The document discusses permutations and combinations. It defines a permutation as an ordered arrangement of objects from a set, while a combination is an unordered selection of objects from a set. It provides formulas for calculating the number of permutations P(n,r) and combinations C(n,r) of choosing r objects from a set of n. Examples are given to demonstrate calculating permutations and combinations in different scenarios.
A short presentation to explain the use of permutations and combinations and some examples to illustrate the concepts. This was made as an assignment in which i was to explain the concepts to the class.

Le emissioni dei forni, gli effetti sulla salutecomitatopca
A cura del Coordinamento Lecchese Rifiuti Zero:
a) un forno non fa scomparire i rifiuti ma li trasforma in altro: ceneri, polveri (quelli trattenute dai filtri) ed emissioni gassose (nulla si crea nulla si distrugge)
b) polveri e ceneri vanno smaltite (le polveri pericolosissime in miniere speciali dopo averle vetrificate)
c) per le emissioni gassose (fumi con inquinanti e residui) i filtri non trattengono tutto ma ci sono dei limiti di legge
d) i limiti di legge non sono fissati con la sicurezza che il rispetto di essi non crei danno alla salute ma con il principio BAT (Besty Available Technology), cioè con le emissioni possibili con i migliori sistemi di filtraggio
e) ci sono poi polveri ultrasottili (sotto a 2,5 micron, cioè 2,5 millesimi di mm di diam, vedi raffronto con il capello) che nessun filtro è in grado di trattenere né vengono misurate
f) esistono studi (il più recente uscito a giugno è quello sull'inceneritore di Vercelli) che stanno ad indicare che un inceneritore aumenti i rischi per la salute della popolazione risiedente nell'area di ricaduta dei fumi (vedi tabelle)
g) in particolare oggi si punta il dito sulle micropolveri citate perchè attraversano la membrana cellulare degli alveoli polmonari e vanno in circolo nell'organismo
h) perchè rischiare la salute bruciando di più?

Le conseguenze del teleriscaldamento a rifiuticomitatopca
A cura del Coordinamento Lecchese Rifiuti Zero:
a) chi coinvolgerà il teleriscaldamento, 250 utenze (condomini con riscaldamento centralizzato tra lecco, malgrate e valmadrera)
b) le utenze nella provincia di lecco sono quasi tutte a metano oggi
c) sostituendo il metano con il teleriscaldamento si inquina di più (a parità di calore generato)
d) gli inquinanti verrebbero poi concentrati in una zona ristretta (Valmadrtera, Civate, Galbiate, Suello ecc.)
e) senza spostamenti di costo su tutta la provincia (tramite la tassa rifiuti) il teleriscaldamento costa rispetto al metano parecchio di più
SFO15-202: Towards Multi-Threaded Tiny Code Generator (TCG) in QEMULinaro
SFO15-202: Towards Multi-Threaded Tiny Code Generator (TCG) in QEMU
Speaker: Alex Bennée
Date: September 22, 2015
★ Session Description ★
While QEMU has continued to be optimised for KVM to make use of the growing number of cores on modern systems, TCG emulation has been stuck running in a single thread. This year there is another push to get a workable solution merged upstream. We shall present a review of the challenges that need to be addressed: locking, TLB and cache maintenance and generic solution for the various atomic/exclusive operations. We will discuss previous work that has been done in this field before presenting a design that addresses these requirements. Finally we shall look at the current proposed patches and the design decisions they have taken.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
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.
3. Permutations
A permutation of a set of distinct objects is an ordered
arrangement of these objects.
An ordered arrangement of r elements of a set is
called an r-permutation.
The number of r-permutations of a set with n elements
is denoted by P(n,r).
A = {1,2,3,4} 2-permutations of A include 1,2; 2,1; 1,3; 2,3;
etc…
4. Counting Permutations
Using the product rule we can find P(n,r)
= n*(n-1)*(n-2)* …*(n-r+1)
= n!/(n-r)!
How many 2-permutations are there for the set {1,2,3,4}?
P(4,2)

5. How many Permutations?
Consider four objects {A,B,C,D}
There are 4 choices for the first slot.
There are 3 choices for the second slot.
There are 2 choices for the third slot.
There is 1 choice for the last slot.

9. Permutation Example
Selecting 3 items out of a set of 5
We have 5 choices for the first item.
We have 4 choices for the second item.
We have 2 choices for the third item.
5 x 4 x 3 = 60 Permutations
12. Combinations
An r-combination of elements of a set is an unordered
selection of r element from the set. (i.e., an r-
combination is simply a subset of the set with r
elements).
Let A={1,2,3,4} 3-combinations of A are
{1,2,3}, {1,2,4}, {1,3,4}, {2,3,4}(same as {3,2,4})
The number of r-combinations of a set with n distinct
elements is denoted by C(n,r).
13. Evaluating
In how many ways may 3 items be selected from a set
of 5 without regard to order?
rnC
14. We already know that there 60
permutations of these items.
For each set of three, there are
3! or 6 arrangements.
A B C A C B B A C
B C A C A B C B A
All of these are really the same.
15. Our actual answer is 10.
Consider the set {A,B,C,D,E}
These are the combinations.
A,B,C A,B,D A,B,E A,C,D A,C,E A,D,E B,C,D
B,C,E B,D,E C,D,E

17. How to compute C(n,r)
To find P(n,r), we could first find C(n,r), then order
each subset of r elements to count the number of
different orderings. P(n,r) = C(n,r)P(r,r).
So C(n,r) = P(n,r) / P(r,r)

Let A = {1,2,3}
2-permutations of A are: 1,2 2,1 1,3 3,1 2,3 3,2
6 total. Order is important
2-combinations of A are: {1,2}, {1,3}, {2,3}
3 total. Order is not important
If we counted the number of permutations of each 2-
combination we could figure out P(3,2)!
19. A club has 25 members
How many ways are there to choose four
members of the club to serve on an
executive committee?
Order not important
C(25,4) = 25!/21!4! = 25*24*23*22/4*3*2*1
=25*23*22 = 12,650
How many ways are there to choose a
president, vice president, secretary, and
treasurer of the club?
Order is important
P(25,4) = 25!/21! = 303,600
