Abstract Highway users can apprehension to certain subjects with utilizing of Vehicular Ad-hoc Networks (VANET) applications if the rules for safe overtaking movement are violated to make the lane change maneuver between vehicles on the highway road. In our research, we suggest an algorithm for semi-automated vehicles S-AV compliant lane change to emphasize rules for safe overtaking between vehicles on the highway. The proposed algorithm technique classify the safe overtaking into major categories and critically analyzed them depending on various classes of lane change movements between vehicles interrelated to road condition based on different performance criteria; this technique will add awareness to drivers traveling on highway to increasing the comfort and safety of driving. Finally, we have conclude and suggest research issues associated to Vehicular Ad-hoc Networks to investigate and ensure the real-time decision of safe overtaking between vehicles on the highway, which is important research task to motivate researchers to connect the semi-automated vehicles with driver face emotion detection and increase driving safety.

Abstract Conducting a safe briefing is essential to educate aircraft maintenance personnel, who very often encounter various unexpected and dangerous incidents. Their reaction to situations should be quick and adequate. To train aircraft maintenance professionals who cannot be practiced in real life due to high cost, danger, time or effort, virtual training seems like an obvious choice. This paper is devoted to the development of a calculation algorithm for assessing the risk of actions taken at the aircraft repair site, which was implemented in the training version of the virtual reality (VR) simulation. It includes a number of factors and elements that form the simulation scenario, influencing the degree of its complexity and the assessment of the performance of each exercise. Various components of the algorithm are presented, which allow assessing the skills of students of aviation specialist courses. The criterion for the acceptability of the developed algorithm is the correct assessment of the student’s skills in the course of training.
摘要飞机维修人员经常会遇到各种意想不到的危险事件,对他们进行安全培训是必不可少的。他们对情况的反应应该迅速而充分。由于成本高、危险、时间或精力等原因,无法在现实生活中训练飞机维修专业人员,虚拟培训似乎是一个显而易见的选择。本文致力于开发一种用于评估飞机维修现场行动风险的计算算法,并在虚拟现实(VR)仿真的训练版本中实现。它包括形成模拟情景的许多因素和要素,影响其复杂程度和对每个演习性能的评估。提出了该算法的各个组成部分,用于评估航空专业课程学生的技能。所开发算法的可接受性的标准是在训练过程中对学生技能的正确评估。

Abstract The aim of this article is to assess the carbon dioxide (CO2) emissions of three types of cars: two internal combustion cars and one Fuel Cell Electric Vehicle (FCEV), measured on the basis of type approval regulations. The article also assesses the CO2 emission costs resulting from the production of fuel and the production of the car. It was assumed as a research hypothesis that the development and growing serial production of vehicles with different power systems will bring measurable changes in CO2 emissions from road transport. Based on their own research, the authors also analyzed the credibility of the assumptions made about the benefits related to emissions resulting from replacing the classic vehicle with hydrogen one. They estimated the duration and intensity of use of a hydrogen vehicle that offers CO2 benefits compared to a conventional vehicle.

Abstract The methodology of graph theory has long had applications in mechanics. Graphs allow the simultaneous consideration and synthesis of the structure of a real system and the idealized structure of an equivalent model of a mechanical system. In particular, there are many applications of graph theory in the analysis of automatic transmissions. This paper presents continuing research on applications of game tree graphs in the analysis of automatic transmissions. Black box ideas for dependency graphs are presented. This makes it possible to automatically generate simplified models from given physical models of an automatic transmission and to determine the optimal number of teeth. The developed methodology allows also to perform real-time simulations. In a further stage, the methods of decision logic trees can be applied to analyze the functional diagrams of selected gears.

