Groundwater Quality Assessment for Irrigation: Case Study in the Blinaja River Basin, Kosovo
Authors: Çadraku Hazir S. 
Published: September 2021

Groundwater is an important source for a drink and irrigation in the Blinaja river basin. Understanding knowledge of irrigation water quality is critical to the management of water for long-term productivity. Historically for this study area there is no data and information regarding the quality and use of water for irrigation needs. Therefore, there was a need to assess water quality based on data analysed from eight sampling points. The purpose of this paper is to evaluate, relying on analytical results, the quality of groundwater in the Blinaja river basin for the purpose of its use for irrigation of agricultural crops. For this purpose, in the Blinaja River Basin in different months during 2015, 2016, 2018 and 2019, 28 water samples were taken to assess the quality of groundwater for irrigation. Water samples were analysed in a laboratory for some of the key quality indicators; pH, EC, hardness (TH), Ca, Mg, Na, K, HCO3, SO4, Cl, etc. and then irrigation water quality indices were calculated such as: percentage of Na (% Na), SAR (Sodium Adsorption Ratio), PI (Permeability index), KR (Kelly's ratio), etc. The overall objective of this study was to assess the quality of water to be used by the inhabitants of the area for irrigation of agricultural crops. Analytical procedures for the laboratory determinations of water quality have been given in several publications (USDA Handbook 60 by Richards, 1954; FAO Soils Bulletin 10 by Dewis and Freitas1970; APHA 2005).

Performance Evaluation of Fatigue and Fracture Resistance of WMA Containing High Percentages of RAP
Authors: Tayyab Saad , Hussain Arshad , Haq Fazal , Khattak Afaq 
Published: September 2021

Sustainability and durability are the key requirements of pavement structure. Sustainability of asphalt pavement structure involves utilization of Warm Mix Asphalt (WMA) technologies with the addition of Reclaimed Asphalt Pavement (RAP), where durability of asphalt involves performance parameters like fatigue and fracture resistance properties etc. Utilizing the RAP content in asphalt mix increases the mixing and compaction temperature which may degrade the performance of asphalt. Hence, numerous studies have recommended different WMA technologies to decrease mixing and compaction temperature of asphalt mix containing RAP. The present research work evaluates the fatigue and fracture performance of WMA and Hot Mix Asphalt (HMA) with varying percentages of RAP and Sasobit. Different mixes of WMA and HMA were designed with varying percentages of RAP (0, 20, 40 and 60%) through Marshall Mix design. Sasobit (organic/wax-based additive) was used as WMA technology to prepare WMA at varying percentages (0, 2, 4 and 6%). The fatigue behavior of asphalt was evaluated using four-point bending test, where fracture resistance of asphalt was determined using Semi Circular Bending (SCB) test in the laboratory. Fatigue and fracture resistance of WMA were improved with the increase in percentages of Sasobit and RAP content, while the addition of RAP in HMA showed a decreasing trend of fatigue and fracture resistance due to the stiffer nature of RAP. Furthermore, WMA was identified as economical for construction besides other benefits like improved properties and environment friendly asphalt mix. Doi: 10.28991/cej-2021-03091741 Full Text: PDF

Published: September 2021

In the area of civil engineering and especially hydraulic structures, we find multiple anomalies that weakens mechanical characteristics of dikes, one of the most common anomalies is erosion phenomenon specifically pipe flow erosion which causes major damage to dam structures. This phenomenon is caused by a hole which is the result of the high pressure of water that facilitate the soil migration between the two sides of the dam. It becomes only a question of time until the diameter of the hole expands and causes destruction of the dam structure. This problem pushed physicist to perform many tests to quantify erosion kinetics, one of the most used tests to have logical and trusted results is the HET (hole erosion test). Meanwhile there is not much research regarding the models that govern these types of tests. Objectives: In this paper we modeled the HET using modeling software based on the Navier Stokes equations, this model tackles also the singularity of the interface structure/water using wall laws for a flow turbulence. Methods/Analysis: The studied soil in this paper is a clay soil, clay soil has the property of containing water more than most other soils. Three wall laws were applied on the soil / water interface to calculate the erosion rate in order to avoid the rupture of such a structure. The modlisitation was made on the ANSYS software. Findings: In this work, two-dimensional modeling was carried of the soil.in contrast of the early models which is one-dimensional model, the first one had shown that the wall-shear stress which is not uniform along the whole wall. Then using the linear erosion law to predict the non-uniform erosion along the whole length. The previous study found that the wall laws have a significant impact on the wall-shear stress, which affects the erosion interface in the fluid/soil, particularly at the hole's extremes. Our experiment revealed that the degraded profile is not uniform. Doi: 10.28991/cej-2021-03091742 Full Text: PDF

Approaches to Determining the Regular Transit Route Duplication Level
Authors: Enin D. V. 
Published: September 2021

