Performing Template Matching Process for RLNS Based System in Binary Logic

This research work is the implementation of cross correlation operation that is used in template matching process for image or object detection. Digital image processing is used in various areas such as identification of natural resources, medical diagnosing procedures, satellite pictography etc. An image is a collection of minute information called as pixels. All manipulation operation in an image is done in these pixel values that makes image processing techniques more complicated. The design of image processing hardware demands more power dissipation and area. Residue Number System (RNS) based system is applied for image processing applications, which has additional advantage of encryption in data processing. As logarithmic number system reduces multiplication process to mere addition, template matching process is proposed in this work for Residue Logarithmic Number System (RLNS) based system. In this paper the methodology for performing template matching process is designed and compared with binary and ternary logic based existing design structures and validation for the optimum design technique in terms of area consumed, Total Power dissipation and delay is proposed.

Study on Finite-time Fault-tolerant Control for a Robot Manipulator Based on Synchronous Terminal Sliding Mode Control

Two finite-time active fault-tolerant controllers for a robot manipulator are proposed in this study, which include synchronous terminal sliding mode control and an extended state observer. To estimate aggregated uncertainties, disturbances, and faults, an extended state observer is used first. The estimation data is utilised to compensate the controller that will be created in the next stage. Based on a novel finite-time synchronisation error and coupling position error, we provide an active fault-tolerant control with finite-time synchronous terminal sliding mode control. We also show an active fault-tolerant control system that doesn’t rely on coupling position error. The position error at each joint can simultaneously approach zero and equality when applying synchronisation control, which may lessen the picking phenomena associated with the active fault-tolerant controller scheme. Finally, simulation and experimental results for a three-degree-of-freedom robot manipulator show that the two proposed active fault-tolerant controllers are effective.

An Investigation on the Takeoff Performance of a Light Amphibious Airplane

The findings of a performance evaluation of a light amphibious aircraft during takeoff from the water’s surface are presented in this article. The plane is part of a bi-winged light amphibious aeroplane series developed in Thailand. A short takeoff and landing (STOL) amphibious aircraft is the goal of the concept design. A mathematical model that collaborates with several complex components is demonstrated and solved using MATLAB@. The aircraft’s water-drag resistance is estimated using NASA technical data for standard seaplane hulls, which increases the model’s accuracy during takeoff. The seaplane can take off from calm water in 26 seconds at 54 KCAS and a distance of around 890 feet with an AOA of 10 degrees, according to the simulation.

New Approach in Cryptography Using RC4 Protocol

In cryptography, the RC4 protocol is the most widely used. The goal of this project is to investigate the efficient design of the RC4 stream cypher and to propose an efficient cypher architecture. The loop unrolling and pipeline concepts were used to generate two RC4 key stream bytes every clock cycle. The design is compared to prior weeks’ designs to see how many cycles are needed to finish the individual KSA and PRGA modules, as well as the RC4 Stream Cipher as a whole. The XILINX 13.2 on Vertex ML605 Evaluation FPGA Board was used to create the design.

Study on Infrasound Propagation of Finite Amplitude Wave in the Big Size Horn

This study aims to determine the coordinate of the horn’s axial section at which the amplitude reaches its highest value, as well as variations in the acoustic pressure amplitude of the second harmonic in the horn during excitation in the horn throat of the finite amplitude wave. The laws of growth and decrease of the second harmonic during stimulation of the finite amplitude wave in the air-horn are analysed using analytical equations. It is calculated the distance at which the second harmonic propagating via the air-horn reaches its maximum. Air-horns of various shapes are subjected to a comparative investigation. All calculations were done assuming a horn with a length of 10 metres and a diameter of 4 metres at the outlet section. The acoustic signal in such a mouthpiece has a resonance frequency of 20 Hz.

