Item Orientation independent display(UMT Lahore, 2011-07-28) Syed All Arslan; Syed Muhammad Taqi; Sheikh Haroon SaeedIn this project, we have developed an orientation-independent 25×5 LED array display. The array is capable of displaying alphanumeric characters in eight randomly selected orientations: 0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315°. To control orientation independence, an accelerometer was a good choice, but we substituted it with a self-made device because it was cost-effective. This report contains comparisons between different alternatives, a detailed description of each component, algorithms, and assembly language code.Item Dual band mobile jammer for GSM 900 MHZ &GSM 1800 MHz(UMT Lahore, 2011-03-24) Waqas Ahmed; M. Omer; Hafiz Hassan Latif; Asim AbdullahThis report represents the design and implementation of a device that transmits on the same radio frequencies as a cell phone, disrupting the communication between the phone and the cell-phone base station in the tower. Jamming devices overpower the cell phone by transmitting a signal on the same frequency as the cell phone and at a high enough power that the two signals collide and cancel each other out. Cell phones are designed to add power if they experience low-level interference, so the jammer must recognize and match the power increase from the phone. Some jammers block only one of the frequencies used by cell phones, while sophisticated jammers can block several types of networks at once to head off dual-mode or tri-mode phones that automatically switch among different network types to find an open signal. Communication jamming devices were first developed and used by the military. Nowadays, mobile jammer devices are becoming civilian products rather than electronic warfare devices. With the increasing number of mobile phone users, the need to disable mobile phones in specific places where ringing would be disruptive has increased. These places include places of worship, university lecture rooms, libraries, concert halls, meeting rooms, and other places where silence is appreciated.Item Intelligent security system based on wireless sensor network.(UMT Lahore, 2011-08-12) Aneeb Sehar Manzoor; Abdul Jabbar Hassan; Sarakh MahmoodThis project is designed to provide security along with management to the user. It provides security by allowing entry through a code-based system, and the door can also be unlocked remotely through GSM. It offers flexibility to change the password remotely or through a keypad mounted on the door. Additionally, a camera enhances security by providing visual monitoring. The user can rotate the camera horizontally and vertically from anywhere without a physical connection. To further enhance security, the system informs the user if an incorrect code is entered three consecutive times. It also allows the user to manage certain appliances, such as temperature-controlling devices, and transmits temperature readings to the user on demand through GSM.Item PLC based automation of carding section(UMT Lahore, 2011-05-31) Iqbal Hussain; Waqas Asghar; M. Ghayyas Khan; Muhammad Sajid KhanThe use of control systems such as computers to control industrial machinery and processes, replacing human operators, is called automation. Automation greatly reduces the need for human sensory and mental requirements and provides control without human intervention. It provides facilities such as moving heavier loads accurately, precise positioning, moving very fast or very slowly, reduced manual handling, and improved efficiency. We have used a programmable logic controller (PLC) for the automation of a carding machine. A programmable logic controller is a device that was invented to replace the necessary sequential relay circuits for machine control. It works by monitoring its inputs and, depending on their state, turning its outputs on or off. The user enters a program, usually via software, that produces the desired results. A programmable logic controller is a user-friendly, microprocessor-based specialized computer that carries out control functions of many types and levels of complexity. Its purpose is to monitor crucial process parameters and adjust process operations accordingly. A carding machine is used for the alignment of threads, and thus uniform sliver is produced. A by-product in the form of garbage is also obtained. Different types of carding machines are available in the market, but in past years many carding machines were manually operated or lacked effective control mechanisms for garbage collection. These machines were time-consuming, had low production rates, high costs, and required increased manpower. To overcome these problems, the carding machine needs to be automated. Automation of the carding machine requires control of many digital inputs and outputs.Item Energy saving system(UMT Lahore, 2011-08-12) Omer Farooq Minhas; Shahid Farooq; Waqas Ali; Imtiaz AliAs we all know, our homeland Pakistan is suffering from the worst energy crisis in history. Every day, we are running out of fuels like petrol, diesel, gasoline, and natural gas. So, electricity produced by these sources is also very expensive. The ideal source for Pakistan is solar energy. Due to this reason, we chose to work on this project, which can help solve these problems. To make this a little better, our project implements a smart algorithm to power a load using solar energy, batteries, or WAPDA. The goal of this project is to power a load with minimum power drawn from WAPDA. To develop this project, we