Currently, the traditional agriculture is being transformed into smart agriculture using the Internet of Things (IoT) technology. An agriculture service platform is being developed to help with environmental monitoring and to improve agricultural management. Various climate condition parameters are vital to be monitored for agriculture for ensuring optimal growth conditions. The crop production regulation, and climate change has negative impact on agriculture and food production due to excess rainfall, temperature changes, and other associated environmental variations. Different type of plants has its own need of fertilization and water where poor management of water and fertilization will lead to unhealthy crops and shorten their lifespan. The goal of this study is to design and develop a plant management system based on sensors and microcontroller. The input of the system includes pH, temperature, and soil moisture alongside real-time clock module. The system uses LoRa for data transmission that will allow the data to be transmitted up to 1 km distance. The system will optimize the plant watering leading to more efficient water usage. Moreover, this system will have a Graphical User Interface (GUI) that will allow user to provide plant watering schedule for the user. This system has been successfully tested based on several experiments. This system can be used for both indoor and outdoor plants
目前,传统农业正在利用物联网技术向智慧农业转型。正在开发一个农业服务平台,以帮助进行环境监测和改善农业管理。各种气候条件参数的监测对农业至关重要,以确保最佳的生长条件。作物生产调节和气候变化对农业和粮食生产产生负面影响,原因是降雨过多、温度变化和其他相关的环境变化。不同类型的植物都有自己对施肥和水的需求,而施肥管理不善将导致作物不健康并缩短其寿命。本研究的目标是设计和开发一个基于传感器和单片机的工厂管理系统。系统的输入包括pH值、温度和土壤湿度以及实时时钟模块。该系统使用LoRa进行数据传输,将允许数据传输到最远1公里的距离。该系统将优化植物浇水,从而更有效地利用水。此外,该系统将具有图形用户界面(GUI),允许用户为用户提供植物浇水时间表。该系统经过多次实验验证,取得了良好的效果。该系统可用于室内和室外植物

Spasticity is a feature of altered skeletal muscle performance with the constraint of tendon reflex activity. The level of fatigue in spastic patients is difficult to be measured without a high-end measurement system. This work aims to evaluate the effectiveness of spasticity robotic arms robot and surface Electromyogram (sEMG) on the observation and measurement of the arms-hand skill in stroke patients during rehabilitation. The result will provide an overview of criteria and conditions for the implementation of the technology in clinical practice. This study assesses the fatigue level among spasticity patients based on the localized muscle voluntary of the patient measured using the spasticity robotic arms (SRA) and Joint Analysis of EMG Spectrum and Amplitude (JASA). The data signal was changed to spectrum and medium frequency to evaluate the fatigue where the non-implant surface electromyogram was recorded in each motor unit in real-time. The analysis JASA method able to shows the level of fatigue in a multi-degree range of motion. The sampling data signal was integrated with therobotic therapy to overcome the over-exercise or lack of training during rehabilitation. The five axes of SRA can assist the therapy to perform in multi-degree rotation with the robust flexion-extension and abduction-adduction rotations. The accuracy between RSA and LSA is 0.003 ± 0.0910 of amplitude frequency against ROM. Further investigation in Medium Frequency (MDF) is 32.81 ± 45.341 revolution between RSA and LSA is 93.9% accuracy. The effect between RSA and LSA kinematic ROM is 0.6875 ± 9.0401accuracy in 95% between each assessment in MDF. The revolute and prismatic motion was able to overcome the difficulty of spasticity patient range of motion because of stroke. The Surface EMG for non-invasive assessment of muscles (SENIAM) assessment Fugl-Meyer Assessment (FMA) is used to guide the active-passive assisted motion. The fatigue detection method was evaluated based on eight male and eight female subjects. The process of the exercise made the patient fatigue because due to the muscle unable to carry the burden of the force from the SRA robot in 95% cases for RSA and 75% in LSA. The success of work proves the JASA method and SRA robot therapy able to assist to determine the level of fatigue among spasticity patients.
痉挛是骨骼肌功能改变与肌腱反射活动约束的特征。如果没有高端的测量系统,很难测量痉挛患者的疲劳程度。本研究旨在评估痉挛机械臂和表面肌电图(sEMG)在脑卒中患者康复过程中手臂-手技能观察和测量的有效性。结果将提供标准和条件的概述,在临床实践中实施的技术。本研究基于痉挛机械臂(SRA)和关节肌电信号频谱和振幅分析(JASA)测量的局部肌肉自愿来评估痉挛患者的疲劳水平。数据信号转换为频谱和中频评估疲劳,实时记录各运动单元非植入体表面肌电图。分析JASA方法能够显示多度运动范围内的疲劳程度。采样数据信号与机器人治疗相结合,克服了康复过程中过度运动或缺乏训练的问题。SRA的五个轴可以帮助治疗进行多度旋转,具有强健的屈-伸和外展-内收旋转。在中频(MDF)中,RSA和LSA的幅频相对ROM的精度为32.81±45.341转,精度为93.9%。在MDF中,RSA和LSA运动学ROM之间的影响为0.6875±9.0401,每次评估之间的准确率为95%。旋转和移动能够克服痉挛患者的运动范围的困难,因为中风。采用无创肌表肌电信号(SENIAM)评估Fugl-Meyer评估(FMA)来指导主动-被动辅助运动。以8名男性受试者和8名女性受试者为对象,对疲劳检测方法进行了评价。在运动过程中,95%的RSA和75%的LSA患者由于肌肉无法承受来自SRA机器人的力而感到疲劳。工作的成功证明了JASA方法和SRA机器人治疗能够帮助确定痉挛患者的疲劳程度。

Conventional fossil fuel generation releases high amount of carbon dioxide and contributed to the climate change problem. Hence, the use of renewable energy sources is important to mitigate the greenhouse gasses emissions. Remote or rural areas relies heavily on diesel generations for electricity due to no grid connection. Therefore, a microgrid system with renewable resources has high potential for implementation in these areas.  This paper discusses on the hybrid renewable energy system design for a village in Selangor, Malaysia. The load profile data collected based on survey and interview with the locals. Meanwhile, the solar radiation and temperature data were obtained from NASA POWER database. The hydropower resource data was obtained through site visit at the location. HOMER software was used to simulate and determine the most optimal hybrid renewable energy system. Additionally, sensitivity analysis was conducted to identify effect of growth in load profile with respect to the optimal configuration. The optimization results shows that PV-hydro-grid is the most optimal system. It has lower Net Present Cost with higher renewable penetration compared to other configurations.
传统的化石燃料发电释放出大量的二氧化碳,加剧了气候变化问题。因此,可再生能源的使用对减少温室气体排放至关重要。由于没有电网连接,偏远或农村地区严重依赖柴油发电。因此,具有可再生资源的微电网系统在这些地区具有很高的实施潜力。本文讨论了马来西亚雪兰莪州一个村庄的混合可再生能源系统设计。负荷概况数据是通过对当地居民的调查和访谈收集的。同时,从NASA POWER数据库获取太阳辐射和温度数据。水电资源数据通过实地考察获得。采用HOMER软件对混合可再生能源系统进行仿真,确定最优方案。此外,还进行了敏感性分析,以确定负载分布的增长对最优配置的影响。优化结果表明,光伏-水电并网是最优系统。与其他配置相比,它具有较低的净当前成本和较高的可再生渗透率。
