This research work presents the adoption of proposed displacement based finite element model so-called nodal exact finite element to solve dynamic response of axially loaded pile. The pile is assumed to be circular cross section embedded in elastic soil. The shape functions satisfy homogeneous differential equation of uniform elasto-dynamic bar was constructed. The stiffness and mass matrices for axially loaded pile are then formulated using energy principle, incorporate with proposed shape function. The dynamic response parameters, such as dynamic pile-head stiffness and damping of pile's axial vibration were computed from proposed finite element model by iterative procedure. Illustrative examples show fairly accurate results and demonstrate an effectiveness of proposed finite element compared with available analytical solutions from literatures.

The recent Kunming-Montreal Global Biodiversity Framework (GBF) sets ambitious goals but no clear pathway for how zero loss of important biodiversity areas and halting human-induced extinction of threatened species will be achieved. We assembled a multi-taxa tracking dataset (11 million geopositions from 15,845 tracked individuals across 121 species) to provide a global assessment of space use of highly mobile marine megafauna, showing that 63% of the area that they cover is used 80% of the time as important migratory corridors or residence areas. The GBF 30% threshold (Target 3) will be insufficient for marine megafauna's effective conservation, leaving important areas exposed to major anthropogenic threats. Coupling area protection with mitigation strategies (e.g., fishing regulation, wildlife-traffic separation) will be essential to reach international goals and conserve biodiversity.

Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this gap, we created the Worldwide Soundscapes project, a collaborative network and growing database comprising metadata from 416 datasets across all realms (terrestrial, marine, freshwater and subterranean). Location Worldwide, 12,343 sites, all ecosystem types. Time Period 1991 to present. Major Taxa Studied All soniferous taxa. Methods We synthesise sampling coverage across spatial, temporal and ecological scales using metadata describing sampling locations, deployment schedules, focal taxa and audio recording parameters. We explore global trends in biological, anthropogenic and geophysical sounds based on 168 selected recordings from 12 ecosystems across all realms. Results Terrestrial sampling is spatially denser (46 sites per million square kilometre—Mkm 2 ) than aquatic sampling (0.3 and 1.8 sites/Mkm 2 in oceans and fresh water) with only two subterranean datasets. Although diel and lunar cycles are well sampled across realms, only marine datasets (55%) comprehensively sample all seasons. Across the 12 ecosystems selected for exploring global acoustic trends, biological sounds showed contrasting diel patterns across ecosystems, declined with distance from the Equator, and were negatively correlated with anthropogenic sounds. Main Conclusions PAM can inform macroecological studies as well as global conservation and phenology syntheses, but representation can be improved by expanding terrestrial taxonomic scope, sampling coverage in the high seas and subterranean ecosystems, and spatio-temporal replication in freshwater habitats. Overall, this

A series of experiments of heating columns in a localized fire was conducted to comprehend effects of a water application on the thermal response of the columns exposed to surrounding fire. The objectives of this study are to measure and analyze the vertical distribution of incident heat flux on and temperature in a column from a localized fire in an actual scale, including the effects of the sprinkler system. Specimens were designed to replicate a full-scale column (Size: 3.1 m high, 0.3 m wide, and 0.3 m deep) in buildings. The fire severity (heat release rate of fire source), water flow rate from a sprinkler head (80 L/min) in the experiments, as important parameters in a localized fire, were determined to demonstrate sever or typical conditions in the experimental capacity, respectively. As a result, indicated value of heat flux meter on the column and temperatures of wall surface covered with galvanized steel sheets decreased immediately after the sprinkler system was activated. After the indicated value of heat flux meter and temperature maintained constant values for a while (transition state), these values decreased again to another constant level (steady state). The heat flux reduced 13~23 kW/m2 by sprinkler system in transition state as the result of calculating the heat balance of wall surface (galvanized steel sheet). © 2018 Japan Association for Fire Science and engineering.

This study proposed a correction procedure for field observation data obtained by a three-dimensional ultrasonic anemometer. First, wind tunnel experiments were carried out in order to evaluate directional characteristics of the anemometer. Then, by using the experimental results, a correction table was developed which is used for correcting raw observation data. The effectiveness of the correction procedure was verified by applying it to the past field observation data obtained close to a building. From the comparison between raw and corrected data, it was found that the proposed procedure is effective for the mean vertical wind direction of larger than 30 degrees or smaller than -30 degrees.

Dependence of Short-Channel Effects on Semiconductor Bandgap in Tunnel Field-Effect Transistors

引用

Journal of Physics: Conference Series 2018年第1期1034卷

作者： Nguyen Dang Chien Chun-Hsing Shih Hung-Jin Teng Cong-Kha Pham Department for Management of Science and Technology Development Ton Duc Thang University Ho Chi Minh City Viet Nam Faculty of Electrical & Electronics Engineering Ton Duc Thang University Ho Chi Minh City Viet Nam Department of Electrical Engineering National Chi Nan University Nantou 54561 Taiwan Institute of Electronics Engineering National Tsing Hua University Hsinchu 30013 Taiwan Department of Network Engineering and Informatics The University of Electro-Communications Tokyo 182-8585 Japan

Scaling down the bandgap is considered as an essential approach to enhance the performance of tunnel field-effect transistors (TFETs). Using two-dimensional simulations, this study examines the dependence of short-channel effects on the semiconductor bandgap in TFETs. It is shown that the short-channel effect is more severe with using lower bandgap materials although the supply voltage is scaled in parallel with the bandgap. For a given bandgap material, the short-channel effect can be well evaluated by the increase of drain-induced barrier thinning (DIBT) with decreasing the channel length. For different bandgap TFETs, however, their short-channel effects cannot be compared properly by comparing the DIBTs. Adequately considering the effect of bandgap on the TFET scalability is necessary in designing scaled integrated circuits.
