The tides are caused by the gravitational pull of the moon. This creates two bulges in the Earth's oceans, one on the side facing the moon and one on the opposite side. As the Earth rotates daily and the moon orbits around it monthly, different locations experience high and low tides at different times over the course of approximately 25 hours. This cycle explains why there are two high tides and two low tides each day.

Tides are caused by the gravitational pull of the moon and sun and the rotation of the Earth. The moon's gravity pulls the ocean waters closest to it, creating high tides, while the furthest waters experience low tides. Spring tides occur when the sun, moon, and Earth are aligned, producing the largest difference between high and low tides, while neap tides happen at a right angle and have smaller tidal ranges.
Tides
Tides are the rising and falling of sea levels caused by the combined effects of the gravitational pull of the moon and the sun and the centrifugal force of the Earth's rotation. The moon has the strongest influence due to its closer proximity. This creates bulges in the ocean that result in two high tides and two low tides every 24 hours and 50 minutes. Spring tides occur at new and full moons when the sun, moon, and Earth are aligned, creating higher tides. Neap tides happen when the sun and moon are at right angles, resulting in smaller differences between high and low tides.
Tides (Geology)
Tides are caused by the gravitational interactions of the Earth, Moon, and Sun. The Moon's gravity pulls more strongly on the side of Earth facing the Moon, creating tidal bulges in the ocean. When these bulges are closest to coastal areas, high tide occurs, and when they are furthest away, low tide occurs. The Sun also affects tides. Spring tides occur during a full or new moon when the Sun and Moon are aligned, creating higher high tides and lower low tides. Neap tides occur when the Sun and Moon are at right angles, resulting in weaker tides. Most places experience two high and two low tides each day.
Tides
The document discusses why tides occur on both sides of the Earth, not just the side facing the Moon. During a new moon, the combined gravitational pull of the Moon and Sun causes the Earth to be slightly "squashed" with a bulge facing each celestial body. The far side of the Earth experiences less gravitational pull from the Moon compared to the close side, allowing a bulge to form there as well. The gravity also pulls the Earth and Moon closer together, shifting the center of rotation towards the Sun during a new moon.
Tides
Tides are the periodic rise and fall of ocean water levels caused by the gravitational forces of the moon and sun. The dominant force is the moon, as it is closer to Earth. This causes bulges in the ocean on opposite sides of Earth called high tides, with low tides occurring between them. The periodic rise and fall happens twice each day. Tidal ranges vary depending on the positions of the Earth, moon, and sun, causing spring tides with the largest ranges or neap tides with minimum ranges.
Tides (2)
The moon has a greater tidal effect than the sun. The Bay of Fundy has the greatest tidal range in the world, with tides over 50 feet. A neap tide occurs during the first and third quarter moon phases and produces more moderate tides. A tidal bore is created when an incoming high tide forms a wall of water that moves upriver in some low-lying rivers.
Tides
The document discusses the causes and patterns of ocean tides. Tides are produced by the gravitational forces of the Moon and Sun and the centrifugal force of the Earth-Moon system. These forces create two tidal bulges in the oceans that move around the Earth as it rotates, resulting in two high tides and two low tides each day. Additional factors like the shapes of coastlines and ocean basins can cause the timing and sizes of tides to vary in complex ways.
The Moon and Tides - What causes tides?
Tides are caused by the gravitational interactions between the Earth, moon, and sun. This causes two tidal bulges in the Earth's oceans, with one bulge facing the moon and the other on the opposite side. As the Earth rotates daily and revolves around its axis, different locations experience high and low tides depending on their alignment with the tidal bulges. Specifically, high tides occur when a location is aligned under the moon or opposite the moon, while low tides occur when a location is at a right angle to the tidal bulges.

