Even though various dorsal hand vein pattern extraction techniques have been proposed for biometric identification, there remains considerable room for performance. This paper describes dorsal hand vein recognition using statistical and Gray Level Co-occurrence Matrix (GLCM) based features extraction techniques and artificial neural networks (ANN). For this purpose, 240 images of 80 users were obtained from Bosphorus Hand Vein Database. The images were first pre-processed by cropping region of interest (ROI), before the application of mean filtering, contrast enhancing and histogram equalizing. The ROI was then segmented by implementation of binarization method. The statistical and GLCM features were then extracted from the segmented ROI. These extracted features were sent to ANN for classification of the images. The training result shows that the proposed technique is able to recognize dorsal hand vein pattern with with considerably high accuracy of 99.32%.
尽管各种手背静脉模式提取技术已被提出用于生物识别,但仍有相当大的发挥空间。本文介绍了基于统计和灰度共生矩阵(GLCM)的特征提取技术和人工神经网络(ANN)的手背静脉识别。为此,我们从博斯普鲁斯手静脉数据库中获取了80名用户的240张图像。首先对图像进行裁剪感兴趣区域(ROI)预处理,然后进行均值滤波、对比度增强和直方图均衡化。然后采用二值化方法对ROI进行分割。然后从分割的ROI中提取统计特征和GLCM特征。这些提取的特征被发送给人工神经网络进行图像分类。训练结果表明,该方法能够识别手背静脉模式,准确率达到99.32%。

The requirement to use low carbon-emitting power plants promotes increased utilization of renewable energy source. Photovoltaic (PV) as a modular generation is relatively easy to implement compared to the other renewable energy plants. In 2017, PV usage hits 100GW, globally. The safety of photovoltaic modules appears to be an issue with the growing usage of photovoltaic, as PV modules will face various modes of faults during the operation. Nearly 50 % of the total fault is the hot spot that is very difficult to locate in a largescale PV field. The latest method requires up to 105 days to detect hotspot in a 15 MW PV generation with an area of 30 hectares and made of 63000 modules (contains millions of cells). Those methods which cannot quickly and continuously detect the fault can degrade and burn the module. Therefore, a fast detection method is needed to prevent the catastrophic failure of PV modules. Thermal imaging using fish eye lens is promised to face this problem. It has wide field of view so that the wide area PV farm could be monitored simultaneously. However, fish eye lens has non linear projections which affect the image shape. Therefore, in this paper, the simulation to identified PV image characteristic that created by fish eye lens has been performed. The results show that there are some parameter combinations which can create a clear image without any overlapping. Also, the result show the length characteristic of PV image which can be used to defined the requirement of thermal sensor sensitivity.
使用低碳排放发电厂的要求促进了可再生能源的利用。与其他可再生能源工厂相比,光伏(PV)作为模块化发电相对容易实施。2017年,全球光伏使用量将达到100GW。随着光伏的日益普及,光伏组件的安全问题日益突出,因为光伏组件在运行过程中会面临各种形式的故障。在大型光伏电站中,近50%的断层是难以定位的热点。最新的方法需要长达105天的时间来检测一个面积为30公顷、由63000个模块(包含数百万个电池)组成的15兆瓦光伏电站的热点。不能快速连续检测故障的方法会导致模块降级和烧毁。因此,需要一种快速的检测方法来防止光伏组件的灾难性故障。鱼眼透镜热成像技术有望解决这一问题。视野开阔,可实现对广域光伏电站的同步监控。然而,鱼眼透镜存在非线性投影,影响像形。因此,本文对鱼眼透镜产生的PV图像特征进行了仿真识别。结果表明,采用一定的参数组合可以得到清晰的无重叠图像。结果表明,PV图像的长度特征可用于确定热传感器灵敏度的要求。

