Item GSM Based Monitoring And Control Of Water Pump System(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2013) Ali Yusaf Khan , Saim-U-Dher , Rizwan Jaffar , She; SP09-BTE-014 , SP09-BTE-050 , SP09-BTE-068 , SP09-BTE-074; Miss Arsla KhanIn this project, we are developing a system that will provide and monitor the functioning parameters of a remotely placed water pump. Sometimes, the user is not present on the actual location of the system. For that, he will have to connect wirelessly with the system. The project is designed to take into account values of temperature and voltage of pump. It also gives the opportunity of controlling the flow of water pumping through the pump. The system will work using GSM technology in which a mobile user will send an SMS to the water pump system and request certain values. The user may also send commands to change the flow of water.Item Efficient tracking of subatomic particles in the presence of multiple scattering in muon ionization cooling experiment(comsats university islamabad lahore campus, 2022) Tehreem Tariq; FA19-REE-005; Dr. Imran Ghous; LHR TP 7888Muon Ionization Cooling Experiment (MICE) is an experiment of high-energy physics. It is used to cool muon beams using ionization cooling. The target of MICE is to obtain a muon beam with reduced phase space. Particle detection inside the cooling chamber is important to gain insight into the process. It is a challenging task because millions of particles pass through the particle detectors, and it becomes further complicated due to the presence of multiple scattering. When particles pass through the detectors, multiple scattering occurs. Multiple scattering distorts the trajectories of particles. As a result, the position and momentum of particles change, and the non-linearity of the system increases. Track fitting algorithms are used for particle tracking in MICE. In the past, Kalman Filters (KFs) and Particle Filters (PFs) and their adaptations have been used for non-linear tracking in MICE experiments in the absence of multiple scattering. PF has been widely used in non-linear systems, but it was not used for non-linear non-Gaussian multiple scattering in MICE. Ignoring the multiple scattering or taking it as a Gaussian approximation, PF outperformed Unscented Kalman Filter (UKF) and Unscented Particle Filter (UPF) when compared in terms of accuracy but was more computationally complex than UKF. UPF was more computationally complex than PF but solved the problem of particle degeneracy and shifted the particles to the regions of high likelihood. In this thesis, non-linear non-Gaussian multiple scattering is studied by using the filters, which perform well for non-linear non-Gaussian systems because multiple scattering is non-Gaussian in nature, whereas most of the filtering techniques are designed for Gaussian approximations. The effect of multiple scattering, in its true form, on performance the of MICE has not been studied before. This will be the contribution of this research. In this research, UKF, PF, and UPF are used to study the behavior of the system in the presence of non-Gaussian multiple scattering and to compare their effectiveness in terms of accuracy and computational complexity.Item Performance Analysis Of Ant Colony Optimization(Publisher COMSATS University Islambad Lahore Campus, 2020) Syed Wajahat Raza Bukhari,; SP19-REE-006; Dr. Yaqoob Javed, Assistant Profesor [Supervisor]; LHR TP 7472From the past two decades the swift advancement in the field of power electronics, especially in photovoltaic (PV) power generation has led to the ever-increasing demand of highly efficient and robust power supplies. Thus Research & Development in this field has led to the use Switching Mode Power Supplies (SMPs). Thus, they provide minimal power losses which reduces the heat stresses on the system and enhances the power produced. Now the performance of power converter mainly depends on the control algorithm and the type of converter used. Each converter behaves differently under different shading conditions through the day. During the partial shading condition, we require such converter equipped with a fast-converging control algorithm that it senses the partial shading condition and tracks the maximum power point. Therefore, this research thesis represents an advance MPPT technique of Ant Colony Algorithm to optimize the maximum power tracked in minimum time. For this purpose, an ACO algorithm with optimal colony size was developed and tested on two advanced DC-DC converters for performance analysis which are Boost and SEPIC. Both converters were tested on three different conditions of solar irradiation to simulate a day response of converter. As each PV module daily receives different solar irradiation due to weather and shading conditions. Therefore, each converter with ACO was tested for Uniform Shading Condition, Partial Shading Condition and Extreme Partial Shading Conditions. Additionally, this thesis also represents a comparative performance analysis of Particle Swarm Optimization Technique and Perturb and Observe Technique on the same converters under same shading conditions. In the end a comprehensive conclusion based upon the results of simulation is made.Item To Design Hybrid AC-DC Droop Controller For Load(Publisher COMSATS University Islambad Lahore Campus, 2019) Ahsan Nadeem,; FA15-REE-001; Dr. Mirza Tariq Hamayun, Assistant Profesor [Supervisor]; LHR TP 6849In the 21st century there