Usually buildings consume large amount of electricity for heating and cooling purposes, which can reach higher than 40%. Heat pumps are highly efficient devices that are used to lower energy consumption because they just require a little amount of electric power to trans-fer heat from a lower to a higher temperature source, which is the opposite of the natural flow. Green-house gas emissions can be reduced consequently if the electric power input is supplied from renewable energy sources such as hydropower, geothermal or solar energy. These devices can provide two to six times more energy output from the input energy required for system operation. Thermodynamic analysis is done for heating and cooling cycles of the heat pumps. Moreover, the different types and configurations will be discussed in addition to its various applications in real life. At the end, it is a useful device that can be used to lower energy consumption and emissions.
通常建筑物用于供暖和制冷的耗电量很大,可达40%以上。热泵是一种高效的设备,用于降低能源消耗,因为它们只需要少量的电力将热量从较低的温度源传递到较高的温度源,这与自然流动相反。因此,如果输入的电力来自水电、地热或太阳能等可再生能源,则可以减少温室气体排放。这些设备可以提供比系统运行所需的输入能量多两到六倍的能量输出。对热泵的加热和冷却循环进行了热力学分析。此外,除了在现实生活中的各种应用之外,还将讨论不同的类型和配置。最后,它是一个有用的装置,可以用来降低能源消耗和排放。

The current standard procedure for firearm examination is to compare two gunshot samples, one from the crime scene and the other from a firearm test shot. A bullet recovered at a crime scene can be studied using a comparison microscope, which allows a ballistics examiner to determine and compare the bullet to ascertain its source and if it was shot from the same firearm, which is a subjective analysis. The purpose of this research is to evaluate the approach of artificial intelligence for the examination of bullets to obtain an objective analysis. An effort was made through this research to evaluate the aims of artificial intelligence in forensic ballistics and to examine the class characteristics such as rifling marks and individual characteristics of a bullet and include a method of recommendation. The end-point objectives of this review are improvements and alterations to enhance the examination of a submitted bullet using the latest technological innovation such as a virtual microscope, quantum 3D microscope, and artificial intelligence expert systems. In conclusion, we discussed the use and relevance of advanced technologies to help obtain a reliable assessment of the bullet comparison other than the conventional methods.
目前枪支检查的标准程序是比较两个枪击样本,一个来自犯罪现场,另一个来自枪支测试射击。在犯罪现场发现的子弹可以使用比较显微镜进行研究,这使得弹道学检查员可以确定和比较子弹,以确定其来源,以及是否来自同一支枪,这是一种主观分析。本研究的目的是评估人工智能对子弹检测的方法,以获得客观的分析。通过这项研究,我们努力评估人工智能在法医弹道学中的目的,并检查子弹的类别特征,如膛线痕迹和个体特征,并包括一种推荐方法。本综述的最终目标是使用最新的技术创新,如虚拟显微镜、量子3D显微镜和人工智能专家系统,改进和改变以加强对提交子弹的检查。总之,我们讨论了先进技术的使用和相关性,以帮助获得可靠的评估,而不是传统方法的子弹比较。

The COVID-19 pandemic has imposed rapid and significant changes upon education systems. Most educational institutions transferred abruptly from traditional face-to-face delivery to distance learning formats through virtual classrooms. As a result of this shift, many faculty members have faced challenges in keeping their students engaged during lectures. Gamification is often proposed as a promising solution to enhance student motivation, engagement, and learning outcomes attainment. This study investigates the effectiveness of the gamification mechanism on undergraduate students in a computer programming course using Kahoot! and Nearpod during distance learning. The findings of the study show that there is some correlation between student engagement, learning motivation, academic performance, and the use of gamification.

A severity analysis is made to evaluate the effect of corresponding shock or transient vibration on the man on the vehicle passing through a series of road bumps. Road bumps cause undesirable human vibrations due to vehicle vibration meant to limit the vehicle speed. In this study, vehicle vibrations are first computed following the vibration analysis procedure, in which equations of motion are solved using MATLAB. A light vehicle is employed to record vibration measurement using a triaxial accelerometer setup indigenously with data acquisition using a laptop. The total vibration level received at the vehicle is evaluated through the design of the Vibration Nomograph based on ISO 2631 to assess the harmful and/or dangerous levels of vibration. It is found that if human beings are exposed to this level vibration for a more extended period of 12-h or more, they will be facing health hazards such as effects on the central nervous system and musculoskeletal diseases.
对车辆通过一系列道路颠簸时,相应的冲击或瞬态振动对人的影响进行了严重程度分析。由于车辆的振动,道路颠簸会导致不希望的人体振动,这意味着限制车辆的速度。在本研究中,首先根据振动分析程序计算车辆振动,并利用MATLAB求解运动方程。使用轻型车辆记录振动测量,使用本地设置的三轴加速度计,使用笔记本电脑进行数据采集。通过基于ISO 2631的振动Nomograph设计来评估车辆接收的总振动水平,以评估有害和/或危险的振动水平。研究发现,如果人类暴露在这种水平的振动中12小时或更长时间,他们将面临诸如中枢神经系统和肌肉骨骼疾病的影响等健康危害。

However, various systems have been utilized for each application. In this research, we present a fault detection approach based on computer vision and deep learning that can be used for a variety of applications. We tested our model on three distinct datasets of different engineering problems. A MobileNetV2 based convolutional neural network model was applied on different engineering problems related photovoltaic solar, manufacture of magnetic tiles and electrical commuter systems. The results obtained for these three cases are: 85 percent, 92 percent, and 92 percent, respectively.