Tides
Tides are caused by the gravitational forces of the moon and sun interacting with Earth's oceans, which creates two bulges of water that result in two high tides and two low tides each day. The changing positions and distances of the moon and sun relative to Earth cause variations in tide heights and times. Spring tides occur during new and full moons when the sun and moon are aligned, producing the highest tides, while neap tides happen when the sun and moon are at right angles, resulting in lower tides.
Tides
Tides are caused by the differential gravitational forces of the moon and sun on the Earth. This results in two bulges in the ocean on opposite sides of the Earth, creating two high tides and two low tides per day. The highest tides occur during spring tides at new and full moons when the gravitational forces add, while the lowest tides occur during neap tides at half moons when the forces compete. Tides vary in type depending on the moon's declination, with semidiurnal tides occurring most frequently. Local geographic features also influence tide heights and times.
Tides
Tides are caused by the gravitational attraction of the moon and sun on the oceans as well as the centrifugal force from the Earth's rotation. High tides occur where the moon is overhead, while low tides happen 90 degrees away, and both the moon and sun's gravitational pulls contribute to the regular rising and falling of sea levels, though the moon has a greater effect being closer to Earth.
2. Tide Notes
Tides are long period waves in the oceans caused by the gravitational forces of the Sun and Moon. High tide occurs when the crest of the tidal wave reaches a location, while low tide is when the trough arrives. Flood tides bring water inland from the coasts at high tide, while ebb tides carry water back out to sea at low tide. The Moon has a stronger tidal influence than the Sun due to its closer proximity to Earth. This causes two high tides and two low tides each day as the Earth rotates through the tidal bulges created by the Moon's gravity.
Tides notes ppt
The document discusses how the moon's gravitational pull causes Earth's tides. It explains that the moon, being closer to Earth than the sun, has a stronger tidal influence. The moon's gravity causes the oceans to bulge on both the near and far sides of Earth, resulting in two high tides per day. It also describes spring tides with extra high and low tides during new and full moons, and neap tides with less pronounced tides during half moons due to the sun partially offsetting the moon's gravitational pull.
Ocean tides, types and theories
The document discusses ocean tides and their causes. It explains that tides are caused by the gravitational pull of the moon and sun, which create two tidal bulges on Earth. The timing of tides is related to Earth's rotation and the moon's revolution, resulting in a tidal period of about 24 hours and 50 minutes. Tides can be semidiurnal (two high tides and two low tides per day) or diurnal (one of each per day), depending on coastal geography. Spring tides occur during new and full moons when gravitational forces are strongest, while neap tides happen at quarter moons with weaker forces.

