Assistive exoskeletons are rapidly being developed to collaborate with humans, and the demand for the safety of human-robot interaction has become more crucial. Series elastic actuators (SEAs) have recently been developed for various possible advantages, such as providing a safe human-robot interaction, reducing the impacts' effects, and increasing energy efficiency. However, achieving good dynamic performances of SEAs is still challenging, especially in fulfilling the high bandwidth with good compliance. In this rapidly growing research field, the actuation system involving the storage device combined with the rotary series elastic actuator (ES-RSEA) is being investigated to exploit the biomechanical energy while maintaining compliance features. In this article, the modeling and control design of the energy storage rotary series elastic actuator (ES-RSEA) for the lumbar support exoskeleton is proposed, and its dynamic performances are analyzed. The ES-RSEA was designed to store kinetic energy during lifting tasks and generate assistive torque while maintaining excellent compliant characteristics. The dynamic performances and characteristics of ES-RSEA are presented in terms of force sensitivity, level of compliance, transmission ratio, and bandwidth. Simulation studies indicate that the actuator can provide excellent dynamic performance through its high bandwidth (12.44 Hz) and high force sensitivity. At the same time, it shows excellent compliance and good torque transmissibility in the low-frequency range. A PID controller can achieve high torque tracking performance and good dynamic response with a root-mean-square (RMS) error of 0.1 N.m. This article demonstrates the excellent performance and characteristics of ES-RSEA to guarantee compliance and high response to prevent injury of undesired human movements.
辅助外骨骼正在迅速发展,以与人类合作,对人机交互的安全性的需求变得更加重要。系列弹性致动器(SEAs)最近被开发出来,具有各种可能的优势,例如提供安全的人机交互,减少撞击的影响,提高能源效率。然而,实现良好的动态性能仍然是一个挑战,特别是在满足高带宽和良好的顺应性方面。在这一快速发展的研究领域中,人们正在研究将存储装置与旋转系列弹性驱动器(ES-RSEA)相结合的驱动系统,以在保持柔顺特性的同时利用生物力学能。本文提出了用于腰椎支撑外骨骼的储能旋转系列弹性驱动器(ES-RSEA)的建模与控制设计,并对其动态性能进行了分析。ES-RSEA的设计目的是在起重任务期间存储动能并产生辅助扭矩,同时保持良好的顺应特性。从力灵敏度、柔度、传动比和带宽等方面介绍了ES-RSEA的动态性能和特性。仿真研究表明,该驱动器具有高带宽(12.44 Hz)和高力灵敏度,能够提供良好的动态性能。同时,在低频范围内具有良好的柔度和传递力矩性能。PID控制器可以实现高扭矩跟踪性能和良好的动态响应,均方根误差为0.1 N.m。本文展示了ES-RSEA的优异性能和特点,保证了顺应性和高响应,防止了人体意外运动的伤害。

Orthomosaic is a map derived from numbers of overlapped aerial images that are stitched together using photogrammetry software. Orthomosaic can be used as an analysing tool to extract topographic features and monitoring applications. The accuracy of any photogrammetry product is important and can be dictated by various reasons. One of the prominent factors is the utilization of Ground Control Point (GCP). GCPs is known as sets of points in the study area that were established to provide aerial images with known coordinates through georeferencing process. The optimum GCP distribution is at the edge of the study area. However, it is sometimes impossible to access several areas of the mapping area due to unexpected prohibitions. The only option is to establish the point at the area where they can access it. Different numbers and distribution of GCP will contribute to the changes in accuracy. For this study, twelve points were established using GNSS observation. These points are utilized as either GCP or Check Point (CP). The number of GCP for each processing differs from three GCPs to six GCPs. Each number of GCP were distributed either at the edge or centre of the area. Edge distribution is supported with several GCPs at the centre. This study utilized a multi-rotor drone with an integrated camera for data acquisition. The method of analysis for this study is by comparing the coordinates of CP and computing the planimetric and vertical RMSE from each orthomosaic. This study found that the best GCP configuration with optimum accuracy is six GCPs with edge distribution with the RMSE of 2.9 cm and 4.4 cm for planimetric and vertical accuracy, respectively. This study helps to plan the task to establish the GCPs thoroughly to ensure great accuracy can be achieved regardless of the circumstances.
正射影图是由使用摄影测量软件拼接在一起的许多重叠的航空图像衍生而成的地图。正射影可作为一种分析工具,用于提取地形特征和监测应用。任何摄影测量产品的准确性都很重要,并且可以由各种原因决定。其中一个突出的因素是地面控制点(GCP)的利用。gcp被称为研究区域内的点集,通过地理参考过程提供具有已知坐标的航空图像。GCP的最佳分布在研究区的边缘。然而,由于意想不到的禁令,有时无法进入映射区域的几个区域。唯一的选择是在他们可以访问的区域建立一个点。GCP的数量和分布的不同会导致精度的变化。本研究利用GNSS观测建立了12个点。这些点被用作GCP或检查点(CP)。每个处理的GCP数量从3个到6个不等。每个数目的GCP分布在区域的边缘或中心。边缘分布支持几个gcp在中心。本研究利用多旋翼无人机与集成摄像头进行数据采集。本研究的分析方法是通过比较CP的坐标并计算每个正交的平面和垂直RMSE。研究发现,最优精度的GCP配置为6个边缘分布的GCP,平面和垂直精度的RMSE分别为2.9 cm和4.4 cm。本研究有助于全面规划建立gcp的任务,以确保在任何情况下都能达到很高的准确性。

