components for developing a smart door lock using Arduino that provides
excellent security and quick access. The following are the specific project
goals:
• Familiarity with a smart door locking system based on a microcontroller.
• Using Arduino to create a simple and smart door locking system

Hardware & software
1. Arduino
• Arduino is an open-source platform used for building electronics projects.
• Arduino consists of both a physical programmable circuit board (often
referred to as a microcontroller) and a piece of software, or IDE (Integrated
Development Environment) that runs on your computer, used to write and
upload computer code to the physical board.

Hardware & software
1. PWM Powered servo motor:
• A servo motor is a rotational or translational motor that receives power from
a servo amplifier and is used to impart torque or force to a mechanical
device like an actuator or a brake.
• A closed-loop control system is used with this type of motor. A closed-loop
control system takes the current output into account and adjusts it to the
desired state.

Hardware & Software
3. 4*3 Matrix keypad:
• This 4x3 matrix keypad has 12 built-in pushbutton
contacts connected to row and column lines.
• A microcontroller can scan these lines for a button-pressed state.

Hardware & Software
4. 16*2 Alphanumeric display:
• An LCD (Liquid Crystal Display) screen is an electronic display module and
has a wide range of applications.
• A 16x2LCD is a very basic module and is very commonly used in various
devices and circuits.
• A 16x2 LCD means it can display 16 characters per line and there are 2 such
lines.

Working
1. The lock will open: A Keypad will input values allowing us to compare the values
with the string of integer values that are set in the code.
• The keypad will send a signal to the display and the “Code Accepted” message
• If the codes accepted, the Arduino will send a signal to Servo Motor. The Motor will
then rotate 90° and open the lock, allowing the door to be unlocked.
2. The lock will not open: If the code inserted in the Keypad does not match the fixed
string in the code, the Keypad will send a signal to the Display to show the “Wrong
Code” message.

PREDICTION OF ROOM TEMPERATURE SIDEEFFECT DUE TOFAST DEMAND RESPONSEFOR BUILD...ijccmsjournal

In order to evaluate side-effect of power limitation due to the Fast Automated Demand Response (FastADR) for building air-conditioning facilities, a prediction model on short time change of average room temperature has been developed. A room temperature indexis defined as a weighted average of the entire building for room temperature deviations from the setpoints. The index is assumed to be used to divide total FastADRrequest to distribute power limitation commands to each building.In order to predict five-minute-change of the index, our combined mathematical model of an auto regression (AR) and a neural network (NN) is proposed.In the experimental results, the combined model showedthe root mean square error (RMSE) of 0.23 degrees, in comparison with 0.37 and 0.26 for conventional single NN and AR models, respectively. This result is satisfactory prediction for required comfort of approximately 1 degree Celsius allowance.

3d Printing Nano composites As the world of technology continually drives the scientific community and the development of innovative instrumentation, it is important for the analytical chemist to be certain to take advantage of the wide range of knowledge that can be gained by using multiple modes of analysis. No single instrument is capable of entirely characterizing a material; therefore, the knowledge gained from multiple modes of analysis must be pieced together in order to provide the most accurate description of the sample. Using a single method only provides one dimension, but with the use of additional methods the analysis is multi-faceted. Instrument systems are designed to gather a distinct set of data, with no single system providing complete analysis. By coupling traditional thermal analysis techniques such as thermogravimetric (TGA), thermomechanical (TMA), and dynamic scanning calorimetry (DSC) with spectroscopic techniques such as Fourier Transform Infrared (FTIR), mass spectroscopy (MS), and X-ray diffraction (XRD), all aspects surrounding the materials physical and chemical properties can be determined almost entirely. Specifically the importance of evolved gas analysis (EGA), thermal-IR, XRD, and micro-thermal analysis will be discussed.

