MWSN is an emerging area of research and most of the work in the field of MWSN is done at the simulation level as there is hardly any cost effective hardware platform(node/mote) available for MWSN applications. To handle mobility, the MWSN node should be much more efficient than the nodes in static WSN. Moreover, a MWSN node should be capable of handling real time mobility control, path planning and...
This paper proposes an efficient bank of filters derived from variable bandwidth filter structure, for audiogram matching in a digital hearing aid. The variable bandwidth filter is designed using Farrow structure, for lower hardware complexity. The magnitude and band edge frequencies of the filters are independently adjustable which allows this arrangement to successfully fit a given audiogram with...
In conventional buck-boost converters, the output voltage is inverted. Hardware circuitry or microcontrollers are used to trigger a switch in the converter. In the proposed study, a non inverting buck-boost converter is implemented for PV system. The Pulse width modulation (PWM) signals for two MOSFETS in the converter are generated by DSP TMS 320 2808. Depending on the solar panel input, buck-boost...
Green energy sources such as solar — PV, wind, fuel cell, battery, ultra capacitor etc. are highly recommended in hybrid electric vehicle applications. Power electronic converters play an essential role in the incorporation of these green energy sources in to the vehicle system. Design and analysis of a non-isolated dual input DC-DC converter for the integration of nonlinear V-I characteristic DC...
Due to the bandwidth efficiency and high robustness in delay dispersive multipath fading channel, the OFDM system is most widely adopted by different digital communication systems, as their main modulation technique. The major problem in the OFDM system is its sensitivity to the channel conditions, hence leads to synchronization errors. The main problems are ISI and ICI, due to delay dispersion of...
The resource constrained applications in the present day communication networks demand the use of new cryptographic protocols and hardware with reduced computational and structural complexity. The use of standard, standalone cryptographic primitives are not suitable for such applications. This paper proposes the implementation of a new integrated system for both encryption and authentication based...
Security, reliability and hardware complexity are the main issues to be addressed in resource constrained devices such as wireless sensor networks (WSNs). Secure channel coding schemes have been developed in literature to reduce the overall processing cost while providing security and reliability. The security of a channel coding scheme against various attacks is mainly decided by the nature of intentional...
Histopathological examination is the gold standard for many kinds of cancer diagnosis as the histopathology slides provide a cellular level view of the disease. Computer-aided automated diagnosis techniques have recently been developed based on the analysis of skin histopathological images to diagnose skin cancer. Due to the very high resolution characteristics of the skin whole slide images, the...
