This paper presents the comparison of performances between a PID temperature controller and a conventional on-off temperature controller for home-applied refrigerator. A new PID temperature controller was designed to replace the conventional on-off temperature controller to maintain the inner temperature of a refrigerator. Both temperature controllers of the conventional system and the PID were designed...
A new full-wave rectifier circuit employing only two differential difference current conveyors (DDCCs) is presented. The proposed circuit exhibits high input impedance, good temperature stability and wide bandwidth. It is extremely simple and compact, and suitable for IC implementation. The circuit also offers a low output impedance terminal, which is suitable for low impedance load. The simulation...
Dynamic equations of the biped robots are easily obtained by the Lagrangian method. Because of terrible nonlinearity of these dynamic equations, the actuator's dynamic is employed to linearize these equations. By this way, the heavy nonlinear equations are replaced with a second order linear system which their coefficients are achievable by the various identification methods. Here least square method...
The primary goal of this research and development project is to develop a pick and place robot for material handling systems. Possessing two degrees of freedom, this semi-automatic pick and place robot integrates object detection with the pick and place process whereby the detection of an object would power the object gripper; kick starting the pick and place process. With the objective of creating...
Mobile robot has been a major role to the application in military, industrial and agricultural purposes. Mobile robot should navigate through desire route and avoid the obstacle within the path. Many researcher come with the solution by using the various type of control and instrumentation system. The complexity of mobile robot system can make the system cost intensive and high risk. Proposed is a...
Point-to-point (PTP) motion control systems play an important role in industrial engineering applications such as advanced manufacturing systems, semiconductor manufacturing systems and robot systems. Until know, PID (proportional-integral-derivative) controllers are still the most popular controller used in industrial control systems including PTP motion control systems due to their simplicity and...
Security of an information system depends to a large extent on its ability to authenticate legitimate users as well as to withstand attacks of various kinds. Confidence in its ability to provide adequate authentication is, however, waning. This is largely due to the wrongful use of passwords by many users. In this paper, the design and development of keystroke pressure-based typing biometrics for...
A non-parametric-based technique using epsiv-insensitivity support vector regression (epsiv-SVR) is proposed and developed in this work for the identification of friction in a DC motor-driven motion control system. The effectiveness of the developed SVR-based friction model to compensate the frictional effects is evaluated experimentally on a rotary experimental set-up for both point-to-point (PTP)...
The aim of this study is to investigate artificial neural network (ANN) for prediction of drug contents. Hydroxypropylmethylcellulose and loratadine specifically were selected as model matrix polymer and drug. All 0, 5, 10, 20 and 40 mg drug loaded in hydroxypropylmethylcellulose films were conditioned at the relative humidity of 25, 50 and 75% each prior to psysicochemical characterization using...
This project presents the performance analysis of Wireless Sensor Network (WSN) used in the high-end applications such as weapons sensor ship, biomedical applications, habitat sensing and seismic monitoring. Recently WSN also focuses on national security applications and consumer applications. This project shall demonstrate the performance of WSN models, which are created and simulated using QualNet...
In this paper, a novel method to detect partially occluded humans in still images is proposed. An individual human is modeled as an assembly of natural body parts. Some part based SVM classifiers are trained first by using histogram of orientated gradient feature. Different from other boosting methods, region information is stored in each classifier. When detect human in crowed scene, according to...
The main objective of this study is to determine the optimum tuning of temperature process control for overdamped process response. The Ziegler Nichols tuning was used to determine the optimum setting of temperature process control in 30degC - 50degC by varying the PB and I term. The performance of the response is evaluated based on integral absolute error (IAE), settling time (Ts), and rise time...
Attitude control system is designed to change the attitude of a satellite, able to meet pointing requirement, eliminating external disturbances, a low-cost controller as well as a high reliability control system which can be applied and embedded to a real time application. An adaptive predictive Mamdani fuzzy logic controller (FLC) is introduced in this paper. A predictive control is needed to estimate...
A voltage-mode versatile multifunction filter with four inputs and three outputs biquadratic filter based on simple CMOS operational transconductance amplifiers (OTAs) is presented. By appropriately connecting the input and output terminals, the proposed circuit can work as either a single-input multiple-output (SIMO) or a multiple-input single-output (MISO) filter without changing the circuit topology...
This research focuses on the correlation between body mass index (BMI) and brainwave activity measured using EEG, concentrating on Alpha and Beta waves. BMI is a measurement of body fat based on height and weight. Using BMI as reference, all 63 samples were given interviewed and then categorized into 3 groups before undergoing EEG recording. The groups are underweight (index < 20), ideal weight...
