I managed to do this in terms of polar coordinates. How would one solve this using the fact that T(z) = z^2? (2) Consider the map T: D D, where D is the unit disk in the plane, given by T(r cos theta, r sin theta) = (r^2 cos 2theta,r2 sin 2theta), Using complex notation, z = x + iy, the map T can be written as T(z) = z^2, Show that the Jacobian determinant of T vanish only at the origin. Thus, away from the origin, T is locally one-to-one. However, show that T is not globally one-to- one on 2 minus the origin. Solution T(z) = T(rcost, rsint) Consider z^2 = (rcost, rsint).(rcost,rsint) = r^2cos^2t+r^2sin^2t = r^2 = (x^2+y^2) where x =rcost and y =rsint Thus T(z) = z^2 T(z) = z^2 =0 only when r=0 or at the origin. As T(z) = z^2, T(-z) = (-z)^2 =z^2 Thus z and -z have the same image under T. T is not one to one..

i need help with fractions like adding and subtracting fractions with unlike denominators
Solution
Let a/b and c/d be tho fractions to be added or subtracted. Deno. b & d are unlike.
Let us make b*d as common den. for two fractions.
So, a/b = (a*d)/(b*d) ......(1)
and c/d = (c*b)/(b*d)........(2)
For adding, we can now add numerators with common denominator
i.e. we get (a*d + c*b)/(b*d)
For example, we want to add 1/2 and 2/3
i.e. 1/2 +2/3
=> 3/6 +4/6
=>7/6
similar is subtraction.
1/2 - 2/3 = 3/6 - 4/6 = -1/6
Hope it is clear..

Introduction :
All SAS jobs are a sequence of SAS steps, which are
made up of instructions, which are called SAS
statements. There are only two kinds of SAS steps:
DATA steps are used to read, edit, and transform data
(raw data or SAS data files), to prepare SAS data sets,
PROC steps are ready-to-use procedures which
analyze or process SAS data sets. In general, data
must be in a SAS data file before they can be
processed by SAS procedures.
Without going into the details at this time, here is a
skeletal example of a SAS job:
DATA STUDENTS;
INPUT NAME $ 1-14 SEX $ 15

DATALINES;

PROC SORT DATA=STUDENTS;
BY SECTION DESCENDING GRADE;
PROC PRINT DATA=STUDENTS;
BY SECTION;
RUN
There are two kinds of SAS data sets: SAS data files (or tables), and SAS data views. A SAS
data file contains: the descriptor portion, which provides SAS procedures and some DATA step
statements with descriptive information (data set attributes and variable attributes) about the data
, and the data portion, a rectangular structure containing the data values, with rows (customarily
called observations), and columns (customarily called variables); and which is passed to most
procedures, observation by observation. A SAS catalog is a type of SAS file which stores many
different types of information used by the SAS System. All SAS files reside in a SAS data
library. The SAS System processes the program in two steps: (1) it compiles the program, and
(2) it executes the program. When the program is compiled, a program data vector (PDV) is
constructed for each DATA step. It is an area of memory which includes all variables which are
referenced either explicitly or implicitly in the DATA step. At execution time, the PDV is the
location where the current working values are stored as they are processed by the DATA step.
Variables are added to the PDV sequentially as they are encountered during parsing and
interpretation of SAS source statements. Each step (DATA or PROC) is compiled and executed
separately, in sequence. And at execution time within each DATA step, each observation is
processed iteratively through all of the SAS programming statements of the DATA step. SAS
procedures (PROCs) are programs that are designed to perform specific data processing and
analysis tasks on SAS data sets. Base/SAS procedures fall into the following categories: SAS

