The coupled damage/plasticity model for meso-level which is ply-level in case of Uni-Directional (UD) Fiber Reinforced Polymers (FRPs) is implemented. The mathematical formulations, particularly the plasticity part, are discussed in a comprehensive manner. The plastic potential is defined in effective stress space and the damage evolution is based on the theory of irreversible thermodynamics. T...

Substitution boxes are important parts in many block and stream ciphers. The emergence of a range of crypto-attacks has led to the development of criteria for repelling such attacks. The non-linearity criterion provides some protection against wellknown attacks, such as linear cryptanalysis and differential cryptanalysis. The open problem is constructed by generating methods which will be rapid...

A Monte Carlo model based on signal-dependent charge sharing mechanism during charge collection has been developed to explain the non-linearity of the Photon Transfer Curve (PTC) in image sensors. The model is based on tracing of individual electrons generated by Poisson-distributed photons and describes the PTC non-linearity as a process with subPoisson variance, with excellent qualitative agr...

Temporal characteristics of individual segments are affected by various global and local factors, such as tempo, syllable structure or position of a segment within the word. This has been shown for many languages, but since the general trends may be language specific, the present study investigates such effects for Czech. The material included 28 natural phonotactically complex words spoken by ...

This paper presents an experimental and computational study of four deployable reflectors with collapsible edge stiffeners, to verify the differences in behavior that had been predicted in a previous theoretical study. The experimental models have different geometric configurations and are made of two different plastics. Both folding experiments and vibration tests in the fully deployed configu...

The paper presents operational characteristics of a small induction motor with the stator core made of amorphous laminations, supplied from mains or frequency inverter at 100 and 200 Hz. Calculations were performed using field-circuit and equivalent circuit approaches taking account of non-linearity and additional losses both in the core and in the windings. Data for mechanical losses, magnetis...

The paper deals with the problem of numerical simulation of contact between compliant gripping element and rigid object of handling. Compliant gripping element is represented with a rubber suction cap and the handling object is comprised by rigid plate. Contact is researched under various load conditions taking account to chosen material of suction cap that is characterized with nonlinear depen...

The topographic electroretinogram evoked by multi-focal exchange of black and white or red and green stimuli was analysed into linear and non-linear Wiener kernels. The first-order (temporally linear) response showed a biphasic waveform which inverted as the luminance ratio of the exchanged colours passed through unity (established both psychophysically and photometrically). A short latency non...