The document is a PowerPoint presentation about tides. It introduces tides as the periodic rising and falling of sea levels caused by the gravitational pull of the moon and centrifugal force. There are two types of tides described: spring tides, which occur when the sun and moon are aligned and exert maximum gravitational pull, causing exceptionally high tides; and neap tides, which occur when the sun and moon are at a 90 degree angle, pulling in opposite directions and resulting in very low tides. The document concludes by explaining that tides are caused by the combined gravitational forces of the moon and sun along with the Earth's rotation, and can vary in type and timing in different locations.
Ji Won, Bianca and Isabella
Tides are caused by the gravitational pull of the Moon and, to a lesser extent, the Sun. The Moon's gravity creates bulges in the Earth's oceans that result in high and low tides about every six hours. There are two types of tides: spring tides, which occur during a full moon or new moon and have the largest difference between high and low tides, and neap tides, which occur when the Sun and Moon are at right angles to each other and have a smaller difference between tides.
2 - 3 ocean tides - low & high
Gravity plays a key role in many natural phenomena. It holds planets, stars, and galaxies together through gravitational attraction. On Earth, gravity causes ocean tides as the gravitational pull of the Moon and Sun attract the oceans. This creates two high tides each day as the Moon and Sun's positions change. The highest tides occur during a full moon or new moon when the Moon, Earth, and Sun are aligned, magnifying their gravitational effects in what are called spring tides.
Tides
Tides are the periodic rise and fall of water levels in the sea. They are caused primarily by the gravitational pull of the moon and sun and the centrifugal force due to Earth's rotation. There are two main types of tides: spring tides and neap tides. Spring tides occur twice a month during new and full moons when the sun, Earth, and moon are aligned, resulting in higher high tides and lower low tides. Neap tides occur during the first and third quarters of the moon when the sun and moon form a 90 degree angle, resulting in minimum tide ranges.
Tides
This document defines tides and discusses theories about their generation and types. It introduces the equilibrium and dynamic theories of tides, which explain tides through the gravitational forces of the moon and sun. It describes different types of tides, including spring tides during a full or new moon, neap tides during quarter phases, and rare proxigean spring tides when the moon is closest to Earth. The document also briefly discusses harnessing tidal energy and provides references used.
Tides and generating forces
Tides are caused by the gravitational forces of the moon and sun interacting with the rotation of the Earth. This results in two tidal bulges on opposite sides of the Earth that move around the planet as the Earth rotates. The difference between high tide and low tide is greatest during spring tides when the moon and sun are aligned, and smallest during neap tides when the moon and sun are at right angles to each other. While tidal energy has advantages of being predictable and pollution-free, constructing barrages for tidal power generation is very expensive and can impact the environment.
Tides and its significance
The document discusses tides, which are the regular rise and fall of ocean water levels caused by the gravitational forces of the sun and moon. It describes the different types of tides, including semidiurnal and mixed tides. Spring tides occur during new and full moons when sun and moon forces align to produce higher tides, while neap tides occur during half moons and have lower ranges. The dynamic tidal theory explains how factors like ocean basins, Coriolis forces, and friction influence tidal patterns. Tides are significant as they transport sediments, mix waters in estuaries, and can be harnessed for tidal power generation.
Emily and Nicole
Tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. This causes the ocean levels to rise and fall, creating high tides and low tides approximately every 12 hours on opposite sides of the globe. Spring tides occur during a full moon or new moon and have the highest tidal ranges, while neap tides happen midway between spring tides and have the lowest tidal ranges. Different types of tides are caused by the relative positions of the Earth, moon, and sun.
Tides (Coyle)
Tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. This creates bulges of water on opposite sides of the Earth that result in regular rises and falls of sea level called tides. The moon has a stronger influence than the sun due to its closer proximity. Tides are strongest in coastal areas and weakest in the open ocean. There are typically two high tides and two low tides each day, known as semidiurnal tides, though some locations only experience one of each, called diurnal tides.
theory of oceanography
The document provides information about tides, including what causes tides, the different types of tides, and tidal cycles. It discusses how the gravitational pull of the moon and sun cause tidal bulges in the oceans that result in high and low tides as the earth rotates through these bulges. Most coastal areas experience semi-diurnal tides with two high and two low tides each day, but some locations have diurnal or mixed tides. Spring tides occur during new and full moons when the sun and moon are aligned to produce higher high tides and lower low tides, while neap tides have a smaller tidal range.
Rotation and revolution
The Earth rotates on its axis from West to East, causing day and night. It also revolves around the Sun, causing seasons. The Equator divides the Earth into the Northern and Southern Hemispheres. Rotation and revolution are responsible for different weather patterns and climates in different places over time. Sea breezes occur during the day as warmer air rises over heated land, drawing in cooler air from the sea.
rotation and revolution
The document discusses different types of rotational and orbital motions of objects in space, including the Earth. It explains that the Earth's rotation on its axis causes day and night, while its revolution around the sun over the course of a year leads to seasonal variations due to changes in the sun's angle and day length. Examples of rotation are a top spinning on its axis or the Earth each day, while examples of revolution are the Earth orbiting the sun each year or the moon revolving around the Earth.
Tides & Waves
The document discusses what causes tides and waves. Tides are caused by the gravitational interaction between the Earth, Moon, and Sun, while waves are caused by wind transferring energy to water. Tides and waves can be harnessed to generate renewable tidal power through tidal barrages and tidal stream turbines. However, tides and waves can also cause harmful environmental and ecological impacts if not properly managed.
tides_DrSS.pptx
The document summarizes tides and their causes. Tides are the daily rise and fall of sea levels caused by the gravitational pull of the Moon and Earth's rotation. The Moon's closer proximity to Earth means it has a stronger gravitational pull than the Sun. This pull creates tidal bulges in the oceans on the sides facing and facing away from the Moon. As Earth rotates, different locations experience high and low tides passing through these bulges. Spring tides occur during full and new Moons when the Sun and Moon pull together, creating higher tides. Neap tides happen at half Moons when the Sun and Moon pull at right angles, resulting in lower tides.

