Agricultural countries like Bangladesh lose large amounts of crops due to unseasonal rain, which is concerning to the country's economy. This project aims to deliver a proper shed system for saving crops or plants from unwanted rain, which is innovative, cheaper, and effective. The most important advantage of this system is that it is fully automated such as: When it rains, the shed system opens automatically, and when it stops raining, the shed system closes automatically by sensing the rain with the help of a rain sensor and the user will be notified through IoT. For IoT purposes, a Wi-Fi module is used and for this, it is possible to get notifications on phone. This project also describes the project model, testing, and hardware. This system consists of the innovative design of an umbrella system for the shed system, which opens and closes with the help of a high-torque motor and is fully automated and controlled by Arduino. This umbrella shed system is the heart of the project which will protect the crops from unwanted rain as a result people will be benefitted and the economy in the agriculture sector will rise beyond expectations.

Here a new model of single inductor employed quadratic structured multilayer boost converter circuit is developed to be implemented in high-gain renewable energy systems. The study and functioning of a photovoltaic system utilizing a hybrid dc-dc configuration as a high step-up converter along with the incorporation of the Maximum Power Point Tracking (MPPT) technique are elucidated here. The characteristics of the quadratic multi-layered converter circuit have been tuned to provide high voltage gain and efficacy (98%) with minimal ripple contamination in input current. To ensure the adaptability of the proposed circuit, a distinct performance comparison of various topologies has been executed. The proposed circuitry showed improvement across all evaluated aspects compared to other existing topologies. The performance analysis of the recommended structure has been substantiated by PSIM and MATLAB Simulink software.

A substation is the most important component of transporting or distributing electricity in any region or industry. To control and monitor the substation, different automation structures are developed in our country and around the world. The proposed system is to develop an IoT-based smart solution for monitoring and controlling the transformer in a substation. The control unit serves as the hub for all the system equipment and activities. Using an ultrasonic sensor and the DHT11, this smart solution can monitor transformer oil and temperatures. When the temperature of the transformer climbs over the specified value, the cooling fan turns on and provides sufficient air to lower the temperature. The voltage and current sensors' collected data determine whether the circuit is open or closed. This eliminates the expense at the substation by minimizing operating costs. As a result, both observational and operational effectiveness will undoubtedly improve.

This research aims to increase performance parameters of conventional CMOS based 4-bit carry look-ahead (CLA) adder. CLA adder in conventional design fully utilize static CMOS (S-CMOS) logic for which its transistor count is quite high. Moreover, due to high input impedance, its delay is also high. To enhance performance and to reduce transistor count, (1) full swing gate diffusion input (GDI) based AND gates and (2) GDI based XOR gates have been utilized rather than using S-CMOS based AND and XOR gates. According to simulation conducted using Cadence tools, the proposed CLA adder design achieved noteworthy improvements in performance compared to the fully S-CMOS based existing design.

The creation of an autonomous vehicle has two major goals: to minimize the amount of labor that must be performed manually and to provide the automobile with superior intelligence. In order to turn a standard automobile into an autonomous vehicle that can drive itself around a predetermined map (in this case, a university campus), several modifications need to be made. The outcomes of this project will also contribute to the creation of a more technologically advanced campus atmosphere. Additional responsibilities include taking control of the horn system and being in charge of the headlights while also receiving the response signal from the station. In order to guarantee that everything functions correctly, we utilized components such as the Raspberry Pi, light sensors, motors, Arduino Uno, ultrasonic sensors, buzzers, and cameras. A temporary model is built to ensure that this project is successful right from the start. The training model trains the deep learning approach using images captured by a camera in manual mode, which enables the vehicle to operate in autonomous mode using the multilayered neural network that was taught. The final prototype utilizes image processing methods to track lanes. A few image processing technologies, such as intelligent edge detection, provide autonomous movement capabilities. These algorithms were built and tested on the vehicle. The system operated without a hitch, and the data gathered was within reasonable bounds of expectations. As well as demonstrating how the autonomous system of an electric car works.

