      • Designing a Remote Electronic Irrigation and Soil Fertility Managing System Using Mobile and Soil Moisture Measuring Sensor

        Asim Seedahmed Ali, Osman,Eman Galaleldin Ahmed, Kalil International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.12

        Electronic measuring devices have an important role in agricultural projects and in various fields. Electronic measuring devices play a vital role in controlling and saving soil information. They are designed to measure the temperature, acidity and moisture of the soil. In this paper, a new methodology to manage irrigation and soil fertility using an electronic system is proposed. This is designed to operate the electronic irrigation and adds inorganic fertilizers automatically. This paper also explains the concept of remote management and control of agricultural projects using electronic soil measurement devices. The proposed methodology is aimed at managing the electronic irrigation process, reading the moisture percentage, elements of soil and controlling the addition of inorganic fertilizers. The system also helps in sending alert messages to the user when an error occurs in measuring the percentage of soil moisture specified for crop and a warning message when change happens to the fertility of soil as many workers find difficulty in daily checking of soil and operating agricultural machines such as irrigation machine and soil fertilizing machine, especially in large projects.

      • Design and Implementation of Low-Cost Articulate Manipulator for Academic Applications

        Muhammad Asim Ali,Farhan Ali Shah International Journal of Computer ScienceNetwork S 2024 International journal of computer science and netw Vol.24 No.1

        The objective of this work is to design a low cost yet fully functional 4-DOF articulate manipulator for educational applications. The design is based on general purpose, programmable smart servo motors namely the Dynamixel Ax-12. The mechanism for motion was developed by formulating the equations of kinematics and subsequent solutions for joint space variables. The trajectory of end-effector in joint variable space was determined by interpolation of a 3rd order polynomial. The solutions were verified through computer simulations and ultimately implemented on the hardware. Owing to the feedback from the built-in sensors, it is possible to correct the positioning error due to loading effects. The proposed solution offers an efficient and cost-effective platform to study the trajectory planning as well as dynamics of the manipulator.

      • Inquiring Prescriptions Using Geographic Information System (GIS)

        Osman, Asim Seedahmed Ali,Kalil, Eman Galaleldin Ahmed International Journal of Computer ScienceNetwork S 2021 International journal of computer science and netw Vol.21 No.spc12

        Geographic Information Systems (GIS) is considered to be one of the most important technologies provided by the Internet in our era. GIS enables institutions and individuals to plan and make decisions in many fields. GIS assists in accessing new and updated information on planning process. GIS also enables determining distances such as length, width, area on a map, and allows analyzing and processing a large amount of data for the search of geographical characteristics of locations. This paper explains the concept of dispensing prescription through the specific code of drug on an electronic system using GIS technology. The proposed methodology aims to inform patients of all the prescriptions dispensed and to help individuals inquiring about prescription at the nearest pharmacy through GIS technology. This proposed methodology is considered significant in some cases, as the patient does not know price, specifications and pharmacy location where the drug required is available, thus increasing the time and effort cost that is spent searching for the prescription.

        Inorganic nanocrystal-carbon composite derived from cross-linked gallic acid derivative of polyphosphazenes for the efficient oxygen evolution reaction

        Ali Zahid,Mushtaq M. Asim,Abbas Yasir,Liu Wei,Wu Zhanpeng 한국탄소학회 2023 Carbon Letters Vol.33 No.3

        The development of heteroatoms doped inorganic nanocrystal-carbon composites (INCCs) has attained a great focus for energy applications (energy production and energy storage). A precise approach to fabricate the INCCs with homogenous distribution of the heteroatoms with an appropriate distribution of metal atoms remains a challenge for material scientists. Herein, we proposed a facile two-step route to synthesize INCC with doping of metal (α-Fe2O3) and non-metals (N, P, O) using hydrogel formed by treating hexachlorocyclotriphosphazene (HCCP) and 3, 4, 5-trihydroxy benzoic acid (Gallic acid). Metal oxide was doped using an extrinsic doping approach by varying its content and non-metallic doping by an intrinsic doping approach. We have fabricated four different samples (INCC-0.5%, INCC-1.0%, INCC-1.5%, and INCC-2.0%), which exhibit the uniform distribution of the N, P, O, and α-Fe2O3 in the carbon architecture. These composite materials were applied as anode material in water oxidation catalysis (WOC); INCC-1.5% electro-catalyst confirmed by cyclic voltammetry (CV) with a noticeable catholic peak 0.85 V vs RHE and maximal current density 1.5 mA.cm−2. It also delivers better methanol tolerance and elongated stability than RuO2; this superior performance was attributed due to the homogenous distribution of the α-Fe2O3 causing in promotion of adsorption of O2 initially and a greater surface area of 1352.8 m2/g with hierarchical pore size distribution resulting higher rate of ion transportation and mass-flux.