The Definition of High Tide and Low Tide
Tides are caused by the gravitational pull of the Moon and Sun on Earth's oceans. The Moon has the strongest effect due to its proximity. The Moon's gravity causes two tidal bulges in the oceans on opposite sides of Earth. As Earth rotates, different locations experience these bulges as either high or low tides about every six hours. The relative positions of the Moon, Earth, and Sun also influence the monthly tidal cycle, with spring tides resulting in higher high tides and lower low tides.
tides.pptx
The Moon's gravitational pull is the primary cause of tides on Earth. The Moon creates bulges in the Earth's oceans on the side facing it and on the opposite side due to having a stronger gravitational attraction being closer. As the Earth rotates, different places experience high and low tides as they come into alignment with these bulges. The Sun also influences tides through its gravitational pull, sometimes reinforcing and other times counteracting the Moon's effects. Spring tides occur during full and new moons when the Sun and Moon are aligned to produce higher tides, while neap tides have lower heights and occur during half moons when their pulls are at right angles.
Nick and Oliver
The tides are caused by the gravitational pull of the moon and sun and the rotation of the Earth. There are two main types of tides: spring tides and neap tides. Spring tides occur during a full moon or new moon when the gravitational pulls of the moon and sun are combined, resulting in very high high tides and low low tides. Neap tides occur during a quarter moon phase when the pulls of the moon and sun are at right angles, resulting in smaller differences between high and low tides. While the moon is the main cause of tides, both the side of Earth closest to the moon and furthest from the moon experience high tides due to the Earth's rotation
010 tides
Tides are caused by the combined effects of the gravitational pull of the Moon and the Sun and the centrifugal force as the Earth rotates. This results in two high tides and two low tides each day, with the tidal ranges varying in a monthly cycle from spring tides with the highest ranges to neap tides with the lowest ranges, depending on the relative positions of the Earth, Moon, and Sun. Tidal patterns differ around the world depending on location.
010 tides
Tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. This causes two high tides and two low tides each day as the Earth rotates. The difference between high and low tides is known as the tidal range, which varies depending on the positions of the moon and sun. Spring tides occur during a full moon or new moon when the sun and moon are aligned, producing the highest tides and greatest tidal range. Neap tides occur during half moons when the sun and moon are at right angles, producing the lowest tides and smallest tidal range.
Sun, Earth, Moon System
This document discusses the relationships between planets, moons, and other celestial bodies. It explains that the Moon orbits the Earth and is considered our natural satellite. A satellite revolves around a planet. Lunar eclipses occur when the Moon passes behind Earth into its shadow, while solar eclipses happen when the Moon passes between Earth and the Sun. The Moon's phases are caused by varying amounts of sunlight reflecting off its surface due to its orbit around Earth. Tides are also influenced by the Moon's gravity, with high and low tides occurring regularly due to the positions of the Moon and Sun relative to Earth.
Tides by rockredstar
Tides are caused by the gravitational attraction of the moon and sun to the earth. Lunar tides occur every 12.5 hours and cause the two daily high tides and low tides. Solar tides also occur daily but are smaller. Spring tides during a full or new moon produce the highest tides when the sun and moon are aligned. Neap tides during a first or third quarter moon have the lowest tides when the sun and moon are at right angles. Perigean tides occur when a spring tide coincides with the moon's closest orbit to earth. Coastlines typically experience semi-diurnal tides with two high and two low tides each day, while some enclosed basins have

The document discusses how seawater becomes salty. Most of the salt in the oceans comes from minerals washed into rivers from land by rain. As water evaporates from the ocean surface, it leaves the salt behind, concentrating the salinity over time. While some salt comes from underwater volcanic vents and eroding seabeds, the primary source is erosion of land surfaces by rain and rivers. Salinity levels vary globally depending on factors like ice melt and evaporation rates.
Marine Tide Notes
Tides are long period waves in the oceans caused by gravitational forces from the Sun and Moon. High tide occurs when the crest of the tidal wave reaches a location, while low tide is when the trough arrives. Tides create flood currents during incoming tides and ebb currents during outgoing tides, with the strongest currents occurring near high and low tides. The Moon has a greater influence on tides than the Sun due to its closer proximity to Earth. This causes coastal areas to experience two high tides and two low tides every 24 hours and 50 minutes.
Our moon
The Moon is the Earth's only natural satellite. It revolves around the Earth in about 28 days, keeping the same face always pointed towards the Earth. The Moon's surface is marked by impact craters caused by meteorites colliding with its surface over time. The Moon is smaller than the Earth and influences the tides on our planet through its gravitational pull.

