Productivity Control loops are a vital part of the process industry and are especially important when it comes to quality, economy and safety. In fact, a significant portion of incorrectly tuned automatic control loops can actually decrease production performance rather than improve it. The availability and effectiveness of a control system is essential for operating the process safely and at m...

The compensating devices are controlled in the structure of automatic control system conjunction with sensors included a particular node power grid. But overall state local grid for reactive flow is not considered. It proposed to generate signals correction by processing information obtained monitoring from remote voltage and current distribution possible use matrix method forming adjust parame...

Water control technology aims to provide a sufficient water supply avoid overflow. An automatic valve sluice gate made from fiberglass is preferred for in tidal agriculture. The mechanical model can automatically release and close discharge at precise angle optimize advantage of this design its utilization the difference between upstream downstream levels on gate. A with slope 15° recommended l...

This research aims to make a miniature ore material transfer tool automatically using Omron PLC. The way this works is that when the start button pressed, motor 1 will move apron containing be taken 3 storage barrels filled alternately. In each barrel, proximity sensor installed detect level of filling. On rails are passed by apron, there three limit switches serve as indicators position right ...

Cross–derivatives are mixed partial derivatives that are obtained by differentiating at most once in every coordinate direction. They are a computational tool in combinatorics and high– dimensional integration. Here we present two methods of computing exact values of all cross– derivatives at a given point both following the general philosophy of automatic differentiation. Implementation detail...

ii) The control valve Manufacturer can only state the Inherent valve characteristics, which refer to the flowrate (F) – valve travel position (m or Z) relationship, when the pressure drop across the control valve (DPV) is constant. Note that the pressure drop across the control valve (DPV) can be almost constant only if the piping system pressure drop (DPS) is concentrated at the control valve ...

The need for cleanliness and availability of water the community is also getting higher. Currently, people use conventional faucets which can cause waste because are not tightly closed or must be directly. Technological advancements to innovated help in movement save clean water, one Arduino microcontroller. Based on these problems, author made a prototype making automatic equipped with motion ...
