Site amplification factors at period ranges of 0.1-0.2, 0.2-0.3, 0.3-0.5, 0.5-1, 1-2, and 2-10 s were determined for 27 stations of KiKnet and K-NET in and around the source area of the 2008 Iwate-Miyagi Nairiku earthquake. The ratio of the geometric mean values of the two maximum horizontal amplitudes of acceleration and velocity at the uphole to that at the downhole is considered as the ampli...

We survey some recent results due to myself, Nicola Pace and Gábor P. Nagy. A dual k-net of order n in the finite projective plane PG(2, q) over the finite field GF (q) consists of a k ≥ 3 pairwise disjoint point-sets (components), each of size n, such that every line meeting two distinct components meets each component in precisely one point. Dual k-nets are truly combinatorial objects; nevert...

Accurate spatial information of agricultural fields is important for providing actionable to farmers, managers, and policymakers. On the other hand, automated detection field boundaries a challenging task due their small size, irregular shape use mixed-cropping systems making vaguely defined. In this paper, we propose strategy boundary based on fully convolutional network architecture called Re...

We aimed to develop alternative fishing gear for catching the common octopus, to decrease the use of bait and operating costs in comparison to commercial net pots. A tubular-type pot was designed, and behavioral responses of the common octopus were experimentally monitored in tank and replicated 10 times to compare fishing performances between 300 experimental and 300 commercial net pots in the...

Soil nitrogen (N) processes and inorganic N availability are closely coupled with ecosystem productivity and various ecological processes. Spatio-temporal variations and environmental effects on net N transformation rates and inorganic N concentrations in bulk soil and ion exchange resin were examined in an upland pine forest (UPF) and a bottomland alder forest (BAF), which were expected to hav...

In the present article, we revisit question of structural characteristics and building methods two most famous Hungarian Late-Gothic net vaults, nave vault Franciscan Church Szeged-Alsóváros Reformed Nyírbátor. Based on data gathered by laser-scanning buildings, geometric system as opposed to former state research, differ significantly from each other. While rib webbing have features characteri...

This paper presents an application of neural networks operating on multimodal 3D data (3D point cloud, RGB, thermal) to effectively and precisely segment human hands objects held in hand realize a safe human–robot object handover. We discuss the problems encountered building sensor system, while focus is calibration alignment set cameras including thermal, NIR cameras. propose use copper–plasti...
