This paper presents simulation of ANN control approach of electric machine (EM) used in Plug-in Hybrid Electric Vehicle (PHEV). The EM is constructed in MATLAB/Simulink and the feedback closed-loop control system of ANN controller has been developed. A power reference curve has been used as reference for the EM that represents the load demand of the PHEV. The control system has been simulated to obtain optimal control parameters of the system that can optimally track the power reference curve. The proposed ANN controller developed has been compared with two previously studied methods of using conventional PI based speed controller and the PI-PSO based controller. From the simulation results, it has been shown that the proposed method is much better than the conventional PI based method and also relatively comparable to the results of PI-PSO method. This shows that it is alternative way of using the intelligent controller of ANN to replace the conventional method of PI control system.

This paper presents the new coil design strategy for Wireless Power Transfer (WPT) applications. In order to produce better power transfer efficiency for remotely located load, hybrid approach is proposed using two different coils such as conical and spiral. Hybrid approach refers the coil model by engaging conical as a transmitter and spiral as a receiver in a single system. The field pattern of conical coil is cumulative so that better magnetic field is possible at the bottom side for high directivity. In contrast, the spiral coil produces distributive field pattern so that the field distribution is uniform. Taking advantage of these two different behaviors, better power efficiency would be achieved by reducing power loss in the coil zone. For this hybrid approach, Finite Element Method (FEM) based conical and spiral coils were developed and simulated to determine field patterns and their value. Two different prototypes (Conical and spiral) were experimented with fixed spiral load coil to validate the performance of the hybrid approach. The output load coil voltage and efficiency plots were made based on the measurement, for analyzing the system performance. It is recorded the efficiency of 72% with the optimum distance 10cm and biasing voltage 10V respectively. The results from simulation as well as experiment confirms that hybrid approach could support significantly to reduce power loss and increase the relative operative distance.
本文提出了一种新的用于无线电力传输(WPT)应用的线圈设计策略。为了提高远程负载的电力传输效率,提出了采用锥形和螺旋两种不同线圈的混合方法。混合方法是指在单一系统中采用锥形作为发射器和螺旋作为接收器的线圈模型。锥形线圈的磁场模式是累积的,因此可以在底部获得更好的磁场,从而获得高指向性。相比之下,螺旋线圈产生分布场,使场分布均匀。利用这两种不同的行为,通过减少线圈区域的功率损耗,可以实现更好的功率效率。针对这种混合方法,开发了基于有限元法的锥形线圈和螺旋线圈,并对其进行了仿真,以确定场型及其值。在固定螺旋载荷线圈下,对两种不同的原型(锥形和螺旋)进行了实验,验证了混合方法的性能。根据测量结果绘制了输出负载线圈的电压和效率图,分析了系统的性能。在最佳距离为10cm,偏置电压为10V时,效率为72%。仿真和实验结果表明,混合方法可以显著降低功率损耗,增加相对操作距离。

This work proposed a low noise figure 2.4 GHz down-conversion CMOS mixer for wireless sensor network (WSN) application using 0.13-μm Silterra technology. The proposed down-conversion mixer converts a high radio frequency (RF) signal from 2.4 GHz to an intermediate frequency (IF) of 100 MHz through the use of a local oscillator signal (LO) of 2.3 GHz. The proposed mixer employs a double balance Gilbert-cell topology with integrated input matching at the input stage and a low pass filter at the IF stage. The simulation results indicate that the proposed mixer obtains lower noise figure (NF) of 5.21 dB with an input third-order intercept point (IIP3) of 0 dB. Furthermore, the conversion gain (CG) of 8.6 dB is achieved with the power consumption of 1.57 mW at 1.8 V supply voltage.

This paper presents the design of a 60 GHz microstrip filter to be incorporated in an LNA circuit in CMOS at millimeter-wave (mmW) frequencies. The proposed filter is designed using 8-metal layers of 0.13μm Silterra RF CMOS technology with ultra top metal (UTM) as the signal line and metal M1 as the ground plane. The structure was simulated using 3D EM simulation tools, resulting in the insertion loss of 0.00874 dB and input and output return losses of 44.7 and 42.8 dB, respectively at 60 GHz resonant frequency. The filter design is potentially useful as the input and output matching of 50 Ω for millimeter-wave (mmW) LNA.

Titanium dioxide (TiO2) nanorod arrays (TNAs) were deposited on fluorine-doped tin oxide (FTO) coated glass substrate via a novel and facile method at the lowest deposition temperature of 110 °C for 3 hours, and characterized via fiel-demission scanning electron microscopy (FESEM), and ultraviolet-visible (UV-Vis) spectrophotometer. Self-powered UV photosensor was assembled according to photo-electrochemical cells (PEC) structure using the deposited TNAs as photoanodes. The fabricated UV photosensor was then studied for its electrical property. The fabricated UV photosensor exhibits fast response with high sensitivity under UV irradiation. A distinct ON/OFF ratio of the fabricated PEC structure also exhibits photo-sensing property as photo-anode, and can be implemented for the application of UV photosensor. The large contact area of the TNAs/electrolyte interface leads to the generation of photocurrent and exhibits improvement in conductivity.

