O Earnings Before Interest, Taxes and Amortization (EBITDA) é um indicador financeiro intensamente utilizado por empresas e pesquisadores, principalmente na mensuração avaliação de desempenho empreendimentos. objetivo, neste trabalho, consistiu em realizar levantamento sobre a produção científica que trata da utilização do EBITDA apresentar mapeamentos estrutura desse campo pesquisa. A análise ...

We study the asymptotic efficiency of indistinguishability obfuscation (iO) on two fronts: • Obfuscation size: Present constructions of indistinguishability obfuscation (iO) create obfuscated programs where the size of the obfuscated program is at least a multiplicative factor of security parameter larger than the size of the original program. In this work, we construct the first iO scheme for ...

Efficient ray tracing of subdivision surfaces is an important problem in production rendering, and for interactive applications in the near future. The current hardware trends for both CPUs and GPUs suggest that compute power is outpacing bandwidth. Despite this, current approaches for ray tracing subdivision surfaces favor geometry caches or full pre-tessellation. We demonstrate that directly ...

Theory presents two channels through which profit sharing can increase worker training. First, it directly increases training by alleviating hold-up problems and/or encouraging co-workers to provide training. Second, it indirectly increases training by reducing worker separation and increasing training investment’s amortization period. This paper provides the first attempt at separately identif...

For a linear function f , a vector x with small coefficients, and a vector y = f(x), we would like to be able to give a zero-knowledge proof for the knowledge of an x′ with small coefficients that satisfies f(x′) = y. This is a common scenario in lattice-based cryptography, and there is currently no satisfactory solution for this problem. All known protocols are built via the repetition of a ba...

The major principle of multicast communication is that each data packet sent from one source must reach all the receivers exactly as it originates from the source without any modification on the way. For information to be authentic there is the need to ensure that the information is from where they claim to come from and that security requirements are put in place. In multicast applications, wh...