Games have existed since time immemorial and have proved to significantly change people’s mentality and attitudes towards countless scenarios. Games can be either physical or mental, for example, sports and chess. Games have developed over the past decades, having gone through significant changes via digitization. Games nowadays are at everyone’s disposal since almost everyone possesses a smartphone. Videogame such as PUBG, Call of Duty mobile, Fortnite, and more are very addictive games that consume a lot of our time daily. Although games are ‘time wasters’, we should acknowledge the one thing that games offer: this is the constant testing, and learning a simple game engages the brain proves that games are an asset in mental development and thus gamification can be used to provide a fun learning environment. In this article, we discuss how gamification has been implemented in various applications over the years, people’s take on gamification and gamified apps from a survey and interview conducted, and thereafter design a student-oriented gamified study app, Gamesy, that makes use of game elements to improve performance in school and change/improve study habits in a game environment via progressive game design. With this, better performance may be realized in the tertiary education level, university, and college.
游戏自古以来就存在,并被证明能够显著改变人们对无数场景的心态和态度。游戏可以是身体上的,也可以是精神上的,比如体育和象棋。在过去的几十年里,游戏经历了数字化带来的巨大变化。如今,几乎每个人都拥有智能手机,所以每个人都可以随意使用游戏。像《绝地求生》,《使命召唤》手机版,《堡垒之夜》等电子游戏都是非常令人上瘾的游戏,每天都会消耗我们大量的时间。虽然游戏是“浪费时间的东西”,但我们应该承认游戏提供的一件事:这是持续的测试,学习一款简单的游戏可以让大脑参与其中,这证明了游戏是智力发展的资产,因此游戏化可以用来提供有趣的学习环境。在本文中,我们将讨论多年来游戏化是如何在各种应用中实现的,人们通过调查和访谈对游戏化和游戏化应用的看法,然后设计一款面向学生的游戏化学习应用Gamesy,它利用游戏元素来提高学生在学校的表现,并通过渐进式游戏设计来改变/改善游戏环境中的学习习惯。有了这个,更好的表现可能会在高等教育水平,大学和学院实现。

In the field of aviation, Unmanned Arial Vehicles (UAV) play a prominent role as they can be controlled remotely by a ground based controller and some have the ability to fly autonomously using an autopilot system. They can be employed to perform tasks like surveillance in high altitude, inspection in a large area, transportation and they can be even used for some military activities. Landmines are common threats to the military, civilians and animals. Innocent people lose their lives or limbs to these deadly weapons every year. MQUAD is a hardware and software solution to detect landmines in a landmine contaminated area. It can alert the demining squad about the exact location of the detected landmine. All the parts for quadcopter frame are 3D designed and printed using PLA material to reduce the overall weight of the system. Flight controller for M-QUAD is developed using a gyroscope and accelerometer module and a microcontroller. Radio Frequency (RF) receiver connected to Flight Controller controls the movements of the quadcopter. Pitch, Roll, Yaw and Throttle movements of the quadcopter are controlled by a RF Transmitter. An IOT based metal detector is developed and employed to detect landmines and the sharp metal fragments inside them. A GPS Location Alerting system is designed to share the location of the detected Landmines with the demining squad. M-QUAD was hovered manually to detect landmine like metal structures and the location of the detected metal items were observed with the help of the Mobile Application. Three detection coils with different diameters were employed during the experiment to observe the change in detection range for each coil. Detection coil of 14cm diameter detects up to a depth of 25cm. This system will serve as a useful tool to eradicate landmines and save innocent lives.
在航空领域,无人驾驶飞行器(UAV)发挥着突出的作用,因为它们可以通过地面控制器远程控制,有些具有使用自动驾驶系统自主飞行的能力。它们可以用于执行高空监视、大面积检查、运输等任务,甚至可以用于一些军事活动。地雷是对军队、平民和动物的共同威胁。每年都有无辜的人因这些致命武器而失去生命或四肢。MQUAD是一种硬件和软件解决方案,用于探测地雷污染区域的地雷。它可以提醒排雷小组关于探测到的地雷的确切位置。四轴飞行器框架的所有部件均采用PLA材料进行3D设计和打印,以减轻系统的整体重量。M-QUAD的飞行控制器采用陀螺仪、加速度计模块和微控制器。无线电频率(RF)接收器连接到飞行控制器控制四轴飞行器的运动。四轴飞行器的俯仰、滚转、偏航和油门运动由射频发射器控制。开发了一种基于物联网的金属探测器,用于探测地雷及其内部的尖锐金属碎片。GPS定位警报系统设计用于与排雷班共享探测到的地雷的位置。M-QUAD手动悬停探测类似地雷的金属结构,并在移动应用程序的帮助下观察探测到的金属物体的位置。实验中使用了三个不同直径的检测线圈,观察每个线圈检测范围的变化情况。检测线圈直径14cm,检测深度可达25cm。这一制度将成为消除地雷和拯救无辜生命的有用工具。

