We present a computational model to reconstruct ancestor trees of animals with sexual reproduction following the theoretical model presented in Phys. Rev. E 90, 022125 (2014). Through a recursive algorithm combined with a random number generator, it is possible to reproduce the number of ancestor for each generation and use it to constraint a maximum number of the following generation. This sim...

The classical, ubiquitous, predecessor problem is to construct a data structure for a set of integers that supports fast predecessor queries. Its generalization to weighted trees, a.k.a. the weighted ancestor problem, has been extensively explored and successfully reduced to the predecessor problem. It is known that any solution for both problems with an input set from a polynomially bounded un...

This paper presents our ongoing work on the analysis and optimization of cryptanalytic time-memory tradeoffs targeting the COPACOBANA architecture [KPP06] as platform for the precomputation/online phase.

Low latency, application, specific multipliers are required fo r m,any DSP algorithms. Tree multipliers are an obvious answer to this requirement. However, tree architectures have not been considered for automatic multiplier generation because they have been conszdered to be irregular. I n this paper, a recursive methodology f o r generating n-2 compressors (for n in the range 3 5 n 5 64) using...

An imbedded language system for the hyout of VLSI circuits is examined. It is shown that through the judicious use of this system, a large variety of circuits can be designed with circuit density and performance comparable to traditional full-custom design methods, but with design costs more comparable to semi-custom design methods, The high performance of this methodology is attributable to th...

Rio de Janeiro’s Integrated Command and Control Center (CICC-RJ ) has already seen duty in several large scale events which happened in town, some planned, others not. CICC-RJ is part of Rio de Janeiro state’s response to the Brazilian national government’s mandate to improve the state’s ability to anticipate and respond coherently to public safety events in the region. Its infrastructure is in...
