MACHINE LEARNING MODELS FOR STOCK PRICE PREDICTION: A COMPREHENSIVE REVIEW OF DSE APPLICATIONS
The prediction of stock prices remains a complex challenge due to the non-linear and volatile nature of financial markets. Traditional methods, such as fundamental and technical analyses, struggle to capture these complexities, limiting their effectiveness. This study examines the application of machine learning (ML) techniques to improve stock price forecasting, focusing on the Dhaka Stock Exchange (DSE). The research aims to explore how ML models, including supervised learning, deep learning, and hybrid approaches, can enhance prediction accuracy by identifying complex patterns in large datasets. The study reviews various methodologies, including Long Short-Term Memory (LSTM) networks, Support Vector Machines (SVM), and ensemble models, alongside hybrid models that combine artificial neural networks (ANN) with technical indicators like Moving Average Convergence Divergence (MACD) and Relative Strength Index (RSI). Time series data from the DSE is used in these studies to evaluate prediction performance. The results show that ML techniques significantly outperform traditional methods in forecasting short-term stock price trends. Hybrid models, particularly those integrating ANN with technical indicators, offer higher precision. The incorporation of sentiment analysis and big data analytics further improves model adaptability to dynamic market conditions. The major findings indicate that while ML models enhance prediction accuracy, challenges such as the limited availability of high-quality datasets, the lack of integration of macroeconomic factors, and difficulties in real-time validation remain. The DSE’s high volatility and sectoral variability further complicate accurate predictions. JEL Classification Codes: H54, P42, G17, C88.

ANALYTICAL EXAMINATION OF NANO-FLUID-ASSISTED COOLING RATE ENHANCEMENT IN A CAR RADIATOR
In recent years, nanofluids have been extensively utilized to improve heat transmission in various mediums. The use of nanofluids can enhance the thermal efficiency of thermosyphons. This study focuses on analyzing the thermal efficiency of automobile radiators by utilizing three different types of nanofluids. In this study, we conducted a thermal performance analysis of a car radiator by examining the effects of three different types of nanoparticles mixed with water: CuO-water, ZnO-water, and MgO-water nanofluids. The thermal performance of these three nanofluids was compared and analyzed. The experimental setup included a radiator with a hydraulic diameter of 0.0191 m and a total length of the radiator channel of 10.5354 m. The analyses are conducted at different volume fractions, ranging from 0.5% to 3%, and a constant inlet velocity of 0.24 m/s is maintained. The findings demonstrated a substantial enhancement in thermal efficiency when employing CuO-water nanofluid as a coolant for vehicle engine cooling in the radiator. Conversely, ZnO-water and MgO-water nanofluids exhibited very limited improvements in comparison to pure water. The thermal conductivity of CuO-water nanofluid is greater than that of pure water. The CuO-water nanofluid yields the most significant enhancements in terms of the mass flow rate and heat transfer coefficient, as revealed by this investigation. Hence, it is advisable to utilize CuO-water nanofluid in automobile radiators to achieve optimal heat transfer efficiency in comparison to the base fluid. JEL Classification Codes: O31, O32, Q40.

STOCK MARKET PRICE PREDICTION USING MACHINE LEARNING TECHNIQUES
Predicting stock market prices is a challenging task in the financial sector, where the Efficient Market Hypothesis (EMH) posits the impossibility of accurate prediction due to the inherent uncertainty and complexity of stock price behaviour. However, introducing Machine Learning algorithms has shown the feasibility of stock market price forecasting. This study employs advanced Machine Learning models that can predict stock price movements with the right level of accuracy if the correct parameter tuning and appropriate predictor models are developed. In this research work, the LSTM model, which is a type of Recurrent Neural Network (RNN), time series forecasting Facebook Prophet algorithm and Random Forest Regressor model have been implemented on 10 Dhaka Stock Market (DSEbd) listed companies and six international giants for predicting the stock and forecasting the future price. The dataset of domestic companies is extracted from the graphical representation of the DSEbd website, and the international companies' dataset is imported from Yahoo Finance. In this experiment, Facebook Prophet demonstrates a long period of forecasting with reasonable accuracy, capturing daily, weekly, and yearly seasonality, including holiday effects for market trend analysis. Remarkably, the LSTM model exhibits significant accuracy, yielding the best results with evaluation metrics, including RMSE (0.35), MAPE (0.50%), and MAE (0.30). The experimental results underscore the efficiency of LSTM for future stock forecasting, observed over 15 days of upcoming market prices. A comparison of the results shows that the LSTM model efficiently forecasts the next day's closing price. JEL Classification Codes: H54, P42, G17, C88.

SIMULATING THE DRAG REDUCTION MODEL FOR A VEHICLE BY USING VORTEX GENERATOR
Petroleum fuel consign has been lessening at a very high proportion. Almost all automobiles depend upon an IC engine driven by petroleum fuels. As much as the number of automobiles is developing in this modern world, it is obligated to reduce fuel expenditure. One of the ways to do this is to diminish the car's drag. Among a manifold process of reducing drag, using Vortex Generators is one. Delta-shaped vortex generators are used at the rear trunk of the range rover, where the flow separates. K-epsilon turbulent model in ANSYS-Fluent 19.2 software is used to imitate the airflows. This work observed the number and spacing between successive vortex generators based on comparing drag coefficient values. The contours of static pressure and velocity magnitude were also observed for each model. When the vortex generators were attached, the pressure coefficients at the rear trunk began to increase, confirming the increment in back pressure. Hence, the increase in back pressure indicates a reduction in the drag coefficient. It has been found that a combination of 7 vortex generators is the optimum solution. The devices work better at a higher velocity than the lower velocity without affecting vehicle stability. The vortex - 4 model's drag coefficient was found to be significantly lower than that of the standard model vehicle, which is 0.42877. The Base Model of Range Rover (2020) is my sense of humor, the highest drag coefficient. So vortex generators are commonly used on automobile vehicles to prevent downstream flow separation and improve their overall performance by reducing drag. JEL Classification Codes: C61, R41, Q51.

