Laboratory tests were conducted to validate behaviors identified in previous simulation studies of bogie rotation friction under applied track twisting forces. Tests were performed on a full three-piece bogie mounted on a test wagon using the Centre for Railway Engineering's heavy test lab facility. The objectives were to examine the center bearing's longitudinal movement in transitions due to twisting, how the effective friction radius changes with center bearing tilt and rim contact, and how bogie warping deflection is affected. Results provided the effective center of rotation and friction radius under a pitching force on the bogie. Testing showed no sliding at the center bearings until large bolster rotations occurred due to the bearings' low elastic stiffness, with implications for simulation modeling of hunting performance

The document summarizes the key components and functions of a vehicle transmission system. It discusses the purpose of transmitting engine torque to drive the wheels. It then describes the main types of transmissions including manual, automatic, CVT, and their basic workings. The document also explains the purpose and function of key components that work together in a transmission system, such as the clutch, gearbox, driveshaft, differential, and universal joints.
There are four main powertrain configurations for vehicles: front-wheel drive (FWD), rear-wheel drive (RWD), 4-wheel drive (4WD), and all-wheel drive (AWD). FWD vehicles have the engine mounted transversely and power the front wheels. RWD vehicles have an inline engine and power the rear wheels through a transmission and driveshaft. 4WD vehicles can power all four wheels either full-time or on demand. Vehicles can also have mid-mounted or rear-mounted engines.
An automatic transmission can change gear ratios automatically as a vehicle moves, allowing the driver to not manually shift gears. It uses a planetary gearset and hydraulic system to provide different gear ratios. A continuously variable transmission (CVT) can change through an infinite number of gear ratios and was first conceptualized in 1490. Examples of CVTs include the Variomatic, first used in 1958, and the Multitronic introduced by Audi in 2000 which uses a chain drive and multi-plate clutch. CVTs operate smoothly without jerks between gears but can have slightly higher fuel consumption than manual transmissions in city driving.
An automatic transmission uses a torque converter, gear train, and hydraulic system to shift gears automatically based on engine load and vehicle speed. The torque converter connects the engine to the transmission and transfers power through fluid. It multiplies torque for better acceleration. The gear train includes planetary gear sets that provide multiple gear ratios. Hydraulic pressure acts through the transmission fluid to engage clutches and bands, producing gear shifts without driver input as the vehicle speed increases.

The document presents a method for 3D road profiling using stereography. Current techniques use static sensors or dynamic vehicle-mounted sensors combined with an IMU/INS system. The presented method uses stereography to capture overlapping 3D point grids at each sample, which are pieced together using feature tracking and registration techniques. This reduces the need for a high-accuracy, expensive IMU/INS system. The method is shown to provide reasonable accuracy for road profiling using inexpensive cameras.

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%.
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

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
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