are several issues with the current electrical power system, such as production of green house gasses and losses (transmission line and conversion losses) that reduced the efficiency of power system. Currently, DC load demand of applications, such as telecom exchange networking system and electric vehicles (EVs) are increasing. In conventional power system, these loads are connected to main grid through converters. Moreover, diesel generators based backup solutions for telecom exchanges have several disadvantages, such as non-reliable starting of generator in cold weather conditions, maintenance of the generator, and exhaustive fumes. Furthermore, in recent times the use of EVs is increasing rapidly and now work place required to have own EV fast charging docking stations; therefore, in our simulation we consider the DC load of employees EVs along with the DC load of telecom exchange. A hybrid AC-DC micro-grid based on distributed generations is proposed as a suitable solution to reduce the multiple reverse conversions within the telecom exchange. For hybrid AC-DC micro-grid, we develop a droop controlled scheme that manage the power flow between AC and DC electrical networks by enforcing the normalized value of frequency equal to the normalized value of voltage of DC micro-grid. The controller provides, need based power sharing between AC and DC grids and enhance operational reliability of the network. The hybrid AC-DC micro-grid presented in this report is an effective solution to eliminate the excessive voltage conversion problem of telecom exchanges along with an efficient fast charging system for the EVs.Item An Efficient Solar Energy Harvesting Technique(Publisher COMSATS University Islambad Lahore Campus, 2020) Muhammad Annas Hafeez,; SP17-REE-006; Dr, Muhammad Yaqoob Javeed,From last few decades, Renewable energy sources are providing core role to fulfil energy demands. The need of producing energy in electrical form from everlasting energy sources arise due to fossils fuel’s reduction (coal, petroleum, natural gas etc.). Approximately 17% demand of the world’s energy is fulfilled through these everlasting sources. Energy through solar is considered the main source of energy among others renewable energy sources because of its pollution and noise free nature. Energy through solar is widely used to produce electricity by using photovoltaic cells. The inconsistent irradiance, temperature, and unexpected behaviour of weather effects the output of photovoltaic systems, classified as partial or complex partial shading conditions. Under these circumstances, obtaining the maximum output power from the PV system becomes strenuous. This thesis proposes a population-based optimization model, Harris Hawk’s Optimization (HHO) based on the natural inspiration to harvest maximum power under partial or complex partial shading conditions. It is an intelligent strategy, inspired by the surprise pounce chasing style of Harris Hawk. The proposed technique outperforms under different weather conditions, have less computational time, fast convergence speed, and zero oscillations after reaching a power point’s maximum limit. Performance comparison of HHO is made with conventional techniques such as, perturbs and observe (PandO), Incremental conductance (Inc), Bio-inspired particle swarm optimization (PSO), Adaptive cuckoo search optimization (ACS), Hybrid and Dragonfly (DA) algorithm. HHO achieves 99.4% efficiency on average and performs very well among rest of the competing techniques. Under HHO the oscillation is compact to < 1W & the re-tracking is tremendously effective. The results indicate in Table 4.3 shows the HHO algorithm outperforms other algorithms, with reference to fast tracking, convergence time, settling time, efficiency as well as stability under different weather conditions and can attain maximum power point with negligible oscillations, under partial and complex shading.Item Health Assessment Of Human Knee Using Acoustic(Publisher COMSATS University Islambad Lahore Campus, 2023) Zeeshan Arif; SP19-REE-011; Dr, Khurram Ali, Assistant Profesor [Supervisor]Based on the analysis of 116 healthy and 116 osteoarthritic knees, this thesis details the discovery of knee Acoustic Emission (AE) as a helpful tool for the health assessment of the human knee. Knee Osteoarthritis (KOA) is a widely spread disease all over the world which arises because of damage to the joint cartilage and subchondral bone. The main factors, which increase KOA, are unhealthy lifestyle, injuries, and aging. Currently, diagnosis mainly depends on symptoms reported by patients and medical tests like X-rays and Magnetic resonance imaging (MRI). Symptoms start to appear over a years. Current diagnosis methods have some limitations and approachability issues because of the heavy machinery required to perform these tests and the cost of the test is also the main factor that this disease is not identified on time. One of the major limitations is that these tests are carried out when the body is in a static position and doctors get no visualization of the knee performance in normal functional movement. In this research, we are purposing a cost-effective method to get the status of knee health in its normal functional movement by studying the AE produced during the movement of the knee. We tried to identify the presence of OA in the knee and also tried to figure out how we can suggest the severity of the disease by using AEs. Hardware was