This paper presents an end-to-end deep convolutional recurrent neural network solution for Khmer Optical Character Recognition (OCR) task. The proposed solution uses a sequenceto-sequence (Seq2Seq) architecture with an attention mechanism. The encoder extracts visual features from an input text-line image via layers of convolutional blocks and a layer of Gated Recurrent Units (GRU).

Ebook "The entolomataceae of Tasmania" is the result of 14 years of collecting Entolomataceae in the native forests of Tasmania, Australia. Although initially involving only the Tasmanian residents Genevieve Gates and David Ratkowsky, who made twice- or thrice-weekly forays into the forests throughout the year, the project was subsequently joined by agaric specialist Machiel Noordeloos from the Netherlands, and by fungi photographer Michael Pilkington from the United Kingdom.

Automatic extraction of chemical-disease relations (CDR) from unstructured text is of essential importance for disease treatment and drug development. Meanwhile, biomedical experts have built many highlystructured knowledge bases (KBs), which contain prior knowledge about chemicals and diseases. Prior knowledge provides strong support for CDR extraction. How to make full use of it is worth studying.

Electron transport chain is a series of protein complexes embedded in the process of cellular respiration, which is an important process to transfer electrons and other macromolecules throughout the cell. It is also the major process to extract energy via redox reactions in the case of oxidation of sugars.

The mechanical bypass uses a slotted rod that is actuated by a lever on the large dashpot plunger shaft to provide another leakage path in the dashpot. The lever is positioned so that the bypass opens at a gate position above speed no load, when the unit is normally on line. If it is necessary to operate isolated, the bypass arm is moved out of the way and the unit dashpot will function normally. The solenoid operated dashpot bypass provides a leakage path in the dashpot when the solenoid is energized. The rate of leakage is...

The first adjustment to the governor is the full rate gate timing. The stop nuts on the governor main valve are adjusted to limit the amount of travel of the main valve. By changing the maximum movement of the main valve, the amount of oil flowing to the servomotors is changed, and, therefore, the maximum speed at which the wicket gates travel is changed. The rate at which the wicket gates close determines the magnitude of penstock pressure transients or water hammer and the maximum speed of the unit following a load rejection. Faster wicket gate...

The transfer valve is a three-way hydraulic valve that (1) permits the selection of the main distributing valve or the auxiliary valve for operating the wicket gates or (2) closes both valves. The main valve and the auxiliary valve each have plungers that can close off the pressure, opening, and closing ports of the valves. The bottom of the plungers have a smaller diameter than the top so that if oil is routed to the top of the plungers they will be forced closed. The transfer valve routes oil to the top of the plungers of the valve...

Many units also have a second solenoid operated shutdown device that is usually identical to the emergency shutdown solenoid. It may be used as a normal shutdown solenoid or a speed no load solenoid. If it is used as a normal shutdown device, its operation will still close the wicket gates, but unlike the emergency shutdown solenoid, it does not need to be reset manually. A speed no load solenoid typically moves the gate limit to some value just above the speed no load gate position. The speed no load solenoid is usually tripped during startup and...

Most cabinet actuator type governors also have a smaller auxiliary valve to control the gate position. Because of the relatively small ports of the auxiliary valve, the gates are moved slowly and can be positioned precisely. The auxiliary valve has no connection to the ball head, and therefore, no speed control. There is also no protection from the shutdown solenoids when on auxiliary control. A unit should never be left unattended when operating with the auxiliary valve. When operating with the auxiliary valve, the gates are moved by moving the gate limit.

The speed adjustment allows adjustment of the speed of the unit when it is off line, and it also allows adjustment of the loading when the unit is on line. The mechanism by which it accomplishes its purpose depends on the design of the governor, but in all cases, adjusting the speed changer moves the pilot valve off center, which causes the gates to move (figure 6). If the unit is off line the gates will continue to move until the change in unit speed causes the flyballs to move enough to recenter the pilot valve. When...

The hydraulic system consists of an oil sump, one or two oil pumps, an air over oil accumulator tank, and piping to the servomotors. Typically, there are two pumps with lead and lag controls so that there is always a backup pump. Some systems will share two pumps between two units so that in an emergency one pump could be used for both units. The accumulator tank is usually sized so that in the event the pumps fail, the gates can still be closed. The size of the valve required to control the large amount of oil...

An upright „Stop‟ sign is present on both approaches to the Level Crossing, on the public road within the railway boundary which indicates to the road users that they must come to a full stop. In the case of this Level Crossing, the „Stop‟ sign is in line with the Level Crossing gates, see Photograph 3. In the case of this Level Crossing, once the road user opens the Level Crossing gates the road user must continue towards the decision point. The decision point is the position where the road user can stop their vehicle clear of...

The metal gates positioned on each side of the Level Crossing are approximately 4.3 m wide and open away from the railway. The surface of the intersection of the road with the track is covered in rubber „Strail‟ units, which gives a level surface over the track. Cattle grids are installed on each side of the roadway, where it crosses the track to prevent cattle straying onto the railway line. There is concrete post and wire fencing running between the gates and the boundary hedges, see Photograph 2. There is a residential house...
