1.0 INTRODUCTION Accurate road location and condition information are of primary importance in road infrastructure management. Additionally, spatially accurate and up-to-date road networks are essential in ambulance and rescue dispatch in emergency situations. However, accurate road infrastructure databases do not exist for vast areas, particularly in areas with rapid expansion. Currently, the ...

We present a communication solution tailored specifically for DC microgrids (MGs) that exploits: (i) the communication potential residing in power electronic converters interfacing distributed generators to powerlines and (ii) the multiple access nature of the communication channel presented by powerlines. The communication is achieved by modulating the parameters of the primary control loop im...

The notion of MyType has been proposed to promote type-safe reuse of binary methods and recently extended to mutually recursive definitions. It is well known, however, that MyType does not match with subtyping well. In the current type systems, type safety is guaranteed at the expenses of subtyping, hence dynamic dispatch. In this article, we propose two mechanisms, namely, nonheritable methods...

Abstract: For logistics centers the disposition and dispatch of goods has reached a high standard of automation. However, the trucks and trailers bringing and taking the goods are driven manually. This can at least be improved for the non-public traffic in the scope of logistics centers by autonomous forward and backward motion control for standard transportation vehicles. By an experimental sy...

Many systems are designed to perform both planning and execution: they include a plan deliberation component to produce plans that are then dispatched to an execution component, or executive, which is responsible for the performance of the actions in the plan. When the plans have temporal constraints, dispatch may be non-trivial, and the system may include a distinct dispatcher, which is respon...

Traditional power networks have been carefully managed at operations centers to ensure adequate power supplies are maintained despite peaks and troughs in demand. Each section of the grid has an operations center that conducts and coordinates various functions including system monitoring, control, crew administration and dispatch. It has been regarded conventionally as “the brain” of the power ...

Depleting oil reserves and the growing concerns of global warming, have made it compulsory to seek alternative in form of environment friendly technologies like renewable energy sources. The advantage of hybrid power systems is the combination of the continuously available diesel power and locally available, pollution-free wind energy. With the Wind-Diesel hybrid power system, the annual diesel...

This paper presents findings on changes in bus running times, on-time performance, and excess passenger wait times following implementation of transit signal priority in select bus corridors in the Portland metropolitan region. Analysis of the effectiveness of transit signal priority is often undertaken using simulation techniques or empirical studies that are either limited in scope and/or dat...

According to the European Directive 2009/28/EC 1 , renewable energy systems (RES) enjoy preferential treatment in the electricity grid in so far as the secure operation of the power system permits. However, there will be times when it is not possible to accommodate all priority dispatch generation such as variable renewable generation (VRG) sources like wind and solar while maintaining the safe...

The idea that large-scale generating units will operate at marginal cost when given the ability to offer their power for sale in a uniform price auction is at best wishful thinking. In fact, both real and experimental data show that the more uncertainty a supplier faces (e.g., load uncertainty, uncertainty of other suppliers, etc.) the more they will try to increase their profits by submitting ...