The document discusses the rotation and revolution of Earth and the Moon. It explains that Earth rotates on its axis every 24 hours, causing day and night. It revolves around the Sun in an elliptical orbit over the course of a year. The Moon revolves around Earth, causing the phases of the Moon as it reflects sunlight. The positions of Earth, Moon, and Sun cause solar and lunar eclipses periodically.

The document discusses tides and provides information about their causes and patterns. Tides are periodic changes in ocean water levels caused by the gravitational pull of the moon and sun. Most places experience two high and two low tides daily (semi-diurnal) but some have only one of each (diurnal). Tides were discovered over 300 years ago by Isaac Newton, who developed the theory that all objects exert gravitational pulls on each other. The document defines and compares spring tides, which occur during full and new moons, and neap tides, which happen during quarter moons and have smaller differences between high and low water levels.
My Genius Hour Project
Tides are periodic changes in the water level of oceans, gulfs and bays caused by the gravitational pull of the moon and sun. Most places experience two high tides and two low tides daily, called semi-diurnal tides, though some have only one per day, called diurnal tides. Tides were discovered over 300 years ago by Isaac Newton, who developed the Equilibrium Theory of Tides to explain how every object exerts a gravitational pull on every other object. There are two main types of tides: spring tides, which occur during full and new moons and have more extreme high and low tides, and neap tides, which happen during half moons and have the
Tides
The document discusses tides and their causes. Tides are caused by the gravitational pull of the moon and sun, which pulls the water towards them. This causes two high tides each day on opposite sides of the Earth. The moon has a greater effect on tides due to its closer proximity. Tides can affect fishermen, fish, animals in tide pools, and require some buildings to be elevated. Tidal energy generation uses turbines in the water powered by tidal flows. Spring tides produce higher high tides when the sun and moon effects are aligned, while neap tides have lower high tides when their effects oppose each other. Places can experience diurnal or semidiurnal tides depending on whether the location
Tides & tidal waves
In this presentation, one will find more elaborative and detailed information on the topic of TIDES with full depth knowledge about its various aspects including the forces that act on it, how & when they act on it with illustrative images.
Tides
Tides are the periodic rise and fall of ocean water levels caused by the gravitational forces of the moon and sun. The moon has the strongest effect due to its closer proximity to Earth. This causes bulges in the ocean on opposite sides of Earth called high tides, with low tides occurring between them. The tidal range, or difference between high and low tide, varies depending on the alignment of the sun, Earth, and moon, causing either spring tides with a large range or neap tides with a minimum range.
Ocean motion
1. Waves transfer energy through water in the ocean. Individual water particles move in circles as a wave passes by rather than moving forward with the wave.
2. Key characteristics of waves include the crest (highest point), trough (lowest point), wavelength (distance between crests), and wave height (distance between crest and trough). Wavelength determines wave speed and how deep the wave disturbs the water.
3. As waves approach shore they slow down and steepen, eventually collapsing in breakers where the crest curls over. Tides are caused by gravitational attraction of the Earth, Moon, and Sun, and vary in daily and monthly cycles.

Lab 6: Tides and Coastal processes
Goals:
1. Understand what causes tides.
2. Understand how deep-ocean waves change and break when they reach a coastline.
3. Understand how shoreline transport of sediment occurs and how it is affected by human activities.
Tides
Tides are actually waves that move through the oceans and large lakes. In the oceans, they have periods of several hours and wavelengths of 1000s of kilometers. Depending on the wave period that dominates in different parts of the world, some places have only one high and one low tide a day (diurnal tides), whereas others have two high (about equal to each other) and two low tides (also about equal to each other) known as semidiurnal. A third type is mixed tides with two highs and two lows a day with different heights, (a high high, a low high, a high low and a low low). California, as the rest of the west coast has mixed tides.
The gravitational pull of the Sun and the Moon causes tides on Earth. The gravitational influence of an object is directly related to its mass and its distance from another object. So even though the Sun has much more mass than the Moon, it is over 380 times farther away from the Earth than the Moon. Therefore, our little Moon wins out and has the most influence on the tides on Earth.
As the Earth spins about its axis, centrifugal force keeps water balanced on all sides of the planet. However, the Moon's gravitational forces disrupt this balance by pulling the water towards the Moon. A double "bulge" is formed—one side pulling toward the Moon and the opposite side pulling away from it, just like swinging a water balloon causes it to stretch both toward AND away from your hand. The areas where the bulging occurs experience high tides.
Tides are predictable, but their periods do not coincide with the 24 hour Earth day. The Moon takes about 24 hours and 50 minutes to line up again exactly with the same point on the Earth. Therefore, the timing of the tides shifts almost an hour a day. Because the relative positions of the Sun, Earth and Moon change over the course a day, a month and a year, the absolute heights of diurnal, semidiurnal and mixed tides vary over these periods. For example, even within the same ~25 hour period, the heights of the semidiurnal tides are not exactly the same, although they are close. Even more significant changes are seen over a monthly cycle, with higher-than-normalspring tides (not named for the season but because the water "springs" higher than normal) and the lower-than-normalneap tides.