Floors safety is the primary concern globally due to the injuries and fatalities caused by slippery flooring surfaces. Flooring surfaces with wear and tear developments may have poor frictional properties that can negatively affect the slip resistance performance and provide unsafe environments to pedestrians by causing slip, trip, and fall incidents. This study reviews the current technological advancements in the literature associated with two main keywords of floor safety and traction properties to assess and predict flooring slipperiness in terms of coefficient of friction (COF). This study enhances the existing literature by providing recommendations for the future research direction in assessing shoe-floor slip resistance performance using structural analysis tools.
由于地板表面湿滑造成的伤害和死亡,地板安全是全球主要关注的问题。具有磨损和撕裂发展的地板表面可能具有较差的摩擦性能,这可能会对防滑性能产生负面影响,并通过引起滑倒,绊倒和跌倒事件为行人提供不安全的环境。本研究回顾了目前与地板安全性和牵引性能两个主要关键词相关的文献中的技术进展,以摩擦系数(COF)来评估和预测地板的滑动性。本研究在现有文献的基础上,对未来使用结构分析工具评估鞋-地抗滑性能的研究方向提出了建议。

The rapid advances in technology over the last decade have significantly altered the nature of engineering knowledge and skills required in the modern industries. In response to the changing professional requirements, engineering institutions have updated their curriculum and pedagogical practices. However, most of the changes in the curriculum have been focused on the core engineering courses without much consideration for the auxiliary courses in mathematics and sciences. In this paper, we aim to propose a new, augmented mathematics curriculum aimed at meeting the requirements of the modern, technology-based engineering workplace. The proposed updates require minimal resources and can be seamlessly integrated into the existing curriculum.
在过去的十年中,技术的快速进步已经显著地改变了现代工业所需的工程知识和技能的性质。为了应对不断变化的专业要求,工程院校已经更新了他们的课程和教学实践。然而,课程的变化大多集中在核心的工程课程上,而没有考虑到辅助的数学和科学课程。在本文中,我们旨在提出一种新的,增强数学课程,旨在满足现代,技术型工程工作场所的要求。拟议的更新只需要最少的资源,并且可以无缝地整合到现有的课程中。

Effects of heat-loss on the effectiveness of a multi-fluid heat exchanger are analyzed in the current work. The tri channel heat exchanger with three communicating fluids is discretized and evaluated using the finite element method. Dimensionless parameters are defined and used to enhance the adaptability of the method, and to study the effects of energy loss to surroundings in the form of heat on the heat exchanger’s operating fluid behavior. The detailed parametric analysis carried out in the work quantifies the performance degradation of the tri-fluid recirculating type heat exchanger due to energy loss to surroundings.

Stress concentrations induced by geometric discontinuities can have detrimental effects on the structural reliability and integrity of components subjected to static or cyclic loadings. Thus, it is instrumental to have the knowledge to predict the stress concentration levels induced by a wide range of geometric discontinuities that cannot be avoided in engineering applications. This work aims to shed light into the cooperative interactive stress concentrating effects of coexisting geometric discontinuities. In particular, this work computationally investigates the stress concentration induced by the interaction of closely placed through-holes and fillets. Results show that the stress concentration induced by the cooperative interaction of the investigated geometric discontinuities far exceeds the stress concentration induced independently by each of them.
几何不连续引起的应力集中会对静力或循环荷载作用下构件的结构可靠性和完整性产生不利影响。因此,掌握预测由工程应用中无法避免的大范围几何不连续引起的应力集中水平的知识是有用的。本研究旨在揭示共存几何不连续的协同交互应力集中效应。特别地,这项工作计算研究了由紧密放置的通孔和圆角相互作用引起的应力集中。结果表明,由几何不连续面协同作用引起的应力集中远大于各几何不连续面单独引起的应力集中。

In this study a third-order electrical analogue of the cardiovascular system (CVS) is presented, where pressures, volumes and flows are represented by voltages, charges and currents, respectively. The left atrium and the elastic arteries and veins are modeled as capacitive elements (reservoirs) with constant compliance (C) while the left ventricle is modeled as a capacitive element with variable elastance (e = 1/C), and vascular resistances are modeled as resistive (R) elements. The circuit is simplified by lumping together systemic arteries, arterioles and capillaries in the aortic; systemic veins and capillaries, right atrium and ventricle, and pulmonary arteries in the venous; and pulmonary capillaries and veins into the left atrial compartments. The state variables are chosen as the pressures of the left atrium, left ventricle and aorta. Although the model does not include major physiological feedback mechanisms such as neuro-hormonal pathways or the coronary arterial system, cardiac hemodynamics are simulated with high accuracy. This model is intended to be taken as the template for a bench-top physical platform to test the pre-clinical performance of novel Left Ventricular Assist Devices placed parallel to the LV and AO in future studies.
在这项研究中,提出了心血管系统(CVS)的三阶电模拟,其中压力,体积和流量分别由电压,电荷和电流表示。左心房和弹性动脉和静脉被建模为具有恒定顺应性(C)的电容元件(储层),而左心室被建模为具有可变弹性(e = 1/C)的电容元件,血管阻力被建模为电阻(R)元件。该回路通过将全身动脉、小动脉和主动脉毛细血管集中在一起而得到简化;全身静脉和毛细血管,右心房和右心室,静脉中的肺动脉;肺动脉毛细血管和静脉进入左房室。状态变量选择为左心房、左心室和主动脉的压力。虽然该模型不包括主要的生理反馈机制,如神经激素通路或冠状动脉系统,但心脏血流动力学的模拟精度很高。本模型拟作为一个台式物理平台的模板,在未来的研究中测试与左室和左室平行放置的新型左室辅助装置的临床前性能。