Lecturers must conduct research and publish their findings. The reason is obvious, it is a medium of knowledge dissemination and as part of their Key Performance Indicators (KPIs). However, it is difficult for administrators to analyze the performance and publication output of all academic staff because the information available on the Scopus® website is displayed individually. To overcome this problem, administrators often employ dedicated staff to manually enter this information in Google spreadsheet, so that the information is available on demand. However, the information may not be the latest as the data on the Scopus® website is constantly updated when there are new publications. Therefore, an automatic retrieval system was developed using Python. The system automatically queries data from the Scopus® website using the Scopus® API. Then, the results will be saved to two different locations which are the Google spreadsheet and the MySQL database. The Google spreadsheet stores current publications while the database contains all publications by the academic staff. This mechanism allows administrators to monitor the performance and output of all academic staff of the School of Electrical Engineering through Google spreadsheet and the associated website.

One of the most popular lean manufacturing techniques for calculating cycle time (CT) and lead time (LT) in the process flow from customer order to shipment is value stream mapping (VSM). Events in the flow that are value-added (VAA) and non-value-added (NVAA) must be identified and recorded in the VSM. Only a small number of studies, meanwhile, have considered risk management when determining lead times. With (minimum, most-likely(mean), maximum) values for each CT/LT and Risk Assessment-Failure Mode and Effect Analysis (RA-FMEA) for all hazards reported, Variable VSM (V-VSM) will be used in this report. The model will be simulated using Monte Carlo simulation with @Risk software for a more accurate outcome. Each process should be described by the best-fit probability distribution before the simulation. The management may finalize the current and future VSMs, which would show all pertinent elements. In a small- and medium-sized food manufacturing company that produces pre-mixed powder drinks, this approach will be put to the test. As a result of this study, the management should take into account the (minimum, most-likely(mean), maximum) time values of total CT/LT and Risk while preparing the raw material order, VAA/NVAA activities in the production line, Work in Progress (WIP), process layout, and shipment schedule. The focus of this paper however, will be on the validation of Monte Carlo simulation performed with the @ Risk software using the developed V-VSM and RA-FMEA model. The result obtained is compared to the traditional VSM’s result.
价值流映射(VSM)是计算从客户订单到出货过程中周期时间(CT)和交货时间(LT)的最流行的精益制造技术之一。需要在VSM中识别增值流和非增值流中的事件,并将其记录在VSM中。与此同时,只有少数研究在确定交货期时考虑了风险管理。每个CT/LT的(最小值,最可能值(平均值),最大值)值和所有报告的风险评估-失效模式和影响分析(RA-FMEA),将在本报告中使用可变VSM (V-VSM)。该模型将使用蒙特卡罗模拟和@Risk软件进行模拟,以获得更准确的结果。在模拟之前,每个过程都应该用最佳拟合概率分布来描述。管理部门可以最终确定当前和未来的vsm,它将显示所有相关因素。在一家生产预混合粉末饮料的中小型食品制造公司,这种方法将得到检验。作为这项研究的结果,在准备原材料订单、生产线上的VAA/NVAA活动、在制品(WIP)、工艺布局和出货计划时,管理层应考虑总CT/LT和风险的时间值(最小、最有可能(平均)、最大)。然而,本文的重点将放在使用开发的V-VSM和RA-FMEA模型的@ Risk软件进行蒙特卡罗模拟的验证上。将所得结果与传统VSM的结果进行了比较。

