Wave classification powerpoint2
There are two main ways that waves can be classified: by what they move through (the medium) and by how the energy moves through the medium. Waves that require a medium are mechanical waves like sound, water, and seismic waves. Electromagnetic waves can travel through matter or empty space. Mechanical waves are further divided into compressional/longitudinal waves where the medium vibrates parallel to the wave direction, and transverse waves where the medium vibrates perpendicular to the wave direction. Examples of each type of wave and their characteristics are provided.

Waves
Waves carry energy through matter or space in different forms. There are two main types of waves - mechanical waves which require a medium and electromagnetic waves which do not. Mechanical waves include waves on strings, springs, water surfaces and sound waves. Electromagnetic waves include visible light, infrared, radio waves, x-rays and gamma rays. A medium is the material that mechanical waves travel through such as solids, liquids, gases or combinations. Waves can be periodic, meaning the medium particles oscillate repeatedly.
Types of waves
There are two main types of progressive waves: transverse waves and longitudinal waves. Transverse waves involve particle motion perpendicular to the direction of wave propagation, with crests and troughs. Longitudinal waves involve particle motion parallel to propagation, characterized by regions of compression and rarefaction where particles are close together or spread apart.

Okay, let's break this down step-by-step:
* Mr. H vibrates the snakey 32 times in 10 seconds
* So the frequency is 32/10 = 3.2 Hz
* There are 4 sections each occupied by an antinode
* Since there are nodes between each antinode, there must be 5 nodes total
* With 5 nodes, this is the 5th harmonic standing wave pattern
* The 5th harmonic has 6 nodes
* So the wavelength is the total length (6.2 m) divided by 6 nodes
* Wavelength = 6.2 m / 6 = 1.033 m
* Using the wave equation: Speed = Frequency x Wavelength
* Speed = 3

It describes two main types of waves: transverse waves, where the medium moves perpendicular to the wave direction, and compressional (longitudinal) waves, where the medium vibrates parallel to the wave direction. Key wave properties discussed include amplitude, wavelength, frequency, and speed. The relationship between these properties is defined by the wave speed equation. Examples of different types of waves are given.
Waves Intro
Waves transport energy through a medium rather than matter. There are two main types of waves: transverse waves, where the medium moves perpendicular to the wave's direction of travel, and longitudinal waves, where the medium moves parallel to the direction of travel. Key wave parameters include amplitude, wavelength, frequency, period, and speed. The wavelength is the distance between two equivalent points on consecutive waves, frequency is the number of waves passing a point per second, and speed depends on the properties of the medium and can be calculated as speed equals wavelength times frequency.
MAHARASHTRA STATE BOARD PHYSICS Chapter 6 - SOUND
The document discusses sound waves and their properties. It begins by asking how students know when a class is over, noting they hear the school/college bell. It then discusses different types of waves like longitudinal waves, which have particles vibrating parallel to the direction of propagation like sound waves. Transverse waves have particles vibrating perpendicular to the direction of propagation. Key properties of waves discussed include amplitude, wavelength, frequency, period, and velocity. The document is a chapter from a physics textbook that provides information on sound waves and summarizes different wave types and their characteristics.
04 Oscillations, Waves After Class
This is lecture 4, Oscillations and Waves. For Conceptual Physics course, Physics 102, at University of New Mexico. Koch's section.
Electromagnetic radiation
Electromagnetic radiation (EMR) is a form of energy that can transfer through empty space and consists of oscillating electric and magnetic fields perpendicular to each other and the direction of propagation. EMR travels at the speed of light and can be described using both wave and particle models. The wave model conceives EMR as waves characterized by amplitude, wavelength, frequency, and speed of light. Shorter wavelengths correspond to higher frequencies and more energy. EMR interacts with matter by reflecting, absorbing, or transmitting depending on the material. The particle model views EMR as discrete packets of energy called photons whose energy is determined by the photon's frequency and Planck's constant.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
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.

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).
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
