The Jordan Engineers Association poll in 2020 found that variation orders (VOs) accounted for 23% of cost overruns in construction projects in Jordan. Research undertaken by the Ministry of Public Works and Housing in 2019 found an average of 948 change orders per year, representing 25.5% of the total value of the projects. Our study introduces a highly tailored evaluation method to gauge the effectiveness of Building Information Modelling (BIM) in addressing these challenges. The study assesses the efficacy of Building Information Modeling (BIM) in diminishing variation orders (VOs) by examining sophisticated BIM functionalities. The study employs an intricate case study and diverse construction project data to construct a model that assesses the capacity of BIM to reduce project modifications and enhance cost efficiency. A novel approach has been devised to enhance the optimization of building information modeling (BIM) in the construction industry of Amman, Jordan. The objective of the concept is to minimize variation orders (VOs) and enhance project management. The study employs research approaches, such as semi-structured interviews and questionnaires, to pinpoint the essential abilities contributing to change orders. After comprehensively analyzing BIM's global and Middle Eastern applications, we created the model. The findings indicate that enhancing Building Information Modeling (BIM) capabilities can effectively mitigate the occurrence of variation orders within Jordan's building sector. The approach promotes the cooperation of stakeholders, sets quantifiable benchmarks, and strategically employs BIM for preliminary risk assessment. This research substantially enhances the productivity and cost-effectiveness of construction projects in Jordan, offering vital insights for professionals and policymakers.","PeriodicalId":431188,"journal":{"name":"Journal of Advanced Sciences and Engineering Technologies","volume":"105 49","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141124718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This document primarily focuses on the study method and the two components of active patch arrays. The radiation models were computed utilizing the cavity plate model, the Simple Green model, and the rigorous commercial Electromagnetic Simulator. The active rectangular patches with the Gann diode were reconfigured and assembled into arrays in the E-plane and H-plane. The calculated and measured findings for both active arrays have proved the potential for beam scanning. All three models have accurately projected radiation levels across a wide range of steering controls. To ensure stable operation, a thin dielectric layer was positioned in front of the H plane of the array. The impact of the dielectric layer on the even and odd modes of the array has been demonstrated.","PeriodicalId":431188,"journal":{"name":"Journal of Advanced Sciences and Engineering Technologies","volume":" 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140995546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The next generation of communication, 5G aims to connect people and things via intelligent networks, but current network architectures struggle to handle massive data traffic. The spatial domain of the fiber is highly useful for handling this massive data traffic.

Five Reynolds numbers (based on inlet height channel) are studied (Re = 100, 200, 400, 800, 1200) with a constant heat flux on cylinder surface (q^''= 5000 W/m^2), and S_T = 1.5D, 2D, 3D, the D is triangle side length.

The influences of severalenvironmental parameters including pH of the solution, initial PCP concentration, dosage of Al2O3 and dissolved ozone concentration were also investigated. The highest degradation efficiency of PCP was achieved at conditions: pH 8, 1.87 g/LAl2O3, and 0.49 g/L dissolved ozone concentration. The catalytic activity of Al2O3 was linked to highly hydroxylated surface. The surface hydroxyl groups on Al2O3 were the active places during catalytic ozonation.

Unfortunately, it may easily be exploited by attackers (For instance, in cases when the language is altered for specific goals, illegal access to the material or its abuse is possible.) To solve this problem, we embed secret texts (ST) within seemingly innocuous cover texts (CT) so that we can track CT for modifications. Based on the findings of this study, a method is provided for ST embedding in CT in which binary ST digits are converted to CT binary digits through Characters in ASCII (containing whitespace, punctuation, and special characters). Before commencing the embedding procedure, Using a One-Time Pad (OTP), the ST text was translated into ciphertext, and the value of each character was changed into a binary integer with a length of seven bits. As opposed to the ST text, which required additional time to encode, the CT text could be converted into a binary integer using just the first seven bits. During the embedding process, It was decided to swap the first bit of the ST character for the first bit of the CT character, which both had the same amount of bits (putting the first bit of the ST character, for example, on the same line as the first bit of the CT character). Any piece of ST that was recorded on any bit of CT served as a stage key. Extracting ST from CT requires the stage key. The embedded information served effectively as text steganography or watermark, and the CT's appearance was unaffected by the embedding procedure. In other words, the 1 character of ST might be concealed by using 7 CT characters. Also, a Jaro-Winkler Distance of 1 meant that the stage texts made couldn't be told apart from CT by looking at them.","PeriodicalId":431188,"journal":{"name":"Journal of Advanced Sciences and Engineering Technologies","volume":"127 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114044689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dead Sea water is a hazardous environment for concrete due to high concentration of salts. The aim of this study was to investigate the effect of Dead Sea water on the compressive strength of concrete containing hydrophobic water-repellent admixture, and to determine the optimum dosage of admixture to be used to reduce this effect. Three types of cement were used (Ordinary Portland Cement, Pozzolanic Cement, and Sulphate-Resisting Cement) with various dose rate of hydrophobic water repellent admixture (0%, 2%, and 4% of cement weight). An experimental approach, in which the specimens were divided based on the type of cement and the specimen’s age, was adopted. Nine control cubic specimens were cured in plain water to ensure that the required compressive strength was reached and (54) specimens were cured in Dead Sea water. The specimens cured in Dead Sea water were tested at 7 and 28 days to investigate the effect of Dead Sea water on the early and long-term strength. The results showed that a reduction in the 28-day compressive strength occurred in all specimens for the three types of cement used, but with the addition of water repellent, this reduction was alleviated, and the optimum percentage of admixture was 2% of cement weight.","PeriodicalId":431188,"journal":{"name":"Journal of Advanced Sciences and Engineering Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128696999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
