This paper presents the conceptual design, analysis and manufacturing of a novel electrically-assisted human powered vehicle (HPV). The various stages in the conceptual development are discussed. The innovation that is introduced consists of an adjustable swing arm which enables configuration of the frame into either a reverse-trike or a conventional bike setup. Static analysis of the mainframe was performed prior to build, to ensure that the structure is safe and mechanically sound. The vehicle was successfully built, assembled, and tested.

We present a novel detector for measuring the charge and mass of micron-sized particles. Detection of charge is based on charge induction on electrodes connected to a custom differential amplifier. Mass is calculated from particle acceleration in an electric field. A custom software program processes the amplifier signals and produces charge and mass calculations, along with calculation uncertainties based on the experimental errors. Using our detector and software, we evaluated charge and mass for clumps of 5 μm silicon dioxide particles. Our detector can potentially be used in interplanetary research missions studying particle size and charge distributions.

When wind turbine blade faults are not detected at an early stage, they can become costly to fix as the damage could worsen over time and the maintenance costs of the blades could increase. This paper investigates a monitoring method for efficient and accurate damage detection and fault diagnosis of wind turbine blades by using pictures of the blades. The method uses a Residual Neural Network, a model of Convolutional Neural Networks, with an integration of wavelet-based layers. This approach aims to improve the health monitoring system of the wind turbine blades and the accuracy of fault detection to reduce the monitoring cost and the operation interruptions of the wind turbines due to severe damage to the blades.

This case study shows the initial results of aiming for reducing the cost, man-hours, and safety risks involved with the external structural inspection process of wind turbines using a fully automated drone-based system. The end goal is to use object detection and path planning algorithms to automate the process of identifying a specific wind turbine in the field via a drone, safely approaching the wind turbine, and capturing the images necessary for analysis and inspection. Our case study here serves as a small-scale proof of concept for the path planning solutions using pedestal fans in the place of wind turbines and a Tello EDU drone. Our study demonstrates the success of the drone to autonomously explore the region of interest, detect the desired fan, safely approach the fan, verify the fan via scanning the associated QR code, capture video and images from multiple angles, and safely fly back to the starting point and land.

The objective of this research was to evaluate the viability of replacing sand with waste polypropylene plastic in standard cement-lime mortar typical of that used for concrete masonry wall construction. The results of this research indicate that, because of the rough surface texture of the plastic particles that resulted from grinding, the amount of water required to achieve a given mortar flow increased as the percentage of plastic increased. As the amount of water increased, corresponding to higher water-cementitious materials ratios, the compressive strength decreased. To compensate for these effects, higher concentrations of cement and comparatively lower concentrations of sand and plastic were required to meet compressive strength specifications. For a baseline mixture design similar to that used for batch 3 in this research, up to 10 percent of the sand by volume can be replaced with plastic. This mixture design not only exceeded the minimum strength required for a Type N mortar, but it also exhibited levels of durability comparable to those of mortar mixtures not comprising plastic in terms of exposures to a freeze-thaw cycle and to fire. Furthermore, the incorporation of plastic decreased the density of the mortar, which may be beneficial in many applications.

A far-infrared filter is fabricated by creating metallic squares on a dielectric substrate. This capacitive metallic filter is fabricated using direct write laser ablation consisting of a femtosecond laser in combination with a high numerical aperture objective. A representative capacitive filter is fabricated on sodalime glass substrate with a period of 100 μm and separation width of 30 μm. A partial capacitive filter was also fabricated on a thin film polyethylene substrate with similar dimensions.

The digital twin adds a great value to the interlinking of work steps in control cabinet construction. The model is created in electrical design and during assembly planning. The twin then accompanies the entire production process and provides the individual departments with their information. The unique feature: customer, switchgear manufacturers, and their suppliers work with the same model. The device manufacturers supply macros in which all the properties of their products are mapped. The electrical designers insert these devices into their schematic and thus generate a logical version of the model. The layout planner then puts the model into physical form by arranging the devices in the virtual switchgear cabinet. The finished model includes all dimensions and shows the individual devices inside the realistic 3D digital layout. Also included is the entire wiring with all wire paths, cable ducts, top-hat rails (position and length), and all drill holes and cutouts. The haptic representation simplifies many activities, as individual positions in the cabinet are more easily recognized. As a result, production is less time-consuming, and the susceptibility to errors is significantly reduced. Such a solution is presented using the EPLAN platform and the products Data Portal, Electric P8, Pro Panel, including the connection of the software to the actual machines, which have the task of creating a real construction out of the simulation of a digital twin.
数字孪生对控制柜施工中各工序的互联互通具有重要的价值。该模型是在电气设计和装配规划期间创建的。然后,孪生兄弟陪同整个生产过程,并向各个部门提供他们的信息。独特的特点:客户、开关柜制造商及其供应商使用相同的型号。设备制造商提供宏,其中映射了其产品的所有属性。电气设计人员将这些器件插入到他们的原理图中,从而生成模型的逻辑版本。然后,布局规划者将虚拟开关柜中的设备布置成物理形式。完成的模型包括所有维度,并在现实的3D数字布局中显示单个设备。还包括整个布线与所有的电线路径,电缆管道,顶帽导轨(位置和长度),以及所有的钻孔和切割。触觉表现简化了许多活动,因为橱柜中的个人位置更容易识别。因此,生产时间更短,对错误的敏感性也大大降低。使用EPLAN平台和产品Data Portal, Electric P8, Pro Panel提出了这样的解决方案,包括将软件连接到实际机器,这些机器的任务是创建一个真实的数字双胞胎模拟的结构。

Appropriate drainage system is a key factor in any roadway design project. Inadequate drainage infrastructure can cause premature deterioration of the highway as well as the development of hazardous safety circumstances such as hydroplaning. Qatar, a developing country in the Middle East, built a new drainage system in the city of Doha. The new system functioned with acceptable design efficiency and managed to mitigate the flooding problems after the end of rainfall. This study aims to compile the challenges and key lessons learned from building the new system. The results of this study can help engineers, planners, and public agencies plan, study, and design similar facilities.

The 21st-century healthcare information systems (HCIS) acquire, integrate, analyse, and explore heterogeneous data available in several information sources to benefit multiple stakeholders. However, current research has mostly focused on technological aspects instead of being concerned with underlying concepts that could be reused to develop HCIS. Here, we sketch a reference architecture following primary requirements that future HCIS should consider. We describe and associate these requirements to each architectural element and demonstrate how the architecture can guide the development of a medical question-answering system. The main contribution is the reuse of common functionalities of the current generation of HCIS.
