure code execution on the embedded programmable logic controllers (PLCs). The controllers monitor and control the underlying physical plants such as electric power grids and continuously report back the system status to human operators. We present HARVEY, 1 a PLC rootkit that implements a physics-aware stealthy attack again...

The development of signal transmitting environment for multimodal traffic control will enhance the integration of emergency and specialized transport routing tools in usual traffic control paradigms it is one of the opportunities offered by modern intelligent traffic control systems. The improvement of effective electric power use in public transport system is an advantage of Intelligent Transp...

Outdoor high-voltage equipment is exposed to moisture, rain and pollution. Water droplets on insulators influence negatively the material-aging process. A numerical procedure is presented which simulates the droplet behavior in a strong electric field. It consists in an iteration over an electric and a mechanical sub-problem to solve a coupled system of boundary value problems on the free domai...

The paper presents a general theoretical solution oftheinduction motor speed-fluxdirect vector control, which is based on the second Lyapunov method application. structure of direct control algorithm involves use anyasymptotic flux observer with exponential stability properties. Suchapproach led to improvement system robustness A constructive procedure for designof correction termsof rotor prop...

In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...

The study bases its analysis on projections that the electric grid will rely more on renewable energy and non-emitting power generation. It corroborates earlier findings that a decarbonizing grid accommodating a fleet of electric vehicles would reduce emissions relative to scenarios in which transportation, industrial and other fleets continue to rely primarily on petroleum fuels. With the wide...
