Despite advances in automatic medical image segmentation, time-effective interactive correction tools are commonly required in the clinical environment. In this work we present a new interactive correction method for abdominal multi-organ segmentation. Our method enables 3D shape corrections through 2D interactions. During runtime local corrections are used to build a conditional model, which i...

A new on-line titrator for pH control has been developed. The on-line identification method generates an estimate of the inverse titration curve as a continuous smooth function eliminating the need for selection of the important break points of the titration curve. The time required to obtain the titration curve in the spanned pH range is approximately twice the settling time of the titrator an...

PI controller has attracted researchers in industrial control processes because of its simplicity and robust performance in a wide range of operating conditions. It has been used to provide proportional delay differentiation on web servers in pervious work. However, PI controller can not achieve satisfactory results due to (1) the web server’s non-linearity properties (2) the difficulty of buil...

New charge-recycling structure and driving scheme for TFT-LCD source-driver IC application are proposed. The number of additional switches for the charge recycling is greatly reduced. An experimental prototype 6-bit source driver with five-level sevenphase charge recycling implemented in a 0.35-μm CMOS technology demonstrates that the quiescent current is only 3.1 mA, dynamic power saving is 75...

The performance of an antenna control system is evaluated using performance parameters such as settling time, bandwidth, steady-state error in rate offsets, and antenna root-mean-square servo error while tracking in wind gusts. The performance parameters are measured in the field or obtained through analysis and simulations. Limited access time to antennas, incomplete test equipment, limited te...

In this paper, Load Frequency Control (LFC) of isolated single area and two-area re-heat inter-connected thermal power system has been carried out by the classical controllers i.e. I, PI and PID; and implemented on the system at 1% step load perturbation under nominal loading conditions. The system responses have been simulated in MATLAB R2010a. Responses of deviation in frequencies, deviation ...

Power System Stabilizers (PSSs) are used to enhance damping of power system oscillations. This paper presents a new fast algorithm to develop PSS. According to this regard, Water Cycle Algorithm (WCA) is used to detect optimum Power System Stabilizer parameters. For this purpose, the design problem of PSS is formulated as an optimization problem and WCA by forming three subsidiary objective fun...

The analysis study has been done for a First Order Plus Delay Time (FOPDT) model controlled by Proportional Integral Derivative (PID), proportional integral(PI),Internal Model Controller(IMC) and Model Predictive Control (MPC) using MATLAB software. The study has been done for both MPC and conventional control methods to design the controller for the level tank system and the results has been c...

Fractional order calculus is currently experiencing a wide application in controlling different types of processes. The focus has been directed towards the design of robust controllers for single-inputsingle-output systems, with very few tuning examples for the multivariable ones. The purpose of the present paper is to describe a simple and effective method for designing a multivariable fractio...

This technical note addresses the distributed fixed-time consensus protocol design problem for multi-agent systems with general linear dynamics over directed communication graphs. By using motion planning approaches, a class of distributed fixed-time consensus algorithms are developed, which rely only on the sampling information at some sampling instants. For linear multi-agent systems, the pro...