ZnO-Graphene material has been proven to show the effect of memristive behaviour. Consequently, a good memristive performance in devices of such materials has the potential in non-volatile memory applications. However, little is known about the significance of nanostructure in making the devices more conductive, thereby improving their performance. Here, we show the electrical, optical and morphological properties of ZnO decorated Graphene film for memristive device by using dip-coating method. Nanoflake structure was observed in samples that had been immersed 5 times for 30 seconds and annealed each time at 250°C for 10 minutes. These samples have higher current than that of samples without the nanostructure. The overall results demonstrate that the nanostructure ZnO and Graphene have greatly improved the current by 16 × 106 order of magnitude, thereby giving rise to improved memristive behaviour with resistance ratio of 1.18.
zno -石墨烯材料已被证明具有忆阻效应。因此,在这种材料的器件中具有良好的记忆性能,在非易失性存储器应用中具有潜力。然而,人们对纳米结构在提高器件导电性从而改善其性能方面的重要性知之甚少。本文采用浸涂法研究了ZnO修饰石墨烯薄膜的电学、光学和形态学特性。样品浸泡5次30秒,每次250℃退火10分钟,观察到纳米片结构。这些样品比没有纳米结构的样品具有更高的电流。总体结果表明,ZnO和石墨烯的纳米结构使电流大大提高了16 × 106个数量级,从而提高了电阻比为1.18的记忆电阻行为。

Traffic congestion is a major issue that happens across urban cities around the world. In 2015, annual economic losses of Malaysia caused by traffic congestion is estimated about RM20 billion. Fixed cycle traffic light system (TLS) is first introduced on road intersection to solve traffic congestion. However, fixed cycle TLS in unable to cope with dramatically increase of registered vehicles. In this paper, development of Internet of Things (IoT) device for traffic management system is proposed. An Intel Edison collects real-time traffic flow and communicate with Microsoft Azure IoT cloud server. The cloud server assign priorities to each road bound based on their current traffic volume. Green light phase time (GLPT) is then calculated utilizing a dynamic algorithm. Simulation results showed that dynamic cycle TLS reduces queue length and waiting time on the road intersection by 68% and 67% respectively. Additionally, a monitoring application is designed to ease traffic officer in monitoring real-time traffic flow.
交通拥堵是发生在世界各地城市的一个主要问题。2015年,马来西亚每年因交通拥堵造成的经济损失估计约为200亿令吉。为了解决交通拥堵问题,首次在十字路口引入了固定周期交通灯系统。然而,固定周期TLS无法应对急剧增加的注册车辆。本文提出了一种用于交通管理系统的物联网设备。英特尔Edison收集实时交通流量,并与微软Azure物联网云服务器通信。云服务器根据当前的交通量为每条道路分配优先级。然后利用动态算法计算绿光相位时间(GLPT)。仿真结果表明,动态循环TLS使交叉口排队长度和等待时间分别减少68%和67%。此外,还设计了一个监控应用程序,以方便交通官员监控实时交通流量。

Government Human Capital Management is activities to manage government human capital based on their performance and competency. These processes were managed by three government institution (MENPAN, LAN, and BKN). These institutions should coordinate and collaborate to perform their duties and function. Knowledge management (KM) can enhance collaboration among individual and institution with sharing and transferring their organizational knowledge. KM is not easy to implement, some strategic issues, problems and challenges must be considered in KM implementation for government human capital management. This research aims to determine preliminary studies for KM implementation of government human capital management. It aims to identify strategic issue and problems in government ministries. Deep interview and observation are conducted to collect the data from three government institution. Qualitative research used to discover some findings align with respondent experiences. While, content analysis and fishbone analysis are used to analyze the data. The strategic issues are aim to developed the professional human resource and organization. While, findings problem consist of sixteen problems which represent in fishbone diagram into four categories there are people, organization, policies and technologies. Those problems cause a main effect that is unprofessional people and organization.
政府人力资本管理是根据政府人力资本的表现和能力对其进行管理的活动。这些过程由三个政府机构(MENPAN、LAN和BKN)管理。这些机构应协调和合作履行其职责和职能。知识管理可以促进个人和机构之间的协作,实现组织知识的共享和转移。KM的实施并不容易,政府人力资本管理实施KM必须考虑一些战略性问题、问题和挑战。本研究旨在为政府人力资本管理实施知识管理进行初步研究。它旨在确定政府部门的战略问题和问题。通过深度访谈和观察,收集了三家政府机构的数据。定性研究用于发现一些与受访者经验一致的发现。数据分析主要采用内容分析和鱼骨分析。战略问题的目标是发展专业化的人力资源和组织。而发现问题则由鱼骨图中的16个问题组成,分为人、组织、政策和技术四大类。这些问题造成的主要影响是人员和组织不专业。
