ABSTRACT:
Conventional closed die forging, is widely used for manufacture of superalloy parts. Despite recent technological advancements in the area of forging design, empirical and trial-and-error methods are still widely used in forging super alloy materials. This paper investigates the effect of flash thickness and various geometrical forging design parameters including internal and external drafts and internal and external corner radii, on the die cavity filling, forging load and raw material cost when forging Nimonic80-A a supera ....etc

Wireless based Automatic dam water level control shutter open /closed with emergency information System
ABSTRACT
In this project to maintain the dam water level. it’s very use full for emergency time every information is going though control area so easily identify the dam information if the dam water level will be high the shutter automatically open depending upon the water level. The information is going though the particular person here we have used RF wireless communication

Open loop control vs. closed loop (feedback) control



The next two figures present the structures of open loop and feedback control systems.
Figure 1 shows an open loop control system whose function is to cause the output y(t) to follow the
reference r(t).
Feedback control system design for zero steady state error
In general, to follow a reference R(s) with zero steady-state error, the path between the
reference and the system output should contain a term like R(s). For instance, to follow a ramp
(velocity ....etc

An industrial plant has hundreds or even thousands of control loops. The performance of control loops is important to ensure high product quality and low cost of the product in such plants. In general, oscillatory variables are one of the main causes for poor performance of control loops. Therefore, detection and diagnosis of the causes of oscillations in control loops is very vital for maintaining the product within the desired quality limits. Identification of such source signatures is a very important task in assessing closed loop control pe ....etc

Abstract -
In recent years, mining of sequential patterns has been studied extensively in various domains. Most of the existing algorithms find patterns in transactional databases. This paper proposes a novel algorithm to mine closed sequential patterns using an inverted matrix and prefix based sequence element matrix. Inverted matrix minimizes the search space for discovering various sequential patterns of different items. We use a prefix based sequence element matrix to minimize the scans required at levels k and ....etc

Closed loop timing



Bundled closed loop timing

Signal AD and ref signal Aclk transition tncq after each transition on Tclk
Vector BD and reference Bclk transition tnAB later.
Timing loop locks the quadrature clock Qclk to Bclk with offset lag equal to aperture offset ta0 of phase detector of flip-flop
This places the receive clock, Rclk which is offset from Qclk by П/2
Aperture is exactly centred on the eye of data vector BD.

Which of these elements of timing uncertaintyare cancelled?

Abstract

In this study, we propose some simple but effective throughput-approximation methods for finite-buffered closed-loop production systems with unreliable machines and exponentially distributed processing times. The proposed approximation methods are based on decomposition and aggregation principles. According to the method representing the decomposed systems, three different approximation methods are developed, along with a simple upper bounding method for throughputs. Extensive computational experiments are perform ....etc

Abstract
In this paper, a systematic overview of PLL-based closed-loop control methods for interleaved DCM/CCM boundary boost PFC converters is presented. It is shown that the PLL-based closed-loop methods always provide stable operation, unlike the open-loop control methods, where the only method which results in stable operation is the slave synchronization to the turn-on instant of the master with current-mode control. It is also shown that the dynamic response of the PLL-based closed-loop methods with master-slave approach and dem ....etc
