Tuesday 2014/12/16 -- A Dark Day in Our National History

HITEC University students, staff, and faculty gathered -- silence and dua for shuhda-e-APS-Peshawar.

Computation of Enhanced Vegetation Index Using Spectral Python

This example was demonstrated in masters level course GIS and Remote Sensing, See references for details. Most of commands are taken from user guide [SpectralPython] whereas theoretical basis are discussed in [MODIS-VI_UserGuide]. This post assumes software is already installed and data is locally available. Invoke ipython --pylab=wx at command prompt.

In [1]: from spectral import *
In [2]: img = open_image('92av3c.lan')
In [3]: blu, red, nir = img[:,:,9], img[:,:,29], img[:,:,43]
In [4]: evi = 2.5 * (nir - red) / (nir + 6 * red - 7.5 * blu + 1)
In [5]: view = imshow(evi)

An Implementation of DFT in Python

This paper I wrote recently to challenge myself on use of Python programming language for implementation of Fourier transform -- a basic signal processing tool. The document can be accessed by website link [PAPER].

Python Code for Quadratic Equation

Writing code to find roots of Quadratic equation was a famous assignment when I was learning GW-BASIC and Borland Turbo C. Recently, I have written following Python code. The output of two sample executions are pasted below as well.


# Quadratic equation with real and non-real roots
# Written by Dr. Tariq Javid as of 31 July 2014

a = raw_input('enter a: ')
b = raw_input('enter b: ')
c = raw_input('enter c: ')

a, b, c = int(a), int(b), int(c)

if ((b ** 2) < (4 * a * c)):
    a, b, c = complex(a), complex(b), complex(c)
    x1 = ((-b) + ((b ** 2) - 4 * a * c) ** (0.5)) / (2 * a)
    x2 = ((-b) - ((b ** 2) - 4 * a * c) ** (0.5)) / (2 * a)
    print 'imaginary roots:'
    print x1
    print x2
else:
    a, b, c = float(a), float(b), float(c)
    x1 = ((-b) + ((b ** 2) - 4 * a * c) ** (0.5)) / (2 * a)
    x2 = ((-b) - ((b ** 2) - 4 * a * c) ** (0.5)) / (2 * a)
    print 'real roots:'
    print x1
    print x2

A SHORT INTRODUCTION TO E-LEARNING

This is another article for Better Pakistan published by Thinkers' Forum Pakistan. This article aims novice to consider taking an on-line course and provide quick guidance on the process. [Article Link] 

A MIGHTY TRIPLET: PEN, KEY, AND MOBILE PHONE

Today, I am able to complete a one page write up. This article is intended for Better Pakistan published by Thinkers' Forum Pakistan. I am greatly inspired by Secretary General Colonel (R) Bakhtiar Hakeem SI(M). [Article Link]

A Presentation on eLearning with Moodle for HITEC University Faculty

This gives me a great feeling at this point in time as finally this presentation is ready. The presentation is for faculty members in Department of Mechanical Engineering of HITEC University. It was initially agreed in senior management meeting a while ago that I will be delivering a presentation as per Dr. Kamran HoD ME request. The objective is to use this wonderful eLearning platform effectively and with ease. [LINK]

First Convocation of HITEC University on 08 February 2014 at Jinnah Convention Centre Islamabad

That was a great event. I must say well organized and excellent work by HITEC executives, faculty, and staff. I must say students contribution with attending parents and relatives are also very great. I also recalled, NUST convocation (15 April 2010) when I received my PhD degree [POST]. The photo below is a record for my memory.

A Presentation on Introduction to Software Defined Networking (SDN) Architecture

I have created a presentation on software defined networking (SDN) architecture. This presentation contains hands-on stuff. [LINK]

A Presentation on Decision Making with Fuzzy Information

Fuzzy sets, logic, and systems inspired me as these have shown potential to convert human perception into mathematical model. This presentation shows my progress. [Presentation Slides] 

Microprocessor and Interfacing Techniques (Fall 2013, Lecture Slides, and Student Mini Project)

This was a great experience as course covered basics of Intel microprocessors with x86 assembly language and Atml AVR microcontroller with C language programming for ATmega32. To access lecture slides archive, click MPnIT-lecture-slides; and to access a student mini-project, click student-mini-project.  

PhD Convocation Pictures

I found following pictures from my PhD convocation. The event was held at Jinah Convention Center, Islamabad on 15 April 2010. I still remember handshake with General Ashfaq Pervez Kayani who was the chief guest.

How to Get a Job?

The HITEC University students has celebrated this week from 30 Dec 2013 to 03 Jan 2014 as Science Week. A number of events including my presentation on How to Get a Job? I was front of a large number of students and faculty members. It was gone nice and concluded with appreciation by students and Dean Engineering and Technology. Notably, students have asked very good questions.