Issues of duplication of regular transit routes are of particular importance in the field of transport services provided to population and organisation of passenger transportation from the perspective of ensuring compliance with passengers needs for transportation and of the effects of route duplication on the technical, operational, and economic indicators of performance of these routes and the integral route network.In Russia duplication of regular routes within route networks emerged in the late 1990s – early 2000s in urban transit, other transit modes, and in interconnected transit. In the last decade, these routes have been increasingly subject to revision by local governments and executive bodies of federal constituent entities of the Russian Federation while solving transport planning problems and improving quality of transport services for the population.Evaluation of route duplication, as a rule, is carried out based on the route factor and the route duplication factor, the latter allows pairwise assessment of routes by the length of their overlapping segments.The objective of this article is to show incorrectness of the widespread technique and to present another approach that provides, in the author’s opinion, the correct interpretation of the method for determining the route duplication rate. Achieving this objective is based on methods of theoretical research in the field of organising passenger transportation.In development of this logic, the author proposed a new method for determining the route duplication factor using route adjacency factor, which considers directions and volumes of passenger origin-destination flows. Comparison of existing and proposed approaches is given using simple examples. The results of calculations have confirmed the different nature of factors and the absence of a direct relationship between the needs of passengers for transportation by public transport and the length of adjacent sections of routes. The conclusion is made about probable expediency of using the second (author’s) approach based on the route adjacency factor, which provides a correct solution to the stated transport planning problem. Besides, the possibility of using a new approach when performing diagnostics or designing route networks of different transport modes is shown both in relation to route matching and regarding their clusters and the entire route network.
Prospects for the Use of Artificial Intelligence and Computer Vision in Transport Systems and Connected Cars
Authors: Postolit A. V. 
Published: September 2021

As statistics show, the use of artificial intelligence and machine vision for cars can significantly improve road safety. Even before self-driving vehicles dominate the road, connected vehicles with computer vision-based ADAS will dramatically reduce road accidents. New automotive technologies such as machine vision not only improve road safety, but also open new business opportunities for companies from related industries and sectors such as insurance, car sharing and driver training. Soon, the automotive market, car service services and industries close to transport will change dramatically. This means that those who invest in such developments right now will be able to seize leadership in the era of the spread of innovative technologies.In modern cars, video cameras are used not only as an alternative to the rear-view mirror but are also an important part of active safety systems. Their task, first, is to support collision protection systems through object detection. Cameras are also used to keep track of the lane, to automatically recognise road signs and traffic lights, and monitor the condition of drivers. Together with radars and lidars, they are used to control unmanned vehicles. However, these are far from all the possible areas of useful application of video cameras on board a vehicle. With development of artificial intelligence systems, a decrease in size and an increase in the power of on-board computing facilities, as well as with an increase in the throughput of mobile communications and development of cloud technologies, it becomes possible to implement new services based on video cameras and computer vision.For this reason, the objective of this article is to analyse the trends in development of artificial intelligence, computer vision systems and, considering these trends, to form a list of useful services based on them. The article provides information about what cars can «see» today, how they do it, and what useful services can be implemented for drivers, for transport organisations and for areas related to transport.

Published: September 2021

State-owned Enterprise (BUMN), as one of the pillars of the Indonesian economy, is guided by the outline of the 1945 contusion and the existence of private entities and cooperatives. In principle, the state's involvement in these activities reflects the substance of article 33 of the amendment of the 1945 constitution. One of the missions of BUMN is to serve by innovating. Public policy innovating is a necessity that must be done to overcome problems that exist in society. From the point of view of public policy studies and public services, it can be seen that the government has developed several SOE development strategies that lead the country to face charges in the organizational environment and also to reduce the negative label attached to the bureaucracy. One of the goals of public policy innovation is to improve the quality of public services. The obstacle faced in public policy innovation is that there is no comprehensive study on the development and sustainability of policy innovation in public services in Indonesia

Difficulties in Solving Non-Routine Problems: Preliminary Analysis and Results
Authors: Shawan Muslimah , Osman Sharifah , Abu Mohd Salleh 
Published: September 2021

Students have been taught to solve problems since primary school. However, they still have been having difficulties in solving mathematics problems, especially non-routine problems. By searching errors in mathematics skills and cognitive abilities that have been causing difficulties in solving non-routine problems, this study aims to determine the dominant difficulties that high-achieving students commonly face. A problem-solving test (PST) that comprises four non-routine problems involving algebra was distributed to 56 Form Four selected students through purposive sampling. Each problem is followed by a reflection that allows students to describe the difficulties they face while solving the problem. Hence, the qualitative and quantitative analysis of answer scripts as well as students’ reflection shows that the dominant difficulties faced by high-achieving students when solving non-routine problems are language and information management skills. Poor mastery of these two skills has resulted in students being unable to decipher the problem accordingly which then leads to failing to solve the problems. The findings of this study provide important insight for educators and also researchers in assisting students to deal with their difficulties to solve non-routine problems.
