A REVIEW ON DESIGN OF PUBLIC TRANSPORTATION SYSTEM IN CHANDRAPUR CITY | J4RV4...Journal For Research
As we know the population of Chandrapur City has increased so far in this years and with that has increased the vehicles causing high traffic volume & rise in pollution. But the transportation system in Chandrapur City is still the same. To reduce the traffic volume & pollution, we have to study & design the new transportation system in Chandrapur City. The system would be as similar to Nagpur City with the implementation of Star City Buses. In this Study we would first compare the speed of various vehicles. Collection of population details of Chandrapur City, approximate number of vehicles running on road, collection of data with respect to Ticket fares in Nagpur City- whether it is according to Kilometers or places to be reached, calculation of Ticket Fares for Chandrapur City on the basis data collected. By all these, the best mode of transport in City can be studied. On the basis of above data collected from various respected fields, we will then proceed for the Design part of urban transport system in Chandrapur City. For Design purpose, firstly we have to mark the centre of the City, when the centre is decided; we will then select the Bus Terminus. From centre of the city, we would prefer to select the routes of the Buses. One route will be for the city side like Jatpura Gate, Pathanpura Gate. One route will be for Ballarpur going road. The other one for Mul going road, then next for Nagpur road. We could decide as many routes once we get the clear idea about all data. By getting all this details, the next step is to design the destination points of Buses. Then we have to design about the Bus bays, to reduce congestion in the particular intersections or Stops of bus. After the design also can suggest for Bus lanes. Implementation of Bus Rapid Transit System (BRT system) is the main aim behind to develop transportation mode of City. The design of the Transport System can be designed with the help of various software’s like AutoCAD and Revit.
The Prediction of Optimal Route of City Transportation Based on Passenger Occ...TELKOMNIKA JOURNAL
Currently, the existence of city transport is increasingly eliminated by private vehicles such as
cars and motorcycles. This situation is further exacerbated by the behavior of city transport drivers who are
less discipline in driving, or in picking up and dropping off their passengers. The bad behavior is partly
caused by the low level of passenger occupancy. The drivers try to search for passengers as much as
possible but often ignore the traffic rules. To overcome this problem, an optimal transport route with high
passenger potential is required. Therefore, this study investigated the optimal route of city transport based
on the passenger occupancy rate in the city of Bandung as the case study. The method employed for
determining the optimal route is Genetic algorithm combined with Ordinary Kriging method used for the
process of passenger prediction and fitness calculation. The optimal routes are those with higher
occupancy rate. The analysis results showed that the use of the Genetic algorithm with a low number of
generations succeed in creating new optimal routes even though the increase is not too high the maximum
only reaches 4%.This result is certainly important enough to be used in making better public transport
routes.
Planning for Metro Transit Transportation System a simplified Approach: A Cas...IJAEMSJORNAL
Currently Muscat the capital city of Oman is suffering from many traffic and transported related problems. Some of the serious concerns are high vehicle ownerships, low occupancy in personalized vehicles and poor patronization towards public transportation systems. Ruwi is the City center and a major Central Business District in Muscat. More than one million commuters daily visit Ruwi City center for their day to day business. The common transportation related problems often reported by the citizens at Ruwi CBD, are traffic congestion, over speeding of vehicles, inadequacy of parking places and pedestrian safety. All such problems can be eliminated by providing efficient public transportation system by restricting the entry of personal vehicles and para transit. In this technical paper, panning and designing of public transit facility by metro transport facility is attempted by capturing land use and travel information of daily commuters at Ruwi CBD area. An extensive literature review is carried for establishing the bench marking while planning metro transit system. For this the CBD area is cordoned and divided into traffic analysis zones based on the land use characteristics. Travel information of the commuter is estimated through interviewing them at the CBD entry gateway points and work locations. Land use characteristics are captured through reconnaissance of the area and random inspection of land parcels. Land use Information captured through the Google images and physical verification of data of the selected sample land parcels helped in estimation and characterization of the land use. Questionnaire survey at the activity centers helped in estimation of total trips attracted by the land uses. Travel characteristics, derived through the personal interviews of the commuters, facilitated for the estimation of total trips. Trip factors for different land uses are derived. Total trips generated are quantified and is used in planning of Metro Transit facility at the Ruwi city center. Commuter circulation pattern for the metro transit is also scheduled. Also it is proposed to carry extensive literature for establishing bench mark while planning the transit system.