It is about University of Virginia designed by Thomas Jefferson.
I must write about Thomas Jefferson’s vision for the University of Virginia, describe the design
of the campus and types of buildings included in his plan, sources of inspiration, and his vision
for the academic community.
I must write it in three parts.
Part One: Description of the plan (one paragraph) A) Describe the characteristics of Jefferson’s
plan for the University of Virginia, including the types of buildings he included, and their
purposes. This should be presented in a written paragraph, NOT a bullet point list.
Part Two: Sources of inspiration (one paragraph) Briefly explain a) what individuals and b) what
other buildings or places contributed to Jefferson’s design.
Part Three: Jefferson’s Academic Village (one paragraph) Briefly explain how the overall design
of the university and the style of the buildings express Jefferson’s ideas about an “Academical
Village.”
Thanks in advance.
Any help would be appreciated. I want to make sure I write a quality paper and I really need help
with how to organize and write it out.
Solution
part one: The plan of the academical village, the first promoted to the university board parallel
rows and connected by colonnades around a central lawn. this plan was an extreme departure
from the classic American collegiates campus.A domed building based on sixteenth- century
Italian Andean palladio\'s drawings of the ancient roman pantheon. Heeding the two
architecture\'s advice jefferson placed the university library which he called the Rotunda,at the
head of composition.
part two: The design of the academical village reveals a successful application of jefferson\'s
multifeted architectural and personal interest to a collegiate setting. An innovative echo of french
hospital design and antique Roman temples, jefferson\'s university plan served as amodel for
subsequent college campus across country.when designing the university of virginia, jefferson
also incorporated his intrest in Roman architecture, each of the pavillion recalls structure
illustrated in palladio\'s FOUR BOOKS OF ARCHITECTURE and Rotunda at the head of the
village is in essence, aminiature pantheon.
part three: He wish to establish in the upper and healthier country and more centrally for the state
an university on aplan so board and liberal and modern as to be worth patronizing with the public
suppot and the temptation to the youth of other state to come and drink of the cupof knowledge
and faternize with us.These ideas found this way into jefferson\'s designs for his mountain top
residence of monticello,his retreat at poplar forest and later for his university. The notion of a
universityas village for instance possibly was inspired by jeffersons reading of treaties describing
how disciples noted Greek philosophers set up huts around their master\'s dwelling in a village

Rio Claro, Inc. (RCI) is in the business of transporting cargo between ports in California and
Washington. Its fleet includes a small dry-cargo vessel, theMaracas. The Maracas is 25 years old
and badly in need of an overhaul.
It is March 2016, and Michael John, the finance director, has just been presented with a proposal
that would require the one-time expenditures shown below in Table 1. If the proposal is
accepted, these expenditures will be made in the next few days. Mr. John believes that all these
outlays could be depreciated for tax purposes in the seven-year MACRS class (see Table 2 below
for rates). Overhaul of theMaracas will begin as soon as the expenditures in Table1 are made, but
the vessel will be out of service for several months. The overhauled vessel would resume
commercial service in one year. RCI’s chief engineer’s estimates of the post-overhaul operating
costs are in Table 3.
In addition to the overhaul described above, the chief engineer suggests installation of a brand-
new engine and control system. Installation of this new engine would cost an extra $600,000
(This additional outlay would also qualify for tax depreciation in the seven-year MACRS class.).
However, if the additional equipment is installed, it would result in reduced fuel, labor, and
maintenance costs as shown in Table 4.
The operating cost estimates in Tables 3 and 4 are current for March 2016. However, these costs
will increase with inflation, which is forecasted at 1.25% a year. Depreciation and operating
costs attributable to the overhaul of theMaracaswill begin one year after the vessel is put back
into commercial service. The revenues from operating the vessel will be the same for both types
of overhaul.
Even with the proposed overhaul, the Maracas cannot continue forever. After the overhaul, its
remaining useful life is estimated to be only 12 years. Its salvage value when finally taken out of
service will be trivial. Thus, Mr. John feels it is unwise to proceed without also considering the
purchase of a new vessel. Racette & Sons (R&S), a Colorado shipyard, has approached RCI with
a design incorporating a Kort nozzle, extensively automated navigation and power control
systems, and much more comfortable accommodations for the crew. R&S is offering the new
vessel for a fixed price of $3,000,000, payable half immediately and half on delivery in one year.
Estimated annual operating costs of the new vessel are in Table 5. The operating cost estimates
in the table are current for March 2016, but will increase with inflation.
The crew would require additional training to handle the new vessel’s more complex and
sophisticated equipment. Training would result in a one-time cost of $50,000 payable one year
following delivery of the new vessel. This cost is tax deductib.
I know that real numbers consist of the natural or counting numbers,.pdf
I know that real numbers consist of the natural or counting numbers, whole numbers, integers,
rational numbers and irrational numbers. But what about imaginary number i. And is it possible
that i can use an imaginary number for a real number.
Solution
There are two types of numbers 1.Real 2.Imaginary So we cannot use real as
imaginary because they belong to different categories..

