Here I have a function in my code that checks the separation of aircraft when called and returns either no separation issues if the predicted paths of all other aircraft (stored in an expandable array) does not intersect with the minimum distance circle around the current one when comparing their relative position and velocity. it doesn't work though and I'm really confused as to what is wrong. I can send the rest of the code through if required void check_separation(ADSBPacket *plane, int planes_info) { int num = -1; for(int i = 0; i < planes_info; i++) { if(plane[planes_info].id == plane[i].id) { num = i; break; } } int original_time = (plane[num].hours * 3600) + (plane[num].minutes * 60); int new_time = (plane[planes_info].hours * 3600) + (plane[planes_info].minutes * 60); int time_change = new_time - original_time; double distance = plane[num].speed * time_change / 1000; double angle = plane[num].heading * M_PI / 180; double east_change = distance * cos(angle); double north_change = distance * sin(angle); plane[planes_info].north = plane[num].north + north_change; plane[planes_info].east = plane[num].east + east_change; plane[planes_info].heading = plane[num].heading; for(int i = 0; i < planes_info; i++) { int original_time = (plane[num].hours * 3600) + (plane[num].minutes * 60); int new_time = (plane[planes_info].hours * 3600) + (plane[planes_info].minutes * 60); int time_change = new_time - original_time; double distance = plane[i].speed * time_change / 1000; double angle = plane[i].heading * M_PI / 180; double east_change = distance * cos(angle); double north_change = distance * sin(angle); plane[planes_info].north = plane[i].north + north_change; plane[planes_info].east = plane[i].east + east_change; plane[planes_info].heading = plane[num].heading; double delta_p_north = plane[planes_info].north - plane[num].north; double delta_p_east = plane[planes_info].east - plane[num].east; double delta_v_north = (plane[planes_info].speed * sin(plane[i].heading)) - (plane[num].speed * sin(plane[i].heading)); double delta_v_east = (plane[planes_info].speed * cos(plane[i].heading)) - (plane[num].speed * cos(plane[i].heading)); double a = (delta_v_east * delta_v_east) + (delta_v_north * delta_v_north); double b = 2 * ((delta_v_north * delta_p_north) + (delta_v_east * delta_p_east)); double separation = 100; double c = (delta_p_north * delta_p_north) + (delta_p_east + delta_p_east) - (separation * separation); if((b * b)- (4 * a * c) >= 0) { printf("Separation issue\n"); break; } } printf("No separation issues\n"); }.

JAVA.Q4 Create a Time class. This class will represent a point in.pdf
JAVA.
Q4: Create a Time class. This class will represent a point in time, such as a departure time. It
should contain 2 constructors, 2 instance variables (hour and minute), and 10 methods (see
below). All methods but toString should be in terms of the 24 hour format. [30 points]
default constructor: Creates a Time object for 12:00AM.
overloaded constructor: Creates a Time object at a specific hour and minute.
getHour(): Returns an integer representing the hour of the Time object.
getMinute(): Returns an integer representing the minute of the Time object.
addHours(...): Updates the object by moving it forward a number of hours.
addMinute(...): Updates the object by moving it forward a number of minutes. (Hint: Be careful
that you don\'t allow minutes to be more than 59.)
addTime(...): Updates the object by moving it forward by the hour and minute from another
Time object.
getCopy(...): Returns a new Time object that has the same hour and minute of the existing Time
object.
isEarlierThan(...): Returns true if this Time object is earlier than another Time object.
isSameTime(...): Returns true if this Time object is the same as another Time object.
isLaterThan(...): Returns true if this Time object is later than another Time object.
toString(): Returns a string representing the Time object. Uses 12 hour AM/PM format and pads
minutes to be two digits. See the sample output for an example.
Q5: Create a Flight class that uses the Plane and Time class. This class will represent a flight
between two airports, using a specific Plane, and departing at a specific Time. It should contain a
constructor, 7 instance variables (plane, flight number, cost, departure, duration, source,
destination), and 9 methods (see below). [25 points]
overloaded constructor: Creates a Flight object that is setup up with a Plane, a flight number, a
cost, a departure Time, a duration time, a source Airport, and a destination Airport.
getPlane(): Returns the Plane that operates this flight.
getNumber(): Returns the flight number.
getCost(): Returns the flight cost.
getDestination(): Returns the destination Airport.
getDeparture(): Returns the departure Time.
getArrival(): Returns a Time object with the arrival time (computed from the departure time and
duration).
getSource(): Returns a Airport object for the departure location.
toOverviewString(): Returns a String representing an overview of the flight. Use NumberFormat
to display the price. See the sample output for an example.
toDetailedString(): Returns a String representing the flight\'s detail information. See the sample
output for an example.
Included below is an overall UML diagram that describes the three classes you will be
constructing. It provides a useful summary of all of the methods you are expected to implement,
and their corresponding types and visibility. Notice that one private method is listed here
(formatDigits in Time) that isn\'t mentioned above. This is a method that was in our solution, you
may not need.

