In this paper, we present a Radial Basis Function Neural Network (RBFNN)-based Nonlinear Auto-Regressive Model with Exegeneous Inputs (NARX) model of a DC motor drive controller model by (Rahim, 2004). Tests were conducted to measure the accuracy of the model (using One Step Ahead (OSA) and its validity (using correlation tests and histogram analysis). The resulting model produced Mean Square Error (MSE) of 8.53 × 10−3 and 8.82 × 10−3 on the training set and test set, respectively, while fulfilling all validation tests performed.

Performance analysis of a power line communication system over a non-white additive Gaussian noise channel 非白加性高斯噪声信道上电力线通信系统的性能分析

Performance analysis of a power line communication system is presented considering the noise as a cyclostationary non-white Gaussian random process. The instantaneous variance of noise is considered as a function of frequency with an exponential power delay profile. An analytic approach is presented to evaluate the performance of a power line communication link in the presence of the above limitations. The expression of the signal to noise ratio is developed considering the frequency and time dependence of the cyclostationary noise. The system bit error rate (BER) is then evaluated numerically for several system parameters like system bit rate, Fourier coefficients of the non-white Gaussian noise process etc. The BER results show that there is deterioration in system BER due to time and frequency dependence of noise and the degradation is found to be significant at higher bit rates and bandwidth. The system suffers penalty in receiver sensitivity due to non-white nature of the noise process.
对电力线通信系统进行了性能分析,考虑噪声是一个循环平稳的非白高斯随机过程。噪声的瞬时方差被认为是频率的函数,具有指数型的功率延迟曲线。提出了一种分析方法来评估存在上述限制的电力线通信链路的性能。考虑了周期平稳噪声的频率依赖性和时间依赖性,给出了信噪比的表达式。然后对系统的比特率、非高斯白噪声过程的傅立叶系数等系统参数进行了系统误码率的数值计算。结果表明,由于噪声的时间和频率依赖性,系统的误码率会下降,并且在更高的比特率和带宽下,系统的误码率下降更为明显。由于噪声过程的非白性质,系统在接收机灵敏度上受到了惩罚。

In mobile robotics, sometimes a non-conventional locomotion is more suitable where the terrain is rough, uneven, unstable surface or the path has only small opening for maneuvering such as in a search and rescue situation, exploration of hostile area or handling of hazardous materials. Dragging is a type of non-conventional locomotion has the benefits of being physically small, able to move on rough surface and simple to implement. This paper describes a tele-operated three-finger robot that uses dragging to achieve locomotion. Through coordinated motion of the three fingers, it can move forward, backward, left and right by dragging its body.
在移动机器人中,有时在地形粗糙、凹凸不平、表面不稳定或路径只有很小开口的情况下,如在搜索和救援情况下,探索敌对区域或处理危险物质时,非常规运动更适合。拖拽是一种非传统的运动方式,它的优点是体积小,能够在粗糙的表面上移动,而且操作简单。本文介绍了一种采用拖动方式实现移动的遥控三指机器人。通过三个手指的协调运动,它可以通过拖动身体向前、向后、向左、向右移动。

This paper presents the methodology of converting an asynchronous design to a synchronous design. As the size of transistor is shrinking, the difficulty of a design to meet the timing has increased. Continuously shrinking of transistor size from time to time has increased the on-die variation such as Process, Voltage, and Temperature (PVT) variation of the chip. Since Performance Verification (PV) or Static Timing Analysis (STA) tools is unable to accurately calculate the timing of asynchronous design, asynchronous design is required to migrate to synchronous based design for the STA tools to ensure the silicon timing can be met across PVT. A proper design methodology of converting asynchronous design to synchronous design is proposed in this paper. An Intel 8254 Programmable Interval Timer (PIT) is used as a case study. Current Intel 8254 timer is an asynchronous based design and it has approximately 12,000 gates. STA is performed after conversion and results shows the timing of synchronous design can be fully verified by STA. Additional comparison for area is made as well.
本文介绍了将异步设计转换为同步设计的方法。随着晶体管尺寸的不断缩小,满足时间要求的设计难度也随之增加。晶体管尺寸的不断缩小增加了芯片上的变化,如工艺、电压和温度(PVT)变化。由于性能验证(PV)或静态时序分析(STA)工具无法准确计算异步设计的时序,因此异步设计需要迁移到基于同步的STA工具设计中,以确保跨pvt可以满足硅时序。本文提出了将异步设计转换为同步设计的适当设计方法。使用Intel 8254可编程间隔定时器(PIT)作为案例研究。目前的英特尔8254定时器是基于异步的设计,它有大约12000个门。转换后进行了恒态分析,结果表明,恒态分析可以充分验证同步设计的时序。另外还对面积进行了比较。

