    Introduction to Software Engineering

    • Systematic Disciplined Quantifiable approach to development, operation, maintenance and retirement of Software (IEEE Definition)
    • 1968 – NATO Conference in Germany
    • Multi-person construction of multi version software (parnas)
    • A discipline that deals with the building of software systems that are so large that they are built by a team or teams of engineers (Ghezzi, Jhazayeri, Mandrioli)

    Definitions:

    A discipline that aims at producing fault- free software that is delivered on time within budget which meets the end- user’s requirements. Furthermore, it aims in producing easily modifiable software when the user needs change. (Schach)

    Historical Aspects:

    • 1967, a NATO group coined the term “Software Engineering”

    • 1968 NATO Software Engineering Conference concurred that “Software production should be an engineering-like activity”.

    • Using philosophies and paradigms of established engineering disciplines to solve “Software Crisis: that the quality of software was generally unacceptably low and that deadlines and cost limits were not being met”.

    Scope of Software Engineering:

    Economic Aspects

    • Software Engineering v.s. Computer Science

    • The computer scientist investigates several ways

    to produce software, some good and some bad.

    • But the software engineer is interested in only those techniques that make sound economic sense.

    For example: A coding technique that can execute very efficiently but with higher maintenance cost may not be a good choice.

    Maintenance Aspects

    • Software Life Cycle / Software Process

    • Requirements Phase

    • Specification (Analysis) Phase

    • Planning Phase

    • Design Phase

    • Implementation Phase

    • Integration Phase

    • Maintenance Phase (highest cost among all these phases)

    • Corrective, Perfective, and Adaptive Maintenance

    • Retirement

    Scope of Software Engineering

    Maintenance is so important, a major aspect of software engineering consists of techniques, tools, and practices that lead to a reduction in maintenance cost.

    Approximate relative costs of the phases of the software life cycle.

    12

    Specification and Design Aspects

    • Software professionals are humans, and humans can make error.

    • The fact that so many faults are introduced early in the software life cycle, highlights another important aspects of software engineering, namely, techniques that yield better specifications and designs.

    • For example, reducing specification and design faults by 10% will reduce the overall number of faults by 6-7%. Scope of Software Engineering

    Team Programming Aspects

    • Most software being developed and maintained by a team of software engineers

    • Scope of software engineering must also include techniques for ensuring that teams are properly organized and managed.

    • For example, team programming leads to interface problems among code components and communication problems among team members.

    Several techniques have been suggested to help solve the software crisis.

    ~1975-1985: Structured Paradigm

    • Structured Systems Analysis, Composite/Structured Design, Structured Programming, Structured Testing

    • Lead to major improvements for software industry.

    • But only good for small programs (say, 5,000-50,000 lines of codes)

    • Not scale well with today larger programs (say, 500.000-5,000,000 LOC)

    • Not so good in software maintenance aspects, (for instance, because of the separation of action-oriented and data-oriented in structured paradigm).

    Object-Oriented Paradigm

    • An object is a unified software component that incorporates both data and actions that operate of those data.

    Software

    • Set of instructions that run on a piece of hardware
    • Programs + documentation + test drivers + analysis and design documents

    How can you systematically develop software?

    How do you make this process cost-effective?

    Engineering

    • Process by which tradeoffs can be analyzed.
    • Optimization in one dimension might cause some other factor to be suboptimal.

    Three Major dimensions

    • Project Cycle time

    • Cost

    • Quality of the software

    For a project that is already delayed, employing more number of people further delays the process

    Characteristics of Software

    Does not wear out

    • However it becomes obsolete

    Needs to be custom built

    • Software ICs – reality?

    Maintenance costs are high

    Software productivity

    • Average to expert programmer 25:1

    Bug fixing cost is nonlinear Mythical Man-month (Fred Brooks)

    • Published in 1975, republished in 1995.
    • Marge programming projects suffer management problems different in kind than smaller ones, due to division of labour
    • Critical need is the preservation of conceptual integrity of the product itself
    • The difficulties that are inherent in software development
    • Nurturing great architects and designers

    Numerical Methods - Solution of equations & Eigen value problems

    Introduction :

  • Numerical Methods play an indispensible role in solving
    real life Mathematical, physical & Engg. Problems. Sometimes, the analytical method fails or unable to give desirable solutions to such problems. In such cases, we go for numerical methods.
  • The  aim  of  numerical  analysis  is  therefore,  to  provide constructive methods for obtaining approximate answers to such problems, using only simple arithmetic operations.
  • The advent of digital computers has, however, enhanced the speed and accuracy of numerical computations.
  • Solution of equations & Eigen value problems

  • In this chapter, we find: learn some method(s) to
  • The root of an algebraic & transcendental equation f(x) = 0
  • The solution of linear simultaneous system of equations
  • Inverse of a matrix
  • Eigen value of a matrix.

    FOURIER TRANFORMS

    Motivation and Background:

    In mathematics a transform is an operator applied to a function so that under the transform certain operations are simplified. In higher mathematics this idea is applied to functions in order to solve certain types of differential equations, for example, the Laplace transform.

    clip_image002

    Another type of transform used to simply the process of solving differential equations is called the Fourier transform. Jean Baptiste Joseph Fourier (March 21, 1768 - May 16, 1830) was a French mathematician and physicist who is best known for initiating the investigation of Fourier series and their application to problems of heat flow. The Fourier transform is also named in his honor.

    Fourier analysis has many scientific applications — in physics, number theory, combinatorics, signal processing, imaging, probability theory, statistics, option pricing, cryptography, numerical analysis, acoustics, oceanography, optics and diffraction, geometry, and other areas. When processing signals, such as audio, radio waves, light waves, seismic waves, and even images, Fourier analysis can isolate individual components of a compound waveform, concentrating them for easier detection and/or removal. For example, Telephone dialing; the touch-tone signals for each telephone key, when pressed, are each a sum of two separate tones (frequencies). Fourier analysis can be used to separate (or analyze) the telephone signal, to reveal the two component tones and therefore which button was pressed.
