While the SINTACS method is widely used, it has limitations by not adequately considering hydrogeological parameters and supplementary data. To address SINTACS limitations, a modified approach (MSVILuLn) incorporates land use/cover and lineaments. Parameter weights were determined using analytic hierarchy process (MSVILuLn-AHP) and network process (MSVILuLn-ANP). Raster layers of nine parameters were analyzed in GIS to evaluate groundwater vulnerability index using SINTACS, MSVILuLn, MSVILuLn-AHP, and MSVILuLn-ANP. Nitrate concentrations from 48 wells were compared to validate results. MSVILuLn-ANP identified more very high/low vulnerability zones compared to others. It showed highest accuracy (91.7%) correlating vulnerability and nitrate levels. MSVILuLn-ANP offers a more comprehensive vulnerability assessment for groundwater management in Raipur city. Integrating SINTACS with GIS and objective weighting methods enhances spatial analysis of sensitive areas and prevents contamination.","PeriodicalId":192480,"journal":{"name":"International Journal of Current Engineering and Technology","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135218850","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 proposed antenna consists of a triangular director, a coplanar waveguide (CPW) to coplanar stripline (CPS) transition line, and the RIB. The proposed triangle director substitutes a typical director of a planar quasi-Yagi dipole antenna. The triangle director has modified a director of a planar quasi-Yagi dipole antenna. The triangle director generates a circular polarization. Also, the RIB has proposed to match an impedance between the CPW-fed to the CPS transition line. It obtains an ultra-wide frequency band of 4020 MHz (2160 - 6180 MHz), and a peak realized gain of 12.5 – 6.2 dBi in the operating frequency band. The proposed antenna shifts the resonant frequency to a lower frequency band of 75% than the typical planar dipole antennas. The proposed antenna uses widely for wireless medical communication, both ISM bands and C-V2X applications.","PeriodicalId":192480,"journal":{"name":"International Journal of Current Engineering and Technology","volume":"57 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113973744","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}

In general, water pollution is a resultant of agricultural and industrial activities. We handpicked 150 samples of drinkable water from various parts of the Faisalabad City. The findings revealed that locations fed by industrial waste matter had higher nitrate level, whereas places with superior drainage had lower nitrate content. Almost all the factors in general produced major effects on the leaching of fertilizer (NO3-N) into the soil outline. The current research found that nitrogenous fertilizer in the form of NO3-N was leached up to 150 cm into the soil. In Pakistan, the water table was within 150 cm of the ground surface on 30 percent of the 41 million acres examined. The municipal and industrial wastes of Faisalabad cannot be separated, as industries are situated in residential areas. The mixture is discharged into open land or into drains. None of the samples contained Zn in the tolerance limit (TL refers to the concentration higher than maximum permissible limit). MPL decrease with an increase in distance of the source from the sullage carrier. Fe, Cu and Mn, the results indicate that the sullage carrier has contaminated the ground water up to 300 meters and no water sample was found within TL within 300 meters distance. The results indicate that Fe, Cu, and Mn concentration in ground water has reached to problematic level along unlined section of the sullage carrier. Thus, in this zone a severe Fe, Cu and Mn toxicity has been identified. Pb however, the situation was somewhat different because none of the samples was found within TL after 50 meters distance of source from such sullage carrier. The result of Fe indicates problem in some water samples collected along lined section of sullage carrier. The same situation prevailed for Cu and Mn. Both the metals have contaminated the ground water up to 150 meters. The results of Pb were similar as in case of unlined section of the sullage carrier but it has some problem up to 25 meters. This paper describes some aspects of surface and subsurface water pollution, in addition to best management practices and remedial measures required for minimization environmental hazards.","PeriodicalId":192480,"journal":{"name":"International Journal of Current Engineering and Technology","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130976874","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}

If in real practice these have to be obtained, it is necessary that the operating regime has to be changed so it is necessary and better to build a control system that regulates the electrical machine [for example starting of the m/c, stopping of the m/c, accelerating, retarding reversing, , braking, etc.) This paper presents an analysis of power, voltage, speed and current of DC motor drive using Matlab simulation. Variable speed drives that are variable and are in rotating motion of the electrical devices such as DC motor drive that are used to regulate the speed. Besides this it accelerates and gives a direction of movement. Electrical variable speed drives consist of three components: A controller of high level that can accommodate the use of various switches/buttons and potentiometers for starting, stopping, and changing the speed; the controller of the drive that is enable to converts the fixed voltage and frequency of power source of AC type in power output of adjustable type for controlling the electric drive motor in the specific permitted speed ranges, also control the drive motor that is capable of converting electrical energy into the movement of the motor. Variable speed drives that may finely and smoothly regulate the speed to any desired value within the design constraint and to a predefined working range can be taken as a particular approach to regulate electrical equipment and improving the various processes in which the electrical machines are involved. It was found from results of simulation that the output voltage of the rectifier, speed, torque and current ripples can be represented specially in single-phase models. In 3-phase model which has 3 inputs voltage and base voltage, an instrument to measure the power factor is added, which is equal to tan-1(Q/P), it can be noticed that the mean value of power factor at low speeds (0-2) seconds is 0.053, while at high speeds it reaches to 0.93 which means that the motor should worked at its related speed needed for the application. i.e. we should use the motors related to the needed RPM because the power is improved and at the end the efficiency is more. Steady-state regions are a good area used to measure input powers, while at transient or unsteady areas the values of power, current, torque and voltages has a big actuating error","PeriodicalId":192480,"journal":{"name":"International Journal of Current Engineering and Technology","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125830376","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}
