Electric Current
The document discusses electric current and related concepts. It defines current as the flow of electric charge from one place to another, measured in amperes. Current can be direct or alternating. Resistance is a property that weakens current flow and is measured in ohms. Ohm's law states current is directly proportional to voltage and inversely proportional to resistance. Kirchhoff's laws govern the analysis of electric circuits.
Transformers
A transformer is an electric device that uses mutual induction to change alternating current voltages. It consists of two coils - a primary coil and secondary coil - wound around an iron core. Transformers can either step up or step down voltages. A step up transformer has fewer turns in the primary coil than the secondary coil, while a step down transformer has more turns in the primary coil. The alternating current passing through the primary coil induces an alternating current in the secondary coil through electromagnetic induction. Transformers are used to render current earth-free and alter voltages for different applications.
General Wave Properties
This document discusses different types of waves including transverse waves, longitudinal waves, and properties of waves such as amplitude, wavelength, frequency, and speed. It defines a wave as a spread of disturbance and notes that waves can transfer energy. It provides examples of transverse waves like water waves and electromagnetic waves, and examples of longitudinal waves like sound waves. It also defines key wave terms and properties and includes the wave equation relating wavelength, frequency, and speed.
Hookes law
This document explains Hooke's law, which states that the extension of a spring is proportional to the applied force. It defines elastic and plastic behavior, the spring constant, and the elastic limit on a graph. An example calculation demonstrates determining the spring constant k from measurements of force and extension using the equation F=kx. Key definitions are provided for Hooke's law, the spring constant, and a diagram to represent Hooke's law.
AC & DC
Electric current is the flow of electric charge through a conducting material. It is measured in amperes and defined as the rate of flow of positive charge from high to low electric potential. Resistance is a material property that impedes current flow and depends on resistivity, area, and length. Ohm's law states that current is directly proportional to voltage and inversely proportional to resistance. Direct current flows in one direction from positive to negative, while alternating current periodically reverses direction.
Waves - IGCSE physics

Sound waves
Sound waves are longitudinal mechanical waves that require a medium such as air or water to propagate. There are two types of mechanical waves: longitudinal waves where particles of the medium move parallel to the wave direction, and transverse waves where particles move perpendicular. Interference occurs when sound waves from different sources meet and combine to produce a new wave. Constructive interference amplifies the waves while destructive interference cancels them out. Infrasonic waves have frequencies below 20 Hz and ultrasonic waves are above 20,000 Hz, the normal human hearing range. Both have applications like monitoring earthquakes and welding.

In this 7th grade science project, the student explores different types of waves including light waves, mechanical waves, and sound waves. The project provides examples and interactive simulations of waves with crests and troughs. It also defines and gives examples of four main types of waves: sound waves, mechanical waves, electromagnetic waves, and matter waves.
Introducation of wave.pptx
Introduction to Waves PowerPoint presentation is an informative resource that provides an overview of the properties and behavior of waves. Following that, the discussion turns to wave properties such as reflection, refraction, diffraction, and interference. The discussion goes into how these characteristics relate to real-world phenomena such as sound waves, light waves, and ocean waves.
Understanding the behaviour of waves requires a grasp of wavelength, frequency, amplitude, and speed. The wavelength of a wave is the distance between two consecutive points in phase with each other, whereas frequency is the number of complete oscillations or cycles that a wave completes in a given time. The amplitude of a wave is the maximum displacement from its equilibrium position, whereas speed is the rate at which the wave travels.
Waves' qualities influence how they interact with matter. When a wave contacts an item or medium, its wavelength and speed may vary, affecting its frequency and amplitude. Knowing how these qualities influence wave behaviour is critical in many domains, includingphysics, engineering, and communication.
The inclusion of visual aids in the presentation, such as diagrams, animations, and pictures, assists learners in better understanding these topics. Diagrams and pictures can help to explain complex topics and make them easier to understand, whilst animations can show the movement of waves in a dynamic and interactive fashion. This method can assist learners in better retaining material and applying it to real-world settings.
Mechanical waves and electromagnetic waves are the two basic forms of waves.
Mechanical waves cannot pass through a hoover because they require a medium to move through. Mechanical waves transfer energy by creating a disturbance or vibration in the medium they travel through. Sound waves, water waves, and seismic waves are all examples of mechanical waves.
The disruption or vibration of the medium in a transverse wave is perpendicular to the direction of wave propagation. A wave on a string is an example of a transverse wave.
Longitudinal waves: The disturbance or vibration of the medium in a longitudinal wave is parallel to the direction of wave propagation. A sound wave is an example of a longitudinal wave.Electromagnetic waves can go through a howover and do not require a medium to move through. Electromagnetic waves are produced by the acceleration of electric charges and transfer energy via an interaction of electric and magnetic fields. Radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays are all examples of electromagnetic waves.
Electromagnetic waves are transverse waves, which means that their disruption or vibration is perpendicular to the direction of wave transmission.
Overall, the Introduction to Waves PowerPoint presentation is a comprehensive resource for anyone interested in learning more about waves.

Unit 4 2014 ppt wave characteristics
The document summarizes key concepts about waves, including:
1) Waves can be classified as mechanical or electromagnetic depending on whether they require a medium to travel. Mechanical waves include sound and water waves while electromagnetic waves include radio and light waves.
2) Waves can be transverse, with oscillations perpendicular to the direction of travel, or longitudinal, with oscillations parallel to the direction of travel.
3) Key wave properties include frequency, wavelength, period, amplitude, and speed. The speed of a wave depends on properties of the medium and can be calculated from the wavelength and period.

This document provides an introduction to radioactivity and nuclear physics. It discusses goals of learning about the physics of radioactivity, nuclear reactions, and their applications. It also covers hazards and safety mechanisms. Examples discussed include observing particle trails in a cloud chamber, the properties of alpha, beta and gamma radiation, and how intensity of radiation follows the inverse square law.
The Energy of Waves
The wavelength is inversely proportional to the frequency. If the frequency is doubled, the wavelength is halved. If the frequency is cut in half, the wavelength is doubled.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
