Piezoelectric drive mechanisms consist of piezoelectric materials that actuate the mechanism at different ranges of frequency, as the piezoelectric actuators are subjected to a nonlinear phenomenon of hysteresis which is sensitive to frequency changes. Designing an adaptive hysteretic model facilitates the operation of such mechanisms in general control framework. In this paper, an Integrated Rate and Inertial dependent Prandtl-Ishlinskii model using an exponential function for varying damping factor is proposed for positioning control of a piezoelectric actuator at frequency range between 1 Hz to 200 Hz.

The development of MEMS accelerometer application as seismic sensor is discussed in this paper. The system consists of a sensor signal conditioning, microcontroller circuits, and application programs for data acquisition system. Two capacitive type sensors are used in the system. With the most recent technology of MEMS, it is possible to construct an integrated seismometer using only one chip of MEMS sensor, which traditionally three separated sensors must be employed. From the experiment using calibrating signal, it is shown that the the sensitivity of the system could be increased by the factor of two.

Data transmission between RTUs (Remote Terminal Unit) and HMI at control center in SCADA (Supervisory Control And Data Acquisition) automation system is accompanying with delays due to several reasons such as: limitation in data transmission rate, distance between RTU and control center, traffic of communication network and the time needed for data modulation and processing. These delays can cause errors in delivered measurements to the HMI at control center. This paper evaluates how these communication delays can affect the accuracy of transmitted measurements as viewed by HMI in automation system of a real power distribution network. Experimental measuring has been performed to obtain the time delays in data exchange between RTU and HMI. A stochastic model, based on the obtained experimental results, is then employed to model the data transmission delay for that real automation system of power network. It will be shown how the accuracy of delivered measurements to HMI will change depending on the change rate in power network conditions when there are delays in data transmission network of the SCADA automation system.
在SCADA (Supervisory control and Data Acquisition)自动化系统中，由于数据传输速率的限制、RTU与控制中心之间的距离、通信网络的流量以及数据调制和处理所需的时间等原因，RTU与控制中心HMI之间的数据传输存在一定的延迟。这些延迟可能导致在向控制中心的HMI交付测量结果时出现错误。本文评估了在实际配电网自动化系统中，这些通信延迟对HMI传输测量精度的影响。实验测量了RTU和HMI之间数据交换的时延。在实验结果的基础上，采用随机模型对实际电网自动化系统的数据传输时延进行建模。当SCADA自动化系统的数据传输网络存在延迟时，交付给HMI的测量结果的准确性将如何根据电网条件的变化率而变化。

The underwater acoustic method is a powerful tool for assessment of fish abundance. The acoustic transmitting and receiving system was developed to measure fish target strength and fish density. From this study, we found the target strength of fish has a high correlation with fish length. By calculating the fish target strength with acoustic parameter we found the value of fish density.

Fuzzy logic has mostly been used in different kind of field either in taking decision, or control system and forecasting. Fuzzy logic is one that can represent a complex situation into a simple form in a language that is easily caught by humans. Similarly, to represent the nature of weather easily understood by ordinary people, this is the result of weather forecasting based on meteorological data. Some of the statistical methods used for weather forecasting are Auto Regressive (AR), Integrated Moving Average (ARIMA) and found some shortcomings of these traditional method. That is the need for historical data is not small, low-prediction accuracy results in a complex condition. This paper describes the strategy in weather forecasting based on fuzzy logic for maritime weather. Case studies conducted in the Java Sea, cruise lines Surabaya- Banjarmasin. The results showed that the level of accuracy prediction for 86.64% of the Java Sea, and prediction accuracy decreased for the next 24 hours ahead. Predictors of ability to demonstrate the ability to detect anomalous high sea waves in the waters of the Java Sea

The objective of this project is to develop a Quadrupedal (four legs) robot with speech recognition to control the movement. There are only three words of command to be recognized, which are “forward”, “backward”, and “left” command. Fourbar linkage is used as the basic mechanism for the robot's legs and comparison of sum of absolute error is used on the speech signal spectrum taken from its short time fourier transform.

This paper focuses on the optimization of the truncated power series for the inverse kinematics solution that was obtained in the earlier work for a six-legged robot. The inverse solutions were used to approximate the displacement angle for input values for the three servos S1, S2, and S3 using the three desired parameters R, Z, and angle ?. The truncated solution was complex and mathematically tedious, requiring 16 coefficients to be used to compute S1 and 165 coefficients to compute S2 and 145 for S3. In this research, a neural network was used to replace the highly complex power expansions. Single neural networks were used to compute S1, S2, and S3 separately. The networks were optimized such that each network had eight hidden layers. The neural networks provided good accuracy in the solutions they obtained. Most importantly, the approach reduced the high demand for mathematical resources significantly below the resources required by the power series method. The goal of this research is to use the results reported in this paper in the implementation of a field-programmable gate array (FPGA).

This paper describes a new technique of fabricating low-cost and flexible microfluidic device for point of care diagnostics in remote region or developing countries. The technique is inspired from a traditional and ancient textile dye-resist technique, namely batik. In batik technique, wax is used to protect regions of textile material from the colouring dye(s). Similarly, we modify the wax content in cloth for defining hydrophilic channel for controlling fludic flow at micro liter volume level. Separate fluids can be dropped at different sites, and flown into a reaction site for inducing diffusion-induced mixing. As a comparison, we also fabricated cloth microfluidic device using a technique similar to that proposed by previous researchers to build 3-dimensional (3D) paper-based microfluidic device. The device made using our proposed technique can give clearer colour change display due to the mixing of different dyes. Such device could serve as a low-cost analytical device based on colorimetric (colour change) assay.

This article discusses the issue of Ozone depletion in global warming, factors causing Ozone depletion and the design of monitoring system. In developing countries like Malaysia, the rapid growth of industrial sectors does not only bring income to the nation, but also causes pollution in various forms. It is well known that air pollution has significant contribution towards global warming through Ozone depletion, whereby the emission of toxic gas from industries such as CFC would slowly thin the Ozone layer. Therefore, apart from taking efforts to prevent or reduce air pollution, the monitoring of factors known to deplete ozone should also be undertaken. In view of this, an instrument that could monitor the quality of Ozone on daily basis was designed. The instrument comprises of two main blocks; the data logger and Graphic User Interface (GUI). The data logger uses 16-Bit Microcontroller as the main control board housing data logger algorithm, Solar Tracker algorithm and data storage block. Three sensors were used in the data logger to measure the temperature, humidity and ultraviolet rays. The system had been tested at the field to capture data in two different conditions; at the industrial and high attitude areas. The measurement was carried out for 2100 hours to monitor the reliability, durability and accuracy of the instrument