This paper evaluates energy level performance of error control strategies in Wireless Sensor Networks (WSNs) in presence of Rayleigh fading. More precisely Forward Error Correcting (FEC) and Automatic Repeat Request (ARQ) technique are studied for a square grid WSN. ARQ scheme is compared with FEC scheme in terms of Packet Error Rate (PER), energy efficiency and total energy spent to communicate packetized data. The impact of Rayleigh fading, node spatial density and packet lengths on energy efficiency and energy expenditure is discussed. Further an optimum FEC scheme with the maximum energy efficiency for a given node spatial density and packet size is investigated. The impact of node spatial density, Rayleigh fading and packet length on optimal error correcting capability is indicated. Energy efficiency for several error correcting capabilities and packet lengths is also evaluated.

A single-mode ring resonator which is fed along one of its quarter-wavelength sides is presented. The resonator's response presents transmission zeros whose frequencies can be modified by adjusting the line impedance of the ring and the coupling level of the feeding coupled-line. The proposed topology introduced much simpler bandpass filter configuration and reduced the number of control parameters. This idea is tested on FR4 microstrip substrate using the electromagnetic simulation. The measurement results are then presented in this paper to show its feasibility.

This paper presents new numerical injection model of Inter Line Power Flow Controller (IPFC). Indeed, linear model of voltage source inverter of IPFC is improved to estimate steady-state operation of IPFC as well as Static Synchronous Series compensator (SSSC) in power system. The proposed method estimates the effect of IPFC on active and reactive line power flow with SSSC for three modes such as resistive, capacitive and inductive. Thus, it is recommended that the proposed technique can be applied for prediction of initial injected voltage and its phase angle of IPFC and SSSC for their modeling in real system. The tested system for simulation is based on IEEE two machine systems. The result of simulation and the numerical analysis shows the robust accuracy of obtained estimation of IPFC and SSSC.

In this paper, the design of software module using ‘schematic’ for Xilinx FPGA (XCV50-4-CS144) based protection unit for synchronous generator is presented. The tools used for building and testing the software modules are Xilinx Foundation Series 3.1. Before verifying the design on FPGA the complete design is simulated using Modelsim Simulation tool. A test simulation is written where, the set points speed can be changed for the motor. It is observed that the motor speed gradually changes to the set speed and locks to the set speed. The synchronous generator protection unit can carry out all necessary generator protective functions. The synchronous generator protection unit is easily re configurability features rather than high accuracy and processing speed for generator signals. In this paper I present compact system in one unit and multiple generator protections.

Multi-user navigation: A 3D mobile device interactive support 多用户导航:支持3D移动设备交互

Multi-User navigation within an environment with the aid of 3D mobile support provides end users with additional mobility thought and improves mobility services' efficiency. A necessary approach of using mobile device for navigation aid is to display only a section of the view-front and to let users control the portion shown by conceptually moving on the orientation. There is a need for multiple users to be able to interact with themselves when they are within an environment and navigating with the aid of 3D mobile devices support, in order to meet-up with an appointment or to be aware of the locations of each other. Unfortunately, the predominant 3D mobile navigation system does not provide multi-user interactive services. Users cannot be aware of other users navigating within same environment using the same system on their mobile devices at the same time. This paper presents multi-user 3D mobile navigation system for providing multiple user awareness. The analysis of the results provides a unique visualization of multiple users using mobile devices to help them navigate to a target location by being aware of their whereabouts.
在3D移动支持的帮助下,环境中的多用户导航为最终用户提供了额外的移动思维,提高了移动服务的效率。使用移动设备辅助导航的一个必要方法是只显示视图前面的一部分,并让用户通过概念上的方向移动来控制显示的部分。我们需要多个用户能够在一个环境中与自己互动,并在3D移动设备支持的帮助下导航,以便与约会见面或了解彼此的位置。不幸的是,主流的3D移动导航系统不提供多用户交互服务。用户无法意识到其他用户同时在同一环境中使用同一移动设备上的同一系统进行导航。针对多用户感知问题,提出了一种多用户三维移动导航系统。对结果的分析提供了使用移动设备的多个用户的独特可视化,通过了解他们的位置来帮助他们导航到目标位置。

This paper presents theoretical investigations into the dynamic characterisation of a two dimensional gantry crane system. A dynamic model of the system is developed using Euler-Langrange formulation. Simulation exercises are performed in Matlab with three different control strategies; LQR, DFS and PD controllers and then the results are compared with uncontrolled system. To study the effects of payload weight on the response of the gantry crane system, the results are evaluated with different payload weight in the algorithm. Results achieved from simulation work are shown in time and frequency domains. Performance of the feedback controllers in minimizing the sway angle is examined in terms of time response specifications and magnitude of sway. Finally, a comparative assessment of different payload weight to the system performance is assessed and discussed.
