We certainly could do with some good news at a time when everything seems to be doom and gloom.And Dr. Umar Saif has provided us with the opportunity to celebrate. MIT has named Umar Saif as one of the world’s top young innovators for 2011.
Pakistan has the best talent in the world but the need is to channelize youth and engage them in more constructive activities.
This was stated by Dr Sarwat Rasool, Assistant Professor English Department of Fatima Jinnah Women University (FJWU), Rawalpindi, while addressing a seminar, organised by the university’s Library Administration to observe the International Youth Day here Wednesday. Read more..

Pakistan Tobacco Company Limited (PTC) is one of Pakistan’s most established and structured multinational organization. PTC was established in 1950. It is a subsidiary of British American Tobacco, which has a 63.4% stake in the company. PTC is one of the largest cigarette manufacturing company in Pakistan and has a market share of around 42%. Pakistan Tobacco has initiated a Change Management Program. This program is known as BEST 2000. PTC believes that Total Quality is more than just Product Quality; it is quality of everything they do in business. It means understanding your Consumers, Customers, Stakeholders, and Suppliers. BEST 2000 is serving as the fundamental building block in directing the energies of PTC to achieve its mission statement. The following is the mission statement of PTC: Together we will be the best in everything we do. BEST 2000 was launched in 1997. BEST is helping PTC improve its team building. Further, it provides the means to continuously improve and break the vicious cycles that inhibit improvement activities. Moreover, it assists employees to participate in driving the company forward. The end objective of PTC is to ensure that its team is fully aligned to meet future challenges and well prepared to drive into the next millennium. Pakistan Tobacco has a paid up capital of Rs. 319.367 million. In 1998 the company contributed around Rs. 9.4 billion to the national economy in the form of duties & taxes. The prestigious brands of PTC include Benson & Hedges, John Player Gold Leaf, Capstan, Wills Kings, Wills Gold Flake, Embassy, and Three Castles. Pakistan Tobacco Company diversified its operation by entering into the edible oil market in 1996. Moreover, the company plans to explore the export potential by capitalizing on the opportunities present in the Central Asian countries.
The Higher Education Commission of Pakistan (HEC) provides a number of scholarships to the Pakistani students for the professional & higher education. The scholarships are provided for various Undergraduate, Masters and PhD programmes, both within the country and foreign universities. These scholarships are advertised through major national newspapers and are also available on HEC website.
In its endeavor to develop a class of Highly Qualified and professional Faculty in Pakistan, HEC has launched a series of scholarship programs. Through this series, HEC aims to provide the much needed impetus to the academia by offering indigenous as well as foreign PhD degrees to both faculty members and students. It is well cognizant of the need for customizing the existing scholar ship programs along with providing new opportunities for the pursuit of higher education at home and abroad. With an objective of reinforcing universally accepted principle of excellence in academia, HEC has designed the scholar ship series. Scholar ships are offered not only in reputable disciplines but also in the less recognized but crucial emerging fields.
Several scholarship schemes comprising of indigenous as well as foreign scholarship/fellowships are currently being offered under the program. PhD scholars in all disciplines of strategic national significance are proceeding to various reputable foreign universities/institutions/ research centers by availing these schemes.
The Under Graduate program offers financial assistance to the undergraduate students pursuing or aiming to pursue undergraduate programs of universities/ institutes at home or abroad. Under this program students are offered financial assistance on need as well as talent basis..
The MS program funds postgraduate students for their studies in national universities/ institutes as well as foreign institutions. Under this program students are offered financial assistance for the programs of studies in various disciplines…
The MS leading to M Phil/ PhD program aims to stimulate research and development activities in public sector universities which shall -in turn- generate highly-qualified human resources…
HEC-USAID Need Based Scholarship Program
In pursuance of the Government’s initiative of providing financial relief to meritorious but deprived students, HEC has commenced with the financial assistance/need based scholar ship programs. HEC aims to elevate the socio-economic position of the needy & deserving students by providing access to quality education through need-based scholar ships. Government of Pakistan has also duly acknowledged the financial constraints barring students from acquiring higher education and has thus earmarked substantial funds for the improvement of education sector.
HEC signed an agreement of US 7.33 million in July 2004 with United State Agency for International Development (USAID) to provide grant for scholarship in the field of Agriculture and Business Administration at undergraduate & graduate level.
Orthogonal frequency division multiplexing (OFDM) is becoming the chosen
modulation technique for wireless communications. OFDM can provide large data
rates with sufficient robustness to radio channel impairments. Many research centers
in the world have specialized teams working in the optimization of OFDM for
The purpose of this report is to provide Matlab code to simulate the basic processing
involved in the generation and reception of an OFDM signal in a physical
channel and to provide a description of each of the steps involved.
In an OFDM scheme, a large number of orthogonal, overlapping, narrow band
sub-channels or subcarriers, transmitted in parallel, divide the available transmission
bandwidth. The separation of the subcarriers is theoretically minimal such that
there is a very compact spectral utilization. The attraction of OFDM is mainly due to
how the system handles the multipath interference at the receiver. Multipath generates
two effects: frequency selective fading and intersymbol interference (ISI).
The “flatness” perceived by a narrow-band channel overcomes the former, and
modulating at a very low symbol rate, which makes the symbols much longer than
the channel impulse response, diminishes the latter. Using powerful error correcting
codes together with time and frequency interleaving yields even more robustness
against frequency selective fading, and the insertion of an extra guard interval
between consecutive OFDM symbols can reduce the effects of ISI even more.
Thus, an equalizer in the receiver is not necessary.
There are two main drawbacks with OFDM, the large dynamic range of the
signal (also referred as peak-to average [PAR] ratio) and its sensitivity to frequency
errors. These in turn are the main research topics of OFDM in many research centers
around the world, including the SARL.
A block diagram of the European DVB-T standard is shown in Figure 1.1. Most
of the processes described in this diagram are performed within a digital signal
processor (DSP), but the aforementioned drawbacks occur in the physical channel;
i.e., the output signal of this system. Therefore, it is the purpose of this project to
provide a description of each of the steps involved in the generation of this signal
and the Matlab code for their simulation. We expect that the results obtained can
provide a useful reference material for future projects of the SARL’s team. In other
words, this project will concentrate only in the blocks labeled OFDM, D/A, and
