The disconnection of the style of the urban scene from the historical axes: Al-Rasheed Street is a case study 城市景观风格与历史轴线的脱节:拉希德街是一个案例研究
Pub Date : 2023-08-25 DOI: 10.52113/3/eng/mjet/2023-11-02/36-46

The research investigates the urban scene as a witness to the city's memory and heritage and an expression of its cultural values. The urban scene, if sudden and unstudied visual images appear in it, and thus the emergence of different models between one axis and another, hence the research problem (disruption of the relationship between the constituent styles of the urban scene within the historical axes and the emergence of sudden visual images), Therefore, the research will aim to determine the reasons for the discontinuity in the visual sequence of the style and the emergence of sudden visual images of the urban scene. However, Baghdad, with its high cultural value, began to be interrupted as a result of interventions, which separated many parts of it from the urban style around it. The research will depend on the qualitative approach. The research concluded that Al-Rasheed Street suffers from a visual interruption in some parts of its urban scene as a result of social reasons related to individual or political transgressions related to the absence of penalties or economic ones related to the increase in the value of the land, in addition to the impact of the urban side that results in the removal or demolition of historic buildings. Furthermore, this led to a negative impact on the model of Al-Rasheed Street.
该研究调查了城市景观,作为城市记忆和遗产的见证,以及其文化价值的表达。城市风光,如果突然和优雅的视觉图像,从而出现不同模型之间的一个轴,另一个,因此,研究问题(中断之间的关系构成风格的历史轴线内的城市风光和突然的出现视觉图像),因此,研究旨在确定不连续的原因在风格的视觉序列和突然出现的城市场景的视觉图像。然而,具有很高文化价值的巴格达,由于干预而开始中断,使它的许多部分与周围的城市风格分开。这项研究将依赖于定性方法。研究得出的结论是,Al-Rasheed街的某些城市景观受到视觉干扰,其原因是与个人或政治违法行为有关的社会原因,或与土地价值增加有关的经济原因,以及城市方面的影响,导致拆除或拆除历史建筑。此外,这对拉希德街的模式造成了负面影响。

World highways pavement management system: an overview 世界公路路面管理系统综述
Pub Date : 2023-06-01 DOI: 10.52113/3/eng/mjet/2023-11-01/33-39

In all countries around the world, roads and highways constitute a vital and significant component of the transportation infrastructure and are crucial for the growth of local economies and societies. The term "Pavement Management System" (PMS) refers to a precise and systematized arrangement of defined procedures for collecting, analyzing, maintaining, and reporting pavement data that enables decision-makers to identify the most suitable arrangements and strategies for maintaining the pavements in the functional order for a given specific period at the least profitable cost. To maximize results within a certain budget, the system will next prioritize and suggest pavement rehabilitation and maintenance. The maintenance system in use tracks a variety of elements, including the cost of the activities required to conduct maintenance and the types of materials, personnel, and equipment. After segmenting the road into sections, this technique uses visual or automated field inspection, and its data is subsequently entered into a database. Following the analysis of this data, either by software or by a subject-matter expert, recommendations for the project will be given in the future. Next, based on the budget that is available, the type of surface, and the state of the road, the PMS develops a deterioration curve for each segment of the road. Finally, it chooses the best cost-effective maintenance approach. All of this is precisely accomplished using a PMS, which offers the right pavement treatment at the right time to extend the pavement's life for a reasonable amount longer and at a lower maintenance cost
在世界各国,道路和高速公路是运输基础设施的重要组成部分,对当地经济和社会的发展至关重要。“路面管理系统”(PMS)一词指的是一种精确的、系统化的已定义程序的安排,用于收集、分析、维护和报告路面数据,使决策者能够确定最合适的安排和策略,以便在给定的特定时期内以最低的利润成本维护路面的功能秩序。为了在一定的预算范围内实现效果最大化,系统接下来将优先考虑并建议路面修复和维护。使用中的维护系统跟踪各种要素,包括进行维护所需的活动成本以及材料、人员和设备的类型。在将道路分割成若干路段后,该技术使用视觉或自动现场检查,其数据随后被输入数据库。在通过软件或主题专家对这些数据进行分析之后,将在将来给出项目的建议。接下来,根据可用的预算、路面类型和道路状态,PMS为每段道路绘制出劣化曲线。最后,选择性价比最高的维修方式。所有这些都是使用PMS精确完成的,PMS在正确的时间提供正确的路面处理,以较低的维护成本延长路面的使用寿命
