The State of Rio Grande do Sul (RS) is the largest producer of oat in Brazil with the aid of consolidated breeding programs, which are constantly releasing new cultivars. The main objectives of this study were to: 1) evaluate the annual genetic progress in grain yield and hectoliter weight of the oat cultivars in RS, with and without fungicide use on aerial parts of plants; and 2) evaluate the ...

The effects of friction stir processing (FSP) on the microstructure and mechanical properties of aluminum powder metallurgy (PM) parts was investigated. PM parts were then subjected to FSP at advancing speeds (v) of 40-200 mm/min and tool rotational speeds (ω) of 800-1600 rpm. Microhardness (HV) and tensile tests at room temperature were used to evaluate the mechanical properties of the frictio...

Non-linear feedback shift registers are widely used in lightweight cryptographic primitives. For such constructions we propose a general analysis technique based on differential cryptanalysis. The essential idea is to identify conditions on the internal state to obtain a deterministic differential characteristic for a large number of rounds. Depending on whether these conditions involve public ...

In this paper, we propose a method for speeding-up Digital Signal Processing applications by partitioning them between the reconfigurable hardware blocks of different granularity and mapping critical parts of applications on coarse-grain reconfigurable hardware. The reconfigurable hardware blocks are embedded in a heterogeneous reconfigurable system architecture. The fine-grain part is implemen...

The paper examines the relationship between China's grain trade and domestic grain economy through an institutional perspective. It reveals that China's grain imports have been primarily necessitated by filling the physical gap between domestic grain demand and supply. Due to the special institutional background under which the domestic grain economy segmented into two relatively independent pa...
