Islamabad and Allies must win hearts and minds of flood victims with humane aid delivery

Even though the flood water is receding from Southern parts of Pakistan, the majority poor in Pakistan, in the North and elsewhere, are still suffering from the month long flood’s devastation. To redress this situation and to play the offensive strategically, the United States has pushed through a large aid package designed to re-acquaint the mostly poor people of Pakistani to the idea that the U.S. is out for something other than its immediate short-term interests. That narrative—the U.S. is Pakistan’s partner in its social and economic developmental goals– now seems to have been undercut by video-images that show inadequate, incompetent aid delivery and the unruly, violent fights that seem to spontaneously burst in flames in over-populated, shoddily built relief camps each time an aid delivery goes awry. These images register a violent state of nature, where animalistic dominance prevails over long-observed culturally sensitive tribal honor. The losers of these vicious fights ramble away, their dignity lost

President Asif Ali Zardari’s Row With David Cameron Meant to Shore Up Support With the Military and Provincial Governors

By now, no doubt, President Asif Ali Zardari and Prime Minister David Cameron have hashed out their differences. And no doubt, both peace and justice now reign supreme in some Kingdom Far, Far Away. I live in a fantastical world, built from the ground up, molded and cast in my hopes and dreams. So, why not this

WikiLeaks disclosure sets off defensive posture in the international politics of Pakistan.

The recent news on Pakistan’s international relations that came out of the latest WikiLeaks document cache has been remarkably easy to bear. Nothing untoward has happened. All the players have played their parts. International politics between the U.S and Pakistan continues in recognizably similar ways as it did yesterday, and the day before. Of course, strategic politics has nakedly come to the fore and understandably so; the real news however is non-news–that though everyone has grumbled, moaned, they have all walked away into their own corners of politics and chicanery to hold onto their share of power in Pakistan

National intelligence estimate reaffirms Pakistan’s role in defeating Taliban

The latest National Intelligence Estimates (NIE) for Afghanistan and Pakistan report what most analysts of the region and the wars there already know: the U.S. intervention in Afghanistan won’t work unless the Pakistani government and military rounds up its Taliban allies and breaks the back of the various groups that constitute the Taliban in both Afghanistan and Pakistan

Evaluation of High Speed Hardware Multipliers - Fixed Point and Floating point

There is a huge demand in high speed arithmetic blocks, due to increased performance of processing units. For higher frequency clocks of the system, the arithmetic blocks must keep pace with greater requirement of more computational power. Area and speed are usually conflicting constraints so that improving speed results mostly in larger areas. In our research we will try to determine the best solution to this problem by comparing the results of different multipliers. Different sized of two algorithms for high speed hardware multipliers were studied and implemented ie. Parallel multiplier, Bit serial multiplier. The workings of these two multipliers were compared by implementing each of them separately in VHDL. A number of high speed adder designs are developed and algorithm and design of these adders are discussed. The result of this research will help us to choose the better option between serial and parallel multipliers for both fixed point and floating point multipliers to fabricate in different systems. As multipliers form one of the most important components of many systems, analysing different multipliers will help us to frame a better system with area and better speed.DOI:http://dx.doi.org/10.11591/ijece.v3i6.418

SAW Filter Modelling in Matlab for GNSS Receivers

Satellite navigation has enabled a great amount of new application for many users, but a lot of limitations have been observed regarding precision and integrity of navigation signals. Overall signals of different navigation systems (GPS, GALILEO, GLONASS signals) compose Global Navigation Satellite Systems (GNSS) Signal. Each of the satellite system has separate signal characteristics, but each signal needs to be compatible with the others to prevent interferences and attenuations between signals. The processing of all the signals is performed in same receiver. Hence, complex receiver design is required. In GNSS signals different frequencies are used for different satellite navigation systems such as GPS, Galileo and Glonass. When the group delay response is observed in SAW filters it shows that the signals lie on different frequencies have different delays. Manufacturers carried out measurements with respect to carrier wave but they have ignored the spreading codes or modulation. In this research, we will design a model for GNSS SAW filter in Matlab. This model can be use to obserce the delay of the signals. This model will allow the manufacturers to address these problems in the SAW filter software to optimise slope and magnitude of the design which will benefit the users of GNSS all over the world to get more precise positioning.DOI:http://dx.doi.org/10.11591/ijece.v3i5.364

Design and Simulation of Cascaded Class-A Microwave Power Amplifier

Microwave power amplifiers are the most significant components in wireless communications systems. As the technology continue to progress, the designers are facing new challenges and opportunities. The purpose of this work is to push the limits of efficiency and bandwidth of power amplifiers. The objective of this research is to design and build a prototype two stage Microwave power amplifier operated at 2.4 GHz with a linear region of operation up to our desired output of 0.5 watt or 27 dBm. The transistor used in the first stage is BFP540 while the output power of the first stage is the input of the second stage in which the ATF50189 transistor is used to for amplification. All the simulations and readings are taken by using AWR Microwave Office software. By using the load line Rl and the biasing points are achieved for both stages. The applications of our proposed device include many products in the field of microwave communications. One of the important applications of a Microwave power amplifier is in the output stage of a transmitter where a signal needs amplification before it is transmitted.DOI:http://dx.doi.org/10.11591/ijece.v3i5.364

A Study of the Organizational Stress among Public Sector Secondary School Teachers in Punjab

The aim of the study was to find out the factors which create stress among public sector secondary school teachers to determine the stressors being faced by the secondary school teachers. The study was related to the secondary schools of public sector in Punjab. Punjab province is comprised of 9 divisions. Due to limited time and resources, the study was delimited to public sector secondary schools of Lahore division. The study adopted descriptive survey design using a sample of 1000 teachers drawn from 100 secondary schools from public sector in Lahore division. From each school 10 teachers were randomly selected. One rating scale was developed to collect data for the study. The percentage, mean, standard deviation and t-test were applied as descriptive and inferential statistics to analyze the collected data. In the light of the results and conclusions of the study, it may be recommended that unwanted sounds and noise may be minimized in the school environment, trainings be imparted to the staff, workload should be equally distributed and necessary facilities should be provided at schools
