Abstract: The tanks are an integral part of the supply system and the water distribution network, compensating for fluctuations in consumption throughout the day because of the supply, emergency reserve, pressure balance in the network, and the pump operation's regularization. The steel tanks could have internal physical divisions (vertical cells) whose upper cell has the bottom of the suspended at a height that would guarantee the necessary manometric pressure to meet the said norm. This work aims to evaluate, through numerical analysis, through the Finite Element Method, the structural behavior of three types of vertical water tanks, type bowl, tubular and spherical, with the same volume of reserve composed of an elevated cell, submitted to the hydrostatic and wind actions, dimensioned within the recommendations of the AWWA D100-05 standard through a comparative study of the typologies used in the construction of these tanks through......

Abstract: Traffic congestion causes negative impacts on various aspects of the society and economy. This study evaluates the traffic congestion at road intersections located in Tafila city, Jordan. Traffic and geometric data were collected through a direct field survey at study area. The data were used to simulate the current situation for the selected road intersections using Synchro 10 software. Synchro was used to analyze operational performance for current situation and suggested improvements. After that, a number of improvements were proposed and examined to identify the most reliable improvement for solving traffic congestion at study intersections. The results showed that the absence of traffic control and parking problems were among the greatest causes of delays at the intersections in the city. Therefore, the study recommends that the intersections be controlled using roundabout or traffic light and vehicle parking be strictly prohibited at intersections to reduce traffic congestions and delays..

Abstract: Accidents have been the challenge encountered by the construction industry from its inception; and its impact on construction workers, the industry and the economy are of great concern to the nation. Due to the number of accidents occurrence in construction industry which have been regarded high compared to other industries less prone to accidents. Bearing in mind that success of a project are usually tied to performance and quality, budget and completion of time. Therefore, this study focused on the impact of accidents on construction project success. Questionnaires.....

Abstract: In the present global scenario the usage of plastic is very high and this is return creating a huge environmental impact. Plastics are one of the most commonly used materials in the world today. The huge quantities of these plastic categories currently being marketed bill unlimitedly find their way to the waste dump sides. This is creating waste product problems, due to its high amount of waste generated as an upcoming solution for the existing problem a plastic shredder machine is designed and fabricated. In the present paper a low-cost waste plastic shredding machine is designed and fabricated. The design is carried out......

Abstract: Since the period of high economic growth, the deterioration of social infrastructure, such as bridges and tunnels, has become increasingly serious. To prevent ageing, this infrastructure requires periodic inspection and repair; however, inspection is costly and time-consuming and, hence, there is a strong demand for practical bridge inspection robots to reduce the associated cost and time of inspections. The bridge inspection robot BIREM-IV, as developed in a previous study, uses magnetic rimless wheel and is capable of free movement in steel structures, exhibiting a high running performance. However, because autonomous driving is desired for the practical bridge inspection robot BIREM-IV, it is necessary to install inspection devices — such as sensors and cameras.....

Abstract: Background: Recycling engineering plastics has been a hot topic that has received a lot of attention. Poly (butylene terephthalate) (PBT) is a brittle material that is generally not suitable for certain applications, while the source of toothbrush bristles recycling is enormous. Research on recycled materials not only has a positive impact on the environment but also can reduce material costs by using recycled materials. Materials and Methods: In this research, blends of recycling PBT, which comes from PBT toothbrush bristles, and origin PBT were researched. Tensile strength, flexural strength, Charpy impact testing are studied according to ASTM D638, ASTM D790, and ASTM D256 standard. The samples then were measured through SHORE hardness measurement methods according to ASTM D2240 and microstructure is observed by using a high-resolution FESEM microscope......
