    BRIDGING THE EXPERIENCE GAP: CAN AI COMPENSATE FOR CLINICAL EXPERIENCE IN NEWLY GRADUATED PHYSIOTHERAPISTS AND EXPERIENCED PHYSIOTHERAPISTS?
    (UMT Lahore, 2025) AYESHA TARIQ; EMAN SAFDAR; FATIMA HIBA TULLAH
    Clinical decision making in physiotherapy is influenced by practitioner's experience levels, with newly graduated physiotherapist often facing challenges in confidence and diagnostic accuracy, while experienced clinicians may rely on habitual patterns that do not always align with evolving best practices.

    Connecting two prototype vehicles via fm transmission
    (UMT.Lahore, 2014) AYESHA NISAR; AYESHA TARIQ; RABIA HUSSAIN
    Our FM transmitter and receiver are built with discrete analog components and integrated on three circuit boards. This project designates the design work for our intention to connect to vehicles by implementing of transmitter-receiver technique by means of frequency modulation of range HF i.e. 25MHz. Our design consists of an audio amplifier, VCO (Voltage Controlled Oscillator), crystal COLPITTS oscillator, power amplifier at transmitter side whereas receiver consists of LNA (Low Noise Amplifier), oscillator, mixer, PLL (Phase Locked Loop) and a low pass filter. Our measurement and results are also included in this project. The power of our transmitter is 486mW and receiver is126m W. This receptivity level translates to successful audio reception at distances of almost 30m from the transmitting antenna.

    Preparation of biodiesel from waste eggshells using copper doped calcium oxide catalyst
    (UMT, Lhr, 2021) AYESHA TARIQ
    The utilization of natural energy reservoirs has moved the focus of modern research towards the production of renewable fuels. Biodiesel is an example of renewable fuel. In this research, the preparation of biodiesel through waste vegetable oil was carried out using Cu doped CaO catalyst. The waste eggshells of chicken were used to extract the CaO catalyst. Chicken eggshells were utilized by calcination for 4 hours at 900˚C to obtain calcium oxide catalyst and then doped with a copper transition metal. The wet impregnation method was used to achieve a Cu-doped CaO catalyst. The transesterification reaction was used to convert waste cooking oil into biodiesel. The optimum conditions such as oil to methanol ratio (1:9) and reaction temperature (65˚C) were used for the production of biodiesel using variable catalyst concentrations (1.50% to 3.00% by wt). SEM (Scanning Electron Microscopy) was used for determination of morphology of CaO and Cu-doped CaO. The elemental composition of prepared CaO and Cu-doped CaO was confirmed by EDX (Energy Dispersive X-ray). The presence of Ca-O bond in prepared catalyst was identified by FT-IR (Fourier Transform-Infrared Spectrometry) analysis. Fatty acid alkyl esters present in prepared biodiesel were identified by GC-MS (Gas Chromatography-Mass Spectrometry) analysis. Its properties like cloud point, flash point, viscosity and density were measured and these values of prepared biodiesel matched with standard.
