RAM and ROM are both types of computer memory, but they differ in how they store and access data. RAM can be read and written to during operation and loses its memory when powered off, while ROM is permanent and can only be read from as it retains data even without power. This document by Mohamed Morsy Elsaied explores the key differences between RAM and ROM such as volatility, speed of access, cost, and how they are used in computing systems.

Wave
The document discusses the wave equation for electromagnetic waves. It begins by deriving the wave equations for the electric and magnetic fields from Maxwell's equations. These are vector wave equations that describe wave propagation in free space. The equations are then specialized to the scalar wave equation for waves propagating in a single direction. Solutions to these wave equations describe plane electromagnetic waves in free space and good conductors. Characteristics of plane waves like attenuation constant, phase constant, velocity, wavelength, and phase difference between electric and magnetic fields are also defined.
Mixers
The document discusses mixers and their operating principles. It begins with a brief history of mixers and their development. It then explains how mixers work by multiplying two input signals together to generate sum and difference frequencies at the output. The document discusses different types of mixers including single-ended mixers, double balanced mixers, and image rejection mixers. It also covers modulators, balanced modulators, and product detectors which operate on similar mixing principles. Key aspects that make a good mixer like linearity and rejection of unwanted signals are also outlined.
Radar Systems -Unit- I : Radar Equation
This document provides an overview of the course content for Unit 1 of a radar systems course. The key topics covered include the modified radar range equation, signal-to-noise ratio, probability of detection and false alarms, integration of radar pulses, radar cross section of targets, creeping waves, transmitter power, pulse repetition frequency and range ambiguities, and system losses. The document also provides qualitative explanations and equations for several radar concepts.
Interferences
1) Frequency reuse in cellular networks results in co-channel interference from signals using the same frequency band but located in different cells.
2) Under normal conditions, co-channel signals do not interfere due to being located outside the cell boundary. However, troposcattering and transmission power issues can cause co-channel interference.
3) Measuring the carrier-to-interference ratio and carrier-to-noise ratio can help quantify co-channel interference levels. Frequency reuse increases spectrum efficiency but also co-channel interference, so reduction techniques are important.

GSM channels
Physical channels carry information over the air interface between the mobile station and base transceiver station. Logical channels map user data and signaling information onto physical channels. There are two main types of logical channels - traffic channels which carry call data, and control channels which communicate service information. Control channels include broadcast channels which transmit cell-wide information, common channels used for paging and access procedures, and dedicated channels for signaling during calls or when not on a call. Logical channels are mapped onto physical channels to effectively transmit information wirelessly between network components in a GSM system.
DCS - Distributed Control System
The document discusses distributed control systems (DCS), including their evolution, architecture, components, and applications in power plants. A DCS decentralizes control of an entire plant or manufacturing system across multiple controllers that communicate with each other. It allows for monitoring and control of all processes, identification of faults, and improved safety. A typical DCS architecture includes servers to collect and share data, archives for data storage, operator stations to monitor processes and alarms, engineering stations to configure the system, master controllers to supervise devices and modules, and field devices where the actual processes take place. DCS systems are hierarchical with lower-level controllers handling basic functions and higher-level controllers coordinating plant-wide control.

Tap Changer
Tap changers are devices fitted to power transformers that regulate output voltage levels by altering the transformer turn ratios (paragraph 1). On-load tap-changers (OLTCs) are commonly used in power grids and industries to continuously regulate voltage during operation (paragraph 2). OLTCs offer variable control to maintain supply voltage within specified limits by selecting different transformer taps, which correspond to different turn ratios and voltage outputs (paragraphs 3-5). Modern OLTCs are designed to change taps while energized since off-load tap changers interrupt power supply (paragraph 6).

Safe Operation and Maintenance of Circuit Breakers and Switchgear
Switchgear plays an important role in electricity distribution and its performance significantly affects the overall performance of the system. Failure to efficiently disconnect faults elsewhere in the network or failure in switchgear itself is costly, resulting in additional loss of supply, damage to equipment and possibly fatal injury to personnel. It is therefore critically important that switchgear is operated and maintained correctly, within an overall asset management regime that is both economic and effective in securing a high level of system reliability.
This comprehensive workshop focuses on medium voltage switchgear, which comprises by far the bulk of switchgear on most electricity distribution systems. The emphasis is primarily on oil, air blast, SF6 and vacuum circuit breakers, but other forms of MV switchgear, for example ring main units and auto-reclosers will also be described.