This project aims to establish the usage of Management and Science University’s on starting to deploy smart campus technologies on "Find 4 Me Application" where this application is essentially all about finding the user needs on indoor location guidance as well as the other specials features that are useful for the lives of new students and visitors while visiting the campus. New students and the visitors will always face the struggle to find the classrooms and the ability to get to know the resources in the campus environment. The main the reason why this problem occur was due to the area of the campus was bigger and not having a proper tool such as such as an indoor navigation system to make the student’s life easier to carry out their daily lives in the campus peacefully. This study aims to provide an user friendly application for new students and visitors on finding direction and guide to the specific places located indoor the Management & Science University which will help to create a more personalized campus experience for both students and visitors. Other than that, this application is also will provide other features such as the users will be able to explore 360 views of direction, book venues in MSU, able to use live chat feature and able to give feedback for the future purpose. The Spiral model is being used as the appropriate research technique and is being implemented as a guideline during this study to fulfil the project's goals. According to the findings, the system is reliable and trustworthy since the outcome corresponded to what was expected as it provides a personalizes student and visitors experience and engages in visual interaction.
本项目旨在建立管理与科学大学在“Find 4 Me应用程序”上开始部署智能校园技术的使用情况,该应用程序基本上都是关于在室内位置指导上找到用户需求以及其他特殊功能,这些功能对新生和访问校园的访客的生活有用。新生和访客总是面临着寻找教室和了解校园环境资源的困难。这个问题发生的主要原因是由于校园的面积更大,没有一个合适的工具,如室内导航系统,使学生的生活更容易在校园和平地进行日常生活。本研究旨在为新学生和访客提供一个用户友好的应用程序,帮助他们找到位于管理与科学大学室内特定位置的方向和指南,从而为学生和访客创造更个性化的校园体验。除此之外,该应用程序还将提供其他功能,例如用户将能够探索360度的方向视图,预订MSU的场地,能够使用实时聊天功能,并能够为将来的目的提供反馈。螺旋模型被用作适当的研究技术,并在本研究期间作为指导方针实施,以实现项目的目标。根据调查结果,该系统是可靠和值得信赖的,因为结果符合预期,因为它提供了个性化的学生和游客体验,并参与视觉互动。

Digital image watermarking is a tried-and-true method of securing image media, but there is a need to constantly perfect the technique to keep up with the technological progress. In this paper, a non-blind image watermarking technique is used to embed a robust and imperceptible watermark, designed with a focus on security and efficiency. Images are transformed from spatial domain to transform domain using modified non-separable Haar wavelet transform and singular value decomposition, and the watermark is encrypted by Arnold’s cat map scrambling and Rabin-p cryptosystem. The modified non-separable Haar wavelet transform is an alternative to the popular and widely used discrete wavelet transform, which produces a similar transform but in a much more efficient way. On the other hand, the watermark is secured by image scrambling and encryption of the scrambling parameters. A highly robust and imperceptible image watermarking technique is made while prioritizing efficiency and security.
数字图像水印是一种可靠的图像介质安全保护方法,但随着技术的进步,需要不断完善该技术。本文采用非盲图像水印技术嵌入鲁棒且不易察觉的水印,设计时注重安全性和高效性。采用改进的不可分Haar小波变换和奇异值分解将图像从空间域变换到变换域,采用Arnold猫图置乱和Rabin-p密码对水印进行加密。改进的不可分离Haar小波变换是目前广泛使用的离散小波变换的一种替代方法,它可以产生类似的变换,但效率更高。另一方面,通过图像置乱和置乱参数的加密来保证水印的安全。在兼顾效率和安全性的前提下,提出了一种鲁棒性强、不易察觉的图像水印技术。

Modern IT systems rely heavily on event logging and event logs. Many applications, operating systems, network devices, and other system components can log events to a local or remote log server. The existing log-based event analysis tools has limited forensic functionality, and search engines cannot filter the events by criteria. As a solution, this study provides a log analysis system that allows forensic investigators to log in using their email address and upload log files from an external device for processing. This also makes it possible to start a thorough investigation or carry out a quick analysis.

The paper focused on investigating the impact of factors that are believed to have a great effect on e- banking user acceptance in Jumhouria Bank, one of the biggest banks in Libya. The research will try to find out the reasons behind the reluctance of e-banking usage among customers in ten branches of Jumhouria banks in different four cities. The previous studies made in studying the factors affecting e-banking user acceptance in Libyan banks in general are considered low, the researcher focused on results of these few studied made on Libyan banks in addition of other studies made in other countries to try to identify and extract the important factors affecting banking in general. The findings of study will be used in the future to benefit both the bank and the customers. These findings shows that there is a significant relationship between the study independent variables which are: Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Perceived Information Technology Beliefs (PITB), Task Technology Fit (TTF), Website Features (WF) and Website Security (WS) on the dependent variable E-Banking User Acceptance (EUA) by using Intention to Use the technology (IU) as a Mediator variable. These findings shows that five hypotheses were supported and variables achieved P- value between 0.000 to 0.005 and one hypothesis was not supported.
本文重点研究了利比亚最大的银行之一Jumhouria银行的影响因素,这些因素被认为对电子银行用户接受度有很大影响。本研究将试图找出Jumhouria银行在四个不同城市的十个分行客户不愿使用电子银行的原因。以往对利比亚银行用户接受电子银行的影响因素的研究普遍被认为较少,本研究除了对其他国家的研究外,还对利比亚银行的少数研究结果进行了关注,试图识别并提取影响银行业总体发展的重要因素。研究结果将用于未来的银行和客户都受益。这些发现表明,本研究的自变量感知有用性(PU)、感知易用性(PEOU)、感知信息技术信念(PITB)、任务技术适配性(TTF)、网站功能(WF)和网站安全性(WS)对因变量电子银行用户接受度(EUA)存在显著的关系,并以使用技术意图(IU)作为中介变量。结果表明,5个假设得到支持,变量P值在0.000 ~ 0.005之间,1个假设不被支持。