In this paper, a microstrip patch antenna is proposed to be implemented for 5G broadband wireless communication. The single element antenna was designed to operate in the Priority 1 spectrum 3.5 GHz band set by the Malaysian Communications and Multimedia Commission (MCMC). The antenna was built on a Rogers RT5880 substrate with a dimension of 44.1 mm x 35.1 mm x 1.57 mm, which has a dielectric constant ($varepsilon_{r}$) of 2.2 and loss tangent ($delta$) of 0.0009. The simulated performances of the antenna achieved a return loss of 26.347 dB at 3.5 GHz, bandwidth of 641.2 MHz ranging from 3.282 GHz to 3.910 GHz, and a gain with value of 3.68 dBi. The fabricated antenna was measured using Virtual Network Analyzer (VNA) for real world measurement, and the return loss at 3.5 GHz exhibits a value of 12.146 dB. The error was identified and simulated in CST-MWS software, and preventive measures have been listed.

Graphene oxide (GO) and reduced graphene oxide (rGO) have successfully synthesized using modified Tour’s method with end product having rapid purification rate, hydrophobic condition and conductive material. Prominent green reducing agent namely ascorbic acid has used in the GO sample preparation and act as reductant which help removal of oxygen containing functional group hence, resultant of rGO. In this investigation, the GO purification rate has accelerated by help of sodium hydroxide (NaOH) in function of washing agent with only 3 cycle’s wash. Raman spectroscopy results show that the synthesized GO and rGO samples yield in the range of 1349.33 cm$^{-1}$ (D band) to 1571.35 cm$^{-1}$ (G band) of Raman peak, respectively. A narrow and sharp Raman peak with high intensity of rGO sample has indicates it having a better quality as compared to GO sample. Contact angle measurement reveal the large angle obtained from rGO sample which are 72.8° on left hand side and 65.0° for right side, correspondingly have confirmed it is more hydrophobic than GO which attained contact angle of 52.5° on both sides. Surface morphology examined by Field Emission Scanning Electron Microscope (FE-SEM) show that both samples that diluted with deionized (DI) water have a loose sponge which similar to a thin wrinkle sheet in structure that suggest it has well exfoliated by using modified Tour’s method. On the other hand, produced samples that not diluted with DI water has tightly packed, corrugated and crumpled in form. Results from Energy Dispersive Spectroscopy (EDS) measurement has confirmed that oxygen-containing functional group have been removed from rGO sample by having higher calculated carbon / oxygen (C / O) in quotient with 3.09 as compared to GO sample with 1.43 which based on the atomic percentage of C/O. The significant reduction of resistance value from rGO sample with $33.41 times 10^{4}Omega$ as compared to GO with $41.18 times 10^{6} Omega$ have leading it to obtained better conductivity with $4.77 times 10^{-7}$ S / cm in comparison to GO sample with $3.86 times 10^{-9}$S / cm. Thus, this modified Tour’s method with the usage of green reductant agent has potential to be used in producing sensing device applications.
采用改进Tour的方法成功合成了氧化石墨烯(GO)和还原氧化石墨烯(rGO),最终产物具有纯化速度快、疏水条件和导电材料。著名的绿色还原剂抗坏血酸已用于氧化石墨烯样品制备,并作为还原剂,帮助去除含氧官能团,从而得到氧化石墨烯。在本研究中,氢氧化钠(NaOH)作为清洗剂的作用下,只需3个循环的洗涤,就能加快氧化石墨烯的净化速度。Raman光谱结果表明,合成的GO和rGO样品的Raman峰产率分别在1349.33 cm$^{-1}$ (D波段)至1571.35 cm$^{-1}$ (G波段)范围内。还原氧化石墨烯样品的拉曼峰窄而尖锐,强度高,表明其质量优于氧化石墨烯样品。接触角测量显示,rGO样品获得的大角为左侧72.8°,右侧65.0°,相应地证实了它比两侧接触角为52.5°的氧化石墨烯更疏水。用场发射扫描电镜(FE-SEM)观察两种样品的表面形貌,结果表明,用去离子水稀释后的样品表面呈松散的海绵状,结构类似于薄的皱褶片,表明用改进的Tour’s方法进行了很好的剥离。另一方面,未用去水稀释的样品包装紧密,呈波纹状和皱褶状。能量色散光谱(EDS)测量结果证实,氧化石墨烯样品的含氧官能团被去除,计算出的碳/氧(C /O)商为3.09,而氧化石墨烯样品的碳/氧(C /O)商为1.43(基于C/O的原子百分比)。与$41.18 $ 10^{4}Omega$相比,$33.41 乘以10^{6}Omega$的氧化石墨烯样品的电阻值显著降低,使其获得了比$3.86 乘以10^{-9}$S / cm的氧化石墨烯样品更好的电导率,为$4.77 乘以10^{-7}$ S / cm。因此,这种使用绿色还原剂的改进Tour的方法具有用于生产传感器件应用的潜力。

