Due to its excellent resistance traction and compression, wood is regularly used in furniture, window frames structures sealing of homes buildings. the anisotropy complexity material, properties vary depending on intrinsic anatomical characteristics external factors, such as species, moisture content, acting requests, among others. The Brazilian standard provides linear models for estimating co...

With the growing demand for service access and data transmission, security issues in optical fiber systems have become increasingly important subject of increased research. Physical layer secret key generation (PL-SKG), which leverages random but common channel properties at legitimate parties, has been shown to be a secure, low-cost, easily deployed technique as opposed computational-based cry...

The precision of human colour discrimination depends on the region of colour space in which measurements are made and on the direction in which the compared colours-the discriminanda-differ. Working in a MacLeod-Boynton chromaticity diagram scaled so that thresholds at the white point were equal for the two axes, we made measurements at reference points lying on lines that passed at 45° or -45°...

frost tolerance of winter wheat depends primarily on a strong vernalization requirement, delaying the transition to reproductive phase. the responses of four bread wheat cultivars (triticum aestivum l.) to low-temperatures were examined in controlled environment and field conditions. prolonged cold treatment accelerated the transition to reproductive development in winter wheats (cv. norstar an...

We propose and validate a novel experimental technique to measure two-point statistics of turbulent flows. It consists in spreading rigid fibers the flow tracking their position orientation time therefore been named ``Fiber Tracking Velocimetry'' (FTV). By choosing different fiber lengths, i.e. within inertial or dissipative range scales, turbulence fluctuations at selected lengthscale can be p...