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.

Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

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).

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.

Mouse mischief tides
- 2. What Are Tides? Have you spent a day on an ocean beach and noticed that the water comes in closer or goes out farther during the day? Have you wondered why the water does this?
- 3. What Are Tides? The water rises and falls because of the tides. There are two high tides and two low tides in a little less than 25 hours—just a little more than one full day.
- 4. You arrive at the beach at 9:00 A.M. You lay a towel on the sand, and then you run 30 steps to reach the water’s edge. By 3:00 P.M., the water has almost reached your towel. What do you think happened? The waves got bigger. Rainwater filled up the sea. The tide came in.
- 5. What Causes Tides? Basically, tides are caused by the moon’s gravity. The moon pulls water on the Earth toward itself, causing a bulge on the side of the Earth near the moon. Water bulges on the side of the Earth nearest the moon. But there’s more to it than that.
- 6. What Else Is Happening? The Earth rotates one full turn in 24 hours, but the bulge of water stays on the side of the Earth facing the moon. The bulge stays in place as the Earth moves under it. The moon also orbits around the Earth about every 27 to 28 days. Earth rotates this way. Moon orbits this way.
- 7. Draw an arrow to show which way the Earth rotates, then draw another arrow to show which way the moon orbits around the Earth.
- 8. How Else Does the Moon Affect the Tides? Earlier we said that it takes almost 25 hours for a cycle of tides to finish. But why is this so, if a day is only 24 hours long? The moon is a little farther East every day. This also means that the water bulge caused by the moon’s gravity arrives a little later every day.
- 9. Moon and Earth Move The Earth must rotate a little more before any one place is as close to the moon as it was the day before. That’s why it takes more than one full day for the tides to finish a full cycle. Noon on Tuesday Earth’s North Pole Moon orbits this way Noon on Monday
- 10. On Saturday at the beach, the water is highest at 11:15 A.M. On Sunday, the water is highest at 11:55 A.M. Why does the tide come in later? It’s really the same time, but your watch is fast, so you think it’s earlier. The moon has moved a little, so the beach is closest to the moon at a later time. The tide always comes in later on Sunday.
- 11. Why Are There Two High Tides and Two Low Tides? There are really two bulges of water on the Earth. One bulge is toward the moon. The other bulge is on the far side of Earth from the moon. Why? Have you ever ridden a carousel? Did you feel your body pulled to the outside as the carousel spun? The same thing happens to water on Earth.
- 12. The Earth and Moon Really Orbit Each Other We say that the moon orbits the Earth, but in fact, the Earth moves a little too, because of the moon’s gravity. Common center of gravity The Earth and moon both orbit a common point.
- 13. Some Water is Spun into the Opposite Direction from the Moon As the Earth follows the moon’s gravity, some water on the Earth is pulled in the opposite direction. Earth’s movement pulls other water in the opposite Moon’s gravity direction. pulls some water toward the moon. Where the water bulges are, the tide is high. Between the bulges, the tide is low. That’s why there are two high tides and two low tides each day.
- 14. You’re on the beach at midnight. The moon is right overhead. Will the tide be… …high, because the moon is as close as it can be to where you are? …between low and high, because the tide rises and sets with the Sun? …low, because the tide is caused by the Sun’s gravity?
- 15. Draw where you would expect the bulges of water that cause high tides to be.
- 16. The sun is rising, but you can still see the moon in the western sky. Would you expect the tide to be going out? Yes No