The development of smart cities holds immense significance in shaping a nation's urban fabric and effectively addressing urban challenges that profoundly impact the economy. Among these challenges, road accidents pose a significant obstacle to urban progress, affecting lives, supply chain efficiency, and socioeconomic well-being. To address this issue effectively, accurate forecasting of road accidents is crucial for policy formulation and enhancing safety measures. Time series forecasting of road accidents provides invaluable insights for devising strategies, enabling swift actions in the short term to reduce accident rates, and informing well-informed road design and safety management policies for the long term, including the implementation of flyovers, and the enhancement of road quality to withstand all weather conditions. Deep Learning's exceptional pattern recognition capabilities have made it a favored approach for accident forecasting. The study comprehensively evaluates deep learning models, such as RNN, LSTM, CNN+LSTM, GRU, Transformer, and MLP, using a ten-year dataset from the esteemed Smart Road Accident Database in Hubballi-Dharwad. The findings unequivocally underscore LSTM's superiority, exhibiting lower errors in both yearly (RMSE: 0.291, MAE: 0.271, MAPE: 6.674%) and monthly (RMSE: 0.186, MAE: 0.176, MAPE: 5.850%) variations. Based on these compelling findings, the study provides strategic recommendations to urban development authorities, emphasizing comprehensive policy frameworks encompassing short-term and long-term measures to reduce accident rates alongside meticulous safety measures and infrastructure planning. By leveraging insights from deep learning models, urban development authorities can adeptly shape the urban landscape, fostering safer environments and contributing to global safety and prosperity.

Smart Door locking system using arduino

1. Smart Door Locking System using Arduino Presented to: Presented by: Miss Charu Upadhyay Bhawna Singh (Assistant professor) 90515

2. Content • Introduction • Objective • Hardware & software used • Working • Conclusion

3. Introduction • In our daily lives, safety is a major concern. Every person requires a sense of safety. Our security pattern includes an access control system for doors. • We need to create a system that will assist 24 hours a day, seven days a week. • Only authorized individuals have access to restricted areas thanks to a password-based door lock system. • Arduino is in charge of the entire system. A keypad can be used to enter the password. The door opens if the password matches the password entered in Arduino.

4. Objective 1. The goal of this project is to research and analyse a suitable collection of components for developing a smart door lock using Arduino that provides excellent security and quick access. The following are the specific project goals: • Familiarity with a smart door locking system based on a microcontroller. • Using Arduino to create a simple and smart door locking system

5. Hardware & software 1. Arduino • Arduino is an open-source platform used for building electronics projects. • Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.

6. Hardware & software 1. PWM Powered servo motor: • A servo motor is a rotational or translational motor that receives power from a servo amplifier and is used to impart torque or force to a mechanical device like an actuator or a brake. • A closed-loop control system is used with this type of motor. A closed-loop control system takes the current output into account and adjusts it to the desired state.

7. Hardware & Software 3. 4*3 Matrix keypad: • This 4x3 matrix keypad has 12 built-in pushbutton contacts connected to row and column lines. • A microcontroller can scan these lines for a button-pressed state.

8. Hardware & Software 4. 16*2 Alphanumeric display: • An LCD (Liquid Crystal Display) screen is an electronic display module and has a wide range of applications. • A 16x2LCD is a very basic module and is very commonly used in various devices and circuits. • A 16x2 LCD means it can display 16 characters per line and there are 2 such lines.

9. Working 1. The lock will open: A Keypad will input values allowing us to compare the values with the string of integer values that are set in the code. • The keypad will send a signal to the display and the “Code Accepted” message • If the codes accepted, the Arduino will send a signal to Servo Motor. The Motor will then rotate 90° and open the lock, allowing the door to be unlocked. 2. The lock will not open: If the code inserted in the Keypad does not match the fixed string in the code, the Keypad will send a signal to the Display to show the “Wrong Code” message.

10. Conclusion • Thus “Smart Door Locking System using Arduino” is a modern successor of the conventional door locking system. • The conclusion of the discussion of smart Lock using Arduino is the innovation created from the lock system with no more direct contact between the user and the lock. • This system is very cost-effective and easy to install. In conclusion, it was discovered that the project performed according to specification and can be implemented. • The use of the Arduino UNO microcontroller in this project allows for design simplicity, hence, the project can be achieved in lesser time compared to other techniques previously employed.
