Researchers demonstrate a way to shuttle photons between modules of quantum processor that can detect and correct communication losses.

We investigate the relative computational powers of a mesh with static buses and a mesh with unidirectional wrap-mounds. A mesh with unidirectional wraparounds is a torus with the restriction that any wraparoundlink of the architecture can only transmit data in one of the two directions at any clock tick. We show that the problem of packet routing can be solved as efficiently on a linear array ...

This paper proposes an online measurement-based method for n-1 voltage stability assessment on a load area by means of an equivalent system of N+1 buses introduced by ref. [1] to represent N boundary buses of the load area and the external system. This method utilizes real-time synchro-phasor measurements on N boundary buses and online state estimation on the load area to analyze n-1 sensitivit...

Additional energy source of hybrid electric buses comprises new control tasks. One of the main challenges of hybrid electric buses is the integrated control between traction motor and brakes, associated with which is the problem of switching traction motor and brakes. Existing control techniques only provide a result of frequent switch and jerky ride. In this paper, we propose a control strateg...

Giving priority to buses at traffic intersections is a common practice in busy urban areas. Benefit for buses results from reduction of their journey times and improving their service reliability. However the negative impacts of such priorities for other intersection user’s e.g. individual traffic may exceed the buses benefits. In the paper two-level dynamic intelligent traffic control feedback...

Bus schedules cannot be easily maintained on busy lines with short headways: Experience shows that buses offering this type of service usually arrive irregularly at their stops, often in bunches. Although transit agencies build slack into their schedules to alleviate this problem − if necessary holding buses at control points to stay on schedule − their attempts often fail because practical amo...

Networks in the area of factory automation, named field-buses, have been developed to fulfill real-time requirements. However, they can only cover areas such as factory halls or buildings. This paper describes a model for a internetworking unit connecting field-buses via ATM networks, in order to break these limits. A remote bridge is used to span longer distances between field-bus components i...

The high data-rate communication channels represent one of the most power-aware design problem, trying to decrease energy consumption maintain acceptable some other performance constraints. In this context, the bus-switch mechanism represents a novel and efficient bus encoding approach for low-power data off-chip buses. It is based on tentatively encoding, clustering, reordering and encoding a ...

In this paper, Integer Programming based methodology is presented for the optimal placement of Phasor Measurement Unit (PMU) that minimizes the cost of installation and provide the entire power system observability. The concepts of zero injection buses are used in this paper for further reduction in number of PMUs. Integer Programming may produce multiple results if neighboring buses to zero in...
