Finding the place of atom on periodic table from electron distribution
This presentation introduces electron distribution in atoms, focusing on periods 2 and 3 of the periodic table. It discusses how electrons are arranged in shells and provides information about halogens. The presentation concludes by thanking the audience and saying goodbye.
The Atom
The atom is the smallest piece of matter and is made up of protons, neutrons, and electrons. Protons and neutrons are packed tightly together in the nucleus at the center of the atom, which contains most of its mass. Electrons have a negative charge and orbit outside the nucleus. Most atoms contain the same number of protons and electrons, so the charges cancel out and atoms as a whole are electrically neutral.
Electron config
The document discusses electron configurations, which describe the arrangement of electrons in an atom's orbitals. Electron configurations are used to represent atoms in their ground state or as ions after gaining or losing electrons. Many of an element's physical and chemical properties can be correlated to its unique electron configuration, especially the valence electrons in the outermost shell. Knowing the electron configuration of an atom or ion allows us to better understand its bonding abilities, magnetism, and other chemical properties.

Sedimentary Rocks
The document discusses different types of igneous and sedimentary rocks. It states that igneous rocks form from cooled magma and their crystal size depends on the cooling rate, with slowly cooled rocks like granite having large crystals and quickly cooled rocks like basalt or pumice having small or no crystals. It describes sedimentary rocks as forming from compacted and cemented sediments, including pieces of other rocks, once-living things like plants and shells, and liquid solutions that leave impressions of fossils.
Metamorphic Rocks
Sandstone forms from cemented sand grains through compaction and cementation. Shale forms from compacted clay and mud sediments. Coal forms from compacted organic material. Limestone forms from cemented calcium carbonate sediments and shells. Sedimentary rocks like sandstone, shale, and limestone can contain fossils.
Earthquakes and Earthquake Waves
The document discusses the theory of plate tectonics. It states that the Earth's surface consists of large moving tectonic plates (E), and that the movement of these plates is driven by convection currents in the mantle (B). It also notes that plate tectonics supports phenomena like sea floor spreading (D) and is evidenced by features like mid-oceanic ridges and deep sea trenches (A). Finally, it indicates that plate tectonics theory provides explanations for earthquakes and mountain building (C).
Mixtures and Separating Mixtures
The document discusses physical and chemical changes, mixtures, and different ways to separate mixtures. It defines a mixture as two or more substances physically combined without a chemical reaction occurring. Mixtures can be either heterogeneous, with components not evenly distributed, or homogeneous, with even distribution making the mixture appear uniform. The document outlines various physical separation methods like straining, magnets, dissolving, evaporation, and exploiting differences in component densities.
Concept Map
Flora is boiling water on the stove. She turns the dial up to high, causing the water to boil vigorously with large, quickly forming bubbles. She then turns the dial down to low, causing the water to boil gently with smaller, slowly forming bubbles. Flora wonders if the boiling temperature changes with the dial settings. The correct answer is C - the boiling temperature remains the same at 100 degrees Celsius regardless of the dial setting.
Heat capacity
Mia and Devon are having a summer party and need to make two sizes of ice. They wonder if the temperature at which water freezes is affected by the size of the ice. Small ice cubes freeze at a lower temperature than large blocks of ice. This is because it takes more energy to freeze a larger volume of water, so large blocks of ice freeze at a slightly higher temperature than small ice cubes.
Density Anomaly
This document discusses buoyancy, density, and why ice floats. It explains that ice is less dense than water due to the formation of hydrogen bonds between water molecules that cause water to expand when it freezes. As a result, the buoyant force on ice is greater than its weight, causing ice to float on water.
Buoyancy
The document compares two solid cubes made of the same material but different sizes - one is large and one is small. It asks which statement about the density of the cubes is true. The correct statement is that the density of the larger cube is the same as the density of the smaller cube, because density is a property of the material and does not change with the size of the object.
Water
Water is a polar covalent compound composed of two hydrogen atoms and one oxygen atom. The electrons in the covalent bonds are shared unequally, with the hydrogen side being partially positive and the oxygen side being partially negative. This gives water molecules a polar nature. Water exhibits both cohesion, the attraction of water molecules to one another, and adhesion, the attraction of water molecules to other substances. Due to its high surface tension, water forms a "skin" on its surface that requires a force to break. When placed in a glass, the water curves up the sides due to surface tension forming a meniscus.
Friction
The document provides an assignment to investigate the impact of fertilizer amounts on plant growth. To properly conduct this investigation, the following factors would need to be controlled: the amount of water given to each plant, keeping track of the fertilizer amounts given to each plant, starting with plants of the same size, and keeping all plants in a similar location. Variables like the amount of fertilizer and location of the plants would need to be manipulated, while the dependent variable of plant height would be measured.
Scientific Method
The document outlines the key steps of the scientific method, which are: 1) identifying a problem or question, 2) researching existing knowledge, 3) forming a hypothesis, 4) testing the hypothesis through experimentation, 5) recording and studying the data, 6) forming a conclusion, and 7) communicating the results. It also defines key terms used in the scientific method, such as hypothesis, variables, control, and constant.
First Day Stuff
This document outlines classroom procedures for an integrated science class taught by Mr. Windsor. It details the daily schedule, which includes 10-15 minutes for warm-up and homework check, 25-30 minutes for lecture and demonstrations, lab/activities that vary in length and format, and 20-25 minutes for quizzes and videos. The document also covers safety procedures for working with electrical and mechanical equipment, as well as chemical hazards, including the Right to Know Law, chemical labeling requirements, and Material Safety Data Sheets.
Concept Map Answers
Great heat and great pressure transforms sedimentary rocks into metamorphic rocks. Complete melting and cooling transforms sedimentary rocks into igneous rocks. The statement that is not true about the rock cycle is that there is only one way for rocks to go through the rock cycle, as any rock type can become any other type of rock through the various processes in the rock cycle.
Bio-geochemical Cycles
The document is a multiple choice quiz about different types of rocks. Question 1 is about sedimentary rocks, which form from compressed or cemented deposits. Question 2 is about metamorphic rocks, which form from great heat and pressure. Question 3 is about igneous rocks, which form from cooled and hardened magma or lava. Question 4 asks about metamorphic rocks again, stating they often form deep in the earth's crust.
Rock Cycle
Metamorphic rocks form deep within the Earth under conditions of great heat and pressure, partially melting existing rocks like igneous or sedimentary stone. Metamorphic rocks can contain fossils from their original parent rock and form in place from the alteration of other types of rock under high temperature and pressure conditions within the Earth's crust. Common examples include marble.
Metamorphic Rocks
The document discusses different types of sedimentary and metamorphic rocks. It states that sandstone forms from cementation, conglomerate forms from compaction, coal forms from organic material, and limestone forms from organic material or liquid solutions. Sedimentary rocks can contain fossils. Metamorphic rocks form from existing rocks undergoing changes from heat and pressure, and examples given are shale transforming to slate and limestone transforming to marble.
Sedimentary Rocks
This document discusses the three main types of rocks: igneous, sedimentary, and metamorphic. It explains that igneous rocks form from cooled magma and have large crystals if they cool slowly, small crystals if they cool fast, and no crystals if they cool extremely fast. Sedimentary rocks form from pieces of other rocks, once-living things, or liquid solutions that harden over time. Metamorphic rocks form from intense heat or pressure that transforms existing rocks.
Igneous Rocks
The document discusses properties of minerals including that minerals are inorganic, have crystal structures, and can be identified by properties like hardness, streak, cleavage, and crystal form. Halite is identified as having cubic crystal formation and displaying fracture when it breaks.

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?

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).

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
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.
