Off-chip bus transitions are a major source of power dissipation for embedded systems. In this paper, new adaptive encoding schemes are proposed that significantly reduce transition activity on data and multiplexed address buses. These adaptive techniques are based on self-organizing lists to achieve reduction in transition activity by exploiting the spatial and temporal locality of the address...

With dramatic scaling in feature sizes, noise resilience is becoming one of the most important design parameters, similar to performance and energy efficiency. Noise resilience is particularly problematic in long on-chip buses of complex single chip systems such as on-chip multiprocessors. While one might opt to employ a very powerful error protection scheme, this may not be very energy efficie...

We give improved deterministic algorithms for permutation routing and sorting on meshes with row and column buses. Among our results, we obtain a fairly simple algorithm for permutation routing on two-dimensional meshes with buses that achieves a running time of n + o(n) and a queue size of 2. We also describe an algorithm for routing on r-dimensional networks with a running time of (2? 1=r)n+ ...

This paper proposes a new model of illumination variations of the object appearance, culled the geodesic illumination basis model. It calculates poseindependent illumination buses on a 30 model, and these buses are warped into view-dependent buses in any pose. We experimentally evaluate how many illumination samples and buses are necessary, and show that our model can compensate for any illumin...

We study nonlinear power systems consisting of generators, generator buses, and non-generator buses. First, looking at a generator and its bus’ variables jointly, we introduce a synchronization concept for a pair of such joint generators and buses. We show that this concept is related to graph symmetry. Next, we extend, in two ways, the synchronization from a pair to a partition of all generato...

Buses are the primary means of public transportation in the city of Rio de Janeiro, carrying around 100 million passengers every month. §Recently, real-time GPS coordinates of all operating public buses has been made publicly available – roughly 1 million GPS entries each captured each day. In an initial study, we observed that a substantial number of buses follow trajectories that do not follo...

In times past in a country far away, passengers on intercity buses were all assigned seat numbers, and the buses were always full. There were many casual people, and there were a few people who were real sticklers for the rules. This is where our problem begins. Adam is the first person to enter an n seat intercity bus, and, since he is a casual person, he takes a seat at random. Subsequently, ...

Acoustical noise produced by vehicular traffic depends on many parameters, including the geometry and the general features of the road. The presence of a conflicting point, i.e. an intersection, strongly affects and modifies the simulation strategy of noise in urban environments, that is usually performed with statistical models tuned on experimental data related to standard condition (free flo...

This paper proposes an application of evolutionary programming (EP) to reactive power planning (RPP) considering the highest load buses, instead of considering the randomly selected load buses to install the reactive power sources. The proposed approach has been used in the IEEE 30-bus system. Simulation results, compared with those obtained by using the previous method of RPP using EP, conside...

background and aim: digits are suitable materials for hearing assessment of wide range of patients including children and adults with various language abilities. single monosyllabic 1-10 digits in triplet formant have been used for measuring speech recognition threshold in signal-to-noise ratio. the purpose of this study was to determine signal-to-noise ratio (snr) needed for 50 percent correct...