        A Study of Aerosol Properties over Lahore (Pakistan) by Using AERONET Data

        Muhammad Ali,Salman Tariq,Khalid Mahmood,Asim Daud,Adila Batool,Zia-ul-Haq 한국기상학회 2014 Asia-Pacific Journal of Atmospheric Sciences Vol.50 No.2

        It is well established that aerosols affect the climate in avariety of ways. In order to understand these effects, we require aninsight into the properties of aerosols. In this paper we present a studyof aerosol properties such as aerosol optical depth (AOD), singlescattering albedo (SSA) and aerosol radiative forcing (ARF) overmega city of Lahore (Pakistan). The data from Aerosol Robotic Network(AERONET) have been used for the period December 2009 toOctober 2011. The seasonal average values of AOD, asymmetryparameter (ASY) and volume size distribution in coarse mode wereobserved to be highest in summer. On the other hand, the averagevalues of Angstrom exponent (AE) and imaginary part of refractiveindex (RI) were found to be maximum in winter. The average valueof real part of RI was found to be higher in spring than in all otherseasons. The SSA exhibited an increasing trend with wavelength inthe range 440 nm - 1020 nm in spring, summer and fall indicating thedominance of coarse particles (usually dust). However, a decreasingtrend was found in winter in the range 675 nm - 1020 nm pointingtowards the dominance of biomass and urban/industrial aerosols. Asfar as aerosol radiative forcing (ARF) is concerned, we have foundthat during the spring season ARF was lowest at the surface of Earthand highest at top of the atmosphere (TOA). This indicates that theatmosphere was warmer in spring than in all the remaining seasons.

        Effect of electrochemical reduction on the structural and electrical properties of anodic TiO2 nanotubes

        Muhammad Asim Rasheed,Kamran Ahmad,Nilem Khaliq,Yaqoob Khan,Muhammad Aftab Rafiq,Abdul Waheed,Attaullah Shah,Arshad Mahmood,Ghafar Ali 한국물리학회 2018 Current Applied Physics Vol.18 No.3

        The effect of electrochemical reduction on the structural and electrical properties of amorphous as well as annealed TiO2 nanotubes (TNTs) is investigated under ambient conditions. TNTs were prepared by anodizing titanium sheet in ethylene glycol electrolyte containing NH4F and de-ionized water at 40 V for 6 h. Electrochemical reduction is carried out in 1 M aqueous KOH solution for ~15 s at 3 V. TNTs are characterized by SEM, XRD, XPS and impedance spectrometer. XRD results confirm an increase in dspacing for (101) and (200) planes, after electrochemical reduction. XPS data reveal that electrochemical reduction produced prominent shifts of ~0.7e1.0 eV in the binding energies of TNTs. Interestingly, these shifts recover completely (in case of amorphous TNTs) and partially (in case of anatase TNTs) within ~7 days after reduction process due to oxygen uptake. Partial recovery in the binding energies of anatase TNTs is due to the fact that the oxygen vacancies are thermodynamically more stable as compared to amorphous TNTs. Similarly, the electrochemical reduction process decreases the impedance values of TNTs by more than three orders of magnitudes (from MU to kU). The impedance values also recover to the similar values before reduction in a span of ~7days.

        Morphology controlled facile synthesis of MnO2 adsorbents for rapid strontium removal

        Umar Asim,Syed M. Husnain,Naseem Abbas,Faisal Shahzad,Abdul Rehman Khan,Tahir Ali 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.98 No.-

        MnO2 nanostructures with three distinct architectures, namelyflower, balk and tube-like, have beensynthesized through a single step microwave assisted hydrothermal method at different reactiontemperatures (110 C, 140 C and 180 C). The characterization of as prepared MnO2 samples wereperformed by means of Fourier transform infrared spectroscopy, X-ray diffraction, scanning electronmicroscopy, and transmission electron microscopy. The N2 adsorption–desorption isotherms revealedthe higher specific surface area and porosity of theflower like MnO2 as compared to balk and tube-likeMnO2. The adsorption behavior of as prepared adsorbents was investigated towards Sr2+ radionuclide. Because of the hierarchal structure and the high surface area (62.64 m2/g), MnO2-110 depicted the bestSr2+ adsorption performance with maximum adsorption capacity of 52 mg/g at pH 6 as compared to otherMnO2 morphologies synthesized at 140 C and 180 C. The kinetic studies revealed that the adsorption ofSr2+ onto MnO2-110 followed the pseudo-first-order model whereas the adsorption equilibrium dataobeyed the Freundlich and Sips model. Moreover, the MnO2-110 adsorbent reached the steady statequickly ( 10 min) and is capable to bind Sr2+ in slightly acidic to alkaline solutions.

        On the relationship between the porosity and initial coulombic efficiency of porous carbon materials for the anode in lithium-ion batteries

        Majid Shaker,Ali Asghar Sadeghi Ghazvini,Reza Riahifar,Asim Mumtaz 대한금속·재료학회 2022 ELECTRONIC MATERIALS LETTERS Vol.18 No.4

        Herein, we present a new model to investigate the cause of the low initial coulombic efficiency of lithium-ion battery (LIB)porous carbon anodes and discover its relationship with the porosity of these materials. According to the proposed model,the capacity of porous carbon LIB anodes is in a direct relationship with their porosity, which reduces by the formation ofthe solid electrolyte interphase (SEI) layer occupying the cavities and decreasing the accessible surface area for the electrolyte. The introduced model in this study was compared with the data published in the literature and revealed a satisfactoryagreement with them. As a result, it was concluded that the fraction of the mesopores occupied by SEI after the 1st cyclefluctuates around the value of 0.5 and is mostly in the range of 0.6−0.4. Thereby, it can be employed for the prediction ofthe first cycle coulombic efficiency (CE) of carbonaceous anodes as LIB anodes and optimization of their structure.
