Threads and Callbacks for Embedded Python
Python is a great choice to be customized plug-ins for existing applications. Extending existing applications with Python program is also practical. For large systems, multi-thread programming is ubiquitous along with asynchronous programming, such as event routing. This presentation focuses on dealing with threads and callbacks while embedding Python in other applications.

Manually determine the configuration of the priority queue (stored as a heap) created
by the following operations. Trace the following logic and define the output:
enqueue(7);
enqueue(17);
enqueue(2);
enqueue(5);
enqueue(22);
enqueue(19);
enqueue(6);
enqueue(11);
enqueue(13);
write the queue contents
dequeue and write front item
enqueue(15);
enqueue(8);
dequeue and write front item
dequeue and write front item
enqueue(24);
enqueue(14);
write the queue contents
Part 2
Then, verify the output by implementing the algorithm by rewriting the priority
queue demonstration program discussed in class. Files needed:
testPQueue.cpp pqType.h heap.cpp
Deliverables
• This cover sheet (with your names on it)
• Driver source code and output for verification program exectution.

CST 280 In-Class Practice – Week 13
Use this page as a worksheet to sketch the progression of the elements up to the first
split for the QuickSort algorithm. Use the middle array element as the split value:
15 34 99 42 11 41 66 23 55 93 48
Next, access the file quickSort.cpp from the course web page. Tailor the program
by entering the array values above in place of the integer values used for an in-class
demonstration. Be sure to adjust the index range to match the size of this array.
Remember that the parameters to the QuickSort algorithm are starting and ending index
values, not the size of the array.
Next, insert code to demonstrate the state of the array after the first split. This should
verify what you did by hand above. Insert the following code at various points within
the partition function to “see” the array at various stages of processing:
for (int i = start; i <= end; i++) // <== ADD
cout << set[i] << ' ';
cout << endl;
Insert the code at these positions:
int partition(int set[], int start, int end)
{
int pivotValue, pivotIndex, mid;
mid = (start + end) / 2;
swap(set[start], set[mid]);
pivotIndex = start;
pivotValue = set[start];
ç HERE
for (int scan = start + 1; scan <= end; scan++)
{
if (set[scan] < pivotValue)
{
pivotIndex++;
swap(set[pivotIndex], set[scan]);
}
ç HERE
}
swap(set[start], set[pivotIndex]);
ç HERE
return pivotIndex;
}
Finally, identify the line that matches what you concluded above.
Deliverables:
Deliver the following for this assignment:
• This work sheet with a sketch of the array first split
• Program source code with required change
• Program output demonstrating array configuration after first split .
C++ Language -- Dynamic Memory -- There are 7 files in this project- a.pdf
C++ Language
** Dynamic Memory **
There are 7 files in this project, and they are down below. And I guess the professor wants us to
modify the set.cpp make sure the numbers are entered by the user to be set dynamically. If you
pay attention to the set.cpp I marked in bold a section that may be needed to be changed. I have
put all the codes down so that you can copy them to your computer to have an idea of how they
work together. Only that Set.cpp must be modified so the number of elements can be set
dynamically during the program's execution. And please can you be more specific about what
line of code needs to be replaced?
Here are the professor's instructions.
** Note: The goal of this assignment is to MODIFY the existing code. **
Implement a dynamically allocated version of the mathematical concept of a 'set'. First, examine
the provided library and driver (in main) for a statically allocated Set class. You may also want
to refresh your mathematical memory of the set concept before proceeding.
Now that you are familiar with how the Set class works, let's make it work better. Currently, the
user is limited to a certain maximum number of elements in their Set. Change it so the number of
elements can be set dynamically during the program's execution.
Extend the driver to test all the ADT's operations.
** Things to Consider **
1. If your set is implemented in dynamic memory:
1a. How do you access the members?
1b. How and when do you re-size the memory?
HERE are the CODE files:.

two iterators for the bounds of the search, first and last. The 3rd parameter is the value being
searched for. if we look inside the find() we might see code like this (ref cplusplus.com): The
description of find () states "The function uses operator== to compare the individual elements to