Novel Method of Reducing the Allocated Bandwidth by Voip 一种减少Voip分配带宽的新方法

Abstract Old telecommunication systems are gradually being replaced by a new system that works over IP networks, which is known as voice over internet protocol (VoIP). VoIP has several merits (e.g., very cheap call rate), which make it increasingly popular in the telecommunication world. However, VoIP faces numerous impediments that decelerate its promotion. One of the top impediments is the wasted bandwidth caused by VoIP systems. Numerous methods have been proposed to handle this impediment, including packet aggregation methods. This paper proposes a novel aggregation method, called packet aggregation and carrier header (PA-CH), to reduce the amount of the large bandwidth caused by VoIP. As the name suggests, PA-CH saves in bandwidth by aggregating the packets in a header and using the redundant fields in the packet header to carry a portion of the packet voice data. The performance of the introduced PA-CH method was investigated based on three main metrics, namely, link capacity, allocated bandwidth reduction, and voice data shortening. Simulation results indicate that the proposed PA-CH method outperforms the comparison methods in three factors. For instance, the proposed method’s allocated bandwidth reduction ratio reaches 51% when the number of calls running concurrently reaches 100. Therefore, the proposed PA-CH method achieves its goal of reducing the wasted bandwidth caused by VoIP.
旧的电信系统正逐渐被一种基于IP网络的新系统所取代,这种新系统被称为互联网语音协议(VoIP)。VoIP有几个优点(例如,非常便宜的话费),这使得它在电信界越来越受欢迎。然而,VoIP面临着许多阻碍其推广的障碍。最大的障碍之一是VoIP系统造成的带宽浪费。已经提出了许多方法来处理这种障碍,包括分组聚合方法。本文提出了一种新的聚合方法——分组聚合和载波头聚合(PA-CH),以减少VoIP带来的大带宽量。顾名思义,PA-CH通过在报头中聚合数据包并使用报头中的冗余字段来携带部分数据包语音数据来节省带宽。基于链路容量、分配带宽减少和语音数据缩短三个主要指标对所引入的PA-CH方法的性能进行了研究。仿真结果表明,所提出的PA-CH方法在三个方面都优于比较方法。例如,当并发运行的呼叫数达到100时,所提方法的分配带宽减少率达到51%。因此,本文提出的PA-CH方法达到了减少VoIP带来的带宽浪费的目的。

Abstract The carsharing services have become the necessary component of the life of smart and sustainable city. They meet the numerous requirements put forward by these cities concepts and make life in urban environment cleaner, more comfortable and convenient and better organized. The goal of this research is to determine the factors facilitating the demand for the carsharing services, and on the basis of this analysis to consider the costs structure of these companies. The results are obtained via PLS-SEM analyses implementation in SmartPLS-3.3.7 software. The analysis revealed that such factors as Convenience, Additional Values and Economic (saving factors) have positive impact on growth of demand for carsharing services while New Way of Thinking is insignificant. However, the developed Costs function demonstrate that companies assume the costs of promoting “green” effect of carsharing as important ones. If they reduce these types of costs, it will have positive impact on their efficiency without decrease of demand.
汽车共享服务已经成为智慧可持续城市生活的必要组成部分。它们满足了这些城市理念提出的众多要求,使城市环境中的生活更干净、更舒适、更方便、更有条理。本研究的目的是确定促进汽车共享服务需求的因素,并在此分析的基础上考虑这些公司的成本结构。结果通过在SmartPLS-3.3.7软件中实现PLS-SEM分析获得。分析发现,便利性、附加价值和经济性(储蓄因素)等因素对汽车共享服务需求增长有正向影响,而新思维方式对汽车共享服务需求增长的影响不显著。然而,开发的成本函数表明,企业将促进共享汽车“绿色”效应的成本视为重要成本。如果他们降低这些类型的成本,这将对他们的效率产生积极的影响,而不会减少需求。

Abstract Railway traffic safety is a decisive factor involved in any decision-making process in the railway transport, including the overall weight of cars, i.e., potential overloading. Overloaded rolling stock may cause many serious accidents. The presented article comprises two parts: the theoretical one explores the ways of progressive dynamic weighing of shipment. The practical part took place at Horní Dvořiště railway station, measuring the impact of the dynamic weighing on the decline in vehicular overloading.
铁路交通安全是铁路运输决策过程中涉及的决定性因素,包括车辆总重量,即潜在的超载。铁路车辆超载可能造成许多严重事故。本文包括两个部分:理论部分探讨了货物累进动态称重的方法。实践部分在Horní Dvořiště火车站进行,测量动态称重对车辆超载下降的影响。
