Lahore, 2025) Muhammad Haris; Ans Aziz; Zohaib Ahmed; Shayan TariqThis 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.Item A comparative study on strength(UMT. Lahore, 2025) Ali Riaz; Umair Ahmed Qureshi; Muhammad UmerRafique; Shah KhalidConcrete is one of the most commonly used construction materials, and its properties can be modified using additives like air-entraining agents (AEAs) and supplementary cementitious materials. This study focuses on the effects of AE192, an air-entraining agent, on the mechanical and physical characteristics of ceramic concrete blocks, comparing them to traditional first-class bricks. The objective was to evaluate how different percentages of AE192 (5%, 8%, and 10%) influence compressive strength, weight, and workability, while also incorporating fly ash and ceramic powder for sustainability. A 1:2:4 mix design was used, with Bestway OPC Grade 43 cement, Lawrencepur sand, and 9.5 mm coarse aggregate. Fly ash replaced 20% of cement, and ceramic powder replaced 15% of sand. Two sample sets were tested at 7, 14, and 28 days for compressive strength and weight, following ASTM standards for slump, specific gravity, bulk density, and compression testing. Results showed the control mix (0% AE192) had the highest compressive strength (2030.56 PSI in Sample 1 and 1269.44 PSI in Sample 2), making it suitable for structural applications. The 5% AE192 mix showed balanced strength and reduced weight (1841.67 PSI and 733.33 PSI), making it ideal for semi- structural use. Higher AE192 levels (8% and 10%) led to reduced strength but improved workability and freeze-thaw resistance, useful for non-structural applications. Ceramic- enhanced blocks, especially with 10% ceramic powder, achieved 1186.11 PSI, offering a sustainable option. Although first-class bricks had higher strength, they were less sustainable. The study concludes that 5% AE192 offers an optimal balance of strength, workability, and sustainability.Item A hybrid mppt technique for solar photovoltaic system under partial shading(UMT.Lahore, 2019) Tayyab RaeesFor energy production, renewable sources are prevailing than non-renewable sources because of their non-polluting and less contaminating characters. Solar energy is emerging as a greater source of electricity production. By using PV solar panels, solar energy is being converted into electrical energy. However, to examine the maximum power point and to overcome the limitations of environmental change is the major problem in this photolytic system. The purpose of this research is to resolve the limitations of different techniques with high convergence rate, low complexity, and fewer fluctuations as compared to other techniques. There are two different techniques, one is incremental conductance (direct tracking technique) and second is fractional open-circuit voltage (indirect tracking technique). This research provides the hybrid technique of FOCV and IC, which works in partial shading, uniform, and the static environment as well to maximize the power output. The proposed technique is extremely useful as it results in improvement of the efficiency and reduces the cost of the PV module, easy to install, and has a low maintenance cost. The whole algorithm has been implemented via two steps. In the first step, fractional open circuit voltage divides the whole power voltage curve into many sections and then estimates the section in which the global maximum point is possible to achieve. In the second step, incremental conductance run and find out the exact peak. The efficiency of this module is checked by comparing its results with other MPPT methods by using MATLAB/SIMULINK. Comparison has clearly shown that Improve Incremental conductance is more efficient and suitable in different shading conditions. Keywords; FOCV, Improved IC, Hybrid MPPT model.Item A lean approach to improve efficiency by using VSM in excel engineering (PVT)(UMT, Lahore, 2016) Ali Arslan, Muhammad Zawar, Sohaib Ariz and Abdul RazzaqThe project that we decided to perform is about value stream mapping, and to perform this project we chose a manufacturing (excel engineering) industry.

The occurrence of some problems like jitter, quantization errors, integral nonlinearity and conversion time reduces the performance of DAC. One of the most efficacious ways to combat these problems is the use of Sigma Delta Modulation (SDM) in DAC. This work emphasizes on the designing of Multi-order SDM to achieve high resolution DAC consuming low power and high SNR. The increase of oversampling ratio (OSR) requires the high speed DAC, overloads the quantizer, eventually reduces the DAC speed and increases the power consumption. Similarly, the complexity of the transistor circuitry in VLSI technology implementation increases as the order of SDM increases. Hybrid MASH-EFM architecture is used to overwhelm the above two conditions. MATLAB simulation will be used for comparison of different Multi-order SDM architectures to study the effect on DAC performance. Different performance parameters are recorded at different OSR’s of different architectures (MASH, EFM and Hybrid MASH-EFM).1st order Hybrid MASH-EFM SDM achieves high SNR equal to 131.7 db and ENOB of 16 bits at OSR of 5. These results reveal that the proposed architecture (Hybrid MASH-EFM) is superior to two existing architectures.Item A novel algorithm for opaque-array concentrator photovoltaic (oa-cpv) to reduce mismatch losses(UMT.Lahore, 2021) Naveed Aftab KhanThe renewable energy sources are taking a great part along with the conventional sources for the production of increased power.

