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.

A robotic sensor network is advantageous in performing a coverage task compared to the static sensor network due to its ability to self-deploy and self-reconfigure. However, due to the limited sensing range, when mobile sensors are initially deployed, sensors located far away from the area of interest may not be able to participate in the coverage task. Furthermore, since in reality the mobile sensors have only a limited energy storage, the movement of the sensors have to be as efficient as possible. In this paper, we consider a robotic sensor network with a limited anisotropic sensing range and energy storage. The sensing performance is assumed to be dependent on both the position and orientation of the target to the sensor and its range is reduced along with the movement of the mobile sensor. This paper proposes a new algorithm that guarantees the participation of all sensors in the network while at the same time maintains the energy utilization as optimum as possible. We combine the standard coverage algorithm with the leader-following algorithm where the standard coverage algorithm is further modified in order to take into account the energy consumption of the sensors. Simulations show the effectiveness of the proposed algorithm.

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。

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.

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).

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 presented a research on the Mobile wireless communications which are most advanced form of human communications. The research focuses on Soft Handover (SHO) where the User Equipment (UE) is connected simultaneously to several Node B(s) on the same frequency. The objective of this paper is to evaluate the differences of Soft Handover parameters of addition and drop windows impacts on network performance. The network performances will be focus on the SHO transport network overhead. The drive test was conducted to collect real measurement data in live UMTS network. The data are analyzed and simulated to examine the behavior of Soft Handover events. It is shown that the addition and drop windows have decisive effects on the SHO transport network. Thus, the parameter for addition and drop windows setting should be planned properly to mitigate the SHO transport network overhead and effect. This research would benefit the network administrator to manage and realize users on the performances in the mobile wireless communication.

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.