Wireless network-on-chip (WiNoC) was introduced to enhance the efficiency and performance of network-on-chip (NoC). WiNoC architecture efficiency depends on a good choice of virtual channels (VC), subnets and routing algorithm. This work investigates the effect of VC, subnet size and routing on WiNoC performance efficiency and energy at varying packet injection rate (PIR) at different traffic distribution and the number of cores (64, 256 and 1024). This paper showed that subnets have a more significant impact on the performance efficiency of network architecture in WiNoC. However, VCs only improve energy consumption in NoC while it has little effect on WiNoC. The research evaluation was done using Noxim simulator, which is based on system C.
引入无线片上网络(WiNoC)是为了提高片上网络(NoC)的效率和性能。WiNoC架构的效率取决于虚拟信道(VC)、子网和路由算法的选择。本文研究了在不同流量分布和核数(64、256和1024)下,不同分组注入率(PIR)下,VC、子网大小和路由对WiNoC性能效率和能量的影响。研究表明,在WiNoC中,子网对网络架构的性能效率影响更为显著。然而,风险投资只改善了NoC的能源消耗,而对WiNoC的影响很小。利用基于C系统的Noxim仿真器进行了研究评价。

Industry Revolution 4.0 transforms product design and fabrication. It revolutionize how manufacturing operates and performs maintenance. Information Technology plays a crucial role in IR4.0 that drives the digitalization of manufacturing. The combination of Information Technology with Operational Technology forms the core of Smart Manufacturing. It works beyond automation and machine-to-machine communications. Among the benefits of IR4.0 are enhanced efficiency in production, mass-customization of product, zero downtime, extended tool life and energy efficiency. Robotics is an ideal smart technology of IR4.0. Current trend in Robotics introduces the deployment of collaborative robot, for SME. However, monitoring and interaction with such system comes with additional challenges especially in large-scale deployment. Dashboard application becomes more important for such system to have a better management. Most of the existing applications are managed in an isolated system even within the same factory, thus make it difficult to maintain and troubleshoot if problems occur. In this paper, we proposed a design of centralized dashboard application with interactive 3D visualization and informative visualization for managing and troubleshooting COBOT System.
工业革命4.0改变了产品设计和制造。它彻底改变了制造操作和维护的方式。信息技术在推动制造业数字化的工业4.0中发挥着至关重要的作用。信息技术与操作技术的结合构成了智能制造的核心。它的作用超越了自动化和机器对机器的通信。IR4.0的优点包括提高生产效率、大规模定制产品、零停机时间、延长工具寿命和提高能源效率。机器人技术是工业4.0理想的智能技术。机器人技术的当前趋势介绍了协作机器人的部署,为中小企业。然而,监控和与此类系统的交互带来了额外的挑战,特别是在大规模部署中。为了更好地管理这类系统,仪表板应用变得更加重要。大多数现有的应用程序都是在一个孤立的系统中管理的,甚至在同一个工厂内,因此,如果出现问题,很难维护和排除故障。本文提出了一种具有交互式三维可视化和信息可视化的集中式仪表板应用程序,用于COBOT系统的管理和故障排除。