Focusing on future vulnerability is the key feature for the achievement of Sustainable development. Government officials and policy makers face many challenges for Effective implementation of strategies to face the possible climate change affects, but the main gap lies in lack of participation of different affective communities at any level of policy-making. Therefore there is a strong need of Education on climate change and affective awareness at the governmental and local levels that will help us for Building the capacity for researchers policy makers and local communities. Therefore according to present and past circumstances effective measures should be needed to address climate change phenomena in Pakistan. It is essential that the government strongly recognize potential future climate risks and protect the environment.Item Advance wireless power transfer system(UMT Lahore, 2022-05) Sadaqat Ali; Shoaib ZafarThe transfer of power energy from source to load for a distance without any conducting wire or cables is called Wireless Power Transmission.

The project involves integrating key components such as a Raspberry Pi camera (5-megapixel), Lidar sensor, 5-V encoder motors (x2), caster wheel, chassis, 40-A BMS with a 36A battery pack, and an ESP module. The progress report details the team's journey in configuring the Raspberry Pi and selecting an appropriate operating system. Initially, Raspbian was chosen, but its effectiveness proved suboptimal. After an extensive review of literature, the team opted for Ubuntu 23.10, the latest version available. However, challenges arose as ROS packets necessary for operation were not yet released for this version. Consequently, the team shifted to Ubuntu 22.04, which supported ROS 2, providing a more feasible solution. Despite its complexity, the operating system was adopted for further development. Recognizing the need for a user-friendly environment, the team revisited earlier versions of Ubuntu and settled on Ubuntu 20.4 Mate. This version not only provided a friendly interface but also had pre-installed software and support for ROS 2. The Lidar sensor, a critical component, was successfully tested on the Raspberry Pi installed with Ubuntu 20.4 Mate, demonstrating optimal functionality. Hardware development involved the creation of a custom chassis with a circular design, boasting a 14-inch diameter. This chassis accommodates spaces for the placement of encoder motors and tires. Rigorous testing of the robot's movement with the integration of two encoder motors connected to an ESP module, wirelessly communicating with the Raspberry Pi, was conducted. The wireless connection aims to minimize delays by up to 50%. In summary, the team successfully navigated the challenges of selecting an appropriate operating system, tested the functionality of key components, and established a foundation for the AI-based cleaning robot. The integration of ROS 2, a user-friendly environment, and wireless communication showcases the team's commitment to creating an advanced and efficient cleaning solution.Item AI based NOMA for Heterogeneous Networks(UMT, Lahore, 2025) Syed Muhammad HamedoonAs wireless networks evolve to accommodate increasing user density, effective user clustering techniques are essential for optimizing resource allocation in Non-Orthogonal Multiple Access (NOMA) systems. Thus, as high-speed and quick data access becomes increasingly available, the need for a sophisticated and enhanced wireless network begins to emerge. NOMA-based heterogeneous networks are essential for the Internet of Things (IoT) era as they combine multiple wireless technologies and devices to enhance coverage, capacity, and user quality of service. In heterogeneous IoT networks with many users, exhaustively searching for optimal user pairs or groups becomes computationally infeasible. As user density increases, clustering becomes a combinatorial problem that demands scalable, low-complexity solutions. This research indicates various user partitioning algorithms that enhance network performance, spectral efficiency, and user fairness, particularly in dense scenarios with diverse channel conditions. We address the challenges of user clustering and power allocation in multi-carrier NOMA systems, emphasizing the importance of energy efficiency for IoT devices. A novel user clustering approach based on partial brute force search (P-BFS) is proposed, significantly reducing complexity while improving throughput. Additionally, we explore a Reconfigurable Intelligent Surface (RIS)-assisted NOMA framework that optimizes power allocation and phase shifts through advanced optimization techniques, including deep learning and reinforcement learning. RIS-assisted NOMA systems designed for IoT networks make better use of spectrum, which saves power and keeps connections between many users stable. This system differs from conventional wireless communication systems. This research uses AI-based methods to find the best balance between sum rate and energy efficiency, finding the best RIS phase shifts and power distribution. The results demonstrate substantial improvements in sum rate and energy efficiency, highlighting the potential of intelligent clustering methods for future 5G and beyond networks.