A REVIEW ON DESIGN OF PUBLIC TRANSPORTATION SYSTEM IN CHANDRAPUR CITY | J4RV4...Journal For Research
As we know the population of Chandrapur City has increased so far in this years and with that has increased the vehicles causing high traffic volume & rise in pollution. But the transportation system in Chandrapur City is still the same. To reduce the traffic volume & pollution, we have to study & design the new transportation system in Chandrapur City. The system would be as similar to Nagpur City with the implementation of Star City Buses. In this Study we would first compare the speed of various vehicles. Collection of population details of Chandrapur City, approximate number of vehicles running on road, collection of data with respect to Ticket fares in Nagpur City- whether it is according to Kilometers or places to be reached, calculation of Ticket Fares for Chandrapur City on the basis data collected. By all these, the best mode of transport in City can be studied. On the basis of above data collected from various respected fields, we will then proceed for the Design part of urban transport system in Chandrapur City. For Design purpose, firstly we have to mark the centre of the City, when the centre is decided; we will then select the Bus Terminus. From centre of the city, we would prefer to select the routes of the Buses. One route will be for the city side like Jatpura Gate, Pathanpura Gate. One route will be for Ballarpur going road. The other one for Mul going road, then next for Nagpur road. We could decide as many routes once we get the clear idea about all data. By getting all this details, the next step is to design the destination points of Buses. Then we have to design about the Bus bays, to reduce congestion in the particular intersections or Stops of bus. After the design also can suggest for Bus lanes. Implementation of Bus Rapid Transit System (BRT system) is the main aim behind to develop transportation mode of City. The design of the Transport System can be designed with the help of various software’s like AutoCAD and Revit.
The Prediction of Optimal Route of City Transportation Based on Passenger Occ...TELKOMNIKA JOURNAL
Currently, the existence of city transport is increasingly eliminated by private vehicles such as
cars and motorcycles. This situation is further exacerbated by the behavior of city transport drivers who are
less discipline in driving, or in picking up and dropping off their passengers. The bad behavior is partly
caused by the low level of passenger occupancy. The drivers try to search for passengers as much as
possible but often ignore the traffic rules. To overcome this problem, an optimal transport route with high
passenger potential is required. Therefore, this study investigated the optimal route of city transport based
on the passenger occupancy rate in the city of Bandung as the case study. The method employed for
determining the optimal route is Genetic algorithm combined with Ordinary Kriging method used for the
process of passenger prediction and fitness calculation. The optimal routes are those with higher
occupancy rate. The analysis results showed that the use of the Genetic algorithm with a low number of
generations succeed in creating new optimal routes even though the increase is not too high the maximum
only reaches 4%.This result is certainly important enough to be used in making better public transport
routes.
Planning for Metro Transit Transportation System a simplified Approach: A Cas...IJAEMSJORNAL
Currently Muscat the capital city of Oman is suffering from many traffic and transported related problems. Some of the serious concerns are high vehicle ownerships, low occupancy in personalized vehicles and poor patronization towards public transportation systems. Ruwi is the City center and a major Central Business District in Muscat. More than one million commuters daily visit Ruwi City center for their day to day business. The common transportation related problems often reported by the citizens at Ruwi CBD, are traffic congestion, over speeding of vehicles, inadequacy of parking places and pedestrian safety. All such problems can be eliminated by providing efficient public transportation system by restricting the entry of personal vehicles and para transit. In this technical paper, panning and designing of public transit facility by metro transport facility is attempted by capturing land use and travel information of daily commuters at Ruwi CBD area. An extensive literature review is carried for establishing the bench marking while planning metro transit system. For this the CBD area is cordoned and divided into traffic analysis zones based on the land use characteristics. Travel information of the commuter is estimated through interviewing them at the CBD entry gateway points and work locations. Land use characteristics are captured through reconnaissance of the area and random inspection of land parcels. Land use Information captured through the Google images and physical verification of data of the selected sample land parcels helped in estimation and characterization of the land use. Questionnaire survey at the activity centers helped in estimation of total trips attracted by the land uses. Travel characteristics, derived through the personal interviews of the commuters, facilitated for the estimation of total trips. Trip factors for different land uses are derived. Total trips generated are quantified and is used in planning of Metro Transit facility at the Ruwi city center. Commuter circulation pattern for the metro transit is also scheduled. Also it is proposed to carry extensive literature for establishing bench mark while planning the transit system.

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.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
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

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
