Abstract: |
The majority of resource allocation methods used today in cell service are found on the singleslope path loss prototype, which does not adequately account for the influence of the physical environment. Cell patterns become more erratic due to the phenomenon of densification, therefore the multislope model is more accurate in approximating the expanded variances in the linkages and intervention. The uplink (UL) of a cell network is being delineated in this study to be as energy-efficient as possible. Every base station (BS), which is arbitrarily distributed throughout a region, is furnished with M antennas to accommodate K user gadgets. With the understanding that pilot sequences are utilised to gather channel state information, a multislope or distance dependent path loss framework is considered. In this situation, the network EE is assessed using a practical circuit power utilization prototype and a lower bound on the uplink SE. The best base station solidity and pilot reuse component for a Massive MIMO web with alternative plots—maximum ratio combining, zero-forcing, and multicell minimal mean-squared error—are first calculated using numerical calculations. No matter the detection method used, the parametric investigation demonstrates that the energy efficiency is a single mode assignment of base station solidity and reaches its paramount for a corresponding low BS density. The energy efficiency is a monotonous non-deductable assignment of BS solidity in the distance independent path loss prototype, in contrast. |

Abstract: |
Cracks are a regular occurrence in structures, and they commonly manifest flaws over time or as a result of the building's construction. There are various reasons for cracks in concrete structures. They may reveal the full amount of the injury or more serious issues. They could indicate serious structural deterioration, a lack of durability, or simply affect aesthetics. Different sorts of cracks arise on structures due to mistakes made during construction and certain unavoidable factors; they are categorized as structural and non-structural cracks. Structural cracks are caused by wrong design, defective construction, poor quality and material, and overloading, all of which can jeopardize a structure's safety. Corrosion of reinforcement, thermal movement, creep movement, chemical reaction, and other factors can cause nonstructural fractures. Cracks in concrete can't be completely avoided, but they can be controlled with the right materials and repair techniques. The goal of this research is to characterize cracks to prescribe optimal maintenance and repair procedures. |

Abstract: |
Electrical resistivity surveying methods have been widely used to determine the thickness and resistivity of layered media for the purpose of assessing Ground Water potential and sitting boreholes in fractured uncontained aquifers using integration of Geophysical and Geospatial techniques. Weighted overlay analysis was used to demarcate the ground water potential zones. The total of 54 VES (Vertical Electrical Sounding) Surveys conducted using DDR-3 instruments in the study area. However, as such the information of one-dimensional geophysical technique for ground water prospecting has often been used to provide more detailed interpretation of the subsurface hydro-geological features, from which successful identified of sites for groundwater potential zone. In this study, 1D vertical electrical sounding applying to produce a subsurface resistivity model for assessing the availability of ground water in the granite gneiss of the study area. The apparent resistivity value of weathered zone varying from 10 to150 Ω-m. The central and north-western part of the study area having resistivity value of 0 to 150 Ω-m. The fracture zone having resistivity ranges from 200-300 Ω-m toward the north-east to south-east region i.e., belongs to moderate to good potential area. Resistivity value of semi-fracture/compact granite formation having high resistivity ranges from 250-500 Ω-m i.e., moderate to poor potential area having towards central part and south-west region belongs to low ground water potential area, electrical resistivity surveys provide detailed subsurface structure and may assist in identifying the configuration of possible fractures which could conduct ground water into shallow subsurface of the study area. It is conducted that electrical resistivity methods are an effective tool for assessing the availability of ground water in the highly weathered and fracture granite gneiss rocks. The result from the study area are more useful for technical ground water management and decision making for installation of suitable bore hole location for long term ground water prospecting. Vertical Electrical Sounding method provides promising input to ground water evaluation in the areas of weathered environment with complex geology. Present study has attempted to identify the groundwater potential zones to solve the groundwater scarcity problem of the study area in hard rock terrain area. |

Abstract: |
The objective of this research was to study the parameters influencing the penetration performed by a welding robot by Gas Metal Arc Welding (GMAW), a material used was ASTM A 36 carbon steel 6 mm thick, type of welding rodER 70S – 6, diameter 1.2 mm, to produce butt welding workpieces without notch to comply with ISO 15614 – 1 by using 100% carbon dioxide gas as a shielding gas, welding wire angle 90 degrees at the extension of the tip of the welding wire 10 mm. The movement of the welding head was in a zigzag pattern (Trapezoid). The welding currents were adjusted into 5 parameters, namely 190, 200, 210, 220 and 230 amps and the welding speed was adjusted into 3 parameters: 0.30, 0.35 and 0.45 meters per second. The experiment was done by welding the workpiece 3 times, each time 5 conditions, total 15 conditions, once completed, the specimen underwent visual testing, dye penetrant testing, tensile testing, flexural testing, macro-structure testing by measuring the volume of deep penetration and hardness. The test results found that the specimens that have undergone the visual testing and the dye penetrant testing, the size of the weld convexity was within acceptable limits. Factors influencing the physical appearance of welds were dependent on the welding current, arc distance, weld speed and the length of the wire ends. Parameters influencing deep penetration when measuring penetration depth and testing strength values were compliant with standards. However, there were notches on some specimen due to incomplete deep penetration. |

Abstract: |
Densities, refractive indices and speeds of sound and their excess properties for 1-butyl-3-methylimidazolium tetrafluoroborate [Bmim] [BF4] with 1-pentanol over the entire range of mole fraction are reported at temperatures ranging from 298.15 K to 313.15 K and atmospheric pressure. Isentropic and excess isentropic compressibility for ionic liquids with 1–alcohols were calculated from the experimental results. The excess values are fitted to the Redlich−Kister polynomial equation to estimate the binary coefficients and standard error between the experimental and calculated values. The measured speeds of sound were compared to the values obtained from Schaaffs' collision factor theory, Jacobson's intermolecular free length theory of solutions and Nomoto’s relation. In addition, the experimentally obtained refractive indices were compared to the calculated values using Lorentz-Lorenz, Dale-Gladstone and Eykman mixing rules. The theoretical results obtained from these relations fairly agrees within the experimental precision. Further, the molecular interactions involved in IL binary mixture system were studied. |

Abstract: |
Densities and speed of sound were measured for the ternary liquid mixtures formed by 1-octanol, cyclohexane and n-pentane at 298.15K and atmospheric pressure over the whole concentration range. Flory model was applied to study the mixing properties and interactions in these liquids. Deviations in the speed of sound and excess molar volume were evaluated and fitted to the Redlich-Kister polynomial equation to derive the binary coefficients and standard errors. An attempt has also been made to study the molecular interactions involved in the liquid mixture from the observed data. Furthermore, excess molar volume and isentropic compressibility for these ternary mixture were computed and correlated with the observed data. Conclusively,it was found that Flory model (non-associated) provides good result when compared with the observed properties. |
