    A comparative study on effect of curing temperature on the properties of silica fume concrete
    (UMT. Lahore, 2025) Muhammad Haris; Ans Aziz; Zohaib Ahmed; Shayan Tariq
    This thesis investigates the influence of curing temperature on the mechanical and physical properties of concrete incorporating silica fume as a partial cement replacement. Silica fume, known for its pozzolanic reactivity and ability to enhance concrete strength and durability, was evaluated under various curing conditions including ambient curing, steam curing, and water curing. The experimental findings of this study demonstrate that incorporating silica fume as a partial replacement of cement significantly influences the strength development and workability of concrete. It was observed that higher dosages of silica fume negatively affect workability due to increased water demand, attributed to its high fineness and surface area. However, replacement levels between 5% and 15% yielded the most favorable results, offering an optimal balance between workability and compressive strength. At early ages (3 days), concrete mixes within this replacement range showed improved strength development, indicating the initiation of the pozzolanic reaction. This trend is consistent with previously published literature and confirms that silica fume enhances early-age performance without compromising fresh properties when used in moderate quantities. Moreover, the strength of concrete continued to increase at 28 days, as the pozzolanic reaction became more pronounced over time, contributing to a denser microstructure and higher compressive strength. Additionally, curing at elevated temperatures (such as 37°C) was found to accelerate the rate of hydration and pozzolanic activity, resulting in higher early-age strength compared to curing at ambient or lower temperatures. Overall, the study concludes that 5–15% silica fume replacement, combined with proper temperature-controlled curing conditions, can significantly enhance the mechanical properties of concrete, especially in strength development, while maintaining acceptable workability.

    Ai-powered real estate platform with renovation services
    (UMT.Lahore, 2025) Bilawal Hassan Dogar; Abdullah Khan; Ali Husnain; Husnain Ali; Muhammad Haris
    Gharbaar Estate is an Artificial Intelligence-based real estate portal that helps to solve one of the main problems in the Pakistani property market -the absence of a single platform to buy/sell a house and secure a renovation service. Maximizing utilization of existing systems: Existing systems are scattered and causes inefficiency in the processes, poor communications and support and no consolidated support. Our project filled this gap through the unification of these services into a single digital platform. Its fundamental aspirations are the consolidation of property listings and renovation services, the facilitation of natural language-based property finding, the provision of AI-based renovation recommendations on uploaded property photographs, the association of a user with verified renovators, and lastly the provision of safe, transparent, and legal transactions. It is developed on MERN stack (MongoDB, Express.js, React.js, Node.js), RESNET50 will be used in renovation analysis, NLP will be used to make searching properties intuitive, communicate in real-time by using Socket.io, and utilize Google Maps API as the location mapping tool, and it will deploy Render and MongoDB Atlas. The system is self-contained with customized dashboards by buyers, sellers, and renovators, AI-connective modules of renovation tips, and chat responsiveness. The results of the testing demonstrated 86 percent accuracy in the predictions of the renovation and a 70 percent saving of time in search result using natural language input. These can be seen as results of enhanced user interaction and decision-making when compared with the old platforms. Conclusively, Gharbaar Estate automates the process of buying/selling property and carrying out home improvement into an easily navigable AI- supported journey that makes individuals invest wiser and develop trust among all parties. The areas of future improvement are augmented reality-based previewing of renovations and the regional language support to make it more approachable.

    Determination of antifungal activity of different medicinal plants against candida species from clinical origin
    (UMT Lahore, 2022) Muhammad Haris; Aqsa Azam; Mushrra Ashraf; Syeda Ansharah Fatima
    The current study aimed to evaluate the in vitro antifungal potential of Parthenium hysterophorus, Datura stramonium, Calotropis procera, and Origanum vulgare leaf extracts against Candida isolates, using distilled water, n-hexane, chloroform, ethanol, and ethyl acetate as solvents. Morphological identification of the isolates was performed through lactophenol and Gram staining, while Chromagar was used as a differential medium for species identification. Antifungal activity and minimum inhibitory concentration (MIC) were determined using the well diffusion method. All plants except Calotropis procera exhibited antifungal activity. Among them, Parthenium hysterophorus showed the highest zone of inhibition (ZI) against the B0 isolate, Datura stramonium against B9, and Origanum vulgare against Sp2. Maximum ZI was observed in ethyl acetate, ethanol, and n-hexane extracts of Parthenium hysterophorus and Datura stramonium. MIC was evaluated at 25, 50, 100, and 200 mg/ml, with minimum fungicidal concentration (MFC) determined to confirm fungicidal efficacy. Origanum vulgare extracts at 100 and 200 mg/ml completely killed SP2 growth in all solvents except ethyl acetate, which showed inhibitory effects. Datura stramonium completely inhibited B9 and T.A isolates at 100 and 200 mg/ml in all extracts, while 200 mg/ml was required to inhibit BO and Sp2 isolates. Parthenium hysterophorus at 200 mg/ml completely killed B9 in all solvents, while BL exhibited MIC in most extracts. Overall, the study concludes that Parthenium hysterophorus, Datura stramonium, and Origanum vulgare possess significant antifungal activity against Candida isolates, whereas Calotropis procera showed no activity.

