Abstract:

In this paper, the components required for FMCW (Frequency-Modulated Continuous Wave) RADAR (Radio Detection and Ranging) system operating at 3GHz i.e. modulator circuit and video amplifier circuit are designed and tested. For this purpose, the RF (Radio Frequency) components were selected from microstrip trainer kit MST-523 of Feedback Instruments. The working of each component is analyzed through VNA (Vector Network Analyzer) and spectrum analyzer. The patch antennas provided in the kit were used as transmitter and receiver operating at 3 GHz. The modulator circuit is built with variable frequency and amplitude to modulate the signal from VCO (Voltage Controlled Oscillator). The triangular wave is selected for this purpose to modulate the VCO. The received signal is measured on spectrum analyzer and received power is measured at every integral multiple of wavelength to check working state of antenna and change in power. The Low pass filter circuit is also designed to filter out the higher frequencies after the mixer stage. The RADAR range is calculated based on measurement of the system.

Abstract

Education is one of the main components for the growth of a state, and there is not much research done in order to improve its quality especially in Pakistan. To improve Education quality the starting point is to boost Teaching Mechanism especially Government Schools where teacher are generally not present in class. Biometrics is not a valid system to use, as Teachers have found ways to tamper this type of attendance system. Using camera raises privacy issues as well as significant man or machine power is required to solve this problem. This paper presents a speaker recognition system applied to the problem of teacher identification in “ghost schools”. The system uses a neural speaker embedding system that maps the audio lectures to a hyperspace where teacher similarity is measured by a cosine distance. We also present a corpus of audio lectures collected from 5 different teachers of 5 different courses. The dataset can be used for the evaluation of teacher identification system and contains audio lectures both for enrollment and testing. Our proposed system achieves an accuracy of 67% on the test set of the above mentioned corpus. We have made our code and corpus publicly available for reproducible research.

Keywords:

Abstract

Human to machine collaboration is an important game changer in industries as well as in daily lives. Hand gesture recognition assists this interaction by automating the process. This collaboration is supported by proposing system which can recognize human hand gestures and perform tasks based on those gestures. This paper presents the system that uses hand gesture recognition to control machine. The machine executes programmed task according to gestures recognized. The hand gestures are recognized using vision-based approach. The defined gestures are static and carried out by bare hands. The recognition of the system involves hand segmentation, feature extraction, and classification. The hand is segmented using bounding box in webcam preview, and features are extracted by determining signature of hand and histogram of signature. The classification process uses supervised feed forward neural network system to train some samples of different gestures. Once gesture is recognized, the programmed tasks start to execute. The proposed system has found to have an average accuracy of 92.6% for the classification of gestures.

Abstract

In this paper proper BW (Bandwidth) utilization is predicted using policy making decisions by using MikroTik router. Future network demands, high BW as number of devices are increasing day by day and to ensure this suitable network mechanism is needed with the help of policy making scenario. Implementing policies in firewall refrain the unauthorized access and BW is not being efficiently utilized. The results suggest that MikroTik router provides built-in firewall that is not only user-friendly in policy making but also provide QoS (Quality of Service) and makes an efficient utilization of BW resources. Policy based routing facilitates proper network management. Through policy application, network BW can be used appropriately, misuse of BW can be prevented which in turn can enhance QoS.

Abstract

In our proposed work, we are making our RAM to behave energy efficient by reducing the overall power usage by implementing it on FPGA. LVCMOS15 and LVCMOS25 have been used to observe the power reduction , which includes clock power ,logic power, signal power, i/o power, leakage power and Total power. Power reduction of about 61.4% is seen at the capacitance of 500pF by testing the RAM on LVCMOS25 and then in LVCMOS15. Also the leakage power is comparatively much lower at -33 degree Celsius with the capacitance load of 1000pF in LVCMOS25. The FPGA is tested on different temperatures including standard room temperature of 25 degree celsius, -33 degree and 48.9 degree celsius which is environmentally extreme temperature. The results are obtained by using Xilinx ISE 14.7 simulator with verilog hardware description language.