This paper presents a complete software design, development, and implementation for an automated radio telescope application. The software design consists of front-end, back-end, mobile application, control room, and virtual reality components. This software has been developed incrementally for the last four years. Each development was tested with simulated data first then with the hardware and/or with users to confirm the robustness. The software was tested on the actual physical radio telescope using an inertial testing frame with a 363 kg load. The test results confirmed that the control room software successfully communicated with the sensor network, control room hardware, mobile application, and back-end to run the telescope in an automated mode. The mobile application interacted with the control room application to control the telescope remotely. A virtual reality simulation was effective in understanding the telescope operation and demonstrating its capabilities.

Combined Economic Emission Dispatch (CEED) is resolved by combining Success History Moth Flow Optimization (SHMFO) and valve-point loading of thermal generators. This SHMFO the valve-point loading problem is a multi-objective nonlinear optimization problem including generator capacity limits and power balance. The valve-point loading causes oscillations in the input-output characteristics of generating units, hence rendering the CEED problem an imperfect optimization problem. As a benchmark test system for validating the efficacy of SHMFO, IEEE 30-bus systems are studied. Comparing the SHMFO method to other optimization strategies revealed its superiority and proved its capacity to resolve the CEED issue. The OPF is framed as a single or multiobjective problem with restrictions on generator capability, line capacity, bus voltage, and power flow balance to minimize fuel cost, emission, transmission loss, voltage deviation, etc. The numerical findings indicate that the SHMFO algorithm can provide cost-efficiency, diversity, and convergence in a single run. SHMFO performs better than the other algorithms and is an excellent choice for addressing the OPF problem, as shown by the results. On non-dominated solutions, a method adapted from the Technique for Ordering Preferences by Similarity to Ideal Solution (TOPSIS) is used to establish the Best Compromise Solution (BCS).

In this paper, Silicon-based MOSFET has been investigated with different gate oxides for knowing which oxide shows the best result. Silicon-di oxide (SiO2), gallium oxide (Ga2O3), and aluminum oxide (Al2O3) have been used as gate materials for observing the sensitivity, threshold voltage, and drain current of the MOSFET in this study. Al2O3 gate material gives the highest terminal current and faster turn-on voltage (0.7 V) of the MOSFET compared to the other two. Al2O3 delivers the best performance; and hence, it could be a promising material for the gate layer. In addition, electron and hole concentrations of those gate oxides and electric potential have been compared. In this paper, COMSOL Multiphysics® software has been used to simulate the obtained results.

In this paper, an intelligent low-cost wind turbine is designed which can rotate the rotor hub towards wind direction. The smart wind turbine technology has developed by using six rotor blades, squirrel cage induction generator (SCIG), and yaw mechanism. The yaw mechanism relates to two stepper motors through support tower. Based on the wind direction, the yaw mechanism will control the stepper motors. Finally, this stepper motors will move the wind turbine towards the wind direction. Conventionally, the hub of wind turbine is kept at fixed position. However, this kind of arrangement is not suitable where in some places (e.g. Bangladesh), the wind directions can be changed frequently. Therefore, it is necessary to move the rotor hub continuously towards the wind direction so that it can capture maximum amount of wind power. So, a smart wind turbine with yaw mechanism is designed in this paper.

Sign language is a system of communication that uses visual motions and signs to communicate with persons who are deaf or mute due to a hearing or speech impairment. A real-time Bangla Sign Language (BdSL) detection system was proposed in this paper, which can generate Bangla sentences from a sequence of images or a video feed which can help those who are not familiar with sign language. Blazepose algorithm was used to identify the sign language body posture sequence. After detecting the body posture the data was gathered as a numpy file. A Long Short-Term Memory (LSTM) network was used to train the numpy files since this network can generate predictions based on sequential data. After 85 epochs of training, the model's training accuracy was 93.85%, and its validation accuracy was 87.14%, which indicates that the model's ability to recognize BdSL sentences in real-time is adequate.

After 85 epochs of training, the model's training accuracy was 93.85%, and its validation accuracy was 87.14%, which indicates that the model's ability to recognize BdSL sentences in real-time is adequate.","PeriodicalId":389360,"journal":{"name":"2023 3rd International Conference on Robotics, Electrical and Signal Processing Techniques (ICREST)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123845501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