    Evaluating wind energy potential in Pakistan�s three provinces, with proposal for integration into national power grid.
    (Renewable and Sustainable Energy Reviews, Elsevier, 2015) Jameel Ahmad; Raheel Zafar; Muhammad Haris
    Pakistan is facing increasing power shortage from the last two decades. The Government of Pakistan (GoP) has taken various remedial measures and is offering incentives for private investment to generate electricity at cheap rates. New hydropower dams were proposed in the past, such as Kalabagh Dam, but could not be commissioned to date. Fossil fuels are depleting and oil has to be imported for oil-fired power plants, which is highly expensive and a burden for the country's economy. This scenario has raised serious concerns among citizens. In this frustrating situation, there is dire need for exploration and installation of alternate renewable energy resources, in particular, wind energy and solar energy to augment the existing power generation and distribution apparatus. These then need to be integrated with the national power grid. Pakistan has enormous wind energy potential, especially in three of its four provinces namely, Khyber Pakhtun Khwa (KPK), Sindh and Balochistan. The country's multifarious terrain includes coastal and hilly areas suitable for installation of large wind turbines. The GoP has taken active steps towards measuring wind speed statistics in various parts of the country. In this paper, the authors analyze wind speed data for the mentioned three provinces. The fourth province, Punjab, has very limited wind energy potential and hence is not considered. Wind speed data for Jiwani (a reference site in Balochistan) was obtained from Pakistan Meteorological Department (PMD) as a case study. The paper attempts to assess how much wind energy can be harnessed from the three provinces. It then focuses on Jiwani whose specific power density is estimated for wind turbine sizing. Lastly, a practical scheme is proposed for integration of wind power output (from windy sites) with the national power grid.

    Improved fuzzy logics based differential protection scheme
    (International Power Engineering and Optimization Conference, 2013) Muhammad Haris; Muhammad Salik; Ali Arslan Safdar; Umer Rashid
    In this research work, fuzzy logics based differential protection scheme is proposed for power transformer. Membership functions are developed from voltage, frequency and currents at primary side and secondary side of the power transformer. The proposed protection scheme senses the operating conditions and gives trip or no trip signal to the circuit breaker from the fuzzy inference of the small, medium and high values of the membership functions. Simulation results of various operating conditions, shows that the proposed differential relay is reliable, fast and is able to discriminate between internal faults, external faults and magnetizing inrush current. Results also demonstrate selective phase switching and auto-reclosing function of the protection scheme. Fuzzy logics based protection scheme is modeled in MATALAB-SIMULINK environment.

    In-silico drug designing against selected Covid-19 disease causing proteins
    (2022) Muhammad Azeem Sajjad; Mahnoor Javed; Aleeza Ahmed; Muhammad Haris
    COVID-19 is the deadliest threat to humankind after the pandemic of Influenza in 1918. Emerging from District Wuhan of China, coronavirus disease started spreading to the world with high infection and mortality rates, especially affecting aged and comorbid persons, disturbing the socio-economic balance worldwide. This disease is caused by SARS-CoV-2, which is an RNA virus with a genome length of 29,811 nucleotides and 6 open reading frames (ORFs). ORF1a is responsible for translating the 16 non-structural proteins (NSPs). Among these 16 non-structural proteins, Nsp9, Nsp15, and Nsp16 are responsible for replication, nuclear transport, transcription, host immune cell evasion, and complete translation of SARS-CoV-2. These NSPs are conserved in nature and maintain their functionality precisely. There is another protein, Transmembrane serine protease 2 (TMPRSS2), which is a human endothelial cell surface protein required by the virus to enter the cell. Considering their functions, all four proteins are potential drug targets. In this study, computational techniques were applied to detect probable inhibitors from the well-characterized ASINEX library containing 145,843 molecules. After strict ADME filtration of compounds, the resulting 77 compounds were docked with their respective target proteins. After docking, the behavior of compounds with good dock scores was observed at the quantum mechanical level, predicted and analyzed through DFT calculations. The stability of protein and ligand at the molecular level under artificial conditions was observed using MD (Molecular Dynamics) simulation tools. Three compounds were isolated, fulfilling all the requirements of potential drugs against Nsp15, Nsp16, and TMPRSS2. Compounds obtained by this method would be subjected to in-vitro and in-vivo analysis to check their efficacy in the treatment of COVID-19.
