Electric Servo Motor
A servo motor is a motor that uses feedback to control its motion and position. It consists of a motor, control board, and potentiometer connected to the output shaft. The potentiometer allows the control circuitry to monitor the shaft position and provide feedback to move the shaft to the desired angle between 0 and 180 degrees. Servo motors are used in applications like robotics and CNC machinery where precise control of motion and position is required. They are controlled through pulse width modulation signals that determine the shaft position based on pulse duration. Common types are rotary and linear servo motors that can have encoders or resolvers for position feedback.
Control system
Servo motors have an output shaft that can be positioned to specific angles by a coded input signal. They maintain the shaft position as long as the signal is present. Servo motors are constructed from basic DC motors with added gear reduction, a position sensor, and electronic control circuit. There are DC and AC servo motors that use different winding configurations and signals to control the shaft position. Servo motors offer advantages for sewing machines by precisely controlling speed and being silent when not in use while saving energy compared to clutch motors.

How does a servo motor work?
A servo motor works by using feedback to precisely control the position of its output shaft.

Rib roughened cooling passages for turbine cooling
In modern gas turbine engines, the continuous increase of power for an expected lifetime has resulted in a continuous increase of cycle pressure ratio and turbine inlet temperature. The later implies that advanced materials and cooling techniques must be adapted for a safe operation of the high pressure gas turbine blades and vanes. This need for high power and high efficiency gas turbine engines forces the designer to continuously increase the turbine inlet temperature. In recent military applications, the turbine inlet temperature could be as high as 2000K, far above the melting temperature of the most advanced vane and blade materials. Thus apart from the progress made in the metallurgical domain, a continuous cooling of blade of turbine 1st stages allows operating at temperatures which are far above material’s melting point without affecting component integrity and geometry. The efficiency of the blade cooling system is therefore strictly related to the safe operation of the engine and complete understanding of the convection mechanisms resulting from the cooling techniques is mandatory.
The most common internal heat transfer enhancement methods of heat transfer augmentation in gas turbine airfoils are ribs, pins, jet impingement, and flow disturbing inserts.To maintain the flow inside the cooling passage of turbine blade turbulent all these methods can be used. These devices act to increase turbulent mixing through the enhancement of turbulence.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