Renewable energy had taken a significant role to supply electricity nowadays. The vital fact about renewable energy is the energy infinitely replenished. Solar energy is the most popular source in Malaysia compared to wind energy, hydropower, biogas, geothermal, and others. Unfortunately, some of the renewable energy have not widely used even though they have a high capability to supply electricity. As Malaysia is the world’s second-largest producer of Palm Oil Mill Effluent (POME), hence it can be used to produce biogas. A study has been carried out to explore biogas ability to supply electricity in Malaysia. This study has been conducted in several contributing factors, namely geographical distribution, technology involved, and economic analysis. These factors will prove the feasibility of electrification via biogas. The review has been done by collecting the information and data from the previous studies such as journal and visits to official websites and related authorities that shows the current data and usage of biogas. The results show that biogas generation activity has been primarily promoted and produced due to sufficient waste products and modern technology used. In the last decade, the Malaysian government had actively involved in fostering biogas and built economy catalyst to pursue biogas by involving the private sector.
可再生能源在当今的电力供应中扮演着重要的角色。关于可再生能源的一个重要事实是能源可以无限地补充。与风能、水电、沼气、地热等能源相比,太阳能是马来西亚最受欢迎的能源。不幸的是,尽管一些可再生能源具有很高的供电能力,但它们并没有得到广泛的应用。由于马来西亚是世界上第二大棕榈油厂废水(POME)的生产国,因此它可以用来生产沼气。马来西亚开展了一项研究,以探索沼气供电的能力。这项研究是在地理分布、涉及的技术和经济分析等几个因素下进行的。这些因素将证明沼气电气化的可行性。本次审查是通过收集以往研究的信息和数据来完成的,例如期刊和访问官方网站和相关部门,这些信息和数据显示了目前的数据和沼气的使用情况。结果表明,由于废弃物充足和现代技术的使用,沼气生产活动得到了初步的促进和生产。近十年来,马来西亚政府积极参与沼气的培育,并通过私营部门的参与建立了沼气发展的经济催化剂。

In this paper, a unique logo antenna is proposed for the 5G applications, which can be used to monitor the body. The antenna was designed to mimic the shape of a unique logo. The overall size of the logo antenna is $20times 20times 1.6mathrm{m}mathrm{m}^{3}$, which makes it the smallest logo up to date in the literature. It works on the 2.9-7.9 GHz, unlicensed future 5G band. In free space, the bandwidth (BW), the reflection coefficient (Sii), and the gain of 4.981 GHz, -27.32dB, and 2.75 dBi were achieved, respectively. While on-body, the achievable values are 4.8099 GHz, -32dB, and 5.0 dBi, respectively. The antenna showed an omnidirectional radiation pattern for off and on-body applications. The specific absorption rate (SAR) is limited to $leq$2W/KG in the full band. The simulated and measured results are nearly matched, except some measured results are changed due to the fabrication tolerance.
本文针对5G应用,提出了一种独特的标识天线,可用于人体监控。天线被设计成模仿一个独特标志的形状。标志天线的整体尺寸为$20times 20times 1.6mathrm{m}mathrm{m}^{3}$,这使其成为文献中最小的标志。它工作在2.9-7.9 GHz,未经许可的未来5G频段。在自由空间中,带宽(BW)、反射系数(Sii)和增益分别达到4.981 GHz、-27.32dB和2.75 dBi。而在体上,可实现值分别为4.8099 GHz, -32dB和5.0 dBi。该天线显示了一个全方位的辐射模式,为off和on-body应用。全波段的比吸收率(SAR)限制为$leq$ 2W/KG。仿真结果与实测结果基本吻合,但由于制造公差的影响,实测结果存在一定的偏差。