I hope i did all of that correctly.Can someone check my math o.pdf
I hope i did all of that correctly.
Can someone check my math on the derivatives...and is there anyway to simplify them?
Now i must show that the population P reaches half the limiting population M, when P\'\'=0 [ie
when P\'\'=0 P=M/2]
what should i do here?
Solution
You could have tried it in another way.
1/P = (1/M) + ((1/P0) - (1/M)) eMR(t0-t)
Now differentiating it woul;d be easier.
I hope someone can help me , I need to write a ten page paper on Pro.pdf
I hope someone can help me , I need to write a ten page paper on Probability by 215-2012. Is
there any out there that can help me with this problem?
Solution
Probability is ordinarily used to describe an attitude of mind towards some
proposition of whose truth we are not certain.[1] The proposition of interest is usually of the
form \"Will a specific event occur?\" The attitude of mind is of the form \"How certain are we
that the event will occur?\" The certainty we adopt can be described in terms of a numerical
measure and this number, between 0 and 1, we call probability.[2] The higher the probability of
an event, the more certain we are that the event will occur. Thus, probability in an applied sense
is a measure of the likeliness that a (random) event will occur. The concept has been given an
axiomatic mathematical derivation in probability theory, which is used widely in such areas of
study as mathematics, statistics, finance, gambling, science, artificial intelligence/machine
learning and philosophy to, for example, draw inferences about the likeliness of events.
Probability is used to describe the underlying mechanics and regularities of complex systems.
The word probability does not have a singular direct definition for practical application. In fact,
there are several broad categories of probability interpretations, whose adherents possess
different (and sometimes conflicting) views about the fundamental nature of probability. For
example: Frequentists talk about probabilities only when dealing with experiments that are
random and well-defined. The probability of a random event denotes the relative frequency of
occurrence of an experiment\'s outcome, when repeating the experiment. Frequentists consider
probability to be the relative frequency \"in the long run\" of outcomes.[3] Subjectivists assign
numbers per subjective probability, i.e., as a degree of belief.[4] Bayesians include expert
knowledge as well as experimental data to produce probabilities. The expert knowledge is
represented by a prior probability distribution. The data is incorporated in a likelihood function.
The product of the prior and the likelihood, normalized, results in a posterior probability
distribution that incorporates all the information known to date. The scientific study of
probability is a modern development. Gambling shows that there has been an interest in
quantifying the ideas of probability for millennia, but exact mathematical descriptions arose
much later. There are reasons of course, for the slow development of the mathematics of
probability. Whereas games of chance provided the impetus for the mathematical study of
probability, fundamental issues are still obscured by the superstitions of gamblers.[8] According
to Richard Jeffrey, \"Before the middle of the seventeenth century, the term \'probable\' (Latin
probabilis) meant approvable, and was applied in that sense, univocally, to opinion and to action.
A probable action or opinion was one such .

Why do you say that Project Management is the best method of implementing
change? Although change occurs continuously in the world and in our daily lives it is rarely
implemented that way in organisations but rather as a series of steps; a ladder of change. A new
piece of legislation, market imperatives, management initiatives and new technology create
projects that need to be managed, often across departmental or disciplinary lines. Project
Management is a methodology and a discipline which can bring significant benefits to
organisations by:- Ensuring limited resources are used on the right projects Harnessing the
energy of staff in achieving beneficial change Managing complex changes in an organised way
Assessing risks, defining goals and key success areas and setting quality objectives. However,
every organisation has finite resources and, therefore, a limit to the number of projects it can
initiate and control. Pushing too many projects through a resource limited organisation causes
gridlock and stress. Managing the project portfolio efficiently is a fundamental principle of good
project management. Because most projects involve new ideas and learning (even a project to
build houses or flats may involve new materials or unusual soil conditions or there may be new
initiative for tenant selection or co-ownership schemes) project management has evolved a
discipline to manage the new and unusual. Its objective is to: define the project reduce it to a set
of manageable tasks obtain appropriate and necessary resources build a team or teams to perform
the project work plan the work and allocate the resources to the tasks monitor and control the
work report progress to senior management and/or the project sponsor close down the project
when completed review it to ensure the lessons are learnt and widely understood. It is this
structured approach that makes project management the best method for change management.
What is a project? A project is generally defined as a programme of work to bring about a
beneficial change and which has:- a start and an end a multi-disciplinary team brought together
for the project constraints of cost, time and quality a scope of work that is unique and involves
uncertainty Examples of a project:- The development and introduction of a new services The
development of a management information system The introduction of an improvement to an
existing process Setting up a new care initiative The creation of a large tender or the preparation
of a response to it. The production of a new customer newsletter, catal.

Wikis are web-based tools that make it easy for users to add, remove, and change online content.
employees at companies such as Intel, Motorola, IBM, and Sony use them for a host of task,
from setting internal meeting agendas to posting documents related to new products.
Many companies rely on wikis to engage customers in ongoing discussions about products.
wikis ABC and CBS, created fan wikis that let viewers interact with each other as they unraveled
mysteries from such shows as Lost and CSI: Crime Scene Investigation. You would like to
implement wikis at your new company, The Consulting Edge, a small computer consulting
company catering to mid- and large-sized businesses. Answer the following questions:
*How can a wiki help you attract customers and grow your business?
*HOw can a wiki help your partners and employees?
*What ethical and security concerns would you have with the wiki?
*What could you do to minimize these concerns?
Solution
1.
2.
A wiki is a Web site that enables users to collect team knowledge, plan events, or work on
projects together. People can easily add new content or edit existing content. Wikis continue to
evolve as people add and revise information. Although a version history is collected, and the
history is organized in chronological order, the versions aren\'t displayed in journal style in the
default view of a wiki.Your team may want to use a wiki to build a collective body of knowledge
or to facilitate planning, such as for a team project, a publication, or a conference.For example, a
company marketing team uses a wiki to help newly hired staff members get started quickly. As
team members run across additional resources or have additional advice to relay, they add the
links and information.

