Supercapacitors store energy through a double-layer capacitance mechanism and have a higher energy density than traditional capacitors. They were first developed in 1957 and store energy in the interface between porous carbon electrodes and an electrolyte. Supercapacitors can charge and discharge rapidly, undergo hundreds of thousands of cycles with little degradation, and are being researched for applications in electric vehicles and transportation where high power is required. While they currently have lower energy density than batteries, advances in materials like carbon nanotubes and aerogels may help bridge this gap.
Ppt on super capacitors
Supercapacitors are energy storage devices that have evolved from conventional capacitors. They store charge through electrostatic double layer capacitance or electrochemical pseudocapacitance. There are different types of supercapacitors that store energy via these principles and have higher energy densities than conventional capacitors due to nanoscale porous electrode materials.
Supercapaitor
Supercapacitors are energy storage devices with a higher power density than batteries. They have a construction of two porous carbon electrodes separated by an electrolyte. Modern supercapacitors use nanotechnology by replacing the active carbon electrodes with vertically grown carbon nanotubes only 5nm in diameter. Supercapacitors allow for high-rate charging and discharging, good reversibility, and high cycle efficiency. They can find applications where high power is required, such as starting diesel engines, but have lower energy density than batteries.
Supercapacitors
Supercapacitors can store more energy than regular capacitors through electrochemical double layer capacitance. They provide very high charge/discharge rates, long cycle life, and high efficiency. While supercapacitors have lower energy density than batteries, they compensate with much higher power density and longer lifespan. Applications include public transportation, hybrid electric vehicles, backup power systems, and consumer electronics where high power delivery is needed.

Supercapacitor By praveen
Supercapacitors are electrochemical capacitors that can store unusually high amounts of energy compared to regular capacitors. They consist of two electrodes separated by an ion-permeable membrane and electrolyte. When voltage is applied, ions in the electrolyte form electric double layers on the electrodes, storing energy. Though supercapacitors have advantages like high power rates and longevity, their main disadvantage is lower energy storage per unit weight compared to batteries. They can be used for applications requiring high power or energy recuperation.

Density based Traffic Light Controller
This document describes a density-based traffic light controller system that uses sensors to measure traffic load and detect emergency vehicles. The system uses a microcontroller to automatically adjust signal timing based on traffic density during normal operation. When an emergency vehicle is detected, the system overrides normal timing to provide a green light in the direction of the emergency vehicle while blocking other lanes. The system is intended to help reduce traffic jams by adapting to current traffic conditions. Key components include IR sensors to detect vehicles, a microcontroller to control signal timing, and an RF receiver to detect emergency vehicles like ambulances.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
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.

our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

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
- **Efficient Use of Bandwidth**: TDM all
Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Advanced modeling of a 2 k w series–series resonating inductive charger for real electric vehicle
- 1. ADVANCED MODELING OF A 2-KW SERIES–SERIES RESONATING INDUCTIVE CHARGER FOR REAL ELECTRIC VEHICLE ABSTRACT This paper focuses on the design of a contactless charging system for electric vehicles (EVs) using inductive loops connected to a resonance converter. The study carries out the system operation, electromagnetic radiation, and testing. It is shown that the presence of the chassis leads to a double resonance and has a strong influence on the radiated fields.