Selection Of Circuit Breaker
This document discusses the selection of circuit breakers. It begins by defining a circuit breaker as a protective device that is used to automatically open the faulty part of a power system during a fault. There are two main factors considered when selecting a circuit breaker: 1) its normal working power level and fault level ratings, which are specified by the rated interrupting current or MVA, and 2) its momentary current and speed ratings. The momentary current rating must be higher than the maximum current during fault conditions, while the speed rating depends on transient fault currents and specified cycles. Multiplying factors are used to determine the circuit breaker's short circuit interrupting current from fault analysis calculations.
Satellite link design
This document provides an overview of satellite communication link design. It discusses basic transmission theory including the link equation and factors that affect received power such as EIRP, path loss, and antenna gains. It also covers system noise temperature and the G/T ratio. The document outlines considerations for designing downlinks and uplinks. It describes how to calculate overall C/N ratio when multiple C/N ratios are present in the link. Finally, it lists the typical steps involved in designing a satellite communication link for a specified C/N requirement.
Servomechanism in Control systems engineering
A servomechanism is a closed-loop control system that uses feedback to accurately control a device. It consists of a controlled device, an output sensor, and a feedback system. The feedback system compares the output signal to a reference input and generates a third signal to control the device. This process continues until the output matches the reference input. A servo motor is a type of servomechanism that uses a DC motor, potentiometer, gearing, and control circuitry to rotate a shaft to a desired position based on feedback. It reduces motor speed through gearing while increasing torque. The potentiometer provides feedback of the shaft position to the control circuitry, which drives the motor until the positions match, stopping
Fpga vs asic
FPGAs are faster, cheaper, and smaller than ASICs for small applications but ASICs are faster, cheaper, and smaller for large, complex applications due to their ability to be optimized for a specific application. FPGAs consume more power and take less time to design than ASICs which require more complex design processes like floor planning and mask production. For these reasons, FPGAs are better for applications requiring fast design time while ASICs are better for high volume applications seeking maximum optimization of speed, cost, size and power.
Pacemaker
A pacemaker is a medical device that uses electrical pulses to regulate an abnormal heart rhythm. It has a pulse generator that provides electrical stimulation through electrodes to contract the heart muscles. The first pacemaker was created in 1926 and the first successful implantation was in 1958. There are different types including permanent pacemakers, which are implanted devices with batteries lasting 6-20 years, and temporary external pacemakers. A permanent pacemaker has a pulse generator, leads to transmit pulses, and can pace one or both chambers of the heart. It regulates heart rate and energy output.

Swine influenza
Swine influenza, or swine flu, is a respiratory virus that normally infects pigs but can be transmitted to humans. It causes symptoms like fever, cough, sore throat, and body aches. The virus spreads through coughing or sneezing of infected individuals. While usually mild, it can lead to severe illness in some cases. There are several strains of swine flu virus that have caused outbreaks in pigs and spread to humans throughout the 20th and 21st centuries. Eating properly handled pork does not transmit the virus.
Smoth muscle tissue
This document discusses smooth muscle tissue. It defines smooth muscle as non-striated muscle that lacks sarcomeres and is usually involuntary. There are two types of smooth muscle: single unit (visceral) muscle found in organs, and multiunit muscle like the ciliary muscle. Smooth muscle is composed of spindle-shaped cells with a central nucleus. Contraction is triggered by calcium ions causing actin and myosin filaments to slide past each other. Smooth muscle contraction is controlled by the autonomic nervous system, local tissue factors, hormones, and stretch.

11TH INTERNATIONAL CONFERENCE ON ELECTRICAL, ELECTRONIC AND COMPUTING ENGINEERING
3-6 June 2024, Niš, SerbiaDEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
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%.