THERMOELECTRIC POWER GENERAION FROM WASTE HEAT OF GAS STOVE BY USING THE THERMOELECTRIC GENERATOR
The objective of this research is set to produce energy by utilizing the unused heat of gas stove through thermoelectric generator. Currently, an increasing concern of environmental issues of emissions like greenhouse effects and the scarcity of fossil fuel has resulted in extensive research into the alternative ways of generating electrical power. Thermoelectric power generator has been considering as one of the promising alternatives due to its advantages. The application of this alternative option in converting waste-heat energy directly into electrical power that may also enhance the overall efficiencies of energy conversion systems. In this study, a gas burner was set to generate electricity that will produce waste heat. One thermoelectric unit is installed underneath the burner cap of the gas burner. Gas flame at the edge of the burner cap creates heat sources (hot side) for the thermoelectric unit. A gas-mixing chamber underneath the thermoelectric unit functions as heat sink (cold side) for the thermoelectric unit. An insulation plate is inserted in between the thermoelectric unit and the burner cap to control the hot side temperature. The thermoelectric unit generates electricity while the gas burner is in use and the flame heats up the burner cap. The thermoelectric unit connects to an electric circuit and provides electricity to power devices. JEL Classification Codes: Q41, Q42, Q43, Q56.

AN OVERVIEW OF HEALTH AND ENVIRONMENTAL THREATS FROM THE BRICK KILN INDUSTRY AROUND THE CAPITAL OF BANGLADESH
Bangladesh is one of the top brick manufacturing countries in the globe. With rapid urbanization and industrialization, the brick manufacturing industry is elevating to its peak level day by day and contributing to the country’s GDP significantly. This research aims to investigate the current environmental and health threat coming from brick kilns around the capital of Bangladesh. The selected areas are Savar, Tongi, Amin Bazar and Ashulia. The methodology followed in this study was field surveying in the selected areas and information acquisitions from the secondary data. Results from this study revealed that brick kilns are highly responsible for environmental pollution that subsequently deteriorates the air quality, causes land degradation, threatens biodiversity and poses a potential impact on human health. Results also revealed that there are mainly four types of brick kilns found in selected areas e.g. Chimney Kiln (CK), Zigzag kiln (ZK), Hoffman Kiln (HK) and Hybrid Hoffman Kiln (HHK). Of these, the Fixed Chimney Kiln is found to be very obsolete at present days and creates environmental pollution at different levels. Besides these, strict implementation of the Brick Manufacturing and Brick Kilns Establishment (Control) Act, 2013 in the studied locations is still far away. This paper urges the attention of the policymakers as well as the researchers to prioritize the solution to this promising but ever-increasing pollution-causing industry of Bangladesh in sustainable ways.

A COMPARATIVE STUDY OF MULTISTORIED BUILDING USING THE BUILDING INFORMATION MODELLING (BIM) METHOD & CONVENTIONAL MODELING METHOD
Although the construction industry has been evolving for centuries and researchers have been seeking innovative solutions for decades, diverse challenges still exist in making the construction process faster, safer, cheaper, and more accurate. Building Information Modelling (BIM) is one of the emerging tools in the field of architectural engineering to overcome these problems. Applications of this tool are very promising but its uses are still relatively limited in many countries including Bangladesh. So this study conducted a pilot project and case study analysis using Building Information Modeling (BIM) to control the project’s time and cost from Bangladesh's perspective. The objectives of this study are: (1) to examine the benefits of using BIM for project time and cost control and (2) to study the challenges of applying BIM to a case project during its life cycle. This project is being achieved by introducing Autodesk Revit MEP (2021) as the methodological tool of BIM software. The resultant data in the BIM system are extremely useful and can be generated to optimize the project delivery processes. The results also revealed that using a case study, BIM functions to help reduce costs, optimise the schedule, and make benefits for all project participants. Thus, model-based cost estimation and time schedule optimization show effective results of using BIM instead of conventional modelling methods. JEL Classification Codes: C60, L74, R20, R30

Wireless Speed Control for Induction Motor
Many motors are used for particular reasons in the vicinity, from home appliances to machine tools in manufacturing installations. These motors require comprehensive range features and efficiency, and the speed of the electric motor is often required for most applications. While this is not an issue for motors installed at readily available places, severe problems are presented with powered motors installed in dangerous areas, elevated altitudes, or off-site monitoring of these motors' speed. The design of a wireless speed control system for these motors is therefore necessary. In addition to ensuring that the wireless speed control of electric motors can readily regulate motors that are moving at high speed, the motor is also easy to use for off-site activities. The precise goal of this study is to create a wireless-based speed control system for an induction motor and to evaluate the finished product. Mechanical loads should not only be driven in industries, but they should also be driven at the desired speed. As a result, techniques for controlling the speed of induction motors are required. After implementing the use of arduino microcontroller and wireless module, we were able to control an induction motor which is an electric fan in this case.