Abstract

In order to produce the quality product, assessment is made during and at the end of Software development process to check whether software is error free and to ensure whether specified requirements of the Software are met. This practice is called Software Testing. In order to cope time and resource constraints of this modern era, now a day new way of testing called automated testing is working against manual testing. In automated testing, pre-scripted tests are executed by software tool. A software tool is used to test or check software execution. Actions are pre-recorded and predefined then playback is performed through an automated testing tool, comparison of the results with the expected behavior is made and the success or failure is reported. There exists different mode of testing like unit testing, integration testing and functional testing and each one works in different perspective. Not all types of testing can be automated but a few can be. In this paper various types of testing that can be automated are discussed and how they work in different scenario. The way in which different automated testing tools perform these testing are discussed in this paper.

Keywords:

Abstract:

The objective of this research is to securely authenticate online registration of minors in the Nominee Register as a contribution to reducing the social gap in early childhood, considering that the information provided by RENIEC is information that must have high levels of security, which however should not be an obstacle to access from any place more distant places where the Government should have a presence, in this sense the OWASP (Open Web Application Security Project), open project, which is referenced by many standards of security, as a result of this implementation it was possible to securely authenticate online registration, significantly reducing vulnerabilities in all application phases, which has enabled strategic alliances with MEF and MINSA to bring technology safely to the different parts of Peru where there was little presence of the State which has allowed in the Nominal Register with the registration of children from early childhood to reduce the social gap in relation to inclusion.

Abstract:

Cybersecurity is a fundamental aspect of networks, computers, software, and data. The objective is to establish a Digital Threat Detection Model to mitigate cybersecurity risks in organizations by evaluating the influence of cybersecurity infrastructure on the global cybersecurity index. Without sufficient security, these assets are vulnerable to malicious threats (Xiong & Lagerström, 2019). The technological platforms located in the data centers of the organization itself or through service providers locally or in the cloud make available communications services, databases, application servers, and managed security services, among others. Multiple times we find that the published services are compromised by different types of digital threat that compromises the operational continuity of the organization or even its reputation. Digital services must be permanently attended even more if we have users who permanently consult the services offered on the platforms. Every service published on the Internet is always attacked by different forms or digital variants that violate or paralyze the applications that serve the public. In this sense, it is important to understand ways and ways to identify a digital threat; the criteria used to differentiate correct traffic from another that violates or intends to violate our platforms, as well as knowing how our digital services are organized, the technological infrastructure, both network architecture, and security.

Abstract:

Using electromagnetic induction, the electromagnetic brake slowly keeping slow the moving vehicle under which it will produce resistance. The Friction brakes create a pressure on to the two separate objects to reduce the vehicle speed in a Controlled mode. The magnet current turns in the form of plate heat which definitely lowers the kinetic energy. In this magnetic type of braking device, as the driver applies force on the brake pedal, a pulsating D.C. current is sent to the power pack. As per the driver’s requirement a proportionate torque is produced to decelerate the vehicle. In oil braking or air braking systems even a small leakage can result in complete brake failure and cause accidents In previous braking system we use oil which is a natural element and it has many other usages so if we exchange our hydraulic braking system with electromagnetic braking system so it may help us in economic growth and it is a clean and affordable energy.

Abstract:

Since the nature of mathematical model of an aircraft is extremely nonlinear and controlling the state variables have always been highly challenging tasks for the researchers, therefore, this paper presents an ANN (Artificial Neural Network) based control architecture to control the longitudinal dynamics of an aircraft by controlling the longitudinal motion of the aircraft. The proposed controller serves as an altitude-hold autopilot system which holds the aircraft at a desired altitude as assistance to the pilot. Using sigmoid activation function with multilayer network and back-propagation supervised learning; the NN (Neural Network) plant model is trained offline. The control algorithm is based on NN model predictive control architecture where the controller first predicts the future plant behavior for the given range of control inputs using NN plant model and then using optimization algorithm a set of potential control inputs are computed to optimize the future plant responses. The proposed model is tested for 500 and 1000 ft step inputs and a pulse input ranging from 0-1000 ft. The simulation results show that the model is working under altitude-hold autopilot mode smoothly without any overshoot and steady-state error.

Abstract:

In this paper, we have studied and simulated the general synchronization of control problems for both multiple inputs and multiple outputs. We have also addressed the nonlinear parameterizable uncertainties and get our results in asymptomatic convergence. We have proposed a new global identifier and get better results than previous research mentioned in literature. We have simulated the robot synchronization with our proposed period estimator. Our proposed global estimator is giving better results than the local period estimator.
