A Comparative Analysis of AutoCAD and NX Siemens Programs in Technical Drawing
Get PDFThis scientific paper aims to analyze and compare the advantages of two prominent computeraided design (CAD) software programs, AutoCAD and NX Siemens, in the context of technical drawing. The paper explores the features, capabilities, and benefits offered by each software, highlighting their respective advantages in enhancing productivity, precision, and collaboration in the field of technical drawing. This analysis provides valuable insights for professionals, educators, and students in selecting the most suitable CAD software for their specific needs
Bearing Capacity of Ring Footing Erected on Wet Gypseous Soil
Get PDFIn this research, (24) experiments were conducted for a ring basis on gypsum soil submerged in water for 24 hours before the examination, where the ratio of inner diameter / outer diameter (Di / Do) is (0, 0.2,0.3, and 0.4) and gypseous soil is of two types: the first soils with a low gypsum content (8.15%) obtained from the Baiji region and the second soils with a high gypsum content (63.42%) from the University of Tikrit. The experiments are conducted using a steel box with dimensions of (900 * 900) mm and a height of (700) mm. The experiments were divided into (12) examinations of flooded soils with low gypsum content using field density (14.87 kN/m3 ), and (12) examinations of dry soil with high gypsum content using field density (13.76 kN/m3 ). Experiments were conducted on a different depth/diameter ratio of the foundation (Df/D) (0, 0.5, and 1). The results showed that the ring footing is better than the circular footing. The best ratio was (Di / Do = 0.4) for all ratios (Df/D). Bearing capacity increases with increasing ratio (Df / D), but this increase is small and gives high subsidence and danger in the initial loading stages that cause the collapse of buildings built on gypsum soil. The tolerability of soils with low gypsum content gave good results compared to the high soil content of gypsum because gypsum dissolves in water in the case of high gypsum-soil
38th parallel: The confrontation between the DPRK and the Republic of Korea
Get PDFThe Korean Peninsula was at one point in history a single unified entity until World War II happened. The Northern half was under occupation by the communist USSR, and the Southern half was occupied by the US. The occupation and the subsequent Korean War ensured that the two nations would take diverging paths that have set them apart to this da
Anodic Processing of Non-Ferrous and Precious Metal Alloys in The Chloride Solution
Get PDFThe rate of anodic dissolution and dependence of current of partial components of the current density Dа for alloys with different Au, Аg and Cu contents have been studied. At high Dа both components of alloy etched with equal rate, whereas at low Dа region of selective dissolution of electronegative components (Аg, Cu) has been observed, a top boundary of which rises with the increasing of Cu contents in the allo

A method for improving Milner-Rabin algorithm to reduce the number of false witnesses
Get PDFNowadays, along with the increase in the volume of data, ensuring its protection is one of the important issues. The best way to ensure data confidentiality is the cryptographic method. One of the main parameters of public-key cryptoalgorithms is a prime number. This paper presents an analysis of probabilistic algorithms to check the primality number and improves the Rabin Milner algorithm to reduce the number of false witnesses
Comparative Characteristics of the Traditional Method in Preparing Cards for Edition and Using Computer Technologies
Get PDFThis article discusses the results of a comparison of two methods for creating maps when preparing them for publication - this is the traditional method using photocopy frames, centrifuges, phototypesetters designed to make dissected positives on plastic according to the elements of the map content, and the method using the AGFA AVANXIS IV digital station for making digital card positives. The concept of blue copies, colorful samples, phototypesetter and digital cards, which are obtained using computer technology programs, is given. The concept of photocopying processes is described when creating publishing originals made by the traditional method and with the help of computer technology

Analysis of Reinforced Concrete Beam Elements Impregnated with Ultra-High-Performance Fibers
Get PDFThe manner of seismic elements made of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) differs significantly from conventional concrete. However, limited research exists in the literature on the dynamic manner of UHPFRC seismic members due to their high cost. Limited element programs can reduce the need for experimental studies to develop design procedures for large-scale seismic elements. Validated analytical models can be utilised to investigate the impact of geometric changes, loading schemes, and reinforcement ratios on the seismic behaviour. This research employed a limited element program, specifically ABAQUS, to model a UHPFRC beam subjected to dynamic loading and evaluate the predictive accuracy of the numerical model. The material model parameters were determined based on uniaxial pressure and tensile tests. The findings from the numerical models demonstrate that the analytical model effectively predicts the dynamic behaviour of UHPFRC beams
