It is well-known that large amounts of data are collected and processed during the operation electric submersible pumps. To optimize work mining control center operators, it recommended to use an automated emergency prevention system. In this way, operators will be able receive timely information about possible equipment failures, which in its turn increase service life reduce operating costs f...

Floating offshore wind turbines (FOWTs) still face many challenges in improving platform stability. A fully submersible FOWT with inclined side columns is designed to tackle the current technical bottleneck of platform, combining structural characteristics semi-submersible and Spar platform. An integrated numerical model established considering coupled effect, hydrodynamic performance novel FOW...

A new species of the deep-sea spongicolid genus Spongicoloides Hansen, 1908 is described and illustrated based on material from the northwestern Pacific. Spongicoloides weijiaensissp. n. was found inside a hexactinellid sponge, Euplectella sp., sampled by the Chinese manned submersible "Jiaolong" at depths of 2279 m near the Weijia Guyot, in the Magellan Seamount Chain. The new species can be d...

In this paper we present results of the application of a Simultaneous Localisation and Map building (SLAM) algorithm to estimate the motion of a submersible vehicle. Scans obtained from an on-board sonar are processed to extract stable point features in the environment. These point features are then used to build up a map of the environment while simultaneously providing estimates of the vehicl...

In this study was observed the maintenance task of submersible pumps septic tanks installed in industrial bathrooms. This maintenance activity operators are exposed to various biological and ergonomic risks. This type of activity requires its great physical performers who are also subject to contact with human waste in the form of liquids, gases and solids. Besides the problems mentioned, are s...

This paper describes a feasibility study that is included with the research, development and testing of a micro communications sonobuoy deployable by Maritime Fixed wing Unmanned Aerial Vehicles (M-UAV) and rotor wing Quad Copters which are both currently being developed by the University of Adelaide. The micro communications sonobuoy is developed to act as a seamless communication relay betwee...

The Bujumbura meteorological station lies at the northern end of the lake (3.32° S, 29.32° E), while the Mbala station is situated 40 km from the southern end (8.85° S, 31.33° E). Both stations are part of the World Meteorological Organisation network. The lake temperature was measured with a CTD12+ instrument (accuracy ±0.01 °C) and an automatic ANDERAA thermistor string installed in the south...

A comparison of spectrophotometry and submersible fluorescence probe as methods for quantification of chlorophyll a content and phytoplankton diversity was performed in lake Gransjön, located in middle of Sweden.The values ranged from 2.49 μg/l to 7.91 μg/l, but did not correspond between the tested methods. Algae communities were examined via FluoroProbe and inverted microscopy technique. Ther...

A self-supported direct borohydride-hydrogen peroxide fuel cell system with internal manifolds and an auxiliary control unit is reported. The system, while operating under ambient conditions, delivers a peak power of 40 W with about 2 W to run the auxiliary control unit. A critical cause and effect analysis, on the data for single cells and stack, suggests the optimum concentrations of fuel and...

Agile manufacturing (AM) is a 21 century concept in manufacturing firm intended to improve the competitiveness of firms. Manufacturing process based on AM is characterized by customer-supplier integrated process for product design, manufacturing, marketing and support services. This needs decision-making at functional knowledge levels, stable unit cost, flexible manufacturing, easy access to in...
