Indian Railways being one of the largest functioning units of India employs a huge amount of manual unorganized labor. Maintenance of railway coaches and bogies is provided from part of this labor. It has always been a great challenge to find an optimal operating scenario for maximized productivity. In this work, we aimed to model and maximize maintenance productivity of Indian Railway coach and bogie . Taking into consideration the volatility of the circumstances and uncorrelated behavior of different human factors affecting productivity, to obtain the best scenario five of the most critical human factors were identified that are expected to affect the maintenance of the coaches and bogies most. Cobb-Douglas production function was used to model maintenance productivity with the chosen human factors. The main goal after designing the model for productivity is to maximize it. To get the optimal productivity Differential Evolution algorithm is used. Finally, the Cuckoo search algorithm is applied to validate the results.
印度铁路是印度最大的运作单位之一,雇佣了大量的无组织劳动力。铁路车厢和转向架的维护是由部分劳动力提供的。找到一个最佳的操作方案来最大化生产效率一直是一个巨大的挑战。在这项工作中,我们旨在模拟和最大化印度铁路客车和转向架的维修效率。考虑到环境的波动性和影响生产力的不同人为因素的不相关行为,为了获得最佳方案,确定了五个最关键的人为因素,这些因素预计会影响教练和转向架的维护。采用柯布-道格拉斯生产函数对所选人为因素的维修生产率进行建模。设计生产力模型后的主要目标是使其最大化。为了获得最优生产率,采用了差分进化算法。最后,应用布谷鸟搜索算法对结果进行验证。

Economic indexes can be influenced by many different factors; therefore, it is difficult to use a single variable linear regression to determine the effectiveness of patterns. Modeling an economic pattern for a focused area and performing data analysis is especially difficult with a complex data pattern. To predict the effectiveness of such a trend, this paper focuses on a specific, objective main factor that determines the economic status in the field of stock markets. The CBOE Volatility Index, known by its ticker symbol VIX, is a popular measure of the stock market’s expectation of volatility implied by S&P 500 index options. It is calculated and disseminated on a real-time basis by the Chicago Board Options Exchange (CBOE) and is commonly referred to as the fear index, or the fear gauge. In this paper, a statistical method is used to model the distribution of the maximum/minimum of a number of samples. Statistical measurements such as exceedance probability that an event exceeds mean value and return period are found based on historical data.
经济指标受多种因素的影响;因此,很难使用单变量线性回归来确定模式的有效性。对于复杂的数据模式,为重点领域建模经济模式并执行数据分析尤其困难。为了预测这种趋势的有效性,本文着重研究了决定股票市场经济地位的一个具体的、客观的主要因素。芝加哥期权交易所波动率指数(CBOE Volatility Index)是衡量股市对标普500指数期权隐含波动率预期的常用指标。它是由芝加哥期权交易所(CBOE)实时计算和传播的,通常被称为恐惧指数或恐惧指标。本文采用统计方法对若干样本的最大值/最小值的分布进行建模。统计度量,例如事件超过平均值的概率和返回周期,是基于历史数据发现的。

The benefits of Autonomous Driving (AD) and Advanced Driver Assistance Systems (ADAS) include providing critical capabilities that would help to reduce accidents due to driver errors, improve safety in traffic, and enhance driving efficiency. The goal of this paper is to utilize the Robot Operating System (ROS) and Gazebo 3D simulator for realizing a fully immersive software-in-the-loop (SIL) simulation framework, which could be utilized for the virtual design, verification, and validation of AD/ADAS features. It supports designing and implementing a software platform and methodology to validate different features for AD/ADAS with a high degree of realism. The paper will also discuss the configuration of the sensors, such as the camera, LiDAR, and RADAR, that are later used as part of a sensor fusion technique that shows the usability of the developed environment.

This study has analyzed the mechanical processes that would lead to an optimal design of indexed milling tools that have WC inserts. This thesis deals with the finite element stress analysis at the rake face of milling inserts with three dimensional shape. It was idealized by simplifying cutting forces uniformly distributed loading and elastic behavior was assumed.. Simulation was run on tungsten carbide specimens. Firstly, the shape of the insert cutting edges under the varying angles of the inserts were suggested. Then, an observed cutting force model was made. This permits analyzing the outcomes of the finite element stress on the cutting forces. A time-sensitive analysis was also made to observe the dynamic cutting forces and utility for the milling process. Afterwards, the models were put in a computer program to make the protocols of the models. The results show that there is a local maximum tensile stress on the rake face of the insert. It is also shown that there exist high shear stresses near the insert edge and that the normal stress decreases exponentially from a maximum value at the loading tool edge to minimum value at the other side of the insert. Results obtained are similar to those of orthogonal cutting but very much dependent on the shapes of the insert.
本研究分析了机械过程,这将导致具有WC刀片的索引铣刀的优化设计。本文对具有三维形状的铣刀前刀面进行了有限元应力分析。通过简化切削力对其进行了理想化,并假设了均匀分布载荷和弹性特性。对碳化钨试样进行了仿真。首先,给出了刀片在不同角度下的切削刃形状;建立了切削力观测模型。这允许分析切削力上的有限元应力的结果。对铣削过程的动态切削力和效用进行了时间敏感分析。然后,将模型放入计算机程序中制作模型的协议。结果表明:刀片前表面存在局部最大拉应力;结果还表明,在刀片边缘附近存在较高的剪应力,而正应力从加载刀具边缘的最大值到刀片另一侧的最小值呈指数递减。得到的结果与正交切削相似,但很大程度上取决于刀片的形状。

Nowadays, the evolution of a factory has pushed towards a smart learning factory. By having the ability to learn, monitor each device and the resulting product will get more precise product results according to design. Detection of a place to put a product or called a jig on a shuttle whose number is different becomes something that is often missed from observation. With the scanning method with five pieces of ultrasonic sensors, the detection speed is 50 µs, and the detection accuracy is 100% for distances less than 25cm. The detection process of the jig is sent and stored by IoT Gateway as a Big Data Cluster via wifi media with a performance of 99.4%. The process of storing data on the IoT Cloud as the Main Big Data has a performance of 100% of the data on the IoT Gateway.