Program to display heart rate and heart beat waveform based on photoplethysmography (PPG). It reads values from a sensor made of photodiode and LED and displays the corresponding heart rate and waveform on an LCD screen
Write a program that obtains the execution time of selection sort, bu.pdf
Write a java program called Question39 that does the following: Gets input for temperature
Utilizing a branching statement: If temperature is 76-100, call method outputHot passing the
temperature input as an argument. If temperature is 0-39, call method outputCold passing the
temperature input as an argument. If temperature is 40 to 75, call method outputJustRight
passing the temperature input as an argument. If temperature is outside these ranges, output
“Temperature outside range” to the screen. Be precise, import modules, include comments,
prologue, etc. as needed.
Solution

Building Real Time Systems on MongoDB Using the Oplog at Stripe
MongoDB's oplog is possibly its most underrated feature. The oplog is vital as the basis on which replication is built, but its value doesn't stop there. Unlike the MySQL binlog, which is poorly documented and not directly exposed to MySQL clients, the oplog is a well-documented, structured format for changes that is query-able through the same mechanisms as your data. This allows many types of powerful, application-driven streaming or transformation. At Stripe, we've used the MongoDB oplog to create PostgresSQL, HBase, and ElasticSearch mirrors of our data. We've built a simple real-time trigger mechanism for detecting new data. And we've even used it to recover data. In this talk, we'll show you how we use the MongoDB oplog, and how you can build powerful reactive streaming data applications on top of it.

Functional C++
Presented at ACCU Oxford (14th September 2015)
Functional C++? As opposed to what — dysfunctional? Well, kind of, yeah. Sure, in C++ the principal unit of composition is called a function, but that doesn't mean it's a functional language. And the idea of restricting mutability of state gets a nod with const, but it's a nod not a hug. And the STL shows influences of functional programming, although it falls short of being compositional. And, yes, sure, C++11 has lambdas, but then again, these days, who doesn't? Lambda calculus was invented in the 1930s.
This talk looks at how to express functional programming ideas in (post)modern C++ in a way that can be considered idiomatic to C++, rather than trying to use the power of overloading and meta-programming to pretend C++ is Haskell or Lisp. In short, immutability beyond const and into shared and persistent data structures, concurrency beyond threading and locks, and thinking about functions as transformations and units of composition rather than actions.

Standing the Test of Time: The Date Provider Pattern
Presented at the April 1, 2017 Tokyo iOS Meetup, in this presentation I talk about how you can test logic that depends on the current date and time by utilizing the "Date Provider" pattern. By simply passing in a Date Provider to the method that needs access to the current date & time, you can easily create a fake/mock object that can be used to test this logic.