The suspension system in an automotive vehicle is the interface between the vehicle body to the chassis and the road through the wheels. The main purpose of suspension is to absorb shock and vibration when the vehicle overcoming road irregularities. However, there are still issues where passive suspension is still unable to absorb maximum shocks in large vehicles for a pleasant ride when riding on an irregular road surface. This condition can cause a major risk to the driver which will cause the vehicle to experience rollover as the road bumps can cause instability to the vehicle. Therefore, the goal of this study is to determine the optimum spring constant, damping, toe angle and camber angle of the vehicle which allows them to optimally absorb the vibration due to road irregularities. The Trucksim software is used in this study to analyze the vehicle’s vertical acceleration mainly at different spring constants, damping, toe and camber angle of the truck. Methodology used in optimization of suspension system of the 3-axle semi-trailer truck subjected to road excitation is by using Taguchi method. Using Root Mean Square (RMS) measurements of vertical acceleration, the effect of suspension stiffness and suspension damping alongside with the toe and camber factor of the vehicle on vertical acceleration is investigated. The data produced from this study can be used by researchers to improve the driving behaviors and driving characteristics of heavy vehicles.
汽车的悬架系统是通过车轮将车身与底盘和道路连接起来的接口。悬架的主要作用是吸收车辆在克服路面不平时的冲击和振动。然而,被动悬架仍然存在一些问题,即在大型车辆上行驶时,在不规则路面上行驶时,仍然无法吸收最大的冲击。这种情况会给司机带来很大的风险,这会导致车辆侧翻,因为道路颠簸会导致车辆不稳定。因此,本研究的目标是确定车辆的最佳弹簧常数,阻尼,脚趾角和弧度角,使它们能够最佳地吸收由于道路不平引起的振动。本研究采用Trucksim软件,主要分析了不同弹簧常数、阻尼、车趾和车倾角下车辆的垂直加速度。采用田口法对道路激励下的三轴半挂车悬架系统进行优化。利用垂直加速度的均方根(RMS)测量结果,研究了悬架刚度和悬架阻尼以及车辆的趾部和弯曲系数对垂直加速度的影响。本研究产生的数据可用于研究人员改善重型车辆的驾驶行为和驾驶特性。

This study introduces a robot medical assistant that uses the Internet of Things to keep tabs on patients. That contributed to the development of a virtual doctor robot that would allow a doctor to freely move about an unfamiliar location and interact with patients and residents there. In addition, we look at some past studies that paved the way for the creation of similar systems. The important role that robotic technology has played in improving medical treatment and limiting the spread of disease. The ideal application for these robots is to limit patient-doctor interaction and provide backup in hospitals. This will help ensure that only those with a legitimate need to be at the hospital or quarantine facility at any given time are exposed to the disease. A Raspberry Pi and a smartphone app are used in parallel to create the robot. This camera-equipped QR-scanning robot is deployed in an isolated location, where its Raspberry Pi camera can take clear, high-resolution images that are then sent to a nearby screen and operated via a smartphone app. The findings from the preliminary tests reveal that data transmission and reception are stable, and the battery drain is shown to be a limitation.
本研究介绍了一种机器人医疗助手,它使用物联网来密切关注患者。这促成了一种虚拟医生机器人的开发,这种机器人可以让医生在不熟悉的地方自由移动,并与那里的病人和居民互动。此外,我们还回顾了一些为创建类似系统铺平道路的过去的研究。机器人技术在改善医疗和限制疾病传播方面发挥的重要作用。这些机器人的理想应用是限制医患互动,并在医院提供备份。这将有助于确保在任何特定时间只有那些有正当需要在医院或隔离设施的人才会接触到这种疾病。树莓派和智能手机应用程序并行创建机器人。这个配备摄像头的qr扫描机器人被部署在一个孤立的地方,它的树莓派摄像头可以拍摄清晰、高分辨率的图像,然后发送到附近的屏幕上,并通过智能手机应用程序进行操作。初步测试的结果显示,数据传输和接收稳定,电池消耗被证明是一个限制。
