Predictions of added resistance and the effective power ships were made for varying barnacle fouling conditions. A series towing tests was carried out using flat plates covered with artificial barnacles. The designed to allow examination effects height percentage coverage on ships. drag coefficients roughness function values evaluated plates. conditions ships' frictional resistances predicted. Added diagrams then plotted these predictions, powering penalties calculated generated. results...

Uncertain differential equation is a kind of equations driven by Liu processes, many concepts stability for uncertain have been researched. This paper first presents concept convergence in inverse distribution an sequence, and then proposes equation. A sufficient condition proved being stable distribution. Moreover, some examples are given to illustrate the reasonability

Two sets of experiments were designed to study the digestion mechanism methanogens acclimated by two kinds carbon source, acetic acid and propionic acid. It was found that utilization a complex process, first changing into prior uptake microorganism. In addition, possible inhibition high concentration substrate also demonstrated in this paper using kinetic models. The behavior on methane fermentation acts when total volatile fatty (VFA) is up 3.6g/l, completely observed for VFA 8.8g/l....

The Array for Real-time Geostrophic Oceanography (Argo) program provides valuable data maritime research and rescue operations. This paper is based on Argo historical satellite observations, inverted sea surface submarine drift trajectories. A neural network method was developed to predict the position of buoys, improving target tracking emergency support capabilities. Based a deep learning framework using Simple Recurrent Unit (SRU), new Time–Space Feature Fusion Method an Attention...

Abstract Objective Vaginal microbiota evaluation is a methodology widely used in China to diagnose various vaginal inflammatory diseases. Although has many advantages, it time-consuming and requires highly skilled experienced operators. Here, we investigated six-index functional test that analyzed pH, hydrogen peroxide (H 2 O ), leukocyte esterase (LEU), sialidase (SNA), β-glucuronidase (GUS), acetylglucossidase (NAG), determined its diagnostic value by comparing with morphological tests of...

RFID systems require anti-collision procedures to enable a reader communicate simultaneously with multiple tags. In this paper, we propose new procedure which uses schedules coordinate tags transmit their IDs. These are generated by synthesizing the time slot selections of tags, and collided in current schedule arranged IDs different groups slots next schedule. Simulations conducted results show that can significantly improve performance for recognizing

The emergence of the grid has brought fundamental changes to collect and deal with information. This paper states evolution supply chain model features workflow as platform, studies on problems about management G-SCM technology supporting, tradition foundation analyses business process working mechanism planning workflow, purchasing manufacturing delivery returning flow, internal external integration workflow; workflow. Finally, it looks ahead prospects impact G-SCM. promotes E-SCM high...

Abstract In view of the important practical needs marine forecasting and production in Bohai Sea port, this paper constructs a regional high-resolution coupled model sea air waves to carry out 5-day forecasting. The resolution ocean wave models is higher than 1km, inner layer grid atmospheric 3km. Compared with international advanced HYCOM, it found that simulation results high sub coupling are obviously better those its clearly shows flow field tidal current characteristics, which...

The resonant characteristics and the mode overlapping process of a three-gap coupled cavity output circuit had been discussed. Based on an X-band circuit, group delay characteristic working stability are simulated studied. results show that bandwidth 6.61% at 1.7dB fluctuation in may be obtained with three-mode each can stably operate bandwidth.

The effects of alloying elements Al, Cr, Si, V, Ni and Co on the Neel temperatures lattice parameters gamma -Fe-Mn alloys are analysed. Our experimental results fail to confirm universal relation between temperature parameter proposed by Adachi et al (1973). It is suggested that not a unique monotonic function for host alloys.
