Troughed belt conveyors with minimum cord pitch

This document presents a study that aims to simplify the process of determining train load effects on bridges. It analyzes simply supported bridges with spans ranging from 5m to 40m under IRC Class A, AA and 70R train loadings. Equivalent uniformly distributed loads are used to calculate maximum bending moments and shear forces at different span locations. Charts are developed showing variations in bending moment and shear force with span length. These charts allow bridge engineers to easily determine design forces for different load cases, improving efficiency over traditional load placement calculations. In conclusion, the charts make it simple to identify critical sections and ensure structural adequacy under shifting single train loads.

Mani Vel

This document discusses curves and superelevation on railways. It defines horizontal and vertical curves, and explains that superelevation involves raising the outer rail on a curve to provide a comfortable ride. Superelevation counters the effects of lateral forces when negotiating a curve. The key points are: - Superelevation is the difference in height between the inner and outer rails and helps distribute load on both rails. - Equilibrium speed is when the centrifugal force is balanced by the cant (superelevation), providing no unbalanced radial acceleration. - Maximum permissible speed considers factors like radius, cant, cant deficiency/excess, and transition length. - Examples are provided to calculate supere

Geometric design of the track

T.Naga Anusha

Geometric design of tracks aims to provide smooth and safe running of trains at maximum speed while carrying heavy loads. This involves proper design of gradients, curvature, and super elevation (cant). There are different types of gradients - ruling gradient which is the maximum gradient permitted, momentum gradient which is steeper and uses train momentum, and pusher gradient requiring extra locomotives. Gradients are designed considering train performance and load. Curvature introduces greater resistance requiring grade compensation of ruling gradients. Super elevation (cant) involves raising the outer rail on curves to counteract centrifugal forces. Equilibrium cant provides equal wheel load distribution. Higher speeds result in cant deficiency which must be limited for passenger safety. Contrary flexures like

Axle load for Rail way - linkedin

Hamad Al-oqayli

The document discusses axle load in railways, which is the total weight felt by the railway for all wheels connected to a given axle. It is important for track design as both tracks and vehicles are rated for a maximum axle load to prevent damage. The dynamic loads from moving trains exceed static loads. Track strength depends on factors like rail weight, sleeper density, stability, and ballast. Loads transfer downward through the components of the track structure. Formulas like Nadal and Wagner relate vertical and lateral wheel and rail forces, which must be properly balanced to prevent wheel climb derailments during turns.

Track usually consists of steel rails installed on sleepers/ties and ballast. Sleepers bear the force of the track and act as an elastic medium to absorb blows and vibrations from passing trains. They help maintain the lateral stability, direction, position and gauge of the track. Rails guide conical, flanged train wheels and keep vehicles on the track without active steering, allowing trains to be much longer than road vehicles. Rails must be made of high quality steel to withstand high static and dynamic stresses from heavy loads and lateral forces at curves.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM

HODECEDSIET

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

jpsjournal1

The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been referred to as the "New Great Game." This research centres on the power struggle, considering geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil politics, and conventional and nontraditional security are all explored and explained by the researcher. Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role in Central Asia. This study adheres to the empirical epistemological method and has taken care of objectivity. This study analyze primary and secondary research documents critically to elaborate role of china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade, pipeline politics, and winning states, according to this study, thanks to important instruments like the Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study, China is seeing significant success in commerce, pipeline politics, and gaining influence on other governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai Cooperation Organisation and the Belt and Road Economic Initiative.

IJECEIAES

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
