    Abstract

    The main objective of this work is to design and construct a microcomputer
    based system: to control electric appliances such as light, fan, heater,
    washing machine, motor, TV, etc. The paper discusses two major approaches to
    control home appliances. The first involves controlling home appliances using
    timer option. The second approach is to control home appliances using voice
    command. Moreover, it is also possible to control appliances using Graphical
    User Interface. The parallel port is used to transfer data from computer to the
    particular device to be controlled.

    Abstract

    Wimax (Worldwide Interoperability for Microwave Access) is a promising
    technology which can offer high speed voice, video and data service up to the
    customer end. The aim of this paper is the performance evaluation of an Wimax
    system under different combinations of digital modulation (BPSK, QPSK, 4 QAM
    and 16 QAM) and different communication channels AWGN and fading channels
    (Rayleigh and Rician). And the Wimax system incorporates Reed Solomon (RS)
    encoder with Convolutional encoder with half and two third rated codes in FEC
    channel coding.

    Abstract

    At present, the mostly used and developed mechanism is hardware
    virtualization which provides a common platform to run multiple operating
    systems and applications in independent partitions. More precisely, it is all
    about resource virtualization as the term hardware virtualization is
    emphasized. In this paper, the aim is to find out the advantages and
    limitations of current virtualization techniques, analyze their cost and
    performance and also depict which forthcoming hardware virtualization
    techniques will able to provide efficient solutions for multiprocessor
    operating systems.
