Time Value of Money (TVM): Value of the money does not remain same it perishes over a span
of time of it its value go down over a period of time there are various factor one of the major
factor is inflation to compensate inflation and risk interest is given on the lending. So when we
take financial decisions like investment etc. we need to keep in mind the present value of the
inflow of the investment if that money will recovered after certain period of time or if it is series
of the inflow over a certain period of time then present value of all such inflows and also we
need to know what will be the future value of the money after certain period of time or if it is
series of inflow then future value of all such money at end of certain period.
The formula to know the present value of the annuities is PV=P((1-(1+r)^(-n))/r) where P is the
annuity, r is the discount rate and n is the number of period in the same manner formula to know
the future value of the annuity is FV =P *( {(((1+R)^N) - 1) / R}, where ) where P is the annuity,

Decrease in Entropy (S) always occurs when the phase changes from a less ordered
state (such as a gas), to a more ordered state (such as a solid) Decrease in Enthalpy (H) occurs
when a system loses energy. A gas has a high amount of internal energy (think hundreds of ping
pong balls bouncing around in a container), while a solid has the least internal energy (imagine
those same pingpong balls stacked into a lattice). Solid to gas causes an increase in entropy
(more random) and enthalpy (more energy) Solid to liquid still causes both entropy and enthalpy
to increase. Liquid to gas also causes an increase in both entropy and enthalpy for the same
reasons. The reverses of these reactions: Gas to solid, Gas to liquid, and Liquid to solid all have
a decrease in enthalpy and entropy. Example: Gas to Liquid. As a gas cools, it loses energy.
Eventually it will clump together to form a liquid, which decreases its entropy.

The diploid genetic system is more intersting than th monoploid genetic system due to followinf
reasons:Completely dominant allelesIncompletely dominant allelesCodominant allelesIn
complete dominance, the effect of one allele in heterozygous genotype completely masks the
other. The allele that masks the other is said to be dominant while the other which has been
masked is called recessive.Incomplete dominance is a form of inheritance in which one allele
for a specific trait is not completely expressed over its paired allele. This results in a third
phenotype in which the physical traits expressed are a combination of both alleles.Allels that are
masked or hidden by dominant alleles are known as recessive alleles. In some situations, both
alleles are expressed equally.Example : The flower\'s on Mendel\'s pea plant.Example: Pink

Floating point basicsThe core idea of floating-point representatio.pdfinfo235816
Floating point basics
The core idea of floating-point representations (as opposed to fixed point representations as used
by, say, ints), is that a number x is written as m*be where m is a mantissa or fractional part, b is a
base, and e is an exponent. On modern computers the base is almost always 2, and for most
floating-point representations the mantissa will be scaled to be between 1 and b. This is done by
adjusting the exponent, e.g.
1 = 1*20
2 = 1*21
0.375 = 1.5*2-2
etc.
Iam writing a program that does some floating addition that uses bit patterns with shifts applied
to the mantissa and such to obtain the sum of the two floating point numbers. Logically and on
paper I can get this to compute the correct sum.
Code:

Decrease in Entropy (S) always occurs when the phase changes from a less ordered
state (such as a gas), to a more ordered state (such as a solid) Decrease in Enthalpy (H) occurs
when a system loses energy. A gas has a high amount of internal energy (think hundreds of ping
pong balls bouncing around in a container), while a solid has the least internal energy (imagine
those same pingpong balls stacked into a lattice). Solid to gas causes an increase in entropy
(more random) and enthalpy (more energy) Solid to liquid still causes both entropy and enthalpy
to increase. Liquid to gas also causes an increase in both entropy and enthalpy for the same
reasons. The reverses of these reactions: Gas to solid, Gas to liquid, and Liquid to solid all have
a decrease in enthalpy and entropy. Example: Gas to Liquid. As a gas cools, it loses energy.
Eventually it will clump together to form a liquid, which decreases its entropy.

The diploid genetic system is more intersting than th monoploid gene.pdfinfo235816
The diploid genetic system is more intersting than th monoploid genetic system due to followinf
reasons:Completely dominant allelesIncompletely dominant allelesCodominant allelesIn
complete dominance, the effect of one allele in heterozygous genotype completely masks the
other. The allele that masks the other is said to be dominant while the other which has been
masked is called recessive.Incomplete dominance is a form of inheritance in which one allele
for a specific trait is not completely expressed over its paired allele. This results in a third
phenotype in which the physical traits expressed are a combination of both alleles.Allels that are
masked or hidden by dominant alleles are known as recessive alleles. In some situations, both
alleles are expressed equally.Example : The flower\'s on Mendel\'s pea plant.Example: Pink

Floating point basicsThe core idea of floating-point representatio.pdfinfo235816
Floating point basics
The core idea of floating-point representations (as opposed to fixed point representations as used
by, say, ints), is that a number x is written as m*be where m is a mantissa or fractional part, b is a
base, and e is an exponent. On modern computers the base is almost always 2, and for most
floating-point representations the mantissa will be scaled to be between 1 and b. This is done by
adjusting the exponent, e.g.
1 = 1*20
2 = 1*21
0.375 = 1.5*2-2
etc.
Iam writing a program that does some floating addition that uses bit patterns with shifts applied
to the mantissa and such to obtain the sum of the two floating point numbers. Logically and on
paper I can get this to compute the correct sum.
Code:
#include

int isNegative (float f)
{
unsigned int* iptr = (unsigned int*)&f;
return ( ((*iptr) & 0x80000000) ? 1:0);
}
unsigned char getExponent (float f)
{
unsigned int* iptr = (unsigned int*)&f;
return (((*iptr >> 23) & 0xff) - 127);
}
unsigned int getMantissa (float f)
{
unsigned int* iptr = (unsigned int*)&f;
if( *iptr == 0 ) return 0;
return ((*iptr & 0xFFFFFF) | 0x800000 );
}

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