I have heard multiple times that a consistent definition of liquidit.pdf
I have heard multiple times that a consistent definition of liquidity does not exist. The two
wikipedia articles describing liquidity (Market liquidity and accounting liquidity) lack a
discussion of this apparent problem within economics. Could someone perhaps provide a
reference to a discussion of the problem of defining liquidity and maybe provide a brief
summary of the issue?
Solution
Etymology and Introduction
As a concept to measure the interchangeability of assets and money, liquidity is a new word. It
first appears in 1923 in a use by Hawtrey (The Oxford English Dictionary (1989)). The
underlying idea however is much older. Menger (1892) calls a good more or less saleable
according to the facility to which it can be disposed of at current purchasing prices with less or
more diminution. He is talking about the origin of money, and not the disposition of financial
assets, but this concept of saleability is very much like the modern concept of liquidity. This
sense of saleability goes back at least as far as Jehan Palsgrave\'s usage in 1530 (The Oxford
English Dictionary (1989)). Although the absence of liquidity is now commonly referred to as
\"illiquidity\", Marschak (1938) offers \"frozen\" as an alternative that did not catch on.
Hicks (1962) says that the use of the word liquidity in a financial sense was popularized by
Keynes and the Macmillan Report in the 1930\'s (Macmillan Committee of HMSO (1931)). In
The General Theory, Keynes says that liquidity justifies money trading at a premium over bills
or bonds and causes the existence of an interest rate. Hicks teases from Keynes\' Treaty on
Money (Keynes (1930)) that one calls an asset more liquid than another if it is \"more certainly
realizable at short notice without loss.\"
This quote is more ambiguous than it may seem at first glance. Hicks offers several
interpretations. The first, which he flatly rejects, define liquidity as the difference between the
price the owner carries on his books for an asset and the price they could sell it for on the market.
The second, is an interpretation of marketability. Hicks defines a security as marketable if it is
sold just as well after negotiation, search and advertising as it is without it. That is, we can
compare the liquidity of two assets by the relative sacrifice one makes from a rapid sale. He
claims this interpretation is \"more appealing\" but still not what Keynes meant. He understands
Keynes\'s definition of liquidity to require perfect marketability, but even perfectly marketable
assets can be more or less liquid. The difference here is in the moments of the asset\'s price.
Among marketable financial assets, we can regard them as more or less liquid by using a utility
function to manage the trade-offs between maximizing the desirable odd moments (e.g., positive
mean and skew) and minimizing undesirable even moments (e.g., variance and leptokurtosis) of
asset returns.
Definitions of Liquidity
A treatment of market liquidity is crit.

(11,12,12,9,8.5,9.5,8.5,11,10,9,16,12,10,12,14). Count the total number of observations you
have, and label this number N. Then create another set of data starting from one and increasing
by one until you reach N (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15). This set of data is called a time

series as an independent variable. What are the results and any conclusions that can be reached
by the results?

variable(y)=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 The equation for a straight line is usually written
as: Y = bX + a where b = slope of the line = (Y2 - Y1) / (X2 - X1) = “the rise” divided by “the

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.

I managed to do this in terms of polar coordinates. How would one so.pdf
- 1. I managed to do this in terms of polar coordinates. How would one solve this using the fact that T(z) = z^2? (2) Consider the map T: D D, where D is the unit disk in the plane, given by T(r cos theta, r sin theta) = (r^2 cos 2theta,r2 sin 2theta), Using complex notation, z = x + iy, the map T can be written as T(z) = z^2, Show that the Jacobian determinant of T vanish only at the origin. Thus, away from the origin, T is locally one-to-one. However, show that T is not globally one-to- one on 2 minus the origin. Solution T(z) = T(rcost, rsint) Consider z^2 = (rcost, rsint).(rcost,rsint) = r^2cos^2t+r^2sin^2t = r^2 = (x^2+y^2) where x =rcost and y =rsint Thus T(z) = z^2 T(z) = z^2 =0 only when r=0 or at the origin. As T(z) = z^2, T(-z) = (-z)^2 =z^2 Thus z and -z have the same image under T. T is not one to one.