Develop an inventory management system for an electronics store. The .pdf
Develop an inventory management system for an electronics store. The inventory system should
have the following functionalities .BuildInventory: reada text file containing electronics products
information and store them in an array of pointers .Shownventory display all inventory items
.ShowDefectInventory: display inventory items that are defective Terminate: to save cument
inventory to a text file This lab assignment illustrates the following concepts: -Text file readings
and writings .Arrays of pointers and dynamic memory allocations with new and delete
Inheritance .C++ type casting: static cast Class Design You need at least three classes class
Inventory System: (minimum implementation specified below). This class stores Inyentoryltem
objects (which are in fact Inventory item base class pointers to derived Product objects and
member functions to manipulate those Product objects as shown below. .Private data members
Store Name Store ID ltem List (array of pointers to Inventory Item objects, max of 512) ltem
Count (tracking how many items are currently stored in the array) .Constructors (initialize all
pointers in the array to NULL in addition to what\'s described below .Default constructor: set
data members to 0 (for integers), 0.0 (for float/double), or NULL (for pointers) as appropriate.
Also invoke this function to initialize a seed for the random generator srand (time (NULL), (to
be used later by Product class to genearte random values for Product ID. See Code Helper
section at the end of the lab specs.) .Non-default constructor: taking a string for store name, an
integer for store ID. Call srand as shown above Destructor: de-allocate dynamic memory in the
amay off pointers (up to Item Count elements) .Public member functions: BuildInventory: read a
text file containing Product records (one Product per line), dynamically allocate Product objects
and store the objects in the array ItemList (an array of Inventoryltem pointers). It should also
update Item Count as needed Shownventory: display all Products in the inventory. Output must
be properly formatted and aligned (usingfield with and floating data with 2 digits after decimal
point). Note that if you invoke the Display function using the pointers from the array only Invent
tem (base objec) information will be displayed. Extra work is needed to properly display
Products (derived objects) information ntory: display only defective Products Terminate: iterate
thru the array of pointers to write Product objects in the array to a text file in the same format as
they were read in. You may use a different file name for wniting .mutator cessors for store name,
store id, and item count

Threads and Callbacks for Embedded Python
Python is a great choice to be customized plug-ins for existing applications. Extending existing applications with Python program is also practical. For large systems, multi-thread programming is ubiquitous along with asynchronous programming, such as event routing. This presentation focuses on dealing with threads and callbacks while embedding Python in other applications.

CST 280 In-Class Practice – Week 13
Use this page as a worksheet to sketch the progression of the elements up to the first
split for the QuickSort algorithm. Use the middle array element as the split value:
15 34 99 42 11 41 66 23 55 93 48
Next, access the file quickSort.cpp from the course web page. Tailor the program
by entering the array values above in place of the integer values used for an in-class
demonstration. Be sure to adjust the index range to match the size of this array.
Remember that the parameters to the QuickSort algorithm are starting and ending index
values, not the size of the array.
Next, insert code to demonstrate the state of the array after the first split. This should
verify what you did by hand above. Insert the following code at various points within
the partition function to “see” the array at various stages of processing:
for (int i = start; i <= end; i++) // <== ADD
cout << set[i] << ' ';
cout << endl;
Insert the code at these positions:
int partition(int set[], int start, int end)
{
int pivotValue, pivotIndex, mid;
mid = (start + end) / 2;
swap(set[start], set[mid]);
pivotIndex = start;
pivotValue = set[start];
ç HERE
for (int scan = start + 1; scan <= end; scan++)
{
if (set[scan] < pivotValue)
{
pivotIndex++;
swap(set[pivotIndex], set[scan]);
}
ç HERE
}
swap(set[start], set[pivotIndex]);
ç HERE
return pivotIndex;
}
Finally, identify the line that matches what you concluded above.
Deliverables:
Deliver the following for this assignment:
• This work sheet with a sketch of the array first split
• Program source code with required change
• Program output demonstrating array configuration after first split .
C++ Language -- Dynamic Memory -- There are 7 files in this project- a.pdf
C++ Language
** Dynamic Memory **
There are 7 files in this project, and they are down below. And I guess the professor wants us to
modify the set.cpp make sure the numbers are entered by the user to be set dynamically. If you
pay attention to the set.cpp I marked in bold a section that may be needed to be changed. I have
put all the codes down so that you can copy them to your computer to have an idea of how they
work together. Only that Set.cpp must be modified so the number of elements can be set
dynamically during the program's execution. And please can you be more specific about what
line of code needs to be replaced?
Here are the professor's instructions.
** Note: The goal of this assignment is to MODIFY the existing code. **
Implement a dynamically allocated version of the mathematical concept of a 'set'. First, examine
the provided library and driver (in main) for a statically allocated Set class. You may also want
to refresh your mathematical memory of the set concept before proceeding.
Now that you are familiar with how the Set class works, let's make it work better. Currently, the
user is limited to a certain maximum number of elements in their Set. Change it so the number of
elements can be set dynamically during the program's execution.
Extend the driver to test all the ADT's operations.
** Things to Consider **
1. If your set is implemented in dynamic memory:
1a. How do you access the members?
1b. How and when do you re-size the memory?
HERE are the CODE files:.

