Why narrow-kerf technologies are justifiable in modern sawmills?
PublikacjaAnaliza struktury kosztów w tartaku wykazuje, że największy wpływ na ich wartość mają koszty surowca. Przy występującej tendencji kurczenia się zasobów surowca należy dążyć do stosowania w tartakach materiałooszczędnych technologii, w których stosuje się cienkie piły. Przy prawidłowo prowadzonym procesie cięcia zapewniają one redukcję strat materiałowych i korzyści finansowe. Szczególnie wysokie zyski mogą być przy pozyskiwaniu...

Distributed protection against non-cooperative node behavior in multi-hop wireless networks
PublikacjaAn important security problem in today's distributed data networks is the prevention of non-cooperative behavior i.e., attacks consisting in the modification of standard node operation to gain unfair advantage over other system nodes. Such a behavior is currently feasible in many types of computer networks whose communication protocols are designed to maximize the network performance assuming full node cooperation. Moreover, it...

Compact 4 × 4 butler matrix with non‐standard phase differences for IoT applications
PublikacjaButler matrices represent a popular class of feeding networks for antenna arrays. Large dimensions and the lack of flexibility in terms of achievable output phase difference make conventional Butler structures of limited use for modern communication devices. In this work, a compact planar 4 × 4 matrix with non-standard relative phase shifts of –30º, 150º, –120º, and 60º has been proposed. The structure is designed to operate at...

Process arrival pattern aware algorithms for acceleration of scatter and gather operations
PublikacjaImbalanced process arrival patterns (PAPs) are ubiquitous in many parallel and distributed systems, especially in HPC ones. The collective operations, e.g. in MPI, are designed for equal process arrival times (PATs), and are not optimized for deviations in their appearance. We propose eight new PAP-aware algorithms for the scatter and gather operations. They are binomial or linear tree adaptations introducing additional process...