In this assignment you will practice creating classes and enumeratio.pdf
In this assignment you will practice creating classes and enumerations in the context of a larger
system. Overall, we are building pieces of an airline flight booking system. The classes that we
are constructing in this assignment will take care of representing the flight data in Java. The final
booking system should be able to searching for flights from a list of commercial airlines (e.g.
American, United, or Delta), and locate various routes between two airports. The output is
somewhat inspired by Google Flights. Don\'t panic! We go will through this system step by step.
For the sake of simplifying the problem, we will make a couple of assumptions: There is only
one timezone. All flights occur in the same day. Already provided for you is a file called
Driver.java. A \"driver\" is a common term for the main program that manages a set of objects,
and manipulates them. It contains the entry point (main) for an entire project. The file you have
been provided contains five static methods that can be called from main. These are testing
methods that will run sample operations on the enumerations and classes you will be
constructing. Initally, they are all commented out. As you implement parts of the assignment,
you should uncomment lines in the test methods, in order to see how your program behaves.
Also attached is the file sample_output.txt. This file contains the sample output for running this
Driver with all of the included tests. You should check the output of your program against the
sample output. Plan to test your files one at a time, for example: make sure to test your Airline
and Airport enumerations before you start on Plane. Don\'t start working on Plane until those two
classes work completely. Time is independent of Airline, Airport, and Plane, but is complicated
enough that you\'ll want the experience of implementing those other questions before you started
it.
Q1: Create an Airline enumeration. This is a datatype that represents airlines in our system.
Include three values: American, United, and Delta. This should be a single file containing the
enum declaration. [2 points]
Q2: Create a smart Airport enumeration. This is a datatype that represents airports in our system,
and has the ability to change from airport code and city name. Include five values: PHX, LAX,
SFO, NRT, and SIN. Also add a static method called getAirportCity. This should be a single file
containing the enum declaration, with the method declaration nested inside. (Hint:
ExampleSmartEnum contains an example of including a method into an enumeration.) [8 points]
getAirportCity(...) will take an Airport enumeration value as a parameter, and return a String
containing the city where that airport is located (e.g., \"Phoenix\", \"Los Angeles\", \"Tokyo\",
\"San Francisco\"). Use a switch statement. Have a default case that returns \"Unknown City\".
Do not implement the switch statement for SIN (Singapore) - we want to test the default case
first.
Q3: Create a Plane clas.

Building Real Time Systems on MongoDB Using the Oplog at Stripe
MongoDB's oplog is possibly its most underrated feature. The oplog is vital as the basis on which replication is built, but its value doesn't stop there. Unlike the MySQL binlog, which is poorly documented and not directly exposed to MySQL clients, the oplog is a well-documented, structured format for changes that is query-able through the same mechanisms as your data. This allows many types of powerful, application-driven streaming or transformation. At Stripe, we've used the MongoDB oplog to create PostgresSQL, HBase, and ElasticSearch mirrors of our data. We've built a simple real-time trigger mechanism for detecting new data. And we've even used it to recover data. In this talk, we'll show you how we use the MongoDB oplog, and how you can build powerful reactive streaming data applications on top of it.

Domain Description for the Lunar Rover Back in July 30th 1971, the c.pdf
Domain Description for the Lunar Rover: Back in July 30th 1971, the crew of Apollo 15
reached the moon surface. The first American astronaut reached the moon along with his team.
But they needed a mean of transportation. Their solution: A lunar buggy called Lunar Rover that
could travel speeds up to 12 km/h. This was an awesome opportunity for astronauts to travel long
distances outside Earth, but there were some technological constraints 45 years ago. The Lunar
Roving Vehicle could had only two pedals and two buttons to control the vehicles systems.
Moon Roover Movement Control: Engineers had to be creative in order to add all the
functionality need for a lunar cruise, so they came up with the following ideas: When the left
pedal was pressed once it accelerates the buggy forward. If accelerating forward and you press
right pedal once, it deaccelerates. To achieve constant forward speed press the right pedal for
more than 3 seconds. If the buggy is at rest and the left pedal is pressed for more than 3 seconds,
it will accelerate backwards. Part 1 Design a state machine to model the Movement Control as
described above. Note: The description above is not complete. Your task includes filling in these
missing details. Make sure to write down any assumptions you make as you develop the state
machine model. Part 2- Camera & Drill (Bonus 4 points): The coolest feature of the buggy
was not its speed but rather the color television camera, the 16-mm camera, and the drill. The
control was packed inside a television control unit. The only problem was that the cameras, and
the lunar rover drill were also controlled by the same control unit. So again engineers used the
two button controller to manipulate all devices: Press the button 1 for five seconds to interact
with the color camera. Press the button 1 for ten seconds to interact with the 16-mm camera.
Press button 1 twice to interact with the drill. Pressing button 2 at any of these modes return to
idle state. In any of the two camera modes, pressing button 1 takes a picture, while if pressed for
5 seconds activates the temporizer (moon selfies). Last inside the drill mode button 1 only acted
as an on off switch. Design a state machine to model the Camera and Drill. Extend the model
you developed for the movement control (2 points). Provide an implementation for this extended
state machine in Java (2 points). Every state should implement an entry action that prints on the
console the current state..
Design a PIC based wearable device that keeps a tract of the activit.pdf
Design a PIC based wearable device that keeps a tract of the activity level of a user. The level of
movement should be classed as: immobile, relatively mobile (walking), highly mobile (HIIT). If
the user has been immobile for a set amount of time, the device should sound an alarm
prompting him to move and only stop when it detects movement. In the mobile state, the device
should count the number of steps taken, and store the number and the length of time in that
activity state. If the number of steps is more than 10, it should be recorded as an exercise session.
The user should be able see a full report of the activities done at the end of the day, including the
details of each session in the mobility states. An additional spec can be to record and display the
time of day the sessions were done..