developed with the collaboration of LUMS hardware was capable to listen to the acoustic sounds from the knee. The hardware setup includes the piezoelectric sensor, piezo film lab amplifier, and NI-DAQ USB6009. The signal is acquired from the knee joint by attaching the piezoelectric sensor with the help of double-sided tape.Item Smart Energy Harvesting (SEH) Using Physical Exerc…(Publisher COMSATS University Islambad Lahore Campus, 2017) By: M.Usama Zafar , Zeeshan Khalid; , DDP-SP13-BEE-032 , DDP-SP13-BEE-047; Mr. Hasnain Kashif, Assistant Profesor [Supervisor]The Smart Energy Harvesting using physical exercising machines which are feasible enough to harvest power seems to generate a new source of renewable energy. Biomechanical energy harvesting constitutes a clean, portable energy alternative to the fossil fuels currently being used. Biomechanical energy harvesting is a novel approach for producing energy for small devices. The energy expended in a typical workout at the gym is usually wasted in the mechanics of the equipment. This project will harness the mechanical energy of the machine and convert it to electrical energy using a generator based system. The exercise equipment will be attached to a generator. This creates a dc voltage which will be fed into a DC-DC converter and then sent to a battery where it can be stored for future use. This proposed system will help consuming our physical energy in some useful way.Item Recovery Of Hydrogen From 5500 Nm3/Hr Ammonia(Publisher COMSATS University Islambad Lahore Campus, 2014) Muhammad Abdul Qyyum; FA10-BEC-041; Asim Laeeq Khan, Assistant Profesor [Supervisor]; LHR TP 5920Every atomic element ever in the history of the universe began as a H2 atom that had undergone nuclear fusion within a star. In other words, every one of us is a byproduct of H2. It is mainly used in the synthesis of nitric acid, which is used in fertilizers and explosives. There are many processes from which we can produce NH3 including Haber process, Cryogenic process, NH3 from natural gas, Electrolysis, Partial oxidation, Adiabatic reforming, Coal gasification. In this project, we have separate H2 from NH3 purge gas using Poly Sulfone Membrane Technology. In ammonia production, hydrogen and nitrogen are reacted at high pressure to form ammonia. Since the conversion per pass is not 100%, the reactor is operated in loop mode. In the processes, a purge stream from an ammonia synthesis loop, which purge stream contains NH3, is contacted at a super atmospheric pressure with the feed side of a separation membrane which exhibits selective permeation of each of hydrogen and ammonia as compared to the permeation of each of methane and argon. A total pressure differential across the membrane is maintained to provide a driving force for the permeation of H2 and NH3 through the membrane. A H2-rich permeating gas which contains ammonia is obtained on the permeate exit side of the membrane. TItem Modeling And Implementation Of Converter Based(Publisher COMSATS University Islambad Lahore Campus, 2019) M. Hussaan Khan , M. Zahab Rashid,; FA15-BTE-036 , FA15-BTE-052; Nisma Saleem, Assistant Profesor [Supervisor]; LHR TP 5887Reliability and cost-effectiveness are the main reasons behind the extensive use of induction machines in industry. However, major drawback of Induction machine is that they draw reactive power. Several techniques were adopted in past in order to improve the performance of Induction machine. In recent years, Rectifiers and Inverters were introduced and gained a lot of attention and helped in improving the Dynamic performance and Power Factor of an Induction machines. In this project, a Converter-based circuit is designed and attached with an Induction machine in order to explore the Dynamic performance and to improve the Power Factor of machine. A model is designed in SIMULINK and its performance is judged. Then an experiment is conducted by implementing the same model on induction machine. Different parameters are observed like efficiency, Power Factor and Dynamic performance of Induction machine (which includes starting, loading, load changing, capacitor voltage, rotor current, stator current and speed). However, simulated and experimental results should showcase an agreement. Moreover, the above-implemented technique is compared with previous Power Factor improvement techniques, which were adopted in past in order to improve the performance of Induction machinesItem Environment And Feeding Control Of Poultry Farm By:(comsats university islamabad lahore campus, 2020) Abdul Basit , Muhammad Umar,; FA15-EEE-024 , FA15-EEE-022; Dr. Yaqoob Javed, Assistant Profesor; LHR TP 5866By automation we reduced a manual work. In controlled-environment house inside conditions had kept as near as possible to the bird's best requirements. In controlling systems, the user can adjust entirely to bird’s optimum requirements with the use of sensors and controller. We make it automatic so that no need to worry about the feed, water, light, humidity, temperature. Due to automation, time waste has been reduced. The feed to gain ratio is improved with exact nutrient feeding program that provided best outputs with less human efforts and also human errors. Our system provides distant excess to growers. Hence growers are able to monitor these unit using his mobile. The project promotes a flexible, inexpensive and business version which is able to perform best for tiny to medium size operations.