Develop an inventory management system for an electronics store. The .pdf
Develop an inventory management system for an electronics store. The inventory system should
have the following functionalities .BuildInventory: reada text file containing electronics products
information and store them in an array of pointers .Shownventory display all inventory items
.ShowDefectInventory: display inventory items that are defective Terminate: to save cument
inventory to a text file This lab assignment illustrates the following concepts: -Text file readings
and writings .Arrays of pointers and dynamic memory allocations with new and delete
Inheritance .C++ type casting: static cast Class Design You need at least three classes class
Inventory System: (minimum implementation specified below). This class stores Inyentoryltem
objects (which are in fact Inventory item base class pointers to derived Product objects and
member functions to manipulate those Product objects as shown below. .Private data members
Store Name Store ID ltem List (array of pointers to Inventory Item objects, max of 512) ltem
Count (tracking how many items are currently stored in the array) .Constructors (initialize all
pointers in the array to NULL in addition to what\'s described below .Default constructor: set
data members to 0 (for integers), 0.0 (for float/double), or NULL (for pointers) as appropriate.
Also invoke this function to initialize a seed for the random generator srand (time (NULL), (to
be used later by Product class to genearte random values for Product ID. See Code Helper
section at the end of the lab specs.) .Non-default constructor: taking a string for store name, an
integer for store ID. Call srand as shown above Destructor: de-allocate dynamic memory in the
amay off pointers (up to Item Count elements) .Public member functions: BuildInventory: read a
text file containing Product records (one Product per line), dynamically allocate Product objects
and store the objects in the array ItemList (an array of Inventoryltem pointers). It should also
update Item Count as needed Shownventory: display all Products in the inventory. Output must
be properly formatted and aligned (usingfield with and floating data with 2 digits after decimal
point). Note that if you invoke the Display function using the pointers from the array only Invent
tem (base objec) information will be displayed. Extra work is needed to properly display
Products (derived objects) information ntory: display only defective Products Terminate: iterate
thru the array of pointers to write Product objects in the array to a text file in the same format as
they were read in. You may use a different file name for wniting .mutator cessors for store name,
store id, and item count

Why are funny channels -funny- (different from other channels)- Becaus.pdf
Why are funny channels "funny" (different from other channels)? Because they allow Na + to
move out of the cell instead of into the cell Because they are the only kind of channel that will
open in response to changes in voltage Because they open in response to membrane
hyperpolarization instead of depolarization Because they aren't really channels at all and actually
block ions from entering cardiac cells All of the above are correct True or False? Increased
sympathetic activity will cause the volume of blood pumped by the ventricles per heartbeat to
decrease. True False.

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.