Techno-Economic Analysis of Retrofitted Electric Coaster Introduction in University Campus

Green transportation focuses on resource economy and effectiveness, which results in a lower carbon footprint and a healthier environment for the country by reducing greenhouse gas emissions. The final solution may be promising new technology, but innovation will only happen if society plays a key role in the development of electric vehicles that reduce carbon emissions. Understanding how markets work to save fuel is essential for designing effective and cheap policies that enable the development of low-carbon technologies in line with political objectives. The purpose of this study is to build a 14-seat all-electric mini-coaster by retrofitting a diesel Mercedes-Benz Van with a 15-kWh lithium-iron-phosphate battery (LiFePO4). An AC induction motor with a max power of 60 kW and torque of 150 Nm drives the coaster. As an auxiliary battery, a 3.44 kWh lithium battery is used to power the battery cooling system and the passenger compartment cooling system. The coaster can travel 40 kilometres on a single fully charged battery. Depending on Malaysian fuel rates, the coaster’s power consumption is 340 Wh/km [cost USD 0.025 (RM0.12) per kilometre]. When powered by a battery, the coaster’s real operating costs are RM144 per month, and RM600 per month when powered by an internal combustion engine. As a result, both the International Islamic University of Malaysia (IIUM) and the environment gain from the cost-effective electric mini-coater.

Detection of Copy Move Forgery Using a Hybrid Algorithm

Image forgery detection in terms of copy-move detection has become a hot topic among scholars in recent years. This paper provides a system that combines saliency detection and local binary pattern-based forgery detection for real-time images. Saliency detection is used in the preliminary phase to identify the forged component. To certify the integrity of the original image, this forgery detection approach can be used in medical, forensics, and media. It connects the modified portion’s territory to the surrounding (global) area, securing the modified portion’s territory. Local Binary Pattern characteristics are then used to detect or capture the specific pixels/regions for the tampered portions. This hybrid approach retains the advantages of both the saliency map and the Local Binary Pattern, particularly in terms of scaling and rotation, while also having a higher detection rate than existing methods. The proposed method, in addition to the existing forgery detection result, leverages depth map information to correctly identify the faked region. Bits per pixel are used to determine the severity of the modified section. The proposed technology is unusual in that it can detect altered areas of digital photos in real time. In a state-of-the-art comparison, the proposed method is proven to be significantly superior than existing methods.

Implementation of Fault-Tolerant Control for a Robot Manipulator Based on Synchronous Sliding Mode Control: An Advanced Study

In this paper, a synchronous sliding mode-based active fault-tolerant control for a robot manipulator is developed. The joint errors tend to equalise and approach zero as the synchronisation errors approach zero. As a result, for a fault-tolerant controller, the synchronisation mechanism is intrinsically effective. The following implementation is provided to demonstrate such a system. To begin, an estimator with an extended state observer was created to estimate uncertainties/disturbances as well as faults/failures. In the controller, the estimator signal was employed for an online compensator. A fault-tolerant controller was suggested that used a synchronous sliding mode method and an estimator. Lyapunov theory was used to determine the system’s stability. Finally, fault tolerant control was compared to conventional sliding mode control in a three-degree-of-freedom robot manipulator. The effectiveness of the proposed active fault-tolerant control with synchronous sliding model technique is demonstrated in this comparison.

Complexity Estimation of Automata Models with Use the Discrete RIV-functions

The depiction of laws of system functioning is used in methods for deciding control problems, synthesis, and analysis of discrete determined dynamic systems (automatons). The phase trajectories, which define system behaviour, are systematised and shown in phase images. The wide range of phase pictures created by V. A. Tverdokhlebov is due to their uniform form – symbolical and numerical graphs in which points correspond to geometrical curves. The related automaton mapping will be translated to a numerical graph with points situated on geometrical curves when the automaton is represented by a geometrical image. V. A. Tverdokhlebov’s method of extracting laws of functioning of the automaton of sequence of the second coordinates of points, accurate within number of input signals, from a geometrical image allows research of laws of functioning of automatons to be reduced to research of properties of numerical sequences. On the basis of geometrical representations of laws and the usage of discrete riv-functions, this study proposes the evaluation of complexity of rules of functioning of discrete determined dynamic systems (automatons). Is responsible for analysing about 10 million discrete riv-functions. The least and greatest number of states at the minimal automaton from the set of automatons described by riv-function are used as complexity indicators.