Exchange Rate Determination Theory OvershootingExchange rate over.pdf
Exchange Rate Determination Theory: Overshooting
Exchange rate overshooting refers to the process in which the movement of the exchange rate
reacts more than the long-term equilibrium state in the short run when a currency volume shock
occurs.
Answer the following questions.
(1) Illustrate and explain the short-term and long-term effects of the increase in the home
country's money supply on the local currency volume, the local interest rate, and the exchange
rate (the Korean won's exchange rate against the dollar) in a two-country model in which both
countries (Korea) and foreign (US) exist.
(2) In the problem above (1), picture the movement of nominal currency volume, price level,
interest rate, exchange rate, and real currency volume over time (i.e., time path) after the
domestic currency volume was moderate..

Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution Class 9 Study Material pdf free download
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Here I have a function in my code that checks the separation of airc.pdf
- 1. Here I have a function in my code that checks the separation of aircraft when called and returns either no separation issues if the predicted paths of all other aircraft (stored in an expandable array) does not intersect with the minimum distance circle around the current one when comparing their relative position and velocity. it doesn't work though and I'm really confused as to what is wrong. I can send the rest of the code through if required void check_separation(ADSBPacket *plane, int planes_info) { int num = -1; for(int i = 0; i < planes_info; i++) { if(plane[planes_info].id == plane[i].id) { num = i; break; } } int original_time = (plane[num].hours * 3600) + (plane[num].minutes * 60); int new_time = (plane[planes_info].hours * 3600) + (plane[planes_info].minutes * 60); int time_change = new_time - original_time; double distance = plane[num].speed * time_change / 1000; double angle = plane[num].heading * M_PI / 180; double east_change = distance * cos(angle); double north_change = distance * sin(angle); plane[planes_info].north = plane[num].north + north_change; plane[planes_info].east = plane[num].east + east_change; plane[planes_info].heading = plane[num].heading; for(int i = 0; i < planes_info; i++) { int original_time = (plane[num].hours * 3600) + (plane[num].minutes * 60); int new_time = (plane[planes_info].hours * 3600) + (plane[planes_info].minutes * 60); int time_change = new_time - original_time; double distance = plane[i].speed * time_change / 1000; double angle = plane[i].heading * M_PI / 180; double east_change = distance * cos(angle); double north_change = distance * sin(angle); plane[planes_info].north = plane[i].north + north_change; plane[planes_info].east = plane[i].east + east_change;
- 2. plane[planes_info].heading = plane[num].heading; double delta_p_north = plane[planes_info].north - plane[num].north; double delta_p_east = plane[planes_info].east - plane[num].east; double delta_v_north = (plane[planes_info].speed * sin(plane[i].heading)) - (plane[num].speed * sin(plane[i].heading)); double delta_v_east = (plane[planes_info].speed * cos(plane[i].heading)) - (plane[num].speed * cos(plane[i].heading)); double a = (delta_v_east * delta_v_east) + (delta_v_north * delta_v_north); double b = 2 * ((delta_v_north * delta_p_north) + (delta_v_east * delta_p_east)); double separation = 100; double c = (delta_p_north * delta_p_north) + (delta_p_east + delta_p_east) - (separation * separation); if((b * b)- (4 * a * c) >= 0) { printf("Separation issuen"); break; } } printf("No separation issuesn"); }
