In this paper the parametric study is carried out to investigate the effect of number of cells in optimal cost of the non-prismatic reinforced concrete (RC) box girder bridges. The variables are geometry of cross section, tapered length, concrete strength and reinforcement of the box girders and slabs that are obtained using ECBO metaheuristic algorithm. The design is based on AASHTO standard s...

In this paper, we describe a new traitor tracing scheme which relies on Tardos’ collusion secure codes to achieve constant size ciphertexts. Our scheme is also equipped with a black-box tracing procedure against pirates that are allowed to decrypt with some (possibly high) error rate while keeping the decoders of the lowest possible size when using collusion secure codes, namely of size proport...

The Black-Box Hypothesis, introduced by Barak et al. [BGI12], states that any property of boolean functions decided efficiently (e.g., in BPP) with inputs represented by circuits can also be decided efficiently in the black-box setting, where an algorithm is given an oracle access to the input function and an upper bound on its circuit size. If this hypothesis is true, then P 6= NP. We focus on...

The low-voltage metering box is a critical piece of equipment in the power supply system. automated inspection boxes important their production, transportation, installation, operation and maintenance. In this work, an type identification size measurement method for based on RGB-D images proposed. components, including door shell window, connection terminal block, compartment cabinet, are segme...

In [eprint.iacr.org/2012/663] method of virtual isomorphisms of ciphers was applied for differential/linear cryptanalysis of AES. It was shown that AES seems to be weak against those attacks. That result can be generalized to AES-like ciphers, which diffusion map is a block matrix, and its block size is the same as the S-box size. S-box is possibly weak if it is affine equivalent to a substitut...

Classification of Partial discharge (PD) patterns is an important tool to determine the sources of the PD. Also the features that specify of the patterns can be used monitor the condition of the electrical insulation. A PD patterns classification approach of artificial partial discharge sources by using neural networks is proposed in this paper. The classification process was based on features ...