needed to monitor the voltage and current flow from each of the sources (solar, batteries, and WAPDA) as well as the load. We implemented these current and voltage monitors. The next step was to design an algorithm that determines which source should power the load and when the battery should be charged. The final step was to send the data to the PIC so that it could be analyzed.Item Wireless sensors (applications on distribution line)(UMT Lahore, 2011-03-25) M. Ishaq Khakhi; Ihsan Raza; Ahmed Bilal; M. Farhan MunawarThe wireless sensor concept revolves around the sensor node or “mote,” which essentially consists of a sensor, microcomputer, power source, and transceiver that form the input stage of any system. It detects physical parameters (temperature, pressure, proximity, vibration, sound, electromagnetic, etc.), converts them into quantifiable data, and sends the data to a host for processing. The information is then collected by the system along with data from all other sensors for a specific control or monitoring task. Wireless sensors gather information about the physical environment and connect it to systems and networks to provide monitoring, automation, and control for many varied applications. The uses of wireless sensor networks are almost unlimited, with many industries and applications having specific technology requirements such as reliability, permanence, battery life, range, frequencies, and sensor use. These systems can take the form of security systems, monitoring equipment, and machinery in factories, monitoring forces. Current and future design goals in the aerospace sensors and transducers field call for the development of new sensing devices that require less electrical power, occupy less space, and weigh less. Self-calibration, self-health assessment, processing of raw data at the sensor level, and alternate data transmission methods are desired to provide users with information in a more efficient way. The Instrumentation Branch of the NASA Spaceport Engineering and Technology Directorate at Kennedy Space Center, along with Dynacs Inc., was tasked with investigating new ways to design and develop transducers with these characteristics. As part of the initial efforts to acquire the skills and new technologies for such pursuits, the Transducers Development Group began investigating the use of wireless communications at the sensor level.Item Ultrasonic based distrance measurement (UBDM)(UMT Lahore, 2011-04-18) Muhammad Usman Khan; Ali Khalid Pervez; Fawad Ajmal; Aliya SaeedThe demand for advanced features in cars is ever increasing day by day. A significant portion of people around the world own cars or are daily drivers. Among these drivers, it is not entirely untrue to assume that parallel parking or rearward parking is one of the most cumbersome parts of their driving experience. It takes years of driving experience and rigorous practice to avoid a fender bender or an ugly scratch across the bumper. Most of us like to take advantage of advanced car electronics and technologies to make our lives a little easier and to avoid common accidents during parking. Hence, we decided to design and build an ultrasonic distance-based measurement system that helps the driver sense how far their car is from a wall or an object and provides visual and audible warnings using LEDs and a speaker, respectively.Item Speech recognition system(UMT Lahore, 2011-06-01) Salman Ahmad; Fahad Mukhtar; Muhammad Tahir KhanItem Bandwidth and subscriber estimation in uplink and downlink for multi-class single-cell users in mobile WiMAX(UMT Lahore, 2011-11) Umair ShahidThe fundamentals required for steady growth of broadband wireless remain constant. According to Ericsson’s official predictions, the global market of broadband connectivity will be around 320 million users by the end of this decade. The issues related to increased deployment of WiMAX give rise to challenges related to QoS and scalability. A unique methodology has been adopted to maximize the number of users per sector for multi-traffic users, which include both residential class as well as business class users. The approach makes use of useful bandwidth estimations and implements an algorithm to provide a solution to QoS by restricting the number of users according to bandwidth allocated in both uplink and downlink directions. A modernized methodology to compute the system’s actual throughput and a traffic model for diverse application users is proposed, with a step-by-step depiction to derive an algorithm to determine the maximum number of subscribers that each specific mobile WiMAX sector may support. The results are shown using MATLAB, which takes various system parameters along with service class parameters and presents the results in terms of the maximum number of users supported, along with uplink and downlink bandwidth demanded and capacity available. The presented methodology would help operators planning to implement a wide-coverage network in a city. Using this methodology, service providers will be able to estimate the exact number of base stations and, hence, the network investment and profitability.Item Energy ramp(UMT Lahore, 2011) Faisal Iqbal; Mohsin Sharif; Azeem TahirIn the present scenario, power has become a major need for human life. Due to the day-to-day increase in population and the reduction of conventional sources, it has become necessary to depend on non-conventional sources for power generation. While moving, vehicles possess some kinetic energy, which is usually wasted. This kinetic energy