Forgings- A Study of its Manufacturing Processes & Techniques
The term “Forging” is applied to processes in which a piece of metal is worked in a machine to the desired shape by plastic deformation of the starting stock. The energy that promotes deformation is applied by a hammer, press, up-setter or ring roller, either alone or in combination. The shape is imparted by the tools that contact the work piece and by careful control of the deformation process. A forging is produced in three distinct phases: stock preparation in the form of blooms, billets, bar or ingots; plastic deformation of the metal component to rough, close tolerance or net shape in one of the forging processes; and appropriate secondary operations

1. Stress is defined as force per unit area and can be calculated using the formula stress = force/area. The main types of stress are axial/normal stress, shear stress, and bearing stress.
2. Strain is the ratio of deformation to original length and is calculated using the formula strain = change in length/original length. Hooke's law states that stress is proportional to strain within the elastic limit defined by a material's Young's modulus.
3. Additional concepts covered include thin-walled pressure vessels, Poisson's ratio, thermal deformation, and stress-strain diagrams. Worked examples are provided to demonstrate calculating stresses, strains, deformations and other mechanical properties.
4. Shear Test
Shear stress acts parallel to the surface on which it acts and is produced by a force parallel to that surface. Normal stress acts perpendicular to the surface and is produced by a perpendicular force. Shear stress is calculated by dividing the applied shear force by the cross-sectional area parallel to the force. In an example, a 1-inch diameter bolt experiencing a 4,000 lb force has a shear stress of 5,096 psi.

Problems on triaxial loading and stresses on inclined planes for uniaxial and...
A metallic bar measuring 300 mm x 100 mm x 40 mm is subjected to tensile forces of 5 kN, 4 kN, and 6 kN along the x, y, and z axes respectively. The document calculates the changes in length, breadth, depth, and volume of the bar due to these tensile forces. It uses the given values of Young's modulus (2x105 N/mm2) and Poisson's ratio (0.25) to determine the stresses in each direction and resulting strains. The calculations show the lengthening, narrowing, and shallowing of the bar under the triaxial tensile loading.

Recycled Concrete Aggregate in Construction Part III
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
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

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.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
