Department of Computer Science, Virtual University of Pakistan

Abstract– Software development is a critical task that requires a detailed and well-structured guideline in the form of software development process model. A good software development process model can play very important role in developing high quality software. Traditional software development models like Water fall, RUP, V-Model and Spiral Model remained dominant in software industry for a long time but to cope with growing needs and technology change in software industry, software developers tried to explore more improved software development models that lead to advent of agile development models. Agile models were warmly welcomed by software community because of their focus towards customer satisfaction, changing requirements and early software delivery. This paper provides a comprehensive review of different agile models which are used in software industry.

Abstract– Edifice today is characterized by a lot of physical and digital development ranging from simple door bell to access code, burglar alarm, robotic assistance etc. Burdening on these; this paper examined the evolution of digital edifices (herein used synonymously as houses) starting from its very origins- shanks and adobe-, why they are called smart, the architecture built into them to make them intelligent and smart and the effect of being smart with an attempt to predict what the future holds for smart and intelligent edifices. Along the line of research and analysis, it was discovered that the body scanning machine could do more in keeping the body log of subject or visitors to an area which could subsequently help in weight monitoring. We also proposed and designed a hybrid or combination biometrics for a better access control, footwear (shoes), mattresses and subject body recognition, auto-swing walls and concluded on the future technological considerations in this paradigm.

Abstract– Visual Detection and tracking of human body movement is a key technology in several areas. Because of many potentially important applications “Looking at People” is currently one of the most active application domains in computer vision. This trend is motivated by a large range of application such as, Security Surveillance and HCI (Human Computer Interaction). In this paper, we propose a design for the detection and tracking of the moving object. This is system based on the two main parts. One is the software and other is the hardware. In software part the algorithm is implemented, which detects the object, if the object move and goes out of the focus then the signal goes to the hardware which rotate the camera in that direction and track the object continually. We will assume that the motion of the tracked object will be constant and camera will be tracked up to 180 degree. The main goal of the paper is to implement an efficient and fast human detection and tracking algorithm and interface it with hardware.

Critical Review of the IMO on Ballast Water Convention and its Impact on Shipping

Abstract– Today, 90 percent of global trade is carried out by sea transport. According to statistics, every year, about 10 billion tons of ballast water is carried by ships and it is estimated that, on a daily basis, at least 7,000 species of living organisms are transmitted in this way from one place to another. Regarding to this global crisis, the International Maritime Organization (IMO) commenced its activities from 1973 through its country members in regard to formulate a convention to address the issue of Ballast Water contamination problem, known as MARPOL convention. Finally, in February 2004, an International Convention on "Control and Management of Ballast Water and Its Sediments" was legislated. Ballast water, has always caused substantial economic losses and environmental degradation. One of the best ways to tackle this global problem is to avoid using ships with Ballast Water tanks which are designed by Research Centre of Japan. The naval Japanese engineers, have invented a new hull system known as The Non Ballast Water Ship (NOBS).

Detailed Harmonic Analysis for Pulse Width Modulation based AC to AC Matrix Converter

Raheel Muzzammel and Muhammad Saeed Akhtar Khan

Department of Electrical Engineering, University of Lahore, Lahore, Pakistan

Abstract– Converters are used in wide range of applications to save energy and attain desirable voltage. Matrix converter can convert three phase AC input to three phase AC output with variable voltage amplitude and frequency directly. It can be used as bidirectional power flow converter without any intermediate storage element. The objective of this proposed research is to minimize the harmonic losses to get maximum output voltage ratio, sinusoidal current, desired variable voltage amplitude and desired variable frequency. Pulse width modulation algorithm controls the input, output voltage and frequency independently. In this work, pulse width modulation based matrix converter will be designed to attain voltage ratio up to 1 and to reduce switching losses so that low total harmonic distortion could be achieved with sinusoidal waveforms of desired amplitude and frequency. Simulation environment will be created in Matlab.

Keywords— Matrix Converter, Pulse Width Modulation, Total Harmonic Distortion and Matlab