can be utilized to produce power by using a special arrangement called an “energy ramp.” The kinetic energy of moving vehicles can be converted into mechanical energy of the shaft through a rack and pinion mechanism. This shaft is connected to an electric dynamo, which produces electrical energy proportional to traffic density. All this mechanism can be housed under the ramp (a slope built to connect two places at different levels). The generated power can be used for general purposes such as streetlights and traffic signals. The electrical output can be improved by arranging energy ramps in series; this generated power can be amplified and stored using different electrical devices. The maintenance cost of the ramp is almost negligible. By adopting this arrangement, future power demands can be satisfied to some extent.Item Energy efficient conference hall(UMT Lahore, 2011-08-12) Amber Naz; Iram Qamar; Asfa JavedThe project energy-efficient conference hall mainly emphasizes the efficient use of energy resources by using different automation functions. In this controller-based design, different types of sensors are used to make the hall automatic and intelligent. The arrival of the first person is detected at the door of the hall, and the main light is turned on automatically. Individual lights are controlled with respect to the number of persons and their positions. Moreover, the AC or heater is turned on or off if the temperature exceeds or falls below specific limits. The project also involves a display outside for continuously updating the number of people present inside the room to avoid congestion. IR sensors are used for object detection to make the project more cost-effective.Item Stereoscopic Video Surveillance System(UMT Lahore, 2011-08-12) Rehan Ahmad Baig; Hassaan Ahmed; Ahmed FurqanThe aim of the project is to design and implement a stereo vision system using two simple web cameras to simulate the stereopsis of human vision, which allows for accurate depth and distance perception from a pair of two-dimensional images, and a pair of small servo motors for pitch and yaw. For the purpose of this project, we have two standard webcams and two servo motors mounted on a mechanical platform. Motor control is performed via a PIC microcontroller, which itself is controlled via a serial interface with MATLAB. Image processing, tracking, and the implementation of stereo vision will also be done in MATLAB, where existing algorithms will be optimized and new ones utilized. The focus here will be on reducing computation time for the stereo image pairs, since image processing is a CPU-intensive task and can take a while on the processors found in today’s laptops and PCs. The true scope of this project and its many uses is better understood by observing the burgeoning field of computer and robot vision, which boasts technologies such as early obstacle warning systems in vehicles and intelligent security systems, both of which utilize stereo vision to make detailed depth maps. The now-defunct Mars Rover is a pioneering work in this field and is still heralded as one of NASA’s greatest achievements to date. This BS project attempts to mimic as much of these cutting-edge technologies as possible.Item Location updating system via Google Mapping(UMT Lahore, 2011-03-08) Shakaib Ishaq; Usman Amjad; Zeeshan AhmadIn this modern, fast-moving, and insecure world, it has become a basic necessity to be aware of safety. Maximum risks occur in situations where an employee travels for money transactions. The company to which the employee belongs should also be aware if there is any problem. What if the person traveling could be tracked and secured in case of an emergency? This is where a system that functions as both a tracking and security solution comes in—the VMSS. This system addresses both speed and security. The VMSS (Vehicle Monitoring and Security System) is a GPS-based vehicle tracking system that is also used for security applications. The project is based on two main underlying concepts: GPS (Global Positioning System) and GSM (Global System for Mobile Communication). The primary application of this system is to track the vehicle to which the GPS is connected, provide information about its position whenever required, and ensure the security of each person traveling in the vehicle. This is achieved with the help of GPS satellites and a GPS module attached to the vehicle that needs to be tracked. The GPS antenna present in the GPS module receives information from the GPS satellites in NMEA (National Marine Electronics Association) format, which reveals the position details. The information obtained from the GPS antenna is then sent to the base station, where it is decoded. For this purpose, a GSM module with an antenna is used. Thus, the base station receives complete data about the vehicle.Item Automated mobile controlled robot(UMT Lahore, 2011-08-12) Zain Hussain; Mohsin Ali Arif; Waqas MalikThis project report is aimed to describe the complete picture of constructing a universal range robot using DTMF. Long range has always been the most challenging aspect in home navigation for mobile robot. A specially configured robot is needed whenever a robot wants to tackle this challenging problem. This project mainly deals with the design and development of a universal range mobile robot. It has the ability to operate throug a large distance such as from one city to another. There were two major parts in design and fabrication of the robot and they are mechanical and electronic. In the mechanical