This paper presents further development and utilization of force platforms to evaluate and analysis of forces obtained due to rotation movements of sport activities using Labview software. The platform was designed with ring-shaped to provide and simulate the required space of rotation for testing these activities. The proposed force platform was fabricated with 2.5 m diameter and calibrated with standard force platforms to provide the required measurement sensitivity and accuracy. The data acquisition and Labview software were developed to perform different mathematical calculations. The obtained experimental tests results for different throwing sport activities showed good convergence to analyse athletes performances. Although the proposed force platform was initially employed to measure and analyse force due to rotation, it can be employed to measure other parameters related to athletes performances including torque, acceleration, displacement and moment based on computer vision tracking system. In comparison with the existing platforms, the fabricated platform has features of collecting a large variety of data with high quality for analysis and decision-making of athletes performances performing rotation movements.

Increasing Autonomy of I/O Cores in Heterogeneous FPGA-SoCs for Data Acquisition Applications 数据采集应用中异构fpga - soc中I/O核自主性的提高

As the architectures of FPGA-SoCs become more complex, it is increasingly important to find new ways to optimize the utilization of the interconnects that connect the various components like I/O cores, processors, and memories. Here we present a semi-autonomous soft I2C core and a systematic analysis of the performance characteristics of this core in a Linux system. Compared to a conventional I2C core, the devised core used with a new API reduces the average irq processor utilization in monitoring applications by 87.28% for SMBus Read Word operations and by 81.59% for SMBus Write Word operations, while maximizing I2C bus throughput and improving temporal predictability of I2C message transfers. The results show that overhead of interrupt processing to periodically fill a TX FIFO can be substantial and that designing an I/O core to be less dependent on a general-purpose processor can improve system performance considerably.
随着fpga - soc的体系结构变得越来越复杂,寻找新的方法来优化连接各种组件(如I/O内核、处理器和存储器)的互连利用率变得越来越重要。在这里,我们提出了一个半自治的软I2C内核,并系统地分析了该内核在Linux系统中的性能特征。与传统的I2C核心相比,使用新API的设计核心在SMBus Read Word操作和SMBus Write Word操作中降低了监控应用程序中的平均irq处理器利用率87.28%和81.59%,同时最大化了I2C总线吞吐量并提高了I2C消息传输的时间可预测性。结果表明,周期性地填充TX FIFO的中断处理开销可能是巨大的,并且设计一个对通用处理器依赖较少的I/O核心可以大大提高系统性能。

The National Center for Missing & Exploited Children estimated that 161 AMBER Alerts were issued in the U.S. involving 203 children in 2018, where 85% had involved vehicles and in Florida, 136 Silver Alerts were issued in 2008-2009. The details of broadcasting in Amber and Silver alerts are color, type of the vehicle, vehicle license plate numbers, and car brands. This paper is focused on classifying and detecting vehicle types, colors, and license plates. Currently, a child and older adult were rescued when someone recognized the vehicle in the alert. This paper proposes to design a Machine Learning model to classify the vehicle’s colors, types and recognize each vehicle’s license plate from camera feeds under different weather conditions and to find possible matches involved in these emergency alerts for the safe return of a child and older adult. Vehicle types include seven classes such as SUV, Sedan, Truck, Bus, Microbus, Minivan, and Motorcycle. Vehicle colors include eight classes: green, blue, black, white, gray, yellow, white, and red. When an Amber or Silver signal is broadcast, the proposed design checks with the vehicle’s specifications and extracts the color and type of the vehicle. The model then recognizes the vehicle’s license plate of specific vehicle’s color and type using image processing techniques and give notification of detected vehicle. Implementing CNN, real-time object detector YOLO, and character recognition model will improve detection and classify vehicle’s type, color, and recognize license plate numbers and letters accurately under different environmental conditions for Amber and Silver alert emergencies.
据美国国家失踪和受剥削儿童中心估计,2018年美国共发布了161个安珀警报,涉及203名儿童,其中85%涉及车辆,佛罗里达州在2008-2009年发布了136个银色警报。在琥珀色和银色警报中广播的细节是车辆的颜色、类型、车辆车牌号码和汽车品牌。本文的重点是分类和检测车辆类型,颜色和车牌。目前,当有人认出警报中的车辆时,一名儿童和一名老人获救。本文提出设计一个机器学习模型,对车辆的颜色、类型进行分类,并在不同天气条件下从摄像头提供的信息中识别每辆车的车牌,并在这些紧急警报中找到可能的匹配,以确保儿童和老年人的安全返回。车辆类型包括SUV、轿车、卡车、巴士、微型巴士、小型货车和摩托车等7类。车辆颜色包括绿、蓝、黑、白、灰、黄、白、红八种颜色。当广播琥珀色或银色信号时,建议的设计与车辆规格进行检查,并提取车辆的颜色和类型。然后利用图像处理技术识别出特定车辆的颜色和类型的车牌,并给出被检测车辆的通知。实现CNN、实时目标探测器YOLO和字符识别模型,提高对不同环境条件下车辆类型、颜色的检测和分类,并准确识别车牌号码和字母。