portion, base body, gears holder, wheels, fitting of DC geared motors, free wheel, pulley and belt mechanism were designed and constructed. Two DC geared motors were used to drive the robot. PIC microcontroller is used as main processing unit of the robot and the controller communicates with the DTMF decoder and motor driver circuit for the purpose of navigation as the robot has to move in all directions.Item Green House Effect(UMT Lahore, 2011-07) Ali Nawaz; Ali Mehmood MalhiItem Surveillance and spying using GSM based automobile device(UMT Lahore, 2011-08-12) Mian Muhammad Junaid Alam; Saqib Naeem; Waqar-ul-HaqCreativity plays a vital role in development of any product, process or a system. Expansion of an idea is one of the basic steps in this regard. In this project, we present controlling of a car using DTMF technique. The car is controlled by a mobile phone that makes call to the other mobile phone attached to the car. In the course of the call, if any button is pressed, tone corresponding to the button pressed is decoded at the other end of the call depending upon the generated signal. This tone is called dual tone multi frequency tone (DTMF). Using DTMF code, direction of motion of the car can be controlled by mobile phone. Car has a wireless camera that transmits an actual video at the operator’s monitor. Based on the received video, the corresponding signals from the mobile phone keypad can be passed from the mobile phone which is connected with the transmitter side.Item Wind turbine power generation system(UMT Lahore, 2011-08-12) M Rashid Ashraf; Hassan Mahmood; Abdul BasitThe goal of this project is to design and implement a wind turbine system that charge up the DC battery with capabilities of charge controller, a digital voltmeter to monitor battery voltages, and an inverter module to convert DC into AC. Some of the specifications that we sought to achieve in our project is to design a mechanical system for turbine generator to produce 12V or above in a wind speed of about 12 to 13 mph, a charge controller based on voltage level sensing, a 31/2 digit digital voltmeter with 0.1% accuracy, and a 100 watt inverter module. The complete system will consist of wind turbine mounting assembly and three processing circuits: charge controller, digital voltmeter, and an inverter module. By implementing this system, we are showing how different devices are integrated together to form a complete active alternative energy system.Item Design and Implementation of Wireless Bridge Monitoring System(UMT Lahore, 2011-08-12) Muhammad Imran; Usman Zulquernain; Umer Fareed ChThe sudden collapses of bridges and large structures raised general questions regarding the inspection of civil engineering structures. Our opinion is that a combined approach is necessary to ensure the safety of structures and to improve the sustainability of large structures to avoid sudden collapses. This combined approach is presented in the following. The main purpose of monitoring civil structures is to support regular visual examinations or inspections based on non-destructive testing techniques. A monitoring technique is presented to consist of a wireless sensor network using different types of sensors e.g. load cell. Sensor networks can be used to monitor a certain region of a structure providing data about different physical measures. Some properties to be measured e.g. load and temperature on the structure. A wireless network propagates the sensor data towards a common base station where further analysis is performed.Item RFID Based Security System(UMT Lahore, 2011-08-12) Mohammed Amin; Usama YounasRadio frequency identification (RFID) technology is a non-contact, non-line of sight based technology. The main object of the RFID technology is the verification of an object or person to which a tag is attached too. Each tag consists of a unique code which differentiates between different objects and person. It is the only technique that is practical in environmentally challenging conditions where other optical or contact based technologies would be useless. Essentially an RFID is a portable database and a wireless extension of information systems. This project consists of such a security system which allows the passage of authorized cards only. All unauthorized cards will be detected and will cause the RFID system to generate a SMS to the head of security.Item Automatic toll tax control system for Motorway using image processing(UMT Lahore, 2011-12-08) Muhammad Javaid Iqbal; Umer AshrafAutomatic toll tax control system for motorway is a MATLAB program which is used for automatic vehicle data entering such as number plate, toll tax, vehicle entering time and date. First snapshot of the vehicle would be taken at entering gate, then system will detect the number plate from the whole picture and will extract the license number from the number plate. After extracting number it will send the number to the sever to enter in database. Database will contain the following entries: toll tax, entering and exit booth ID, car entering time and date, and number plate in database. At exit side the same procedure will repeat like snapshot of vehicle, number plate extraction and send to the sever to update entry in database. Here server will update exit time and will calculate the toll tax for the vehicle, and it will send the calculated tax to the exit side. So our aim is to develop an effective, efficient and standardized automatic toll tax control system for motorway using image processing for low cost using MATLAB.
